[0017] To further illustrate the technical means and effects of the present invention, the following is a detailed description in conjunction with the embodiments of the present invention and the accompanying drawings.

[0018] The present invention solves the technical problem by providing a multi-hole auxiliary positioning device for positioning and placing an LCD and a touch screen and cooperating with a vacuum pressing machine to bond the LCD and the touch screen. The multi-hole auxiliary positioning device comprises:

[0019] A bottom plate 1 is provided with at least one pad 10 for placing an LCD and having dimensions matching the LCD. The bottom plate 1 is also provided with a gasket 11 and an elastic element 12. The gasket 11 has a guide hole 110. The elastic element 12 is used to support the positioning plate 2 before lamination and to help reset the positioning plate 2 after lamination.

[0020] The positioning plate 2 is provided with a guide column 20 at the position corresponding to the gasket guide hole 110 of the positioning plate 2. The positions of the guide column 20 and the guide hole 110 are correspondingly arranged, and the guide column 20 is slidably arranged in the guide hole 110. The bottom end of the guide column 20 is provided with a gasket accommodating hole 200 for accommodating the gasket 11. The positioning plate 2 is provided with a hollow positioning groove 21 corresponding to the position of the pad 10. A plurality of limit blocks 210 are provided on the inner side of the positioning groove 21. The opposite sides of each limit block 210 form a first positioning groove. The first positioning groove matches the size of the pad 10 and is used to position the LCD. The side of the limit block 210 away from the pad 10 is provided with a step structure 211. The step structures 211 form a second positioning groove. The second positioning groove is used to place and position the touch screen, and its size matches the size of the touch screen.

[0021] The washer 11 is made of a wear-resistant material to prevent wear between the guide post 20 and the washer 11 .

[0022] The length of the guide column 20 is greater than the height of the elastic element 12 in the expanded state.

[0023] A concave component accommodating groove 22 is provided on the side of the positioning groove 21 , and the component accommodating groove 22 is used to accommodate electronic components on the touch screen.

[0024] An operating slot 23 is provided on the side of the positioning slot 21 , and the operating slot 23 is convenient for operation when placing or removing the LCD or touch screen.

[0025] In an embodiment of the present invention, two pads 10 are provided on the base plate 1, and correspondingly, two positioning grooves 21 are provided on the positioning plate 2, which can position and place two LCDs at a time. When in use, the guide columns 20 of the positioning plate 2 are first inserted into the gasket guide holes 110 on the base plate 1. At this time, the elastic element 12 supports the positioning plate 2 so that a gap is left between the positioning plate 2 and the base plate 1. Then the multi-hole auxiliary positioning device is placed in a vacuum pressing machine, and then the LCD is placed in the first positioning groove and placed on the pad 10. Then, the adhesive on the touch screen is removed and placed on the second positioning groove. The electronic components on the touch screen are adjusted so that they are placed in the component accommodating groove 22 on the side of the positioning groove 21. Finally, the vacuum pressing machine is started to draw vacuum, and then the pressure plate of the vacuum pressing machine is pressed down onto the positioning plate 2. The positioning plate 2 presses the touch screen downward toward the base plate 1 until the touch screen and the LCD are fully bonded.

[0026] The gasket 11 is made of Teflon.

[0027] The elastic element 12 is a spring. During the pressing process, the elastic element 12 is compressed. After the pressing is completed, the positioning plate 2 is reset under the action of the elastic element 12 .

[0028] The beneficial effect of the present invention is that the multi-hole auxiliary positioning device of the present invention can place and position multiple LCDs and touch screens at one time, thereby realizing the simultaneous bonding of multiple LCDs and touch screens, effectively utilizing the vacuum pressing time, improving product yield and production efficiency, and the device has a simple structure and is easy to operate.

[0029] It should be pointed out that the present invention is not limited to the above-mentioned implementation mode, and any simple modification, equivalent change and modification made to the above-mentioned embodiment based on the technical solution of the present invention by any technician familiar with the profession shall fall within the protection scope of the present invention.
