Automatic light-transforming blinkers for welding operation

Abstract

The invention relates to automatic light-transforming blinkers for welding operation, and relates to blinkers. The automatic light-transforming blinkers for the welding operation can automatically transform light according to light intensity on operation sites during welding operation to protect eyes effectively. The automatic light-transforming blinkers are provided with a glass frame, glass tips, an eyeglass and an automatic light-transforming device, wherein the automatic light-transforming device is provided with a frame cover, light filters, liquid crystal light valve plates and a photoelectric control circuit; the frame cover is connected with the glass frame; the light filters and the liquid crystal light valve plates are arranged on the frame cover; the light filters are positioned behind the eyeglass and face the internal surface of the eyeglass; the liquid crystal light valve plates are positioned behind the light filters and face the internal surfaces of the light filters; the photoelectric control circuit is provided with a photoelectric sensor, a control circuit and a direct-current power supply; the photoelectric sensor is arranged on the glass frame; a probe of the photoelectric sensor is exposed and faces the internal surface of the eyeglass; the signal output end of the photoelectric sensor is connected with the signal input end of the control circuit; and the signal output end of the control circuit is connected with the signal input ends of the liquid crystal light valve plates.

Description

technical field [0001] The invention relates to a kind of goggles, in particular to a kind of automatic dimming glasses for protecting eyes during welding operation. Background technique [0002] During traditional welding operations, the operator generally needs to hold a mask or wear a mask on his head, and frequently uses mechanical actions to move the lens or mask, which cannot completely free his hands, and will also affect the welding quality and work efficiency, and the cost is also high. [0003] The utility model patent whose notification number is CN201806839U discloses a kind of electric welding protective glasses. A mirror frame, a mirror frame and a lens are arranged, and the lens is composed of two parts. The main part of the lens is a black goggle lens, and a brown or plain transparent or translucent part is arranged at the lower part of the middle position. In the utility model electric welding protective glasses, the lens can be molded at one time by a two-...
