[0024] See also Figure 1 - Figure 6 As shown, a defective surgical instrument screening device comprises a workbench 1 and a conveyor belt 20; a base 21 is welded and fixed on the workbench 1, and two groups of bases 21 are provided. An industrial camera 22 is welded and fixed on the base 21, and a flip mechanism is provided on the conveyor belt 20, and the flip mechanism comprises four groups of casings 28, and the casings 28 are welded and fixed on the connecting blocks 43, and the connecting blocks 43 are rotatably connected to the two groups of supporting frames 23, and the supporting frames 23 are fixed to the workbench 1 by welding, and one side of the connecting block 43 is fixed to the first rotating wheel 24 by welding, and the first rotating wheel 24 is sleeved with a belt 25, and the bottom end of the belt 25 is sleeved on the second rotating wheel 26, and the second rotating wheel 26 is connected to the output shaft of the servo motor 27, and the second rotating wheel 26 is rotatably connected to the inside of the workbench 1, and the servo motor 27 is provided inside the workbench 1, and two groups of fixing plates 38 are welded and fixed inside the casing 28, and a groove 39 is provided on the workbench 1;

[0025] During operation, an intelligent sorting device for medical consumables in the above technology, in the process of sorting defective products, since the medical consumables always have one side facing downwards, it is difficult to detect the back side when the defective detection camera is detecting, so the medical consumables need to be turned over later, and then another detection operation is performed, which is relatively time-consuming. Through the structural design of the flipping mechanism, it is convenient to flip the hemostatic forceps transported on the conveyor belt 20, so that the industrial camera 22 can detect the front and back sides of the hemostatic forceps. The hemostatic forceps are transported on the conveyor belt 20 and photographed by the industrial camera 22. The defective products will be taken away by the robotic arm. The conveyor belt 20 is provided with multiple sections and gaps are left on a group of conveyor belts 20. When the hemostatic forceps are transported to the inside of the housing 28, the servo motor is used to turn the hemostatic forceps over. 27 drives the second rotating wheel 26 to rotate, and the second rotating wheel 26 transmits the rotation to the first rotating wheel 24 through the belt 25 to rotate the first rotating wheel 24. Since the shell 28 is provided with four groups, the servo motor 27 is controlled to make the first rotating wheel 24 rotate 90° each time, thereby driving the connecting block 43 to rotate. Under the continuous rotation of the connecting block 43, the hemostatic forceps inside the shell 28 will be turned over and transported again through the conveyor belt 20, so that the industrial camera 22 fixed on the base 21 can take pictures of the front and back sides of the hemostatic forceps, wherein a groove 39 is opened on the workbench 1 to ensure that the shell 28 will not abut against the workbench 1 during rotation, and two groups of fixing plates 38 are fixed inside the shell 28 to fill the space inside the shell 28 to adapt to the shape of the hemostatic forceps.

[0026] Furthermore, a magnetic column 30 is inserted inside the fixing plate 38, and a first spring 29 is sleeved on the magnetic column 30. The first spring 29 is arranged inside a set of fixing plates 38. The side of the magnetic column 30 away from the casing 28 is attracted by the magnet 32. The magnet 32 ​​is glued and fixed inside the fixing frame 31. The bottom end of the fixing frame 31 is welded and fixed on the workbench 1.

[0027] During operation, through the structural design of the first spring 29, the magnetic column 30 and the fixing frame 31, on the two groups of shells 28 that are kept horizontal with the conveyor belt 20, the magnet 32 ​​attracts the magnetic column 30, thereby storing the magnetic column 30 in the fixing plate 38, and the shell 28 in the vertical state, its magnetic column 30 will support the hemostatic forceps inside the shell 28, thereby ensuring that the hemostatic forceps can be fixed in the shell 28 during the flipping process, when the magnet 32 ​​and the magnetic column 30 are attracted, the hemostatic forceps can smoothly enter the shell 28 and be transported out of the shell 28, and when the shell 28 is in the vertical state, the magnetic column 30 will support the hemostatic forceps inside the shell 28 under the action of the first spring 29 to fix it.

