[0033] In the description of the utility model, unless otherwise expressly limited, the words such as setting, installation, connection should be understood broadly, and the skilled in the art can determine the specific meaning of the above words in the utility model in combination with the specific content of the technical scheme.

[0034] It can be understood that, with reference to Figures 1 to 7 The embodiment of the utility model discloses a laser cutting machine, which aims at providing a laser cutting equipment with reasonable structure, convenient operation, high processing efficiency and high precision, and is particularly suitable for accurate cutting processing of various workpieces.

[0035] The laser cutting machine comprises a base 130, a shell 100, a cutting assembly 400 and the like. The base 130 serves as the supporting basis of the whole equipment, and ensures the stability and reliability of the equipment. The shell 100 is connected to the base 130, and forms a closed processing space inside, which provides a safe and dust-free working environment for cutting operation. The front surface of the shell 100 is provided with a workpiece access channel 101, which is the path for the workpiece to enter the processing space for cutting treatment and to exit after cutting is completed.

[0036] The rotating table 110 is arranged in the workpiece access channel 101, and clamps for connecting and fixing workpieces are designed on the two sides of the rotating table 110. These clamps can be flexibly adjusted to adapt to workpieces of different shapes and sizes, and ensure the stability and accuracy of the workpieces in the cutting process. When the workpiece is fixed by the clamp, the rotating table 110 can be driven to rotate by a motor or other driving device, so as to smoothly send the workpiece into the processing space.

[0037] In order to further improve the safety in the processing process, the rotating table 110 is further provided with a screen assembly 120. The screen assembly 120 is in a closed state in the processing process, preventing the strong light generated by laser cutting from leaking out; and when the processing is completed, the rotating table 110 drives the screen assembly 120 to rotate, meeting the requirements of workpiece access. The screen assembly 120 can automatically close the workpiece access channel 101, effectively preventing the sparks, debris and the like generated in the cutting process from splashing and causing harm to the outside, and also reducing the noise and dust pollution in the processing process.

[0038] The cutting assembly 400 is the core part of the laser cutting machine, arranged in the machining space, responsible for completing the cutting work of the workpiece. The cutting assembly 400 mainly consists of a stand 410, a mechanical arm 420, an XY plotter 430 and a laser cutting head 440, etc. The stand 410 is a supporting structure of the mechanical arm 420, fixedly connected to the base 130. The design of the stand 410 not only ensures the stability and load-bearing capacity of the mechanical arm 420, but also provides sufficient operating space for it. The mechanical arm 420 adopts a high-precision mechanical arm with five or more axes. The fixed seat of the mechanical arm 420 is installed on the mounting platform provided at the upper end of the stand 410. The mechanical arm 420 is in an inverted form. Through the flexible movement of the mechanical arm 420, the XY plotter 430 and the laser cutting head 440 can be precisely positioned and moved in the three-dimensional space.

[0039] The XY plotter 430 is a key component for precise cutting in the cutting assembly 400, including a base 431, a sliding seat 432, an X-axis linear module 433 and a Y-axis linear module 434. The base 431 is fixedly connected to the movable end of the mechanical arm 420, serving as the mounting basis of the X-axis linear module 433 and the Y-axis linear module 434. The X-axis linear module 433 and the Y-axis linear module 434 are both installed on the base 431, and their moving directions are perpendicular to each other. Through the cooperative work of the X-axis linear module 433 and the Y-axis linear module 434, the sliding seat 432 can be driven to move precisely in the X-axis and / or the Y-axis in the plane, to realize straight line, curve, circle drawing and other operations, thereby realizing precise positioning and control of the laser cutting head 440.

