Description

Technical Field

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

[0002] In the garment manufacturing industry, laser template machines, as a highly efficient fabric processing device, are widely used in the fabric cutting process. Their working principle involves placing the fabric in a specific template, then placing and fixing the template onto the laser template machine, where a high-precision laser beam achieves accurate cutting of the fabric. This cutting method not only improves production efficiency but also ensures consistent cutting quality, thus gaining widespread application in the garment manufacturing industry.

[0003] The core components of a laser cutting device are the laser tube, the optical tube, and the reflector adjustment plate. These components work together to ensure that the laser beam accurately reaches the cutting head, achieving efficient and precise cutting results. However, existing laser cutting devices have a significant design flaw: gaps exist at the ends of the laser tube, the optical tube, and the reflector adjustment plate. These gaps allow tiny particles such as lint and dust from the surrounding environment to easily enter the internal structure of the laser device through airflow, readily adhering to the critical focusing lens. Due to the high energy density of the laser, the lint and dust adhering to the focusing lens are easily ignited after continuous laser irradiation. The resulting carbides and other substances further contaminate the focusing lens surface, causing it to blacken and ultimately damaging it.

[0004] Therefore, how to solve the problem of external impurities easily invading the interior of the laser cutting device 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.

[0029] It should be noted that the directional terms such as "inner" and "outer" in the following text are defined based on the accompanying drawings in the instruction manual.

[0030] The core of this invention is to provide a laser cutting device that comprehensively blocks the intrusion path of external impurities, fundamentally reducing dust contamination of the internal components of the laser cutting device. Another core aspect of this invention is to provide a template machine that includes the aforementioned laser cutting device, further reducing dust contamination of the laser cutting device.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 A laser cutting device includes a laser tube 10, a base 20, a reflector mounting base 30, an adjustment plate 40, a laser tube 50, and a condenser lens mounting base 60.

[0032] Specifically, the laser tube 10, the reflector mounting base 30, and the condenser lens mounting base 60 are all mounted on the base 20. The base 20 provides the mounting foundation for the laser tube 10, the reflector mounting base 30, and the condenser lens mounting base 60. The light-emitting end of the laser tube 10 is clearance-fitted with the end plate of the base 20. A first dustproof component 1 is provided between the light-emitting end of the laser tube 10 and the end plate to seal the gap between them. The first dustproof component 1 is used to seal the gap between the light-emitting end of the laser tube 10 and the end plate of the base 20 to prevent external impurities from entering the interior of the laser cutting device through the gap between the light-emitting end of the laser tube 10 and the end plate of the base 20. The adjusting plate 40 is mounted on the reflector mounting base 30 and clearance-fitted with it. A sealing mechanism is provided between the reflector mounting base 30 and the adjusting plate 40. A second dustproof component 2 is provided between the reflector mounting base 30 and the adjusting plate 40 to seal the gap between them, thereby preventing external impurities from entering the interior of the laser cutting device through the gap between the reflector mounting base 30 and the adjusting plate 40. The light tube 50 is located at the light-emitting end of the reflector mounting base 30, and the light-emitting end of the light tube 50 is clearance-fitted with the light-incident end of the condenser mounting base 60. A third dustproof component 3 is provided between the light-emitting end of the light tube 50 and the light-incident end of the condenser mounting base 60 to seal the gap between them, thereby preventing external impurities from entering the interior of the laser cutting device through the gap between the light-emitting end of the light tube 50 and the light-incident end of the condenser mounting base 60.

[0033] The first dustproof component 1, the second dustproof component 2, and the third dustproof component 3 all adopt a structure that is easy to install and replace. When maintenance or replacement of the dustproof components is required, operators can perform the operation quickly and conveniently without the need for complex disassembly and assembly of the entire laser cutting device, greatly saving maintenance time and labor costs. At the same time, because the dustproof structure effectively reduces the amount of dust entering the laser cutting device, it reduces the degree of contamination of the internal components of the laser cutting device, significantly reducing the daily maintenance workload of the laser cutting device, further reducing the maintenance cost of the laser cutting device, and improving the economy and practicality of the laser cutting device.

[0034] The laser cutting device configured in the above manner, by setting up a first dustproof component 1, a second dustproof component 2, and a third dustproof component 3, comprehensively blocks the intrusion path of external impurities, fundamentally reducing the contamination of the internal components of the laser cutting device by dust. By effectively preventing dust from entering the laser cutting device, the cleanliness of the optical components is ensured, allowing the laser to always be in a good focused state, thereby improving the precision and quality of laser cutting, ensuring the accuracy of the cutting dimensions and the smoothness of the cutting edges, and meeting the requirements of high-precision processing.

[0035] In the above embodiments, the first dustproof component 1, the second dustproof component 2, and the third dustproof component 3 are all flexible components.

