Description

Technical Field

[0001] This application relates to the technical field of laser cutting machines, and in particular to a dual-platform automated laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser emitted from a laser source to focus a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] When laser cutting machines cut batches of sheet metal, they can use a dual-platform system for loading and unloading. This allows one sheet metal to be loaded and cut while the other is unloaded and disassembled, improving the efficiency of batch sheet metal cutting. In addition, to ensure the cutting quality of the sheet metal, the laser cutting machine must clamp and adjust the tilt of the sheet metal before cutting to ensure that the sheet metal is firmly installed and that the laser beam of the laser cutting head is perpendicular to the sheet metal.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Currently, when switching between dual platforms for loading and unloading sheet metal, operators still need to disassemble and adjust the tilt of the wedge-shaped sheet metal during the process. This requires operator intervention during loading and unloading. When switching between dual platforms, the machine needs to be stopped while operators clamp and level the sheet metal. As a result, when one platform finishes cutting, the other platform may not be able to be positioned in time due to operator delays, leading to the laser cutting head being idle, interrupting continuous sheet metal processing, and thus affecting sheet metal production efficiency. Furthermore, operators are prone to errors when continuously disassembling and adjusting batches of sheet metal, which cannot guarantee the quality of batch sheet metal production. After laser cutting, the clamping parts are still in a high-temperature state, and operators are prone to burns when disassembling sheet metal, which cannot guarantee operator safety. Summary of the Invention

[0005] To address the issue that current dual-platform automated laser cutting machines require operators to disassemble and adjust the tilt of wedge-shaped plates during the switching between loading and unloading, this application provides a dual-platform automated laser cutting machine.

[0006] This application provides a dual-platform automated laser cutting machine using the following technical solution:

[0007] A dual-platform automated laser cutting machine includes a cutting table, a translation component for reverse translation of two angle steels, an adjustment component for horizontal adjustment, automatic disassembly and assembly, and water cooling of the angle steels, a disassembly and assembly component and a cooling component, a cutting head for laser cutting the angle steels, and a moving component for adjusting the position of the cutting head.

[0008] The translation assembly includes two worktables movably mounted on the cutting table and a translation component for translating the two worktables in opposite directions.

[0009] The adjustment assembly includes a movable table hinged to two workbenches respectively, and an adjustment component for adjusting the angle of the movable table.

[0010] The disassembly and assembly assembly includes a fixed clamping block fixed to two movable platforms, a movable clamping block movably disposed on two movable platforms, and a disassembly and assembly component for translating and driving the movable clamping block.

[0011] The cooling assembly includes two atomizing nozzles fixed on the cutting table, a filter membrane plate movably disposed on the cutting table, a water storage component for storing water in the two atomizing nozzles, an opening and closing component for periodically opening and closing the atomizing nozzles, and a filter component for filtering the liquid.

[0012] By adopting the above technical solution, metal sheets usually need to be cooled with liquid during laser cutting. In order to save the use of coolant, the liquid needs to be recycled. During the laser cutting of metal sheets, the debris usually produces oil stains mixed in the liquid, which can easily clog the filter membrane of the liquid recycling filter. However, the existing technology is not convenient to adsorb and separate the oil stains in the liquid during liquid filtration, which will affect the filtration time of the filter membrane, resulting in low processing efficiency and affecting the quality of the liquid. The laser beam of the cutting head is not perpendicular to the surface of the steel plate, which can easily cause uneven energy distribution of the laser beam, resulting in problems such as rough cutting surface, slag residue and burrs.

