[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0025] A frame-sticking jig to solve the deformation of foam sticking, refer to Figure 1 , including a fixture body 10 and a double-sided adhesive foam 20 disposed in the fixture body 10, and a cover plate 30 to be bonded is disposed above the double-sided adhesive foam 20. The production process in this embodiment is changed from the original process of bonding the cover plate 30 with the display screen and the backlight before bonding the double-sided adhesive foam 20 to the cover plate 30, to bonding the double-sided adhesive foam 20 to the cover plate 30 before bonding the cover plate 30 with the display screen and the backlight.
[0026] Reference Figure 2 The fixture body 10 is provided with a fixing groove 11 for placing and fixing the double-sided adhesive foam 20. The fixing groove 11 is located in the middle of the fixture body 10. The fixing groove 11 is opened on the upper surface of the fixture body 10. The depth of the fixing groove 11 is adapted to the thickness of the double-sided adhesive foam 20. The fixture body 10 fixes the double-sided adhesive foam 20 in advance, and then performs a bonding operation with the cover plate 30, thereby ensuring that the double-sided adhesive foam 20 is not easily deformed during the bonding process.
[0027] Reference Figure 3The double-sided adhesive foam 20 includes a heavy release film 21, a foam body 22, and a light release film 23 arranged in sequence. The heavy release film 21 of the double-sided adhesive foam 20 is placed in the fixing groove 11 with one side facing downward. The heavy release film 21 is used to protect the foam body 22 that is not attached to the housing. After the cover plate 30 is fully attached to the display screen and the backlight, it needs to be assembled with the client housing. The heavy release film 21 is torn off when the cover plate 30 is assembled with the client housing. A first tear handle 211 extends outward from one side of the heavy release film 21, and the first tear handle 211 is used to facilitate tearing off the heavy release film 21.
[0028] Reference Figure 3 The foam body 22 is double-sided and adhesive, and the upper and lower sides of the foam body 22 are respectively adhered and fixed to the light release film 23 and the heavy release film 21, and the adhesion of the foam body 22 toward the heavy release film 21 is stronger than the adhesion of the foam body 22 toward the light release film 23. Therefore, the light release film 23 is easier to peel off.
[0029] Reference Figure 3 The light release film 23 is used to protect the foam body 22 that is not attached to the cover plate 30. A second tear handle 231 extends outward from one side of the light release film 23. The second tear handle 231 is used to easily tear off the light release film 23. When the double-sided adhesive foam 20 is accommodated in the fixing groove 11 and needs to be attached to the cover plate 30, the light release film 23 is torn off to attach the cover plate 30.
[0030] Reference Figure 4 A through hole 40 is provided between the heavy release film 21 and the foam body 22. The through hole 40 is used to avoid the display screen and the backlight to be subsequently attached to the cover plate 30. The through hole 40 passes through the upper and lower sides of the heavy release film 21 and the foam body 22, and the through hole 40 is located in the middle of the heavy release film 21 and the foam body 22. The through hole 40 allows the heavy release film 21 and the foam body 22 to avoid the display screen and the backlight, so as to facilitate the subsequent attachment of the cover plate 30 to the display screen and the backlight.
[0031] Reference Figure 4 A tear handle groove 12 is provided on the fixture body 10 at a position of the first tear handle 211 relative to the heavy release film 21. The tear handle groove 12 is connected to the fixing groove 11. The tear handle groove 12 is used to place the first tear handle 211, so that after the double-sided adhesive foam 20 is accommodated in the fixing groove 11, the first tear handle 211 is correspondingly placed in the tear handle groove 12. The tear handle groove 12 is not provided at a position of the fixture body 10 relative to the second tear handle 231, because when the double-sided adhesive foam 20 is fixed to the fixing groove 11 and adhered to the cover plate 30, the light release film 23 needs to be torn off.
[0032] Reference Figure 1 and Figure 2The fixture body 10 is provided with a cover plate platform 13, which is located on the upper surface of the fixture body 10, and the cover plate platform 13 is the position of the fixture body 10 outside the fixing groove 11. The cover plate platform 13 is used to place a cover plate 30, which is placed on the cover plate platform 13 and covers the entire fixing groove 11.
[0033] Reference Figure 1 and Figure 2 The cover plate platform 13 is provided with a plurality of clamping blocks 14 for fixing the cover plate 30. The plurality of clamping blocks 14 are evenly distributed along the circumferential direction of the cover plate 30. The plurality of clamping blocks 14 are used to fix the periphery of the cover plate 30 to position the cover plate 30. There are two clamping blocks 14 located at the two long side sections of the cover plate 30, and one clamping block 14 located at the two short side sections of the cover plate 30. The cover plate 30 is fixed to the cover plate platform 13 by the plurality of clamping blocks 14 to facilitate the fitting operation.
[0034] Reference Figure 1 and Figure 2 The fixture body 10 is provided with a pick-up and placement groove 15 on both sides relative to the cover plate 30, and the pick-up and placement groove 15 is used to facilitate the pick-up and placement of the cover plate 30. The pick-up and placement groove 15 is opened along the thickness direction of the fixture body 10, and the pick-up and placement groove 15 is connected to the fixing groove 11 and the outside.
[0035] Reference Figure 1 and Figure 2 The fixture body 10 is also provided with a fixing component for adsorbing and fixing the double-sided adhesive foam 20. The fixing component includes an air pipe port 16 opened on the side of the fixture body 10 and a plurality of air holes 17 opened in the fixing groove 11. The plurality of air holes 17 are evenly distributed at the position of the fixture body 10 relative to the fixing groove 11, and the plurality of air holes 17 are evenly distributed along the circumferential direction of the fixing groove 11. The plurality of air holes 17 are all connected to the inside of the fixing groove 11. The air pipe port 16 is located on the side of the fixture body 10, and the air pipe port 16 extends to the inside of the fixture body 10 and is connected to the plurality of air holes 17. The air pipe port 16 is used to connect an external air pipe to perform a suction operation on the plurality of air holes 17. After the double-sided adhesive foam 20 is fixed in the fixing groove 11, the air is sucked into the multiple air holes 17 through the air pipe port 16 connected to the external air pipe to adsorb and position the double-sided adhesive foam 20, so as to fix the double-sided adhesive foam 20 and reduce the difficulty of fitting between the double-sided adhesive foam 20 and the cover plate 30.
[0036] Reference Figure 4When the cover plate 30 and the double-sided adhesive foam 20 are bonded, the heavy release film 21 of the double-sided adhesive foam 20 is placed downward in the fixing groove 11, and the double-sided adhesive foam 20 is adsorbed through the plurality of air holes 17. By tearing off the light release film 23 and pressing the cover plate 30 downward onto the cover plate platform 13 to bond and fix it to the foam body 22, this bonding operation reduces the bonding difficulty of the double-sided adhesive foam 20 and has high bonding efficiency.
[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
