Chapter 531 - Repair

"You? Where are you from?"

The maintenance worker who had argued with Chen Fei looked him up and down seriously, then looked at the others, and finally realized...

I don't know this person!

"I'm with Secretary Shen... Well, you know!"

Chen Fei blinked.

The other party then noticed Shen Fei standing next to him, and suddenly realized that it was the secretary next to the boss.

Don't take bean buns as dry food. The deputy general manager of the group company is also a member of the boss and can directly influence the senior management of the board of directors.

Several maintenance workers looked at each other and understood collectively.

"Then you try it!"

It may be possible to polish jade with the help of others' stones! !

"Hey, hey, don't mess around!"

Shen Fei was afraid that Chen Fei would "sacrifice" this large industrial special printer on the spot with lightning speed.

The meat buns in the dog's stomach can't be vomited out.

"Don't worry, use the conventional operation, it is guaranteed to be fixed."

Chen Fei broke off the bracelet on his left wrist ("universal data transceiver"), pulled out the data line terminal, found the data terminal of the printer, and pushed it up.

Port specifications do not match?

That does not exist!

Since it is called "universal", adaptive deformation is the most basic ability.

Adam: Connection completed, L991 high-precision molecular polymerization 3D printer found!

"'Adam', retrieve the sensor and analyze the error identification code!"

Chen Fei ordered the artificial intelligence AI.

Using the "universal data transceiver" is a routine operation, and unconventional is "sacrifice", a very thorough one.

Adam: The servo motor drive circuit has no response, the X-axis servo motor response delay exceeds the threshold, and the software fault cannot be eliminated.

The control system related functions of large industrial special printers have not been fully developed, especially the general circuit part, which only guarantees the most basic applications. The redundant functions are actually not used in normal use, and the manufacturer has not developed them all in vain.

When it comes to AI "Adam", the performance of all electronic components will be fully explored. With the help of Chen Fei's unlimited computing power, the secondary development was completed in an instant, integrating all the functions of the printer.

Unplugging the data cable, Chen Fei buckled the "bracelet" back on his wrist.

"The servo motor drive circuit is faulty. The circuit board needs to be removed. Everyone, multimeters are waiting."

He doesn't understand these things, but "Adam" understands them.

"Ah? Servo motor? Which part of the servo motor?"

The maintenance personnel were surprised. They didn't expect Chen Fei to confirm the fault location so quickly.

Before this, some maintenance personnel suspected that there was a problem with which servo motor part caused the entire printer to fail to operate normally, but they did not thoroughly investigate, resulting in inconsistent judgments, which led to a dispute.

The answer provided by Chen Fei confirmed one of the guesses, making this judgment prevail all of a sudden.

"The feeding servo motor and the X-axis servo motor seem to have some problems."

Chen Fei waited for these maintenance personnel to make a final decision. This large industrial special printer will definitely not escape being disemboweled today.

It's said to be just rubbing, ha, man!

"Tear it down, take it down and see!"

The maintenance personnel of the Northern Ordnance Industry Group were also very brave. They immediately started to work, and the electric screwdriver turned and began to remove the shell, and soon revealed the dense and complex structure inside.

The feeding servo motor was quickly found and disassembled. The two probes of the multimeter poked and poked at the circuit part.

Not to mention the results of the electrical parameter verification, just by visual inspection, it can be clearly seen that several integrated circuits were burned a little, and the adjacent capacitors were burst.

The problem of excessive wear of the X-axis servo motor and the lead screw transmission controller was also confirmed on the spot.

The wear problem is easy to solve, it is just a manual job, but the circuit failure lacks spare parts, especially those integrated circuits, some of which have special chips, and even the general parts that can be replaced cannot be found.

The problem was indeed found, but this printer is temporarily useless.

Just when the maintenance personnel were about to give up, Chen Fei spoke again.

"Why not use analog circuits instead?"

"Analog circuits? Do you mean single-chip microcomputers?"

Some maintenance personnel who know some advanced technology shook their heads again. Using software to solve hardware problems is indeed an idea, but the cost is high. Both hardware and software need to be redeveloped at the same time.

"No, just use the development board directly. If there is no PC, use it instead. Well, you can also dismantle a mobile phone."

Artificial intelligence AI "Adam" listed hundreds of solutions for Chen Fei. All he had to do was choose the one that saved the most effort.

