Description

[0001] This invention relates to the field of cutting device technology, and in particular to a laser cutting device for artificial eyelashes and its manufacturing method. Background Technology

[0002] The main raw materials for making false eyelashes in existing technologies include synthetic fiber materials, glue, and eyeliner gel. Some specialized tools such as brushes, scissors, and molds are required. The fiber material is processed, typically by dividing it into bundles of different lengths to meet the needs of false eyelashes of varying lengths and densities.

The mold is then placed in a drying chamber or uses special heating equipment to accelerate the curing of the glue and ensure a strong bond between the fibers. Technical issues

[0051] This invention provides a laser cutting device for artificial eyelashes. This device can process a single piece or sheet of material, creating various patterns using laser technology, and then shaping it into eyelashes that consumers can apply to their skin or eyelashes. This technology enables laser cutting of various shapes from a single piece or sheet of material, including but not limited to eyelash shapes. The substrate includes, but is not limited to, PC and PET materials. It solves the pain point of quickly creating various shapes from a single piece or sheet of material, offering easy forming, high speed, and ultra-thinness, achieving thicknesses of 0.125, 0.3, 0.7, and 0.5 mm, and various colors such as black and gold. PET needs to be printed black beforehand; other materials do not require pretreatment before laser cutting. The laser cutting device for artificial eyelashes of this invention has the advantages of simplicity, lightness, and high speed.

[0052] Referring to Figures 1-3, this embodiment of the invention provides a laser cutting device for artificial eyelashes, including: a frame 1 and a vacuum working plate 14, a laser component, an X-axis linear motion mechanism, and a Y-axis linear motion mechanism disposed on the frame 1; wherein, the vacuum working plate 14 is fixedly disposed on the top of the frame 1 for fixing the substrate; the Y-axis linear motion mechanism is fixedly disposed on the frame 1, and the X-axis linear motion mechanism is disposed on the Y-axis linear motion mechanism and connected to the laser component; the Y-axis linear motion mechanism and the X-axis linear motion mechanism are used to drive the laser component to move above the vacuum working plate 14; the laser component is used to emit laser light to cut the substrate into an eyelash shape. Embodiments of the present invention

[0053] In some embodiments, the laser assembly includes a laser 5, an optical path control assembly, and a galvanometer 10. The laser 5 is fixedly mounted at the rear of the frame 1 and is used to generate laser light. The optical path control assembly guides the laser light to the galvanometer 10, which directs the laser beam towards the vacuum working plate 14. The galvanometer 10, as a key component for laser direction control, can quickly and accurately adjust the direction of the laser beam. This allows the laser beam to move flexibly above the vacuum working plate 14 along a preset trajectory, achieving precise cutting of complex eyelash shapes. The integrated design of key components such as the laser 5, optical path control assembly, and galvanometer 10 makes the entire laser assembly compact, easy to install and maintain. This highly integrated system also improves the reliability and durability of the device and reduces the failure rate.

[0054] In some embodiments, the optical path control assembly includes a first reflector 7, a second reflector 8, and a third reflector 9; wherein, the first reflector 7 is fixedly disposed at the fixed end of the X-axis linear movement mechanism, and is used to deflect the laser generated by the laser 5 by 90 degrees in the horizontal plane; the second reflector 8 is fixedly disposed at the top of the support bracket 11, the support bracket 11 is fixedly connected to the movable end of the X-axis linear movement mechanism, and the second reflector 8 is used to deflect the laser reflected by the first reflector 7 by 90 degrees in the vertical plane; the third reflector 9 is fixedly disposed at the bottom of the support bracket 11, and is used to deflect the laser reflected by the second reflector 8 by 90 degrees in the vertical plane and guide it into the galvanometer 10.

[0055] In some embodiments, a CCD module 12 is fixedly mounted on the support bracket 11. The CCD module 12 is used to acquire processing images. As a high-precision image acquisition device, the CCD module 12 can capture processing images during the laser cutting process in real time. This allows operators to intuitively monitor the cutting progress, cutting quality, and substrate condition, thereby promptly identifying and correcting potential problems. By analyzing the processing images acquired by the CCD module 12, the system can accurately calculate the actual position of the laser beam and the deviation of the cutting path. This real-time feedback mechanism helps adjust the movement trajectory of the laser components and laser parameters to ensure that the cutting accuracy meets the preset requirements.

