Description

Technical Field

As competition in the automotive industry accelerates, companies are constantly developing new models and new structures to meet market demand, and different types of anti-collision beam assemblies have emerged. The anti-collision beam structure mainly includes a crossbeam body, an energy absorption box, a support block, and other ancillary accessories, including accessories connected to the vehicle body. When assembling such accessories, the accuracy of the relative position of the accessories in the anti-collision beam sub-assembly must be ensured. There are also various forms of connection between the accessories and the anti-collision beam sub-assembly, including bolt assembly, blind rivet assembly, and other forms. After assembly, the anti-collision beam assembly must also be laser marked to ensure that the relevant information of the anti-collision beam assembly product can be traced later.

[0003] In the existing technology, the assembly process of the automobile anti-collision beam sub-assembly is to manually assemble the parts, inspect them, and move the qualified products to the marking platform for laser marking. The required process is cumbersome and time-consuming. There is no special device for fixing the anti-collision beam sub-assembly in manual assembly, and the accuracy of the position of the parts on the anti-collision beam sub-assembly cannot be guaranteed. For the anti-collision beam assembly with complex structure, the bolts for fixing the parts are of different types and when the number is large, manual assembly is prone to misassembly, missing assembly, etc. In severe cases, it will also affect the subsequent installation of the anti-collision beam assembly and the vehicle body structure, and the consistency of the marking position cannot be guaranteed. Therefore, it is necessary to develop a special equipment that integrates assembly, inspection, and laser marking of the anti-collision beam sub-assembly and accessories to make up for the current shortage of technology.
