Description

Technical Field

[0001] This utility model relates to the field of template cutting technology, and more specifically, to a radio frequency laser for a template machine and the template machine thereof. Background Technology

[0002] Template sewing machines refer to fully automated template production that combines garment template CAD software, garment template sewing CAD software, and advanced CNC technology. This improves production efficiency and product quality, reduces the technical requirements for skilled workers, and replaces the original manually operated sewing machines with more automated, computer-controlled machines, reducing reliance on highly skilled personnel. This type of template sewing machine can only perform sewing operations and cannot perform cutting operations.

[0003] Traditional mechanical cutting methods, such as blade cutting, struggle to achieve high-precision cuts when cutting fabric due to the physical contact between the blade and the fabric, as well as errors in mechanical movement. Traditional cutting methods are relatively slow, and when cutting fabrics of different shapes and sizes, frequent blade changes or adjustments to the cutting equipment parameters are necessary. Furthermore, the blades wear out easily, requiring frequent replacements, resulting in low production efficiency and making it difficult to meet the demands of large-scale production.

[0004] However, the carbon dioxide laser tubes used for laser cutting today have problems such as large space occupation, need to be equipped with an additional water tank for cooling, long optical path and high energy loss, and short service life.

[0005] Therefore, how to solve the problems of existing cutting devices occupying a large space and having low cutting efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The core of this invention is to provide a radio frequency laser for a template machine that does not affect the footprint of the template machine 10. The laser output beam is precisely reflected, reducing energy loss due to long-distance transmission by only one reflection, thus increasing the energy density at the cutting point and improving cutting efficiency. Another core aspect of this invention is to provide a template machine that includes the aforementioned radio frequency laser, offering high cutting efficiency and ease of operation.

[0037] Please refer to Figure 1 and Figure 2 A radio frequency laser for a template machine includes a radio frequency laser body 1, a reflective structure 2, and a focusing structure 3.

[0038] Specifically, the radio frequency laser body 1 is located on one side of the template machine 10. It has a compact structure and does not occupy the production line space. The front end of the radio frequency laser body 1 is provided with a light outlet 11. The reflective structure 2 is located at the light outlet 11 so that the light beam emitted from the light outlet 11 enters the reflective structure 2 and undergoes one reflection. The laser beam emitted from the radio frequency laser body 1 enters the reflective structure 2 from the light outlet 11 and undergoes only one reflection in the reflective structure 2, so that the laser output beam is accurately reflected, reducing energy loss caused by long-distance transmission and concentrating the energy, thereby improving the cutting efficiency. The focusing structure 3 is located at the reflection outlet of the reflective structure 2 so that the light beam reflected by the reflective structure 2 is emitted from the cutting opening of the focusing structure 3. The light beam reflected by the reflective structure is focused by the focusing structure 3 and emitted, thereby realizing a high-efficiency cutting process.

[0039] The radio frequency laser body 1 is placed at the head position on one side of the template machine 10, which does not affect the footprint of the small template machine 10. This allows the small template machine 10 to be used in the hanging production line. The structure is reasonable and the laser output beam is accurately reflected, passing through only one reflection point, which reduces energy loss caused by long-distance transmission, enhances the energy density of the cutting point, reduces the number of times manual focusing and adjustment are required, and makes the cutting process smoother and faster.

[0040] The template machine using the above-mentioned method employs an RF laser for cutting fabric. RF lasers occupy little space, do not require water tank cooling, have a long service life, and offer precise energy, high processing efficiency, good stability, and easy operation, with relatively low technical requirements for operators.

[0041] In the above embodiment, the radio frequency laser body 1 is externally connected to a PWM dimming device for adjusting the power of the laser output.

[0042] It should be noted that the RF laser body 1 is externally connected to a PWM (Pulse Width Modulation) dimming device to control the laser output. By changing the duty cycle of the PWM signal, the average output power of the laser can be linearly controlled. The higher the duty cycle, the longer the laser's conduction time within one cycle, and the greater the output power; the lower the duty cycle, the lower the output power. The laser power can be precisely adjusted according to actual needs to achieve accurate energy control. The energy output of the RF laser is relatively stable and easy to adjust, enabling precise control of effective cutting of fabrics of different thicknesses and materials.

