Auxiliary tool for tinning semiconductor element

The auxiliary tool comprises an auxiliary table, a vertical frame is arranged at one end of the table top of the auxiliary table, a supporting plate is horizontally arranged on the side face of the vertical frame, a clamping mechanism used for positioning the semiconductor element is arranged under the supporting plate, and the clamping mechanism is used for clamping the semiconductor element. Therotating wheel is rotated to enable the second bevel gear and the first bevel gear to be in meshing transmission, so that the first screw rod drives the first nut seat to move in the vertical direction, the supporting plate moves in the vertical direction, the position of the clamping mechanism in the vertical direction is adjusted, the semiconductor element is fixed to the clamping mechanism, and after the semiconductor element is fixed, the first nut seat is driven to move in the vertical direction. In the machining process, an operator can rotate the rotary disc to rotate the semiconductorelement, the tinning angl
