In order to be illustrated more clearly in the technical scheme of this utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.Wherein:
Fig. 1 is the structural representation with the automatic welding protective eye lens of self-checking function described in the utility model.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with Figure of description.
Set forth a lot of detail in the following description so that fully understand this utility model, but this utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when this utility model intension, and therefore this utility model is by the restriction of following public specific embodiment.
Secondly, alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of this utility model.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
As shown in Figure 1, this utility model provides a kind of automatic welding protective eye lens with self-checking function, and it comprises, and can respond to incident ray power thus optical signal be changed into the photosensitive device 100 of signal of telecommunication output; The signal of telecommunication that photosensitive system sends can be received, and carry out judging current duty according to the described signal of telecommunication, then export the control device 200 of corresponding signal according to the result judged and current ambient temperature; And, can the signal that sends of receiving control system, and realize according to this signal the eyepiece device 300 that light and shade changes.
Photosensitive device 100 comprises light sensitive diode, when unglazed photograph, and now light sensitive diode cut-off; When being subject to illumination, saturated reverse leakage current increases, and form photoelectric current, it changes with the change of incident intensity, thus is used for detecting the state of arc light in welding.Light sensitive diode and semiconductor diode are structurally similar, and its tube core is a PN junction with photosensitive feature, has unilateral conduction, need add backward voltage when therefore working.During unglazed photograph, there is very little saturated reverse leakage current, i.e. dark current, now light sensitive diode cut-off.When being subject to illumination, saturated reverse leakage current increases greatly, and form photoelectric current, it changes with the change of incident intensity, thus can be used for detecting the state of arc light in welding.Two light sensitive diodes are placed, the change of arc light during for detecting welding before eyepiece device 300; At two light sensitive diodes of placement below of eyepiece device 300, for the self-inspection of welding mask; After light sensitive diode changes optical signal into the signal of telecommunication, carry out by signal condition unit the interface amplifying and send into after filtering control device 200.
Eyepiece device 300 is transparent in normal state, and when its two ends add voltage, the liquid crystal molecule of the LCD panel inside of eyepiece device 300 starts distortion and rotates, and makes LCD panel from appearance by bright dimmed, and can realize different shade number effects when institute's making alive is different.Control device 200 controls the change of eyepiece device 300 both end voltage by driver element by PWM mode.
When ambient temperature is different; under same voltage, the dark-state degree of eyepiece device 300 also can be different; so employ temperature sensing unit in this utility model, temperature information is sent in control device 200, thus carries out corresponding compensation with the good protection ensured user eyes.
Flash cell is used for controlling flashing for several times by control device 200 before welding goggles uses, and is undertaken detecting and controlled eyepiece device 300 simultaneously transferring dark-state to by bright state by light sensitive diode.In the process, whether normally control device 200 can judge light sensitive diode and eyepiece device 300, can measure the response time of this face shield simultaneously, thus complete process of self-test.If self-inspection is not passed through, control indication LED lamp by control device 200 and provide alarm signal prompting user, export control signal simultaneously and make eyepiece device 300 be in the darkest state.
In addition, can also be arranged sensitivity, shade number and the dark-state delay time on state of by button.
Control device 200 comprises data acquisition unit, self-test unit, data operation processing unit, drive singal output unit and button judging unit.
Data acquisition unit mainly completes the initialization of function, and data timing such as to read at the function.In order to ensure the response speed of protective eye lens, every 0.2ms reads in the voltage signal once produced by light sensitive diode.
Self-test unit mainly completes the light emitting control to Flash cell, and judges the signal obtained by data acquisition unit and calculate, thus provides welding goggles information whether working properly.
Data operation processing unit mainly completes and processes the current duty of rear judgement to the signal collected.In program prevent erroneous judgement and to external world light on the impact of signal having been done suitable process, ensure that the good conformity of eyepiece device from bright speed of changing to blackout and the conversion human eye from dark to bright.
Drive singal output unit mainly exports corresponding pwm signal according to the result of date processing and current ambient temperature, makes eyepiece device be in correct shading status.
Button judging unit mainly regulates parameter when using according to the result of sub key.
It should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
