Tape Feeder Guide Section With Segmented Upper And Lower Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape feeder configurations require complex operations for accurately aligning carrier tapes with tape guides due to the integration of separating and positioning mechanisms, which can lead to interference issues.
Innovation Solution
A tape feeder design with a guide section that includes a lower member for guiding the carrier tape's lower surface, an upper member for guiding the width direction and pressing the carrier tape from above, and a cover tape separating mechanism that exposes components by separating the cover tape from the base tape, ensuring non-interference positions for the positioning and cover tape separating mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separating mechanism and positioning mechanism are assembled in one tape guide, then the tape mounting workability is improved, but the mechanisms may interfere with each other and make accurate alignment difficult
Solution Approach 1:
The tape guide is divided into an upper member and a lower member that can be detached from each other. The positioning mechanism is integrated into the lower member, while the separating mechanism is integrated into the upper member. This segmentation allows the mechanisms to be assembled in one tape guide without interfering with each other, as they are placed in spatially separated locations within the divided structure.
2Reliability
If the carrier tape is set on the body portion by pressing from above, then the carrier tape can be securely positioned, but the operation becomes complicated and time-consuming
Solution Approach 1:
The positioning mechanism is pre-assembled into the lower member of the tape guide, with positioning protrusions and positioning grooves already in place. When the upper member is detached and reassembled, the carrier tape is automatically positioned by these pre-positioned features without requiring manual pressing or complex alignment operations, thus reducing mounting time while maintaining positioning accuracy.
3Ease of operation
If the separating mechanism is provided in the tape guide, then the cover tape separation is facilitated, but the mechanism occupies space that may interfere with the positioning mechanism
Solution Approach 1:
The tape guide is divided into vertical layers: the lower member contains the positioning mechanism, while the upper member contains the separating mechanism. This vertical dimensional separation allows both mechanisms to coexist in the same tape guide without spatial interference, with each mechanism operating in its own designated layer or zone.

AI summary
A positioning mechanism, which determines the relative position of a carrier tape 15 in a tape feed direction by fitting alignment pins 37 to feed holes 15d in a lower member 31, and a cover tape separating mechanism 50, which is provided on an upper member 32 and exposes electronic components 16 stored in component pockets 15b by separating a cover tape 15e from a base tape 15, are provided at non-interference positions that do not interfere with each other when the upper member 32 is closed to the lower member 31. Accordingly, when the cover tape 15e is separated from the carrier tape 15, the carrier tape 15 is aligned with the guide section 30.
