[0001] This application relates to the field of product testing technology, and in particular to a display module edge detection device and testing equipment. Background Technology

[0002] Currently, smart displays are widely used in businesses, homes, and social activities, with higher requirements for quality and appearance. In daily life, we often see electronic products with interactive screens such as mobile phones, computers, and tablets. During the production process of display screens, the display module needs to be inspected for edge defects, especially for curved screens, where it is necessary to check whether the inner and outer arc cracks meet production requirements.

[0003] Currently, in the crack detection of display modules, since display modules usually have multiple curved edges that need to be detected, in order to comprehensively detect multiple curved edges of the display module, multiple camera modules need to be set up to collect data on different curved edges of the display module, which significantly increases the cost of edge detection of display modules.

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0042] See Figures 1-7As shown, this application provides a display module edge detection device 100, which includes a machine base 110, multiple detection modules 120, a feeding mechanism 130, and a unloading mechanism 140. The display module edge detection device 100 is used to detect edge defects in the product to be inspected, such as detecting the long and short sides of the product. In this embodiment, the product to be inspected is a display screen, such as a flat screen, a curved screen, or other irregularly shaped screen. The product to be inspected includes a screen body, two short sides, and two long sides. The two short sides are located on both sides of the screen body along the length direction of the screen body, and the two long sides are located on both sides of the screen body along the width direction of the screen body. That is to say, the overall shape of the product to be inspected is similar to a cuboid structure.

[0043] The machine 110 has a loading station 111, a unloading station 112, and multiple inspection stations 113. For example, the loading station 111, the multiple inspection stations 113, and the unloading station 112 are arranged sequentially along the flow direction of the products to be inspected. The loading station 111 is used for loading the products to be inspected, the inspection stations 113 are used for edge defect inspection of the products to be inspected, and the unloading station 112 is used for unloading the products to be inspected after inspection.

[0044] Multiple detection modules 120 are spaced apart on the machine tool 110, and each detection module 120 corresponds to a detection position 113. The detection modules 120 are used to detect edge defects in the products to be inspected. For example, there are four detection modules 120, which can simultaneously detect edge defects in four products to be inspected. The number of detection modules 120 is the same as the number of detection positions 113, with one detection module 120 provided at each detection position 113. Multiple detection modules 120 can be used to perform batch inspections on multiple products to be inspected, improving the inspection efficiency.

[0045] The feeding mechanism 130 is installed on the machine base 110 by welding, screwing, or other methods, and includes a feeding platform 131 and a feeding arm 132. The feeding platform 131 is located at the feeding position 111, and the feeding arm 132 can move between the feeding position 111 and any detection position 113. The feeding arm 132 is used to feed the product to be inspected carried by the feeding platform 131 to any detection module 120 (in an idle state), and the detection module 120 performs edge defect detection on the product to be inspected. Since the feeding arm 132 can move to any detection module 120, the product to be inspected can be alternately fed to multiple detection modules 120 without waiting for the detection module 120 to complete its detection time, thus improving the detection efficiency of the product to be inspected.

[0046] The unloading mechanism 140 is installed on the machine base 110 by welding, screwing, or other methods, and includes an unloading platform 141 and an unloading arm 142. The unloading platform 141 is located at the unloading position 112, and the unloading arm 142 can move between the unloading position 112 and any detection position 113. The unloading arm 142 is used to feed the products to be inspected after the detection module 120 has finished detecting them to the unloading platform 141. Since the unloading arm 142 can move to any detection module 120, the products to be inspected after detection can be alternately fed to the unloading platform 141, eliminating the need to wait for the detection module 120 to finish detecting them. The unloading mechanism 140, in conjunction with the loading mechanism 130, improves the detection efficiency of the products to be inspected.

