Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing taping apparatuses face challenges in increasing the speed of component insertion and reducing the size of the apparatus while ensuring components are properly oriented and collectively inserted into a carrier tape, particularly for substantially rectangular cuboid components like capacitors, inductors, and varistors, due to difficulties in component conveyance and orientation control.
Innovation Solution
A taping apparatus with a rotatable component conveyance disk that has component transport units with grooves, a disk support unit for inclined rotation, a component supply unit for bulk component storage, and a tape guide unit for synchronized carrier tape movement, allowing for simultaneous insertion of multiple components into the carrier tape, with component transport grooves designed to accommodate the components' dimensions and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of supply units are used to provide components into holding holes arranged in the radial direction, then component provision reliability is improved, but the apparatus becomes larger
Solution Approach 1:
A single supply unit is designed to serve multiple holding holes arranged in the radial direction through the rotational movement of the conveyance table. The supply unit can provide components to different radial positions as the table rotates, eliminating the need for multiple separate supply units and reducing apparatus size while maintaining reliable component provision to all holes
Solution Approach 2:
The conveyance table is designed to rotate, transforming a static multi-unit configuration into a dynamic single-unit system. The rotational movement allows one supply unit to sequentially access multiple radial positions, providing components to different holding holes at different times during the rotation cycle, thus achieving the function of multiple supply units with a single unit
2Reliability
If a discharge unit is added to house components into carrier tape recesses, then component insertion completeness is improved, but the apparatus becomes larger and more complex
Solution Approach 1:
The discharge function is merged with the existing conveyance table and holding holes. The holding holes serve dual purposes: receiving components from the supply unit during rotation and subsequently discharging them into the carrier tape recesses. This integration eliminates the need for a separate discharge unit, reducing apparatus complexity while ensuring complete component insertion
Solution Approach 2:
The conveyance table and holding holes are designed to perform multiple functions: component reception, radial conveyance, and discharge into the carrier tape. By making these components multi-functional, the patent avoids adding dedicated discharge mechanisms, thereby reducing overall device complexity while maintaining complete component insertion capability
3Manufacturing precision
If the component conveyance disk rotates horizontally, then component orientation control is improved, but the apparatus size increases
Solution Approach 1:
The patent transitions from horizontal rotation to vertical rotation of the conveyance table. By changing the rotation axis from horizontal to vertical, the apparatus achieves compact footprint while maintaining orientation control capability. The vertical rotation allows the table to present different radial positions to the supply unit and carrier tape at different angles during the rotation cycle, preserving precision without increasing horizontal space
4Manufacturing precision
If components are inserted one at a time, then orientation precision is maintained, but insertion speed decreases
Solution Approach 1:
Multiple components are pre-positioned in the holding holes arranged in the radial direction before the insertion process begins. As the conveyance table rotates, multiple components are simultaneously presented to their respective discharge positions, enabling parallel insertion into the carrier tape. This preliminary arrangement of multiple components allows batch insertion while maintaining orientation precision through the controlled rotational positioning

AI summary
A component conveyance disk of a taping apparatus has a plurality of component transport units at an equiangular interval. Each component transport unit is formed of three component transport grooves in a peripheral portion of the component conveyance disk. Width direction centerlines of the respective component transport grooves are parallel to each other, with a portion thereof in a direction along the width direction centerlines opening toward a component storage chamber. Dimensions along the width direction centerlines of the opened portion of the respective component transport grooves are shorter than a length of the component. In addition, the respective component transport grooves have component guides that guide the components into the respective component transport grooves.
