AI Technical Summary

Technical Problem

During the welding process of existing PCBA boards, the patch is easily displaced, causing welding position deviation, and the fixing parts cannot be adjusted according to the size of the PCBA board and patch, and cannot be effectively fixed.

Method used

A patch welding device for PCBA board is designed. By setting up four elastic card parts to fix the patch, combining the positioning card board and the positioning bolt to achieve stable fixation of the PCBA board, and the clasping and installation of the upper cover and the base is ensured that the patch corresponds to the position of the PCBA board.

Benefits of technology

The stable fixation of the patch and the accurate positioning of the PCBA board are achieved, which avoids the shift of the patch during welding, ensures the accuracy of the welding position, and thus improves the welding quality of the PCBA board.

Abstract

The utility model discloses a printed circuit board assembly (PCBA) patch welding device which comprises a base and an upper cover buckled above the base, fixing frames are fixed on the outer walls of the two sides of the top of the base through bolts, a notch is formed in the outer wall of one side of the base, and a supporting table is fixedly installed in the center of the inner wall of the bottom of the base. A positioning piece is arranged on the outer wall of one side of the top of the base, a lead screw is inserted into a center hole in the top of the upper cover in a threaded mode, a pressing plate is rotationally installed at the bottom end of the lead screw, an elastic clamping piece is arranged on the outer wall of the bottom of the pressing plate, and a handle is welded to the outer wall of the top end of the lead screw. According to the utility model, through the arrangement of the four elastic clamping pieces, the patch can be stably fixed below the pressing plate, the PCBA plate can be stably fixed above the supporting table through the positioning clamping plates and the positioning bolts, and through the buckling installation of the upper cover on the base, the position correspondence of the patch and the PCBA plate is realized. Therefore, the whole structure is placed in a high-temperature furnace to be welded.
