Multistage Sliding Manipulator for Compact Long-Distance Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manipulator systems for transferring objects like glass panels and wafers lack compactness and rapid transfer capabilities, limiting their ability to cover long distances within a small installation space.
Innovation Solution
A manipulator apparatus with a multistage sliding structure comprising three movable members, where each member can extend or collapse to achieve a longer transfer distance while minimizing space, utilizing a pinion gear unit as a link mechanism to facilitate efficient movement and reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a conventional manipulator system is used, then the installation space is occupied, but the transfer distance is limited and the size is large
Solution Approach 1:
The manipulator apparatus employs a nested multistage sliding structure where the first member slides relative to the second member, and the second member slides relative to the third member. This nesting arrangement allows the manipulator to achieve a long transfer distance when extended, while occupying minimal installation space when retracted, effectively resolving the contradiction between transfer distance and installation space.
Solution Approach 2:
The invention transitions from a single-linear-motion manipulator to a multistage sliding structure that operates in multiple dimensional directions. The first member provides motion in one direction, while the second and third members provide additional motion in perpendicular directions, creating a three-dimensional transfer capability that increases transfer distance without proportionally increasing installation footprint.
2Speed
If a conventional manipulator system is used, then the structure is simple, but the transfer speed is slow and energy consumption is high
Solution Approach 1:
The manipulator is segmented into multiple independent sliding members (first member, second member, third member), each capable of independent motion control. This segmentation allows for optimized speed control at different stages of the transfer process, enabling rapid transfer while reducing energy consumption by only activating necessary sliding stages rather than moving the entire structure uniformly.
Solution Approach 2:
The multistage sliding structure enables dynamic adjustment of transfer speed and motion profile. Each member can slide at different speeds and can be independently controlled to optimize the transfer process, allowing rapid transfer when needed while minimizing energy consumption during positioning and idle periods.