[0040] The laser cutting head 440 is connected to the sliding seat 432 and is the component that actually performs the cutting work. The laser cutting head 440 is internally integrated with high-energy laser generators, focusing lenses and other elements, and can emit a high-energy density laser beam to quickly and accurately cut the workpiece. It can be understood that, in order to prevent the laser cutting head 440 from colliding with the workpiece during movement and causing damage, a collision prevention mechanism can be provided on the sliding seat 432. The function of the collision prevention mechanism is that, when a collision occurs, the laser cutting head 440 can be displaced, changed in direction, or even separated from the sliding seat 432, to prevent hard collision and avoid damage. As shown in Figure 3 and Figure 4 The collision prevention mechanism can adopt two plate members, one of which is fixed to the sliding seat 432 and the other of which is fixedly connected to the laser cutting head 440. The two plate members are connected by magnetic attraction, and ball heads and spherical grooves are provided on the opposite surfaces of the two plate members for positioning. When a collision occurs, the two plate members are separated, and the laser cutting head 440 is displaced to avoid damage. The collision prevention mechanism can also adopt a spring, a clamping structure, etc. During normal cutting work, the position of the laser cutting head 440 is stable. When a collision occurs, the laser cutting head 440 can be displaced, changed in direction, or even separated from the sliding seat 432.

[0041] In the cutting operation of the laser cutting machine, first, the workpiece to be processed is fixed on the clamp, and then the clamp is fixed on both sides of the rotating table 110. The rotating table 110 is started to drive the clamp and the workpiece to rotate, and the workpiece is smoothly sent into the processing space. When the workpiece reaches the predetermined position, the screen assembly 120 automatically closes the workpiece access passage 101.

[0042] Subsequently, the cutting assembly 400 is started, and the mechanical arm 420 drives the XY plotter 430 and the laser cutting head 440 to move to the cutting position according to the preset cutting path and parameters. Under the accurate control of the XY plotter 430, the X-axis linear module 433 and the Y-axis linear module 434 work cooperatively to drive the sliding seat 432 and the laser cutting head 440 to move accurately in the X-axis and / or Y-axis in the target plane. The laser cutting head 440 emits a high-energy laser beam to cut the workpiece according to the movement path and cutting parameters, so as to cut the workpiece into the required shape.

[0043] Through the laser cutting machine of the utility model, first, because the cutting assembly 400 adopts the structure of the combination of the mechanical arm 420 and the XY plotter 430, the laser cutting head 440 can be flexibly and accurately positioned and controlled in the three-dimensional space. During cutting, the mechanical arm 420 is in a fixed state, reducing the shaking, thereby being conducive to the stability and precision of the cutting operation. Secondly, the mechanical arm 420 adopts the inverted mounting form supported by the stand 410, effectively expanding the coverage range and the working space, so that the cutting operation is more flexible and efficient. In addition, the setting of the screen assembly 120 not only ensures the safety of the processing process, but also reduces the noise and dust pollution, providing a more comfortable and healthy working environment for the operator.

[0044] In some embodiments of the utility model, referring to Figures 5 to 7 The X-axis linear module 433 is a module capable of linear motion in the X-axis direction, and the output end is connected with a Y-axis slider 438. The Y-axis linear module 434 is a module capable of linear motion in the Y-axis direction, and the output end is connected with an X-axis slider 437. The nested linear module design makes the X-axis slider 437 move in the Y-axis direction under the drive of the Y-axis linear module 434, and the Y-axis slider 438 moves in the X-axis direction under the drive of the X-axis linear module 433.

[0045] The sliding seat 432 is provided with an X-axis sliding rail 435 and a Y-axis sliding rail 436. The X-axis sliding rail 435 is fixedly connected to one side of the sliding seat 432, and an X-axis sliding block 437 is slidingly connected to the X-axis sliding rail 435. Similarly, the Y-axis sliding rail 436 is fixedly connected to the other side of the sliding seat 432, and a Y-axis sliding block 438 is slidingly connected to the Y-axis sliding rail 436. Therefore, when the Y-axis linear module 434 is actuated, the X-axis sliding rail 435 and the X-axis sliding block 437 are pushed to move in the Y-axis direction, and the sliding seat 432 and the laser cutting head 440 can move accordingly. When the X-axis linear module 433 is actuated, the Y-axis sliding rail 436 and the Y-axis sliding block 438 are pushed to move in the X-axis direction, and the sliding seat 432 and the laser cutting head 440 can move accordingly.

