Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically a robotic intelligent sorting laser cutting unit. Background Technology

[0002] Robotic intelligent sorting laser cutting is an automated production process that combines robotic intelligent sorting technology with laser cutting technology. It is widely used in industries such as sheet metal processing. The core is to use robots to achieve intelligent sorting of workpieces after cutting, and to complete the entire "cutting-sorting" process with laser cutting equipment.

[0003] Currently, the main functions of intelligent sorting and cutting equipment include physical components such as gripping, laser cutting, conveying equipment, and protective fences. Through the cooperation of these components, metal or non-metal sheets of different shapes and sizes can be cut and transported.

[0004] However, in existing technologies, when transferring flat metal or non-metal sheets, pneumatic or electric parallel grippers are used, along with replaceable flexible pads (such as silicone or polyurethane pads). By adjusting the opening and closing width of the grippers, they can accommodate regular workpieces of different sizes. The pads can increase friction, preventing workpiece slippage and protecting the workpiece surface from damage. However, when gripping irregularly shaped metal or non-metal sheets (with curved or arc-shaped surfaces or edges), the contact area between the pneumatic or electric parallel grippers and the edges of the sheet is significantly reduced. This causes the irregularly shaped metal or non-metal sheets to wobble or tilt during transfer due to uneven force at both ends. Consequently, the irregularly shaped metal or non-metal sheets cannot be accurately transferred to the laser cutting platform, leading to potential cutting position deviations during subsequent cutting and reducing the accuracy of cutting irregularly shaped metal or non-metal sheets.

[0005] To this end, the present invention provides a robotic intelligent sorting laser cutting unit. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the robot intelligent sorting laser cutting unit of the present invention includes a robotic arm, a transfer plate is detachably installed at the free end of the robotic arm, and a transfer component is provided at one end of the transfer plate. The transfer component can grasp the ends of plates of different sizes and realize the smooth transfer of plates of different shapes.

[0008] An adjusting component is located inside the transfer plate. The contact area and degree of fit between the end of the transfer component and the end of the plate can be controlled by the adjusting component.

[0009] The transfer component includes a synchronous belt and telescopic plates. The synchronous belt drive is installed in the inner cavity of the transfer plate, and multiple telescopic plates are fixedly installed along one side of the synchronous belt in a straight line. A U-shaped plate is fixedly installed at one end of each of the multiple telescopic plates, and an electromagnet block is rotatably installed in the inner cavity of each of the multiple U-shaped plates through a reset torsion spring.

[0010] A power-conducting guide rail is fixedly installed on the inner wall of the transfer plate away from its own opening end, and a power-conducting block for energizing the electromagnet block is fixedly installed on one side of the fixed end of multiple telescopic plates.

[0011] Each of the multiple electromagnet blocks has an elastic sheet fixedly installed at one end, and the multiple elastic sheets are bent.

[0012] The transfer device also includes a fixed tube and a sliding tube. Multiple mounting holes are distributed along a straight line on the other side of the synchronous belt. A fixed tube is fixedly installed in the inner cavity of each mounting hole. A sliding tube is slidably installed at the end of each fixed tube away from the mounting hole. A corrugated hose is fixedly installed in the inner cavity of each fixed tube. One end of the corrugated hose extends to the outside of the sliding tube. Two upright blocks are fixedly installed at the end of each sliding tube away from the fixed tube with the central axis of the corrugated hose as the center of symmetry. An adsorption head is rotatably installed between the two upright blocks through a transmission torsion spring. One end of the adsorption head is fixedly connected to the end of the corrugated hose that extends to the outside of the sliding tube.

[0013] The outer wall of the fixed tube is fixedly installed with multiple guide tubes in a ring shape. Each guide tube has a sliding plate slidably installed in its inner cavity. The end of each sliding plate extending to the outside of the guide tube is fixedly connected to the outer wall of the sliding tube. Each guide tube has a top pressure spring fixedly installed on its inner wall away from its opening end, which is connected to the other end of the sliding plate.

[0014] Multiple corrugated hoses are fixedly installed with return springs in a ring-shaped distribution on their outer walls. One end of each return spring is fixedly connected to the inner wall of the fixed tube. A vent head is fixedly installed at one end of each corrugated hose located in the inner cavity of the fixed tube.

[0015] A horizontal plate is fixedly installed inside the synchronous belt, and multiple air supply pipes are fixedly installed at the bottom of the horizontal plate. A ring electromagnet for attracting the air supply head is fixedly installed in the inner cavity of each air supply pipe.

