Description

Technical Field

[0001] The present invention relates to the technical field of laser processing equipment, and more specifically to a laser cutting equipment for producing a combined display rack. Background Art

[0002] Laser cutting can be divided into two categories: tubular metal cutting and sheet metal cutting. When cutting sheet metal, it is placed on a conical block for laser cutting.

[0003] At present, most of the laser cutting equipment used in the production of modular display racks manually places the display rack on several conical blocks and fixes the display rack by the conical blocks.

DETAILED DESCRIPTION

[0037] Embodiment 1:

[0038] See also Figure 1 , a laser cutting device for producing a combined display stand, comprising a bottom plate 2, a side plate 1 is fixedly connected to one side of the bottom plate 2, a moving component 5 is fixedly connected to one end of the side plate 1 away from the bottom plate 2, a laser cutting component 3 is arranged on the side of the moving component 5 close to the bottom plate 2, a supporting component 4 is arranged at the center of the bottom plate 2, a pushing component 6 is arranged on one side of the supporting component 4, the pushing component 6 is connected to the bottom plate 2, and a positioning component 7 is arranged inside the side plate 1;

[0039] See also Figure 2 and Figure 3 The moving component 5 includes a protection box 503 fixedly connected to the side plate 1, and a partition plate 502 is fixedly connected inside the protection box 503. A motor 2 501 is arranged on one side of the partition plate 502. There are two motors 2 501. A worm 506 is arranged on the side of the partition plate 502 away from the motor 2 501. There are two worms 506 and the worm 506 passes through the partition plate 502. The worms 506 are respectively fixedly connected to the output ends of the motor 2 501. A limiting rod 505 is arranged on the end of the worm 506 close to the bottom plate 2. The limiting rod 505 is fixedly connected to the partition plate 502 and the protection box 503.

[0040] See also Figure 3 and Figure 4 A turbine 507 is meshed between the worm gear 506, and a connecting column 508 is fixedly connected to one end of the turbine 507 close to the base plate 2. A moving block 509 is arranged on the outer side of the connecting column 508. The moving block 509 is slidably connected to the limiting rod 505. The connecting column 508 passes through the moving block 509. A gear 510 is fixedly connected to one end of the connecting column 508 away from the turbine 507, and the gear 510 is slidably connected to the moving block 509.

[0041] Specifically, when the display rack is positioned, the staff starts the motor 2 501. The rotation of the motor 2 501 will drive the corresponding worm 506 to rotate. When the two worms 506 turn in opposite directions, the turbine 507 only rotates but does not move. At this time, the path of the connecting plate 1 504 moving left and right can be controlled according to the rotation of the turbine 507. When the two worms 506 rotate in the same direction, the turbine 507 only moves but does not rotate. At this time, the connecting plate 1 504 can be controlled to move forward and backward, thereby driving the connecting plate 1 504 to move, so that the laser cutting component 3 can move within a larger range.

[0042] See also Figure 5 The upper end of the moving block 509 is fixedly connected to a fixed block 511, and the fixed block 511 is slidably connected to a limiting rod 512, and the outer side of the limiting rod 512 is fixedly connected to a connecting plate 504. A rack 513 is meshed with the outer side of the gear 510, and the rack 513 is located on the side of the gear 510 away from the fixed block 511. A moving groove 514 is slidably connected to the outer side of the rack 513. The moving groove 514 is fixedly connected to the moving block 509, and the rack 513 is fixedly connected to the connecting plate 504. The end of the connecting plate 504 away from the worm 506 is connected to the laser cutting component 3.

[0043] Specifically, when the gear 510 rotates, it will drive the rack 513 to move. When the rack 513 moves on the moving groove 514, it will drive the connecting plate 504 to move synchronously. At the same time, the limit rod 512 imposes a certain displacement restriction on the movement of the connecting plate 504, so that the movement of the connecting plate 504 is more stable. The movement of the connecting plate 504 then drives the laser cutting component 3 to move synchronously, so that the laser cutting component 3 can follow the connecting plate 504 to move to a larger range for laser welding, thereby reducing the space occupied by the equipment and completing the corresponding cutting work.

