[0025] Manual loading and unloading has always been the traditional method for loading laser cutting systems. This involves moving raw materials and placing them in designated areas of the laser cutting machine, ensuring the materials are correctly positioned, located, and angled for optimal cutting. After the machine completes the cut, the finished product must be manually removed, and waste materials separated from the cut material. Frequent manual handling is not only time-consuming and labor-intensive, but also generates significant waiting time during material transfers, severely reducing the overall efficiency of the cutting process and failing to meet the high-efficiency requirements of large-scale production.

[0026] Therefore, this utility model proposes a laser cutting machine, referring to... Figures 1-6 It includes a frame 100, a first guide rail 200, a second guide rail 210, a loading platform 300, a processing table 400, a unloading platform 500, a first transfer assembly 600, a cutting assembly 700, and a second transfer assembly 800. The first guide rail 200 is disposed on the frame 100. The loading platform 300, the processing table 400, and the unloading platform 500 are sequentially disposed on the frame 100 along the length of the first guide rail 200. The second guide rail 210 is disposed on the frame 100 and located on one side of the processing table 400. The second guide rail 210 is perpendicular to the first guide rail 200. The first material transfer component 600 is slidably connected to the first guide rail 200 and is used to transfer the material to be cut from the loading platform 300 to the processing platform 400. The cutting component 700 is slidably connected to the second guide rail 210 and is used to cut the material on the processing platform 400. The second material transfer component 800 is slidably connected to the first guide rail 200 and is used to transfer the cut material from the processing platform 400 to the unloading platform 500.

[0027] The frame 100 provides a stable mounting base; the first guide rail 200 provides sliding guidance for the first material transfer assembly 600 and the second material transfer assembly 800; the loading platform 300 holds the material to be cut; the first material transfer assembly 600 grabs the material to be cut from the loading platform 300, realizing the transfer of material from the preparation stage to the processing stage; the processing table 400 ensures that the material will not shift or affect the cutting quality when the cutting assembly 700 cuts the material on it; the cutting assembly 700 cuts the material by sliding and adjusting the cutting position on the second guide rail 210; the second material transfer assembly 800 grabs the cut material from the processing table 400 and unloads it; the unloading platform 500 receives the cut material for easy collection and sorting later. By setting up a loading platform 300, a processing platform 400, and a unloading platform 500, and equipping them with corresponding material transfer components, the loading and unloading of materials to be cut can be realized, reducing manual operation time and material transfer interval time, thereby improving overall processing efficiency; reducing manual intervention, reducing errors that may be caused by manual operation, and also reducing labor costs, making it suitable for large-scale industrial production.

[0028] During processing, the material to be cut is placed on the loading platform 300. The first material transfer component 600 slides along the first guide rail 200 to the corresponding position on the loading platform 300, grabs the material to be cut, and moves along the first guide rail 200 to the processing table 400, where it is placed. The cutting component 700 slides along the second guide rail 210, which is perpendicular to one side of the processing table 400, and after adjusting the cutting position, it cuts the material on the processing table 400. After the cutting is completed, the second material transfer component 800 slides along the first guide rail 200 to the position on the processing table 400, grabs the cut material, and moves it to the unloading platform 500, where it is placed for subsequent collection and sorting.

[0029] In one embodiment, the first transfer assembly 600 includes a first transfer frame 610, a first slider 620, a first driving device 630, a third guide rail 640, a third slider 650, a first cylinder 660, and a first suction cup assembly 670. The first slider 620 is slidably connected to the first guide rail 200. The first transfer frame 610 is disposed on the first slider 620. The third guide rail 640 is vertically disposed on the first transfer frame 610. The third slider 650 is slidably connected to the third guide rail 640. The first suction cup assembly 670 is disposed on the third slider 650. The first suction cup assembly 670 is fixedly connected to the driving part of the first cylinder 660. The first cylinder 660 drives the first suction cup assembly 670 to move up and down along the third guide rail 640. The first driving device 630 drives the first transfer frame 610 to move along the first guide rail 200. The sliding connection between the first slider 620 and the first guide rail 200, along with the driving action of the first driving device 630, enables the first material transfer rack 610 to move precisely between different worktables. Simultaneously, the first cylinder 660 drives the first suction cup assembly 670 to move up and down along the third guide rail 640, precisely adjusting the height of the suction cup assembly to ensure that materials are in accurate positions during gripping and placement. This reduces positioning inaccuracies that may result from human operation, ensuring high-quality cutting and processing. It also lowers labor costs, reduces the workload of workers, and makes the production process more economical and efficient.

