Description

Technical Field

[0001] This utility model belongs to the field of sheet metal laser cutting technology, and relates to an automatic waste board removal device, particularly an automatic waste board removal device for sheet metal laser cutting. Background Technology

[0002] Leveraging the focusing capability of a high-energy laser beam, the beam is focused onto the material surface through a lens, forming a high-energy-density point. The laser energy rapidly raises the material's surface temperature to its melting or boiling point, causing the material to melt or evaporate. Simultaneously, a high-speed gas flow (such as oxygen or nitrogen) coaxial with the laser beam blows away the molten or vaporized material, creating a kerf. Under the control of a CNC system, the laser cutting head moves along a pre-set path, achieving precise cutting.

[0003] A typical laser cutting machine for sheet metal consists of a laser, a cutting head, a CNC system, a worktable, and an auxiliary gas system.

[0004] After the boards are cut, the finished boards and waste boards need to be removed. The existing removal methods are inefficient and ineffective, and cannot achieve the goal of automatic and stable removal.

[0005] Therefore, we propose an automatic waste removal device for laser cutting of sheet metal. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an automatic waste removal device for laser cutting of sheet metal. The technical problem to be solved by this utility model is: how to achieve stable and accurate positioning and transfer of the sheet metal to be cut, and to stably and conveniently unload and transfer the sheet metal to be cut.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] An automatic waste removal device for laser-cut sheet metal includes a support frame assembly and a transport and placement platform. A pushing component is provided at the rear center of the support frame assembly, and a sheet metal placement platform is rotatably mounted above the support frame assembly. The sheet metal placement platform is connected to the pushing component via a transmission. A material ejection mechanism is provided at the center of the support frame assembly, through which the sheet metal placement platform can pass. The transport and placement platform is located inside the front side of the support frame assembly, and its height is lower than that of the sheet metal placement platform. A positioning platform mechanism is provided at the rear right side of the support frame assembly. The positioning platform mechanism is equipped with a lifting positioning component and a limiting cylinder, which are located at the rear side of the positioning platform mechanism.

[0009] The working principle of this utility model is as follows: The external plate-moving device places the plate onto the positioning platform mechanism. The lifting positioning component and the limiting cylinder are used to block and position the plate to be cut. After positioning, the lifting positioning component and the limiting cylinder retract below the positioning platform mechanism, releasing the positioning of the plate to be cut. After cutting, the finished product and the waste plate are connected by a micro-connection to form the plate to be processed. The external plate-moving device continues to move the plate to be processed onto the plate-placement platform. The external plate-moving device resets, and the pushing component drives the plate-placement platform to move forward on the support frame assembly. The plate-placement platform, together with the plate to be processed, passes through the material removal mechanism. After complete penetration, the plate-placement platform, together with the plate to be processed, moves to the upper end of the transport and placement platform. The material removal mechanism moves down and blocks the rear side of the plate to be processed. The pushing component drives the plate-placement platform to move backward, and the plate to be processed falls down along the plate-placement platform onto the upper end of the transport and placement platform.

[0010] The support frame assembly includes a main crossbeam and two side crossbeams. The main crossbeam is fixedly connected to the rear ends of the two side crossbeams. Several support legs are fixed to the lower ends of the main crossbeam and the two side crossbeams. Each support leg has a crossbeam base at its lower end. Anti-collision mounting seats are fixed to the front and rear parts of the upper ends of the two side crossbeams. Anti-collision blocks are provided on the anti-collision mounting seats. The anti-collision blocks on the same side are aligned. Limiting side plates are provided in the middle of the outer side of the two side crossbeams. Several evenly distributed mounting base plates are fixed to the upper end of the left side crossbeam. The mounting base plates are located between the two anti-collision mounting seats on the same side. Tapered guide rails are fixed to the upper ends of the mounting base plates.

[0011] The above structure, with the main crossbeam, two side crossbeams, and several support legs, is used to support the plate placement platform and positioning platform mechanism. The anti-collision blocks on the same side are aligned and used to block the plate placement platform to ensure the stability of the plate placement platform's front and rear positions. The tapered guide rail is used to guide the plate placement platform to make it move stably. The crossbeam base is used to install the support frame assembly. The limiting side plate is used to fix the plate placement platform during the transportation of this device to prevent the plate placement platform from shaking.

