Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, and more specifically, to an automatic deburring device for laser-cut sheet metal. Background Technology

[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form holes. As the beam moves across the material, the holes continuously form narrow kerfs, completing the cutting process. For example, Chinese Patent CN202420968475.9 discloses an automatic deburring device for laser-cut sheet metal. The disclosed technical solution includes: support legs, a frame, and a laser cutter. Two sheet metal fixing devices are fixed at intervals on the other side of the gantry frame. A first grinding motor and a first grinding disc are symmetrically installed on the outer sides of both ends of the gantry frame. The device is fixedly connected to a fixed base, and a sliding groove is provided at the end of the fixed base. A movable base is slidably connected to the sliding groove. A second grinding motor and a second grinding disc are installed on the movable base. The plate fixing device includes a mounting base and a pressure plate. A threaded push rod and a fixed sleeve are installed on the mounting base. A threaded sleeve that is threadedly connected to the threaded push rod is installed on the pressure plate. A limiting post that is slidably connected to the fixed sleeve is also installed. This utility model solves the problem that existing laser cutting machines do not have a deburring function and need to be moved to a special site for processing, which is very troublesome.

[0003] However, this existing technology has certain limitations in its use. The second grinding disc can only grind the left side of the board. After grinding, the operator needs to manually flip the board to grind the right side. There is still a safety risk of being scratched by burrs during the operation, and the work efficiency needs to be further improved. Summary of the Invention

[0004] The purpose of this application is to provide an automatic deburring device for laser-cut sheet metal, which can solve the technical problems in the prior art, where the second grinding disc can only grind the left side of the sheet metal, and after grinding, the operator needs to manually flip the sheet metal to grind the right side. There is still a safety risk of being scratched by burrs during the operation, and the work efficiency needs to be further improved.

[0005] This application provides an automatic deburring device for laser-cut sheet metal, including a frame and a fixing mechanism, two first grinding mechanisms, and two second grinding mechanisms mounted on the frame. The frame is provided with a conveyor roller assembly for conveying sheet metal. A mounting frame is fixedly mounted on the top of the frame, and a laser cutter is mounted on the mounting frame. The fixing mechanism is close to the laser cutter and is used to clamp and fix the sheet metal. The first grinding mechanisms are located at the feed end of the frame, and the second grinding mechanisms are located at the discharge end of the frame.

[0006] The fixing mechanism includes two first cylinders and two clamping blocks. The piston rod of the corresponding first cylinder is connected to the corresponding clamping block. One of the first cylinders is fixedly mounted on the mounting frame, and the other first cylinder is fixedly mounted inside the bottom of the frame. The plate passes between the two clamping blocks.

[0007] The first polishing mechanism includes a first motor and a first polishing disc. The first motor is fixedly mounted on the frame, and the output shaft of the first motor is connected to the first polishing disc. The first polishing disc can be attached to the front or rear side of the plate.

[0008] The second grinding mechanism includes a second motor, a second grinding disc, a mounting plate, a screw, a screw sleeve, a third motor, and a lifting drive assembly. The mounting plate is located at the top of the frame, and a groove is provided at the bottom of the mounting plate. The screw is rotatably mounted in the groove via a bearing. The screw sleeve is threaded onto the screw and is slidably connected to the groove. The second motor is fixedly connected to the screw sleeve, and the output shaft of the second motor is connected to the second grinding disc. The second grinding disc can be fitted against the left or right side of the material. The third motor is fixedly mounted on the mounting plate, and the output shaft of the third motor is connected to the screw. The lifting drive assembly is used to drive the mounting plate to move up and down.

[0009] The lifting drive assembly includes a second cylinder, which is fixedly mounted on the frame, and the piston rod of the second cylinder is connected to the mounting plate.

[0010] The outer wall of the clamping block is provided with an anti-slip layer.

[0011] The lower end of the frame is provided with support legs.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides an automatic deburring device for laser-cut sheet metal. In use, an external drive unit rotates a conveyor roller assembly to transport the sheet metal. After loading, a first grinding mechanism grinds the front and rear sides of the sheet metal. The sheet metal is then conveyed to the laser cutter and clamped by a fixing mechanism. The laser cutter then performs laser cutting. After cutting, the right half of the sheet metal continues to be conveyed via the conveyor roller assembly, while the left half remains clamped. A second grinding mechanism then grinds the left and right sides of the right half of the sheet metal. After grinding, the sheet metal is unloaded, and the left half is released by the fixing mechanism. The left and right sides of the left half are then ground, completing the laser cutting and deburring process. This device integrates laser cutting, conveying, and four-sided grinding functions, eliminating the need for manual flipping of the sheet metal to complete grinding of all sides. This reduces safety risks, lowers operator workload, increases work efficiency, and improves production continuity. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] like Figures 1 to 3 As shown in the figure, this application provides an automatic deburring device for laser-cut sheet metal, including a frame 1 and a fixing mechanism 2, two first grinding mechanisms 3 and two second grinding mechanisms 4 disposed on the frame 1. The frame 1 is provided with a conveying roller group 11 for conveying sheet metal 5. A mounting frame 12 is fixedly disposed on the top of the frame 1. A laser cutter 13 is disposed on the mounting frame 12. The fixing mechanism 2 is close to the laser cutter 13 and is used to clamp and fix the sheet metal 5. The first grinding mechanism 3 is located at the feeding end of the frame 1, and the second grinding mechanism 4 is located at the discharging end of the frame 1.

