Independent Slide Transfer Head for Precise Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatus for transferring electronic components, such as semiconductor components, are limited in mounting efficiency due to the lack of independent movement of the membrane holder and needle head relative to the components.
Innovation Solution
The apparatus includes a second slide with a needle head arranged on the cross member, allowing independent movement of the membrane holder and needle head in the X direction using separate drives, enhancing the precision and efficiency of component transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single slide is used to move both the membrane holder and needle head, then the device structure is simpler, but the mounting efficiency is reduced due to lack of independent movement
Solution Approach 1:
The single slide is divided into two independent slides (first slide for membrane holder, second slide for needle head), each capable of independent movement along the X-axis. This segmentation allows simultaneous or independent positioning operations, eliminating the need for sequential movement and thereby improving mounting efficiency without excessive complexity increase
2Manufacturing precision
If the membrane holder and needle head are moved together as one unit, then the control system is simpler, but the positioning precision is reduced
Solution Approach 1:
The control system is segmented into independent control units for the first slide (membrane holder) and second slide (needle head). Each slide can be controlled independently along the X-axis, allowing precise positioning of the needle head relative to the membrane holder without being constrained by coupled movement, thereby achieving higher positioning precision
3Productivity
If additional cross members are added to double production speed, then the productivity increases, but the device complexity and space requirements increase
Solution Approach 1:
Instead of adding cross members along the X-axis which would increase installation space, the patent utilizes the Y-axis dimension by providing a further cross member that can be moved independently on the same two rails. This vertical stacking approach allows dual production lines without significantly increasing the horizontal footprint, effectively doubling production speed while minimizing space requirements
