Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment, and in particular to a moving beam laser cutting machine. Background Technology

[0002] To facilitate the loading and unloading of workpieces, the worktable of a moving beam laser cutting machine is usually designed as a movable structure, and the worktable moves in and out of the workspace via a moving guide rail.

[0003] However, laser cutting generates a large amount of dust, and gaps inevitably exist between the moving guide rails and the worktable, allowing this dust to easily enter the guide rails. Once inside, the dust accelerates wear, affects the worktable's movement accuracy and stability, shortens the guide rails' lifespan, and increases equipment maintenance costs and failure rates. Utility Model Content

[0004] The technical problem this invention aims to solve is that dust easily enters the interior of the moving guide rail of the worktable, accelerating the wear of the guide rail.

[0005] The solution to the technical problem of this utility model is: a moving beam laser cutting machine, comprising a shell, a first bed, a first worktable, a first drive device, a cutting device, a dustproof component, and two first guide rails. The shell encloses a working space, the first bed is disposed in the working space, the two first guide rails are arranged parallel to each other on the first bed, the first worktable is slidably connected to the first guide rails, the first drive device drives the first worktable to move along the first guide rails to enter and exit the working space, and the cutting device is disposed on the first bed and located above the first worktable. The cutting device can move along the length of the first bed to perform laser cutting on the workpiece on the first worktable. The dustproof component is disposed on the first bed and located between the two first guide rails. The dustproof component includes an exhaust fan, an exhaust pipe, and two side walls. The two side walls extend along the length of the first guide rails and enclose a cutting area. The top edge of the side walls is higher than the top surface of the first guide rails. The exhaust pipe is disposed between the two side walls along the length of the cutting area. The exhaust pipe has multiple dust suction holes that communicate with the cutting area. One end of the exhaust pipe is connected to the exhaust fan.

[0006] As a further improvement to the above technical solution, the cutting device includes a beam, a second guide rail, a laser cutting head, and a second driving device. The second guide rail is disposed on the first bed and is parallel to the first guide rail. The beam is slidably connected to the second guide rail. The second driving device drives the beam to move along the second guide rail. The laser cutting head is disposed on the beam.

[0007] As a further improvement to the above technical solution, the cutting device further includes a third guide rail and a third driving device. The third guide rail is disposed on the beam and perpendicular to the second guide rail. The laser cutting head is slidably connected to the third guide rail, and the third driving device drives the laser cutting head to move along the third guide rail.

[0008] As a further improvement to the above technical solution, the first workbench includes a frame, two baffles and multiple toothed plates. The multiple toothed plates are arranged at equal intervals along the length of the frame to form a sawtooth support surface. The baffles are arranged on both sides of the bottom of the frame along the length of the frame and are inclined downwards towards the inside of the frame.

[0009] As a further improvement to the above technical solution, the dustproof component also includes a filter screen and a dust-blocking strip. The filter screen covers the dust suction hole, and the dust-blocking strip is disposed on the exhaust pipe and located above the dust suction hole. The dust-blocking strip is inclined downward in a direction away from the exhaust pipe.

[0010] As a further improvement to the above technical solution, the dustproof component also includes a protective component, which includes a fireproof brick and two guide plates. The two guide plates are arranged in an inverted V shape on the top surface of the exhaust pipe, and the fireproof brick is arranged on the outer side of the guide plates near the cutting area.

[0011] As a further improvement to the above technical solution, the dustproof assembly also includes multiple flap assemblies. Each flap assembly includes a flap body, a guide block, a cylinder, and a roller. One end of the flap body is hinged to the exhaust pipe. The guide block is fixedly connected to the flap body and is provided with a flap guide rail. The roller is disposed on the drive part of the cylinder and can rotate relative to the drive part of the cylinder. The roller is slidably connected to the flap guide rail to push the flap body to open or close the dust suction hole one by one.

