Double Sheet Detection of Solar Wafers in Photovoltaic Chip Production Using Ultrasonic Sensors

Double Sheet Detection of Solar Wafers in Photovoltaic Chip Production Using Ultrasonic Sensors

Summary

The CSDA Series Double Sheet Sensor is designed for precise detection of single and double sheets in various materials such as paper, film, silicon wafers, and more. With a small blind zone (5-7 mm), multiple output options (NPN/PNP), and auto-learning capability, it ensures reliable performance in automated production processes within a wide voltage range (DC 10-30V). Ideal for the photovoltaic, electronics, and packaging industries.

Solution

In photovoltaic chip production, solar wafers are both thin and relatively light, making them prone to sliding during the cleaning process. To prevent the breakage or damage of other wafers during subsequent processes (such as handling), stacked wafers must be quickly detected.

The CSDA Series Ultrasonic Double Sheet Sensor can distinguish between single sheets, double sheets, and air, and easily recognize various materials such as paper, films, silicon wafers, adhesive tapes, lithium battery sheets, and PCBs, thereby promptly reporting any errors in positioning to ensure a smooth production process.
