Description

Technical Field

[0001] This utility model relates to the field of sheet material feeding technology, and in particular to an automatic sheet material feeding device for laser cutting machines. Background Technology

[0002] A laser cutting machine focuses the laser emitted from a laser into a laser beam, which irradiates the surface of a material to make the material reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the material moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting. A feeding device is required to transport the material when the laser cutting machine is working.

[0003] Existing laser cutting machine feeding devices typically use trolleys to transport sheet metal sequentially to a conveyor belt, which then transports the sheet metal to the laser cutting machine. Such devices cannot continuously and automatically transport sheet metal to the conveyor, and the sheet metal conveying speed is unstable, affecting production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic feeding device for laser cutting machine plates, which aims to improve the problem that existing devices cannot achieve continuous automatic feeding of plates to the conveying device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic feeding device for laser cutting machine sheet metal includes a support base. A first slide rail is fixedly connected to the top of the support base. A sliding plate is slidably connected to the inner wall of the first slide rail. A rotating plate is rotatably connected to the top of the sliding plate. A support arm is rotatably connected to the bottom of the sliding plate. A first motor is fixedly connected to the bottom of the support base. A rotating arm is fixedly installed at the output end of the first motor. The support arm and the rotating arm are rotatably connected. A stacking trolley is provided on the right side of the support base. A worktable is fixedly connected to the left side of the support base. A straight rack is fixedly connected to the rear side of the top of the worktable. A clamping mechanism is provided on the surface of the worktable. The clamping mechanism is used to clamp the sheet metal for laser cutting.

[0007] Preferably, the clamping mechanism includes a fixed frame, the bottom end of which is slidably connected to the worktable, a second motor is fixedly connected to the top of the fixed frame, a screw is fixedly provided at the output end of the second motor, a clamping plate is threadedly connected to the bottom end of the screw, a third motor is fixedly connected to the rear side of the fixed frame, a transmission gear is fixedly provided at the output end of the third motor, and the transmission gear is meshed with a spur rack.

[0008] Preferably, a pressure sensor is fixedly connected to the top right side of the workbench, and the surface of the pressure sensor is in contact with the plate.

[0009] Preferably, a brake wheel is fixedly connected to the bottom of the stacker vehicle, and the brake wheel is slidably connected to the surface of the support base.

[0010] Preferably, a support column is fixedly connected to the surface of the support base, a second slide rail is fixedly connected to the top of the support column, the bottom of the support column is fixedly connected to the first slide rail, and the inner wall of the second slide rail is slidably connected to the plate.

[0011] Preferably, a spring plate is fixedly connected to the left side of the stacker vehicle.

[0012] Preferably, the stacker car has an inlet slot on the right side and an outlet slot on the left side.

[0013] Preferably, the surface of the rotating plate is coated with polytetrafluoroethylene to prevent scratches from occurring when sliding on the bottom surface of the plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rotating arm drives the support arm to move, so that the sliding plate can slide back and forth along the direction of the first slide rail. When the sliding plate slides to the right end of the first slide rail, the rotating plate fixed on the sliding plate meets the plate inside the stacker and rotates. It slides from the bottom surface of the plate to the right entrance slot of the stacker. When the sliding plate slides to the left end of the first slide rail, the rotating plate pushes the plate to move to the left and leave the stacker. This achieves the purpose of automatically conveying the plate from the stacker, stabilizes the plate feeding speed, and thus improves the efficiency of laser cutting operation.

[0016] 2. In this utility model, after the plate is pushed to the right end of the first slide rail by the rotating plate, the bottom surface of the plate is in contact with the pressure sensor. The pressure sensor transmits a signal to the second motor, and the second motor starts to rotate, causing the adjusting screw to rotate inside the clamping plate, thereby clamping the plate downwards and fixing the plate. The third motor is started, and the clamping mechanism moves along the straight rack direction on the worktable, thereby adjusting the distance between the plate and the laser cutting machine, achieving the correct positioning of the plate, and avoiding the problem that the plate is prone to displacement after sliding out of the slide rail, which would cause errors during laser cutting.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4 An embodiment of this utility model provides an automatic feeding device for laser cutting machine sheet metal, including a support base. A first slide rail 2 is fixedly connected to the top of the support base 1. A sliding plate 3 is slidably connected to the inner wall of the first slide rail 2. A rotating plate 8 is rotatably connected to the top of the sliding plate 3. A support arm 12 is rotatably connected to the bottom of the sliding plate 3. A first motor 10 is fixedly connected to the bottom of the support base 1. A rotating arm 11 is fixedly provided at the output end of the first motor 10. The support arm 12 and the rotating arm 11 are rotatably connected. A stacking cart 5 is provided on the right side of the support base 1. A worktable 7 is fixedly connected to the left side of the support base 1. A straight rack 20 is fixedly connected to the rear side of the top of the worktable 7. A clamping mechanism is provided on the surface of the worktable 7. The clamping mechanism is used to clamp the sheet metal for laser cutting.

[0025] The stacking trolley 5 moves to the right end of the second slide rail 6 and is fixed in place by the spring plate 9 and the brake wheel. The first motor 10 is started, and the rotating arm 11 begins to move in a circular motion, which in turn drives the support arm 12 to move. The sliding plate 3, which is rotatably connected to the support arm 12, begins to slide back and forth along the direction of the first slide rail 2. When the sliding plate 3 slides to the right end of the first slide rail 2, the rotating plate 8 fixed on the sliding plate 3 moves to the left exit slot of the stacking trolley 5. When it encounters the plate inside the stacking trolley 5, the rotating plate 8 rotates and slides from the bottom surface of the plate to the right entrance slot of the stacking trolley 5. When the sliding plate 3 slides to the left end of the first slide rail 2, the top of the rotating plate 8 is in contact with the right side of the plate, and the bottom of the rotating plate 8 is in contact with the sliding plate 3, thereby pushing the plate to move to the left and leave the stacking trolley 5. This achieves the purpose of automatically conveying the plate from the stacking trolley 5, stabilizes the plate feeding speed, and thus improves the efficiency of laser cutting operations.

