Laminate Strip Cutting With Feedback Compensation for Component Shrinkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in accurately positioning electronic components within laminate strips during the cutting process, as the laminate material shrinks due to internal tension, leading to deviations from the desired position, which can result in components not being correctly positioned within the laminate components.
Innovation Solution
A method that utilizes a measuring device to detect deviations in the position of components relative to the conveying direction, allowing for real-time adjustment of the synchronous movement of the transport and gripper devices to ensure precise positioning of components during cutting, using distance values and offset calculations to correct for shrinkage and maintain accurate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the laminate strip is cut using a standard cutting device without position detection, then the cutting process is simple and fast, but the component position deviates from the target position due to material shrinkage
Solution Approach 1:
A measuring device detects the actual position of the component in the laminate component, and based on the detected deviation from the target position, the synchronous movement of the transport means and gripper device is controlled to compensate for the deviation. This feedback loop ensures that despite material shrinkage, the component is consistently positioned at the correct location in the cut laminate strip.
Solution Approach 2:
The patent replaces pure mechanical positioning with a combination of optical measurement and controlled synchronous movement. Instead of relying solely on mechanical precision, the system uses a measuring device to detect position and adjusts the transport and gripper movements accordingly, substituting mechanical rigidity with active compensation.
2Manufacturing precision
If the laminate material is handled without accounting for shrinkage, then the processing is straightforward, but the component ends up at an incorrect position after cutting
Solution Approach 1:
The measuring device continuously monitors the component position and provides feedback to the control system. Based on the detected deviation, the synchronous movement parameters are adjusted in real-time, ensuring that the component is always positioned correctly in the final cut product, compensating for material shrinkage effects.
Solution Approach 2:
The system performs preliminary measurement of the component position before cutting. Based on this preliminary detection, the synchronous movement is pre-adjusted to account for expected shrinkage, ensuring that when the cut is made, the component is already in the correct final position.
3Manufacturing precision
If synchronous movement control is implemented to compensate for shrinkage, then component positioning accuracy improves, but the system complexity increases
Solution Approach 1:
The control system receives position information from the measuring device and adjusts the synchronous movement of the transport means and gripper device accordingly. This feedback-based control ensures that the component is consistently positioned at the correct location in the laminate strip, compensating for material shrinkage during the lamination and cutting process.
Solution Approach 2:
The control system serves multiple functions: it coordinates the synchronous movement of the transport means and gripper device, processes measurement data from the measuring device, calculates the deviation from the target position, and adjusts the movement parameters to compensate for shrinkage. This multi-functionality reduces the need for separate dedicated systems.
