Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to an environmentally friendly, automatic dust removal laser cutting fixture. Background Technology

[0002] Laser cutting is a high-precision thermal cutting method that uses a high-power-density laser beam to irradiate a workpiece. The laser beam emitted by the equipment causes the irradiated material to melt, vaporize, ablate, or reach its ignition point rapidly. At the same time, a high-speed airflow coaxial with the beam blows away the molten material, thereby achieving the cutting of the workpiece.

[0003] Publication No. CN108838568A discloses a laser cutting positioning fixture, including a base plate. The four corners of the base plate are detachably connected to a fixing rod via a first connector. A fixing frame is fixedly connected to the top of the base plate. A first positioning plate, a second positioning plate, a third positioning plate, and a fourth positioning plate are detachably connected to the side wall of the fixing frame via a second connector. Each of the four corners of the first, second, third, and fourth positioning plates is provided with a connecting pipe, and a water flow groove is formed on the side wall of the connecting pipe. The above application uses the second connector to detachably connect the first, second, third, and fourth positioning plates to the fixing frame, so that the detachable positioning plates ensure that no error occurs each time the product is placed.

[0004] Although the aforementioned applications and prior art can ensure that no errors occur during laser cutting and improve the cutting accuracy, when cutting wooden workpieces, carbonization occurs at the cutting edge of the wooden workpiece, which leads to a decrease in the quality of the cut workpiece. To prevent this, masking tape is usually covered on the top of the workpiece to avoid carbonization. During the masking tape covering process, since there may be a small amount of foreign matter on the top of the workpiece, the foreign matter will cause a bulge at the bottom of the masking tape, resulting in a small area of ​​bulge around it. This makes it easy for carbonization to occur during the subsequent cutting process. In addition, during the masking tape covering process, a small number of air bubbles will form between the masking tape and the workpiece covering surface. The formation of air bubbles will also lead to carbonization during the subsequent cutting process. Therefore, this invention proposes an environmentally friendly automatic dust removal laser cutting fixture. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an environmentally friendly, automatically dust-removing laser cutting fixture. It offers advantages such as preventing carbonization, preventing protrusions, and preventing air bubbles. This solves the problem that, when cutting wooden workpieces as described in the aforementioned applications and existing technologies, carbonization occurs at the cutting edges, leading to a decline in workpiece quality. To prevent this, masking tape is typically used to cover the top of the workpiece. However, during the masking tape application process, a small amount of foreign matter may be present on the top of the workpiece. This foreign matter can cause protrusions at the bottom of the masking tape, resulting in small bulges around the workpiece. This can easily lead to carbonization during subsequent cutting. Furthermore, the masking tape can create small air bubbles on the workpiece surface, which can also contribute to carbonization during subsequent cutting.

[0006] To achieve the aforementioned objectives of avoiding carbonization, preventing protrusions, and preventing bubbles, this invention provides the following technical solution: an environmentally friendly, automatically dust-removing laser cutting fixture, comprising: a fixture table and a laser cutting head disposed inside the fixture table.

[0008] Furthermore, the laying assembly also includes an air supply cylinder fixedly connected inside the protective shell and an air storage cylinder fixedly connected inside the protective shell. The pusher is slidably connected inside the air supply cylinder, and the air supply cylinder and the air storage cylinder are connected by a connecting pipe.

[0009] Furthermore, a first one-way valve is provided on the surface of the connecting pipe, a pressure relief valve is provided at one end of the gas storage cylinder, the gas storage cylinder and the fixed cylinder are connected through a gas supply pipe, a lower cutter is fixedly connected to the surface of the placement platform, and an upper cutter is fixedly connected to the top of the placement frame.

[0010] Furthermore, the anti-protrusion assembly includes a second screw plate threaded to the surface of the drive screw and a fixed rack fixedly connected to the bottom of the protective shell. The second screw plate is slidably connected to the bottom of the protective shell, and a connecting box is fixedly connected to the bottom of the second screw plate.

[0011] Furthermore, the connecting box is rotatably connected to a rotating rod and a turn rod. A drive gear and a storage wheel are fixedly connected to the surface of the rotating rod. The drive gear meshes with a fixed rack for transmission. A pay-off wheel is fixedly connected to the surface of the turn rod. A pull rope is provided on the surface of the pay-off wheel. The end of the pull rope away from the pay-off wheel is fixedly connected to the surface of the storage wheel.

