Description

Technical Field

[0001] This invention relates to the field of screen monitoring technology, specifically to a defoaming visual inspection device and method for OLED displays with anti-reflective white patches. Background Technology

[0002] OLED screens are widely used in mobile phones, televisions, laptops and other fields due to their excellent brightness, color and contrast. The production of OLED screens mainly involves the array segment, the vapor deposition and encapsulation segment and the module segment. Among them, in the module segment, bonding-inspection-debubbling forms a closed process loop, which to a certain extent determines the display quality of the OLED screen.

[0003] In the bubble detection process, a vision monitor is mainly used for image acquisition. Based on the detection results, a secondary bubble removal process is performed on the screen containing bubbles. For OLED flat screens, the vision monitor performs horizontal movement, while for OLED curved screens, the vision monitor needs to perform circular movement. To ensure the accuracy of image acquisition, the vision monitor needs to perform circular movement concentric with the center of the curved screen to maintain a predetermined distance between them. Currently, the curvature of mainstream OLED curved screens on the market is 1000R, 1500R, and 1800R. This means that when OLED curved screens of the same size with different curvatures are placed at the inspection station, their center heights are not consistent. To ensure detection accuracy, the existing technology compensates for the distance in the radial direction as the vision monitor moves. However, this distance compensation still cannot maintain a predetermined distance between the vision monitor and the curved screen at all times, resulting in image distortion and defocusing, which affects the detection accuracy. Summary of the Invention

[0017] As a further embodiment of the present invention: the fan-shaped guide is provided with three sets of arc-shaped parts, and the three sets of arc-shaped parts are respectively provided with a first guide groove, a second guide groove and a third guide groove. The circumferential radii of the first guide groove, the second guide groove and the third guide groove increase sequentially, and the first guide groove, the second guide groove and the third guide groove form the guide groove.

[0018] As a further embodiment of the present invention: the extrusion structure includes an electric telescopic rod fixedly installed on the sliding block, a pressure roller is rotatably installed on the actuating end of the electric telescopic rod, a convex shaft is connected to the rotating shaft of the pressure roller, and the convex shaft can roll within a limiting groove provided along the length direction of the sliding block;

[0019] The extrusion structure also includes a pressure receiving component connected to the telescopic shaft. The pressure receiving component cooperates with the pressure roller and can drive the telescopic shaft to move relative to the sliding block.

[0020] As a further embodiment of the present invention: the side of the pressure-bearing member is provided with a first extension and a second extension, and a through groove is formed in the middle of the second extension, the width of the through groove being greater than the width of the first extension.

This ensures that the center of the visual monitor's circular motion is concentric with the center of the curved screen, thereby maintaining a predetermined distance between the visual monitor and the curved screen during circular motion. This improves image acquisition accuracy and avoids image scaling distortion and defocusing.

[0033] By using clamping rollers, clamping parts, and pneumatic structures, the curved screen placed on the horizontal plate can be positioned. This ensures that the center of the curved screen is concentric with the center of the guide groove, so that the center of the circular motion of the vision monitor is concentric with the center of the curved screen to be inspected, thus improving the accuracy of image acquisition.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0048] Please see Figures 1-11In this embodiment of the invention, the defoaming visual inspection device for the OLED display screen with anti-reflective white blocks includes: an inspection machine 1, a rocker arm 6, an elastic telescopic component, a fan-shaped guide 16, and an extrusion structure.

[0049] The testing machine 1 is equipped with a horizontal plate 2 for supporting the OLED display screen;

[0050] The rocker arm 6 is rotatably mounted on the horizontal plate 2. A sliding block 7 is slidably mounted on the rocker arm 6 along its length. Two sets of obliquely placed visual monitors 25 are connected to the sliding block 7. Specifically, the visual monitors 25 are connected to the sliding block 7 through a bracket 24.

[0051] A drive device 3 is fixedly installed on the horizontal plate 2. A first gear 4 is connected to the output shaft of the drive device 3. The first gear 4 meshes with a second gear 5 connected to the rotating shaft of the rocker arm 6.