[0012] The material pushing assembly includes a material pushing leg, a material pushing cylinder, and two mounting bases. The material pushing leg is located directly in front of the main crossbeam. A material pushing base is fixed to the lower end of the material pushing leg. One mounting base is fixed to the upper end of the material pushing leg, and the other mounting base is fixed to the middle of the upper end of the main crossbeam. The material pushing cylinder is located between the two mounting bases, and a connecting piece is fixed to the upper end of the telescopic end of the material pushing cylinder.

[0013] With the above structure, the extension end of the pusher cylinder extends to drive the connecting parts to move, thereby driving the plate placement platform to move on the upper end of the support frame assembly. The pusher base is used to install and fix the pusher assembly.

[0014] The board placement platform includes a platform frame. Several first platform brush plates are laid flat on the upper rear side of the platform frame, and several second platform brush plates are laid flat on the upper front side of the platform frame. The positions and numbers of the first and second platform brush plates correspond, with the first platform brush plates abutting against the rear side of the corresponding second platform brush plates. Several omnidirectional ball bearings are provided at the upper ends of both the first and second platform brush plates. Surrounding panels are fixed around the platform frame. Several sets of side seats, evenly distributed on the left and right sides, are fixed on the front surrounding panels. Each set of side seats contains two side seats, and each side seat has a discharge bearing seat fixed on it. A discharge brush roller is provided between the two discharge bearing seats in each set. Two guide rollers are fixed on the lower left side of the platform frame, engaging with the upper end of a tapered guide rail. Two support wheels are fixed on the lower right side of the platform frame, abutting against the upper end of a side crossbeam on the right side. A connecting seat is fixed in the middle of the lower end of the platform frame, and the connecting seat is fixedly connected to the upper end of a connecting piece.

[0015] With the above structure, several omnidirectional ball bearings are used to support the plate and facilitate stable sliding of the plate on the ball bearings. The guide rollers are engaged with the upper end of the tapered guide rail to guide the plate placement platform. The support wheel abuts against the upper end of the side crossbeam on the right side to facilitate stable movement. Each group has a discharge brush roller between the two discharge bearing seats for rolling to assist the plate in falling and being discharged. The connecting seat is fixedly connected to the upper end of the connecting piece to apply force, which is used by the pushing component to drive the plate placement platform to move on the upper end of the support frame component.

[0016] The material feeding mechanism includes a feeding frame, which is fixed in the middle of two side crossbeams. Several mounting top plates and two connecting top seats are fixed to the upper rear side of the feeding frame. A lifting cylinder is fixed to the lower end of each connecting top seat. A connecting plate is fixed to the lower end of the telescopic end of each lifting cylinder. A toothed feeding plate is fixed to the lower end of each connecting plate. A locking plate is provided between the two toothed feeding plates. A linear bearing is fixed to each mounting top plate. Several lifting slide shafts are fixed to the upper end of each toothed feeding plate. The position and number of the lifting slide shafts correspond to the linear bearings. The lifting slide shafts are slidably arranged inside the linear bearings at the corresponding positions.

[0017] Using the above structure, the pushing component drives the plate placement platform to move backward on the upper end of the support frame assembly. The plate placement platform, along with the plate to be cut, passes forward through the material ejection mechanism. After complete penetration, the plate placement platform, along with the plate to be cut, moves to the upper end of the transport and placement platform. The telescopic end of the lifting cylinder extends, driving the connecting plate downward, which in turn drives the two toothed material ejection plates downward. The locking plate ensures that the two toothed material ejection plates move downward synchronously. The lifting slide shaft is slidably set inside the linear bearing at the corresponding position to ensure that the toothed material ejection plates descend stably. The toothed material ejection plates are placed behind the plate to be cut. The pushing component drives the plate placement platform to move backward on the upper end of the support frame assembly. The toothed material ejection plates push the plate to be cut off from the plate placement platform. After the push is completed, the telescopic end of the lifting cylinder retracts.

[0018] The transport and placement platform includes a placement bracket, with several placement boards fixed to the upper end of the placement bracket, and solid wood pallets movably placed on the several placement boards.

