What are the common sensor failures and their solutions for motor motor automatic rotor fine turning vision machine?
Motor motor automatic rotor fine turning vision machine common sensor failure and its solutions are as follows:
First, the visual sensor failure
1, the image is blurred or unclear
Reason analysis: the lens has stains, dust or damage; camera parameters are not set reasonably, such as aperture, focal length, exposure time, etc.; light source intensity is insufficient or uneven.
Solution: use special cleaning tools to clean the lens, such as wiping cloth, cleaning fluid, etc., if the lens is damaged, then replace the lens; re-adjust the camera parameters, through multiple tests to find the best settings; check the light source system, replace the damaged light source components, adjust the position and angle of the light source, to ensure that the light is uniform.
2、Can not recognize the target object
Reason analysis: mismatch of vision algorithm, insufficient recognition ability of current object features; reflections on the surface of the target object, color changes or blocking; changes in the relative position between the camera and the object.
Solution: Optimize the vision algorithm to increase the accuracy of feature extraction and matching, or replace a more suitable algorithm model; pre-process the target object, such as removing reflections, uniform color, etc., and clean up the obstruction; recalibrate the relative position between the camera and the object to ensure stable imaging.
3、Decrease in detection accuracy
Reason analysis: camera resolution is insufficient; vision system is subject to external electromagnetic interference; loose mounting bracket leads to camera shake.
Solution: Consider replacing the camera with a higher resolution; electromagnetic shielding of the vision system, check the grounding of electrical equipment to reduce the source of interference; tighten the camera mounting bracket, if necessary, increase the vibration damping measures.
Second, the position sensor failure
1, signal loss or instability
Reason analysis: sensor connection line loose, broken or short-circuit; the sensor itself is damaged; around a strong magnetic field interference.
Solution: check the connection line, re-plugging or welding loose joints, repair broken or short-circuit; replace the damaged position sensor; sensor magnetic shielding treatment, away from strong magnetic field equipment.
2、Measurement error is too large
Reason analysis: inaccurate sensor installation position; sensor zero drift; wear and tear of mechanical parts leading to changes in the measurement reference.
Solution: reinstall the position sensor to ensure the accuracy of the installation; zero calibration and precision adjustment of the sensor; check the mechanical components, replace the parts of serious wear and tear to restore the measurement reference.
Third, the pressure sensor failure
1、Pressure display abnormality
Reason analysis: improper selection of the range of the pressure sensor; sensor diaphragm damage; signal amplification circuit failure.
Solution: according to the actual pressure range to choose the appropriate range of pressure sensors; replace the damaged diaphragm or the entire pressure sensor; check the signal amplification circuit, repair or replacement of faulty components.
2, inaccurate pressure detection
Reason analysis: the pressure sensor corroded or contaminated by the medium; improper installation location, resulting in uneven pressure transfer; sensor performance degradation after long-term use.
Solution: Clean the pressure sensor or replace the anticorrosive sensor; adjust the installation position to ensure that the pressure is transmitted evenly; regular calibration of the pressure sensor and performance testing, timely replacement of the sensor performance decline.
