All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Example 1. Please refer to Figures 1-3 and Figures 6-8 , the present invention provides a technical solution: an automatic sorting device for defective parts, including a support frame 1, a motor 2 is fixedly connected to the outer wall of the support frame 1, the output end of the motor 2 penetrates the outer wall of the support frame 1 and is fixedly connected to the outer wall of the traction wheel 6, the outer wall of the traction wheel 6 is in transmission connection with the inner wall of the conveyor belt 7, a detection block 3 and a sorting arm 4 are fixedly connected to the outer wall of the support frame 1, a card slot 8 is opened in the inner wall of the conveyor belt 7, and further includes:

[0033] An alignment mechanism 5, the alignment mechanism 5 is arranged on the outer wall of the conveyor belt 7, and the alignment mechanism 5 includes a support plate 504, and the outer wall of the support plate 504 is inserted into the slot wall of the card slot 8;

[0034] The positioning mechanism 51 is arranged on the surface of the support plate 504. The positioning mechanism 51 includes a first support block 511. The outer wall of the first support block 511 is slidably connected to the inner wall of the support plate 504. An assembly groove 512 is formed at the top of the first support block 511. A first guide rod 513 is fixedly connected to the groove wall of the assembly groove 512. A clamping assembly 52 is arranged inside the assembly groove 512. The clamping assembly 52 includes a second support block 521. The second support block 521 is slidably connected to the outer wall of the first guide rod 513 through a guide hole 522 formed in the outer wall. A limiting groove 524 is formed in the outer wall of the second support block 521. The groove wall of the limiting groove 524 is slidably connected to the outer wall of the positioning block 525. A guide groove 526 is formed in the outer wall of the positioning block 525. A support assembly 53 is arranged on the outer wall of the second support block 521. The positioning block 525 is used to position the parts. The assembly groove 512 is used to limit the positioning block 525. When the automatic sorting device for defective parts is put into use, the motor 2 is started to drive the traction wheel 6 to rotate. The conveyor belt 7 is tractioned by the traction wheel 6. The support plate 504 is inserted into the card slot 8, so that the conveyor belt 7 drives the sorting mechanism 5 through the support plate 504 to sort the defective parts. The operator opens the sorting mechanism 5 to insert the parts into the assembly groove 523. The parts extrude the support assembly 53, so that the support assembly 53 drives the second support block 521 to slide on the outer wall of the first guide rod 513. At the same time, the second support block 521 drives the positioning block 525 to contact the groove wall of the assembly groove 512, and the positioning block 525 is extruded by the assembly groove 512, so that the positioning block 525 slides on the outer wall of the second support block 521 towards the parts and contacts the outer wall of the parts to position the parts, adjust the state of the parts, which is convenient for detecting defective parts. At the same time, when the second support block 521 slides on the inner wall of the assembly groove 512, it reversely extrudes the parts, so that the parts are neatly fixed inside the assembly groove 512.
