Technical Field

[0001] This application relates to the field of product testing technology, and in particular to a display module testing 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 modules need to be inspected for edges and aperture areas. Especially for curved screens, it is necessary to check whether the internal and external arc cracks and aperture area cracks meet production requirements.

[0003] Currently, crack detection in display modules is difficult due to the challenges of detecting cracks in the inner and outer arcs and in the hole area.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0039] See Figures 1-4 As shown, this application provides a display module testing device 100, which includes a machine base 110, an inner arc testing mechanism 120, a hole area testing mechanism 130, and an outer arc testing mechanism 140. The inner arc testing mechanism 120, the hole area testing mechanism 130, and the outer arc testing mechanism 140 are sequentially arranged on the machine base 110, such as the inner arc testing mechanism 120, the hole area testing mechanism 130, and the outer arc testing mechanism 140 being arranged sequentially along the flow direction of the product to be inspected. In this embodiment, the product to be inspected is a curved screen. During the inspection of the curved screen, the inner arc crack, outer arc crack, and hole area crack are usually detected. The curved screen includes a screen body, two short sides, and two long sides. The two short sides are located on both sides of the screen body in the length direction, and the two long sides are located on both sides of the screen body in the width direction. The inner arc of the curved screen refers to the concave surface of the long and short sides, and the outer arc of the curved screen refers to the convex surface of the long and short sides. The hole area of ​​the curved screen refers to the area around the holes such as cameras and card slots.

[0040] The inner arc detection mechanism 120 is used to detect inner arc cracks in the product under inspection. The inner arc detection mechanism 120 includes multiple first slide rails 121, which are arranged parallel to each other in their extending direction. The first slide rails 121 allow for the flow of the product under inspection. That is, when the product under inspection flows to the first slide rail 121, the inner arc detection mechanism 120 can perform inner arc crack detection on the product under inspection. Furthermore, the multiple first slide rails 121 allow for the synchronous flow of multiple products under inspection, enabling simultaneous inner arc crack detection on multiple products and improving the efficiency of inner arc crack detection.

[0041] The hole area detection mechanism 130 is used to detect hole area cracks in the product under inspection. The mechanism includes multiple second slide rails 131 arranged parallel to each other in their extending direction, allowing the products to flow between them. That is, when a product reaches a second slide rail 131, the hole area detection mechanism 130 can perform hole area crack detection on it. Furthermore, the multiple second slide rails 131 allow for the simultaneous flow of multiple products under inspection, thereby improving the efficiency of hole area crack detection.

[0042] The outer arc detection mechanism 140 is used to perform outer arc crack detection on the product under inspection, and the outer arc detection mechanism 140 includes a third slide rail 141 for the flow of the product under inspection. That is to say, after the product under inspection has undergone inner arc detection and hole area detection, multiple products under inspection are transferred to the third slide rail 141 for outer arc crack detection. Since only one third slide rail 141 is provided for the flow of multiple products under inspection, an outer arc crack detection element (such as a camera module) can be set at the position corresponding to one third slide rail 141, reducing the number of crack detection elements in the outer arc detection mechanism 140 and reducing the cost of outer arc crack detection for the product under inspection.

[0043] The aforementioned display module testing device 100 firstly, the product to be inspected flows along the first slide rail 121 and undergoes inner arc crack detection via the inner arc detection mechanism 120. Then, after the inner arc crack detection is completed, the product flows to the second slide rail 131 and undergoes hole area crack detection via the hole area detection mechanism 130. Finally, after the hole area crack detection is completed, the product flows to the third slide rail 141 and undergoes outer arc crack detection via the outer arc detection mechanism 140. Thus, through the multi-channel flow of the inner arc detection mechanism 120 and the hole area detection mechanism 130, multiple products to be inspected can undergo inner arc crack and hole area crack detection, improving the crack detection efficiency. Then, the product flows to the single-channel outer arc detection mechanism 140 for outer arc crack detection, reducing the number of crack detection elements (such as camera modules) required within the outer arc detection mechanism 140 and lowering the crack detection cost.

[0044] In one embodiment, see Figure 1 and Figure 2As shown, the inner arc detection mechanism 120 includes multiple first conveying platforms 122, each corresponding to a multiple first slide rail 121. That is, the number and position of the first conveying platforms 122 correspond to the number and position of the first slide rails 121. In this embodiment, there are two first slide rails 121 and two first conveying platforms 122, each positioned on a separate first slide rail 121. The first conveying platforms 122 are slidably mounted on the first slide rails 121 and are used to carry the products to be inspected. For example, the multiple first conveying platforms 122 carry multiple products to be inspected and drive these products to slide on the multiple first slide rails 121, simultaneously performing inner arc crack detection.

