Description

Technical Field

[0001] This utility model relates to the technical field of screen testing mechanisms, specifically to a screen bonding and alignment testing mechanism that enables automatic type changing. Background Technology

[0002] Currently, in screen manufacturing lamination processes, the bonding of the CG cover (glass protective cover of the screen) and the Panel (image display panel of the screen) both use a visual alignment guidance method. A camera is used to collect image position information of the CG cover and the Panel, and the two images are superimposed to calculate the gap around the perimeter when the two products are bonded. The calculation results are given to the micro-motion platform, which is driven to move in the XY direction and angle to compensate for the position in advance. Then, the two products are joined together by pressure to achieve the bonding process and ensure that the perimeter gap of the two bonded products is within the accuracy tolerance requirements.

[0003] Currently available visual guidance methods often only compensate for products of a specific size or model during production. Switching between product sizes or models requires recalibrating parameters, necessitating significant time and experienced personnel. Furthermore, for excessively large products, multiple camera movements are required to capture images from different locations for stitching, leading to reduced production speed and significant fluctuations in accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a screen bonding and alignment detection mechanism that enables automatic type changing, thereby solving at least one of the aforementioned problems in the prior art.

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

[0006] A screen bonding alignment detection mechanism for automatic type changing includes an upper camera adjustment assembly. The upper camera adjustment assembly includes a bracket, a basic X-axis moving module, a first Y-axis moving plate, and a second Y-axis moving plate. The basic X-axis moving module is mounted on the bracket, and a bottom moving plate is provided on the basic X-axis moving module. A slide rail is provided on one side of the bottom moving plate, and the first Y-axis moving module and the second Y-axis moving module are respectively provided on the other side.

[0007] One end of the first Y-axis moving plate is slidably engaged with the slide rail, and the other end of the first Y-axis moving plate is disposed on the slide base of the first Y-axis moving module. One end of the second Y-axis moving plate is slidably engaged with the slide rail, and the other end of the second Y-axis moving plate is disposed on the slide base of the second Y-axis moving module.

[0008] A first camera is provided on the first Y-axis moving plate, a first X-axis moving module is provided on the first Y-axis moving plate, a second camera is provided on the first X-axis moving module, and the first camera and the second camera are arranged side by side along the X direction;

[0009] The second Y-axis moving plate is equipped with a third camera, the second Y-axis moving plate is equipped with a second X-axis moving module, and the second X-axis moving module is equipped with a fourth camera. The third camera and the fourth camera are arranged side by side along the X direction.

[0010] In this technical solution, the basic X-axis moving module drives the first camera, second camera, third camera and fourth camera to move together along the X direction, which can compensate for the differences in the X direction when different products are received, and ensure that the reference center point is consistent for each photo.

[0011] The first Y-axis moving module carries the first camera and the second camera. The first camera and the second camera share the first Y-axis moving module. For products of different lengths and sizes, the main adjustment is to change the shooting position of the first camera and the second camera relative to the center point of the product in the Y direction (the product length direction). Within the compatibility range of automatic changeover design, the position of the first width side of the product in the Y direction is changed by the moving module, which can switch the shooting position of the corresponding product at any time to ensure that the first camera and the second camera always correspond to a fixed shooting area on the first width side of the product, regardless of the size of the product.

[0012] The second Y-axis moving module carries the third and fourth cameras. The third and fourth cameras share the second Y-axis moving module. For products of different lengths and sizes, the main adjustment is to change the shooting position of the third and fourth cameras relative to the center point of the product in the Y direction (the product length direction). Within the compatibility range of automatic changeover design, the position of the second width side of the product in the Y direction is changed by this moving module, which can switch the shooting position of the corresponding product at any time to ensure that the third and fourth cameras always correspond to a fixed shooting area on the second width side of the product, regardless of the product size.

[0013] The first X-axis moving module carries the second camera. For products of different widths, the main adjustment is to change the position of the second camera relative to the center point of the product in the X direction (product width direction). Within the compatibility range of automatic changeover design, the position of the middle part of the first width side of the product (circular hole position) in the X direction is changed by the moving module. The corresponding product shooting position can be switched at any time to ensure that the second camera always corresponds to the fixed shooting and acquisition area of ​​the middle part of the first width side of the product (circular hole position) under any product size.

