v2 Chapter 433： Mu Yang: My talent is cheating

Latest URL:

In mid-November, the industrial robot control system and welding system designed by Muyang were debugged.

The parts of the sample trial production have been processed and painted, and the assembly is started.

General industrial robots have 6 axes, and there are also 7 axes, but very few.

The accessibility of 7-axis is higher, but in general, it is 6-axis, which can meet the requirements of use.

One axis represents a joint that can rotate, and 6 axes are 6 rotating joints. Usually, the 6th axis is equivalent to the human wrist.

Each axis is driven by a servo motor, and there are 6 servo motors for 6 axes, and the motor power of each axis is different.

Due to mechanism interference, the rotation range of each axis is limited. Like the first axis, it is generally around 330 degrees, and it cannot rotate 360 ​​degrees in one circle.

Xinghai Group's first welding robot is named "XH1400", "1400" indicates the range of arm movement, and the maximum reaching distance of the sixth axis is 1400 mm, which is actually 1437 mm.

The total power of the six motors is 3400, and the weight of the industrial robot is 155 kg, which is 15 kg lighter than the counterpart Panasonic welding robot TM1400, with a more compact structure and a larger range of motion.

The repeat positioning accuracy of the design is plus or minus 3 wires, which is higher than the plus or minus 5 wires of TM1400.

It is not yet known how well the final assembly works.

During this period of time, Mu Yang mingled with the scientific researchers of the industrial robot laboratory, chatting while debugging the equipment.

Before the change, Mu Yang didn't have that leisure time, there are a lot of things in the company waiting for him to deal with.

Now, he can devote himself to scientific research.

Everyone is familiar with the chairman and can chat about everything.

Especially a few young employees, who are similar in age to Mu Yang, and there is no communication between them. They even asked Mu Yang if he likes to play basketball or football.

Mu Yang smiled, "Basketball is alright, I can play basketball once in a while, I can't play football, but I like watching the World Cup."

"Hey, next year is the World Cup, but it's a pity that we don't have our national team."

"There is no regret, we went with the ball, but not the people." Mu Yang joked.

"Haha, the chairman is right, we went to everything except the players."

"There are two ball games in our country that are invincible in the world, one is table tennis, no one can beat it;

The other is football, which no one can beat. "

"Haha, the chairman is really humorous."

"Tell me, do you think Messi can win the championship next year?"

"It's too difficult, it's too difficult to rely on him alone." Mu Yang replied, Mai Xi is great, but when all the teammates rely on him, it's hard to win, sometimes it's good to be able to draw, Counting on offside teams is unlikely.

Unless, Macy can open and hang.

"Chairman, aren't you optimistic about Mai Xi?"

"It's not that I'm not optimistic about it, but I'm not optimistic that his national team can win the championship. For football, it's not enough to rely on one person alone. What if his team is not good enough.

Football is prone to miracles, it depends on whether you can grasp the fleeting opportunities, and so is life. "Mu Yang wanted to watch the World Cup live, but forget about the danger of going abroad. In his life, it would be difficult for him to go abroad.

"Chairman, are you planning to invest in a football team?"

Mu Yang laughed and shook his head, "Forget it, I'm not that interested."

Everyone debugged the equipment while chatting, and Mu Yang sometimes participated in the hands-on work. For those who like machinery, if you let him stand and watch without doing anything, his hands will itch.

If he likes to play with machinery, he would operate it by himself, so Mu Yang didn't put himself in a high position, which made it difficult to get along with the employees.

Mu Yang also asked the scientific researchers in the laboratory to do more work. Only by doing it will they find more problems.

Even an engineer who is engaged in design needs to go to the workshop frequently, and needs to assemble and operate the things he designed.

If Mu Yang doesn't like machines, then he doesn't like machines either.

I'm too lazy to get started, and I don't even want to come to the laboratory.

After all, he made the control system and the teaching pendant by himself, and it was only after he started debugging that he knew where there was a problem with his design.

We talked about the World Cup for a while, and then we talked about industrial robots.

"How much is the global sales volume of industrial robots?"

"About 200,000 units last year."

"It doesn't look like much. The market size of 30 billion yuan is far less than that of the automobile industry."

"It's really not big, but its role cannot be ignored. Modern intelligent manufacturing can't do without it, and there are some complex environment jobs, such as high-temperature forging, which are too dangerous to operate manually. "

"The island country next door can be regarded as the country that uses the most robots in the world, with about 300,000 units, followed by the beautiful country and the country with 160,000 units, and the country with 140,000 robots."

"Island countries do have advantages and disadvantages. I have to admit that their intellectual development is faster than that of Germany."

"Our country has 130,000 units, the fifth in the world. The density is very low and the development is fast. It is estimated that it will become the world's number one in a few years, but the density is still far behind developed countries."

"Chairman, can the robots of the four major brands operate?" an engineer asked Mu Yang.

