Description

Technical Field

[0001] The present invention relates to the field of laser cutting robots for sprues, and specifically to a laser cutting robot capable of recycling sprues. Background Technique

[0002] A sprue refers to the combined part of the frame and the part formed when the factory casts a model, also known as the runner, which means the inlet and outlet where the heat-melted liquid material flows. When cutting the sprue, a laser cutting robot can be used.

[0003] Chinese Patent with the related publication number CN218253516U discloses a carbon dioxide sprue laser cutting machine, including a carbon dioxide laser cutting machine. A collection mechanism is arranged on one side of the carbon dioxide laser cutting machine. A groove is formed on the surface of the carbon dioxide laser cutting machine. A telescopic mechanism is arranged on the surface of the carbon dioxide laser cutting machine. A protective plate is hinged on one side of the carbon dioxide laser cutting machine, and an observation window is installed on the surface of the protective plate.

[0004] In view of the above related technologies, the existing sprue laser cutting equipment forms a groove structure on the laser cutting machine, so that the cut sprues fall into the collection structure below through the groove. However, the positions of the sprues of existing different models are not fixed after production, and it is easy to have the problem that the sprues cannot pass through the groove. Moreover, when some large-sized models are cut for sprues, the cut sprues may be in the shape of a long strip and are not easy to fall off the carrier. After the laser cutting of the sprues is completed, it is necessary to manually remove the model and then remove the cut sprues on the carrier. In summary, the existing sprue laser cutting equipment is not easy to recycle large-sized sprues. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a laser cutting robot capable of recycling sprues to solve the technical problem that the existing sprue laser cutting equipment is not easy to recycle large-sized sprues.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A laser cutting robot capable of recycling sprues, including a box body. A laser cutting robotic arm is installed inside the box body. Four mounting columns are fixed inside the box body. A carrier is rotatably connected between the mounting columns on both sides of the box body. The rotating shaft of the carrier is simultaneously slidably connected in the first guide rail on the mounting column. A carrier slide rail for the carrier to slide away from one end of its rotating shaft is connected between the mounting columns at both ends of the box body. A flipping frame for loading and unloading is rotatably connected to the front end of the box body. A lifting block is rotatably connected to the middle of the rotating shaft of the carrier. The driving structure of the flipping frame can drive the lifting block to lift synchronously through a transmission component.

[0007] By adopting the above technical solution, when the rotating shaft of the carrier frame slides vertically upward, the two carrier frames in the box body can be rotated and opened, so that the large-sized nozzle on the carrier frame can smoothly fall into the box body for collection. At the same time, a turnover frame is rotatably arranged on one side of the box body, and a suction structure for sucking and holding workpieces is installed on the turnover frame. The linkage structure between the carrier frame and the turnover frame is used to realize turnover material taking while pouring the nozzle, and the carrier frame is reset when the material is placed by turnover.

[0008] The present invention is further configured such that a crushing box that synchronously rises and falls with the carrier frame is rotatably connected between the mounting columns on both sides of the box body, a collection box is slidably connected to the bottom end of the box body, and a crushing assembly for crushing the nozzle is movably connected to the bottom surface of the crushing box within the collection box.

[0009] By adopting the above technical solution, it is beneficial to prevent the large-sized nozzles from being stacked crosswise in the collection box and reducing the capacity of the collection box.

[0010] The present invention is further configured such that a first driving motor is installed on one side of the front end of the box body, the input end of a gear box is connected to the first driving motor, the gear box is provided with two output ends, one output end of the gear box is used to drive the turnover frame to rotate, and the other output end is connected to an electromagnetic clutch. The output end of the electromagnetic clutch is connected to a wire winding disc through a transmission belt, and a cable wound within the wire winding disc is used to connect a lifting block.

[0011] By adopting the above technical solution, when the electromagnetic clutch is energized by the first driving motor, while driving the turnover frame to turn over and discharge materials, the carrier frame and the crushing box are rotated to pour the nozzle.

[0012] The present invention is further configured such that connecting rods are rotatably connected to both ends of the rotating shaft of the crushing box, the other ends of the connecting rods are rotatably connected to the rotating shafts of the upper carrier frames, and crushing box slide rails for the sliding of the end of the crushing box away from the rotating shaft are connected between the mounting columns at both ends of the box body.

