Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, specifically to a laser cutting machine tool that is easy to clean. Background Technology

[0002] When a laser cutting machine is operating, a high-energy laser beam instantly melts or vaporizes a localized area of ​​the metal sheet. Assist gas then blows the molten material away, creating a cut. During this process, some molten metal splashes and re-solidifies, adhering to the sides of the spiked support strips (also known as "sword grids") used to support the sheet, forming hard slag. This slag buildup raises the sheet, causing uneven support and severely affecting the accuracy and quality of subsequent cuts. It can even scratch the bottom of the sheet or interfere with the cutting head's operation.

[0003] To maintain machining accuracy, molten slag must be cleaned regularly. Traditional manual cleaning methods are inefficient, labor-intensive, and pose safety hazards. Therefore, existing technologies have developed solutions that integrate the cleaning function into the machine tool. For example, Chinese utility model patent CN221337126U discloses a laser cutting machine with a slag-removing structure. This solution features an independent cleaning frame on one side of the machine tool, on which a liftable cleaning plate is mounted. The lower edge of the cleaning plate has a notch that mates with the spike support bars. During cleaning, a cylinder drives the cleaning plate to descend, causing the notch to engage with the spike support bars. Then, the entire cleaning frame moves along the length of the worktable, using the side of the cleaning plate to scrape the side of the spike support bars, thereby removing the molten slag.

[0004] However, it suffers from a fundamental technical flaw: its cleaning action relies entirely on the overall translational movement of the cleaning frame, achieving cleaning through rigid scraping between the cleaning plate and the molten slag and spiked support bars. This cleaning method primarily leads to the following problems: The cleaning process involves high resistance, high energy consumption, and a heavy burden on the drive mechanism: the molten slag bonds firmly to the metal matrix, becoming even harder after repeated thermal cycles. Pure translational scraping requires a tremendous positive force to overcome the slag's adhesion. This not only leads to a higher drive power requirement and increased energy consumption during the cleaning process, but also places higher demands on the strength and durability of transmission components such as the lead screw and motor that drive the cleaning frame. Long-term use can easily lead to wear or damage to the mechanism.

[0005] The cleaning plate and spike support strip are easily damaged, shortening the equipment's lifespan: Under the immense scraping force, the notch edges of the cleaning plate, as an abrasive component, suffer severe abrasive wear, quickly becoming blunt or even chipped, leading to a rapid decline in cleaning effectiveness and requiring frequent replacement. Furthermore, this high-intensity, rigid scraping force also acts on the spike support strip being cleaned. The spike support strip is a key component ensuring the flatness and support accuracy of the worktable. It is typically made of hardened steel, but its small cross-section limits its resistance to lateral bending. Continuous, high-intensity lateral scraping force easily causes plastic bending deformation at the top of the spike support strip or fatigue damage at the root. Once the spike support strip deforms, it directly disrupts the flatness of the entire worktable, resulting in uneven plate placement. The negative impact on cutting accuracy is far greater than that of the slag itself.

[0006] Therefore, the core technical problem to be solved by this invention is: how to provide a highly efficient and automated cleaning solution with low cleaning resistance, effective stripping of molten slag, and minimal damage to the spiked support strip. Summary of the Invention

[0007] This invention addresses the aforementioned shortcomings of existing technologies by providing a laser cutting machine tool that is easy to clean. Through an active peeling cleaning mechanism of "claw engagement - upward swing," it fundamentally solves the problems of high resistance and high damage associated with translational scraping methods. Combined with a concealed storage design, multi-axis precision drive, and a closed-loop collection system, it constitutes a highly efficient, non-destructive, intelligent, and clean integrated cleaning solution. This not only significantly improves cleaning efficiency and quality but, more importantly, effectively protects the valuable spike support strips and the machine tool body, extending equipment lifespan and optimizing maintenance costs. To achieve the above objectives, the present invention provides the following technical solution: A laser cutting machine tool that is easy to clean includes a worktable and a light source system. The worktable is provided with spiked support bars for supporting workpieces. The outer side of the worktable is provided with opposing and movable columns. A crossbeam is connected between the two columns. A slag removal mechanism is provided on the crossbeam. The slag removal mechanism includes at least one cleaning component. The cleaning component is configured to be sleeved on the outer side of the spiked support bars in a vertical direction and to peel off the molten slag attached to the side of the spiked support bars by applying a bottom-up prying action. A collection device for receiving the peeled molten slag is provided below the spiked support bars.

