Description

Technical Field

[0001] This invention belongs to the technical field of metal laser cutting devices, specifically relating to a laser cutting device for processing electrical cabinet shells. Background Technology

[0002] Electrical cabinets are industrial equipment that ensure the stable operation of internal components through physical protection and environmental control systems. Their core functions include rust and corrosion protection, shock absorption, waterproofing and dustproofing, and temperature control. They are constructed primarily of cold-rolled steel plates combined with a sealed structural design.

[0003] The electrical cabinet uses cold-rolled steel plate as the main frame material, and forms a standard cabinet structure through bending and forming process. The stepped groove connection structure and double shock absorption system can reduce mechanical impact transmission by 80%. The rust-proof design incorporates an umbrella-shaped rain cover and a thickened anti-rust coating, combined with a humidity sensor inside the cabinet that links to the heating wire heating chamber to form a closed-loop moisture-proof system.

[0004] The top cooling system integrates semiconductor heat sinks and cooling fans, and the herringbone top cover improves heat dissipation efficiency by 45%. Four sets of rotating fans form an airflow circulation network, and an intelligent vent opening and closing device achieves a dynamic balance between dust prevention and heat dissipation.

[0005] During the laser cutting process, the metal casing of the electrical cabinet generates corresponding exhaust gas and dust. If it is not treated and purified in time, it will pollute the environment and be detrimental to environmental protection. The existing smoke extraction structure design is relatively simple, and the suction area is relatively fixed and cannot be adjusted. Moreover, when not in use, the suction plate is often in an open state without proper shielding and protection. During long-term operation, the air holes of the suction plate may become clogged, which is not conducive to the stable use of the device. Consequently, the exhaust gas cannot smoothly enter the treatment chamber, affecting the subsequent purification work. Summary of the Invention

[0006] The purpose of this invention is to provide a laser cutting device for processing the casing of electrical cabinets, in order to solve the technical problems that the area of ​​the smoke extraction structure is relatively fixed and cannot be adjusted accordingly, and that the suction plate is not properly shielded when not in use, resulting in air pore blockage during long-term operation, which is detrimental to the stability of the device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A laser cutting device for processing electrical cabinet housings, comprising:

[0009] The suction and dust removal mechanism includes a first motor on a frame, the output shaft of the first motor extending to a first lead screw, a first slider being screwed on the first lead screw, and a second motor being fixedly mounted on the first slider, the output shaft of the second motor being connected to a second lead screw, and a second slider being screwed on the second lead screw.

[0010] The second slider is detachably mounted with a first cylinder. The piston rod on the first cylinder is connected to a laser cutter that is compatible with it via a push rod. Both sides of the laser cutter are equipped with dust collection plates fixed on the first slider. The dust collection plates are designed with a vertical telescopic structure, and one end of the push rod is fixed to the movable end of the dust collection plate via a crossbeam.

[0011] One end of the dust collection plate is connected to a processing box via a bidirectional pipe fixed to the air pump.

[0012] Furthermore, the movable end at the bottom of the dust collection plate and the moving block are connected by a swing rod. One end of the moving block passes through the bidirectional pipe and extends to the first gear plate inside the bidirectional pipe. The outer wall of the first gear plate is driven by a rotating gear to move a second gear plate in the opposite direction. One end of the first gear plate and the second gear plate are both connected to a contact plate placed at the air hole of the bidirectional pipe.

[0013] Furthermore, the outer edge of the movable block is connected to an movable port along the length of the outer wall of the bidirectional pipe. The movable port is designed with a telescopic sealing structure. Both ends of the swing rod are mounted on the movable end of the bottom of the dust collection plate and the movable block by means of rotational connection. A workbench is provided below the laser cutter, which is placed on the frame and used to place the cabinet shell. A control valve is fixedly installed on the bidirectional pipe.

[0014] Furthermore, it also includes a particle purification mechanism placed on the treatment box, the treatment box is filled with water, and a partition is integrally formed and connected to the inner wall of the treatment box. A first filter screen and a second filter screen are respectively installed between the partition and the two sides of the inner wall of the treatment box, and the first filter screen and the second filter screen are connected by a sliding groove along the height direction of the inner wall of the treatment box.

[0015] Furthermore, the bottom of the first filter screen is mounted on a movable rod, and a cam groove is provided on the outer edge of the movable rod. The outer wall of the cam groove movably abuts against the protrusion of the rotating rod. A scraper placed on the inner wall of the processing box is connected to the outer wall of the rotating rod in the height direction through a bracket, and the bottom of the rotating rod is mounted on the bottom of the inner wall of the processing box through a bearing.

