The maintenance man who was choking with Chen Fei looked carefully up and down for a few times, then looked at the others, and finally came to his senses...
I don’t know this person!
"Secretary Shen and I...well, you know!"
Chen Fei blinked.
Only then did the other party notice Shen Fei standing next to him, and suddenly realized that she was the secretary next to the boss.
Don't use bean bags as dry food. The deputy general manager of the group company is also a big boss and can directly influence the top management of the board of directors.
Several maintenance personnel looked at each other and understood instantly.
"Then try it!"
Stones from other mountains can attack jade, maybe?!
"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 go into the dog's stomach and he can't spit them out.
"Don't worry, use normal operations to ensure it's repaired."
Chen Fei took off the wrist bracelet ("universal data transceiver") on his left wrist, pulled out the data cable terminal, found the data terminal of the printer, and dug into it.
Port specifications do not match?
That doesn't exist!
Since it is called "universal", adaptive deformation is the most basic ability.
Adam: After the connection is completed, I discovered the L991 high-precision molecular polymerization 3D printer!
"'Adam', retrieve the sensor and analyze the error identification code!"
Chen Fei gave orders to the artificial intelligence AI.
Using the "universal data transceiver" is a routine operation, and unconventional operation is a "sacrifice", which is very thorough.
Adam: The servo motor drive circuit is unresponsive, the response delay of the X-axis servo motor exceeds the threshold, and the software fault cannot be eliminated.
The relevant functions of the control system of large-scale industrial special printers have not been fully developed, especially the general circuit part, which only guarantees the most basic applications. In fact, the extra functions are not used in normal use, and the manufacturers have not developed them all in a superfluous manner.
When it comes to the artificial intelligence AI "Adam", the performance of all electronic components will be fully explored. With the help of Chen Fei's infinite computing power, the secondary development is completed in an instant, integrating all the functions of the printer.
Unplugging the data cable, Chen Fei buckled the "wrist bracelet" back on his wrist.
"The servo motor drive circuit is faulty. The circuit board needs to be disassembled. Everyone, use a multimeter to help."
He doesn't understand these things, but "Adam" understands and that's it.
"Ah? Servo motor? Which part of the servo motor?"
The maintenance staff were surprised. They did not expect Chen Fei to confirm the fault location so quickly.
Prior to this, some maintenance personnel suspected that there was a problem with the servo motor part, causing the entire printer to fail to operate normally. However, they did not thoroughly investigate, resulting in inconsistent judgments, and this led to a dispute.
The answer provided by Chen Fei confirmed one of the guesses, making this judgment suddenly gain the upper hand.
"There seems to be something wrong with the feeding servo motor and the X-axis servo motor."
Chen Fei waited for these maintenance personnel to finally make up their minds. This large industrial special printer would definitely be disemboweled today.
It was just a deal, hehe, man!
"Tear it apart, take it apart and take a look!"
The maintenance staff of the Northern Ordnance Industry Group were also very courageous. They immediately started to use the electric screwdriver and began to remove the shell. The dense and complex structure inside was soon revealed.
I quickly found the feeding servo motor, dismantled it completely, and poked at the circuit part with the two probes of the multimeter.
Not to mention the verification results of the electrical parameters, just by visual inspection, you can clearly see that several of the integrated circuits have been burned a little, and the adjacent capacitors have exploded.
The problem of excessive wear of the X-axis servo motor and screw drive controller was also confirmed on the spot.
The problem of wear and tear is easy to solve, it's just manual work, but there is a lack of spare parts for circuit failures, especially those few integrated circuits, which contain special chips, and there are no universal parts that can be replaced.
The problem was indeed found, but the printer is temporarily out of service.
Just when the maintenance staff were about to give up, Chen Fei spoke up again.
"How about using analog circuits instead?"
"Analog circuit? You mean microcontroller?"
Some maintenance personnel knew some advanced technology and shook their heads again. It is indeed an idea to use software to solve hardware problems, but the cost is high. Hardware and software must be developed simultaneously.
"No, just use the development board. If not, use a PC instead. Well, you can also disassemble a mobile phone."
