Description

[0001] Technical field.

[0002] The present invention relates to the field of laser cutting technology, and more specifically, to a laser cutting and punching device. Background Art

[0003] Laser cutting and drilling device is a high-tech industrial equipment, which uses the high energy density of laser beam to irradiate the material after focusing, so that the material can be quickly melted, gasified and evaporated, thereby forming holes. Laser drilling equipment mainly includes laser, processing head, cooling system, CNC system, operation panel, etc. The processing head focuses the laser beam on the position where the hole needs to be punched on the material. After selecting the appropriate process parameters, the required hole can be processed by the light pulse emitted by the laser.

[0004] Laser cutting works in a continuous or repeated pulse mode. During the cutting process, the laser beam is focused into a very small light spot (diameter <0.1mm), so that the focus reaches a very high power density. At this time, the heat input by the beam far exceeds the part reflected, conducted and diffused by the material, and the material is quickly heated to the melting and vaporization temperature. At the same time, a high-speed airflow blows the melted or vaporized material out from the bottom of the material from a coaxial or non-coaxial direction. With the relative movement of the beam and the material, the hole gradually expands to form a very narrow cutting seam. However, problems such as heat concentration, auxiliary airflow pressure disorder, improper focus position and improper cutting speed will affect the processing quality of the plate; In the prior art, when the laser cutting equipment is drilling, auxiliary gas is usually used to blow the residue out of the workpiece and take away the heat on the surface of the residue. However, the residue that is not cooled in time will adhere to the bottom of the plate to form slag, and the residue that is separated from the plate will also adhere to the surface of the workbench after the temperature drops, resulting in the need to remove the residue later.

[0013] Furthermore, a scraping assembly is provided inside the workbench, and the scraping assembly includes a scraper fixedly connected to the front and rear sides of the lower end of the movable frame in parallel.

[0014] Furthermore, the scraper is in an "L" shape and is arranged at an angle. The front and rear sides of the lower end of the storage groove are fixedly connected to landslides.

[0018] (2) The present invention guides and collects the residues by means of a movable frame.

[0019] (3) The support platform of the present invention can be washed by water mist after being tilted, so that the residue falls off. Since the support bar can block the water mist sprayed from the nozzle after being flipped to both sides, the water mist sprayed from the nozzle can be directly sprayed onto the support bar and wash away the residue attached to the side of the support bar, thereby preventing the residue attached to the side of the support bar from being difficult to handle after the water dries.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 8 A laser cutting and punching device comprises a workbench 1 and an electric guide rail 11 arranged on the front of the vertical part of the workbench 1, a laser punching member 12 is slidably arranged inside the electric guide rail 11, and a water mist spraying member 2 is arranged inside the workbench 1; The water mist spraying component 2 includes a movable groove 21 opened on the back side of the upper end of the workbench 1, a connecting plate 22 is fixedly connected to the lower side of the electric guide rail 11, the lower half of the connecting plate 22 is slidably connected in the movable groove 21, a nozzle 23 is arranged at the lower front end of the connecting plate 22, a water-gas mixing switch 24 is arranged inside the workbench 1, a conduit 241 is arranged on the upper side of the water-gas mixing switch 24, the other end of the conduit 241 passes through the connecting plate 22 and is fixedly connected to the nozzle 23, a water pump 242 is arranged on the back side of the left end of the water-gas mixing switch 24, an air pump 243 is arranged on the back side of the right end of the water pump 242, and a storage groove 25 is opened at the upper end of the workbench 1.

[0024] The nozzle 23 is in the shape of an elongated strip. The water-gas mixing switch 24 is connected to the nozzle 23 via a conduit 241 . The conduit 241 is received inside the movable groove 21 . The movable groove 21 is in the shape of a “T”. The movable groove 21 is connected to the receiving groove 25 . The nozzle 23 is located inside the receiving groove 25 .

