[0039] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0040] As shown in the background technology, currently, in the production process of touch screen adhesive backing products, the touch screen is clamped and the double-sided adhesive edge is positioned and attached. This results in the double-sided adhesive of the product being biased to one side, resulting in complaints from some high-demand customers.

[0041] In order to solve this technical problem, the utility model provides an adhesive backing fixture structure, which is applied to a touch display screen.

[0042] Specifically, please refer to Figure 1-Figure 7 , the adhesive backing fixture structure specifically includes:

[0043] A fixture 1, with a through hole 11 at the bottom of the fixture 1 for the touch screen SENSOR to avoid;

[0044] An opening groove 12 is provided at the top of the fixture 1 for inserting the touch screen 13, and the opening groove 12 is connected to the corresponding through hole 11 below;

[0045] A positioning element 3, which is disposed in the opening groove 12 and connected to the side wall of the fixture 1;

[0046] The positioning element 3 includes a positioning block 31 and a sliding portion 32 slidably disposed in the fixture 1 and connected to the positioning block 31. The sliding portion 32 is connected to a spring 33 connected to the fixture 1. The spring 33 can cause the positioning block 31 to contact the outer side of the touch screen 13 to form a support and positioning for the touch screen 13.

[0047] The supporting element 4 is disposed in the opening groove 12 and connected to the bottom wall of the fixture 1 , and the supporting element 4 is provided with a backing adhesive 5 for being attached to the touch screen 13 .

[0048] The adhesive backing fixture structure provided by the present invention realizes the positioning of the adhesive backing 5 by adding a supporting element 4 to the bottom wall of the fixture 1, and makes the adhesive backing 5 relatively stable and not easy to slide during the pasting process after positioning. The design of adding a positioning element 3 to the side wall of the fixture 1 can make the touch screen 13 maintain a relative center position through the interference of multiple positioning blocks 31 to correspond to the corresponding double-sided adhesive 51 below, thereby positioning both the adhesive backing 5 and the touch screen 13, thereby improving the accuracy of the adhesive backing fixture during attachment.

[0049] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0050] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0052] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a clamp structure for attaching adhesive backing, the clamp 1, a through hole 11 is opened at the bottom of the clamp 1 for the touch screen SENSOR to avoid; an open groove 12 is opened at the top of the clamp 1 for the touch screen 13 to be placed, and the open groove 12 is connected with the corresponding through hole 11 below; a positioning element 3 is arranged in the open groove 12 and connected to the side wall of the clamp 1; wherein the positioning element 3 includes a positioning block 31 and a sliding part 32 slidably arranged in the clamp 1 and connected to the positioning block 31, and the sliding part 32 is connected to a spring 33 connected to the clamp 1; under the action of the spring 33, the positioning block 31 can be pressed against the outer side of the touch screen 13 to form a support and positioning for it;

[0053] like Figure 4 and Figure 5 As shown, the positioning block 31 subjected to the force of the spring 33 will be exposed on the inner side of the fixture 1, so that the relative positioning space formed by the multiple positioning blocks 31 is slightly smaller than the size of the touch screen 13, so that when the touch screen 13 is dropped and placed in the opening groove 12, the positioning block 31 will be squeezed, and the positioning block 31 subjected to the squeezing force will slide toward the inside of the fixture 1 to cause the spring 33 to be compressed, and the compressed spring 33 will give the positioning block 31 a supporting force toward the outside, so that the touch screen 13 can be positioned and supported at the center position of the fixture 1 through the design of multiple springs 33, so as to improve the subsequent pasting accuracy with the adhesive 5;

[0054] The support element 4 is disposed in the opening groove 12 and connected to the bottom wall of the fixture 1, and the support element 4 is provided with a backing adhesive 5 for pasting on the touch screen 13;

[0055] There are four supporting elements 4 in this embodiment, and the four supporting elements 4 are respectively distributed at the four corners of the opening slot 12 and connected to the clamp 1;

[0056] Please refer to Figure 2 , Figure 6 As shown, the touch screen SENSOR is arranged at the bottom of the touch screen 13 and corresponds to the position of the through hole 11, and the adhesive backing 5 includes a double-sided adhesive 51, a release film 52 and a tear handle 53, wherein the double-sided adhesive 51 and the release film 52 are provided with a through groove 54 at the position corresponding to the supporting element 4;

[0057] The design of the release film 52 can protect the bottom surface of the double-sided adhesive 51, so that when it is placed in the opening groove 12 and waits to be contacted and pasted to the touch screen 13, no adhesion will be formed on the outside. After positioning and pasting, it can be easily taken out of the opening groove 12, and the tear handle 53 can be used to tear off the release film 52 when it needs to be pasted.

[0058] The adhesive backing fixture structure provided in Example 1 is further optimized. Specifically, Figure 4 As shown, the support element 4 includes an inner cylinder 41, an outer cylinder 42 and a support spring 43;

[0059] The inner cylinder 41 is slidably sleeved on the surface of the outer cylinder 42 and fixed to the clamp 1. The support spring 43 is connected to the bottom wall of the outer cylinder 42 and connected to the bottom end of the inner cylinder 41.