[0013] By adopting the above technical solution, the connecting rod structure enables the crushing box to move synchronously with the carrier frame.

[0014] The present invention is further configured such that a baffle inclined to the top surface of the crushing box is rotatably connected within the box body, and the bottom surface of the baffle is in contact with the top surface of the crushing box.

[0015] By adopting the above technical solution, the baffle plays a role in blocking small-sized nozzles from falling into both sides inside the box body, and can also scrape the top surface of the crushing box when the crushing box rotates.

[0016] The present invention is further configured such that a slide rail is arranged along the length direction in the middle of the bottom surface of the crushing box. A slider is slidably connected in the slide rail. A driving rod parallel to the slide rail is rotatably connected between the slide rails. The driving rod is used to drive the slider to slide, and one end thereof is connected to a second driving motor. The bottom end of the slider is rotatably connected to a gear. The gear meshes with a rack. The rack is fixedly connected in the crushing box and is parallel to the slide rail. The bottom end of the gear is fixedly connected to a third driving motor. The axis of the third driving motor is inclined to the axis of the gear, and a cutter head is connected to the output end.

[0017] By adopting the above technical solution, during the reciprocating movement of the slider in the crushing box, the large-sized sprue in the collection box can be effectively crushed.

[0018] The present invention is further configured such that a suction structure for sucking and holding a workpiece is connected to the flipping frame, and a support frame for supporting the flipping frame is fixedly connected to the front end of the box body.

[0019] By adopting the above technical solution, the workpiece is sucked and held by the suction structure on the flipping frame, thereby completing the loading and unloading of the workpiece.

[0020] The present invention is further configured such that a wire passing hole is arranged at the top end of the box body, and a pulley is connected above the lifting block. The cable in the cable reel sequentially passes through the wire passing hole and the pulley and then is connected to the lifting block.

[0021] By adopting the above technical solution, when the cable reel winds the cable, the lifting block rises under the tension of the cable. When the cable reel unwinds the cable, the lifting block descends under the gravity of the bearing frame and the crushing box itself.

[0022] The present invention is further configured such that a slideway is arranged at the bottom inside the box body corresponding to the position of the collection box.

[0023] By adopting the above technical solution, it is convenient for the collection box to be pulled out of the box body after being filled with sprue.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. In the present invention, two bearing frames are rotatably connected between the columns inside the box body. Tracks for the vertical sliding of the rotating shafts of the bearing frames are arranged on the columns, and the bearing frame slide rails connected between the columns are for the horizontal sliding of the end of the bearing frame away from the rotating shaft. When the rotating shaft of the bearing frame slides vertically upward, the two bearing frames inside the box body can be rotated and opened, so that the large-sized sprue on the bearing frame can smoothly fall into the box body for collection. At the same time, a flipping frame is rotatably arranged on one side of the box body, and a suction structure for sucking and holding a workpiece is installed on the flipping frame. The linkage structure between the bearing frame and the flipping frame is used to realize the flipping and taking of the material while pouring the sprue, and the bearing frame is reset when the material is flipped and placed.

[0026] 2. The present invention installs a crushing box that rotates synchronously with the carrier in the box body, and uses the crushing mechanism connected to the bottom surface of the crushing box to crush large-sized gate residues, avoiding the cross-stacking of gate residues falling into the collection box and occupying the space in the collection box, effectively improving the capacity of the collection box. And since the crushing box and the carrier can rotate synchronously, the small pieces of gate residues falling on the surface of the crushing box will also be dumped into the collection box during the flipping process of the crushing box;

[0027] 3. The present invention rotatably connects an inclined baffle structure in the box body, so that the bottom end of the baffle structure contacts the top surface of the crushing box. The baffle structure plays a role in preventing the gate residues from falling into other areas of the box body. At the same time, when the crushing box rotates, the baffle can also scrape the top surface of the crushing box to scrape off some small pieces of gate residues that may adhere to the top surface of the crushing box;

[0028] 4. The present invention sets a sliding track along the length direction in the crushing box, sets a slider in the sliding track, and rotatably connects a gear structure that cooperates with a rack below the slider. The driving motor of the crushing cutter head is inclined and connected below the gear structure. As the slider slides in the sliding track, the crushing cutter head can rotate along the axis of the gear and reciprocate along the length direction of the crushing box, thereby effectively improving the crushing effect of the crushing cutter head on the large pieces of gate residues in the collection box.

Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0042] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0043] Embodiment 1

[0044] A laser cutting robot capable of recycling the nozzle, as Figure 1-11As shown in the figure, it includes a box body 1. Inside the box body 1, a laser cutting robotic arm 3 is installed. Specifically, the laser cutting robotic arm 3 has sliding tracks in three directions: horizontal, longitudinal, and vertical. And the laser cutting head is arranged at the end of the two-axis industrial robotic arm, which can precisely cut the sprue on the surface of complex workpieces. Four mounting columns 2 are fixed inside the box body 1. Between the mounting columns 2 on both sides of the box body 1, a bearing frame 4 is rotatably connected. The two bearing frames 4 form a laser cutting bearing platform for placing workpieces. The rotating shaft of the bearing frame 4 is simultaneously slidably connected inside the first guide rail 201 on the mounting column 2. Between the mounting columns 2 at both ends of the box body 1, a bearing frame slide rail 203 for the end of the bearing frame 4 far from its own rotating shaft to slide is connected. In order to make the bearing frame 4 slide better inside the bearing frame slide rail 203, a roller is connected to the end of the bearing frame 4 far from its own rotating shaft. At the front end of the box body 1, a flipping frame 15 for loading and unloading is rotatably connected. The flipping frame 15 can flip into the box body 1 to pick up and place workpieces. It is easier for workers to pick up and place workpieces on the flipping frame 15 outside the box body 1 without having to put their hands into the box body 1. Two workers can stand on both sides of the flipping frame 15 respectively and be responsible for picking up and placing workpieces respectively. Or industrial robots can be installed on both sides of the flipping frame 15 to replace manual labor for picking up and placing materials. In the middle of the rotating shaft of the bearing frame 4, a lifting block 7 is rotatably connected. The driving structure of the flipping frame 15 can drive the lifting block 7 to lift synchronously through a transmission component. Specifically, the driving structure of the flipping frame 15 can make the lifting block 7 descend when the flipping frame 15 rotates into the box body 1 and rise when the flipping frame 15 leaves the box body 1 through the transmission component.

[0045] Please refer to Figure 1 、 Figures 6-7 As shown in the figure, on one side of the front end of the box body 1, a first driving motor 13 is installed. The input end of a gear box 12 is connected to the first driving motor 13. The gear box 12 has two output ends. Specifically, the two output ends of the gear box 12 are orthogonal to each other. One output end of the gear box 12 is used to drive the flipping frame 15 to rotate, and the other output end is connected to an electromagnetic clutch 11. Specifically, one output end of the gear box 12 is connected to the rotating shaft of the flipping frame 15, and the other output end is connected to the input end of the electromagnetic clutch 11 through a transmission shaft. The output end of the electromagnetic clutch 11 is connected to a wire reel 10 through a transmission belt. The cable 8 wound inside the wire reel 10 is used to connect the lifting block 7. Specifically, when the flipping frame 15 flips from the support frame 14 to above the bearing frame 4, the rotating shaft of the bearing frame 4 simultaneously slides from the bottom end to the top end inside the first guide rail 201. In order to prevent the bearing frame 4 from resetting when the wire reel 10 pays out the cable, the length of the first guide rail 201 is less than the width of the bearing frame 4. When the rotating shaft of the bearing frame 4 moves to the top end of the first guide rail 201, the bearing frame 4 is in an inclined state. When the first driving motor 13 drives the flipping frame 15 to flip and unload materials with the electromagnetic clutch 11 energized, the bearing frame 4 and the crushing box 5 are rotated to pour out the sprue.

[0046] Please refer to Figure 4 , a holding structure for holding the workpiece is connected to the flipping frame 15. Specifically, the holding structure includes a suction cup 1502. Specifically, at least two sliding adjustment rods 1501 are slidably connected to the flipping frame 15, and at least two suction cups 1502 are slidably connected to the sliding adjustment rods 1501 along the length direction. The sliding adjustment rods 1501 can slidably adjust their positions within the flipping frame 15, and the suction cups 1502 can slidably adjust their positions within the sliding adjustment rods 1501. By adjusting the number and positions of the suction cups 1502, workpieces of different sizes and shapes can be accommodated. A support frame 14 for supporting the flipping frame 15 is fixedly connected to the front end of the box body 1. Specifically, under the support of the support frame 14, the flipping frame 15 is in a horizontal state. The workpiece is held by the holding structure on the flipping frame 15, and thus the loading and unloading of the workpiece are completed.