[0012] Furthermore, a turntable is fixedly connected to one end of the rotating rod, a fixed rod is fixedly connected to the surface of the turntable, an air transmission cylinder is fixedly connected inside the connecting box, a sealing disc is slidably connected inside the air transmission cylinder, a transmission bar is hinged to the top of the sealing disc, the end of the transmission bar away from the sealing disc is rotatably connected to the surface of the fixed rod, and a second one-way valve is provided on the surface of the sealing disc.

[0015] Furthermore, the surface of the tooling table is provided with a control panel, which is electrically connected to the drive motor. The top of the tooling table is provided with an audible and visual warning light, and the bottom of the mobile platform is provided with a smoke exhaust mechanism.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides an environmentally friendly automatic dust removal laser cutting fixture, which has the following beneficial effects: 1. This environmentally friendly, automatic dust-removing laser cutting fixture, through the use of the laying components, starts the drive motor via the control panel. The drive motor drives the first screw plate to move via the drive screw, which in turn moves the fixed cylinder and the push rod. The fixed cylinder, through the extension cylinder, moves the placement frame and the tape roller, gradually covering the top of the workpiece with masking tape. As the push rod moves, it moves the push plate inside the air supply cylinder, allowing air from inside the air supply cylinder to be transported to the air storage cylinder through the connecting pipe. When the tape roller is no longer on top of the workpiece, the pressure relief valve opens, allowing air from inside the air storage cylinder to enter the fixed cylinder through the air supply pipe. This causes the extension cylinder to move down via the placement frame, moving the tape roller and the upper cutter downwards, covering the top of the workpiece with masking tape. During the descent of the upper cutter, it works in conjunction with the lower cutter to cut the masking tape, thus covering the cut surface of the workpiece with the masking tape and preventing carbonization.

[0017] 2. This environmentally friendly automatic dust removal laser cutting fixture, through the combined use of the laying component and the anti-protrusion component, when the drive screw rotates, the drive screw drives the connecting box to move through the second screw plate, causing the fixed rack to drive the rotating rod to rotate through the drive gear. When the rotating rod rotates, it collects the pull rope on the surface of the feeding wheel, causing the feeding wheel to drive the turntable to rotate through the rotating rod. The turntable drives the sealing disc to move inside the air transmission cylinder through the fixed rod and the transmission bar, so that the air inside the air transmission cylinder is continuously delivered to the main pipe through the air transmission pipe, and then sprayed out through the nozzle. As the connecting box moves continuously, the air sprayed out by the nozzle blows away foreign objects on the top of the workpiece, thereby preventing foreign objects from causing the masking tape to bulge during the laying process, thus achieving the effect of preventing bulging.

[0018] 3. This environmentally friendly automatic dust removal laser cutting fixture, through the combined use of the laying component and the bubble-avoiding component, drives the screw to rotate. When the screw rotates, it drives the storage block to move through the third screw plate. The storage block then drives several scrapers to move on top of the masking tape through the extension block. Due to the presence of the second spring, the extension block drives the scrapers to make close contact with the top of the masking tape. As the storage block gradually moves, the air bubbles at the bottom of the masking tape are squeezed out, thereby achieving the effect of avoiding air bubbles.