[0014] The fourth camera is mounted on the second X-axis moving module. For products of different widths, the main adjustment is to change the position of the fourth camera relative to the center point of the product in the X direction (product width direction). Within the compatibility range of automatic changeover design, the position of the middle part of the second width side of the product (circular hole position) in the X direction is changed by the moving module. The corresponding product shooting position can be switched at any time to ensure that the fourth camera always corresponds to the fixed shooting and acquisition area of ​​the middle part of the second width side of the product (circular hole position) under any product size.

[0015] In summary, this technical solution increases the number of image acquisition cameras on the panel from the traditional two cameras to four cameras. At the same time, it adds a set of Y-axis moving modules and X-axis moving modules, which can capture images of the four corners or four arbitrary areas of the product at the same time, completing image acquisition in one go, thus improving image acquisition efficiency. Moreover, the image acquisition area of ​​the camera can be automatically adjusted according to different product sizes through the moving modules, which greatly reduces changeover and debugging time and labor costs.

[0016] Furthermore, it also includes a lower camera adjustment component, which includes a bottom Y-axis moving module. The bottom Y-axis moving module is provided with a bottom moving platform. The bottom moving platform is provided with a first bottom X-axis moving module and a second bottom X-axis moving module. A bottom first camera is provided on a first slide of the first bottom X-axis moving module, and a bottom second camera is provided on a second slide of the second bottom X-axis moving module. The bottom first camera and the bottom second camera are arranged side by side along the X direction.

[0017] The bottom Y-axis moving module drives the bottom first camera and bottom second camera to move together along the Y-axis, which can compensate for the differences in the Y-axis when different products are received, and ensure that the reference center point is consistent for each photo.

[0018] The first bottom X-axis moving module carries the first bottom camera, and the second bottom X-axis moving module carries the second bottom camera. For products of different widths, the main adjustment is to change the shooting position of the first bottom camera and the second bottom camera relative to the center point of the product in the X direction (product width direction). Within the compatibility range of automatic changeover design, the position of the two shooting points on the product width side in the X direction is changed by the moving module, which can switch the shooting position of the corresponding product at any time, ensuring that the first bottom camera and the second bottom camera always correspond to two fixed shooting and acquisition areas on the product width side under any product size.

[0019] This technical solution sets up upper and lower camera adjustment mechanisms for the CG cover plate and the panel respectively. The bottom first camera and bottom second camera are responsible for collecting image position information of the CG cover plate, while the first, second, third and fourth cameras are responsible for collecting image position information of the panel. This facilitates the subsequent system to calculate the image information, calculate the positional deviation compensation of the two products, and perform positional correction processing in advance, so that the bonding accuracy of the products after bonding meets the requirements.

[0020] Furthermore, the first slide is provided with a first XYZ fine-tuning slide, the bottom first camera is disposed on the first XYZ fine-tuning slide, the second slide is provided with a second XYZ fine-tuning slide, and the bottom second camera is disposed on the second XYZ fine-tuning slide.

[0021] The XYZ-axis fine-tuning slide allows for subtle adjustments to the camera's X, Y, and Z positions within the travel space, resulting in more precise shooting positions and imaging effects.

[0022] Furthermore, in order to improve the stability of the movement of the bottom first camera and the bottom second camera, a bottom slide rail is provided on the bottom moving platform extending along the X direction, and the first slide platform and the second slide platform slide in cooperation with the bottom slide rail through a slider.

[0023] Furthermore, to facilitate the installation of the bottom light source, bottom light source mounting brackets are provided at both ends of the bottom moving platform, and the bottom light source mounting brackets are used to install the bottom light source.

[0024] Furthermore, to facilitate the installation of the top light source, both ends of the first Y-axis moving plate and the second Y-axis moving plate are provided with top light source brackets, which are used to install the top light source.

[0025] Furthermore, to facilitate the routing of the lines connected to the camera, the first Y-axis moving plate and the second Y-axis moving plate are respectively provided with a first outgoing pipe and a second outgoing pipe.

