Description

Technical Field

[0001] This utility model relates to the field of laser embroidery technology, and more specifically, to a multi-channel embroidery cutting device. Background Technology

[0002] Laser embroidery machines are advanced equipment that combines laser technology with traditional embroidery techniques. They use a high-precision laser head to replace or assist traditional embroidery needles, enabling automated embroidery of complex patterns. A focused laser beam is used to ablate or change the color of the fabric surface to form intricate patterns. No physical contact is required, avoiding the problems of broken or replaced threads in traditional embroidery.

[0003] Furthermore, by adjusting the laser power and speed, the ablation depth of the material can be controlled to achieve relief effects or gradient colors.

[0004] Traditional laser embroidery machines typically only support one production line, limiting the number of embroidered items that can be produced. Attempts have been made to shorten the production cycle by controlling the time it takes for the laser beam to ablate the fabric, but the uneven fabric thickness makes it difficult to standardize the degree of ablation.

[0019] A multi-channel embroidery cutting device, see Figure 1 , Figure 2 as well as Figure 3 The housing 1 serves as the main supporting structure of the entire device. It is made of aluminum alloy and anodized to improve corrosion resistance and heat dissipation. The interior of housing 1 is precision-machined to form a smooth inner wall, reducing scattering and energy loss during laser transmission. A V-shaped clearance groove 10 is provided on one side of housing 1, with an opening angle of 60° and a depth of 10mm. A reinforcing rib is provided at the bottom of the clearance groove 10. The reinforcing rib has a rectangular cross-section, a width of 5mm, and a height of 8mm, and is fixed to the interior of housing 1 by welding. The design of the reinforcing rib enhances the overall rigidity of housing 1 and reduces deformation caused by external impacts or vibrations.

[0020] The main channel 2 is arranged along the axial direction of the housing 1 and is connected to the radio frequency laser 12. A beam splitter 5 is fixedly installed at the end of the main channel 2. The beam splitter 5 is fixed to the end of the main channel 2 by a threaded connection and is inclined at a 45° angle to the axis of the main channel 2. The surface of the beam splitter 5 is coated with a multilayer dielectric film, each layer of which is one-quarter the thickness of the laser wavelength and is composed of alternately deposited high-refractive-index and low-refractive-index materials. The installation position of the beam splitter 5 is precisely adjusted by a fine-tuning mechanism, which includes an adjusting screw and a locking nut. The adjusting screw is fixed inside the housing 1 by a threaded connection. Rotating the adjusting screw can change the angle of the beam splitter 5, and the locking nut is used to fix the adjusted angle position. The beam splitter 5 evenly distributes the laser in the main channel 2 into multiple sub-channels, dividing the main laser into two sub-lasers. The first sub-laser is emitted along the direction of the first sub-channel, and the second sub-laser is emitted along the direction of the second sub-channel. Finally, through the guiding mechanism, the two sub-lasers are emitted in a straight horizontal direction along the first and second sub-channels respectively. The guiding mechanism guides the laser to be emitted in a straight horizontal direction, so as to act on two different fabric embroidery production lines respectively, ensuring that the energy distribution of each channel is consistent.

[0021] The first sub-channel 3 and the second sub-channel 4 are respectively connected to the main channel 2, wherein the length of the first sub-channel 3 is 300mm and the length of the second sub-channel 4 is 200mm. The first sub-channel 3 is arranged in a Z-shape, and a guiding mechanism is arranged inside it along the direction away from the second sub-channel 4. The guiding mechanism includes at least two first reflectors 6 arranged in sequence. The first reflectors 6 are fixed inside the housing 1 by bolts and are inclined at a 45° angle to the horizontal plane. The surface of the first reflector 6 is coated with a high-reflectivity metal film with a reflectivity of not less than 99.5%.

[0022] The first sub-channel 3 is equipped with a first aperture stop 8 at its end. The size of the laser beam is controlled by an adjustment knob, with an adjustment range of 1mm to 5mm and an adjustment accuracy of 0.1mm. The adjustment knob of the first aperture stop 8 is provided with anti-slip texture, with a depth of 0.5mm and a spacing of 1mm, to facilitate the operator to quickly and accurately adjust the opening size.

[0023] The second sub-channel 4 is arranged along its axial direction and contains the aforementioned guiding mechanism. The guiding mechanism includes a second reflector 7, which is bolted to the inside of the housing 1 and inclined at a 45° angle to the horizontal plane. The surface of the second reflector 7 is also coated with a high-reflectivity metal film, with a reflectivity of not less than 99.5%. A cooling module is also provided on its back, which is attached to the second reflector 7 via thermally conductive silicone grease. A second aperture stop 9 is provided at the end of the second sub-channel 4. The size of the laser beam is controlled by an adjustment knob, with the adjustment range and precision being the same as the first aperture stop 8. Laser focusing lenses 11 are provided at the exit ends of both the first sub-channel 3 and the second sub-channel 4. The laser focusing lenses 11 are fixed to the channel exit by retaining rings, with a focal length of 50mm, which can further focus the output laser beam to improve ablation accuracy.

[0024] The exit ends of the first sub-channel 3 and the second sub-channel 4 are also equipped with protective covers. These covers, made of transparent quartz glass, are fixed to the outside of the housing 1 by clips and effectively prevent external dust and impurities from entering the channels without affecting the normal output of the laser. The opening and closing status of the protective covers is detected by a protective cover switch sensor, which is fixed to the outside of the housing 1 by bolts. If the sensor detects that the protective cover is not completely closed, it will send a signal to the control system to trigger an alarm mechanism.

