Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting methods face inefficiencies when holding leads of lead components with a holding tool, as they may damage previously attached components and require frequent 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 of holding tools by analyzing lead component shapes, mounting data, and tool capabilities to avoid interference with previously attached components, allowing for efficient mounting of lead components on a board without tool exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a holding tool is used to hold leads of a lead component and mount it on a board, then the component can be installed, but the holding tool may come in contact with previously-attached components and damage them
Solution Approach 1:
The system performs preliminary analysis of the holding tool's moving trajectory and previously-attached component positions before mounting. The mounting order determination section determines an optimal mounting sequence that prevents interference, and the pusher position adjustment section pre-adjusts the pusher position based on predicted holding tool movement, ensuring the holding tool does not contact previously-attached components
Solution Approach 2:
The system uses detection information about previously-attached components to feedback and adjust the mounting process. The detection section detects the positions and types of previously-attached components, and this information is used by the mounting order determination section and pusher position adjustment section to dynamically adjust the mounting sequence and pusher positions to avoid damage
2Productivity
If the holding tool is moved 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 come in contact with previously-attached components
Solution Approach 1:
The system pre-determines the mounting order of lead components based on the positions of previously-attached components and the moving directions of holding tools. This preliminary planning ensures that components are mounted in a sequence that prevents the holding tool from contacting previously-attached components during the pressing operation
Solution Approach 2:
The system dynamically adjusts the pusher position based on the type of previously-attached component and the moving direction of the holding tool. This dynamic adjustment allows the pusher to be positioned optimally for each mounting operation, enabling the holding tool to move freely without contacting previously-attached components
3Adaptability or versatility
If the holding tool is exchanged during mounting to accommodate different lead pitches, then different lead pitches can be handled, but the mounting efficiency is lowered
Solution Approach 1:
The system uses a single holding tool that can handle multiple lead pitches by adjusting its clamping position. The holding tool data storage section stores clamping position data for different lead pitches, and the holding tool moves the clamping position according to the lead pitch of the component to be mounted, eliminating the need to exchange tools while maintaining versatility
Solution Approach 2:
The system changes the clamping position parameter of the holding tool according to the lead pitch of different components. Instead of exchanging tools, the system adjusts the clamping position to match the required lead pitch, maintaining adaptability while improving mounting efficiency by avoiding tool exchange
