Component Reception Order Optimization for Mounting Head Movement Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic circuit component mounting machines face inefficiencies in mounting operations due to the need for frequent movement of the mounting device between feeders and the circuit-substrate conveying device, which increases the time required for the mounting process.
Innovation Solution
The method involves determining the reception order of electronic circuit components using a component reception order determining device, minimizing the number of times the head main body moves between the circuit-substrate conveying device and the mounting-machine-main-body-side feeders, and using a system that includes multiple component holding tools to selectively receive and mount components on the circuit substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mounting device frequently moves between feeders and circuit-substrate conveying device, then multiple component types can be mounted, but the mounting time increases and efficiency decreases
Solution Approach 1:
The system pre-determines the reception order of components by the component holding tools before actual mounting. This preliminary planning of the reception sequence allows the mounting device to minimize unnecessary movements between feeders and the substrate conveying device, thereby reducing mounting time while maintaining the capability to handle multiple component types.
Solution Approach 2:
The system dynamically optimizes the reception order based on the specific mounting task requirements. By adaptively determining the sequence in which component holding tools receive components, the system balances the need to mount multiple component types with the goal of minimizing movement time, thus resolving the contradiction between versatility and time efficiency.
2Productivity
If the head main body moves frequently between circuit-substrate conveying device and feeders, then all components can be supplied, but operation efficiency decreases
Solution Approach 1:
The reception order is determined in advance by the component reception order determining device, which plans the sequence of component supply before the actual mounting process. This preliminary determination allows the head main body to move efficiently between the circuit-substrate conveying device and feeders without frequent unnecessary movements, thereby improving operation efficiency while ensuring all required components are supplied.
3Productivity
If component reception order is not optimized, then mounting process is simple, but mounting efficiency is low
Solution Approach 1:
The component reception order determining device automatically determines the optimal reception sequence without requiring complex external control or manual intervention. The system serves itself by internally optimizing the reception order based on the mounting task requirements, thereby improving mounting efficiency while keeping the control mechanism relatively simple and self-contained.

AI summary
A mounting method performed by an electronic circuit component mounting machine that includes a tape feeder (48) which is mounting-machine-main-body-side feeder held by a mounting machine main body, and a bulk feeder (90) which is head-side feeder moved to any position on a movement plane covering a circuit-substrate conveying and holding device and the mounting-machine-main-body-side feeder is improved. A reception order is determined, so as to reduce the number of times a mounting head (56b) moves between the circuit-substrate conveying and holding device and the mounting-machine-main-body-side feeder and the receiving of first type components (150) supplied from the tape feeder (48) and the receiving of second type components (152) supplied from the bulk feeder (90) are respectively performed together as a batch (S2 to S6).
