Embossed Carrier Tape Feeder for Non-Collapsing Cover Tape Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auto-loading feeders risk damaging electronic components when using embossed carrier tapes due to the collapse of the component storage section under strong biasing forces, as the pressing mechanism pushes against the embossed section, causing components to be ejected and potentially damaged during cover tape separation.
Innovation Solution
A feeder design with a recessed groove in the tape conveyance path that allows the embossed carrier tape to be inserted and pressed against the tape guide without directly pressing the component storage section, using a pressing device positioned on both sides of the embossed carrier tape's flange sections to ensure accurate abutment with the tape separating device, preventing the collapse of the component storage section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a strong biasing force is applied to the carrier tape to ensure accurate separation of the cover tape, then the separation accuracy is improved, but the component storage section collapses and electronic components are damaged
Solution Approach 1:
The pressing device is divided into multiple pressing members that are distributed at different positions. Specifically, pressing members are arranged to press the flange sections and the separating member presses the cover tape, distributing the pressing force across different areas rather than concentrating it on the component storage section, thus preventing collapse while ensuring separation accuracy
Solution Approach 2:
Different parts of the carrier tape receive different pressing forces from the pressing device. The flange sections are pressed by dedicated pressing members, the cover tape is pressed by the separating member, while the component storage section is explicitly excluded from pressing, creating localized quality differences in force application that protect components while enabling separation
2Reliability
If the pressing member presses the carrier tape strongly to bring it into abutment with the separating member, then the separation reliability is improved, but the embossed component storage section is collapsed
Solution Approach 1:
The pressing device structure segments the pressing function into multiple independent pressing members positioned at specific locations. This segmentation allows the flange pressing members and the separating member to work independently, ensuring that pressing force is applied only where needed for separation while preserving the storage section shape
Solution Approach 2:
The flange sections act as intermediary elements that transmit the pressing force from the pressing members to the carrier tape without directly pressing the component storage section. This intermediary mechanism allows the carrier tape to be brought into abutment with the separating member reliably while the storage section shape remains intact

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for the accurate separation of the cover tape without collapsing the embossed carrier tape's component storage section, ensuring electronic components are not damaged and can be picked up reliably, maintaining the integrity of the embossed carrier tape during the separation process.
Implementation Method 1
a pressing device disposed in the recessed groove of the tape conveyance path and configured to press the embossed carrier tape in a direction in which the embossed carrier tape is brought into abutment with the tape guide
Implementation Method 2
a lower surface of carrier tape 90 conveyed on tape conveyance path 2 provided in feeder main body 1 is pressed towards separating member 6 provided on tape guide 5 by means of pressing member 4 biased by spring 3

AI summary
A feeder includes a feeder main body, a tape guide provided in feeder main body, a tape separating device to separate cover tape covering component storage sections, a tape conveyance path between the feeder main body and the tape guide and having recessed groove through which the component storage sections of the embossed carrier tape can be inserted, and a pressing device disposed in the recessed groove of the tape conveyance path to press the embossed carrier tape in a direction in which the embossed carrier tape is brought into abutment with the tape guide. The pressing device is positioned at both sides of the component storage sections in a width direction in of the recessed groove and presses flange sections of the embossed carrier tape without pressing the component storage sections.
