AI Technical Summary
In existing electric actuator sealing testing devices, dust, oil, and other contaminants in the testing chamber can easily adhere to the sensor probe, causing a decrease in probe sensitivity and making it impossible to accurately sense changes in air pressure and sound, thus affecting the testing results.
An electric actuator sealing detection device was designed. A cleaning sponge is used to continuously wipe the sensor probe. A motor drives a lead screw to move a fixed block and the cleaning sponge along a guide rod. Combined with the design of springs and slide bars, the cleaning sponge is ensured to fit tightly against the probe surface. The device is used in conjunction with a PLC controller to achieve automated control and ensure the accuracy and stability of the detection.
It effectively removes contaminants from the sensor probe, improves detection accuracy, reduces false positive rate, and achieves efficient and automated sealing performance evaluation.