[0025] By adopting the above technical solution, after the workpiece is placed on the workbench 1, the electric guide rail 11 is started to adjust the position of the laser punching member 12. As the electric guide rail 11 starts to run, the electric guide rail 11 on the inner side will drive the connecting plate 22 to move synchronously with it, and while the connecting plate 22 slides inside the moving groove 21, it will also drive the nozzle 23 to follow the movement, so that the nozzle 23 moves synchronously with the laser punching member 12, and the nozzle 23 is always under the laser punching member 12. After the laser punching member 12 punches the workpiece for a period of time, the water pump 242 and the air pump 243 cooperate to inject the water source containing gas into the water-gas mixing switch 24. Because the water-gas mixing switch 24 is connected to the nozzle 23 through the conduit 241, the water mist is finally sprayed out from the nozzle 23 and sprayed to the bottom of the workpiece; It should be noted that the compressed air pressure and water flow rate are set according to the thickness and material of the processed plate. Generally speaking, the compressed air pressure is 1 / 3-1 / 5 of the thickness of the cut plate, and the water flow rate is 1 / 5-1 / 15 of the thickness of the cut plate. During the laser drilling process, the sprayed water mist can cool the residue and solidify it into particles. Since the residue cut out of the workpiece can be cooled by water mist during the drilling process, the residue is prevented from adhering to the bottom of the workpiece due to its own heat. The cooled residue will adhere to the bottom of the workpiece with the help of the adhesion of water. After adjusting the compressed air pressure and water flow rate, the residue can be washed away, effectively reducing the probability of slag and dross formation.

[0026] like Figure 2 and Figures 4 to 8 As shown, a guide assembly 26 is provided inside the workbench 1 , and the guide assembly 26 includes a movable frame 261 slidably connected inside the receiving groove 25 .

[0027] The rear end of the movable frame 261 is slidably connected to the inner front side of the movable groove 21, and the movable frame 261 is sleeved on the outer side of the nozzle 23. The left and right sides of the movable frame 261 are provided with drainage slopes 262. The nozzle 23 is located between the two drainage slopes 262, and the nozzle 23 opens upward.

[0028] By adopting the above technical solution, as the connecting plate 22 drives the nozzle 23 to move, the movable frame 261 arranged on the outside of the nozzle 23 will move together with the nozzle 23. When the sprayed water mist carries the residue and falls, it will fall on the movable frame 261. At this time, the drainage slope 262 inside the movable frame 261 will guide and converge the water source, and the movable frame 261 moves with the connecting plate 22, so that when the laser punching part 12 moves to any position, the movable frame 261 is always below the laser punching part 12 and guides the water source and the residue. Since the movable frame 261 is outside the nozzle 23 and always moves synchronously with the nozzle 23, the water mist sprayed by the nozzle 23 can guide the residue under the workpiece when it falls, so as to prevent the residue from splashing onto the surface of the workbench 1 and the area outside the workbench 1, thereby providing convenience for subsequent residue sorting.

[0029] like Figures 1 to 3 As shown, a flushing assembly 27 is provided on both the inner and outer sides of the workbench 1 , and the flushing assembly 27 includes a pressure sensor 271 arranged on the right side inside the electric guide rail 11 .

[0030] A servo motor 272 is arranged on the front side of the workbench 1, and a rotating rod 2721 is fixedly connected to the output end of the servo motor 272. The interior of the storage slot 25 is arranged in a horizontal linear array and is rotatably connected to support bars 273. The front end of the support bar 273 at the rightmost end is fixedly connected to the rear end of the rotating rod 2721. The opposite surfaces of the left and right adjacent support bars 273 are arranged in a rectangular array and are fixedly connected to hinge seats 274. A connecting rod 275 is hingedly connected between the left and right adjacent hinge seats 274. A controller 276 is arranged on the front side of the workbench 1, and the controller 276 and the servo motor 272 are both electrically connected to an external power supply.

