[0018] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0019] Refer to the attached instructions Figures 1 - 7 ; Embodiment 1: The first embodiment of the present invention provides a high-precision metal sheet shearing device, which includes a machine body 1 for placement. A rotatable and liftable robot arm 2 is arranged on the top of the machine body 1. The robot arm 2 includes an electric turntable that can rotate 380 degrees, several telescopic rods and steering parts that can be telescoped. The electric turntable can realize the multi-angle rotation of the robot arm 2, several telescopic rods can realize the length adjustment of the robot arm 2, and the steering parts are used to adjust the angles between the telescopic rods; A cutting part 3 for cutting metal is arranged on the robot arm 2, and the cutting part 3 drives the cutting of the metal plate through the robot arm 2; A storage part 4 for storing tools is also provided at the top of the machine body 1; A camera part 5 for analyzing metal materials is provided on the surface of the robotic arm 2. The camera part 5 includes a camera and a drive module that can control the robotic arm 2 through networking. By analyzing the metal plate with the camera, the drive module can be used to control the robotic arm 2 to drive the cutting part 3 to select a suitable tool inside the storage part 4; A placement table 6 for placing uncut metal plates is provided at the front of the machine body 1, and a guiding part 7 for guiding the movement of the metal plate is provided at the rear of the machine body 1. The use of the guiding part 7 eliminates the need for manual handling of the cut metal plates, avoiding the accumulation of cut metal plates from affecting the processing efficiency; Pressing parts 8 for fixing the metal plate are provided at both the front and rear of the machine body 1. The pressing parts 8 at the front and rear positions are mainly used to fix the position of the metal plate during processing, preventing the metal plate from loosening due to manual holding during processing. Manually fixing is more inconvenient when processing thin metal plates, and it is easy to have a position deviation during the shearing process. The use of the pressing part 8 effectively solves this problem; The guiding part 7 includes a placement frame 701 placed behind the machine body 1. A second screw telescopic part 702 for lifting is provided on the back of the machine body 1. The second screw telescopic part 702 has the same structure as the first screw telescopic part 305. A lifting platform 703 is fixedly installed at the middle lifting end of the second screw telescopic part 702. The top of the lifting platform 703 is installed with the pressing part 8 located at the rear of the machine body 1; The pressing part 8 at the rear of the machine body 1 includes a third screw telescopic part 801 fixed on the surface of the lifting platform 703. A shaping frame 802 is provided at the middle lifting end of the third screw telescopic part 801. A driving motor 803 is fixedly installed inside the shaping frame 802. The driving motor 803 is an asynchronous motor. A transmission rod 804 is movably installed in the middle of the driving motor 803, and a number of groups of transmission rods 804 are provided. One end of each group of transmission rods 804 is provided with a driving wheel 805. A transmission belt 806 is movably installed outside the driving wheel 805. A conveyor belt 807 is also installed outside a number of transmission rods 804. A number of anti-slip pads 808 are provided on the surface of the conveyor belt 807. The anti-slip pads 808 are made of rubber material; The staff places the metal plate to be processed on the placement table 6, and then activates the pressing part 8 at the front of the machine body 1 on the placement table 6. At this time, the third screw telescopic part 801 on the front pressing part 8 is activated, and the third screw telescopic part 801 drives the shaping frame 802 to move up and down. The specific movement needs to be based on the thickness of the selected processed metal plate. When the anti-slip pad 808 on the conveyor belt 807 contacts the surface of the metal plate, the extrusion fixation of the metal plate can be achieved; To ensure the stability of the metal plate fixation, the pressing part 8 at the rear of the body 1 is started simultaneously. The pressing part 8 at the rear then fixes the metal plate at the rear, so that the front and rear positions of the metal plate are reinforced by the two pressing parts 8. At this time, the effective fixation of the metal plate is achieved, and the overall fixation effect is good; When the metal plate is placed on the placement table 6, the imaging part 5 on the robotic arm 2 synchronously observes the metal plate. The gloss, texture, oxidation traces and other characteristics of the metal surface are captured by a high-resolution camera (such as a 4K macro lens), and compared with the cloud material database. Then, it is connected to the network and combined with AI to conduct a comparative analysis of the metal plate. Subsequently, according to the analysis results, the robotic arm 2 is driven. At this time, the robotic arm 2 drives the cutting part 3 to move to the storage part 4 through position adjustment to select different tools for different cutting tools, so that different metal plates can be cut according to different materials. At this time, it can avoid high wear of different cutting tools when cutting different metal plates, so as to ensure the service life of the cutting tools and reduce the economic losses of users.

