Description

Technical Field

[0001] This invention relates to the field of chassis processing, specifically to a laser cutting device for processing artificial intelligence network chassis. Background Technology

[0002] Laser cutting technology, as a high-precision and high-efficiency non-contact processing method, has been widely used in the metal manufacturing industry. It uses a high-energy-density laser beam to irradiate the surface of the workpiece, causing the material in the irradiated area to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thus achieving the cutting objective. This technology is particularly suitable for processing materials with complex contours and high hardness, playing a crucial role in industries such as sheet metal processing, automotive manufacturing, aerospace, and the production of housings for network communication equipment.

[0003] In the field of network communication and cloud computing hardware manufacturing, the chassis of AI network devices such as AI network switches, cloud server nodes, industrial network gateways, and firewalls are typically assembled from high-precision thin metal sheets. The manufacturing process of these network chassis panels requires cutting high-density, high-precision irregularly shaped holes into flat metal sheets. These holes include high-density heat dissipation arrays, fiber optic interface holes, RJ45 network ports, power interface holes, module mounting holes, and standardized ventilation grid patterns. These holes are often densely packed, require high contour precision, and have stringent industry standards for the flatness and cleanliness of the back of the sheet material. Laser cutting, due to its high flexibility, lack of mold requirements, good edge quality, and adaptability to complex contour processing, has become the preferred process for hollowing out and contour cutting of AI network chassis panels.

[0004] However, when applying general-purpose laser cutting equipment to the cutting of specific thin plates such as AI network chassis panels, existing technologies generally suffer from some long-standing and unresolved defects, directly impacting finished product quality and production efficiency. Current mainstream laser cutting methods for thin plates typically employ the following two support methods, each with significant drawbacks: The first common method is to use a solid support plate. The network chassis panel to be processed is placed flat on a solid support plate made of metal or high-temperature resistant material, and the laser head moves above the panel to cut. The main problem with this method is that after the laser beam completely penetrates the thin metal sheet, its residual energy acts on the solid support plate below. This not only causes ablation and wear on the support plate, shortening its lifespan, but more seriously, the molten metal slag melted by the laser splashes under the influence of high-pressure auxiliary gas and its own gravity. Some of the slag splashes upwards onto the cut back of the network chassis panel, where it adheres firmly after cooling, forming rough slag nodules or burrs. For AI network chassis panels that require guaranteed electromagnetic shielding performance, subsequent passivation coating, and precision interface assembly, these slag defects not only affect the appearance but also lead to misaligned interface assembly, reduced electromagnetic shielding effectiveness, and even electrical safety hazards. These are unacceptable quality defects, usually requiring an additional precision grinding or chemical cleaning process, significantly increasing manufacturing costs and production time.

[0005] The second method is to avoid molten slag splashing by using suspended supports or "micro-connection" supports. For example, comb-shaped support frames or only minimal connecting bridges are used to support the sheet metal, leaving most of the area below the cut suspended. While this method alleviates the molten slag splashing problem, it introduces new deformation risks. Network chassis panels have densely packed holes, and a single sheet often requires dozens of continuous contour cuts. When the laser performs contour cutting on a specific area of ​​the sheet, the cut portion loses support. Due to the limited rigidity of the thin metal sheet, under gravity, the cut side or the unsupported portion is prone to sinking, bending, and deformation. This deformation, occurring in real-time during processing, causes the sheet surface to lose its ideal planar state. Since the laser cutting head's focal position and cutting path are pre-programmed according to an ideal plane, localized deflection of the sheet can cause changes in the distance between the cutting head and the sheet surface, potentially leading to focal drift, incomplete cutting, or overheating. More seriously, the bending of the sheet metal can cause the subsequent cutting path to be misaligned relative to the actual position of the sheet metal. This prevents the pre-programmed cutting trajectory from accurately landing on the predetermined position of the sheet metal. This not only results in substandard interface hole accuracy, failing to meet the standardized assembly requirements of network equipment, but also causes the overall flatness of the sheet metal to exceed the tolerance, affecting the sealing performance and electromagnetic shielding effect after the chassis is assembled. Ultimately, this leads to the scrapping of the entire workpiece and serious waste of materials.