[0045] Furthermore, see Figures 1-3 As shown, the hole area detection mechanism 130 includes multiple second conveying platforms 132, each corresponding to a multiple second slide rail 131. That is, the number and position of the second conveying platforms 132 correspond to the second slide rails 131. In this embodiment, there are two second slide rails 131 and two second conveying platforms 132, each positioned on a separate second slide rail 131. The second conveying platforms 132 are slidably mounted on the second slide rails 131 and are used to carry the products to be inspected. For example, the number of second conveying platforms 132 is the same as the number of first conveying platforms 122. After the inner arc of the product to be inspected is detected, the multiple products are transferred to the multiple second slide rails 131 and respectively carried on the multiple second conveying platforms 132. The multiple second conveying platforms 132 drive the multiple products to be inspected to slide on the multiple second slide rails 131 and simultaneously perform hole area crack detection.

[0046] Further, see Figures 1-4 As shown, the outer arc detection mechanism 140 includes a third conveying platform 142, which includes multiple platforms 1421 for carrying the products to be inspected. The third conveying platform 142 is slidably disposed on a third slide rail 141. Exemplarily, the number of platforms 1421 included in the third conveying platform 142 is the same as the number of multiple first conveying platforms 122 and multiple second conveying platforms 132. After the inner arc detection and hole area detection of the products to be inspected are completed, the multiple products to be inspected are transferred to the third slide rail 141, and the third conveying platform 142 disposed on the third slide rail 141 carries multiple products to be inspected simultaneously, and the multiple products to be inspected are simultaneously subjected to outer arc crack detection, realizing the change from multi-channel inner arc detection and hole area detection to single-channel outer arc detection.

[0047] In one embodiment, see Figure 1 , Figure 2 and Figure 5As shown, the inner arc detection mechanism 120 also includes multiple sets of first detection modules 123, which are correspondingly arranged on multiple first slide rails 121. For example, each first slide rail 121 may have a first detection module 123, or each first slide rail 121 may have two sets of first detection modules 123. Each first detection module 123 includes a first short-side detection component 124 and a first long-side detection component 125. The first short-side detection component 124 and the first long-side detection component 125 are spaced apart along the extension direction of the first slide rail 121. The first short-side detection component 124 is used for detecting short-side cracks on the inner arc of the product under inspection, and the first long-side detection component 125 is used for detecting long-side cracks on the inner arc of the product under inspection. For example, the first short-side detection component 124 and the first long-side detection component 125 are spaced apart along the flow direction of the product under inspection. During the sliding process of the product under inspection along the extension direction of the first slide rail 121, the product under inspection undergoes sequential detection of short-side cracks on the inner arc and long-side cracks on the inner arc. It should be noted that the positions of the first short side detection component 124 and the first long side detection component 125 are not restricted. For example, the product to be inspected can be inspected for cracks on the inner arc short side and cracks on the inner arc long side in sequence, or the product to be inspected can be inspected for cracks on the inner arc long side and cracks on the inner arc short side in sequence.

[0048] Specifically, see Figure 1 , Figure 2 and Figure 5 As shown, both the first short-side detection component 124 and the first long-side detection component 125 include a first frame, a first adjustment component 126, and a first camera 127. The first frame is mounted on the machine base 110 by welding, screwing, or other methods to achieve the installation and fixation of the first short-side detection component 124 and the first long-side detection component 125 on the machine base 110. The first camera 127 is movably mounted on the first frame and is used to collect inner arc edge defects of the product to be inspected. The first adjustment component 126 is mounted on the first frame and is used to adjust the movement and rotation of the first camera 127 in three-dimensional space. Thus, by adjusting the first adjustment component 126 in three-dimensional space, the first camera 127 can be moved and rotated relative to the first frame, so that the first camera 127 can focus on the preset inner arc edge position of the product to be inspected for acquisition and shooting. This improves the adjustment freedom of the first short side detection component 124 and the first long side detection component 125. Moreover, for different specifications of products to be inspected or different inner arc edge detection positions of products to be inspected, the angle and position of the first camera 127 can be adjusted to adapt to the long and short side crack detection operations of different specifications of products to be inspected or different inner arc edge detection positions of products to be inspected, thus expanding the application scenarios of the display module detection device 100.

[0049] Further, see Figure 5As shown, the first adjustment assembly 126 includes a first X-axis slide rail 1261, a first Z-axis slide rail 1262, and a first adjustment plate 1263. The first adjustment plate 1263 is slidably mounted on the first frame via the first X-axis slide rail 1261 and the first Z-axis slide rail 1262. The first adjustment plate 1263 is provided with a first arc-shaped groove 1264, and a first camera 127 is disposed in the first arc-shaped groove 1264, and the first camera 127 can slide along the extending direction of the first arc-shaped groove 1264. Thus, the X-axis position of the first camera 127 can be adjusted via the first X-axis slide rail 1261, and the Z-axis position of the first camera 127 can be adjusted via the first Z-axis slide rail 1262. Furthermore, the rotation of the first camera 127 can be adjusted by sliding it within the first arc-shaped groove 1264. In other words, the first adjustment component 126 can perform multi-degree-of-freedom adjustment on the first camera 127 to adapt to the long and short side crack detection operations of different specifications of products to be inspected or different inner arc edge detection positions of products to be inspected, thereby expanding the application scenarios of the display module detection device 100.