[0008] Preferably, the workbench includes an inner support frame and an outer support frame sleeved on the outside of the inner support frame. A crossbeam is located between the inner support frame and the outer support frame. A storage space is provided between the outer support frame and the inner support frame. The crossbeam and the slag removal mechanism can be moved into the storage space for storage. A baffle is provided at the end of the outer support frame to close the storage space. Preferably, a second guide rod is provided on the outer side of the inner support frame. The two ends of the second guide rod are connected to the inner support frame through support blocks. A sliding seat is connected to the second guide rod. The column is connected to the sliding seat. The height of the column is adjustable.

[0009] Preferably, a support rod is connected between the two support blocks, a second rack is provided on the side wall of the support rod, a second motor and a second guide sleeve that cooperates with the second guide rod are provided on the side wall of the slide, and a second gear that meshes with the second rack is provided on the output shaft of the second motor. Preferably, the outer side of the support block is provided with support wheels that are connected to the inner support frame, a protective belt is sleeved between the two support wheels, the slide is located inside the protective belt, the slide is fixed to the protective belt, and the crossbeam passes through the protective belt.

[0010] Preferably, a guide rail and a lead screw are connected to the side wall of the column, a fourth motor is connected to the bottom of the lead screw, and a slider that cooperates with the guide rail and a nut sleeve that cooperates with the lead screw are provided on the side wall of the slide.

[0011] Preferably, the cleaning component includes a hook claw, a base connected above the hook claw, a hanging plate that cooperates with a crossbeam connected to the upper end of the base, a first rack connected to the side wall of the crossbeam, a first guide rod connected between the two columns, a first motor and a first guide sleeve that cooperates with the first guide rod at the upper end of the hanging plate, and a first gear that meshes with the first rack on the output shaft of the first motor.

[0012] Preferably, the lower end of the base is provided with an ear plate, the middle part of the hook claw is provided with a knife groove that cooperates with the spike support strip, one end of the hook claw is provided with a hook seat, a rotating shaft that cooperates with the ear plate is connected to the hook seat, a push shaft is connected to the rotating shaft, a turntable is connected to the top of the base, and a hydraulic cylinder is connected between the turntable and the push shaft.

[0013] Preferably, the hanging platform is connected to the turntable via a rotating shaft, a third motor connected to the rotating shaft is fixed at the lower end of the turntable, and a pull wheel that presses against the upper edge of the hanging platform is connected to the side wall of the turntable.

[0014] Preferably, a protective cover connected to the base is provided above the hook claw, and a camera connected to the base is provided at the upper opening of the protective cover.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Innovative Cleaning Mechanism: Achieving efficient and low-damage slag removal. The swinging hooks in the slag removal mechanism apply a combined bottom-up prying and shearing force to the slag. This force more effectively breaks the bond between the slag and the metal matrix, especially effective for firmly attached slag, overcoming the drawback of slag being "pushed" rather than "peeled" during lateral scraping. Because the direction of the force is more aligned with the slag's tendency to fall off, the driving torque required for cleaning is much less than the frictional force needed to move the cleaning plate as a whole, reducing energy consumption and lessening the load on the drive system. The direction of the upward swinging force coincides with the direction of the highest bending strength of the support bar, fundamentally avoiding the huge lateral bending moment generated by lateral scraping, greatly reducing the risk of bending deformation or damage to the spiked support bar, and protecting the core precision of the worktable.

[0016] 2. Modular Integration and Space Optimization: Achieving "Invisible" Storage and Rapid Recall. A dedicated storage space is created through the nested structure of inner and outer support frames. During non-cleaning periods, the entire beam, column, and cleaning mechanism can move along the guide device and be completely stored within this space, sealed by a baffle. This allows the cleaning system to be completely concealed during cutting operations, without encroaching on the laser cutting head's movement space or working area. Through control system commands, the cleaning mechanism can quickly move from its storage position and precisely position itself to the cleaning starting point, achieving rapid and seamless switching between cutting and cleaning modes, thus improving the overall utilization efficiency of the equipment.

[0017] 3. Multi-degree-of-freedom precision drive: Achieving adaptive and full-coverage cleaning. The cleaning head can move precisely in the X, Y, and Z directions, giving it high-precision multi-degree-of-freedom motion capabilities. This ensures that the claw's grooves accurately engage with each row of spiked support bars, achieving fully automated, no-dead-angle, and complete-coverage cleaning of the entire worktable without manual intervention. Furthermore, the slag removal mechanism can be rotated to adjust the cleaning direction, enabling reciprocating cyclic cleaning and improving efficiency.

