Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing devices for cutting and milling panels are inefficient in terms of economic costs, space requirements, automation complexity, and machining accuracy, particularly for producing high-quality workpieces with minimal post-processing effort, especially when dealing with large-format panels.
Innovation Solution
A processing device equipped with a fixing element that securely holds the workpiece during cutting, allowing for precise control and eliminating irregularities at the cutting edge, combined with a movable processing unit and integrated transport system for efficient waste management and flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If panel saws are used for cutting large-format panels, then cutting capability is achieved, but investment costs and space requirements increase significantly
Solution Approach 1:
The processing device segments the panel processing function into a compact unit that can be integrated into existing CNC routing systems, rather than requiring a separate large-format panel saw. This allows cutting capability to be achieved within the same machine footprint as routing operations.
Solution Approach 2:
The device combines multiple functions (routing, cutting, and now panel division) into a single CNC machine platform, eliminating the need for separate dedicated panel saw equipment and reducing overall space requirements while maintaining cutting capability.
2Ease of manufacture
If two consecutive sawing steps are used in one machine, then panel division is achieved, but device complexity and investment costs increase
Solution Approach 1:
The invention merges the panel division cutting function with the existing CNC routing system into a single integrated device. The same spindle and motion control system perform both routing and panel division operations, eliminating the need for separate sawing steps or duplicate equipment.
3Ease of manufacture
If panel saws are used for cutting, then cutting function is achieved, but machining accuracy deteriorates compared to CNC routers
Solution Approach 1:
The invention transfers the high-precision motion control and positioning systems from CNC routing technology to panel division operations. By using the same CNC controller, spindle, and motion guidance mechanisms, the device achieves routing-level angular accuracy (within 0.05mm) for cutting operations.
4Manufacturing precision
If fixing elements are added to hold workpiece during cutting, then cutting edge quality improves, but device complexity increases
Solution Approach 1:
The workpiece is secured to the table surface through self-adhesive properties or vacuum suction, eliminating the need for complex mechanical clamping devices. The table surface itself provides the fixing function, keeping the device simple while ensuring workpiece stability during cutting for high-quality edges.
5Reliability
If vacuum table is used for clamping raw panel, then workpiece securing is achieved, but energy consumption and operational complexity increase
Solution Approach 1:
The invention uses disposable adhesive tapes or temporary adhesive surfaces applied directly to the workpiece or table, replacing energy-intensive vacuum systems. These low-cost adhesive elements provide sufficient securing during the cutting operation without requiring continuous energy input.
