[0030] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application. However, the present application can be implemented in many different ways other than those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0031] In the description of the present application, it should be understood that if these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0032] 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.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] 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.

[0035] 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.

[0036] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0037] See Figure 1 and Figure 2As shown, this application provides a testing mechanism 100, which includes a fixing base 110, a driving component 120 and a testing module 130. The testing mechanism 100 is used to perform testing operations on the display panel for performance, appearance and other aspects.

[0038] The drive assembly 120 is mounted on the fixed base 110 by welding, screwing, or other means. The drive assembly 120 includes a drive source 121 and a lead screw 122. The lead screw 122 is throttle-connected to the output end of the drive source 121. When the drive source 121 outputs power to the lead screw 122, the drive source 121 can drive the lead screw 122 to rotate around its axis. Exemplarily, in this embodiment, the drive source 121 can be a drive motor, drive cylinder, or other component capable of outputting power. This application does not limit the specific component type of the drive source 121.

[0039] The detection module 130 is engaged with the lead screw 122, and the detection module 130 can move along the extension direction of the lead screw 122. Thus, during the rotation of the lead screw 122, the detection module 130 can move along the extension direction of the lead screw 122, and the detection module 130 can move to different detection points on the display panel to perform performance, appearance, and other detection operations.

[0040] The aforementioned testing mechanism 100 only requires one testing module 130. The testing module 130 moves along the lead screw 122 to each testing point, and the testing module 130 can perform testing operations on each testing point of the display panel in sequence, reducing the testing cost of the display panel. Furthermore, the movement of the testing module 130 driven by the rotation of the lead screw 122 can improve the movement accuracy of the testing module 130, thereby ensuring the alignment accuracy between the testing module 130 and each testing point.

[0041] In one embodiment, see Figures 1-3 As shown, the detection module 130 includes a detection probe 131 and a sliding seat 132. The detection probe 131 is disposed on the sliding seat 132. If the sliding seat 132 is a plate structure, it facilitates the installation and fixation of the detection probe 131. The sliding seat 132 is engaged with the lead screw 122. Thus, the rotation of the lead screw 122 drives the sliding seat 132 to move along the extension direction of the lead screw 122, thereby driving the detection probe 131 to move between each detection point, and sequentially performing detection operations on each detection point of the display panel.

[0042] Preferably, the detection probe 131 is detachably connected to the sliding seat 132 by means of screwing, snap-fitting, etc., so that by replacing the detection probe 131 of different specifications and models, it can adapt to different detection operations and expand the application scenarios of the detection mechanism 100.

[0043] In one embodiment, see Figures 1-3As shown, the detection mechanism 100 also includes a guide rail 140. The guide rail 140 is disposed on the sliding seat 132, and the extension direction of the guide rail 140 is consistent with that of the lead screw 122. For example, if both the guide rail 140 and the lead screw 122 extend along... Figure 1 Extending in the X direction, the sliding seat 132 is slidably mounted on the guide rail 140. In this way, the guide rail 140 can limit and guide the sliding direction of the sliding seat 132, so that when the sliding seat 132 is engaged with the lead screw 122 at different positions, the sliding seat 132 can drive the detection probe 131 to move along a preset path, thereby improving the alignment accuracy between the detection probe 131 and each detection point.

[0044] Further, see Figures 1-3 As shown, there are two guide rails 140. The two guide rails 140 are respectively positioned on opposite sides of the lead screw 122, and the sliding seat 132 is synchronously slidably positioned on the two guide rails 140. Thus, since the sliding seat 132 meshes with the lead screw 122, the lead screw 122 provides a certain meshing resistance to the sliding operation of the sliding seat 132. By positioning the two sides of the sliding seat 132 on the two guide rails 140 respectively, the undesirable phenomenon of the sliding seat 132 wobbling due to the meshing resistance during sliding is avoided, thereby improving the stability of the detection probe 131 during movement.