[0046] The laser cutting head 440 can achieve independent or synchronous high-precision movement in the X-axis and Y-axis directions to achieve precise cutting of the workpiece. This precise movement capability in the plane enables the laser cutting machine to be suitable for cutting operations of various complex shapes, improves the cutting precision and efficiency, eliminates the cumbersome operation of clamping the workpiece multiple times, improves the processing efficiency, and reduces the cost.

[0047] Further, the sliding seat 432 is provided in a triangular structure. This structure not only has sufficient strength and stability, but also can effectively reduce the shaking and deviation of the sliding seat 432 during movement. The sliding seat 432 has a first face and a second face perpendicular to each other. The first face is a side face of the sliding seat 432, which is parallel to the X-axis direction. The X-axis sliding rail 435 is fixedly connected to the first face and slidingly connected to the X-axis sliding block 437. When the X-axis linear module 433 is actuated, the sliding seat 432 moves in the X-axis direction through the cooperation of the X-axis sliding rail 435 and the X-axis sliding block 437. The second face is another side face of the sliding seat 432, which is parallel to the Y-axis direction. The Y-axis sliding rail 436 is fixedly connected to the first face and slidingly connected to the Y-axis sliding block 438. When the Y-axis linear module 434 is actuated, the sliding seat 432 moves in the Y-axis direction through the cooperation of the Y-axis sliding rail 436 and the Y-axis sliding block 438.

[0048] Through the above structure, the sliding seat 432 can achieve stable and high-precision movement in the X-axis and Y-axis directions. At the same time, the triangular sliding seat 432 also has good torsional performance, which can effectively reduce the shaking and deviation during cutting, and improve the cutting precision and stability.

[0049] Further, the base 431 is provided with a wire fixing frame 439. The laser cutting head 440 needs to be connected to the power supply and control system during operation, so its wires 441 need to be properly fixed to avoid entanglement or damage during movement. The wire fixing frame 439 is a structure for fixing the wires 441 of the laser cutting head 440, which includes two semicircular ring members that clamp the wires 441 of the laser cutting head 440. The wire fixing frame 439 can be fixed in various ways, such as by bolt connection, buckle connection, etc. When the laser cutting head 440 moves in the X and Y directions, most of the wires 441 can remain stable, only the flexible section at the front end moves with the laser cutting head 440, avoiding cutting failure caused by entanglement or damage of the wires 441.

[0050] Referring to Figure 1 It can be understood that some workpieces will produce foul-smelling gas during cutting, such as battery cases, which contain glass fibers and produce toxic foul-smelling gas during cutting. Therefore, the shell is provided with a deodorizing mechanism, which includes an air inlet assembly 200 and an air exhaust assembly 300. The air inlet assembly 200 is connected to the top surface of the shell 100, and its main function is to supplement fresh air into the processing space to maintain air pressure balance and prevent the escape of foul-smelling gas.

[0051] Referring to Figure 8 The air inlet assembly 200 includes a shelf 210, a cover plate 220, and a plurality of air inlet windows 230. The shelf 210 is a frame structure fixed to the top surface of the shell 100, including a plurality of longitudinal and transverse intersecting square tubes, which are usually made of lightweight and strong materials such as stainless steel or aluminum alloy. The shape and size of the shelf 210 match the top surface of the shell 100 to ensure stable installation. The shelf 210 is provided with a fixed plate around it, which is connected to the shell 100 by bolts and other fasteners.

[0052] The cover plate 220 is a flat plate connected to the top of the shelf 210, and its material is also selected from lightweight and strong materials. The cover plate 220 is combined with the shelf 210 by welding, bolting or other suitable fixing methods to form a closed structure to prevent rain, dust and other impurities from entering the processing space. The cover plate 220 can be made of light-transmitting or light-blocking materials, depending on the processing requirements, and is easy to replace, with wide applicability.

[0053] The air inlet windows 230 are arranged on the cover plate 220 near the side of the front surface of the shell 100, and are arranged in several rows, which can be two rows, with a large ventilation area. The air inlet windows 230 can adopt a fine mesh structure or a shutter form to ensure smooth air circulation while preventing the entry of debris and insects. The number and size of the air inlet windows 230 can be adjusted according to the size of the processing space and the ventilation requirements.

