The present invention provides a device capable of adsorbing curved objects and a bonding device using the same, in particular, a lower static holding device and an upper static holding device are respectively disposed on the surface of the lower adsorption platform and the upper adsorption platform, which can be used not only It absorbs curved objects and can be bonded in a vacuum environment to meet the requirements of precision bonding process.

According to the current situation, the manufacturing industry is facing serious shortages of labor demand, and the processing operations are likely to cause serious pollution to the environment. In the case of high environmental awareness, labor and management costs, and labor-intensive transformation into technically intensive pressures. Most of the operators are responding to the increase in production costs by means of industrial shifts or the introduction of foreign workers, or by using the production line automation technology and the tool-assisted processing mode to improve the management quality and reduce costs, thereby reducing manpower and saving manufacturing. The purpose of increasing production capacity during working hours.

Furthermore, due to the continuous development and advancement of liquid crystal display and thin film touch panel manufacturing technologies, the new generation of products are oriented toward lighter, thinner, energy-saving, low-radiation, flexible or curved surfaces and large-sized directions. Design, the purpose is to provide humans with a wider visual interface and higher resolution colors, and bring great convenience and fun to humans. Therefore, the display interface has become the focus of industry attention, the relevant manufacturers are not Betting resources develop new display technologies and new applications, and work together to enhance the visual enjoyment of human beings.

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 bonding processes, such as polarizing plates and glass substrates. , optical film, touch film, or flexible active matrix organic light-emitting diode display panel upper and lower film, functional film and packaging film, etc., have strict requirements on its surface, and between various substrates For the bonding, optical glue (commonly known as water gel) or solid optical glue (OCA glue) with good transparency is often used for bonding, but the technique of applying rubber and re-compression is easy to produce bubbles, and the process time is long and good. The problem of low rate is even more difficult to cope with the demand for large-sized panels. Therefore, most of the manufacturers are laminating in a vacuum environment, and the stencil is adsorbed on the substrate and displaced to the bottom of another substrate, and then the roller of the machine is on the net. Pressing and rolling on the mesh surface of the board, the substrate is rolled onto the other substrate and integrated into one body, and the bonding process between the two substrates is in a vacuum state, no bubbles are generated, and no light is caused. Learning the problem of refraction, so the yield of the bonding process can be improved. However, in the process of rolling the stencil, the roller will exert a large effect in order to make the substrate adsorbed by the stencil adhere to another substrate. The rolling force causes the stencil to be easily pulled and ruptured under the repeated use of the stencil, which causes the stencil to be vacuumed and cannot be closely adhered to the substrate, and the overall structure is rather unstable, thereby affecting the quality and goodness of the panel bonding process. Rate, it is difficult to meet the requirements of capacity and cost.

Since the general LCD panel, touch panel, etc. are mostly flat, the development of the panel bonding technology has been quite mature. Although the bonding technology is continuously improved, it is relatively difficult to have great innovation technology, but with the panel. Manufacturers have developed new organic light-emitting diode (OLED) flexible surface panel display technology, which has wider viewing angle, better contrast, lower power consumption and higher reaction rate than traditional liquid crystal panels. The development of the bonding technology is an important key. It is necessary to find a way to stably adsorb the curved substrate to achieve precise fit, improve process yield and productivity.

And improve the yield of the product.

The secondary object of the present invention is that the device for adsorbing curved objects can be further applied to the working machine, and the lower adsorption platform and the upper adsorption platform are respectively disposed in the lower vacuum chamber and the inner chamber of the upper vacuum chamber.