[0012] As a further improvement to the above technical solution, an anti-collision component is also included. The anti-collision component includes a buffer block and a limit switch, both disposed at the ends of the first bed. The limit switch is electrically connected to the first drive device. When the first worktable moves to the limit position, the buffer block abuts against one end of the first worktable, and one end of the first worktable triggers the limit switch to de-energize the first drive device.

[0013] As a further improvement to the above technical solution, a hopper car is also included. The hopper car is located below the dustproof component. The dustproof component also includes multiple guide plates. A material collection port is formed between the exhaust pipe and the side wall. The guide plates extend downward at an angle along the edge of the material collection port to the top of the hopper car.

[0014] As a further improvement to the above technical solution, an adjustment assembly is also included at the bottom of the first bed for support and leveling. The adjustment assembly includes a foot cup base, a threaded post, an adjusting nut, a support block, a washer, and a fixing bolt. The threaded post is disposed on the foot cup base, and the adjusting nut is threadedly connected to the external thread of the threaded post. The top surface of the adjusting nut is configured as a rounded boss, and the bottom surface of the support block is recessed with a groove that matches the boss. The threaded post is provided with an internal threaded hole, and the fixing bolt is threadedly connected to the internal threaded hole so that the washer and the support block passing through the fixing bolt press against the first bed.

[0015] The beneficial effects of this utility model are: the outer shell encloses the working space, which to a certain extent prevents dust and other particles from spreading excessively outward; the first bed provides stable support; the first worktable moves in and out of the working space along the first guide rail under the drive of the first drive device, which facilitates the loading and unloading of workpieces and cutting processing in a suitable position; the cutting device can move along the length of the first bed to perform laser cutting processing on the workpiece placed on the first worktable; the two side walls enclose the cutting area, blocking the dust from spreading in the direction of the guide rail, and the exhaust fan generates suction to create negative pressure in the exhaust pipe, thereby extracting the dust in the cutting area. This invention, by incorporating a dustproof component, utilizes two side walls to enclose the cutting area, effectively preventing dust from entering the first guide rail from the cutting area. This reduces dust contamination of the first guide rail and helps maintain its good working condition. An exhaust pipe is positioned between the two side walls along the length of the cutting area, and the exhaust pipe has multiple dust-collecting holes connecting to the cutting area. Combined with the exhaust fan, this can extract some dust from the cutting area, further reducing the possibility of dust spreading to the guide rail. This ensures the smoothness and precision of the first worktable's movement along the first guide rail, thus improving the overall quality and efficiency of the laser cutting process.

Detailed Implementation

[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments have been briefly explained above. Obviously, the described drawings are only a part of the embodiments of this utility model, not all of them. Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] To facilitate the loading and unloading of workpieces, the worktable of a moving beam laser cutting machine is usually designed as a movable structure, and the worktable moves in and out of the workspace via a moving guide rail.

[0021] However, laser cutting generates a large amount of dust, and gaps inevitably exist between the moving guide rails and the worktable, allowing this dust to easily enter the guide rails. Once inside, the dust accelerates wear, affects the worktable's movement accuracy and stability, shortens the guide rails' lifespan, and increases equipment maintenance costs and failure rates.

[0022] Therefore, this utility model proposes a moving beam laser cutting machine, referring to... Figures 1-5 It includes a housing 100, a first bed 200, a first worktable 300, a first drive unit, a cutting device 500, a dustproof component 600, and two first guide rails 210. The housing 100 encloses a working space, the first bed 200 is disposed in the working space, the two first guide rails 210 are arranged parallel to each other on the first bed 200, the first worktable 300 is slidably connected to the first guide rails 210, the first drive unit drives the first worktable 300 to move along the first guide rails 210 to enter and exit the working space, the cutting device 500 is disposed on the first bed 200 and located above the first worktable 300, and the cutting device 500 can move along the first bed 200. The bed 200 moves along its length to perform laser cutting on the workpiece on the first worktable 300. The dustproof component 600 is disposed on the first bed 200 and located between the two first guide rails 210. The dustproof component 600 includes an exhaust fan, an exhaust pipe 620, and two side walls 630. The two side walls 630 extend along the length of the first guide rails 210 and enclose to form a cutting area. The top edge of the side wall 630 is higher than the top surface of the first guide rails 210. The exhaust pipe 620 is disposed between the two side walls 630 along the length of the cutting area. The exhaust pipe 620 has multiple dust suction holes communicating with the cutting area. One end of the exhaust pipe 620 is connected to the exhaust fan.

