Lead Component Mounting Sequence to Avoid Tool Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting methods face inefficiencies when holding leads with a tool, as they can damage previously attached components and require tool exchanges due to varying lead pitches, leading to reduced mounting efficiency.
Innovation Solution
A data creation device and method that determine the optimal installation order for holding tools based on lead component shape data and mounting data, ensuring interference-free mounting and minimizing tool exchanges by creating allocation data for the mounting machine.

Engineering Contradiction Analysis
1Productivity
If the holding tool moves in the left-right direction or rear direction to press the component toward the board, then the component can be mounted, but the holding tool may contact previously-attached components and cause damage
Solution Approach 1:
The system performs preliminary analysis of the holding tool's movement trajectory before mounting occurs. The calculation unit computes the moving trajectory of the holding tool based on the component's position and the holding tool's configuration, and determines in advance whether the trajectory will intersect with previously-attached components. This allows the system to prevent damage by selecting alternative mounting sequences or adjusting trajectories before the actual mounting operation begins.
Solution Approach 2:
The system uses feedback from the trajectory calculation and intersection detection to adjust the mounting process. When the calculation unit detects that the holding tool's trajectory would contact previously-attached components, the system feeds this information back to modify the mounting sequence or trajectory, thereby avoiding damage while maintaining mounting efficiency.
2Adaptability or versatility
If the holding tool is exchanged during mounting to accommodate different lead pitches, then different component types can be mounted, but mounting efficiency is reduced
Solution Approach 1:
The system determines whether a single holding tool can be used for multiple component types by analyzing the lead pitch ranges and the holding tool's clamping capabilities. When a holding tool's trajectory does not intersect with previously-attached components, the system can use that same holding tool for different component types without exchange, thereby improving mounting efficiency while maintaining adaptability to different lead pitches.
Solution Approach 2:
The system performs preliminary calculation of the holding tool's moving trajectory and determines in advance whether the same holding tool can be used for subsequent components. This pre-analysis allows the system to plan mounting sequences that minimize holding tool exchanges, thereby improving efficiency while maintaining the ability to handle different component types.
