Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 , 2 As shown, a product quality visual inspection device includes a processing table 1. Two first hydraulic cylinders 2 are fixedly installed on both sides of the upper surface of the processing table 1. Mounting rods 3 are fixedly installed at the output ends of the two first hydraulic cylinders 2. A top plate 4 is fixedly installed between the top ends of the two mounting rods 3. A first monitoring detector 7 is fixedly installed in the middle of the lower surface of the top plate 4. A servo motor 5 is fixedly installed on one side surface of the top plate 4. A bidirectional lead screw 12 is installed at the output end of the servo motor 5. Two lead screw sleeves 13 are sleeved in the middle of the bidirectional lead screw 12. Guide blocks 10 are fixedly installed on the circumference of the two lead screw sleeves 13. Mounting clamps 11 are fixedly installed at the lower ends of the two guide blocks 10. Rotating shafts 14 are rotatably installed between the inner walls on both sides of the two mounting clamps 11. Swing plates 15 are installed on the circumference of the two rotating shafts 14. A second monitoring detector 8 is fixedly installed at the lower ends of the two swing plates 15. An adjustment assembly 9 is provided on the top plate 4.

[0020] like Figure 1 As shown, a plurality of positioning rods 16 are fixedly installed on the upper surface of the processing table 1, and a mounting frame 17 is fixedly installed on the top of the plurality of positioning rods 16. An electric conveyor belt 18 is installed on the mounting frame 17. When the product is placed on the upper surface of the electric conveyor belt 18, the electric conveyor belt 18 works to move the product to the first monitoring detector 7 and the second monitoring detector 8 for detection.

[0021] like Figure 1 As shown, a guide rod 6 is fixedly installed between the two mounting rods 3, and the two guide blocks 10 are slidably installed through the middle of the guide rod 6 to ensure better stability when the two second monitoring detectors 8 move.

[0022] like Figure 2 , 3As shown in Figure 4, the adjustment assembly 9 includes a second hydraulic cylinder 902, a slide groove 905, and two gears 908. The second hydraulic cylinder 902 is fixedly installed on the upper surface of the top plate 4. The slide groove 905 is formed on the lower surface of the top plate 4. The two gears 908 are respectively fixedly installed on the top ends of the two rotating shafts 14. A slide rod 906 is slidably installed inside the slide groove 905. A second toothed plate 907 is fixedly installed at the lower end of the slide rod 906. A positioning plate 904 is fixedly installed at the top end of the second toothed plate 907. A first toothed plate 901 is fixedly installed at the lower end of the positioning plate 904. The second toothed plate 907 and the first toothed plate 901 are respectively meshed with the opposite sides of the two gears 908. A connecting plate 903 is fixedly installed on the upper surface of the second toothed plate 907. The output end of the second hydraulic cylinder 902 is located on the surface of the connecting plate 903. By extending and retracting the output ends of the two first hydraulic cylinders 902, the top plate 4 can be moved up or down, thereby adjusting the first monitoring... After the height of the control detector 7 and the second monitoring detector 8 is adjusted, the output end of the servo motor 5 drives the bidirectional lead screw 12 to rotate. This causes the lead screw sleeve 13 to move towards each other in the middle of the bidirectional lead screw 12, thereby driving the two second monitoring detectors 8 to move towards each other to adjust the distance between them. After adjustment, the output end of the second hydraulic cylinder 902 drives the second gear plate 907 to move forward, which in turn drives the first gear plate 901 to move. Since the first gear plate 901 and the second gear plate 907 are meshed on the upper and lower sides of the two gears 908 respectively, the two gears 908 can be driven to move in opposite directions to adjust the angle of the two second monitoring detectors 8. The detectors of this device can be positioned according to the product specifications, enabling thorough inspection of products of different specifications.

[0023] The working principle of this product quality visual inspection equipment:

[0024] In use, the positions of the first monitoring detector 7 and the second monitoring detector 8 are first adjusted according to the product specifications. This is achieved by extending and retracting the output ends of the two first hydraulic cylinders 2, which moves the top plate 4 up or down, adjusting the height of the first monitoring detector 7 and the second monitoring detector 8. After height adjustment, the output end of the servo motor 5 drives the bidirectional lead screw 12 to rotate, causing the lead screw sleeve 13 to move towards each other in the middle of the bidirectional lead screw 12. This simultaneously drives the two second monitoring detectors 8 to move towards each other, adjusting the distance between them. After adjustment, the output end of the second hydraulic cylinder 902 drives the second toothed plate. 907 moves forward, which in turn moves the first toothed plate 901. Since the first toothed plate 901 and the second toothed plate 907 are meshed on the upper and lower sides of the two gears 908 respectively, the two gears 908 can be driven to move in opposite directions to adjust the angle of the two second monitoring detectors 8. The detectors of this device can be adjusted according to the product specifications, and can fully inspect products of different specifications. After the positions of the first monitoring detector 7 and the second monitoring detector 8 are adjusted, the product is placed on the upper surface of the electric conveyor belt 18. The electric conveyor belt 18 then moves the product to the first monitoring detector 7 and the second monitoring detector 8 for inspection.
