[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] The present invention provides the following preferred embodiments:

[0029] Example 1, as Figures 1-6 As shown, a segmented screw detection mechanism includes a base plate 1, and also includes a first detection mechanism and a second detection mechanism.

[0030] The first inspection mechanism includes a first industrial camera 2, a transport component and a push component. The transport component is located above the base plate 1, the first industrial camera 2 is mounted above the transport component, and the push component is mounted on one side of the transport component.

[0031] The second inspection mechanism includes a second industrial camera 3, a rotating component and a moving component. The rotating component is located at one end of the transport component, the moving component is located above the rotating component, and the second industrial camera 3 is located above the moving component.

[0032] The industrial camera specifically refers to a CCD industrial camera, which uses a high-resolution CCD camera and advanced vision algorithms to achieve a detection accuracy of up to ±0.002mm. It can accurately measure the length of screws and other key dimensions. Industrial cameras are existing technology and will not be described in detail here.

[0033] like Figures 1-6 As shown, the transport assembly includes a conveyor 4, a support frame 6, and two side plates 5. Both side plates 5 are fixed to the top of the base plate 1. The conveyor 4 is installed between the two side plates 5. The support frame 6 is fixed to the outer wall surface of the two side plates 5. The first industrial camera 2 is set on one side of the support frame 6.

[0034] Conveyor 4 is existing technology and will not be described in detail here;

[0035] In use, the screws are neatly placed on the conveyor 4, which carries the screws. When the screws pass the support frame 6, they are photographed by the first industrial camera 2 on one side. The photographed image is compared with the standard length screw image stored in the controller to determine the length of the screw. When the screw is determined to be of unqualified length, the controller controls the push component to work and push out the unqualified screw.

[0036] like Figures 1-6 As shown, the pushing assembly includes an L-shaped plate 7 and a cylinder 8. The L-shaped plate 7 is fixedly installed on the outer wall of a side plate 5, and the cylinder 8 is fixedly installed on the top of the L-shaped plate 7. The output end of the cylinder 8 is provided with a top plate 31.

[0037] Cylinder 8 is electrically connected to the controller;

[0038] When a screw is determined to be of unacceptable length, the controller controls the cylinder 8 to work. The cylinder 8 is installed on one side of the side plate 5 via the L-shaped plate 7. The cylinder 8 drives the top plate 31 to move, pushing out the unacceptable screw in front.

[0039] The qualified screws will continue to move under the action of conveyor 4.

[0040] like Figures 1-6 As shown, the rotating assembly includes a mounting plate 17, a first motor 10, a first driving wheel 11, a first driven wheel 12, a second driving wheel 13, a second driven wheel 14, a first belt 18, a second belt 19, two connecting shafts 15, two rollers 16, and four support plates 20. The four support plates 20 are all fixedly mounted on the top of the base plate 1. Each connecting shaft 15 is rotatably mounted between two support plates 20. Each roller 16 is fixed to the outer wall of one connecting shaft 15. The mounting plate 17 is fixedly mounted on the top of the base plate 1. The first motor 10 is fixedly mounted on one side of the mounting plate 17. The first driving wheel 11 is fixedly connected to the output end of the first motor 10. The first driven wheel 12 is fixedly mounted on one end of one of the connecting shafts 15. The first belt 18 is sleeved on the outer walls of the first driving wheel 11 and the first driven wheel 12. The second driving wheel 13 is fixed to one side of the first driven wheel 12. The second driven wheel 14 is fixed to one end of the other connecting shaft 15. The second belt 19 is simultaneously on the outer walls of the second driving wheel 13 and the second driven wheel 14.

[0041] After the screw passes through the first section of the first industrial camera 2 for inspection, the screw on the conveyor 4 enters between the two rollers 16 under the guidance of the slide plate 35. The second industrial camera 3 can take pictures of the screw above the two rollers 16 and compare the pictures with the standard screw pictures stored in the controller to determine whether there are defects on the surface of the screw. When the screw is determined to be unqualified, the unqualified screw is pushed into one of the second collection tanks 34 by the moving component, while the qualified screw is pushed into the other second collection tank 34 by the moving component.

[0042] When different sides of a screw need to be inspected, the first motor 10 drives the first drive wheel 11 to rotate. When the first drive wheel 11 rotates, it drives the first driven wheel 12 to rotate via the first belt 18. When the first driven wheel 12 rotates, it drives the second drive wheel 13 on one side to rotate. The second driven wheel 14 rotates via the second belt 19, so that the two rollers 16 can rotate on the two support plates 20 respectively, thereby driving the screw between the two rollers 16 to rotate. This allows the second industrial camera 3 to take pictures of the different sides of the screw above the two rollers 16, making it convenient to inspect the different sides of the screw. The inspection is more comprehensive and there are no blind spots.

[0043] like Figures 1-6 As shown, the moving assembly includes a fixed plate 22, a second motor 23, a gear 24, a rack 25, a slide 27, a fixed rod 28, a horizontal plate 29, two push plates 30, and two mounting brackets 21. The fixed plate 22 is fixedly installed on the top of the base plate 1. The second motor 23 is installed below the fixed plate 22. The gear 24 is fixedly installed at the output end of the second motor 23. The two mounting brackets 21 are symmetrically fixedly installed on the top of the base plate 1. The fixed rod 28 is installed below the two mounting brackets 21. The slide 27 is opened at the bottom end of the fixed rod 28. The rack 25 is slidably installed in the slide 27 and meshes with the gear 24. The two push plates 30 are both located on the side of the rack 25 away from the gear 24. The horizontal plate 29 is fixedly installed between the two mounting brackets 21. The second industrial camera 3 is installed on one side of the horizontal plate 29. A second collection groove 34 is provided on the side of the two push plates 30 away from each other. Each second collection groove 34 is located above the base plate 1.

[0044] When the screw passes the inspection, the controller drives the second motor 23 to rotate. The second motor 23 drives the gear 24 to rotate, and the gear 24 drives the rack 25 to move. The rack 25 can slide inside the slide groove 27 by setting a slider at the top. While the rack 25 is sliding, it will drive the two push plates 30 to move. While the push plates 30 are moving, they will drive the screw between the two rollers 16 to move, and collect the screw into one of the second collection grooves 34.

[0045] When a screw fails the inspection, the controller drives the second motor 23 to work, causing the gear 24 to rotate in the opposite direction. At this time, the rack 25 moves in the opposite direction, driving the two push plates 30 to move in the opposite direction, pushing the defective screw into another second collection groove 34 for collection. It should be noted that the distance between the two push plates 30 is greater than the length of the screw, and the push plates 30 are located between the two rollers 16 without contacting the rollers 16.

[0046] like Figures 1-6 As shown, a groove 32 is provided on the side plate 5 away from the cylinder 8, and a first collection groove 33 is provided on the side of the groove 32 away from the cylinder 8. The first collection groove 33 is located above the bottom plate 1.

[0047] By providing a groove 32 in the output direction of cylinder 8, a clearance function is achieved. The groove 32 will not affect the screw ejection. When the defective screw leaves the conveyor 4, it will enter the first collection tank 33 for collection.

[0048] like Figures 1-6 As shown, a sliding plate 35 is provided between the conveyor 4 and a roller 16. One end of the sliding plate 35 is fixedly connected to two side plates 5. The sliding plate 35 connects the conveyor 4 and the roller 16 and guides the screw, so that the screw can be accurately moved between the two rollers 16 for subsequent inspection.
