Description

Technical Field

[0001] This invention relates to the field of metal sheet processing technology, specifically to an automatic loading and unloading and corner cutting device for stainless steel water tank panels. Background Technology

[0002] Stainless steel water tanks are widely used in water supply, fire protection, and industrial circulating water storage due to their advantages such as corrosion resistance, high strength, and long service life. As the core basic component of water tanks, stainless steel water tank plates require precise cutting of the four corners during processing to eliminate the sharpness of the plate edges and to adapt to the structural size requirements of water tank welding and assembly. Therefore, the cutting of the four corners is a key step in the processing of stainless steel water tank plates.

[0003] Currently, the industry mostly uses traditional semi-automatic processing methods or relies on manual assistance for the corner cutting of stainless steel water tank panels. Specifically, the following technical issues exist: In the loading and unloading stage, existing processing methods generally require manual handling of stainless steel water tank panels to the corner cutting station, followed by manual transfer to the storage area after processing. This process is not only labor-intensive and inefficient, but also prone to surface scratches due to manual handling deviations, potentially posing a safety risk of operator injury from the edges of the panels. In the corner cutting stage, the stamping and cutting structures of existing corner cutting equipment are mostly fixed installation designs. When processing stainless steel water tank panels of different sizes to meet the production needs of water tanks with different capacities, it is necessary to stop the machine to replace the corresponding corner cutting mold or manually disassemble and adjust the installation position of the stamping head. This not only results in long downtime, disrupting the continuity of batch production, but also increases the labor costs of mold replacement and structural adjustments, making it difficult to adapt to diverse and multi-batch processing needs.

[0004] To address these issues, those skilled in the art have proposed an automatic loading and unloading device for stainless steel water tank panels, specifically a four-corner cutting device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic loading and unloading device for stainless steel water tank panels with four corners cut, thus solving the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic loading and unloading and corner cutting device for stainless steel water tank panels, comprising: The frame serves as the supporting carrier for the entire device. A support frame is fixedly installed on the top of the frame, and a support plate for supporting the stainless steel water tank plate is fixedly installed in the middle of the inner side of the frame. An adjustment component, installed at the bottom of the support plate, is used to adjust the position of the angle-cutting stamping structure to accommodate the angle-cutting requirements of stainless steel water tank panels of different sizes. A fixing component is installed on the inner side of the frame and is positioned above the support plate to press and fix the stainless steel water tank plate when it is placed on top of the support plate. The grinding components consist of four parts, each corresponding to one of the four corners of the stainless steel water tank panel. They are used to grind the edges of the stainless steel water tank panel after the corners have been cut to remove burrs. An automatic loading and unloading assembly is installed on the inner side of the support frame. It is used to automatically feed the stainless steel water tank plate to be processed into the equipment to complete the loading, and to automatically transport the stainless steel water tank plate after corner cutting and grinding to the designated position to complete the unloading. A negative pressure dust collection component is installed outside the fixed component and is set in the working area of ​​the polishing component to absorb and collect the dust generated when the polishing component is working.

[0007] Through the above technical solution, the automatic loading and unloading components are supported by the top support frame, and the inner middle support plate carries the plates to be processed, providing a stable foundation for the operation of each component; the adjustment component can flexibly adjust the position of the corner-cutting stamping structure to adapt to the corner-cutting requirements of different sized water tank plates, improving the equipment's versatility; the fixing component can press the water tank plates on the fixed support plate to prevent plate displacement during processing, ensuring the accuracy of corner cutting and grinding; the four grinding components corresponding to the corners of the plates can remove burrs from the edges after corner cutting, improving the surface quality and safety of the product; the automatic loading and unloading component can automatically complete the loading of plates to be processed and the unloading of processed plates without manual intervention, greatly improving processing efficiency; the negative pressure dust collection component can specifically collect the dust generated during grinding, improving the workshop working environment and reducing the impact of dust on equipment operation and personnel health. All components work together to achieve integrated automation of water tank plate processing, effectively solving the problems of low processing efficiency, poor accuracy, high labor intensity, and dust pollution in traditional processing, and reducing enterprise production costs.

