Foil Transfer Apparatus Movable Detection Jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foil transfer apparatuses face limitations in flexibility due to interference between the detection jig and the transfer tool, restricting the placement of transfer objects and requiring adjustments in object position or transfer data.
Innovation Solution
A foil transfer apparatus with a detachable detection jig that can be positioned anywhere on the support base, allowing for flexible placement of transfer objects by overlapping with the transfer region, and a controller that determines the presence of the pressing body using detectors and a reference length, enabling precise detection and adaptation to different object shapes and foil image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detection jig is fixed at a predetermined position to detect the pressing body, then the detection function is ensured, but the flexibility in placement of transfer objects is reduced due to interference between the detection jig and transfer tool
Solution Approach 1:
The detection jig is made movable along the transfer region instead of being fixed at a predetermined position. This allows the detection jig to dynamically adjust its position to avoid interfering with the transfer tool while maintaining its detection function, thereby resolving the contradiction between reliable detection and placement flexibility.
Solution Approach 2:
The detection function is separated from the transfer tool by using an independent, movable detection jig. This segmentation allows the detection jig to operate independently at different positions, enabling both reliable detection and flexible transfer object placement without mutual interference.
2Measurement precision
If the detection jig overlaps with the transfer region to enable detection, then detection accuracy is improved, but interference with the transfer tool occurs, requiring changes in object position or transfer data
Solution Approach 1:
The detection jig can move to different positions within the transfer region, allowing it to maintain detection accuracy by overlapping with the transfer region when needed, while avoiding interference with the transfer tool by repositioning when the transfer tool is present, eliminating the need to change object position or transfer data.
3Reliability
If the detection jig is fixed to ensure stable detection, then detection reliability is maintained, but the ability to adapt to different transfer object shapes and foil image data is reduced
Solution Approach 1:
The movable detection jig can be repositioned according to different transfer object shapes and foil image data requirements, providing adaptability while maintaining detection reliability through consistent detection functionality at various positions within the transfer region.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances flexibility in placing transfer objects by allowing the detection jig to be positioned according to the object's shape or foil image data, preventing interference and ensuring accurate detection of the pressing body's presence, thereby improving the transfer process.
Implementation Method 1
a first detector to detect a first height position of the transfer tool in the top-bottom direction when the transfer tool is lowered and partially brought into contact with the detection jig
Implementation Method 2
a second detector to detect a second position of the transfer tool in the top-bottom direction when the transfer tool is lowered and partially brought into contact with the detection jig at a second position at which the pressing body does not overlap with the detection jig in plan view and at least a portion of the case body overlaps with the detection jig in plan view
Implementation Method 3
a determiner to determine whether the pressing body is present or not based on the reference length, the first height position, and the second height position
Implementation Method 4
the thermal transfer foil is heated by applying light with the thermal transfer foil being pressed from above with a transfer tool including a light source for applying light
Implementation Method 5
the adhesive layer in a pressed portion of the thermal transfer foil is melted and attached to the surface of the transfer object
Implementation Method 6
and then is cured by heat dissipation
