[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt and vaporize to its ignition point. Simultaneously, a high-speed gas stream coaxial with the laser beam blows away the molten material, thus cutting the workpiece. Laser cutting is a type of thermal cutting method. It involves using a high-power-density laser beam to irradiate the material being cut, quickly heating it to its vaporization temperature to complete the cutting process.

[0003] The invention with patent CN113857659A relates to a laser cutting device, which includes a worktable, a rotary conveying assembly, a laser cutting assembly, a guiding assembly, and a cleaning assembly; the rotation of the rotary conveying assembly pushes the cleaning assembly to slide along the extension direction of the conveying surface to clean the material on the conveying surface; it solves the problem that impurities on the material surface can easily affect the laser cutting process, and that the material surface is not easy to clean after laser cutting.

[0004] In the production of metal sheets, laser cutting machines are used to cut suitable parts. Although the laser cutting equipment in the aforementioned patent is convenient for cleaning debris from the material surface, the metal sheets are heavy, making the sheet handling difficult, and the fumes generated during cutting and burning spread everywhere, easily causing air pollution. Therefore, we provide a robotic arm auxiliary device for laser cutting to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a robotic arm-assisted device for laser cutting in order to solve the problems mentioned above, such as the difficulty in handling the sheet metal and the easy generation of smoke and dust during burning.

The positioning mechanism includes a material carrying platform, a lifting plate, and a power conveying shaft. A plate support seat is fixedly connected to the surface of the material carrying platform. The surface of the lifting plate is provided with equidistantly arranged transport mechanisms. The transport mechanisms include a fixed frame and a conveyor belt, and the fixed frame is fixedly connected to the lifting plate.

[0008] Preferably, a laser emitting end is fixedly connected to the end of the robotic arm, and an absorption ring is fixed to the bottom of the laser emitting end. The bottom of the absorption ring has circumferentially arranged through holes. A fixing frame is snapped into the middle of the purification box, and a filter adsorption block is fixedly connected inside the fixing frame. A power fan is fixedly connected to the top of the purification box. By positioning the absorption ring, the absorption ring is made to fit tightly against the outer ring of the laser cutting position, so as to perform all-round absorption of the laser cutting position, avoid impurities from spreading in all directions, and improve the absorption effect of the absorption ring on waste gas and impurities.

[0009] Preferably, a mounting plate is fixedly connected to the surface of the purification box, and two sets of fixing semi-rings abut against each other on the surface of the robotic arm. Each fixing semi-ring is fixedly connected to a fixing bolt, and each fixing bolt is assembled and connected to the adjacent mounting plate. By fixing bolts, the fixing semi-rings are fixedly connected to the mounting plate, thereby fixing the purification box to the surface of the robotic arm and improving the convenience of purification box installation.

[0010] Preferably, a fixing ring is fitted on the surface of the connecting tube, and a spring telescopic rod is fixedly connected to the surface of the fixing ring. The fixed end of the spring telescopic rod is fixedly connected to an adjacent fixing half-ring. The two ends of the connecting tube are fixedly connected to the purification box and the suction ring, respectively.

The other end of each connecting crossbar is fixedly connected to a triangular slider. The bottom of each triangular slider is rotatably connected to two sets of side support wheels, and each side support wheel is rollingly connected to the equipment body. The support slide rods support and position the connecting crossbars, preventing the position adjustment block from rotating when the threaded rod rotates, thus improving the stability of the lateral movement of the threaded rod.

[0014] Preferably, each of the triangular sliders is fixedly connected to a positioning block on its surface, and each of the four corners of the lifting plate is fixedly connected to an inclined slider. Each inclined slider is slidably connected to an adjacent triangular slider.

[0016] Preferably, a support shaft is rotatably connected to the top of the fixed frame, and the support shaft is connected to the conveyor belt for transmission.

The power transmission shaft controls the rotation of the power wheel, so that the power wheel drives the conveyor belt for transmission, and the plate is transported through the conveyor belt.

[0017] This invention provides a robotic arm-assisted device for laser cutting, which has the following beneficial effects: 1. This robotic arm auxiliary device for laser cutting uses a fixed assembly of the robotic arm within the main body of the equipment. The robotic arm moves the laser emitter to cut metal sheets, improving the stability and accuracy of the cutting process. A suction ring collects the debris and fumes generated by the laser ablation, preventing the fumes from spreading and causing air pollution, thus improving the environmental performance of laser cutting. A connecting pipe transports the waste gas collected by the suction ring to a purification chamber for purification and filtration. The system filters and intercepts debris and particulate matter within the waste gas, improving air purification efficiency. The device also includes a material loading mechanism. The platform supports and fixes the sheet metal support base, which in turn supports and positions the sheet metal to prevent displacement during cutting and improve the accuracy of the cutting process. The lifting plate moves up and down, driving the transport mechanism. When loading is required, the lifting plate moves the fixed frame, ensuring that the height of the conveyor belt is above the sheet metal support base. The conveyor belt then transports the sheet metal, allowing the finished sheet metal to be delivered directly above the platform or removed from the platform, thus improving the efficiency of laser cutting of sheet metal.

