[0040] In the embodiment, as Figure 1 shown, the workbench 2 is externally covered with a housing 1.

[0041] The working principle of the automatic sorting machine based on the embodiment is as follows: The materials are first conveyed to one side of the workbench 2 through the conveyor line 3. The conveyor line 3 includes a first conveying unit 31, which is liftably connected to the top conveying platform 325 of the cleaning unit 32 through a first lifting mechanism 311 at the bottom. The conveying direction of the top conveying platform 325 is towards one side of the workbench 2 and is used to convey the materials to be sorted onto the sorting platform 33. The materials enter the cleaning unit 32, and the air knife 324 above the top conveying platform 325 uses the airflow generated by the air source to clean the materials and conveys the materials to the sorting platform 33 through the top conveying platform 325.

[0042] The cleaned materials are conveyed to the sorting platform 33. The bottom of the sorting platform 33 is equipped with a second lifting mechanism 331, which can adjust the height as needed to connect with the top conveying platform 325 of the cleaning unit 32 for carrying the trays containing materials. On the sorting platform 33, the movable sorting unit 5 moves above the sorting platform 33 through the combined movement of the Y-axis 51 and the first X-axis 52, as well as the coordinated movement of the fifth lifting mechanism 531 and the U-axis 532. It uses the vision camera 534 and the light source to assist in identifying the materials. After marking the positions of the defective products, it precisely picks up the materials with the transfer head 533, puts the defective products into the defective platform 34, and the sorted good-quality materials are picked up by the transfer unit and continue to move backward along the conveying line 3, and finally are conveyed to the loading platform 4. The loading platform 4 includes a tray loading unit 41 and a tray unloading unit 42, which are respectively used for receiving and outputting the material Tray (such as a Tray). The material Tray enters the loading platform 4 from one side of the first tray loading module 411 of the tray loading unit 41, stays on the second tray loading module 412 after conveying, and the third lifting mechanism 413 drives the second tray loading module 412 to rise, thereby lifting the material Tray for the handling unit 6 to pick up and carry to the second tray unloading module 422 of the tray unloading unit 42 to wait for loading good-quality materials. In the initial state, the second tray unloading module 422 is driven by the fourth lifting mechanism 423 and is in a lifted state to facilitate receiving the material Tray transferred by the handling unit 6. When loading good-quality materials, the second tray unloading module 422 gradually descends under the drive of the fourth lifting mechanism 423 to facilitate the layer-by-layer loading of the material Tray. After the material Tray is fully loaded, the fourth lifting mechanism 423 descends to the lowest point, so that the second tray unloading module 422 is connected to the first tray unloading module 421 at the same horizontal plane for outwardly conveying the fully loaded material Tray for unloading.

[0043] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