[0052] When the curved screen to be inspected is placed on the horizontal plate 2, the control drive device 3 is activated. At this time, the first gear 4 connected to its output shaft can rotate and drive the rocker arm 6 to swing through the meshing action with the second gear 5. During this process, the rocker arm 6 drives the vision monitor 25 to make circular motion through the sliding block 7 and the bracket 24, so that the vision monitor 25 can collect images of the curved screen in a circular motion, which improves the detection accuracy to a certain extent. Compared with the horizontal movement of the vision monitor 25 in the prior art, making the vision monitor 25 make circular motion can prevent the vision monitor 25 from causing problems such as image distortion and defocusing due to the change in distance between the two when collecting images at the edge of the curved screen.

[0053] It should be noted that because the aforementioned visual monitor 25 is tilted, it prevents white patches from appearing in the image due to reflections when acquiring image data, thus improving the stability of image acquisition.

[0054] Please see Figures 2-6 The rocker arm 6 is provided with a groove 601 at one end away from its rotation center, and the sliding block 7 is slidably installed in the groove 601.

[0055] The bottom of the sliding block 7 is fixedly installed with an abutment shaft 8, which abuts and is adapted to the support member 10 installed on the horizontal plate 2.

[0056] Multiple sets of the elastic telescopic components are provided and installed on the sliding block 7, and a guide roller 11 is rotatably installed at one end of the elastic telescopic components;

[0057] The fan-shaped guide 16 is fixedly installed on the horizontal plate 2. The fan-shaped guide 16 is provided with multiple sets of guide grooves with different radii. The guide grooves are adapted to the rolling of the guide roller 11.

[0058] In this embodiment, when the rocker arm 6 deflects to the end of its stroke, the abutment shaft 8 is in contact with the support member 10, ensuring that the sliding block 7 does not move in the slide groove 601. At the same time, each set of guide rollers 11 is in a corresponding state with the end of the corresponding guide groove. In use, the curved screen to be tested is first placed on the horizontal plate 2 and positioned. Then, according to the curvature of the curved screen to be tested, the corresponding guide roller 11 is inserted into the corresponding guide groove (the center of the guide groove is concentric with the center of the curved screen). When the rocker arm 6 deflects, the sliding block 7 can be displaced in the slide groove 601 with the cooperation of the guide roller 11 and the guide groove, and maintain a constant distance from the curved screen to be tested. At this time, when the vision monitor 25 follows the rocker arm 6 to make a circular motion, it can maintain a predetermined distance from the curved screen to be tested, so that the distance between the vision monitor 25 and the curved screen when collecting image data is more stable, thereby ensuring the accuracy of image detection and preventing the collected image from being distorted or out of focus.

[0059] Specifically, the elastic telescopic component includes a telescopic shaft 9 that slides through the sliding block 7, one end of the telescopic shaft 9 is provided with a limit ring 902, and the guide roller 11 is coaxially rotatably connected to the telescopic shaft 9;

[0060] The elastic telescopic assembly also includes a cylindrical spring 12 sleeved on the telescopic shaft 9, one end of the cylindrical spring 12 being connected to the sliding block 7 and the other end being connected to the end of the telescopic shaft 9;

[0061] The fan-shaped guide member 16 is provided with three sets of arc-shaped members, and the three sets of arc-shaped members are respectively provided with a first guide groove 1601, a second guide groove 1602 and a third guide groove 1603. The circumferential radii of the first guide groove 1601, the second guide groove 1602 and the third guide groove 1603 increase sequentially, and the first guide groove 1601, the second guide groove 1602 and the third guide groove 1603 form the guide groove.

[0062] In the initial state, the cylindrical spring 12 is compressed, and under the elastic force provided by the cylindrical spring 12, the limiting ring 902 can abut against the sliding block 7. At this time, the guide roller 11 and the fan-shaped guide 16 are in a completely misaligned state.

