Screen Plate Height Detection with SD22-35 Laser Displacement Sensor | SinceVision

Precision and reliability are the backbone of modern photovoltaic manufacturing. Our Europe Sales Director, Kevin Cheng, demonstrated how the SD22-35 Laser Displacement Sensor delivers real-time and highly accurate screen plate height detection for printing machines.

This application is vital for ensuring screen plates maintain consistent height and alignment during the photovoltaic printing process. Even slight variations can compromise product quality, efficiency, and long-term performance. The SD22-35 is engineered to eliminate such risks with unmatched accuracy and stability.

Why Screen Plate Height Detection Matters in Photovoltaics?

In photovoltaic cell production, screen printing is widely used for applying conductive pastes and coatings. The height of the screen plate directly affects printing thickness, precision, and overall efficiency. Without accurate monitoring, manufacturers face:

a. Defects and rejects from uneven coatings.

b. Reduced efficiency in solar cells due to inconsistency.

c. Higher production costs from wasted materials and rework.

This is why integrating advanced laser displacement sensors is essential for modern PV production lines.

SD22-35 Laser Displacement Sensor: Technical Highlights

The SinceVision SD22-35 Laser Displacement Sensor delivers the speed, precision, and stability essential for photovoltaic applications. With a reference distance of 35mm and a measurement range of ±15mm. It provides accurate detection across varied conditions. The sensor achieves a repeatability of just 6μm, supported by a compact spot size of 100 × 580μm for fine detail measurement. Its selectable sampling frequency: ranging from 300 to 3000Hz, This ensures flexibility for different production line speeds, while the 1mW laser output power offers safe yet reliable performance for continuous industrial use.

These specifications allow manufacturers to detect minute changes in height in real time, ensuring consistent screen printing results and improved process control.