[0023] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 9 An environmentally friendly, automatically dust-removing laser cutting fixture includes: a fixture table 1 and a laser cutting head 134 disposed inside the fixture table 1. A fixed platform 13 is fixedly connected inside the tooling table 1. A protective shell 14 is fixedly connected inside the tooling table 1. A control panel 11 is provided on the surface of the tooling table 1. The control panel 11 is electrically connected to the drive motor 21. An audible and visual warning light 12 is provided on the top of the tooling table 1. The laying component 2, located inside the protective shell 14, is used to lay masking tape on the workpiece to be cut, thereby preventing carbonization at the edges of the workpiece. The laying component 2 includes a first screw plate 212 slidably connected inside the protective shell 14. A fixing cylinder 22 is fixedly connected to the bottom of the first screw plate 212. An extension cylinder 222 is slidably connected inside the fixing cylinder 22. A placement frame 223 is fixedly connected to the bottom of the extension cylinder 222. A tape roller 224 is rotatably connected inside the placement frame 223. The laying component 2 also includes a drive motor 21 fixedly connected to the back of the tooling table 1. A drive screw 211 is fixedly connected to the output end of the drive motor 21. The first screw plate 212 is threadedly connected to the surface of the drive screw 211. The fixing cylinder 22... The first spring 221 is fixedly connected inside the first screw plate 212. The top of the extension cylinder 222 is fixedly connected to the bottom of the first spring 221. The push rod 23 is fixedly connected to the surface of the first screw plate 212. One end of the push rod 23 is fixedly connected to the push disk 231. The laying component 2 also includes an air supply cylinder 24 and an air storage cylinder 25 fixedly connected inside the protective shell 14. The push disk 231 is slidably connected inside the air supply cylinder 24. The air supply cylinder 24 and the air storage cylinder 25 are connected through a connecting pipe 241. A first one-way valve 251 is provided on the surface of the connecting pipe 241. A pressure relief valve 253 is provided at one end of the air storage cylinder 25. The air storage cylinder 25 and the fixed cylinder 22 are connected through an air supply pipe 252. The anti-bulge component 3 is located inside the protective shell 14 and is used to blow away foreign objects on the top of the workpiece to be cut to prevent the formation of bulges after the masking tape is laid. The bubble-avoiding component 4 is located inside the protective shell 14 and is used to remove air bubbles formed inside the masking tape after it has been laid, so as to prevent the workpiece from carbonizing during the cutting process. It should be noted that the inner wall of the tooling table 1 is equipped with a robotic arm for limiting the masking tape. The robotic arm is existing technology and will not be described in detail here. The robotic arm limits and fixes one end of the masking tape. Therefore, when the tape roller 224 moves, the masking tape on the surface of the tape roller 224 can be located at the top of the workpiece cutting surface, and the width of the workpiece to be cut is less than the distance between the first screw plate 212 and the air supply cylinder 24. The air supply pipe 252 is a telescopic flexible hose. To prevent carbonization at the edges of the workpiece, the drive motor 21 is activated via the control panel 11. The drive motor 21 moves the first screw plate 212 via the drive screw 211, causing the first screw plate 212 to move the fixed cylinder 22 and the push rod 23. The fixed cylinder 22 moves the placement frame 223 and the tape roller 224 via the extension cylinder 222, gradually covering the top of the workpiece with masking tape on the surface of the tape roller 224. As the push rod 23 moves, it drives the push disc 231 to move inside the air supply cylinder 24, allowing the air inside the air supply cylinder 24 to... The air is supplied to the inside of the air storage cylinder 25 through the connecting pipe 241. When the tape roller 224 is no longer on top of the workpiece, the pressure relief valve 253 opens, allowing the air inside the air storage cylinder 25 to enter the inside of the fixed cylinder 22 through the air supply pipe 252. This causes the extension cylinder 222 to drive the tape roller 224 and the upper cutter 225 to descend through the placement frame 223, so that the masking tape covers the top of the workpiece. Because the masking tape covers the top of the workpiece, when the laser cutting head 134 cuts the workpiece, there will be no large amount of carbonization at the edge of the workpiece. For a specific embodiment two, please refer to Figures 1 to 8 Based on the environmentally friendly automatic dust removal laser cutting fixture provided in Specific Embodiment 1, this embodiment provides a further technical solution: A lower cutter 132 is fixedly connected to the surface of the placement platform 131, and an upper cutter 225 is fixedly connected to the top of the placement frame 223; When the masking tape needs to be cut, after air enters the interior of the fixed cylinder 22, as the air pressure inside the fixed cylinder 22 increases, the extension cylinder 222 drives the placement frame 223 to descend, which in turn drives the upper cutter 225 to descend. During the descent of the upper cutter 225, the upper cutter 225 and the lower cutter 132 cooperate to cut the masking tape on the surface of the tape roller 224. For a specific embodiment three, please refer to Figures 1 to 13Based on the environmentally friendly automatic dust removal laser cutting fixture provided in Specific Embodiment Two, this embodiment provides a further technical solution: The anti-protrusion component 3 includes a second screw plate 31 threadedly connected to the surface of