Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting workstation. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate a workpiece, causing the irradiated material to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the beam blows away the molten material, thereby cutting the workpiece. It is one of the thermal cutting methods for cutting workpieces. In current metal processing, a laser cutting stage is used to laser cut metal.

[0003] In related technologies, Chinese utility model patent with publication number CN218799898U discloses a high-efficiency laser cutting workstation, including a laser cutting worktable. A laser cutting machine is provided at the top of the laser cutting worktable, and a clamping structure is provided at the top of the laser cutting worktable. A waste collection port is provided at the front of the bottom end of the laser cutting worktable. Slide grooves are provided on both inner walls of the laser cutting worktable, and slide rods are provided on the two slide grooves. A screw rod is provided inside one of the slide grooves and is movably connected to the front and rear inner walls, and the screw rod passes through the slide rod. A motor is provided on the back of the laser cutting worktable and is drivenly connected to the screw rod. An automatic adjustment and cleaning mechanism is provided at the middle of the front end of the slide rod.

[0004] Regarding the aforementioned technologies, the workpiece is clamped and fixed using a clamping structure, and then the laser cutting machine automatically cuts the workpiece. After the workpiece is cut, the operator removes the workpiece from the clamping structure and then places the workpiece to be cut back into the clamping structure for fixing and cutting. This results in a long workpiece replacement time, thereby reducing the processing efficiency of the laser cutting machine. Summary of the Invention

[0005] To address the issue of long workpiece changeover times, which reduces the processing efficiency of laser cutting machines, this application provides a laser cutting workstation.

[0006] The laser cutting workstation provided in this application adopts the following technical solution: A laser cutting workstation includes a frame on which a laser cutting machine is mounted. A base is located within the frame, and a cutting table is mounted on the base. Multiple mounting slots are formed on one side of the top surface of the cutting table, and a drive roller is rotatably mounted in each of the multiple mounting slots. Multiple mounting slots are formed on the other side of the top surface of the cutting table, and a drive roller is rotatably mounted in each of the multiple mounting slots. A power assembly for driving the multiple drive rollers is provided on the cutting table. A fixing assembly for fixing the workpiece to be cut is provided on the cutting table. A drive mechanism for driving the cutting table to move along the length of the base is provided on the base.

[0007] By adopting the above technical solution, when a workpiece needs to be laser-cut, the workpiece is placed on multiple transmission rollers and then fixed by a fixing component. Next, a drive mechanism drives the cutting table to move towards the laser cutter, allowing the laser cutter to cut the workpiece. After the workpiece is cut, the fixing component is removed from the workpiece. Then, a power component drives multiple transmission rollers to rotate, transporting the workpiece to transmission roller 2. The drive mechanism then drives the cutting table to move away from the laser cutter, allowing the operator to place the workpiece to be cut on multiple transmission rollers. The drive mechanism then drives the cutting table to move towards the laser cutter again, at which point the cut workpiece on transmission roller 2 moves to one side of the base, making it easier for the operator to remove the cut workpiece. This reduces the workpiece replacement time and improves the cutting efficiency of the laser cutting machine.

[0008] Preferably, the power assembly includes a motor 1 disposed on the side of the cutting table, the output shaft of the motor 1 being fixedly connected to one end of one of the transmission rollers 1, and each of the multiple transmission rollers 1 having a pulley 1 at the end away from the motor 1, and a transmission belt 1 being wound around the outer circumference of two adjacent pulleys 1.

[0009] By adopting the above technical solution, after the workpiece on the first transmission roller is cut, the fixing component is removed from the workpiece, and then the first motor is started. The output shaft of the first motor drives one of the first transmission rollers to rotate, the first transmission roller drives the first pulley to rotate, and the first pulley drives the first pulley on another first transmission roller to rotate through the first transmission belt, so that multiple first transmission rollers rotate at the same time to transport the cut workpiece to the second transmission roller.