[0047] The aforementioned edge detection device 100 for display modules includes a loading arm 132 that feeds the product to be inspected, carried by a loading platform 131, to any one of the detection modules 120. The detection module 120 performs edge defect detection on the product. After the product is inspected, the unloading arm 142 feeds the inspected product to the unloading platform 141 for unloading. Thus, through the movement of the loading arm 132 and the unloading arm 142 within any one of the detection modules 120, the product to be inspected can be alternately fed to multiple detection modules 120. Each detection module 120 can perform edge defect detection on the product, and multiple detection modules 120 can perform batch inspection of multiple products, improving the inspection efficiency.

[0048] Since the product to be inspected is usually multi-sided, in order to perform multi-sided edge defect detection on the product to be inspected, see [reference] Figures 1-4 As shown, the inspection module 120 includes an image acquisition component 121 and a rotation component 122. The image acquisition component 121 is used to acquire edge defects of the product to be inspected, and the rotation component 122 is used to carry the product to be inspected and rotate it. Thus, after the loading arm 132 moves to the inspection module 120 and places the product to be inspected on the rotation component 122, the rotation component 122 can rotate the product to adjust the edge of the product to be inspected to a position that the image acquisition component 121 can acquire, and perform polygon defect inspection on the product to be inspected through the image acquisition component 121.

[0049] Specifically, see Figure 1 , Figure 2 and Figure 4As shown, the rotating assembly 122 includes a base 1221, a moving module 1222, a rotating platform 1223, and a first microporous adsorption platform 1224. The base 1221 is mounted on the machine base 110 by welding, screwing, or other means. The moving module 1222 is mounted on the base 1221, the rotating platform 1223 is mounted on the moving module 1222, and the first microporous adsorption platform 1224 is mounted on the rotating platform 1223. The first microporous platform is connected to the rotating platform 1223 by transmission. The first microporous adsorption platform 1224 is used to adsorb the product to be inspected. For example, when edge defect detection of a product to be inspected is required, the loading arm 132 moves to the corresponding detection position 113 and places the product to be inspected on the first microporous adsorption platform 1224. The moving module 1222 can adjust the position of the first microporous adsorption platform 1224 in three-dimensional space to feed the product to be inspected carried by the first microporous adsorption platform 1224 to the image acquisition component 121 to obtain the position of edge defects for edge defect detection. The first microporous adsorption platform 1224 stably adsorbs the product to be inspected through negative pressure adsorption, ensuring the stability of the product to be inspected during the detection process. Furthermore, the edge position of the product to be inspected can be adjusted by the rotating component 122 to adjust the edge of the product to be inspected to a position that the image acquisition component 121 can obtain through rotation, and the image acquisition component 121 performs polygon defect detection on the product to be inspected.

[0050] Further, see Figures 1-3 As shown, the image acquisition component 121 includes an image terminal 1211 and an adjustment module 1212. The image terminal 1211 is disposed on the adjustment module 1212 and is used to acquire edge defects of the product under inspection. The adjustment module 1212 is disposed on the machine base 110 and is used to adjust the pose of the image terminal 1211 in three-dimensional space. When the specifications of the product under inspection change, or when the edge to be detected of the product under inspection is not within the field of view of the image terminal 1211, the pose of the image terminal 1211 is adjusted by the adjustment module 1212 to adapt to the edge defect detection of products with different specifications, or to ensure that the edge to be detected of the product under inspection is within the field of view of the image terminal 1211, thereby expanding the application scenarios of the image acquisition component 121 or ensuring the accuracy of the image terminal 1211 in acquiring edge defects of the product under inspection.

[0051] In this embodiment, the adjustment module 1212 includes multiple adjustment axes. The adjustment module 1212 allows for movement and rotation of the image terminal 1211 within the XYZ space, thereby increasing the adjustment range of the image terminal 1211. Furthermore, the image terminal 1211 can be an industrial camera (CCD). The image terminal 1211 acquires edge defects of the product under inspection in image form and visualizes them on the user interface.

