Vibrating Touch Plate Separation for Laser-Cut Metal Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In laser cutting processes, the narrow cut width and heat-induced distortion can cause products to overlap with skeletons, leading to interference issues during separation, which existing shock separation techniques are ineffective in addressing.
Innovation Solution
A product taking-out apparatus equipped with a suction part, a touch plate that vibrates when in contact with the product, and a controller to manage the lifting and vibration of the product to separate it from the skeleton effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If laser cutting process is used to cut product from workpiece, then cutting precision is improved, but product may overlap with skeleton vertically causing separation difficulty
Solution Approach 1:
The patent applies vibration to the touch plate to generate vibrational force that separates the product from the skeleton when they overlap vertically. The vibrator drives the touch plate to vibrate, and this vibration transmits to the product-skeleton interface to break the interference and enable successful separation.
Solution Approach 2:
The touch plate serves as an intermediary element between the suction part and the product. It transmits both suction force and vibrational force to the product, facilitating separation from the skeleton. The touch plate mediates the interaction between the lifting mechanism and the workpiece components.
2Ease of operation
If shock separation technique is applied to separate product from skeleton, then friction-based combined state is resolved, but vertical overlapping of product and skeleton cannot be resolved
Solution Approach 1:
The patent replaces the shock separation technique with continuous vibration applied through the touch plate. This vibration is specifically effective for vertical overlapping cases where shock separation fails, as it continuously acts on the product-skeleton interface to prevent or resolve interference during the lifting process.
Solution Approach 2:
The system transitions from a static shock application to a dynamic continuous vibration process. The vibrator operates continuously during the lifting phase, adapting to the real-time interaction between product and skeleton, making the separation process more versatile for different interference scenarios.
3Manufacturing precision
If narrow cut width is used in laser cutting, then manufacturing precision is improved, but product may get under skeleton causing interference
Solution Approach 1:
The vibration applied through the touch plate counteracts the harmful effect of the product getting under the skeleton. By vibrating the touch plate during lifting, the system prevents the product from adhering to or interfering with the skeleton, resolving the problem caused by narrow cut widths.
Solution Approach 2:
The vibration is applied in advance during the lifting process to prevent the interference problem from occurring. By continuously vibrating the touch plate as the product is lifted, the system proactively prevents the product from getting under the skeleton, rather than correcting the problem after it occurs.
