Description

Technical Field

[0001] The invention belongs to the technical field of quartz tube processing equipment, and in particular relates to a large-caliber quartz tube laser cold cutting workstation. Background Art

[0002] With the development of modern industry, quartz tubes have been widely used as an important material in many fields, such as semiconductor manufacturing, optical fiber communications, chemical laboratory equipment, etc. The cutting quality of quartz tubes directly affects their application performance and subsequent processing efficiency. However, traditional cutting methods have certain limitations:

[0003] First, while conventional laser cutting can achieve high-precision processing, the instantaneous high temperature can easily lead to thermal stress concentration at the cut edge of the quartz tube, causing microcracks or edge collapse. This is especially true for large-diameter, thin-walled quartz tubes, where local overheating increases the risk of brittle fracture due to their low thermal expansion coefficient and poor thermal conductivity, seriously affecting the yield rate.

[0004] Secondly, the melt, debris and high-temperature oxidation products generated during the cutting process tend to adhere to the inner and outer walls of the quartz tube, requiring a secondary cleaning process;

[0005] In addition, in the existing technology, the inert gas protection and cooling systems are mostly designed separately, resulting in uneven airflow coverage and delayed cooling, which cannot effectively suppress incision oxidation and dust diffusion.

[0026] The technical effects achieved by the present invention are:

[0027] This invention achieves dynamic temperature control during the cutting process through an integrated protection mechanism. This mechanism utilizes a double-layered annular cavity. Cooling water flows into the inner layer, forming a curtain that directly absorbs heat from the cutting area and keeps the quartz tube surface temperature within a safe threshold. The outer layer sprays an inert gas (such as argon) to form an air curtain that isolates the oxygen environment. The synergistic effect of the cooling water and inert gas ensures uniform thermal stress distribution at the cut, preventing brittle fracture of the material due to localized overheating.

[0028] The present invention integrates the post-cutting cleaning process into the workstation through functional integration design, avoiding the tedious operation of secondary cleaning in traditional processes. The inner wall cleaning is completed by an auxiliary mechanism: the driving motor drives the first hollow rod to drive the water spray head and the air jet head to rotate, the high-pressure water flow flushes the molten material on the inner wall, and the gas blows away the residual water droplets; the linkage gear and the second ring gear are engaged and transmitted, so that the absorbent cotton of the outer wall cleaning mechanism rotates synchronously with the movement of the quartz tube to wipe the stains on the outer wall. In particular, the air supply part passes preheated air into the hollow shell, and accelerates the drying of the absorbent cotton through the through hole to maintain continuous adsorption capacity. This design improves the cleaning efficiency of the inner and outer walls without the need for human intervention, eliminating the risk of secondary contamination;

[0029] The present invention achieves efficient resource utilization through a closed-loop system.

The preheated air is respectively transported to the outer wall cleaning mechanism to form heat recovery. The combined action of inert gas and cooling water inhibits high-temperature oxidation reactions and reduces the generation of harmful gases. In addition, the pawl-ratchet mechanism realizes one-way transmission of the drive system, avoids interference from reverse airflow, ensures the coordinated operation of each module, reduces energy consumption, and is both economical and environmentally friendly.

[0055] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0057] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive of other embodiments.

[0058] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0059] Please see the attached Figures 1 to 15 As shown, this embodiment provides a large-caliber quartz tube laser cold cutting workstation, including a base 1;

[0060] Fixing mechanisms 2, both fixing mechanisms 2 are slidably connected to the base 1 and are used to fix the quartz tube to be processed;

[0061] Auxiliary mechanism 3, the auxiliary mechanism 3 is arranged at the right end of the base 1;

[0062] The cutting mechanism 4 is provided on the base 1 and is used for cutting the quartz tube;

[0063] The collecting trough 5 is provided on the base 1 and is used to collect waste generated by cutting;

[0064] The outer wall cleaning mechanism 6 is provided on the base 1 and is located to the right of the fixing mechanism 2, and is used to clean the outer wall of the quartz tube;

[0065] The protection mechanism 7 is provided on the cutting mechanism 4;

[0066] The auxiliary mechanism 3 includes a first support base 31 , on which a cleaning portion 32 is rotatably connected for cleaning or cooling the inner wall of the quartz tube. A driving mechanism 33 is provided on the base 1 , on which an air delivery portion 34 is provided.

