[0023] By using the movable welding assembly and the transverse movable slide 3 in conjunction with each other, welding processing can be performed on different positions on the surface of the circuit board during the welding process. Specifically, the user can clamp and fix the circuit board to be welded through the clamping assembly, and then drive the circuit board to move transversely through the transverse movable slide 3. The longitudinal movable slide 6 will drive the welding head 9 to move longitudinally through the connecting plate 7. Through the setting of the electric telescopic rod 8, the welding head 9 can be driven to move up and down to perform spot welding on the circuit board.

[0024] Preferably, the above-mentioned clamping assembly includes a fixing plate 13 fixedly installed on the upper and lower ends of both sides of the inner cavity of the positioning frame 5, two groups of clamping plates 14 are provided on the inner sides of the two groups of fixing plates 13, and an oblique cut 15 is opened at one end of the two groups of clamping plates 14.
