[0031] Specifically, when in use, the worker places the assembled metal fittings on the two clamping blocks 76, and then presses the metal fittings downward. The metal fittings squeeze the arc-shaped structure of the clamping blocks 76, so that the two clamping blocks 76 move away from each other, and the clamping blocks 76 drive the slider 77 to move. The slider 77 compresses the spring 79. When the metal fittings move to the bottom of the arc-shaped structure of the clamping blocks 76, the spring 79 pops open and resets to push the slider 77 to move. The slider 77 drives the clamping blocks 76 to reset, and the clamping blocks 76 clamp the metal fittings, and the belt body 101 of the metal fittings will The metal fittings are inserted into the groove 73, and then the chain conveyor 2 moves the bottom plate 71, thereby driving the metal fittings to move. The metal fittings move between the lower welding head 64 and the upper welding head 65. The adjusting cylinder 82 moves the extension plate 88 toward the direction close to the metal fittings through the slide plate 83. The extension plate 88 drives the pressing cylinder 89 and the second pneumatic clamp 86 to move. The second pneumatic clamp 86 clamps the support 103 through the clamp block 87 to prevent one end of the metal fitting from deviating. Then the pressing cylinder 89 moves the pressing block 810 downward, and the pressing block 810 pushes one end of the bending part 102 to be close to the belt The upper welding head 65 cooperates with the lower welding head 64 to weld the curved portion 102 and the belt body 101. The welded metal parts are continuously transported to the unloading mechanism 5 by the chain conveyor 2. The linear module 54 adjusts the position of the transverse plate 56 so that the first pneumatic clamp 57 is aligned with the metal parts. Then, the unloading cylinder 55 moves the first pneumatic clamp 57 and the unlocking piece 53 downward. The inclined surface 52 of the unlocking piece 53 first contacts the inclined block 75. The unlocking piece 53 squeezes the inclined block 75 so that the two inclined blocks 75 move away from each other. The inclined block 75 moves in the direction away from each other through the slider 77, and the clamping block 76 no longer clamps the metal fittings. Then the first pneumatic clamp 57 clamps the metal fittings. With the cooperation of the unloading cylinder 55, the first pneumatic clamp 57 moves the metal fittings upward. At this time, the unlocking piece 53 is still in contact with the inclined block 75, and the clamping block 76 does not clamp the metal fittings. Then, under the action of the linear module 54, the metal fittings move to the top of the guide hopper 3, and the metal fittings fall into the guide hopper 3. After being guided by the guide hopper 3, they move to the collecting box 4 for collection.