[0013] The translation component allows for switching and translating two angle steels, enabling simultaneous loading and unloading to accelerate batch processing. During loading and unloading, the adjustment component adjusts the angle of the angle steel, ensuring its top is perpendicular to the cutting head. The assembly and disassembly component automatically assembles and disassembles the angle steel during loading and unloading, preventing displacement during processing. During laser cutting, the cooling component cools the angle steel to prevent expansion, deformation, or warping due to high temperatures, ensuring cutting quality. The cooling component also includes a filter membrane plate. It can filter liquids and debris, and can recycle liquids to reduce resource waste. It can also precisely control the opening time of liquids and cleaning agents during the loading and unloading of angle steel, which can save on the cost of using liquids and cleaning agents, speed up the filtration time of the filter membrane, and minimize the clogging of the filter membrane. At the same time, it can save the operator's operation steps, eliminating the need to disassemble and assemble the angle steel, adjust its level, and turn on and off the liquid and cleaning agent before loading and unloading the angle steel. This can ensure the processing time of batch angle steel and save the operator's operation steps during the laser cutting of angle steel.

[0014] Optionally, the translation component includes two threaded rods rotatably mounted on the cutting table, two first bevel gears and two second bevel gears, and a bidirectional motor fixed on the cutting table. The two first bevel gears are respectively fixedly connected to the two output shafts of the bidirectional motor, the two first bevel gears are respectively meshed with the two second bevel gears, the two second bevel gears are respectively fixedly connected to the two threaded rods, and the two threaded rods are respectively threadedly connected to the two worktables.

[0015] By adopting the above technical solution, the translation component can switch and translate the two worktables. The bidirectional motor can drive the two first bevel gears, the two second bevel gears and the two threaded rods to rotate respectively, which can drive the two worktables and the two movable tables to translate back and forth respectively. The two movable tables will move forward and backward respectively, which can achieve the purpose of loading and unloading two angle steels at the same time, saving the loading and unloading time when cutting a batch of angle steels.

[0016] Optionally, the adjusting component includes electric push rods respectively hinged to two worktables and two distance sensors fixed to the cutting head. The two electric push rods are respectively hinged to the two movable tables, and the two distance sensors are electrically connected to the electric push rods.

[0017] By adopting the above technical solution, the adjustment component can adjust the inclination of the angle steel, the electric push rod can drive the movable table to swing at an angle, and when the angle steel moves below the cutting head, the two distance sensors can detect the inclination of the angle steel. When the distance measured by the two distance sensors is consistent, the electric push rod can be driven to stop driving, ensuring that the cutting surface of the angle steel is perpendicular to the laser cutter, thus ensuring the quality of the angle steel cutting.

[0018] Optionally, the assembly / disassembly components include electric telescopic rods fixed to two movable platforms, movable blocks fixed to the two electric telescopic rods, telescopic springs and sensors fixed to the two movable blocks, two movable clamping blocks slidably connected to the two movable blocks, two movable clamping blocks and two fixed clamping blocks movably fitting with two angle steels, two sensors movably fitting with the two movable clamping blocks, two sensors electrically connected to the two electric telescopic rods, and two telescopic springs fixedly connected to the two movable clamping blocks.

[0019] By adopting the above technical solution, the disassembly and assembly parts can automatically disassemble and assemble the angle steel. The electric telescopic rod can sequentially drive the movable block, sensor, telescopic spring and movable clamping block to move. The movable clamping block, together with the fixed clamping block, can clamp and fix the angle steel. When the movable clamping block is in contact with the angle steel, it will squeeze the telescopic spring, so that the movable clamping block is in contact with the sensor, indicating that the angle steel is currently in a clamped state. The sensor will drive the electric telescopic rod to stop driving. It can automatically clamp angle steel of different sizes and angles.

[0020] Optionally, the water storage device includes a water pump, a water pumping pipe, and a three-way pipe fixed on the cutting table. The water pumping pipe is connected to the inlet of the water pump, one inlet of the three-way pipe is connected to the outlet of the water pump, and the two atomizing nozzles are respectively connected to the other two outlets of the three-way pipe.

[0021] By adopting the above technical solution, the water storage component can spray liquid for cooling during laser cutting of angle steel. The water pump can sequentially draw the liquid in the cutting table into the water pipe, the three-way pipe and the atomizing nozzle. Then, the atomizing nozzle can spray the liquid onto the angle steel, which can cool the angle steel when the cutting head is laser cutting it, and prevent the angle steel from deforming due to excessive temperature during cutting.

