Description

自动变光滤光镜的光阀色号控制方法 技术领域
本发明涉及焊工用焊接面罩技术领域，尤其涉及自动变光滤光镜的光阀色号控制方法。
背景技术
传统自动变光滤光镜(auto darkning filter以下简称ADF)会根据检测到的焊接弧光信号，按照图1的流程来控制光阀色号的变化过程；其中，横坐标X方向用来表示时间，纵坐标Y方向用来表示光阀色号的数值，通过ADF光阀的黑度/透过率获得：
步骤A01:当ADF处于待机时刻，光阀的当前色号处于亮态，一般处于稳定的3#或者4#，由光阀的物理特性所决定的；
步骤A02:当ADF的控制电路检测到焊接弧光信号之后，控制电路控制ADF进入正常工作时刻，控制电路会控制光阀维持目标色号的数值，该数值由使用者设定；
步骤A03:当焊接弧光信号消失之后，控制电路便会控制光阀回到亮态，ADF回到待机状态，等待下一次焊接弧光信号。
在上述过程中，在色号由高变低即由暗态转为亮态的过程中，转变瞬时发生且变化幅度较大，因此使得使用者的舒适度较低，长时间的工作后，会使得眼部疲劳程度较高。
发明内容
本发明提供了一种自动变光滤光镜的光阀色号控制方法，可有效解决背景技术中的问题。
为了达到上述目的，本发明所采用的技术方案是：
自动变光滤光镜的光阀色号控制方法，包括以下步骤：
将当前的光阀色号控制在第一色号，且持续对焊接弧光信号进行检测，直至检测到所述焊接弧光信号，执行下一步骤；
控制所述光阀的第一色号变化至目标色号，且维持所述目标色号进行焊接工作，直至所述焊接弧光信号中断，执行下一步骤；
控制所述光阀在T 2时间段内从目标色号向第一色号过渡，且过渡过程中至少经过一个中间色号；
所述第一色号小于所述目标色号。
进一步地，所述光阀从目标色号向第一色号过渡过程中，色号变化过程为线性变化过程。
进一步地，所述光阀从目标色号向第一色号过渡过程中，色号变化过程为阶梯状变化过程。
进一步地，检测到所述焊接弧光信号后，还包括以下步骤，使得所述光阀从第一色号变化为目标色号：
向所述光阀施加高压信号，且维持T 0时间段，所述光阀获得第二色号；
控制所述光阀在T 1时间段内从第二色号向目标色号过渡，且过渡过程中至少经过一个中间色号；
其中，所述目标色号介于所述第一色号和第二色号之间，且所述目标信号小于所述光阀的最高色号。
进一步地，所述中间色号至少包括所述光阀的最高色号。
进一步地，所述最高色号维持T 11时间段，所述光阀在T 12时间段内从所述最高色号向目标色号过渡，且色号变化过程为线性变化过程；
其中，T 12＝T 1-T 11。
进一步地，所述最高色号维持T 11时间段，所述光阀在T 12时间段内从所述最高色号向目标色号过渡，且色号变化过程为阶梯状变化过程；
其中，T 12＝T 1-T 11。
进一步地，所述T 12时间段长于所述T 11时间段。
自动变光滤光镜的光阀色号控制方法，包括以下步骤：
将当前的光阀色号控制在第一色号，且持续对焊接弧光信号进行检测，直至检测到所述焊接弧光信号，执行下一步骤；
向所述光阀施加高压信号，且维持T 0时间段，所述光阀获得第二色号；
控制所述光阀在T 1时间段内从第二色号向目标色号过渡，且过渡过程中至少经过一个中间色号；其中，所述目标色号介于所述第一色号和第二色号之间，且所述目标信号小于所述光阀的最高色号；
维持所述目标色号进行焊接工作。
进一步地，所述高压信号为正电压。
进一步地，所述高压信号为负电压。
通过本发明的技术方案，可实现以下技术效果：
传统的自动变光滤光镜在焊接弧光信号消失后，控制电路会将光阀由目标色号立即切换到亮态色号，如果使用者正在进行大电流焊接，那么即使焊接弧光结束之后，被焊接的工件仍然会有炙热的熔池，此时光阀由目标色号切换到亮态瞬时发生，使用者会感觉到刺眼而对视力造成损伤；通过发明中的技术方案视觉的转换可获得延时时间，从而有效的提高了操作者的舒适性。
另外，传统的自动变光滤光镜在向光阀施加完高压之后，控制电路会直接将光阀立即切换到目标色号，此种情况下如果目标色号过低，会给使用者带来视觉上的不适感，因为在极短的时间内，色号的变化值较大，使用者会察觉到由于高压信号的存在先是极暗环境，而后通过色号的转变又立即跳转到比较明亮的状态，用户会误以为被电焊弧光“打眼”；通过本发明使得极暗环境到目标色号之间获得过渡，通过变化的过程使得操作者可明确环境明暗程度的变化并不来自于弧光，且可获得适应明暗 变化的时间，从而获得更好的使用体验。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理 解的含义相同。在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