[0016] Furthermore, the outer wall of the rotating rod is fixed to the first bevel gear, and the outer wall of the first bevel gear meshes with the second bevel gear. The central shaft on the second bevel gear and the first rotating shaft inside the partition are connected by a first conveyor belt. The two sides of the bottom end of the first filter screen and the extension end of the processing box are connected by compression springs.

[0017] Furthermore, the first and second rotating shafts are connected by a second conveyor belt, which is perpendicular to the first and second conveyor belts. The outer wall of the second rotating shaft is equipped with annularly distributed rotating plates, and the second rotating shaft is provided with a first discharge port placed in a through partition. The partition has a movable cavity connected to the first and second conveyor belts.

[0018] Furthermore, the top of the second filter screen is connected to a second cylinder placed on both sides of the top of the processing box via a fixing rod. The first filter screen and the second filter screen are inclined and opposite to each other. One end of the second filter screen is provided with a second discharge port placed on the inner wall of the processing box, and a collection box connected to the second discharge port is fixedly installed on the outer wall of the processing box.

[0019] Furthermore, the first slider and the frame are provided with limiting grooves in the height and length directions, corresponding to the first lead screw and the second lead screw. The dust collection plate is provided with equidistantly distributed ventilation holes, and a cleaning brush is provided on one side of the push rod to move and abut against the outer wall of the dust collection plate.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] (1) In this invention, the screw drive mechanism can push the welding mechanism to the corresponding welding position. Under the push of the first cylinder, the laser welder can be pushed to the welding point. During the downward push of the piston rod on the first cylinder, the cleaning brush can be driven to push and clean the ventilation holes on the outer wall of the dust collection plate. It can also drive the movable end at the bottom of the dust collection plate to move downward, thereby expanding the smoke area and improving the purification effect. In addition, during the downward movement of the movable end at the bottom of the dust collection plate, under the rotational connection of the swing rod, the moving block can be driven to move horizontally. Since the moving block is fixed on the first gear plate, under the gear meshing transmission, the contact plate at the air hole on the bidirectional pipe moves back and forth, thereby effectively preventing blockage. The structural design of the bidirectional pipe itself can also play the role of bidirectional ventilation. With the back-and-forth movement of the contact plate, the stability of the device is further improved, so that the smoke and dust can effectively enter the treatment box and wait for subsequent purification work. The design is reasonable, the integrated performance is strong, and it is easy for personnel to operate.

[0022] (2) In this invention, the particulate purification mechanism utilizes the buoyancy of the floating matter in the flue gas to push the first filter screen upward, and the floating matter can enter the first discharge port. When the first filter screen moves upward, it can drive the synchronous movement of the moving rod. With the help of the compression spring, the moving rod connected to the first filter screen can automatically move back to its original position. The cam groove on the moving rod, in conjunction with the protrusion on the rotating rod, can convert the vertical movement of the moving rod into the rotational movement of the rotating rod on the bearing, thereby driving the synchronous rotation of the scraper on the bracket. In this way, the buoyancy of the particles gathered in the flue gas can directly drive the movement of the transmission component, thereby cleaning the inner wall of the treatment box, preventing the corresponding particles from adhering to the inner wall of the treatment box, ensuring the cleanliness of the inside of the treatment box, without the need for an additional power source, which is conducive to saving resources and protecting the environment. The bearing on the rotating rod not only provides the rotating rod with corresponding support force, but also allows it to rotate freely, effectively improving the automation performance of the device.

[0023] (3) In this invention, during the rotation of the rotating rod, the first bevel gear can be driven to rotate. Under the action of mechanical transmission, the rotating plate on the second rotating shaft can be driven to rotate counterclockwise, thereby pushing the particles floating at the first discharge port to the second filter screen, playing the role of material pushing. Under the pushing action of the second cylinder, the particles can slide down into the collection box by their own gravity on the inclined second filter screen, thereby completing the automatic collection function and playing an effective purification effect on the particulate matter.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference manual attached Figure 1 -Appendix Figure 9 As shown, a laser cutting device for processing electrical cabinet shells includes: a suction and dust removal mechanism 1, the suction and dust removal mechanism 1 includes a first motor 2 on a frame, the output shaft of the first motor 2 extends to a first lead screw 3, a first slider 4 is screwed on the first lead screw 3, and a second motor 5 is fixedly installed on the first slider 4, the output shaft of the second motor 5 is connected to a second lead screw 6, and a second slider 7 is screwed on the second lead screw 6;

[0037] The first cylinder 8 is detachably mounted on the second slider 7. The piston rod on the first cylinder 8 is connected to a laser cutter 10 that is compatible with it via a push rod 9. Both sides of the laser cutter 10 are equipped with dust collection plates 11 fixed on the first slider 4. The dust collection plates 11 are designed with a vertical telescopic structure, and one end of the push rod 9 is fixed to the movable end of the dust collection plate 11 via a crossbeam. One end of the dust collection plate 11 is connected to a processing box 13 via a bidirectional pipe 12 fixed on the air pump.

