[0063] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0064] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0066] like Figures 1 to 12 As shown, the present application proposes a laser cutting device for metal plate processing, including a workbench 100, a driving device 112 and a sheet material body 120, a moving frame 110 that can move forward and backward is provided on the workbench 100, a moving device 111 is positioned on the moving frame 110, the driving device 112 is a motor and is fixed on the moving device 111, the moving device 111 is used to drive the driving device 112 to move left and right on the moving frame 110, and also includes a cutting assembly 200, the driving device 112 is used to drive the cutting assembly 200 to make a circular motion, and cut out a circular sheet material body 120;

[0067] The cutting assembly 200 includes a fixing block 210, an air suction pipe 220, a liquid storage box 230, a drying box 240, a laser cutter 250 and a cleaning unit 260;

[0068] The fixing block 210 is a cylinder and is fixed on the driving end of the driving device 112. A fixing plate 211 is fixed on the side of the fixing block 210, and the laser cutter 250 is fixed on the free end of the fixing plate 211.

[0069] The air intake pipe 220 is fixed to one side of the laser cutter 250 through an arc plate, and the axes of the air intake pipe 220 and the fixing block 210 coincide with each other, that is, the air intake pipe 220 and the laser cutter 250 are on the same cutting path, and the air intake pipe 220 is far away from the laser cutter 250. The air intake pipe 220 is used to absorb the heat after cutting and dissipate the heat to the cut part at the same time;

[0070] An arc-shaped support plate 251 is fixed to one side of the laser cutter 250, and a liquid storage box 230 is fixed to the free end of the support plate 251. A cleaning agent is filled in the liquid storage box 230. The cleaning agent is a degreasing agent or other chemical solvents capable of removing oil stains. A liquid spray nozzle 231 is fixed to the bottom of the liquid storage box 230, and the liquid spray nozzle 231 is used to spray the cleaning agent.

[0071] The liquid storage box 230 and the laser cutter 250 are on the same cutting path, and the liquid storage box 230 is located in front of the laser cutter 250 in the forward direction, that is, the cleaning agent is sprayed out by the liquid spray nozzle 231 to clean the surface of the sheet body 120, and the laser cutter 250 cuts the cleaned part;

[0072] The air intake pipe 220 is fixed with a heat absorption pipe 221, which is used to extract air from the air intake pipe 220. The heat absorption pipe 221 is connected to an air pump, which is fixed on the fixing plate 1 211. A heat delivery pipe 222 is fixed to the air outlet end of the air pump, and the air outlet end of the heat delivery pipe 222 extends into the liquid storage box 230. The connection between the heat delivery pipe 222 and the liquid storage box 230 is airtightly fixed, which means that the cleaning agent in the liquid storage box 230 is heated by the heat delivery pipe 222, so that the cleaning effect can be improved.

[0073] The cleaning part 260 is fixed on the side of the liquid storage box 230 close to the drying box 240. The cleaning part 260 is used to wipe the cleaning agent on the surface of the sheet body 120 and remove the oil stains on the surface of the sheet body 120.

[0074] The drying box 240 is fixed on the support plate 251 near the laser cutter 250, and a distribution pipe 241 is fixed on the drying box 240. The distribution pipe 241 is communicated with the inside of the drying box 240, and the free end of the distribution pipe 241 is connected to the heat supply pipe 222. The hot air in the heat supply pipe 222 enters the drying box 240 through the distribution pipe 241. A jet pipe 243 is fixed on one side of the bottom of the drying box 240 near the liquid storage box 230. The jet pipe 243 is used to spray hot air to facilitate drying the surface of the sheet body 120 after wiping off the cleaning agent.

