Adjustment & Polishing Line

The main job on the adjustment line is the installation of four-door and two-cover (vehicle doors, engine cover, trunk cover). It adopts wide plate chain, the workers can synchronously move between the wide plate chain and vehicle, so as to reduce the labor force.

The welding adjustment line is the last process before the complete body-in-white vehicle rolls off the assembly line, and it is an important link to ensure the clearance, surface difference, step difference accuracy and assembly consistency of each assembly part of the body-in-white. Its process equipment mainly includes assembly fixtures, assembly aids, inspection tools, tools and conveying systems. Among them, the tools are standardized tools, and the delivery system is a relatively fixed model, as long as it can meet the production program, its structure has a certain degree of versatility and a high degree of flexibility; only assembly fixtures and assembly accessories are used to ensure that the four doors and two covers are compatible with each other. The rigid connection of the body is used to control the gap, surface difference, step difference accuracy and assembly consistency between the body assembly and each connecting part. Therefore, the design concept, design basis, design structure, equipment debugging and application promotion of assembly fixtures and assembly aids will directly affect the assembly quality of the vehicle.

At the scene of the adjustment line of the mainstream automobile factory in China, we can see that the adjustment line of the welding workshop has always used ordinary simple equipment. Manually adjusting and repairing molds increases labor intensity, and the workload is large, which has a great impact on production tempo and cannot be used for long-term production. However, due to technical reasons, multi-shift rotation has been used to solve this problem before.

The production site of the automobile adjustment line rings the alley, and the emphasis is on the production rhythm and efficiency. How to create an efficient and labor-saving human-computer interaction booster is the theme of the complex equipment design of the Haitong production line. Kinte discussed in depth through on-site inspections and pre-staff , designing highly customized equipment and fully considering the adaptability of man-machine combination.

Kinte can increase the assembly accuracy and save time by changing the original assembly process, realizing automatic tightening, and improving the inconsistent consistency of the product after tightening. After verification and discussion, the combination of the human-computer interaction assisting equipment provided by Kinte and the complex tooling of the car body can achieve high-frequency precision operations with a production cycle of 57 seconds, fully reduce the labor intensity of workers, and achieve excellent consistency performance.