[0019] Using the above structure, after the cut boards to be processed fall onto the top of the solid wood pallet, the workers remove the solid wood pallet from above several shelves and then place an empty solid wood pallet on top.

[0020] The positioning platform mechanism includes a positioning frame, and a number of third platform brush plates laid flat front and back are fixed at the upper end of the positioning frame. Each third platform brush plate is provided with a number of universal ball bearings. Two clearance holes are opened on the last third platform brush plate. The lifting positioning component and the limiting cylinder are both set on the last third platform brush plate. The height of the third platform brush plate is the same as the height of the first platform brush plate.

[0021] With the above structure, several universal ball bearings are used to support the plate and facilitate the plate to slide stably on the ball bearings. The lifting and positioning component and the limiting cylinder are both set on the platform brush plate on the last side and can extend from the two clearance holes to position the plate to be cut, ensuring stable and accurate cutting. After positioning is completed, the lifting and positioning component and the limiting cylinder are retracted downward from the two clearance holes.

[0022] The telescopic end of the limiting cylinder is located directly below one of the clearance holes; the lifting and positioning assembly includes a lifting cylinder, the telescopic end of which is fixed to the lower end of the third platform brush plate on the rearmost side. A mounting plate is fixed on the lifting cylinder, and a proximity sensor is fixed on the mounting plate. Two swing bearing seats are fixed in the middle of the front side of the mounting plate, and a rotatable swing rod is provided between the two swing bearing seats. A sliding limiting shaft and a touch control rod are provided on the swing rod. The end of the sliding limiting shaft is connected to the mounting plate, and a top spring is sleeved on the sliding limiting shaft. The two ends of the top spring abut against the mounting plate and the swing rod, respectively. The touch control rod is directly opposite the proximity sensor, and an ejector rod is fixed at the upper end of the swing rod. The ejector rod is located directly below another clearance hole and passes through the clearance hole.

[0023] With the above structure, the extension and retraction of the lifting cylinder's telescopic end drives the main body of the lifting cylinder to rise and fall in the opposite direction. The lifting cylinder drives the mounting plate to rise and fall, which in turn drives the proximity sensor, two swing bearing seats, sliding limit shaft, touch control rod, swing rod, and ejector rod to rise and fall synchronously. This causes the swing rod to rise and fall from the clearance hole, which in turn drives the ejector rod to rise and fall. The extension and retraction end of the limit cylinder extends from the corresponding clearance hole, and the ejector rod rises and extends from the corresponding clearance hole. After the plate abuts against the ejector rod, it pushes the swing rod to rotate on the two swing bearing seats, causing the swing rod to slide on the sliding limit shaft. The swing rod presses against the top spring, and the swing rod drives the touch control rod to move. The touch control rod abuts against the proximity sensor, controlling the equipment that places the external plate to stop pushing the plate, thus completing the plate positioning. After positioning, the lifting cylinder and limit cylinder descend and retract, and the top spring drives the swing rod to reset. At this time, the touch control rod disengages from the proximity sensor, ensuring that the equipment that places the external plate will stop pushing the plate next time.

[0024] Compared with existing technologies, this automatic waste removal device for laser cutting of sheet metal has the following advantages:

[0025] By cooperating with the support frame assembly and the board placement platform, the board placement platform can move back and forth on the support frame assembly, which facilitates quick unloading.

[0026] By cooperating with the material pushing component and the board placement platform, the material pushing component drives the board placement platform to move for unloading.

[0027] By cooperating with the material removal mechanism and the board placement platform, the cutting board to be processed can be quickly transferred to the upper part of the handling and placing platform. Unloading is stable and convenient, and the handling and placing platform facilitates rapid material discharge.

[0028] By coordinating the board placement platform and the positioning platform mechanism, the boards can be transferred quickly and stably.

[0029] The plate placement platform, in conjunction with the lifting and positioning components and the limit cylinder, is used to stably and quickly position the plate to be cut, ensuring accurate cutting and accurate transfer to the plate placement platform. Attached Figure Description

A positioning platform mechanism 43 is provided in the rear right side of the support frame assembly 1. A lifting positioning assembly 44 and a limiting cylinder 45 are provided on the positioning platform mechanism 43. The lifting positioning assembly 44 and the limiting cylinder 45 are located behind the positioning platform mechanism 43.

