10. A method for applying the eyelash shaping system based on laser cutting film according to claim 9, characterized in that: The following steps are involved: S1. Design Input and Modeling: Receive user-inputted design parameters for eyelash shape, size, and density, import graphic files, and convert them into 3D digital models. Use built-in graphic processing algorithms and a hierarchical design rule library to verify and correct the model, generate an initial design plan, and predict production process difficulties through design-process linkage analysis. S2. Process parameter optimization: Based on the initial design plan and combined with the laser cutting process knowledge base, a reinforcement learning algorithm is used to optimize the parameters of laser power, cutting speed, pulse frequency, and spot diameter. The environmental perception module collects temperature, humidity, and material property data in real time to dynamically adjust the strategy. The optimized parameters are then evaluated for robustness to ensure anti-interference capabilities. S3. Cutting Path Planning: Based on the 3D digital model and optimized process parameters, an improved simulated annealing algorithm is used to generate the cutting path. The design structure complexity and process implementation difficulty are incorporated into the objective function. Multiple schemes are compared, forming a scheme library for easy access. The path is adjusted in real time in conjunction with the production control module. S4. Production process control: Convert cutting paths and process parameters into control instructions, communicate with laser cutting equipment, receive real-time feedback from equipment operation and adjust instructions, and simultaneously perform production scheduling management to ensure smooth execution of the cutting process; S5. Online quality monitoring: Use image recognition technology to detect the quality indicators of eyelash size accuracy, shape integrity, and edge smoothness after cutting in real time. If any abnormality is found, it will be fed back to the production control module in time, and the detection data will be stored for subsequent analysis.
