It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0021] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Combine the following Figures 1 to 6 The specific embodiments of the present invention are described in detail.

[0024] This embodiment provides an AOI device for degassing a display screen, comprising a frame 1, a backlight platform 2, a detection mechanism 3, a turning mechanism 4 and a transport mechanism 5.

[0025] Among them, the rack 1 is mainly used to provide hardware support for other components.

[0026] Specifically, the rack 1 of this embodiment includes a base 11, a support platform 12, a detection bracket 13 and a transport bracket 14. The support platform 12 is fixed on the base 11 and used to install the backlight platform 2. The detection bracket 13 and the transport bracket 14 are both fixed on the support platform 12 and used to install the detection mechanism 3 and the transport mechanism 5 respectively. The flip mechanism 4 is installed on the base 11. This arrangement can compensate for the height difference between different mechanisms, and the spatial layout is more reasonable.

[0027] Furthermore, in this embodiment, a plurality of fixing seats are provided below the base 11 . The fixing seats have the function of adjusting the height. The cooperation of the plurality of fixing seats can realize the leveling of the base 11 .

[0028] The backlight platform 2 is installed on the frame 1 and is used to place the product to be tested.

[0029] It is easy to understand that the backlight platform 2 is a mature structure in this field, and its main function is to illuminate the side of the product to be tested that is in contact with the backlight platform 2 to ensure the brightness of the field of view of visual inspection.

[0030] Specifically, in this embodiment, the backlight platform 2 is fixed to the middle of the support platform 12 , and a gap is reserved between the backlight platform 2 and the edge of the support platform 12 to install other components.

[0031] Among them, the detection mechanism 3 includes a detection frame 31, a visual component 32 and a light source component 33. The visual component 32 and the light source component 33 are both installed on the detection frame 31. The detection frame 31 is installed on the frame 1 and can be driven to translate along the Y direction so that the visual component 32 has a detection state located directly above the backlight platform 2 and an avoidance state away from the backlight platform 2.

[0032] It is easy to understand that when the visual component 32 is in the detection state, the product under test is detected, and when the visual component 32 is in the avoidance state, other mechanisms perform related actions directly above the backlight platform 2.

[0033] Specifically, two detection brackets 13 are provided, and the two detection brackets 13 are both fixed on the support platform 12 and are respectively located on both sides of the backlight platform 2 in the X direction, and the detection frame 31 is connected between the two detection brackets 13 .

[0034] Specifically, the visual component 32 of this embodiment includes four groups of cameras and lenses; in other embodiments, it can also be designed as three groups or five groups or other reasonable numbers according to the product size.

[0035] Specifically, the light source assembly 33 of this embodiment includes two strip lights, which are arranged along the X direction, and the two strip lights are both located below the visual assembly 32 and respectively located on both sides of the visual assembly 32 in the Y direction. When working, the two strip lights illuminate both sides of the product to be tested in the Y direction to ensure the brightness of the field of view.

[0036] Specifically, the detection mechanism 3 of this embodiment further includes a detection Y-direction drive pair 34 and a Y-direction guide rail 35, the fixed portion of the detection Y-direction drive pair 34 and the track of the Y-direction guide rail 35 are both fixed on the frame 1, and the detection frame 31 is fixed on the slider of the Y-direction guide rail 35 and connected to the moving portion of the detection Y-direction drive pair 34. When in motion, the detection Y-direction drive pair 34 drives the detection frame 31 to move so that the visual component 32 switches between the detection state and the avoidance state.

[0037] More specifically, the detection Y-axis driving pair 34 of the present embodiment is a linear module, and other embodiments may use a motor screw pair, an electric push rod or other commonly used linear power elements.

[0038] Furthermore, the detection mechanism 3 of this embodiment also includes a fine-tuning component 36, and the visual component 32 is installed on the detection frame 31 through the fine-tuning component 36. The fine-tuning component 36 is used to adjust the spatial position of the visual component 32. When the detection component is initially installed, its spatial position needs to be debugged according to the product. In this embodiment, the position of the visual component 32 in the X-axis, Y-axis and Z-axis directions can be slightly adjusted through the fine-tuning component 36, so that the visual component 32 can adapt to the detection of products of different specifications. The fine-tuning component 36 can adopt a sliding groove and a slider matching structure or a bar hole and a bolt matching structure or other commonly used position adjustment structures.

[0039] The flip mechanism 4 includes a flip drive 41 and a flip suction cup 42. The flip suction cup 42 is mounted on the rotating part of the flip drive 41 and the rotating axis of the flip drive 41 is arranged along the Y direction. The fixed part of the flip drive 41 is mounted on the frame 1 and can be driven to translate along the Y direction so that the flip suction cup 42 has a working state located directly above the backlight platform 2 and a reset state detached from the backlight platform 2. The fixed part of the flip drive 41 can also be driven to rise and fall along the Z direction so that the flip suction cup 42 can absorb the product. During operation, after the front detection of the product to be tested is completed, the visual component 32 moves to the avoidance state in the Y direction, and the flip suction cup 42 descends to absorb the product to be tested and rises, and then flips 180° through the flip drive 41 so that the back of the product to be tested faces upward, waiting for the cooperation of the conveying mechanism 5.

[0040] It is easy to understand that the flip suction cup 42 performs three actions when in working state: first, descending to absorb the product; second, flipping the product; third, docking with the transport suction cup 51 to transfer the product. When the flip suction cup 42 is in the reset state, it is mainly used to avoid other mechanisms from performing related actions directly above the backlight platform 2.

