Asymmetric Gripping Claw for Stable Component Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component insertion devices face challenges in stably gripping leaded components of varying postures, as large swing angles of gripping claws can lead to interference with adjacent components, making it difficult to maintain stable gripping during the insertion process.
Innovation Solution
The insertion head incorporates a horizontal shaft member, gripping claws, gripping claw holding members, a swing mechanism, and an interval changing mechanism, allowing the gripping claws to be rotated and their interval adjusted, enabling stable gripping of leaded components regardless of posture by offsetting the tip end straight line portion relative to the perpendicular axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the swing angle from perpendicular posture of the gripping claws is large, then the gripping claws can grip leaded components in non-standing postures, but the part near the swing shaft may interfere with adjacent leaded components
Solution Approach 1:
The gripping claw is designed with an asymmetric bent shape where the tip end straight line portion is offset from the perpendicular axis through the swing shaft center axis. This asymmetric configuration allows the gripping claw to achieve large swing angles for gripping components in various postures while the offset tip end prevents interference with adjacent components during the swinging motion
Solution Approach 2:
The gripping claw incorporates a bent shape with curved geometry rather than a straight configuration. The tip end straight line portion is offset from the swing shaft center axis, creating a curved path during swinging that enables large angular movement while maintaining clearance from adjacent components, thus resolving the interference issue
2Ease of manufacture
If the gripping claws extend straightly downward, then the structure is simple, but the leaded component must be supplied in standing posture only
Solution Approach 1:
The gripping claw is designed with a bent shape that enables dynamic adaptation to different component postures. The offset tip end straight line portion relative to the swing shaft center axis allows the gripping claw to swing through large angles and grip components in various postures (standing, non-standing, horizontal), transforming the static straight configuration into a dynamic adaptable structure
Solution Approach 2:
The gripping claw extends not only vertically downward but also has a horizontal offset component. The tip end straight line portion is offset from the perpendicular axis through the swing shaft center axis, adding a horizontal dimension to the gripping capability. This dimensional extension enables the gripping claw to accommodate components in various postures while maintaining structural simplicity

AI summary
An insertion head includes: a horizontal shaft member; one pair of gripping claws, extending on a surface orthogonal to the horizontal shaft member; one pair of gripping claw holding members movable on the horizontal shaft member which hold the one pair of gripping claws; a swing mechanism which rotates and drives the shaft member, and swings the one pair of gripping claw holding members around a center axis of the shaft member; and an interval changing mechanism which moves the one pair of gripping claw holding members on the shaft member and changes an interval between the one pair of gripping claws. The gripping claw extends to be bent on the surface, and each straight line portion of each tip end is offset to a perpendicular axis extending on the surface through a center axis of the shaft member in a posture of being oriented downward.