[0016] The adjusting components include sleeves and sliding rods. Multiple sleeves are fixedly installed in the inner cavity of the transfer plate. Sliding rods are slidably connected to the inner cavities of the multiple sleeves. A U-shaped pressure plate is fixedly installed at one end of the multiple sliding rods. Support springs connected to the inner walls of the sleeves are fixedly sleeved on the outer walls of the multiple sliding rods. Two downward pressure blocks are symmetrically fixedly installed on the outer walls of the moving end of the telescopic plate and the outer walls of the sliding tubes.

[0017] A hydraulic cylinder is fixedly installed on the inner wall of the transfer plate away from its own opening end. A bracket is fixedly installed on the power output end of the hydraulic cylinder. Multiple connecting pipes are fixedly installed on both ends of the bracket. A top pressure column is slidably installed in the inner cavity of each of the multiple connecting pipes, and a telescopic spring connected to one end of the top pressure column is fixedly installed in the inner cavity of each of the multiple connecting pipes.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The transfer device can change the adsorption method of the sheet material according to the material type, thereby adsorbing and transferring flat metal or non-metal sheets, avoiding shaking of metal sheets during handling, and improving the accuracy of cutting flat metal sheets.

[0020] 2. By continuously pressing the small end of the telescopic plate and the outside of the sliding tube with the adjusting component, the small end of the telescopic plate and the sliding tube continue to move downward until multiple rubber hoses or multiple elastic plates are tightly attached to the top of the irregular metal or non-metal plate. This prevents some rubber hoses or elastic plates from being suspended in the air, and avoids the irregular metal or non-metal plate from shaking or falling during transfer, thus improving the accuracy of cutting irregular metal or non-metal plates.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figure 1-11 As shown, this embodiment of the invention includes a robotic arm 1, with a transfer plate 2 detachably mounted on the free end of the robotic arm 1. An industrial camera is fixedly mounted on the outer wall of the robotic arm 1. Through visual algorithms (such as edge detection and contour matching), key features of the workpiece are extracted from the processed image, including the outline shape of the workpiece (such as rectangle, circle, irregular shape) and feature points (such as corners and hole positions). The features are then compared with a preset "workpiece feature template" in the system to confirm the type of the object.

[0037] The intelligent sorting laser cutting unit mainly includes a laser cutting machine, a robotic arm 1, and an industrial camera. The laser cutting machine melts or vaporizes the sheet material with a high-energy laser beam and cuts it according to a preset graphic (such as the shape of the part designed in CAD), achieving high-precision processing of complex contours (such as irregular holes and curved edges), with a cutting accuracy of ±0.1mm.

[0038] The robotic arm 1 can grasp and transport finished products. Its end effector (such as a pneumatic gripper or vacuum suction cup) picks up finished workpieces before and after cutting, and transports them to designated areas (such as palletizing tables or conveyor belts) along a preset path, avoiding workpiece damage caused by manual contact. Figure 1 (As shown).

[0039] An industrial camera can capture the original position of the sheet metal, transmit the coordinate data to the laser cutting equipment, correct the sheet metal placement deviation, ensure that the cutting pattern matches the sheet metal position, avoid cutting misalignment, and at the same time compare the actual image of the workpiece with the preset standard template to identify cutting defects (such as burrs, incomplete cuts), screen out unqualified workpieces, and prevent them from flowing into subsequent processes.

[0040] Synchronous belts 4 are rotatably installed in the inner cavity of transfer plate 2. Two synchronous belts 4 are rotatably installed in the inner cavity of transfer plate 2. The drive rollers of the two synchronous belts 4 are connected by a drive rod. With the cooperation of the drive rod, the two synchronous belts 4 can rotate synchronously. At the same time, a locking motor is fixedly installed on the outer wall of transfer plate 2. The power output end of the locking motor extends into the inner cavity of transfer plate 2 and is fixedly connected to one end of the drive roller of one of the synchronous belts 4. The self-locking motor can provide power for the rotation of synchronous belts 4 and lock the synchronous belts 4 after they have rotated.

[0041] The locking motor uses a miniature DC motor (such as a permanent magnet DC motor) as its power source. After being powered on, the motor reduces its speed and increases its torque through a gear reduction mechanism, which then drives the cam, lead screw, or rack to move. For example, the rotation of the cam pushes the bolt out to lock, while the reverse rotation pulls the bolt back to unlock.

