Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a feeding device for a fiber laser cutting machine. Background Technology

[0002] Fiber lasers are a new type of laser developed internationally. They output high-energy-density laser beams and focus them on the surface of a workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to melt and vaporize instantly. Automatic cutting is achieved by moving the irradiation position of the spot through a CNC mechanical system.

[0003] Fiber laser cutting technology, as a high-precision and high-efficiency modern processing method, has been widely used in the field of metal sheet processing. However, most existing fiber laser cutting machines use manual or crane loading, requiring 1-2 workers to move the metal sheet onto the laser cutting machine's worktable using a crane, forklift, or manual labor, which greatly reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for a fiber laser cutting machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for a fiber laser cutting machine, comprising a frame, a material stack assembly, a horizontal moving assembly, and a clamping assembly.

[0006] The material stacking assembly is located inside the frame and is used to stack the plates to be cut. The horizontal moving assembly is located outside the frame, and the clamping assembly is located above the horizontal moving assembly. The clamping assembly is used to clamp the plate to be cut located at the top of the material stacking assembly, and the horizontal moving assembly is used to drive the clamping assembly to move and feed the plate to be cut into the fiber laser cutting machine.

[0007] In a preferred embodiment of this invention, the stacking assembly includes a hydraulic cylinder, a stacking platform, and a limiting rod. The hydraulic cylinder is vertically fixed inside the frame, the stacking platform is fixed to the output end of the hydraulic cylinder, and the limiting rod is located at the corner of the stacking platform, passing through the stacking platform and fixed to the frame. By stacking the sheets to be cut on the stacking platform, with the top sheet parallel to the clamping assembly, after each sheet is conveyed, the hydraulic cylinder pushes the stacking platform to bring the top sheet back into contact with the clamping assembly platform.

[0008] In a preferred embodiment of this invention, the horizontal moving assembly includes a first slide rail, a first lead screw, a first slider, and a first drive motor. The first slide rail is horizontally fixed to the frame, the first lead screw is horizontally rotatably connected inside the first slide rail, the first slider is threadedly connected to the first lead screw, and the first drive motor is fixed to the end of the first slide rail. The drive shaft of the first drive motor is connected to the first lead screw. The output of the first drive motor drives the first lead screw to rotate, causing the first lead screw to drive the first slider to move, thereby using the first slider to drive the clamping assembly to translate.

[0009] In a preferred embodiment of this invention, the clamping assembly includes a second slide rail, a bidirectional lead screw, a second slider, a second drive motor, a support arm, and a clamping plate. The second slide rail is perpendicular to the first slide rail and is fixed above the first slider. The bidirectional lead screw is parallel to the second slide rail and rotatably connected inside the second slide rail. The second drive motor is fixed to the end of the second slide rail, and its drive shaft is connected to the bidirectional lead screw. Two second sliders are symmetrically threaded onto the bidirectional lead screw, and a support arm is fixed to each second slider. A clamping plate is fixed to the end of each support arm. The second drive motor drives the bidirectional lead screw to rotate, causing the two sliders to move closer or further apart. When they move closer, the sliders, through the support arms, drive the clamping plate to clamp and fix the sheet metal.

[0010] As a preferred embodiment of this invention, a rubber pad is fixed to the clamping plate. The rubber pad is provided to prevent hard contact between the clamping plate and the sheet material.

[0011] As a preferred embodiment of this invention, a reinforcing plate is fixed to the side of the first slide rail. The reinforcing plate is used to improve the stability of the first slide rail.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention eliminates the need for manual material loading by combining a stacking assembly, a horizontal moving assembly, and a clamping assembly, significantly reducing labor costs and improving work efficiency. The rubber pads of the clamping assembly buffer the contact force between the clamping plate and the sheet material, preventing scratches and indentations on the sheet material surface. The limiting rods of the stacking assembly ensure that the sheet material is stacked and aligned, avoiding sheet material loss due to misalignment during transportation. Attached Figure Description

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 utility model according to the specific circumstances.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a feeding device for a fiber laser cutting machine, including a frame 1, a material stack assembly 2, a horizontal moving assembly 3, and a clamping assembly 4.

