Abstract
This utility model relates to a kind of LCD automatic beam change welding goggles, comprise UV optical filter, the first polaroid, a TN-LCD liquid crystal cell, the second polaroid, the 3rd polaroid, the 2nd TN-LCD liquid crystal cell, the 4th polaroid, pad element glass from top to bottom successively, first, second described TN-LCD thickness of liquid crystal box is 3 ~ 5 μm.The utility model has the advantages that: adopt the TN-LCD liquid crystal cell of high-quality and polaroid, filter set to be combined into sunshade lens; photoinduction system on eyeglass can the generation of arc light and disappearance when detecting electric welding instantaneously; rapid driving liquid crystal shading variable colors etc. are to reach filtering noxious light safely and effectively, thus the eye of protection welder, face avoid the injury of arc light radiation.The wear-type face shield integrated with safety helmet can be made as, liberate welder's both hands completely and ensure security protection.
Description
Technical field
This utility model relates to a kind of welder's goggles, particularly relates to a kind of LCD automatic beam change welding goggles.
Background technology
Eye protector for welder general is at present extremely dark eyeglass, and on welding worker band, it cannot see thing at a forearc.Therefore have to hand-held a protective eye lens or operation electric welder's helmet, another is held by electric welding handle.For avoiding strong arclight to the stimulation of eyes and damage, generally can not yet play forearc at welding rod close to workpiece and protective eye lens is buckled well.Its major defect has be can not vacate two handss simultaneously effectively operate at two: one, particularly larger on work high above the ground impact; Two is that blindly the starting the arc is welded by experience, makes up a deficiency initial solder joint more afterwards, affects welding quality, waste welding material and electric power.
Product common in the market can not all reach a grade in uniformity, optical dispersion, response speed, view angle dependency 4, and common is 1/1/1/2 and 1,/2/,1/1 two kind, cannot meet and protect order needs.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of LCD automatic beam change welding goggles, filtering noxious light safely and effectively, and the eye of protection welder, face avoid the injury of arc light radiation.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of LCD automatic beam change welding goggles, comprise UV optical filter, the first polaroid, a TN-LCD liquid crystal cell, the second polaroid, the 3rd polaroid, the 2nd TN-LCD liquid crystal cell, the 4th polaroid, pad element glass from top to bottom successively, first, second described TN-LCD thickness of liquid crystal box is 3 ~ 5 μm.
The distortion angle of first, second described TN-LCD liquid crystal cell is 70 ° ~ 80 °.
Described first ~ four polaroid singleton transmittance 42%-45%, degree of polarization more than 99%.
Described first ~ four polaroid absorbs axle and first, second 3 ° ~ 5 °, TN-LCD liquid crystal cell internal friction axle clamp angle.
Described protective eye lens is fixed on safety helmet.
Compared with prior art, the beneficial effects of the utility model are:
The TN-LCD liquid crystal cell of high-quality and polaroid, filter set is adopted to be combined into sunshade lens; photoinduction system on eyeglass can the generation of arc light and disappearance when detecting electric welding instantaneously; rapid driving liquid crystal shading variable colors etc. are to reach filtering noxious light safely and effectively, thus the eye of protection welder, face avoid the injury of arc light radiation.The wear-type face shield integrated with safety helmet can be made as, liberate welder's both hands completely and ensure security protection.In uniformity, optical dispersion, response speed, view angle dependency 4, index all rises to 1 grade, and effectively can control the cost of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-UV optical filter 2-first polaroid 3-the one TN-LCD liquid crystal cell 4-second polaroid 5-the 3rd polaroid 6-the 2nd TN-LCD liquid crystal cell 7-the 4th polaroid 8-pad element glass.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, a kind of LCD automatic beam change welding goggles, comprise UV optical filter 1, first polaroid 1, TN-LCD liquid crystal cell 2, second polaroid 3, the 3rd polaroid 5, the 2nd TN-LCD liquid crystal cell 6, the 4th polaroid 7, pad element glass 8 from top to bottom successively, first, second described TN-LCD liquid crystal cell 3,6 thickness is 3 ~ 5 μm, to improve the uniformity of whole picture.
Wherein, the distortion angle of first, second TN-LCD liquid crystal cell 3,6 is 70 ° ~ 80 °.First ~ four polaroid 2,4,5,7 singleton transmittance 42%-45%, degree of polarization more than 99%.First ~ four polaroid 2,4,5,7 absorbs axle and 3 ° ~ 5 °, first, second TN-LCD liquid crystal cell 3,6 internal friction axle clamp angle.Protective eye lens is fixed on safety helmet.
Utilize the liquid crystal cell that the principle of TN LCD is made, when on state of, liquid crystal molecules parallel is in the upper and lower base plate of glass, the distortion that liquid crystal molecule shape between upper and lower base plate is in 90 ° when black state.
Photoinduction system on eyeglass can the generation of arc light and disappearance when detecting electric welding instantaneously, drive rapidly liquid crystal shading variable color etc. to reach filtering noxious light safely and effectively, thus the eye of protection welder, face avoids the injury of arc light radiation.