[0042] Multiple telescopic plates 6 are fixedly installed along a straight line on one side of the synchronous belt 4. A U-shaped plate 3 is fixedly installed at one end of each telescopic plate 6. An electromagnet block 8 is rotatably installed within the inner cavity of each U-shaped plate 3 via a return torsion spring. Each telescopic plate 6 is mainly composed of two metal sliding plates of different sizes, one of which is larger than the other. A sliding groove is opened at one end of the larger metal sliding plate, and the smaller metal sliding plate slides within the inner cavity of the sliding groove. A compression spring is fixedly installed on the inner wall of the sliding groove away from its opening end, and one end of the compression spring is connected to one end of the smaller metal sliding plate (e.g., ...). Figure 9 As shown, the smaller metal slide plate is fixedly connected to the side away from the sliding groove and the side of the timing belt 4. One end of the U-shaped plate 3 is fixedly connected to one end of the smaller metal slide plate. With the cooperation of the two metal slide plates of different sizes, the U-shaped plate 3 can move, thereby changing the distance between the U-shaped plate 3 and the timing belt 4.

[0043] When the U-shaped plate 3 is pressed and moved closer to the synchronous belt 4, the compression spring is compressed. After the pressing force on the U-shaped plate 3 is released, the compression spring converts the elastic potential energy into the kinetic energy for the U-shaped plate 3 to reset, thus realizing the rapid reset of the U-shaped plate 3.

[0044] A power-conducting guide rail 9 is fixedly installed on the inner wall of the transfer plate 2 away from its own opening end. A power-conducting block 26 for energizing the electromagnet block 8 is fixedly installed on one side of the fixed end of the multiple telescopic plates 6. One end of the power-conducting block 26 is fixedly connected to the outer wall of the large end of the telescopic plate 6. At the same time, the telescopic plate 6 and the U-shaped plate 3 are both made of alloy material. When the power-conducting block 26 is energized, the current is transmitted to the electromagnet block 8 along the telescopic plate 6 and the U-shaped plate 3.

[0045] Multiple electromagnet blocks 8 are each fixedly fitted with an elastic sheet 27 at one end. The elastic sheets 27 are all bent. When the robotic arm 1 is used to move the metal plate, firstly, the locking motor is started, causing the two synchronous belts 4 to rotate until the multiple telescopic plates 6 installed on one side of the two synchronous belts 4 are directly below the synchronous belts 4. Then, the locking motor is turned off to position the rotated synchronous belts 4. Next, the free end of the robotic arm 1 is moved directly above the metal plate, and the bent outer walls of the multiple elastic sheets 27 simultaneously contact the ends of the metal plate until the bent outer walls of the elastic sheets 27 are completely deformed and contact the metal plate. The end faces of the metal sheet are attached, and multiple energized conductive blocks 26 installed on one side of the large end of multiple telescopic plates 6 are inserted into the inner cavity of the energized guide rail 9. Then, the energized guide rail 9 is energized, which enables multiple electromagnet blocks 8 to provide a large attraction force to the metal sheet, thus realizing the connection between the electromagnet blocks 8 and the metal sheet. When the free end of the robotic arm 1 moves, the metal sheet moves accordingly, thereby accurately transporting the metal sheet to the designated position, while avoiding the metal sheet from shaking during the transportation process, thus improving the accuracy of cutting flat metal sheets.

[0046] Multiple mounting holes are provided along a straight line on the other side of the synchronous belt 4. A fixing tube 16 is fixedly installed in the inner cavity of each mounting hole. One end of the fixing tube 16 is inserted into the inner cavity of the mounting hole, and the outer wall of the fixing tube 16 is fixedly connected to the inner wall of the mounting hole. The insertion end of the fixing tube 16 is flush with the end face of the synchronous belt 4 to avoid the fixing tube 16 affecting the normal rotation of the drive roller.

[0047] Multiple fixed tubes 16 have sliding tubes 12 slidably installed at the ends away from the mounting holes. Multiple guide tubes 14 are fixedly installed in a ring on the outer wall of the fixed tubes 16. Sliding plates 13 are slidably installed in the inner cavities of the multiple guide tubes 14. The ends of the multiple sliding plates 13 extending to the outside of the guide tubes 14 are fixedly connected to the outer wall of the sliding tubes 12. The inner walls of the multiple guide tubes 14 away from their opening ends are fixedly installed with top pressure springs 15 connected to the other end of the sliding plates 13. Among them, two sliding tubes 12 are fixedly installed in a ring on the outer wall of the fixed tubes 16. Sliding plates 13 are slidably installed in the inner cavities of the two sliding tubes 12. With the cooperation of the two sliding tubes 12 and the two sliding plates 13, the fixed tubes 16 and the sliding tubes 12 can be slidably connected. At the same time, under the action of the top pressure springs 15, the bottom of the sliding tubes 12 and the top of the fixed tubes 16 can be made to fit together in real time.

