[0015] In this utility model, to solve the problem of low efficiency caused by the reliance on manual labor for inspection and sorting in existing equipment, the following technical solution is adopted: The transmission component includes a motor housing 7, which is placed on the ground. A maintenance door 8 is fixedly installed on the front end of the motor housing 7, and a first motor 10 is provided on the back of the maintenance door 8. The first motor 10 is fixedly installed on the motor housing 7. A drive gear 11 is fixedly connected to the top surface of the first motor 10.

A second motor 13 is fixedly installed at the lower end inside the lifting tube 9. A threaded rod 14 is fixedly connected to the top surface of the second motor 13. The threaded rod 14 is rotatably connected inside the lifting tube 9. A threaded seat 15 is fitted on the outer side of the threaded rod 14. Slider blocks are fixedly connected to both sides of the outer side of the threaded seat 15. A sliding groove is opened on the lifting tube 9 to cooperate with the slider. A lifting frame 16 is vertically installed and fixed on the top surface of the threaded seat 15. The lifting frame 16 has a lifting pipe 9 running through its top surface and a cross-shaped horizontal frame fixedly connected to it. The gripping component includes an electric push rod 17, which is installed and fixed on the top surface of the cross-shaped horizontal frame. Lifting plates 18 are slidably connected to the outer side of the cross-shaped horizontal frame. The bottom surface of the lifting plates 18 is installed and fixed on the telescopic end of the electric push rod 17. The top surface of the lifting plates 18 is connected to an air extraction pipe 19, and the other end of the air extraction pipe 19 is connected to an air pump 20. The air pump 20 is installed and fixed in the middle of the top surface of the cross-shaped horizontal frame. The bottom surface of the lifting plates 18 is connected to a rigid connecting pipe 21 in conjunction with the air extraction pipe 19. A suction cup 22 is fixedly connected to the lower end of the rigid connecting pipe 21.

[0016] Working Principle: In the use of this utility model, firstly, power is supplied to all electrical equipment. Then, the feeding belt 2 and the discharging belt 5 are both connected to the feeding and discharging equipment. The material to be tested is then conveyed to the feeding belt 2 via the feeding assembly line. During this process, the first motor 10, the second motor 13, the electric push rod 17, and the air pump 20 are simultaneously started. First, the second motor 13 drives the threaded rod 14 to rotate, thereby driving the threaded seat 15 to slide up and down, thus driving the lifting frame 16 to adjust the height of the suction cup 22. Then, the electric push rod 17 drives the lifting plate 18 to descend and stably press the suction cup 22 onto the material surface. Then, the air pump 20 draws air, causing the suction cup 22 to adsorb the material. The lifting operation is then reversed. The material is lifted up, and then the first motor 10 drives the drive gear 11 to rotate, which in turn drives the driven gear 12 to rotate, thus moving the material plate onto the pressure measuring needle plate 3. Then, the material plate is pressed down by the lifting operation. During this process, the suction cup 22 on the feed belt 2 grabs the material again, while the material plate on the pressure measuring needle plate 3 is energized to detect the voltage. Then, the cross horizontal frame continues to rotate. If the material that has passed the test is qualified, it will not move and will continue to rotate until it reaches above the discharge belt 5. Then, the air pump 20 releases air, causing the material to fall into the next process. If the material is not qualified, it will be released directly at the discharge port and fall into the recycling box 6 through the discharge inclined plate 4 to enter the recycling process. This process is repeated to complete the work efficiently.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