[0022] Optionally, the opening and closing component includes two control valves respectively fixed to two atomizing nozzles, connecting gears respectively fixed to the two control valves, and fixed short teeth respectively fixed to two worktables, wherein the two fixed short teeth respectively mesh with the two connecting gears.

[0023] By adopting the above technical solution, the opening and closing components control the opening of the two atomizing nozzles at regular intervals. When the worktable moves, it also drives the fixed short tooth to move. When the angle steel moves to the processing position, the fixed short tooth will mesh with the connecting gear, and the rotation of the connecting gear will open the control valve. Then, the liquid in the three-way pipe can flow into the atomizing nozzle and spray the liquid onto the angle steel. At the same time, when the angle steel is cut and leaves the processing position, the fixed short tooth can rotate the connecting gear to close the control valve, which can stop the current liquid delivery and avoid liquid waste.

[0024] Optionally, the filter element includes movable scrapers fixed on two workbenches respectively, both of which are movably connected to the filter membrane plate, and the cutting table is provided with a cleaning element for adding chemicals to clean the filter membrane plate.

[0025] By adopting the above technical solution, the filter element can filter and separate the debris and liquid generated during the cutting of angle steel. The debris generated during the cutting of angle steel can be flowed onto the filter membrane plate by the spraying of liquid, which can filter and separate the liquid and debris. The liquid can be recycled. At the same time, when the two worktables are switched, they can also drive the two movable scrapers to move. When the two movable scrapers move, they can scrape the filter membrane plate and push the debris on the filter membrane plate, so as to avoid the debris accumulating in one position on the filter membrane plate and causing blockage.

[0026] Optionally, the cleaning component includes two medicine storage tanks fixed on the cutting table, medicine outlet pipes respectively connected to the two medicine storage tanks, and a discharge component for timed opening of the medicine outlet pipes, with both medicine outlet pipes located above the filter membrane plate.

[0027] By adopting the above technical solution, the cleaning component can spray cleaning agent onto the filter membrane plate for cleaning. The cleaning agent in the storage tank flows onto the filter membrane plate through the outlet pipe. With the addition of cleaning agent and the spraying of liquid, the filter membrane plate can be cleaned while the movable scraper is scraping it, thus minimizing the risk of the filter membrane plate being stuck and blocked by oil stains.

[0028] Optionally, the discharge component includes compression springs fixed to two discharge pipes, double-sided inclined blocks fixed to two compression springs, dosing plates fixed to two double-sided inclined blocks, and protrusions fixed to two workbenches, with the two protrusions movably engaging with the inclined surfaces of the two double-sided inclined blocks.

[0029] By adopting the above technical solution, the discharge component can control the timed opening of the dispensing pipe. When the worktable moves, it will drive the protrusion to move. When the protrusion is in contact with the double-sided inclined block, it will squeeze the compression spring, which will drive the double-sided inclined block and the dosing plate to move in sequence, thus opening the dispensing pipe. When the protrusion separates from the double-sided inclined block, the elastic force of the compression spring can restore the double-sided inclined block and the dosing plate to their original state, thus closing the dispensing pipe. The dispensing pipe can be briefly opened during the worktable switching process, allowing the cleaning agent in the storage tank to flow onto the filter membrane plate.

[0030] Optionally, the moving component includes an intelligent push rod fixed to the cutting head, a support block fixed to the intelligent push rod, a movable screw rotatably mounted on the cutting table, and a servo motor fixed to the cutting table. The movable screw is fixedly connected to the output shaft of the servo motor, and the movable screw is threadedly connected to the support block.

