DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] See also Figures 1 to 5 , the present invention provides a technical solution:

[0036] A powder metallurgy sprocket sorting device includes a glass turntable 1, a visual inspection device 2, and a sorting component 3;

[0037] The bottom of the glass turntable 1 is connected to a driving device and can rotate continuously under the action of the driving device;

[0038] There are at least two groups of visual inspection devices 2 arranged along the circumference of the glass turntable 1. The two groups of visual inspection devices 2 are used to inspect the upper and lower surfaces of the sprocket respectively. The visual inspection device 2 includes a frame 20 and a fill light 21 and an image acquisition probe 22 installed on the frame 20.

[0039] The fill light 21 in one group of the visual inspection devices 2 is located below the image acquisition probe 22 and the fill light 21 is located above the glass turntable 1;

[0040] In another group of visual inspection devices 2 , the fill light 21 is located above the image acquisition probe 22 and below the glass turntable 1 .

[0041] In this embodiment, the fill light 21 and the image acquisition probe 22 can be detachably mounted on the rack 20, wherein the image acquisition probe 22 is connected to the corresponding detection terminal by means of corresponding connecting cables and displays the detection results in real time through the display, and identifies qualified products and unqualified products.

[0042] The sorting assembly 3 is installed on one side of the glass turntable 1 and is used to sort the products, and sort the qualified and unqualified products to different conveying assemblies 33 in the sorting assembly 3 respectively.

[0043] Considering that existing sorting methods often use two independent sorting devices, in order to save equipment space and costs, the present invention also designs a single-station sorting assembly 3. Specifically, the sorting assembly 3 includes a protective frame 30, a double-rod cylinder 31, a sorting block 32, a conveying assembly 33, a material separation plate 34, and a switching mechanism 35. The protective frame 30 is composed of multiple protective plates.

[0044] The double-rod cylinder 31 is mounted on the top of the protection 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;

[0045] There are two groups of conveying components 33, which are arranged in the upper and lower parts of the protective frame 30 to realize the transportation of qualified and unqualified products; the conveying components 33 include rollers 330, conveyor belts 331 and drive motors 332, at least two of the rollers 330 are rotatably installed on the inner side of the protective frame 30 and the roller 330 at one end is connected to the drive motor 332.

[0046] The lower end of the dividing plate 34 is rotatably connected to the protective frame 30 and is arranged above the conveying assembly 33 located above. The switching mechanism 35 is installed on the side of the protective frame 30 and connected to the dividing plate 34 to adjust the position of the dividing plate 34.

[0047] 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 mounted 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. The magnetic block 351 is mounted on the side of the connecting seat 352 near the electromagnet 350. The side of the protective frame 30 also has a vertical plate 356 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. The ends of the connecting rod 353 are respectively rotatably connected to the upper side of the material separation plate 34 and the connecting seat 352. When the electromagnet 350 is de-energized, the connecting seat 352 is pushed open by the return spring 355. At this time, the upper end of the material separation plate 34 is at its highest point, and qualified products are transported via the conveyor assembly 33 below.

[0048] Since there is dust in the working environment, the dust will fall onto the glass turntable 1 and cause obstruction. In order to improve the accuracy of detection, a wiping assembly 4 for cleaning the glass turntable 1 is also 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 via a connecting member 5, so as 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 mounted on the side of the protective frame 30 by means of multiple tubular structural members. The upper end of the wiping wheel 41 is connected to a support shaft 45, and the support shaft 45 is mounted on the end of the support plate 40 by means of a one-way bearing.

[0049] In the present invention, in order to avoid the decrease in wiping effect caused by the unchanged position of the wiping wheel 41, one end of the connecting member 5 is rotatably connected to the connecting shaft 44 set at the upper end of the support 36 and 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 also provided on the support plate 40. A supporting spring 60 is fixed on the spring seat 6. The other end of the supporting spring 60 is sleeved with a supporting pin 61. The end of the supporting pin 61 is spherical. Through the action of the supporting spring 60, the end of the supporting pin 61 is always in contact with the connecting member 5 to ensure that the rack 50 is tightly engaged with the driving gear 42.

[0050] 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 adverse effects on the glass turntable 1 .

[0051] The working process and principle of the present invention are further described below:

[0052] The sprocket to be inspected is transported to the glass turntable 1 via the discharge mechanism. As the glass turntable 1 rotates continuously, the sprocket undergoes appearance inspection on both its upper and lower surfaces by at least two sets of visual inspection devices 2. If the sprocket is found to be qualified, when it reaches the sorting position, the sorting block 32 retracts under the drive of the double-rod cylinder 31 and pushes the qualified product to the conveyor assembly 33 below.

[0053] When a product is detected as unqualified, the electromagnet 350 is energized and repels the magnetic block 351, pushing the connecting seat 352 away from the electromagnet 350. At this time, the sorting plate 34 is pushed by the connecting rod 353 and rotated downward by a certain angle. The unqualified product is pushed by the sorting block 32 onto the conveyor assembly 33 above. During this process, the connecting member 5 is also pushed a certain distance, and with the help of the rack 50, it drives the drive gear 42 and the wiping wheel 41 to rotate by a certain angle (the one-way bearing is in a locked state at this time), thereby adjusting the position of the wiping wheel 41. When the product is detected as qualified, the electromagnet 350 is de-energized, the connecting seat 352 is reset, and the connecting member 5 and the rack 50 are reset. At this time, the rack 50 no longer drives the drive gear 42 to rotate, and the position of the wiping wheel 41 remains unchanged.

[0054] Based on the above, the present invention, with the help of the visual inspection device 2, can accurately inspect the appearance of the sprocket, timely discover unqualified products and qualified products, and improve the inspection and sorting efficiency; the sorting component 3 of the present invention can realize the sorting of qualified products and unqualified products while occupying only a single workstation area, while also reducing the equipment cost; the present invention also provides a wiping component 4 for cleaning the glass turntable 1 to keep the glass turntable 1 clean, and can also adjust the position of the wiping wheel 41 in time with the help of the switching mechanism 35 and the connecting member 5 to improve the cleaning effect.

[0055] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