[0043] By combining the radio frequency laser body 1 with a PWM dimming device, the cutting energy output can be adjusted. This addresses the changes in energy demand caused by factors such as uneven fabric texture (e.g., variations in local thickness or fiber density) during the cutting process, thus improving cutting quality. For example, thinner fabrics like silk and chiffon require lower energy, while thicker fabrics like denim and wool require higher energy for effective cutting. Precise energy control effectively prevents problems such as excessive energy causing scorching or carbonization of the fabric edges, affecting its appearance and quality; or insufficient energy preventing complete fiber severing and incomplete cutting.

[0044] In the above case, the reflective structure 2 includes a sleeve 21 and a reflector 22 disposed inside the sleeve 21. One end of the sleeve 21 is connected to the light outlet 11, and the other end of the sleeve 21 is connected to the light-concentrating structure 3. The reflector 22 is disposed at the corner of the sleeve 21 so that the light beam entering the sleeve 21 is reflected by the reflector 22 and then enters the light-concentrating structure 3.

[0045] Understandably, the radio frequency laser beam is emitted from the output port 11, enters the sleeve 21 through the opening corresponding to the output port 11, and is emitted at the reflector 22 inside the sleeve 21. The reflected beam then enters the focusing structure 3 from the opening at the end of the sleeve 21 furthest from the output port 11. In this embodiment, the laser output beam undergoes only one reflection, reducing energy loss due to long-distance transmission, enhancing the energy density at the cutting point, and thus improving cutting efficiency.

[0046] Furthermore, the reflective structure 2 also includes an adapter plate 23 for connecting the radio frequency laser body 1 and the sleeve 21. There are two adapter plates 23, and each adapter plate 23 is provided with a through hole for the beam to pass through.

[0047] It should be noted that by setting the adapter plate 23 at the front end of the radio frequency laser body 1, the radio frequency laser body 1 and the sleeve 21 are connected. The adapter plate 23 is provided with a through hole for the beam to pass through, so that the laser beam emitted by the radio frequency laser body 1 can smoothly enter the sleeve 21 through the adapter plate 23.

[0048] In this embodiment, the adapter plate 23, the radio frequency laser body 1, and the sleeve 21 are all connected by screws. There are two adapter plates 23. However, in actual applications, there are no restrictions on the number, shape, specifications, and installation method of the adapter plates 23, as long as the above-mentioned technical effects can be achieved.

[0049] In the above embodiment, the focusing structure 3 includes a focusing tube and a focusing mirror. One end of the focusing tube is connected to one end of the sleeve 21. The other end of the focusing tube is a cut. The focusing mirror is located inside the focusing tube so that the light beam entering the focusing tube passes through the focusing mirror and exits from the cut.

[0050] Understandably, the light beam reflected by the sleeve 21 enters the condenser tube, is focused at the condenser lens inside the condenser tube, and finally exits from the cutting hole to cut the fabric.

[0051] In practical applications, a fume extraction device is installed directly below the cutting edge to extract the fumes generated during the cutting process and prevent them from affecting the condenser lens. This fume extraction device is not the focus of this application and will not be elaborated upon here, referring to existing technology.

[0052] Please refer to Figure 3 The focusing tube includes a fixed part 31, a mounting part 32, a connecting part 33 and a light-emitting part 34, which are coaxially arranged and connected in sequence. The fixed part 31, the mounting part 32 and the connecting part 33 are all cylindrical structures. The top of the fixed part 31 is located at the reflection outlet. The diameter of the mounting part 32 is larger than the diameter of the fixed part 31 and the connecting part 33. A focusing lens is provided inside the mounting part 32. The light-emitting part 34 is a conical structure and has a cut at the bottom.

