Laser Cutting Alignment for Variable-Size Display Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for laser-cutting display materials are inefficient due to the need for precise alignment of display materials and cutting devices, which is time-consuming and complex, especially when dealing with materials of varying sizes.
Innovation Solution
A method and device that utilize a loader robot with pickup pads and a pre-alignment system, where the laser pointer aligns with teaching points to standardize pickup positions, allowing for consistent alignment and processing of display materials regardless of size, and a pre-alignment table with vacuum holes to facilitate accurate placement and cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If precise alignment of display materials and cutting devices is performed for reliable laser cutting, then cutting accuracy is improved, but processing time increases and efficiency decreases
Solution Approach 1:
The system performs preliminary alignment by projecting a laser pointer to identify teaching points on display materials before the actual cutting process. This pre-alignment step establishes reference positions that guide the cutting head, eliminating the need for time-consuming real-time alignment adjustments during cutting operations.
Solution Approach 2:
The patent replaces complex mechanical alignment mechanisms with an optical system using laser pointers and vision recognition. The laser pointer projects reference marks that are detected by vision sensors, automatically determining material positions and orientations without requiring manual mechanical adjustment of the cutting device.
2Manufacturing precision
If traditional alignment methods are used for display materials of varying sizes, then alignment accuracy can be maintained, but the complexity of the alignment process increases
Solution Approach 1:
The laser pointer system serves multiple functions: it projects alignment reference marks, defines teaching points for vision recognition, and establishes coordinate systems for materials of any size. This universal approach works for all display material dimensions without requiring different alignment procedures or additional equipment.
Solution Approach 2:
The system automatically identifies teaching points on display materials through vision recognition of the laser pointer marks, and autonomously calculates alignment parameters. The process requires no manual intervention for alignment adjustments, as the system self-calibrates by detecting the projected references and automatically adapting to each material's specific dimensions and position.

AI summary
A method for laser cutting display materials includes loading respective display materials from a tray, and a cutting dummy portions of the loaded display materials. The loading operation includes arranging a loader robot in the vicinity of the tray, aligning, at a first teaching point of the display materials, a laser pointer emitted from the loader robot, and picking up the display materials through at least one pickup pad of the loader robot.
