Precision Assurance: Laser Tracker Enhances Robot Product Performance

At Robotphoenix, we are committed to providing high-precision, highly reliable industrial robotic solutions. We understand that the performance of robots on the production line directly impacts production efficiency and product quality. Therefore, we employ precise testing instruments and conduct rigorous precision testing and calibration before each robot is shipped to our customers, ensuring that every robot performs optimally in real-world applications.

The Core Role of the Laser Tracker

To ensure the precision of robots, we are equipped with industry-leading laser trackers for precise testing and calibration. As a high-accuracy measurement tool, the laser tracker uses laser beams to track reflective targets and measure the robot’s position and angles in real time. With this technology, we can accurately calibrate multiple parameters of the robot and correct any errors generated during the part processing and assembly stages, thereby improving the robot’s absolute accuracy.

How Precision Calibration and Error Correction Work

Taking the SCARA robot Python450-B6 as an example, the ideal arm lengths for this robot are typically 200mm for the upper arm and 250mm for the lower arm. However, due to slight errors in the part processing and assembly processes, the actual arm lengths may deviate. For instance, the actual upper arm length may be 199.87mm, and the actual lower arm length may be 250.05mm. While these errors are small, even minor deviations can affect the robot’s overall performance in precision industrial applications.

In such cases, the laser tracker allows us to precisely detect these errors and calibrate the robot accordingly. By using the laser tracker’s precise measurements, we can adjust key parameters such as arm lengths, gear reduction ratios, and zero-point positions, ensuring that the robot’s motion accuracy meets design specifications and eliminating any deviations caused by assembly or processing errors.

Detailed Performance Testing and Quantitative Analysis

The laser tracker not only calibrates multiple robot parameters but also tests and analyzes several key performance indicators, including:

• Positioning Characteristics: Accurately measuring the robot’s position errors during operation to ensure it reaches its target positions with precision.

• Trajectory Characteristics: Analyzing the robot’s movement along its programmed path to ensure smooth and consistent motion.

• Minimum Positioning Time: Measuring the time it takes for the robot to start moving from a static position and reach steady state, helping optimize production efficiency.

These tests provide extensive performance data, forming the basis for qualitative and quantitative analysis of the robot system. This data helps us gain a comprehensive understanding of the robot’s operational performance, ensuring it operates stably and efficiently in the customer's production environment.

Creating Greater Value for Customers

Through precise laser tracker testing and calibration, we ensure that every robot is equipped with exceptional accuracy and reliability. This process not only improves the robot’s operational precision but also helps eliminate potential errors and deviations during production, providing our customers with more stable and precise automation solutions.

Additionally, the precise calibration and adjustment process reduces maintenance costs, increases the robot’s long-term reliability, and extends the equipment’s lifespan. Whether it’s part processing, precision assembly, or large-scale automation production, our robotic systems help customers enhance production efficiency, reduce costs, and ensure product quality while strengthening their competitive edge.