[0032] In use, the external drive device drives the conveyor roller group 11 to rotate, thereby conveying the plate 5. After the plate 5 is loaded, the first grinding mechanism 3 grinds the front and rear sides of the plate 5. Then the plate 5 is conveyed to the laser cutter 13 and clamped and fixed by the fixing mechanism 2. Then the laser cutter 13 performs laser cutting on the plate 5. After the cutting is completed, the right half of the plate 5 is conveyed by the conveyor roller group 11. At this time, the left half of the plate 5 is still clamped and fixed by the fixing mechanism 2. Then the second grinding mechanism 4 grinds the left and right sides of the right half of the plate 5. After the grinding is completed, the plate is unloaded. Then the left half of the plate 5 is released by the fixing mechanism 2. Then the left and right sides of the left half of the plate 5 are ground, thus completing the laser cutting and deburring operation of the plate 5.

[0033] This device integrates laser cutting, conveying, and four-sided grinding functions. It can complete the grinding of all sides of the board 5 without manual flipping, reducing safety risks, reducing the labor intensity of operators, improving work efficiency, and enhancing production continuity.

[0034] like Figures 1 to 3 As shown, in this embodiment, the fixing mechanism 2 includes two first cylinders 21 and two clamping blocks 22. The piston rod of the corresponding first cylinder 21 is connected to the corresponding clamping block 22. One of the first cylinders 21 is fixedly mounted on the mounting frame 12, and the other first cylinder 21 is fixedly mounted on the inner bottom of the frame 1. The plate 5 passes through the space between the two clamping blocks 22.

[0035] During use, the two first cylinders 21 are activated synchronously, pushing the two clamping blocks 22 to apply pressure from the upper and lower surfaces of the plate 5, forming a stable clamping force in the vertical direction, thereby clamping and fixing the plate 5. After cutting, the stroke of the two first cylinders 21 is slightly adjusted so that the left half of the plate 5 is still clamped and fixed by the two clamping blocks 22, while being slightly lifted and leaving the conveyor roller group 11. This allows the conveyor roller group 11 to drive the right half of the plate 5 to continue conveying, while the left half of the plate 5 remains in its original position. The upper and lower clamping structure effectively prevents the plate 5 from shifting during the laser cutting process, improves processing accuracy, and is compatible with plates 5 of different thicknesses, achieving rapid adaptation through cylinder stroke adjustment.

[0036] like Figures 1 to 3 As shown, in this embodiment, the first polishing mechanism 3 includes a first motor 31 and a first polishing disc 32. The first motor 31 is fixedly mounted on the frame 1, and the output shaft of the first motor 31 is connected to the first polishing disc 32. The first polishing disc 32 can be attached to the front or rear side of the plate 5.

[0037] When in use, after the plate 5 is loaded, the first motor 31 is turned on to drive the first grinding disc 32 to rotate. The first grinding disc 32 contacts the edge of the plate 5 and grinds the front and rear sides of the plate 5 being conveyed.

[0038] like Figures 1 to 4 As shown, in this embodiment, the second grinding mechanism 4 includes a second motor 41, a second grinding disc 42, a mounting plate 43, a screw 44, a screw sleeve 45, a third motor 46, and a lifting drive assembly 47. The mounting plate 43 is located at the top of the frame 1, and a sliding groove 48 is provided at the bottom of the mounting plate 43. The screw 44 is rotatably mounted in the sliding groove 48 through a bearing. The screw sleeve 45 is threaded onto the screw 44, and the screw sleeve 45 is slidably connected to the sliding groove 48. The second motor 41 is fixedly connected to the screw sleeve 45, and the output shaft of the second motor 41 is connected to the second grinding disc 42. The second grinding disc 42 can be attached to the left or right side of the plate 5. The third motor 46 is fixedly mounted on the mounting plate 43, and the output shaft of the third motor 46 is connected to the screw 44. The lifting drive assembly 47 is used to drive the mounting plate 43 to move up and down.