实施例一
如图2所示，自动变光滤光镜的光阀色号控制方法，包括以下步骤：
S1：将当前的光阀色号控制在第一色号，此时自动变光滤光镜处于待机状态，当前的光阀色号为亮态，一般处于稳定的3#、4#，或者也可采用其他色号数值，如图3和4所示，本实施例中采用3#作为第一色号；且持续对焊接弧光信号进行检测，直至检测到焊接弧光信号，执行步骤S2；
S2：控制光阀的第一色号变化至目标色号，且维持目标色号进行焊接工作，直至焊接弧光信号中断，执行步骤S3；
S3：控制光阀在T 2时间段内从目标色号向第一色号过渡，此时自动变光滤光镜开始延时时刻，准备控制光阀回到亮态，自动变光滤光镜回到待机状态；且过渡过程中至少经过一个中间色号，从而通过渐变的过程保护使用者的眼睛，提高焊接舒适性；其中，第一色号小于目标色号。
步骤S3结束后，重新返回步骤S1,等待下一次焊接弧光信号。其中，延时时间T 2时间段是可以调节的，调节范围从数微秒至数秒，使用者可以根据被焊接工件类型、焊接电流大小、焊接余温高低等情况，来自由设置延时时间T 2。
通过本实施例，有效的解决了以下问题：
传统的自动变光滤光镜在焊接弧光信号消失后，控制电路会将光阀由目标色号立即切换到亮态色号，如果使用者正在进行大电流焊接，那么即使焊接弧光结束之后，被焊接的工件仍然会有炙热的熔池，此时光阀由目标色号切换到亮态瞬时发生，使用者会感觉到刺眼而对视力造成损伤；通过本实施例中的技术方案视觉的转换可获得延时时间，从而有效的提高了操作者的舒适性。
作为本实施例的优选，光阀从目标色号向第一色号过渡过程中，色号变化过程为线性变化过程，如图3所示，从而使得视觉的过渡更加平缓。或者，作为另外一种实施方式，光阀从目标色号向第一色号过渡过程中，色号变化过程为阶梯状变化过程，如图4所示，此种方式中，虽然色号变化的平缓程度较第一种方式差，但是同样存在自身的优势，通过阶梯状过渡形式，使得相邻色号之间的变换存在停顿，此种停顿可使得操作者获得对焊接物品进行判断的短暂时间；当操作者通过短暂的停顿将焊接物的变化和色号的变化进行区分时，可获得对焊接过程更好的控制。
实施例二
如图5所示，自动变光滤光镜的光阀色号控制方法，包括以下步骤：
S1：将当前的光阀色号控制在第一色号，此时自动变光滤光镜处于待机状态，当前的光阀色号为亮态，一般处于稳定的3#、4#，或者也可采用其他色号数值，如图3和4所示，本实施例中采用3# 作为第一色号；且持续对焊接弧光信号进行检测，直至检测到焊接弧光信号，执行下一步骤；
S21：向光阀施加高压信号，且维持T 0时间段，光阀获得第二色号,T 0时间段可调节，调节范围从数微秒至数秒；本步骤中，通过高压信号的施加，使得光阀的启动速度大幅提升，存在高压的情况下，从检测到焊接弧光，到光阀变黑最快只要50微秒，没有高压的情况下，这个时间可能要2毫秒，上述耗时的差异使得使用者的感受大大不同；本步骤中所获得的第二色号会高于光阀的最高色号，最高色号是由控制电路和光阀的物理特性所决定的，如图6～9所示，展示了第二色号为17#的形式；
S22：控制光阀在T 1时间段内从第二色号向目标色号过渡，且过渡过程中至少经过一个中间色号，T 1时间段可调节，调节范围从数微秒至数秒；其中，目标色号介于第一色号和第二色号之间，且目标信号小于光阀的最高色号；同样地，通过渐变的过程保护使用者的眼睛，提高焊接舒适性；
S23：维持目标色号进行焊接工作；
直至焊接弧光信号中断，执行下一步骤；
S3：控制光阀在T 2时间段内从目标色号向第一色号过渡，此时自动变光滤光镜开始延时时刻，准备控制光阀回到亮态，自动变光滤光镜回到待机状态；且过渡过程中至少经过一个中间色号，从而通过渐变的过程保护使用者的眼睛，提高焊接舒适性；其中，第一色号小于目标色号。
步骤S3结束后，重新返回步骤S1,等待下一次焊接弧光信号。本实施例中，延时时间T 2时间段同样是可以调节的，调节范围从数微秒至数秒，使用者可以根据被焊接工件类型、焊接电流大小、焊接余温高低等情况，来自由设置延时时间T 2。
通过本实施例，除了实施例一中所解决的技术问题，还解决了以下问题：
