Embodiment Construction

[0010] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with specific embodiments.

[0011] The invention relates to a bonding process of a touch screen, which includes a casing and a touch screen. Before the touch screen is bonded to the casing, the bonding surface of the touch screen is roughened, and then the touch screen is bonded to the casing by an adhesive.

[0012] The commonly used method of rough treatment is corona treatment. Adhesives often use double-sided tape.

[0013] Corona treatment is widely used for surface treatment of plastics, paper and metal foils to improve the adhesion of inks, paints, adhesives and coatings. It is widely used because of its good effect, controllability and ease of mastering. Especially because the efficiency and effect of corona treatment equipment are constantly improving, keeping pace with high-y...

Abstract

The invention relates to an adhering technology of a touch screen. The adhering technology adopts a machine casing and the touch screen, before the touch screen and the machine casing are adhered, the adhering surface of the touch screen is roughly processed, and then a bonding agent is adopted to enable the touch screen to be bonded on the machine casing; the rough processing adopts corona processing which comprises the following steps: placing the touch screen between a discharger and a corona roller, and generating a corona between the discharger and the corona roller by utilizing a high-frequency high-voltage power supply, so as to form a low-temperature plasma region; through air ionization between two poles, generating ozone, and changing the molecular structure of the plastic surface of the touch screen. so that the molecular structure is converted into polarity from nonpolarity, small uneven holes are formed in the surface of a material after the corona treatment to enable the surface to be roughened, and further the surface activity is improved. According to the adhering technology disclosed by the invention, before the touch screen is adhered, the adhering surface of the touch screen is subjected to rough processing, the wettability and the adhesiveness can be changed, the adhesiveness of the touch screen and the machine casing is improved, and the adhering quality of a product is ensured.

Description

technical field [0001] The invention relates to a touch screen of an electronic product, in particular to a bonding process of a touch screen. Background technique [0002] For electronic products, such as mobile phones, the base material of the touch screen is PET. PET is a composite substance containing one or more polymers and various additives, such as fillers, antioxidants, lubricants, antistatic agents, pigments, etc. Although the chemical structure (group) of the main polymer of the plastic determines the wettability and adhesion of the primer, its additives will migrate from the interior of the plastic to the surface, affecting the surface energy of the plastic. Therefore, the longer the PET is stored, or the higher the content of certain additives (such as lubricants), the greater the change in its surface energy. [0003] The connection between the touch screen and the casing is usually bonded with double-sided tape. However, due to the lack of an effective area...
