Solution Overview
Problem
Existing three-dimensional screen printing systems face issues with excessive heating of workpiece carriers during the drying process, which can affect the quality and accuracy of screen printing workpieces, particularly after multiple passes through a drying device.
Innovation Solution
A device and method that incorporates a drying device capable of simultaneously drying screen printing workpieces and cooling workpiece carriers, preventing excessive heating by maintaining the carrier at a low temperature, thus improving process reliability and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workpiece carriers are passed through a drying device multiple times to dry layered screen-printed workpieces, then the drying effectiveness is improved, but the workpiece carrier temperature increases excessively compromising print layer quality
Solution Approach 1:
The drying device is divided into two independent functional zones: a drying section with heating elements for drying the screen-printed workpiece, and a cooling section with cooling elements for cooling the workpiece carrier. This segmentation allows simultaneous drying and cooling operations without thermal interference, resolving the contradiction between drying effectiveness and carrier temperature control
Solution Approach 2:
Different thermal treatments are applied to different parts of the system: the workpiece receives heating in the drying section while the workpiece carrier receives cooling in the cooling section. This local differentiation of thermal conditions allows the workpiece to be dried effectively while the carrier remains at acceptable temperature levels
2Productivity
If continuous drying operations are performed on screen-printed workpieces, then productivity is improved, but workpiece carrier heating accumulates negatively impacting production accuracy
Solution Approach 1:
The workpiece carrier undergoes continuous cooling during its passage through the cooling section, ensuring that thermal accumulation is prevented even during continuous production operations. This continuous cooling action maintains manufacturing precision while allowing uninterrupted drying cycles
Solution Approach 2:
The drying device merges two previously separate operations (drying and cooling) into a single integrated device where both functions occur simultaneously in different sections. This combination allows continuous operation without the need to separate drying and cooling steps, maintaining both productivity and precision
