Component Mounting Calibration Timestamps for Position Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting device faces complexity in setting correction values, as they need to be changed based on scenes defined for each predetermined time, which can lead to defects in mounting positions during device calibration and production program updates.
Innovation Solution
The proposed solution involves a component mounting device with a storage section that associates correction values with the latest date and time information of calibration or production program updates, ensuring that only the relevant correction values are used for mounting, thereby simplifying the processing and preventing defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If correction values are changed for each scene at predetermined time intervals, then quality stability is improved, but the setting process becomes complicated
Solution Approach 1:
The patent changes the management parameter from 'scene-based time intervals' to 'calibration-based association'. Correction values are now linked to calibration execution dates and times, allowing automatic selection based on the latest calibration state rather than predefined scene intervals, thus simplifying the setting process while maintaining quality stability
Solution Approach 2:
The system performs preliminary calibration before production and automatically associates correction values with the calibration execution date and time. This preliminary action ensures that the correct correction values are ready and automatically selected before mounting begins, eliminating the need for complex scene-based setting adjustments
2Device complexity
If correction values are continuously used across calibration updates, then processing is simplified, but mounting position defects may occur
Solution Approach 1:
The system implements feedback by storing the calibration execution date and time, then using this information to automatically determine whether to apply correction values. The mounting position correction section checks the calibration timestamp and only applies correction values when they correspond to the latest calibration state, ensuring precision while keeping processing simple
Solution Approach 2:
The system dynamically adjusts correction value application based on the calibration execution date and time. Rather than statically continuously applying or not applying correction values, the system adapts its behavior based on the current calibration state, automatically selecting the appropriate correction values for the current production context
3Adaptability or versatility
If correction values are updated with each production program change, then adaptability is improved, but the risk of using incorrect correction values increases
Solution Approach 1:
The patent introduces an intermediary mechanism: the calibration execution date and time serves as a mediator between the production program and correction values. This intermediary timestamp verifies whether correction values should be applied, ensuring that adaptability to production program changes is maintained while preventing incorrect correction value application through automatic timestamp comparison

AI summary
A component mounting device that performs mounting processing for mounting a component on a board based on a production program, includes: a storage section configured to store information; a setting section configured to set a correction value related to a mounting position of the component included in the production program; a storage control section configured to make the storage section store date and time information on which calibration related to the mounting processing is executed when the calibration is executed, and to make the storage section store the correction value in association with latest date and time information of the calibration when the correction value is set; and a correction section configured to perform a correction related to the mounting position using the correction value corresponding to the latest date and time information of the calibration without using the correction value not corresponding to the latest date and time information.
