Description

Positioning device for welding jig of rear car lamp hot plate Technical Field The application relates to the technical field of automobile lamp processing, in particular to a positioning device for a rear automobile lamp hot plate welding jig. Background In the published patent document with the publication number of CN114103130A, an automobile lamp welding mould is provided, which comprises an upper welding mould and a lower welding mould, and further comprises an upper hot plate mould arranged corresponding to the upper welding mould and a lower hot plate mould arranged corresponding to the lower welding mould, wherein the upper hot plate mould is positioned above the lower hot plate mould, the upper hot plate mould and the lower hot plate mould are movably arranged between the upper welding mould and the lower welding mould, a mask cavity for placing a car lamp mask is formed between the upper welding mould and the upper hot plate mould, and a lamp body cavity for placing a lamp body is formed between the lower welding mould and the lower hot plate mould. The parts are softened by the heating of the upper die and the lower die, and then the products completely conform to the upper die and the lower die through the positioning structure of the upper die and the lower die, so that the products are corrected, the welded products can meet the requirements of size and performance, and the product quality is improved. In actual use, after an operator is required to manually connect a product with the positioning structures of the upper die and the lower die, the positioning structures can enable the product to completely conform to the upper die and the lower die during operation, but errors exist in manual operation, the product cannot be adsorbed and positioned correctly, the positioning efficiency is low, and the positioning effect of the product is required to be improved.
