Problems solved by technology

Its disadvantage is that the two-dimensional scanning of the laser beam cannot weld plastic parts with complex shapes at all. The reason is that only two-dimensional scanning cannot ensure that the welding laser beam is focused on the surface of the welded workpiece.

Abstract

The multidimensional plastic welding laser device includes welding laser source, X- and Y-guide rails, work bench, fiber angle control console, Z-lead screw connected with X-guide rails, fiber angle controller connected to the Z-lead screw with fiber output head, three motors for the welding shifts of the fiber output head in X, Y and Z directions separately, one fourth motor to drive the fiber output head to swing for deflection output in welding inside Z-X plane, one fifth motor to drive the gear turntable to rotate in X-Y plane for the fiber output head to deflect to required position in welding. The present invention makes it possible for the fiber axis to be always perpendicular to the surface of the work piece, for the laser outputting lens to focus laser beam onto the surface of the work piece, and for the fiber output head to perform six-dimensional motion and to be always in the Z-plane.

Description

technical field [0001] The invention relates to a laser welding device, in particular to a multi-dimensional laser welding plastic device, which belongs to the technical field of laser processing. technical background [0002] With the development of my country's industrial economy, plastic materials are widely used in many fields, especially home appliances, automobiles, computers, communications, medical care, aerospace, etc., and many traditional metal parts (automobile intake pipes, fuel tanks, filters, medical The used fluid conveying systems, etc.) are gradually being replaced by plastics. The plastic materials used in these fields not only require a large quantity, but also have a variety of uses and high technological content. It is the best way to obtain high economic benefits in the plastic product processing industry. field. Therefore, people desire a faster, more effective and cleaner plastic welding method in the processing of plastic products. Due to the advanc...
