[0014] [0014]

具体实施方式: 为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体图示,进一步阐述本发明。 DETAILED DESCRIPTION: In order to achieve the technical means of the present invention, the creation of features, to achieve the purpose and effect readily apparent appreciated that specifically illustrated below with reference to further illustrate the invention.

[0015] 如图1所示,本发明所述的自动变光焊接面罩中护目镜组结构,其结构包括外保护片101、滤光片102、液晶屏片103 (也称液晶光阀片)和内保护片104 ;所述外保护片101 与内保护片104之间置有一滤光片102和两片液晶屏片103。 [0015] As shown, auto-darkening welding helmet visor according to the present invention in a group structure, which structure comprises an outer protective sheet 101, a filter 102, the liquid crystal panel sheet 103 (also referred to as liquid crystal light valves) and the protective sheet 104; set a filter 102 and two liquid crystal panel 103 between the outer sheet 101 and the protective sheet protective sheet 104.

[0016] 需要指出的是,由于单片液晶屏片在工作过程中不能够取得更高的色号,即不能够阻挡强烈的电弧光,光线透过液晶屏片较多,致使亮度仍然很高,一般人的肉眼难以接受,故本专利这里采用两片液晶屏片可以阻挡更多光线透过,可以将亮度降低到人眼舒适的程度。 [0016] It should be noted that, due to the liquid crystal panel monolithic sheet can not achieve higher color resolution during operation, i.e., can not block the strong arc light, more light through the liquid crystal panel substrate, resulting in high brightness remains , the human eye is generally unacceptable, so the patent herein using two LCD may block more light through the sheet, the brightness can be reduced to a comfortable level of the human eye.

[0017] 此外,这里采用的两片液晶屏片都连接镜片控制电路,通过接收控制电路信号来实现在0. 1毫秒内明态到暗态转换,并还可以实现0. 1毫秒到1毫秒内从暗态到明态转换。 [0017] Further, two sheets LCD lenses used here are connected to a control circuit, is achieved within 0.1 millisecond bright state to a dark state signal converted by the reception control circuit, and may also be implemented 0.1 ms to 1 ms from the dark state to the bright state conversion. 具体解释如下: 首先,液晶是在某个温度范围内兼有液态和晶体两种特性的物质状态,具有规则性分子排列的有机化合物,常用的液晶为向列相液晶,分子形状为细长棒形,长度约1〜lOrirn, 在不同的电流作用下,液晶分子会做规则旋转90度排列,产生透过度的差别,因而在电源接通与断开时产生明暗的区别。 Specifically explained as follows: First, both the liquid crystal is within a certain temperature range the liquid state of a substance both characteristics and crystals having a regular molecular arrangement of an organic compound commonly used as nematic liquid crystal, molecular shape of an elongated rod having a length of about 1~lOrirn, at different current is applied, the liquid crystal molecules will make regular arrangement rotated 90 degrees to produce a difference of permeability, thus turning on the power difference generating shading disconnected.

[0018] 当光接收管接受弧光信号到镜组变为暗态时,所需要的时间间隔,称之为响应时间。 [0018] When the light receiving signal to the arc tube receiving lens group becomes dark state, the time interval required, is called response time. 它关系到焊工引弧时受到的强可见光瞬间照射的时间,也关系到电焊工人在焊接过程中能否始终清楚地进行观察,能否彻底地消除盲目引焊而伤害眼睛。 Strong visible light irradiation time instant when it is subjected to the relationship arc welder, but also to the welders can always be clearly observed in the welding process, can completely eliminate blind lead solder and eye damage. 响应时间越短,说明电焊面罩的镜组结构性能越优良。 The shorter the response time, the more excellent structural properties of the welding mask lens group. 镜组的响应时间主要由液晶材料的响应时间和电路中接受弧光的反映速度两部分组成,但液晶光阀片的响应时间是起主要作用的,即液晶屏片的转换时间越小,镜组的响应时间也将大大缩短。 Response time is mainly received by the lens assembly and the response time of the circuit of the liquid crystal material reflects the speed of the arc of two parts, but the response time of the liquid crystal light valve that play a major role, the smaller the transition time of the LCD sheet, mirror group the response time will be greatly reduced.

[0019] 液晶屏片的响应时间与加在其二端的电压大小成正比关系(在一定的范围内),电压越高,响应时间就越短。 [0019] The response time of the liquid crystal panel voltage is proportional to the sheet size and the other end (in a certain range), the higher the voltage, the shorter the response time. 当在护目镜组的液晶屏两端瞬间施加输出与占空比成比例的直流高压,在常温的条件下,在DIN13时,其响应时间能达到0. lms。 When applied to the output duty cycle proportional to the DC high voltage at the moment of the liquid crystal panel ends goggles group, at normal temperature, when DIN13, response time can be achieved 0. lms.

[0020] 其次,滤光片采用真空镀膜技术的带通滤光片。 [0020] Next, the filter band-pass filter using vacuum coating techniques. 滤光片光谱特性主峰在520nm至580nm之间,峰值透射率大于50%。 Filter characteristic spectral peak between 520nm to 580nm, the peak transmittance of greater than 50%.

[0021] 如表1所示,该表为根据相关标准订立的劳动防护用品质量监督检验站报告,里面记载着红外线、远紫外线、近紫外线、蓝光等有害光线透过率。 [0021] As shown in Table 1, the table according to labor protection articles Quality Supervision and Inspection Station reporting standards made, which records the infrared rays, far ultraviolet rays, near ultraviolet light, blue light and other harmful light transmittance.