[0048] Corrugated hoses 30 are fixedly installed in the inner cavities of multiple fixed tubes 16. One end of the corrugated hose 30 extends to the outside of the sliding tube 12. Two upright blocks 11 are fixedly installed at the ends of multiple sliding tubes 12 away from the fixed tubes 16, with the central axis of the corrugated hose 30 as the center of symmetry. An adsorption head 10 is rotatably installed between the two upright blocks 11 through a transmission torsion spring. One end of the adsorption head 10 is fixedly connected to the end of the corrugated hose 30 that extends to the outside of the sliding tube 12. When it is necessary to transfer non-metallic plates, the locking motor is started again, so that the multiple fixed tubes 16 rotate with the synchronous belt 4 to the position directly below the synchronous belt 4, and then the locking motor is turned off.

[0049] Multiple corrugated hoses 30 are fixedly installed with return springs 17 in a ring on their outer walls. One end of each return spring 17 is fixedly connected to the inner wall of the fixed tube 16. The return springs 17 can continuously provide upward tension to the corrugated hoses 30, so that the corrugated hoses 30 located in the inner cavity of the fixed tube 16 are completely located in the inner cavity of the fixed tube 16, preventing the part of the corrugated hoses 30 located in the inner cavity of the fixed tube 16 from extending to the outside of the fixed tube 16 and affecting the normal rotation of the synchronous belt 4.

[0050] Multiple corrugated hoses 30 are fixedly installed with vent heads 18 at one end of the inner cavity of the fixed tube 16. A horizontal plate 5 is fixedly installed inside the synchronous belt 4. Multiple air supply pipes 29 are fixedly installed at the bottom of the horizontal plate 5. A ring electromagnet 7 for attracting the vent heads 18 is fixedly installed in the inner cavity of each air supply pipe 29. The vent heads 18 are made of stainless steel and their diameter is smaller than that of the air supply pipes 29. When the multiple fixed tubes 16 rotate to the position directly below the synchronous belt 4, the central axis of the multiple vent heads 18 coincides with the central axis of the multiple air supply pipes 29. Then, the locking motor can be turned off to stop the synchronous belt 4 from rotating. Then, the ring electromagnet 7 is energized. Under the attraction of the ring electromagnet 7, the multiple vent heads 18 are inserted into the inner cavities of the multiple air supply pipes 29 until the end of the vent head 18 away from the corrugated hose 30 is in contact with the bottom of the ring electromagnet 7. This achieves mutual communication between the inner cavities of the vent heads 18 and the air supply pipes 29.

[0051] The multiple gas supply pipes 29 are connected by a conduit, which allows the multiple gas supply pipes 29 to communicate with each other. A connecting pipe that communicates with the inner cavity of the conduit is fixedly installed on the outer wall of the conduit. The free end of the connecting pipe extends to the outside of the transfer plate 2 and is connected to the vacuum equipment (this is existing technology and will not be described in detail here).

[0052] When transferring non-metallic flat sheets, the robotic arm 1 rotates the transfer plate 2 to directly above the non-metallic flat sheet, and then moves the transfer plate 2 down until the multiple suction heads 10 are completely in contact with the top of the non-metallic flat sheet. Then, the vacuum equipment is activated to quickly extract the air from the multiple suction heads 10, which provides a strong attraction to the non-metallic flat sheet and connects it with the multiple suction heads 10. After the robotic arm 1 transfers the non-metallic flat sheet to the cutting position, the vacuum equipment is turned off, which detaches the non-metallic flat sheet from the suction heads 10. This allows the non-metallic flat sheet to be accurately transported to the designated position, while avoiding shaking of the non-metallic flat sheet during transportation, thus improving the accuracy of cutting the non-metallic flat sheet.

[0053] A rubber hose is fixedly sleeved at the end of the adsorption head 10 away from the corrugated hose 30. The rubber hose is designed as a frustum-shaped structure. The small end of the rubber hose is sleeved on the end of the adsorption head 10. When the adsorption head 10 adsorbs the non-metallic flat plate, the large end of the rubber hose is in close contact with the top of the non-metallic flat plate. This can improve the tightness of the contact between the adsorption head 10 and the surface of the non-metallic flat plate, and prevent external air from entering the interior of the adsorption head 10 through the contact end between the adsorption head 10 and the non-metallic flat plate, which would cause the non-metallic flat plate to fall off during transfer.

[0054] The synchronous belt 4, telescopic plate 6, electromagnet block 8, elastic sheet 27, adsorption head 10, sliding tube 12, fixed tube 16, corrugated hose 30 and annular electromagnet 7 constitute the transfer component. The transfer component can change the adsorption method of the plate according to the material type of the plate, thereby adsorbing and transferring flat metal or non-metal plates, avoiding shaking of metal plates during transportation, and improving the accuracy of cutting flat metal plates.

