Mounting Device Position Correction for Fine Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting devices face challenges in achieving sufficient accuracy when handling finer components, and existing configurations do not adequately ensure mounting accuracy or reduce processing time.
Innovation Solution
A mounting device that sets correction values for each position where the mounting head operates, using multiple correction values to improve accuracy by storing and applying specific values for different positions, elevations, and regions, allowing for precise position correction during the mounting process.

Engineering Contradiction Analysis
1Manufacturing precision
If a single correction value is used for all positions, then the device complexity is reduced, but the mounting accuracy deteriorates
Solution Approach 1:
The patent applies local quality by storing and applying different correction values for different work positions of the mounting head. Instead of using a single correction value for the entire work area, the system divides the work space into multiple position regions and stores position-specific correction values (first correction value for first position, second correction value for second position, etc.). This allows each region to receive the appropriate correction tailored to its specific spatial characteristics, thereby improving mounting accuracy without requiring a completely complex redesign of the correction system.
Solution Approach 2:
The correction value management system is segmented into multiple independent correction value storage units, with each unit corresponding to a specific work position. The control section selectively retrieves and applies the appropriate correction value based on the current work position, effectively segmenting the correction process into position-specific operations. This segmentation approach balances accuracy improvement with manageable system complexity.
2Manufacturing precision
If multiple correction values are stored for different positions, then the mounting accuracy is improved, but the storage section capacity and device complexity increase
Solution Approach 1:
The system stores multiple correction values corresponding to different work positions in the storage section, with each correction value tailored to specific spatial characteristics. The control section retrieves and applies the appropriate correction value based on the current work position, ensuring that each position receives the optimized correction parameters needed for high-accuracy mounting of finer components.
3Manufacturing precision
If various configurations are added to the mounting member to improve accuracy, then the mounting accuracy is improved, but the processing time increases
Solution Approach 1:
The correction values are determined and stored in advance through preliminary calibration processes. During actual mounting operations, the control section simply retrieves and applies the pre-computed correction values for the current work position, rather than performing complex real-time calculations. This preliminary action approach enables high-accuracy mounting of finer components while minimizing processing time during production.

AI summary
A mounting device for executing a mounting process of mounting a component on a board includes: a mounting head that includes at least one pickup section for picking up the component and moves the picked up component; a storage section configured to store at least a first correction value determined at a first position on XYZ axes on which the mounting head works and a second correction value determined at a second position different from the first position; and a control section configured to execute the mounting process by using the first correction value and/or the second correction value stored in the storage section.
