Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically to a blowing air sorting and collection device for visual inspection. Background Technology

[0002] In the semiconductor industry, visual inspection equipment is typically used to inspect and sort components. Currently, rotary visual inspection equipment is commonly used. A feeder transports components to a rotary table, which rotates and is inspected from multiple sides by a camera. The inspection system identifies qualified and unqualified products, and finally, an air-blowing sorting and collection device is used to classify and collect them. The inspection of components usually also includes the bottom surface, which is photographed by a camera under the disc. Therefore, the disc is required to be made of transparent material, and acrylic sheets are currently commonly used as the base plate.

[0003] When the disc is fed by the feeding mechanism, the feeding position is relatively random. Therefore, the component needs to be aligned by the guiding mechanism. During this process, the component will rub against the disc. Over long-term operation, the friction will gradually cause scratches on the disc. These scratches will interfere with the detection when the lower camera takes pictures. Therefore, these worn discs need to be replaced in time. However, part of the existing air-blowing classification and collection device is located on the upper part of the disc. This means that this part needs to be removed before the disc can be removed, which makes the disc replacement work quite cumbersome. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0022] In existing technologies, a portion of the air-sorting and collecting device is located on the upper part of the disc, which means that this part needs to be removed before the disc can be removed, making the disc replacement process quite cumbersome.

[0023] To address the problems existing in the relevant prior art, this utility model proposes a visual inspection air-blowing classification and collection device. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. The direction of the carrier belt forward movement is defined as the left-right direction, the direction that is horizontally perpendicular to the direction of the carrier belt forward movement is defined as the front-back direction, and the vertical direction is defined as the up-down direction.

[0024] Please see Figure 1 This utility model proposes a visual inspection air-blowing sorting and collection device, specifically including a hopper 1, a material box 2, a connecting frame 3, and air nozzles 4. The hopper 1 is provided with multiple pull-out material boxes 2. When in use, the material boxes 2 are inserted into the hopper 1. The connecting frame 3 specifically includes a connecting block 301, a fixing frame 302, and an L-shaped arm 303. The connecting block 301 is fixed to the upper part of the hopper 1. The fixing frame 302 is connected to the connecting block 301 through a hinge shaft, and the fixing frame 302 can rotate around the hinge shaft. The side of the connecting block 301 is also provided with a support block 304. When the fixing frame 302 is in the working position, the fixing frame 302 is in a horizontal state. The support block 304 is used to support and restrict the rotation of the fixing frame 302. There are multiple L-shaped arms 303, and each L-shaped arm 303 is provided with an air nozzle 4. The number of air nozzles 4 is the same as the number of material boxes 2 in the hopper 1, and the air blowing direction of the air nozzles 4 is towards the corresponding material box 2.

[0025] Please see Figure 2The hopper 1 specifically includes a bottom plate 101, two side plates 102, and a top plate 103. The bottom plate 101, two side plates 102, and a top plate 103 form a hopper that runs through both sides. The hopper 1 has openings on both sides, and the material boxes 2 are inserted into the hopper 1 through the side openings. The bottom plate 101 has a limiting protrusion 104 at its lower part that cooperates with the material boxes, dividing the interior of the hopper 1 into multiple material box slots, into which the material boxes 2 are inserted. Simultaneously, a limiting support plate 105 is also provided on the outer side of one of the side plates 102, and material boxes 2 are also mounted on the limiting support plate 105. Multiple material boxes work together to collect qualified products, NG products, and products that have not completed inspection during the process.

[0026] Please continue reading Figure 2 and Figure 3 The upper part of the hopper 1 has a notch on the side near the connecting frame 3, so that when the material box 2 is inserted into the hopper 1, the front end of the material box 2 extends to the lower part of the disc 5. Through the notch on one side of the hopper 1, the material box 2 is exposed. In this way, the outer edge of the disc 5 can be located above the material box 2 during operation, ensuring that each component is blown into the corresponding material box 2 by the air nozzle. In addition, the hopper 1 has a limiting stop bar 6 on the side near the connecting frame 3, which is used to limit the depth of the material box 2 inserted into the hopper 1, so that the material box 2 is inserted into the hopper 1 to reach a uniform position, avoiding the phenomenon of components scattering due to improper positioning.

[0027] Please continue reading Figure 2 The L-shaped arm 303 includes a horizontal arm 3031 and a vertical arm 3032. Both the horizontal arm 3031 and the vertical arm 3032 are provided with straight grooves. The fixing frame 302 is provided with bolt holes. The horizontal arm 3031 is bolted to the fixing frame 302, and the extension length of the horizontal arm 3031 is adjusted by the straight groove on the horizontal arm 3031. The connection between the horizontal arm 3031 and the vertical arm 3032 is provided with a groove and bolt holes. The vertical arm 3032 is stuck in the groove and is connected to the horizontal arm 3031 by bolts. The vertical height of the vertical arm 3032 is adjusted by the straight groove on the vertical arm 3032. The bolts are fixed in the corresponding straight grooves. When it is necessary to adjust the extension length of the horizontal arm 3031 or the vertical height of the vertical arm 3032, the bolts in the corresponding straight grooves are loosened. This allows the corresponding horizontal arm 3031 or vertical arm 3032 to be pulled. After adjustment, the bolts are tightened to complete the fixation. The lower part of the vertical arm 3032 is provided with an air nozzle 4.

[0028] Please continue to participate. Figure 2The mounting bracket 302 also includes a connecting arm 7, which has multiple sections connected by bolts. The connecting arm 7 also has straight grooves, with the connecting bolts positioned within the corresponding grooves. An air nozzle 4 and a scraper 8 are connected to the connecting arm 7. The air nozzle 4 blows air towards the material box 2 on the limiting support plate 105, blowing the original parts into the material box 2 on the limiting support plate 105. The scraper 8 scrapes any missed original parts from the disc into the material box 2. The mounting bracket 302 also includes an extension arm 9, on which a motor 10 is fixed. A brush 11 is connected to the head of the motor 10, contacting the disc to clean it and prevent unclean disc surfaces from interfering with photographic inspection.

[0029] The specific working principle is as follows: Please refer to the following for detailed usage. Figure 4 A motor is installed at the lower part of the disc 5 to drive the disc 5 to rotate. A feeding machine 12, a guiding mechanism 13, several camera detection modules 14, and the air-blowing classification and collection device proposed in this utility model are installed sequentially along the rotation direction on the outer edge of the disc 5. There are multiple material boxes 2, which respectively accept qualified products, unqualified products, and NG products. The feeding machine 12 is used to place the components on the disc 5 and adjust their position through the guiding mechanism. Then, the components are detected sequentially by multiple camera detection modules through the rotation of the disc. According to the detection results, the corresponding products are blown into the corresponding material boxes by the control system. The air nozzle is connected to an external compressed air part to provide an air source. When the disc 5 needs to be replaced, the flip fixing bracket 302 makes the air nozzle part move away from the upper part of the disc 5 without disassembling the whole, making the replacement work simpler.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
