Feeder ID Detection for Mounting Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting systems, the existing methods require unnecessary and inefficient component checking operations when a parts feeder is temporarily detached and reattached, leading to increased working load and reduced efficiency.
Innovation Solution
A method and device that detect feeder ID information to confirm if the reattached parts feeder is the same as the previously attached one, and calculate the attaching/detaching time, allowing the mounting operation to proceed without a component checking operation if the time is within a given limit, thereby eliminating unnecessary checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If component checking operation is performed every time parts feeder is attached, then reliability of component mounting is improved, but productivity is deteriorated due to unnecessary checks during temporary detachment
Solution Approach 1:
The system dynamically adjusts the component checking operation based on the detected reason for parts feeder attachment. When temporary detachment is detected (within the time threshold), the checking operation is skipped. When permanent replacement is detected (exceeding the time threshold), the checking operation is performed. This dynamic adjustment resolves the contradiction by making the checking process adaptive to actual operational context.
Solution Approach 2:
The system changes the operational parameter (component checking) based on the time parameter. By comparing the elapsed time since detachment with a predetermined threshold, the system determines whether to perform checking or not. This parameter-based decision mechanism allows the system to maintain reliability when needed while improving productivity when unnecessary checks would occur.
2Measurement precision
If component checking operation is performed to verify feeder ID and component kind, then accuracy of component mounting is improved, but working load is increased due to complicated verification procedures
Solution Approach 1:
The system extracts the component checking operation from the mandatory attachment procedure and makes it conditional. By detecting the attachment reason and comparing it with temporary detachment criteria, the system removes unnecessary checking steps while retaining essential verification only when needed. This extraction principle reduces working load without compromising identification accuracy.
Solution Approach 2:
The system performs automatic detection of feeder ID information and automatic comparison with stored data to determine attachment reason. This self-service mechanism eliminates the need for manual verification by operators in temporary detachment cases, reducing working load while maintaining identification accuracy through automated processes.

AI summary
A component mounting method includes: detecting feeder ID information of a parts feeder, which individually specifies a parts feeder, after a second parts feeder is attached to an attaching position of the feeder base having a feeder address, and confirming whether the second parts feeder is the same as a first parts feeder which was attached to and then detached from the attaching position; and calculating an attaching/detaching time from detachment of the first parts feeder to attachment of the second parts feeder if it is confirmed that the second parts feeder is the same as the first parts feeder. If the calculated attaching/detaching time is a given time or shorter, the mounting work is performed without performing a component checking operation which determines whether a kind of an electronic component accommodated in the second parts feeder is proper.