[0020] Embodiment 2: The cutting part 3 includes an assembly plate 301 fixed at one end of the robotic arm 2. A raised block 302 is fixedly installed on the surface of the assembly plate 301. A first magnet block 303 is embedded on the surface of the raised block 302. Two push rod motors 304 are arranged on the surface of the assembly plate 301 outside the raised block 302. A first screw telescopic member 305 is arranged at the output end of each of the two push rod motors 304. A clamping plate 306 is fixedly installed at the moving end of each of the two first screw telescopic members 305. The first screw telescopic member 305 includes a box body, a limiting groove opened on the box body, an adjusting motor, a screw rod, and a moving block installed on the screw rod. Starting the adjusting motor can drive the screw rod to rotate. The adjusting motor is selected as an asynchronous motor, and the screw rod cooperates with the limiting groove to drive the moving block to move horizontally; The storage part 4 includes a retaining box 401. A partition plate 402 for dividing the internal space is fixedly installed in the inner cavity of the retaining box 401. The partition plate 402 divides the internal space of the retaining box 401 into several placement bins 403. Several cutting tools 404 of different materials and sizes are placed inside the several placement bins 403. A second magnet block 405 is fixedly installed at the top of each of the several cutting tools 404. The first magnet block 303 and the second magnet block 405 are set with opposite magnetic properties, so as to achieve the effect of attracting each other with opposite sexes. Two relatively arranged closing members 406 are arranged at the top of each placement bin 403. A metal absorption assembly 9 is arranged at the bottom of the retaining box 401; The closure member 406 includes a merging groove 4061 fixed on the surface of the partition board 402 outside the placement bin 403. A positioning rod 4062 is fixedly installed on the inner wall of the merging groove 4061. A cover body 4063 that closes the top of the placement bin 403 is movably installed outside the positioning rod 4062. A positioning spring 4064 is fixedly installed on the surface of the cover body 4063, and one end of the positioning spring 4064 is fixed to the inner wall of the merging groove 4061. The setting of the closure member 406 is mainly used to protect the shearing knife 404 and prevent the shearing knife 404 from being corroded and damaged due to long-term exposure to the air. When the cutting part 3 on the robotic arm 2 determines the appropriate tool, the robotic arm 2 will drive the cutting part 3 to move towards the top of the corresponding placement bin 403 on the storage part 4. At this time, the raised block 302 on the cutting part 3 will squeeze the cover body 4063 on the closure member 406. The squeezed cover body 4063 will rotate towards the inside of the merging groove 4061 under the position limitation of the positioning rod 4062. Subsequently, the rotating cover body 4063 will also stretch the positioning spring 4064. At this time, the placement bin 403 on the retention box 401 is in an open state. When the raised block 302 is inserted into the inside of the placement bin 403, the first magnet block 303 can be magnetically fixed to the second magnet block 405 on the shearing knife 404. Then, start the robotic arm 2 to drive the cutting part 3 to lift, so that the shearing knife 404 can be automatically taken out of the placement bin 403. After taking out the shearing knife 404, start the push rod motor 304 to drive the first lead screw telescopic member 305 to move downward. At this time, the clamping plate 306 on the first lead screw telescopic member 305 moves synchronously, and the clamping plate 306 adjusts the corresponding position according to the thickness of the shearing knife 404. In this way, the shearing knife 404 can be clamped and fixed by the clamping plate 306, and the whole operation method is simple and convenient. After the position of the shearing knife 404 is fixed, the robotic arm 2 can be used to drive the cutting part 3 to realize the shearing work of the shearing knife 404 on the metal plate. At the same time, because the robotic arm 2 has a flexible position adjustment function, the cutting of the curve and various complex shapes on the surface of the metal plate can be completed. The whole cutting range is wide, the cutting effect is good, and the inconvenience caused by subsequent processing is also avoided.

