Q：What is the working principle of an automatic alignment correction device?
A：
The working principle of misalignment correction in a light curtain is as follows: The optical protection device detects the misalignment position, and if there is any deviation, it sends out a signal. The optical misalignment software system then performs editing and calculation operations on the signal and sends out control signals. The external actuator is driven by the control system to make corrections in the movement of the material, thus controlling the material to move in a straight line.
The Daide Schex QL series misalignment correction light curtain is suitable for use on various roll-to-roll equipment, such as paper rolls, films, fabrics, non-woven fabrics, and metal foils. It can perform both single-side and double-side misalignment correction. It features a simple wiring installation method and diverse output functions.
The main features of the Daide Schex QL series misalignment correction light curtain are as follows:
1. It can be widely used in industries such as printing and packaging, papermaking, film, and that require control of edge alignment.
2. The QL series misalignment light curtain has a sturdy structure and can perform single-side, double-side, and center alignment correction. The wiring and installation methods are diverse, making it easy to operate.
3. It can detect over long distances and is easy to align, with a maximum detection accuracy of 1.25mm.
4. It offers multiple scanning modes, including parallel scanning and cross scanning.
5. It has RS485 or RS232 communication capabilities, allowing communication with a host computer using the standard MODBUS protocol.
6. The detection distance can reach up to 20,000mm, with a typical protection height ranging from 30-2000mm. The light beam spacing options include 1.25mm, 2.5mm, 5mm, and 10mm, making it suitable for high-precision detection and measurement.
