Vibration Welding Device Independent Position Adjusting Jigs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration welding devices face challenges in accurately adjusting the positions of the vibrating body and jig to accommodate manufacturing variations in resin materials, leading to reduced welding accuracy, especially with large-sized workpieces.
Innovation Solution
A vibration welding device equipped with a second jig that vibrates orthogonally to the stacking direction and a plurality of independently adjustable position adjusting jigs connected to it, allowing precise positioning of the second object to be welded relative to the vibrating body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a large-sized workpiece is welded by the vibration welding device, then the vibrating body and the jig become large in accordance with the workpiece, but the adjustment work for the positions of the vibrating body and the jig becomes very complicated and the welding time increases
Solution Approach 1:
The jig is divided into an upper jig and a base plate that can be independently adjusted. The upper jig holds the vibrating body and can be positioned separately from the base plate, allowing independent adjustment of each component to accommodate large workpiece dimensions without increasing overall adjustment complexity
Solution Approach 2:
The upper jig is made movable relative to the base plate through a raising and lowering drive unit, enabling dynamic adjustment of the vertical position. This dynamic capability allows the system to adapt to different workpiece sizes and positions without requiring complete reconfiguration of the entire welding device
2Manufacturing precision
If the upper jig and vibrating body are adjusted for lateral position, then the positional relationship in the width direction can be adjusted, but the positions cannot be adjusted for each portion of the material to be welded due to manufacturing variations
Solution Approach 1:
The positioning system is segmented into multiple independent adjustment mechanisms: lateral position adjustment for the upper jig, vertical position adjustment through the raising and lowering drive unit, and rotational angle adjustment. Each segment can be adjusted independently to compensate for manufacturing variations at different locations of the workpiece
Solution Approach 2:
Multiple positional parameters are made adjustable: lateral position (width direction), vertical position (height direction), and rotational angle. By changing these parameters independently, the system can adapt to manufacturing variations in different portions of the material to be welded, achieving high welding accuracy despite size and variation differences
