Abstract
The present invention relates to the labor protection device that a kind of electric welder uses, its structure comprises hand vice, face shield and corresponding electronic device, problem of slow response when making the electric welder's helmet observation window that this device has solved liquid-crystalline glasses effectively makes the more convenient and safety of workman's welding work pieces.
Description
The present invention relates to the labor protection device that a kind of electric welder uses.
Existing welding hood observation window adopts dark glass to make, and is invisible when arc light does not occur, and must hold face shield by left hand, on the cover, takes away observation when not welding during weldering, only can use very inconvenience with right hand-hold pincers operation; Past also some research worker liquid-crystalline glasses on probation do the face shield observation window, liquid-crystalline glasses is regulated by light, but because of the liquid crystal response speed slow (80～100 milliseconds) fail.
The object of the present invention is to provide a kind of electronic prtecting unit for arc welder easy to use, safe.
Task of the present invention is done in such a way that the face shield observation window adopts protection to adjust glass and liquid-crystalline glasses constitutes, and it opens and closes by being installed in the electronic oscillator control in the reception regulation device on the face shield; When welding, electronic oscillator is not worked, and liquid crystal is closed fully, avoids the stimulation of arc light to eye, can see solder joint clearly again, when stopping to weld, receives the electronic oscillator work in the regulation device, and liquid crystal is transparent fully, can clearly observe the solder joint situation; The startup of the reception regulation device on the face shield and to stop be controlled by the emitter on the hand vice, during welding, liquid-crystalline glasses always occurs closing the purpose of observation when having reached protection eyes and don't influence welding in preceding 0.3～0.5 second at electro-welding arc at every turn automatically.
Below in conjunction with drawings and Examples the present invention is described in detail.
Fig. 1 is an operation principle block diagram of the present invention.
Fig. 2 is the front view of hand vice of the present invention.
Fig. 3 is the front view of face shield of the present invention.
Fig. 4 is the profile of face shield of the present invention.
Structure of the present invention comprises hand vice (7), face shield (8) and corresponding electronic device, hand vice (7) are provided with induction coil (1) and emitter (2), emitter (2) transmits about about 1 meter of effective radius with ultrasonic or infrared ray or form of electromagnetic wave; The center of face shield (8) is observation window (10), it adopts protection to adjust glass (11) and liquid-crystalline glasses (12) constitutes, glass (11) is adjusted in protection the adjustment shade, anti-ultraviolet, thermal-radiating effect, the top of face shield (8) is provided with and receives regulation device (9), and it comprises receiver of remote-control sytem (3), photosensitive probe (4) and electronic oscillator (5).When welding rod and workpiece rigidly connect when touching, have greater than 30 amperes heavy current in the hand vice cable and pass through, but arc light does not occur as yet, this heavy current triggers emitter (2) by induction coil (1) and transmits (with ultrasonic or forms such as infrared ray or electromagnetic wave, about about 1 meter of effective radius), received by the receiver of remote-control sytem on the face shield (3), electronic oscillator (5) failure of oscillation, thereby liquid-crystalline glasses (12) is closed, and and then, arc light occurs, also can make electronic oscillator (5) failure of oscillation by photosensitive probe (4), make provision against emergencies emitter (2) or remote-controlled receiver (3) when malfunctioning, and injury electric welder's eyes increase safety coefficient.When stopping to weld, electronic oscillator (5) starting oscillation makes liquid-crystalline glasses (12) transparent fully, and the workman need not take off face shield can clearly observe the solder joint situation.
Problem of slow response when the present invention has solved liquid-crystalline glasses effectively and makes the electric welder's helmet observation window; during welding; liquid-crystalline glasses was always closed in the electro-welding arc appearance at every turn automatically in preceding 0.3～0.5 second; eyes had both been protected; and don't influence the situation of observing solder joint when welding, make the more convenient and safety of workman's welding work pieces.
Claims (2)
1, a kind of electronic prtecting unit for arc welder, its structure is hand vice (7) and face shield (8), it is characterized by hand vice (7) and be provided with induction coil (1) and emitter (2), the observation window (10) of face shield (8) center adjusts glass (11) with protection and liquid-crystalline glasses (12) constitutes, the top of face shield (8) is provided with and receives regulation device (9), and it comprises receiver of remote-control sytem (3), photosensitive probe (4) and electronic oscillator (5).
2, electronic protection device according to claim 1 is characterized by emitter (2) and transmits about about 1 meter of effective radius with ultrasonic or infrared ray or form of electromagnetic wave.
