Description

Technical Field

[0001] This application relates to the field of screen detection equipment technology, and in particular to a screen adsorption platform. Background Technology

[0002] During the production process, flexible screens need to undergo transportation and testing. These processes require fixing the flexible screen in place to prevent it from moving around randomly and to avoid affecting the testing accuracy due to positional shifts.

[0003] In traditional methods, a flat aluminum plate platform is often used to fix the flexible screen. Specifically, the flexible screen is placed on a flat aluminum plate platform, and small holes (with a diameter between 0.3mm and 0.5mm) on the platform are used in conjunction with a vacuum adsorption air path to firmly adsorb the flexible screen, thereby preventing the flexible screen from moving during the testing or processing.

[0004] However, in actual adsorption fixation, while ensuring adsorption effectiveness, the relatively large pore size of the adsorption pores means that when vacuum suction is applied to the flexible screen, especially in the central region, the concentrated suction force from the pores causes the screen, lacking sufficient peripheral support, to deform under the influence of the concentrated suction, resulting in noticeable adsorption depressions around the pores. Conversely, reducing the adsorption force at this point leads to insufficient adsorption around the flexible screen, causing it to warp. Both of these situations potentially damage the screen's microstructure and performance, thus affecting the accuracy of subsequent detection.

[0005] Based on this, this application proposes a screen adsorption platform to solve the technical problems existing in the above-mentioned traditional methods. Utility Model Content

[0006] To address the aforementioned technical issues, this application provides a screen adsorption platform that can reduce the occurrence of screen adsorption depressions and minimize the impact on detection accuracy.

[0007] This application provides a screen adsorption platform, comprising:

[0008] Adsorption body, partitioned adsorption blocks, first adsorption gas path and second adsorption gas path;

[0009] The upper surface of the adsorption body is provided with a through first adsorption hole, one side of the adsorption body is connected to the first adsorption gas path, and the first adsorption gas path is connected to the first adsorption hole.

[0010] The other side of the adsorption body is connected to the partitioned adsorption block. The upper surface of the partitioned adsorption block is provided with a second adsorption hole. The diameter of the second adsorption hole is larger than that of the first adsorption hole. The second adsorption gas path is provided on the partitioned adsorption block and is connected to the second adsorption hole. When the first adsorption gas path and the second adsorption gas path are respectively pumped, the screen is fixed on the adsorption body and the partitioned adsorption block.

[0011] Optionally, the adsorption body includes a base plate, an adsorption plate, and an adsorption frame. The adsorption frame is disposed on the base plate, the adsorption plate is connected above the adsorption frame, and the adsorption plate is provided with a plurality of first adsorption holes.

[0012] The first adsorption gas path passes through the side of the adsorption frame and extends inward to connect with a plurality of the first adsorption holes.

[0013] Optionally, the partitioned adsorption block and the adsorption frame are connected in a detachable manner.

[0014] Optionally, the adsorption frame is connected to the base plate by screws.

[0015] Optionally, the upper surface of the adsorption frame is lower than the upper surface of the adsorption plate.

[0016] Optionally, the base plate is provided with a hollow area.

[0017] Optionally, the partition adsorption block is provided with a positioning structure, which is used to position the screen to be tested, and the positioning structure is controlled to move on the partition adsorption block.

[0018] Optionally, the positioning structure is a positioning block, with a groove provided on the partitioned adsorption block. One end of the positioning block is movably connected in the groove, and the other end extends upward to the upper surface of the partitioned adsorption block. The positioning block is controllable and can move in the groove.

[0019] Optionally, the pore size of the second adsorption pore is in the range of 0.2 mm to 0.5 mm.

[0020] Optionally, the pore size of the first adsorption pore is in the range of 0.04mm-0.06mm.

[0021] As can be seen from the above technical solutions, this application has the following effects:

[0022] This application connects the adsorption body and the partitioned adsorption block to each other. A first adsorption hole is provided on the adsorption body, and a second adsorption hole is provided on the partitioned adsorption block. The diameter of the first adsorption hole is smaller than that of the second adsorption hole. The first adsorption hole on the adsorption body is connected to a first adsorption gas path, and the second adsorption hole on the partitioned adsorption block is connected to a second adsorption gas path. The screen is placed simultaneously on both the adsorption body and the partitioned adsorption block. By controlling the suction of the first and second adsorption gas paths, the screen is fixed to both the adsorption body and the partitioned adsorption block. The adsorption body adsorbs most of the flexible screen, while the partitioned adsorption block adsorbs one edge of the flexible screen. This area-based adsorption fixation, combined with the smaller diameter of the first adsorption hole compared to the second adsorption hole, prevents adsorption depression in the center of the flexible screen and increases the adsorption force on one edge of the flexible screen, reducing the likelihood of warping and improving the overall adsorption effect.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] This application provides a screen adsorption platform to reduce screen adsorption and depression, thereby minimizing the impact on detection accuracy. The specific implementation process of this application is described below.

