[0023] This utility model embodiment provides a pressure-holding device for assembling a display module and a back cover, see reference. Figures 1 to 6The pressure-holding device includes a pressure-holding platform 1 and a pressure-holding upper platform 2 connected to a frame platform. It should be noted that the frame platform is not shown in the accompanying drawings. The frame platform is, for example, the base of an assembly equipment for assembling a display module and a back cover. The pressure-holding platform 1 is connected to the frame platform, and the pressure-holding upper platform 2 is connected to the frame platform via a support structure. The pressure-holding upper platform 2 is vertically and flexibly positioned above the pressure-holding platform 1. The lower surface of the pressure-holding upper platform 2 has a contoured surface adapted to the shape of the back surface of the back cover. When using this pressure-holding device to hold pressure on the pre-pressed display module and back cover, the pre-pressed display module and back cover are loaded onto the pressure-holding platform 1, wherein the other side of the display module facing away from the bonding surface is connected to the pressure-holding platform 1, and the pressure-holding upper platform 2 presses down on the back surface of the back cover facing away from the bonding surface from top to bottom.

[0024] The pressure-holding platform 1 includes a support base 11, a vacuum adsorption assembly 12, and multiple support plate assemblies 13 located outside the vacuum adsorption assembly 12. These support plate assemblies 13 combine to form a support plane for supporting the product to be pressure-held (the pre-pressed and bonded display module and back cover). The vacuum adsorption assembly 12 is vertically and vertically connected to the support base 11, and each support plate assembly 13 is vertically and horizontally movable and connected to the support base 11. That is, the height of the vacuum adsorption assembly 12 on the support base 11 is adjustable, and the height and size of the support plane formed by the multiple support plate assemblies 13 for supporting the product to be pressure-held are also adjustable. This allows the height of the support plane to be adjusted according to the thickness of the product to be pressure-held, and the size of the support plane to be adjusted according to the length and width of the product to be pressure-held. This makes it applicable to various specifications of display module products, improving the versatility of the pressure-holding device and reducing production costs.

[0025] In this embodiment, a linear drive module 3 is connected to the machine frame platform, and the linear drive module 3 is connected between the pressure holding station 100 and the loading station 200. The support base 11 is movably connected to the linear drive module 3. A lifting drive mechanism 4 is connected to the machine frame platform within the pressure holding station 100, and the pressure holding upper platform 2 is vertically connected to the lifting drive mechanism 4 and located above the linear drive module 3. As a preferred embodiment, the support base 11 has a flat plate structure.

[0026] As provided in the above embodiment, the pressure-holding device works as follows: First, the pressure-holding platform 1 moves on the linear drive module 3 to the loading station 200. The product to be pressure-held is loaded onto the pressure-holding platform 1 by manual or automatic loading equipment, and the vacuum adsorption component 12 adsorbs and fixes the product to be pressure-held. Then, the pressure-holding platform 1 moves on the linear drive module 3 to the pressure-holding station 100, and the pressure-holding upper platform 2 is controlled to descend and press against the back of the rear shell of the product to be pressure-held for pressure holding. During pressure holding, the pressure can be adjusted by adjusting the height of the vacuum adsorption component 12.

[0027] In this embodiment, the vacuum adsorption assembly 12 includes a first support frame 121 and a plurality of vacuum nozzles 122 connected to the first support frame 121. A first lifting drive module 123 is connected to the support base 11, and the first support frame 121 is movably connected to the output end of the first lifting drive module 123. The height of the vacuum nozzles 122 on the support base 11 can be adjusted by driving the first lifting drive module 123. Further, first support vertical plates 124 are provided on the support base 11 on opposite sides of the first lifting drive module 123. First slide rails 125 are provided on the first support vertical plates 124, and the first support frame 121 is slidably connected to the first slide rails 125 via first sliders 126. By setting a structure in which the first sliders 126 and the first slide rails 125 cooperate with each other, the height adjustment process of the vacuum adsorption assembly 12 can be made more stable.

[0028] In a preferred embodiment, four vacuum nozzles 122 are connected to the first support frame 121, and the four vacuum nozzles 122 are arranged in a matrix array.

[0029] In this embodiment, the support plate assembly 13 includes a second support frame 131 and a support plate 132 connected to the second support frame 131. A transverse drive module 133 is connected to the support base 11, and a second lifting drive module 134 is movably connected to the transverse drive module 133. The second support frame 131 is vertically connected to the output end of the second lifting drive module 134. Multiple support plates 132 are combined to form a support plane for supporting the product to be pressure-held. The transverse drive module 133 drives the second lifting drive module 134, causing the second support frame 131 and the support plates 132 to move laterally closer to or further away from the vacuum adsorption assembly 12, thereby adjusting the size of the support plane. The second lifting drive module 134 drives the second support frame 131 to rise and fall, adjusting the height of the support plate 132, thereby adjusting the height of the support plane.

[0030] In this embodiment, a supporting horizontal plate 135 is movably connected to the transverse drive module 133, and a second supporting vertical plate 136 is connected to the supporting horizontal plate 135. The second lifting drive module 134 is connected to the supporting horizontal plate 135. A second slide rail 137 is provided on the second supporting vertical plate 136, and the second support frame 131 is slidably connected to the second slide rail 137 via a second slider 138. By setting a structure in which the second slider 138 and the second slide rail 137 cooperate with each other, the height adjustment process of the bearing plate assembly 13 can be made more stable.

[0031] In a preferred embodiment, the number of support plate assemblies 13 is four, and the four support plate assemblies 13 are arranged in pairs facing each other on the four sides of the vacuum adsorption assembly 12. The size of the support plane is adjusted by changing the distance between the two pairs of opposing support plate assemblies 13 through lateral driving.

[0032] In summary, the pressure-holding device for assembling display modules and back covers provided in the above embodiments includes a pressure-holding platform comprising a vacuum adsorption assembly connected to a support base and multiple support plate assemblies located outside the vacuum adsorption assembly. The vacuum adsorption assembly is vertically and vertically driven, and the support plate assemblies are vertically and horizontally driven. Thus, the height and size of the support plane formed by the combination of multiple support plate assemblies for supporting the product to be pressure-held are adjustable, making it applicable to display module products of various specifications, improving the versatility of the pressure-holding device, and reducing production costs.

[0033] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