[0031] By adopting the above technical solution, the moving part can adjust the position of the cutting head, the intelligent push rod can drive the cutting head to move up and down, control the distance between the cutting head and the angle steel, and the servo motor can drive the movable screw to rotate, which in turn can drive the support block, the intelligent push rod and the cutting head to move in sequence, so that the cutting head can cut the angle steel.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The translation component allows one movable table to move below the cutting head while the other movable table moves to the starting position of the cutting table, thus achieving rapid loading and unloading of angle steel. After one angle steel is welded, the cutting head can immediately cut another loaded angle steel, saving loading and unloading time and improving the efficiency of batch welding. The assembly component can automatically clamp and fix the angle steel when the worktable moves the angle steel to load, preventing the angle steel from shifting during laser cutting and ensuring the welding effect. At the same time, it can automatically clamp angle steel of different sizes and angles, increasing the processing range of angle steel.

[0034] 2. The adjusting component can adjust the angle of the movable table and detect the inclination of the angle steel to ensure that the cutting surface of the angle steel is perpendicular to the laser cutter. This prevents the cutting head from easily shifting the focus when cutting the angle steel, avoids changes in the distance between the laser focus and the angle steel surface due to the angled surface of the angle steel, which would cause energy attenuation, and minimizes the phenomenon of the cut being wider at the top and narrower at the bottom, thus ensuring the quality of the angle steel cutting. The moving component can control the distance between the cutting head and the angle steel and can also drive the cutting head to move horizontally, so that the cutting head can cut the angle steel. After the angle steel is cut, the adjusting component can restore the movable table to its initial horizontal state to prevent the angle steel from slipping due to the tilt of the movable table during disassembly. At the same time, when the cut angle steel is unloaded, the disassembly component can automatically disassemble the angle steel. After the movable table is moved to the initial state, the operator can directly pick up and unload the angle steel.

[0035] 3. The water storage unit sprays liquid onto the angle steel, cooling it during laser cutting to prevent deformation due to overheating and ensure cutting quality. When the angle steel moves to the processing position, the opening and closing mechanism sprays liquid onto it, further cooling the cutting head. Liquid delivery stops when the angle steel leaves the processing position. The system automatically controls the opening and closing of two atomizing nozzles during switching between two worktables, precisely controlling their operation based on angle steel loading and unloading times. This eliminates the need for manual operation and electronic calculations, preventing liquid waste and reducing operator steps, thus improving batch processing time.

[0036] 4. The filter element can adsorb oil stains and filter and separate liquids and debris, facilitating liquid recycling and reducing water waste. During the transition between the two worktables, it can push debris on the filter membrane plate, preventing it from accumulating and clogging, thus accelerating filtration. The cleaning element, in conjunction with the discharge element, can briefly open the discharge pipe during worktable switching, allowing cleaning agent to flow onto the filter membrane plate. The addition of cleaning agent, combined with liquid spraying, cleans the filter membrane plate while the moving scraper brushes it, minimizing clogging due to oil stains. This further accelerates the filtration speed of liquids and debris. No manual control of the discharge pipe's opening time or electronic calculation is required, preventing cleaning agent waste. Automatic control during angle steel loading and unloading further reduces operator steps and shortens batch processing time. Attached Figure Description

It can automatically drive the water pump 23 when the cutting head 34 starts and automatically turn off the water pump 23 when the cutting head 34 closes. The two sensors 15 are electrically connected to the two electric push rods 13 respectively.

[0057] The implementation principle of a dual-platform automated laser cutting machine according to an embodiment of this application is as follows:

[0058] (1) The bidirectional motor 2 can drive the two first bevel gears 3, the two second bevel gears 4 and the two threaded rods 5 to rotate, which in turn can drive the two worktables 6 and the two movable tables 7 to move forward and backward respectively. The two movable tables 7 will move forward and backward respectively, so that the two movable tables 7 can be loaded and unloaded respectively. When one movable table 7 moves to the bottom of the cutting head 34, the other movable table 7 will move to the starting position of the cutting table 1 to complete the purpose of fast loading and unloading of angle steel 8. After one angle steel 8 is welded, the cutting head 34 can immediately cut the other loaded angle steel 8, which can save the loading and unloading time of angle steel 8 and improve the efficiency of batch welding of angle steel 8.

