Description

Technical Field

[0001] This utility model relates to the field of touch screen assembly technology, and in particular to an auxiliary tooling for applying optical films to touch screen assemblies. Background Technology

[0002] In existing display terminals, to achieve better display effects, an optical film is usually applied to the cover glass, such as an anti-glare optical film, an anti-reflective film, an anti-fingerprint film, etc. The normal bonding process is: applying the optical film to the front of the cover glass → applying OCA to the back of the cover glass → applying FOG. This process is called TLI bonding, followed by UV curing. The optical film is then exposed to ultraviolet light. Since FOG-TFT is black, UV curing cannot achieve the desired finish. FOG refers to mounting the FPC onto the glass panel; FOG stands for matte screen. UV curing enhances the wear resistance and durability of the OCA after bonding, giving it good UV resistance so it can withstand long-term exposure to ultraviolet light without color fading, degradation, or contamination. However, some customers specify optical film characteristics, such as low transmittance, high refractive index, and high haze. Using the above process steps in these cases will result in poor UV curing. The bonding process needs to be changed to: OCA on the back of the cover plate → FOG bonding → UV curing → optical film bonding on the surface of the cover plate. However, unlike bonding the optical film directly to a single cover plate, TLI bonding requires consideration of the FOG and the components on the FOG's FPC. When bonding the optical film, there are no auxiliary tools, the FOG is easily broken, and the components are easily scratched by the bonding mesh if they are not properly positioned or cleared, resulting in low yield and increased costs.

Next, in conjunction with Figure 1-3 ..., the structure of the auxiliary tool for attaching an optical film to the touch screen assembly according to the embodiment of the present application will be described in detail.

[0054] In an exemplary embodiment, (TLI, Touch Panel and LCM Integration), that is, the integration of the touch screen and the display screen, refers to the common touch screen assembly.

[0055] In an exemplary embodiment, the auxiliary tool for attaching an optical film to the touch screen assembly according to the embodiment of the present application is used to attach an optical film to the matte screen of the TLI fitting.

[0056] In an exemplary embodiment, the auxiliary tool for attaching an optical film to the touch screen assembly according to the embodiment of the present application includes: a bottom plate 101.

[0057] In an exemplary embodiment, a cover plate groove 102 is recessed on the upper surface of the bottom plate 101.

[0058] In an exemplary embodiment, the cover plate groove 102 is used to place the cover plate of the touch screen assembly.

[0059] In an exemplary embodiment, the depth of the cover plate groove 102 is determined according to the thickness of the cover plate. Usually, the depth dimension of the cover plate groove 102 is designed to be slightly shallower than the thickness of the cover plate. For example, when the cover plate thickness is 1.8 mm, the depth dimension of the cover plate groove 102 is 1.3 mm; this design is to expose the cover plate to facilitate the attachment of the optical film.

[0060] In an exemplary embodiment, a TFT groove 103 is further recessed in the cover plate groove 102.

[0061] In an exemplary embodiment, the TFT groove 103 is used to place the matte screen of the touch screen assembly

[0062] In an exemplary embodiment, suction holes 105 are provided on the TFT groove 103. There are multiple suction holes 105, and the multiple suction holes 105 are arranged in a "king" character, as Figure 1 shown.

[0063] In an exemplary embodiment, the suction holes 105 penetrate through the bottom plate 101, that is, the suction holes 105 communicate with the upper and lower surfaces of the bottom plate 101.

[0064] In one exemplary embodiment, the air intake 105 is, for example, a through hole with a diameter of 1.5 mm.

[0065] In one exemplary embodiment, the lower surface of the base plate 101 is recessed and provided with a rear cover groove.

[0068] In an exemplary embodiment, a cavity is provided between the back cover 201, the sealing ring 301, and the back cover groove; it can be understood that the sealing ring 301 not only serves the purpose of sealing, but also, due to the thickness of the sealing ring 301, creates a space between the back cover 201 and the back cover groove, which is the cavity.

[0069] In one exemplary embodiment, an air inlet 108 is externally connected to the base plate 101, and the air inlet 108 is disposed, for example, on the side of the base plate 101.

[0070] In one exemplary embodiment, the air inlet 108 connects to the chamber.

[0071] In one exemplary embodiment, the upper surface of the base plate 101 is further provided with an FPC clearance space 106, which is used to place the FPC of the matte screen.

[0074] In one exemplary embodiment, the projection of the back cover 201 on the base plate 101 covers the projection of the TFT slot 103 on the base plate 101.

[0075] In one exemplary embodiment, the projection of the back cover 201 on the base plate 101 covers the projection of the FPC clearance 106 on the base plate 101; it can be understood that because of the existence of the chamber, when the air inlet 108 is connected to an external air extraction device, the air inlet 105 directly adsorbs the matte screen, which facilitates the subsequent application of the optical film.

[0076] In one exemplary embodiment, the TFT groove 103 is rectangular.

[0077] In one exemplary embodiment, a corner clearance groove 104 is provided at the corner of the TFT groove 103. The corner clearance groove 104 is based on the existing TFT groove 103, which expands the corner area. This design avoids the occurrence of corner breakage of the matte screen when it is adsorbed.

[0078] In one exemplary embodiment, a protrusion is provided at the edge of the rear cover groove, and the protrusion is recessed into the surface of the base plate 101; that is, the protrusion is higher than the rear cover groove and lower than the rear surface of the base plate 101.

[0079] In one exemplary embodiment, the bump is disposed on the outside of the sealing ring 301.

[0080] In one exemplary embodiment, the back cover 201 has a protrusion 202 at the position corresponding to the protrusion.

[0081] In one exemplary embodiment, the protrusion 202 is provided with a fixing position 203, which is, for example, a hole.

[0082] In one exemplary embodiment, the back cover 201 is fixed to the back cover groove by the fixing position 203; it can be understood that the design of the protrusion avoids the phenomenon of compression of the chamber when the back cover 201 is installed, thus providing protection for the chamber.

[0083] In one exemplary embodiment, the bumps include a plurality of, such as Figure 2 and Figure 3 As shown.

[0084] In one exemplary embodiment, each bump is fitted with a protrusion 202.

[0085] In one exemplary embodiment, a plurality of bumps are distributed in a ring shape along the edge of the back cover groove.

[0086] In an exemplary embodiment, when using the touch screen assembly optical film application auxiliary tooling of this application embodiment, the matte screen is bonded to the TFT groove 103, and the FPC on the matte screen is placed in the FPC clearance position 106. The air suction device connected to the air inlet 108 is activated. Due to the existence of the chamber, the air suction device achieves adsorption of the touch screen assembly through the air inlet 108, the chamber, and the air suction hole 105. At the same time, due to the design of the FPC clearance position 106, the matte screen is prevented from being damaged. Moreover, due to the design of the FPC suction cup 107, which is connected to the chamber, the FPC can be firmly adsorbed in the FPC clearance position 106.