传统的自动变光滤光镜在向光阀施加完高压之后，控制电路会直接将光阀立即切换到目标色号，当然，目标色号的具体色号由用户设定，如图6～9所示，展示了目标色号为9#的方案；此种情况下如果目标色号过低，会给使用者带来视觉上的不适感，因为在极短的时间内，色号的变化值可能已经超过了10个，使用者会察觉到由于高压信号的存在先是极暗环境，而后通过色号的转变又立即跳转到比较明亮的状态，用户会误以为被电焊弧光“打眼”；通过本实施例，使得极暗环境到目标色号之间获得过渡，通过变化的过程使得操作者可明确环境明暗程度的变化并不来自于弧光，且可获得适应明暗变化的时间，从而获得更好的使用体验。
作为本实施例的优选，中间色号至少包括光阀的最高色号，最高色号通常在11#～16#的范围内，如图6所示，展示了中间色号仅仅包括光阀的最高色号，且最高色号持续T 1时间段的情况，通过控制光阀在最高色号，使得高压信号结束后的光阀回到正常工作的情况；其中，T 1时间段可由用户调节，调节范围从数微秒至数秒。
当然，除了中间色号仅仅包括最高色号的情况，从第二色号向目标色号过渡的过程中还可包括其 他中间色号，如图7所示，最高色号维持T 11时间段，光阀在T 12时间段内从最高色号向目标色号过渡，且色号变化过程为线性变化过程，其中，T 12＝T 1-T 11；通过此种方式使得视觉的过渡更加平缓，且通过最高色号与目标色号之间差异的最大化，可使得操作者获得最大的适应空间。
或者，作为另外一种实施方式，如图8所示，最高色号维持T 11时间段，通过持续使得使用者可通过该时间段获得对最高色号的适应过程，也使得光阀获得稳定；光阀在T 12时间段内从最高色号向目标色号过渡，且色号变化过程为阶梯状变化过程，其中，T 12＝T 1-T 11；此种方式中，虽然色号变化的平缓程度较第一种程度差，但同样地通过阶梯状过渡形式，使得相邻色号之间的变换存在停顿，此种停顿可使得操作者获得对弧光进行判断的短暂时间。
在本实施例中，优选T 12时间段长于T 11时间段，从而在操作者和光阀均通过最高色号进行过渡后，可获得更多从最高色号向目标色号进行过渡的时间，从而获得更好的使用体验。
如图7所示，展示了光阀在T 12时间段内从最高色号向目标色号过渡，且色号变化过程为线性变化过程，以及，光阀从目标色号向第一色号过渡过程中，色号变化过程为线性变化过程的实施方式；如图8所示，展示了光阀在T 12时间段内从最高色号向目标色号过渡，且色号变化过程为阶梯状变化过程，以及，光阀从目标色号向第一色号过渡过程中，色号变化过程为线性变化过程的实施方式；除了上述情况外，本发明中还对上述方式中光阀从目标色号向第一色号过渡过程中，色号变化过程为线性变化过程的替代方式进行保护，如图9所示，展示了对图8进行替换的情况。
实施例三
如图10和11所示，自动变光滤光镜的光阀色号控制方法，包括以下步骤：
S1：将当前的光阀色号控制在第一色号，且持续对焊接弧光信号进行检测，直至检测到焊接弧光信号，执行下一步骤；
S21：向光阀施加高压信号，且维持T 0时间段，光阀获得第二色号；
S22：控制光阀在T 1时间段内从第二色号向目标色号过渡，且过渡过程中至少经过一个中间色号；其中，目标色号介于第一色号和第二色号之间，且目标信号小于光阀的最高色号；
S23：维持目标色号进行焊接工作。
本实施例中，步骤S1～S23所起到的技术目的与上述实施例二中相同；而不同的是，上述技术方案可通过与不同的目标色号向第一色号的变化方式组合，从而获得与实施例二不同的技术方案，而所指的技术方案中至少包括如图12所示的方式：当焊接弧光信号消失之后，控制电路便会控制光阀回到亮态，ADF回到待机状态，等待下一次焊接弧光信号的方式；此种方式尤其适用于目标色号与第一色号之间的数值差较小的情况，和/或焊接处熔池面积小的情况，上述情况下快速的色号变化对操作者的使用舒适度影响较小，可降低控制的难度。
作为本实施例的优选，如图13所示，本发明中同样对从最高色号直接向目标色号进行过渡的技术方案进行保护，即最高色号并不存在持续的时间，而此种情况下过渡为线性平滑，或者是阶梯状的均在本发明的保护范围内。
作为上述各实施例的优选，高压信号为正电压或负电压，其施加时间是可调节的，调节范围从数微秒至数秒。
本发明中智能化的自动变光滤光镜所有控制技术可基于内部电路中的单片机(MCU)来实现控制，通过色号分段控制技术大大提高了产品的性能，各时间段的关键参数可以由厂家在出厂时设置，或者可以由使用者通过旋钮、按键、遥控器、手机APP、电脑软件等形式进行重新设置，均在本发明的保护范围内。
以上显示和描述了本发明的基本原理、主要特征及优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