[0021] Embodiment 3: The metal absorption assembly 9 includes an assembly groove 901 opened on the surface of the retention box 401. The inner cavity of the assembly groove 901 communicates with the inner cavities of a plurality of placement bins 403. A plurality of support rods 902 are fixedly installed at the bottoms of the inner cavities of the plurality of placement bins 403. A storage box 903 is slidably installed in the inner cavity of the assembly groove 901. A third magnet block 904 is fixedly installed at the bottom of the inner cavity of the storage box 903. The setting of the metal absorption assembly 9 is mainly used for the convenient collection of metal debris. The pressing part 8 at the rear of the machine body 1 has the same structure as the pressing part 8 at the front of the machine body 1. The corresponding third screw rod telescopic member 801 on the pressing part 8 at the front of the machine body 1 is fixed on the surface of the placement table 6, and the third screw rod telescopic member 801 has the same structure as the second screw rod telescopic member 702 and the first screw rod telescopic member 305; After the shearing blade 404 finishes cutting the metal plate, the two pressing parts 8 can be started synchronously. At this time, the drive motor 803 on the pressing part 8 is powered on and started. At this time, the drive motor 803 drives the transmission rod 804 to rotate. The rotating transmission rod 804 drives a plurality of transmission rods 804 to rotate synchronously through the transmission wheel 805 and the transmission belt 806. Subsequently, the transmission rod 804 can drive the conveyor belt 807 and the anti-slip pad 808 to transport the processed metal plate. Finally, the processed metal plate can be moved to the lifting table 703 on the guiding part 7 under the push of the two pressing parts 8. In this way, the lifting table 703 can also perform corresponding height adjustment in cooperation with the second screw rod telescopic member 702, and then cooperate with the pressing part 8 at the rear of the machine body 1 on the lifting table 703 to transport the metal plate into the placement frame 701 for stacking. In this way, the processed metal plates can be neatly placed, avoiding the situation that the traditional processed metal plates directly slide to the ground, and at the same time preventing the situation that some thin metal plates are deformed due to extrusion when contacting the ground. It facilitates the subsequent placement work of the processed metal plates, and at the same time avoids the subsequent cutting work being affected by the messy placement of the processed metal plates, and the cutting efficiency is further improved.

[0022] Embodiment 4: A dust suction port 10 is opened on the surface of the machine body 1, a dust suction chamber 11 is opened on one side of the machine body 1, and a guiding hole 12 is also opened on the side surface of the machine body 1. A guiding rod 13 is movably installed in the inner cavity of the guiding hole 12. One end of the guiding rod 13 is fixedly installed with a blower 14. An isolation net 15 is fixedly installed at the suction end of the blower 14. The isolation net 15 is used to protect the inside of the blower 14 to prevent metal debris from entering the inside of the blower 14 and causing damage. A sealing ring 16 is fixedly installed outside the isolation net 15 at the suction end of the blower 14. The surface of the sealing ring 16 is fitted with the surface of the dust suction chamber 11, so as to avoid the ineffective fitting between the blower 14 and the surface of the machine body 1; During the shearing process of the metal plate, the fan 14 can be started synchronously. The fan 14 uses the suction end to generate suction inside the dust collection bin 11, and the dust collection bin 11 is connected to the dust collection port 10. In this way, when the fan 14 is running, the dust collection port 10 can be used to collect metal debris on the top of the body 1, and the collected metal debris will fall into the dust collection bin 11, and the fan 14 cooperates with the isolation net 15 to block the metal debris. At regular intervals, the fan 14 can be pulled, and the fan 14 is stably moved along the position of the guide hole 12 by the guide rod 13, thereby avoiding inaccurate position movement of the fan 14 in the later stage. As the fan 14 moves, the surface of the sealing ring 16 on the suction end is separated from the opening of the dust collection bin 11 on the side of the body 1, so that the metal debris can be exported, thereby realizing convenient processing of the metal debris.

[0023] Embodiment 5: After the cutting of the metal plate is completed, the robot arm 2 can be started to drive the cutting unit 3 to move to the top of the retaining box 401 of the storage unit 4 again. The specific position is determined by taking out the placement bin 403 on the corresponding shearing knife 404. Then the robot arm 2 drives the cutting unit 3 to squeeze the closing member 406 again. At this time, it is the shearing knife 404 that squeezes the closing member 406. As the surface of the shearing knife 404 contacts the outer wall of the cover 4063 on the closing member 406, the outer wall of the cover 4063 can be used to scrape the surface of the shearing knife 404. After the scraping, the shearing knife 404 The debris with strong surface viscosity can be scraped off, and the scraped debris will also be introduced into the placement bin 403. When the closing member 406 on the placement bin 403 is opened, the push rod motor 304 can be started to drive the first screw rod telescopic member 305 to move the clamping plate 306. At this time, the clamping plate 306 can be used to push the shearing knife 404 to separate the second magnet block 405 on the shearing knife 404 from the first magnet block 303 on the protruding block 302. Then the shearing knife 404 will separate from the cutting part 3, so that the shearing knife 404 can be automatically stored inside the placement bin 403. When there are metal debris inside the placement bin 403, the third magnet block 904 inside the storage box 903 on the metal absorption component 9 will produce a magnetic attraction effect on the metal debris, so that all the metal debris inside the placement bin 403 can be introduced into the storage box 903 for centralized collection, thereby realizing automatic cleaning of the shear knife 404, and the entire cleaning process does not require power drive. At the same time, the stored shear knife 404 can also avoid dangerous factors such as corrosion caused by long-term exposure to the air, thereby further improving the placement safety of the shear knife 404, and the service life of the shear knife 404 is also improved simultaneously.
