Adjustable Claws for Axial Component Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting devices face challenges in accurately delivering axial components to the mounting head, leading to potential component fallout during the delivery process.
Innovation Solution
A component mounting device equipped with a movable forming-die that lifts leads in a bent state, guided by a fixed forming-die, and a mounting head with adjustable claws that set a larger distance initially to secure the component before retracting the die, ensuring accurate delivery and secure clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable forming-die delivers the axial component to the mounting head, then the component can be transferred to the mounting head, but the component may fall off due to downward movement of the die
Solution Approach 1:
The mounting head's claw distance is made adjustable rather than fixed, allowing the system to dynamically adapt the clamping geometry to match the component geometry at different stages of the process. This dynamic adjustment ensures reliable component delivery while preventing fallout during die retraction.
Solution Approach 2:
The distance between the claws is changed as a variable parameter - set larger during delivery to accommodate the component from the forming-die, then adjusted to a smaller distance for secure clamping. This parameter change resolves the contradiction between enabling delivery and preventing fallout.
2Ease of operation
If the distance between claws is set larger to accommodate fixed forming-die distance, then component delivery is facilitated, but clamping force may be reduced
Solution Approach 1:
The claw distance adjustment mechanism allows the system to transition from a larger distance configuration during delivery to a smaller distance configuration for clamping. This dynamic change enables the system to optimize for delivery ease first, then for clamping force, resolving the contradiction between these two requirements.

AI summary
A component mounting device configured to mount an axial component on a substrate, comprising: a movable forming-die; a fixed forming-die; a mounting head; and a distance adjustment portion, wherein the distance adjustment portion makes an adjustment such that when the movable forming-die delivers the axial component to the mounting head the distance between the claws is larger than a distance of the fixed forming-die.
