Reel With Separable Flanges For Compact Tape Feeder Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reels for taping electronic component packages occupy excessive space, making it difficult to mount multiple electronic components efficiently due to the need for staggered positioning and increased installation space requirements.
Innovation Solution
A reel design featuring a core with a pair of flanges that include a separating portion, allowing irreversible separation, enabling the reel to be detached from the taping electronic component package and attached to a tape feeder in a compact space, with options for perforations, snap-fit, or friction-reducing features to facilitate easy extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional reels with fixed flanges are used, then the reel structure is simple and strong, but the installation space increases due to staggered positioning requirements
Solution Approach 1:
The reel is divided into a core and a pair of flanges that can be separated from each other. The flanges are detachably connected to the core, allowing the reel to be disassembled into separate components. This segmentation enables the flanges to be positioned independently on the tape feeders without requiring staggered arrangement, thereby reducing installation space while maintaining structural integrity during operation.
Solution Approach 2:
The flanges are designed with detachable connection mechanisms (such as bayonet mounts, screw connections, or friction-fit interfaces) that allow the reel structure to transition from a fixed state during operation to a separable state for installation and maintenance. This dynamic capability enables flexible positioning and reduces the need for staggered arrangement of multiple reels, optimizing space utilization.
2Productivity
If multiple carrier tapes are mounted on a component mounter, then more electronic components can be mounted, but the installation space increases due to reel positioning requirements
Solution Approach 1:
By segmenting the reel into separable flanges and core, multiple reels can be designed with compact footprints that fit closely together on the component mounter. The flanges can be independently positioned to align with tape feeder locations, enabling denser arrangement of multiple carrier tapes without requiring excessive installation space, thus increasing productivity.
3Ease of operation
If the flanges are permanently fixed to the core, then the reel structure is simple, but the reel cannot be easily detached from the taping electronic component package
Solution Approach 1:
The reel is segmented into a core and detachable flanges connected through removable interfaces. This segmentation allows the flanges to be easily separated from the core for reel extraction from the taping electronic component package. The detachable connection mechanisms are designed for quick release while maintaining structural strength during normal operation, achieving ease of operation without excessive complexity.
Solution Approach 2:
The connection between flanges and core is designed to be dynamic rather than permanent, allowing the reel structure to transition between locked and unlocked states. This enables easy extraction and reinstallation of reels while maintaining structural integrity during operation, balancing ease of operation with acceptable structural complexity.

AI summary
A reel for a taping electronic component package with a tape including multiple recesses and electronic components housed in the respective recesses includes a core around which the taping electronic component package is to be wound, a pair of flanges that are located at respective ends of the core and that face each other across the core in an axial direction, and a separating portion that irreversibly separates the flanges.
