Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing in-line deposition apparatus for cutting tools faces challenges in maintaining consistent temperature conditions during the deposition of coating films, leading to variations in film quality and cutting performance, with issues such as temperature fluctuations and uneven heating causing peeling-off of the coating film.
Innovation Solution
The apparatus includes a deposition chamber with a pre-treatment chamber and post-treatment chamber connected through vacuum valves, featuring a conveying line with a heating region adjacent to the deposition region, where cutting tools are heated before entering the deposition area, and a carrier-waiting region to maintain consistent temperature, ensuring uniform coating film deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cutting tool is conveyed from pre-treatment chamber to deposition chamber, then the deposition process is completed, but the cutting tool temperature reduces during conveying and waiting periods
Solution Approach 1:
The cutting tool is pre-heated to the appropriate temperature in the pre-treatment chamber before entering the deposition chamber. This preliminary heating ensures that even during the conveying and waiting periods, the tool maintains sufficient temperature for quality deposition.
Solution Approach 2:
The heating action continues through the deposition chamber with heating means positioned to maintain temperature during the deposition process. This continuous heating ensures that the cutting tool temperature does not drop during conveying and waiting periods, maintaining deposition quality throughout the process.
2Productivity
If the pallet is conveyed during deposition, then the deposition process is efficient, but temperature difference between front and rear sides of pallet is formed causing film quality dispersion
Solution Approach 1:
Heating means are positioned at multiple locations within the deposition chamber, including front and rear sides of the pallet, to provide localized heating. This ensures that temperature differences between front and rear sides of the pallet are minimized, maintaining uniform film quality across all cutting tools even during conveyed deposition.