[0054] Referring to Figure 9 , the exhaust assembly 300 is connected to the back of the housing 100, and its main function is to extract the odor gas in the processing space and filter and deodorize it. The exhaust assembly 300 includes a main frame 310, a suction cover 320, and an exhaust cover 330. The main frame 310 is a frame structure fixed to the back of the housing 100, and its shape and size match the opening on the back of the housing 100. The suction cover 320 is connected to the front side of the main frame 310, and its shape and size can be designed according to the size and shape of the processing space. The front end of the suction cover 320 is provided with a baffle 321, and the baffle 321 is provided with a plurality of suction holes. The baffle 321 can adopt a fine mesh structure or a perforated plate form to ensure that the odor gas can be effectively extracted, while avoiding the extraction of sundries. The baffle 321 is detachable for easy replacement. By adjusting the size and number of suction holes, the exhaust effect can be optimized and the deodorization efficiency can be improved. The exhaust cover 330 is connected to the rear side of the main frame 310, and the exhaust cover 330 is in the shape of a funnel, and the top is provided with a pipe joint 331 for connecting the air pipe. The air pipe guides the extracted odor gas to the external filtering equipment for treatment. The funnel-shaped design of the exhaust cover 330 helps to concentrate and guide the airflow, improving the exhaust efficiency. A powerful exhaust fan can be provided in the exhaust assembly 300 or in the downstream filtering equipment.

[0055] When performing laser cutting and other operations in the processing space, a large amount of odor gas and dust will be generated during the cutting of some workpieces. The odor gas and dust are extracted by the suction cover 320 of the exhaust assembly 300 and discharged to the external filtering equipment through the exhaust cover 330 and the air pipe for treatment, achieving the purpose of eliminating odor. At the same time, the air inlet assembly 200 supplies fresh air to the processing space through the plurality of air inlet windows 230 to maintain air pressure balance. The design of the sealing plate 220 effectively prevents the leakage of odor gas, protecting the working environment and the health of workers.

[0056] In some embodiments of the present application, the air inlet window 230 includes a panel 231 and a plug-in part 232 arranged on the lower side of the panel 231. This design allows the air inlet window 230 to be easily installed on the sealing plate 220 while ensuring good sealing performance and stability. The plug-in part 232 is arranged on the lower side of the panel 231, and its shape and size match the slot of the sealing plate 220, serving as a positioning function. The inside of the plug-in part 232 is provided with a plurality of intersecting horizontal and vertical strips arranged at a certain interval to form a grid structure as an air vent. A sealing strip can be provided between the plug-in part 232 and the sealing plate 220 to further improve the sealing performance and prevent the leakage of odor gas.

[0057] The air guide groove is arranged on the panel 231, and the air guide groove is communicated with the holes of the grid and can guide the air to enter the processing space more smoothly.

[0058] In some embodiments of the present application, the peripheral wall of the main frame 310 is provided with a first side plate 311 and a second side plate 312, which can be parallel or non-parallel, and a sealing groove is formed between the first side plate 311 and the second side plate 312. The first side plate 311 and the second side plate 312 can be fixed on the main frame 310 by welding, bolting or other mechanical connection methods. The shape and size of the sealing groove can be adjusted according to actual needs to ensure that the sealing gasket 340 can be tightly embedded therein. The material of the sealing gasket 340 is usually selected to be rubber or silicone with good elasticity and aging resistance, and also has the functions of absorbing vibration and reducing noise. The sealing gasket 340 abuts against the outer shell 100, so that the outer shell 100 and the main frame 310 are tightly connected. When the main frame 310 is installed on the outer shell 100, the sealing gasket 340 is compressed, thereby forming a continuous sealing surface, which effectively prevents the odor gas from leaking.

[0059] In some embodiments of the present application, the air suction cover 320 is a rectangular body structure, and the two sides thereof are provided with fixing frames 322 which are fixed to the outer shell 100 by fasteners (such as bolts, rivets, etc.), thereby ensuring the stability and reliability of the air suction cover 320.
