The utility model relates to an electronic automatic light-adjusting goggle for welders, which belongs to the welding equipment. The electronic automatic light-adjusting goggle for welders is composed of a power supply battery, and an oscillation boosted circuit, a chargeable large electrolytic condenser, a photodiode, a trigger, a gate circuit IC1, a normally-opened liquid crystal display, etc. which are connected with the power supply battery, wherein, the power supply battery properly makes use of a solar cell; the output end of the trigger is connected in parallel with the other gate circuit IC2; the output end of the gate circuit IC2 is connected with a normally-closed liquid crystal display; the normally-opened liquid crystal display and the normally-closed liquid crystal display are arranged in one side frame in superposition. The utility model has the advantage of adjustable light transmittance, can be automatically adjusted by ambient light or welding light, and is charged by the welding light. The electronic automatic light-adjusting goggle for welders has high light transmittance before arc welding, so a welder can clearly see an object in the field of vision. The electronic automatic light-adjusting goggle for welders has low light transmittance after arc welding, so the welder can only see electric arcs and work-pieces. The utility model can effectively avoid eye scalding during welding, and has a good field of vision after welding. The electronic automatic light-adjusting goggle for welders can be used in various electro-gas welding.
Description
Technical field
This utility model belongs to welding equipment technical field, more particularly relates to the improvement that is installed in the welding goggles on the electric welder's helmet.
Background technology
Electric welder's helmet and the welding lens that is installed on it are the bead and arclight the burning to human body of splashing when preventing electric welding.The ultraviolet light that electric arc sends is very strong.For avoiding damaging eyes, existing filter lens for arc welding is brown or dirty-green sunglasses.Welding current is big more in general, selects for use the color of eyeglass should be dark more, and the electric arc light penetration is also just more little.But existing filter lens for arc welding exists major defect, and its light transmittance is non-adjustable.Therefore, after the welding starting the arc, set at the photograph of strong arclight, the welder can see workpiece, soldering turret and environment etc. clearly.And before the welding starting the arc, under natural lighting, welder's the visual field is intercepted by deep-color lens, and is often pitch-dark at the moment, can only grope operation, and inconvenience is dangerous.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, provides a kind of light transmittance adjustable, and can be regulated automatically by ambient lighting; Light transmittance is very high before the welding starting the arc, and the welder can know the object of seeing clearly in the visual field; Light transmittance is very low after the welding starting the arc, and the welder can only see electric arc and workpiece clearly, can effectively avoid damaging the electronic type welding goggles with an automatic light meter of eyes.
Summary of the invention
In order to achieve the above object, this utility model is connected the photodiode that negative pole is connected with the trigger input, the trigger that input is connected with the photodiode negative pole, the gate circuit IC1 that input is connected with the outfan of trigger, the liquid crystal display of often opening of AND circuit outfan connection by supplying cell, the audion oscillation step-up circuit that is connected the battery two ends, the chargeable big electrochemical capacitor that is connected oscillation step-up circuit two outfans, anodal positive pole with big electrochemical capacitor and constitutes.
When supplying cell was solaode, available arclight charged to it.Power savings is fairly obvious, and with welding with filling, need not charge separately separately, and is very convenient.
The outfan of trigger can also and connect another gate circuit IC2 again.The input of IC2 is connected with the outfan of trigger, and outfan is connected with a normally closed liquid crystal display.Often open with normally closed liquid crystal display is overlapping together and be installed in the frame.Photodiode is installed on its limit.Remaining circuit side mounted thereto.
This utility model is work like this: arclight irradiation solaode produces electric energy.Raise through the 3V voltage of audion oscillation step-up circuit, inject big electrochemical capacitor and store to its charging with solaode.Simultaneously, under the arclight irradiation, the photodiode conducting.The voltage that raises adds to trigger through photodiode and makes its output high level.Trigger trigger gate IC circuit 1, the output square wave is supplied with and is often opened liquid crystal display.Often open liquid crystal display and close rapidly, light transmittance reduces greatly, plays the effect of protection eyes.Simultaneously, trigger output high level is given gate circuit IC2, but not output of IC2.Normally closed liquid crystal display is still closed, and light transmittance is still very low.So, during welding job, often open liquid crystal display and normally closed liquid crystal display is all closed, light transmittance is very low, and eyes obtain good protection.Otherwise, stop to weld when not having illumination, often open liquid crystal display and open, the welder has the good visual field.Even do not have at solaode under the situations such as electricity or damage, normally closed liquid crystal display still can play the effect of protection eyes.
This circuit, is reliably stablized as the rechargeable battery storage of electrical energy with big electrochemical capacitor, and can reach decades service life.Big electrochemical capacitor replaces rechargeable battery, can also be according to the color depth of the automatic regulator solution crystal display of welding light intensity.The speed of capacitor charge and discharge is very fast, not limited by voltage.During light intensity (as electric welding light), the electric energy that solaode produces is many, and the voltage of big electrochemical capacitor is just high, and the color of often opening liquid crystal display is darker, light transmittance is lower.When light is weak (as gas welding light), the electric energy that solaode produces is few, and the voltage of big electrochemical capacitor is just low, often open liquid crystal display of light color, light transmittance is just high.Just can regulate automatically.
This utility model light transmittance is adjustable, and can be regulated automatically by surround lighting or welding light, by the charging of welding light.It is very high to have welded the forearc light transmittance, and the welder can know the object of seeing clearly in the visual field; Light transmittance is very low after the welding starting the arc, and the welder can only see electric arc and workpiece clearly.The eyes of burning when it can effectively avoid welding, stopping postwelding has the good visual field again.Can be widely used in the various electrogas weldings.
