Description

Technical Field

[0001] The present application relates to the technical field of aging testing, and in particular to a tray for display screen aging testing. Background Art

[0002] As a simple, convenient, and natural human-computer interaction device, displays have been widely used in various fields, including mobile phones, in-car navigation systems, industrial control, medical treatment, and self-service terminals, greatly enriching the user experience. Displays are typically formed by laminating a glass cover plate to an LCD panel. To ensure the quality of the display, these laminated displays must undergo high-temperature aging testing. Displays that yellow during the high-temperature aging test are screened out and discarded.

[0003] Currently, high-temperature aging testing for displays involves placing the display on a tray, then placing the tray with the display in a high-temperature aging device. To improve aging efficiency, multiple trays carrying the display are often stacked before being placed in the high-temperature aging device for testing.

[0004] However, the stacked pallets will cause the internal space of the lower pallet to be closed, and the interior of the lower pallet cannot effectively transfer heat to the outside world. On the one hand, this affects the aging and heating efficiency of the display screen located inside the pallet. On the other hand, it will cause the display screen inside the pallet to be insufficiently heated and unable to reach the preset temperature after the aging is completed, affecting the aging test results. After aging in the above environment, the display screen is prone to yellow spots, bubbles and other adverse phenomena, which will affect the user's visual experience when put into use. If used in a vehicle, it will seriously affect the user's driving safety. Utility Model Content

[0005] Based on this, it is necessary to provide a tray for display screen aging testing to address the problem that after the trays carrying display screens are stacked, the interior of the lower tray cannot effectively transfer heat to the outside world.

[0006] A tray for display screen aging testing includes a base plate and side walls arranged around the base plate, the side walls and the base plate forming a accommodating cavity with one end open, the accommodating cavity being used to place the display screen, and an exhaust port is provided on the side walls that penetrates the side walls along the thickness direction of the side walls, and the exhaust port is communicated with the accommodating cavity.

[0007] In one embodiment, the exhaust port is connected to the top end of the side wall.

[0008] In one embodiment, the side wall includes a first side panel, a second side panel, a third side panel and a fourth side panel arranged around the bottom panel, and the exhaust port is provided on the first side panel, the second side panel, the third side panel and the fourth side panel.

[0009] In one embodiment, an escape groove communicating with the top end of the side wall is provided on the outer side of the side wall.

[0010] In one embodiment, the first side panel and the second side panel are symmetrically arranged with respect to the bottom panel, and the avoidance groove provided on the first side panel and the avoidance groove provided on the second side panel are staggered.

[0011] In one embodiment, the display screen aging test tray further includes a locking assembly, which includes a first locking assembly and a second locking assembly, wherein the first locking assembly has a plug-in protrusion, and the second locking assembly has a plug-in groove adapted to the plug-in protrusion, and the first locking assembly is arranged on one of the top end of the side wall and the bottom end of the side wall, and the second locking assembly is arranged on the other of the two.

[0012] In one embodiment, there are multiple locking components, and the multiple locking components are arranged at intervals.

[0013] In one embodiment, a first clearance groove is further formed on the inner side of the side surrounding wall. The height direction of the first clearance groove is parallel to the height direction of the side surrounding wall, and one end of the first clearance groove along its own height direction is connected to the top end of the side surrounding wall, and the other end is connected to the abutment portion of the side surrounding wall that abuts against the bottom plate.

[0014] The bottom plate is provided with a second paving groove which is in communication with the first paving groove.

[0015] In one embodiment, a third paving groove connected to the top end of the side wall is further provided on the inner side of the side wall, and the third paving groove is parallel to the first paving groove.

[0016] In one embodiment, the bottom plate is further provided with a plurality of fourth relief grooves arranged at intervals.

[0017] The display burn-in test tray features exhaust vents on its side walls that connect to the cavities. When multiple trays are stacked, each tray transfers heat from the high-temperature burn-in equipment to the cavities through its own exhaust vents, allowing the display screens within the cavities to heat up promptly. This effectively improves the display's heating efficiency, preventing insufficient heating and preventing the screen from reaching the preset temperature. This enhances the burn-in test results, avoids undesirable phenomena such as yellow spots and bubbles that often occur after burn-in, and ensures the quality of the display production.