[0019] The stacking assembly 2 is located inside the frame 1 and is used to stack the plates to be cut. The horizontal moving assembly 3 is located outside the frame 1 and the clamping assembly 4 is located above the horizontal moving assembly 3. The clamping assembly 4 is used to clamp the plate to be cut located at the top of the stacking assembly 2. The horizontal moving assembly 3 is used to drive the clamping assembly 4 to move and feed the plate to be cut into the fiber laser cutting machine.

[0020] Furthermore, the stacking assembly 2 includes a hydraulic cylinder 201, a stacking platform 202, and a limiting rod 203. The hydraulic cylinder 201 is vertically fixed inside the frame 1, the stacking platform 202 is fixed to the output end of the hydraulic cylinder 201, and the limiting rod 203 is located at the corner of the stacking platform 202, passing through the stacking platform 202 and fixed to the frame 1. By stacking the plates to be cut on the stacking platform 202, with the top plate parallel to the clamping assembly 4, after each plate is conveyed, the hydraulic cylinder 201 pushes the stacking platform 202 to bring the top plate back into contact with the clamping assembly 4 platform.

[0021] Furthermore, the horizontal moving assembly 3 includes a first slide rail 301, a first lead screw 302, a first slider 303, and a first drive motor 304. The first slide rail 301 is horizontally fixed to the frame 1. The first lead screw 302 is horizontally rotatably connected inside the first slide rail 301. The first slider 303 is threadedly connected to the first lead screw 302. The first drive motor 304 is fixed to the end of the first slide rail 301, and its drive shaft is connected to the first lead screw 302. The output of the first drive motor 304 drives the first lead screw 302 to rotate, causing the first lead screw 302 to drive the first slider 303 to move, thereby using the first slider 303 to drive the clamping assembly 4 to translate.

[0022] Furthermore, the clamping assembly 4 includes a second slide rail 401, a bidirectional lead screw 402, a second slider 403, a second drive motor 404, a support arm 405, and a clamping plate 406. The second slide rail 401 is perpendicular to the first slide rail 301 and is fixed above the first slider 303. The bidirectional lead screw 402 is parallel to the second slide rail 401 and is rotatably connected inside the second slide rail 401. The second drive motor 404 is fixed to the end of the second slide rail 401, and its drive shaft is connected to the bidirectional lead screw 402. Two second sliders 403 are symmetrically threaded onto the bidirectional lead screw 402. A support arm 405 is fixed to each second slider 403, and a clamping plate 406 is fixed to the end of the support arm 405. The second drive motor 404 drives the bidirectional lead screw 402 to rotate, causing the bidirectional lead screw 402 to drive the two sliders to move closer or further apart. When they move closer, the sliders, through the support arm 405, drive the clamping plate 406 to clamp and fix the plate.

[0023] Furthermore, a rubber pad is fixed to the clamping plate 406. The rubber pad is provided to prevent hard contact between the clamping plate 406 and the plate.

[0024] Furthermore, a reinforcing plate 3011 is fixed to the side of the first slide rail 301. The reinforcing plate 3011 is provided to improve the stability of the first slide rail 301.

[0025] In summary, during use, the plates to be cut are stacked on the stacking platform 202 of the stacking assembly 2. The limiting rod 203 at the corner ensures that the plates are stacked neatly, and initially, the top plate is parallel to the clamping assembly 4, preparing for clamping. The second drive motor 404 of the clamping assembly 4 starts, driving the bidirectional lead screw 402 to rotate, causing the two symmetrical second sliders 403 on the lead screw to move closer to each other. The sliders drive the clamping plate 406 to move synchronously through the support arm 405, clamping the top plate. The rubber pads on the clamping plate 406 prevent hard contact from damaging the plate. The first drive motor 304 of the horizontal moving assembly 3 starts, driving the first lead screw 302 in the first slide rail 301 to rotate. The first lead screw 302 drives the threaded first slider 303 to translate, and the clamping assembly 4 above the slider (along with the clamped plate) moves accordingly, feeding the plate into the fiber laser cutting machine. After a plate is conveyed, the horizontal moving component 3 returns the clamping component 4 to its original position. Then, the hydraulic cylinder 201 of the stacking component 2 pushes the stacking platform 202 upward, so that the "new topmost plate" in the stacked plates is parallel to the clamping component 4 again, waiting for the next clamping cycle.

[0026] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