[0008] Preferably, the adjustment assembly includes an electric telescopic rod installed inside the frame. The telescopic end of the electric telescopic rod is fixedly connected to a drive rack. The bottom of the support plate is movably connected to a rotating plate via a bearing. The bottom of the rotating plate is fixedly connected to a drive gear. The outer side of the drive gear meshes with the outer side of the drive rack. Multiple hinge rods are rotatably connected to the outer side of the rotating plate. A swing rod is hinged to the end of each hinge rod. Multiple support seats are fixedly connected to the inner side of the frame. The outer side of the swing rod is slidably connected to the upper surface of the support seat. A hydraulic cylinder is installed on one side of the top of the swing rod. A punching head for cutting the corner of the stainless steel water tank plate is installed at the output end of the hydraulic cylinder.

[0009] Through the above technical solution, the electric telescopic rod drives the rack to move, which in turn drives the drive gear and rotating plate that mesh with it to rotate. Then, the hinge rod pulls the swing rod to slide on the support base, so as to realize the flexible adjustment of the position of the hydraulic cylinder and the punch head at the top of the swing rod. Its core function is to accurately adapt to the four-corner cutting requirements of stainless steel water tank plates of different sizes.

[0010] Preferably, the fixing assembly includes electric guide rails installed on the left and right sides inside the frame, an electric slider is installed on the outside of the electric guide rails, a connecting plate is installed on the top of the electric slider, a dual-axis motor is installed on one side of the top of the connecting plate, a connecting shaft is fixedly connected to one of the output ends of the dual-axis motor, two connecting strips are fixedly connected to the outside of the connecting shaft, and a pressing block is rotatably installed on one side of the bottom end of the connecting strip.

[0011] The above technical solution uses electric guide rails on the left and right sides inside the frame to move the electric slider, thereby adjusting the lateral position of the top connecting plate and the dual-axis motor. This allows the machine to accommodate stainless steel water tank plates of different widths. At the same time, the dual-axis motor drives the pressing block to rotate and press the water tank plate on the support plate through the connecting shaft and connecting strip. This effectively prevents the plate from shifting during subsequent corner cutting and grinding processes, improving the machine's adaptability to different sizes of plates and ensuring processing accuracy. This provides support for the stability of stainless steel water tank plate corner cutting processing.

[0012] Preferably, the negative pressure vacuuming assembly includes two fixed cylinders installed inside the frame. A movable block is slidably connected to a through hole on one side of each fixed cylinder. A rubber piston is fixedly connected to one end of the movable block inside the fixed cylinder. The rubber piston slides to change the air pressure inside the fixed cylinder, creating a negative pressure. The rubber piston slides and seals against the inner wall of the fixed cylinder. A connecting pipe is connected to the outside of the fixed cylinder. A connecting pipe is connected to the bottom of the connecting pipe. Multiple suction pipes are connected to the outer surface of the connecting pipe. One end of the connecting pipe is connected to a collection bucket. The negative pressure vacuuming assembly is driven by a drive assembly.

[0013] The above technical solutions not only prevent dust from polluting the workshop environment and harming the health of operators, but also prevent dust from adhering to key equipment components and affecting operational stability, as well as adhering to the surface of the sheet metal and affecting processing quality. At the same time, the centralized collection method facilitates subsequent dust cleaning and treatment, providing clean and safe working conditions for the processing of stainless steel water tank panels.

[0014] Preferably, the drive assembly includes a rotating disk mounted on another output end of the dual-axis motor. A drive block is fixedly connected to the outer eccentric part of the rotating disk. A movable frame is slidably connected to the outer surface of the rotating disk. The outer side of the movable frame is connected to the end of the movable block away from the rubber piston. A movable groove is formed on the inner side of the movable frame, and the drive block is movably disposed inside the movable groove.

