Color Sensing Technology for Production Line Optimization: Equipment Part Color Detection and Identification

1. Company Introduction

Located in Chengdu, a high-tech enterprise focuses on urban rail transit products and system integration. The customer provides advanced technical solutions to improve production efficiency and product quality. In pursuit of innovation and excellence, the customer adopted the Atonm Color Sensor CL2 to solve equipment part color identification.

2. Project Requirements

The customer needed to identify the color of passing boxes and send the recognition results to a PLC system for further processing. Boxes come in four distinct colors; accurate and fast color detection is critical to their production process.

 3. Solution

To meet the customer requirement, we recommended the Atonm Color Sensor CL2. The sensor offers the following features:

1. Flexible parameter settings: Atonm Color Sensor CL2 allows users to preset up to 8 colors and recognize 4 colors simultaneously. This flexibility enables customization for various application scenarios to meet equipment part color recognition needs.

2. High-speed response: The sensor provides a 200μs response time and, together with various dedicated color probes, can accommodate different sizes and distances. This enables rapid and accurate color recognition on the production line without causing delays.

3. Accurate color recognition: Atonm Color Sensor CL2 uses triple 16-bit RGB light sources to precisely detect subtle color differences of about 2–3 degrees, allowing reliable differentiation even for similar colors.

4. Support for complex scenarios: The sensor supports switching between color mode and light-intensity mode; using RGB comparison and brightness contrast, it handles challenging lighting and subtle color changes while maintaining accuracy.

 4. Customer Benefits

1. Improved production efficiency: Fast response and accurate color recognition enable automation. Compared with manual inspection, which consumes time and is prone to errors, the sensor allows boxes to be identified quickly and accurately, saving time and labor and significantly improving production efficiency.

2. Reduced error rate: Manual color inspection is affected by fatigue and vision, increasing error rates. The high-precision recognition of the color sensor eliminates such human errors, reducing defects and after-sales issues and lowering production costs.

3. Flexible adaptation to diverse needs: Atonm Color Sensor CL2 provides flexible parameter settings that allow presetting and recognition of multiple colors. This ensures accurate detection across different environments and products, adapting to varied requirements.

5. Conclusion

By using the Atonm Color Sensor CL2 solution, the customer achieved significant benefits in identifying equipment part colors: improved production efficiency and product quality, reduced error rates and defects, and flexible parameter settings to meet diverse needs. As a technology-driven company, we will continue to provide advanced solutions to help customers succeed in competitive markets.
