Electronic Component Mounting System Skipping Dummy Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic component mounting systems experience line stops and manual restarts due to the detection of dummy boards or unreadable ID information, leading to inefficiencies and reduced operating rates.
Innovation Solution
An electronic component mounting system with an identification information read device, wired or wireless communication means, and mounting requirement/nonrequirement determination means that reads and transmits identification information to control units, allowing for automated determination of mounting operations and eliminating unnecessary line stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the dummy board is detected and the line is stopped to take out the dummy board, then the type change can be performed, but the operating rate deteriorates due to line stop and manual restart operations
Solution Approach 1:
The control unit determines in advance whether a board is a dummy board by reading its identification information before the board reaches the mounting position. This preliminary identification allows the system to prepare for type change operations without stopping the conveyance line, thereby maintaining high operating rate while enabling smooth type changes.
Solution Approach 2:
The system automatically identifies dummy boards through reading identification information and autonomously determines whether mounting operations should be skipped. This self-service capability eliminates the need for manual intervention to detect and remove dummy boards, allowing continuous operation without line stops while still performing necessary type changes.
2Reliability
If the line is stopped to handle boards with unreadable ID information, then traceability can be ensured, but the operating rate deteriorates due to repeated line stops and restarts
Solution Approach 1:
The control unit reads and verifies identification information in advance at the uppermost stream of the conveyance path. When unreadable ID information is detected, the system determines ahead of time whether the board should be skipped, allowing continuous conveyance without stopping the line while still maintaining traceability through automated determination.
Solution Approach 2:
The system automatically handles boards with unreadable ID information by using the mounting requirement/nonrequirement determination means to decide whether to skip mounting operations. This self-service mechanism eliminates the need for manual intervention and line stops, maintaining both traceability and high operating rate.
3Adaptability or versatility
If manual operations are performed for every dummy board removal and line restart, then proper type change can be executed, but the device complexity and operation difficulty increase
Solution Approach 1:
The control unit automatically performs all operations related to dummy board identification and type change execution. The system reads identification information, determines whether boards are dummy boards, and automatically adjusts mounting operations without requiring any manual intervention. This eliminates complex manual operations while ensuring proper type change execution.
Solution Approach 2:
The system continuously monitors identification information from boards and provides feedback to the control unit, which automatically adjusts the mounting program based on the detected board type. This closed-loop feedback mechanism ensures proper type change execution while eliminating the need for manual operations.

AI summary
In an electronic component mounting system constituted by interconnecting a plurality of mounting apparatuses, a board ID code attached by digital data to the board is read in a board supply apparatus located in the uppermost stream and transmitted to the mounting apparatuses on the downstream side via communication means. By comparing the transmitted board ID code with mounting nonrequirement board code data (defective board code, read error code, dummy board code, etc.) preparatorily stored in a storage section in the mounting apparatus, it is determined whether or not execution of mounting operation of the board is required, and the board determined to be not required to be subjected to mounting is unloaded to the downstream side without carrying out mounting works and without line stop.