[0018] 4. Synchronous Protection and Collection System: Ensuring Cleanliness and Equipment Safety. The protective belt rotates synchronously with the movement of the cleaning mechanism, effectively preventing scraped molten slag and debris from splashing onto the precision guide rails, lead screws, and other moving parts of the machine tool, avoiding secondary contamination and wear. The slag collection box, located directly below the spiked support bar, collects the falling molten slag in sync with the cleaning action. This fixed-point, sealed collection method changes the previous state of molten slag randomly scattered at the bottom of the equipment, maintaining the cleanliness of the equipment interior and facilitating centralized waste disposal.

[0019] 5. Enhanced Intelligence and Maintainability. Optional cameras provide visual monitoring of the support bars during or after the cleaning process, offering data support for evaluating cleaning effectiveness and predictive maintenance. Furthermore, the modular design makes the cleaning mechanism (such as the hook assembly) easy to disassemble, replace, or maintain, reducing long-term maintenance costs. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] like Figure 1 As shown, this invention provides an easy-to-clean laser cutting machine tool that integrates a highly efficient, non-destructive, and intelligent automated slag cleaning system. For example... Figure 2 As shown, this system is not a standalone add-on device, but rather, through ingenious structural design, it is deeply integrated with the machine tool body, achieving the integrated goal of "invisible during cutting and highly efficient during cleaning." The following will analyze its structure, connections, and collaborative working mechanisms layer by layer, from the overall framework to specific components.

[0023] First layer: Overall framework and space management: the cornerstone for realizing functional integration and mode switching. The entire plan revolves around efficient space utilization and seamless functional switching, and its physical carrier is a unique double-layer frame system.

[0024] Main frame (inner support frame 2 and outer support frame 1): Inner support frame 2: This is the core load-bearing structure of the machine tool. Numerous spiked support bars 201 are arrayed on its top, collectively forming the worktable surface supporting the plate. Molten slag adheres to the sides of these spiked support bars 201.

[0025] Outer support frame 1: Like an "outer cover," it fits around the inner support frame 2. The two form a closed, annular storage space 106. The ends of the outer support frame 1 are equipped with openable and closable baffles 101, serving as "doors" to this storage space. Figure 4 As shown, the inner wall of the outer support frame 1 is provided with a sliding groove 105, the two ends of the baffle 101 are engaged with the sliding groove 105, and the upper end of the baffle 101 is provided with a handle 102. The baffle 101 can be easily slid through the handle 102 to realize the opening and closing action.

[0026] This nested structure creates a physical "stealth" condition. Its core purpose is to completely house the entire cleaning execution mechanism (beam 4, column 5, and slag removal mechanism 3) within this space when no cleaning operation is being performed, and to enclose it with baffle 101. In this way, during laser cutting, the cleaning system occupies zero space and interferes with the movement and working area of ​​the cutting head, completely solving the problem of existing integrated cleaning mechanisms occupying internal space, and realizing physical isolation and rapid switching between cutting and cleaning modes.

[0027] The second layer: motion drive and precise positioning system: cleaning the "muscles" and "neural network" of the mechanism.

[0028] To precisely deliver the cleaning tool to each of the spike support strips on the worktable that need cleaning, the system is equipped with a multi-degree-of-freedom precision drive system. This system consists of two main moving units: Longitudinal movement unit (Y-axis and Z-axis driven): like Figure 5 , Figure 6 , Figure 7 As shown, the core of this unit is the slide 6 and the column 5. The slide 6 is mounted on the second guide rod 203 on the side of the inner support frame 2 via the second guide sleeve 602, achieving guidance along the length direction (Y-axis) of the worktable. Its power comes from the second motor 603 on the slide 6, which drives the second gear 604 to mesh with the second rack 204, thereby providing smooth longitudinal movement. The second rack 204 is fixed to the side wall of an independent support rod 207. The two ends of the support rod 207 are connected between two support blocks 202. Its core function is to serve as a high-rigidity mounting base for the second rack 204, ensuring that the rack 204 itself will not bend or vibrate when the gear 604 drives the slide 6 to move and transmits a large force, thus ensuring the long-term accuracy and stability of the Y-axis transmission.

[0029] like Figure 8As shown, the slide block 6 is connected to the guide rail 501 on the side of the column 5 via the slider 601. The column 5 has a lead screw 502 on its side wall, and the slide block 6 has a nut sleeve that mates with the lead screw 502 on its side wall. The bottom of the lead screw 502 has a fourth motor 503, which can drive the column 5 and the crossbeam 4 it supports to perform vertical lifting and lowering motion (Z-axis).