[0045] In one embodiment, see Figures 1-3 As shown, the detection module 130 also includes a mounting base 133 and a fine-tuning component 134. The mounting base 133 is movably disposed on the sliding base 132, the detection probe 131 is disposed on the mounting base 133, and the fine-tuning component 134 is kinetically connected to the mounting base 133. The fine-tuning component 134 is used to fine-tune the position of the mounting base 133 in three-dimensional space, further improving the alignment accuracy between the detection probe 131 and each detection point. For example, see [reference needed]. Figure 1 and Figure 3 As shown, if the fine-tuning component 134 is a Z-axis adjustment component, the fine-tuning component 134 can adjust the detection probe in the Z direction. Figure 1 The Z-axis position is adjusted as shown. Of course, in other feasible embodiments, such as when the detection point of the display module is offset, or when detecting display modules of different specifications, the position of the mounting base 133 in three-dimensional space can be finely adjusted by the fine-tuning component 134, thereby finely adjusting the position of the detection probe 131 to adjust the detection probe 131 to a position adapted to the detection point.

[0046] Specifically, see Figure 3As shown, the fine-tuning component 134 includes a fixed part 1341 and a telescopic part 1342. The telescopic part 1342 is telescopically disposed on the fixed part 1341 and is convexly connected to the fixed part 1341. The telescopic part 1342 is connected to the mounting base 133. When it is necessary to fine-tune the position of the detection probe 131, the telescopic part 1342 is subjected to twisting, stretching, or other methods, causing the protruding part of the telescopic part 1342 relative to the fixed part 1341 to lengthen or shorten. Since the telescopic part 1342 is connected to the mounting base 133, the extension and retraction of the telescopic part 1342 relative to the fixed part 1341 can drive the mounting base 133 to move, thereby fine-tuning the position of the detection probe 131 and improving the alignment accuracy between the detection probe 131 and each detection point.

[0047] In one embodiment, see Figures 2-4 As shown, the detection probe 131 is detachably mounted on the mounting base 133, such as by screwing or snapping. This allows for the replacement of different specifications of the detection probe 131 to meet various detection requirements.

[0048] For example, such as Figure 3 As shown, the detection probe 131 is a short-range probe. When short-range detection is required, the short-range detection probe 131 is connected to the mounting base 133 to perform short-range detection on each detection point of the display panel. Similarly, as... Figure 4 As shown, the detection probe 131 is a long-distance probe. When there is a need for long-distance detection, the long-distance detection probe 131 is connected to the mounting base 133, and long-distance detection can be performed on each detection point of the display panel.

[0049] Since the detection probe 131 needs to operate under power, it is connected to a wire assembly. During the movement of the detection probe 131, the wire assembly is prone to damage or breakage due to dragging (especially over long distances), rendering the detection probe 131 unable to perform detection operations. Therefore, in one embodiment, see... Figure 1 and Figure 4As shown, the detection mechanism 100 also includes a base 150 and a telescopic bracket 160. The base 150 is fixed to the fixed base 110. One end of the telescopic bracket 160 is connected to the base 150, and the other end of the telescopic bracket 160 is connected to the sliding base 132. The telescopic direction of the telescopic bracket 160 is consistent with the extension direction of the lead screw 122. The telescopic bracket 160 is used to fix the wire assembly of the detection probe 131. For example, the wire assembly of the detection probe 131 can be fixed to the telescopic bracket 160 by winding, binding, or other means. When the detection probe 131 moves along the extension direction of the lead screw 122, since the telescopic bracket 160 is connected to the sliding seat 132, the telescopic bracket 160 moves in a telescopic motion and drives the wire assembly of the detection probe 131 to move along a preset path. On the one hand, this avoids damage or breakage of the wire assembly of the detection probe 131 due to excessive dragging during the movement, thus protecting the wire assembly of the detection probe 131. On the other hand, fixing the wire assembly of the detection probe 131 prevents it from moving freely and causing interference with other structures.

[0050] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the drive assembly 120 also includes a transmission module 123. The transmission module 123 is disposed between the drive source 121 and the lead screw 122. The transmission module 123 is used to transmit the power of the drive source 121 to the lead screw 122, so that the lead screw 122 can rotate around its axis. Since the detection module 130 is engaged with the lead screw 122, during the rotation of the lead screw 122, the detection module 130 can move along the extension direction of the lead screw 122, and the detection module 130 can move to different detection points on the display panel to perform performance, appearance and other detection operations.