[0023] The outer shell 100 encloses the working space, which to some extent prevents dust and other particles from spreading excessively outward; the first bed 200 provides stable support; the first worktable 300 moves along the first guide rail 210 into and out of the working space under the drive of the first drive device, which facilitates the loading and unloading of workpieces and the cutting and processing at a suitable position; the cutting device 500 can move along the length of the first bed 200 to perform laser cutting processing on the workpiece placed on the first worktable 300; the two side walls 630 enclose the cutting area, blocking the dust from spreading in the direction of the guide rail, and the exhaust fan generates suction to create negative pressure in the exhaust pipe 620, thereby extracting the dust in the cutting area. This invention, by setting up a dustproof component 600, utilizes two side walls 630 to enclose the cutting area, effectively preventing dust from entering the first guide rail 210 from the cutting area, reducing dust contamination of the first guide rail 210, and helping to maintain the guide rail in good working condition; the exhaust pipe 620 is set between the two side walls 630 along the length of the cutting area, and the exhaust pipe 620 is provided with multiple dust suction holes communicating with the cutting area. In conjunction with the exhaust fan, it can extract some dust from the cutting area, further reducing the possibility of dust spreading to the guide rail, ensuring the smoothness and accuracy of the first worktable 300 moving along the first guide rail 210, which is conducive to improving the quality and efficiency of the entire laser cutting process.

[0024] During laser cutting, the cutting device 500 emits a laser beam to cut the workpiece on the first worktable 300, generating dust in the process. The dustproof component 600 functions, with the cutting area enclosed by the two side walls 630 preventing most of the dust from drifting to the first guide rails 210 on both sides. Meanwhile, the exhaust fan generates suction, creating negative pressure within the exhaust pipe 620, drawing some of the dust from the cutting area into the exhaust pipe 620 and discharging it through the dust extraction holes. After cutting, the first worktable 300, driven by the first driving device, moves the workpiece along the first guide rail 210 out of the workspace for easy unloading. The dustproof component 600 ensures that the first worktable 300, driven by the first driving device, can move smoothly and accurately along the relatively clean first guide rail 210, ensuring the orderly execution of the entire laser cutting process. Specifically, the first driving device is configured as a chain and sprocket transmission mechanism. Alternatively, the first driving device can employ other linear module structures such as a ball screw linear transmission mechanism, a gear and rack transmission mechanism, or a linear motor-type linear module.

[0025] In one embodiment, the cutting device 500 includes a beam 510, a second guide rail 520, a laser cutting head 530, and a second driving device 540. The second guide rail 520 is disposed on the first bed 200 and parallel to the first guide rail 210. The beam 510 is slidably connected to the second guide rail 520. The second driving device 540 drives the beam 510 to move along the second guide rail 520. The laser cutting head 530 is disposed on the beam 510. By disposing the second guide rail 520 on the first bed 200 and parallel to the first guide rail 210, and by slidably connecting the beam 510 to the second guide rail 520, the laser cutting head 530 can move along the second guide rail 520 with the beam 510. Combined with the movement of the first worktable 300 on the first guide rail 210, the coverage area of ​​the cutting head on the workpiece plane is expanded, thereby enabling comprehensive cutting processing of workpieces of different positions and sizes, improving the applicability of the equipment. Specifically, the second drive device 540 is configured as a gear and rack transmission mechanism. The second drive device 540 may also adopt other linear module structures such as a ball screw linear transmission mechanism or a linear motor type linear module.