[0015] The above technical solution uses a rotating disc to drive the eccentric drive block to slide in the movable groove inside the movable frame, converting the rotational motion of the dual-axis motor into the horizontal reciprocating linear motion of the movable frame. This, in turn, drives the movable block connected to the movable frame to move synchronously, providing driving force for the sliding of the rubber piston inside the fixed cylinder of the negative pressure dust collection assembly, so as to promote the formation of a stable negative pressure in the fixed cylinder without the need for an additional power source.

[0016] Preferably, an air inlet pipe is connected to the outside of the fixed cylinder, and a one-way valve is installed inside both the air inlet pipe and the connecting pipe. The two one-way valves have opposite conduction directions, and the cross-sectional area of ​​the fixed cylinder is larger than that of the connecting pipe.

[0017] Through the above technical solution, the one-way valves with opposite conduction directions installed in the air inlet pipe on the outside of the fixed cylinder and the connecting pipe ensure that external air enters the fixed cylinder only through the air inlet pipe, and the airflow carrying dust in the fixed cylinder enters the connecting pipe only through the connecting pipe, avoiding backflow of airflow and ensuring the continuity of negative pressure formation. The cross-sectional area of ​​the fixed cylinder is larger than that of the connecting pipe, which allows the air pressure in the fixed cylinder to change stably when the rubber piston slides, so as to form a reliable negative pressure. At the same time, the airflow velocity in the connecting pipe is increased due to the smaller cross-sectional area, which enhances the suction force of the suction pipe on the grinding dust. The combination of the two allows the negative pressure dust collection component to continuously and efficiently collect grinding dust, ensuring a stable and reliable dust collection effect.

[0018] Preferably, the automatic loading and unloading assembly includes a drive motor installed inside the support frame, a drive screw fixedly connected to the output end of the drive motor, a threaded bracket connected to the external thread of the drive screw, an electric telescopic rod II installed on the threaded bracket via a connecting block, a fixing plate fixedly connected to the output end of the electric telescopic rod II, and vacuum suction cups installed at the four bottom corners of the fixing plate.

[0019] Through the above technical solution, the drive motor drives the drive screw to rotate, causing the threaded frame to move along a preset direction. In conjunction with the extension and retraction of the electric telescopic rod, the vacuum suction cups at the four corners of the bottom of the fixed plate can stably grasp the stainless steel water tank plate to be processed and accurately transfer it to the support plate to complete the loading. After processing, the plate can be transferred to the designated position to achieve unloading through the same logic. The whole process does not require manual intervention, which avoids the risk of scratching the plate and personnel safety caused by manual handling, and greatly improves the loading and unloading efficiency and positional accuracy.

[0020] Preferably, guide rods are slidably connected to the two through holes on the inner side of the threaded frame, and the left and right ends of the guide rods are fixedly connected to the inner side of the support frame.

[0021] The above technical solution guides and limits the movement of the threaded frame, preventing it from rotating synchronously with the drive screw when the drive motor drives the drive screw, thus avoiding unstable linear movement.

[0022] Preferably, the polishing assembly includes four robotic arms mounted inside the frame, and the actuators of the robotic arms are equipped with polishing heads for polishing stainless steel water tanks.

[0023] The above technical solution involves setting up four robotic arms inside the frame, each corresponding to one of the four corners of the stainless steel water tank plate. The grinding heads on the robotic arm actuators can precisely target the edges of the plate after corner cutting and remove the burrs remaining from the cutting process. This eliminates the need for manual grinding, improving the efficiency of burr removal and the stability of grinding quality, while also avoiding the risk of scratches that may be caused by manual contact with sharp burrs.

[0024] Preferably, the machine also includes two placement racks, which are located on the left and right sides of the frame, respectively. The right placement rack is used to store the stainless steel water tank plate to be processed, and the left placement rack is used to store the stainless steel water tank plate after processing.

[0025] Through the above technical solutions, the two work together to achieve orderly management of stainless steel water tank panels before and after processing. This not only ensures the accuracy and continuity of the automatic loading and unloading process and reduces manual sorting and handling, but also reduces the risk of scratches and damage to the panels due to improper storage.

