Component Supply Device Cover Mechanism for Tape Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component supply devices using component storage tapes face instability in component delivery due to the lack of a mechanism to prevent components from jumping out of the storage parts after the exposing process, leading to reduced efficiency in supplying components to the extracting position.
Innovation Solution
A component supply device is designed with a tape feeding unit, a tape travel path forming unit, a component exposing unit, and a cover member that covers the component storage parts after exposure, ensuring stable delivery by preventing component jumping through a carefully structured travel path and cover mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cover tape is cut and spread out by the cover tape opening device, then the component exposing process is completed, but the components may jump out of the component storage parts
Solution Approach 1:
The cover member is positioned and ready to cover the component storage parts immediately after the exposing process. This preliminary preparation ensures that as soon as the cover tape is opened and components are exposed, the cover member can instantly cover them to prevent jumping out, thus maintaining both exposing accuracy and component stability.
Solution Approach 2:
The cover member acts as an intermediary element between the exposed components and the external environment. It provides a protective interface that allows the components to be exposed for extraction while preventing them from jumping out, thus resolving the contradiction between exposing accuracy and component stability.
2Device complexity
If no cover member is provided after exposing, then the exposing process is simple, but the stability of component supply is deteriorated
Solution Approach 1:
The component supply device is segmented into distinct functional units: the exposing unit that handles the cover tape opening and the cover member unit that provides protection. This segmentation allows the exposing process to remain simple while adding the necessary coverage function separately, thus maintaining exposing simplicity while improving component supply stability.
Solution Approach 2:
The cover member provides localized protection only to the component storage parts that have been exposed, rather than covering the entire tape. This localized approach maintains the simplicity of the exposing process for areas that need to be accessed while providing stability where needed, thus resolving the contradiction between process simplicity and supply stability.
3Productivity
If the component storage tape is intermittently fed, then the components can be exposed sequentially, but the components may jump out during feeding
Solution Approach 1:
The cover member operates in a periodic manner synchronized with the intermittent feeding of the component storage tape. When the tape stops at each position for component extraction, the cover member covers the exposed components. This periodic operation maintains component position stability during feeding while allowing efficient sequential extraction, thus resolving the contradiction between productivity and position stability.

AI summary
A component supply device supplies components stored in a component storage tape to a component extracting position. The component supply device includes a component exposing unit that performs an exposing process for exposing the components in the component storage tape fed by a tape feeding unit, the component storage tape traveling on a travel path formed from a tape travel path forming unit. The component supply device further includes a cover member that covers at least a part of each component storage part of the component storage tape after the exposing process by the component exposing unit.
