Crank-Driven Handler Posture Switching for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handlers for device processing are complex and costly due to the need for multiple directional movement to prevent interference between transfer and processing mechanisms, leading to increased manufacturing costs.
Innovation Solution
A handler comprising a processing unit, a first driving unit, a holding unit, a crank unit, and a second driving unit, which allows the handler to be in two postures: one where the holding unit is inside the movement path and the processing unit is outside, and another where the processing unit is near the device, reducing structural complexity and cost.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the device is moved to the vicinity of the processing mechanism through multiple directions or a sufficiently long distance, then interference between transfer and processing mechanisms is prevented, but the structure of the handler becomes complex and manufacturing cost increases
Solution Approach 1:
The patent applies the dynamics principle by enabling the holding unit to switch between two postures: a first posture where it is located inside the movement path for transfer operations, and a second posture where it is located outside the movement path for processing operations. This dynamic repositioning allows the same structure to avoid interference in different operational contexts, eliminating the need for complex multi-directional movement paths or excessively long distances.
Solution Approach 2:
The patent segments the handler into distinct functional units (processing unit, holding unit, crank unit, driving units) that can independently position themselves. The holding unit is specifically designed to be detachably connected to the crank unit, allowing it to be positioned inside or outside the movement path as needed. This segmentation enables flexible configuration to avoid interference without requiring complex overall structure.
2Productivity
If the holding unit is located inside the movement path, then transfer efficiency is improved, but interference with the processing mechanism occurs
Solution Approach 1:
The holding unit is designed with dynamic positioning capability, allowing it to adopt a first posture inside the movement path during transfer operations to maximize productivity, and switch to a second posture outside the movement path during processing operations to eliminate interference. This dynamic adaptation enables the system to optimize for different operational phases without compromise.
Solution Approach 2:
The system performs preliminary repositioning of the holding unit before processing operations begin. By switching to the second posture (outside the movement path) in advance, the holding unit prevents interference with the processing mechanism before any processing action occurs, ensuring smooth operation transitions.

AI summary
A handler has a processing unit, first and second driving units, a holding unit and a crank unit. The processing unit processes a device provided in a placement area. The first driving unit moves the processing unit along a movement path. The holding unit holds the device and is attached to the crank unit. The second driving unit moves the holding unit. The crank unit comprises a first portion to which the holding unit is attached and a second portion connected to the first portion. The handler is allowed to be in a first posture for causing the holding unit to be located inside the movement path and to be in a second posture for causing the processing unit to be located in vicinity of the device.
