Printer Mask Cleaning via Rotational Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers with fixed-direction cleaning sections struggle to effectively clean mask openings with complex patterns, as the cleaning mechanism moves in a constant direction parallel to the mask, failing to adequately clean all areas.
Innovation Solution
A printer with a cleaning section that moves relative to the mask in a predetermined direction parallel to its under surface, combined with a mask holding section capable of rotating about an axis perpendicular to the surface, allowing for adjustable inclination and reciprocation of the mask during cleaning, controlled by a sophisticated control system to optimize cleaning effectiveness.

Engineering Contradiction Analysis
1Ease of operation
If the cleaning device moves in a constantly fixed direction parallel with the mask, then the cleaning mechanism is simple, but some opening patterns of the mask cannot be effectively cleaned
Solution Approach 1:
The mask holding section is designed to dynamically change the mask's orientation during cleaning. The mask can be rotated about a vertical axis and tilted about a horizontal axis, transforming from a fixed static position to a dynamic adjustable position. This allows the cleaning section to effectively clean various opening patterns by adapting the mask's orientation during the cleaning process.
Solution Approach 2:
The mask holding section serves multiple functions: it holds the mask during cleaning, rotates the mask about a vertical axis to align different opening patterns with the cleaning direction, and tilts the mask about a horizontal axis to optimize the cleaning angle. This multi-functional design enables a single cleaning section to effectively clean various mask patterns without requiring multiple specialized cleaning mechanisms.
2Productivity
If the mask is fixed in position during cleaning, then the cleaning process is simple, but complex opening patterns cannot be adequately cleaned
Solution Approach 1:
The mask holding section enables dynamic repositioning of the mask during cleaning operations. By rotating the mask about a vertical axis and tilting it about a horizontal axis, the system adapts to different opening patterns and cleans more areas effectively, increasing overall cleaning coverage without requiring multiple cleaning sections.

AI summary
A printer includes: a mask; a cleaning section configured to perform cleaning of the mask by movement relative to the mask in a predetermined direction parallel with an under surface of the mask; a mask holding section capable of turning the mask about an axis perpendicular to the under surface of the mask while holding the mask; and a control section configured to perform a control such that the cleaning is performed on the mask placed in a predetermined position about the axis.
