[0025] In a further embodiment, Figure 1 As shown, in order to avoid collision between the workpieces 5 in the front and rear directions, a gap is set between two adjacent conveyor belts 2, and two rubber belts 4 are installed on each conveyor belt 2. The rubber belts 4 are attached to the edges of both sides of the outer surface of the conveyor belt 2. The workpiece 5 is located between the two rubber belts 4 in the conveyor belt 2. The workpiece 5 is transported by multiple unconnected conveyor belts 2, separated by twos, and there is no mutual interference during transportation. The transportation safety is better, and the rubber belts 4 prevent the workpiece 5 from shifting forward and backward and falling.

[0026] In a further embodiment, a processing tray 6 is installed on the metal processing table 1, and the processing of the workpiece 5 is performed on the processing tray 6, specifically, laser engraving is performed, and the workpiece 5 mainly includes a copper sleeve, which is transported to the processing tray 6, and laser engraving is performed to engrave symbols such as model and company. The processing tray 6 is connected to a moving mechanism for driving it to move in a direction parallel to the conveyor belt 2, and the moving mechanism includes a fixed rail 7, and the fixed rail 7 is provided with two, and the two fixed rails 7 are respectively installed at the front and rear sides of the upper end surface of the metal processing table 1, and the fixed rail 7 is slidably connected to the processing tray 6;

[0027] In order to fix the position of the workpiece 5 on the processing tray 6, a plurality of positioning rods 8 are installed on the processing tray 6. The positioning rods 8 are detachably installed on the processing tray 6 by bolts. The positioning rods 8 are plugged into the workpiece 5, and the center line of the positioning rods 8 is parallel to the center line of the conveyor belt 2.

[0028] In order to move the workpiece 5 to the processing tray 6 at intervals and perform laser engraving on the processing tray 6, a lifting mechanism is installed on the metal processing table 1. The lifting mechanism includes a lifting cylinder 9. The lifting cylinder 9 is installed on a cylinder bottom plate. The cylinder bottom plate is fixedly installed on the metal processing table 1. The output end of the lifting cylinder 9 is connected to a lifting plate 10. A clamping mechanism 11 corresponding to the conveyor belt 2 is installed on the lifting plate 10. The clamping mechanism 11 is used to clamp and release the workpiece 5.

[0029] Specifically, the clamping mechanism 11 includes a main rod 1101 and a clamping motor 1105. The main rod 1101 and the clamping motor 1105 are fixedly mounted on the lifting plate 10. A threaded structure is provided on the main rod 1101. The threaded structure is connected to the conical pressing sleeve 1102 by threads. A bevel is provided at the bottom of the conical pressing sleeve 1102. A thick gear 1103 is sleeved on the outer side of the conical pressing sleeve 1102.

The conical pressing sleeve 1102 is connected to the main rod 1101 by a thread. When the conical pressing sleeve 1102 moves downward, the bevel at its bottom will squeeze the inclined part, allowing the arc pressure plate 1106 to shrink inward to clamp the outer wall of the workpiece 5. At this time, the lifting mechanism can be cooperated with the moving mechanism at the bottom of the processing tray 6 to move the workpiece 5 to the positioning rod 8, or move it down from the positioning rod 8 to load and unload the workpiece 5. When the conical pressing sleeve 1102 moves upward, the arc pressure plate 1106 expands outward to loosen the middle workpiece 5. At this time, it can be used together with the moving mechanism and other components to place the workpiece 5 on the positioning rod 8 or put it back on the conveyor belt 2.
