Steady! ESB-BY30 series blue light sensor for detecting solar silicon wafers
In the practical application of silicon wafer production in the photovoltaic industry, equipment manufacturers inevitably face the challenge that the special nature of photovoltaic cells makes it difficult for ordinary sensors to stably detect.hotovoltaic, as a clean and renewable energy source, occupies an important position in the future energy structure. With the expansion of investment scale in the photovoltaic industry, the pace of technological innovation is also accelerating, and the automation rate of production lines is rapidly increasing. Therefore, in the practical application of silicon wafer production in the photovoltaic industry, equipment manufacturers inevitably face the challenge that the special nature of photovoltaic wafers makes it difficult for ordinary sensors to stably detect them
Now, Akusense Sensing's new blue light photoelectric sensor ESB-BY30 has solved these problems!
In this issue, Xiao Ming will share the application of Meiji's new blue light photoelectric sensor in the production of photovoltaic silicon wafers~
Scenario requirements
From the upstream to the midstream of the photovoltaic industry, the detection of whether the silicon wafer is in place/present is very important in various silicon wafer automation equipment; A stable and efficient sensor needs to be selected for detection.
▲ Solution
Analysis of Testing Points
1. The essence of silicon wafers is high brightness surfaces and highly reflective objects. Traditional red light sensors cannot measure enough reflected light, making them difficult to detect;
2. After chemical treatment (such as cleaning, diffusion, etching, etc.), the reflectivity of silicon wafers will undergo significant changes
Recommended Selection
ESB-BY30N
Blue light photoelectric sensor
1. Select Meiji blue diffuse reflectance photoelectric sensor ESB-BY30N, 465nm wavelength modulated blue light, short wavelength, high energy, clear and visible blue light spot
2. Due to the higher reflectivity of solar cells in the blue range, the shorter wavelength of blue light can resist absorption. The blue light source provides reflection ability, increasing the amount of light returned to the sensor, thereby achieving stable detection.
3. The Meiji blue light photoelectric sensor ESB-BY30N has excellent background suppression function and is not affected by the reflectivity of the silicon wafer during the detection process, ensuring the reliability of silicon wafer detection.
4. Built in 6-turn potentiometer for fine sensitivity adjustment, everything is under control
5. Three circuit protection mechanisms (power reverse polarity protection, surge protection, short circuit protection) effectively protect sensors
6. Response time of 1.5ms, easily adaptable to the fast-paced production rhythm
