Title Design of Workpiece Handling System for Flexible
Gripper
Abstract
The Workpiece Handling System for Flexible Gripper was designed in this work, the system can carry workpieces which are fragile, easily deformed and irregular shape autonomously.
This work introduces the types and the current situation at home and abroad of the Pneumatic manipulator. According to the requirements of the task book,the overall conceptions of the Workpiece Handling System was advanced. A king of Flexible Grippers was analysed and ameliorated, through the selection of analysis, calculation and determine the Cartesian motion arm and gantry type overall frame were proposed by calculating and analyzing. 3D model was established for motion simulation. According to control requirements, SIEMENS S7-200 PLC-CPU226 and magnetic valve were selected, the control circuit was set up and corresponding program was written too. Parts were processed to complete assembly of Pneumatic manipulator entity.
The test showed that the system can realize the function of carrying workpieces which are fragile, easily deformed and irregular shape better.
Keywords Pneumatic Workpiece Handling System Flexible Gripper PLC Controller