[0037] Please see Figures 1 to 6 The screen adsorption platform provided in this application includes:

[0038] The adsorption body 01, the partitioned adsorption block 02, the first adsorption gas path 03, and the second adsorption gas path 04 are configured. The upper surface of the adsorption body 01 is provided with a through first adsorption hole 05. One side of the adsorption body 01 is connected to the first adsorption gas path 03, and the first adsorption gas path 03 is connected to the first adsorption hole 05. The other side of the adsorption body 01 is connected to the partitioned adsorption block 02. The upper surface of the partitioned adsorption block 02 is provided with a second adsorption hole 06. The diameter of the second adsorption hole 06 is larger than the diameter of the first adsorption hole 05. The second adsorption gas path 04 is disposed on the partitioned adsorption block 02, and the second adsorption gas path 04 is connected to the second adsorption hole 06. When the first adsorption gas path 03 and the second adsorption gas path 04 are respectively pumping air, the screen is fixed on the adsorption body 01 and the partitioned adsorption block 02.

[0039] In the actual adsorption process, the flexible screen 13 (the screen to be tested) is placed on both the adsorption body 01 and the partitioned adsorption block 02, with one edge of the flexible screen 13 aligned with the edge of the partitioned adsorption block 02. When the first adsorption gas path 03 is activated, a downward vacuum suction force is generated in the first adsorption hole 05, thereby tightly adsorbing and fixing the flexible screen 13 to the upper surface of the adsorption body 01. When the second adsorption gas path 04 is activated, a downward vacuum suction force is also generated in the second adsorption hole 06, thereby tightly adsorbing and fixing one edge of the flexible screen 13 to the upper surface of the partitioned adsorption block 02.

[0040] The first adsorption gas path 03 and the second adsorption gas path 04 are connected to the positive pressure gas path and the negative pressure gas path, respectively. During the adsorption process, the negative pressure gas path is activated, generating a downward adsorption force in the first adsorption hole 05 and the second adsorption hole 06, thereby adsorbing and fixing the flexible screen 13. When the positive pressure gas path is activated, an upward thrust is generated in the first adsorption hole 05 and the second adsorption hole 06, thereby releasing the flexible screen 13.

[0041] The partitioned adsorption block 02 is connected to one side of the adsorption body 01, and the upper surface of the adsorption body 01 is flush with the upper surface of the partitioned adsorption block 02, ensuring that the flexible screen 13 is adsorbed flat.

[0042] The flexible screen 13 has sufficient support around its perimeter. Therefore, the diameter of the second adsorption hole 06 on the partition adsorption block 02 is larger than that of the first adsorption hole 05, which has a strong adsorption force to ensure that the flexible screen 13 is firmly fixed. In addition, the larger hole diameter makes it less likely to become clogged.

[0043] In this embodiment, by setting adsorption bodies 01 and partitioned adsorption blocks 02 with different pore sizes, and controlling them separately through different adsorption gas paths, it is possible to avoid using a large pore size in the middle area of ​​the flexible screen 13, thereby reducing the occurrence of adsorption depressions. Furthermore, using partitioned adsorption blocks 02 to adsorb and fix one edge of the flexible screen 13 provides both strong adsorption force and reduces the possibility of the flexible screen 13 edge lifting. In addition, reducing the area of ​​small pores reduces the possibility of adsorption pore blockage.

[0044] In an optional embodiment, the adsorption body 01 includes a base plate 07, an adsorption plate 08, and an adsorption frame 09. The adsorption frame 09 is disposed on the base plate 07, and the adsorption plate 08 is connected above the adsorption frame 09. The adsorption plate 08 is provided with a plurality of first adsorption holes 05. The first adsorption gas passage 03 passes through the side of the adsorption frame 09 and extends inward to connect with the plurality of first adsorption holes 05.

[0045] In this embodiment, the base plate 07 is used to connect with other equipment (transport line or testing equipment), the adsorption plate 08 is a plate that contacts the flexible screen 13, and a plurality of first adsorption holes 05 are provided on the plate. The adsorption plate 08 is fixed above the adsorption frame 09, and the adsorption plate 08 and the adsorption frame 09 are sealed together. One end of the adsorption frame 09 is connected to the partition adsorption block 02, and the corresponding end is fixed with the first adsorption gas path 03. The first adsorption gas path 03 passes through one end face of the adsorption frame 09 (the side of the adsorption frame 09) and extends into the adsorption frame 09. After extending, it communicates with the first adsorption holes 05 on the adsorption plate 08.

