Black technology starts from the steel suit

Chapter 133 133 Sales Problems Are Technical Problems

"The mechanical sensors and acousto-optic sensors we added to the design are quite sensitive. At the same time, we have also specially written safety restrictions in the control system scheme, even if it is damaged due to this, the safety of personnel must be guaranteed."

"In the last 7 days, we conducted a simulation test, in which 80 robotic arms were able to stop smoothly anytime and anywhere, without causing any damage, only once because the hair of the dummy was curled in, but it also stopped quickly , a few hairs may have fallen out..."

"Of course, there must be a price. Three of the robotic arms have been damaged to varying degrees. If you want to restore them, you will need to pay about 4.5 to 5 yuan in maintenance costs."

"This is acceptable. After all, it is people-oriented. If the machine breaks down, it can be repaired. If the man breaks down, there will be big problems." Wang Feng agrees with Brother Wei's approach very much.

However, Wang Feng finally chose to believe his own eyes. He stayed in the factory for a whole day. During these 12 hours, he did not leave the testing area. The 80 mechanical arms were not only inspected by local people. , at the same time, there are third-party testing agencies invited by Wang Feng, or other manipulator manufacturers, and their main supply targets in the future: those large machinery manufacturing factories and foundries, various assembly factories, etc. Wang Feng was familiar with them, so he sent out invitations.

Therefore, this test is not only for him to see, but also for these potential buyers. After all, once something is made, it must be sold. Only in this way can we create value and profits, and continue to support the further development of the institute.

It's just a pity that even though they stayed in the factory for a whole day and saw the excellent performance of these machines with their own eyes, they didn't make a decision right away, they just declined and said they needed to continue to observe more.

Thanks to the policy dividends of industrial upgrading and technological transformation, they have all received large loans to support the transformation and upgrading of factories. This is a big piece of cake, and many people are staring at it.

Therefore, they said that they need to communicate further with the superior department, and then submit the data, reports, and test videos to the technical department for testing, and finally discuss with the board of directors before giving a final answer.

And a robot is not cheap. Take the two types of robotic arms they currently design, the price of the 6-axis industrial-grade robotic arm is more than 20 yuan, and the price of the high-precision 7-axis robotic arm is more than 30 yuan. , This is still when the production reaches 2000 units and the cost is amortized, so this kind of procurement is a matter of life and death for an enterprise.

"Then wait for your good news." Wei Mingli smiled and shook hands with each other one by one to bid farewell. After all, there is no righteousness in buying and selling. Maybe everyone will use each other at any time. It is also necessary to leave a good impression of.

It was already late at night when only the two of them were left.

"I originally wanted to borrow your name, but it doesn't seem to work." Wei Mingli said with some emotion: "When it comes to this kind of big money, no matter which company it is, it is very cautious!"

"I said why did you ask me to invite all these people here in the letter? So that's the idea!" Wang Feng couldn't help but feel a little funny. Sure enough, the men who are going to get married are different. The most obvious change is the love for money. Attitudes have changed.

"Actually, taking a step back, this is not necessarily a bad thing." Wang Feng paused: "Think about it, even if the products of our research institute are not good, don't they even give me this bit of face?"

"Could it be?" Old Wei was also a thoughtful person, and he immediately reacted after hearing Wang Feng's words.

"They didn't make a hasty decision, which just shows that they intend to make large-scale purchases, and they dare not make decisions without authorization only when such major interests are involved."

"Otherwise, with their current status, do they need to be on the board of directors for tens of millions of purchases?"

"It makes sense. I'm too pessimistic!" Wei Mingxi thought for a moment, and then realized: It's different from working with those not-so-good factories before. After all, he is following the big guys now, and he doesn't look at the monk's face. Looking at Buddha noodles, even if they are just showing off, they will order dozens or even hundreds of them for each family.

But after thinking about it, he can't be blamed for this. After all, although he is a student of the Nobel laureate, in this era when there is no shortage of national inflation, people really don't necessarily care.And the shrinkage of the domestic machinery manufacturing industry is indeed an indisputable fact.Under such circumstances, he would not dare to make a hasty decision like this.

Not to mention other aspects, but in terms of industrial robots represented by mechanical arms, there are currently two major problems: "Where are the difficulties of mechanical arms?" Is the arm not made well enough?" This is a problem for the entire domestic robotics industry.

What are the difficulties of industrial robots (mechanical arms)?

sport control:

To some extent, the performance of a robot is determined by the level of motion control. Some people say that "a robot is a software product", which is what they mean.The gap in control, as a simple example, there are not many companies in China that can do a good job in dynamics, and ABB has already realized model control based on dynamics on the S1994C controller launched in 4, that is, the first generation QuickMove and TrueMove technologies have been updated to the second generation.

Other functions or features such as dynamics, error compensation, friction compensation, force control, and drive-control integrated design are relatively mature in foreign brands, while domestic manufacturers are still in their infancy in these aspects.

Mechanical/Electrical:

Structural optimization design, most of the driving force of the motor on the mechanical arm is used to overcome its own gravity to do work. Under the condition of ensuring the rigidity, the quality of the mechanical body can be reduced by optimizing the design, which can improve performance and reduce power consumption.Taking a typical desktop robot with a load of 6kg as an example, Fanuc’s 200iD 7kg-717mm arm span model has a self-weight of only 25kg, and there is still a big gap between domestic products and this level.

Assembly is mainly a process issue. Robots sound high-end, but most manufacturers still use traditional manufacturing ideas to make robots. The entire production process management system is outdated and lacks the spirit of "craftsman". In the end, it is impossible to guarantee high-quality products. consistency.

Other cable routing and reliability (most problems with the robot are related to cables and connectors), appearance design, protection and heat dissipation of the teach pendant/control cabinet, etc., are also points that require manpower and material resources to study.

security function:

The most important feature of human-machine collaborative robots is safety. There are collaborative robots with similar appearances in China, but they do not provide corresponding safety functions and certifications.

Due to the lack of a corresponding mandatory certification system, domestic robots generally do not have the characteristics of intrinsic safety, and there are few products that have passed European and American safety certification.Of course, this has a lot to do with domestic users' disregard for security.If domestic robots want to go abroad, safety certification is a hurdle that must be crossed.

So it seems that what he encountered was a sales problem. In fact, from his point of view, it was a technical problem!