[0010] Preferably, the top surface of the base is provided with a movable groove, the bottom surface of the cutting table is fixed with a movable block, the movable block is slidably disposed in the movable groove, the driving mechanism includes a screw rod first rotatably installed between the opposite inner surfaces of the movable groove, the screw rod first passes through the movable block, the screw rod first is threadedly connected to the movable block, and a motor second is provided at one end of the base, the output shaft of the motor second is fixedly connected to one end of the screw rod first.

[0011] By adopting the above technical solution, when the workpiece to be cut is placed on the first transmission roller and fixed by the fixing component, the second motor is started. The output shaft of the second motor drives the first screw to rotate, the first screw drives the moving block to move, and the moving block drives the cutting table to move, so that the cutting table moves the workpiece toward the laser cutting machine for cutting. After the workpiece is cut, the fixing component is removed from the workpiece, and then the first motor is started. The first motor drives the first transmission roller to rotate, so that the first transmission roller transports the workpiece to the second transmission roller. Then the second motor is started again, and the output shaft of the second motor drives the first screw to rotate, the first screw drives the moving block to move, and the moving block drives the cutting table to move, so that the first transmission roller on the cutting table moves to one side of the base, thus facilitating the placement of the workpiece to be cut on the first transmission roller.

[0012] Preferably, side plates are fixed on both sides of the top surface of the cutting table, and the fixing assembly includes four clamping plates. The four clamping plates are respectively located at the corners of the plurality of transmission rollers. Cylinders are fixed on both sides of the two side plates that are far apart from each other. The piston rod of the cylinder passes through the side plate and is slidably connected to the side plate. The end of the piston rod away from the cylinder is fixed to the side of the clamping plate near the side plate.

[0013] By adopting the above technical solution, when the workpiece to be cut is placed on the first transmission roller, four cylinders are activated at the same time. The piston rods of the cylinders push the clamping plates to move toward the workpiece, so that the four clamping plates fix the four corners of the workpiece, thereby fixing the workpiece to be cut on the first transmission roller.

[0014] Preferably, a positioning plate is fixed on the top surface of the cutting table. The positioning plate is located on the side of the plurality of transmission rollers one away from the plurality of transmission rollers two. The side of the positioning plate near the transmission roller one is coplanar with the inner side of the two adjacent clamping plates.

[0015] By adopting the above technical solution, when the workpiece to be cut is placed on multiple transmission rollers, the side of the workpiece away from the laser cutting machine abuts against the side of the positioning plate close to the laser cutting machine, thereby positioning the fixed position of the workpiece to be cut, which in turn facilitates the four clamping plates to fix the workpiece to be cut.

[0016] Preferably, the top surface of the frame has sliding grooves on both sides, and a gantry frame is provided on the frame. The laser cutting machine is mounted on the gantry frame, and the two bottom ends of the gantry frame are slidably disposed in the two sliding grooves. The gantry frame is slidably connected to the frame along the length of the frame through the sliding grooves. A screw rod is rotatably installed between the opposite inner surfaces of the two sliding grooves. The screw rod passes through the gantry frame and is threadedly connected to the gantry frame. One end of each screw rod passes through the end face of the frame. A pulley is fixed to the end of each screw rod. A transmission belt is wound around the outer circumference of each pulley. A motor is provided on the end face of the frame away from the transmission belt. The output shaft of the motor is fixedly connected to one end of one of the screw rods.

[0017] By adopting the above technical solution, the motor three is started, and the output shaft of the motor three drives one of the screws two to rotate. The screw two drives one of the pulleys two to rotate. The pulley two drives the other pulley two to rotate through the transmission belt two, so that the two screws two rotate at the same time. The screw two drives the gantry to move along the length of the frame, so that the gantry drives the laser cutting machine to move, so that the laser cutting machine cuts the workpiece along the length of the frame.

[0018] Preferably, an infrared sensor is provided on the top surface of the frame, and a controller is provided on the side of the frame. The output terminal of the infrared sensor is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the control terminals of the four cylinders respectively.

