[0012] Compared with the prior art, the utility model provides a pressing fixture for a mobile phone screen, which has the following beneficial effects:

[0013] 1. For the pressing fixture of the mobile phone screen, the controller controls the cylinder to extend, the cylinder drives the moving plate to move downward, at this time the moving plate drives the sealing airbag to fit with the sealing frame to achieve sealing, at this time the extrusion surface on the pressing airbag extrudes the screen body to press it, during the pressure holding process, the controller controls the air pump to extract air, so that a vacuum cavity is formed between the moving plate and the placing table, thereby facilitating the elimination of bubbles between the screen body and the mobile phone body, and effectively improving the pressing effect of the mobile phone screen.

[0014] 2. For the pressing fixture of the mobile phone screen, the mobile phone body is limited by a plurality of limiting blocks, and the screen body is limited by the variable chamfer at the upper end. The variable chamfer can effectively ensure the fitting and extrusion of the pressing airbag and the screen body while limiting the screen body, thereby effectively improving the pressing effect of the mobile phone screen.

[0015] Parts not involved in this device are the same as or can be implemented by the prior art. The utility model is convenient for eliminating bubbles between the screen body and the mobile phone body, thereby effectively improving the pressing effect of the mobile phone screen.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1: Refer to Figures 1 - 4 , a pressing jig for a mobile phone screen, comprising: a pressing table 1, and further comprising: a placing table 103 disposed on the pressing table 1; a frame 101 fixedly disposed on the pressing table 1; a sealing frame 102 fixedly disposed on the pressing table 1, and the placing table 103 is disposed within the sealing frame 102; a moving plate 201 disposed on the upper side of the sealing frame 102, and the moving plate 201 is matched with the sealing frame 102; a pressing assembly disposed on the moving plate 201; cylinders 2 symmetrically disposed between the moving plate 201 and the pressing table 1; a controller 110 disposed on the upper side of the pressing table 1; an air extraction assembly for extracting the gas between the moving plate 201 and the pressing table 1.

[0023] A sealing airbag 202 cooperating with the sealing frame 102 is fixedly connected to the moving plate 201.

[0024] The air extraction assembly includes an air pump 109 fixedly disposed on one side of the pressing table 1. A cavity 106 is disposed within the pressing table 1. Air extraction ports 107 are symmetrically disposed on the placing table 103, and the air extraction ports 107 are communicated with the cavity 106. An air extraction pipe 108 is disposed between the air extraction end of the air pump 109 and the cavity 106.

[0025] The pressing assembly includes a pressing airbag 203 fixedly disposed on the moving plate 201. An extrusion surface 204 is disposed on the lower side of the pressing airbag 203.

[0026] When laminating the mobile phone screen, after the mobile phone body 3 and the screen body 301 are fitted to each other, they are placed on the placing table 103. The controller 110 is used to control the cylinder 2 to extend. The cylinder 2 drives the moving plate 201 to move downward. At this time, the moving plate 201 drives the sealing airbag 202 to fit with the sealing frame 102 to achieve sealing. At this time, the extrusion surface 204 on the lamination airbag 203 extrudes the screen body 301 to laminate it. During the pressure holding process, the controller 110 controls the air pump 109 to pump air, so that a vacuum cavity is formed between the moving plate 201 and the placing table 103, thereby facilitating the elimination of bubbles between the screen body 301 and the mobile phone body 3, and effectively improving the lamination effect of the mobile phone screen.

[0027] Embodiment 2: Refer to Figures 1 - 4 , a lamination jig for a mobile phone screen, which is basically the same as Embodiment 1. Further, a plurality of limiting blocks 104 are fixedly connected to the placing table 103. The limiting blocks 104 are matched with the mobile phone body 3, and a variable chamfer 105 matched with the screen body 301 is arranged on the limiting blocks 104.

[0028] The air extraction port 107 is arranged between two limiting blocks 104.

[0029] The mobile phone body 3 is limited by a plurality of limiting blocks 104, and the screen body 301 is limited by the variable chamfer 105 at the upper end. The variable chamfer 105 can effectively ensure the fitting and extrusion of the lamination airbag 203 and the screen body 301 while limiting the screen body 301, thereby effectively improving the lamination effect of the mobile phone screen.
