[0031] In this embodiment: the loading mechanism includes a slide rail 301 arranged at the bottom end of the support seat 100, a threaded rod 302 is rotatably installed in the slide rail 301, a moving seat 304 is slidably installed in the slide rail 301, the moving seat 304 is threadedly connected to the threaded rod 302, a moving motor 303 is installed at the rotating end of the threaded rod 302, a feeding sleeve 305 is fixed to the upper end of the moving seat 304, a plurality of top blocks 306 are slidably installed on the inner wall of the feeding sleeve 305, the rear end of the top block 306 is arc-shaped, a clamping spring is connected between the top block 306 and the feeding sleeve 305, and a feeding assembly for unloading the workpiece is provided on the front side of the slide rail 301.

[0033] Working principle: first, the workpiece to be welded is conveyed into the feeding sleeve 305, and the workpiece is pushed forward so that the front end of the workpiece presses against the multiple top blocks 306, driving the multiple top blocks 306 to clamp the workpiece, driving the moving motor 303 to drive the threaded rod 302 to rotate, and then driving the moving seat 304 to move forward, driving the workpiece clamped in the feeding sleeve 305 to move forward, and inserting the workpiece into the clamping fixture 203. The workpiece presses the button 219 in the clamping fixture 203, prompting the button 219 to control the multiple electric push rods 206 to drive the sliding ring 205 to move forward, and the sliding ring 205 squeezes the multiple clamping blocks 204, prompting the multiple clamping blocks 204 to firmly clamp and fix the workpieces of different diameters inside the clamping fixture 203.

[0034] Then, the moving motor 303 is driven to reverse and drive the feeding sleeve 305 to reset forward, and multiple clamping fixtures 203 are circulated and loaded in this way. The rotating motor 202 is then driven to drive the rotating disk 201 to rotate, and the clamped workpiece is rotated to the bottom of the welding gun 215. While the rotating disk 201 is constantly rotating, the workpiece is welded and the loading of other clamping fixtures 203 is achieved at the same time.

[0035] The lifting motor 209 is used to drive the lifting screw 210 to rotate, drive the lifting plate 211 to move up and down, drive the welding gun 215 to move up and down, and then use the adjusting motor 213 to drive the adjusting screw 214 to rotate, and then drive the welding gun 215 to move back and forth.

During welding, the dust suction fan 217 inside the dust suction box 216 is driven to rotate, and the dust suction pipe is used to adsorb the polluted gas generated during welding in the dust suction box 216. The activated carbon net 218 in the dust suction box 216 is used to purify the polluted gas to prevent the polluted gas from polluting the surrounding environment. The automated loading and unloading assembly method is used to speed up the loading and unloading time of the workpiece and improve the welding efficiency of the workpiece.

[0036] After welding the workpiece, when the workpiece rotates to the lower end of the rotating disk 201, the proximity switch 309 detects the position of the workpiece, thereby controlling the electric push rod 206 to drive the sliding ring 205 to reset and disengage from the squeezing of the multiple clamps 204, so that the multiple clamps 204 are released from the clamping and fixing of the workpiece, and then the workpiece falls onto the unloading table 307 and finally slides into the material boxes 308 on both sides for collection.