[0047] Please refer to Figures 1-7 , a wire passing hole 101 is provided at the top of the box body 1, and a pulley 9 is connected above the lifting block 7. A collection box 17 is slidably connected to the bottom end of the box body 1. Specifically, the pulley 9 is a fixed pulley, and the cable 8 in the cable reel 10 passes through the wire passing hole 101 and the pulley 9 in sequence and then is connected to the lifting block 7. The cable 8 is in a taut state when the flipping frame 15 does not rotate. When the cable reel 10 winds up the cable, the lifting block 7 rises under the pulling force of the cable 8, and when the cable reel 10 pays out the cable, the lifting block 7 descends under the gravity of the bearing frame 4 and the crushing box 5 itself. A slideway 102 is provided at the bottom inside the box body 1 corresponding to the position of the collection box 17. Specifically, a plurality of rollers are provided at intervals along the sliding direction of the collection box 17 on the slideway 102 to reduce the sliding resistance of the collection box 17 and facilitate the extraction of the collection box 17 from the box body 1 after it is full of water outlets.

[0048] Embodiment 2

[0049] A laser cutting robot capable of recycling water outlets, as shown in Figures 1-11As shown, on the basis of the first embodiment, the difference from the first embodiment is that a crushing box 5 that moves up and down synchronously with the carrier 4 is rotatably connected between the mounting columns 2 on both sides of the box body 1. A collection box 17 is slidably connected to the bottom end of the box body 1. A crushing assembly for crushing the sprue is movably connected to the bottom surface of the crushing box 5 within the collection box 17. Cavities for accommodating the crushing structure within the crushing box are provided on both sides of the box body 1 to prevent the crushing structure of the crushing box 5 from being blocked by the inner wall of the box body 1. Specifically, large pieces of sprue are generally long and brittle. After the long sprue is stacked within the collection box 17, it is easily broken into small pieces by the impact of the crushing assembly. The crushing structure provided on the bottom surface of the crushing box 5 is used to crush the large pieces of sprue that fall into the collection box 17 into small pieces, which helps prevent the large pieces of sprue from cross-stacking within the collection box and reducing the capacity of the collection box 17, enabling the collection box 17 to better collect the sprue and also enabling the sprue to be better dispersed within the collection box 17.

[0050] Please refer to Figures 6-7 、 Figures 8-9 , both ends of the rotating shaft of the crushing box 5 are rotatably connected to a connecting rod 6, and the other end of the connecting rod 6 is rotatably connected to the rotating shaft of the upper carrier 4. Between the mounting columns 2 at both ends of the box body 1, a crushing box slide rail 204 for the end of the crushing box 5 away from the rotating shaft to slide is connected. Through the connecting rod 6 structure, the crushing box 5 can move synchronously with the carrier 4. Specifically, between the mounting columns 2 at both ends of the box body 1, a crushing box slide rail 204 for the end of the crushing box 5 away from its own rotating shaft to slide is connected. One end of the crushing box 5 away from its own rotating shaft is rotatably connected to a roller that contacts the crushing box slide rail 204.

