Quartz and Graphite Boat Position Detection with Laser Displacement Sensor

Industry pain points and demands

In photovoltaic production, quartz and graphite boats are vital for the diffusion and oxidation of silicon wafers in high-temperature furnaces. After completing these processes, the quartz boats exit the furnace carrying delicate silicon wafers. Accurate position detection is critical to ensure robotic arms can securely and efficiently handle these boats.

SinceVision’s SD-C400 Laser Displacement Sensors deliver precise detection of quartz and graphite boat positions. These sensors excel even on challenging frosted or translucent quartz surfaces and can operate reliably at temperatures up to 85°C. With positioning accuracy of up to 0.5 mm, they ensure seamless operation in high-demand production environments.
