Component Mounter Cover for Tape Rewinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounters face difficulties in rewinding carrier tapes in reverse direction due to the presence of covers, which can inhibit the rewinding operation, potentially damaging the tape or complicating the setup change process.
Innovation Solution
A component mounter with a cover that can be switched between a closed and open state, allowing the carrier tape to be rewound smoothly in reverse direction by widening the return path when necessary, while maintaining safety and operational functions when not rewinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is provided to ensure safety of the tape feeder during operation, then safety is improved, but the rewinding operation of the carrier tape is inhibited and may cause damage or complicate setup change work
Solution Approach 1:
The cover is designed to be movable between a closed state during normal operation and an open state during rewinding. This dynamic configuration allows the cover to provide safety protection when needed while being opened to enable smooth rewinding of the carrier tape in reverse direction without inhibition or damage
2Reliability
If the cover remains closed during normal operation to maintain safety function, then safety is ensured, but the carrier tape cannot be rewound in reverse direction smoothly
Solution Approach 1:
The cover transitions from a static closed position to an open position during setup change operations. This dynamic adjustment enables the operator to rewind the carrier tape smoothly without the cover interfering, thereby improving setup change efficiency while maintaining safety during normal operation
Solution Approach 2:
The cover is opened before the rewinding operation begins, preparing the path for the carrier tape to return smoothly. This preliminary action prevents potential damage to the tape and simplifies the setup change process by eliminating obstacles before they occur

AI summary
The component mounter includes a base including a table attachment section, a feeder table mounted with a tape feeder configured to feed a carrier tape that accommodates multiple components and supply the components to a predetermined supply position, the feeder table being attached to the table attachment section, and a cover provided on the feeder table so as to be changeable between a closed state in which an upper portion of the tape feeder excluding the supply position is covered and an open state in which the upper portion is open.
