Tape Feeder Cover Tape Winding With Shared Torque Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tape feeders require a large space to collect separated top tapes, leading to an increase in size.
Innovation Solution
A tape feeder design that includes a pair of rotating members to separate and collect cover tape from a carrier tape using a shared driving source, with a drum member to wind the cover tape, and a distribution mechanism to distribute torque to these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large space is provided for collecting separated top tapes, then all top tapes can be properly collected, but the size of the tape feeder increases
Solution Approach 1:
The patent combines the cover tape separation function and the collection function into a single integrated mechanism. The rotating members both separate the cover tape from the carrier tape and simultaneously wind it onto the drum member, eliminating the need for separate collection space and reducing overall feeder size while maintaining complete collection capability
2Ease of operation
If separate driving sources are used for separation mechanism and collection mechanism, then each function can be independently controlled, but the device complexity and size increase
Solution Approach 1:
The patent employs a single driving motor that performs multiple functions through a distribution mechanism. The motor drives both the separation rotating members and the collection drum member, allowing one power source to control both separation and collection operations, thereby reducing device complexity while maintaining operational control
Solution Approach 2:
The patent introduces a torque distribution mechanism as an intermediary between the single driving motor and the multiple driven components. This distribution mechanism enables the motor to effectively control both the separation rotating members and the collection drum member, resolving the conflict between using a single driving source and maintaining independent control of different functions

AI summary
A tape feeder feeds a component supply tape including a cover tape adhered on a carrier tape accommodating multiple components to a predetermined supply position, and separates the cover tape from the carrier tape in front of the supply position to expose a component on the carrier tape. The tape feeder includes a pair of rotating members configured to separate the cover tape from the carrier tape by pinching and drawing the cover tape; a drum member configured to rotate and wind the cover tape drawn by the pair of rotating members; a driving motor; and a distribution mechanism configured to distribute a rotational driving force from the driving motor to one rotating member of the pair of rotating members and the drum member.