[0026] This invention provides an automatic loading and unloading device for stainless steel water tank panels, with four corners cut. It offers the following advantages: 1. This invention, through multi-component collaboration, achieves integrated automated operation of water tank panels, from automatic feeding, precise fixing, adaptive corner cutting, burr removal, to automatic unloading. This effectively solves the problems of low efficiency, high labor intensity, and susceptibility to precision issues associated with traditional manual processing. The automatic feeding component, through the linkage of a drive motor, drive screw, and vacuum suction cup, completes the loading, unloading, and storage of the panels to be processed, requiring no manual intervention throughout the process. The fixing component uses electric guide rails for positioning and a dual-axis motor-driven pressing block for clamping, adapting to different panel sizes and ensuring stability and no shifting during cutting, thus guaranteeing processing accuracy. The grinding component uses four sets of robotic arms to drive grinding heads for targeted burr removal, eliminating secondary processing steps and improving product quality and safety. The overall equipment boasts a high degree of automation, strong adaptability, and excellent processing quality, significantly improving batch processing efficiency and reducing labor and production costs for enterprises.

[0027] 2. This invention greatly optimizes the processing performance of stainless steel water tank panels by adding an adjustment component and a negative pressure dust collection component. The adjustment component can flexibly adjust the position of the stamping structure for corner cutting, accurately adapting to the corner cutting requirements of stainless steel water tank panels of different sizes. This effectively solves the problems of long downtime and poor adaptability caused by the need for frequent mold changes or manual structural adjustments in traditional equipment. The added negative pressure dust collection component forms a stable negative pressure based on Bernoulli's principle, which can efficiently capture the dust generated during the grinding process, preventing dust from spreading and polluting the workshop working environment and harming the health of operators.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides an automatic loading and unloading device for cutting the four corners of stainless steel water tank panels, comprising: The frame 1 serves as the supporting carrier for the entire device. A support frame 3 is fixedly installed on the top of the frame 1, and a support plate 5 for supporting the stainless steel water tank plate is fixedly installed in the middle of the inner side of the frame 1. An adjustment component, installed at the bottom of the support plate 5, is used to adjust the position of the angle-cutting stamping structure to accommodate the angle-cutting requirements of stainless steel water tank panels of different sizes. The adjustment assembly includes an electric telescopic rod 901 installed inside the frame 1. The telescopic end of the electric telescopic rod 901 is fixedly connected to a drive rack 902. The bottom of the support plate 5 is movably connected to a rotating plate 908 via a bearing. The bottom of the rotating plate 908 is fixedly connected to a drive gear 903. The outer side of the drive gear 903 meshes with the outer side of the drive rack 902. The outer side of the rotating plate 908 is rotatably connected to multiple hinge rods 905. The ends of the hinge rods 905 are hinged to swing rods 906. The inner side of the frame 1 is fixedly connected to multiple support seats 904. The outer side of the swing rod 906 is slidably connected to the upper surface of the support seat 904. A hydraulic cylinder 907 is installed on one side of the top of the swing rod 906. The output end of the hydraulic cylinder 907 is equipped with a punch head for cutting the corner of the stainless steel water tank plate.

[0032] Specifically, when the electric telescopic rod 901 inside the frame 1 is activated, its telescopic end will drive the fixedly connected drive rack 902 to move in a linear direction. Since the drive rack 902 meshes with the drive gear 903 at the bottom of the rotating plate 908, which is movably connected to the bottom of the support plate 5 via a bearing, the movement of the drive rack 902 will drive the drive gear 903 to rotate synchronously, thereby causing the rotating plate 908 to rotate smoothly around the bearing at the bottom of the support plate 5. The multiple hinge rods 905 rotatably connected to the outside of the rotating plate 908 will swing synchronously with the rotation of the rotating plate 908. The swing rods 906 hinged at the ends of the hinge rods 905 will slide along the upper surface of the multiple support seats 904 fixedly connected to the inside of the frame 1 under the traction force of the hinge rods 905. The hydraulic cylinder 907 installed on one side of the top of the swing arm 906 will adjust its position synchronously with the movement of the swing arm 906, so that the punch head installed at the output end of the hydraulic cylinder 907 will move precisely to the cutting angle position that matches the size of the stainless steel water tank plate to be processed, thereby achieving the adaptation to the cutting angle requirements of stainless steel water tank plates of different sizes.

