Description

Technical Field

[0001] This invention relates to the field of automotive headlight trim assembly technology, and in particular to an automatic trim positioning device. Background Technology

[0002] In existing technology, chrome-plated trim strips are fastened to the lamp body, with the silver chrome-plated portion at the front of the strip fitting snugly against the edge of the hood. This process requires high precision control, with errors within ±0.5mm. Precise positioning must be completed before fastening. However, the lamp body lacks a structure for precise trim strip positioning, only providing fastening holes. Therefore, the assembly accuracy of the trim strip and lamp body depends on whether the positioning structure on the fixture meets the precision requirements. Currently, during trim strip assembly, the lamp body is typically fixed in the fixture first, then the trim strip is placed on the lamp body for rough positioning, roughly aligning the trim strip holes with the pre-drilled fastening holes on the lamp body. After positioning, it is fastened with screws. This manual assembly method results in poor precision and consistency, low assembly efficiency, and cannot meet production requirements.