[0030] In one embodiment, the second transfer assembly 800 includes a second transfer frame 810, a second slider 820, a second driving device 830, a fourth guide rail 840, a fourth slider 850, a second cylinder 860, and a second suction cup assembly 870. The second slider 820 is slidably connected to the first guide rail 200. The second transfer frame 810 is disposed on the second slider 820. The fourth guide rail 840 is vertically disposed on the second transfer frame 810. The fourth slider 850 is slidably connected to the fourth guide rail 840. The second suction cup assembly 870 is disposed on the fourth slider 850. The second suction cup assembly 870 is fixedly connected to the driving part of the second cylinder 860. The second cylinder 860 drives the second suction cup assembly 870 to move up and down along the fourth guide rail 840. The second driving device 830 drives the second transfer frame 810 to move along the first guide rail 200. Through the coordinated operation of the second drive device 830, slider, and guide rail, the second material transfer assembly 800 can quickly transfer the cut material on the processing table 400 to the unloading table 500, significantly reducing the time spent on the unloading process compared to the traditional manual unloading method. The sliding connection between the second slider 820 and the first guide rail 200, as well as the driving action of the second drive device 830, enables the second material transfer rack 810 to be accurately positioned at the corresponding positions on the processing table 400 and the unloading table 500. The second cylinder 860 drives the second suction cup assembly 870 to move up and down along the fourth guide rail 840, which can precisely adjust the height of the suction cup assembly to ensure that the material is in the correct position when being gripped and placed, avoiding placement deviations that may occur during manual unloading and ensuring the accuracy of material transfer.

[0031] The laser head 718 may not be able to achieve cutting along complex trajectories, thus limiting cutting accuracy and processing capabilities. Therefore, in one embodiment, the cutting assembly 700 includes a third driving device 710, a fifth slider 711, a fifth guide rail 712, a fourth driving device 713, a sixth slider 714, a sixth guide rail 715, a fifth driving device 716, a seventh slider 717, and a laser head 718. The fifth slider 711 is slidably connected to the second guide rail 210. The third driving device 710 drives the fifth slider 711 to move along the second guide rail 210. The fifth guide rail 712 is disposed on the fifth slider 711 and is connected to... The first guide rail 200 is arranged in parallel. The sixth slider 714 is slidably connected to the fifth guide rail 712. The fourth driving device 713 drives the sixth slider 714 to move along the fifth guide rail 712. The sixth guide rail 715 is vertically arranged on the sixth slider 714. The seventh slider 717 is slidably connected to the sixth guide rail 715. The fifth driving device 716 drives the seventh slider 717 to move up and down along the sixth guide rail 715. The laser head 718 is arranged on the seventh slider 717. Through three mutually perpendicular guide rails and corresponding driving devices, the laser head 718 can achieve precise movement in the X, Y, and Z directions, enabling it to complete various complex trajectory cutting tasks, greatly improving cutting accuracy and flexibility. Precise cutting control also reduces material waste and equipment damage caused by improper operation.

[0032] Specifically, the first drive device 630, the second drive device 830, the third drive device 710, the fourth drive device 713 and the fifth drive device 716 adopt ball screw linear transmission mechanism, or other linear module structures such as linear motor type linear module.

[0033] The large amount of smoke and debris generated during cutting can fill the working area. Therefore, in one embodiment, the cutting assembly 700 further includes a dust collection box 720, which is fixed to the sixth slider 714. The suction end of the dust collection box 720 faces the laser head 718, and the inner cavity of the dust collection box 720 is connected to a negative pressure air source. By communicating with the negative pressure air source, the dust collection box 720 can promptly remove the smoke and debris generated during cutting, effectively reducing the spread of pollutants in the working area and creating a good working environment. Timely removal of cutting debris can prevent debris from entering the gaps of moving parts such as guide rails and sliders, reducing the probability of equipment failure caused by foreign objects entering, and ensuring the continuous and stable operation of the entire laser cutting equipment.

