Description

Laminating Device {LAMINATING MACHINE}

TECHNICAL FIELD The present invention relates to laminator technology, 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 installation of a vacuum chamber.

Today, the manufacturing industry is facing serious labor shortages, and the manufacturing industry is easily polluting the environment. It is of great interest and has a major impact on conventional process and manufacturing operating modes. In terms of labor and operating costs, the manufacturing industry is faced with the pressure to change from a labor intensive industry to a technology intensive process industry. Therefore, many manufacturers have a policy of relocating their factories overseas or hiring foreign workers to meet the increasing pressures of production costs. Some manufacturers are introducing automated production lines and modes to upgrade operating systems, reduce manufacturing costs, reduce manpower, reduce manufacturing time, and improve production efficiency.

 With the development of planar display technology, a new generation of products is evolving towards lighter, thinner, flexible and refracted surface features to provide more sophisticated electronic and electrical products to consumers. Therefore, a display such as a polarizing plate, an antireflection film, an optical film, a touch film or a top film, a bottom film, a functional film, a package film, a protective film, and a support film of a flexible AMOLED structure on a liquid crystal panel can be used. The various films of the composition have lighter features. As a result, it is more difficult to align such light and thin films to prevent the occurrence of bubbles or adhesive marks when laminating onto a substrate.

7 shows a conventional laminating apparatus for laminating a film member on a sheet member. As shown, the laminating apparatus is provided on a vacuum box A having a vacuum chamber A0 formed therein, a laminating wheel A1 movably mounted in the vacuum chamber A0, and an upper surface of the vacuum chamber A0. Suction zone A2, non-suction zone A3 sealed around the suction zone A2 and sealed with adhesive or adhesive tape to prevent leakage, and mounted to the suction zone A2 to engage the film member B It consists of a screened suction platform (A21), an inhaler platform (C) located above the vacuum box (A) to suck the seat member (C1). During lamination a vacuum is created in the vacuum chamber A0 of the vacuum box A. However, creating a vacuum in the vacuum chamber A0 takes a lot of time, and the non-suction zone A3 of the vacuum box A must be sealed to prevent air leakage, complicating the laminating operation and taking a lot of time. And labor. In the laminating operation, the laminating wheel A1 is raised in the vacuum chamber A0 to abut the suction platform A21 in the form of a screen, thereby laminating the film member B onto the sheet-like workpiece C1. . The film member B is thin and soft, so that when the laminating wheel A1 raises the screen-like suction platform A21 onto the sheet-like workpiece C1 and contacts the film member B, the screen-shaped suction platform A21 Screen marks) can be transferred onto the sheet-like workpiece C1 or the film member B, making the sheet-like workpiece C1 incomplete.

8 shows 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 at the opposite upper surface of the vacuum chamber A0; The non-suction zone A3 is defined on the upper surface of the vacuum chamber A0 around the suction zone A2 and sealed to prevent air leakage; The suction platform A21 in the form of a screen is mounted to the suction zone A2 to support the film member B for laminating; The inhaler platform C is located 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, which shortens the time for generating a vacuum in the vacuum chamber A0. During the laminating operation, the laminating wheel A1 is operated to raise the flexible membrane A01 relative to the suction platform A21 in the form of a screen to laminate the film member B on the sheet-like workpiece C1. However, continuing to raise the laminating wheel A1 to apply an upward pressure on the flexible membrane A01 can easily damage the flexible membrane A01. Therefore, the flexible membrane A01 must be replaced frequently. Moreover, attention must be paid to the vacuum box A to keep the vacuum chamber A0 in a vacuum state to prevent air leakage. Moreover, the screen marks of the suction platform A21 in the form of a screen are transferred onto the surface of the film member B or the sheet-like workpiece C1, so that the sheet-like workpiece C1 is incomplete.

According to the conventional vacuum laminating working mode described above, the sealed state of the non-suction zone A3 around the suction zone A2 to keep the vacuum chamber A0 of the vacuum box A in a vacuum state to prevent air leakage. Should take a look. The laminating wheel A1, the suction platform A21 in the form of a screen and the flexible membrane A01 outside or inside the vacuum chamber A0 of the vacuum box A can be easily damaged and the suction platform in the form of a screen ( The screen marks of A21 are transferred onto the surface of the film member B or the sheet-like workpiece C1 so that the sheet-like workpiece C1 is incomplete. Moreover, when the size of the sheet-like workpiece C1 is changed, at this time, the size of the suction zone A2 and the size of the non-suction zone A3 must be changed relatively, and the vacuum chamber A0 for air leakage Complicating the sealing operation of the non-suction zone A3 to protect the, the preparation of the laminating operation is complicated and inconvenient. In the practice of conventional vacuum laminating operations, there are many problems that need to be improved.

The laminating apparatus according to the present invention is intended to solve the problem of screen mark transfer without resetting mechanical parts when laminating sheet members and sheet-shaped workpieces of various sizes.
