[0034] Reference Figure 1 The multi-screen includes a plurality of display modules 101 at a certain angle to each other and a protective cover 102 for protecting the display modules 101. The protective cover 102 has a plurality of protection areas 103 that are integrally connected and bent to each other. At least one display module 101 is attached to each protection area 103. After the display modules 101 are attached to the protective cover 102, the display planes of different display modules 101 face different directions. The protective cover 102 can be set to a C-shape, L-shape, or the like.

[0035] Reference Figure 2 and Figure 3 In an embodiment of the utility model, a multi-screen pressing device (hereinafter referred to as pressing device) is provided, which is used to press a plurality of display modules 101 onto different protection zones 103 of a protective cover plate 102, and the adjacent protection zones 103 are bent relative to each other. The pressing device includes a pressing plate 100, a pressing jig 200 and a supporting jig 300. The pressing jig 200 is located below the pressing plate 100. The pressing jig 200 includes a first pressing portion 210 and a second pressing portion 220 that is bent vertically relative to the first pressing portion 210. The first pressing portion 210 is arranged horizontally, the ground of the first pressing portion 210 forms a first pressing surface 211, and the bottom surface of the second pressing portion 220 forms a second pressing surface 221. The support jig 300 is located below the pressing jig 200. The support jig 300 is used to support the protective cover 102 and the display module 101. The support jig 300 includes a horizontally arranged first support portion 310 and a second support portion 320 vertically bent relative to the first support portion 310. The top surface of the first support portion 310 forms a first support surface 311, and the top surface of the second support portion 320 forms a second support surface 321. The first support surface 311 is parallel to the first pressing surface 211, and the second support surface 321 is parallel to the second pressing surface 221.

[0036] The display module 101 and the protective cover plate 102 are located between the support jig 300 and the pressing jig 200, and the support jig 300 is used to support the display module 101 and the protective cover plate 102; the pressing plate 100 is driven to move downward and press the pressing jig 200 downward, and the pressing jig 200 and the pressing plate 100 move downward synchronously and approach the support jig 300 until the pressing jig 200 and the support jig 300 jointly press the display module 101 and the protective cover plate 102; When the pressing jig 200 and the supporting jig 300 press the display module 101 and the protective cover plate 102, the supporting jig 300 supports the display module 101 and the protective cover plate 102, and at the same time, one of the protection zones 103 and one of the display modules 101 are pressed between the first pressing surface 211 and the second pressing surface 221, and the other protection zone 103 and the other display module 101 are pressed between the second pressing surface 221 and the second supporting surface 321.

[0037] It can be understood that the protective cover 102 has formed a shape in which the protection zones 103 are bent relative to each other before being pressed, and the bending angle and bending direction between the first pressing surface 211 and the second pressing surface 221, the bending angle and bending direction between the first supporting surface 311 and the second supporting surface 321, and the bending angle and bending direction between the two protection zones 103 are all the same; therefore, when the protection zone 103 and the display module 101 are pressed between the first supporting surface 311 and the first pressing surface 211 or between the second supporting surface 321 and the second pressing surface 221, the original bending angle between adjacent protection zones 103 can be maintained, and relative bending between adjacent protection zones 103 can be avoided, thereby enabling the display module 101 to be stably pressed with the protection zone 103, thereby improving the pressing quality of the protective cover 102 and the display module 101 in the multi-screen.

[0038] The pressing device also includes an elastic pad 400, which is flexible and is arranged on the top of the supporting fixture 300. The elastic pad 400 includes a first elastic portion 410 and a second elastic portion 420 that is bent vertically relative to the first elastic portion 410. The top surface of the first elastic portion 410 is parallel to the first pressing surface 211, and the top surface of the second elastic portion 420 is parallel to the second pressing surface 221. When the protective cover 102 and the display module 101 are pressed, they are located between the pressing fixture 200 and the elastic pad 400. The first elastic portion 410 can be perpendicular to the pressing surface 211. The first elastic portion 410 can be stretched and retracted in the direction of the first supporting surface 311, the second elastic portion 420 can be stretched and retracted in a direction perpendicular to the second supporting surface 321, the elastic pad 400 can absorb the displacement of the display module 101 and the protection panel during the pressing process, the elastic pad 400 flexibly contacts the elastic pad 400 or the protection cover 102, the display module 101 and the protection zone 103 located between the first elastic portion 410 and the first pressing portion 210, and the display module 101 and the protection zone 103 located between the second elastic portion 420 and the second pressing portion 220 will not be damaged due to hard pressing.