[0028] Furthermore, a receiving groove 35 is provided inside the housing 28, a telescopic plate 33 is inserted inside the receiving groove 35, a second spring 34 is welded and fixed on the telescopic plate 33, and a side of the second spring 34 away from the telescopic plate 33 is welded and fixed on the inner wall of the receiving groove 35;

[0029] During operation, the telescopic plate 33 can be received in the receiving groove 35 through two sets of second springs 34. The telescopic plate 33 prevents the distance between the end of the conveyor belt 20 and the sleeve 28 from being too large, ensuring that the hemostatic forceps can be smoothly transported to the sleeve 28. When the sleeve 28 rotates, the telescopic plate 33 can also be received in the receiving groove 35 by abutting against the groove 39.

[0030] Furthermore, the top end of the telescopic plate 33 contacts the fixing strip 36, and the fixing strip 36 is welded and fixed to the casing 28;

[0031] When working, the fixing strip 36 is designed to be triangular. Since there is a height difference between the telescopic plate 33 and the housing 28 , the fixing strip 36 can ensure that the hemostatic forceps can smoothly pass through the telescopic plate 33 and the fixing strip 36 into the interior of the housing 28 .

[0032] Furthermore, two sets of fixing blocks 37 are welded and fixed inside the casing 28, and the fixing blocks 37 are provided with arc surfaces;

[0033] During operation, the fixing block 37 is fixed inside the casing 28 and an arc surface is provided on the fixing block 37 so as to better fit the handle of the hemostatic forceps.

[0034] Furthermore, a support block 40 is welded and fixed on the workbench 1, a protective ring 41 is welded and fixed on the support block 40, and a protective strip 42 is welded and fixed on the base 21;

[0035] During operation, the protective ring 41 is close to the outer side of the conveyor belt 20 to guide the hemostat during transportation. A protective strip 42 is fixed on the base 21 to block the inner side of the conveyor belt 20 to ensure normal transportation of the hemostat on the conveyor belt 20.

[0036] Working principle: In the process of sorting defective products, a medical consumable intelligent sorting device in the prior art has one side facing downwards. Therefore, it is difficult to detect the back side of the medical consumable when the defective detection camera is detecting it, so the medical consumable needs to be turned over later and then detected again, which is time-consuming. In this case, a defective screening device for surgical instruments realizes the function of conveniently flipping the hemostatic forceps transported on the conveyor belt 20 through the structural design of the flipping mechanism, so that the industrial camera 22 can detect the front and back sides of the hemostatic forceps. The hemostatic forceps is transported on the conveyor belt 20 and photographed by the industrial camera 22. The defective products will be taken away by the robot arm. The conveyor belt 20 is provided with multiple sections and a gap is left on a group of conveyor belts 20. When the hemostatic forceps is transported to the inside of the casing 28, At this time, the second rotating wheel 26 is driven to rotate by the servo motor 27, and the second rotating wheel 26 transmits the rotation to the first rotating wheel 24 through the belt 25 to rotate the first rotating wheel 24. Since the shell 28 is provided with four groups, the servo motor 27 is controlled to make the first rotating wheel 24 rotate 90° each time, thereby driving the connecting block 43 to rotate. Under the continuous rotation of the connecting block 43, the hemostatic forceps inside the shell 28 will be turned over and transported again by the conveyor belt 20, so that the industrial camera 22 fixed on the base 21 can take pictures of the front and back sides of the hemostatic forceps, wherein a groove 39 is opened on the workbench 1 to ensure that the shell 28 will not abut against the workbench 1 during rotation, and two groups of fixing plates 38 are fixed inside the shell 28 to fill the space inside the shell 28 to adapt to the shape of the hemostatic forceps.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
