"Operator No. 2 please pay attention! Turn the air flow butterfly valve to the automatic control state!"
"Operator #1 switched the suspension system to automatic state!"
"..."
At this time, Zheng Cheng took the walkie-talkie and gave instructions to the operators of the automatic painting and baking production line.
This production line has only six operators in a shift.One operator is responsible for managing the control room, and the other five operators are loading and unloading the suspension system.
As for the positions of feeding and unloading, they are usually completed by auxiliary workers and do not require professional skills.In some units, the operators of such positions are generally held by temporary workers.
Calculated in this way, the automatic spray paint and baking paint production line developed by Yiming Company only needs one operator per shift.The degree of automation is a rare level in China and can be said to be the most advanced.
Regarding this, Xu Zhenming is still a little conceited, thinking that it is no longer possible to reduce the number of operators.A production line cannot be designed to be unattended, right?
Looking at the busy workers and technicians in the project team, he started to inspect the source of the production line.
The first thing I saw was the outdoor fan system.
The fan system adopts frequency conversion motor and soft start.The position of the air inlet is designed with a three-pass filter system with three-stage filtration processes such as air filter element coarse filtration, oil and gas separation filtration and activated carbon adsorption filtration.
Nowadays, polymer filter membranes are not popular yet, and the cost is very high. Xu Zhenming suggested that Zheng Cheng adopt a three-stage filtration method.
This air filtration method is mainly to obtain pure air, which is very important for subsequent production.It will directly affect the product quality of spray paint and baking paint.
At first, everyone was arguing about this craft.Finally, Xu Zhenming made a final decision and chose this three-stage filtration process with relatively high construction cost.
The filtered compressed air is first stored in the air storage bag.At this place of the air storage bag, the compressed air begins to diverge, all the way to the automatic paint spraying room, and all the way to the air preheating room.The function of the air storage bag is mainly to maintain the air pressure in the pipeline, so that the air flows along the shunt pipeline toward the preheating room and the automatic paint spraying room.
These two are implemented in the production workshop, Xu Zhenming also came to the indoor inspection.
At this time, the suspension system has started to work, and the operator hoisted the workpiece on the hook.The suspension system carries the workpiece into the automatic painting booth.
In the center of the automatic spray booth is a suspension system, which carries the workpiece through the middle.The two ends are flexible doors, which can be closed at any time according to process needs to seal the automatic paint spraying room.
At this time, six painting robots installed on both sides of the suspension system are swinging and spraying paint on the workpiece.Above the automatic painting booth, there is an air pipe spraying air into the painting booth, flushing the suspended paint particles to the bottom of the room.
At the bottom of the automatic spray booth, there are rows of pipes.These pipes are drawing air, drawing air containing paint and thinner into the pipes.
Another outdoor fan unit is providing negative pressure to draw the air containing the paint mixture into the air purifier for purification.
This craft comes from later generations and should be the most advanced concept at the moment!
Before Xu Zhenming's rebirth, China was vigorously focusing on environmental protection issues and shut down many automatic painting lines.Like Yiming's circulating automatic painting line with air purifier, it is a new technology developed for environmental protection inspections.
He did it in one step and applied the new technology and new concept to the automatic spray paint and baking paint production line of Yiming Company, so as to avoid trouble later.
At this time, some of the workers involved in the commissioning have completed their work, lying in the plexiglass window of the automatic painting booth, watching the action of the automatic painting robot.
"My dear, this spray paint is very fast, faster than twelve painters spraying at the same time!"
"Do you know this is called an automatic painting robot? Of course robots are much faster than manual painting!"
"Our company uses robots to spray paint. Only one of our companies in the whole country has the ability to do so, right?"
The workers did not know the status of the industry and were talking about it.
Xu Zhenming is also watching the effect of automatic painting.When he saw that there was a problem with the paint film thickness of the workpiece and the coloration was a little light, he frowned slightly and turned his face to look at the technician in charge of debugging.
He hadn't spoken yet. A painter who came to assist in the debugging spoke, "Gong Zhang! There is a problem with the painting effect of these six painting robots, and the paint film thickness is definitely not enough!"
The painter is very experienced and can see the surface quality after painting.
The technician Xiao Zhang heard this and glanced at Xu Zhenming, who was standing nearby.
Xu Zhenming nodded at him, and said nothing.At this kind of moment, especially during the debugging phase of the production line, he doesn't want to point fingers and interfere with the work and thinking of the technicians.
After seeing this scene, Xiao Zhang hurriedly shouted to the walkie-talkie in his hand: "Central control room, central control room! The thickness of the paint film is not enough, we should deal with this immediately!"
He did not dare to say in front of Xu Zhenming: The big boss is also on the scene, so be careful.Even so, he emphasized his tone to remind Zheng Cheng in the control room.
