In the era of 5G,it requires faster signal transmission speed,which is 1~100 times faster than 4G. Commonly. It takes a spectrum over 3Ghz for 5G communication with shorter millimeter waves. In production of 5G products, materials with less interference on the signal are of great importance. Compared with metal rear panel, ceramic one is more popular with phone makers, for its non-inference for signals,and superior performance.
Gradually, as industries is getting closer to online,real-time and intelligent development,one phone rear panel manufacturer plans to upgrade his production line with automatic equipment. The reason is because there are many human-caused losses due to crash and counting errors in production. To ensure the normal manufacturing process, this company plans to upgrade its production line with sensors for counting and positioning of products.
However,it will be very hard to detect ceramic rear panel accurately if we just use normal photoelectric sensors. On account of high reflection, ceramic surface will largely weaken the light source from the sensors, leading to lower accuracy. Now let us tell you how we can effectively cope with this problem.
1. Highly reflective objects with ceramic surfaces
2. With curvature
3. Sensing distance:260mm
