Automated Splice Device for Composite Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of pressure-bonding the rear end of one composite material sheet with the tip of another, known as splice work, is complex and inefficient in existing automated lamination devices.
Innovation Solution
A splice device with detection units, cutting parts, and a pressure-bonding mechanism controlled by a device that automatically cuts and bonds composite material sheets when residual amounts reach predetermined levels, ensuring accurate and efficient bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual splice work is performed to pressure-bond composite material sheets, then bonding can be achieved, but the process becomes complicated and inefficient
Solution Approach 1:
The system performs splice work automatically without manual intervention. The bonding mechanism self-activates when the composite material sheet runs out, detecting the condition and executing the pressure-bonding operation autonomously to join the next sheet, thereby eliminating manual splice operations and improving productivity
Solution Approach 2:
The manual mechanical splice operation is replaced with an automated bonding mechanism that uses pressure and heat (or ultrasonic vibration) to join composite material sheets. This substitution eliminates the need for manual cutting and bonding steps, simplifying the overall process while maintaining bonding functionality
2Productivity
If automated lamination is used, then productivity improves, but splice work remains manual and becomes a bottleneck
Solution Approach 1:
The bonding mechanism serves multiple functions: it bonds composite material sheets during normal lamination operations and automatically performs splice operations when sheets run out. This multi-functionality ensures that the same mechanism handles both routine bonding and emergency splice operations, achieving full automation without requiring separate manual intervention for splicing
3Loss of time
If manual splice work is performed, then flexibility is maintained, but time is lost due to manual intervention
Solution Approach 1:
The system prepares for splice operations in advance by continuously monitoring the composite material sheet supply. When the sheet runs out, the bonding mechanism is already positioned and ready to immediately perform the splice operation without requiring manual setup or intervention, thereby minimizing time loss and maintaining continuous production
