Horizontal Turret Die Handler With Direct-Drive Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component handlers in the semiconductor industry face issues with high frictional forces due to high rotational speeds, which prematurely shorten the life span of cam and follower mechanisms, leading to inefficiencies in handling and transferring semiconductor dies.
Innovation Solution
A rotatable turret system with end effectors aligned radially around a horizontal axis, supported by a vertical support assembly and component transfer medium, allowing continuous picking and placement of semiconductor dies between these components, reducing friction and extending the life span of mechanical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high rotational speeds are used in the flipper mechanism, then component transfer speed increases, but frictional forces on the cam and follower mechanism increase, shortening its lifespan
Solution Approach 1:
The patent replaces the traditional cam and follower mechanism with a direct-drive motor system. The motor is directly coupled to the flipper shaft, eliminating the need for cam mechanisms. This substitution removes the source of high frictional forces while maintaining the high rotational speeds needed for efficient component transfer, thereby resolving the contradiction between speed and mechanism lifespan.
2Productivity
If high rotational speeds are used, then throughput increases, but wear on mechanical components increases
Solution Approach 1:
The direct-drive motor system replaces complex mechanical transmission mechanisms, reducing moving parts and friction points. This allows sustained high rotational speeds for improved throughput without the wear problems that would otherwise limit component lifespan.
3Device complexity
If a cam and follower mechanism is used for rotation, then structural compactness is achieved, but frictional forces increase due to high speeds
Solution Approach 1:
The motor directly coupled to the flipper shaft eliminates the cam and follower mechanism entirely. This substitution removes the harmful frictional forces generated by high-speed cam operation while maintaining a relatively simple and compact structure through direct coupling.

The present disclosure relates to a system (100) for handling components (102). The system (100) comprises a turret assembly (200) comprising a turret (202) rotatable about a horizontal axis (204); and a plurality of end effectors (206) around the turret (202) and aligned radially from the horizontal axis (204). The system (100) further comprises a support assembly (300) arranged to support a source substrate (302) comprising singulated components (102); and a component transfer assembly (400) arranged to support a component transfer medium (402) for receiving the singulated components (102) from the end effectors (206). The turret assembly (200), support assembly (300), and component transfer assembly (400) are arranged vertically to each other. During rotation of the turret (202), 200 the end effectors (206) continually pick the singulated components (102) from the source substrate (302) and place the picked singulated components (102) on the component transfer medium (402).
