Application Cases of Integrated Servo Motors in Image Measurement Platforms
In the field of precision measurement, image measurement platforms require extremely high positioning accuracy and stability from their motion systems. Using an integrated servo motor (PMM2820B) as the core drive component of this image measurement platform, high-precision measurement was successfully achieved through the coordinated operation of contour position mode, contour speed mode, and origin return mode. During debugging, the jitter issue that occurred during motor movement was addressed by checking and readjusting the installation accuracy, ensuring stable operation of the equipment and providing a reliable guarantee for subsequent high-precision image measurements.
1. Equipment Introduction
An image measurement platform is a device used for high-precision optical measurement, widely applied in electronics, machinery, mold making, scientific research, and other fields. It captures images of the object being measured using a high-resolution camera and uses software to perform precise measurements of dimensions, angles, and geometry. The core components of this equipment include an optical system, a motion system, and a control system, with the performance of the motion system directly determining the measurement accuracy and repeatability.
2. Application Scheme
The integrated servo motor PMM2820B-485-0FS is mainly used to drive the X-Y axis motion system in the image measurement platform. Its contour position mode achieves high-precision point-to-point positioning, contour speed mode ensures smooth speed transitions during movement, and origin return mode guarantees consistent reference position after each power-on or reset, thus greatly improving the measurement accuracy and repeatability of the equipment.
3. Application Product
The product used in this case is the PMM2820B-485-0FS integrated servo motor. This motor integrates the driver, controller, and encoder, supports multiple communication protocols and advanced motion control functions, and features small size, simple wiring, and high control precision, making it ideal for image measurement equipment with limited space and high precision requirements.
4. Problems and Solutions
During the commissioning process, the customer reported a vibration phenomenon during motor movement. Inspection revealed that the problem stemmed from insufficient precision of the mounting screw. By loosening the fixing screw and then slowly and evenly tightening it again, the fit between the screw and the motor was optimized, ultimately eliminating the vibration problem and ensuring smooth motor movement and measurement accuracy.
5. Summary and Conclusion
This case demonstrates the successful application of an integrated servo motor in an image measurement platform. By selecting appropriate components and optimizing the installation process, the vibration problem during equipment operation was effectively solved, ensuring the high precision and stable operation of the image measurement platform. This solution provides a valuable reference for the design and commissioning of motion control systems for similar precision measuring equipment.