[0036] Understandably, the first dustproof component 1, the second dustproof component 2, and the third dustproof component 3 are made of flexible materials, enabling them to tightly seal the gaps between the laser tube 10 and the end plate, precisely seal the gaps between the adjusting plate 40 and the reflector mounting base 30, and tightly seal the gaps between the optical tube 50 and the condenser lens mounting base 60. This creates a good seal between the laser tube 10 and the end plate, between the adjusting plate 40 and the reflector mounting base 30, and between the optical tube 50 and the condenser lens mounting base 60. This effectively prevents dust, lint, and other minute particles from entering the laser cutting device through the gaps between the laser tube 10 and the end plate, between the adjusting plate 40 and the reflector mounting base 30, and between the optical tube 50 and the condenser lens mounting base 60. Compared to rigid sealing materials, flexible dustproof components can better adapt to different shapes and sizes of the laser tube 10, adjusting plate 40, and optical tube 50. Even with minor unevenness or installation errors, they can maintain reliable sealing performance, significantly reducing the possibility of dust entering the laser cutting device and providing more effective protection for it.

[0037] Furthermore, during the operation of the laser cutting device, slight displacements may occur between the laser tube 10 and the end plate, between the adjusting plate 40 and the reflector mounting base 30, and between the optical tube 50 and the condenser lens mounting base 60 due to factors such as vibration or thermal expansion of the laser cutting device. The flexible nature of the dustproof components allows them to adapt to these slight vibrations and displacements without being damaged by rigid collisions or excessive stretching. This adaptability ensures the stability of the dustproof components during the operation of the laser cutting device, maintaining a good sealing effect even during long-term use. This prevents dust from entering the laser cutting device due to dynamic changes during operation, thereby improving the reliability and stability of the laser cutting device and reducing the risk of failure caused by dust contamination. In addition, while achieving a sealed dustproof environment, the dustproof components still maintain good heat dissipation, ensuring the stable operation and service life of the laser cutting device. The flexible nature of the dustproof components gives them good flexibility and operability, facilitating installation and replacement.

[0038] In the above embodiment, the first dustproof component 1 is a flexible dustproof sleeve. One end of the first dustproof component 1 is sleeved on the end of the laser tube 10, and the other end of the first dustproof component 1 abuts against the end plate of the base 20.

[0039] It should be noted that the dust cover of the laser tube 10 is installed between the laser tube 10 and the end plate. The inner wall of the dust cover is tightly attached to the outer wall of the laser tube 10, and the end face of the dust cover is tightly attached to the end plate. This can effectively prevent dust from entering the laser cutting device from the gap between the laser tube 10 and the end plate.

[0040] In the above case, the second dustproof component 2 is a dustproof ring, and the middle part of the adjusting plate 40 is provided with a convex ring, and the convex ring is provided with a groove for installing the dustproof ring.

[0041] Understandably, the reflector in a laser cutting device needs to be angled according to different cutting requirements to ensure precise reflection and focusing of the laser beam. Installing the dustproof ring in the groove of the adjustment plate 40 achieves both a sealing and dustproof function and does not obstruct the adjustment operation of the reflector, thus ensuring the normal operation of the laser cutting device and the adjustment of cutting accuracy.

[0042] Furthermore, the dust ring has a relatively simple and compact structure. It is installed in the groove of the adjustment plate 40, without occupying additional space or affecting the overall structural layout of the laser cutting device. At the same time, the installation and replacement of the dust ring are very simple. Operators only need to insert the dust ring into the groove to complete the installation, and replacement is as simple as removing the old dust ring and replacing it with the new one.

[0043] Furthermore, the third dustproof component 3 is a flexible dustproof sleeve. One end of the third dustproof component 3 is sleeved on the end of the optical tube 50, and the other end of the third dustproof component 3 abuts against the condenser lens mounting base 60.

[0044] It should be noted that the dust cover is installed between the optical tube 50 and the condenser lens mounting base 60. The inner wall of the dust cover is tightly attached to the outer wall of the optical tube 50, and the lower end of the dust cover is tightly attached to the condenser lens mounting base 60. This can effectively prevent dust from entering the laser cutting device from the gap between the optical tube 50 and the condenser lens mounting base 60.

[0045] In the above embodiment, the condenser lens mounting base 60 is provided with a condenser tube 50, and the condenser tube 50 is provided with a condenser lens.

[0046] Understandably, the condenser tube 50 provides a precise mounting position and stable support structure for the condenser lens, ensuring that the condenser lens maintains an accurate optical position and angle during operation. This effectively improves the focusing accuracy of the laser beam, enabling it to converge precisely at the cutting point, thereby significantly enhancing the precision and quality of laser cutting.

[0047] In a preferred embodiment, the focusing tube 50 includes a fixed part, a mounting part, a connecting part, and a light-emitting part that are coaxially arranged and connected in sequence. The fixed part, the mounting part, and the connecting part are all cylindrical structures. The diameter of the mounting part is larger than the diameter of the fixed part and the connecting part. A focusing lens is provided inside the mounting part, and the light-emitting part is a conical structure.

[0048] It should be noted that the condenser tube 50 is fixed to the end plate by the fixing part, and the mounting part is used to install the condenser lens. The diameter of the condenser lens is larger than the diameter of the fixing part so that the light beam passing through the fixing part can be completely focused on the condenser lens. The light beam passing through the condenser lens enters the connecting part and finally exits from the cutting hole of the light exiting part.

