In this embodiment, the first conveying component 111 and the second conveying component 112 have the same structure, and both the first conveying component 111 and the second conveying component 112 are prior arts. Specifically, they are a conveyor belt structure with a placement base structure, and the placement base is used for placing the inductor coil. During operation, the first conveying component 111 conveys the inductor coil from back to front. When the inductor coil is conveyed to the front end position of the first conveying component 111, the clamping component 12 clamps the inductor coil of the first conveying component 111 to the second conveying component 112, and then the second conveying component 112 conveys the inductor coil from right to left,Until the inductance coil is conveyed to the position of the lifting and feeding assembly 13, after being conveyed in place, the lifting and feeding assembly 13 clamps the inductance coil and rises to one end of the material-changing assembly 14.

After argon arc welding is completed, the workpiece is conveyed to the automatic screw locking device 7.

The first driving part 1541 and the second driving part 1542 are both double-axis cylinders. The two output ends of the first driving part 1541 are respectively connected to the opening and closing plates 153. The second driving part 1542 is installed on the first moving seat 156. The two output ends of the second driving part 1542 are respectively connected to the first sealed box 151 and the second sealed box 152. The third driving part 1543 is a motor, and the fourth driving part 1544 is a gripper cylinder. During material replacement, the first driving part 1541 drives the two opening and closing plates 153 to move away from each other, and the second driving part 1542 drives the first sealed box 151 and the second sealed box 152 to move away from each other, ensuring there is enough space for material replacement and preventing rigid collision between components. Then the material replacement assembly 14 clamps away the stripped paint inductance coil of the fourth driving part 1544 and rotates 180° for material replacement. After the material replacement is completed, the fourth driving part 1544 clamps the to-be-stripped paint inductance coil on the material replacement assembly 14 again. During laser paint stripping, the first driving part 1541 drives the opening and closing plates 153 to move closer to each other until they are combined, and the second driving part 1542 drives the first sealed box 151 and the second sealed box 152 to move closer to each other until they are combined, thus forming a relatively sealed space. Then the laser generator 155 performs laser paint stripping on the inductance coil through the clearance groove 1511 of the first sealed box 151, specifically on the four sides of the two pins of the inductance coil. When the laser paint stripping of the same side of the two pins is completed, the third driving part 1543 drives the fourth driving part 1544 to rotate 90°, and performs laser paint stripping on the next side of the two pins until the four sides of the pins are all completed with laser paint stripping. And during the rotation process, because the focus of the laser generator 155 remains unchanged while the height position of the pins changes, it is necessary for the fourth driving part and the fifth driving part to respectively drive the first moving seat 156 and the second moving seat 157 to move up and down synchronously for adjustment, so that the inductance coil, the first sealed box 151 and the second sealed box 152 move up and down synchronously. During the laser paint stripping process, air is blown into the sealed space through the air inlet pipe 158 and exhausted through the exhaust pipe 159, adopting an up-blowing and down-draining structure, so that the dust and debris generated by laser paint stripping are uniformly discharged, avoiding polluting the inductance coil, which is beneficial to improving the product quality. And through the first sealed box 151, the second sealed box 152, the opening and closing plates 153, the first driving part 1541 and the second driving part 1542, the laser paint stripping is carried out in a relatively sealed space, which can not only prevent external interference, but also prevent the dust and debris generated by paint stripping from flying and polluting the environment and the inductance coil, and cooperate with the first moving seat 156, the second moving seat 157, the fifth driving part and the sixth driving part to ensure the quality of laser paint stripping.,