[0026] In one embodiment, the cutting device 500 further includes a third guide rail 550 and a third driving device 560. The third guide rail 550 is disposed on the beam 510 and perpendicular to the second guide rail 520. The laser cutting head 530 is slidably connected to the third guide rail 550, and the third driving device 560 drives the laser cutting head 530 to move along the third guide rail 550. Through the vertical arrangement of the third guide rail 550 and the second guide rail 520, the laser cutting head 530 can be precisely positioned at any location in the XY plane, expanding the equipment's processing capabilities. The third guide rail 550 is integrated into the beam 510, achieving two-dimensional cutting without additionally increasing the equipment's footprint, making it particularly suitable for the space-constrained requirements of small and medium-sized processing workshops. Specifically, the third driving device 560 is configured as a gear and rack transmission mechanism, and the second driving device 540 can also adopt other linear module structures such as a ball screw linear transmission mechanism or a linear motor-type linear module.

[0027] Preferably, the third guide rail 550 is disposed on the top of the beam 510, and the cutting assembly further includes a fourth guide rail 570, which is disposed on one side of the beam 510 and parallel to the third guide rail 550. The cutting assembly is slidably connected to the third guide rail 550 and the fourth guide rail 570 via a slider. The cutting assembly is simultaneously slidably connected to both the third guide rail 550 at the top of the beam 510 and the fourth guide rail 570 on one side of the beam 510 via a slider, allowing the cutting assembly to receive effective support and guidance from different directions during movement. The dual guide rails can better distribute the external forces on the cutting assembly, avoiding instability such as swaying and deviation caused by uneven force distribution, improving the stability of the cutting assembly's movement, ensuring the accuracy of the cutting trajectory, and thus improving the cutting quality.

[0028] Preferably, the laser cutting head 530 includes a cutting bracket 531, a fifth guide rail 532, a cutting head body 533, a fourth driving device 534, and a cable chain 535. The cutting bracket 531 is slidably connected to the third guide rail 550. The fifth guide rail 532 is vertically disposed on the cutting bracket 531. The cutting head body 533 is slidably connected to the fifth guide rail 532 via a slider. The fourth driving device 534 drives the cutting head body 533 to move up and down along the fifth guide rail 532. The cutting head body 533 and the cutting bracket 531 are connected by the cable chain 535. The center plane of the cable chain 535 forms an angle α with the length direction of the third guide rail 550, where α is 45°. By employing a 45° angled layout, when the cutting head is subjected to horizontal vibration, the force generated by the vibration is decomposed along the oblique direction of the cable chain 535. A portion of this force is converted into axial tensile force on the cable chain 535, rather than directly acting on the cutting head to cause significant swaying. This effectively suppresses instability phenomena such as wobbling and offset of the cutting head caused by horizontal vibration, allowing the cutting head to maintain a more stable state during vertical movement and cutting, thus improving cutting accuracy and processing quality. Specifically, the third drive device 560 is configured as a ball screw linear transmission mechanism, while the second drive device 540 can also adopt other linear module structures such as a gear and rack transmission mechanism or a linear motor type linear module.

[0029] Waste generated during cutting may be scattered randomly on the workbench, accumulating and affecting the placement of subsequent workpieces and cutting operations. Therefore, in one embodiment, the first workbench 300 includes a frame 310, two baffles 320, and multiple toothed blades 330. The multiple toothed blades 330 are arranged at equal intervals along the length of the frame 310 to form a serrated support surface. The baffles 320 are arranged on both sides of the bottom of the frame 310 along the length of the frame 310, and the baffles 320 are inclined downwards towards the inside of the frame 310. The arrangement of multiple toothed blades 330 at equal intervals along the length of the frame 310 to form a serrated support surface increases the friction with the bottom surface of the workpiece, making the workpiece more stable when placed on the workbench and reducing the possibility of workpiece displacement. The baffles 320 are arranged on both sides of the bottom of the frame 310 along the length of the frame 310 and are inclined downwards towards the inside of the frame 310. After waste is generated during cutting, the waste can slide down along the inclined baffles 320, making it easy to collect and clean.