[0044] See also Figure 6 and Figure 8The laser cutting component 3 includes a connecting plate 301 fixedly connected to the moving component 5, a disk 311 is arranged at the center of the connecting plate 301, a central gear 313 is rotatably connected to the center of the disk 311, and the central gear 313 is fixedly connected to the connecting block 302 at one end away from the connecting plate 301, a gear ring is arranged on the inner side of the disk 311, and a plurality of small gears 314 are meshed on the inner side of the gear ring, and the small gears 314 are all meshed with the central gear 313, and a motor 312 is fixedly installed at one end of the disk 311 away from the connecting block 302, and the output end of the motor 312 passes through the disk 311 and is fixedly connected to the central gear 313.

[0045] Specifically, when the laser cutting head 306 needs to turn during cutting, the motor 312 can control the center gear 313 to rotate. The rotation of the center gear 313 will drive the connecting block 302 to rotate synchronously, thereby enabling the laser cutting head 306 to rotate synchronously. In conjunction with the moving component 5 to control the movement of the laser cutting head 306, the laser cutting head 306 can complete more complex cutting tasks. At the same time, the rotation of the center gear 313 will drive the small gear 314 to rotate synchronously, making the rotation of the connecting block 302 more stable and controllable, thereby facilitating the realization of high-precision cutting tasks.

[0046] See also Figure 6 and Figure 7 One end of the connecting block 302 away from the connecting plate 301 is fixedly connected to several electric telescopic rods 303, one end of the electric telescopic rods 303 away from the connecting block 302 is fixedly connected to a laser control box 307, one end of the laser control box 307 away from the connecting plate 301 is fixedly connected to a clamping plate 315, and an electric telescopic frame 305 is arranged at the center of the clamping plate 315, the electric telescopic frame 305 is fixedly connected to the laser control box 307, and a laser cutting head 306 is fixedly connected to the center of the electric telescopic frame 305.

[0047] See also Figure 6 and Figure 7 , an oxygen storage box 308 is fixedly connected to one side of the electric telescopic frame 305, and a storage box 304 is fixedly connected to one end of the electric telescopic frame 305 away from the oxygen storage box 308, an injection head 309 is connected between the electric telescopic frame 305 and the oxygen storage box 308, and a suction port 310 is connected between the electric telescopic frame 305 and the storage box 304. Infrared transmitters and receivers are arranged on both sides of the clamping plate 315 perpendicular to the injection head 309. By arranging the infrared transmitter and receiver, the electric telescopic frame 305 can drive the laser cutting head 306 to move accurately to the focal position, so that the equipment can be suitable for display racks of different thicknesses, and the clamping plate 315 can also intercept the waste generated during cutting to a certain extent, and the suction force of the suction port 310 can effectively remove the waste generated during cutting, thereby reducing the subsequent cleaning process.

[0048] Specifically, before starting cutting, the laser control box 307 is controlled to descend by the electric telescopic rod 303 until the clamping plate 315 contacts the display frame. When the clamping plate 315 contacts the display frame, the clamping effect of the clamping plate 315 and the support assembly 4 on the display frame makes it difficult for the display frame to deform during cutting. After the clamping plate 315 contacts the display frame, the electric telescopic frame 305 drives the laser cutting head 306 to start descending, and the infrared transmitter and receiver inside the electric telescopic frame 305 can accurately control the laser. The optical cutting head 306 moves to the focal position. When the laser cutting head 306 moves to the focal position, the equipment can start cutting. During the cutting process, the nozzle 309 will spray out the oxygen stored in the oxygen storage box 308, which can improve the cutting efficiency and blow the debris generated by the cutting to the suction port 310. The suction port 310 will adsorb the inside of the clamping plate 315, take away the heat and adsorb the debris generated during cutting into the storage box 304 for collection, which is convenient for subsequent centralized processing.

