[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as there is no conflict between them.

[0038] See also Figures 1 to 4 The jig for panel detection in the preferred embodiment of the utility model limits the panel in the X and Y directions through an adjustable limit rod. At the same time, through the preferred design of the position of the vacuum adsorption hole, the panel can be stably adsorbed to the carrier plate to achieve stable limiting of panels of different specifications and sizes.

[0039] Specifically, the jig in the preferred embodiment of the utility model includes a base plate 100, a carrier plate 200 for carrying a panel is arranged on the base plate 100, a clamping assembly 300 is arranged on the carrier plate 200, and the clamping assembly 300 includes two linear guide rails 301 arranged on the carrier plate 200 at intervals along the X direction, and sliders 302 are slidably connected to the two linear guide rails 301; a connecting rod 303 is connected between the two sliders 302, and a limiting structure 304 is slidably sleeved on the connecting rod 303. The limiting structure 304 includes a first rod 3041 and a second rod 3042; wherein the first rod 3041 is slidably sleeved on the connecting rod 303 in the transverse direction; the second rod 3042 is connected to the side of the first rod 3041 away from the center of the carrier plate 200, and the second rod 3042 and the first rod 3041 are orthogonally arranged on the XY plane.

[0040] At the same time, a panel connection module is also arranged on the base plate 100. The panel connection module includes an outer shell and a control board (T-COM board) located in the outer shell, which is used to connect with the FPC of the panel.

[0041] In actual use, the operator first puts the panel on the carrier 200, and then adjusts the position of the limiting structure 304 so that the limiting structure 304 moves along the linear guide rail 301 as a whole, adjusts the position of the limiting structure 304 in the Y direction, and then slides the limiting structure 304 in the direction of the connecting rod 303 to adjust the position of the limiting structure 304 in the X direction. The first rod 3041 and the second rod 3042 are in contact with the corner of the outer periphery of the panel to achieve stable limiting of the corner of the panel.

[0042] It is worth noting that the size of the panel will not be infinitely small, so the utility model can be applied to panels within a certain size range. That is to say, after the panel is limited by the first rod 3041 and the second rod 3042, it will be slightly eccentric with the center of the carrier 200, but the panel will not be completely squeezed to the lower left corner of the entire carrier 200. Therefore, by limiting the corner in this way, the panel within a certain size range can be limited, and the stability of panels of different sizes can be limited.

[0043] Furthermore, considering that when the panel size is large, the limiting of the first rod 3041 and the second rod 3042 may not be able to fully guarantee the stability after limiting. Therefore, the limiting structure 304 in the preferred embodiment of the utility model also includes an auxiliary limiting rod, which is laterally sleeved and slid on the connecting rod 303.

[0044] In actual use, the auxiliary limiting rod can increase the contact area between the limiting structure 304 and the panel. At the same time, due to its laterally adjustable design, the auxiliary limiting rod can be limited to the top of the panel and close to the left side.

[0045] Of course, the auxiliary limiting rod may also be configured to have the same structure as the first rod 3041 and the second rod 3042, that is, Figure 1 The L-shape shown in the figure can stably clamp the two corners of the panel through the two L-shaped limiting structures 304.

[0046] Furthermore, if Figure 1 and Figure 2 As shown in the figure, in order to ensure the stability of the slider 302 after sliding, it is preferred that a lateral guide rail 307 is provided on the base plate 100 corresponding to the two linear guide rails 301, and a connecting block 308 is provided on the side of the slider 302 away from the center of the carrier plate 200, and the connecting block 308 is slidably connected in the lateral guide rail 307; and a knob 309 is also provided on the connecting block 308 for locking the position of the connecting block 308.

[0047] During actual use, the sliding of the slider 302 will synchronously drive the connecting block 308 to move in the lateral guide rail 307, and the operator can lock the position of the connecting block 308 through the knob 309 provided on the connecting block 308, thereby achieving the effect of locking the position of the slider 302.

[0048] Of course, it is understandable that the above method uses manual locking to fix the slider 302. In the actual design process, the two linear guides 301 are also set as linear motors, which can also realize the locking of the position of the slider 302 and the adjustment function of the position of the slider 302.

[0049] Furthermore, if Figure 1 As shown in the figure, in order to achieve the positioning of the first rod 3041 and the second rod 3042 on the connecting rod 303, it is preferred that a plurality of threaded holes are formed on the connecting rod 303 at intervals along the X direction; and a waist-shaped hole is formed on the first rod 3041, and a positioning bolt is arranged in the waist-shaped hole for positioning the position of the first rod 3041.

