[0002] At present, most TP manufacturers use OCA technology for touch screen bonding, and it is a general trend for water glue bonding to replace OCA technology. The performance of water glue bonding is generally better than OCA adhesive, with high light transmittance and good quality, especially for medium and large size and high sensitivity capacitive screens, its cost price is better than OCA. At present, most touch screen bonding adopts traditional manual bonding, which has the advantage of being compatible with touch screens of different sizes, but the disadvantage is that the operation is complicated, it is difficult to control the amount of glue, and it is difficult to remove excess glue.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 to Figure 2 As shown, a touch screen glue bonding device includes a base 1, an upper vacuum adsorption platform device 2, a lower vacuum adsorption platform device 3, a first slide rail device 4, a second slide rail device 5, a third slide rail device 6, a cylinder device 7, a first glue dispensing needle tube 8, and a second glue dispensing needle tube 9.

[0027] The base 1 includes components such as a servo motor and a power switch, which provide support.

[0028] The upper vacuum adsorption platform device 2 and the lower vacuum adsorption platform device 3 are both composed of an adsorption platform 12, a vacuum generator 13 and an air inlet 14. One end of the vacuum generator is connected to the compressed air, and the other end is connected to the adsorption platform 12. The adsorption method includes: injecting compressed air into the air inlet 14 of the adsorption platform 12, so that the touch function sheet 10 or the cover glass 11 can be adsorbed on the adsorption platform 12, and closing the air inlet valve, so that the touch function sheet 10 or the cover glass 11 or the touch screen assembly can be removed.

[0029] The first slide rail device 4 is arranged on the base 1 and connected to a cylinder device 7 for moving forward and backward. Automatic operation is achieved through the cylinder device 7. The lower vacuum adsorption platform device 3 is installed on the first slide rail device 4.

[0030] The second slide rail device 5 is arranged on the rear side of the base 1 and is connected to a cylinder device 7 for moving left and right. Automatic operation is achieved through the cylinder device 7. The first dispensing needle tube 8 and the second dispensing needle tube 9 are correspondingly installed on the second slide rail device 5.

[0031] The third slide rail device 6 is arranged on the right side of the base 1 and is connected to a cylinder device 7 for moving up and down. Automatic operation is achieved through the cylinder device 7. The upper vacuum adsorption platform device 2 is installed on the third slide rail device 6.

[0032] The first glue dispensing needle tube 8 and the second glue dispensing needle tube 9 are marked with scale lines, so that the glue amount can be accurately controlled by the scale line glue dispensing needle tube.

[0033] A touch screen glue bonding method, using the above touch screen glue bonding device, the steps are as follows:

[0034] The first step: placing the touch function sheet 10 on the lower vacuum adsorption platform device 3 , fixing the touch function sheet 10 by drawing vacuum, and adsorbing the cover glass 11 on the upper vacuum adsorption platform device 2 .

[0035] Step 2: Move the lower vacuum adsorption platform device 3 to the first glue dispensing needle tube 8 through the first slide rail device 4, and the first glue dispensing needle tube 8 moves left and right through the second slide rail device 5 to spread the glue all over the touch function sheet 10.

[0036] Step 3: Use the second glue dispensing needle 9 to fill the edge of the touch function sheet 10 with silicone rubber. The rubber has high hardness and is not easy to flow, which can effectively control the glue on the touch function sheet 10 from flowing out and effectively control the thickness of the glue layer.

[0037] Step 4: After the glue is applied, move the lower vacuum adsorption platform device 3 to its original position, move the upper vacuum adsorption platform device 2 downward to the designated position through the third slide rail device 6, open the upper vacuum adsorption platform device 2, lower the cover glass 11 to make it fit on the touch function sheet 10 covered with glue, open the lower vacuum adsorption platform device 3, and remove the pasted touch screen.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
