Fully enclosed robot laser automatic welding machine for assembling automobile lamps

Abstract

The invention relates to a fully enclosed robot laser automatic welding machine for assembling automobile lamps. The fully enclosed robot laser automatic welding machine for assembling the automobile lamps comprises an enclosed body and a PLC safety control device arranged on the body, the body is provided with a closed door, a rotary workbench device is arranged in the body and comprises a rotatable workbench, a welding fixture is arranged on the workbench, a six-axis robot is installed on the side, located beside the workbench, in the body, a laser generator is installed at the welding working end of the six-axis robot, and the PLC safety control device is connected with the rotatable workbench device, the six-axis robot and the laser generator. A workpiece to be welded is clamped through the welding fixture, the movement of the six-axis robot is controlled through the PLC safety control device, the production tact is increased, and the production efficiency is improved simultaneously. The fully enclosed robot laser automatic welding machine for assembling the automobile lamps is suitable for welding machining of automobile lamp parts, good in flexibility, suitable for welding of complex curved surfaces, good in stability of welding quality and higher in product uniformity.

Description

technical field [0001] The invention relates to a fully enclosed robotic laser automatic welding machine for assembly of automobile lamps, which belongs to the technical field of automobile parts processing and production equipment. Background technique [0002] Automobile lights (headlights, taillights) are one of the most important parts of the appearance of the car. In recent years, the introduction of all-LED car light styles by major car light manufacturers (such as HELLA, AL, VALEO) has greatly affected the interior of the car lights. The design and assembly of parts put forward new high requirements. Under this condition, the traditional welding, processing and assembly technology of automobile lights can no longer meet the needs of this new design.

[0002] Automobile lights (headlights, taillights) are one of the most important parts of the appearance of the car. In recent years, the introduction of all-LED car light styles by major car light manufacturers (such as HELLA, AL, VALEO) has greatly affected the interior of the car lights. The design and assembly of parts put forward new high requirements. Under this condition, the traditional welding, processing and assembly technology of automobile lights can no longer meet the needs of this new design.

[0003] Since the inner parts of automobile lights are products with more complex surfaces, it is a better option to use laser welding technology to process inner parts such as new car lights. However, laser welding requires precise robot processing and positioning technology. Foreign countries often adopt a strict technical blockade attitude towards such technologies, while domestic research on such cutting-edge technologies is relatively backward, making it difficult to guarantee the quality stability and consistency of welded parts
