Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a laser cutting device for medical device manufacturing. Background Technology

[0002] In the production of medical devices, laser cutting technology is widely used for cutting various parts due to its high precision, high efficiency, and non-contact processing characteristics. However, traditional laser cutting equipment still has some shortcomings in terms of functionality and environmental friendliness.

[0003] Firstly, in terms of material fixation, traditional laser cutting devices often use simple clamping or adsorption methods, which may be effective for small materials, but for larger or irregularly shaped materials, it is difficult to guarantee a stable fixation effect, thus affecting cutting accuracy and processing efficiency.

[0004] Secondly, regarding waste gas treatment, the waste gases generated during the production of medical devices often contain harmful substances. Direct release into the air not only pollutes the environment but may also threaten the health of operators. Traditional laser cutting equipment often lacks effective waste gas recovery and treatment mechanisms, failing to achieve environmental protection and sustainable development goals.

[0005] Furthermore, regarding cooling, laser cutting generates a significant amount of heat. If this heat is not dissipated promptly, it can not only affect the laser's performance and lifespan but also cause thermal damage to materials and the work platform. Traditional laser cutting equipment often employs simple air or water cooling methods, but these methods frequently suffer from poor heat dissipation and high energy consumption.

[0006] Therefore, a laser cutting device for medical device manufacturing is provided to solve the problems of high energy consumption and environmental pollution. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-14 The present invention provides a technical solution: a laser cutting device for medical device production, including a base 1; like Figure 1 As shown, in some embodiments, clamping components 6 are fixedly connected to both sides of the base 1. The clamping components 6 are used to clamp the material to be processed. A support column 2 is fixedly connected to the top of the base 1. A moving component 3 is fixedly connected to the top of the support column 2. A laser generator 4 is fixedly connected below the moving component 3. A collecting component 5 is fixedly connected below the moving component 3. The laser generator 4 is disposed in the collecting component 5. The collecting component 5 is used to collect impurities from the material to be processed.

[0018] like Figure 2 As shown, in some embodiments, the clamping assembly 6 includes a hydraulic cylinder 7. The fixing rod of the hydraulic cylinder 7 is fixed to the side of the base 1. A connecting column 8 is fixedly connected above the telescopic rod of the hydraulic cylinder 7. A hydraulic cylinder 9 is connected through the interior of the connecting column 8. The fixing rod of the hydraulic cylinder 9 is fixedly connected to the outside of the connecting column 8. The telescopic rod of the hydraulic cylinder 9 is connected through the connecting column 8 and is located inside the connecting column 8. A four-jaw chuck 10 is fixedly connected to the other end of the telescopic rod of the hydraulic cylinder 9. The four-jaw chuck 10 is used to clamp the material to be processed. By activating the hydraulic cylinder 9, the hydraulic cylinder 9 performs work to drive the four-jaw chuck 10 to move laterally. By activating the hydraulic cylinder 7, the hydraulic cylinder 7 performs work to drive the four-jaw chuck 10 to move longitudinally.

[0019] By activating hydraulic cylinder 29, the four-jaw chuck 10 can be moved horizontally; while by activating hydraulic cylinder 17, the entire connecting column 8 and the four-jaw chuck 10 can be moved vertically. This design allows the clamping assembly 6 to flexibly and accurately clamp and position the material to be processed.

[0020] like Figure 2-3As shown, in some embodiments, the moving component 3 includes a fixed plate 11, which is fixedly connected to the top of the support column 2. A hydraulic cylinder 3 12 is fixedly connected above the fixed plate 11. The fixed rod of the hydraulic cylinder 3 12 is fixedly connected to the fixed plate 11. A moving plate 13 is fixedly connected to the other end of the telescopic rod of the hydraulic cylinder 3 12. An electric guide rail 14 is fixedly connected below the moving plate 13. A sliding rod 15 is slidably connected to the electric guide rail 14. An electric guide rail 2 16 is fixedly connected to the side of the sliding rod 15.

[0022] like Figure 4 As shown, in some embodiments, a waste liquid collection assembly 39 is fixedly connected above the base 1. The waste liquid collection assembly 39 includes a storage tank 18 for storing waste liquid and is fixed above the base 1. A collection tank 19 is fixedly connected above the storage tank 18, and a liquid outlet 191 is provided at the bottom of the collection tank 19. A vacuum pump 20 is fixedly connected to the bottom of the collection tank 19, and the vacuum pump 20 is used to reduce the pressure inside the collection tank 19 (creating a negative pressure difference relative to the external environment). A working platform 21 is fixedly connected above the collection tank 19, and a plurality of drainage holes are provided on the working platform 21. These drainage holes penetrate the working platform 21 and are used to place materials to be processed.

