Ultrasonic cleaning machine as an important industrial cleaning equipment, its cleaning efficiency and cleaning effect has become a key concern. If the workpiece cleaning effect is not good, will affect the secondary processing of the workpiece, therefore, people need to study the ultrasonic cleaning machine can monitor the cleaning effect of the method to ensure that the workpiece cleaning effect is good. According to the research of our experts, can be used to hair glass piece method, aluminum foil test method and ultrasonic energy bottle detection method to detect the cleaning effect of the workpiece.
In the use of aluminum foil test method to monitor the cleaning effect of ultrasonic cleaning machine found that the 10μm aluminum foil paper in the test is more serious damage, can not judge the cleaning effect, and other thicknesses of the aluminum foil test the qualification rate of the gap is relatively small. Through monitoring tests, it was found that when aluminum foil paper with a thickness of more than 20μm was used as a testing tool, the cleaning effect was more obvious and it was easier to monitor. When monitoring the cleaning effect of ultrasonic cleaning machines using hair glass pieces or ultrasonic energy bottles, it was found that the size of the monitored items did not affect the monitoring effect, but the placement position would have some influence. In order to ensure the accuracy of the monitoring, need to be based on the cleaning time, cleaning temperature and cleaning frequency design of different test groups, and the number of tests in each group to meet the relevant requirements.
When people use three methods to monitor the cleaning effect of ultrasonic cleaning machine at the same time, it was found that the aluminum foil test method and ultrasonic energy bottle detection method of monitoring the pass rate is significantly lower than that of the hair glass sheet method, the monitoring results are more accurate. It can be seen that the aluminum foil test method and ultrasonic energy bottle test method is more suitable for monitoring the cleaning effect of ultrasonic cleaning machine, if the conditions do not allow people to settle for the second best choice of the hair glass piece method, and will be placed in the four corners of the hair glass piece of the cleaning machine vertical position, to improve the monitoring of the difficulty.
