Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to a laser cutting platform and laser cutting equipment. Background Art

[0002] Laser cutting uses the energy released when the laser beam hits the surface of the workpiece to melt and evaporate the workpiece to achieve the purpose of cutting and engraving. In the field of metal cutting machinery, laser cutting machines have become mainstream production machinery.

[0003] There are many existing technologies for laser cutting devices, such as:

[0004] Chinese patent publication number CN111001954B discloses a laser cutting machine, which belongs to the field of laser cutting equipment. It includes a frame, a support platform is fixedly arranged on the top of the frame, the support platform includes a plurality of support plates evenly fixed along the length direction of the frame, and a cleaning mechanism for cleaning the waste on the support plate is arranged on the top of the frame; the cleaning mechanism includes a screw rod horizontally slidably connected to the top of the frame, the axial direction of the screw rod is arranged parallel to the extension direction of the support plate, and the end of the screw rod is connected to a driving component for driving the screw rod to slide horizontally along the top of the frame; the top of the screw rod is horizontally slidably connected to a fixed seat along the axial direction of the screw rod, one end of the screw rod is fixedly connected to a driving motor for driving the screw rod to rotate, a hydraulic cylinder is fixedly arranged on the top of the fixed seat, the cylinder body of the hydraulic cylinder is fixedly connected to the top of the fixed seat, the piston rod of the hydraulic cylinder extends to the bottom of the fixed seat and is fixedly connected to the fixed plate, and a shot blaster is fixedly arranged at the bottom of the fixed plate. The invention has the effect of automatically cleaning the waste on the support plate.

[0005] However, there are still some problems in actual use:

[0006] 1. At present, when the traditional detection device is used, when the laser head is used to cut the metal plate placed on the surface of the support plate, when the metal plate is cut, especially the thin plate (generally, the metal plate with a thickness of less than 3mm can be regarded as a thin plate), it is easy to cause edge warping. This is because during the laser cutting process, the laser beam is focused on the surface of the metal plate to generate high temperature, causing the metal to melt and vaporize rapidly. In this process, due to the relatively small heat capacity of the thin plate, the heat is unevenly conducted inside the plate, causing the edge of the thin plate to warp upward or downward, that is, edge warping. Edge warping will cause the cutting surface to be non-vertical, affecting the laser cutting accuracy;

[0007] 2. During the cutting process, the laser cutting machine relies on a high-energy-density laser beam focused on the surface of the workpiece to achieve cutting. If there are cutting impurities such as metal chips and slag left on the workbench, these impurities may splash up during the laser cutting process and enter the laser light path. The optical elements in the laser light path (such as focusing lenses, etc.) are very precise. Once impurities adhere to them, they will change the propagation direction and focusing effect of the laser, causing damage to the laser equipment.

[0008] In view of this, we propose a laser cutting platform and a laser cutting device. Summary of the invention

[0012] As a further improvement of the technical solution, a rotating arm is rotatably provided at the end of the fixed seat, a pressure plate is provided at the end of the rotating arm, and a torsion spring is provided between the rotating arm and the fixed seat. In a natural state, the rotating arm is located above the roller rod due to the force of the torsion spring, and the pressure plate at the end of the rotating arm limits the metal plate moving on the surface of the roller rod.

[0013] As a further improvement of the technical solution, cylinders are provided on both sides of the fixing seat, and the piston rods at the ends of the cylinders are provided with push plates, which are used to correct the position of the metal plate placed on the surface of the roller rod.

[0019] As a further improvement of the present technical solution, when the movable base plate drives the rack to move horizontally, the rack drives the gear rod to engage and rotate, and the eccentric rod at the end of the gear rod drives the striking ball to move eccentrically to knock on the surface of the workbench, thereby loosening the slag particles that have fallen inside the support plate, and the slag particles are blown by the air pipe and collected into the aggregate box.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the laser cutting platform and laser cutting equipment, a metal plate is placed on the surface of the roller rod, and the output end of the servo motor is controlled to drive the screw rod to rotate, so that the movable base plate provided on the surface of the screw rod drives the fixed seat to move in the horizontal direction. When it moves to the processing area, the output end of the motor is controlled to drive the roller rod to rotate, so that the metal plate placed on the surface of the roller rod slides off the surface of the roller rod. Since the surface of the roller rod is provided with friction particles, when the roller rod rotates, the friction particles increase the friction with the bottom of the metal plate, thereby preventing the metal plate from sliding between the surface of the roller rod and the surface of the roller rod, and reducing the labor intensity of the operators.

