Coating Needle Apparatus Dynamic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of electronics requires precise control of the coating amount applied by a coating needle, which varies due to differences in container manufacturing, leading to inconsistencies even when using the same coating conditions.
Innovation Solution
A coating apparatus with a controller that adjusts operation parameters such as standby time, contact time, and push amount based on the specific container used to maintain consistent coating amounts, using a coating unit with a replaceable container and driving devices to move the needle and unit relative to the target object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If containers are replaced to supply liquid material, then productivity is improved, but manufacturing precision deteriorates due to individual differences in container diameters
Solution Approach 1:
The system changes operational parameters (coating speed, standby time, contact time, push amount) based on the specific container being used. By adjusting these parameters dynamically, the system compensates for individual differences in container diameters and maintains consistent coating amounts across different containers, thereby resolving the contradiction between productivity improvement through container replacement and manufacturing precision maintenance.
2Ease of operation
If coating operation is performed under the same conditions, then ease of operation is improved, but manufacturing precision deteriorates due to container variations
Solution Approach 1:
The system automatically detects the container being used and self-adjusts the operational parameters without requiring manual intervention. The controller automatically sets appropriate coating speeds, standby times, contact times, and push amounts based on container characteristics, allowing the system to maintain both ease of operation and manufacturing precision simultaneously.
3Productivity
If miniaturization is pursued, then productivity is improved, but manufacturing precision deteriorates due to smaller coating amounts requiring tighter control
Solution Approach 1:
The system dynamically adjusts multiple operational parameters (coating speed, standby time, contact time, push amount) based on real-time container identification and characteristics. This dynamic adaptation allows the system to maintain precise control over coating amounts even as miniaturization demands smaller, more critical coating quantities, thereby supporting both productivity improvement through miniaturization and manufacturing precision maintenance.

AI summary
A coating apparatus applies a liquid material to a surface of a target object using a coating needle. The coating apparatus includes a coating unit having a coating needle and a container to hold a liquid material, a driving device configured to move the coating needle up and down, a Z-axis table configured to move the coating unit up and down, and a controller configured to drive the driving device and the Z-axis table to perform a coating operation. The controller adjusts the coating amount of the liquid material by controlling the driving device and the Z-axis table in accordance with an operation parameter set corresponding to the coating unit attached.
