Title Design of Apple Boxing Manipulation
Abstract
With the development of modern industrial manufacturing, the industrial manipulator is increasingly becoming the essential operation tool assisted machining production and transportation of a series of work. Now, more and more people focus their attentions to the manipulator technology. And the universal degree of manipulators is higher than before. This technology has penetration into all aspects of human. The main purpose of this paper is to design a kind of boxing manipulation for a fruit company instead of human.
I make the motion analysis of the packing process, and design the overall structure of the manipulation, and calculate the force on each part of the manipulation. Then I choose the appropriate hydraulic system according to the force situation and make detailed design and verification. Besides, I choose the gripper of the manipulation.
Manipulation is the integration of pneumatic and hydraulic drive ways. It uses the cylindrical coordinate system and involves three degrees of freedom, a rotation degree of freedom, a elevating degree of freedom and a translational degree of freedom. The manipulation can make the apple catched move through these and a gripper.The manipulation can meet the requirement of boxing.