[0056] In some embodiments, a displacement sensor 13 is fixedly mounted on the support bracket 11. The displacement sensor 13 can measure the displacement of the support bracket 11 (or associated components, such as the laser assembly, X-axis linear motion mechanism, Y-axis linear motion mechanism, etc.) in real time and accurately. By integrating the displacement sensor 13 with the control system, a closed-loop control system can be constructed. In this system, the displacement sensor provides real-time position data, and the control system adjusts the moving speed and direction of the laser assembly based on this data to ensure accurate tracking of the cutting path.

[0057] In some embodiments, the bottom of the laser 5 is fixedly connected to the frame 1 via a first bracket 4, and the laser 5 is covered by a laser cover 6. The laser cover 6 serves to protect the laser 5, and has heat dissipation holes for heat dissipation.

[0058] In some embodiments, the frame 1 is provided with an exhaust gas inlet 15 for absorbing exhaust gas generated during laser cutting of the substrate.

[0059] In some embodiments, referring to FIG4, both the X-axis linear movement mechanism and the Y-axis linear movement mechanism include a motor 16, a lead screw 17, a lead screw nut 18, a slider 19, and a housing 20. The motor 16 is located at one end of the housing 20; one end of the lead screw 17 is fixedly connected to the output shaft of the motor 16 and rotatably connected to the inner wall of the housing 20; the lead screw nut 18 is threadedly connected to the lead screw 17; the bottom of the slider 19 is fixedly connected to the lead screw nut 18; and the slider 19 is slidably connected to the edge of the housing 20. By driving the lead screw 17 to rotate via the motor 16, the lead screw nut 18 moves linearly along the lead screw 17, thereby achieving high-precision positioning. This transmission method features high transmission accuracy and precise positioning, meeting the high-precision requirements of the laser eyelash cutting device for the cutting position.

[0060] The top of the frame 1 is equipped with a cover 2, and a flip-top door 3 is provided on one side of the cover 2. The cover 2 serves to protect its internal parts, and the flip-top door 3 facilitates loading and unloading.

[0061] Referring to Figure 5, this embodiment of the invention also provides a method for manufacturing artificial eyelashes, based on an artificial eyelash laser cutting device, the method comprising the following steps:

[0062] S1. Fix the substrate onto the vacuum working plate 14;

[0063] S2. Set the laser power, wavelength, and pulse width; set the cutting power and speed. By adjusting parameters such as laser power, wavelength, pulse width, and cutting speed and power, it is possible to flexibly adapt to substrates of different materials, thicknesses, and shapes, thereby creating a variety of artificial eyelashes. This customizability makes it possible to meet the needs of different customers.

[0064] S3. The laser assembly is moved above the vacuum working plate 14 by the Y-axis and X-axis linear movement mechanisms to cut the substrate into an eyelash shape to form artificial eyelashes. This manufacturing method automates the entire process from substrate fixing to cutting and shaping using a laser cutting device. This not only significantly improves production efficiency but also reduces the complexity and cost of manual operation.

[0065] S4. Softening and Shaping Artificial Eyelashes. Softening and shaping artificial eyelashes further enhances their shape stability and durability. This step helps ensure the final product maintains its shape and comfort during wear and use.

[0066] In some embodiments, the substrate includes synthetic fibers, natural fibers, or combinations thereof; by using synthetic fibers, natural fibers, or combinations thereof as the substrate, the needs of different users for artificial eyelash materials can be met, taking advantage of the durability and consistency of synthetic fibers as well as the comfort and environmental friendliness of natural fibers, thereby improving the market adaptability and user satisfaction of the product.

[0067] The substrate is printed in black before cutting, which ensures the uniformity and consistency of the artificial eyelash color, avoids color difference problems that may be caused by subsequent dyeing, and simplifies the production process and improves production efficiency.

[0068] The thickness of the substrate ranges from 0.125mm to 0.7mm; the thickness of the artificial eyelashes can be adjusted according to different design requirements, so that they can maintain a light and natural appearance while having sufficient strength and durability.