[0039] When the protective cover plate 102 and the display module 101 are pressed, the display module 101 is located above the protective cover plate 102. The display module 101 has a certain gravity. Under the pressing action of the pressing jig 200, the display module 101 and the protective cover plate 102 can be more tightly combined. The elastic pad 400 on the top of the support jig 300 is in contact with the protective cover plate 102 and absorbs the displacement of the protective cover plate 102 and the display module 101 during the pressing process, providing a buffer for the protective cover plate 102 and the display module 101.

[0040] The elastic pad 400 is configured as a retractable soft pad made of foam, silicone, rubber or other materials, or the elastic pad 400 includes a plurality of springs arranged side by side. In addition, the elastic pad 400 can also be made of a heat-insulating material, so that the elastic pad 400 has a heat-insulating property to reduce the influence of high temperature on the display module 101 and the protective cover plate 102 during the pressing process.

[0041] The pressing device also includes a heating module 500, which is accommodated inside the supporting jig 300. The heating module 500 can release heat after being powered on. The heat released by the heating module 500 is transferred to the first supporting surface 311 and the second supporting surface 321. The first supporting surface 311 transfers heat to the protection area 103 located between the first supporting surface 311 and the first pressing surface 211, so that the hot melt adhesive between the protection area 103 and the display module 101 is heated and melted and flows, thereby achieving a close fit between the protection area 103 and the display module 101; similarly, the second supporting surface 321 transfers heat to the protection area 103 located between the second supporting surface 321 and the second pressing surface 221, so that the hot melt adhesive between the protection area 103 and the display module 101 is heated and melted and flows, thereby achieving a close fit between the protection area 103 and the display module 101.

[0042] It is understandable that since the elastic pad 400 is located on the top of the supporting jig 300, the first supporting surface 311 and the second supporting surface 321 have high temperatures due to the heating effect of the heating module 500, and the elastic pad 400 can prevent the first supporting surface 311 and the second supporting surface 321 from damaging the protective cover 102 or the display module 101 due to the high temperature; in addition, since the display module 101 is located on the side of the protective cover 102 away from the heating module 500, the effect of the high temperature on the display module 101 can be further reduced to avoid damage to the multi-screen display.

[0043] The support fixture 300 is provided with a first heating zone and a second heating zone inside. The first heating zone is arranged in the first support part 310, and the second heating zone is arranged in the second support part 320. There are multiple heating modules 500, and some of the heating modules 500 are located in the first heating zone and used to heat the first support surface 311, and some of the heating modules 500 are located in the second heating zone and used to heat the second support surface 321. That is, the first support surface 311 and the second support surface 321 are heated by different heating modules 500, which is convenient for independently controlling the heating temperature of the first support surface 311 and the second support surface 321. When there is a difference in the pressing temperature between different protection areas 103 and the display module 101, the first support surface 311 and the second support surface 321 can be heated to different pressing temperatures by adjusting the heating modules 500 in the first heating zone or the second heating zone, and the pressing device has high practical performance.

[0044] In addition, each heating module 500 includes a plurality of parallel and independently heated heating rods 510. Different heating rods 510 can switch the on and off state of the heating rods 510 through an external operation module. For example, the operation module is set as an operation button. When the operation button is turned on, the heating rod 510 works and heats after being powered on. When the operation button is closed, the heating rod 510 does not work. In this way, the heating power, heating temperature, etc. of the heating module 500 can be adjusted by adjusting the number of working heating rods 510 in the heating module 500. In addition, when selecting some heating rods 510 in a certain heating module 500 to work, multiple uniformly distributed heating rods 510 can be selected to work, so that the heating module 500 heats the first support surface 311 or the second support surface 321 more uniformly. In addition, multiple heating modules 500 can be set in the first heating zone and the second heating zone, and each heating module 500 is provided with one or more heating rods 510. According to needs, one or more heating modules 500 in the first heating zone or the second heating zone can be selected not to work, or one or more heating rods 510 in a certain heating module 500 can be selected not to work.

