Lead Wire Cutting Unit Fiducial Alignment for Multi-Lead Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lead wire cutting units face challenges in accurately positioning multiple lead wires for effective cutting due to variations in the relative position of fiducial marks and cutting blades, leading to reduced positioning accuracy.
Innovation Solution
The implementation of fiducial marks on cutting blade holding members, with pre-determined relative position information stored, allows for precise determination of cutting blade positions, enhancing the accuracy of lead wire positioning and cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple cutting blades are used to cut multiple lead wires, then the productivity is improved, but the positioning accuracy deteriorates due to variations in relative position of fiducial marks and cutting blades
Solution Approach 1:
The cutting system is divided into multiple independent cutting blades, each capable of cutting individual lead wires. This segmentation allows simultaneous cutting of multiple lead wires, improving productivity while maintaining positioning accuracy through individual blade control and separate fiducial mark references.
Solution Approach 2:
Fiducial marks are introduced as intermediary reference elements between the cutting blades and the lead wires. These marks serve as mediators for position alignment, allowing the system to accommodate variations in blade positions while maintaining accurate positioning of each blade relative to its target lead wire.
2Manufacturing precision
If fiducial marks are provided on cutting blade holding members, then the positioning accuracy is improved, but the device complexity increases
Solution Approach 1:
The fiducial marks are designed with distinct visual characteristics that enable easy detection and recognition by the imaging device. This allows for simple visual or optical identification of blade positions and alignment references, improving positioning accuracy without requiring complex sensing or measurement systems.

AI summary
A problem to be solved by the present disclosure is how to improve a lead wire cutting unit and a mounter provided with the lead wire cutting unit and more particularly, for example, how to enable multiple lead wires of a lead component to be cut well. In the lead wire cutting unit according to the present disclosure, at least one fiducial mark is provided on each of one or more of multiple cutting blade holding members for holding multiple cutting blades. In addition, since the relative position between each of the at least one fiducial mark and the one or more cutting blades is determined in advance, in case that a position of the fiducial mark can be acquired, positions of the one or more cutting blades are determined based on the position so acquired and the relative position. The positioning accuracy of the multiple lead wires with respect to the one or more cutting blades can be improved, thereby making it possible to cut the multiple lead wires well.