[0006] Furthermore, existing equipment also has shortcomings in terms of automation and flexibility. For the production needs of AI network equipment with multiple models, small batches, and rapid iteration, the hole layout and outline dimensions of different models of network chassis panels vary greatly. Frequent production changes mean that the CNC program for laser cutting needs to be redesigned and adjusted, and physical adjustments to the supporting tooling may be required. The preparation time for production changes is long, which affects the overall flow efficiency of the production line.

[0007] Therefore, there is a lack of a solution in the existing technology specifically for laser cutting of thin plates such as AI network chassis panels. Such a solution needs to simultaneously meet the following requirements: 1. Completely avoid contamination of the back of the plate by cutting slag; 2. Ensure that the plate remains flat throughout the cutting process to prevent bending deformation and cutting misalignment due to its own weight; 3. Have a high degree of automated loading and unloading capability; 4. Be able to quickly adapt to the changing cutting patterns of different models of network chassis panels, thereby improving production flexibility. Summary of the Invention

[0008] In view of the problems existing in laser cutting of AI network chassis panels, such as slag backflow contaminating the back of the workpiece, and the panel sinking and bending due to loss of support after dense cutting, leading to misalignment of cutting holes and excessive flatness, this invention aims to provide a novel laser cutting device specifically for processing AI network chassis panels. This device can achieve stable suspension and fixation of the panel during the cutting process, fundamentally avoiding backflow caused by slag contact with the support plate. It also ensures that the panel remains flat throughout the processing, preventing deformation, and integrates automated loading and unloading functions, improving processing accuracy and production efficiency.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting device for processing artificial intelligence network chassis, comprising a chassis panel cutting component, a chassis panel moving component, and a cutting device component.

[0010] The chassis panel cutting assembly constitutes the core workbench of the equipment, which includes a cutting table. A raw material conveyor belt for transporting raw material boards is installed above the cutting table, and a finished product conveyor belt for outputting finished products is installed below it. At least one cutting fixing seat is provided on the upper surface of the cutting table; this cutting fixing seat is the core of the innovative function of this invention.

[0011] The cutting and fixing base includes a coil frame disposed within the material trough of the cutting table. Both ends of the coil frame are connected by fixed end plates, which are slidably fitted onto a vertical guide rod fixed within the material trough. A template fixing frame is disposed above the coil frame, and a cutting template is detachably fixed within the template fixing frame using a method such as bolts. Both ends of the template fixing frame are also slidably fitted onto the vertical guide rod via lifting plates. A top plate is fixed to the top of the vertical guide rod, and a lifting cylinder is mounted on the top plate. The output end of the lifting cylinder is connected to the lifting plate for driving the template fixing frame and the cutting template to rise and fall.

[0012] An inner groove is formed on each of the opposite sides of the coil frame. Each groove houses a motor, a rotating rod driven by the motor, and a vacuum pump. The rotating rod has threaded grooves with opposite directions of rotation. Two raw material plate fixing rods are threaded onto both sides of the rotating rod. The upper surface of the raw material plate fixing rod has multiple suction holes, which are connected to the vacuum pump via flexible hoses, for adsorbing and fixing the network chassis plate placed on it. A wound coil that can be switched on and off is wound around the outer perimeter of the coil frame.

[0013] The cutting equipment assembly includes a cutting robot sliding seat mounted on one side of the cutting table, and a laser cutting robot slidably mounted thereon for performing laser cutting operations.

[0014] The chassis panel moving assembly includes a suction cup robot sliding seat mounted on the other side of the cutting table, and a suction cup robot slidably mounted thereon, for gripping the network chassis panel from the raw material board conveyor belt and transporting it to the cutting fixing seat.

