Description

一种自动遮光电焊镜片 技术领域 本实用新型涉及一种自动遮光电焊镜片，具体是指一种可在光线 较暗的环境下工作的自动遮光电焊镜片。 背景技术 自动遮光电焊镜片可以根据电焊光来控制遮光度， 彻底根除了电 焊职业病一电光性眼炎的发生， 电焊工可以使用双手作业， 减少了焊 接辅助工序， 提高了焊接质量和效率， 减少了焊机的空载耗电， 由此 可见它必将成为更新换代的电悍劳动防护用品。但是由于自动遮光电 悍镜片中采用了防红外线和防紫外线的滤光片及两片液晶片，没有电 焊弧光照射时， 透光率较低， 在室内光线不足的情况下或在机器设备 背光等情况下电焊工往往看不清焊接点，这样容易造成焊接质量不良 的情况。 发明内容 本实用新型针对现有技术存在的问题，提供一种保证暗态环境下 焊接质量良好， 使用方便的自动遮光电焊镜片。 本实用新型所采用的技术方案为：
一种自动遮光电焊镜片， 包括视窗和边框， 视窗依次由滤光片、 液晶片叠置而成，所述的自动遮光电焊镜片带有照明装置， 照明装置 包括电连接成一个回路的发光体、 开关和电源， 所述发光体设于边框 上朝向悍接物的面。
所述发光体采用发光二极管。
所述开关为延时开关。
所述延时开关包括按钮、 用于充放电的电容器、 放电电阻、 门电 路芯片及三极管。 按钮一端与电源端相连， 另一端与电容器相连， 电 容器与放电电阻并联， 门电路芯片输入端与电容器电压输出端相连， 门电路芯片输出端与三极管基极相连， 三极管发射极接地， 发光二极 管阴极与三极管集电极相连， 发光二极管阳极接电源端。
所述门电路芯片采用 74HC14芯片。
所述门电路芯片包括 6个非门， 非门 A、 非门 B、 并联后的非门 C和非门 F、 并联后的非门 D和非门 E依次串联， 非门 A的输入端作 为门电路芯片的输入端，非门 D和非门 E的输出端并联后作为门电路 芯片的输出端。
放电电阻采用并联的两个电阻。
电源端并联有去耦电容。
本实用新型的有益效果在于： 1 ) 由于带有照明装置， 便于在暗 态工作环境下找准焊接位置， 保证焊接质量； 2 ) 采用延时开关， 节 省电能， 省去关闭发光体的操作， 使用更方便； 3 )采用 CMOS门电路 芯片， 功耗低， 输入阻抗高， 因此充放电电路中的电容器容量可以较 小， 节省成本， 减轻重量； 5 ) 采用两个电阻并联作为放电电阻， 便 于调整放电时间。 附图说明
图 1为本实用新型结构示意图；
图 2为延时开关电路图；
图 3为门电路芯片的内部结构示意图；
图 4为芯片内门电路连接示意图。
具体实施方式
以下结合实施例和附图对本实用新型作进一步说明：
参见图 1， 一种自动遮光电焊镜片， 包括视窗 1和边框 2， 视窗 1依次由滤光片、液晶片叠置而成，边框 2内布有电连接的控制芯片、 光电传感器、 太阳能电池， 本实用新型是对现有技术的改进， 其改进 之处在于： 还设有照明装置， 照明装置包括电连接成一个回路的发光 体 3、 开关 4和电源 5， 发光体 3设于边框 2上朝向焊接物的面。 本 实施例中， 电源 4采用锂电池， 发光体采用发光二极管， 开关采用延 时开关， 发光二极管可以在每次点亮一段时间后自动熄灭。
参见图 2， 延时开关包括： 按钮 Sl、 用于充放电的电容器 El、 放电电阻^ 门电路芯片 IC1及三极管 D1 ; 本实施例中， 门电路芯片 采用 74HC14, 其内部结构如图 3所示， 包括 6个集成封装的非门， 使用时连接关系如图 4所示， 非门 A、 非门 B、 并联后的非门 C和非 门F、 并联后的非门 D和非门 E依次串联， 非门 A的输入端作为门电 路芯片的输入端，非门 D和非门 E的输出端并联后作为门电路芯片的 输出端， 门电路芯片 74HC14本身耗电量低， 输入阻抗高， 采用容量 较小的电容器即可保证足够长的放电时间，也进一步减轻了电焊镜片 的重量， 当然也可以采用 555芯片或者其他门电路。
按钮 S1—端与电源端 Vcc相连， 另一端与电容器 E1相连， 电容 器 E1与放电电阻 R并联，门电路芯片 IC1输入端与电容器 E1电压输 出端相连，门电路芯片 IC1输出端通过限流电阻 R3与三极管 D1基极 相连， 三极管 D1发射极接地， 发光二极管 LED阴极与三极管 D1集电 极相连， 发光二极管 LED阳极接电源端 Vcc。 电源端 Vcc并联有去耦 电容 E2， 放电电阻 R采用并联的两个电阻 R1和 R2， 为了使照明装置 体积尽量小， 采用可调电阻是不现实的， 使用两个并联的电阻可很方 便地选择放电电阻阻值以设定放电时间。当需要启动照明装置时， 按 下按钮 Sl， 电源端 Vcc向电容器 El充电， 门电路输出高电位， 通过 三极管 D1进行电流放大使发光二极管发光。同时电容器 E 1通过电阻 Rl、 R2放电， 当电容器 E1两端的电压低于门电路的导通阈值时， 门 电路输出为零， 三极管 D1截止， 发光二极管停止发光， 从而完成了 一个照明的周期。 采用定时设计一方面是为了节约用电， 另一方面， 因为整个面罩是要戴在头上工作的， 因此面罩的重量越轻越好， 电池 体积应尽量小， 重量尽可能轻。