[0038] The screw drive mechanism can push the welding mechanism to the corresponding welding position. Under the action of the first cylinder 8, the laser welder can be pushed to the welding point. During the downward push of the piston rod on the first cylinder 8, the cleaning brush 42 can drive the ventilation hole 41 on the outer wall of the dust collection plate 11 to clean it. It can also drive the movable end at the bottom of the dust collection plate 11 to move downward, thereby expanding the smoke area and improving the purification effect. In addition, during the downward movement of the movable end at the bottom of the dust collection plate 11, under the rotational connection of the swing rod 15, the moving block 14 can be driven to move horizontally. Since the moving block 14 is fixed on the first gear plate 43, under the action of gear meshing transmission, the contact plate 18 at the air hole on the bidirectional pipe 12 moves back and forth, thereby effectively preventing blockage during the pushing process. The structural design of the bidirectional pipe 12 itself can also play the role of bidirectional ventilation. With the back-and-forth moving contact plate 18, the stability of the device is further improved, so that the smoke and dust can effectively enter the treatment box 13 for subsequent purification work. The design is reasonable, the integrated performance is strong, and it is easy for personnel to operate.

[0039] Specifically, the movable end at the bottom of the dust suction plate 11 and the moving block 14 are connected by a swing rod 15. One end of the moving block 14 passes through the bidirectional pipe 12 and extends to the first gear plate 43 inside the bidirectional pipe 12. The outer wall of the first gear plate 43 is driven by a rotating gear 16 to mesh with a second gear plate 17 that moves in the opposite direction. One end of the first gear plate 43 and the second gear plate 17 are both connected to a contact plate 18 placed at the air hole of the bidirectional pipe 12.

[0040] The outer edge of the movable block 14 is connected to an movable port along the length of the outer wall of the bidirectional pipe 12. The movable port is designed with a telescopic sealing structure. Both ends of the swing rod 15 are installed on the movable end of the bottom of the dust collection plate 11 and the movable block 14 by means of rotational connection. Below the laser cutter 10 is a workbench 19 placed on the frame and used to place the cabinet shell. A control valve is fixedly installed on the bidirectional pipe 12.

[0041] The control valve on the bidirectional pipe 12 enables unidirectional gas flow, preventing liquid backflow into the bidirectional pipe 12. During the up-and-down movement of the push rod 9, the cleaning brush 42 can clean the dust collection plate 11, preventing blockage at the external air holes. In addition, during the upward movement of the push rod 9, the bottom movable end of the dust collection plate 11 can move downward synchronously, thereby expanding the dust collection area. During the upward movement of the push rod 9, the bottom movable end of the dust collection plate 11 can move upward synchronously, thereby collecting and adjusting a certain number of air holes on the dust collection plate 11, thus achieving a corresponding dust prevention effect.

[0042] The particulate purification mechanism 20 utilizes the buoyancy of floating objects in the flue gas to push the first filter screen 22 upward, allowing the floating objects to enter the first discharge port 37. The upward movement of the first filter screen 22 drives the synchronous movement of the moving rod 24. With the help of the compression spring 33, the moving rod 24 connected to the first filter screen 22 automatically returns to its original position. The cam groove 25 on the moving rod 24, in conjunction with the protrusion 27 on the rotating rod 26, converts the vertical movement of the moving rod 24 into the rotational movement of the rotating rod 26 on the bearing, thereby driving the synchronous rotation of the scraper 28 on the support. In this way, the buoyancy of the accumulated particles in the flue gas directly drives the movement of the transmission components, thus cleaning the inner wall of the treatment box 13 and preventing particles from adhering to it, ensuring the cleanliness of the inside of the treatment box 13. No additional power source is required, which is beneficial for resource conservation and environmental protection. The bearing on the rotating rod 26 not only provides support but also allows it to rotate freely, effectively improving the automation performance of the device.