[0015] Compared with the prior art, the present invention provides a laser cutting device for processing artificial intelligence network chassis, which has the following beneficial effects: 1. This laser cutting equipment for processing artificial intelligence network chassis uses a combination of lifting cylinders, magnetic coupling, and electromagnetic adsorption to lift and stably suspend the network chassis panel below the cutting template before cutting. During laser cutting, molten metal slag falls directly downwards without any physical support plate obstructing it, fundamentally eliminating the problem of slag splashing upwards and adhering to the back of the network chassis panel. This greatly improves the quality of the back of the product, eliminates the need for subsequent cleaning processes, and meets the stringent requirements of network chassis for the cleanliness and flatness of the sheet material.

[0016] 2. This laser cutting equipment for processing artificial intelligence network chassis magnetizes the network chassis panel through a magnetic field generated by a wound coil, creating a strong magnetic attraction between the panel and the iron cutting template. This force evenly and tightly stretches the panel onto the template. Even if the laser partially cuts the panel, the uncut portion remains firmly "pulled" onto the template by the magnetic force, effectively resisting sinking and bending caused by its own weight. This ensures the flatness of the panel throughout the processing, thereby guaranteeing the accuracy of the laser cutting path and avoiding problems such as misalignment of the cutting contour and substandard hole accuracy caused by deformation. This ensures the accuracy of subsequent assembly and electromagnetic shielding performance of the network chassis.

[0017] 3. This laser cutting equipment for processing AI-powered network chassis achieves automatic feeding and output of network chassis panels through the cooperation of a raw material board conveyor belt, a suction cup robotic arm, and a finished product conveyor belt. After processing, the rotating rod is driven by a controlled motor to move the two raw material board fixing rods apart, removing the support for the processed workpiece. The workpiece then automatically falls onto the finished product conveyor belt under gravity. The unloading process is smooth and reliable, requiring no manual intervention and improving production efficiency.

[0018] 4. This laser cutting equipment for processing artificial intelligence network chassis has a cutting template that is detachably mounted on a template fixing frame by bolts. When processing different models of network chassis panels, only the cutting template with the corresponding cutout pattern needs to be replaced. There is no need to rewrite the laser path program or adjust the mechanical structure, which significantly shortens the changeover time and adapts to the production needs of artificial intelligence network equipment with multiple varieties, small batches, and rapid iteration.

[0021] This invention relates to a laser cutting device for processing artificial intelligence network chassis, and more particularly to a specialized device that effectively avoids slag splashing during cutting, prevents bending and deformation of sheet metal during cutting, and achieves automated loading and unloading and precise cutting. The technical solution of this invention will be clearly and completely described below with reference to the preferred embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] Example 1: like Figures 1-8 As shown in this embodiment, a laser cutting device for processing artificial intelligence network chassis is provided. Its core design concept is to solve two major defects in the existing laser cutting of network chassis panels. First, when the laser beam penetrates the board and touches the support plate below, molten metal slag will splash and may adhere to the back of the board, affecting the assembly accuracy, electromagnetic shielding performance and quality of the finished product, and even requiring subsequent cleaning, reducing efficiency. Second, when performing dense contour cutting on the board, due to the loss of local support, the board is prone to sinking and bending due to its own weight. This deformation will cause the laser focus to deviate from the predetermined path, resulting in misalignment of holes and excessive flatness in the subsequent cutting part, producing scrap. To this end, the present invention designs an intelligent system that integrates feeding, magnetic suspension fixation, template-guided cutting and automatic unloading.

[0023] The equipment is mainly composed of three functional components: chassis panel moving component 1, chassis panel cutting component 2, and cutting equipment component 3. These three components work together to form a complete processing line. Chassis panel cutting component 2, as the core and basic platform of the equipment, is located in the central area of ​​the entire equipment. Cutting equipment component 3 is precisely installed on one side of chassis panel cutting component 2 and is specifically responsible for performing high-precision laser cutting operations. On the other side of chassis panel cutting component 2, chassis panel moving component 1 is symmetrically arranged. This component is mainly responsible for transporting the raw material sheet to be processed to the processing position and indirectly assisting in the removal of the finished product after processing.

