Description

Technical Field

[0001] This utility model relates to the technical field of AOI appearance inspection equipment, and in particular to an AOI appearance inspection equipment for diffuser sheets. Background Technology

[0002] With the advancement of technology, LCDs are becoming increasingly high-definition, thinner, full-screen, and with narrow bezels. Currently, inspection mainly relies on manual labor. However, the variability of manual labor increases the risk of misjudgment and cost overruns. Therefore, AOI (Area Scanning) equipment is needed. AOI equipment replaces the limitations of the human eye through "high-precision imaging + algorithm decision-making," becoming a core technology node for ensuring optical uniformity and reliability. High-precision imaging requires the use of area scan cameras. An area scan camera is an industrial imaging device with photosensitive chips arranged in a rectangular matrix, which directly acquires two-dimensional image information through a single exposure.

[0003] In the existing technology, the height of the area scan camera is not easy to adjust after installation, which cannot meet different usage requirements. Therefore, we propose an AOI appearance inspection device for diffuser sheets to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of area array cameras, such as the inconvenience of adjusting their height after installation and their inability to meet different usage requirements, by proposing an AOI appearance inspection device for diffuser sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An AOI appearance inspection device for diffuser sheets includes:

[0007] Conveyor rack;

[0008] Two support plates are fixedly installed on both sides of the conveyor frame; a top plate is fixedly installed on one side of both support plates.

[0009] A rectangular vertical hole is provided on the top plate. A mounting base is slidably installed in the rectangular vertical hole, and a field scan camera is installed at the bottom of the mounting base.

[0010] The lifting mechanism, mounted on the support plate, is used to lift the mounting base.

[0011] The T-block is fixedly installed on the area scan camera. The bottom of the mounting base has a T-slot with two openings. The T-block is snapped into the T-slot.

[0012] The limiting plate is fixedly installed at the bottom of the top plate and is used to limit the movement of the T-block.

[0013] Preferably, the lifting mechanism includes a push plate slidably mounted on one side of the support plate, a connecting plate fixedly mounted on the top of the push plate, and the bottom of the connecting plate fixedly connected to the top of the mounting base.

[0014] Preferably, a bearing is fixedly installed on one side of the support plate, and a screw is fixedly installed on the inner ring of the bearing, with the screw threadedly connected to the push plate.

[0015] Preferably, a rotating block is fixedly installed at the bottom of the screw, and the rotating block is located below the bearing.

[0016] Preferably, multiple drive rollers are rotatably mounted on the conveyor frame, and the same conveyor belt is driven onto the multiple drive rollers.

[0017] Preferably, a motor is fixedly installed on one side of the conveyor frame, and the output shaft of the motor is fixedly connected to one end of a transmission roller.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This solution involves inserting a T-block into a T-slot from the right side of the mounting base. Then, rotating the rotating block causes the screw to rotate, which in turn moves the push plate, which is threadedly connected to the screw, upward. The push plate then moves the connecting plate upward, which in turn moves the mounting base upward. The mounting base then moves the T-block upward, thereby moving the area scan camera upward and adjusting its height. When the T-block moves upward, its right side contacts the left side of the limiting plate, which confines the T-block within the T-slot, thus ensuring the stability of the area scan camera.

[0020] This utility model facilitates the installation of array cameras and allows for adjustment of the camera's height to meet different usage needs. Attached Figure Description

[0025] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments. Example 1

[0026] Reference Figures 1-3 An AOI appearance inspection device for diffuser sheets, comprising:

[0027] Conveyor frame 1;

[0028] Two support plates 5 are fixedly installed on both sides of the conveyor frame 1 respectively; a top plate 6 is fixedly installed on one side of the two support plates 5.

[0029] A rectangular vertical hole 7 is provided on the top plate 6. A mounting base 8 is slidably installed in the rectangular vertical hole 7. A field array camera 9 is installed at the bottom of the mounting base 8.

[0030] A lifting mechanism, located on the support plate 5, is used to lift the mounting base 8.

[0031] T-block 11 is fixedly installed on area array camera 9. The bottom of mounting base 8 is provided with T-slot 10, which has two openings. T-block 11 is snapped into T-slot 10.

[0032] The limiting plate 12 is fixedly installed at the bottom of the top plate 6 and is used to limit the T-block 11.

[0033] In this embodiment, the lifting mechanism includes a push plate 14 that is slidably mounted on one side of the support plate 5, a connecting plate 13 that is fixedly mounted on the top of the push plate 14, and the bottom of the connecting plate 13 that is fixedly connected to the top of the mounting base 8.

[0034] In this embodiment, a bearing 15 is fixedly installed on one side of the support plate 5, and a screw 16 is fixedly installed on the inner ring of the bearing 15. The screw 16 is threadedly connected to the push plate 14.

[0035] In this embodiment, a rotating block 17 is fixedly installed at the bottom of the screw 16, and the rotating block 17 is located below the bearing 15.

[0036] In this embodiment, multiple drive rollers 2 are rotatably mounted on the conveyor frame 1, and the same conveyor belt 3 is driven and mounted on the multiple drive rollers 2.

[0037] In this embodiment, a motor 4 is fixedly installed on one side of the conveyor frame 1, and the output shaft of the motor 4 is fixedly connected to one end of a transmission roller 2.

[0038] In this embodiment, during use, the T-block 11 is inserted into the T-groove 10 from the right side of the mounting base 8. Then, the rotating block 17 is rotated, which drives the screw 16 to rotate, causing the push plate 14, which is threadedly connected to the screw 16, to move upward. The push plate 14 drives the connecting plate 13 to move upward, the connecting plate 13 drives the mounting base 8 to move upward, and the mounting base 8 drives the T-block 11 to move upward, thereby causing the area array camera 9 to move upward and adjust the height of the area array camera 9. When the T-block 11 moves upward, the right side of the T-block 11 contacts the left side of the limiting plate 12. The limiting plate 12 restricts the T-block 11 within the T-groove 10, thereby ensuring the stability of the area array camera 9. Example 2

[0039] The difference from Embodiment 1 is that: a base plate is provided below the conveyor frame 1, and multiple cylinders are fixedly installed on the top of the base plate. The output shaft of the cylinder is fixedly connected to the bottom of the conveyor frame 1, and the height of the conveyor frame 1 is adjusted by the cylinder.

[0040] The rest is the same as in Example 1.

[0041] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