[0026] The beneficial effects of this utility model are as follows: In this technical solution, the basic X-direction moving module drives the first camera, the second camera, the third camera and the fourth camera to move as a whole along the X direction, which can compensate for the differences in the X direction when different products are received, and ensure that the reference center point is consistent for each photo.

[0027] The first Y-axis moving module carries the first camera and the second camera. The first camera and the second camera share the first Y-axis moving module. For products of different lengths and sizes, the main adjustment is to change the shooting position of the first camera and the second camera relative to the center point of the product in the Y direction (the product length direction). Within the compatibility range of automatic changeover design, the position of the first width side of the product in the Y direction is changed by the moving module, which can switch the shooting position of the corresponding product at any time to ensure that the first camera and the second camera always correspond to a fixed shooting area on the first width side of the product, regardless of the size of the product.

[0028] The second Y-axis moving module carries the third and fourth cameras. The third and fourth cameras share the second Y-axis moving module. For products of different lengths and sizes, the main adjustment is to change the shooting position of the third and fourth cameras relative to the center point of the product in the Y direction (the product length direction). Within the compatibility range of automatic changeover design, the position of the second width side of the product in the Y direction is changed by this moving module, which can switch the shooting position of the corresponding product at any time to ensure that the third and fourth cameras always correspond to a fixed shooting area on the second width side of the product, regardless of the product size.

[0029] The first X-axis moving module carries the second camera. For products of different widths, the main adjustment is to change the position of the second camera relative to the center point of the product in the X direction (product width direction). Within the compatibility range of automatic changeover design, the position of the middle part of the first width side of the product (circular hole position) in the X direction is changed by the moving module. The corresponding product shooting position can be switched at any time to ensure that the second camera always corresponds to the fixed shooting and acquisition area of ​​the middle part of the first width side of the product (circular hole position) under any product size.

[0030] The fourth camera is mounted on the second X-axis moving module. For products of different widths, the main adjustment is to change the position of the fourth camera relative to the center point of the product in the X direction (product width direction). Within the compatibility range of automatic changeover design, the position of the middle part of the second width side of the product (circular hole position) in the X direction is changed by the moving module. The corresponding product shooting position can be switched at any time to ensure that the fourth camera always corresponds to the fixed shooting and acquisition area of ​​the middle part of the second width side of the product (circular hole position) under any product size.

[0031] In summary, this technical solution increases the number of image acquisition cameras on the panel from the traditional two cameras to four cameras. At the same time, it adds a set of Y-axis moving modules and X-axis moving modules, which can capture images of the four corners or four arbitrary areas of the product at the same time, completing image acquisition in one go, thus improving image acquisition efficiency. Moreover, the image acquisition area of ​​the camera can be automatically adjusted according to different product sizes through the moving modules, which greatly reduces changeover and debugging time and labor costs.

For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0040] Example 1:

[0041] like Figures 1-6As shown, this embodiment provides a screen bonding alignment detection mechanism for automatic type changing, including an upper camera adjustment component.

The basic X-axis moving module 2 is mounted on the bracket 1. A bottom moving plate 5 is provided on the basic X-axis moving module 2. A slide rail 6 is provided on one side of the bottom moving plate 5, and a first Y-axis moving module 7 and a second Y-axis moving module 8 are respectively provided on the other side.

[0042] One end of the first Y-axis moving plate 3 is slidably engaged with the slide rail 6, and the other end of the first Y-axis moving plate 3 is set on the slide of the first Y-axis moving module 7. One end of the second Y-axis moving plate 4 is slidably engaged with the slide rail 6, and the other end of the second Y-axis moving plate 4 is set on the slide of the second Y-axis moving module 8.

[0043] A first camera 9 is provided on the first Y-axis moving plate 3, a first X-axis moving module 10 is provided on the first Y-axis moving plate 3, and a second camera 11 is provided on the first X-axis moving module 10. The first camera 9 and the second camera 11 are arranged side by side along the X direction.

[0044] The second Y-axis moving plate 4 is equipped with a third camera 12, the second Y-axis moving plate 4 is equipped with a second X-axis moving module 13, and the second X-axis moving module 13 is equipped with a fourth camera 14. The third camera 12 and the fourth camera 14 are arranged side by side along the X direction.