[0060] Under the action of the support spring 43, the relative state of the inner tube 41 and the outer tube 42 in the natural state is as follows: Figure 6 As shown, at this time, the height of the outer cylinder 42 exposed to the outside is greater than the thickness of the adhesive 5;

[0061] When the adhesive 5 is actually placed into the opening groove 12, the through groove 54 on the adhesive 5 needs to be aligned with the outer cylinder 42 in the plurality of supporting elements 4, so that the adhesive 5 passes through the through groove 54 and fits into the inside of the opening groove 12 to wait for alignment and pasting;

[0062] Through the above structural design, when the touch screen 13 slides into the opening groove 12 and sticks to the double-sided adhesive 51 in the adhesive backing 5, the touch screen 13 will first come into contact with the outer cylinder 42 below. After the touch screen 13 comes into contact with the outer cylinder 42, it can slide vertically toward the double-sided adhesive 51 under the guidance of the outer cylinder 42, thereby ensuring the accuracy of positioning.

[0063] The adhesive backing fixture structure provided in Example 1 or 2 is further optimized, such as Figure 1-Figure 7 As shown, the positioning element 3 further includes a receiving cavity 34, and the sliding portion 32 is slidably assembled with the clamp 1 through the receiving cavity 34. In a natural state, the positioning block 31 is exposed outside the receiving cavity 34 by the force of the spring 33;

[0064] A sloped platform 35 is formed on one side of the top of the positioning block 31 for guiding the touch screen 13 when it is pressed and inserted;

[0065] After the adhesive backing 5 is positioned by the supporting element 4 and placed in the opening groove 12, the touch screen 13 is placed toward the inside of the opening groove 12. During the placement of the touch screen 13, its bottom will first contact the inclined platform 35 on the positioning block 31. The inclined platform 35 subjected to the resistance force will make the positioning block 31 slide toward the inside of the accommodating cavity 34. During the continuous sliding process of the positioning block 31, the touch screen 13 is also continuously moving downward. When the positioning block 31 just slides to allow the touch screen 13 to pass through, the positioning block 31 stops sliding, and the outer side of the touch screen 13 after moving downward will contact one side of the positioning block 31, thereby forming a positioning effect on the touch screen 13.

[0066] There are eight positioning elements 3, and the eight positioning elements 3 form a group of two, which are divided into four groups in total;

[0067] The two positioning elements 3 in each group are respectively distributed on both sides of the corners of the opening slot 12;

[0068] Then the four groups of positioning elements 3 are respectively distributed at the four corners of the opening slot 12 .

[0069] In specific implementation, since multiple positioning elements 3 are distributed at different positions and angles, when multiple springs 33 jointly give a resistance force to the positioning block 31, the positioning block 31 subjected to the resistance force will jointly act on the touch screen 13, thereby ensuring that the touch screen 13 is located as close to the center of the clamp 1 as possible, thereby improving the accuracy of its attachment to the corresponding adhesive backing 5 below.

[0070] The adhesive backing fixture structure provided in Example 3 is further optimized. Figure 1 As shown, the support element 4 also includes a rubber support sheet 44 fixed to the top end of the outer cylinder 42;

[0071] The cross section of the rubber support sheet 44 is a trapezoid. The trapezoidal design allows the adhesive backing 5 to be well guided when it is sleeved in the support element 4 through the groove 54, thereby facilitating the placement of the adhesive backing 5.

[0072] An avoidance groove 14 is also provided on the clamp 1 at a position corresponding to the tear handle 53;

[0073] In Example 3, when the touch screen 13 located on one side of the positioning block 31 continues to move downward, the downwardly moved touch screen 13 will contact the corresponding rubber support sheet 44 below. Through the action of the rubber support sheet 44, the soft contact protection of the touch screen 13 can be guaranteed, and at the same time, it will form a transmission with the outer cylinder 42 below, so that the outer cylinder 42 slides toward the inner cylinder 41 and compresses the support spring 43, finally making the downwardly moved touch screen 13 aligned and attached with the double-sided adhesive 51 below.

[0074] The use process of the adhesive backing fixture structure provided by the utility model is as follows: first, the adhesive backing 5 with the through groove 54 is passed through the top end of the outer cylinder 42 on the supporting element 4 and placed in the bottom of the open groove 12 and in contact with the fixture 1. The position of the adhesive backing 5 can be positioned by multiple supporting elements 4 so that it is located at the center of the fixture 1. Then, the touch screen 13 is placed in the open groove 12 and pressed downward, so that one side of the multiple positioning blocks 31 is in contact with the outer side of the touch screen 13 together, thereby forming the positioning of the touch screen 13. Then, the touch screen 13 is continued to be pressed downward, so that the touch screen 13 contacts the outer cylinder 42 and conflicts with it. Finally, the positioned touch screen 13 is adhered to the positioned double-sided adhesive 51 below, thereby completing the adhesive backing attachment operation.
