Development of a Kind of Miniature Pressure and Vacuum Compressor for Built-In Robot Wrist
This paper deals with a new type of miniature air compressor which mainly consists of a stepper motor, a pneumatic swing cylinder, and four small high-speed ON/OFF solenoid valves. By switching the four ON/OFF solenoid valves properly, the miniature air compressor can produce both pressure and vacuum. The pressure and vacuum characteristics of the developed compressor are experimentally investigated. Furthermore, the performance of working as a air compressor or a vacuum pump freely are proven by experiment results.