[0075] Specifically, if Figures 2 to 5 As shown, a purification device 223 is fixed on the heat absorption tube 221, and the purification device 223 is fixed to the fixing plate 211. The purification device 223 is used to purify large-diameter particles and gas impurities in the smoke. The particles enter the heat delivery tube 222, and the diameter of the particles is between 0.1 μm and 0.2 μm, which does not affect the laser cutting. That is, the particles enter the liquid storage box 230, and as the liquid spray nozzle 231 sprays the cleaning agent with particles, the particles continuously hit the sheet body 120, which can increase the contact strength between the cleaning agent and the sheet body 120, and improve the degreasing effect;

[0076] A filter device is fixed inside the drying box 240, and the filter device is used to intercept particles, that is, the sprayed dry gas does not contain particles. A brush 242 is fixed at the bottom of the drying box 240, and the brush 242 is in contact with the surface of the sheet body 120. The surface of the sheet body 120 is further cleaned by the brush 242 to ensure the cutting quality.

[0077] It is worth noting that the heat generated by cutting heats the cleaning agent in the liquid storage box 230, and the particles contained in the heat can increase the contact strength between the cleaning agent and the sheet body 120, thereby improving the cleaning effect.

[0078] Specifically, if Figures 2 to 6As shown, the cleaning part 260 includes a connecting plate and a gas soft bag 261. The connecting plate is fixed on the liquid storage box 230. The gas soft bag 261 is a rubber bag and is fixed on the bottom of the connecting plate.

[0079] A branch pipe 2221 is fixed on the heat delivery pipe 222, and the free end of the branch pipe 2221 extends into the gas bag 261. The connection between the branch pipe 2221 and the gas bag 261 is airtightly fixed. A cleaning cloth 262 is fixed to the bottom of the gas bag 261. The cleaning cloth 262 is used to wipe off the oil stains on the surface of the sheet body 120. A valve is fixed on the branch pipe 2221. The valve is used to control the air intake into the gas bag 261. When the cleaning cloth 262 contacts the sheet body 120, the valve is closed to stop the air intake. When the air intake into the liquid storage box 230 stops, the valve is opened to release the gas in the gas bag 261 to shrink and reset the gas bag 261.

[0080] It is worth noting that while the heat pipe 222 delivers air, it inflates the gas bag 261 through the branch pipe 2221, so that the gas bag 261 expands and drives the cleaning cloth 262 to contact the sheet body 120, thereby wiping off the dissolved oil stains on the cutting path.

[0081] In the above embodiment, the driving device 112 drives the cutting assembly 200 to rotate and cuts a circular workpiece. During the cutting process, the heat below the air intake pipe 220 is absorbed into the heat delivery pipe 222 through the heat absorption pipe 221. The heat delivery pipe 222 pressurizes the liquid storage box 230 and heats the cleaning agent in the liquid storage box 230 at the same time, so that the cleaning agent with temperature in the liquid storage box 230 is sprayed on the surface of the sheet body 120. The cleaning agent contains particles, which can increase the contact strength between the cleaning agent and the sheet body 120.

[0082] At the same time, the branch pipe 2221 is used to intake air into the gas bag 261, so that the gas bag 261 expands and drives the cleaning cloth 262 to move against the sheet body 120. As the cleaning cloth 262 moves and wipes off the dissolved oil, the hot air in the heat pipe 222 is sent to the drying box 240 through the distribution pipe 241. The dry gas is sprayed out through the jet pipe 243 to dry the residual moisture on the sheet body 120 after wiping, which can remove the oil on the cutting path, avoid splashing objects from adhering to the cutting path, and improve the cutting quality.

[0083] In some embodiments of the present application, Figures 2 to 9 As shown, the cleaning part 260 further includes a liquid soft capsule 263, the liquid soft capsule 263 is fixed at the bottom of the gas soft capsule 261, and the cleaning cloth 262 is fixed at the bottom of the liquid soft capsule 263;

[0084] The liquid bladder 263 is filled with water, and the water occupies one half of the space of the liquid bladder 263. That is to say, the water in the liquid bladder 263 is not full. During walking, the water shakes back and forth to generate vibration, which can enhance the contact force between the cleaning cloth 262 and the sheet body 120 and improve the cleaning effect.

[0085] Specifically, if Figure 8 and Fig. 9 As shown, there are multiple floats 2631 in the liquid soft capsule 263. The floats 2631 have buoyancy and a certain weight. The vibration caused by the collision is more obvious. The floats 2631 float on the water surface in the liquid soft capsule 263. When the cleaning cloth 262 contacts the sheet body 120, there is a distance between the upper part of the liquid soft capsule 263 and the floats 2631. The floats 2631 still float on the water surface, which does not affect the use of the floats 2631.