[0022] 2. In the laser cutting platform and laser cutting equipment, the servo laser seat is controlled to drive the laser head to the initial cutting position. The pressure wheel first fits the surface of the metal plate, and the pressure wheel squeezes the top of the metal plate. Since the pressure wheel is subjected to a reverse force, the slide bar provided on the top of the pressure wheel slides on the inner wall of the cylinder and squeezes the compression spring, so that the pressure wheel is subjected to a reverse force to maintain pressure on the top of the metal plate. When the servo laser seat drives the laser head to move along the cutting path, the pressure wheel limits the two sides of the cutting path, so that the cutting point of the metal plate is always under pressure to avoid warping of the cutting point, thereby ensuring the cutting accuracy.

[0023] 3. In the laser cutting platform and laser cutting equipment, when the rack is driven to move by the moving substrate, the rack drives the gear rod to rotate, and the gear rod drives the eccentric rod at the end to rotate when rotating, and the eccentric rod drives the striking ball to knock on the surface of the workbench when rotating, so that the slag particles remaining inside the support plate on the surface of the workbench are loosened, and the slag particles adhered and stuck inside the support plate are blown away with the air pipe to prevent the slag from splashing into the laser light path, which seriously affects the cutting accuracy and quality, so that the surface of the support plate is always kept clean, thereby improving the service life of the laser cutting device.

[0041] The present embodiment aims to provide a laser cutting platform and a laser cutting device. Figure 1-Figure 9 As shown, it includes a body 100, a workbench 101 is provided on the surface of the body 100, a support plate 105 is provided on the surface of the workbench 101, a fixed column is provided on one side of the workbench 101, a servo motor 102 is provided on one side of the fixed column, a screw rod 103 is provided at the output end of the servo motor 102, a movable substrate 104 is provided on the surface of the screw rod 103, the movable substrate 104 moves above the support plate 105, an air blowing pipe 106 and a collection box 107 are provided on both sides of the body 100, the air blowing pipe 106 is used to blow air on the surface of the support plate 105, and the slag particles dropped in the support plate 105 are blown into the collection box 107 for collection, a movable frame 200 is provided above the body 100, a servo laser seat 201 is slidably provided on the surface of the movable frame 200, and the bottom of the servo laser seat 201 A laser head 202 is provided at the bottom, and the laser head 202 is used to cut the metal plate placed on the surface of the support plate 105. A pressing component 400 is provided at the bottom of the servo laser seat 201, and the pressing component 400 is used to limit the cutting path. A feeding component 300 is provided on the surface of the movable substrate 104, and the feeding component 300 is used to adjust the position of the metal plate so that the metal plate is placed horizontally on the surface of the support plate 105. Racks 108 are provided on both sides of the bottom of the movable substrate 104, and a vibration component 500 is provided under the rack 108. When the movable substrate 104 moves, the rack 108 drives the vibration component 500 to knock on the surface of the workbench 101, so that the slag particles that fall inside the support plate 105 are loosened, and the slag particles are blown into the collection box 107 through the air pipe 106.

[0042] When cutting the metal plate, the metal plate is carried to the surface of the support plate 105 by the operator for processing. In the process of carrying the metal plate, the labor intensity is relatively high. Therefore, the feeding assembly 300 includes a fixed seat 301 arranged on the surface of the movable substrate 104, and a roller rod 302 is arranged inside the fixed seat 301. The roller rod 302 is arranged in a row. A rotation motor 303 is provided on one side of the fixed seat 301. The output end of the rotation motor 303 passes through the fixed seat 301 and connects the roller rod 302. The ends of the roller rod 302 are provided with a transmission shaft 304. The transmission shafts 304 are connected by a transmission belt. The surface of the roller rod 302 is provided with friction particles 305. The friction particles 305 are used to increase the gap between the fixed seat 301 and the metal plate. The friction force is generated by placing a metal plate on the surface of the roller rod 302, controlling the output end of the servo motor 102 to drive the screw rod 103 to rotate, so that the movable base plate 104 provided on the surface of the screw rod 103 drives the fixed seat 301 to move in the horizontal direction. When it moves to the processing area, the output end of the servo motor 303 is controlled to drive the roller rod 302 to rotate, so that the metal plate placed on the surface of the roller rod 302 slides off the surface of the roller rod 302. Since the surface of the roller rod 302 is provided with friction particles 305, when the roller rod 302 rotates, the friction particles 305 increase the friction force with the bottom of the metal plate, thereby preventing the metal plate from sliding against the surface of the roller rod 302, thereby improving the transmission efficiency of the metal plate and reducing the labor intensity of the operators.

