Mounting Head Inspection and Remounting for Missing Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inspection devices lack efficient countermeasures for missing components, leading to reduced production efficiency, and existing mounting devices do not consider foreign objects or missing components during the inspection process.
Innovation Solution
A mounting device with a supply section, mounting section, and inspection/imaging section that captures images to detect missing components and controls the mounting process to remount them, integrating inspection and mounting functions to enhance production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foreign object inspection is performed on all boards, then inspection thoroughness is improved, but production efficiency deteriorates due to unnecessary inspections on boards without missing components
Solution Approach 1:
The inspection device performs missing component inspection before foreign object inspection. By first detecting missing components and then selectively performing foreign object inspection only on boards with detected missing components, the system avoids unnecessary inspections on normal boards, thereby improving production efficiency while maintaining inspection thoroughness for problematic cases
2Measurement precision
If operator intervention is used for missing components, then inspection accuracy is improved, but production efficiency deteriorates due to manual operations
Solution Approach 1:
The mounting device is equipped with both inspection functionality and remounting functionality. When a missing component is detected, the system automatically performs remounting operations without requiring operator intervention. This self-service capability maintains inspection accuracy while significantly improving production efficiency by eliminating manual operations
3Reliability
If comprehensive inspection is performed, then product quality is improved, but device complexity increases due to multiple inspection functions
Solution Approach 1:
The mounting device integrates multiple functions including component mounting, missing component inspection, and foreign object inspection into a single system. By making the mounting device universal and capable of performing both mounting and inspection functions, the system improves product quality through comprehensive inspection while avoiding the need for separate dedicated inspection devices, thus not increasing overall device complexity

AI summary
A mounting device of the present disclosure used in a mounting system, includes a supply section configured to hold a component, a mounting section configured to pick up the component from the supply section and perform a mounting process for the component on a mounting target, an inspection/imaging section configured to capture an image of the mounting target, and a control section configured to execute a missing component inspection process of detecting whether a component on the mounting target is missing or not by using a captured image of the mounting target, and, when a component is missing, control the mounting section to pick up the missing component from the supply section and dispose the missing component on the mounting target.