[0086] It is worth noting that the hardness of the gas capsule 261 is greater than that of the liquid capsule 263 , so the gas capsule 261 is convenient for supporting the liquid capsule 263 . In the initial state, the liquid capsule 263 and the cleaning cloth 262 are not in contact with each other.

[0087] In the above embodiment, when the cleaning cloth 262 moves on the surface of the sheet body 120, the multiple floats 2631 in the liquid capsule 263 collide with each other, thereby increasing the shaking amplitude of the water in the liquid capsule 263, causing the liquid capsule 263 to vibrate, increasing the contact force between the cleaning cloth 262 and the sheet body 120, and further improving the cleaning effect.

[0088] In some embodiments of the present application, Figures 10 to 12 As shown, the cleaning part 260 further includes a support frame 264, which is fixed to one side of the liquid storage box 230 close to the gas capsule 261, and there are two support frames 264, which are parallel to each other;

[0089] A roller 2641 is movably connected to one side of each support frame 264 close to the gas bag 261;

[0090] The cleaning cloth 262 is a long strip of cotton cloth and is located below the liquid capsule 263. There is a gap between the cleaning cloth 262 and the liquid capsule 263, leaving space for the gas capsule 261 to expand. The width of the cleaning cloth 262 is not less than the width of the liquid capsule 263. The cleaning cloth 262 can wrap the bottom of the liquid capsule 263. One end of the cleaning cloth 262 is fixed on a roller 2641, and the roller 2641 fixed with the cleaning cloth 262 is detachable, which means that after the cleaning cloth 262 is used up, the roller 2641 is removed and replaced with a new cleaning cloth 262. One end of the cleaning cloth 262 is wrapped around another roller 2641.

[0091] It is easy to understand that after the gas bladder 261 expands, it pushes the liquid bladder 263 to move downward, and after the liquid bladder 263 moves downward, it drives the cleaning cloth 262 to contact the sheet body 120.

[0092] Specifically, if Figures 10 to 12 As shown, one side of each support frame 264 away from the roller 2641 is movably connected with an adjustment rod 2643, and one adjustment rod 2643 is fixed to one roller 2641 through a connecting rod;

[0093] Two parallel guide frames 2642 are fixed on the liquid storage box 230 near the cleaning cloth 262. The cleaning cloth 262 passes through the guide frames 2642. The guide frames 2642 are used to limit the position of the cleaning cloth 262.

[0094] One of the adjusting rods 2643 is positioned on the support frame 264 through a positioning pin 2644. Each adjusting rod 2643 is provided with two through holes, and the support frame 264 is provided with two reserved holes parallel to the through holes. The positioning pin 2644 extends from the through hole of the adjusting rod 2643 into the through hole of the support frame 264. During the cleaning process, the roller 2641 will not rotate and the cleaning cloth 262 will not deviate.

[0095] In the above embodiment, when the cleaning cloth 262 in the area below the liquid soft capsule 263 is seriously dirty, the positioning pins 2644 on the two adjusting rods 2643 are removed, and one of the adjusting rods 2643 is rotated to rotate the roller 2641 fixed to the cleaning cloth 262, and the used cleaning cloth 262 is rolled up onto the roller 2641, and the unused part of the cleaning cloth 262 is moved to below the liquid soft capsule 263, and then the adjusting rod 2643 is positioned by the positioning pin 2644. The cleaning cloth 262 can be replaced without disassembly, thereby increasing the convenience of use.