Mu Yang said lightly, "Well, it's okay, I'm not very skilled."

Yin Zhi, the technical manager, said: "Xiao Liao, the proficiency in the eyes of the chairman is compared with the World Skills Competition. If you say you are proficient, you must be number one in the world; Years of operators are not much different.”

"Wow, that's really amazing. Chairman, how did you practice? Is this talent?"

"Maybe I used to make some things by hand when I was a child, and it's faster to get started. I don't think it's talent. Practice makes perfect. Besides, many things are similar. If I can operate a brand of teach pendant, I can get started with other brands. It will be very fast, but KUKA is more troublesome and not suitable for welding." Mu Yang Le Youyou said, he can operate two brands of industrial robots, and he is more familiar with the opening and closing.

For him, his talent is cheating.

However, for his level, this is nothing to show off. It's just that for these scientific researchers, theoretical technology is a normal operation, but operation is a real comparison. After all, they are not workers.

For the next few days, Mu Yang spent all his time in the laboratory.

The assembly of the robot is not complicated. Many parts are produced in modules. As long as the parts are ready, two or three people can assemble them in a few days.

If the assembled equipment is shipped to the site, two people can install and debug the industrial robot and welding machine in one day.

A piece of equipment is not very expensive. If it takes several days to assemble a piece of equipment, the service cost is too high.

There are a total of 100 R&D personnel for the industrial robot project, and only a dozen scientific researchers responsible for on-site testing and installation.

By the end of November, the Industrial Robotics Laboratory had assembled two XH1400 welding robots. The arc welding system of the robot was matched with the arc welding machine produced by our company, which made it easier to use.

On the afternoon of November 25th, Mu Yang will come to check and accept the equipment.

"Chairman, may I ask how much we can sell this set of welding robots?" A test engineer asked Mu Yang.

"A hundred or two hundred thousand. The specifics are determined by the marketing department. We just need to make a prototype. If the prototype is debugged and passed the acceptance, it will be up to you for mass production."

The current Mu Yang is only responsible for solving the core technology. As long as the prototype debugging is OK and the acceptance is passed, his task will be completed.

There are many types of industrial robots. In terms of arc welding robots, the load of 6KG has met the market demand of most arc welding machines. On the basis of XH1400, the personnel of the project team will develop another model, XH1800, with a larger working scope.

In short, Mu Yang doesn't need to worry about the expansion of the model.

"Okay, during this time, after the chairman joined in, the research and development progress was many times faster."

"Don't get too excited, let's start the test welding. Whether you can beat the OTC depends on this equipment." Mu Yang waved his hand and ordered to start the test welding.

"OK."

The skilled test engineer installs two T-shaped carbon steel plates with a thickness of 10 mm and a length of 200 mm each that have been spot-welded firmly on the working platform, and then adjusts the teach pendant to manual mode to teach programming and welding process The parameters are set to current 160A, voltage 22V, welding speed 50CM per minute, no swing.

Only two fillet welds need to be welded, and the teaching programming is very fast, and it can be done in two or three minutes.

After programming, go again to prevent programming errors from hitting the gun.

If it collides with the gun, it will be an accident. It will damage the welding gun head and the sixth axis, and it will cost more than 10,000 yuan to replace it. You must know that the robot will not stop automatically, only by manually pressing "emergency stop".

The test engineer adjusted the teach pendant to automatic mode, reminded everyone to stand far away and not to watch the welding, and then pressed the external button "Start".

If you look at the welding arc light without a protective mask, it will hurt your eyes.

At this time, there was a "sizzling" sound from the welding place, and a large arc flashed at the nozzle of the gun tip, flashing and flashing.

"For boards over 3 mm, you don't need to use pulse mode welding, just use DC welding." Mu Yang stood aside and reminded. "Hey, I forgot."

The test engineer was a little embarrassed, "Chairman, you really understand, you can see it right away."

"What's the point of guessing? Your flickering welding arc is not pulse welding."

Mu Yang replied that if it is pulse welding, the arc light is not continuous, but flickering. Even if you don't look at the arc light, the workers work in this environment for a long time, and their eyesight will be more likely to get tired.

After the program is finished, the robot will automatically end the welding.

Everyone came closer to watch the welding effect, and the welding was okay.

"Try another piece of welding. The effect is completely achieved by welding with a welding machine. If you use a welding machine that is inferior, it may not be able to weld well." Mu Yang said.

An employee took the pliers to remove the welded workpiece, and then assembled a T-shaped plate. The test engineer saw that the position of the installed workpiece had not changed, so there was no need to change the program. He only needed to change the pulse welding of the arc welding machine to DC welding. That's fine.

After a while, start welding again.

This time, the welding arc did not flicker, but a continuous arc, which could be judged from the reflected light around it.