the drive screw 211 and a fixed rack 32 fixedly connected to the bottom of the protective shell 14. The second screw plate 31 is slidably connected to the bottom of the protective shell 14. A connecting box 311 is fixedly connected to the bottom of the second screw plate 31. A rotating rod 33 and a rotating rod 34 are rotatably connected inside the connecting box 311. A drive gear 331 and a collecting wheel 332 are fixedly connected to the surface of the rotating rod 33. The drive gear 331 meshes with the fixed rack 32 for transmission. A wire feeding wheel 341 is fixedly connected to the surface of the rotating rod 34. A pull rope 342 is provided on the surface of the wire feeding wheel 341. The end of the pull rope 342 away from the wire feeding wheel 341 is fixedly connected to the collecting wheel 332. On the surface of the connecting box 311, a turntable 343 is fixedly connected to one end of the rotating rod 34, and a fixed rod is fixedly connected to the surface of the turntable 343. An air transmission cylinder 35 is fixedly connected inside the connecting box 311, and a sealing disc 351 is slidably connected inside the air transmission cylinder 35. A transmission bar 344 is hinged to the top of the sealing disc 351, and the end of the transmission bar 344 away from the sealing disc 351 is rotatably connected to the surface of the fixed rod. A second one-way valve is provided on the surface of the sealing disc 351. A telescopic rod is fixedly connected to the bottom of the connecting box 311, and a main pipe 353 is fixedly connected to the bottom of the telescopic rod. Several nozzles 354 are fixedly connected to the surface of the main pipe 353, and the main pipe 353 and the air transmission cylinder 35 are connected through an air transmission pipe 352. To prevent foreign objects on the top of the workpiece from causing the masking tape to bulge, when the drive screw 211 rotates, the drive screw 211 drives the connecting box 311 to move through the second screw plate 31. This causes the fixed rack 32 to drive the rotating rod 33 to rotate through the drive gear 331. When the rotating rod 33 rotates, it collects the pull rope 342 on the surface of the feed wheel 341. This causes the feed wheel 341 to drive the turntable 343 to rotate through the rotating rod 34. The turntable 343 drives the sealing disc 351 to move inside the air transmission cylinder 35 through the fixed rod and the transmission bar 344. This allows the air inside the air transmission cylinder 35 to be continuously delivered to the main pipe 353 through the air transmission pipe 352, and then sprayed out through the nozzle 354. As the connecting box 311 moves continuously, the air sprayed out by the nozzle 354 blows away the foreign objects on the top of the workpiece, thus preventing foreign objects from causing the masking tape to bulge during the laying process, which would affect the subsequent cutting effect. For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 14 Based on the environmentally friendly automatic dust removal laser cutting fixture provided in Specific Embodiment Three, this embodiment provides a further technical solution: The bubble-avoiding component 4 includes a third screw plate 41 threadedly connected to the surface of the drive screw 211. A storage block 411 is fixedly connected to the bottom of the third screw plate 41. A second spring is fixedly connected inside the storage block 411. An extension block 412 is slidably connected inside the storage block 411. The top of the extension block 412 is fixedly connected to the bottom of the second spring. Several scrapers 42 are fixedly connected to the bottom of the extension block 412. When it is necessary to avoid air bubbles forming on the contact surface between the masking tape and the workpiece, the drive screw 211 rotates and drives the storage block 411 to move through the third screw plate 41. The storage block 411 drives several scrapers 42 to move on the top of the masking tape through the extension block 412. Due to the presence of the second spring, the extension block 412 drives the scrapers 42 to make tight contact with the top of the masking tape. As the storage block 411 moves gradually, the air bubbles at the bottom of the masking tape are squeezed out by the scrapers 42. Therefore, when the laser cutting head 134 cuts the workpiece, there will be no gaps in the masking tape that would cause carbonization of the workpiece. For a specific implementation example, please refer to Implementation Example 5. Figures 1 to 3 Based on the environmentally friendly automatic dust removal laser cutting fixture provided in Specific Embodiment Four, this embodiment provides a further technical solution: The fixed platform 13 is provided with a placement platform 131 on its top, and a movable platform 133 is slidably connected to the top of the fixed platform 13. A smoke exhaust mechanism 135 is provided at the bottom of the movable platform 133. It should be noted that the smoke exhaust mechanism 135 includes a bamboo-joint omnidirectional flexible tube fixedly connected to the surface of the laser cutting head 134 via a support plate. The bottom end of the bamboo-joint omnidirectional flexible tube is fixedly connected to a suction nozzle, which has an irregular streamlined design. The top of the bamboo-joint omnidirectional flexible tube is fixedly connected to a dust removal flexible tube, and a dust removal fan is installed on the top of the dust removal flexible tube. When the workpiece needs to be cut, after the cutting surface of the top of the workpiece is covered with masking tape, the placement table 131 is moved out of the bottom of the protective shell 14, and then the laser cutting head 134 is moved to the cutting surface of the top of the workpiece by the moving platform 133. The workpiece is cut by the laser cutting head 134, and the smoke generated during the cutting process is discharged into the tooling table 1 through the smoke exhaust mechanism 135.

