Adjustable Insertion Head for Leaded Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion heads apply a constant gripping force regardless of the size, weight, or surface roughness of leaded components, leading to concerns of components being either dropped due to insufficient force or damaged by excessive force.
Innovation Solution
An insertion head with a horizontal shaft, gripping claws, and an interval changing mechanism that adjusts the distance between the claws, allowing for variable gripping force based on the component's characteristics, controlled by a swing mechanism and recognition system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a constant gripping force is applied by the insertion head, then the structure is simple and operation is easy, but the leaded component may be dropped due to insufficient force or damaged by excessive force
Solution Approach 1:
The gripping force is made dynamic and adjustable rather than constant. The interval between gripping claws is changed based on component characteristics (size, weight, surface roughness) to adapt the gripping force to different leaded components, ensuring reliable gripping without damage while maintaining manageable system complexity through controlled adjustment mechanisms.
2Adaptability or versatility
If the interval between gripping claws is adjusted for different components, then gripping force becomes adaptable, but the device complexity increases
Solution Approach 1:
The physical parameter of the gripping system (interval between claws) is changed to adapt to different leaded components. By adjusting this interval based on component characteristics, the system achieves versatile gripping capability across different component types while managing complexity through parameter-based control rather than completely different mechanisms for each component type.

AI summary
An insertion head includes: a horizontal shaft member; one pair of gripping claws, each gripping claw extending on a surface which is orthogonal to the horizontal shaft member; one pair of gripping claw holding members which are provided to be movable on the horizontal shaft member, and hold the one pair of gripping claws; a swing mechanism which rotates and drives the horizontal shaft member, and swings the one pair of gripping claw holding members around a center axis of the horizontal shaft member; and an interval changing mechanism which moves the one pair of gripping claw holding members on the horizontal shaft member and changes an interval between the one pair of gripping claws. A gripping force of the leaded component by the one pair of gripping claws is changed by performing an interval changing control of the one pair of gripping claws via the interval changing mechanism.
