Description

Technical Field

[0002] The headlight structure is a tool for lighting the road when the vehicle is driving at night, and it is also a tool for issuing various vehicle driving signals. The headlight structure needs to be assisted by laser welding equipment during manufacturing. Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The heat on the laser welding surface diffuses to the inside through heat conduction. By controlling the width, energy, peak power, and repetition frequency of the laser pulse, the headlight structure to be welded is melted to form a specific molten pool for fusion welding.

[0003] In the prior art, the manufacturing and welding of the headlight structure requires stable clamping and diagonal adjustment through external equipment, so that the headlight structure clamping tooling needs to be adjusted and disassembled during each welding process, which is not conducive to the continuous welding of the headlight structure, and the headlight structure cannot be accurately adjusted diagonally, and the diagonal angle cannot be easily changed, so that each welding position needs to be provided with corresponding tooling for clamping, and the manufacturing and welding of the headlight structure cannot be tested in time, which makes it difficult to discover hidden dangers in the welding position in time, which easily leads to a defective rate.