[0024] Specifically, the main body of the chassis panel cutting assembly 2 is a robust cutting table 6. This cutting table 6 is typically welded from heavy-duty steel, with a precision-machined surface to ensure the flatness of the upper plane, providing a reference for subsequent precise positioning. On the upper surface of the cutting table 6, one or more cutting fixtures 11 can be installed according to processing requirements. These cutting fixtures 11 are key tooling that directly supports and fixes the network chassis panel 12 for cutting. They are arranged along the length or width of the cutting table 6, adapting to single-piece or small-batch continuous production. To achieve automated material flow, a raw material conveyor belt 8 is installed above the cutting table 6. This conveyor belt is typically a roller conveyor or belt conveyor, and its running height is precisely calculated to ensure... The end is located just above the side of the cutting fixture 11, so that the standard-sized network chassis board 12 transported from the upstream process or warehousing system can be accurately conveyed to the vicinity of the receiving position of the cutting fixture 11. Correspondingly, a finished product conveyor belt 7 is installed below the cutting table 6. The arrangement of the finished product conveyor belt 7 is very ingenious. It is located directly below the cutting fixture 11. Its function is to receive the processed network chassis board released from the cutting fixture 11 and falling through the cutting table 6, and smoothly transport it away from the processing area to the next process or finished product stacking area. The raw material board conveyor belt 8 and the finished product conveyor belt 7 are arranged vertically in space, realizing unidirectional material flow and greatly saving horizontal space.

[0025] The cutting equipment component 3 includes a highly rigid cutting robot sliding seat 5, which is firmly mounted on one side of the cutting table 6 by bolts or welding, typically parallel to the feed direction of the raw material conveyor belt 8. The cutting robot sliding seat 5 is equipped with a high-precision linear guide and rack, or uses a ball screw pair for transmission. A laser cutting robot 4 is connected to the above-mentioned transmission mechanism via a slider or nut, so that it can perform precise and smooth reciprocating sliding along the length of the cutting robot sliding seat 5. The laser cutting robot 4 itself is a multi-axis linkage mechanism, with a laser cutting head mounted on its end flange. The laser cutting head integrates a focusing lens, a capacitive height tracking sensor, and an auxiliary gas nozzle. A high-energy laser beam is transmitted from a distant laser generator to the cutting head through an optical fiber, and after focusing, it forms an extremely fine high-power density spot for melting metal. Under the drive of the control system, the laser cutting robot 4 can achieve complex three-dimensional movements, thereby completing the cutting of various contours.

[0026] The chassis panel moving assembly 1 is arranged opposite to the cutting equipment assembly 3 on the other side of the cutting table 6. This assembly includes a suction cup robot sliding seat 9, which is installed in a similar manner to the cutting robot sliding seat 5. It is also firmly installed on the cutting table 6. The suction cup robot sliding seat 9 is also equipped with a corresponding linear motion mechanism. A suction cup robot 10 is installed on the sliding seat and can move along its track. The suction cup robot 10 is usually a multi-joint robot or a dedicated gantry-type Cartesian coordinate robot. Its end effector is a suction cup assembly composed of multiple vacuum suction cups. These vacuum suction cups are connected to a vacuum generator through a solenoid valve. They can firmly adhere to the flat metal mesh chassis panel 12 by generating negative pressure. The working range of the suction cup robot 10 covers the area from the end of the raw material board conveyor belt 8 to the area above the cutting fixture 11, thereby enabling it to complete the actions of picking up, transferring and unloading materials.

[0027] The cutting fixture 11 is the core device that interacts directly with the network chassis board 12 and solves the problems of slag splashing and board bending. On the cutting table 6, a rectangular material groove 22 is opened through each cutting fixture 11. This material groove 22 provides space for subsequent lifting and dropping. The main body of the cutting fixture 11 is installed in this material groove 22.