[0018] 2. This robotic arm-assisted device for laser cutting positions the suction ring, ensuring it fits snugly against the outer ring of the laser cutting area. This allows for omnidirectional suction of the laser-cut area, preventing impurities from spreading and improving the suction ring's effectiveness in removing waste gas and impurities. A fixed frame positions the filter adsorption block, which then filters and adsorbs the waste gas. The fixed frame is connected via a snap-fit ​​mechanism, facilitating easy replacement of the filter adsorption block after a specified period of use, thus improving device maintenance efficiency. A power fan creates negative pressure inside the purification chamber, further enhancing the suction ring's ability to adsorb nearby gases. Air is drawn in, and the fixing half-ring is fixedly connected to the mounting plate by fixing bolts, thereby fixing the purification box to the surface of the robotic arm, improving the convenience of purification box installation. When the laser emitting end drives the suction ring to move, the spring telescopic rod and the fixing ring provide buffer for the connecting pipe, so that the connecting pipe is in close contact with the surface of the robotic arm, preventing the connecting pipe from shaking randomly, reducing the interference of the connecting pipe on the operation of the equipment, and improving the stability of the equipment operation. The support legs provide support and fixation for the material carrying platform, and the positioning slip ring and the support legs position the lifting plate, improving the stability of the lifting plate sliding up and down.

[0019] 3. This robotic arm auxiliary device for laser cutting protects the equipment at the bottom of the material handling platform through a protective shell, improving the stability of equipment operation. The first motor controls the rotation of the threaded rod, which, after rotating inside the position adjustment block, causes the block to move laterally. A support slide rod supports and positions the connecting crossbar, preventing the position adjustment block from rotating along with the threaded rod, thus improving the stability of the threaded rod's lateral movement. It also supports the triangular slider, improving its sliding stability. The lateral movement of the triangular slider compresses the tilting slider, causing the tilting slider to move the lifting plate up and down. Positioning blocks and limit slides further enhance the stability of the device. The groove positions the inclined slider and triangular slider to prevent misalignment and improve the stability of the inclined slider's up-and-down sliding motion. A second motor controls the rotation of the power worm gear, which in turn controls the rotation of the transmission worm wheel, which in turn controls the synchronous rotation of the power conveyor shaft. The meshing transmission between the power worm gear and the transmission worm wheel increases the power output torque, making the conveyor belt transport of metal sheets more stable. A support shaft supports the conveyor belt, further improving its stability. The power conveyor shaft controls the rotation of the power wheel, which drives the conveyor belt to transport the metal sheets. Attached Figure Description

[0022] This invention provides a robotic arm-assisted device for laser cutting.

[0023] Please see Figure 1 and Figure 2 The device includes a main body 1, a robotic arm 2 mounted on the top of the main body 1, and a laser emitter 201 fixedly connected to the end of the robotic arm 2. The robotic arm 2 is fixedly mounted on the main body 1, and the robotic arm 2 drives the laser emitter 201 to move, thereby cutting metal plates and improving the stability and accuracy of plate cutting.

[0024] Please refer to it again. Figure 2 , Figure 3 , Figure 4 and Figure 5 The robotic arm 2 is equipped with a purification mechanism 3 on its exterior. The purification mechanism 3 includes a purification box 301, a connecting pipe 302, and a suction ring 303. The suction ring 303 is used to absorb the debris and fumes generated by laser ablation, preventing the fumes from spreading and causing air pollution in the vicinity, thus improving the environmental performance of laser cutting. The exhaust gas absorbed by the suction ring 303 is transported to the purification box 301 through the connecting pipe 302 for purification and filtration. The exhaust gas is filtered and intercepted to improve the air purification effect.

[0025] The suction ring 303 is fixed to the bottom of the laser emitting end 201. The bottom of the suction ring 303 has circumferentially arranged through holes. A fixing frame 305 is snapped into the middle of the purification box 301. A filter adsorption block 306 is fixedly connected inside the fixing frame 305. A power fan 304 is fixedly connected to the top of the purification box 301. The power fan 304 is a mature device. This application can use existing equipment that can draw air from inside the purification box 301. By positioning the suction ring 303, the suction ring 303 is made to fit tightly against the outer ring of the laser cutting position, so as to draw air from all directions in the laser cutting position, avoid impurities from spreading in all directions, and improve the suction effect of the suction ring 303 on waste gas and impurities. The filter adsorption block 306 is positioned by the fixing frame 305.