[0069] The vacuum working plate 14 has a vacuum level of -0.08MPa to -0.1MPa; the laser power range is 10W to 100W, the wavelength is 10nm to 4nm, the pulse width is 10ns to 100ns, and the cutting speed is 10mm / s to 300mm / s; the movement accuracy of the Y-axis linear movement mechanism and the X-axis linear movement mechanism is 0.01mm; this ensures the stability of the substrate during the cutting process. Combined with the precise control of laser power, wavelength, pulse width, and cutting speed, as well as the high-precision movement (0.01mm) of the Y-axis and X-axis linear movement mechanisms, it can achieve high-precision cutting of complex eyelash shapes, ensuring product consistency and aesthetics.

[0070] The softening and setting temperature is 80℃ to 120℃, and the softening and setting time is 10s to 60s; softening is carried out by hot air, steam or softening agent; so that it forms a natural curved shape while maintaining the elasticity and flexibility of the fiber.

[0071] Applying waterproofing, oil-repellent, or antibacterial agents to softened and styled artificial eyelashes significantly improves their usability and hygiene. Waterproofing and oil-repellent treatments prevent artificial eyelashes from being affected by sweat, oil, or cosmetics during daily use, extending their lifespan; antibacterial treatments reduce the risk of bacterial growth, making them suitable for users with sensitive skin.

[0072] In some embodiments, after the artificial eyelashes are softened and shaped, length, curvature, and color are measured; this ensures that the size, shape, and color of each batch of artificial eyelashes meet the design requirements, reduces the defect rate, and improves the consistency and reliability of product quality.

[0073] In one specific embodiment, the method for detecting the curvature of artificial eyelashes includes:

[0074] Image acquisition steps: Use a high-resolution camera to capture images of the artificial eyelashes from the side.

[0075] Image preprocessing steps: Convert the image to grayscale, remove noise using Gaussian filtering, and separate the eyelashes from the background using binarization.

[0076] Contour extraction steps: Use an edge detection algorithm (such as Canny) to extract the contour of the eyelashes and extract the main contour line of the eyelashes.

[0077] Curvature calculation steps: Fit the eyelash contour into a curve (such as polynomial fitting or spline curve), calculate the curvature or arc value of the curve, output the curvature detection result, and compare it with the preset standard range.

[0078] Furthermore, a high-resolution camera is used to capture images of the artificial eyelashes not only from the side but also from frontal and oblique angles to obtain more comprehensive information about the eyelash morphology. Multi-angle image fusion technology is then used to generate three-dimensional eyelash images, providing a richer data foundation for subsequent processing and improving data processing accuracy.

[0079] After converting the image to grayscale, the noise is further processed. The processing methods include: extracting features from the input image, including the image's grayscale value, gradient, and texture.

[0080] Based on the extracted features, a deep learning model (such as a convolutional neural network CNN) is used to detect noise in the image and generate a noise mask.

[0081] The noise in the image is removed by using a mask, such as smoothing the noisy area or interpolating using neighboring pixels, in order to recover a more realistic image content.

[0082] The noise-removed image is reconstructed to ensure image continuity and consistency.

[0083] In some embodiments, after softening and shaping, artificial eyelashes are vacuum-packed, aseptically packaged, or moisture-proof packaged. This effectively protects the artificial eyelashes from contamination or damage during transportation and storage, extends the product's shelf life, and provides users with a more hygienic and safer experience. Industrial applicability

[0084] In the above embodiments, by combining the X-axis linear movement mechanism and the Y-axis linear movement mechanism, the laser assembly can perform precise two-dimensional movement above the vacuum working plate. This high-precision movement control ensures that the laser can accurately cut the substrate according to the preset eyelash shape, thereby achieving a high-precision cutting effect. This device achieves rapid and continuous cutting of the substrate by automatically controlling the movement of the laser assembly and the laser emission. Compared to traditional manual or mechanical cutting methods, this automated production method greatly improves production efficiency and product quality consistency. The vacuum working plate is fixedly mounted on the top of the frame to hold the substrate. Vacuum adsorption effectively prevents the substrate from moving or deforming during cutting, thus ensuring the stability and accuracy of the cutting. This helps to obtain eyelash-shaped cut parts with neat edges and precise shapes. The design of this device allows for cutting different types of substrates; only parameters such as laser power, movement speed, and cutting path need to be adjusted. This flexibility makes the device suitable for cutting substrates of different materials, thicknesses, and shapes.
