中空玻璃生产线光电开关小难题：感应不到磨砂玻璃？这样调就管用

　　Small problem with photoelectric switch in insulated glass production line: unable to sense frosted glass? This adjustment works

　　在中空玻璃生产线中，光电开关就像“眼睛”一样，负责精准检测玻璃的位置，保障送料、合片、打胶等环节的有序衔接。但不少一线师傅都遇到过一个棘手问题：光电开关对磨砂玻璃感应不灵敏，甚至完全没反应，直接导致设备停摆、生产卡顿。其实这不是设备故障，只要掌握正确的接线规范和调节方法，就能轻松解决。今天就专门科普中空玻璃生产线光电开关的实用知识，重点说说感应磨砂玻璃的调试技巧。

　　In the production line of insulating glass, the photoelectric switch is like an "eye", responsible for accurately detecting the position of the glass, ensuring the orderly connection of feeding, laminating, gluing and other links. But many frontline workers have encountered a tricky problem: the photoelectric switch is not sensitive to frosted glass, and even has no response at all, directly leading to equipment shutdown and production lag. Actually, this is not a device malfunction. As long as you master the correct wiring specifications and adjustment methods, it can be easily solved. Today, we will specifically popularize the practical knowledge of photoelectric switches in insulated glass production lines, with a focus on the debugging techniques of induction frosted glass.

　　先跟大家理清基础：咱们中空线上用的光电开关，常规接三根线就够用，接线是否规范直接影响感应效果，这是调试的前提。具体接线规则很明确：棕色线是正极，要对应接到信号电箱里的24V接口；蓝色线是负极，对应信号电箱的0V接口；黑色线是信号线，连接到电箱内标注“X某某某”的对应接口。实操中建议先确认接线无误，很多时候感应失灵不是调节问题，而是接线接错或松动导致的。

　　First, let me clarify the basics for everyone: the photoelectric switch used on our overhead line is usually connected with three wires, and whether the wiring is standardized directly affects the sensing effect, which is a prerequisite for debugging. The specific wiring rules are very clear: the brown wire is the positive pole and should be connected to the 24V interface in the signal box; The blue line is the negative pole, corresponding to the 0V interface of the signal box; The black wire is the signal wire, connected to the corresponding interface labeled 'X' inside the electrical box. In practical operation, it is recommended to first confirm that the wiring is correct. Often, induction failure is not due to adjustment issues, but rather caused by incorrect or loose wiring.

　　解决了接线问题，再来说核心的调节方法——针对感应不到磨砂玻璃的情况，关键就是调节光电开关上的调节按钮。不过要注意，咱们设备的光电开关大多藏在版面内部，平时看不到调节按钮，需要先把光电开关拆下来再操作，拆的时候注意做好部件收纳，避免螺丝丢失。

　　After solving the wiring problem, let's talk about the core adjustment method - for situations where frosted glass cannot be sensed, the key is to adjust the adjustment button on the photoelectric switch. However, it should be noted that the photoelectric switches of our equipment are mostly hidden inside the layout, and the adjustment buttons cannot be seen normally. Therefore, it is necessary to remove the photoelectric switches before operation. When removing them, pay attention to organizing the components properly to avoid losing screws.

　　调节的标准很简单，两步就能确认：第一步，把需要检测的磨砂玻璃放到指定位置，然后慢慢旋转调节按钮；第二步，观察光电开关上的指示灯，当指示灯亮起时，就说明调节到位了。如果想更精准，还可以同步查看设备的触摸屏，确认对应的输入信号是否正常显示——指示灯亮且触摸屏有信号，就代表光电开关已经能稳定感应磨砂玻璃了。

　　The standard for adjustment is very simple, it can be confirmed in two steps: first, place the frosted glass that needs to be tested in the designated position, and then slowly rotate the adjustment button; Step two, observe the indicator light on the photoelectric switch. When the indicator light is on, it means that the adjustment is in place. If you want to be more precise, you can also synchronously check the touch screen of the device to confirm whether the corresponding input signal is displayed normally - if the indicator light is on and there is a signal on the touch screen, it means that the photoelectric switch can stably sense the frosted glass.

　　这里给大家补充几个实操小提醒：一是拆光电开关时要轻拿轻放，避免碰撞损坏内部元件；二是调节按钮时幅度要小，慢慢旋转观察指示灯，不要一次性拧到底，防止调节过度反而影响感应稳定性；三是调节完成后，把光电开关装回原位时要固定牢固，避免设备运行中因振动导致位置偏移，再次出现感应问题。

　　Here are a few practical tips for everyone: First, when dismantling the photoelectric switch, handle it gently to avoid collision and damage to internal components; Secondly, when adjusting the button, the amplitude should be small. Slowly rotate and observe the indicator light, and do not twist it all at once to prevent excessive adjustment from affecting the sensing stability; Thirdly, after the adjustment is completed, the photoelectric switch should be firmly fixed back to its original position to avoid position deviation caused by vibration during equipment operation, which may lead to induction problems again.

　　另外，日常使用中还有两个小技巧能减少感应故障：一是定期检查光电开关的镜头，磨砂玻璃生产过程中容易产生粉尘，镜头沾灰会影响感应，定期用干净的布擦拭干净即可；二是如果经常需要切换检测普通玻璃和磨砂玻璃，建议做好调节参数记录，后续切换时能快速调试到位，节省时间。

　　In addition, there are two tips in daily use to reduce sensing faults: first, regularly check the lens of the photoelectric switch. Dust is easily generated during the production process of frosted glass, and lens dust can affect sensing. Regularly wipe it clean with a clean cloth; Secondly, if it is necessary to frequently switch between detecting ordinary glass and frosted glass, it is recommended to keep a record of the adjustment parameters, so that the subsequent switching can be quickly adjusted to save time.

　　光电开关虽小，却是中空玻璃生产线稳定运行的关键部件，感应不到磨砂玻璃的问题看似棘手，实则只要做好接线规范和精准调节就能解决。对一线操作人员来说，掌握这些基础调试技巧，能快速应对生产中的小卡顿，减少生产线停摆时间。希望这次科普能帮到大家，在日常操作中更好地应对光电开关的各类小问题。如果遇到其他感应故障，也可以先从接线和清洁镜头入手排查，或咨询设备厂家的技术支持。

　　Although the photoelectric switch is small, it is a key component for the stable operation of the insulated glass production line. The problem of not sensing frosted glass may seem tricky, but in fact, it can be solved as long as the wiring specifications and precise adjustments are done properly. For frontline operators, mastering these basic debugging skills can quickly respond to small lags in production and reduce downtime on the production line. I hope this science popularization can help everyone better deal with various small problems of photoelectric switches in daily operation. If you encounter other induction faults, you can also start troubleshooting by wiring and cleaning the lens, or consult the technical support of the equipment manufacturer.