[0025] Both the first sub-channel 3 and the second sub-channel 4 are equipped with laser detection sensors at their exit ends. These sensors are bolted to the outside of the housing 1 and are used to monitor the intensity and diameter of the laser beam in real time, ensuring that the output parameters meet preset requirements. If an abnormality is detected, the sensor sends a signal to the control system to trigger an alarm mechanism. The design differences between the first sub-channel 3 and the second sub-channel 4 optimize the laser transmission characteristics in different channels, thus adapting to the needs of various fabric materials and thicknesses. Adjusting the sub-channel length effectively compensates for energy loss in different channels, ensuring consistent laser intensity output from each channel.

[0026] In practical applications, the laser generated by the RF laser 12 enters through the main channel 2 and is split by the beam splitter 5 into the first sub-channel 3 and the second sub-channel 4. In the first sub-channel 3, the laser is reflected sequentially by two first reflectors 6 and finally exits horizontally after being adjusted by the first aperture stop 8. In the second sub-channel 4, the laser is reflected by the second reflector 7 and exits horizontally after being adjusted by the second aperture stop 9. The adjustment knobs of the first aperture stop 8 and the second aperture stop 9 are fixed to the ends of the sub-channels by threaded connections. Rotating the knobs changes the aperture opening size, thereby controlling the diameter and energy density of the laser beam. The laser focusing lens 11 further focuses the output laser beam, improving the ablation accuracy. The protective cover switch sensor detects the open and closed status of the protective cover. If the protective cover is not completely closed, the sensor sends a signal to the control system to trigger an alarm mechanism. The temperature sensor monitors the temperature change inside the housing 1 in real time. If the temperature exceeds a preset threshold, the sensor sends a signal to the control system to trigger the cooling module to start.

[0027] To enable those skilled in the art to fully understand and implement this invention, the following supplementary explanation of the operating principle and implementation steps of this invention is provided in conjunction with a specific application scenario.

[0028] In actual operation, the radio frequency laser 12 is first connected to the main channel 2, and the laser power, speed, and aperture sizes of aperture stops 8 and 9 are set via the control panel. The device is then started, and the laser beam generated by the radio frequency laser 12 enters from the main channel 2, and is uniformly split into the first sub-channel 3 and the second sub-channel 4 by the beam splitter 5. The multilayer dielectric film coated on the surface of the beam splitter 5 ensures the uniform distribution of laser energy, while its angle is precisely adjusted by a fine-tuning mechanism to avoid energy loss or beam deviation due to angular deviation.

[0029] After entering the first sub-channel 3, the laser beam is reflected sequentially by two first reflectors 6. The surface of each first reflector 6 is coated with a high-reflectivity metal film, with a reflectivity of no less than 99.5%, effectively reducing energy loss during laser transmission. Furthermore, a cooling module on the back of each first reflector 6 is attached to it via thermally conductive silicone grease, and coolant in internal micro-liquid cooling pipes continuously circulates, lowering the reflector temperature and extending its lifespan. After two reflections, the laser beam reaches the first aperture stop 8. The operator controls the diameter and energy density of the laser beam by rotating an adjustment knob to change the aperture opening size. The anti-slip textured design improves the feel during adjustment, facilitating quick and accurate adjustments.

[0030] Meanwhile, after entering the second sub-channel 4, the laser beam is reflected by the second reflector 7 and reaches the second aperture stop 9. The second reflector 7 also employs a high-reflectivity metal film design. The adjustment method for the second aperture stop 9 is the same as that for the first aperture stop 8, controlling the laser beam parameters through an adjustment knob. The length difference between the first sub-channel 3 and the second sub-channel 4 optimizes the laser transmission time in different channels, thereby compensating for energy loss and ensuring consistent laser intensity in both output paths.

[0031] After adjustment, the laser beam is further focused by the laser focusing lens 11 at the ends of the first sub-channel 3 and the second sub-channel 4. The focusing lens with a focal length of 50mm significantly improves the ablation accuracy. The focused laser beam is emitted horizontally for embroidery cutting on the fabric surface. The protective cover switch sensor detects the open and closed status of the protective cover in real time. If the protective cover is not fully closed, a signal is sent to the control system to trigger an alarm mechanism to ensure operational safety.

[0032] During device operation, a temperature sensor is used to monitor the temperature changes inside the housing 1 in real time. If the detected temperature exceeds a preset threshold, the sensor will send a signal to the control system.

[0033] Laser detection sensors are installed at the exit ends of the first sub-channel 3 and the second sub-channel 4 to monitor the intensity and diameter of the laser beam in real time. If an abnormality is detected, such as insufficient laser beam intensity or a diameter exceeding the preset range, the sensor will send a signal to the control system to trigger an alarm mechanism, reminding the operator to adjust parameters or check the equipment status in a timely manner.

[0034] Through the above steps, this device achieves multi-channel collaborative operation, significantly improving production efficiency. The beam splitter 5 evenly distributes a single laser beam to multiple sub-channels, enabling multiple laser heads to work simultaneously, meeting the demands of large-scale, high-efficiency production. Simultaneously, the precise adjustment functions of the first aperture stop 8 and the second aperture stop 9, combined with the focusing effect of the laser focusing lens 11, ensure the consistency of fabric ablation, solving the problem of inconsistent ablation levels caused by uneven fabric thickness in traditional equipment.

[0035] The housing has a V-shaped clearance groove 10 on one side, which provides clearance space for the first reflector 6 and the second reflector 7 on the first sub-channel 3 and the second sub-channel 4, respectively.

[0036] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