[0096] In some embodiments of the present application, Figures 13 to 16 As shown, the cutting assembly 200 further includes an anti-splash portion 270, which is used to prevent the splashes of cutting from staying on the workpiece;

[0097] The anti-splashing part 270 includes a second fixing plate 2701, a heat conducting pipe 271 and a material storage box 273;

[0098] The second fixing plate 2701 is fixed to the side of the fixing block 210, and the second fixing plate 2701 is parallel to the first fixing plate 211;

[0099] The material storage box 273 is a rectangular plate body with a hollow interior, and is fixed to the bottom of the second fixed plate 2701. A plurality of nozzles 2731 are fixed on both sides of the long side of the material storage box 273, and the nozzles 2731 are connected to the interior of the material storage box 273. There is a gap between the material storage box 273 and the sheet material body 120, and the gap between the material storage box 273 and the sheet material body 120 is between 1.5 cm and 2.5 cm, which can better blow away the splashes on the surface of the sheet material body 120 in the cutting area;

[0100] One end of the heat conducting pipe 271 is fixed to the heat supply pipe 222 , and the remaining end of the heat conducting pipe 271 extends into the material storage box 273 . The connection between the heat conducting pipe 271 and the material storage box 273 is airtightly fixed.

[0101] Specifically, if Figures 13 to 16 As shown, a circular air jet seat 272 is fixed on the material storage box 273 away from the laser cutter 250, the air jet seat 272 is connected to the inside of the material storage box 273, and the air jet seat 272 coincides with the axis of the fixed block 210;

[0102] The air jet seat 272 is fixed with an air jet nozzle 2721 near the sheet body 120 . The air jet nozzle 2721 is located on the cutting path. That is, the gas ejected from the air jet nozzle 2721 can preheat the uncut area, reduce the subsequent cutting burden, and improve the cutting efficiency.

[0103] It is worth noting that after the gas enters the storage box 273, the gas can enter the air injection seat 272 and be sprayed on the uncut area through the air injection nozzle 2721. The gas contains particles, which can better increase the preheating effect.

[0104] In the above embodiment, the gas in the heat delivery pipe 222 is sent into the heat conducting pipe 271, and the gas is sent into the storage box 273 through the heat conducting pipe 271. The gas is ejected from the nozzle 2731 to form an air wall on the surface of the sheet body 120, which can prevent the splashing objects from approaching the circular sheet body 120. The ejected gas contains particles, which further increase the contact force between the airflow and the splashing objects, and prevent the splashing objects from adhering to the circular sheet body 120 after cutting, thereby reducing the difficulty of subsequent cleaning and improving processing efficiency.

[0105] In some embodiments of the present application, Figures 14 to 18 As shown, a liquid storage box 274 is fixed on the material storage box 273 away from the sheet material body 120, and an anti-splashing liquid is filled in the liquid storage box 274. The anti-splashing liquid is used to prevent splashing objects from adhering to the sheet material body 120. The anti-splashing liquid quickly forms a film within 3s to 5s. The air jet seat 272 and the material storage box 273 are separated into two independent spaces by a partition. That is to say, two independent spaces are formed between the air jet seat 272 and the material storage box 273, which are not connected to each other.

[0106] A ventilation pipe 2711 is fixed on the heat conduction pipe 271, and the free end of the ventilation pipe 2711 extends into the liquid storage box 274. A valve is fixed on the ventilation pipe 2711, and the valve is used to control the air intake in the liquid storage box 274. The air intake is stopped after the anti-splash liquid is fully sprayed on the circular sheet body 120, and the heat conduction pipe 271 extends into the jet seat 272, which means that the jet seat 272 is used for air intake, and the storage box 273 is used for liquid intake.

[0107] It is worth mentioning that the sprayed anti-splash liquid contains particles, which increases the adsorption force between the anti-splash liquid and the sheet body 120, allowing the anti-splash liquid to be better adsorbed on the sheet body 120, and the particles in the anti-splash liquid can clean the non-cutting parts on the circular sheet body 120, reducing the burden of subsequent work.

[0108] In the above embodiment, after air is taken into the heat pipe 271, the liquid storage box 274 is pressurized through the ventilation pipe 2711, so that the anti-splash liquid in the liquid storage box 274 enters the material storage box 273 and is sprayed out from the nozzle 2731. The sprayed anti-splash liquid is distributed in the form of mist on the circular sheet body 120 and quickly forms a film on the circular sheet body 120. The splashing objects splashing onto the surface treated with the anti-splash liquid can fall off naturally without forming attachments that are difficult to clean, and are not easy to damage the circular sheet body 120 after cutting, thereby improving the processing quality of the workpiece.

[0109] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