[0040] The external plate-moving device places the plate onto the positioning platform mechanism 43. The lifting positioning component 44 and the limiting cylinder 45 are used to block and position the plate to be cut. After positioning, the lifting positioning component 44 and the limiting cylinder 45 retract below the positioning platform mechanism 43, releasing the positioning of the plate to be cut. After cutting, the finished product and the waste plate are connected by a micro-connection method, which is the plate to be processed. The external plate-moving device continues to move the plate to be processed and place it onto the plate placement platform 3. The external plate-moving device resets, and the pushing component 2 drives the plate placement platform 3 to move forward on the support frame component 1. The plate placement platform 3, together with the plate to be processed, passes through the material removal mechanism 4. After it is completely passed through, the plate placement platform 3, together with the plate to be processed, moves to the upper end of the transport and placement platform 5.

[0044] The telescopic end of the pusher cylinder 16 extends to drive the connecting piece 15 to move, thereby driving the plate placement platform 3 to move at the upper end of the support frame assembly 1. The pusher base 19 is used to install and fix the pusher assembly 2.

[0045] The board placement platform 3 includes a platform frame 28. Several first platform brushed boards 20 are laid flat on the upper rear side of the platform frame 28, and several second platform brushed boards 21 are laid flat on the upper front side of the platform frame 28. The positions and numbers of the first and second platform brushed boards 20 and 21 correspond, with the first platform brushed boards 20 abutting against the rear side of the corresponding second platform brushed boards 21. Several universal ball bearings 22 are provided at the upper ends of both the first and second platform brushed boards 20 and 21. Surrounding panels 23 are fixed around the platform frame 28, with the front surrounding panel 23... Several sets of side seats 24 are fixedly arranged evenly on the left and right sides. There are two side seats 24 in each set. Each side seat 24 is fixed with a discharge bearing seat 25. A discharge brush roller 26 is provided between the two discharge bearing seats 25 in each set.

The support wheel 42 abuts against the upper end of the side crossbeam 17 on the right side to facilitate stable movement. Each set of two unloading bearing seats 25 is provided with an unloading brush roller 26 for rolling to assist the plate in falling and unloading. The connecting seat 27 is fixedly connected to the upper end of the connecting piece 15 to apply force, which is used by the pushing assembly 2 to drive the plate placement platform 3 to move on the upper end of the support frame assembly 1.

[0047] The material feeding mechanism 4 includes a feeding frame 32, which is fixed in the middle of two side beams 17. Several mounting top plates 35 and two connecting top seats 38 are fixed to the upper rear side of the feeding frame 32. A lifting cylinder 36 is fixed to the lower end of each connecting top seat 38. A connecting plate 30 is fixed to the lower end of the telescopic end of each lifting cylinder 36. A toothed feeding plate 37 is fixed to the lower end of each connecting plate 30. A locking plate 31 is provided between the two toothed feeding plates 37.

The position and number of the lifting slide shafts 33 correspond to the linear bearings 34. The lifting slide shafts 33 are slidably arranged inside the corresponding linear bearings 34.

[0048] The pushing component 2 drives the plate placement platform 3 to move backward at the upper end of the support frame component 1. The plate placement platform 3, together with the plate to be cut, passes forward through the material removal mechanism 4. After it is fully passed through, the plate placement platform 3, together with the plate to be cut, moves to the upper end of the transport and placement platform 5. The telescopic end of the lifting cylinder 36 extends, driving the connecting plate 30 to move downward, that is, driving the two toothed material removal plates 37 to move downward. The locking plate 31 ensures that the two toothed material removal plates 37 move downward synchronously. The lifting slide shaft 33 is slidably set inside the linear bearing 34 at the corresponding position to ensure that the toothed material removal plates 37 descend stably. The toothed material removal plates 37 are placed behind the plate to be cut. The pushing component 2 drives the plate placement platform 3 to move backward at the upper end of the support frame component 1. The toothed material removal plates 37 push the plate to be cut off from the plate placement platform 3. After the push is completed, the telescopic end of the lifting cylinder 36 retracts.