[0030] Connection and coordination: The slide 6 supports and drives the column 5 to move along the Y-axis; the lead screw of the column 5 is responsible for its own Z-axis lifting and lowering. The combination of the two determines the initial position and height of the cleaning mechanism in the YZ plane. The support rod 207 provides a stable and reliable support foundation for the entire Y-axis transmission system.

[0031] Lateral movement and rotation unit: The crossbeam 4 is mounted between two columns 5, forming the transverse movement track (X-axis) of the cleaning mechanism. A first rack 401 is installed on the side wall of the crossbeam 4, and first guide rods 402 connected to the columns 5 are provided on both sides of the crossbeam 4.

[0032] like Figure 9 , Figure 10 As shown, the slag removal mechanism 3 is "suspended" from the crossbeam 4 via a top mounting plate 304. The mounting plate 304 integrates a first motor 302 and a first gear 303. Figure 12 As shown, the first motor 302 drives the first gear 303 to mesh with the first rack 401 on the crossbeam 4, thereby driving the entire slag cleaning mechanism 3 to move precisely laterally (X-axis) along the crossbeam 4. The first guide sleeve 301 at the upper end of the hanging plate 304 cooperates with the first guide rod 402 to prevent the hanging plate 304 from twisting during movement.

[0033] Below the lifting platform 304, a turntable 306 is connected to a bearing via a pin. A third motor 314 at the bottom of the turntable 306 drives it to rotate 360°. To ensure smooth and stable rotation of the turntable 306, multiple pull rollers 305 are connected to its sidewalls. These pull rollers 305 press firmly against the upper edge of the lifting platform 304, effectively bearing the overturning moment and ensuring the rigidity and precision of the rotational motion. The core actuator of the slag removal mechanism, the cleaning head, is installed below this turntable 306.

[0034] The combination of linear and rotary motion along the X, Y, and Z axes gives the cleaning head the ability to position itself arbitrarily and adjust its angle in three-dimensional space. This allows the claw 309 to move precisely above any of the spiked support bars 201 and adjust to the optimal cleaning posture, achieving thorough, adaptive, and full-coverage cleaning of the entire workbench surface without any blind spots.

[0035] Core implementing mechanism: the "hand" that realizes the "proactive leveraging" of the cleanup mechanism. The end of the slag removal mechanism 3, namely the cleaning head, is the component that directly performs the cleaning action. Its design directly reflects the core idea of ​​low resistance and low damage in this solution.

[0036] Structural components: The base 307 serves as a mounting platform, fixed below the turntable 306, and a protective cover 308 and an optional camera 315 are fixed on it. The camera can be used for process monitoring or effect inspection. A lug 311 is provided at the lower end of the base 307.

[0037] like Figure 11 As shown, the hook 309 is the core tool, with a groove 316 in its center that matches the width of the spike support bar 201. The two sides of the groove 316 are made into inclined surfaces. This inclined surface guides the molten slag being stripped off to slide smoothly, preventing it from getting stuck in the groove and ensuring a smooth and efficient cleaning operation. One end of the hook 309 has a hook base 317, which is hinged to the ear plate 311 at the lower end of the base 307 via a pivot 310, allowing it to swing up and down. A push shaft 318 is connected to the pivot 310, and the push shaft 318, pivot 310, and hook base 317 are integrated into a single structure.

[0038] The hydraulic cylinder 313 is the power source for driving the swing. One end of it is hinged to the hinge point on the upper part of the turntable 306 or the base 307, and the other end is connected to the push shaft 318 of the hook 309.

[0039] A positioning plate 312 is located at the bottom of the base 307. The positioning plate 312 provides a precise mechanical limit and reset reference for the claw 309. The positioning plate 312 contacts and engages with the upper end of the spike support bar 201, ensuring that the claw 309 is at a consistent and correct height after each "slip-in" action, which greatly improves the repeatability and positioning accuracy of the cleaning action.

[0040] Working mechanism and effects: After the cleaning head is positioned by the drive system, it first descends, so that the groove 316 of the hook 309 fits on the outside of the spike support bar 201. The positioning plate 312 is in place after contacting the upper end of the spike support bar 201.

[0041] Subsequently, the hydraulic cylinder 313 extends, pushing the claw 309 upwards via the push shaft 318. This upward swing causes the upper edge of the cutter groove 316 to exert an upward prying and shearing force on the molten slag attached to the side of the spiked support bar. The "upward prying" force more easily breaks the bond between the molten slag and the substrate, and its direction of action is consistent with the molten slag's tendency to fall off, thus requiring less driving force and consuming less energy. Most importantly, this upward force is applied along the width direction of the spiked support bar 201 (i.e., its strongest direction), completely avoiding harmful lateral bending moments that could cause the support bar to bend and deform, fundamentally protecting the accuracy of the worktable.