[0033] See Figure 1 and Figure 2 As shown, Figure 1 FIG. 1 shows a schematic structural diagram of a display screen aging test tray 10 in an embodiment of the present application. Figure 2 for Figure 1An enlarged schematic diagram of the structure at A in the middle. An embodiment of the present application provides a tray 10 for display screen aging testing, which is used to carry a display screen and then place it together in a high-temperature aging device to perform an aging test on the display screen. The above-mentioned tray 10 for display screen aging testing includes a base plate 100 and a side wall 200 arranged around the base plate 100, the side wall 200 and the base plate 100 form a receiving cavity 300 with one end open, the receiving cavity 300 is used to place the display screen, and an exhaust port 210 is provided on the side wall 200 and passes through the side wall 200 along the thickness direction of the side wall 200, and the exhaust port 210 is communicated with the receiving cavity 300.

[0034] The display burn-in test tray 10 features exhaust vents 210 on its side walls 200, connected to the accommodating cavity 300. When multiple trays are stacked, each tray can transfer the heat from the high-temperature burn-in equipment to the accommodating cavity 300 through its own exhaust vents 210, thereby allowing the display screen inside the accommodating cavity 300 to heat up promptly. This effectively improves the display screen's heating efficiency, preventing the screen from failing to reach the preset temperature due to insufficient heating. This enhances the burn-in test results, avoids undesirable phenomena such as yellow spots and bubbles that often occur after display burn-in, and ensures the production quality of the display screen.

[0035] To enhance heat transfer between the tray and the outside, a preferred embodiment provides that the exhaust port 210 is connected to the top of the side wall 200. In practice, the exhaust port 210 can be in any shape, such as a circle or rectangle with one end open. This configuration increases the heat transfer area, thereby enhancing the heat transfer effect.

[0036] To facilitate the design of the side wall 200, a preferred embodiment includes a first side panel 220, a second side panel 230, a third side panel 240, and a fourth side panel 250 disposed around the bottom panel 100. Exhaust ports 210 are provided on each of the first side panel 220, the second side panel 230, the third side panel 240, and the fourth side panel 250. Specifically, the first side panel 220, the second side panel 230, the third side panel 240, and the fourth side panel 250 are connected in a hollow rectangular structure, and each of the side panels is provided with a plurality of exhaust ports 210 spaced apart from each other.

[0037] When multiple pallets are stacked, in order to facilitate the removal of the pallets, a relief groove 260 connected to the top of the side wall 200 is provided on the outer side of the side wall 200. In a specific configuration, a plurality of relief grooves 260 are provided on the first side panel 220, the second side panel 230, the third side panel 240, and the fourth side panel 250. Through the above configuration, a worker's fingers or a robot finger can conveniently remove the pallet located above the relief groove 260 through the relief groove 260. In a specific configuration, the relief groove 260 opens at the top of the side wall 200 and extends along the height direction of the side wall 200. Part of the relief groove 260 is connected to the exhaust port 210. To prevent workers from being scratched when removing pallets, the corners of the relief groove 260 are provided with arc chamfers.

[0038] In the specific setting, the first side panel 220 and the second side panel 230 are symmetrically arranged with respect to the bottom panel 100, and the avoidance groove 260 provided on the first side panel 220 and the avoidance groove 260 provided on the second side panel 230 are staggered. Through the above setting, when stacking, the first side panel 220 on the upper layer can be stacked with the second side panel 230 on the lower layer, which is convenient for subsequent disassembly. It should be noted that the third side panel 240 and the fourth side panel 250 are symmetrically arranged with respect to the length direction of the bottom panel 100, and the avoidance groove 260 on the third side panel 240 and the avoidance groove 260 on the fourth side panel 250 can be arranged opposite each other or staggered. In order to enhance the heat transfer of the tray, the exhaust port 210 on the third side panel 240 and the exhaust port 210 on the fourth side panel 250 are arranged one by one opposite each other.