[0049] The handling and placement platform 5 includes a placement bracket 39, with several placement boards 40 fixed to the upper end of the placement bracket 39, and solid wood pallets 41 movably placed on the several placement boards 40.

[0050] After the cut boards to be processed fall onto the solid wood pallet 41, the staff removes the solid wood pallet 41 from above several shelves 40 and then places an empty solid wood pallet 41.

[0051] The positioning platform mechanism 43 includes a positioning frame 46. Several third platform brush plates 47 are laid flat front and back on the upper end of the positioning frame 46. Several universal ball bearings 22 are provided on each of the third platform brush plates 47. Two clearance holes are opened on the last third platform brush plate 47. The lifting positioning component 44 and the limiting cylinder 45 are both set on the last third platform brush plate 47. The height of the third platform brush plate 47 is the same as the height of the first platform brush plate 20.

[0052] Several universal ball bearings 22 are used to support the plate and facilitate the plate to slide stably on the ball bearings 22. The lifting and positioning component 44 and the limiting cylinder 45 are both set on the platform brush plate 27 on the last side. They can extend from the two clearance holes to position the plate to be cut, ensuring stable and accurate cutting. After positioning, the lifting and positioning component 44 and the limiting cylinder 45 are retracted downward from the two clearance holes.

[0053] The telescopic end of the limiting cylinder 45 is located directly below one of the clearance holes; the lifting and positioning assembly 44 includes a lifting cylinder 48, the telescopic end of which is fixed to the lower end of the third platform brush plate 47 on the rearmost side. A mounting plate 53 is fixed on the lifting cylinder 48, and a proximity sensor 54 is fixed on the mounting plate 53. Two swing bearing seats 50 are fixed in the middle of the front side of the mounting plate 53, and a rotatable swing rod is provided between the two swing bearing seats 50. 49. The positioning rod 49 is provided with a sliding limit shaft 51 and a touch control rod 52 passing through it. The end of the sliding limit shaft 51 is connected to the mounting plate 53. A top spring is sleeved on the sliding limit shaft 51. The two ends of the top spring abut against the mounting plate 53 and the positioning rod 49 respectively. The touch control rod 52 is directly opposite the proximity sensor 54. An ejector rod is fixed at the upper end of the positioning rod 49. The ejector rod is located directly below another clearance hole and passes through the clearance hole.

[0054] The extension and retraction of the lifting cylinder 48 causes the main body of the lifting cylinder 48 to rise and fall in the opposite direction. The lifting cylinder 48 drives the mounting plate 53 to rise and fall, which in turn drives the proximity sensor 54, the two swing bearing seats 50, the sliding limit shaft 51, the touch control rod 52, the swing rod 49, and the ejector rod to rise and fall synchronously. This causes the swing rod 49 to rise and fall from the clearance hole, which in turn drives the ejector rod to rise and fall. The extension and retraction of the limit cylinder 45 extends from the clearance hole at the corresponding position, and the ejector rod rises and extends from the clearance hole at the corresponding position. After the plate abuts against the ejector rod, it pushes the swing rod 49. Rotating on the two swing bearing seats 50 causes the swing rod 49 to slide on the sliding limit shaft 51. The swing rod 49 presses against the top spring, and the swing rod 49 drives the touch control rod 52 to move. The touch control rod 52 abuts against the proximity sensor 54, controlling the device for placing the external board to stop pushing the board and completing the board positioning. After positioning, the lifting cylinder 48 and the limit cylinder 45 descend and retract, and the top spring drives the swing rod 49 to reset. At this time, the touch control rod 52 disengages from the proximity sensor 54, ensuring that the device for placing the external board will stop pushing the board next time.

