Problems solved by technology

[0007] In view of the dispensing pattern used in the dispensing method of the touch panel in the prior art, the dispensing line segment is too scattered so that the glue cannot spread in a short time, or the glue is not spread uniformly, resulting in bubbles during lamination. Provides a dispensing method for touch panels

Embodiment 1

[0056] This embodiment follows Figure 5 The dispensing pattern shown is for dispensing. In this embodiment, the room temperature during the experiment is 25°C, the dispensing pressure of the dispensing machine is 0.1Mpa, the moving speed of the needle of the dispensing machine is 80mm / s, and the dispensing volume The glue is 0.6g, the dispensing time is 58s, and the viscosity of the glue is 3000mPa·s. The angular value of the acute angle part a of the "X"-shaped dispensing pattern is 45°, and the angular value of the obtuse angle part b of the dispensing pattern is 150°. The measured diffusion time data is shown in Table 1 shown. It should be noted that the diffusion time involved in this article is defined as: the time from the moment the glue coated on the cover lens touches the touch screen 300 to the time when the glue spreads completely on the entire touch screen 300 .

Embodiment 2

[0058] In this embodiment, the room temperature during the experiment is 25°C, the dispensing pressure of the dispenser is 0.09Mpa, the needle moving speed of the dispenser is 80mm / s, the dispensing amount is 0.6g, and the dispensing time is 58s. The viscosity of the glue is 3000mPa·s. The angular value of the acute angle part a of the "X"-shaped dispensing pattern is 44°, and the angular value of the obtuse angle part b of the dispensing pattern is 149°. The measured diffusion time data is shown in Table 1 shown.

Embodiment 3

[0060] In this embodiment, the room temperature during the experiment is 25°C, the dispensing pressure of the dispenser is 0.095Mpa, the needle moving speed of the dispenser is 80mm / s, the dispensing amount is 0.6g, and the dispensing time is 60s. The viscosity of the glue is 3500mPa·s. The angular value of the acute angle part a of the "X"-shaped dispensing pattern is 43°, and the angular value of the obtuse angle part b of the dispensing pattern is 148°. The measured diffusion time data is shown in Table 1 shown.

Abstract

The invention provides a glue-dispensing method and pattern for a touch panel. Different from the design on the glue-dispensing pattern in the prior art, a glue-dispensing pattern in a shape similar to a hollow X is arranged on a touch screen, the glue-dispensing pattern is in an X shape as a whole and is distributed in a triangle around the touch screen to ensure that the inclusiveness of a blank area encircled by triangular glue-dispensing lines is enhanced, thereby ensuring glue to diffuse more uniformly. In addition, the position layout of the glue-dispensing lines of the X-shaped glue-dispensing pattern is more reasonable, which can ensure that the diffusion speed of the glue during dispensing the glue along the glue-dispensing lines in the glue-dispensing process is kept in balance, thereby avoiding sealing bubbles; and after the glue dispensing is finished, the glue diffuses towards the periphery from the central region of the touch screen, thereby ensuring that the diffusion speed is increased to a certain extent and further preventing bubbles from generating.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a glue dispensing method for touch panels. Background technique [0002] At present, consumer electronic equipment such as mobile communication equipment has entered the homes of ordinary people and has become an indispensable tool for more and more people in their daily life or work. At the same time, the touch screen structure has also been favored by more and more people. [0003] In general, the touch screen structure includes a cover lens (not shown in the figure), a touch screen 300', and an adhesive layer connecting the two. In the specific production process, UV glue or optical transparent glue is used between the cover lens of the touch screen panel and the touch screen to complete the lamination of the product. In the bonding process, the choice of dispensing pattern becomes an important factor in determining the length of bonding time and whether air bubbles will be gene...