[0043] Furthermore, the exhaust gases generated during metal laser cutting mainly contain metal oxide particles, harmful gases, and ultrafine particulate matter. If these exhaust gases are discharged into the environment without effective treatment, some components may enter water bodies through sedimentation, rainwater runoff, or industrial wastewater discharge, causing environmental pollution. During laser cutting, electrical cabinets generate corresponding metal oxides, such as iron oxide and chromium oxide. These particles are extremely fine in size and have low density, allowing them to remain suspended in water for extended periods. When they accumulate, the resulting buoyancy is significant, pushing the first filter screen 22 upwards.

[0044] A laser cutting device for processing electrical cabinet housings also includes a particle purification mechanism 20 placed on a processing box 13. The processing box 13 is filled with water, and a partition 21 is integrally formed and connected to the inner wall of the processing box 13. A first filter screen 22 and a second filter screen 23 are respectively installed between the partition 21 and the two sides of the inner wall of the processing box 13, and the first filter screen 22 and the second filter screen 23 are connected by a sliding groove along the height direction of the inner wall of the processing box 13.

[0045] The bottom of the first filter screen 22 is mounted on the moving rod 24. The outer edge of the moving rod 24 is provided with a cam groove 25. The outer wall of the cam groove 25 moves against the protrusion 27 of the rotating rod 26. The outer wall of the rotating rod 26 is connected to a scraper 28 placed on the inner wall of the treatment box 13 via a bracket in the height direction. The bottom of the rotating rod 26 is mounted on the bottom of the inner wall of the treatment box 13 via a bearing.

[0046] The outer wall of the rotating rod 26 is fixed on the first bevel gear 29. The outer wall of the first bevel gear 29 meshes with the second bevel gear 30. The central shaft on the second bevel gear 30 and the first rotating shaft 31 inside the partition 21 are connected by the first conveyor belt 32. The two sides of the bottom end of the first filter screen 22 and the extension end of the processing box 13 are connected by compression springs 33.

[0047] Specifically, the first bevel gear 29 and the second bevel gear 30 are both externally connected to the housing, and the extended end of the housing is fixed to the inner wall of the processing box 13, thereby providing shielding and protection for the transmission components. The movable cavity inside the partition 21 can provide space for the movement of the first conveyor belt 32 and the second conveyor belt 35.

[0048] When the moving rod 24 moves upward, it means that the floating particles enter the first discharge port 37. Under the action of mechanical transmission, the first rotating shaft 31 rotates counterclockwise, and drives the rotating plate 36 on the second rotating shaft 34 to rotate counterclockwise synchronously, thereby playing the role of pushing the material. When the moving rod 24 moves downward, the particles do not enter the first discharge port 37. Even if the rotating plate 36 on the second rotating shaft 34 rotates clockwise, it will not push the particles onto the first filter screen 22.

[0049] Specifically, the first rotating shaft 31 and the second rotating shaft 34 are connected by a second conveyor belt 35. The first conveyor belt 32 and the second conveyor belt 35 are arranged perpendicularly. The outer wall of the second rotating shaft 34 is equipped with a ring-shaped rotating plate 36, and the second rotating shaft 34 is provided with a first discharge port 37 placed in the through partition 21. The partition 21 has a movable cavity that is connected to the first conveyor belt 32 and the second conveyor belt 35.

[0050] The top of the second filter screen 23 is connected to a second cylinder 38 located on both sides of the top of the processing box 13 via a fixing rod. The first filter screen 22 and the second filter screen 23 are inclined and opposite to each other. One end of the second filter screen 23 is provided with a second discharge port 39 located on the inner wall of the processing box 13, and a collection box 40 connected to the second discharge port 39 is fixedly installed on the outer wall of the processing box 13.

[0051] During the rotation of the rotating rod 26, it can drive the first bevel gear 29 to rotate. Under the action of mechanical transmission, it can drive the rotating plate 36 on the second rotating shaft 34 to rotate counterclockwise, thereby pushing the particles floating in the first discharge port 37 onto the second filter screen 23, playing the role of material pushing. Under the pushing action of the second cylinder 38, the particles can slide down onto the inclined second filter screen 23 by their own gravity into the collection box 40, thereby completing the automatic collection function and effectively purifying the smoke and dust particles. The first slider 4 and the frame are provided with limiting grooves corresponding to the first lead screw 3 and the second lead screw 6 in the height and length directions. The dust suction plate 11 is provided with equidistantly distributed ventilation holes 41. A cleaning brush 42 is provided on one side of the push rod 9, which moves against the outer wall of the dust suction plate 11.