[0030] Large particles generated during cutting may enter the exhaust duct 620 and clog it. Therefore, in one embodiment, the dustproof assembly 600 further includes a filter screen 640 and a slag-blocking strip 650. The filter screen 640 covers the dust suction hole, and the slag-blocking strip 650 is disposed on the exhaust duct 620 and located above the dust suction hole, with the strip inclined downwards away from the exhaust duct 620. The filter screen 640, covering the dust suction hole, can effectively intercept large particles generated during cutting, preventing blockage inside the exhaust duct 620 and maintaining good dust suction performance. The slag-blocking strip 650, disposed on the exhaust duct 620 and located above the dust suction hole, prevents waste from splashing under the suction force, altering the trajectory of the waste and causing it to slide down along the inclined direction of the strip, thus helping to keep the work area clean.

[0031] Sparks and debris from the cutting process can easily fall directly onto the top of the exhaust duct 620. These sparks may burn through the exhaust duct 620, causing air leakage in the ventilation system. Therefore, in one embodiment, the dustproof component 600 further includes a protective component 660. The protective component 660 includes a fireproof brick 661 and two guide plates 662. The two guide plates 662 are arranged in an inverted V-shape on the top surface of the exhaust duct 620, and the fireproof brick 661 is disposed on the outer surface of the guide plates 662 near the cutting area. The fireproof brick 661 effectively blocks the flame, preventing the fire from spreading along the exhaust duct 620. The two guide plates 662, arranged in an inverted V-shape on the top surface of the exhaust duct 620, guide sparks generated during cutting to slide to both sides, preventing them from falling directly onto the exhaust duct 620; they also guide debris and other impurities generated during cutting to slide to both sides, preventing them from accumulating on the top of the exhaust duct 620 and reducing problems caused by the accumulation of foreign objects.

[0032] When the workbench is long, it may be necessary to increase the power of the exhaust fan to ensure the suction power of all dust collection holes, which will accelerate the wear of the exhaust fan. Therefore, in one embodiment, the dustproof component 600 also includes multiple flap components 670. Each flap component 670 includes a flap body 671, a guide block 672, a cylinder 673, and a roller 674. One end of the flap body 671 is hinged to the exhaust pipe 620. The guide block 672 is fixed to the flap body 671 and is provided with a flap guide rail. The roller 674 is disposed on the drive part of the cylinder 673 and can rotate relative to the drive part of the cylinder 673. The roller 674 is slidably connected to the flap guide rail to push the flap body 671 to open or close the dust collection holes one by one. The cylinder 673 drives the roller 674 to slide on the flip plate guide rail, which in turn pushes the flip plate body 671 to open or close the dust suction holes accordingly. This allows control over the number and position of the dust suction holes, enabling flexible adjustment of the dust suction intensity and range. This ensures good dust prevention while avoiding unnecessary energy consumption and improving the energy efficiency of the equipment. The flip plate assembly 670 can also be used to adjust the opening and closing state of the dust suction holes as needed, keeping the airflow in the cutting area relatively stable. This reduces cutting deviations caused by unstable dust suction airflow, helps improve cutting accuracy, and ensures processing quality.

[0033] When the first worktable 300 moves to its limit position, it may collide with the end of the first bed 200 due to external force or inertia, damaging the equipment. Therefore, in one embodiment, an anti-collision component 700 is also included. The anti-collision component 700 includes a buffer block 710 and a limit switch 720, both disposed at the end of the first bed 200. The limit switch 720 is electrically connected to the first drive device. When the first worktable 300 moves to its limit position, the buffer block 710 abuts against one end of the first worktable 300, and one end of the first worktable 300 triggers the limit switch 720 to de-energize the first drive device. When the first worktable 300 moves to its limit position due to an unexpected situation, the buffer block 710 can first come into contact with one end of the worktable, reducing the direct hard impact between the worktable and the first bed 200, and avoiding deformation and damage to the parts caused by violent collision; at the same time, one end of the first worktable 300 triggers the limit switch 720, which will immediately send a signal to the first drive device to stop driving the worktable, prevent the worktable from continuing to move to the limit position, eliminate collision accidents caused by excessive movement, and ensure the safe operation of the equipment.

