Description

Technical Field

[0001] This utility model relates to the field of material sorting technology, and in particular to a belt sorting device. Background Technology

[0002] To ensure the quality of parts produced in large quantities in industrialized markets, parts need to be sorted to remove defective products. Manual sorting is inefficient and has a high error rate. Common sorting devices are mostly ring-shaped structures that use glass turntables to carry materials and perform machine vision recognition during rotation. This type of device has high space utilization, but it is not convenient for detecting parts with protruding structures in the middle, and it has poor adaptability to parts of different sizes. Different glass turntables often need to be replaced according to different sizes, which increases downtime. Utility Model Content

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0027] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] As attached Figure 1 Appendix Figure 2 The diagram shows a belt sorting device according to this utility model, including a frame 3. A first conveyor 1 and a second conveyor 2 for conveying parts to be tested are mounted on the frame 3. The second conveyor 2 is connected to the end of the first conveyor 1. A vibratory feeding device 40 for placing the parts to be tested one by one onto the first conveyor 1 is mounted at one end of the frame 3. (See attached diagram.) Figure 3 As shown, the part to be tested includes an upper shaft section 41 and a lower shaft section 43, with a flange 42 formed between the upper shaft section 41 and the lower shaft section 43. In this embodiment, the part to be tested is a rivet. (See attached diagram) Figure 5 As shown, the first conveying device 1 includes two parallel, spaced-apart first belts 11 with adjustable spacing. The bearing surface of the first belts 11 is the upper surface. The lower shaft section 43 of the part to be tested is located in the gap between the two first belts 11. The upper surface of the first belts 11 contacts the lower end face of the flange 42 and drives the part to be tested to move. (See attached diagram) Figure 6As shown, the second conveying device 2 includes two parallel, spaced-apart, and adjustable second belts 21. The bearing surface of the second belts 21 is the side. The upper shaft section 41 of the part to be tested is clamped between the two second belts 21 and moves with the second belts 21. The position of the second belts 21 is higher than that of the first belt 11. When the part to be tested is lifted and moved to the end of the first belt 11, the upper shaft section 41 just enters the space between the second belts 21 and continues to move.

[0029] The first conveying device 1 has first detection positions and second detection positions spaced apart along the conveying direction. A first camera 5 for photographing the part under test is mounted above the first detection position, and several second cameras 6 for photographing the sides of the upper shaft section 41 are mounted around the second detection positions. Specifically, see attached... Figure 7 As shown, a column 13 and a height adjustment component 14 vertically slidably connected to the column 13 are installed on one side of the first conveying device 1. The height adjustment component 14 has a cantilever 15 extending above the second detection position. Several guide rails 16 extending in all directions are installed on the cantilever 15. The guide rails 16 have scales and adjustment sliders 17 are installed on the guide rails 16. The second camera 6 is connected to the adjustment slider 17 so that the position of the second camera 6 can be adjusted according to the size of the part. In this embodiment, there are four second cameras 6, which can completely capture the circumferential surface of the upper shaft section 41. The lens of the second camera 6 is slightly tilted downward and the tilt angle is adjustable. While capturing the circumferential surface, it can also capture the upper end surface of the flange 42, making the detection more complete.

[0030] A third camera 7 for photographing the lower end face of the flange 42 is installed below the second conveying device 2. In this embodiment, there are two third cameras 7, which are slightly tilted in different directions to avoid blind spots. A fourth camera 8 for detecting the length of the part to be measured is installed on one side of the first conveying device 1. The combination of multiple cameras enables the inspection of the size and appearance of the part, thereby distinguishing between good and defective products.

[0031] The second conveyor 2 is equipped with a first channel 9, a second channel 10 and an air blowing device at its end. The opening of the first channel 9 is located below the second conveyor 2, and the opening of the second channel 10 faces the direction from which the part to be tested comes. The air blowing device is used to blow the good parts after testing into the second channel 10, while the defective parts move to the end of the second belt 21 and fall freely into the first channel 9 under gravity, thus completing the sorting of good and defective parts.

[0032] As attached Figure 5As shown, a stabilizer 23 is installed on the outer side of the first belt 11. A first bearing 24 and a second bearing 25, with their center lines perpendicular to each other, are mounted on the stabilizer 23. The circumferential surface of the first bearing 24 is close to the outer surface of the first belt 11, and the circumferential surface of the second bearing 25 is close to the upper surface of the first belt 11. This restricts the jumping of the first belt 11, making material conveying more stable and reliable. The two first belts 11 of the first conveyor device 1 are driven to rotate by a first motor 12, and the two second belts 21 of the second conveyor device 2 are each driven to rotate by a second motor 22. The two second motors 22 ensure that the second belts 21 follow synchronously, with consistent speed and direction, avoiding misalignment that could affect product conveying and imaging, and improving the detection effect.

[0033] Two second belts 21 are respectively mounted on a base plate 30, as shown in the attached figure. Figure 8 As shown, an adjusting block 31 is mounted on the bottom of the substrate 30, and a base 32 fixedly connected to the frame 3 is mounted below the second conveying device 2. The base 32 has fixing members 33 on both sides and an adjusting rod 34 that passes through the fixing members 33 and is spirally connected to the adjusting block 31. By rotating the adjusting rod 34, the distance between the two substrates 30 can be adjusted, allowing the two second belts 21 to move closer or further apart to accommodate parts of different sizes. The base 32 has a scale 35, and the upper surface of the substrate 30 also has a scale. A pointer 36 for indicating the scale 35 is connected to the adjusting block 31, making adjustment more convenient, quick, and intuitive. The width adjustment between the first belts 11 is similar, making the sorting device more versatile.

Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
