An integrated circuit welding device according to claim 7, characterized in that: The control assembly comprises a limit block (4) fixedly mounted at a middle position of the top surface of the device body (1), telescopic rods (401) being fixedly connected to both sides of the limit block (4), a push block (402) being fixedly connected to the other end of the telescopic rod (401), and a hinge seat (403) being fixedly connected to the top position of the push block (402).

9. An integrated circuit welding device according to claim 8, characterized in that: A control panel (404) is rotatably connected to the hinged seat (403), and the other end of the control panel (404) is rotatably connected to a docking seat (405), and the docking seat (405) is fixedly connected to the bottom of the loading plate (305).

10. An integrated circuit welding method, based on an integrated circuit welding device according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: placing the flexible circuit board on the top plate (104), with side seats (105) fixedly connected to both sides of the top plate (104), and pressure rollers (106) rotatably connected to the side seats (105), wherein the pressure rollers (106) are attached to the surface of the flexible circuit board, and then placing one end of the flexible circuit board on a carrier plate (305), with a pair of positioning plates (307) fixedly connected to the carrier plate (305), and limiting the two sides of the flexible circuit board by the positioning plates (307); Step 2: Then, the telescopic rod (401) is extended and retracted through the control assembly to push the push block (402) to move. The movement of the push block (402) drives the control board (404) to move through the hinge seat (403). The other end of the control board (404) is rotatably connected to the docking seat (405), and the docking seat (405) is fixedly connected to the bottom position of the carrier plate (305). The movement of the push block (402) pushes the carrier plate (305) to move upward through the control board (404), so as to facilitate moving the flexible circuit board to the bottom of the welding assembly for welding. Step 3: During the final welding, the first motor (2) operates to rotate the transmission rod (201). The rotation of the transmission rod (201) drives the shaft pin (203) to move via the linkage plate (202). The movement of the shaft pin (203) facilitates the movement of the docking frame (204). The movement of the docking frame (204) drives the mounting plate (206) to move as a whole via the moving plate (205), so that the welding gun (209) performs welding work on the circuit on the flexible circuit board.