[0033] The fixing component is installed on the inner side of the frame 1 and is set above the support plate 5. It is used to press and fix the stainless steel water tank plate when it is placed on the top of the support plate 5. The fixing assembly includes electric guide rails 701 installed on the left and right sides inside the frame 1. Electric sliders 702 are installed on the outside of the electric guide rails 701. A connecting plate 703 is installed on the top of the electric sliders 702. A dual-axis motor 707 is installed on one side of the top of the connecting plate 703. A connecting shaft 704 is fixedly connected to one of the output ends of the dual-axis motor 707. Two connecting strips 705 are fixedly connected to the outside of the connecting shaft 704. A pressing block 706 is rotatably installed on one side of the bottom end of the connecting strip 705.

[0034] Specifically, the electric guide rails 701 on the left and right sides inside the frame 1 provide lateral movement tracks for the components. The electric sliders 702 installed on the outside can move flexibly along the length of the electric guide rails 701, thereby driving the connecting plate 703 installed on the top of the electric slider 702 to adjust its position synchronously to adapt to stainless steel water tank plates of different widths. The dual-axis motor 707 installed on one side of the top of the connecting plate 703 serves as the power source. When it is necessary to fix the plate, one of the output ends of the dual-axis motor 707 will drive the fixedly connected connecting shaft 704 to rotate. The two connecting strips 705 fixed on the outside of the connecting shaft 704 swing down synchronously with the rotation of the connecting shaft 704. The pressing block 706 rotatably installed on one side of the bottom of the connecting strip 705 gradually approaches and presses the stainless steel water tank plate placed on the top of the support plate 5. The cooperation between the pressing block 706 and the support plate 5 achieves the stable fixation of the plate, preventing the plate from shifting during subsequent corner cutting and grinding, and ensuring processing accuracy.

[0035] The grinding assembly consists of four parts, each corresponding to one of the four corners of the stainless steel water tank plate. It is used to grind the edges of the stainless steel water tank plate after the corners are cut to remove burrs. The grinding assembly includes four robotic arms 6 installed inside the frame 1. The actuators of the robotic arms 6 are equipped with grinding heads 10 for grinding the stainless steel water tank.

[0036] Specifically, after the stainless steel water tank panel completes the corner trimming process, four robotic arms 6 start simultaneously. Their actuators precisely adjust the posture and distance of the grinding head 10 according to the shape and position of the edge of the panel after trimming, so that the grinding head 10 fits tightly against the trimmed edges of the four corners of the panel. Then the grinding head 10 starts and performs targeted grinding operations, removing the burrs remaining from the trimming through friction with the edge of the panel, ensuring that the edge of the panel is smooth and flat, avoiding safety hazards caused by burrs in subsequent processing or use. At the same time, the independent and coordinated operation of the four robotic arms 6 can ensure the consistency of grinding efficiency and grinding quality, and complete the fully automated burr treatment without human intervention.

[0037] The automatic loading and unloading assembly is installed on the inner side of the support frame 3. It is used to automatically feed the stainless steel water tank plate to be processed into the equipment to complete the loading, and automatically transport the stainless steel water tank plate after corner cutting and grinding to the designated position to complete the unloading. The automatic loading and unloading assembly includes a drive motor 401 installed inside the support frame 3. A drive screw 402 is fixedly connected to the output end of the drive motor 401. A threaded bracket 404 is threadedly connected to the external end of the drive screw 402. An electric telescopic rod 13 is mounted on the threaded bracket 404 via a connecting block 12. A fixing plate 11 is fixedly connected to the output end of the electric telescopic rod 13. Vacuum suction cups 14 are installed at the four corners of the bottom of the fixing plate 11. Guide rods 403 are slidably connected to two through holes on the inner side of the threaded bracket 404. Both ends of the guide rods 403 are fixedly connected to the inner side of the support frame 3.

