Description

Surface bonding device and bonding method thereof

technical field

The invention relates to a curved surface laminating device and a laminating method thereof, in particular, a curved surface can be formed around a flexible element in advance through the stretching deformation of a carrier film of a jig. To make the lamination industry more precise and accurate, and to achieve the effect of improving the qualification rate of manufacturing.

Background technique

According to this, the manufacturing industry is currently facing serious problems of shortage of labor demand, and processing operations are likely to cause pollution to the environment, and under the circumstances of rising environmental awareness, increased labor and operating costs, and labor-intensive transformation into technology-intensive pressure, Most of the industry relocates or introduces labor to cope with rising production costs, or use production line automation technology and fixture-assisted processing to improve operating conditions and reduce costs, so as to reduce manpower and save manufacturing hours. the purpose of increasing productivity.

In addition, due to the continuous research and development and improvement of the production technology of liquid crystal displays and thin film touch panels, the new generation of product applications are directed towards lighter, thinner, energy-saving, low-radiation, flexible or curved surfaces, and large-scale applications. The purpose of design is to provide human beings with a wider visual interface and higher-resolution colors, and bring great convenience and fun to human beings. Therefore, the display interface has become the focus of the industry, and relevant manufacturers have The company develops new display technologies and new applications, and works together to improve the visual enjoyment of human beings. However, because most of the LCD panels and touch panels are flat, the development of the panel bonding technology has been quite mature. Although Lamination technology is constantly improving, but it is also relatively difficult to have great innovation. However, as panel manufacturers develop new organic light emitting diode (OLED) flexible curved panel display technology, compared with traditional liquid crystal Panels have the advantages of wider viewing angle, better contrast, low power consumption and high response rate, so the development of curved surface bonding technology is an important key, and a method that can stably bond curved substrates must be found.

However, with the rapid growth of demand for liquid crystal displays and thin-film touch panels, how to improve production efficiency and yield is the expectation of all manufacturers. The bottleneck of the panel process is mainly in the coating and lamination process, such as polarizers, glass substrates , optical film, touch film, or the upper and lower films, functional films and encapsulation films of flexible active matrix organic light-emitting diode display panels, etc., will have strict requirements on their surfaces, and they will be placed between various two substrates. In lamination, optical glue with better light transmittance (OCR glue, commonly known as water glue) or solid optical glue (OCA glue) is often used for bonding, but generally the technology of gluing and pressing is easy to produce bubbles and the process takes a long time. And problems such as low pass rate, it is even more unable to meet the needs of large-size panels.

Therefore, manufacturers will use the following two methods to carry out the lamination operation. One of them is to use the stencil to adsorb on the substrate and move to the bottom of the other substrate, and then use the roller of the machine to press and roll on the mesh surface of the stencil. , so that the substrate is rolled onto another substrate and then combined into a whole, and the lamination process between the two substrates is in a vacuum state without generating air bubbles, so it will not cause the problem of optical refraction, so it can improve the qualification rate of the lamination process However, in the process of rolling the stencil, in order to make the substrate adsorbed by the stencil stick to another substrate, the roller will apply a large force to roll, causing the stencil to be easily affected by repeated use. Pulled and ruptured, the stencil broke the vacuum and could not be tightly adsorbed on the substrate, and the overall structure was quite unstable, which in turn affected the quality and pass rate of the panel lamination process, and it was difficult to meet the requirements of production capacity and cost.

In addition, there is another way of attaching the panel. First, the male mold is positioned with the substrate, and the curved panel is positioned under the female mold, and then the male and female molds are extruded to each other, so that the substrate is squeezed by the curved panel. In accordance with its curvature, the curved panel and the substrate are bonded as a whole. However, in the case of this manufacturing method, when the curved panel is pressed into the substrate, the surface of the substrate will be in contact with the curved panel. The point is prone to defects such as defects and damage due to excessive pressure on a single point, and the adhesive coated on the surface of the substrate is also prone to cutting and falling off from the curved section of the curved panel when the curved panel is pressed into the substrate. As a result, the curved panel and the substrate cannot be properly bonded to each other, or a part of the adhesive overflows outwards, which leads to an increase in the defect rate.

Therefore, how to meet the requirements of precise fit, improve the process qualification rate and production capacity, this is the direction that those engaged in this industry are eager to research and improve.

The utility of fitting job speed.

(2) The curved surface bonding device can perform the bonding operation of the curved surface object 4 and the soft element 5 in a vacuum environment. Because it is operated in a vacuum state, it is not easy to generate air bubbles during the bonding process. The problem of optical refraction will not be caused by air bubbles, which can improve the pass rate of the lamination process.