[0059] (2) Place the angle steel 8 on the movable table 7. When the worktable 6 drives the angle steel 8 to be fed, the electric telescopic rod 10 can sequentially drive the movable block 11, sensor 15, telescopic spring 14 and movable clamping block 12 to move. When the movable clamping block 12 is in contact with the angle steel 8, it can be clamped and fixed with the fixed clamping block 9 to avoid the angle steel 8 from shifting during laser cutting and to ensure the welding effect of the angle steel 8. When the movable clamping block 12 is in contact with the angle steel 8, the movable clamping block 12 will squeeze the telescopic spring 14 to make the movable clamping block 12 in contact with the sensor 15, indicating that the angle steel 8 is currently in a clamped state. Then the sensor 15 will drive the electric telescopic rod 10 to stop driving to prevent the movable clamping block 12 from moving continuously. In this way, angle steel 8 of different sizes and angles can be automatically clamped to improve the processing range of angle steel 8.

[0060] (3) At the same time, when the angle steel 8 is clamped, the sensor 15 will also drive the electric push rod 13 to level the angle steel 8. Since the worktable 6 and the movable table 7 are both hinged to the electric push rod 13, and the worktable 6 is hinged to the movable table 7, the electric push rod 13 can drive the movable table 7 to swing at an angle. When the angle steel 8 moves below the cutting head 34, the tilt of the angle steel 8 can be detected by the two distance sensors 35. When the distances measured by the two distance sensors 35 are inconsistent, the electric push rod 13 can continue to adjust the angle of the movable table 7 until the distances measured by the two distance sensors 35 are consistent. Then the electric push rod 13 can be driven to stop driving, ensuring that the cutting surface of the angle steel 8 is perpendicular to the laser cutter, avoiding the easy occurrence of focus shift when the cutting head 34 cuts the angle steel 8, avoiding the change in the distance between the laser focus and the surface of the angle steel 8 caused by the angled surface of the angle steel 8, causing energy attenuation, and minimizing the phenomenon of the cut of the angle steel 8 being wider at the top and narrower at the bottom, thus ensuring the quality of the angle steel 8 cutting.

[0061] (4) The intelligent push rod 33 can drive the cutting head 34 to move up and down, control the distance between the cutting head 34 and the angle steel 8, and drive the movable screw 31 to rotate through the servo motor 30, which in turn can drive the support block 32, the intelligent push rod 33 and the cutting head 34 to move in sequence, so that the cutting head 34 can cut the angle steel 8.

[0062] (5) After the angle steel 8 is cut, the electric push rod 13 can restore the movable table 7 to the initial horizontal state to prevent the angle steel 8 from slipping due to the tilt of the movable table 7 during disassembly. When the worktable 6 and the movable table 7 move forward, the angle steel 8 can be unloaded to prepare for the loading of the next angle steel 8. During the unloading process, the movable block 11 and the movable clamping block 12 can be restored to the initial state by the electric telescopic rod 10, which can automatically disassemble the angle steel 8. After the movable table 7 moves to the initial state, the staff can directly pick up and unload the angle steel 8.

[0063] (6) The liquid in the cutting table 1 can be sequentially pumped into the pumping pipe 37, the three-way pipe 24 and the two atomizing nozzles 25 by the water pump 23. Then the atomizing nozzles 25 can spray the liquid onto the angle steel 8. The angle steel 8 can be cooled when the cutting head 34 performs laser cutting on the angle steel 8, so as to avoid the angle steel 8 from deforming due to excessive temperature during cutting and ensure the quality of the angle steel 8 cutting.

