A production leveling device for anti-warping of light guide film

Abstract

The invention provides a production leveling device for anti-warping of a light guide film, which includes a fixed support mechanism, a sliding support mechanism and a tension detection mechanism arranged oppositely. The tension detection mechanism is arranged on the surface of the light guide film, and a A driving mechanism that drives the sliding support mechanism to slide. In the present invention, the driving mechanism installed on the fixed support mechanism drives the sliding support mechanism to slide, so that the sliding support mechanism drives the guide shaft to move relative to the rolling shaft, and the tension detection mechanism is used to detect the tension of the light guide film, so that the light guide film The surface tension is in a reasonable range. Through the combined use of the infrared signal transmitter and the infrared signal receiver, the precise level detection of the light guide film is realized. The height of the guide shaft is adjusted by the lifting component to ensure that the light guide film is in a horizontal state. , to prevent the light guide film from being damaged and warped, to ensure the quality of the light guide film, the structure design is reasonable and simple, and it is easy to use.

Description

technical field [0001] The invention relates to the field of light guide films, in particular to a production leveling device for preventing warpage of light guide films. Background technique [0002] The light guide film dots are generally processed on the light guide plate by injection molding, hot pressing or printing. However, traditional injection molding and injection molding are difficult to realize the thin film design of the light guide plate. The current method of preparing the light guide film is gradually becoming more integrated. Design, one-step molding, simplifying the preparation process of light guide film and saving costs, so extrusion molding is the preferred way to prepare light guide film. [0003] Chinese invention patent CN207224639U discloses a light guide film production equipment, including a feeding port, a melting and stirring area, a stirring blade, a punching head, a first polygonal rolling shaft, a controller, a guide wheel, and a second polygo...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a production leveling device for anti-warping of the light guide film, which solves the problem that the sliding grinding block is not stable due to the insufficient level of the light guide film when the light guide film is converted from a vertical state to a horizontal state during the transmission process. The light guide film is damaged and warped, or the surface tension of the light guide film changes, which can easily cause the light guide film to be damaged and warped, which greatly reduces the quality of the light guide film.
