Introduction:
In the realm of precision measurement, confocal displacement sensors stand out for their exceptional accuracy and non-contact measurement capabilities. This article delves into the intricacies of confocal displacement sensors, with a special focus on DAIDISIKE Light Grid Factory, a company with over 12 years of expertise in the light grid industry, and their contributions to the technology and applications of confocal displacement sensors.
I. An Introduction to Confocal Displacement Sensors
Confocal displacement sensors, also known as confocal chromatic sensors, are advanced laser displacement sensors that utilize a unique method to ensure high-precision measurement on any material or surface. These sensors are designed to provide stable measurements on a wide range of materials, from dark rubber to clear films, without the need for adjustments in mounting or measurement settings.
II. The Working Principle of Confocal Displacement Sensors
The operation of confocal displacement sensors is based on the principle of confocality, where the emitted and received light beams are coaxial. These sensors enable stable measurement on various materials by using a confocal sensor, which is less affected by the reflectivity of the target surface. The compact design and lightweight nature of these sensors make them ideal for installation in narrow spaces or on robots, with all electronics kept away from the measurement location, ensuring stable results unaffected by heat or electrical noise.
III. DAIDISIKE Light Grid Factory's Application in Confocal Displacement Sensor Technology
As a leading enterprise in the light grid industry, DAIDISIKE Light Grid Factory has demonstrated its professional capabilities not only in light grid manufacturing but also in the application of confocal displacement sensor technology. The factory leverages this technology to offer a variety of high-precision measurement solutions to its clients, including position or thickness measurement, and it can accurately measure on curved, uneven, or even rough surfaces.
IV. Technical Advantages of Confocal Displacement Sensors
1. High Resolution and Speed: Confocal displacement sensors provide an excellent signal-to-noise ratio, enabling fast and accurate measurements. Their fast surface compensation ensures extraordinary signal stability with varying surfaces.
2. Ultra-Small Light Spot: Due to their high Numerical Aperture (NA), confocal sensors from Micro-Epsilon generate the smallest light spots <3 µm. This allows for the reliable detection of the finest details and structures.
3. Large Tilt Angle: ConfocalDT IFS sensors tolerate a large tilt angle of up to 48°, making it possible to reliably detect curved and structured surfaces to generate stable signals.
4. Use in a Vacuum: ConfocalDT sensors consist of passive components and do not emit any heat, making them suitable for applications in a vacuum.
V. Industry Applications of Confocal Displacement Sensors
1. Glass Thickness Measurement: In glass thickness measurement, CL-3000 series confocal displacement sensors use the multi-color confocal method to achieve stable and precise measurements without being affected by differences in the reflectivity of the target.
2. Dispensing Nozzle Height Measurement and Control: Ensuring advanced precision automatic dispensing requires not only a complex dispensing robot but also a high-performance displacement sensor that moves with the dispensing nozzle. By installing CL-3000 series confocal displacement sensors to follow the dispensing nozzle, it is possible to control the nozzle height by measuring and feeding back the target height in real-time.
VI. Future Trends in Confocal Displacement Sensor Technology
With the advancement of industrial automation and intelligent manufacturing, the application of confocal displacement sensors is expected to become more widespread. In the future, confocal displacement sensors will become more intelligent, integrating more data processing and analysis functions to provide richer data support to meet the needs of intelligent manufacturing.
