[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0032] like Figure 1-9 As shown, the present application provides a display BLU-AOI detection device, including: a first frame 1, a second frame 4 and a reflux conveying mechanism 5, a feed port 3 is opened on one side of the first frame 1, and a feed conveying mechanism 2 is installed on the first frame 1, a plug-in and pull-out mechanism 7 is installed at the bottom of the inner cavity of the first frame 1, and a plurality of detection cameras 10 are installed on the top of the inner cavity of the first frame 1, the second frame 4 is vertically arranged with the first frame 1, and a feed conveying mechanism 6 is installed on one side of the second frame 4, and the feed conveying mechanism 6 is arranged in the same direction as the feed conveying mechanism 2, the reflux conveying mechanism 5 is located on one side of the second frame 4, and the reflux conveying mechanism 5 extends to the inner cavity of the second frame 4; wherein, a cleaning mechanism 8 for cleaning the product is also installed on the feed conveying mechanism 2, and a transplanting mechanism 9 for transferring the product on the feed conveying mechanism 2 to the reflux conveying mechanism 5 is installed inside the second frame 4.

[0033] In this embodiment, this scheme is a device for performing AOI inspection on the display BLU. Specifically, the display BLU to be inspected is placed in the feed conveying mechanism 2 through the feed port 3, and the feed conveying mechanism 2 drives it to move. Then, the cleaning mechanism 8 is used to clean the surface of the display BLU to facilitate subsequent AOI inspection. The feed conveying mechanism 2 continues to drive it to move, so that the display BLU moves to the inspection location, and then the plug-in line mechanism 7 is used to establish a connection with the display BLU, and a plurality of inspection cameras 10 are used to perform defect inspection on the surface of the display BLU. When the inspection is qualified, the feed conveying mechanism 2 is used to convey the display BLU to the unloading conveying mechanism 6 for automatic unloading. Conversely, when the inspection is unqualified, the transplanting mechanism 9 is used to transfer the product on the feed conveying mechanism 2 to the reflux conveying mechanism 5 for unloading. The staff re-judges the display BLU. Through automated equipment and processes, there is no need for manual unloading, which reduces manual intervention and improves inspection speed and efficiency.

[0034] Among them, the feed conveying mechanism 2, the reflux conveying mechanism 5, and the unloading conveying mechanism 6 all adopt a roller-type transmission structure.

[0035] like Figure 5-6 As shown, the cleaning mechanism 8 includes a moving frame 81, which is fixed to the first frame 1 by means of bolts, a connecting seat 87 is installed at the bottom of the moving frame 81, a cleaning roller 88 is rotatably connected to the inner side of the connecting seat 87, a second motor 89 is installed on the outer wall of the connecting seat 87 by means of bolts, the output end of the second motor 89 is key-connected to the cleaning roller 88, a first cylinder 84 is installed on the top of the moving frame 81 by means of bolts, a connecting plate 85 is key-connected to the output end of the first cylinder 84, a pair of connecting columns 86 are installed at the bottom of the connecting plate 85, the connecting columns 86 pass through the moving frame 81 and are fixedly connected to the connecting seat 87, the cleaning mechanism 8 also includes a driving member 82 for driving the moving frame 81 to move along the conveying direction of the feed conveying mechanism 2, and the moving frame 81 is slidably connected to the top of the feed conveying mechanism 2.

[0036] In this embodiment, the cleaning roller 88 is controlled to rotate by the second motor 89, and the driving member 82 is used to control the movable frame 81 to slide on the top of the feeding conveying mechanism 2, so as to clean the surface of the product and facilitate the subsequent AOI inspection.

[0037] The connecting plate 85 is controlled to rise and fall by the first cylinder 84 , thereby controlling the height of the cleaning roller 88 , which is suitable for cleaning BLUs of displays with different thicknesses.

[0038] It should be noted that the driving member 82 can be driven by a motor screw to achieve the purpose of moving the movable frame 81 along the conveying direction of the feed conveying mechanism 2.