[0064] (7) When the workbench 6 moves, it will also drive the fixed short tooth 28 to move. When the angle steel 8 moves to the processing position, the fixed short tooth 28 will mesh with the connecting gear 27 and make the connecting gear 27 rotate so that the control valve 26 can be opened. Then the liquid in the three-way pipe 24 can flow into the atomizing nozzle 25 and spray the liquid onto the angle steel 8, so that the cutting head 34 can cool the angle steel 8 when cutting it. At the same time, when the angle steel 8 is cut and leaves the processing position, the fixed short tooth 28 can make the connecting gear 27 rotate so that the control valve 26 can be closed, so as to stop the current liquid delivery and avoid liquid waste. In this way, the opening and closing of the two atomizing nozzles 25 can be automatically controlled during the switching of the two workbench 6. According to the loading and unloading time of the angle steel 8, the opening and closing time of the two atomizing nozzles 25 can be accurately controlled. The operator does not need to manually open and close the liquid to control the opening time, nor does the operator need to calculate the opening time through electrical control. First, liquid waste can be avoided. Second, the operation steps of the operator can be reduced and the batch processing time of the angle steel 8 can be increased.

[0065] (8) By spraying the liquid, the debris generated during the cutting of angle steel 8 can flow along the liquid to the filter membrane plate 16. The liquid will flow through the filter membrane plate 16 to the inner bottom wall of the cutting table 1, while the debris will remain above the filter membrane plate 16. At the same time, the oil stains can be adsorbed, and the liquid and debris can be filtered and separated, so as to facilitate the recycling of the liquid and reduce the waste of resources. When the two worktables 6 are switched, the two movable scrapers 17 can also be moved. When the two movable scrapers 17 move, they can scrape the filter membrane plate 16, and push the debris on the filter membrane plate 16, so as to avoid the debris from accumulating in one position on the filter membrane plate 16 and causing blockage, and speeding up the filtration time of the filter membrane plate 16.

[0066] (9) When the worktable 6 moves, it also drives the protrusion 29 to move. When the protrusion 29 is in contact with the double-sided inclined block 20, it squeezes the compression spring 22, which in turn drives the double-sided inclined block 20 and the dosing plate 21 to move. The dosing plate 21 can move into the groove in the dispensing tube 19, thereby opening the dispensing tube 19. When the protrusion 29 separates from the double-sided inclined block 20, the elastic force of the compression spring 22 can restore the double-sided inclined block 20 and the dosing plate 21 to their original state. The dosing plate 21 moves out of the groove, which can close the dispensing tube 19. Thus, by this method, the dispensing tube 19 can be briefly opened during the switching of the worktable 6, which can make The cleaning agent in the storage tank 18 flows to the filter membrane plate 16 through the outlet pipe 19. With the addition of the cleaning agent and the spraying of liquid, the filter membrane plate 16 is cleaned when the movable scraper 17 scrapes it, which can prevent the filter membrane plate 16 from being stuck and blocked by oil stains. This can further accelerate the filtration speed of the filter membrane plate 16 for liquid and debris. There is no need for the staff to manually open and close the outlet pipe 19 to control the opening time, nor is there a need to calculate the opening time through electrical control, which can avoid the waste of cleaning agent. It can be automatically controlled when the angle steel 8 is loaded and unloaded, which can further reduce the number of steps for the staff to operate and shorten the batch processing time of the angle steel 8.

[0067] (10) Compared with the prior art, when switching between the two platforms to load and unload the angle steel 8, the staff does not need to manually disassemble and install the wedge-shaped angle steel 8 and adjust its inclination. This reduces the number of steps that the staff need to take when loading and unloading the angle steel 8. When switching between the two platforms, the machine does not need to be stopped to clamp and level the angle steel 8. This can reduce the interruption time during batch processing of angle steel 8, reduce the idle time of the cutting head 34, improve the production efficiency of angle steel 8, avoid errors caused by disassembly and adjustment during batch processing of angle steel 8, and prevent the clamping parts and angle steel 8 from being in a high temperature state after laser cutting, thus ensuring the safety of the staff.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
