Specifically, the lifting drive assembly includes a first cylinder 1, and the piston rod of the first cylinder 1 is connected to the lifting seat. A placing table 5 is arranged below the pressing block 2, and a positioning groove 4 is arranged on the placing table 5. The placing table 5 is rotatably arranged on the mounting seat 6. Furthermore, the mounting seat 6 is arranged on the first moving seat 7, and the first moving seat 7 is slidably arranged on the second moving seat 8 and locked by the first locking assembly. The second moving seat 8 is slidably arranged on the base and locked by the second locking assembly. The moving directions of the first and second moving seats are perpendicular to each other. The first and second locking assemblies are fasteners. By controlling the first and second moving seats to move, the front and back and left and right positions of the placing table 5 are adjusted. By controlling the placing table 5 to rotate, the angle of the placed reel shell can be adjusted, so that the positioning hole of the reel shell can be aligned with the pressing rod 3. It also includes a transfer seat 9, which is connected to the mobile drive assembly. Specifically, the mobile drive assembly includes a first motor, and the output end of the first motor is connected to the synchronous wheel. The synchronous belt 17 passes around the synchronous wheel, and the synchronous belt 17 is connected to the transfer seat 9. The mobile driving assembly can drive the transfer seat 9 to move to the top of the placement table 5 or the pin adding station. The transfer seat 9 is provided with a through pin groove 11. The transfer seat 9 is provided with an adsorption hole 18 aligned with the pin groove 11. The adsorption hole 18 is connected to the negative pressure assembly through a joint 10. The pressing block 2 is detachably provided with a pressing rod 3 that can extend into the pin groove 11. The pin adding station is provided with a vibration plate 16.
