Embodiment Construction

[0026] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0027] like figure 1 As shown, the low-temperature dismantling method of the touch screen of the present invention mainly includes the following specific steps:

[0028] Step 100, setting a low-temperature freezing environment. The temperature of the low-temperature freezing environment is controlled at -40°C to -200°C; the low-temperature freezing environment is preferably a liquid nitrogen freezing solution, which has low temperature and stable properties, and is easy to control the low temperature range. Using an ordinary low temperature environment, usually the required freezing time is 1min-5min.

[0029] However, if the touch screen is placed in a liquid nitrogen freezer for freezing, the required freezing time is only 10s-30s, which greatly improves the disassembly speed, and th...

Abstract

The invention discloses a low-temperature disassembling method of a touch screen. The low-temperature disassembling method comprises the following steps of: S1, setting a low-temperature freezing environment so as to enable the temperature of the low-temperature freezing environment to be controlled in a range of -40 DEG C to -200 DEG C; S2, placing the touch screen into the low-temperature freezing environment; and S3, when all parts of the touch screen are separated, taking out all the parts. According to the low-temperature disassembling method of the touch screen, disclosed by the invention, the nondestructive and high-efficiency finished-product touch screen disassembling is realized by utilizing the different physical characteristics including different types of heat expansion and cold contraction, different phase-state conversion points and the like between glass and a rubber material through the low-temperature environment and the normal pressure. The low-temperature disassembling method disclosed by the invention can not scratch a glass panel of a body, and can efficiently disassemble the glass panel and a functional panel engraved with an ITO (Indium Tin Oxide) line, and no residual glue exists.

Description

technical field [0001] The invention relates to a dismantling method, in particular to a low-temperature dismantling method of a touch screen. Background technique [0002] Reducing costs and improving the utilization of raw materials have always been the leading direction for enterprises to improve their overall efficiency. In view of the design and structural characteristics of the existing resistive touch screen and capacitive touch screen, the efficiency of recycling the defective finished products has been very low. [0003] Especially for the glass panel (COVER LENS) of the capacitive screen, because the ink on it is easy to scratch, and the strong adhesion of the optical glue (OCA) and other characteristics, the reuse of the glass panel is basically zero under normal conditions. . The main difficulty lies in: the viscosity of the optical adhesive is very strong at room temperature, and it is basically difficult to separate the glass panel and the functional panel en...