[0023] After the material to be processed is placed on the work platform 21, the vacuum pump 20 is started. The vacuum pump 20 reduces the pressure inside the liquid collection tank 19, thereby creating a pressure gradient from the outside to the inside between the inside of the liquid collection tank 19 and the surface of the work platform 21. Due to the existence of this pressure gradient, the material to be processed comes into contact with the internal space of the liquid collection tank 19 through the drain hole of the work platform 21 and is firmly adsorbed onto the surface of the work platform 21.

[0024] During processing, the waste liquid generated is smoothly discharged into the collection tank 19 through the drain hole of the working platform 21, and then flows into the storage tank 18 for storage from the outlet hole 191 of the collection tank 19. This design not only ensures the effective collection of waste liquid, but also significantly improves the cleanliness and efficiency of the processing.

[0025] like Figure 5 and Figure 13 As shown, in some embodiments, a rotating assembly 40 is fixed to the outside of the collection tank 19.

[0027] like Figure 5 As shown, in some embodiments, a motor 32 is fixed to the outside of the base 1. The motor 32 includes a motor output shaft, on which a pulley 321 is fixed. A V-belt 31 is sleeved around the peripheral planetary gears and the pulley 321. When the motor 32 is started, the output shaft of the motor 32 rotates, which drives the peripheral planetary gears to rotate through the V-belt 31. This drives the planetary gears 30 and the screw 28 to rotate. The screw 28 drives the push plate 27 to move back and forth through threaded engagement. The push plate 27 drives the support rod 26 to rotate relative to the push plate 27. The support rod 26 drives the rotating platform 25 to rotate relative to the ear plate 23.

[0028] This design not only enables the flexible rotation of the rotating platform 25, but also achieves automated control of the entire rotating assembly 40 through the driving action of the motor 32.

[0029] like Figure 6-10 and Figure 13 As shown, in some embodiments, the collecting assembly 5 includes a collecting cover 501, which is fixedly connected to the bottom of the moving rod 17.

A wire channel 515 is provided on the outside of the brake rope 509, and the wire channel 515 is used to protect the brake rope 509.

[0036] The rotating platform 25 rotates upward, causing one end of the brake rope 509 to move upward. The other end of the brake rope 509 causes the slider 510 to slide downward relative to the collection cover 501. The slider 510 causes the push rod 508 to move downward.

The rotating rod 506 causes the fan frame 503 to rotate. The fan frame 503 rotates relative to the fan housing 505 at the point where the two are engaged. The fan frame 503 causes the electric blade 504 to rotate relative to the fan housing 505.

[0037] If the electric blades 504 are activated before the fan frame 503 rotates, the gas inside the collection shroud 501 will be discharged to the outside through the outlet 502. After the fan frame 503 rotates, if the electric blades 504 are activated again, the gas outside the collection shroud 501 will be discharged to the inside through the outlet 502.

[0038] When the rotating platform 25 rotates downward, the spring 511 drives the slider 510 to slide upward relative to the collection cover 501.

The cooling nozzle 38 is fixedly connected above the rotating platform 25.

[0041] When the laser generator 4 performs cutting operations, the electric blade 504 is activated. Under the influence of the airflow difference generated by the electric blade 504, the gas inside the collection hood 501 enters the filter 34 through the air outlet 502 and exhaust pipe. After being filtered by the filter 34, the filter residue and liquid in the gas enter the liquid collection tank 19. The gas filtered by the filter 34 then enters the thermogenerator 35 through the exhaust pipe. The thermogenerator 35 generates electricity to provide power to the rechargeable battery 36, which in turn provides power to the motor 32. The exhaust gas enters the waste gas collection device 37, where it is purified by adsorption, oxidation, and low-temperature plasma technology. After the gas is cut by the laser generator 4, the gas is cooled by the low temperature. The rotating platform 25 rotates by starting the motor 32, and the electric blades 504 rotate relative to the fan housing 505. The electric blades 504 and the cooling nozzle 38 are activated to spray out the purified and cooled gas. The gas sprayed from the air outlet 502 is used to cool the laser generator 4, while the gas sprayed from the cooling nozzle 38 is used to cool the materials and the working platform 21.

[0042] This design not only achieves effective filtration and purification of the gas, but also realizes energy recovery and utilization through the power generation function of the thermogenerator 35. At the same time, the cooling function of the cooling nozzle 38 ensures the normal operating temperature of the laser generator 4 and the working platform 25.

[0043] Example 1: In this example, laser cutting is performed by using the moving component 3 and the laser generator 4 to cut the material to be processed.

[0044] Specifically, the material to be processed is placed on the working platform 21. By activating the vacuum pump 20, the pressure difference between the inside and outside of the liquid collection tank 19 is changed. The material to be processed comes into contact with the internal space of the liquid collection tank 19 through the drain hole of the working platform 21 and is firmly adsorbed onto the surface of the working platform 21 under the force of the pressure difference. By changing the pressure inside the liquid collection tank 19, the material is fixed, thus achieving the purpose of fixing the material to be processed.