[0041] Specifically, the flip mechanism 4 of the present embodiment further includes a flip Y-direction drive pair 43 and a flip Z-direction drive pair 44, the fixed portion of the flip Y-direction drive pair 43 is fixed on the frame 1, the fixed portion of the flip Z-direction drive pair 44 is fixed on the moving portion of the flip Y-direction drive pair 43, and the fixed portion of the flip driving member 41 is fixed on the moving portion of the flip Z-direction drive pair 44. When in motion, the flip Y-direction drive pair 43 drives the flip Z-direction drive pair 44, the flip driving member 41 and the flip suction cup 42 to translate along the Y direction as a whole, and the flip Z-direction drive pair 44 drives the flip driving member 41 and the flip suction cup 42 to rise and fall along the Z direction as a whole, thereby realizing the Y-direction translation and Z-direction lifting of the fixed portion of the flip driving member 41.

[0042] More specifically, the flip Y-direction drive pair 43 of the present embodiment is a linear module, the flip Z-direction drive pair 44 is a linear motor, and the flip drive member 41 is a rotary cylinder; in other embodiments, the flip Y-direction drive pair 43 and the flip Z-direction drive pair 44 may also use a motor screw pair, an electric push rod or other commonly used linear power elements, and the flip drive member 41 may also use a rotary motor or other commonly used rotary power elements.

[0043] The transport mechanism 5 includes a transport suction cup 51, which is mounted on the frame 1 and can be driven to move in the X direction so that the transport suction cup 51 has an adsorption state located directly above the flip suction cup 42 and an avoidance state away from the flip suction cup 42. The transport suction cup 51 can also be driven to rise and fall in the Z direction so that the transport suction cup 51 can place the product on the backlight platform 2. During operation, after the product to be tested is turned upside down by the flip mechanism 4, the transport suction cup 51 moves in the X direction to the adsorption state, and then descends to adsorb the product to be tested. At the same time, the vacuum of the flip suction cup 42 fails, and the flip suction cup 42 moves in the Y direction to the reset state after it descends. Finally, the transport suction cup 51 continues to descend to place the product to be tested on the backlight platform 2.

[0044] Specifically, the transport bracket 14 is fixed on the support platform 12 and is located on one side of the backlight platform 2 in the Y direction, and the transport suction cup 51 is installed on the transport bracket 14 .

[0045] Specifically, the transport mechanism 5 of this embodiment further includes a transport X-direction drive pair 52 and a transport Z-direction drive pair 53, the fixed portion of the transport X-direction drive pair 52 is fixed to the frame 1, the fixed portion of the transport Z-direction drive pair 53 is fixed to the moving portion of the transport X-direction drive pair 52, and the transport suction cup 51 is fixed to the moving portion of the transport Z-direction drive pair 53. When in motion, the transport X-direction drive pair 52 drives the transport Z-direction drive pair 53 and the transport suction cup 51 to move in the X direction as a whole, and the transport Z-direction drive pair 53 drives the transport suction cup 51 to move in the Z direction, thereby realizing the X-direction movement and Z-direction movement of the transport suction cup 51.

[0046] More specifically, the transport X-axis drive pair 52 of this embodiment is a linear module, and the transport Z-axis drive pair 53 is a linear motor; in other embodiments, the transport X-axis drive pair 52 and the transport Z-axis drive pair 53 can also use a motor screw pair, an electric push rod or other commonly used linear power elements.

[0047] In addition, the AOI device of this embodiment further includes a turnover mechanism 6, which includes a turnover platform 61, which is mounted on the frame 1 and has a turnover state located on the side of the backlight platform 2X. When in operation, the upper process can place the incoming product on the turnover platform 61, and then transfer the incoming product to the backlight platform 2 through the conveying mechanism 5; after the inspection is completed, the product can also be transferred to the turnover platform 61 through the conveying mechanism 5 and transferred to the next process.

[0048] Furthermore, the turnover platform 61 of this embodiment is driven to move along the Y direction and has a loading state for docking with the previous process. When in operation, the turnover platform 61 first moves in the Y direction to the loading state to dock with the previous process, and then moves in the Y direction to the turnover state to wait for the transfer of the handling component.

[0049] Specifically, the turnover mechanism 6 of this embodiment further includes a turnover Y-direction drive pair 62 , a fixed portion of the turnover Y-direction drive pair 62 is fixed on the frame 1 , and a movable portion of the turnover Y-direction drive pair 62 is connected to the turnover platform 61 .

[0050] More specifically, the epicyclic Y-axis driving pair 62 of the present embodiment is a linear module; in other embodiments, the epicyclic Y-axis driving pair 62 may also adopt a motor screw pair, an electric push rod or other commonly used linear power elements.

[0051] Furthermore, the AOI device of this embodiment further includes a material unloading robot 7, which is mounted on the frame 1, and the turnover platform 61 also has a material unloading state for docking with the material unloading robot 7 by moving in the Y direction. When in operation, after the product to be tested is inspected, the product can be transported to the turnover platform 61 through the conveying mechanism 5, and then the turnover platform 61 moves in the Y direction to the material unloading state, and the material unloading robot 7 moves to transfer the product to the next process.

[0052] The working principle of the AOI equipment used for degassing the display screen in this embodiment is as follows: S1. The turnover platform 61 moves along the Y direction to the loading state, and the upper process places the incoming product on the turnover platform 61; S2. The turnover platform 61 moves along the Y direction to the turnover state, and the transport suction cup 51 transports the product to the backlight platform 2 through a combined movement in the Z and X directions; S3. The detection frame 31 moves along the Y direction so that the visual component 32 switches to the detection state, and the visual component 32 detects the front of the product to be tested; after the detection is completed, the detection frame 31 moves along the Y direction so that the visual component 32 switches to the avoidance state; S4.

The turnover platform 61 moves along the Y direction to the unloading state, and the unloading robot 7 transfers the product to the next process, and the operation of this process is completed.