[0050] Preferably, the first adjustment component 126 further includes a driving element, which is connected to the first X-axis slide rail 1261, the first Z-axis slide rail 1262 and the first camera 127. The driving element enables the automatic adjustment of the first camera 127, avoiding adjustment errors caused by manual adjustment and improving the reliability of the adjustment of the movement and rotation of the first camera 127.

[0051] In one embodiment, see Figure 1 , Figure 3 and Figure 6 As shown, the hole area detection mechanism 130 also includes multiple sets of second detection modules 133, which are correspondingly arranged on multiple second slide rails 131. For example, each second slide rail 131 may have a second detection module 133, or each second slide rail 131 may have two sets of second detection modules 133. The second detection modules 133 are used for hole area crack detection of the product to be inspected. That is, when the product to be inspected flows from the inner arc detection mechanism 120 to the hole area detection mechanism 130, the product to be inspected flows along the extension direction of the second slide rail 131 and passes through the second detection modules 133 for hole area crack detection.

[0052] Specifically, see Figure 1 , Figure 3 and Figure 6As shown, the second inspection module 133 includes a second frame 134, a second adjustment component 135, and a second camera 136. The second frame 134 is mounted on the machine base 110 by welding, screwing, or other methods to achieve the installation and fixation of the second inspection module 133 on the machine base 110. The second camera 136 is movably mounted on the second frame 134 and is used to collect crack defects in the hole area of ​​the product to be inspected. The second adjustment component 135 is mounted on the second frame 134 and is used to adjust the movement of the second camera 136 in three-dimensional space. Thus, by adjusting the movement of the second camera 136 relative to the second frame 134 in three-dimensional space through the second adjustment component 135, the second camera 136 can focus on the preset hole area position of the product to be inspected for acquisition and imaging, thereby improving the adjustment freedom of the second detection module 133. Furthermore, for different specifications of products to be inspected or different hole area detection positions of products to be inspected, the position of the second camera 136 can be adjusted to adapt to the hole area crack detection of different specifications of products to be inspected or different hole area positions of products to be inspected, thereby expanding the application scenarios of the display module detection device 100.

[0053] Further, see Figure 6 As shown, the second adjustment component 135 includes a second X-axis slide rail 1351 and a second Z-axis slide rail 1352. The second camera 136 is slidably mounted on the second frame 134 via the second X-axis slide rail 1351 and the second Z-axis slide rail 1352. Thus, the X-axis position of the second camera 136 can be adjusted via the second X-axis slide rail 1351, and the Z-axis position of the second camera 136 can be adjusted via the second Z-axis slide rail 1352. In other words, the second adjustment component 135 can perform multi-degree-of-freedom adjustment of the second camera 136 to adapt to the detection of cracks in different specifications of products under inspection or in different hole areas of the products under inspection, thus expanding the application scenarios of the display module inspection device 100.

[0054] Preferably, the second adjustment component 135 further includes a driving element, which is connected to the second X-axis slide rail 1351 and the second Z-axis slide rail 1352. The driving element enables the automatic adjustment of the second camera 136, avoiding adjustment errors caused by manual adjustment and improving the reliability of the movement adjustment of the second camera 136.

[0055] In one embodiment, see Figure 1 , Figure 4 and Figure 7As shown, the outer arc detection mechanism 140 also includes a third detection module 143, which is disposed on the machine base 110 and corresponds to the third slide rail 141. For example, the third slide rail 141 is provided with two sets of third detection modules 143. The third detection module 143 includes a second short side detection component 144 and a second long side detection component 145, which are spaced apart along the extension direction of the third slide rail 141. The second short side detection component 144 is used for detecting short-side cracks on the outer arc of the product to be inspected, and the second long side detection component 145 is used for detecting long-side cracks on the outer arc of the product to be inspected. For example, the second short side detection component 144 and the second long side detection component 145 are spaced apart along the flow direction of the product to be inspected. During the sliding process of the product to be inspected along the extension direction of the third slide rail 141, the product to be inspected undergoes external arc short-side crack detection and external arc long-side crack detection in sequence. It should be noted that the positions of the second short side detection component 144 and the second long side detection component 145 are not restricted. For example, the product to be inspected can be inspected for cracks on the outer arc short side and cracks on the outer arc long side in sequence, or the product to be inspected can be inspected for cracks on the outer arc long side and cracks on the outer arc short side in sequence.

