Robotic Collet and Ejector Hood Replacement for Continuous Die Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing die bonding processes are hindered by the need to frequently stop operations for manual replacement of collets and ejector hoods, leading to decreased productivity due to the time-consuming nature of these manual replacements.
Innovation Solution
An apparatus with a cabinet unit, replacement robots, and a shutter mechanism that allows for automatic replacement of collets and ejector hoods without stopping the die bonding equipment, using a sliding movement system and robots to manage collet and ejector hood accommodation parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual replacement of collets and ejector hoods is performed, then the replacement process is simple and flexible, but the die bonding process must be stopped frequently, reducing productivity
Solution Approach 1:
The system enables automatic replacement of collets and ejector hoods through a robotized mechanism that operates independently without human intervention. The robot withdraws used components from the cabinet unit and replaces them with new ones, allowing the die bonding process to continue without stopping.
Solution Approach 2:
Multiple new collets and ejector hoods are pre-loaded into the cabinet unit before the die bonding process begins. This preliminary preparation ensures that when components need replacement, they are already available in the cabinet, enabling quick automatic replacement without process interruption.
2Productivity
If multiple collets are loaded in advance onto the panel, then replacement frequency is reduced, but the panel structure becomes more complex and space-consuming
Solution Approach 1:
Multiple collets are nested vertically within the cabinet unit, with several collets stacked one above another in a compact arrangement. This nesting approach allows multiple components to be stored in a small space without increasing the horizontal footprint or overall system complexity.
Solution Approach 2:
Instead of arranging multiple collets horizontally on the panel, the system utilizes the vertical dimension by stacking collets vertically within the cabinet unit. This dimensional transition from horizontal to vertical arrangement reduces the panel area required and simplifies the overall structure.