[0049] See also Fig. 9 The positioning assembly 7 includes a fixed block 704 fixedly connected to the side plate 1, and the fixed block 704 is internally rotatably connected to a bidirectional threaded rod 702, the bidirectional threaded rod 702 is rotatably connected to the side plate 1, one side of the bidirectional threaded rod 702 is connected to a motor, and the motor is located inside the side plate 1, and the bidirectional threaded rod 702 is threadedly connected to a moving block 2 703, there are two moving blocks 2 703 and they are symmetrically distributed with the fixed block 1 704 as the symmetry axis, and each moving block 2 703 is fixedly connected to a pushing block 701 at one end close to the supporting assembly 4.

[0050] Specifically, when the pushing component 6 pushes the display rack to contact the fixed block 1 704, the motor will start synchronously. After the motor starts, it will control the bidirectional threaded rod 702 to rotate, so that the two moving blocks 2 703 move toward each other. The movement of the moving block 2 703 will drive the pushing block 701 to move synchronously. Through the pushing effect of the pushing block 701 on the display rack, the display rack can be accurately located at the center of the equipment, and during the cutting process, the pushing block 701 still maintains a certain clamping effect on the display cabinet to prevent the display cabinet from being displaced during the cutting process.

[0051] See also Fig.10 and Fig.11The pushing component 6 includes an isolation plate 605 fixedly connected to the bottom plate 2, and a motor three 604 is fixedly mounted on one side of the isolation plate 605 close to the side plate 1, and a gear one 606 is fixedly connected to the output end of the motor three 604, and the gear one 606 is rotatably connected to the isolation plate 605. A chain 608 is transmission-connected to the outer side of the gear one 606, and a gear two 607 is transmission-connected to the side of the chain 608 away from the gear one 606. There are two gear two 607 and they are symmetrically distributed with the gear one 606 as the symmetry axis, and each gear two 607 is fixedly connected to a threaded rod 603 at one end away from the motor three 604, and a moving block one 602 is threadedly connected to the threaded rod 603, and a pushing plate 601 is fixedly connected between the moving blocks one 602.

[0052] Specifically, when the staff places the display rack on the support assembly 4, the motor three 604 is started. The start of the motor three 604 will drive the gear one 606 to rotate. The rotation of the gear one 606 will drive the gear two 607 to rotate through the chain 608. The rotation of the gear two 607 will drive the threaded rod 603 to rotate synchronously. The rotation of the threaded rod 603 will enable the moving block one 602 to move, and then drive the pushing plate 601 to move, so as to push the display cabinet so that one end of the display cabinet contacts the side panel 1.

[0053] See also Fig.12 and Fig.13 The supporting assembly 4 includes a bottom plate 403 fixedly connected to the bottom plate 2, a plurality of conical blocks 402 are fixedly connected to the upper end of the bottom plate 403, a plurality of threaded rods 404 are rotatably connected to one end of the bottom plate 403 close to the moving assembly 5, the upper thread of the threaded rod 404 is threadedly connected to the supporting plate 401, a plurality of openings are provided on the supporting plate 401, and the openings correspond to the positions of the conical blocks 402, a gear three 406 is fixedly connected to one end of each threaded rod 404 away from the moving assembly 5, the gear three 406 is rotatably connected to the bottom plate 403, a chain 407 is transmission-connected to the outer side of the gear three 406, a bevel gear 405 is rotatably connected to one end of the bottom plate 403 away from the moving assembly 5, the bevel gear 405 is transmission-connected to the chain 407, and the end of the bevel gear 405 away from the chain 407 is meshed with the gear one 606.

[0054] See also Fig.14 , Fig.15 and Fig.16A plurality of limit assemblies 413 are provided on the support plate 401. The limit assemblies 413 include rotating teeth 409 threadedly connected to the threaded rod 404. The outer side of the rotating teeth 409 is meshed with meshing teeth 408. Both sides of the meshing teeth 408 are fixedly connected with connecting rods 411. One end of the connecting rod 411 away from the meshing teeth 408 is fixedly connected with a pressing block 410. The pressing blocks 410 are respectively located on both sides of the support plate 401. A spring 412 is provided on the outer side of the connecting rod 411. The spring 412 is respectively fixedly connected to the pressing block 410 and the meshing teeth 408.