[0028] Specifically, each cutting fixture 11 includes a rectangular coil frame 13, which is made of a non-magnetic material such as stainless steel or aluminum alloy. Its shape is adapted to the size of the network chassis panel 12 to be processed, typically slightly smaller than the panel. At each end of the coil frame 13, a fixed end plate 21 is fixedly connected. The fixed end plate 21 is typically made of steel plate, with its planar dimensions slightly larger than the end face of the coil frame 13, serving as a lateral limiting and connecting support. During installation, the entire coil frame 13, together with the fixed end plates 21 at both ends, is placed as a whole into the cutting table 6. Inside the material trough 22, at each end, a vertical guide rod 14 is fixedly connected. These two vertical guide rods 14 are parallel and perpendicular to the upper surface of the cutting table 6. They are firmly fixed to the bottom or side wall of the material trough 22. The fixed end plates 21 at both ends are machined with smooth guide holes, so that the fixed end plates 21 can slide and fit on the outside of the two vertical guide rods 14. In this way, the coil frame 13 together with the fixed end plates 21 can rise and fall smoothly in the vertical direction under the constraint of the vertical guide rods 14, without any horizontal offset or twisting.

[0029] Above the coil frame 13, a template fixing frame 20 is provided. The template fixing frame 20 is also a rectangular frame, and its size is similar to or slightly larger than the outer contour of the coil frame 13. A template fixing groove 18 is opened through the center of the template fixing frame 20. The cutting template 19 is placed and fixed in this template fixing groove 18. The cutting template 19 is a thin steel plate that matches the contour of the network chassis panel 12 to be processed. Its thickness is usually a few millimeters. On the cutting template 19, the corresponding hollow patterns are pre-processed according to the final required shape of the network chassis panel, such as various high-density heat dissipation hole arrays, fiber optic interface holes, network port holes, mounting holes, etc. The cutting template 19 is firmly connected to the template fixing frame 20 by multiple bolts. This detachable connection method allows the cutting template 19 to be quickly replaced according to different network chassis models, which greatly improves the flexibility of the equipment. For customized production capabilities, a lifting plate 15 is fixedly connected to the outer sides of both ends of the template fixing frame 20. The lifting plate 15 is also machined with guide holes, so that it can be slidably fitted onto the outside of the two vertical guide rods 14. At the top of the two vertical guide rods 14, a top plate 16 is fixedly connected to each of them. The top plate 16 spans across the material trough 22 and provides a mounting base for the lifting drive mechanism. A lifting cylinder 17 is installed on the upper end face of each top plate 16. The cylinder body of the lifting cylinder 17 is fixed on the top plate 16, and its piston rod extends downward. The end of the piston rod is fixedly connected to the upper end face of the lifting plate 15 below. Therefore, when the piston rod of the lifting cylinder 17 extends or retracts, it will drive the lifting plate 15 to move up and down along the vertical guide rods 14, thereby driving the template fixing frame 20 and the cutting template 19 fixedly connected to the lifting plate 15 to rise and fall together.

[0030] The coil frame 13 is not only a supporting frame but also a key component for achieving electromagnetic adsorption. A wound coil 23, composed of insulated copper wire, is tightly wound around the periphery of the coil frame 13. Wires extend from both ends of the wound coil 23 and are connected to a controllable DC power supply. When the power is on, current flows through the wound coil 23, generating a strong magnetic field inside and around the coil frame 13. The central area of ​​the coil frame 13 is used to place and fix the network chassis plate 12. On opposite sides of the inner wall of the central area of ​​the coil frame 13, there is an inner groove 25. A motor 28 is installed at one end of each inner groove 25. The motor 28 is preferably a servo motor or a stepper motor to provide precise rotation control. The output shaft of the motor 28 is fixedly connected to one end of a rotating rod 27 via a coupling. The rotating rod 27 is horizontally arranged, and its other end is rotatably connected to the other inner wall of the inner groove 25 via a bearing, allowing the rotating rod 27 to rotate freely around its own axis. A special thread structure is machined on the cylindrical outer surface of the rotating rod 27. Specifically, during rotation… On both sides of the surface of the rod 27, there are threaded grooves 26 with opposite rotation directions. For example, with the midpoint of the rotating rod 27 as the boundary, the left side has a left-hand thread and the right side has a right-hand thread. On each of the threaded grooves 26 on the surface of the rotating rod 27, a raw material plate fixing rod 24 is threadedly fitted. Since the threads on both sides rotate in opposite directions, when the rotating rod 27 rotates in one direction, the two raw material plate fixing rods 24 fitted on the threads on both sides will move towards each other synchronously, that is, move closer to each other; when the rotating rod 27 rotates in opposite directions, the two raw material plates will move towards each other. The plate fixing rods 24 will move synchronously away from each other. Each raw material plate fixing rod 24 is a slender rod with multiple suction holes 29 through the rod on its upper surface. These suction holes 29 are evenly arranged along the length of the raw material plate fixing rod 24. Inside the inner groove 25, a vacuum pump 30 is also installed. The air inlet of the vacuum pump 30 is connected to the internal air passage of the raw material plate fixing rod 24 through a flexible hose. When the vacuum pump 30 works, it will generate negative pressure inside the raw material plate fixing rod 24 and at the suction holes 29.

