Automatic optically-controlled thickness adjusting system and method for producing electrically-controlled dodging membrane

Abstract

The invention relates to an automatic optically-controlled thickness adjusting system and a method for producing electrically-controlled dodging membranes. The equipment comprises an upper sheet placing roller, a lower sheet placing roller and a bearing roller that are connected with a composite roller; a sizing roller is arranged between the upper sheet placing roller and the composite roller; an ultraviolet irradiating box, a traction roller, an optical detecting box and a finished sheet rewinding roller that are sequentially arranged behind the composite roller; a rolling shaft of the composite shaft is provided with a roller spacing helical trimmer that is controlled by a motor; and a visible light transmissivity detector which can indicate the roller spacing helical trimmer is arranged between the ultraviolet irradiating box and the traction roller. The automatic optically-controlled thickness adjusting system and the method for producing electrically-controlled dodging membraneshave the benefits of automatically tracking the thickness change of the membrane layer, achieving the aims of quickly adjusting the roller spacing and correcting the inferior rate and waster possibility caused by excessively large or small thickness of the liquid crystal layer of the membrane in real time by the prearranged control software, and greatly improving the production efficiency, standardization and automation degree.

Description

technical field [0001] The invention relates to the field of production of electronically controlled light-controlling films, in particular to an automatic light-controlling thickness adjustment system and method for the production of electronically controlled light-controlling films. Background technique [0002] Electronically controlled dimming film, also known as intelligent dimming film, is a new type of technological material, which consists of two layers of ITO-PET film materials (the ITO surfaces of the two are opposite each other) and a liquid crystal mixture between the two It is composed of layers, and the finished product is made by uniform gluing, rolling, and ultraviolet curing. It has extremely high requirements on production precision, and the thickness and dimension error can reach the micron level. The current production method is often to determine the thickness first, and then pull the diaphragm step by step for processing and production. However, with ...

Problems solved by technology

However, with the wear and tear of the equipment and the limitations of the existing equipment manufacturing and processing conditions, it is really difficult to accurately adjust the top roller and composite roller to the same thickness effect every time during the production process.

Once the two sets of rollers, especially the composite rollers, deviate by a few millimeters, there will be obvious differences in the light transmittance and uniformity of the product, resulting in more defective or waste products.
