[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-4As shown, an automatic sorting device for reduction gearboxes includes a worktable 1, a carrier 2 disposed on a rotating disk 11 on the worktable 1 for placing reduction gearboxes, a vision inspection mechanism 3, a belt conveyor 4, a good product clamping mechanism 5, a defective product guide plate 6, and a defective product clamping mechanism 7. The vision inspection mechanism 3, the good product clamping mechanism 5, and the defective product clamping mechanism 7 are arranged at intervals on the worktable 1. The vision inspection mechanism 3 is disposed on the worktable 1 and is used to inspect the reduction gearboxes on the carrier 2. The belt conveyor 4 is disposed on the worktable 1 and is used to transport reduction gearboxes that have been determined to be good products by the vision inspection mechanism 3. The defective product guide plate 6 is disposed on the worktable 1 and is used to guide the reduction gearboxes determined to be good products by the vision inspection mechanism 3. The defective gearbox is handled by a degraded gearbox. A defective product clamping mechanism 7 is mounted on the workbench 1 and used to transfer the defective product to the defective product guide plate 6. A good product clamping mechanism 5 includes a mechanism frame 51 mounted on the workbench 1, a horizontal slide plate 52, a first cylinder 53 mounted on the mechanism frame 51 for driving the horizontal slide plate 52 to move laterally, a vertical slide plate 54 slidably mounted on the horizontal slide plate 52, and a second cylinder 55 fixed to the horizontal slide plate 52 for driving the vertical slide plate 54 to reciprocate on the horizontal slide plate 52. The vertical slide plate 54 is equipped with pneumatic grippers 56 for gripping the degraded gearbox on the carrier. Driven by the first cylinder 53 and the second cylinder 55, the pneumatic grippers 56 transfer the good product to the belt conveyor line 4. This automatic gearbox sorting device automatically distinguishes between good and defective gearboxes using a visual inspection mechanism and instructs the subsequent good product clamping mechanism to automatically perform the sorting action without manual intervention, achieving full automation from inspection to sorting. The pneumatic gripper 56 has two symmetrically distributed grippers 561 for clamping the rotating shaft of the reduction gearbox. Each gripper 561 has two arc-shaped clamping grooves 562 that clamp onto both sides of the rotating shaft. The grippers contact the rotating shaft of the reduction gearbox through the arc-shaped clamping grooves, increasing the clamping contact area and ensuring that the grippers can reliably clamp the rotating shaft of the reduction gearbox.

[0021] like Figure 2As shown, the defective product clamping mechanism 7 includes a support frame 71 mounted on the worktable 1, a picking block 72 slidably mounted on the support frame 71, and a robotic arm 73 fixedly mounted on the picking block 72 for clamping defective products. A pneumatic drive mechanism 74 is mounted on the support frame 71, which drives the robotic arm 73 via the picking block 72. The robotic arm 73 has three gripping jaws 731 for clamping a reduction gearbox. The robotic arm clamps the reduction gearbox using the three gripping jaws, thus ensuring that the defective product clamping mechanism can reliably clamp the reduction gearbox. The pneumatic drive mechanism 74 includes a guide rail plate 741 fixed to a support frame 71, a first slide plate 742 slidably mounted laterally on the guide rail plate 741, and a second slide plate 743 slidably mounted longitudinally on the first slide plate 742. A material-grabbing block 72 is linked to the second slide plate 743. A third cylinder 744 is mounted on the guide rail plate 741 to drive the first slide plate 742 to reciprocate on the guide rail plate 741. A fourth cylinder 745 is mounted on the first slide plate 742 to drive the second slide plate 743 to reciprocate on the first slide plate 742. This pneumatic drive mechanism uses a dual-cylinder drive, which can reliably drive the robotic arm to grab and release defective products, thereby improving sorting efficiency.

[0022] like Figure 1 As shown, the visual inspection mechanism 3 includes a support plate 31 mounted on the workbench 1 and an industrial camera 32 mounted on the support plate 31. The industrial camera 32 is fixed to the support plate 31, and its lens is positioned facing the reduction gearbox on the carrier 2. The visual inspection mechanism uses the industrial camera to inspect the appearance of the reduction gearbox and whether any parts are missing. This visual inspection mechanism has the advantages of simple structure, low cost, and fast inspection speed. The defective product guide plate 6 is provided with a guide sloping chute 61, and the outlet of the guide sloping chute 61 is connected to the defective product collection box. A counting photoelectric sensor 62 for counting the defective products passing through is installed in the guide sloping chute 61. The independently designed defective product guide plate can separate and transport defective products from good products in real time, avoiding channel congestion and mutual interference, effectively improving sorting efficiency. The counting photoelectric sensor can count the number of defective products, which is conducive to realizing digital management. The belt conveyor line 4 includes a frame 41, a drive roller 42, and a driven roller 43 mounted on a workbench 1. The drive roller 42 and driven roller 43 are rotatably mounted at both ends of the frame 41. A motor 44 is mounted on the frame 41 to drive the drive roller 42. A belt 45 connects the drive roller 42 and the driven roller 43. A packaging station for packaging reduction gearboxes is located on the side of the workbench 1 corresponding to the drive roller 42. By setting up an independent belt conveyor line and a defective product guide plate, good products and defective products are separated and transported in real time, avoiding channel congestion and mutual interference, and further improving the overall sorting efficiency.

[0023] like Figure 2 and 4 As shown, the carrier 2 includes a carrier base 21 mounted on a rotating disk 11 and a carrier cover 22 detachably connected to the carrier base 21. A positioning space for placing a reduction gearbox is formed between the carrier cover 22 and the carrier base 21. A positioning protrusion 221 is provided on one side of the carrier cover 22, and a guide groove 211 is provided on the carrier base 21 to cooperate with the positioning protrusion 221. The positioning protrusion 221 passes through the guide groove 211. A bolt 23 is provided on the carrier cover 22, passing through the carrier cover 22 and threadedly connected to the carrier base 21. The carrier cover and carrier base are assembled by a snap-fit ​​method, and the carrier cover and carrier base are connected by bolts, which helps improve the assembly efficiency of the carrier and ensures that the carrier can reliably carry the reduction gearbox.

[0024] This automatic gearbox sorting device integrates visual recognition and automated handling, achieving intelligent, automated, and high-precision gearbox sorting operations. This effectively improves the production efficiency of gearboxes, ensures sorting quality, and reduces production costs.
