Parallel-Axis Press-Bonding Roller for Curved Adhesive Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive delivery devices struggle to smoothly deliver adhesive bodies along narrow and sharply curved lines, particularly with yarn-like adhesives that are difficult to follow complex shapes due to their flexibility and ease of bending.
Innovation Solution
An adhesive body delivery device featuring a main body with a turning portion and a press-bonding roller, where the turning portion is mounted to be relatively turnable around a first axis, and the press-bonding roller is turnable around a second axis parallel to the first, ensuring a predetermined distance between the axes to facilitate smooth delivery and sticking of the adhesive body along curved paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional sticking jig or transfer tool is used, then the adhesive body can be delivered along gently curved lines, but the adhesive body cannot follow movements along narrow and sharp curved lines
Solution Approach 1:
The pressing portion is made independently movable relative to the main body through a turning mechanism. The pressing portion can rotate around a second turning axis that is parallel to and separated from the first turning axis of the main body, allowing dynamic adjustment of the pressing position and angle to adapt to sharp curved paths
Solution Approach 2:
The invention introduces a second turning axis parallel to the first turning axis, creating a two-axis rotational system. This dimensional addition allows the pressing portion to move not only with the main body's turning but also independently adjust its orientation, enabling navigation through narrow and sharp curves that a single-axis system cannot handle
2Device complexity
If the press-bonding portion is mounted close to the turning axis, then the device structure is compact, but the adhesive body delivery stability deteriorates
Solution Approach 1:
The invention optimizes the distance parameter between the first and second turning axes. By setting this distance to a predetermined value, the design achieves a balance between structural compactness and delivery stability, allowing the pressing portion to maintain stable adhesive body control while keeping the overall device structure relatively compact
3Stability of the object's composition
If a rigid transfer tool is used, then the tool structure is stable, but the tool cannot easily follow complex curved shapes
Solution Approach 1:
The invention introduces dynamic movement capability to the pressing portion through the turning mechanism. While the main body maintains structural stability, the pressing portion can dynamically adjust its position and orientation by rotating around the second turning axis, enabling the system to follow complex curved shapes without sacrificing overall structural integrity
