Problems solved by technology

Since the polarizer is a membrane made of a flexible material, which has a certain curl value, it is difficult to realize the contact between the polarizer and the substrate by using the above-mentioned polarizer attaching device of the line attachment method. High-precision attachment, and it is easy to generate air bubbles during the attachment process

Embodiment 1

[0056] figure 1 It is a schematic diagram of the overall structure of the film sticking device in this embodiment. Such as figure 1 As shown, the film attaching device includes a film supply mechanism h, a substrate conveying mechanism, a film adsorption unit a, a substrate adsorption unit b, a film flattening unit c, a film protective film peeling unit d, a motion unit, Bit unit, vacuum unit e and control unit (not shown in the figure). Among them, the diaphragm adsorption unit a is used to adsorb the diaphragm 1, the substrate adsorption unit b is used to adsorb the substrate 2, the motion unit is used to drive the diaphragm adsorption unit and the substrate adsorption unit to move, and the control unit is used to control the movement process of the whole device. control.

[0057] Out of right figure 1 Considering the clarity, the image sensor mark capture unit f and the position adjustment unit g are in figure 1 is not shown in , while the vacuum unit e is in figure 1...

Embodiment 2

[0097] The difference between this embodiment and Embodiment 1 is that in this embodiment, in the membrane attachment method, the membrane 1 and the substrate 2 are directly surface-attached instead of surface-attached in a vacuum environment; correspondingly, this The film sticking device in the embodiment also does not have a vacuum unit.

[0098] Other steps and structures in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0099] It should be noted that the film in the present invention can be a three-dimensional polarizer or a film made of other flexible materials.

Abstract

The invention provides a diaphragm attaching method, which comprises the following steps of: A, unfolding a diaphragm flatly, and then conveying the diaphragm to a position opposite to a substrate; B, aligning the diaphragm and the substrate; and C, attaching the diaphragm onto the substrate in a surface contact mode. Correspondingly, the invention provides a diaphragm attaching device. According to the diaphragm attaching method and the diaphragm attaching device disclosed by the invention, high-precision attachment between the diaphragm made of flexible material and the substrate can be realized, and bubbles can not be produced easily in an attaching process.

Description

technical field [0001] The invention relates to a membrane attaching method and a membrane attaching device. Background technique [0002] The function of the film attaching device is to attach flexible materials such as film to the corresponding substrate (panel), such as the three-dimensional (3D) polarizer attaching device applied in the three-dimensional polarizing (Pattern Retarder) technology. [0003] At present, most of the polarizer attachment devices adopt the wire attachment method, and the attachment process is as follows: the substrate to be attached to the polarizer is placed on the horizontal platform, the polarizer to be attached is adsorbed on the adsorption table, and then Rotate the adsorption table so that it forms a certain inclination angle with the horizontal table, and at the same time make the edge of the polarizer adsorbed on the adsorption table be in line contact with the edge of the substrate on the horizontal table. At this time, fix the adsorpt...
