Shared Imaging System for Head Inspection in Component Mounting Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Component mounting devices require a complex configuration to inspect both component holding tools and dispensing tools, increasing the number of members and complicating the inspection process.
Innovation Solution
A component mounting device with a head holding mechanism that exchanges between mounting and dispensing heads, using a single imaging system to acquire data from both tools, allowing for simplified inspection of component holding and dispensing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate imaging mechanisms are provided for component holding tool and dispensing tool inspection, then inspection coverage is improved, but device complexity increases
Solution Approach 1:
The imaging mechanism is designed to serve multiple functions by inspecting both the component holding tool and the dispensing tool using the same hardware. The imaging mechanism captures images of the component holding tool during component pickup operations and captures images of the dispensing tool during material dispensing operations, eliminating the need for separate imaging systems for each tool type.
Solution Approach 2:
The patent merges the imaging functions for component holding tool inspection and dispensing tool inspection into a single integrated imaging mechanism. This consolidation reduces the total number of imaging devices required in the system while maintaining comprehensive inspection capabilities for both tool types.
2Measurement precision
If multiple imaging mechanisms are provided for different tool inspections, then inspection precision is improved, but quantity of members increases
Solution Approach 1:
The single imaging mechanism is designed to inspect both tool types with sufficient precision by adapting its imaging parameters and positioning for each specific inspection task. The same imaging device achieves adequate measurement precision for component holding tool inspection and dispensing tool inspection without requiring multiple specialized imaging systems.
3Device complexity
If a shared imaging system is used for both tool inspections, then device complexity is reduced, but inspection versatility may be compromised
Solution Approach 1:
The imaging mechanism is designed with universal inspection capabilities that can handle both component holding tool and dispensing tool inspections. The system maintains versatility by being able to inspect different tool types and perform various inspection tasks (component pickup inspection, component mounting inspection, dispensing inspection) using the same imaging hardware, thereby avoiding device complexity while preserving inspection versatility.

AI summary
In a component mounting device, a head held by a head holding section is capable of being automatically exchanged from one of a pickup head attached to which is suction nozzle 13 that is capable of holding and releasing component, and a dispensing head attached to which is a dispensing tool capable of dispensing adhesive from a dispensing outlet, to the other of the heads. Also, when the pickup head is held on the head holding body, a nozzle camera images suction nozzles 13 at nozzle positions 13a to 13c attached to the pickup head from the side using optical system unit 80 and acquires suction nozzle image data. When the dispensing head is held on the head holding body, the nozzle camera images a dispensing nozzle positioned at the center axis of the head holding body from the side using optical system unit 80 and acquires dispensing nozzle image data. Then, component related inspection is performed based on the suction nozzle image data and dispensing related inspection is performed based on the dispensing nozzle image data.