Mu Yang took the protective mask and was about one meter away from the welding arc to observe the changes in the welding pool.

At the same time, high-speed cameras are installed around to take pictures, and testing instruments measure and record the welding process. However, experienced welders can judge whether the welding fusion is good or not by directly observing the dynamics of the welding molten pool.

After a minute or two, the soldering is over.

The weld is a fillet weld with a leg size of around 5 mm, very even, the surface of the weld is not slippery, and importantly, there is no spatter around and the edges are well fused.

"We are welding carbon steel, which is the easiest to weld, and we are still welding horizontally. Try vertical welding, experiment with materials that are more difficult to weld, and also test swing welding, especially when the swing frequency is fast, to see if it can be achieved. The swing of the complex trajectory, this is the difficulty.

The OTC welding robot cannot swing when the frequency exceeds 5. The whole machine shakes very badly, and it is impossible to realize various complicated swing trajectories. At present, only ABB robots can realize it.

After the result comes out, report the result to me, and I will come to check and accept it.

Now, you have only initially completed the staged tasks, and have not yet completed the tasks. "Mu Yang confessed that more complicated tests cannot be tested in a short while.

Estimated to take a week.

Another five days later, Mu Yang received a report from Yin Zhi, the technical manager of the industrial robot project team.

Test passed!

It took Mu Yang half a day to go to the laboratory for inspection and acceptance, and indeed no problems were found.

It can be said that Xinghai Group's arc welding robot has been successfully developed.

There are many industrial robots

In addition to arc welding (gas shielded welding) robots, there are argon arc welding, handling, palletizing robots and so on.

But no matter what, these robots use the same control system and the same teach pendant. The moving and palletizing system is much easier than the welding system, and Mu Yang does not need to develop it himself.

So, Mu Yang's mission in industrial robots has been completed.

In general, the XH1400 arc welding robot has higher precision, better motor performance, strong overload capacity, good stability, and the best algorithm than other robots of the same type.

Especially the algorithm, which affects the motion control system, is also a difficulty for robots.

The trajectory of welding swing is actually the same as when a car takes an S-curved road. If the chassis is not good, the car will shake very much.

The same is true for the robot. If the stability is poor, when it is running fast and the swing frequency is very high, the shaking is very large. If it is a domestic robot, it feels that the whole shelf is going to be loose.

"Congratulations to everyone for completing the staged victory. You can celebrate tonight." Mu Yang asked the on-site personnel to gather together and praise them. "The experimental data must be collected well. Whether it fails or succeeds, it is your valuable experience."

After Mu Yang finished speaking, he explained to Yin Zhi and left the industrial robot laboratory.

After seeing the chairman leave, a test engineer said to Yin Zhi, the technical manager:

"Boss, after the chairman joined in, our scientific research has progressed much faster."

"Yes, this is why the chairman stepped down from the position of president and turned to scientific research. The chairman is a top scientist, a top expert, not just a great entrepreneur." Yin Zhi agreed, "This also reflects It turns out that our level is really not very good and we need to work harder.”

"Well, if there is no chairman, our technical level will be top-notch in the country. With the chairman, it will rise two grades."

Yin Zhi said solemnly, "This can't be helped. If it was that easy, other domestic robot companies would have developed top-notch industrial robots long ago, and they would not be overwhelmed by the four major brands of robots. At present, our company only has colleagues in the laser and material project teams. Can be more sophisticated on the basis of the original technology ~ www.novelhall.com ~ to develop more advanced technology, no longer rely on the chairman, other project teams are still working hard.

Our project team was established relatively late, and I don't want to be ranked last.

In the next year, we must have a thorough understanding of the technology of industrial robots, and we will be successful if we can truly develop more advanced industrial robots without relying on the chairman.

Now, nothing to be proud of.

However, everyone has been exhausted in recent months, and the team building at night. "

"Good!"

…

Mu Yang returned to his home on the 101st floor of Xinghai Building from the industrial robot laboratory, and took a hot bath in the bathtub.

Since resigning from the post of president, he often spends time in the laboratory, no longer wearing a suit, but a casual sportswear, which is easier to move around.

The company's first self-developed industrial robot has finally come out. If the OTC executives know about it, they will probably panic.

The research and development of industrial robots is completed, and Muyang's current research and development focus is only on industrial master machines.

As for chip manufacturing and design, as well as aero engines, that is after reading system level 7.

Being able to make industrial robots does not mean that you can do a good job in intelligent robots, it just means that another basic work has been completed.

In the next few days, Mu Yang spent most of his time on the reading system. Since the reading system was upgraded to level 6 on January 1, 2011, it has been almost three years now, and there is still more than 300 million experience points to upgrade to level 7. class.

He is particularly looking forward to what functions the reading system will have when it is upgraded to level 7.

My mentality every day is almost the same as when my wife is about to give birth. I feel that life is like years, and I hope to upgrade soon.
