Reversible clamp for welding circuit board

Abstract

The invention relates to a reversible clamp for welding a circuit board. Two ends of the pedestal of the clamp symmetrically fix a bracket respectively, wherein a positioning column is fixed on one bracket; a PCB fixed pin clamp reverse handle, a lock position bolt and a rotary three-directional positioning plate are fixed on a PCB fixing frame respectively; both of the two ends of the PCB fixing frame are connected with the two brackets through a straight shaft respectively; a pressing plate supporting block is fixed on an end face of the PCB fixing frame; two pressing plate position-returning columns are fixed on the PCB fixing frame and the pressing plate supporting block respectively; one end of an IPM pressing plate is arranged on the pressing plate supporting block and fixedly connected with the PCB through a hinge; the other end of the IPM pressing plate fixes a lock position pin; and the lock position pin is in lock joint with the lock position bolt. The reversible clamp of the invention has the following advantages that: 1, the reversible clamp completely meets the technical requirements on a drawing, avoids difficulties of the subsequent assembly and better guarantees the quality of products; and 2, the reversible clamp manually welds on line, can optionally adjust the welding way, and completes on-line mobile welding of a plurality of rows of tube legs of an IPM so as to smoothly carry out the production, better control production speed and improve the production efficiency.

Description

technical field [0001] The invention relates to a fixture, in particular to a reversible fixture for circuit board welding. Background technique [0002] At present, the reverse side welding process of high-power components after wave soldering of PCB circuit boards is mostly manual welding by a single person after fixing. This method can perform manual welding more stably, but this method also has obvious disadvantages: Manual soldering requires constant adjustment of the PCB direction for multi-tube leg components. The operation is cumbersome, and the beat of each station in the overall production cannot be controlled. It cannot completely achieve a streamlined production method, which has hidden quality risks and low production efficiency. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides a circuit board welding device that can ensure that high-power components are close to the PCB surface, can completely ach...
