Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing insertion heads for component insertion devices are bulky and heavy due to freely swinging gripping claws and adjustable supporting members, which hinders their compactness and efficiency.

Innovation Solution

The insertion head incorporates a horizontal shaft with gripping claws that are held by movable claw holding members, a swing mechanism to rotate the holding members, and an interval changing mechanism to adjust the claw spacing, allowing for compact design and efficient component gripping and insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If freely swinging gripping claws with adjustable supporting members are used, then the insertion head can grip components in various orientations, but the size and weight of the insertion head increase

Engineering Contradiction:

Improveability to grip components in various orientationsVSAvoidsize of insertion head

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The gripping claws are designed to swing freely around a fixed center axis without requiring adjustable supporting members. This dynamic design allows the claws to adapt to different component orientations while maintaining a fixed, compact structure, resolving the contradiction between versatility and size

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The single fixed center axis serves as the universal rotation point for both gripping claws, allowing them to handle various component orientations simultaneously. This multi-functional design eliminates the need for separate adjustable supporting members for each claw, reducing overall size while maintaining adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If freely swinging gripping claws with adjustable supporting members are used, then the insertion head can grip components in various orientations, but the weight of the insertion head increases

Engineering Contradiction:

Improveability to grip components in various orientationsVSAvoidweight of insertion head

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The gripping claws utilize free swinging motion around a fixed center axis, eliminating the need for heavy adjustable supporting members. This dynamic approach reduces weight while preserving the ability to grip components in various orientations

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent extracts and eliminates the adjustable supporting members from the system, relying instead on the free swinging capability of the gripping claws around a fixed center axis. This removal of unnecessary components directly reduces the weight of the insertion head while maintaining functional versatility

Inventive Principle:

Principle #2Taking out (Extraction)

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 leaded component is gripped with the one pair of gripping claws, and a lead of the leaded component is inserted into an insertion hole on a printed circuit board.