[0063] Furthermore, in the initial state, the abutting shaft 8 can be in contact with the support member 10. At this time, each set of guide rollers 11 is in the same state as the end of the corresponding guide groove. According to the curvature of the curved screen to be detected, the corresponding telescopic shaft 9 can be controlled to move toward the fan-shaped guide member 16 through the extrusion structure. At the same time, the corresponding columnar spring 12 is compressed, and the corresponding guide roller 11 can be inserted into the corresponding guide groove. When the rocker arm 6 swings, the vision monitor 25 can make a circular motion around a predetermined center, and maintain a predetermined distance between itself and the curved screen to be detected during the circular motion to ensure image acquisition accuracy.

[0064] Please see Figures 7-9 The telescopic shaft 9 is provided with a limiting groove 901 along its length direction, and the limiting groove 901 slides in cooperation with the limiting block 701 provided on the sliding block 7.

[0065] The extrusion structure connects multiple sets of the elastic telescopic components, and the extrusion structure can drive one set of guide rollers 11 to be inserted into the corresponding guide groove.

[0066] The extrusion structure includes an electric telescopic rod 15 fixedly mounted on the sliding block 7. A pressure roller 14 is rotatably mounted on the actuating end of the electric telescopic rod 15. A convex shaft 1401 is connected to the rotating shaft of the pressure roller 14. The convex shaft 1401 can roll within a limiting groove 702 set along the length direction of the sliding block 7. The limiting groove 702 has a guiding effect on the convex shaft 1401. This guiding effect allows the pressure roller 14 to move along the length direction of the limiting groove 702 during its movement. When the pressure roller 14 acts on the corresponding pressure-bearing member 13, it can drive the corresponding telescopic shaft 9 to move by the same displacement, so as to ensure that the guide roller 11 can be stably placed in the corresponding guide groove.

[0067] The extrusion structure also includes a pressure receiving member 13 connected to the telescopic shaft 9. The pressure receiving member 13 cooperates with the pressure roller 14 and can drive the telescopic shaft 9 to move relative to the sliding block 7. The side of the pressure receiving member 13 is provided with a first extension 1301 and a second extension 1302. A through groove is formed in the middle of the second extension 1302. The width of the through groove is greater than the width of the first extension 1301. The first extension 1301 on one set of pressure receiving members 13 can be inserted into the through groove in the second extension 1302 on the adjacent set of pressure receiving members 13.

[0068] In the initial state, the pressure roller 14 is in contact with one of the pressure-receiving components 13, allowing one of the guide rollers 11 to be inserted into the corresponding guide groove. In this state, the abutment shaft 8 is in contact with the support component 10, and the ends of each guide roller 11 coincide with the corresponding guide groove. This allows the pressure roller 14 to act sequentially on the pressure-receiving component 13 when the electric telescopic rod 15 moves, causing the corresponding pressure-receiving component 13 to be squeezed and the corresponding guide roller 11 to be inserted into the corresponding guide groove. At this time, when the rocker arm 6 swings, the center of the sliding block 7 and the visual monitor 25 changes during their circular motion to match the curved screen to be inspected, ensuring that the distance between the visual monitor 25 and the curved screen to be inspected remains constant and ensuring image acquisition accuracy.

[0069] For details, please refer to [link / reference] Figure 7 Initially, the lower pressure member 13 is in contact with the pressure roller 14, and the lower guide roller 11 is in a protruding state (inserted into the first guide groove 1601). When it is necessary to change the center of the circular motion of the vision monitor 25, the electric telescopic rod 15 is activated, driving the pressure roller 14 to move along the length direction of the limiting groove 702. During this process, the pressure roller 14 can separate from the lower pressure member 13 and act on the first extension 1301 on the middle pressure member 13, so that the lower telescopic shaft 9 can slowly return to its original position under the action of the column spring 12, until the guide roller 11 and the first guide groove 1601 are in contact. When the rocker arm 6 separates, the pressure member 13 in the middle is pressed, causing the telescopic shaft 9 in the middle to move toward the fan-shaped guide member 16 until the corresponding guide roller 11 is inserted into the second guide groove 1602. At this time, when the rocker arm 6 makes a circular motion, the vision monitor 25 can move along the length direction of the second guide groove 1602. The curved screen to be detected is concentric with the second guide groove 1602, so that the movement trajectory of the vision monitor 25 can be completely parallel to the curved screen to be detected. Thus, when the vision monitor 25 makes a circular motion, it can always maintain a predetermined distance from the curved screen to be detected, thereby ensuring the accuracy of the image acquisition process.