[0056] Specifically, see Figure 1 , Figure 4 and Figure 7 As shown, both the second short-side detection component 144 and the second long-side detection component 145 include a third frame 146, a third adjustment component 147, and a third camera 148. The third frame 146 is mounted on the machine base 110 by welding, screwing, or other methods to achieve the installation and fixation of the second short-side detection component 144 and the second long-side detection component 145 on the machine base 110. The third camera 148 is movably mounted on the third frame 146 and is used to collect the outer arc edge defects of the product to be inspected. The third adjustment component 147 is mounted on the third frame 146 and is used to adjust the movement and rotation of the third camera 148 in three-dimensional space. Thus, by adjusting the movement and rotation of the third camera 148 relative to the third frame 146 in three-dimensional space through the third adjustment component 147, the third camera 148 can focus on the preset outer arc edge position of the product to be inspected for acquisition and shooting, thereby improving the adjustment freedom of the second short side detection component 144 and the second long side detection component 145. Moreover, for different specifications of products to be inspected or different outer arc edge detection positions of products to be inspected, the angle and position of the third camera 148 can be adjusted to adapt to the long and short side crack detection operations of different specifications of products to be inspected or different outer arc edge detection positions of products to be inspected, thereby expanding the application scenarios of the display module inspection device 100.

[0057] Further, see Figure 7As shown, the third adjustment assembly 147 includes a third X-axis slide rail 1471, a third Z-axis slide rail 1472, and a second adjustment plate 1473. The second adjustment plate 1473 is slidably mounted on the third frame 146 via the third X-axis slide rail 1471 and the third Z-axis slide rail 1472. The second adjustment plate 1473 is provided with a second arc-shaped groove 1474, and a third camera 148 is disposed in the second arc-shaped groove 1474, and the third camera 148 can slide along the extension direction of the second arc-shaped groove 1474. Thus, the X-axis position of the third camera 148 can be adjusted via the third X-axis slide rail 1471, and the Z-axis position of the third camera 148 can be adjusted via the third Z-axis slide rail 1472. Furthermore, the rotation of the third camera 148 can be adjusted by sliding it within the second arc-shaped groove 1474. In other words, the third adjustment component 147 can perform multi-degree-of-freedom adjustment of the third camera 148 to adapt to the long and short side crack detection operations of different specifications of products to be inspected or different outer arc edge detection positions of products to be inspected, thereby expanding the application scenarios of the display module detection device 100.

[0058] Preferably, the third adjustment component 147 further includes a driving element, which is connected to the third X-axis slide rail 1471, the third Z-axis slide rail 1472 and the third camera 148. The driving element enables the automatic adjustment of the third camera 148, avoiding adjustment errors caused by manual adjustment and improving the reliability of the adjustment of the movement and rotation of the third camera 148.

[0059] In one embodiment, see Figures 1-4 As shown, the display module testing device 100 also includes a first transfer module 150 and a second transfer module 160, both of which are mounted on the machine base 110. The first transfer module 150 can move between the inner arc testing mechanism 120 and the hole area testing mechanism 130. The first transfer module 150 is used to transfer the product to be tested from the inner arc testing mechanism 120 to the hole area testing mechanism 130, thereby transferring the product to be tested after the inner arc crack detection is completed to the hole area testing mechanism 130 for hole area crack detection. The second transfer module 160 can move between the hole area testing mechanism 130 and the outer arc testing mechanism 140. The second transfer module 160 is used to transfer the product to be tested from the hole area testing mechanism 130 to the outer arc testing mechanism 140, thereby transferring the product to be tested after the hole area crack detection is completed to the outer arc testing mechanism 140 for outer arc crack detection.

[0060] The aforementioned display module testing device 100, through the movement of the first transfer module 150 and the second transfer module 160, enables the product to be inspected to be sequentially transferred between the inner arc testing mechanism 120, the hole area testing mechanism 130 and the outer arc testing mechanism 140, thereby sequentially completing the inner arc crack detection, hole area crack detection and outer arc crack detection of the product to be inspected.

[0061] Additionally, see Figures 1-4 As shown, this application provides a testing device, which includes a display module testing device 100 as described above. The testing device is used to sequentially perform inner arc crack detection, hole area crack detection and outer arc crack detection on the product to be inspected (curved screen).

[0062] The aforementioned testing equipment, through the multi-channel flow of the inner arc testing mechanism 120 and the hole area testing mechanism 130, can perform inner arc crack detection and hole area crack detection on multiple products to be inspected, thereby improving the crack detection efficiency of the products to be inspected. Then, the products to be inspected are transferred to the single-channel outer arc testing mechanism 140 for outer arc crack detection, which can reduce the number of crack detection elements (such as camera modules) in the outer arc testing mechanism 140 and reduce the crack detection cost of the products to be inspected.

[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.
