Component Feeder with Dual Lead Cutting for Three-Lead Radial Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no existing technology that effectively supplies radial components with three leads to a specified supply position while cutting the center lead shorter than the outer leads, which is necessary for efficient component mounting.
Innovation Solution
A component feeder equipped with a feeding mechanism and dual lead cutting mechanisms: one for cutting the outer leads to a specific length and another for cutting the center lead to a shorter length before the outer leads are cut, ensuring appropriate supply positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single lead cutting mechanism is used to cut all leads, then the device complexity is reduced, but it cannot accommodate components with different lead lengths (center lead shorter than outer leads)
Solution Approach 1:
The lead cutting function is divided into two separate mechanisms: a first lead cutting mechanism for cutting outer leads and a second lead cutting mechanism for cutting the center lead. This segmentation allows each mechanism to be optimized for specific cutting positions and lengths, enabling the system to handle components with different lead length requirements without increasing overall system complexity excessively.
Solution Approach 2:
The second lead cutting mechanism performs preliminary cutting of the center lead before the first lead cutting mechanism cuts the outer leads. This preliminary action ensures that the center lead is already at the correct shorter length before the outer leads are cut, preventing interference and ensuring proper final dimensions.
2Ease of manufacture
If the center lead is cut to the same length as outer leads, then the cutting process is simplified, but it prevents proper mounting of components requiring different lead lengths
Solution Approach 1:
Different cutting lengths are applied to different leads based on their specific requirements: the center lead is cut to a shorter second length while outer leads are cut to a longer first length. This local differentiation in cutting quality ensures each lead meets its specific mounting requirements while maintaining an efficient cutting process through dedicated mechanisms.
3Manufacturing precision
If leads are cut before feeding components to the supply position, then the mounting precision is improved, but the device complexity increases due to additional cutting mechanisms
Solution Approach 1:
The feeding mechanism is merged with dual lead cutting mechanisms, where the second lead cutting mechanism is positioned in the feeding path before the supply position and the first lead cutting mechanism operates at the supply position. This merging integrates cutting functions into the feeding process, ensuring leads are cut to precise lengths before components reach the supply position, thereby improving mounting precision while consolidating functions.

AI summary
A component feeder including a feeding mechanism configured to intermittently feed taped components in a feeding direction at a specified feeding pitch to a supply position; first lead cutting mechanism configured to, for separating the component positioned at the supply position from the carrier tape, in a case in which the component has three leads, cut two of the leads Leo that are on an outer side of the three leads at a given position such that a length by which the two leads protrudes from the component main body is a first length; and second lead cutting mechanism configured to, before the cutting of the two leads by the first lead cutting mechanism, cut a single lead that is at a center of the three leads positioned forward of the supply position in the feeding direction to a second length that is shorter than the first length.
