Dipping liquid crystal welding goggle

Abstract

Variable optical liquid crystal welding goggles include a control module (1), an optical trigger module (2), a photosensitive module (3), a manually setting module (4), a regulator module (5) and liquid crystal lenses (6). The manually setting module (4) is used to set related parameters of the variable optical liquid crystal welding goggles. When welding, the optical trigger module (2) receives the optical signal of the welding arc and triggers the control module (1); the photosensitive module (3) is used to capture the information of intensity of welding arc and send it to the control module (1); the control module (1) sends a control signal to the regulator module (5) basing on the information of intensity of welding arc received from the photosensitive module (3) and the parameters set by the manually setting module (4); the regulator module (5) adjusts the rate of light transmission of the liquid crystal lens (6) according to the received control signal. The variable optical liquid crystal welding goggles increase operative flexibility of the welders while protecting eyes of welders.

Description

technical field [0001] The invention belongs to the field of welding equipment, and relates to a welding goggle, in particular to an intelligent automatic dimming liquid crystal welding goggle based on DSP control and simulating the light sensitivity of human eyes. Background technique [0002] During the welding process, the welding arc light is strong, which will cause great damage to the eyes of the welding personnel. Therefore, the welding personnel must wear welding goggles during the welding process to avoid the damage of the arc light to the eyes. At present, the welding goggles used by welding personnel include ordinary welding goggles and automatic darkening welding goggles: ordinary welding goggles have a single color and cannot be dimmed, so it is not convenient for welding operations when worn; and automatic darkening welding goggles can be used according to The automatic dimming of the arc light solves the problem of ordinary welding goggles to a certain extent....

AI Technical Summary

Problems solved by technology

In the dark state, due to the set light transmittance is single, the farther the goggles are from the weld, the less clearly the weld can be seen, and the welder can only operate at close range, which greatly limits the flexibility of the welder's operation
