Description

[0001] LAMINATING MACHINE [0002]

The present invention relates to a laminator technique, and more particularly to a laminating apparatus for quickly and efficiently laminating sheet members of various sizes and film members of various sizes without the provision of a vacuum chamber.

Today, the manufacturing industry faces a serious shortage of labor force, and the manufacturing industry is easily polluting the environment. And there is a great influence on the conventional process and manufacturing operation mode. In terms of labor and operating costs, the manufacturing industry faces the pressure to shift from the labor-intensive industry to the technology-intensive manufacturing industry. Therefore, many manufacturers are adopting policies to hire foreign workers, either by moving their factories abroad or by increasing production costs. Some manufacturers are introducing automated production lines and modes to upgrade operating systems, reduce manufacturing costs, reduce manpower, shorten manufacturing time, and improve production efficiency.

 With the advancement of flat panel display technology, the new generation of products are evolving toward lightweight, thin, flexible and refracted surface features to provide consumers with more sophisticated electronic and electrical products. Therefore, it is desirable to provide a display such as a polarizing plate, an antireflection film, an optical film, a touch film or an upper film, a bottom film, a functional film, a package film, a protective film and a supporting film of a flexible active OLED structure on a liquid crystal panel The various films of construction have lighter features. As a result, it is more difficult to align such a light and thin film to prevent foaming or adhesion marks when laminated onto a substrate.

Figure 7 shows a conventional laminating apparatus for laminating a film member on a sheet member. As shown, the laminating apparatus includes a vacuum box A in the vacuum chamber A0, a laminating wheel A1 movably mounted in the vacuum chamber A0, a suction wheel A1 provided on the upper surface of the vacuum chamber A0, (A2), a non-aspiration zone (A3) around the aspiration zone (A2) and sealed with an adhesive or adhesive tape to prevent leakage, a screen type A suction platform A21 and an inhaler platform C located above the vacuum box A to suck the sheet member C1. A vacuum is generated in the vacuum chamber (A0) of the vacuum box (A) during laminating. However, it takes a long time to generate a vacuum in the vacuum chamber A0, and the non-suction area A3 of the vacuum box A must be sealed to prevent air leakage, complicating the laminating operation, And labor. In the laminating operation, the laminating wheel A1 is lifted up in the vacuum chamber A0 and abuts on the suction platform A21 in the form of a screen, thereby laminating the film member B onto the sheet-like workpiece C1 . When the film member B is thin and soft and the laminating wheel A1 is brought into contact with the film member B by raising the suction platform A21 in a screen form onto the sheet type workpiece C1, Can be transferred onto the sheet-like workpiece C1 or the film member B, and the sheet-like workpiece C1 is incomplete.

Figure 8 illustrates another conventional vacuum laminating operation mode. According to this design, the flexible membrane A01 is mounted on the bottom surface of the vacuum chamber A0 of the vacuum box A; The laminating wheel A1 is located below the flexible membrane A01; The suction zone A2 is defined on the opposed upper surface of the vacuum chamber A0; The non-sucking zone A3 is confined to the upper surface of the vacuum chamber A0 around the sucking zone A2 and sealed to prevent air leakage; A suction platform A21 in the form of a screen is mounted in the suction zone A2 to support the film member B for laminating; The inhaler platform C is positioned above the vacuum box A to move the sheet-like workpiece C1. Since the laminating wheel A1 is located outside the vacuum box A, the size of the vacuum box A can be minimized and the time for generating a vacuum in the vacuum chamber A0 is shortened. During the laminating operation, the laminating wheel A1 is operated to elevate the flexible membrane A01 relative to the suction platform A21 in the form of a screen to laminate the film member B onto the sheet-like workpiece C1. However, continually raising the laminating wheel A1 to give upward pressure to the flexible membrane A01 can easily damage the flexible membrane A01. Therefore, the flexible membrane A01 must be frequently replaced. Furthermore, attention must be continuously paid to the vacuum box (A) to hold the vacuum chamber (A0) in a vacuum state to prevent air leakage. Moreover, the screen mark of the suction platform A21 in the form of a screen is transferred onto the surface of the film member B or the sheet-like workpiece C1 to incomplete the sheet-like workpiece C1.

According to the above-described conventional vacuum laminating operation mode, in order to keep the vacuum chamber A0 of the vacuum box A in a vacuum state in order to prevent air leakage, the sealing state of the non-suction zone A3 around the suction zone A2 . The laminating wheel A1, the suction platform A21 in the form of a screen and the flexible membrane A01 in the vacuum chamber A0 outside or inside the vacuum chamber A0 can easily be damaged and the suction platform A21 are transferred onto the surface of the film member B or the sheet-like workpiece C1 to incomplete the sheet-like workpiece C1. Further, when the size of the sheet-like workpiece C1 is changed, the size of the suction zone A2 and the size of the non-suction zone A3 must be relatively changed at this time, and the vacuum chamber A0, Complicating the sealing operation of the non-suction area A3 so as to protect the laminating operation, the preparation of the laminating operation becomes troublesome and inconvenient. There are a number of problems to be solved in the practice of conventional vacuum laminating operations.

The laminating apparatus according to the present invention is capable of solving the problem of transferring screen marks without the need to reset mechanical parts when laminating sheet members and sheet-like workpieces of various sizes.
