Component Mounting Control for Selective Model Data Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting devices face productivity issues due to the need for pre-testing of image processing data validity, which delays the start of component mounting work and increases costs associated with testing and potential component disposal.
Innovation Solution
A component mounting device with a control system that includes a model data storage section, an error determining section, and a confirmation-necessity storage section, which temporarily suspends or continues the mounting operation based on the necessity of confirming the validity of model data, allowing for on-the-fly validation of data during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If testing is performed to confirm the validity of image processing data before starting component mounting work, then the reliability of mounting operations is improved, but the productivity of component mounting work deteriorates due to the time required for testing
Solution Approach 1:
The system performs preliminary validation by storing validation results in advance for each piece of model data. When the same model data is used again, the pre-stored validation information is retrieved, eliminating the need to repeat testing and allowing immediate mounting operations to proceed.
Solution Approach 2:
The system creates a copy of the validation result and stores it in association with the model data. This copied validation information is then reused for subsequent mounting operations, avoiding redundant testing while maintaining reliability assurance.
2Reliability
If testing is performed to confirm the validity of image processing data, then mounting errors are reduced, but the time required for component mounting work increases
Solution Approach 1:
Validation testing is performed in advance and the results are stored in the storage unit. This preliminary validation ensures mounting accuracy while the stored results enable rapid subsequent operations without repeating the time-consuming testing process.
Solution Approach 2:
The system serves itself by automatically retrieving and utilizing previously stored validation information for subsequent mounting operations, eliminating the need for repeated manual or automated testing and reducing time loss.
3Productivity
If continuous mounting operation is performed without pre-testing, then productivity is improved, but the risk of errors due to invalid model data increases
Solution Approach 1:
The system incorporates feedback through the storage and retrieval of validation results. When model data is used, the system checks for existing validation information, and if found, continues operation with confirmed validity. This feedback mechanism ensures reliability while maintaining continuous operation for productivity.
Solution Approach 2:
The system dynamically adjusts its operation mode based on the availability of stored validation information. When validation data exists, it operates in continuous mode for high productivity; when validation is needed, it performs quick validation before continuing, thus adapting to maintain both productivity and reliability.

AI summary
In the component mounting device, a control device includes a model data storage section for storing model data related to a component, an error determining section for determining whether a processing error has occurred, and a confirmation-necessity storage section for storing whether confirmation of the validity of the model data is necessary when the processing error has occurred in a series of processes performed based on each piece of model data stored in the model data storage section. When it is determined that a processing error has occurred, the control device temporarily suspends the operation of the component transfer device when the model data, related to the target component held by the component transfer device, stored in the confirmation-necessity storage section indicates that confirmation is necessary, but continues the operation of the component transfer device when the model data stored in the confirmation-necessity storage section indicates that confirmation is unnecessary.
