Abstract
A liquid crystal welding mask is provided to solve the problem that the color depth of an eyeglass of the prior welding mask can not be changed. The mask consists of a light sensor, a controller, the liquid crystal eyeglass and a mask body, which is characterized in that a window on the mask body is provided with the liquid crystal eyeglass. The light sensor is connected with an input end of the controller and an output end of the controller is connected with an electrode of the liquid crystal eyeglass. The light sensor is influenced by the light of the welding spot and changes the color depth of the light crystal eyeglass by controlling the output voltage. When the weld is not done, the light crystal eyeglass presents undertint and the user can see the status of the welding spot. When the weld is done, the light crystal eyeglass presents high color which filters the glare and protects eyes.
Description
This utility model belongs to safety device, is a kind of electric welder's helmet.
Existing electric welder's helmet, its eyeglass are a kind of sunglasses of constant depth.Though can filter high light, when electric welding is not carried out, can not see the situation for the treatment of solder joint clearly.
This utility model purpose is to provide a kind of electric welder's helmet that can change the sunglasses degree of depth according to ambient light intensity.
This utility model is by mask body, eyeglass, and controller, optical sensor are formed, and the window of mask body is provided with liquid crystal lens, and optical sensor is connected the controller input, and controller output end is connected on the electrode of liquid crystal lens.The light intensity of pad makes the corresponding voltage of controller output by optical sensor, makes liquid crystal lens change color depth.
Advantage of the present utility model is: the color depth of liquid crystal lens is by the light intensity control of solder joint, and when not welding, color depth is shallow, can see the situation for the treatment of solder joint clearly, after the welding beginning, darkens, and light is filtered the protection eyes.
The utility model is described in further detail in conjunction with the accompanying drawings according to embodiment below.
Fig. 1 is a structure chart.Wherein 1 is optical sensor; The 2nd, controller; The 3rd, liquid crystal lens; The 4th, mask body.Optical sensor, controller, liquid crystal lens are arranged on the mask body.
Fig. 2 is an electrical schematic diagram of the present utility model.

3Constitute bleeder circuit.When not welding, T is subjected to intensity of illumination little, and the angle of flow is little, and its colelctor electrode is high potential, and the end of oppisite phase current potential of voltage comparator ic is higher than in-phase end, the IC output low level, and liquid crystal lens YJP two ends are owing to low level is light color.When the welding beginning, T is subjected to intensity of illumination big, and it is big that the angle of flow becomes, and IC end of oppisite phase current potential is descended, and is lower than in-phase end, and IC exports high level, and filter high light owing to high level is dark at liquid crystal lens YJP two ends, the protection eyes.
Claims (2)
1 one kinds of liquid crystal electric welder's helmets are made up of mask body, liquid crystal lens, optical sensor, controller, it is characterized in that the window of mask body is provided with liquid crystal lens.
2 liquid crystal electric welder's helmets as claimed in claim 1 is characterized in that optical sensor is connected the controller input, and controller output end is connected on the electrode of LCD panel.