[0034] Traditional fixed loading platforms may struggle to achieve ideal positioning when handling materials of varying shapes and sizes. Therefore, in one embodiment, the loading platform 300 includes a loading rack 310, a rotating shaft 320, a swing arm 330, a sixth drive device 340, four swing rods 350, four sets of clamping assemblies 360, four seventh guide rails, and four eighth sliders. The loading rack 310 is mounted on the frame 100. The rotating shaft 320 is mounted on the loading rack 310 and is rotatable relative to it. The swing arms 330 are coaxially rotatable with the rotating shaft 320. One end of each of the four swing rods 350 is connected to the swing arm. The four corners of the 330 are hinged, and the other end of the swing arm 350 is hinged to the clamping assembly 360. The seventh guide rail is set on the loading rack 310, and the eighth slider is slidably connected to the seventh guide rail. The clamping assembly 360 is set on the eighth slider. The sixth driving device 340 is set on the loading rack 310. The sixth driving device 340 is used to drive the rotating shaft 320 to rotate, so as to drive the clamping assembly 360 to move radially along the center of the rotating shaft 320. Through the coordinated action of the rotating shaft 320, the swing arm 330 and the swing arm 350, the four clamping assemblies 360 can move radially along the center of the rotating shaft 320, and can flexibly adjust the clamping position and angle for materials of different shapes and sizes. This allows the loading table 300 to adapt to various materials to be cut. Whether the material is regular or irregular in shape, it can be easily positioned and fixed, enhancing the adaptability of the loading process to different materials.

[0035] During cutting, workpieces may become unstable or inaccurately positioned, affecting the quality and precision of subsequent laser cutting. Therefore, in one embodiment, the processing table 400 includes an eighth guide rail 410, a first adjusting rod 420, a second adjusting rod 430, a first bushing 440, a second bushing 450, a handwheel 460, and an adjusting shaft 470. The eighth guide rail 410 is mounted on the frame 100. The first adjusting rod 420 and the second adjusting rod 430 are slidably connected to the eighth guide rail 410. The first adjusting rod 420 and the second adjusting rod 430 enclose a processing space for placing the workpiece. The first bushing 440 is connected to the... The first adjusting rod 420 is fixedly connected, and the second bushing 450 is fixedly connected to the second adjusting rod 430. The adjusting shaft 470 is mounted on the frame 100 and can rotate relative to the frame 100. The handwheel 460 is coaxially rotatably mounted with the adjusting shaft 470. The adjusting shaft 470 has a first threaded section and a second threaded section, with the threads of the first threaded section and the second threaded section having opposite directions. The first bushing 440 is threadedly connected to the first threaded section, and the second bushing 450 is threadedly connected to the second threaded section. By rotating the handwheel 460, the first adjusting rod 420 and the second adjusting rod 430 can slide towards or away from each other along the eighth guide rail 410, thereby flexibly changing the size of the processing space formed by the two, easily adapting to workpieces of different sizes, providing precise support for the edges of the workpiece, ensuring that the workpiece is placed stably and accurately on the processing table 400, which is beneficial to improving the accuracy of subsequent laser cutting and reducing cutting quality problems caused by unstable workpiece placement or positioning deviation.

[0036] Under the heat and mechanical force generated by laser cutting, the workpiece may warp or deform. Therefore, in one embodiment, the processing table 400 further includes a connecting rod 480 and a support block 490. The connecting rod 480 is disposed on the frame 100 and located between the first adjusting rod 420 and the second adjusting rod 430. The connecting rod 480 has a slot 481, and the support block 490 can slide relative to the slot 481. The support block 490 is fixed to the slot 481 by bolts. By providing a slidable support block 490 between the first adjusting rod 420 and the second adjusting rod 430, additional support can be provided to the central area of ​​the workpiece, effectively reducing warping and deformation of the workpiece during the cutting process. The support block 490 can slide within the slot 481 of the connecting rod 480 and is fixed in any position by bolts. The position of the support block 490 can be flexibly adjusted according to the specific shape and size of the workpiece, expanding the applicability of the processing table 400 and improving the versatility of the equipment.

[0037] Waste generated during cutting can scatter everywhere, making the work area cluttered. Therefore, in one embodiment, the laser cutting machine further includes a material collection component, which includes a material collection hopper and a material collection box both mounted on the frame 100. The material collection hopper is located below the processing table 400, and its output end is connected to the material collection box. The material collection hopper can promptly catch waste and debris falling during cutting, preventing them from scattering on the ground or around the equipment, making the entire work area cleaner and tidier. Waste and scrap generated during cutting flow from the material collection hopper into the material collection box for centralized storage, facilitating subsequent unified processing of these waste materials and improving waste management efficiency.

[0038] The material collection bin needs to be disassembled and reinstalled when cleaning waste, a process that typically takes a considerable amount of time, increasing downtime for the laser cutting equipment and impacting production efficiency. Therefore, in one embodiment, the material collection assembly further includes a ninth guide rail, which is mounted on the frame 100, and the material collection bin is slidably connected to the ninth guide rail. This sliding connection between the ninth guide rail and the material collection bin allows it to be easily slid off the guide rail when full of waste, enabling quick replacement with an empty bin, reducing downtime caused by waste cleaning, and improving production efficiency.