[0019] By adopting the above technical solution, when the cutting table moves the workpiece to the cutting position, motor three is started. Motor three drives screw two to rotate, causing the two screws two to drive the gantry to move. The gantry then moves the laser cutting machine to cut the workpiece. When the gantry moves towards the workpiece, the sensor detects the gantry signal and transmits the detected signal to the controller. The controller controls the four cylinders to start simultaneously, causing the piston rods of the four cylinders to push the clamping plate to move and hold the workpiece in place. After the workpiece is cut, motor three is started again, causing motor three to drive screw two to rotate, moving the gantry to the initial position. At this time, the sensor detects the gantry signal again and transmits the signal to the controller. The controller simultaneously controls the four cylinders to start, causing the piston rods of the cylinders to drive the clamping plate away from the workpiece, thus removing the clamping plate from the workpiece. This facilitates the rotation of transmission roller one, which then transports the cut workpiece to transmission roller two.

[0020] Preferably, the top surface of the cutting table is provided with a plurality of V-shaped grooves, the V-shaped grooves are located between two adjacent transmission rollers, a push plate is slidably disposed in the V-shaped grooves, and a driving component for driving the push plate to move along the width direction of the cutting table is provided on the cutting table.

[0021] By adopting the above technical solution, multiple cutting grooves are opened on the top surface of the cutting table, so that when the laser cutter cuts the workpiece, the debris falls into the cutting grooves. Then, the drive assembly drives the push plate to move along the width direction of the cutting table, so that the push plate pushes the debris in the V-groove to both ends of the V-groove, making it easier for the staff to clean up the debris.

[0022] Preferably, the drive assembly includes a reciprocating screw rotatably mounted between the opposite inner surfaces of the V-groove, the reciprocating screw passing through the push plate and threadedly connected to the push plate, a gear one being provided at one end of the reciprocating screw, and a gear two being provided on one of the transmission rollers of two adjacent reciprocating screws, the gear one meshing with the gear two.

[0023] By adopting the above technical solution, when transmission roller one rotates, transmission roller one drives gear two to rotate, gear two drives gear one to rotate, gear one drives reciprocating screw to rotate, thereby causing the reciprocating screw to drive the push plate to move along the axial direction of the reciprocating screw.

[0024] Preferably, the cutting table has grooves on both sides of its end face, the grooves are connected to the plurality of V-shaped grooves, and a receiving box is provided in the groove.

[0025] By adopting the above technical solution, when the pusher plate pushes the debris to both ends of the V-shaped groove, the debris falls into the receiving box, which makes it easier for the staff to collect and clean the debris.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When laser cutting is required, the workpiece is placed on multiple transmission rollers and then fixed by a fixing component. The cutting table is then moved towards the laser cutter via a drive mechanism, allowing the laser cutter to cut the workpiece. After cutting, the fixing component is removed from the workpiece. The power component then drives multiple transmission rollers to rotate, transporting the workpiece to transmission roller 2. The drive mechanism then moves the cutting table away from the laser cutter, allowing the operator to place the workpiece on multiple transmission rollers. The drive mechanism then moves the cutting table towards the laser cutter again, at which point the cut workpiece on transmission roller 2 moves to one side of the base, making it easier for the operator to remove the cut workpiece. This reduces workpiece changeover time and improves the cutting efficiency of the laser cutting machine. 2. When the workpiece to be cut is placed on the first transmission roller and fixed by the fixing component, the second motor is started. The output shaft of the second motor drives the first screw to rotate, the first screw drives the moving block to move, and the moving block drives the cutting table to move, so that the cutting table moves the workpiece toward the laser cutting machine for cutting. After the workpiece is cut, the fixing component is removed from the workpiece, and the first motor is started. The first motor drives the first transmission roller to rotate, so that the first transmission roller transports the workpiece to the second transmission roller. Then the second motor is started again, and the output shaft of the second motor drives the first screw to rotate, the first screw drives the moving block to move, and the moving block drives the cutting table to move, so that the first transmission roller on the cutting table moves to one side of the base, thus making it easier to place the workpiece to be cut on the first transmission roller. 3. Start motor three. The output shaft of motor three drives one of the screws two to rotate. Screw two drives one of the pulleys two to rotate. Pulley two drives another pulley two to rotate through transmission belt two, so that both screws two rotate at the same time. Screw two drives the gantry to move along the length of the machine frame, so that the gantry moves the laser cutting machine, so that the laser cutting machine cuts the workpiece along the length of the machine frame.