[0038] Specifically, the drive motor 401 inside the support frame 3 provides power to the assembly, and its output end can drive the fixedly connected drive screw 402 to rotate. Since the threaded frame 404 is threadedly connected to the drive screw 402, and the two through holes inside the threaded frame 404 are slidably connected to guide rods 403 with both ends fixed to the inside of the support frame 3, the guide rods 403 can restrict the threaded frame 404 to rotate synchronously with the drive screw 402, so that the threaded frame 404 can only move stably and linearly along the length direction of the guide rods 403. The threaded frame 404 is connected to the electric telescopic rod 13 through the connecting block 12. The electric telescopic rod 13 can realize vertical telescopic movement, and its output end is fixed to the fixed plate. The 11 unit will rise and fall synchronously with the extension and retraction of the electric telescopic rod 13; the vacuum suction cups 14 installed at the four corners of the bottom of the fixed plate 11 can generate suction force. When loading, the drive motor 401 drives the threaded frame 404 to move above the stainless steel water tank plate to be processed. The electric telescopic rod 13 extends so that the vacuum suction cups 14 contact and adsorb the plate. Then the electric telescopic rod 13 retracts and the drive motor 401 drives the threaded frame 404 to move above the support plate 5. The electric telescopic rod 13 extends again to place the plate stably on the support plate 5. When unloading, the component adsorbs the processed plate using the same principle and transfers it to the designated storage location. The entire process does not require manual intervention and realizes automated loading and unloading.

[0039] The negative pressure dust collection component is installed outside the fixed component and is set in the working area of ​​the polishing component to absorb and collect the dust generated when the polishing component is working.

[0040] The negative pressure vacuuming assembly includes two fixed cylinders 805 installed inside the frame 1. A movable block 804 is slidably connected to a through hole on one side of the fixed cylinder 805. A rubber piston is fixedly connected to one end of the movable block 804 inside the fixed cylinder 805. The rubber piston changes the air pressure inside the fixed cylinder 805 by sliding, thus creating negative pressure. The rubber piston slides and seals against the inner wall of the fixed cylinder 805. A connecting pipe 807 is connected to the outside of the fixed cylinder 805. A connecting pipe 806 is connected to the bottom of the connecting pipe 807. Multiple suction pipes 809 are connected to the outer surface of the connecting pipe 806. One end of the connecting pipe 806 is connected to a collection bucket 808. The negative pressure vacuuming assembly is driven by a drive assembly.

[0041] Specifically, the component uses two fixed cylinders 805 inside the frame 1 as the basic components for generating negative pressure. The movable block 804, which is slidably connected to the through hole on one side of the fixed cylinder 805, can move back and forth along the through hole. One end of the block 804, located inside the fixed cylinder 805, is fixedly connected to a rubber piston, and the rubber piston maintains a sliding sealing fit with the inner wall of the fixed cylinder 805 to ensure that a sealed space can be formed inside the fixed cylinder 805. When the drive component moves the movable block 804, the movable block 804 synchronously pulls the rubber piston to slide inside the fixed cylinder 805. The sliding of the rubber piston changes the internal volume of the fixed cylinder 805, thereby adjusting the internal air pressure to form a negative pressure. The connecting pipe 807 connected to the outside of the fixed cylinder 805 can transmit the negative pressure to the connecting pipe 806 connected to the bottom. Multiple suction pipes 809 connected to the outer surface of the connecting pipe 806 correspond to the working area of ​​the grinding component. Under the action of negative pressure, the dust generated by grinding will be sucked into the suction pipe 809 and transported through the connecting pipe 806 to the collection bucket 808 connected to one end for collection, realizing the automated cleaning of grinding dust.

