Shutter Mechanism for Component Mounting Head Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting apparatuses face safety hazards when the carriage is separated from the base, as the exposed cavity can lead to accidental contact with the moving mounting head, necessitating the shutdown of the mounting head to ensure operator safety.
Innovation Solution
A component mounting apparatus with a shutter mechanism that moves from an open to a closed position when the carriage is separated from the base, preventing accidental access to the mounting head while allowing continuous operation of the mounting head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the carriage is separated from the base to allow operator access, then operator safety is improved, but the mounting head operation must be stopped which reduces productivity
Solution Approach 1:
The cover member is divided into multiple sections: a fixed cover and a movable shutter. This segmentation allows the shutter to independently move between opened and closed positions while the rest of the cover remains stationary, enabling safety control without stopping the entire mounting head operation
Solution Approach 2:
The shutter is designed as a movable component that can dynamically change position between opened and closed states based on carriage attachment status. This dynamic adjustment allows the system to adapt safety measures without compromising continuous production on the other side
2Reliability
If the mounting head operation is stopped when carriage is separated, then operator safety is improved, but production efficiency deteriorates
Solution Approach 1:
Safety control is applied locally only to the side where the carriage is separated. The shutter closes only on the affected side while the mounting head can continue operating on the other side, providing localized safety without global production stoppage
Solution Approach 2:
The shutter acts as an intermediary element between the carriage and the mounting head. It mediates the safety requirement by physically blocking access to the cavity when needed, while allowing the mounting head to continue its operation without direct interference

AI summary
A component mounting apparatus includes a carriage that holds a part feeder for supplying a component in a state of being attached to a base and attaches the part feeder to the base in a state of being coupled to the base; a mounting head that mounts the component to a substrate after the component is taken out of the part feeder held by the carriage coupled to the base through an opening formed between the base and a cover member formed so as to cover an upward side of the base; and a shutter moved from an opened position in which the opening is opened to a closed position in which the opening is closed when the carriage is separated from the base.
