After searching: A circuit board clamping and welding platform with the authorization publication number CN219900575U, the circuit board clamping and welding platform includes a base frame, a rotating frame is arranged on the inner side of the base frame, both ends of the rotating frame are provided with raised shafts, and are movably connected to the base frame through the raised shafts; a rotating shaft is connected to the top of the rotating frame through a seat bearing, a sliding frame is welded on the top of the rotating shaft, and a sliding groove is provided on the sliding frame for facilitating the sliding connection of the bearing plate.

[0003] However, the above-mentioned circuit board welding platform still has some shortcomings. Since springs are used for clamping on the left and right sides, it is inconvenient to clamp and fix the circuit board left and right, front and back, which reduces the firmness of the circuit board clamping. In addition, springs are used for clamping, but the springs are prone to shaking, which further reduces the stability of the fixation, thereby reducing the quality of welding. In addition, a belt is used to drive the rotating shaft to rotate, and it is inconvenient to fix the rotating shaft after rotation. During welding, the load-bearing plate is prone to deflection, which reduces the welding quality. Therefore, we propose a circuit board welding platform to solve the above problems.