[0055] Based on the applicant's understanding of the prior art, when transferring irregularly shaped metal or non-metal plates (such as corrugated plates), due to the different distances between the multiple adsorption heads 10 and the multiple electromagnet blocks 8 and the top of the irregular metal or non-metal plate, some adsorption heads 10 and electromagnet blocks 8 cannot contact the top of the irregular metal or non-metal plate, which causes the irregular metal or non-metal plate to fall off due to gravity during the transfer, thereby affecting the normal transfer of the irregular metal or non-metal plate.

[0056] To solve the above-mentioned technical problems, multiple sleeves 31 are fixedly installed in the inner cavity of the transfer plate 2. Each sleeve 31 has a sliding rod 24 slidably connected to its inner cavity. A U-shaped pressure plate 20 is fixedly installed at one end of each sliding rod 24, and a support spring 25 connected to the inner wall of the sleeve 31 is fixedly sleeved on the outer wall of each sliding rod 24. Two downward pressure blocks 28 are symmetrically fixedly installed on the outer wall of the moving end of the telescopic plate 6 and the outer wall of the sliding tube 12. When the telescopic plate 6 or the fixed tube 16 is transferred to directly below the synchronous belt 4, the downward pressure block 28 is located under the U-shaped pressure plate. Directly below the plate 20, the tops of multiple sliding rods 24 are pressed simultaneously, causing the bottoms of multiple U-shaped pressure plates 20 to fit against the tops of the lower pressure block 28. As the multiple sliding rods 24 continue to move downward, the small end of the telescopic plate 6 and the sliding tube 12 continue to move downward. At the same time, the downward distance of the sliding rods 24 at different positions is adjusted according to the distance between the multiple adsorption heads 10 and the multiple electromagnet blocks 8 and the top of the irregular metal or non-metal plate, until the multiple rubber hoses or multiple elastic sheets 27 are tightly fitted against the top of the irregular metal or non-metal plate.

[0057] Because the electromagnet block 8 and the U-shaped plate 3 are rotatably connected by a reset torsion spring, and the suction head 10 and the outer walls of the two upright blocks 11 are rotatably connected by a transmission torsion spring, the electromagnet block 8 of the suction head 10 changes its angle according to the shape of the irregular metal or non-metal plate, so that the rubber hose and elastic sheet 27 are tightly attached to the end face of the irregular metal or non-metal plate, avoiding the state of some rubber hose or elastic sheet 27 being suspended, and preventing the irregular metal or non-metal plate from shaking or falling during transfer, thus improving the accuracy of cutting irregular metal or non-metal plates.

[0058] A hydraulic cylinder is fixedly installed on the inner wall of the transfer plate 2 away from its own opening end. A bracket 19 is fixedly installed on the power output end of the hydraulic cylinder. Multiple connecting pipes 21 are fixedly installed on both ends of the bracket 19. A top pressure column 23 is slidably installed in the inner cavity of each of the multiple connecting pipes 21. A telescopic spring 22 connected to one end of the top pressure column 23 is fixedly installed in the inner cavity of each of the multiple connecting pipes 21. When the telescopic plate 6 or the fixed pipe 16 is transferred to the direct under end of the synchronous belt 4, the hydraulic cylinder is activated, causing the bracket 19 to move down together with the power output end of the hydraulic cylinder until the bottom of the multiple top pressure columns 23 simultaneously contacts the top of the multiple sliding rods 24. As the bracket 19 continues to move down, the top pressure columns 23 continuously press the top of the sliding rods 24, while the telescopic spring 22 is continuously compressed. Because the distances of the multiple rubber hoses and multiple elastic plates 27 from the end face of the irregular metal or non-metal plate are different, the degree of compression of the telescopic spring 22 is different until the multiple rubber hoses and multiple elastic plates 27 are in complete contact with the end face of the irregular metal or non-metal plate.

[0059] The sleeve 31, slide bar 24, bracket 19, hydraulic cylinder, U-shaped pressure plate 20, and lower pressure block 28 constitute the adjusting component. The adjusting component continuously presses the small end of the telescopic plate 6 and the outside of the sliding tube 12, causing the small end of the telescopic plate 6 and the sliding tube 12 to move downward until multiple rubber hoses or multiple elastic plates 27 are tightly attached to the top of the irregular metal or non-metal plate. This prevents some rubber hoses or elastic plates 27 from being suspended in the air, and prevents the irregular metal or non-metal plate from shaking or falling during transfer, thus improving the accuracy of cutting the irregular metal or non-metal plate.