[0031] By adopting the above technical solution, when the electric guide rail 11 moves the laser punching part 12 to the right front, the laser punching part 12 will contact the pressure sensor 271, and then the pressure sensor 271 sends a signal to the controller 276, and then the controller 276 controls the servo motor 272 to operate. When the servo motor 272 drives the rotating rod 2721 to rotate forty-five to ninety degrees clockwise or counterclockwise, the support bar 273 originally used to support the workpiece will be in an inclined state inside the storage slot 25. When the support bar 273 located on the far right and fixed to the rotating rod 2721 starts to rotate under the drive of the servo motor 272, because the two adjacent support bars 273 are hinged to the connecting rod 275 through the hinge seat 274, when the right support bar 273 pushes the left support bar 273 through the connecting rod 275, the corresponding support bar 273 The lower connecting rod 275 will pull the lower side of the left support bar 273, and the remaining support bars 273 will be pulled by the connecting rod 275. The deflection direction of the support bar 273 is closely related to the rotation direction of the rightmost support bar 273 driven by the servo motor 272. When all the support bars 273 are tilted, the electric guide rail 11 drives the connecting rod 275 to move from the right to the left, and then the nozzle 23 sprays water mist, and the water mist sprayed by the nozzle 23 will be directly sprayed to the side of the support bar 273, and the residue attached to the side of the support bar 273 will be washed away. Then the servo motor 272 rotates in the opposite direction, so that the support bar 273 tilts toward the other side. At this time, the electric guide rail 11 drives the nozzle 23 to move from left to right through the connecting rod 275, so that the water mist sprayed by the nozzle 23 will flush the residue on the other side of the support bar 273. Since the support bar 273 can block the water mist sprayed by the nozzle 23 after flipping to both sides, the water mist sprayed by the nozzle 23 can be directly sprayed onto the support bar 273 and flush the residue attached to the side of the support bar 273, avoiding the residue attached to the side of the support bar 273 from being difficult to handle after the water dries.

[0032] like Figures 4 to 8 As shown, a scraping assembly 28 is provided inside the workbench 1 , and the scraping assembly 28 includes a scraper 281 fixedly connected to the front and rear sides of the lower end of the movable frame 261 in parallel.

[0033] The scraper 281 is in an "L" shape and is arranged at an angle. The front and rear sides of the lower end of the storage groove 25 are fixedly connected with slides 282. A merging groove 283 is opened on the lower side of the interior of the storage groove 25. The merging groove 283 is located between the two slides 282. The lower side of the scraper 281 is in sliding contact with the inclined surface of the slide 282.

[0034] By adopting the above technical solution, when the movable frame 261 moves to the left or right, the scraper 281 below the movable frame 261 contacts the landslide 282 inside the storage groove 25, so that the residue entering the movable frame 261 will reach the top of the landslide 282 after passing through the movable frame 261, and will be located between the left and right corresponding scrapers 281. As the movable frame 261 drives the scraper 281 to move, the residue staying above the landslide 282 will be shoveled up by the scraper 281 when contacting the landslide 282, and the residue will be pushed by the accumulated moisture, so that the residue gradually flows into the confluence groove 283 with the help of the moisture. Since the scraper 281 can shovel up the moisture on the surface of the landslide 282 during the movement, and the shoveled moisture can be used to flush and guide the residue attached to the surface of the landslide 282, so as to facilitate the collection of the residue, and the residue can be quickly removed to ensure the cleanliness of the surface of the storage groove 25 and the landslide 282.

[0035] like Figures 4 to 6 As shown, the inner and outer sides of the workbench 1 are jointly provided with a collecting assembly 29 , and the collecting assembly 29 includes a collecting frame 291 slidably connected to the lower side of the inner part of the merging groove 283 .

[0036] A pull rod 292 is fixedly connected to the left side of the collection frame 291, and partitions 293 are fixedly connected to the left and right sides of the collection frame 291. Through holes 294 are arranged in a rectangular array on the left and right sides of the collection frame 291, and the single-sided through holes 294 form a group. The partition 293 is located between the two groups of through holes 294. A hollow cavity 295 is opened in the lower part of the collection frame 291, and a heating strip 296 is arranged inside the hollow cavity 295. The through hole 294 is connected to the hollow cavity 295.

