Detailed ways

The utility model and its beneficial effects will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

The structure when the touch screen 10 and the liquid crystal display 20 of a mobile terminal such as a mobile phone or Pad are bonded is shown in Figure 1. It can be seen from Figure 1 that the length of the touch screen 10 is greater than the length of the liquid crystal display 20, so both sides of the touch screen 10 There is a section that is not covered by the liquid crystal display 20 .

As shown in Figures 2 and 3, the device for disassembling the touch screen and liquid crystal display provided by the utility model includes a positioning plate 1 and a pressing plate 2;

The positioning plate 1 is provided with an accommodating groove 3 for accommodating the touch screen 10 and the liquid crystal display 20 and a clamping device for clamping the touch screen 10 . The portion covered by the screen 20.

A suction device 5 for suctioning the liquid crystal display 20 is arranged on the pressing plate 2 .

In this embodiment, the clamping device is set as a quick clip 4 , of course, the clamping device can also be set as a spring clip or other clip body with a clamping function.

As shown in Figure 4, the quick clip includes a base 41, a handle 42 and a clamping portion 43, the handle 42 and the clamping portion 43 are hingedly connected with the base 41, and the hinge shaft of the handle 42 and the base 41 and the clamping portion 43 and the hinge axis of the base 41 are the same hinge axis. When in the unclamped state, both the handle 42 and the clamping portion 43 are in an upward state, and there is a certain angle between them (as shown in FIG. 2 ). When the handle 42 is pressed down, due to the coaxial transfer relationship between the two, the clamping part 43 turns downwards along the direction opposite to the handle 42 until the handle 42 and the clamping part 43 are stretched to be in the same straight line. At this time, the clamping part The lower end of the holding portion 43 is in contact with the touch panel 10 .

The base 41 is screwed to the positioning plate 1, which is convenient for installation and disassembly.

The clamping part 43 clamps the clamping column 44, and the clamping column 44 is fixedly connected with the clamping part 43 by a nut 45. By adjusting the extension length of the clamping column 44 at one end of the clamping part 43, it is convenient to make The utility model is applied to the disassembly of touch screens 10 and liquid crystal display screens 20 with different thicknesses.

At least one end of the clamping portion 43 is provided with an elastic pressing block 46 to prevent the quick clamp from causing damage to the surface of the touch screen 10 .

The adsorption device 5 is configured as a suction cup, and when the pressing plate 2 is pressed against the positioning plate 1 , the suction cup is located in the accommodating groove 3 . The suction cup can provide a vacuum for adsorption, so that the touch screen 10 and the liquid crystal display 20 can be easily disassembled, thereby effectively ensuring the yield rate of the disassembled touch screen 10 and the liquid crystal display 20, so as to avoid excessive force caused by human beings. Cause damage to the touch screen 10 and the liquid crystal display 20 .

One side of the pressure plate 2 and one side of the positioning plate 1 are connected by a hinge 6. This connection structure makes it easy to realize the opening and closing of the pressure plate 2 and the positioning plate 1, and at the same time ensures that when the pressure plate 2 is closed, the suction cup is positioned on the liquid crystal display. The position directly above the screen 20, and preferably located in the central area of the liquid crystal display 20. In this embodiment, there are two suction cups.

In this embodiment, there are at least two clamping devices, and the clamping devices are disposed around the receiving groove 3 , and when the pressing plate 2 is pressed against the positioning plate 1 , the pressing plate 2 is located between the clamping devices. In this embodiment, four clamping devices are provided, which are respectively located at the four corners of the positioning plate 1 .

In this embodiment, the shape of the pressing plate 2 is "convex" and the shape of the positioning plate 1 is "concave". When the pressing plate 2 is closed, the pressing plate 2 just covers the liquid crystal display 20 or the left There is a part of the area not covered by the pressing plate 2 , in other words, the width of the pressing plate 2 (the length of the side where the bottommost horizontal line of the “convex” shape) is less than or equal to the length of the liquid crystal display 20 .

During actual operation, the touch screen 10 and the liquid crystal display 20 are first heated to melt the glue used for bonding between them. Then the touch screen 10 and the liquid crystal display screen 20 are placed in the accommodating groove 3, and then the handle 42 is pressed down, so that the handle 42 and the clamping portion 43 are stretched to be in the same straight line, and the elastic pressing block 46 is pressed against the touch screen 10. Then close the pressure plate 2, the sucker on the pressure plate 2 absorbs the liquid crystal display 20, and then open the pressure plate 2, the liquid crystal display 20 is adsorbed on the pressure plate 2, and the touch screen 10 is fixed on the Positioning plate 1, so as to realize the disassembly of touch screen 10 and liquid crystal display 20, the operation is very simple, convenient and fast, and the disassembly efficiency is high.
