Abstract:According to the requirement of an enterprise that the impurities such as residual liquid and shavings were cleaned automatically after machining for the small and medium-sized parts with complex structure in automobile industry ， an automatic low noise cleaning device was developed to improve parts cleanliness qualification rate ， to reduce the labor intensity of operating staff ， to control the noise of cleaning process and to improve the working environment of staff. The device adopted multi-angle and multi-air jet with multiple flexible tubes to clean the parts ， and adopted the closed structure composed of multi-layer sound insulation and sound absorbing materials to reduce working noise. The control and human-machine interaction systems were composed of programmable logic controller（ PLC ） and touch screen ， the integrated control systems were designed ， and the control program and human-machine interface were designed. The test results showed that the cleaning effect was good ； After the parts were cleaned once by the device， the qualified rate of particle impurities（ ≤5 mg）reached 87% ， and the qualification rate of liquid impurities（ ≤0.5 mg）was 100% . The noise value during the operation of the device was no more than 80 dB ， so the working noise of cleaning process was effectively controlled. The device realized a high degree of automation ， and could set the time of automatic cleaning program according to the actual production line to meet practical needs.
