Modular Tape Feeder for Component Mounters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounters face limitations in versatility as they are not adequately equipped to handle multiple tape supply modes, requiring multiple feeders with different functions and complicating reel exchange and component supply processes.
Innovation Solution
A component supply device is designed with a modular configuration, featuring a detachable tape feed unit and tape supply unit, allowing for the selection and attachment of different tape supply modes, such as splicing and auto-loading systems, to support various tape feeding mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single integrated feeder is used to supply components from carrier tape, then the structure is simple, but the device cannot support different tape supply modes (splicing, auto-loading) and lacks versatility
Solution Approach 1:
The feeder is divided into two independent units: a tape feed unit (first unit) that performs pitch feeding, and a tape supply unit (second unit) that supplies carrier tape from reels. These units can be detached and reconfigured to support different supply modes such as splicing or auto-loading, thereby improving versatility without permanently increasing complexity.
Solution Approach 2:
The tape feed unit is designed with a universal interface that can accommodate different types of tape supply units. This allows the same feed unit to work with multiple supply modes (splicing, auto-loading, manual feeding) by simply changing the attached supply unit, achieving multi-functionality while maintaining a simple base structure.
2Adaptability or versatility
If multiple feeders with different functions are used to handle various tape supply modes, then each feeder can be optimized for its specific function, but the overall device complexity increases and reel exchange becomes more complicated
Solution Approach 1:
Instead of using multiple dedicated feeders, the invention uses a single universal tape feed unit that can interface with different tape supply units. This allows one feeder structure to perform multiple functions (splicing, auto-loading, manual feeding) by changing the attached supply unit, thereby reducing the total number of feeders needed while maintaining versatility.
Solution Approach 2:
The feeder system is segmented into a common feed unit and interchangeable supply units. This segmentation allows the feed unit to remain simple and optimized for its core function, while the supply units can be changed to match different supply modes, avoiding the need for multiple complex integrated feeders.
3Ease of operation
If the tape supply unit and tape feed unit are integrated into a single structure, then the structure is simple, but reel exchange and cover tape collection cannot be performed separately
Solution Approach 1:
The feeder is segmented into a tape supply unit and a tape feed unit that are detachably connected. This allows the supply unit (handling reel exchange and cover tape collection) to be separated from the feed unit (handling pitch feeding), enabling independent operation and maintenance of each unit while maintaining a relatively simple overall structure.
Solution Approach 2:
The connection between the supply unit and feed unit is designed to be dynamic (detachable rather than fixed), allowing the configuration to change based on operational needs. This dynamic separability enables easy reel exchange and cover tape collection without requiring disassembly of the entire feeder, balancing ease of operation with structural simplicity.