[0053] It should be noted that the focusing tube is fixed to the front end of the radio frequency laser body 1 by the fixing part 31, and the mounting part 32 is used to mount the focusing lens. The diameter of the focusing lens is larger than the diameter of the fixing part 31 so that the beam passing through the fixing part 31 can be completely focused on the focusing lens. The beam passing through the focusing lens enters the connecting part 33 and finally exits from the cutting hole of the light emitting part 34.

[0054] In this embodiment, the outer periphery of the connecting part 33 is provided with an air blowing hole, which is connected to an air blowing device to blow away the smoke generated during the cutting process. The air blowing device is not the focus of this application, and will not be described in detail here, referring to the prior art.

[0055] In the above embodiments, the focusing structure 3 also includes a fixing base 35 for connecting the radio frequency laser body 1 and the focusing tube, and the fixing base 35 is an elastic structure.

[0056] It is understandable that by setting the fixing seat 35, the fixing part 31 of the focusing tube is fixed, thereby fixing the focusing tube to the front end of the radio frequency laser body 1.

[0057] In a preferred embodiment, the mounting base 35 has an L-shaped structure, the side plate of the mounting base 35 is connected to the radio frequency laser body 1, and the bottom plate of the mounting base 35 is provided with a slot for engaging the focusing tube.

[0058] It should be noted that the fixing base 35 is an elastic structure, and the bottom plate of the fixing base 35 is provided with a slot for engaging the focusing tube. The focusing tube is engaged through the slot and the position of the focusing tube is fixed by bolts.

[0059] Please refer to Figure 2 and Figure 4 The radio frequency laser body 1 and the template machine 10 are connected by at least three connecting plates 4. One of the connecting plates 4 is located near the front end of the radio frequency laser body 1, and the other two connecting plates 4 are located near the rear end of the radio frequency laser body 1, and are arranged vertically.

[0060] It is understandable that the connection between the radio frequency laser body 1 and the template machine 10 is achieved by setting multiple connecting plates 4. In this embodiment, the radio frequency laser body 1 and the template machine 10 are connected by three connecting plates 4. However, in actual applications, there are no restrictions on the number, specifications, shape, connection method, etc. of the connecting plates 4.

[0061] In summary, the radio frequency laser for template machines provided by this utility model does not require an additional water tank for cooling, thus increasing ease of use; the lifespan of the radio frequency laser itself is superior to that of a carbon dioxide laser; the structure of the radio frequency laser is relatively simple, without complex mechanical moving parts, resulting in relatively low maintenance costs; operation is relatively simple, processing parameters can be easily set, and the technical requirements for operators are relatively low.

[0062] Radio frequency (RF) lasers enable extremely precise cutting of fabrics, accurately replicating the designed template shape. They can perfectly cut complex curves and intricate patterns, ensuring the templates produced are dimensionally accurate in the next process, closely matching the desired product shape. This guarantees consistent dimensions across different batches of garments, improving product quality stability. Compared to traditional cutting methods, RF lasers offer significantly faster cutting speeds. They can rapidly melt and vaporize template material, quickly completing the cutting task. There's no need to replace cutting tools due to wear and tear; as long as the laser source is stable and the material supply is sufficient, cutting can continue continuously, making it suitable for mass production of templates. The rational structural layout and precise laser beam refraction, achieved through only one refraction point, reduce energy loss due to long-distance transmission, enhance the energy density at the cutting point, and reduce the need for manual focusing and adjustment, resulting in a smoother and faster cutting process. Integrating the PWM control system into the radio frequency laser: Through calibration and adjustment, changes in the duty cycle can accurately correspond to changes in laser power. This meets the requirements for fine power adjustment for cutting different fabrics. The calibration results are input into the system to provide a reserve technology for future intelligent identification of fabric thickness and material for automatic power adjustment.

For the structure of other parts of the template machine, please refer to the prior art, which will not be repeated here.

[0065] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0066] The above provides a detailed description of the radio frequency laser for a template machine and the template machine thereof provided by this utility model.