[0055] Specifically, when gear 1 606 drives bevel gear 405 to rotate, bevel gear 405 drives gear 3 406 to rotate through chain 1 407, thereby causing threaded rod 1 404 to rotate. After threaded rod 1 404 rotates, it drives rotating gear 409 to rotate. At this time, since meshing teeth 408 are meshed with rotating teeth 409, rotating teeth 409 cannot rotate, thereby enabling support plate 401 to move on threaded rod 1 404. When support plate 401 moves to contact with bottom plate 2, bottom plate 2 presses pressing block 410 above support plate 401, so that meshing teeth 408 move and do not mesh with rotating teeth 409. At this time, rotating teeth 409 can rotate freely, thereby enabling support plate 401 and bottom plate 2 to move. After contacting, they stay still, and the pushing component 6 can operate normally, so that when the pushing component 6 pushes the display rack, the display rack can be located on the surface of the support plate 401. When the pushing component 6 starts to retreat, under the action of gravity, the rotating tooth 409 will be subject to a part of the rotation resistance, so that the rotating tooth 409 will not rotate, and the support plate 401 will be driven to move downward. When the support plate 401 moves downward, the pressing block 410 will be reset under the action of the spring 1 412, thereby controlling the meshing tooth 408 to mesh with the rotating tooth 409, limiting the rotation of the rotating tooth 409, and when the support plate 401 drops to contact with the bottom plate 1 403, the bottom plate 1 403 will squeeze the pressing block 410 under the support plate 401, so that the rotating tooth 409 can continue to rotate.

[0056] Working principle of the present invention: when the staff puts the display rack on the support assembly 4, the motor three 604 is started. The motor three 604 starts to drive the gear one 606 to rotate. The rotation of the gear one 606 drives the gear two 607 to rotate through the chain 608. When the gear two 607 rotates, it drives the threaded rod 603 to rotate synchronously. The rotation of the threaded rod 603 enables the moving block one 602 to move, and then drives the push plate 601 to move, pushing the display cabinet so that one end of the display cabinet contacts the side plate 1. When the push assembly 6 pushes the display rack to contact the fixed block one 704, the motor will start synchronously. After the motor starts, it will control the bidirectional threaded rod 702 to move. The two moving blocks 703 rotate to move toward each other. The movement of the moving block 703 drives the push block 701 to move synchronously. The push block 701 drives the display rack so that the display rack can be accurately located at the center of the equipment. In the cutting process, the push block 701 still maintains a certain clamping effect on the display cabinet to prevent the display cabinet from shifting during the cutting process. When the display cabinet is positioned, the staff starts the motor 501. The rotation of the motor 501 drives the corresponding worm 506 to rotate. When the two worms 506 rotate in opposite directions, the turbine 507 only rotates but does not move. At this time, the connection plate 1 504 can be controlled to move left and right according to the rotation of the turbine 507. The moving path, and when the two worm gears 506 rotate in the same direction, the turbine 507 only moves but does not rotate. At this time, the connecting plate 504 can be controlled to move forward and backward, thereby driving the connecting plate 504 to move, so that the laser cutting component 3 can move within a larger range. When the laser cutting component 3 moves to the specified position, the laser control box 307 is controlled to descend by the electric telescopic rod 303 until the clamping plate 315 contacts the display rack. When the clamping plate 315 contacts the display rack, the clamping effect of the clamping plate 315 and the support assembly 4 on the display rack makes it difficult for the display rack to deform during cutting. When the clamping plate 315 contacts the display rack, the electric The telescopic frame 305 drives the laser cutting head 306 to begin to descend. The infrared transmitter and receiver on the inside of the electric telescopic frame 305 can accurately control the laser cutting head 306 to move to the focal position. When the laser cutting head 306 moves to the focal position, the equipment can start cutting. During the cutting process, the jet head 309 will spray out the oxygen stored in the oxygen storage box 308, which can improve the cutting efficiency and blow the debris generated by the cutting to the suction port 310. The suction port 310 will adsorb the inside of the clamping plate 315, taking away the heat and adsorbing the debris generated during cutting into the storage box 304 for collection, which is convenient for subsequent centralized processing.