[0039] like Figure 7 As shown, the cleaning mechanism 8 also includes a clamping member 83 for positioning the product, the clamping member 83 includes a mounting frame 831, a pair of bases 834 and a power source for driving the pair of bases 834 to move in opposite directions or towards each other, the mounting frame 831 is installed on the feed conveying mechanism 2 by means of bolts, the pair of bases 834 are both slidably connected to the top of the mounting frame 831, and a plurality of clamping rods 835 are installed on the top of the pair of bases 834.

[0040] In this embodiment, a pair of bases 834 can be controlled by a power source to move toward each other, so that the clamping rod 835 can be used to clamp the display BLU on the top of the feeding and conveying mechanism 2 to ensure the stability of the display BLU during cleaning.

[0041] Among them, multiple clamping rods 835 are located in the gaps between adjacent rollers on the feed conveying mechanism 2, and the movement direction of a pair of bases 834 is the length direction of the roller, thereby ensuring that the clamping rods 835 can clamp the product smoothly.

[0042] It should be noted that a clamping member 83 is also provided on the feeding and conveying mechanism 2 and located at the detection location, which is mainly used for positioning during the display BLU detection process to improve the stability during the detection and plugging and unplugging processes.

[0043] like Figure 1-7 As shown, the power source includes a first motor 832 mounted on the side wall of the mounting frame 831 , the output end of the first motor 832 is keyed to a bidirectional screw rod 833 , and a pair of bases 834 are both installed with screw sleeves 836 that match the bidirectional screw rod 833 at the bottom.

[0044] In this embodiment, the first motor 832 is used to drive the bidirectional screw rod 833 to rotate, thereby driving a pair of first cylinders 84 to move in opposite directions or towards each other.

[0045] like Figure 8-9 As shown, the transplanting mechanism 9 includes a belt module 91, which is installed in the second frame 4. A slider 92 is slidably connected to the top of the belt module 91. A support plate 93 is provided on the top of the slider 92. A plurality of support rods 94 are installed on the top of the support plate 93. A second cylinder 95 is installed on the top of the slider 92. The output end of the second cylinder 95 is key-connected to the bottom of the support plate 93.

[0046] In this embodiment, when the product fails the inspection, the second cylinder 95 can be started to control the support plate 93 to rise, and the multiple support rods 94 can be driven to rise synchronously until the support rods 94 lift the product located on the top of the feed conveying mechanism 2, and then the slider 92 is controlled to move by the belt module 91 until the lifted product moves to the top of the reflux conveying mechanism 5, and finally the second cylinder 95 drives the support rods 94 to reset, so that the product is placed on the top of the reflux conveying mechanism 5, so that the product can be discharged smoothly.

[0047] It should be noted that the direction in which the belt module 91 drives the product to move is the length direction of the rollers in the feed conveying mechanism 2 and the reflux conveying mechanism 5. In addition, a reserved cavity is provided on the feed conveying mechanism 2 and the reflux conveying mechanism 5 to provide reserved space for the movement of the support rod 94 without obstructing its movement, thereby ensuring that the product is smoothly transferred to the top of the reflux conveying mechanism 5.

[0048] Working principle:

[0049] The display BLU to be inspected is placed in the feed conveying mechanism 2 through the feed port 3. The feed conveying mechanism 2 drives it to move. Then, the cleaning mechanism 8 is used to clean the surface of the display BLU to facilitate subsequent AOI inspection. The feed conveying mechanism 2 continues to drive it to move, so that the display BLU is moved to the inspection location. Then, the plug-in and unplug-wire mechanism 7 is used to establish a connection with the display BLU, and a plurality of inspection cameras 10 are used to inspect the surface of the display BLU for defects. When the inspection is qualified, the feed conveying mechanism 2 is used to transport the display BLU to the unloading conveying mechanism 6 for automatic unloading. On the contrary, when the inspection is unqualified, the transplanting mechanism 9 is used to transfer the product on the feed conveying mechanism 2 to the reflux conveying mechanism 5 for unloading, and the staff re-judges the display BLU.
