From black technology to super engineering

In Nuoda's workshop, countless injection molding machines are working with the assistance of mechanical arms, and there is an indescribable smell and special sound of mechanical operation in the air.

Ye Ming tightened his mask, and under the leadership of Director Jia, he and Yang Chaoxiong walked into an injection molding machine.

"Our APS system uses Anlei...the principle...doesn't need my introduction?" Director Jia looked at the two and smiled: "It's actually an industrial scheduling system, which is responsible for integrating ERP (Enterprise Resource Planning ) and MES (Manufacturing Execution System), these enterprise production systems, the problem we are going to solve this time does not involve this, at best it only involves the manufacturing system.”

"Well, now the manufacturing industry is indeed moving closer to digitalization and informatization." Yang Chaoxiong echoed casually while walking towards the finished product port of the injection molding machine.

In the middle of the conveyor belt, there is a special mechanism similar to a machine tool, which consists of a light source and a lens. The pick-up robot arm on the side is continuously taking out a row of automatically fixed plastic spoons from the exit and placing them under the lens. After staying for a second, the robot arm puts down the spoons and continues to pick up the pieces.

The "passed" spoons continue to enter the next process through the conveyor belt.

Seeing this assembly line, Ye Ming... was taken aback for a while.

Didn't you say that you specialize in the production of plastic parts for pure electric vehicles? What is this row of spoons...

"The problem now is the recognition preparation, right?" Yang Chaoxiong asked, pointing directly at the machine vision system, unlike Ye Ming.

"right."

"Then... is there a problem now?"

"It's okay to use it to check spoons. After all, our technology for producing these daily products is very mature, and even if there are occasional flaws, it's not a big problem. But it's not enough to replace it with a slightly more complicated mold, even if you use AI to learn Neither."

"AI learning?" Yang Chaoxiong and Ye Ming glanced at each other, looked around suspiciously and said, "I haven't seen a PC, you don't have an AI chip in it, do you?"

Yang Chaoxiong pointed to the machine vision system that looked a bit silly and clumsy—it looked like a shoulder-mounted camera, and it was impossible to install an AI chip at first glance.

"Uh...there's a recognition system inside." Director Jia paused as he spoke, "Let me demonstrate it to you."

"Then trouble Director Jia."

...

...

Three hours later, Director Jia drove Yang Chaoxiong and Ye Ming back to the downtown hotel.

The two declined Director Jia's kindness to invite them to dinner, went straight back to the room, ordered a takeaway, and then dialed Professor Tang's video.

"Teacher, do you think we should tell the truth, or what should we say?"

When the two told Professor Tang about the situation here, Yang Chaoxiong threw the problem to the teacher.

——In the afternoon, they spent three hours and finally figured out what this system was.

To put it bluntly, the factory is probably being "thumb".

The so-called machine vision is still at the stage of taking a photo at least five years ago and then fuzzy contrast recognition, let alone complex structure, let alone high precision...

Let's put it this way, it can only identify whether there are bubbles on the surface, whether there is a missing corner or something.

Of course, it is no problem to use it as tableware.

But it is obviously not possible to use it for high-precision multi-dimensional recognition.

Hearing the report of the two, Professor Tang who was at home was also a little stunned.

He was holding the bowl and the spoon, frowning for a long time.

"Meaning, the problem cannot be solved by updating the system, right?"

"No, he uses a monocular camera. Our solution is a binocular camera, and only a binocular camera can meet high precision." Yang Chaoxiong said and glanced at Ye Ming: "On the way back, Ye Ming mentioned a I think the solution is very good. Use the binocular camera to achieve spatial positioning, and then build a comparison model and appearance according to the algorithm, so that the error tolerance rate for the robotic arm and the assembly line is very high, even if there are errors in the position and distance of the product to be detected. impact detection."

"Well..." Professor Tang nodded: "Well, let's think about the plan first and see if we can make a design sketch tonight. It would be best if we can give the cost... I'll ask again."

Yang Chaoxiong yelled immediately after hearing this: "Teacher, how do you pay for this cost?"

"Ask Ye Ming, hasn't he built a robotic arm and a binocular camera himself?"

Ye Ming: "..."

After hanging up the call, Yang Chaoxiong looked back at Ye Ming: "You know?"

"I know shit, I bought my binocular camera from Taobao, two hundred yuan each, do you dare to use it?"

Yang Chaoxiong: "...What about the expensive ones?"

"There are tens of thousands of expensive ones, professional industrial cameras, do you want them?"

Yang Chaoxiong: "..."

The takeaway was delivered, and the two ate boiled fish with the air conditioner on.

At this time, Ye Ming suddenly remembered that Professor Tang seemed to be eating just now, as if he was still feeding the child with a spoon.

"Senior Brother, Teacher Tang is over forty this year, right?"

"Um, what's the matter?"

"Excellent." Ye Ming gave a thumbs up: "I saw him feeding someone just now, did he have a second child?"

When Yang Chaoxiong heard this, the expression on his face immediately became a little weird.

"What's wrong?"

"Don't you know about Old Tang's son?"

"What's the matter?" Ye Ming was at a loss.

Seeing that Ye Ming really didn't know, Yang Chaoxiong put down his chopsticks and let out a long sigh.

"Two years ago, Old Tang's son had just finished the college entrance examination, and then got into a car accident. He couldn't move from the neck down."

"After the college entrance examination, Old Tang should drive to pick up his son. But Old Tang was taking us at the time, so he let his son go home by himself, right? It turned out..."

"Anyway, whether it's the teacher's wife or his son, I feel a little bit blaming Old Tang."

"And his son did very well in the exam, the score came out to be more than 400 in the province... At least Hua Wu has it."

Ye Ming fell silent after listening.

Such misfortune happened to the people around him, and it made everyone feel bad.

But after a while, he immediately looked at Yang Chaoxiong: "What is the teacher's topic for next year?"

Brain computer + wheelchair, isn't it specially prepared for this kind of people who can't move below the neck?

Yang Chaoxiong smiled and nodded: "If my son is like this, I will also push a subject to my son... Fuck! Pooh! My son will be safe and sound!"

Ye Ming: "..."

"Okay, let's not talk about this anymore, eat fish and eat fish."

...

After dinner, the two chatted for a while, but they still couldn't sit still, so they opened their notebooks and started making plans.

Professor Tang is right, Ye Ming is really quick to do this, after all, he has experience and ready-made codes.

But the cost...Ye Ming really couldn't afford it.

Fortunately, Professor Tang did not force others to do so. When it was close to 11 o'clock, he called the two of them and asked them to go to the factory again tomorrow to find out all about the recognition accuracy and bring back some samples by the way.

It sounds like someone has confessed.