[0042] The drive assembly includes a rotating disk 801 mounted on the other output end of the dual-axis motor 707. A drive block 802 is fixedly connected to the eccentric outer part of the rotating disk 801. A movable frame 803 is slidably connected to the outer surface of the rotating disk 801. The outer side of the movable frame 803 is connected to the end of the movable block 804 away from the rubber piston. A movable groove is formed on the inner side of the movable frame 803, and the drive block 802 is movably disposed inside the movable groove. An air inlet pipe is connected to the outer side of the fixed cylinder 805. One-way valves are installed inside both the air inlet pipe and the connecting pipe 807. The two one-way valves have opposite conduction directions. The cross-sectional area of ​​the fixed cylinder 805 is larger than the cross-sectional area of ​​the connecting pipe 806.

[0043] Specifically, the drive assembly uses the other output end of the dual-axis motor 707 as its power source. When it operates, it drives the fixedly connected rotating disk 801 to rotate synchronously. The drive block 802, which is fixed at the eccentric position outside the rotating disk 801, moves in a circular motion with the rotating disk 801. Since the drive block 802 is movably set in the movable groove inside the movable frame 803, and the movable frame 803 is connected to the end of the movable block 804 away from the rubber piston, the sliding of the drive block 802 in the movable groove will convert the circular motion of the rotating disk 801 into the horizontal reciprocating movement of the movable frame 803, thereby driving the movable block 804 to slide synchronously back and forth along the through hole on one side of the fixed cylinder 805. At the same time, when the movable block 804 drives the rubber piston towards the fixed cylinder 805... When the piston moves externally, a negative pressure is formed inside the fixed cylinder 805, the one-way valve of the air inlet pipe opens to draw in external air, and the one-way valve of the connecting pipe 807 closes. When the rubber piston moves into the fixed cylinder 805, the air pressure inside the fixed cylinder 805 increases, the one-way valve of the air inlet pipe closes, and the one-way valve of the connecting pipe 807 opens, pushing the airflow to the connecting pipe 807 and the connecting pipe 806, continuously forming a stable negative pressure. The cross-sectional area of ​​the fixed cylinder 805 is larger than that of the connecting pipe 806. According to the principles of fluid mechanics, this dimensional difference can increase the airflow velocity inside the connecting pipe 806, enhance the adsorption capacity of the suction pipe 809 for grinding dust, and ensure that the dust efficiently passes through the suction pipe 809 and the connecting pipe 806 into the collection bucket 808 for collection.

[0044] It also includes two placement racks 2, which are located on the left and right sides of the frame 1, respectively. The right placement rack 2 is used to store the stainless steel water tank plate to be processed, and the left placement rack 2 is used to store the stainless steel water tank plate after processing.

