[0022] The loading and unloading unit 4 includes a first electric push rod 41, a positioning groove 42 and a lifting seat 43. The first electric push rod 41 is installed at the inner bottom of the frame 1. The lifting seat 43 is fixed to the telescopic end of the first electric push rod 41. The positioning grooves 42 are evenly arranged on the lifting seat 43. The first electric push rod 41 is electrically connected to the PLC controller 7. The metal parts are placed in the positioning groove 42 of the lifting seat 43. The telescopic end of the first electric push rod 41 drives the lifting seat 43 to perform lifting and lowering movements, thereby transporting the metal parts between the fixed fixture 2 and the movable fixture 6, thereby facilitating subsequent fixing operations, which avoids the trouble of workers lifting metal parts to fix them, saving time and effort.

[0023] The drive mechanism 3 includes a second electric push rod 31 and a connecting seat 32. The second electric push rod 31 is installed on the side of the frame 1, and the connecting seat 32 is installed on the telescopic end of the second electric push rod 31. The second electric push rod 31 is electrically connected to the PLC controller 7. The drive mechanism 3 also includes a transmission shaft 33, a slide bar 34 and a sleeve 35. The sleeve 35 is fixed on the frame 1, and the slide bar 34 is fixed to the side of the transmission shaft 33. The transmission shaft 33 is slidably connected to the sleeve 35 through the slide bar 34. One end of the transmission shaft 33 is fixedly connected to the connecting seat 32. The drive mechanism 3 also includes a rotary joint 36. The other end of the transmission shaft 33 is rotatably connected to the movable clamp 6 through the rotary joint 36.

Then, the telescopic end of the second electric push rod 31 drives the transmission shaft 33 to move through the connecting seat 32, and the transmission shaft 33 slides relative to the shaft sleeve 35 through the slide bar 34. The end of the transmission shaft 33 drives the movable fixture 6 to approach the fixed fixture 2, thereby clamping and fixing the metal part. Then, the loading and unloading unit 4 returns to its original position. After the plating on one side of the metal part is completed, the output shaft of the servo motor 51 drives the active bevel gear 52 to rotate, and the active bevel gear 52 is meshed with the driven bevel gear 53 for transmission. The driven bevel gear 53 drives the fixed fixture 2 to rotate through the rotating shaft 8, thereby flipping the metal part. At this time, the movable fixture 6 rotates relative to the end of the transmission shaft 33 through the rotary joint 36.