[0055] The working principle of this utility model is as follows: The external plate-moving device places the plate onto the positioning platform mechanism 43. The lifting positioning component 44 and the limiting cylinder 45 are used to block and position the plate to be cut. Several universal ball bearings 22 are used to support the plate and facilitate stable sliding of the plate on the ball bearings 22. The lifting positioning component 44 and the limiting cylinder 45 are both set on the platform brush plate 27 on the last side and can extend from two clearance holes to position the plate to be cut, ensuring stable and accurate cutting. After positioning, the lifting positioning component 44 and the limiting cylinder 45 are retracted downward from the two clearance holes, releasing the positioning of the plate to be cut. That is, the telescopic end of the lifting cylinder 48 extends and retracts, thereby driving the main body of the lifting cylinder 48 to rise and fall in the opposite direction. The lifting cylinder 48 drives the mounting plate 53 to rise and fall, that is, it drives the proximity sensor 54, the two swing bearing seats 50, the sliding limiting shaft 51, and the touch control. The rod 52, the positioning rod 49, and the ejector rod rise and fall synchronously, causing the positioning rod 49 to rise and fall from the clearance hole, which in turn drives the ejector rod to rise and fall. The telescopic end of the limit cylinder 45 extends from the clearance hole at the corresponding position, and the ejector rod rises and extends from the clearance hole at the corresponding position. After the plate abuts against the ejector rod, it pushes the positioning rod 49 to rotate on the two positioning bearing seats 50, causing the positioning rod 49 to slide on the sliding limit shaft 51. The positioning rod 49 presses against the top spring, and the positioning rod 49 drives the touch control rod 52 to move. The touch control rod 52 abuts against the proximity sensor 54, controlling the device for placing the plate externally to stop pushing the plate, completing the plate positioning. After positioning, the lifting cylinder 48 and the limit cylinder 45 descend and retract, and the top spring drives the positioning rod 49 to reset. At this time, the touch control rod 52 disengages from the proximity sensor 54, ensuring that the device for placing the plate externally will stop pushing the plate next time.

[0056] After cutting, the finished product and the scrap board are connected by a micro-connection method to form the cut board to be processed.

[0057] The external plate-shifting device continues to move the plate to be cut onto the plate placement platform 3. Several universal ball bearings 22 are used to support the plate and facilitate stable sliding of the plate on the ball bearings 22. The external plate-shifting device then resets.

[0058] The extension end of the push cylinder 16 extends and drives the connecting piece 15 to move, thereby driving the plate placement platform 3 to move on the upper end of the support frame assembly 1. That is, the guide roller 29 is engaged with the upper end of the tapered guide rail 12 to guide the plate placement platform 3. The support wheel 42 abuts against the upper end of the side beam 17 on the right side to facilitate stable movement.

[0059] After the board placement platform 3 and the board to be cut pass through the material feeding and removal mechanism 4 and are completely pierced, the board placement platform 3 and the board to be cut move to the upper end of the transport and placement platform 5.

[0060] The extension end of the lifting cylinder 36 extends, causing the connecting plate 30 to move downward, which in turn causes the two toothed material-pulling plates 37 to move downward. The locking plate 31 ensures that the two toothed material-pulling plates 37 move downward synchronously. The lifting slide shaft 33 is slidably set inside the linear bearing 34 at the corresponding position to ensure that the toothed material-pulling plates 37 descend stably. The toothed material-pulling plates 37 are placed on the rear side of the plate to be cut. The pushing component 2 drives the plate placement platform 3 to move backward at the upper end of the support frame component 1. The toothed material-pulling plates 37 push the plate to be cut from the plate placement platform 3. The plate to be cut rolls along the unloading brush roller 26 to assist in falling and unloading.

[0061] After the cut boards to be processed fall onto the solid wood pallet 41, the staff removes the solid wood pallet 41 from above several shelves 40 and then places an empty solid wood pallet 41.

[0062] In summary, by cooperating with the support frame assembly 1 and the board placement platform 3, the board placement platform 3 can move back and forth on the support frame assembly 1, which facilitates quick unloading.

[0063] By cooperating with the pusher assembly 2 and the board placement platform 3, the pusher assembly 2 drives the board placement platform 3 to move for unloading.

[0064] By cooperating with the material removal mechanism 4 and the board placement platform 3, the cutting board to be processed can be quickly transferred to the upper end of the handling and holding platform 5. The unloading is stable and convenient, and the handling and holding platform 5 facilitates rapid material discharge.

[0065] By cooperating with the plate placement platform 3 and the positioning platform mechanism 43, the plate can be transferred quickly and stably.

[0066] The plate placement platform 3 works in conjunction with the lifting and positioning component 44 and the limiting cylinder 45 to stably and quickly position the plate to be cut, ensuring accurate cutting and accurate transfer to the plate placement platform 3.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
