Embodiment 1

[0034] A method for disassembling a touch screen, comprising the steps of:

[0035] Step 1. Provide a touch screen to be disassembled and a heating device, put the touch screen into the heating device for heating; the touch screen includes multiple substrates bonded together with an adhesive; the adhesive has the property of being softened by heat;

[0036] Step 2. When the adhesive between the multiple substrates is heated and softened, use a wire to move in the gaps between the multiple substrates to separate the multiple substrates;

[0037] Step 3. Soak the separated multiple substrates in an organic solvent and take them out to remove the residual adhesive on the surfaces of the multiple substrates.

[0038] Wherein, the touch screen includes a capacitive touch screen and a resistive touch screen.

[0039] In this embodiment, the touch screen is a capacitive touch screen. In this embodiment, the multiple substrates include cover glass and ITO glass, or the multiple subs...

Embodiment 2

[0065] Such as figure 1 As shown, a heating device applied to Embodiment 1, the heating device includes a bottom plate 10, a side plate 20 connected to the bottom plate 10, a fixing groove 110 provided on the bottom plate 10, and a fixed groove 110 embedded in the side plate 20 The heating plate 210 on the top, the bottom plate 10 is not parallel to the side plate 20, the surface of the heating plate 210 is flush with the surface of the side plate 20; the fixing groove 110 is used for the touch screen fixed, and when the touch screen is set in the fixing groove 110 , the surface of the touch screen is attached to the surface of the heating plate 210 . The touch screen can be fixed by the heating device and quickly heated to a preset temperature, so that the adhesive is softened and multiple substrates in the touch screen are disassembled.

[0066] Optionally, the heating device is further provided with a power switch, and the power switch is used to control whether the heatin...

Abstract

The invention provides a method for disassembling a touch screen. The touch screen is heated by a heating device, and the touch screen comprises a plurality of substrates bonded together by an adhesive; and when the adhesive in the touch screen is softened by heat, a metal wire is used for moving in gaps of the multiple substrates to separate the multiple substrates, and the separated substrates are placed in an organic solvent to remove the adhesive remaining on the surfaces of the substrates. The method for disassembling the touch screen cannot scratch a cover lens of a body, can efficientlydisassemble the cover lens and ITO glass engraved with an ITO line, and can recover the cover lens and ITO glass without the residual adhesive.

Description

technical field [0001] The invention relates to the technical field of recycling electronic equipment, in particular to a method for disassembling a touch screen. Background technique [0002] Touch screen (touch screen), also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. The tactile feedback system can drive various connecting devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create vivid audio-visual effects through the liquid crystal display screen. [0003] According to the working principle of the touch screen and the medium for transmitting information, the touch screen is divided into four types, namely resistive touch screen, capacitive touch screen, infrared touch screen and surface acoustic wave touch screen. [0004] The capacitive touch screen is a composite glass screen. The inner surface and interlayer of the g...