[0051] Please refer to Figures 6-7 、 Figures 10-11, a slide rail 501 is arranged along the length direction in the middle of the bottom surface of the crushing box 5. A slider 19 is slidably connected in the slide rail 501. A driving rod 502 parallel to the slide rail 501 is rotatably connected between the slide rails 501. The driving rod 502 is used to drive the slider 19 to slide, and one end of it is connected with a second driving motor 18. Specifically, the second driving motor 18 drives the slider 19 to reciprocate in the slide rail 501 by means of periodically changing the rotation direction. The bottom end of the slider 19 is rotatably connected with a gear 20. The gear 20 meshes with a rack 503. The rack 503 is fixedly connected in the crushing box 5 and is parallel to the slide rail 501. The bottom end of the gear 20 is fixedly connected with a third driving motor 21. The axis of the third driving motor 21 is inclined to the axis of the gear 20, and a cutter head 22 is connected to the output end. Specifically, the rotation speed of the third driving motor 21 driving the cutter head 22 to rotate is not higher than 300 revolutions per minute. To achieve the purpose of crushing large-sized nozzle gates and avoid causing excessive vibration, the cutter head 22 does not contact the crushing box 5 and the collection box 17. Driven by the driving rod 502 in the crushing box 5, the slider 19 slides along the slide rail 501. Since the gear 20 meshes with the rack 503, the gear 20 keeps rotating during the sliding process of the slider 19. The third driving motor 21 obliquely connected below the gear 20 drives the cutter head 22 to rotate. During the reciprocating movement of the slider 19 in the crushing box 5, the large-sized nozzle gates in the collection box 17 can be effectively crushed. To prevent the cutter head 22 from hitting the inner wall of the crushing box 5 during the sliding process of the slider 19, limit blocks 504 are arranged at both ends of the slide rail 501 in the crushing box 5. The limit blocks 504 are used to limit the slider 19 from approaching the ends of the slide rail 501.

[0052] Embodiment 3

[0053] A laser cutting robot capable of recycling nozzle gates, as Figures 1-11 shown. On the basis of Embodiment 2, the difference from Embodiment 2 is that a baffle 16 inclined to the top surface of the crushing box 5 is rotatably connected in the box body 1. When laser cutting a workpiece, some small nozzle gates on the workpiece will directly fall through the gaps on the bearing frame 4 and be blocked by the baffle 16 on the surface of the crushing box 5. When the bearing frame 4 and the crushing box are turned over, they will be poured into the collection box 17. A small part of the nozzle gates after the cutting surface melts fall on the surface of the crushing box 5 and may adhere to the surface of the crushing box 5. The baffle 16 can scrape the surface of the crushing box 5 when the crushing box 5 rotates, and then scrape the nozzle gates adhered to the surface of the crushing box 5 into the collection box 17. The bottom surface of the baffle 16 is in contact with the top surface of the crushing box 5. The baffle 16 plays a role in blocking small nozzle gates from falling into both sides inside the box body 1, and can also scrape the top surface of the crushing box 5 when the crushing box 5 rotates.

[0054] The working principle of the present invention is as follows: Place the workpiece with the nozzle to be cut on the turning frame 15. The suction component of the turning frame 15 sucks the workpiece. The first driving motor 13 operates, and through the transmission of the gearbox 12, the turning frame 15 is turned above the carrier 4. After the suction component releases the workpiece, the turning frame 15 rotates back to its original position. After the laser cutting robotic arm 3 finishes cutting the nozzle on the workpiece, the first driving motor 13 drives the turning frame 15 to rotate above the workpiece again to suck the workpiece. During the above process, the electromagnetic clutch 11 is in the disconnected state. Then the electromagnetic clutch 11 engages. When the turning frame 15 sucks the workpiece and returns to leave above the carrier 4, the first driving motor 13 drives the wire reel 10 to wind up the cable 8 through the transmission structure, lifting the lifting block 7, and further causing the rotating shafts of the carrier 4 and the crushing box 5 to slide upward in the first guide rail 201 and the second guide rail 202 respectively. The ends of the carrier 4 and the crushing box 5 away from their own rotating shafts slide in the carrier slide rail 203 and the crushing box slide rail 204 respectively, pouring the nozzles on the surfaces of the carrier 4 and the crushing box 5 into the collection box 17. After the turning frame 15 turns to contact the support frame 14, the worker can remove the cut workpiece on the turning frame 15 and replace it with the workpiece to be cut. After the turning frame 15 is replaced with the workpiece to be cut, the first driving motor 13 operates to turn the turning frame 15 into the box body 1. During this process, the wire reel 10 rotates in reverse to release the cable 8, and the carrier 4 and the crushing box 5 slide back to their original positions under their own gravity. When the carrier 4 and the crushing box 5 are reset, the turning frame 15 places the workpiece to be cut on the carrier 4. In this way, the high-efficiency cutting of the workpiece nozzle is realized, and at the same time, large pieces of nozzles can be recycled.

[0055] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations to the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