[0045] In this technical solution, the basic X-axis moving module 2 drives the first camera 9, the second camera 11, the third camera 12 and the fourth camera 14 to move together along the X-axis, which can compensate for the differences in the X-axis when different products 30 are received, and ensure that the reference center point is consistent for each photo.

[0046] The first Y-axis moving module 7 carries the first camera 9 and the second camera 11. The first camera 9 and the second camera 11 share the first Y-axis moving module 7. For products 30 of different lengths and sizes, the main adjustment is to change the shooting position of the first camera 9 and the second camera 11 relative to the center point of the product 30 in the Y direction (the length direction of the product 30). Within the compatibility range of the automatic change design, the position change of the first width side 31 of the product 30 in the Y direction is followed by the moving module. The shooting position of the corresponding product 30 can be switched at any time to ensure that the first camera 9 and the second camera 11 always correspond to a fixed shooting area on the first width side 31 of the product 30 under any size of the product 30.

[0047] The second Y-axis moving module 8 carries the third camera 12 and the fourth camera 14. The third camera 12 and the fourth camera 14 share the second Y-axis moving module 8. For products 30 of different lengths and sizes, the main adjustment is to change the shooting position of the third camera 12 and the fourth camera 14 relative to the center point of the product 30 in the Y direction (the length direction of the product 30). Within the compatibility range of the automatic changeover design, the position change of the second width side 32 of the product 30 in the Y direction is followed by the moving module. The shooting position of the corresponding product 30 can be switched at any time to ensure that the third camera 12 and the fourth camera 14 always correspond to a fixed shooting area on the second width side 32 of the product 30 under any size of the product 30.

[0048] The first X-axis moving module 10 carries the second camera 11. For products 30 of different widths, the main adjustment is to change the position of the second camera 11 relative to the center point of the product 30 in the X direction (the width direction of the product 30). Within the compatibility range of the automatic changeover design, the position change of the middle part of the first width side 31 of the product 30 (the position of the circular hole 33) in the X direction is followed by the moving module. The corresponding product 30 shooting position can be switched at any time to ensure that the second camera 11 always corresponds to the fixed shooting and acquisition area of ​​the middle part of the first width side 31 of the product 30 (the position of the circular hole 33) under any size of the product 30.

[0049] The fourth camera 14 is mounted on the second X-axis moving module 13. For products 30 of different widths, the main adjustment is to change the position of the fourth camera 14 relative to the center point of the product 30 in the X direction (the width direction of the product 30). Within the compatibility range of the automatic changeover design, the position of the middle part of the second width side 32 of the product 30 (the position of the circular hole 33) in the X direction is changed by the moving module.

[0050] In summary, this technical solution increases the number of image acquisition cameras on the panel from the traditional two cameras to four cameras. At the same time, it adds a set of Y-axis moving modules and X-axis moving modules, which can capture images of the four corners or four arbitrary areas of the product 30 at one time, completing image acquisition in one go, thus improving image acquisition efficiency. Moreover, the image acquisition area of ​​the camera can be automatically adjusted according to different product 30 sizes through the moving modules, which greatly reduces changeover and debugging time and labor costs.

[0051] Example 2:

[0052] This embodiment is an optimization based on the above embodiment 1.

[0053] It also includes a lower camera adjustment assembly, which includes a bottom Y-axis moving module 15, a bottom moving platform 16 on the bottom Y-axis moving module 15, a first bottom X-axis moving module 17 and a second bottom X-axis moving module 18 on the bottom moving platform 16, a bottom first camera 19 on the first slide of the first bottom X-axis moving module 17, and a bottom second camera 20 on the second slide of the second bottom X-axis moving module 18. The bottom first camera 19 and the bottom second camera 20 are arranged side by side along the X direction.

[0054] The bottom Y-axis moving module 15 drives the bottom first camera 19 and the bottom second camera 20 to move along the Y-axis as a whole, which can compensate for the differences in the Y-axis when different products 30 are received, and ensure that the reference center point is consistent for each photo.