[0025] Working principle: During use, the workpiece is placed on top of the placement table 131. To prevent carbonization at the edges of the workpiece, the drive motor 21 is started via the control panel 11. The drive motor 21 drives the first screw plate 212 to move via the drive screw 211. The first screw plate 212 then moves the fixed cylinder 22 and the push rod 23. The fixed cylinder 22 moves the placement frame 223 and the tape roller 224 via the extension cylinder 222. This gradually covers the top of the workpiece with the masking tape on the surface of the tape roller 224. As the push rod 23 moves, it drives the push disc 231 to move inside the air supply cylinder 24, allowing the air inside the air supply cylinder 24 to be transported to the air storage cylinder 25 through the connecting pipe 241. When the tape roller 224 is no longer on top of the workpiece, the pressure relief valve 2... 53 is opened, allowing air from the air reservoir 25 to enter the fixed cylinder 22 through the air supply pipe 252. This causes the extension cylinder 222 to descend via the placement frame 223, pulling the tape roller 224 and the upper cutter 225 downwards, covering the top of the workpiece with masking tape. Because the masking tape covers the top of the workpiece, when the laser cutting head 134 cuts the workpiece, there will be no excessive carbonization at the edges. When the masking tape needs to be cut, as air enters the fixed cylinder 22, the air pressure inside the fixed cylinder 22 continuously increases, causing the extension cylinder 222 to descend, pulling the placement frame 223 downwards. This, in turn, causes the placement frame 223 to descend, pulling the upper cutter 225 downwards. During the descent of the upper cutter 225, the upper cutter 225 and the lower cutter 1... 32 work together to cut the masking tape on the surface of the tape roller 224. When foreign objects are present on the top of the workpiece causing the masking tape to bulge, when the drive screw 211 rotates, it drives the connecting box 311 to move via the second screw plate 31. This causes the fixed rack 32 to drive the rotating rod 33 to rotate via the drive gear 331. As the rotating rod 33 rotates, it collects the pull rope 342 on the surface of the feed wheel 341, causing the feed wheel 341 to drive the turntable 343 to rotate via the rotating rod 34. The turntable 343, through the fixed rod and transmission bar 344, drives the sealing disc 351 to move inside the air transmission cylinder 35, continuously supplying air from inside the air transmission cylinder 35 to the main pipe 353 via the air transmission pipe 352, and then through the nozzle 3. As the connecting box 311 moves, the air ejected from nozzle 354 blows away foreign objects on the top of the workpiece, thus preventing them from causing bulges in the masking tape during application and affecting subsequent cutting. To prevent air bubbles from forming on the contact surface between the masking tape and the workpiece, the drive screw 211 rotates, driving the collecting block 411 to move via the third screw plate 41. The collecting block 411 then moves several scrapers 42 via the extension block 412 on top of the masking tape. Due to the presence of the second spring, the extension block 412 and the scrapers 42 are in close contact with the top of the masking tape. As the collecting block 411 moves gradually, air bubbles at the bottom of the masking tape are squeezed out by the scrapers 42.Therefore, when the laser cutting head 134 cuts the workpiece, there will be no gaps in the masking tape that could cause carbonization. When cutting the workpiece, after the top of the workpiece is covered with masking tape, the placement table 131 is moved out of the bottom of the protective shell 14. Then, the moving platform 133 moves the laser cutting head 134 to the top of the workpiece for cutting. The laser cutting head 134 then cuts the workpiece, and the smoke generated during the cutting process is discharged from the tooling table 1 through the smoke exhaust mechanism 135.

It also allows for errors within a small angular range, such as within 10 degrees of assembly error. These can all be considered as parallel relationships.

[0029] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