The artificial intelligence AI "Adam" listed hundreds of solutions for Chen Fei, and all he had to do was choose the one with the least effort.
Fortunately, the drive circuit of the servo motor is not complicated, especially when replacing part of the circuit. If Chen Fei were to work on the logic circuit of a general-purpose processor, he would really die.
"Can, is it okay?"
The maintenance staff looked at Chen Fei as if they were looking at an industry master.
"immediately!"
Chen Fei was still waiting to use the printer and didn't want to waste his time.
This is called self-reliance.
A spare mobile phone was quickly delivered to him.
It is not impossible to use the "dimension reduction attack" of mobile phones as a single-chip microcomputer. After all, the three elements of computing unit, storage unit and control unit are readily available. As for whether the performance is wasted, we will not consider it for the time being.
I found a few plastic boards and cut them into small square pieces of the same size. Under the power of the metal system, I laid out copper wires and sprinkled small electronic components one by one. The pins automatically merged with the ends of the copper wires and soldered.
Save it all and cover it with thin shielding shells.
The five-layer PCB is separated by insulated highland barley paper, and the circuit board the size of a cigarette box is put together. The flying wires are run up and directly connected to the circuit board of the servo motor, disconnecting and replacing the original fault area.
"Put it in, 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 stitching points on it give it an industrial look.
This chapter is not over yet, please click on the next page to continue reading! Industrial-grade superpowers are so terrifying.
The circuit design and drive system are the work of "Adam". Chen Fei only needs to follow the circuit diagram visible to the naked eye, and the circuit and component layout will be correct.
Excessive wear of the X-axis servo motor and screw drive controller is easier to solve. Just pick some sesame-sized alloy from somewhere and patch 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.
"Here, print some test stuff."
Chen Fei took off the "universal data transceiver" on his left wrist again.
This time, no one had any objections.
Forget it, stop rubbing, and insert it openly.
The large-scale industrial special printer soon began to work whirringly. Hundreds of parts, large and small, were gradually formed, and new parts continued to appear, filling the entire working space bit by bit.
The layout of the printed workpiece is not flat, but three-dimensional. After being hardened and shaped by a special band of blue light, it is then refined by a laser beam to improve the precision and comply with the tolerance range. What is obtained from the output port is the final product.
In the name of testing, Chen Fei printed continuously for more than two hours at a stretch, and someone else helped manually check the tolerances. The number of finished parts he obtained was more than twice the original plan. Good people are rewarded, and they will definitely make money.
Vice President Shen heard that one of the two industrial printers was out of service, and heard that his daughter and Xiao Chen were here, so he took a moment to check, only to see Chen Fei standing in front of the malfunctioning printer.
, there were several maintenance personnel in work clothes standing behind, watching with serious faces.
Isn’t the printer broken? What are you trying to do?
Shen Songling asked curiously: "Xiao Chen, what are you doing?"
Looking further ahead, there are at least tens of thousands of printed products, regardless of variety.
"Crystal Jet Parts!"
Chen Fei told the truth that his future father-in-law should not be fooled casually. After all, he is in this line of work. Even if he is fooled now, he will react sooner or later. If it leaves a bad impression, that will be bad.
The scope of the crystal energy jet that he was tinkering with at the 911 Air Service Base was getting smaller and smaller. It was not necessarily because the design was nearing finalization, but it could also be that he and "Adam" had reached the limit of their ability to continue adjustments.
Most of the progress so far has basically been made by accident. The accumulated technology and experience are quite hard-core. However, neither Chen Fei nor "Adam" are professionals in aircraft design. It is not surprising that they hit the ceiling early.
.
"ha?"
Shen Songling's eyes widened for a moment, but he quickly returned to normal.
If Chen Fei didn't know where he stole the design of the "Mosasaurus", he would be willing to believe it.
But crystal jets?
forget it!
No one will steal the design of the crystalline jet. The key is not how to design and manufacture it, but whether there is an Aerial Knight. That is the most important thing.
For the sake of his daughter, Vice President Shen was reluctant to discourage young people, so he patted Chen Fei on the shoulder with an optimistic and appreciative attitude.
"Well, if you are ambitious, work hard."
Lao Shen didn't believe a word of his words.
