Dipping liquid crystal welding goggle

The invention relates to an intelligent automatic dipping liquid crystal welding goggle which is based on DSP (Digital Signal Processing) control to simulate human eyes for sensitization, and comprises a control module, a light trigger module, a sensitization module, a manual setting module, an adjusting module and liquid crystal lenses. When the goggle is in use, relevant parameters of the dipping liquid crystal welding goggle are set through the manual setting module; during welding, a light intensity signal of welding arc collected by the light trigger module triggers the dipping liquid crystal welding goggle to work; and during the working process of the goggle, the sensitization module collects the intensity of the welding arc and transfers intensity information of the arc to the control module, the control module transmits a control signal to the adjusting module according to the intensity information of the arc received from the sensitization module and the parameter information set through the manual setting module, and the adjusting module adjusts the light transmittance of the liquid crystal lens according to the control signal received from the control module. The operating flexibility of welding personnel is improved simultaneously when the eyes of the welding personnel are protected.