[0051] In one embodiment, see [reference] Figures 1-3 As shown, the transmission module 123 includes a first gear set 1231, a second gear set 1232, and a transmission shaft 1233. The first gear set 1231 and the second gear set 1232 are respectively connected to opposite ends of the transmission shaft 1233, and the first gear set 1231 is connected to the output end of the drive source 121, while the second gear set 1232 is connected to the lead screw 122. For example, when the drive source 121 outputs power, it outputs power to the first gear set 1231. Since the first gear set 1231 and the second gear set 1232 are respectively connected to opposite ends of the transmission shaft 1233, and the second gear set 1232 is connected to the lead screw 122, the drive source 121 can transmit power to the lead screw 122 through the first gear set 1231, the transmission shaft 1233, and the second gear set 1232. The rotation of the lead screw 122 drives the detection probe 131 to move between various detection points.

[0052] Specifically, see Figures 1-3As shown, the first gear set 1231 includes a first transmission gear 1234 and a second transmission gear 1235, which mesh with each other. The first transmission gear 1234 is located at the output end of the drive source 121, and the second transmission gear 1235 is located at one end of the transmission shaft 1233. The second gear set 1232 includes a third transmission gear 1236 and a fourth transmission gear 1237, which mesh with each other. The third transmission gear 1236 is located at the other end of the transmission shaft 1233, and the fourth transmission gear 1237 is located at the end of the lead screw 122. Thus, when the detection probe 131 needs to be moved to the detection point, the drive source 121 outputs power to the first transmission gear 1234. Since the first transmission gear 1234 meshes with the second transmission gear 1235, the first transmission gear 1234 drives the second transmission gear 1235 to rotate. The second transmission gear 1235 drives the transmission shaft 1233 to rotate. The rotation of the transmission shaft 1233 drives the third transmission gear 1236 to rotate. Since the third transmission gear 1236 meshes with the fourth transmission gear 1237, the third transmission gear 1236 drives the fourth transmission gear 1237 to rotate. This transmits the power of the drive source 121 to the lead screw 122, which in turn drives the detection probe 131 to move between the detection points.

[0053] In another embodiment, see [reference] Figure 1 , Figure 3 and Figure 4 As shown, the transmission module 123 includes a gearbox 124 and multiple meshing transmission gears (not shown), all of which are housed within the gearbox 124. One of the transmission gears is connected to the output end of the drive source 121, and another of the transmission gears is connected to the lead screw 122. Thus, when the detection probe 131 needs to be moved to the detection point, the drive source 121 outputs power to one of the transmission gears. Due to the meshing of the multiple transmission gears, the power from the drive source 121 is transmitted to the transmission gear connected to the lead screw 122 through the meshing motion of the multiple transmission gears, thereby transmitting the power from the drive source 121 to the lead screw 122. The movement of the lead screw 122 then drives the detection probe 131 to move between the detection points.

[0054] It should be noted that the transmission gears installed in the gearbox 124 can be two, three, four, or other numbers. This application does not limit the specific number of transmission gears installed in the gearbox 124. For example, when there are two transmission gears, one transmission gear is connected to the output end of the drive source 121, and the other transmission gear is connected to the lead screw 122; or when there are three transmission gears, one of the three transmission gears is connected to the output end of the drive source 121, and the other of the three transmission gears is connected to the lead screw 122. For other numbers of transmission gears, they can be set in the same way as described above, and will not be elaborated further here.

[0055] Additionally, see Figure 1 , Figure 2 and Figure 5 As shown, this application also provides a testing device 200, which includes a cavity 210 and at least one testing mechanism 100 as described above. The testing mechanism 100 is disposed within the cavity 210. By disposing the testing mechanism 100 within the cavity 210, the testing mechanism 100 can perform performance, appearance, and other testing operations on the display panel inside the cavity 210. In this embodiment, the display panel is placed flat inside the cavity, and the testing mechanism 100 is disposed on the side of the cavity 210. The testing mechanism 100 can perform testing operations on the side testing points of the display panel and avoid interference with the display panel during movement. Of course, in other feasible embodiments, the testing mechanism 100 can also be disposed in the middle of the cavity 210 to accommodate testing operations at different testing points of the display panel. That is to say, this application does not limit the specific placement of the testing mechanism 100 and can be adaptively set according to the position of the testing points.

[0056] The aforementioned detection device 200 only requires one detection module 130. The detection module 130 moves along the lead screw 122 to each detection point, and the detection module 130 can perform detection operations on each detection point of the display panel in sequence, reducing the detection cost of the display panel. Furthermore, the movement of the detection module 130 driven by the rotation of the lead screw 122 can improve the movement accuracy of the detection module 130, thereby ensuring the alignment accuracy between the detection module 130 and each detection point.

[0057] 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.

[0058] 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.
