Ultrasonic Weld Head with Guide Surface for Material Edge Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices fail to maintain proper orientation of cover material with respect to underlying structures, resulting in poor finishes and high scrap rates due to inefficient bonding processes with longer cycle times.
Innovation Solution
An apparatus with a weld head and guide surface system secures the edge of the material by advancing along a guide chain, using a rotatable weld head with projections to transfer energy and bond the cover material to the underlying structure, ensuring accurate positioning and bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current bonding devices are used to secure cover material, then the bonding process can be completed, but the cover material orientation becomes improper resulting in poor finish quality
Solution Approach 1:
The guide surface is positioned adjacent to the edge before bonding occurs, pre-establishing the correct orientation and position of the cover material. This preliminary positioning action ensures that when bonding takes place, the material is already in the desired orientation, preventing poor finish quality and eliminating the need for rework.
2Productivity
If current bonding devices are used, then bonding can be performed, but the cycle time becomes longer than desired
Solution Approach 1:
The guide surface maintains continuous contact with the cover material edge throughout the bonding process, ensuring uninterrupted positioning. This continuous guidance action allows the bonding head to move along the material without stopping to reposition it, maintaining bonding effectiveness while significantly reducing cycle time.
3Productivity
If the cover material is not properly positioned during bonding, then the process can continue, but sagging and wrinkles occur resulting in high scrap rates
Solution Approach 1:
The guide surface acts as an intermediary between the bonding head and the cover material edge. It provides a stable reference surface that maintains proper material positioning throughout the bonding process, preventing sagging and wrinkles. This intermediary guidance ensures high manufacturing precision while enabling continuous production with minimal scrap.