[0050] In a specific embodiment, the second rod 3042 is arranged at the end of the first rod 3041, the first rod 3041 is slidably connected to the connecting rod 303, and two waist-shaped holes are formed on the first rod 3041, and positioning bolts are arranged in the waist-shaped holes. After the operator slides the first rod 3041 to the specified position, the positioning bolts can be screwed into the corresponding threaded holes to fix the position of the first rod 3041. At the same time, waist-shaped holes and positioning bolts can also be arranged on the auxiliary limiting rod to achieve the fixing operation after the auxiliary limiting rod position is adjusted.

[0051] Furthermore, if Figure 1 and Figure 2 As shown in FIG. 1 , positioning members 306 are respectively provided on both sides of the linear guide rail 301 in the Y direction for positioning the position of the slider 302 .

[0052] In addition, a laser scale 305 is disposed between the two sliders 302 , so that the operator can pre-adjust the position of the first rod 3041 in the X-axis direction according to the laser scale 305 after first understanding the specifications and dimensions of the panel.

[0053] Furthermore, if Figure 1 , Figure 3 and Figure 4As shown in the figure, a vacuum cavity 401 is formed between the base plate 100 and the carrier plate 200; a vacuum adsorption assembly 400 is provided corresponding to the vacuum cavity 401, which includes a switch valve 403 and a vacuum pipe joint 404 provided on the base plate 100, one end of the switch valve 403 is connected to the vacuum cavity 401, and the other end is connected to the outside; one end of the vacuum pipe joint 404 is also connected to the vacuum cavity 401, and the other end is also connected to the outside, and a vacuum hole module 402 is also provided on the carrier plate 200, which is connected to the vacuum cavity 401.

[0054] During the actual setting process, the operator can control the sealing of the entire internal vacuum chamber 401 through the switch valve 403, and the vacuum pipe joint 404 can be used to connect with the external vacuum pump. Figure 1 As shown in FIG. 4 , there are multiple switch valves 403 and vacuum pipe joints 404 .

[0055] More specifically, the vacuum hole module 402 includes two first vacuum units 4021, two second vacuum units 4022, and a third vacuum unit 4023; the first vacuum unit 4021, the second vacuum unit 4022, and the third vacuum unit 4023 are all formed with a plurality of vacuum adsorption holes; Figure 3 As shown in FIG. 2 , the third vacuum unit 4023 is located at the center of the carrier 200 ; the two first vacuum units 4021 are located at both sides of the third vacuum unit 4023 in the X direction; and the two second vacuum units 4022 are located at both sides of the third vacuum unit 4023 in the Y direction.

[0056] It is worth noting that in the prior art, the vacuum adsorption holes are often evenly arranged in a rectangular array on the carrier 200, while the vacuum adsorption holes in the preferred embodiment of the utility model are distributed in several areas near the center of the carrier 200. This adsorption method is based on the above-mentioned limiting structure 304 to limit the side of the panel, and at the same time cooperates with the central adsorption method to achieve stable limitation of the panel.

[0057] Further preferably, the gap between two adjacent vacuum holes in the first vacuum unit 4021, the second vacuum unit 4022 and the third vacuum unit 4023 gradually decreases. In a specific embodiment, the length of the area covered by the vacuum adsorption hole in a first vacuum unit 4021 in the X direction is equal to the length of the second vacuum unit 4022 and the third vacuum unit 4023 in the X direction, and in the Y direction, it is the sum of the lengths of the two second vacuum units 4022 and the third vacuum unit 4023 in the Y direction. Although the density of the vacuum adsorption holes in the first vacuum unit 4021 is the smallest and the gap between two adjacent vacuum adsorption holes is the largest, the area covered by it is the largest; while the gap between two adjacent vacuum adsorption holes in the third vacuum unit 4023 is the smallest, the density is the largest, but the area covered by it is the smallest. This design form can make the vacuum hole module 402 have a larger area that can be adsorbed to adapt to panels of different sizes, and each panel can also be stably adsorbed by the first vacuum unit 4021 with the strongest adsorption force near the center after being limited, ensuring the stability of panels of different sizes after adsorption.

[0058] A multi-stage trapezoidal groove 4024 is formed on the bottom plate 100; and the multi-stage trapezoidal groove 4024 includes a first groove body, a second groove body and a third groove body which are arranged in sequence and arranged vertically; the first groove body, the second groove body and the third groove body respectively correspond to the arrangement positions of the first vacuum unit 4021, the second vacuum unit 4022 and the third vacuum unit 4023. Through this arrangement, vacuum adsorption holes with different adsorption strengths can correspond to vacuum chambers 401 of different sizes.

[0059] On this basis, the utility model also provides a detection device, which includes the fixture in the above preferred embodiment.

[0060] The jig and the testing equipment for panel testing of the utility model have a simple overall structure and are easy to operate. Not only can the panel be limited in the X and Y directions by the limiting rod, but also the panel can be stably adsorbed to the carrier through the optimal design of the position of the vacuum adsorption hole, and the utility model has good practical value and application prospects.

[0061] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
