As industrial automation advances, the demand for precision measurement and control grows, especially in applications requiring exact Z-axis positioning. Dispensing machines, a key component in automated production lines, rely on this accuracy to ensure effective and consistent material application. The HZ Series laser displacement sensors, with high accuracy, repeatability, and non-contact measurement, provide an ideal solution for height measurement in dispensing systems.
Real-Time Feedback on Dispensing Height
In dispensing machines, precise height measurement is essential for controlling material application. The HZ Series laser displacement sensor is mounted on the nozzle lift mechanism, feeding real-time height data for optimal control. Typically, a dispensing machine uses a 2D camera for X-Y positioning and a laser sensor for Z-axis height adjustment, connected through standard serial interfaces such as RS485 or RS422, compatible with most industrial PCs.
Robust Performance in Challenging Environments
Mounted directly on the dispensing head, laser sensors face high-frequency vibration during operation, demanding extreme durability. The HZ Series sensors address this with an 8-million-cycle drag chain cable and UV-bonded optical components, enhancing vibration resistance and ensuring long-lasting performance in harsh settings. This durability is essential for maintaining consistent operation under high-stress conditions.
Advantages of Laser Displacement Sensors
- High Precision: Non-contact laser measurement enables micron-level precision, surpassing traditional methods.
- Fast Response: With a 2KHz sampling rate, sensors detect and respond to micro-variations on PCBA surfaces in real time.
- Versatile Adaptability: The sensors adjust to color variations and different materials across PCBA regions, ensuring reliable dispensing accuracy.
Conclusion
With the increasing need for precision in automated production, the HZ Series laser displacement sensors stand out as a solution, offering high accuracy, durability, and adaptability. As automation continues to evolve, such advanced sensors remain integral to achieving consistent, high-quality results in complex industrial applications.