[0070] Please see Figures 2-3 , Figures 10-11 The defoaming visual inspection device for OLED displays with anti-reflective white blocks also includes: a base plate 17, a clamping roller 18, a clamping part 21, and a pneumatic structure.

[0071] The base plate 17 is parallel to the horizontal plate 2 and is fixedly connected to the horizontal plate 2 below it;

[0072] Multiple sets of clamping rollers 18 and clamping parts 21 are provided and slidably mounted on the base plate 17, extending through from below the horizontal plate 2 to above the horizontal plate 2.

[0073] The pneumatic structure connects the clamping rollers 18 and the clamping parts 21. The pneumatic structure can sequentially drive the corresponding two sets of clamping rollers 18 and two sets of clamping parts 21 to move closer to or further away from each other.

[0074] The pneumatic structure includes a first double-headed cylinder 20 fixedly connected to the horizontal plate 2 and a second double-headed cylinder 23 fixedly connected to the base plate 17. The actuating end of the first double-headed cylinder 20 is connected to the clamping roller 18 through the first connecting plate 19, and the second double-headed cylinder 23 is connected to the clamping part 21 through the second connecting plate 22.

[0075] In the initial state, the two sets of clamping rollers 18 and the two sets of clamping parts 21 are all far apart from each other. When the curved screen to be tested is placed on the horizontal plate 2, when the first double-headed cylinder 20 is activated, the two sets of clamping rollers 18 can move closer to each other, thereby positioning the curved screen to be tested along its length direction. After the curved screen is positioned along its length direction, the second double-headed cylinder 23 is activated, causing the two sets of clamping parts 21 to move closer to each other. At this time, the clamping parts 21 can act on the edge of the curved screen, thereby completing the positioning of the curved screen along its width direction.

[0076] Furthermore, in this embodiment, when the curved screen is placed on the horizontal plate 2, its middle part is in a raised state. If the clamping part 21 cannot abut against its end, it will be unable to position the curved screen when the clamping parts 21 move closer to each other. However, through the cooperation of the two sets of clamping rollers 18, the end position of the curved screen can be corrected so that it faces the clamping part 21. This ensures that when the clamping parts 21 move closer to each other, the clamping part 21 can act on the curved screen. When the two sets of clamping parts 21 act on the curved screen and the curved screen moves, the clamping rollers 18 can rotate, thereby reducing the friction between them and the curved screen and preventing damage to the edge of the curved screen.

[0077] Based on the above settings, the curved screen can be accurately positioned during the sequential movement of the clamping roller 18 and the clamping part 21. This ensures that the center of the curved screen is concentric with the center of the guide groove, and that the center of the circular motion of the vision monitor 25 is concentric with the center of the curved screen to be inspected, thus improving the accuracy of image acquisition. On the other hand, it ensures that the curved screen is within the effective acquisition area of ​​the vision monitor 25, ensuring the integrity of image acquisition and improving the detection accuracy to a certain extent.

[0078] As an embodiment of the present invention, a defoaming visual inspection method for an OLED display with anti-reflective white patches is also proposed, which is applied to the aforementioned defoaming visual inspection device for an OLED display with anti-reflective white patches, and includes the following steps:

[0079] Step 1: Place the curved screen to be tested on the horizontal plate 2, start the pneumatic structure, and the pneumatic structure can drive the clamping roller 18 and the clamping part 21 to move in sequence to position the curved screen.

[0080] Step 2: Control the extrusion structure to activate the corresponding elastic telescopic component and allow the corresponding guide roller 11 to be inserted into the corresponding guide groove, which is concentric with the center of the curved screen to be tested.

[0081] Step 3: The rocker arm 6 swings and drives the vision monitor 25 to perform circular motion to acquire images of the curved screen to be inspected;

[0082] Step four: After completing the test, remove the curved screen.

[0083] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