[0026] The filter adsorption block 306 is a mature air purification material. This application can use existing materials for air purification and filtration. The filter adsorption block 306 is used to filter and adsorb exhaust gas. The fixing frame 305 is connected by a snap-fit ​​method. After the filter adsorption block 306 has been used for a specified period of time, it is convenient to replace it with a new filter adsorption block 306, which improves the maintenance efficiency of the device. The power fan 304 creates negative pressure inside the purification box 301, which causes the suction ring 303 to draw in the surrounding air.

[0027] A mounting plate 308 is fixedly connected to the surface of the purification box 301. Two sets of fixing semi-rings 307 are mutually abutting on the surface of the robotic arm 2. Each fixing semi-ring 307 is fixedly connected to a fixing bolt 309, and each fixing bolt 309 is assembled and connected to the mounting plate 308. The fixing semi-rings 307 and the mounting plate 308 are fixedly connected together by the fixing bolts 309, thereby fixing the purification box 301 to the surface of the robotic arm 2 and improving the convenience of installing the purification box 301.

[0028] A fixing ring 310 is fitted on the surface of the connecting pipe 302. A spring telescopic rod 311 is fixedly connected to the surface of the fixing ring 310, and the fixed end of the spring telescopic rod 311 is fixedly connected to the adjacent fixing half ring 307. The two ends of the connecting pipe 302 are fixedly connected to the purification box 301 and the suction ring 303, respectively. When the laser emitting end 201 drives the suction ring 303 to move, the spring telescopic rod 311 and the fixing ring 310 provide a buffer for the connecting pipe 302, so that the connecting pipe 302 is tightly attached to the surface of the robotic arm 2, preventing the connecting pipe 302 from shaking randomly, reducing the interference of the connecting pipe 302 on the operation of the equipment, and improving the stability of the equipment operation.

[0029] Please see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The bottom of the equipment body 1 is provided with a positioning mechanism 4. The positioning mechanism 4 includes a material carrying platform 401, a lifting plate 405 and a power conveying shaft 417. A plate support seat 402 is fixedly connected to the surface of the material carrying platform 401. The material carrying platform 401 supports and fixes the plate support seat 402, and the plate support seat 402 supports and positions the metal plate, so as to avoid displacement of the metal plate during cutting and improve the accuracy of metal plate cutting.

[0030] A positioning slip ring 406 is fixedly connected to the surface of the lifting plate 405. A support leg 404 is slidably connected inside the positioning slip ring 406. The two ends of the support leg 404 are fixedly connected to the equipment body 1 and the material platform 401, respectively. A protective shell 403 is fixedly connected to the surface of the material platform 401. The bottom of the protective shell 403 is fixedly connected to the equipment body 1. The support leg 404 provides support and fixation for the material platform 401. The positioning slip ring 406 and the support leg 404 position the lifting plate 405, improving the stability of the lifting plate 405 sliding up and down. The protective shell 403 protects the equipment at the bottom of the material platform 401, improving the stability of the equipment operation.

[0031] A first motor 416 is fixedly connected to the surface of the device body 1. The first motor 416 is a mature device. This application can use existing devices that can control the rotation of the threaded rod 415. The two output ends of the first motor 416 are fixedly connected to the threaded rod 415. The surface of each threaded rod 415 is threadedly connected to a position adjustment block 414. The surface of each position adjustment block 414 is fixedly connected to a connecting crossbar 412. The first motor 416 controls the rotation of the threaded rod 415. After the threaded rod 415 rotates inside the position adjustment block 414, the position adjustment block 414 moves laterally.

[0032] Each connecting crossbar 412 has a supporting slide bar 413 slidably connected to its middle section, and each supporting slide bar 413 is fixedly connected to the equipment body 1. The other end of each connecting crossbar 412 is fixedly connected to a triangular slider 409. The bottom of each triangular slider 409 is rotatably connected to two sets of side support wheels 411, and each side support wheel 411 is rollingly connected to the equipment body 1. The supporting slide bar 413 supports and positions the connecting crossbar 412, preventing the position adjusting block 414 from rotating when the threaded rod 415 rotates, thus improving the stability of the lateral movement of the threaded rod 415. It also supports the triangular slider 409, improving the sliding stability of the triangular slider 409.

[0033] Each triangular slider 409 has a positioning block 410 fixedly connected to its surface, and each of the four corners of the lifting plate 405 has an inclined slider 407 fixedly connected to its corner. Each inclined slider 407 is slidably connected to the adjacent triangular slider 409. Each inclined slider 407 has a limiting groove 408 in its middle, and each positioning block 410 is slidably connected to the limiting groove 408. By moving the triangular slider 409 laterally to press the inclined slider 407, the inclined slider 407 drives the lifting plate 405 to move up and down. The positioning block 410 and the limiting groove 408 are used to position the inclined slider 407 and the triangular slider 409 to prevent displacement and improve the stability of the triangular slider 409 pressing the inclined slider 407 to slide up and down.

