Manufacturing process of conductive heating anti-fog glasses

Abstract

The invention discloses a manufacturing process of conductive heating anti-fog glasses, which comprises the following steps: providing a cured resin substrate, cleaning and hardening; melting a high-conductivity non-metal oxide and a high-conductivity metal oxide by adopting vacuum ion sputtering, and then sputtering and attaching to the surface of the resin substrate to form a high-conductivity film layer; cutting and grounding the resin substrate through numerical control machining according to the size of a glasses frame, forming an annular groove through cutting in the end of the resin substrate by a drilling tool; winding a metal wire on the annular groove, and filling a conductive silica gel to seal the annular groove; and finally assembling the glasses frame, and installing thermistors connected with the metal wire and heating switches on the inner sides of glasses legs of the glasses frame. The surface of the resin substrate is plated with the high-conductivity film layer formed by mixing the non-metal oxide and the metal oxide, the high-conductivity film layer is matched with the conductive silica gel to be integrated to the heating circuit of the glasses frame, point contact type heating demisting is achieved, compared with coating layer antifogging function, the antifogging function is more durable, in addition, the heat resistance of the resin substrate is high, and the optical performance advantage of an anti-reflection film is reserved.

Description

Technical field [0001] The present invention belongs to the field of lens, in particular, to a manufacturing process of conductive heating anti-fog glasses. Background technique [0002] Glasses becomes a must-have accessibility tool in many people's daily lives, but there are still some problems in daily use, and have a certain impact on work and life. For example, in the cold winter, the glasses wearer will enter the room outdoors, and the glasses will immediately form a water mist, and the water mist problem needs to be solved by wiping. In addition, after the user wears a mask and scarf, everyday breathing is easily formed on the glasses. At present, there is a certain technique study for the formation of water mist, such as the use of anti-fog membrane layers, but this method is poor. In addition, the battery is powered on the glasses to achieve heating function. For the durability, damage resistance, and heat resistance of the wire, the heat resistance of the substrate ha...
