Component Feeder Lead Positioning Clamp Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component feeders face challenges in efficiently supplying components with leads held on a carrier tape, particularly in accurately positioning and cutting leads to appropriate lengths, and detecting bent or mispositioned leads, which affects the reliability and efficiency of the feeding process.
Innovation Solution
A component feeder with a positioning mechanism that includes a clamp with a guide section and a lead cutting mechanism, along with a clamp closed position checking mechanism, to accurately position and cut leads, and detect inappropriate lead positions or bending, ensuring proper alignment and length adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamp is used to position leads without a checking mechanism, then the device complexity is reduced, but the reliability of lead positioning deteriorates because bent or mispositioned leads cannot be detected
Solution Approach 1:
The patent implements a clamp closed position checking mechanism that provides feedback on whether the clamp has successfully closed around the leads. This feedback system detects the closed position of the clamp and can identify when leads are bent or mispositioned, thereby improving positioning reliability without requiring complex additional mechanisms. The checking mechanism uses simple position detection to provide critical feedback about lead positioning accuracy.
2Manufacturing precision
If multiple leads are guided to the same defined position, then the positioning precision is improved, but the reliability deteriorates because it becomes impossible to detect when multiple leads occupy the same space
Solution Approach 1:
The clamp closed position checking mechanism provides feedback that can detect when multiple leads are present at the same position. By monitoring the closed position of the clamp and comparing it against expected parameters, the system can identify anomalies such as multiple leads occupying the same space, thereby maintaining detection reliability even when multiple leads are guided to the same defined position.

AI summary
A component feeder includes a feeding mechanism which feeds taped components in which components with leads having a plurality of leads are held on a carrier tape by the plurality of leads, and a positioning mechanism which positions each of the plurality of leads included in the component at the supply position. The positioning mechanism includes a clamp which is configured to include a first member and a second member that are operated relative to each other, and a guide section which guides each of the plurality of leads to a defined position in a feeding direction of the taped component when the plurality of leads are pinched by the clamp. The component feeder includes a clamp closed position checking mechanism for checking whether or not a closed position which is an operation position of the clamp in a state where the clamp is closed is an appropriate position.