[0034] A transmission worm gear 418 is fixedly connected to the middle of the power conveying shaft 417. The transmission worm gear 418 is meshed with a power worm 419. A second motor 421 that controls the rotation of the power worm 419 is fixedly connected to the surface of the lifting plate 405. The second motor 421 is a mature device, and this application can use existing equipment that can control the rotation of the power worm 419. A fixed housing 420 is fixedly connected to the surface of the lifting plate 405, and the fixed housing 420 is sleeved outside the transmission worm gear 418 and the power worm 419. The second motor 421 controls the rotation of the power worm 419, and the power worm 419 controls the rotation of the transmission worm gear 418, so that the transmission worm gear 418 controls the synchronous rotation of the power conveying shaft 417. Through the meshing transmission of the power worm 419 and the transmission worm gear 418, the power output torque can be increased, making the conveyor belt 502 transport metal plates more stably.

[0035] Please see Figure 11 The surface of the lifting plate 405 is provided with equidistantly arranged transport mechanisms 5. The transport mechanism 5 includes a fixed frame 501 and a conveyor belt 502. The fixed frame 501 is fixedly connected to the lifting plate 405. The transport mechanism 5 moves by the up and down movement of the lifting plate 405. When material needs to be loaded, the fixed frame 501 is moved by the lifting plate 405, so that the height of the conveyor belt 502 is above the plate support seat 402. The metal plate is transported by the conveyor belt 502. The finished metal plate can be transported to the material platform 401, and the cut metal plate can be transported out of the material platform 401, thereby improving the efficiency of laser cutting of metal plates.

[0036] A support shaft 504 is rotatably connected to the top of the fixed frame 501, and the support shaft 504 is driven by the conveyor belt 502. Power wheels 503 are rotatably connected to both ends of the fixed frame 501, and the power wheels 503 are driven by the conveyor belt 502. The power conveying shaft 417 is fixedly connected to the adjacent power wheel 503. The support shaft 504 supports the conveyor belt 502, improving the stability of the conveyor belt 502 in conveying metal sheets. The power conveying shaft 417 controls the rotation of the power wheel 503, so that the power wheel 503 drives the conveyor belt 502 to drive the sheet metal through the conveyor belt 502.

[0037] The drive wheel 503 and the conveyor belt 502 are driven by surface friction or the teeth on the surface of the drive wheel 503. The transmission relationship between them can refer to the connection method of existing conveyor equipment, which will not be described in detail in this application. The power fan 304, the first motor 416 and the second motor 421 are all electrically connected to the controller inside the equipment body 1. The controller can operate and control the power fan 304, the first motor 416 and the second motor 421. The electrical signal connection is an essential technology for equipment maintenance and installation, which will not be described in detail in this application.

[0038] Working principle: When material needs to be loaded, the first motor 416 controls the rotation of the threaded rod 415. The threaded rod 415 rotates inside the position adjusting block 414, which in turn drives the connecting crossbar 412 and the triangular slider 409 to move laterally. The lateral movement of the triangular slider 409 presses against the inclined slider 407, causing the inclined slider 407 to move the lifting plate 405 upwards, lifting the conveyor belt 502 to the top of the material platform 401. Then, the second motor 421 controls the rotation of the power worm gear 419, causing the transmission worm wheel 418 to control the synchronous rotation of the power conveyor shaft 417. The power conveyor shaft 417 drives the power wheel 503 to rotate, which in turn drives the conveyor belt 502. The conveyor belt 502 then transports the sheet metal to the top of the material platform 401. After the sheet metal is transported, the first motor 416 rotates in the opposite direction. The conveyor belt 502 is retracted into the material carrier platform 401. The metal sheet is supported and positioned by the support pins on the surface of the plate support base 402. The robotic arm 2 moves the laser emitter 201 to cut the metal sheet. During metal cutting, the power fan 304 is activated, which creates negative pressure in the suction ring 303. The suction ring 303 sucks up the debris and dust generated by laser burning. The waste gas sucked up by the suction ring 303 is transported to the purification box 301 through the connecting pipe 302. The sucked waste gas passes through the filter adsorption block 306, which filters and intercepts the debris and particulate matter inside the waste gas, reducing the pollution of the waste gas generated by laser cutting to the environment and improving the environmental protection performance of laser cutting. Through the above device, the convenience of handling large plates is reduced, and the waste gas generated by cutting can be purified and filtered, improving the convenience and safety of laser cutting.