[0034] Waste generated during cutting may accumulate inside the dustproof component 600 or on the ground around the equipment, affecting the working environment. Therefore, in one embodiment, a hopper 800 is also included, which is located below the dustproof component 600. The dustproof component 600 also includes multiple guide plates 680, and a collection port is formed between the exhaust pipe 620 and the side wall 630. The guide plates 680 extend downwards along the edge of the collection port to above the hopper 800. Guided by the guide plates 680, debris that falls naturally from the cutting area smoothly enters the hopper 800. When the hopper 800 is full, it can be easily pushed away for dumping, simplifying the cleaning process. This prevents waste from scattering and accumulating around the equipment, keeping the entire laser cutting working area relatively clean and tidy, while also reducing potential damage to the equipment caused by debris accumulation and ensuring the normal operation of the equipment.

[0035] During adjustment, the support block 224 rotates relative to the first bed 200, generating significant friction that may scratch or wear the bottom surface of the first bed 200. Therefore, in one embodiment, referring to... Figure 6It also includes an adjustment assembly 220 disposed at the bottom of the first bed 200 for support and leveling. The adjustment assembly 220 includes a foot cup base 221, a threaded post 222, an adjusting nut 223, a support block 224, a washer 225, and a fixing bolt 226. The threaded post 222 is disposed on the foot cup base 221. The adjusting nut 223 is threadedly connected to the external thread of the threaded post 222. The top surface of the adjusting nut 223 is configured as a rounded boss. The bottom surface of the support block 224 is recessed and formed with a groove that matches the boss. The threaded post 222 is provided with an internal threaded hole. The fixing bolt 226 is threadedly connected to the internal threaded hole so that the washer 225 and the support block 224, which are inserted in the fixing bolt 226, press against the first bed 200. By adjusting the threaded engagement between the adjusting nut 223 and the threaded post 222, the height of each support point of the first bed 200 can be precisely adjusted according to the actual ground conditions, so that the first bed 200 reaches a horizontal state. The arc-shaped boss on the top surface of the adjusting nut 223 matches the groove on the bottom surface of the support block 224 to form a spherical contact pair. During the adjustment process, when the adjusting nut 223 rotates, the support block 224 only makes up-down linear movement without rotating, avoiding relative sliding friction between the support block 224 and the bottom surface of the first bed 200, thereby reducing wear on the surface of the first bed 200 and extending the service life of the first bed 200. After the adjustment is in place, the shim 225 and the support block 224 are pressed onto the first bed 200 by the fixing bolt 226. Utilizing the self-locking characteristics of the thread and the anti-loosening effect of the shim 225, the adjustment component 220 can be effectively prevented from loosening due to vibration during operation, ensuring that the first bed 200 always remains in the adjusted horizontal position, thus improving the stability and reliability of the equipment.

[0036] Preferably, to improve work efficiency and enable the laser cutting machine to continuously process multiple sheets, in one embodiment, the laser cutting machine further includes a second bed 900 and a second worktable 910 mounted on the second bed 900. The first bed 200 and the second bed 900 are detachably connected. The first worktable 300 and the second worktable 910 have the same structure. The first worktable 300 and the second worktable 910 are interchanged in position via an interactive drive device. The first worktable 300, the second worktable 910, and the interactive drive device constitute a ramp-type exchange platform. In another embodiment, the first worktable 300, the second worktable 910, and the interactive drive device constitute a translational exchange platform. It should be noted that both the ramp-type exchange platform and the translational exchange platform are existing technologies, and the specific structure of the exchange drive device will not be described in detail here.

[0037] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