[0045] When the material to be processed is large, it comes into contact with the internal space of the liquid collection tank 19 through the drain hole of the working platform 21. Due to the pressure difference, it cannot be completely fixed to the surface of the working platform 21. By activating hydraulic cylinder 29, the four-jaw chuck 10 moves laterally. Similarly, by activating hydraulic cylinder 17, the four-jaw chuck 10 moves longitudinally. Once the four-jaw chuck 10 contacts the material, hydraulic cylinders 17 and 29 stop, and the four-jaw chuck 10 is activated. The jaws of the four-jaw chuck 10 retract to completely fix the material before stopping, further securing the material. By controlling the two four-jaw chucks 10, the material to be processed is fixed, achieving the purpose of further securing large materials.

[0046] By activating hydraulic cylinder three 12, the telescopic rod of hydraulic cylinder three 12 drives the moving plate 13, sliding rod 15, moving rod 17, and laser generator 4 to move up and down. By activating electric guide rail one 14, the sliding rod 15, moving rod 17, and laser generator 4 move back and forth. By activating electric guide rail two 16, the moving rod 17 and laser generator 4 move left and right. By activating laser generator 4, laser light is emitted to cut the material. By controlling hydraulic cylinder three 12, electric guide rail one 14, and electric guide rail two 16 to move laser generator 4 freely in three directions, the laser emitted by laser generator 4 cuts the desired shape on the material, achieving the purpose of material processing.

[0047] Example 2: In this example, the function of waste gas recovery is realized. The waste liquid collection component 39 is responsible for collecting the waste liquid generated during the material processing, while the collection component 5 focuses on the collection and utilization of waste gas, so as to achieve the purpose of not polluting the air and reusing the waste gas.

[0048] Specifically, the waste liquid generated during the processing is first discharged into the collection tank 19 through the drain hole of the working platform 21, and then flows into the storage tank 18 through the outlet hole 191 for storage or further processing.

[0049] By activating the electric blades 504, the heat and gas inside the collection hood 501, under the influence of the airflow velocity difference generated by the electric blades 504, enter the filter 34 through the air outlet 502 and the exhaust pipe. The filter 34 separates the filter residue and liquid in the gas. The filter residue and liquid enter the liquid collection tank 19, while the filtered gas continues to enter the thermogenerator 35 through the exhaust pipe. The thermogenerator 35 uses the heat energy in the waste gas to generate electricity, providing power to the rechargeable battery 36, thus realizing the secondary utilization of energy. The gas discharged from the thermogenerator 35 enters the waste gas collection device 37, where it is purified by adsorption, oxidation, and low-temperature plasma technology. The purified gas is stored in the waste gas collection device 37, ensuring that the emitted gas meets environmental protection standards, achieving the goal of green environmental protection and no air pollution.

[0050] Waste residue and waste gas generated during the operation of this device are collected through the liquid outlet 191 and the electric blades 504, achieving the purpose of waste gas and waste material collection. The filter 34 further separates the liquid and waste material in the waste gas, preventing liquid and solid in the waste gas from damaging the device in subsequent steps. The synergistic effect of the thermal generator 35 and the waste gas collection device 37 not only achieves the purification of waste gas but also realizes the secondary utilization of energy, embodying the concept of green environmental protection and sustainable development.

[0051] Example 3: This example achieves the cooling function for materials and the working platform 21. Purified gas is ejected through the electric blades 504 and cooling nozzles 38 to cool the materials and the working platform 21.

[0052] Specifically, when cooling of the work platform 21 is required, the motor 32 is started. The output shaft of the motor 32 is driven by the V-belt 31, causing the peripheral planetary gears to rotate, which in turn drives the planetary gears 30 and the screw 28 to rotate. The screw 28 is connected by a threaded engagement, pushing the push plate 27 to move back and forth. The movement of the push plate 27 causes the support rod 26 to rotate relative to it, which in turn causes the rotating platform 25 to rotate relative to the ear plate 23. When the rotating platform 25 rotates to a vertical position, the cooling nozzle 38 is precisely aligned with the surface of the work platform 21. At this time, the cooling nozzle 38 is activated to discharge the gas inside the exhaust gas collection device 37, cooling the work platform 21 and the material.

[0053] The rotating platform 25 rotates upward, causing one end of the brake rope 509 to move upward. The other end of the brake rope 509 causes the slider 510 to slide downward relative to the collection cover 501. The slider 510 causes the push rod 508 to move downward. The push rod 508 causes the positioning pin 507 to slide upward relative to the push rod 508. The push rod 508 causes the rotating rod 506 to rotate relative to the fan housing 505. The rotating rod 506 causes the fan frame 503 to rotate. The fan frame 503 rotates relative to the fan housing 505 at the point where the two are engaged. The fan frame 503 causes the electric blade 504 to rotate relative to the fan housing 505.

[0054] When the fan frame 503 rotates, the gas inside the exhaust gas collection device 37 is discharged through the air outlet 502 by activating the electric blades 504. The discharged gas is used to cool the laser generator 4.