[0031] The specific implementation steps and principles of this invention are as follows: First, the unprocessed flat mesh housing plate 12 is placed at the starting end of the raw material board conveyor belt 8 by the preceding equipment or manually. The raw material board conveyor belt 8 starts and smoothly transports the mesh housing plate 12 to a predetermined position on one side of the cutting fixture 11, that is, the end of the conveyor belt. At this time, the mesh housing plate 12 is exactly within the grasping range of the suction cup robot 10. The control system issues a command, and the suction cup robot 10 moves along its sliding seat 9 to above the mesh housing plate 12. The suction cup assembly at the end of the suction cup robot 10 descends and contacts the surface of the mesh housing plate 12. The vacuum generator starts, and the suction cup firmly adheres to the mesh housing plate 12. Then, the suction cup robot 10 lifts the mesh housing plate 12 and moves it laterally, precisely transporting it to directly above the cutting fixture 11, that is, above the center area of ​​the coil frame 13. Then, the suction cup robot... 10. The network chassis plate 12 is lowered and placed stably on the upper surface of the two raw material plate fixing rods 24 above the coil frame 13. At this time, the network chassis plate 12 is temporarily supported by the two parallel raw material plate fixing rods 24. In order to prevent the network chassis plate 12 from sliding in subsequent actions, the control system will turn on the vacuum pump 30 at the same time or after placing the network chassis plate 12. The vacuum pump 30 operates and draws air from the inside of the raw material plate fixing rods 24 through the hose, so that negative pressure is formed at all suction holes 29. Under the action of negative pressure, the lower surface of the network chassis plate 12 is tightly adsorbed on the two raw material plate fixing rods 24, realizing the initial reliable fixation of the network chassis plate 12. This vacuum adsorption step ensures that even if the coil frame 13 moves or the equipment vibrates in the future, the network chassis plate 12 will not accidentally slip off the raw material plate fixing rods 24.

[0032] Secondly, after the network chassis plate 12 is vacuum-adsorbed and fixed, the next step is to combine it with the cutting template 19 and lift it to a suspended state. The control system controls the piston rods of the two lifting cylinders 17 to extend synchronously. The piston rods push the lifting plate 15, which in turn drives the template fixing frame 20 and the cutting template 19 on it to move downward along the vertical guide rod 14. The cutting template 19 descends until its lower surface contacts the upper surface of the network chassis plate 12 placed on the raw material plate fixing rod 24. At this time, the lifting cylinder 17 continues to apply a downward pressure to ensure that the cutting template 19 and the network chassis plate 12 are tightly attached. In this process, a key magnetic coupling link occurs. The lifting plate 15 and the fixed end plate 21 are designed to be made of permanent magnet material. For example, they can be magnetic plates with built-in permanent magnet blocks. When the lifting plate 15 moves downward under the push of the cylinder and contacts the fixed end plate 21, the magnetic force... When the lifting plate 15 and the fixed end plate 21 are in use, they will be tightly attracted together to form a rigid connection. At the same time, another more important magnetization process is also underway. The winding coil 23 wound on the coil frame 13 is now connected to an external DC power supply. The current passes through the winding coil 23, generating a concentrated strong magnetic field in the space enclosed by the coil frame 13. Since the network chassis plate 12 is usually made of ferromagnetic materials such as low carbon steel, it will be rapidly magnetized when it is in this magnetic field, and it will also become a magnetic body itself. The cutting template 19 is made of iron metal material and has good magnetic permeability. Therefore, a strong magnetic attraction will be generated between the magnetized network chassis plate 12 and the iron cutting template 19, making the two stick together tightly. The bonding force is much greater than the vacuum adsorption force. At this moment, the network chassis plate 12 is "adhere" to the bottom of the cutting template 19 by magnetic force.