[0055] The first bottom X-axis moving module 17 carries the first bottom camera 19, and the second bottom X-axis moving module 18 carries the second bottom camera 20. For products 30 with different widths, the main adjustment is to change the shooting position of the first bottom camera 19 and the second bottom camera 20 relative to the center point of the product 30 in the X direction (the width direction of the product 30). Within the compatibility range of automatic changeover design, the position change of the two shooting points on the width side of the product 30 in the X direction is followed by the moving module. The corresponding shooting position of the product 30 can be switched at any time to ensure that the first bottom camera 19 and the second bottom camera 20 always correspond to two fixed shooting areas on the width side of the product 30 under any size of the product 30.

[0056] This technical solution sets up upper and lower camera adjustment mechanisms for the CG cover plate and the Panel respectively. The bottom first camera 19 and bottom second camera 20 are responsible for collecting image position information of the CG cover plate, while the first camera 9, second camera 11, third camera 12 and fourth camera 14 are responsible for collecting image position information of the Panel. This facilitates the subsequent system to calculate the image information, calculate the positional deviation compensation of the two products 30, and perform positional correction processing in advance, so that the bonding accuracy of the products 30 after bonding meets the requirements.

[0057] It should be noted that the existing two bonding stations sharing a single bonding column may cause resonance, resulting in visual pixel jitter and blurry images. In this technical solution, the lower camera adjustment component and the upper camera adjustment component are completely isolated. Four upper cameras (first camera, second camera, third camera, and fourth camera) are supported by an independent bracket 1. The upper cameras are not affected by the lower camera adjustment component when acquiring images.

[0058] Example 3:

[0059] This embodiment is an optimization based on the above embodiment 2.

[0060] The first slide is provided with a first XYZ fine-tuning slide 21, and the bottom first camera 19 is set on the first XYZ fine-tuning slide 21. The second slide is provided with a second XYZ fine-tuning slide 22, and the bottom second camera 20 is set on the second XYZ fine-tuning slide 22.

[0061] The XYZ-axis fine-tuning slide allows for subtle adjustments to the camera's X, Y, and Z positions within the travel space, resulting in more precise shooting positions and imaging effects.

[0062] Example 4:

[0063] This embodiment is an optimization based on the above embodiment 3.

[0064] To improve the smoothness of the movement of the bottom first camera 19 and the bottom second camera 20, a bottom slide rail 23 is provided on the bottom moving platform 16 extending along the X direction. The first slide and the second slide are slidably engaged with the bottom slide rail 23 by a slider 24.

[0065] Example 5:

[0067] To facilitate the installation of the bottom light source, bottom light source mounting brackets 25 are provided at both ends of the bottom moving platform 16. The bottom light source mounting brackets 25 are used to install the bottom light source.

[0068] Example 6:

[0069] This embodiment is an optimization based on the above embodiment 1.

[0070] To facilitate the installation of the top light source 27, both ends of the first Y-axis movable plate 3 and the second Y-axis movable plate 4 are provided with top light source brackets 26, which are used to install the top light source 27.

[0071] Example 7:

[0072] This embodiment is an optimization based on the above embodiment 1.

[0073] To facilitate the routing of the cable connected to the camera, the first Y-axis movable plate 3 and the second Y-axis movable plate 4 are respectively provided with a first cable outlet pipe 28 and a second cable outlet pipe 29.

[0074] For instructions on how to take photos using the CG panel, please refer to Figure 5.

[0075] The bottom first camera 19 and the bottom second camera 20 take pictures of the VA area and the round hole at the corner of the CG panel from bottom to top. After taking pictures, they move to take pictures of the other corner VA area on the same long side of the CG panel. For products without round holes, the camera 30 moves to take pictures of the four corner VA areas of the CG panel.

[0076] For instructions on how to take a picture using the panel, please refer to Figure 6:

[0077] The first camera 9, the second camera 11, the third camera 12, and the fourth camera 14 take pictures of the two corner AA areas and the round hole of the panel from top to bottom. For products without round holes, the third camera takes pictures of the four corner AA areas of the panel.

[0078] This technical solution allows for the pre-setting of photo-taking positions for products 30 of different sizes. After the device acquires information about the product 30, it automatically switches to the photo-taking position corresponding to the model, achieving the purpose of one-click model change.
