"Mr. Xiong, this is the first workshop of the factory - the painting workshop. The goal is to paint the parts to prevent the car body from rusting and make the car body have a beautiful appearance!"
Thomas introduced to Xiong Huaizhi and others.
Liu Lang followed Xiong Huaizhi and saw a lot of car parts on the work platform in the workshop. Most of them were car shells, seats, steering wheels, etc. Many workers were wearing blue work clothes and had smiles on their faces.
The poisonous mask is worked meticulously with a special spray gun.
When Shanghai Volkswagen was first established, there was no such painting workshop, because painting is also a very technical job, especially coloring the car body shell, which requires skilled workers to spray the paint evenly.
All parts shipped from Germany had already completed the painting process. It was not until half a year later, when many employees gradually mastered the process after training, that Volkswagen built a painting workshop in China.
Of course, the paint used for painting still comes from Germany and cannot be produced domestically.
Thomas took everyone for a casual walk, and then came to the next workshop - the final assembly process
"This is the final assembly shop, which assembles the body, chassis, interior and other parts together to form a complete car!"
Thomas introduced.
"Final assembly workshop!"
Liu Lang watched carefully.
This assembly workshop is very large and is divided into several areas. Everyone is in the first area, the "cleaning area". They see various parts being placed on a special platform, and then the workers hold the spray heads suspended above.
Continuously spray and clean the parts in front of you, without leaving any corner. The various parts that have been processed are divided into categories and transported to the next area by different transportation methods...!
"Look at Germany. Every component is clean. Our country is still far behind!"
Although Dong Mingwu has watched it many times, he is very emotional every time he watches it.
In Liu Lang's eyes, this procedure was still very backward. After all, he came from more than thirty years later, when CNC automation had been fully adopted. There were probably not many people in the entire workshop, but the skilled skills of these workers made him secretly appreciate it.
nod.
Everyone did not stay in this area for long before they entered the next area, which is also the core area of the assembly workshop.
"This is the mandatory assembly line assembly area of our company... Most of them put the frame upside down on the assembly line first, install the front axle, rear axle and transmission shaft and other assemblies first, then flip the frame and assemble other assemblies and
Plans for parts.”
Thomas led everyone into a huge and spacious room and introduced it as he walked.
"Professor Xiong, this is the core area of Volkswagen. Compared with them, we are really far behind!"
Dong Mingwu whispered beside Xiong Huaizhi and Liu Lang.
Yes, in this workshop, the power of Western modern manufacturing is undoubtedly revealed.
This area adopts the catenary conveying method: the main components are transported to the assembly site and work station by conveyor chains, such as front axle conveyor chain, rear axle conveyor chain, engine conveyor chain, cab conveyor chain, and wheel conveyor chain.
The general assembly conveyor chain is composed of a bridge chain that is above the ground and a plate chain that is level with the ground. The conveyor chain is driven by a speed-regulating motor, and the speed is obtained by a reducer to obtain different speeds according to needs.
All the main parts of the car are transported by the conveyor chain. After being transported to the location, the shape of the car has basically appeared, and then six workers began to initially install the tires, driver's seat, front axle, rear axle, etc.
Hundreds of parts including the engine were fully connected within two hours.
In this way, when parts are transported to the assembly workshop, workers only need to assemble the vehicle on the plate chain at the work station, which greatly reduces the labor intensity of the workers.
After the workers are finished, the vehicle is already a semi-finished product, and this semi-finished product then enters the next area - the welding area.
Here, welders are welding each component separately, including the welding of the front and rear end parts of the body, the floor line, and the front and rear side panels of the body. The process takes about two hours.
After going through the above processes, the prototype of a finished vehicle has basically been born.
"Their level of automation is much better than forty years ago!"
Xiong Huaizhi stood aside and couldn't help but sigh.
"Liu Lang, when I went to school in Germany, workers were responsible for handling and fixing work. The whole workshop was noisy and accidents often happened. But now, the degree of automation in Germany has been very high, and the workers
The only things we do are welding, filling lubricants and oil, and some testing work. This efficiency is at least five or six times faster than in my time. Alas, look at us... what a gap!"
Xiong Huaizhi really has a lot of profiles. In the past forty years, the efficiency of Western countries has increased many times. Looking at China, it is basically the same as it was in the 1950s and 1960s. It still relies on a group of workers to work stupidly.
"Professor, back then our country put forward the slogan that more people are more powerful. In that era, more people were indeed more powerful. However, with the continuous advancement of modern industry, more people will greatly increase costs and reduce efficiency. An activity with the same workload will
, the Germans only need a dozen people to complete it, but in our country, more than a hundred people can't complete it!"
Liu Lang nodded and said softly, it only takes six or seven workers to assemble a car in this factory, and it only takes more than two hours to complete. However, if this work is done by domestic factories, it may take dozens of workers.
Individuals may not be able to do well at the end of the day. This is the gap.
As Liu Lang spoke, he strolled along the operation table. There were more than a dozen workstations in the workshop, and there was a car on each workbench. However, the work progress of each operation station was different. The fastest one
The car on the operating table is almost completed and is about to enter an area. The slowest one has just fixed the parts on the table. Several workers have not started to work yet, so these operating tables show all the processes.
Liu Lang wanted to write down all the details of their work.
Liu Lang walked slowly alone, and the others did not say anything. They didn't know what he was doing. Only Xiong Huaizhi and a few people from Huaxia University knew that Liu Lang had started to memorize again, although these procedures were nothing.
It is a core technology, but it is also a procedure of modern technology. It is also good to record it.
Thomas and the other Germans looked at Liu Lang in a daze. Who was this kid? He just strolled around casually and didn't care about the other party. Well, he didn't seem to be just strolling around casually. He seemed to be watching the workers at work very carefully.
"Kid, what are you doing?"
Thomas asked curiously with his translator.
"Nothing! I just want to learn your advanced German assembly technology!"
Liu Lang said casually in German.
"What? You speak German?"
Thomas was shocked that a seven or eight-year-old Chinese child could speak fluent German, which was beyond his expectations.
"You're busy with your business, don't worry about me, I'll be fine soon!"
Liu Lang's brain was running rapidly. The positions of various parts of the car, the techniques of the workers, and everything he could see were firmly remembered in his mind.
Ten minutes later, Liu Lang walked from one end of the operating table to the other, having completely mastered the entire process.