[0037] By adopting the above-mentioned technical scheme, the residue shoveled out by the scraper 281 will flow into the interior of the collecting frame 291 through the confluence groove 283. Since the partition 293 divides the interior of the collecting frame 291, the position where the through hole 294 is opened in the collecting frame 291 is separated. At the same time, the heat generated by the heating strip 296 in the hollow cavity 295 after operation can be directly discharged into the interior of the storage groove 25 through the through hole 294, and the residual moisture in the storage groove 25 is dried, and the moisture collected in the collection frame 291 is also dried. Since the collection frame 291 can collect the residue and moisture guided by the confluence groove 283, and the heat generated by the heating strip 296 can dry the moisture, the moisture and the residue are separated in time to facilitate the quick cleaning of the residue. At the same time, the heat generated by the heating strip 296 can also dry the moisture in the storage groove 25, thereby preventing the residual moisture from breeding bacteria.

[0038] Working principle: After placing the workpiece on the workbench 1, start the electric guide rail 11 to adjust the position of the laser punching part 12, and the electric guide rail 11 on the inside will drive the connecting plate 22 to move synchronously with it. When the connecting plate 22 slides inside the moving groove 21, it will drive the nozzle 23 to follow the movement, so that the nozzle 23 moves synchronously with the laser punching part 12. After the laser punching part 12 punches the workpiece for a period of time, the water pump 242 and the air pump 243 cooperate to inject gas and water into the water-gas mixing switch 24. Because the water-gas mixing switch 24 is connected to the nozzle 23 through the conduit 241, the water mist is finally sprayed out from the nozzle 23 and sprayed to the bottom of the workpiece. During the laser drilling process, the sprayed water mist can cool the residue and solidify it into particles. With the connecting plate 2 2 drives the nozzle 23 to move, and the movable frame 261 arranged on the outside of the nozzle 23 will move together with the nozzle 23, and the water mist carrying the residue will fall on the top of the movable frame 261. At this time, the drainage slope 262 inside the movable frame 261 will guide and converge the water source, and guide the water source and the residue. When the electric guide rail 11 moves the laser punching member 12 to the right front, the laser punching member 12 will contact the pressure sensor 271, and then the pressure sensor 271 sends a signal to the controller 276, and then the controller 276 controls the servo motor 272 to operate. When the servo motor 272 drives the rotating rod 2721 to rotate clockwise or counterclockwise forty-five to ninety degrees, the support bar 273 originally used to support the workpiece will be in an inclined state inside the storage slot 25. When the position After the support bar 273 fixed to the rotating rod 2721 on the far right starts to rotate under the drive of the servo motor 272, since the connecting rod 275 is hingedly connected between the two adjacent support bars 273 through the hinge seat 274, when the right support bar 273 pushes the left support bar 273 through the connecting rod 275, the connecting rod 275 on the lower side of the corresponding support bar 273 will pull the lower side of the left support bar 273, and the remaining support bars 273 will be pulled by the connecting rod 275. When all the support bars 273 are tilted, the electric guide rail 11 drives the connecting rod 275 to move from the right to the left, and then the nozzle 23 sprays water mist, and the water mist sprayed by the nozzle 23 will be directly sprayed to the side of the support bar 273, and the residue attached to the side of the support bar 273 will be washed away. , then the servo motor 272 rotates in the opposite direction, so that the support bar 273 tilts toward the other side. At this time, the electric guide rail 11 drives the nozzle 23 to move from left to right through the connecting rod 275, so that the water mist sprayed by the nozzle 23 will flush the residue on the other side of the support bar 273. After the movable frame 261 moves, the residue entering the movable frame 261 will reach the top of the landslide 282 after passing through the movable frame 261, and will be located between the left and right corresponding scrapers 281. As the movable frame 261 drives the scraper 281 to move, the residue staying on the top of the landslide 282 will be shoveled up by the scraper 281 when it contacts the landslide 282, and the residue will be pushed by the accumulated moisture, so that the residue gradually flows into the confluence groove 283 through the moisture, and then flows into the inside of the collection frame 291.Then, it enters the area between the partition 293 and the collection frame 291. At the same time, the heat generated by the heating strip 296 in the hollow cavity 295 after operation can be directly discharged into the storage tank 25 through the through hole 294, and the residual moisture in the storage tank 25 is dried, and the moisture collected in the collection frame 291 is also dried.

[0039] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
