Plastic laser hybrid welding system

Abstract

The invention relates to the technical field of laser welding, in particular to a plastic laser hybrid welding system. The plastic laser hybrid welding system comprises a welder bracket, a welding robot and a laser emitter and further comprises a multi-color light source device, wherein a clamp for clamping a welded component is arranged on the welder bracket, the laser emitter comprises a laser head, and both the laser head and the multi-color light source device are mounted on the welding robot. The clamp is used for clamping the welded component, ensures that the welded component can be fully bonded, and ensures the connecting firmness, the water tightness and the air tightness of the welded component. Two kinds of light are emitted by the laser head and the multi-color light source device under the control of the welding robot to carry out hybrid welding, and the welded component is prevented from being burnt by a laser light beam in the direction of a light path. Meanwhile, thermal stress and vibration stress produced by the welded component are reduced, the deformation of the welded component is prevented, and the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a plastic laser composite welding system. Background technique [0002] With the development of science and technology, plastic laser welding technology has also developed rapidly in modern manufacturing. It mainly generates heat through the laser beam emitted by the laser, and the heat melts the welding area of ​​the welded parts and then glues them together. Compared with traditional manual welding, plastic laser welding technology has significant advantages. Its weld seam is firm and solid, with strong water tightness and air tightness. During the welding process, there is little debris and resin degradation that is generally not produced. , the machined surfaces of the parts can be tightly bonded together. In addition, the pollution to the welding environment is small, and many different types of materials can be welded. [0003] Existing plastic laser equipment, the ...

AI Technical Summary

Problems solved by technology

[0003] Existing plastic laser equipment, the control accuracy of the laser beam is not good, and the welding accuracy of the welded parts with complex shapes is low, which affects the connection firmness, water tightness and air tightness of the welded parts; secondly, the clamping of the welded parts is unreasonable , because the surface roughness of the welded parts is different, the molten rubber in the weld cannot be completely glued during the welding process, and the welding part of the product after welding will produce loose holes and other phenomena;

[0004] Furthermore, when the laser beam emitted by the laser head of the existing plastic laser equipment is used to weld the welded parts, due to the heat generated by the focus of the laser beam in the welding area to melt the wel...
