Perpendicular Rotary Turret and Wheel for Compact Package Handler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional package handlers for semiconductor devices require a large machine footprint due to the horizontal disposition of their transfer mechanisms, limiting the efficient use of three-dimensional space and accommodating fewer processing devices.
Innovation Solution
The package handler optimizes three-dimensional space by arranging the rotary turret and rotary wheel perpendicularly, allowing for more device holders on the rotary wheel and positioning processing components above or below the horizontal plane, reducing the machine footprint and enabling more processing devices within the same space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the transfer mechanism is disposed horizontally, then the transfer mechanism can be simple in structure, but the machine footprint becomes large
Solution Approach 1:
The rotary wheel is tilted at an acute angle θ (0° < θ < 90°) with respect to the rotational plane of the rotary turret, transitioning from a purely horizontal arrangement to a three-dimensional configuration. This dimensional change allows the transfer mechanism to utilize vertical space, reducing the horizontal footprint while maintaining functional simplicity
2Area of stationary object
If the machine footprint is reduced, then the space utilization is improved, but the number of processing devices that can be accommodated is limited
Solution Approach 1:
By tilting the rotary wheel at an acute angle, the system creates three-dimensional space utilization that allows more device holders to be arranged on the rotary wheel without increasing the horizontal footprint, thereby accommodating more processing devices in a compact configuration
Solution Approach 2:
The tilted rotary wheel configuration allows processing devices to be nested more efficiently within the available space, with device holders arranged concentrically on the outer edge of the rotary wheel, maximizing the use of both horizontal and vertical dimensions

AI summary
An apparatus for processing electronic devices includes a rotary turret having first device concentric around the rotary turret, which transfer the electronic devices; a rotary wheel having second device holders concentric around the rotary wheel, which receive the electronic devices and a processing device to process the electronic devices. The rotary turret rotates the first device holders along a first circular path, and the rotary wheel rotates the second device holders along a second circular path. The first axis of the rotary turret is perpendicular to the second axis of the rotary wheel, and that a projection of the second circular path of the second device holders in a direction perpendicular to the second axis of the rotary wheel onto the first circular path of the first device holders defines a line from the inside to the outside of the first circular path of the first device holders.