[0043] Taking into account that during the transmission of the metal plate, when the end of the metal plate is away from the surface of the roller rod 302, the metal plate is tilted due to the action of gravity, which affects the transmission efficiency of the metal plate. Therefore, a rotating arm 306 is rotatably provided at the end of the fixed seat 301, and a pressure plate 307 is provided at the end of the rotating arm 306. A torsion spring 308 is provided between the rotating arm 306 and the fixed seat 301. In a natural state, the rotating arm 306 is above the roller rod 302 due to the force of the torsion spring 308, and the pressure plate 307 at the end of the rotating arm 306 limits the metal plate moving on the surface of the roller rod 302. By arranging the rotating arm 306 on the side wall of the fixed seat 301, the rotating arm 306 is above the roller rod 302 due to the force of the pressure plate 307, and the pressure plate 307 at the end of the rotating arm 306 limits the top of the moving metal plate, thereby reducing the metal plate from tilting and tilting due to the influence of gravity, thereby ensuring the transmission efficiency of the metal plate.

[0044] In the process of placing the metal plate, in order to ensure that the cutting path is parallel, it is necessary to adjust the position of the metal plate placed on the surface of the support plate 105 so that the metal plate is placed horizontally. Since it is necessary to use external objects to measure the level when adjusting the level, the processing efficiency is reduced. Therefore, cylinders 309 are provided on both sides of the fixed seat 301, and the piston rod at the end of the cylinder 309 is provided with a push plate 310. The push plate 310 is used to correct the position of the metal plate placed on the surface of the roller rod 302. When the metal plate is placed on the surface of the roller rod 302, the piston rod at the end of the cylinder 309 is controlled to drive the push plate 310 to move, so that the push plate 310 pushes both sides of the metal plate, so that the metal plate is at the center position of the roller rod 302, thereby quickly adjusting the horizontality of the metal plate. When the adjustment of the metal plate is completed, the metal plate is transmitted and fed by the rotation of the roller rod 302, thereby improving the processing efficiency.

[0045] Considering that when laser cutting a metal plate, when the metal plate is thin, the cut part is prone to warping, the angle between the laser beam and the warped part will change, causing the cutting surface to tilt, and the angle between the laser beam and the warped part of the plate will change, causing the cutting surface to tilt, resulting in the angle of the cutting surface offset. Since the dimensional accuracy and assembly accuracy of the parts cannot meet the requirements, the pressing component 400 includes a servo turntable 401 arranged at the bottom of the servo laser seat 201, and cylinders 402 are provided on both sides of the bottom of the servo turntable 401. A slide bar 403 is slidingly provided on the inner wall of the cylinder 402. A compression spring 404 is provided between the cylinder 402 and the slide bar 403. A pressure wheel 405 is provided at the bottom of the compression spring 404. The pressure wheel 405 is symmetrical and is located on both sides of the cutting path of the laser head 202. The pressure wheel 405 is acted upon by the compression spring 404. Press hard on both sides of the cutting path of the metal plate so that the bottom of the metal plate fits against the surface of the support plate 105. When cutting the metal thin plate, control the servo laser seat 201 to drive the laser head 202 to move to the initial cutting position. During the movement of the servo laser seat 201, the pressure wheel 405 first fits against the surface of the metal plate, and the pressure wheel 405 squeezes the top of the metal plate. Since the pressure wheel 405 is subjected to a reverse force, the slide bar 403 provided on the top of the pressure wheel 405 slides on the inner wall of the cylinder 402 and squeezes the compression spring 404, so that the pressure wheel 405 is subjected to a reverse force to maintain the pressure on the top of the metal plate. When the servo laser seat 201 drives the laser head 202 to move along the cutting path, the pressure wheel 405 limits both sides of the cutting path, so that the cutting point of the metal plate is always under pressure to avoid warping of the cutting point, thereby ensuring the cutting accuracy.

[0046] In the process of cutting the metal plate, due to the different sizes of the processed parts, in order to facilitate the limited pressing of metal plates of different thicknesses, avoid the warping of the metal plates, and improve the practicality of the device, a pull rope 406 is provided at the bottom of the slide rod 403. The pull rope 406 passes through the servo turntable 401, fits the surface of the fixed pulley 407, and is wound around the surface of the winding disk 408. The pressing strength of the pressure wheel 405 is adjusted by adjusting the free end length of the pull rope 406. When the sizes of the metal plates are different, the rotating rod is driven to rotate by rotating the turntable so that the pull rope 406 is wound around the surface of the winding disk 408 to adjust the distance between the pressure wheel 405 and the top of the metal plate. Since a ratchet 409 is provided between the rotating rod and the vertical plate, the height of the adjusted pressure wheel 405 can be limited to avoid loosening of the pull rope 406, so that the device can press and limit metal plates of different thicknesses, thereby improving the practicality of the device.

