Solution Overview

Problem

Existing feeder devices for component mounters face issues with reliably peeling cover tape from carrier tape without damaging components, and require manual notching or pre-peeling of the tape, which is cumbersome and inefficient, especially when switching reels.

Innovation Solution

A tape peeling mechanism with a peeling member that enters the leading end surface of the carrier tape and displaces upwards, allowing it to settle between the carrier tape and cover tape, enabling reliable peeling without manual intervention or notching, and preventing damage to components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a protruding section is positioned higher than the cover tape to ease cutting, then cutting is easier, but the body of the component storage tape goes under the protruding section and components cannot be supplied

Engineering Contradiction:
Improvecutting easeVSAvoidcomponent supply reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The protruding section is designed to be movable in the vertical direction, allowing it to dynamically adjust its position. It moves downward to enter the gap between cover tape and carrier tape, then moves upward to return to its original position, enabling both easy entry and reliable component supply without manual intervention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The protruding section automatically performs the function of entering the gap and returning to its original position through elastic recovery or spring mechanism, eliminating the need for manual notching or pre-peeling operations. The system serves itself by autonomously completing the tape separation initiation process

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the protruding section strikes the carrier tape to separate the tapes, then the cover tape is peeled, but the carrier tape may be ripped and components damaged

Engineering Contradiction:
Improvetape peelingVSAvoidcarrier tape damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A cushioning section is provided at the lower end of the protruding section to absorb impact and prevent damage when the protruding section strikes the carrier tape. This cushioning element allows the protruding section to effectively separate the tapes without causing rips or component damage

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The physical state of the protruding section's lower end is changed by adding a cushioning section, which modifies the interaction characteristics between the protruding section and carrier tape. This parameter change transforms a potentially harmful rigid impact into a controlled, damage-free separation action

Inventive Principle:
Principle #35Parameter changes

3Reliability

If manual notching or pre-peeling is performed to facilitate protruding section entry, then the protruding section enters smoothly, but additional manual work is required each time a reel is exchanged

Engineering Contradiction:
Improveprotruding section entryVSAvoidmanual operation requirement
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protruding section automatically enters the gap between cover tape and carrier tape through its own vertical movement, eliminating the need for manual notching or pre-peeling operations. The system performs the entry function itself, reducing operational complexity and enabling continuous operation without interruptions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The protruding section is pre-positioned and pre-configured to automatically perform the entry action into the tape gap when the reels are exchanged, eliminating the need for subsequent manual intervention. The preliminary design of the movable protruding section ensures smooth entry without additional operations

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention includes a tape peeling mechanism (5) provided with a peeling member (55) configured to enter a leading end surface (8T) in a feeding direction of fed component supply tape (8) made from carrier tape (82) and cover tape (81) so as to peel the cover tape from the carrier tape 82, enabling a component (P) to be supplied from at a component supply position (15), wherein the peeling member is displaced upwards after entering the leading end surface of the carrier tape as the component supply tape is fed. Accordingly, cover tape is reliably peeled without damaging components, and changeover work on the leading end of the component supply tape is not required.