[0038] Reference Figure 1 and Figure 4 The cutting table 31 has side plates 5 fixed on both sides of its top surface. Cylinders 52 are fixed on the sides of the two side plates 5 that are far apart from each other. The piston rods of the cylinders 52 pass through the side plates 5 and are slidably connected to the side plates 5. A clamping plate 51 is fixed to the end of the piston rod of the cylinder 52 that is far from the cylinder 52. A positioning plate 53 is fixed on the top surface of the cutting table 31.

[0040] The implementation principle of a laser cutting workstation according to an embodiment of this application is as follows: When a workpiece needs to be laser-cut, the operator places the workpiece on multiple transmission rollers 41, so that the side of the workpiece away from the multiple transmission rollers 46 is in contact with the side of the positioning plate 53 near the transmission rollers 41, thus fixing the workpiece in a fixed position. Then, motor 35 is started, and the output shaft of motor 35 drives screw 34 to rotate, causing screw 34 to drive moving block 33 to move. Moving block 33 drives cutting table 31 to move, causing cutting table 31 to move the workpiece towards the gantry 11, moving the workpiece to the position to be cut. Then, motor 14 is started, and motor 14 drives screw 13 to rotate, screw 13 drives pulley 15 to rotate, pulley 15 drives transmission belt 16 to rotate, and transmission belt 16 drives another pulley 15 to rotate, causing both screws 13 to rotate simultaneously. Screws 13 drive gantry 11 to move laser cutting machine 22 towards the workpiece, so that laser cutting machine 22 cuts the workpiece. When the gantry 11 moves, sensor 54 detects the gantry 11 and transmits a signal to controller 55. Controller 55 controls four cylinders 52 to start simultaneously, causing the piston rods of cylinders 52 to push the clamping plates 51 to move. This allows the four clamping plates 51 to clamp and fix the four corners of the workpiece, thereby reducing the possibility of workpiece movement during laser cutting by the laser cutting machine 22. After the workpiece is cut, motor 3 14 is started, causing motor 3 14 to drive screw 2 13 to rotate, moving the gantry 11 to its initial position. At this time, sensor 54 detects the gantry 11 signal again and transmits the signal to controller 55. Controller 55 simultaneously controls four cylinders 52 to start, causing the piston rods of cylinders 52 to move the clamping plates 51 away from the workpiece, thereby removing the clamping plates 51 from the workpiece. Then, start motor 44. The output shaft of motor 44 drives transmission roller 41 to rotate, causing transmission roller 41 to transport the workpiece to transmission roller 46. Simultaneously, start motor 35. The output shaft of motor 35 drives screw 34 to rotate. Screw 34 drives moving block 33 to move, which in turn moves cutting table 31. This moves transmission roller 41 on cutting table 31 to one side of base 3, making it easier for the operator to place the workpiece to be cut on transmission roller 41. Then, start motor 35 again. This drives screw 13 to rotate, which in turn drives moving block 33 to move, which in turn moves cutting table 31. This moves cutting table 31 and the workpiece to be cut to the cutting position. At this time, transmission roller 46 moves the cut workpiece to the other side of base 3, making it easier for the operator to remove the cut workpiece for the next process. This reduces the time for changing cut workpieces and improves the cutting efficiency of the laser gas cutting machine.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