[0045] When using this automatic stainless steel water tank panel loading and unloading and corner cutting equipment, its fully automatic processing flow and the working principle of each component are as follows: First, the automatic loading and unloading assembly is started to complete the loading operation: the drive motor 401 inside the support frame 3 is started, and the output end of the drive motor 401 drives the drive screw 402 to rotate at a constant speed. The threaded frame 404, which is threaded to the drive screw 402, moves steadily along the guide rod 403 until the threaded frame 404 drives the vacuum suction cup 14 to move precisely above the right side of the placement frame 2 of the machine frame 1. Then, the electric telescopic rod 13 is started, and its output end drives the fixed plate 11 to move vertically downward. The vacuum suction cup 14 contacts the stainless steel water tank plate to be processed on the right side of the placement frame 2 and generates an adsorption force to complete the plate gripping. After the adsorption is stable, the electric telescopic rod 13 is reset, and the drive motor 401 drives the threaded frame 404 to move along the guide rod 403 again, transferring the plate to be processed to the support plate 5 in the middle of the inner side of the machine frame 1. Finally, the electric telescopic rod 13 is extended to place the plate stably on the top of the support plate 5. After the sheet material is loaded, the fixing assembly is activated to achieve precise fixing: the dual-axis motor 707 in the fixing assembly is activated, one of the output ends drives the connecting shaft 704 to rotate synchronously, and the two connecting strips 705 fixed to the outside of the connecting shaft 704 swing down with the rotation of the connecting shaft 704. The pressing block 706 installed on one side of the bottom end of the connecting strip 705 gradually approaches and presses the stainless steel water tank plate on the support plate 5 to ensure that the sheet material does not shift during subsequent processing; if the sheet material to be processed is of different sizes, the electric slider 702 can be moved by the electric guide rails 701 on the left and right sides inside the frame 1. The connecting plate 703 at the top of the electric slider 702 drives the dual-axis motor 707 to adjust the lateral position as a whole to adapt to the fixing requirements of sheet materials of different widths; After fixing, the corner cutting process begins. The adjustment components and the cutting structure work together: According to the size and specifications of the stainless steel water tank plate to be processed, the electric telescopic rod 901 in the adjustment component at the bottom of the support plate 5 is activated. The telescopic end of the electric telescopic rod 901 drives the drive rack 902 to move linearly along the inner side of the frame 1. The drive rack 902 meshes with the drive gear 903 at the bottom of the rotating plate 908, causing the rotating plate 908 to rotate smoothly around the bearing at the bottom of the support plate 5. Multiple hinged rods 905 rotatably connected to the outer side of the rotating plate 908 swing with the rotating plate 908, thereby pulling the swing rod 906 hinged at its end to slide along the support seat 904 fixed on the inner side of the frame 1. The hydraulic cylinder 907 installed on one side of the top of the swing rod 906 adjusts the lateral position synchronously until the punch head at the output end of the hydraulic cylinder 907 is precisely aligned with the preset cutting position at the four corners of the plate. Then, the hydraulic cylinder 907 is activated, and its output end drives the punch head to move downward quickly, completing the one-time precise cutting of the four corners of the stainless steel water tank plate.

[0046] After the corner trimming is completed, the sanding assembly and the negative pressure dust collection assembly start simultaneously: the four robotic arms 6 on the inner side of the frame 1 correspond to the four corners of the board, and the actuators of the robotic arms 6 drive the sanding heads 10 close to the edge of the board after corner trimming to automatically sand the remaining burrs, ensuring that the edge of the board is smooth and free of sharp protrusions; at the same time, the other output end of the dual-axis motor 707 drives the rotating disk 801 to rotate coaxially, and the drive block 802 at the eccentric part of the rotating disk 801 slides in the movable groove on the inner side of the movable frame 803, pushing the movable frame 803 to move back and forth in the horizontal direction. The movable block 804 connected to the outside of the movable frame 803 slides in the through hole on one side of the fixed cylinder 805, which drives the reciprocating movement of the rubber piston. The reciprocating movement of the rubber piston changes the air pressure inside the fixed cylinder 805, forming a stable negative pressure. Under the action of negative pressure, the stainless steel dust generated by grinding is sucked in through multiple suction pipes 809 connected to the outer surface of the connecting pipe 806, enters the fixed cylinder 805 through the connecting pipe 806 and the connecting pipe 807, and is finally transported with the airflow to the collection bucket 808 connected to one end of the connecting pipe 806, so as to achieve centralized collection of dust.

[0047] Finally, the automatic loading and unloading assembly is activated to complete the unloading: the electric telescopic rod 13 drives the fixed plate 11 and the vacuum suction cup 14 to move downwards, and the vacuum suction cup 14 adsorbs the polished stainless steel water tank plate; after the adsorption is stable, the electric telescopic rod 13 resets, and the drive motor 401 drives the threaded frame 404 to move along the guide rod 403 to the left side of the frame 1, directly above the placement rack 2; the electric telescopic rod 13 is controlled to extend, and the vacuum suction cup 14 releases the adsorption force, and the processed plate is placed stably in the left side placement rack 2.