[0033] After preparation, the lifting cylinder 17 reverses its movement, and the piston rod begins to retract. Since the lifting plate 15 and the fixed end plate 21 are magnetically locked, when the lifting cylinder 17 retracts, it pulls the fixed end plate 21 upward through the lifting plate 15. The fixed end plate 21 is fixedly connected to the coil frame 13, so the coil frame 13 also rises. At this moment, the network housing plate 12 is magnetically attached to the cutting template 19, which is fixed to the template fixing frame 20. The template fixing frame 20 is fixedly connected to the lifting plate 15. Therefore, the entire motion chain is as follows: the lifting cylinder 17 pulls the lifting plate 15, the lifting plate 15 drives the template fixing frame 20 and the cutting template 19, the cutting template 19 magnetically attaches to the network housing plate 12, and the network housing plate 12 vacuum-attaches the raw material plate fixing rod 24. The raw material plate fixing rod 24 is located inside the coil frame 13, and the coil frame 13 is connected to the fixed end plate. 21 is magnetically connected to the lifting plate 15. Thus, under the pulling force of the lifting cylinder 17, the network housing plate 12, the cutting template 19, the coil frame 13 below, and the fixed end plate 21 rise synchronously as a whole. The network housing plate 12 is "lifted" from the surface of the raw material plate fixing rod 24, detached from contact with the raw material plate fixing rod 24, and is only magnetically suspended below the cutting template 19. The entire assembly, including the network housing plate 12, the cutting template 19, and the coil frame 13, rises smoothly under the guidance of the vertical guide rod 14, eventually reaching a preset height suitable for laser cutting. At this height, the area below the network housing plate 12 is completely suspended without any solid support plate. This is the key to solving the problem of slag backsplashing in this invention: since the area below the cutting area is empty, the slag and metal vapor generated by laser cutting can fall directly downwards without splashing onto the back of the plate.

[0034] Next, after the network chassis panel 12 is lifted and stabilized in a suspended position, the laser cutting robot 4 begins to work. The laser emits a high-energy laser beam, which is focused and emitted by the cutting head at the end of the laser cutting robot 4. The control system drives the laser cutting robot 4 to move along the cutting robot sliding seat 5 according to the preset program, while controlling the movement axis of the cutting head itself, so that the laser focus always moves along the edge of the hollow pattern on the cutting template 19. Since the cutting template 19 is in close contact with the upper surface of the network chassis panel 12, and the hollow pattern on it is the outline to be cut, the laser beam only needs to cut the board perpendicularly, and its path is naturally defined by the boundary of the hole in the template. The high energy of the laser beam instantly melts the metal of the network chassis plate 12. Assist gas is ejected from the cutting head, blowing away the molten metal and forming a slit. Because the network chassis plate 12 is evenly attracted to the cutting template 19 by a strong electromagnetic force throughout the cutting process, the plate is subjected to uniform force and is in a taut plane. Even if one side of the workpiece is cut, the other side will not sink or bend due to loss of support, thus perfectly solving the misalignment problem caused by cutting deformation. The waste generated by cutting falls directly downwards under the action of gravity and falls into the finished product conveyor belt 7 or a special waste collection box below through the material trough 22 on the cutting table 6, without interfering with the workpiece and the cutting template.