[0067] Next, please refer to Figure 2 The fixing mechanism 2 includes a mounting seat 21, which is slidably connected to the base 1. A ring 22 is rotatably connected to the mounting seat 21 through a bearing. A fixing block 23 is fixedly connected to the ring 22 in an annular distribution. An electric push rod 24 is fixedly installed on the fixing block 23. The telescopic end of the electric push rod 24 is fixedly connected to a clamping block 26. The clamping block 26 is fixedly connected to a guide rod 25, and the guide rod 25 is slidably inserted into the fixing block 23. A first gear ring 27 is fixedly sleeved on the ring 22 of one of the mounting seats 21, and a rotating motor 28 is installed on this mounting seat 21. A transmission gear 29 is fixedly installed on the output shaft of the rotating motor 28.

[0068] In this embodiment, the quartz tube to be cut is sequentially inserted from the left into the two fixing mechanisms 2, then passed through the outer wall cleaning mechanism 6, ensuring that the end to be cut is located below the cutting mechanism 4. By synchronously controlling the extension of multiple electric push rods 24, multiple clamping blocks 26 are forced to approach each other, thereby securing the quartz tube to be cut. The rotary motor 28 is activated, driving the transmission gear 29 to rotate. The transmission gear 29 engages with the first ring gear 27, which in turn drives the ring 22 to rotate. The rotation of the ring 22 also drives the quartz tube fixed thereon. Furthermore, the guide rod 25 on the clamping block 26 is slidably connected to the fixing block 23, and the guide rod 25 serves as a limiter and guide.

[0069] It should be noted that the mounting seat 21 is slidably connected to the base 1, and a fastening bolt is provided on the mounting seat 21. By rotating the fastening bolt, the fastening bolt can be tightly abutted against the mounting seat 21 to fix the mounting seat 21 and prevent it from moving during the cutting process.

[0070] Secondly, please also refer to Figure 4 and Figure 5 The cutting mechanism 4 includes an XY biaxial moving mechanism 41 , which is fixedly mounted on the base 1 , and a laser head 42 is fixedly mounted on the XY biaxial moving mechanism 41 .

[0071] In this embodiment, a laser head 42 is connected to an external device. Through this laser head 42, the laser beam is precisely directed toward the quartz tube, enabling precise cutting of the tube. During the cutting process, a rotary motor 28 is used to continuously rotate the quartz tube to ensure uniformity and precision. This rotation enables the laser beam to comprehensively and evenly cut all sections of the tube, thereby improving cutting quality and efficiency.

[0072] To further enhance cutting precision and flexibility, the system is equipped with an XY biaxial motion mechanism 41. This allows for fine-tuning of the position of the laser head 42. The XY biaxial motion mechanism 41 utilizes a commercially available product. When selecting a model, consider the specifications and suitability of the application scenario, and try to select one that meets the requirements of this application. Specific specifications are not specified here.

[0073] Please refer again Figure 6 The protection mechanism 7 includes a disc 71, which is fixedly mounted on the laser head 42. Two annular cavities 72 are provided on the disc 71, and the lower ends of the annular cavities 72 are connected to nozzles 73 in an array arrangement. An air inlet pipe 75 and a water inlet pipe 74 are connected to the disc 71, and the air inlet pipe 75 is connected to the outer annular cavity 72, and the water inlet pipe 74 is connected to the inner annular cavity 72.

[0074] In this embodiment, we first need to connect the air inlet pipe 75 to the air inlet pipeline and then introduce an inert gas, such as argon. Next, we connect the water inlet pipe 74 to the water inlet pipeline to ensure smooth flow of cooling water. During the laser cutting process, the sprayed cooling water effectively cools the cutting area, effectively avoiding thermal stress caused by localized high temperatures and preventing microcracks in the cut quartz tube. Furthermore, the cooling water reduces the occurrence of high-temperature oxidation reactions, thereby suppressing the generation of harmful gases and ensuring the safety and environmental protection of the entire cutting process.

[0075] At the same time, the inert gas spray creates an air curtain that not only effectively isolates the air, preventing oxygen in the air from reacting with the cutting area, but also removes the heat generated during the cutting process, further reducing the temperature of the cutting area. Furthermore, this air curtain blocks water mist from splashing outward, preventing it from affecting the surrounding environment and equipment, ensuring a clean and efficient cutting process.