Fortunately, the drive circuit of the servo motor is not complicated, especially when replacing part of the circuit. If Chen Fei was asked to work on the logic circuit of a general-purpose processor, it would really be a life-threatening situation.

"Yes, can I?"

The maintenance personnel looked at Chen Fei as if they were looking at an industry master.

"Immediately, right away!"

Chen Fei was still waiting to use the printer, and he didn't want to waste time.

This is called self-reliance.

A spare mobile phone was soon delivered to him.

It is not impossible to use the mobile phone as a single-chip microcomputer. After all, it has all three elements: computing unit, storage unit and control unit. As for whether the performance is wasted, let's not consider it for now.

Find a few plastic plates, cut them into small squares of the same size, and under the power of gold, lay copper wires, sprinkle tiny electronic components one by one, and the pins automatically merge with the copper wire ends, saving even soldering, and then cover them with thin shielding shells.

Five layers of PCB spacers are insulated with barley paper, and the cigarette box-sized circuit board is pieced together. The flying wires are directly connected to the servo motor circuit board, disconnecting and replacing the original fault area.

"Install it, and then turn it on and try it!"

Chen Fei handed over the handmade circuit.

Although it is a handmade product, the neat serpentine lines and pin fusion points on it are full of industrial regularity.

Industrial-grade superpowers are so terrifying.

The circuit design and drive system are the credit of "Adam". Chen Fei only needs to follow the circuit diagram in the naked eye, and the circuit and component layout will not be wrong.

Excessive wear of the X-axis servo motor and the lead screw drive controller is easier to solve. Just pick up some sesame-sized alloy from somewhere to fill it up. It is estimated that there will be no problem in continuous operation for one or two thousand hours.

Ding! ~

The L991 high-precision molecular polymerization 3D printer started successfully and passed the self-test verification.

"Come, print some test things."

Chen Fei broke off the "universal data transceiver" on his left wrist again.

This time, no one had any objections.

Forget it, I won't rub it, and I inserted it openly.

The large-scale industrial special printer quickly started to work. Hundreds of large and small parts gradually took shape, and new parts continued to appear, filling the entire working space little by little.

The layout of the printed workpiece is not flat, but three-dimensional. After being hardened and shaped by the special band of blue light, it is refined by the laser beam to improve the precision and meet the tolerance range. The final product is obtained from the outlet.

In the name of testing, Chen Fei printed continuously for more than two hours, and someone helped to manually check the tolerance. The number of finished parts obtained was more than twice the original plan. Good people are rewarded, and it is definitely profitable.

Vice President Shen heard that one of the two industrial printers was broken, and heard that his daughter and Xiao Chen were also here, so he took a break to check. As a result, he saw Chen Fei standing in front of the broken printer, and several maintenance personnel in work clothes stood behind him, watching with serious faces.

The printer is broken, what are you tinkering with!

Shen Songling asked curiously: "Xiao Chen, what are you doing?"

Looking to the side, the number of printed finished products, regardless of variety, is at least tens of thousands.

"Parts of Jingneng Jet!"

Chen Fei told the truth. It is not easy to fool the future father-in-law. After all, he eats this business. Even if he gets away with it now, he will react sooner or later. If he leaves a bad impression, it will be bad.

The scope of the crystal jet that was tinkering with at the 911 Air Force Base that can be further modified is getting smaller and smaller. It may not be that the design is close to the final form, but it may be that his ability to continue to adjust with "Adam" has reached its limit.

Most of the progress so far has basically been made by crashing. The accumulated technology and experience are quite hardcore, but Chen Fei and "Adam" are not professionals in aircraft design, so it is not surprising that they hit the ceiling early.

"Huh?"

Shen Songling's eyes widened for a moment, but he quickly returned to normal.

If Chen Fei stole the design of "Cesosaur" from somewhere, he would be willing to believe it.

But the crystal jet?

Forget it!

No one will steal the design of the crystal jet. The key is not how to design and manufacture it, but whether there is an air knight, which is the most important thing.

For the sake of his daughter, Vice President Shen is reluctant to discourage the enthusiasm of young people. He patted Chen Fei on the shoulder with an appreciative attitude.

"Well, you are ambitious, work hard."

Old Shen doesn't believe him at all.

You have to become an air knight first!

But you can't become a sky knight just by relying on supernatural powers.
