[0035] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: like Figure 1-6 As shown, the ALS (Ambient Light Sensor) hole appearance automatic visual inspection system includes a fixed bracket 1, a visual inspection module 2, a glass placement platform 3, and a buffer placement rack 4. The visual inspection module 2 and the fixed bracket 1 are fixedly connected. The glass placement platform 3 is located below the fixed bracket 1, and the buffer placement rack 4 is used to place glass that fails the inspection. In this embodiment, the glass to be inspected is placed on the glass platform. The visual inspection module acquires images of the ALS holes in the glass and inspects the appearance of the ALS holes. If the inspection is passed and there are no defects, the glass proceeds to the next process. If the inspection fails and there are defects, the glass that fails the inspection is picked up by a suction device and placed on the buffer placement rack, where it is handed over to the corresponding personnel for rework. This achieves automatic inspection of the appearance of glass ALS holes, effectively reducing labor costs and improving inspection efficiency. Of course, it is not limited to this; any other system capable of automatically inspecting the appearance of glass ALS holes can be used.

[0036] Specifically, such as Figure 6 As shown, the visual inspection module 2 includes a visual acquisition camera 21 and an image processing unit 22, which are connected. In this embodiment, the visual acquisition camera acquires images of the glass, and the image processing unit analyzes in real time whether the glass has defects using a built-in defect recognition algorithm. Glass without defects proceeds to the next process, while glass with defects is picked up by a suction cup and placed on a buffer rack for rework by the relevant personnel; thus, the automatic inspection of the appearance of the ALS holes in the glass is completed. Of course, it is not limited to this; other methods capable of identifying defects can also be used.

[0037] Specifically, such as Figure 5 As shown, the buffer rack 4 is equipped with placement slots 41 for placing glass that fails the inspection. In this embodiment, the number of placement slots is 20. By increasing the number of placement slots, the rack can accommodate more glass that fails the inspection, effectively reducing the number of times workers need to retrieve the rack and improving production efficiency. Of course, it is not limited to this; any other method that can increase the number of glass that can be placed can be used.

[0038] Specifically, such as Figure 3As shown, a longitudinal adjustment component 11 is provided between the fixed bracket 1 and the vision inspection module 2. The vision inspection module 2 is fixedly connected to the fixed bracket 1 through the longitudinal adjustment component 11. In this embodiment, the vertical adjustment component drives the vision inspection module to adjust its vertical position, allowing the height of the vision inspection module to be adjusted according to the differences in glass, thus adapting to the inspection needs of different products. Of course, it is not limited to this; any other component capable of adjusting the vertical position of the vision inspection module can be used.

[0039] Specifically, the longitudinal adjustment assembly 11 includes a fixed plate 111, an adjusting rod 112, an adjusting block 113, and an adjusting hole 114.

The adjusting block 113 is provided with an adjusting protrusion 115, and the adjusting block 113 is connected to the adjusting hole 114 through the adjusting protrusion 115. In this embodiment, by rotating the adjusting rod, the adjusting block is driven to move up and down within the adjusting hole, thereby realizing the up and down movement of the adjusting block, and thus realizing the vertical position adjustment of the visual inspection module. Of course, it is not limited to this; any other assembly capable of realizing the vertical position adjustment of the visual inspection module can be used.

[0040] Specifically, such as Figure 2 As shown, a planar adjustment component 12 is provided between the fixed bracket 1 and the longitudinal adjustment component 11, and the longitudinal adjustment component 11 is connected to the fixed bracket 1 through the planar adjustment component 12. In this embodiment, the position adjustment of the vision detection module is achieved by moving the longitudinal adjustment component through the planar adjustment component. Of course, it is not limited to this; other components capable of achieving position adjustment of the vision detection module can be used.

[0041] Specifically, the planar adjustment assembly 12 includes a slide rail 121, a sliding block 122, a mounting plate 123, and a planar lead screw assembly 124. The slide rail 121 is fixedly connected to the fixed bracket 1. The mounting plate 123 is slidably connected to the slide rail 121 via the sliding block 122. One end of the planar lead screw assembly 124 is fixedly connected to the mounting plate 123, and the other end of the planar lead screw assembly 124 is fixedly connected to the fixed bracket 1. In this embodiment, the rotation of the planar lead screw assembly drives the sliding block to move on the slide rail. The sliding block drives the mounting plate to move, and the mounting plate drives the longitudinal adjustment assembly and the vision detection module to move, thereby realizing the position adjustment of the vision detection module. Of course, it is not limited to this; any other assembly capable of adjusting the position of the vision detection module can be used.

[0042] Specifically, such as Figure 4As shown, the glass placement platform 3 has a perforated structure 31. In this embodiment, a light source is typically located below the perforated structure. The perforated structure ensures light transmission through the ALS aperture of the glass, effectively improving detection efficiency and enhancing the compatibility of the glass placement platform to accommodate different products. Of course, other methods that ensure light transmission through the ALS aperture of the glass can also be used.

[0043] Specifically, such as Figure 5 As shown, the cache placement rack 4 is also equipped with a transmission component 5, and the cache placement rack 4 and the transmission component 5 are connected. In this embodiment, the transmission component drives the cache placement rack to achieve up-and-down movement. Of course, it is not limited to this; any other component capable of achieving up-and-down movement of the cache placement rack can be used.

[0044] Specifically, the transmission assembly 5 includes a transmission mounting bracket 51, a transmission screw 52, ​​a transmission block 53, a placement rack platform 54, and a transmission motor 55. The transmission screw 52 is connected to the transmission mounting bracket 51, the transmission block 53 is connected to the transmission screw 52, ​​the placement rack platform 54 is fixedly connected to the transmission block 53, the transmission motor 55 is connected to the transmission screw 52, ​​the transmission motor 55 is fixedly connected to the transmission mounting bracket 51, and the placement rack platform 54 is connected to the buffer placement rack 4. In this embodiment, the transmission motor drives the transmission screw to rotate, the transmission screw drives the transmission block to move up and down, and the transmission block drives the placement rack platform to move up and down, thereby realizing the up and down transmission of the buffer placement rack. Of course, it is not limited to this; any other device capable of realizing the up and down transmission of the buffer placement rack can be used.

[0045] Working principle: During use, the vision acquisition camera is adjusted above the ALS hole of the glass using the longitudinal adjustment component and the plane adjustment component. The glass to be inspected is fed to the glass placement platform, which performs compensation and precise positioning of the glass. Subsequently, the vision acquisition camera acquires images, and the image processing unit uses defect recognition algorithms to identify whether there are defects in the appearance of the ALS hole of the glass. If the inspection is passed and there are no defects, it proceeds to the next process. If the inspection fails and there are defects, the glass that fails the inspection is picked up by the material suction plate and placed on the buffer placement rack, and then handed over to the corresponding personnel for rework. This realizes the automatic inspection of the appearance of the ALS hole of the glass.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
