Component Gripper Claw Layout for Inclined Pin Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component gripping tools face difficulties in properly gripping electronic components with inclined pins or leads due to interference between the claws and contact surfaces, leading to inadequate gripping and mounting efficiency.
Innovation Solution
A component gripping tool with a pair of claws and a contact surface that includes an escape section to prevent interference, allowing the claws to close and grip multiple pins or leads without obstruction, ensuring appropriate contact and gripping of electronic components even when they are supplied in an inclined state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact surface is provided between the pair of claws to contact the leading end of pins or leads, then the gripping stability is improved, but the claws and contact surface interfere with each other when gripping inclined components
Solution Approach 1:
The contact surface is segmented into a first contact surface and a second contact surface positioned at different heights. This segmentation allows the tool to accommodate pins of varying lengths and angles, enabling stable contact with at least two pins simultaneously while preventing interference between the claws and contact surfaces during gripping operation.
Solution Approach 2:
The contact surfaces are arranged in different vertical dimensions (heights) rather than on a single plane. This dimensional arrangement allows pins to contact the appropriate surface based on their length and inclination, resolving the interference problem while maintaining gripping stability for components supplied at angles.
2Productivity
If the claws are designed to grip multiple pins or leads, then the productivity is improved, but interference between claws and contact surface occurs with inclined components
Solution Approach 1:
By dividing the contact surface into multiple segments at different heights, the tool can simultaneously contact multiple pins of an electronic component even when they are inclined. This ensures reliable gripping of multiple pins without interference, maintaining both productivity and gripping accuracy.
Solution Approach 2:
Different portions of the contact surfaces are designed with different heights to match the local requirements of pins at different positions. This local differentiation ensures that each pin can make proper contact without causing interference between the claws and contact surfaces, enabling accurate gripping of inclined components.

AI summary
A component gripping tool including: a pair of claws configured to grip multiple pins or leads of an electronic component; a contact surface provided between the pair of claws and configured to contact a leading end of at least two of the multiple pins or leads being gripped by the pair of claws, wherein an escape section is formed in the contact surface such that the pair of claws and the contact surface do not interfere with each other when the pair of claws is gripping the two multiple pins or leads.