[0047] Considering that a large amount of slag particles are generated during the cutting of metal plates, the laser cutting machine relies on a high-energy-density laser beam focused on the surface of the workpiece to achieve cutting. If there are cutting impurities on the workbench 101, such as metal chips and slag, these impurities may splash up during the laser cutting process and enter the laser light path, seriously affecting the cutting accuracy and quality. Therefore, the vibration component 500 includes a base block arranged on the side of the workbench 101 close to the air blowing pipe 106, a gear rod 501 is rotatably provided at the end of the base block, an eccentric rod 502 is provided at the end of the gear rod 501, and a striking ball 503 is provided at the bottom of the eccentric rod 502. When the movable substrate 104 drives the rack 108 to move horizontally, the rack 108 drives the gear rod 501 to mesh and rotate, and the eccentric rod 502 at the end of the gear rod 501 drives the striking ball 503 to eccentrically move to knock on the surface of the workbench 101, so that the slag particles dropped on the inside of the support plate 105 are loosened, and the slag is cleaned by the air blowing pipe 106. The particles are blown and collected into the collection box 107. During the cutting process, the support plate 105 is kept blown through the air blowing pipe 106 to blow the slag particles away from the support plate 105. The output end of the servo motor 102 is controlled to drive the screw rod 103 to rotate, so that the movable base plate 104 provided on the surface of the screw rod 103 moves horizontally, and drives the metal plate placed on the surface of the feeding assembly 300 to move to the processing area. When the movable base plate 104 drives the rack 108 to move, the rack 108 drives the gear rod 501 to rotate. When the gear rod 501 rotates, it drives the eccentric rod 502 at the end to rotate. When the eccentric rod 502 rotates, it drives the striking ball 503 to knock on the surface of the workbench 101, so that the slag particles remaining inside the support plate 105 on the surface of the workbench 101 are loosened, and the air blowing pipe 106 is used to blow away the slag particles adhered and stuck inside the support plate 105, so that the surface of the support plate 105 is always kept clean, thereby improving the service life of the laser cutting device.

[0048] In summary, the working principle of the present invention is as follows: when in use, the air blowing pipe 106 is controlled to blow air on the surface of the support plate 105, and the metal plate is placed on the surface of the roller rod 302, and the output end of the servo motor 102 is controlled to drive the screw rod 103 to rotate, so that the movable base plate 104 provided on the surface of the screw rod 103 drives the fixed seat 301 to move in the horizontal direction. When it moves to the processing area, the output end of the motor 303 is controlled to drive the roller rod 302 to rotate, so that the metal plate placed on the surface of the roller rod 302 slides off the surface of the roller rod 302. Since the surface of the roller rod 302 is provided with friction particles 305, when the roller rod 302 rotates, the friction particles 305 increase the friction with the bottom of the metal plate, so as to prevent the metal plate from sliding with the surface of the roller rod 302, thereby improving the transmission efficiency of the metal plate and reducing the labor intensity of the operators.

[0049] By setting a rotating arm 306 on the side wall of the fixed seat 301, the rotating arm 306 is above the roller rod 302 under the force of the pressure plate 307, and the pressure plate 307 at the end of the rotating arm 306 limits the top of the moving metal plate, reducing the metal plate from tilting and tilting due to gravity, thereby ensuring the transmission efficiency of the metal plate;

[0050] The servo laser seat 201 is controlled to drive the laser head 202 to move to the initial cutting position. During the movement of the servo laser seat 201, the pressure wheel 405 first fits the surface of the metal plate, and the pressure wheel 405 squeezes the top of the metal plate. Since the pressure wheel 405 is subjected to a reverse force, the slide bar 403 provided on the top of the pressure wheel 405 slides on the inner wall of the cylinder 402 and squeezes the compression spring 404, so that the pressure wheel 405 is subjected to a reverse force to maintain the pressure on the top of the metal plate. When the servo laser seat 201 drives the laser head 202 to move along the cutting path, the pressure wheel 405 limits the two sides of the cutting path, so that the cutting part of the metal plate is always subjected to pressure to avoid warping of the cutting part, thereby ensuring the cutting accuracy;

[0051] During the cutting process, the support plate 105 is kept blown through the air blowing pipe 106 to blow the slag particles away from the support plate 105, and the output end of the servo motor 102 is controlled to drive the screw rod 103 to rotate, so that the movable substrate 104 provided on the surface of the screw rod 103 moves horizontally, and drives the metal plate placed on the surface of the feeding assembly 300 to move to the processing area. When the movable substrate 104 drives the rack 108 to move, the rack 108 drives the gear rod 501 to rotate, and the gear rod 501 drives the eccentric rod 502 at the end to rotate when rotating. When the eccentric rod 502 rotates, it drives the striking ball 503 to knock on the surface of the workbench 101, so that the slag particles remaining inside the support plate 105 on the surface of the workbench 101 are loosened, and the air blowing pipe 106 is used to blow away the slag particles adhered and stuck inside the support plate 105, so as to prevent the slag from splashing into the laser light path, which seriously affects the cutting accuracy and quality, so that the surface of the support plate 105 is always kept clean, and the service life of the laser cutting device is improved.