[0076] Next, please refer to Figure 4 and Figures 7 to 10The cleaning part 32 includes a first hollow rod 321, which is rotatably connected to the first support seat 31 through a bearing, and a driven gear 322 is fixedly installed on the outer wall of one end of the first hollow rod 321, and a second hollow rod 323 is fixedly connected to the interior of the first hollow rod 321. The outer wall of the other end of the first hollow rod 321 is connected to a nozzle head 324 in an annular distribution, and a water spray head 325 is fixedly connected to the nozzle head 324. The water spray head 325 is fixedly connected to a water pipe 326, and the other end of the water pipe 326 extends into the first hollow rod 321 and is connected to the second hollow rod 323. A water pump 327 is fixedly installed at one end of the base 1, and the water pumping end of the water pump 327 is connected to the nozzle head 324. The collecting tank 5 is connected, and the drainage end of the water pump 327 is fixedly connected to the drainage pipe 328. The drainage pipe 328 is a hard pipe, and the upper end of the drainage pipe 328 is rotatably connected to the second hollow rod 323 through a sealed bearing. The outer wall of the first hollow rod 321 is rotatably connected to the first hollow shell 329 through a sealed bearing. The first hollow rod 321 is provided with air holes 3210 distributed in a ring shape, and the air holes 3210 are located inside the first hollow shell 329. An air pump 3211 is fixedly installed on the base 1 through a bracket, and the exhaust end of the air pump 3211 is connected to the first hollow shell 329. The collecting tank 5 is provided with a filter frame at one end close to the water pump 327, and is located on the outside of the water pumping end of the water pump 327.

[0077] In this embodiment, the drain pipe 328 is rotatably connected to the second hollow rod 323, and the first hollow shell 329 is rotatably connected to the first hollow rod 321. When the first hollow rod 321 and the second hollow rod 323 rotate synchronously, the drain pipe 328 and the first hollow shell 329 do not rotate synchronously therewith.

[0078] Please refer again Figure 4 、 Figure 7 and Figure 8 The driving mechanism 33 includes a driving motor 331, which is fixedly connected to the bracket of the base 1. A driving rod 332 is fixedly connected to the output shaft of the driving motor 331, and the driving rod 332 is rotatably connected to the bracket on the base 1 through a bearing. A linkage gear 333 is installed at one end of the driving rod 332, and a driving gear 334 is installed at the other end of the driving rod 332.

[0079] In this embodiment, when performing a cutting operation, the drive motor 331 is first activated, causing it to rotate in the forward direction, thereby driving the drive rod 332. The rotation of the drive rod 332 drives the drive gear 334, which is connected to the driven gear 322 via a toothed belt drive, thereby rotating the first hollow rod 321. The rotation of the first hollow rod 321 also drives the jet head 324 and the water spray head 325 to rotate accordingly. Simultaneously, the water pump 327 is activated, drawing water from the collection tank 5. The water is then transported to the second hollow rod 323 via the drain pipe 328, and then to the water spray head 325 via the water pipe 326. Finally, the water is sprayed from the water spray head 325, where it cools and rinses the inner wall of the quartz tube. Because the water spray head 325 is tilted, the water is sprayed in the direction of the tilt, forcing the water to flow toward the cutting end and reducing the amount of wastewater entering the other end. In addition, the air pump 3211 is started to transport gas into the first hollow shell 329. The gas enters the first hollow rod 321 through the air hole 3210, then enters the nozzle 324 from the first hollow rod 321, and is finally ejected from the nozzle 324. The ejected gas is used to push the cooling water to move toward the cutting end of the quartz tube, further reducing the sewage at the other end.

[0080] It should be noted that the linkage gear 333 and the drive rod 332 are connected through a pawl-ratchet mechanism to achieve a one-way transmission function (such as Figure 15 Specifically, the linkage gear 333 is rotatably connected to the drive rod 332 via a bearing. A fixed ring is provided on the linkage gear 333, which is hingedly connected to the pawl. A return spring is provided between the pawl and the fixed ring. The drive rod 332 is fixedly mounted with a ratchet. The pawl-ratchet structure is well known in the art and will not be further described here.

[0081] Please refer again Figures 4 to 8 The air delivery part 34 includes a ventilation hood 341, which is rotatably connected to the driving rod 332 through a bearing, and the ventilation hood 341 is fixedly connected to the base 1 by a support rod, and the driving rod 332 is located at one end of the ventilation hood 341 and is equipped with a fan blade 342. The ventilation hood 341 is fixedly connected to a first air supply duct 343, and the upper end of the laser head 42 is fixedly sleeved with a hollow cylinder 344, and the hollow cylinder 344 is connected to the first air supply duct 343. The hollow cylinder 344 is also connected to a second air supply duct 345, wherein a part of the first air supply duct 343 and the second air supply duct 345 both adopt retractable hoses, and the rest adopts hard tubes.