[0045] Furthermore, multiple heating modules 500 are detachably connected to the support fixture 300, which is convenient for disassembly and assembly and subsequent maintenance of the heating modules 500, or by increasing or decreasing the number of heating modules 500, changing the pressing temperature of the first support surface 311 and the second support surface 321. The heating module 500 includes a shell and a heating rod 510 disposed in the shell. The detachable connection method of the heating module 500 is not limited to threaded connection, clamping, etc.

[0046] In one embodiment, the pressing jig 200 also includes a third pressing portion 230, and the third pressing portion 230 and the second pressing portion 220 are arranged on two opposite sides of the first pressing portion 210, and the third pressing portion 230 is bent vertically relative to the first pressing portion 210, and the bottom surface of the third pressing portion 230 forms a third pressing surface 231; the supporting jig 300 also includes a third supporting portion 330, and the second supporting portion 320 and the third supporting portion 330 are arranged on two opposite sides of the first supporting portion 310, and the third supporting portion 330 is bent vertically relative to the first supporting portion 310, and the top surface of the third supporting portion 330 forms a third supporting surface 331, and the third supporting surface 331 is parallel to the third pressing surface 231.

[0047] During the lamination process of the display module 101 and the protective cover plate 102, the display module 101 and the protection zone 103 are provided between the first supporting surface 311 and the first pressing surface 211, between the second supporting surface 321 and the second pressing surface 221, and between the third supporting surface 331 and the third pressing surface 231, so that multiple areas of the protective cover plate 102 can be pressed with different display modules 101 at the same time, thereby improving the pressing efficiency of the pressing device.

[0048] In addition, the support fixture 300 also includes a third heating zone, the second heating zone and the third heating zone are respectively located on two opposite sides of the first heating zone, the third heating zone is arranged in the third support portion 330, and part of the heating module 500 is located in the third heating zone and is used to heat the third support surface 331.

[0049] Similarly, the elastic pad 400 may also be provided with a third elastic portion 430, and the third elastic portion 430 and the second elastic portion 420 are respectively provided on two opposite sides of the first elastic portion 410, and the third elastic portion 430 is vertically bent relative to the first elastic portion 410, and the top surface of the third elastic portion 430 is parallel to the third pressing surface 231. During the pressing process of the display module 101 and the protective cover plate 102, the display module 101 and the protection zone 103 located between the first supporting surface 311 and the first pressing surface 211, between the second supporting surface 321 and the second pressing surface 221, and between the third supporting surface 331 and the third pressing surface 231 can be elastically buffered by the elastic pad 400, thereby reducing the damage to the display module 101 and the protective cover plate 102 during the pressing process.

[0050] In one embodiment, the second pressing portion 220 and the third pressing portion 230 have the same bending direction relative to the first pressing portion 210, and the second supporting portion 320 and the third supporting portion 330 have the same bending direction relative to the first supporting portion 310, that is, the second pressing portion 220 and the third pressing portion 230 are both bent upward or downward relative to the first pressing portion 210, and the second supporting portion 320 and the third supporting portion 330 are both bent upward or downward relative to the first supporting portion 310. On the one hand, it adapts to the bending shape of the protective panel, and on the other hand, the display module 101 and the protective cover plate 102 located between the first pressing portion 210 and the first supporting portion 310, between the second pressing portion 220 and the second supporting portion 320, and between the third pressing portion 230 and the third supporting portion 330 are subjected to the same pressing force trend, and the pressing effect between different display modules 101 and the protection area 103 is more uniform.