[0052] In one embodiment, see Figure 1 , Figure 2 and Figure 5 As shown, the detection module 120 also includes a precision alignment module 123, which is used for precise alignment of the product to be inspected. For example, when the feeding arm 132 feeds the product to be inspected to the detection module 120, the precision alignment module 123 can precisely align the product to be inspected so that the product to be inspected is in a preset detection position for edge defect detection, thereby improving the detection accuracy and reliability of the product to be inspected.

[0053] In this embodiment, the precision alignment module 123 includes an adjustment component 1231 and at least one detection camera 1232. The detection camera 1232 is connected to the adjustment component 1231. The adjustment component 1231 can compensate the X-axis and Z-axis of the detection camera 1232 so that the center of the field of view of the detection camera 1232 is exactly at the edge of the product to be inspected. The position and pose of the product to be inspected are visualized on the user interface through the detection camera 1232, which facilitates the position and pose adjustment of the product to be inspected.

[0054] In one embodiment, see Figure 1 and Figure 2 As shown, multiple detection modules 120 are along the first direction ( Figure 1 The feeding mechanism 130 and the unloading mechanism 140 are spaced apart along the second direction (as shown in direction A). Figure 1 The detection modules 120 are spaced apart on opposite sides of each other in direction B (as shown). The first direction and the second direction are coplanar, and the angle between them is 0 < α < 180°. By placing the loading mechanism 130 and the unloading mechanism 140 on opposite sides of the detection modules 120, the spatial layout of the display module edge detection device 100 can be reduced, making the structure of the display module edge detection device 100 more compact. In this embodiment, for example, there are four detection modules 120, spaced apart along the first direction, which is perpendicular to the second direction (α = 90°). Of course, in other feasible embodiments, the angle α between the first and second directions can be 30°, 60°, 120°, 150°, or other values. This application does not limit the specific angle between the first and second directions.

[0055] In this embodiment, see Figure 4As shown, the moving module 1222 includes a slide rail 1225 and a moving member 1226 slidably disposed on the slide rail 1225. The slide rail 1225 extends along a second direction, and a rotating platform 1223 is disposed on the moving member 1226. For example, the loading arm 132 moves to the corresponding detection position 113 and places the product to be inspected on the first microporous adsorption platform 1224. The moving member 1226 slides along the slide rail 1225 toward the image terminal 1211, feeding the product to be inspected carried by the first microporous adsorption platform 1224 to below the image terminal 1211. The image terminal 1211 then performs multi-sided edge defect detection on the product to be inspected. After the product to be inspected is inspected, the moving member 1226 moves along the slide rail 1225 toward the unloading mechanism 140, and the unloading arm 142 feeds the inspected product to the unloading platform 141 for unloading.

[0056] In one embodiment, see Figure 1 , Figure 2 and Figure 6 As shown, both the loading platform 131 and the unloading platform 141 include a UVW slide 150 and multiple second microporous adsorption platforms 151. The UVW slide 150 is mounted on the machine base 110 by welding, screwing, or other methods. Multiple second microporous adsorption platforms 151 are mounted on the UVW slide 150 and are driven by it. The second microporous adsorption platforms 151 are used to adsorb the products to be inspected. Thus, the negative pressure adsorption platforms of the multiple second microporous adsorption platforms 151 enable batch loading or unloading of multiple products to be inspected, improving the loading and unloading efficiency and consequently the inspection efficiency. Furthermore, since the multiple second microporous adsorption platforms 151 are mounted on the UVW slide 150, the UVW slide 150 can compensate for the X, Y, and R axes of the products to be inspected, improving the inspection accuracy.

[0057] For example, in this embodiment, both the loading platform 131 and the unloading platform 141 include two second microporous adsorption platforms 151, which can simultaneously complete the loading and unloading operations of two products to be inspected. Of course, in other feasible embodiments, the number of second microporous adsorption platforms 151 can be other, and this application does not limit the specific number of second microporous adsorption platforms 151.