[0046] In this optional embodiment, the partitioned adsorption block 02 and the adsorption frame 09 are connected in a detachable manner. The detachable method can be a snap-fit ​​connection or a bolt or screw connection. The specific detachable method selected is subject to actual feasibility and is not limited here.

[0047] In this optional embodiment, the adsorption frame 09 and the base plate 07 are connected by screws. A connection hole is provided on the adsorption frame; the screw is screwed into the connection hole and then screwed downwards into the base plate 07, thereby connecting the adsorption frame 09 and the base plate 07. This screw connection allows for easy disassembly of the base plate 07 and the adsorption frame 09 as needed, facilitating maintenance and replacement.

[0048] In this optional embodiment, the upper surface of the adsorption frame 09 is lower than the upper surface of the adsorption plate 08. In this embodiment, setting the upper surface of the adsorption plate 08 higher than the upper surface of the adsorption frame 09 can prevent collisions between the flexible screen 13 and the adsorption frame 09 when the flexible screen 13 is placed, thereby reducing damage to the flexible screen 13.

[0049] Please refer to the following for details. Figure 2 In one optional embodiment, the base plate 07 has a hollowed-out area. In this embodiment, the hollowed-out area on the base plate 07 can reduce the weight of the base plate 07 and also reduce the production cost of the base plate 07.

[0050] Please refer to the following for details. Figure 4 and Figure 5 In an optional embodiment, a positioning structure is provided on the partitioned adsorption block 02. This positioning structure is used to position the screen to be tested and is controlled to move on the partitioned adsorption block 02. In this embodiment, the positioning structure on the partitioned adsorption block 02 positions the screen to be tested, ensuring that the center of the screen is aligned with the center line of the adsorption body 01, thus facilitating the control and adsorption of the adsorption gas path. For screens of different sizes, arbitrarily placing them on the adsorption body 01 would be extremely inconvenient for controlling the number of adsorption holes in the adsorption gas path, causing problems in the adsorption process. Therefore, a positioning structure is provided. The position of the positioning structure is changed according to the size of the screen to be tested, ensuring that the center line of the screen to be tested is always aligned with the center line of the adsorption body 01, improving the convenience of adsorption control and the adsorption effect.

[0051] In this optional embodiment, the positioning structure is a positioning block 10. A groove 11 is provided on the partitioned adsorption block 02. One end of the positioning block 10 is movably connected in the groove 11, and the other end extends upward to the upper surface of the partitioned adsorption block 02. The positioning block 10 can be controlled to move in the groove 11. The groove 11 is provided on the side of the partitioned adsorption block 02 facing away from the adsorption body 01. One end of the positioning block 10 is movably connected in the groove 11. By applying an external force to the positioning block 10, the positioning block 10 can be moved along the groove 11. The groove 11 is parallel to the upper surface of the partitioned positioning block 10. The other end of the positioning block 10 is higher than the upper surface of the partitioned positioning block 10 and extends towards the adsorption body 01.

[0052] In addition, in order to quickly adjust the position of the positioning block 10, a scale 12 is set on the partition adsorption block 02. The scale 12 is set according to the size of different flexible screens 13, so that the position of the positioning block 10 can be quickly adjusted according to the size of the screen to be tested. Each time the screen to be tested is placed, one side of the screen to be tested is placed close to the positioning block 10 to achieve alignment between the screen to be tested and the center line of the adsorption body 01.

[0053] In one optional embodiment, the pore size of the second adsorption pore 06 is in the range of 0.2 mm to 0.5 mm.

[0054] In one optional embodiment, the pore size of the first adsorption pore 05 is in the range of 0.04mm-0.06mm, such as using a ceramic platform adsorption structure as the adsorption body 01.

[0055] Additionally, please refer to the following for details. Figure 3 The control process for different adsorption gas paths during the adsorption and fixation of flexible screens 13 of different sizes is as follows:

[0056] For ease of description, the five first adsorption gas paths 03 and the nine second adsorption gas paths 04 are described as follows: Figure 3 The markings indicate that when adsorbing 1-3 inch flexible screens 13, adsorption gas paths ① and A are opened simultaneously for adsorption; when adsorbing 5-7 inch flexible screens 13, adsorption gas paths ①, ②, A, and B are opened simultaneously for adsorption; when adsorbing 7-10 inch flexible screens 13, all adsorption gas paths (①, ②, ③, A, B, and C) are opened simultaneously for adsorption.

[0057] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
