Embodiment Construction

[0037] In the embodiment of the content of the present invention, the step of turning over the optical film is carried out between the cutting step and the grinding step of the optical film, and the optical film can be cut when the protective film is facing up, and the grinding can be done when the release film is facing up The optical film can avoid the problem of peeling off the release film from the optical functional film, and can improve the yield of the finished optical film; furthermore, the optical film can be turned over by the turning device, and it can also be achieved that it will not be damaged due to turning The effect of optical film or damage to the edge of optical film. The composition proposed in the embodiment is for the purpose of illustration, and is not intended to limit the scope of protection of the content of the present invention. Those with ordinary knowledge can modify or change these components according to the needs of actual implementation.

Abstract

The invention discloses a turnover device and a method for manufacturing an optical film using the same. The turnover device comprises a base and a gripping mechanism. The clamping mechanism is used for clamping a diaphragm, and the gripping mechanism is rotatably mounted on the base. The clamping mechanism comprises two clamping members and a driving element, wherein the clamping pieces have at least a first lateral face, and the first side faces the diaphragm. The driving element drives at least one of these clamping members to move so that the diaphragm is interposed between the clips.

Description

technical field [0001] The content of the present invention relates to a flipping device and a manufacturing method of an optical film using the flipping device. Background technique [0002] During the production process of polarizers, the polarizers are sent to the cutting machine along the conveyor belt for cutting, and then grinded to smooth the edges of the polarizers. However, once an abnormality occurs during the cutting and grinding process, it will increase the rework cost of defective products. Contents of the invention [0003] The content of the present invention relates to a flipping device and a manufacturing method of an optical film using the flipping device. In an embodiment, the step of turning over the optical film is carried out between the cutting step and the grinding step of the optical film, and the optical film can be cut when the protective film is facing up, and the optical film can be ground when the release film is facing up, then It can avoi...
