Component Mounting Control for On-the-Fly Model Data Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting devices face productivity issues due to the need for pre-testing of image processing data validity before starting mounting operations, which delays the commencement of component mounting work.
Innovation Solution
A component mounting device equipped with a control device 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 validity confirmation necessity of model data, allowing for on-the-fly validation of model data during the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If testing is performed to confirm the validity of model data before starting component mounting work, then the reliability of mounting operations is improved, but the productivity of component mounting work deteriorates
Solution Approach 1:
The system performs preliminary validation by storing validity confirmation status in advance. When model data is loaded, the system checks whether validity confirmation is necessary and stores this information in the confirmation-necessity storage section, allowing the mounting operation to proceed without waiting for actual validation testing.
Solution Approach 2:
The error determining section automatically determines whether a processing error has occurred and checks the confirmation-necessity storage section to decide whether validity confirmation is needed. The system serves itself by autonomously managing the validation process without requiring external intervention or pre-testing before mounting operations begin.
2Reliability
If pre-testing of image processing data is performed before mounting operations, then data validity is ensured, but the start time of component mounting work is delayed
Solution Approach 1:
The system performs preliminary preparation by storing the validity confirmation status in the confirmation-necessity storage section when model data is loaded. This preliminary action identifies which data requires validation without actually performing the validation testing, allowing mounting operations to start immediately while validation can proceed in parallel or be skipped for confirmed-valid data.
Solution Approach 2:
The mounting operation continues without interruption by using the pre-stored validity confirmation status. The control device refers to the confirmation-necessity storage section to determine whether to perform validation, allowing the mounting process to maintain continuous operation without stopping for pre-testing, thus eliminating downtime while still ensuring data validity when needed.
3Reliability
If validity confirmation of model data is performed before mounting operations, then processing errors are prevented, but the efficiency of component mounting work is reduced
Solution Approach 1:
The system performs preliminary classification by storing validity confirmation status in the confirmation-necessity storage section. This preliminary action categorizes model data into those requiring validation and those already confirmed, allowing the mounting operation to proceed efficiently by skipping validation for confirmed data while maintaining error prevention for data requiring validation.
Solution Approach 2:
The control device autonomously manages the validation process by referring to the confirmation-necessity storage section. The error determining section automatically determines whether validation is needed based on pre-stored information, eliminating the need for manual pre-testing and allowing the system to self-regulate the balance between error prevention and operational efficiency.

AI summary
In the component mounting device (1), a control device (100) includes a model data storage section (110) for storing model data related to a component (P), an error determining section (120) for determining whether a processing error has occurred, and a confirmation-necessity storage section (130) 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 (110). When it is determined that a processing error has occurred, the control device (100) temporarily suspends the operation of the component transfer device (30) when the model data, related to the target component (P) held by the component transfer device (30), stored in the confirmation-necessity storage section (130) indicates that confirmation is necessary, but continues the operation of the component transfer device (30) when the model data stored in the confirmation-necessity storage section (130) indicates that confirmation is unnecessary.