[0058] Further, see Figure 1 , Figure 2 and Figure 7As shown, there are multiple loading arms 132 and multiple unloading arms 142. Multiple loading arms 132 can correspondingly feed the products to be inspected, adsorbed by multiple second microporous adsorption platforms 151, to the detection module 120, thereby completing the loading operation of multiple products to be inspected and improving the loading efficiency. Multiple unloading arms 142 can correspondingly feed the products to be inspected after being inspected by the detection module 120 to multiple second microporous adsorption platforms 151, thereby completing the unloading operation of multiple products to be inspected and improving the unloading efficiency.

[0059] It should be noted that, in this embodiment, the number of feeding arms 132 is the same as the number of second microporous adsorption platforms 151. Multiple feeding arms 132 can simultaneously feed the products to be inspected adsorbed by multiple second microporous adsorption platforms 151 to the corresponding detection module 120 for feeding operations. Similarly, the number of unloading arms 142 is the same as the number of second microporous adsorption platforms 151. Multiple unloading arms 142 can simultaneously feed the products to be inspected after being detected by the corresponding detection module 120 to the multiple second microporous adsorption platforms 151 for unloading operations.

[0060] Additionally, see Figure 8 As shown, this application also provides a testing device 200, which includes a display module edge detection device 100 as described above. The testing device 200 can perform edge defect detection on the product to be inspected, such as long and short side detection on the product to be inspected.

[0061] In one embodiment, see Figures 1-8As shown, the testing equipment 200 includes a loading component 210, a scanning component 220, a first flipping component 230, a pre-alignment component 240, a first cleaning component 250, a loading mechanism 130, a testing module 120, a discharging mechanism 140, a second flipping component 260, a second cleaning component 270, and a discharging component 280, which are sequentially arranged on the machine base 110. That is to say, the loading component 210, the scanning component 220, the first flipping component 230, the pre-alignment component 240, the first cleaning component 250, the loading mechanism 130, the testing module 120, the discharging mechanism 140, the second flipping component 260, the second cleaning component 270, and the discharging component 280 are arranged sequentially along the flow direction of the products to be inspected. Among them, the loading component 210 can load the products to be inspected onto the testing equipment 200, such as, but not limited to, a robotic arm. The barcode scanner 220 can scan the product information of the product to be inspected. The first flipper 230 can flip the product to be inspected, such as flipping the product to the front or back for edge defect detection. The pre-alignment device 240 can perform preliminary alignment of the product to be inspected to ensure the detection position accuracy, such as aligning a camera. The first cleaning device 250 can perform surface cleaning operations on the product to be inspected, such as using an air knife. The second flipper 260 can flip the product to be inspected to the front or back for easy unloading. The second cleaning device 270 can perform surface cleaning operations on the product after inspection, such as using an air knife. The unloading device 280 can unload the product after inspection, such as using a robotic arm.

[0062] The aforementioned testing equipment 200 firstly, the loading unit 210 loads the product to be inspected onto the machine base 110; secondly, the product to be inspected is transferred to the barcode scanner 220 for barcode scanning to record the product information; next, the product to be inspected is transferred to the first flipping unit 230, which flips the product to the front or back for edge defect detection; then, the product to be inspected is transferred to the pre-alignment unit 240 for preliminary alignment to ensure the accuracy of the detection position; then, the product to be inspected is transferred to the first cleaning unit 250 for surface cleaning to avoid deviations in the detection results due to surface contamination; finally, the product to be inspected is transferred to the display module edge detection device 100, and the loading arm 1... 32. The product to be inspected, carried by the loading platform 131, is fed to any detection module 120. The detection module 120 performs edge defect detection on the product to be inspected. After the product to be inspected is inspected, the unloading arm 142 feeds the inspected product to the unloading platform 141 for unloading. Continuing, the product to be inspected is transferred to the second flipping component 260, which flips the product to be inspected to a front or back position for easy unloading. Continuing further, the product to be inspected is transferred to the second cleaning component 270, which performs surface cleaning on the inspected product. Finally, the product to be inspected is transferred to the unloading component 280, which performs unloading on the inspected product.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
