Description

Technical Field

[0002] In the current design and manufacturing of the automotive industry, based on new requirements for efficiency, quality and cost, the integration of components such as headlights, daytime running lights, front bumpers, grilles, radiators, etc. in the front area is becoming increasingly higher. In this case, front-end modular design came into being. Integrated subassembly effectively improves the efficiency of line assembly, shortens the size chain between matching components, reduces the tolerance accumulation, reduces component requirements, and effectively ensures the appearance matching quality. But at the same time, along with integration, the assembly requirements for integrated modules also increase simultaneously, with controllable costs, high efficiency and high quality.

[0003] At present, the industry basically uses relatively large auxiliary robotic arms for positioning and assembly. Large tooling has problems such as low assembly stability and difficulty in operation, which directly affects the final front-end matching quality and the efficiency of line operation; some adopt the method of splitting the front-end module into two upper and lower bodies, which are positioned and assembled separately. This method not only increases the development cost of parts, but also adds additional equipment and efficiency costs to line planning. Some also use the method of welding or screwing brackets in the welding body line. This solution causes deformation of the white body after high-temperature electrophoresis painting, resulting in changes in the bracket relative to the fender in multiple directions, and unstable positioning.