[0039] In use, the lifting drive assembly 47 first lowers the mounting plate 43, thereby lowering the second grinding disc 42 located to the right of the plate 5 to the target height. When the conveyor roller group 11 conveys the cut plate 5 to contact the second grinding disc 42 located to the right of the plate 5, the second grinding disc 42 located to the left of the plate 5 is lowered to the target height and contacts the left side of the plate 5. Then, the second motor 41 is turned on to rotate the second grinding disc 42, and the third motor 46 is turned on to rotate the screw 44. The screw 44 moves the screw sleeve 45. The second motor 41 and the second grinding disc 42 move along the edge of the plate 5 with the screw sleeve 45, and the second grinding disc 42 can grind the left and right sides of the conveyed plate 5. After grinding, the lifting drive assembly 47 can raise the mounting plate 43, thereby moving the second grinding disc 42 away from the conveyor roller group 11 to prevent interference with the conveying and unloading of the plate 5. The screw sleeve 45 and the slide groove 48 work together to guide and limit the screw sleeve 45.

[0040] like Figures 1 to 3 As shown, in this embodiment, the lifting drive assembly 47 includes a second cylinder 471, which is fixedly mounted on the frame 1, and the piston rod of the second cylinder 471 is connected to the mounting plate 43.

[0041] When in use, the second cylinder 471 is activated to drive the mounting plate 43 to move up and down, the screw sleeve 45 moves up and down with the mounting plate 43, and the second motor 41 and the second grinding disc 42 move up and down with the screw sleeve 45.

[0042] In this embodiment, the outer wall of the clamping block 22 is provided with an anti-slip layer; the anti-slip layer can be made of rubber material, which has a high coefficient of friction, reduces the risk of slippage of the plate 5, improves clamping stability, and can also prevent the clamping block 22 from scratching the surface of the plate 5, achieving non-destructive clamping and ensuring product quality.

[0043] like Figure 2 and 3 As shown, in this embodiment, the lower end of the frame 1 is provided with a support leg 14; the support leg 14 supports and fixes the frame 1, improving the stability of use.

[0044] Working principle: When the automatic deburring device for laser-cut sheet metal provided in this application is in use, the external drive device drives the conveyor roller group 11 to rotate, thereby conveying the sheet metal 5. After the sheet metal 5 is loaded, the first motor 31 is turned on to drive the first grinding disc 32 to rotate. The first grinding disc 32 contacts the edge of the sheet metal 5 and grinds the front and rear sides of the sheet metal 5 during conveying. Then the sheet metal 5 is conveyed to the bottom of the laser cutter 13, and the two first cylinders 21 are turned on to push the two clamping blocks 22 to apply pressure from the upper and lower surfaces of the sheet metal 5, forming a stable clamping force in the vertical direction, thereby clamping and fixing the sheet metal 5. Then the laser cutter 13 performs laser cutting on the sheet metal 5. After the cutting is completed, the stroke of the two first cylinders 21 is slightly adjusted so that the left half of the sheet metal 5 is still clamped and fixed by the two clamping blocks 22, while it is slightly lifted and leaves the conveyor roller group 11, so that the conveyor roller group 11 can drive the right half of the sheet metal 5 to continue to be conveyed, while the left half of the sheet metal 5 remains in the original position.

[0045] Then, the second cylinder 471 is activated to drive the mounting plate 43 to descend. The screw sleeve 45 descends with the mounting plate 43, and the second motor 41 and the second grinding disc 42 descend with the screw sleeve 45, thereby driving the second grinding disc 42 located on the right side of the plate 5 to descend to the target height. When the conveyor roller group 11 drives the cut plate 5 to contact the second grinding disc 42 located on the right side of the plate 5, the second grinding disc 42 located on the left side of the plate 5 can be lowered to the target height and contact the left side of the plate 5. Then, the second motor 41 is activated to drive the second grinding disc 42 to rotate, and at the same time, the third motor 46 is activated to drive the screw 44 to rotate. The screw 44 drives the screw sleeve 45 to move. The second motor 41 and the second grinding disc 42 move along the edge of the plate 5 with the screw sleeve 45. The second grinding disc 42 can then grind the left and right sides of the right half of the plate 5 being conveyed.

[0046] After grinding, the mounting plate 43 can be raised by the lifting drive component 47, thereby moving the second grinding disc 42 away from the conveyor roller group 11. Then, the material is unloaded, and the left half of the plate 5 is released by the fixing mechanism 2. Then, the left and right sides of the left half of the plate 5 are ground to complete the laser cutting and deburring operation of the plate 5.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
