Detailed Embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 5 , the present invention provides a technical solution: A sorting device for powder metallurgy sprockets, comprising a glass turntable 1, a vision detection device 2 and a sorting component 3; The bottom of the glass turntable 1 is connected to a driving device and can rotate continuously under the action of the driving device; There are at least two sets of the visual detection devices 2, which are arranged along the circumferential direction of the glass turntable 1. The two sets of visual detection devices 2 are respectively used to detect the upper and lower surfaces of the sprocket; the visual detection device 2 includes a frame 20, a supplementary light 21 and an image acquisition probe 22 installed on the frame 20; In one set of the visual detection devices 2, the supplementary light 21 is located below the image acquisition probe 22 and the supplementary light 21 is located above the glass turntable 1; In the other set of the visual detection devices 2, the supplementary light 21 is located above the image acquisition probe 22 and the supplementary light 21 is located below the glass turntable 1.

[0024] In this embodiment, the supplementary light 21 and the image acquisition probe 22 are both detachably installed on the frame 20. Among them, the image acquisition probe 22 is connected to a corresponding detection terminal by means of a corresponding connection cable, and the detection result is displayed in real time through a display, and qualified products and unqualified products are identified.

[0025] The sorting component 3 is installed on one side of the glass turntable 1 and is used to sort products, and the qualified and unqualified products are respectively sorted onto different conveying components 33 in the sorting component 3.

[0026] Considering that the existing sorting methods are mostly realized by using two independent sorting devices, in order to save equipment space and cost, the present invention also designs a single-station sorting component 3. Specifically, the sorting component 3 includes a protective frame 30, a double-rod cylinder 31, a sorting block 32, a conveying component 33, a material dividing plate 34 and a switching mechanism 35. The protective frame 30 is formed by splicing a plurality of protective plates; The double-rod cylinder 31 is installed on the top of the protective frame 30 by means of a cylinder seat, and the output end of the double-rod cylinder 31 is connected to the sorting block 32; There are two sets of the conveying components 33, which are respectively arranged up and down in the protective frame 30 to realize the conveying of qualified and unqualified products; the conveying component 33 includes a roller shaft 330, a conveyor belt 331 and a driving motor 332. At least two of the roller shafts 330 are rotatably installed inside the protective frame 30, and the roller shaft 330 at one end is connected to the driving motor 332.

[0027] The lower end of the material dividing plate 34 is rotatably connected inside the protective frame 30 and is arranged above the conveying component 33 located above. The switching mechanism 35 is installed on the side of the protective frame 30 and is connected to the material dividing plate 34 to realize the adjustment of the position of the material dividing plate 34.

[0028] In this embodiment, the switching mechanism 35 includes an electromagnet 350, a magnetic block 351, a connecting seat 352 and a connecting rod 353. The electromagnet 350 is installed on the side of the protective frame 30, and the connecting seat 352 is also slidably connected to a slide rail 354 provided on the side of the protective frame 30. A magnetic block 351 is installed on one side of the connecting seat 352 close to the electromagnet 350. A vertical plate 356 is further provided on the side of the protective frame 30 and is located on one side of the connecting seat 352. The connecting seat 352 is located between the vertical plate 356 and the electromagnet 350. A return spring 355 is provided between the vertical plate 356 and the connecting seat 352. Both ends of the connecting rod 353 are rotatably connected to the upper side part of the material distribution plate 34 and the connecting seat 352 respectively. When the electromagnet 350 is not energized, the connecting seat 352 is pushed open by the return spring 355. At this time, the upper end of the material distribution plate 34 is at the highest point, and qualified products are conveyed by the conveying assembly 33 below.

[0029] Since there will be dust in the working environment, the above-mentioned dust will fall onto the glass turntable 1 and cause blockage. In order to improve the accuracy of detection, a wiping assembly 4 for cleaning the glass turntable 1 is further installed on one side of the sorting assembly 3. The wiping wheel 41 in the wiping assembly 4 is also connected to the switching mechanism 35 in the sorting assembly 3 through a connecting member 5 to be able to drive the wiping wheel 41 to rotate a certain angle. Specifically, the wiping assembly 4 includes a support plate 40, a wiping wheel 41 and a driving gear 42. A sponge pad 43 is installed at the lower end of the wiping wheel 41. The support plate 40 is installed on the side of the protective frame 30 by means of a plurality of tubular structural members. The upper end of the wiping wheel 41 is connected to a support shaft 45, and the support shaft 45 is installed at the end of the support plate 40 by means of a one-way bearing. In the present invention, in order to avoid the decrease in the wiping effect caused by the fixed position of the wiping wheel 41, one end of the connecting member 5 is rotatably connected to a connecting shaft 44 provided at the upper end of the support 36 and is limited by a locking member. The other end of the connecting member 5 is provided with a rack 50 that cooperates with the driving gear 42. A spring seat 6 is further provided on the support plate 40. A top support spring 60 is fixed on the spring seat 6. The other end of the top support spring 60 is sleeved with a top support pin 61. The end of the top support pin 61 is spherical. Through the action of the top support spring 60, the end of the top support pin 61 is always in contact with the connecting member 5 to ensure the tight meshing of the rack 50 and the driving gear 42.

[0030] In the embodiment of the present invention, the lower end of the sorting block 32 is 1-5 mm away from the glass turntable 1, which can avoid rigid friction between the sorting block 32 and the glass turntable 1 and reduce the adverse impact on the glass turntable 1.

[0031] The working process and principle of the present invention are further introduced below: The sprocket to be detected is conveyed to the glass turntable 1 via the discharging mechanism. Under the continuous rotation of the glass turntable 1, the sprocket is subjected to appearance inspection on its upper and lower surfaces respectively by at least two sets of vision detection devices 2. If the inspected product is qualified, when the qualified sprockets reach the sorting position, the sorting block 32 retracts driven by the double-rod cylinder 31 and pushes the qualified products onto the lower conveying component 33; When the inspected product is unqualified, the electromagnet 350 is energized and repels the magnetic block 351, driving the connecting seat 352 to move away from the electromagnet 350. At this time, the material distribution plate 34 is pushed by the connecting rod 353 and rotates downward by a certain angle, and the unqualified products are pushed by the sorting block 32 onto the upper conveying component 33. During this process, the connecting member 5 is also pushed a certain distance, and by means of the rack 50 driving the driving gear 42 and the wiping wheel 41 to rotate a certain angle (the one-way bearing is in the locked state at this time), the position of the wiping wheel 41 is adjusted. When the inspected product is qualified, the electromagnet 350 is de-energized, the connecting seat 352 is reset, the connecting member 5 and the rack 50 are reset. At this time, the rack 50 does not drive the driving gear 42 to rotate, and the position of the wiping wheel 41 remains unchanged.

[0032] Based on the above, with the help of the vision detection device 2, the present invention can accurately detect the appearance of the sprocket, timely discover unqualified products and qualified products, and improve the detection and sorting efficiency; the sorting component 3 of the present invention can realize the sorting of qualified products and unqualified products on the premise of only occupying the area of a single station, and at the same time reduce the equipment cost; a wiping component 4 for cleaning the glass turntable 1 is also provided in the present invention to keep the glass turntable 1 clean, and the position of the wiping wheel 41 can be adjusted timely by means of the switching mechanism 35 and the connecting member 5 to improve the cleaning effect.

[0033] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not deviate from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
