Solution Overview
Problem
Conventional methods for detaching protective seals with strong adhesive force require complex device configurations or are cumbersome, while simpler methods struggle with strong adhesion.
Innovation Solution
A method and device using a rotating roller with adhesiveness to press and rotate an adhesive tape piece onto a protective seal, allowing easy detachment by adhering the tape to the seal and peeling it from the workpiece surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods (hollow pipe vacuum adsorption, adhesive tape with sensors, winding means) are used to detach protective seals with strong adhesive force, then the protective seal can be detached, but the device configuration becomes complex and operations become cumbersome
Solution Approach 1:
The detachment device is segmented into three functional units: a supply unit for providing adhesive tape, a pressing unit for pressing the adhesive tape onto the protective seal, and a winding unit for winding the adhesive tape. This segmentation allows each unit to perform its specific function efficiently while keeping the overall device structure simple and manageable
Solution Approach 2:
The adhesive tape automatically adheres to the protective seal when pressed, and the winding unit automatically winds the tape as the detached seal is pulled out. The system uses the adhesive properties of the tape itself to achieve detachment without requiring additional complex mechanisms, making the device self-sufficient and operationally simple
2Device complexity
If simpler detachment methods are used, then device complexity is reduced, but the ability to handle protective seals with strong adhesive force is insufficient
Solution Approach 1:
The supply unit prepares and supplies adhesive tape in advance before the detachment process begins. The pressing unit pre-presses the adhesive tape onto the protective seal to ensure proper adhesion before the winding action starts. These preliminary actions ensure that when the winding unit operates, the adhesive tape is already properly positioned and adhered, guaranteeing reliable detachment even from seals with strong adhesive force
Solution Approach 2:
Adhesive tape serves as an intermediary medium between the detachment device and the protective seal. Instead of the device directly pulling the seal (which would require great force and complex mechanisms), the adhesive tape mediates the detachment process by adhering to the seal and being wound onto it, converting the detachment action into a manageable winding operation

AI summary
A protective seal detachment method capable of easily detaching a protective seal having strong adhesive force by using a simpler device, and a detachment device used in the method are provided. The protective seal detachment method is a method for detaching a protective seal from a protected workpiece in which a surface of a workpiece main body is protected with the protective seal, and includes: a first process in which an adhesive tape piece having an adhesive surface is pressed by a rotating roller to hold the adhesive tape piece on a roll surface of the rotating roller with the adhesive surface facing outward; and a second process in which the rotating roller holding the adhesive tape piece is pressed against one end of the protective seal on the protected workpiece to adhere to the adhesive surface of the adhesive tape piece and is rotated in an opposite direction toward the other end of the protective seal to peel the protective seal from the surface of the workpiece main body, and the detachment device includes a rotatable rotating roller having a roll surface with adhesiveness and a rotation regulating unit configured to regulate rotation of the rotating roller.
