Cutting Blade Cleaning Mechanism for Sheet Sticking Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sheet sticking apparatus faces issues with cutting failure due to dust from soft resin sheets adhering to the cutting blade, leading to reduced sharpness and incomplete cuts.
Innovation Solution
Incorporating a cleaning part within the cutting unit that moves along the trajectory of the cutting blade, equipped with scrapers or brushes to remove adhering dust and maintain blade sharpness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cutting blade is used to cut the sheet, then cutting function is achieved, but dust from soft resin sheet adheres to the cutting blade causing reduced sharpness and cutting failure
Solution Approach 1:
The harmful dust particles are extracted from the cutting blade surface by the cleaning part, which removes adhering things from the cutting blade trajectory. This separation of the cutting function from the contamination source maintains blade sharpness and prevents cutting failure.
Solution Approach 2:
The cleaning part acts as an intermediary element between the cutting blade and the dust particles. It intercepts and removes adhering things from the blade surface, preventing direct contact between dust and the cutting edge, thus maintaining cutting performance.
2Productivity
If the cutting blade cuts the sheet repeatedly, then productivity is improved, but blade sharpness decreases due to dust accumulation
Solution Approach 1:
The cleaning part performs preliminary cleaning action during the cutting process by removing adhering things from the blade surface in advance. This prevents dust accumulation that would otherwise degrade blade sharpness and cut quality, allowing continuous high-precision cutting operations.
Solution Approach 2:
The cleaning mechanism enables continuous cutting operations by maintaining blade sharpness throughout the process. The cleaning part continuously removes adhering things from the blade trajectory, ensuring consistent cutting performance without interruption for blade replacement or sharpening.

AI summary
A sheet sticking apparatus includes a sticking unit that sticks a sheet to a workpiece held by a chuck table and a cutting unit that cuts the stuck sheet. The cutting unit includes a cutting blade that cuts the sheet, a movement unit that raises and lowers the cutting blade from and toward the chuck table or moves the cutting blade along the outer circumference of the workpiece, and a cleaning part that removes adhering things of the cutting blade. The cleaning part is disposed on the trajectory of the cutting blade that moves by the movement unit and executes cleaning by coming into contact with the cutting blade that moves.