[0042] Synchronous Protection and Collection System: A "Guarantee System" for Cleanliness and Equipment Longevity To protect the precision transmission components and maintain the cleanliness of the equipment's interior, the design incorporates a synchronously operating protection and collection device.

[0043] Protective belt 206: Support wheels 205 are provided on the outer side of the support block 202, and a ring-shaped flexible protective belt 206 is fitted on the two support wheels 205. The slide 6 is fixedly connected to the inner side of the protective belt 206. When the slide 6 moves in the Y-axis direction, it will drag the protective belt 206 to rotate synchronously.

[0044] The protective strip 206 acts like a "mobile protective curtain," constantly covering the precision linear components such as the second guide rod 203, the second rack 204, and the support rod 207. It effectively blocks debris that may fly after being peeled off by the claw 309, as well as debris generated during the cutting process, preventing it from adhering to and accumulating on the guide rail and rack, causing wear, corrosion, or jamming, thus providing synchronous dynamic protection.

[0045] like Figure 3 As shown, the collection device uses a slag receiving box 103: a pull-out slag receiving box 103 is installed directly below the array of spiked support bars 201 via a bracket 104.

[0046] Multiple slag collection boxes 103 are arranged side by side to accurately catch molten slag falling from above. In conjunction with the slag cleaning action (the molten slag is pried up and then falls off naturally under gravity), the molten slag is collected, preventing it from scattering around the bottom of the equipment, greatly simplifying subsequent cleaning work and keeping the internal environment of the equipment clean.

[0047] Usage steps (methods) Based on the above structure, the automatic cleaning function of this laser cutting machine tool operates according to the following steps: Preparation and Mode Switching: After the laser cutting operation is completed, the machine tool control system issues a cleaning command.

[0048] The baffle 101 at the end of the outer support frame 1 opens automatically or manually (operated via handle 102).

[0049] After the column 5 is raised, the second motor 603 drives the second gear 604 to mesh with the second rack 204, which in turn drives the slide 6 to move along the second guide rod 203, moving the cleaning system to the starting position above the workbench.

[0050] Positioning and Alignment: The control system coordinates the control of the X-axis (first motor 302), Y-axis (second motor 603), and Z-axis (fourth motor 503) according to the preset program.

[0051] First, the drive cleaning head moves to above the starting end of the first column of spike support bars 201 that need to be cleaned.

[0052] Adjust the height (Z-axis) and horizontal position (X, Y-axis) of the cleaning head so that the groove 316 of the claw 309 is accurately aligned with the spike support bar. The camera 315 can assist in visual positioning calibration.

[0053] Perform cleanup operations: like Figure 13 As shown, the cleaning head descends under Z-axis drive, causing the target spike support bar 21 to embed into the cutter groove 316 of the hook 309. The positioning plate 312 ensures that the hook's initial position remains consistent each time it resets.

[0054] like Figure 14 As shown, the prying action involves the hydraulic cylinder 313 actuating to drive the hook 309 to swing upwards, using the upper edge of the cutter groove 316 to pry the molten slag off from the side of the support bar. The detached molten slag, under the influence of gravity, is guided by the inclined outer wall of the cutter groove 316 and falls into the slag receiving box 103 below.

[0055] Reset and Stepping: After a single prying action is completed, the hydraulic cylinder 313 resets the claw 309 to a horizontal position. Then, the cleaning head moves a distance along the X-axis (this distance is no greater than the length of the claw 309) and repeats the "prying" action until the spiked support bar is completely cleaned.

[0056] In addition, this application includes three hooks 309, which can simultaneously clean three adjacent spike support bars. Of course, the number of hooks 309 can be increased or decreased as needed, such as from 2 to 5.

[0057] Coverage and Looping: After cleaning one support bar, the cleaning head rises, causing the claw 309 to separate from the spike support bar; then it rotates 180° while the crossbeam moves along the Y-axis to position itself on the next adjacent spike support bar to be cleaned, and repeats the above insertion, prying and stepping steps.

[0058] Completion and organization: After all the spiked support bars have been cleared, the columns, beams, and cleaning mechanism are moved above the storage space 106 and lowered for storage. The baffle 101 is then closed to completely enclose and conceal the cleaning system.

[0059] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this invention also intends to include these modifications and variations.
