Abstract

Automation darkening mask, the sight line of welder is hindered for the filter glass not allowed on mask, welder is remained to see clearly the situation of welding position in the environment of insufficient light, this invention takes following technical measures：Photoelectric sensor, electromagnet are installed on mask and form is provided with, photoelectric sensor connection filter glass controller, filter glass controller is connected and controls electromagnet；Filter glass, filter glass connection electromagnet and the keying by magnet control filter glass to form are installed in activity on form；Present invention place unlike the prior art is：It employs the method control filter glass of machinery, before welder carries out welding job（Play forearc）Filter glass is moved away from form when not needing protect eyes.At this moment the unattenuated light for reaching welder's eyes of filter glass, form is fully transparent, to the visual field of welder and work without a bit influence, overcomes the deficiency of the electric welder's helmet decay ordinary ray under prior art.

Description

Automation darkening mask

Technical field

The invention belongs to a technical field of labour protection particularly eye protection.

Background technology

A kind of that electric welding can all produce strong arc light, the eyes of this arc light meeting grievous injury welder.It is this person Come up with it is various be welded work in protect eyes method.In these methods, with the most use is installed additional on mask Filter glass installs the controllable liquid crystal display of transparency additional on the basis of infrared, ultraviolet filtering eyeglass, makes it automatic beam change Mask.Both masks have different application methods, and the former will take away after current interruption, otherwise, due to the transparency of filter glass It is too low that welder will be made whatever to can't see, cannot work at all.Although the latter can automatically recover certain transparency after current interruption, It is not necessarily intended to take away, but because the transparency recovered is not high, and due to filter glass and the various reasons of liquid crystal display, make weldering The serious colour cast of image that work is seen.All these can all have a strong impact on the routine work of welder, particularly in insufficient light Place, this influence makes the welding job cannot be normally carried out, and is unacceptable.

The reason for producing above-mentioned situation is all to have fixedly mounted filter glass on electric welding eye-mask under present technology And/or liquid crystal display, transmission of these things to light has different degrees of decay, while these decay are not full spectrum , so seeing that any object is all not only dark but also colour cast by it, the image of colour cast can equally make troubles to welder.The opposing party Face, welder usually carries out welding job in the back side of machine, bottom or the not enough place of illumination.In these local works, even if The weldment that not wearing a mask will see clearly at one's side is all not easy, if the decay along with eyeglass to light, then welder with regard to substantially without Method works.The fact is in the prior art that this is due to optical filtering no matter can all influence the sight line of welder using any mask The property of piece or liquid crystal display is determined that their own cannot be avoided, the deficiency of this also indented material.

The content of the invention

For filter glass or liquid crystal display the decay ordinary ray not allowed on mask（Light during the non-starting the arc）Hinder welder Sight line, welder is remained to see clearly the situation of welding position in the environment of insufficient light, arranged this invention takes following technology Apply：Photoelectric sensor, electromagnet are installed on mask and form is provided with, photoelectric sensor connection filter glass controller filters Eyeglass controller is connected and controls electromagnet；Filter glass is installed in activity on form, and filter glass connects electromagnet and by electricity Magnet controls keying of the filter glass to form.

Present invention place unlike the prior art is：It employs the method control filter glass of machinery, enters in welder Before row welding job（Play forearc）Filter glass is moved away from form when not needing protect eyes.At this moment filter glass does not wane and reduces to Up to the light of welder's eyes, form is fully transparent, and the visual field and work to welder overcome existing skill without a bit influence The deficiency of the electric welder's helmet decay ordinary ray under art.It is at once logical when photoelectric detector detects arc light when welding job is carried out Filter glass controller and solenoid actuated filter glass are crossed, form is blocked by filter glass.Whole process is just something like photograph The mechanical shutter of camera, rapid action is strong arc light by that just can make arc into the eyes of welder after the filtering of optical filtering Light can not injure welder.

Specific embodiment

" filter glass is installed in activity on form " described herein refers to remove to fixedly mount optical filtering on the form of mask It is all of to make the mounting means of filter glass activity shielding window outside piece.The mounting means of this function can be realized various It is various, for example it is hinged, push-and-pull move etc., they are suitable for the present invention and use, while the technique effect of the application can be produced.

In " filter glass connects electromagnet and the keying by magnet control filter glass to form " described herein, Filter glass has varied with the connected mode of electromagnet, for example, have these connected modes such as connecting rod connection, wiring connection all Can realize by magnet control filter glass to the keying of form, be suitable for this programme and use, and identical skill can be obtained Art effect.

Structure of the invention is：Photoelectric sensor, electromagnet are installed on mask and form is provided with, photoelectric sensor connection Filter glass controller, filter glass controller is connected and controls electromagnet；Filter glass, optical filtering are installed in activity on form Piece connects electromagnet and the keying by magnet control filter glass to form.

Form 5 is opened on mask is easy to welder to observe welding process and other work, and photoelectric sensor is installed on mask It is the generation for detecting arc light.Filter glass 4 is installed in activity on form 5, and this example is specifically filter glass 4 by filtering Eyeglass hinge 3 is hinged on the adjacency of form 5, and one end of connecting rod 1 is hinged on filter glass 4 by hinged shaft of connecting rod 2, connecting rod 1 The other end is hinged on the dynamic iron of electromagnet 6.Back-moving spring 7 is housed, the elastic force of back-moving spring 7 is pushed away by connecting rod 1 on electromagnet Dynamic filter glass 4 is around the rotating opening of filter glass hinge 3.Filter glass 4 is pulled around filter by connecting rod 1 during electromagnet energization adhesive Light eyeglass hinge 3 is rotated closes form 5, as shown in Figure 1.

The course of work of the invention, in general, the elastic force of the back-moving spring 7 on electromagnet is promoted by connecting rod 1 Filter glass 4 is rotated around filter glass hinge 3, filter glass 4 is in the state of opening.Therefore at this moment form 5 is not any Block, be fully transparent, so, even the environment of insufficient light, mask does not interfere with the work of welder yet, realizes this hair Bright target；When welder is welded, the photoelectric sensor on mask detects the arc light of hindering eye and this signal Filter glass controller is sent to, after filter glass controller receives this signal and treatment, is filtered by solenoid actuated at once Eyeglass 4 closes form 5.So arc light cannot directly reach the eyes of welder, reach the purpose of the eyes of protection welder.