[0039] Combine Figure 3 As shown, Figure 3 for Figure 1 Another perspective structural diagram of the display burn-in test tray 10 is shown in FIG. In some embodiments, to increase stability when stacking trays, a preferred embodiment includes a locking assembly 400 comprising a first locking member and a second locking member. The first locking member has a plugging protrusion 410, and the second locking member has a plugging groove 420 that mates with the plugging protrusion 410. The first locking member is disposed on one of the top or bottom ends of the side wall 200, while the second locking member is disposed on the other end. Specifically, the plugging groove 420 is preferably located on the inner side of the side wall 200, with one end of the plugging groove 420 communicating with the top end of the side wall 200. The depth of the plugging groove 420 is less than the height of the side wall 200. With this arrangement, when multiple trays are stacked, the first or second locking member at the bottom of the upper tray mates with the corresponding second or first locking member at the top end of the lower tray.

[0040] To enhance the secureness of the pallet stacking, multiple locking assemblies 400 are provided, and the multiple locking assemblies 400 are spaced apart. Specifically, multiple locking assemblies 400 are provided on each of the first side panel 220, the second side panel 230, the third side panel 240, and the fourth side panel 250. When the insertion grooves 420 in the locking assemblies 400 are formed at the top of the side wall 200, the insertion grooves 420 are spaced apart from the exhaust port 210.

[0041] To facilitate access to the display screen within the accommodating cavity 300, a preferred embodiment further comprises a first clearance groove 270 formed on the inner side of the side wall 200. The height direction of the first clearance groove 270 is parallel to the height direction of the side wall 200, and one end of the first clearance groove 270 along its own height direction is connected to the top of the side wall 200, and the other end is connected to the abutment portion of the side wall 200 that abuts the bottom plate 100. A second clearance groove 110 is formed on the bottom plate 100 and is connected to the first clearance groove 270. In a specific configuration, there are multiple first clearance grooves 270 and multiple second clearance grooves 110, and the multiple first clearance grooves 270 correspond one-to-one with the multiple second clearance grooves 110, and the projection of the first clearance groove 270 on the bottom plate 100 is located within the corresponding second clearance groove 110. With this arrangement, when a worker's finger or a robot's finger slides down through the first clearance groove 270 to the second clearance groove 110, the finger will be lower than the upper surface of the bottom plate 100, i.e., the surface supporting the display screen, making it easier to pick up the display screen located on the upper surface of the bottom plate 100. It should be noted that, in this application, the third side panel 240 and the fourth side panel 250 of the side wall 200 are preferably provided with the first clearance groove 270.

[0042] To facilitate the removal of display screens of varying heights, a third clearance slot 280 is specifically defined on the inner side of the side wall 200 and communicates with the top of the side wall 200. The third clearance slot 280 is parallel to the first clearance slot 270. Specifically, the depth of the third clearance slot 280 is less than the height of the side wall 200, so that the bottom wall of the third clearance slot 280 is at a first height relative to the bottom plate 100. When the display screen is higher than the first height, the third clearance slot 280 allows for convenient removal of the display screen, thus ensuring that taller displays can be removed through the third clearance slot 280. It should be noted that, in the present application, multiple, spaced-apart third clearance slots 280 are defined on each of the first side panel 220, the second side panel 230, the third side panel 240, and the fourth side panel 250, some of which communicate with the exhaust port 210. It should be emphasized that when the insertion groove 420 in the locking component 400 is opened at the top of the side wall 200, the insertion groove 420 is spaced apart from the third clearance groove 280 and the second clearance groove 110, and the depth of the insertion groove 420 is less than the depth of the third clearance groove 280.

[0043] To accommodate displays of varying sizes, the base plate 100 must be no smaller than the largest display. Therefore, some smaller displays cannot fit into the second clearance grooves 110. To facilitate access to these smaller displays, a preferred embodiment includes a plurality of spaced fourth clearance grooves 120 on the base plate 100. In practice, the fourth clearance grooves 120 are preferably waist-shaped, making it easier to access displays of varying widths.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0045] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