[0051] Furthermore, the second pressing portion 220 and the third pressing portion 230 are bent toward the supporting jig 300 relative to the first pressing portion 210, and the second supporting portion 320 and the third supporting portion 330 are bent away from the pressing jig 200 relative to the first supporting portion 310, that is, the second pressing portion 220 and the third pressing portion 230 are both bent downward relative to the first pressing portion 210, and the second supporting portion 320 and the third supporting portion 330 are both bent downward relative to the first supporting portion 310, so as to avoid interference with the supporting jig 300 during the downward movement of the pressing jig 200 and before it cooperates with the supporting jig 300 to press the display module 101 and the protective cover plate 102, resulting in obstruction of the movement of the pressing jig 200 and affecting the normal pressing of the display module 101 and the protective cover plate 102.

[0052] The pressing plate 100 is used to press the top of the first pressing part 210 in the pressing fixture 200. Since the first pressing part 210 and the first supporting part 310 are both arranged horizontally, when the pressing plate 100 drives the first pressing part 210 to descend, the second pressing part 220 and the third pressing part 230 move synchronously and are jointly subjected to force. When the first pressing part 210 descends to a preset height and cooperates with the first supporting part 310 to press the protective cover plate 102 and the display module 101, the second pressing part 220 moves synchronously. The pressing plate 100 moves to a preset height and cooperates with the second supporting portion 320, and the third pressing portion 230 moves synchronously to a preset height and cooperates with the third supporting portion 330, that is, the pressing plate 100 can press the first pressing portion 210 to make the pressing fixture 200 and the corresponding area of ​​the supporting fixture 300 cooperate synchronously, and stably press the protective cover plate 102 and the display module 101. The pressing plate 100 does not need to be set to the same structural form as the pressing fixture 200, and the processing of the pressing plate 100 is more convenient.

[0053] In one embodiment, the interior of the laminating jig 200 is provided with an adsorption chamber 240, and a plurality of spaced adsorption holes 250 are provided at the bottom, the adsorption holes 250 are communicated with the adsorption chamber 240, the adsorption chamber 240 is connected to an external negative pressure gas source, and negative pressure can be generated inside the adsorption chamber 240 and in the adsorption holes 250, so as to adsorb the display module 101 on the first laminating surface 211 or the second laminating surface 221. The display module 101 can be pre-adsorbed on the bottom surface of the laminating jig 200, and synchronously descend with the laminating jig 200. When the laminating jig 200 descends to a preset height and the display module 101 contacts the protective panel, the negative pressure in the laminating jig 200 is removed, the display module 101 contacts the protective panel, and is supported by the protective panel. The display module 101 and the protective panel are pressed together by the laminating jig 200 and the supporting jig 300.

[0054] The pressing jig 200 also includes an elastic component 600, which is arranged at the bottom of the supporting jig 300 and supports the supporting jig 300. The elastic component 600 includes a plurality of elastic members 610 arranged at intervals in the horizontal direction, and the elastic members 610 can be retracted in the vertical direction. During the pressing process of the display module 101 and the protective cover 102, there is a situation where the attachment plane of the display module 101 is not parallel to the attachment plane of the protective cover 102, which will cause the display module 101 and the different areas of the protection zone 103 to be The contact force is inconsistent, there are gaps in some areas, and some areas are too tight. To address this situation, an elastic component 600 is provided at the bottom of the pressing fixture 200. The elastic parts 610 at different positions in the elastic component 600 can adaptively expand and contract and level according to the contact force between the display module 101 and different areas of the protection zone 103, thereby compensating for the inconsistent pressing force between different areas of the display module 101 and the protection zone 103, and making the pressing force between different areas of the display module 101 and the protection zone 103 tend to be uniform.

[0055] It is understandable that the elastic member 610 can be configured as a component capable of elastic expansion and contraction such as a spring or a spring sheet, and the elastic member 610 is arranged in an array along multiple directions in a horizontal plane.

[0056] The pressing device also includes a pressing chamber 700, in which the pressing plate 100, the pressing jig 200 and the supporting jig 300 are all arranged. The pressing chamber 700 provides a clean process environment for the pressing of the display module 101 and the protective cover plate 102, reduces the influence of the external environment on the pressing process, and improves the display effect of the multi-screen after pressing.
