Laser synchronous welding device

Abstract

The invention provides a laser synchronous welding device which is used for welding an automobile lamp body and a lens. The laser synchronous welding device comprises a laser emitter, a first mold, a second mold and a light guiding pipe. The laser emitter is connected with an optical fiber set and meanwhile provides a plurality of beams of lasers. The first mold is used for containing the lamp body and suitable for moving up and down relative to the second mold. The second mold is used for containing the lens and evenly provided with a plurality of optical fiber fixing holes at the position corresponding to the welding position of the lens. Each optical fiber of the optical fiber set is connected to the corresponding optical fiber fixing hole. The light guiding pipe is used for shaping and focusing the lasers and located in the second mold. The light guiding pipe transversely penetrates the optical fiber fixing holes, and therefore the lasers can irradiate the light guiding pipe after being transmitted through the optical fibers. When the first mold moves to coincide with the second mold, the lasers shaped by the light guiding pipe penetrate the lens and are focused on welding ribs of the lamp body. The welding ribs of the lamp body are molten, and therefore the lamp body and the lens can be welded together. The device finishes welding the whole automobile lamp synchronously at a time and is high in efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of manufacturing automobile lamps, in particular to a laser synchronous welding equipment for welding lamp bodies and light distribution mirrors of automobile lamps. Background technique [0002] At present, friction welding and hot plate welding are generally used for welding automobile lights: [0003] Friction welding is that during welding, the rotating workpiece starts to rotate at a high speed under the drive of the motor, and the moving workpiece gradually moves closer to the rotating workpiece under the action of axial force. After the workpieces on both sides are contacted and pressed tightly, some asperities on the friction interface first stick Contact and shear, and generate frictional heat. As the actual contact area increases, the friction torque rises rapidly, and the temperature at the friction interface rises accordingly, and the friction interface is gradually covered by a layer of high-te...