[0026] refer to Figure 3 The clamping mechanism includes a fixed frame 14, with its bottom end slidably connected to the worktable 7. A second motor 15 is fixedly connected to the top of the fixed frame 14, and a screw 17 is fixedly installed at the output end of the second motor 15. A clamping plate 18 is threadedly connected to the bottom end of the screw 17. A third motor 16 is fixedly connected to the rear side of the fixed frame 14, and a transmission gear 19 is fixedly installed at the output end of the third motor 16. The transmission gear 19 is meshed with a rack 20. When the second motor 15 is started, it causes the screw 17 to rotate inside the clamping plate 18, thereby clamping the plate downwards and fixing the plate. When the third motor 16 is started, the transmission gear 19 begins to rotate. Through the meshing connection between the transmission gear 19 and the rack 20, the clamping mechanism moves along the direction of the rack 20 on the worktable 1, thereby aligning the plate and preventing the plate from slipping off the slide rail and causing errors during laser cutting.

[0027] refer to Figure 3 A pressure sensor 13 is fixedly connected to the top right side of the workbench 7. The surface of the pressure sensor 13 is in contact with the plate. After the plate is pushed to the right end of the first slide rail 2 by the rotating plate 8, the bottom surface of the plate is in contact with the pressure sensor 13. The pressure sensor 13 transmits a signal to the clamping mechanism, thereby enabling the clamping mechanism to start operating.

[0028] refer to Figure 1 The bottom of the stacker 5 is fixedly connected to a brake wheel, which is slidably connected to the surface of the support base 1. After the stacker 5 is pushed onto the support base 1, the brake wheel is adjusted to fix the stacker 5, so as to prevent the stacker 5 from changing its position when conveying the plates inside the stacker 5, which would prevent the plates from being easily removed from the stacker 5.

[0029] refer to Figure 1A support column 4 is fixedly connected to the surface of the support base 1. A second slide rail 6 is fixedly connected to the top of the support column 4. The bottom of the support column 4 is fixedly connected to the first slide rail 2. The inner wall of the second slide rail 6 is slidably connected to the plate, thereby fixing the first slide rail 2 and the second slide rail 6 and preventing the slide rail from shaking when the plate moves, which would affect the operation of the device.

[0030] refer to Figure 4 A spring plate 9 is fixedly connected to the left side of the stacking car 5. When the stacking car 5 moves to the right end of the second slide rail 6, the spring plate 9 is squeezed and generates elastic force, which helps the stacking car 5 to be aligned with the second slide rail 6 and fixed, so as to avoid affecting the sliding of the material on the second slide rail 6.

[0031] refer to Figure 4 The stacker 5 has an inlet slot on the right side and an outlet slot on the left side, so that the rotating plate 8 can slide through the bottom surface of the plate at the outlet slot and move to the inlet slot. The rotating plate 8 moves to the left at the inlet slot and moves the plate out of the stacker 5 through the outlet slot, thus realizing the conveying of the plate inside the stacker 5.

[0032] refer to Figure 3 The rotating plate 8 is covered with polytetrafluoroethylene (PTFE). PTFE is relatively soft and has a low coefficient of friction, which helps the rotating plate 8 slide on the bottom surface of the plate while avoiding scratches.

[0033] Working principle: The stacking trolley 5 moves to the right end of the second slide rail 6 and is fixed in place by the spring plate 9 and the brake wheel. The first motor 10 is started, and the rotating arm 11 begins to move in a circular motion, which in turn drives the support arm 12 to move. The sliding plate 3, which is rotatably connected to the support arm 12, begins to slide back and forth along the direction of the first slide rail 2. When the sliding plate 3 slides to the right end of the first slide rail 2, the rotating plate 8 fixed on the sliding plate 3 moves to the left exit slot of the stacking trolley 5. When it encounters the plate inside the stacking trolley 5, the rotating plate 8 rotates and slides from the bottom surface of the plate to the right entrance slot of the stacking trolley 5. When the sliding plate 3 slides to the left end of the first slide rail 2, the top of the rotating plate 8 is in contact with the right side of the plate, and the bottom of the rotating plate 8 is in contact with the sliding plate 3, thereby pushing the plate to move to the left and leave the stacking trolley 5. This achieves the purpose of automatically conveying the plate from the stacking trolley 5, saving labor and increasing the plate feeding speed, thereby improving the efficiency of laser cutting operations.

[0034] After the plate is pushed to the right end of the first slide rail 2 by the rotating plate 8, the bottom surface of the plate is in contact with the pressure sensor 13. The pressure sensor 13 transmits a signal to the second motor 15, and the second motor 15 starts to rotate, causing the adjusting screw 17 to rotate inside the clamping plate 18, thereby clamping the plate downward and fixing it. The third motor 16 is started, and the transmission gear 19 starts to rotate. Through the meshing connection between the transmission gear 19 and the rack 20, the clamping mechanism moves along the direction of the rack 20 on the worktable 1, thereby aligning the plate and preventing the plate from slipping off the slide rail and causing errors during laser cutting.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