[0082] In this embodiment, the drive rod 332 rotates, driving the fan blades 342. The rotation of the fan blades 342 draws external air into the ventilator 341. The air then flows through the first air supply duct 343 on the ventilator 341 and into the hollow cylinder 344 surrounding the laser head 42. The heat dissipated by the laser head 42 preheats the hollow cylinder 344. Simultaneously, the air flow helps cool the laser head 42, thereby reducing heat accumulation. The preheated air is then exhausted through the second air supply duct 345.

[0083] Please refer again Figures 11 to 14 The outer wall cleaning mechanism 6 includes a second support seat 61, which is fixedly connected to the base 1. The second support seat 61 is rotatably connected to a hollow column 62 through a bearing. A screw 63 is threadedly connected to the hollow column 62. One end of the screw 63 is rotatably connected to a placement box 64 through a bearing. The placement box 64 is inlaid with absorbent cotton 65. A slide rod 66 is fixedly connected to the placement box 64, and the slide rod 66 is slidably plugged into the hollow column 62. An annular groove is provided on the hollow column 62. 67, a second hollow shell 68 is rotatably connected to the hollow column 62 at the annular groove 67 through a sealed bearing, and the second hollow shell 68 is connected to the second air supply duct 345, a cavity 69 is opened on the placement box 64, and a through hole 611 is opened on the cavity 69, an air supply pipe 610 is connected to the placement box 64, and one end of the air supply pipe 610 is connected to the annular groove 67, and the other end is connected to the cavity 69, and a second gear ring 612 is fixedly sleeved on the outer wall of the hollow column 62.

[0084] In this embodiment, the second air supply duct 345 is connected to the second hollow shell 68, allowing preheated air to enter the interior of the second hollow shell 68 and then flow into the annular groove 67. The air then flows along the air supply duct 610 into the cavity 69, ultimately blowing air through the through hole 611 onto the absorbent cotton 65, accelerating its drying process and ensuring that the absorbent cotton 65 maintains good water absorption performance, thereby improving the cleaning efficiency of the outer wall of the quartz tube.

[0085] After the quartz tube is cut, the cutting mechanism 4 and the rotary motor 28 are turned off, stopping the rotation and cutting of the quartz tube. The rotating screw 63 causes the placement box 64 to translate, driving the absorbent cotton 65 to fit tightly against the outer wall of the quartz tube. The fastening bolt on the mounting base 21 is loosened to release its retaining function. The drive motor 331 is controlled to reverse, driving the drive rod 332 to rotate in the opposite direction, synchronously driving the first hollow rod 321 and the linkage gear 333 to rotate. At this point, the water pump 327 is turned off, and the air pump 3211 is activated separately, causing gas to continuously eject from the nozzle 324. The mounting base 21 is then pulled, driving the quartz tube away from the cutting mechanism 4. As the quartz tube moves, the continuously ejected gas dissipates any remaining water droplets inside, eliminating the need for manual cleaning of the inner wall of the quartz tube. Simultaneously, the first hollow rod 321 continuously drives the water nozzle 325 to rotate, ensuring that any water droplets on the inner wall of the quartz tube are completely removed.

[0086] The linkage gear 333 meshes with the second ring gear 612. Rotation of the linkage gear 333 drives the hollow column 62 in synchronous rotation. This rotation of the hollow column 62 causes the absorbent cotton 65 mounted on its surface to move circumferentially along the outer wall of the quartz tube. As the quartz tube moves axially, the absorbent cotton 65 wipes away any water adhering to its outer wall. This structure, through the circumferential coverage of the absorbent cotton 65, ensures comprehensive cleaning of the outer wall of the quartz tube, thereby improving product quality.

[0087] The working principle of the present invention is:

[0088] First, the quartz tube to be cut is secured between two fixing mechanisms 2 that are slidably connected to the base 1. A rotating motor 28 drives a transmission gear 29 that meshes with the first ring gear 27, causing the quartz tube to rotate. A cutting mechanism 4 precisely controls the laser beam to cut the rotating quartz tube. An XY biaxial motion mechanism 41 allows for fine-tuning of the position of the laser head 42 to ensure cutting accuracy. An auxiliary mechanism 3 cleans and cools the inner wall of the quartz tube. Air pump 3211 and water pump 327 supply air and water to clean waste generated during the cutting process, minimizing thermal stress damage. A protective mechanism 7 protects the cut area with inert gas and cooling water to prevent oxidation and cracking. An outer wall cleaning mechanism 6 removes residue from the outer wall of the quartz tube, enhancing product cleanliness. Throughout the entire process, a collection tank 5 collects waste generated by cutting, ensuring a clean and safe operating environment at the workstation.

[0089] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
