Induction welding production line of power module

Abstract

The invention discloses an induction welding production line of a power module. According to the induction welding production line of the power module, a transverse guide frame is arranged and provided with a first material taking assembly and a second material taking assembly, and the first material taking assembly and the second material taking assembly take materials from a shell and a cover plate correspondingly and move on the transverse guide frame in a reciprocating mode, namely main movement of the first material taking assembly and the second material taking assembly is horizontal movement, and the first material taking assembly and the second material taking assembly move in sequence, namely the first material taking assembly for performing material taking and placing to the shell arrives at a material conveying assembly on a vertical guide frame earlier than the second material taking assembly for performing material taking and placing to the cover plate; and in this way, the shell and the corresponding matched cover plate can be placed in the material conveying assembly arranged in a lifting mode in order, and due to the fact that the moving sequence is different, disorder and congestion of material taking can be avoided.

Description

technical field [0001] The invention relates to the technical field of power module production, in particular to an induction welding production line for power modules. Background technique [0002] Low-power power supply modules are usually composed of a copper shell and a bottom cover. The copper shell is filled with a module power supply part through heat-conducting glue, and the bottom cover is a printed circuit board that matches the module power supply part. Solder paste is applied. During the production process, the copper shell and the solder paste at the position of the copper-coated window of the printed circuit board need to be welded together. [0003] At present, the welding production of low-power power modules is mostly realized by electromagnetic induction welding. Before welding, the copper shell and bottom cover plate need to be placed on the corresponding jig, and the electromagnetic induction welding is realized by using the energized induction coil.

Problems solved by technology

Although there are similar feeding mechanisms such as vibrating trays in the prior art, these existing devices cannot meet the sequential feeding and placement of copper shells and bottom cover plates.

Although the multi-degree-of-freedom manipulator can also realize the feeding of the copper shell and the bottom cover, the multi-degree-of-freedom movement of the multi-degree-of-freedom manipulator leads to a more sophisticated and complex control system, and the multi-dimensional movement of the multi-degree-of-freedom manipulator also directly leads to The feeding path is longer and the feeding time is longer