[0049] The mounting section has a larger diameter than the fixing and connecting sections, providing a stable and precise mounting position for the condenser lens. The condenser lens, installed within the mounting section, ensures the laser beam is precisely focused at a single point after passing through it, significantly improving focusing accuracy and thus enhancing the precision and quality of laser cutting. The beam exiting section employs a conical structure, effectively guiding the laser beam's propagation direction, reducing energy loss during propagation, and increasing laser energy utilization, thereby improving cutting efficiency. The coaxial arrangement of the fixing, mounting, connecting, and beam exiting sections ensures the consistency of the laser beam's optical path as it passes through the condenser tube 50, effectively reducing cutting errors caused by optical path deviation and ensuring the laser beam always propagates along the predetermined optical path, improving the stability of cutting precision and quality.

[0050] In the above case, the connecting part is provided with an air blowing hole that communicates with the interior, and the air blowing hole is connected to an air blowing device.

[0051] Understandably, the air blowing device continuously delivers clean gas (such as compressed air) to the surface of the condenser lens and the light-emitting part through the air blowing port. This can blow away tiny particles such as dust and lint in real time, preventing these impurities from adhering to the surface of the condenser lens and keeping it clean. This ensures that the laser beam is always in a good focused state, thereby improving the precision and quality of laser cutting. Moreover, operators do not need to frequently disassemble the condenser tube 50 for cleaning, saving maintenance time and labor costs.

[0052] Furthermore, the air blowing device can remove the heat and smoke generated during the cutting process, reducing the adverse effects of heat on the condenser lens, thus maintaining the stability and reliability of laser output and improving cutting efficiency. The use of the air blowing device enhances the operational reliability of the equipment in harsh environments, reduces malfunctions caused by environmental factors, and improves the stability and reliability of the equipment.

[0053] In the above embodiments, a smoking device is also included, which is located below the light-emitting part.

[0054] It should be noted that laser cutting generates a large amount of smoke and harmful gases. The fume extraction device removes the smoke from the cutting area, making the cutting area clearer and facilitating operator observation of the cutting process, thus improving accuracy and efficiency. Furthermore, the fume extraction device effectively reduces the chance of smoke entering the condenser tube 50, protecting optical components such as the condenser lens from contamination and extending their lifespan. This maintains the stability and reliability of the laser cutting device, ensuring the laser beam remains well-focused, thereby improving the precision and quality of laser cutting.

[0055] Furthermore, the heat carried in the cutting fumes can adversely affect optical components. The fume extraction device can effectively remove this heat, reducing heat accumulation and thus improving the operational stability and reliability of the laser cutting device, extending its service life. In dusty or harsh working environments, the fume extraction device can effectively remove fumes and harmful gases generated during the cutting process, reducing the impact of these pollutants on the laser cutting device and operators, thereby enhancing the operational reliability of the laser cutting device in harsh environments.

[0056] A template machine includes the aforementioned laser cutting device. The laser cutting device includes a base 20, a reflector mounting base 30, and a condenser lens mounting base 60. A laser tube 10 is housed within the base 20, with its light-emitting end fitting a clearance fit with the end plate of the base 20. One end of the reflector mounting base 30 is fixed to the end plate, and an adjustment plate 40 for adjusting the reflector angle is provided on the reflector mounting base 30. A light tube 50 is provided at the other end of the reflector mounting base 30, with its end fitting a clearance fit with the condenser lens mounting base 60. The condenser lens mounting base 60 is fixed to the base 20. By providing a first dustproof component 1, a second dustproof component 2, and a third dustproof component 3 between the laser tube 10 and the end plate, between the reflector mounting base 30 and the adjustment plate 40, and between the light tube 50 and the condenser lens mounting base 60, respectively, it is possible to comprehensively prevent dust, lint, and other minute particles from entering the critical areas inside the laser cutting device.

[0057] Through the synergistic effect of the first dustproof component 1, the second dustproof component 2, and the third dustproof component 3, dust contamination of optical components such as the focusing lens, reflecting lens, and condenser lens is effectively reduced, thereby significantly improving the dustproof performance of the device and ensuring the cleanliness and performance stability of the optical components. This is crucial for improving the precision and quality of laser cutting. For the structure of other parts of the template machine besides those disclosed in the above embodiments, please refer to the prior art; they will not be described in detail here.

[0058] In summary, the laser cutting device provided by this utility model, with the first dustproof component 1 sealing the gap between the laser tube 10 and the end plate, the second dustproof component 2 sealing the gap between the reflector mounting base 30 and the adjusting plate 40, and the third dustproof component 3 sealing the gap between the optical tube 50 and the condenser lens mounting base 60, comprehensively blocks the intrusion path of dust, fundamentally reducing the contamination of internal components by dust, thereby effectively reducing the risk of components being burned or damaged, extending the service life of key components such as the laser tube 10, reflector, and condenser lens, reducing the maintenance frequency and replacement cost of the laser cutting device, improving the reliability and stability of the laser cutting device, and ensuring the long-term efficient operation of the laser cutting device.
