Probe Head Horizontal Fine Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional probe heads face challenges in aligning probes due to position alignment issues and flattening processes, which can cause probes to be partially displaced and abut against the inner walls of die units at incorrect positions, preventing proper installation.
Innovation Solution
A probe head design featuring adjustable die units with detachable inner and outer dies, allowing for horizontal fine adjustment of the outer die relative to the middle die, enabling the probes to be aligned correctly by loosening and re-tightening bolts, ensuring proper positioning and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the probes are installed and flattening processing is performed, then the probes are secured in position, but the probes become partially displaced and abut against the inner wall of the probe holes at incorrect positions
Solution Approach 1:
The die unit is designed with adjustable characteristics, allowing the position of the die relative to the probe holes to be modified. This dynamic adjustment capability enables correction of probe displacement after flattening processing by repositioning the die unit horizontally along the probe installation surface.
Solution Approach 2:
The horizontal position parameter of the die unit can be changed through adjustable mechanisms. By modifying the positional parameter of the die unit relative to the probe holes, the alignment between probes and probe holes can be corrected after flattening processing causes displacement.
2Ease of manufacture
If the die units are fixed in position, then the structure is simple and stable, but position alignment problems prevent proper probe installation
Solution Approach 1:
The die unit incorporates adjustable characteristics that allow horizontal movement along the probe installation surface. This dynamic feature enables position alignment adjustments to facilitate proper probe installation while maintaining structural simplicity through the use of standard adjustable mechanisms.
3Strength
If the probes are abutted against the inner wall of the probe holes, then the probes are supported, but the probes are at positions not meeting the requirement
Solution Approach 1:
The adjustable die unit can be repositioned horizontally to correct probe alignment. When probes are improperly supported against the inner wall, the die unit's adjustable mechanism allows horizontal movement to realign the probe holes with the probes, ensuring both proper support and accurate positioning.

AI summary
A probe head includes a middle die, upper and lower die units, at least one of which includes inner and outer dies detachably fastened to the middle die and each other, and a plurality of buckled probes inserted through the upper and lower die units. The inner die has an outer connecting surface connected with an inner surface of the outer die, where an installation recess is provided, an inner connecting surface connected with the middle die, and a probe installation section having a protruding portion protruding from the outer connecting surface and located in the installation recess, and a recessed portion recessed from the inner connecting surface and located correspondingly to the protruding portion. The protruding portion and the installation recess have a horizontal distance therebetween. Therefore, the outer die is horizontally fine adjustable to make the positions of the probes meet the requirement.