[0035] Then, after the laser cutting robot 4 completes the cutting of all contours, the control system controls the piston rod of the lifting cylinder 17 to extend again. The piston rod pushes the lifting plate 15, the template fixing frame 20, the cutting template 19, and the network housing plate 12 and the coil frame 13 below it, which are magnetically attached to it, to move downwards synchronously until they return to the initial position. At this time, the network housing plate 12, which has been cut into the required shape, falls back above the two raw material plate fixing rods 24. Subsequently, the control system first disconnects the power supply to the winding coil 23. After the power is cut off, the magnetic field generated by the winding coil 23... The field disappears instantly. The network chassis plate 12 is made of soft magnetic material. After the external magnetic field disappears, its own magnetism also quickly fades and returns to a non-magnetic state. Once the network chassis plate 12 is demagnetized, it will no longer be magnetically attracted to the iron cutting template 19. Under the action of gravity, the network chassis plate 12 separates from the cutting template 19 and falls steadily on the surface of the two raw material plate fixing rods 24. At this time, the vacuum pump 30 may still be working, and the network chassis plate 12 may still be vacuum attracted to the raw material plate fixing rods 24, but this is only to provide additional stability during the reset process and is not necessary.

[0036] Finally, after the network chassis plate 12 is placed back into the raw material plate fixing rod 24 and demagnetization is completed, the control system shuts down the vacuum pump 30. The vacuum pump 30 stops working, the negative pressure at the suction hole 29 of the raw material plate fixing rod 24 disappears, and the network chassis plate 12 and the raw material plate fixing rod 24 are only in contact by gravity, without any adsorption force to fix them. Immediately afterwards, the control system starts the motors 28 installed in the two inner slots 25. The two motors 28 rotate synchronously in the same direction, driving the two rotating rods 27 to rotate. Since the threaded grooves 26 on both sides of each rotating rod 27 rotate in opposite directions, the rotation of the rotating rods 27 will cause the two raw material plate fixing rods 24 sleeved on them to move away from each other along the threads. That is, the left raw material plate fixing rod 24 moves to the left, and the right raw material plate fixing rod 24 moves to the right. As the motors 28 continue to run, the two raw material plate fixing rods 27... 4. Gradually separate, the gap between them increases continuously. Eventually, the two raw material plate fixing rods 24 move completely outside the outline of the network chassis plate 12, no longer providing any support for the network chassis plate 12. The finished network chassis plate 12, having lost its support, falls vertically through the gap left between the two raw material plate fixing rods 24 under the action of gravity. The network chassis plate 12 passes through the square hole in the middle of the coil frame 13, then through the material groove 22 on the cutting table 6, and lands precisely on the finished product conveyor belt 7 located directly below the cutting table 6. The finished product conveyor belt 7 starts, smoothly transporting the network chassis panel with all holes, grooves, and outlines cut out to the next stage, such as cleaning, bending, or assembly. At this point, a complete work cycle ends, the equipment resets, and waits for the next raw material plate to be loaded to begin a new round of automated processing.

[0037] Throughout the entire process described above, the cutting template 19 is fixed in the template fixing groove 18 of the template fixing frame 20 by bolts. When it is necessary to process another type of AI network chassis panel, the operator only needs to loosen the fixing bolts, remove the old cutting template 19, replace it with a new cutting template 19 with new contour holes, and retighten the bolts. The equipment does not require complex program reprogramming or mechanical adjustment. It can adapt to the production of new products simply by changing the template. This fully demonstrates the high flexibility and practicality of the equipment.

[0038] In summary, this invention achieves automatic feeding through the chassis panel moving component. The unique design combining a coil frame, electromagnetic adsorption, vacuum fixing, and mechanical telescopic rod within the cutting fixture enables the network chassis panel to be suspended and fixed during cutting, fundamentally avoiding slag splashing and panel bending. Combined with the precise laser cutting of the cutting equipment components and the automated unloading mechanism, this constitutes a highly efficient, high-quality, and flexible intelligent cutting system. All components work in a coordinated and logically sound manner, creatively solving the long-standing technical pain points of traditional laser cutting in the processing of AI network chassis workpieces.