On the other side of the intercom call, Zheng Cheng frowned and asked Wang Zhizhong, who was standing next to him: "Wang Gong! The feedback from the automatic spray booth: The paint film thickness is not enough, what should I do?"
Wang Zhizhong looked at the computer screen and pointed to the red dot on the control flow chart of the production line and said: "The workpiece has just left the automatic painting room, but has not entered the automatic painting room. We can reverse the production line, move back a bit, and paint again! "
The automatic control system designed by Xu Zhenming is very convenient, and the operating position of the workpiece can be displayed on the computer screen at any time.Regarding this point, there is no similar production line in China that can do it.
Not only that, he also designed a monitoring system to display the live images in the central control room through closed-circuit television.Due to the limitation of the level of science and technology, almost all current surveillance systems adopt the form of closed-circuit television, using analog signals.Even so, the concept of this real-time monitoring system that displays the production line site is relatively advanced.
According to Wang Zhizhong's instructions, the main operator in charge of operating the computer presses the alarm button to start inverting the suspension system and let the automatic painting robot paint the workpiece again.At the same time, he opened the adjustment interface of the PID control system and re-adjusted the parameters of the automatic painting robot and the traveling parameters of the suspension system.
Inadvertently, he saw Xu Zhenming from the monitor screen, so he pointed to the TV screen and shouted: "Minister Zheng, Wang Gong! Mr. Xu happened to be visiting the automatic spray booth!"
He was a little nervous, for fear that his boss Xu Zhenming would point out his operation mistakes.
Looking at his appearance, Zheng Cheng smiled and said, “It’s okay! I’ve seen Mr. Xu inspecting! We are debugging equipment. It is normal to make small mistakes. Mr. Xu said: Allow us to make mistakes. But you must be able to solve the problem yourself!"
While speaking, he still admired Xu Zhenming deep in his heart.Allow your own company’s employees to make mistakes. How many bosses in society can do it?
Before long, the painted workpiece enters the automatic paint booth.Zheng Cheng also saw Xu Zhenming walking forward along with the workpiece from the monitored TV screen.This time, he deliberately reduced the walking speed of the suspension system a lot, so that the workpiece on the suspension system can be sufficiently heated in the paint booth.
The principle of automatic paint baking is to use pure hot air to heat the workpiece and dry the paint on the workpiece to adhere to the surface of the workpiece.The hot air is heated by the air heating device, sprayed from the top of the spray booth, flows to the bottom, and then drawn out of the automatic paint booth by the negative pressure pipe.
After this process, there is no smell of paint or thinner in the workshop.It can be seen that the air duct system designed by Zheng Cheng is very successful, and the technical parameters meet the technological requirements proposed by Xu Zhenming.
Standing in front of the plexiglass window of the automatic paint booth and watching the workpiece for a while, Xu Zhenming walked with the workpiece and the suspension system to the end of the entire production line.
Here, three operators are busy: one operator is responsible for hoisting the workpiece, and the other two operators are responsible for packing the baked workpiece and preparing to send it to the manufacturing base.
"The automated production line is labor-saving and fast! The paint has dried in a few minutes!"
"That is! Our line uses robots to work, and the sixty people in our six-person spray painting workshop are not only working!"
"I heard that this speed is relatively slow. Once the suspension system speeds up, the three of us will be too late!"
The three operators were working while talking in a low voice.
At this time, technicians in the quality inspection department are inspecting the paint film thickness and surface quality of the workpiece.So far, except for the thicker paint film of several reworked workpieces, other workpieces meet the technical requirements.
After filling in the inspection data, the technician smiled knowingly at Xu Zhenming who was walking.
"Mr. Xu! The technical parameters of automatic painting and baking paint meet the technical requirements, and the thickness of the paint film is within the tolerance range. The spraying is very uniform, and the color of the image detected by the 100-knife is very stable!" He pointed to the table in his hand to report to Xu Zhenming test result.
At this point, the inspection of the entire production line is over.Xu Zhenming didn't say much, just smiled and nodded at the quality inspector.Immediately, he walked out the door of this workshop with a smile on his face.
Up to now, the research and development work of Yiming's automatic painting and baking paint production line has come to an end.What's more, this production line was completely made by Chinese people, and was successfully developed by a group of non-professionals from Yiming Company.
The intellectual property rights of this technology belong to Yiming Company. You can copy the production line at will, either use it yourself or sell it to customers in need, without having to look at others' faces!
Back in the office, Xu Zhenming took out a black notebook and crossed off the task of the automatic spray paint and baking paint production line.Immediately, he advanced the R&D project of the rectangular tube automatic drilling and blanking production line, and prepared to let Zheng Cheng's team and Hong Aiguo's team work together to tackle this project.
In this way, the technical team needs to make adjustments and re-division of labor.
"Operator No. 2 please pay attention! Turn the air flow butterfly valve to the automatic control state!"
"Operator #1 switched the suspension system to automatic state!"
