Under the action of the nitrogen cylinder, the upper knife will move upward, and the cleaning brush will exert force on the upper knife to clean off the metal debris attached to both sides of the upper knife.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses a high-resolution camera to first acquire an image of the metal sheet on the automatic feeding mechanism, and then uses image processing technology to analyze the edge, shape and surface features of the metal sheet, extracts the geometric features and size information of the metal sheet from the processed image, and then obtains the thickness of the sheet based on the extracted features, and then determines whether double-layer sheet overlap occurs. If double-layer sheet overlap occurs, the automatic feeding mechanism is controlled to transport the sheet back to the material discharging frame, and the suction force of the automatic feeding mechanism is adjusted through the PLC controller to realize the sheet separation function, which can further ensure the stability and accuracy of the metal sheet during the shearing process and avoid shearing problems caused by sheet adhesion or overlap.

[0016] 2. The present invention uses an automatic feeding mechanism to transport the metal sheets to be sheared in the feeding frame. The automatic feeding mechanism feeds the prepared metal sheets into the shearing machine for processing according to a predetermined route, and repeats the transporting work to ensure that the metal sheets are transported to a fixed position. When the detection knife has double-layer overlap, the distribution of its internal magnetic circuit is controlled and converted through the PLC controller, thereby changing the suction force of the electro-permanent magnetic suction cup on the metal sheet, realizing the function of separating the metal sheets, so that only one layer of metal sheet is transported each time. Since the automatic feeding mechanism performs reciprocating motion, the accuracy of the placement of the metal sheets can be ensured, thereby ensuring the high efficiency and high quality of the production process, and effectively improving the shearing efficiency.

[0017] 3. The present invention controls the operation of motor 2 to drive the bidirectional screw to rotate, so that the two groups of cleaning brushes approach the upper knife along the guide rod 3, so that the two groups of cleaning brushes clamp the upper knife in the middle, and release the energy stored in the nitrogen cylinder due to the compression of nitrogen to push the upper knife to rise. At the same time, due to the force of the cleaning brush on the upper knife, metal debris and other impurities attached to the surface of the upper knife can be removed, and the cleanliness of the upper knife can be maintained. The removed metal debris and other impurities will fall into the waste box under the action of gravity, which effectively reduces the manual procedures and greatly improves the shearing work efficiency.

[0018] 4. The present invention supports the metal sheets immediately after separation through the conveying device, which can effectively prevent the metal sheets from additional bending due to their own weight, improve the quality of the sheared metal sheets, and then use the conveying device to convey the sheared metal sheets out of the shearing machine, and then use the automatic feeding mechanism to absorb the sheared metal sheets and place them in the discharge frame.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Fig.10 , an embodiment provided by the present invention: an intelligent shearing machine with automatic loading and unloading functions and a method for using the same, comprising a PLC controller, a shearing machine 1 and two sets of feeding frames 3, wherein the two sets of feeding frames 3 are respectively located in front of and behind the shearing machine 1, the PLC controller is used to control the shearing machine 1 to shear metal sheets, and the two sets of feeding frames 3 are respectively used to place unsheared metal sheets and sheared metal sheets; The front and back sides of the shearing machine 1 are provided with feeding ports, a high-resolution camera 4 is installed on the front side of the shearing machine 1, and the high-resolution camera 4 is located above the feeding port, the front and back sides of the shearing machine 1 are provided with top plates 2, and an automatic feeding mechanism is installed inside the top plates 2.

[0025] Furthermore, the PLC controller is used to control the working condition and efficiency of the entire shearing machine 1. The two sets of feeding frames 3 are respectively used to place the metal sheets to be sheared and the sheared metal sheets. The automatic feeding mechanism is first used to transport the metal sheets to be sheared in the feeding frame 3. The automatic feeding mechanism feeds the prepared metal sheets into the shearing machine 1 for processing according to a predetermined route. The transporting work is repeated to ensure that the metal sheets are transported to a fixed position. During the transporting process, the high-resolution camera 4 first acquires an image of the metal sheet on the automatic feeding mechanism, and then uses image processing technology to analyze the edge, shape and surface features of the metal sheet, extracts the geometric features and size information of the metal sheet from the processed image, and then uses the extracted image to obtain the image of the metal sheet. The thickness of the plate is obtained based on the characteristics, and then it is determined whether double-layer plate overlap occurs. If double-layer plate overlap occurs, the automatic feeding mechanism is controlled to transport the plate back to the discharge frame 3, and the suction force of the automatic feeding mechanism is adjusted by the PLC controller to realize the plate separation function, which can further ensure the stability and accuracy of the metal plate during the shearing process and avoid shearing problems caused by plate adhesion or overlap. In actual use, acoustic wave detection can be used to determine whether double-layer plate overlap occurs, and the difference in the propagation speed of acoustic waves in different media can be used to identify whether a double-layer plate exists. The actual weight of the metal plate can also be compared with the theoretical weight of the single-layer plate through weight detection. If it exceeds the expected range, it is a double-layer plate overlap.

[0026] See also Figure 4 and Figure 5 , an embodiment of the present invention: an intelligent shearing machine with automatic loading and unloading functions and a method for using the same, the automatic feeding mechanism comprises a control motor 5 installed on the top of a top plate 2, a coupling 6 is installed at the output end of the control motor 5, a reducer 7 is installed at one end of the coupling 6, a screw 9 is installed at the output end of the reducer 7, a slide groove is provided inside the top plate 2, and the slide groove is Π-shaped, two groups of guide rods 10 are installed inside the top plate 2, and the guide rods 10 are located on both sides of the screw 9, the outer surfaces of the guide rods 10 and the screw 9 are sleeved with a connecting block 8, and the connecting block 8 is located inside the slide groove, two groups of electric telescopic rods 11 are installed at the bottom of the connecting block 8, and the output ends of the two groups of electric telescopic rods 11 are installed with a support plate 14, and the bottom of the support plate 14 is evenly arranged with electric permanent magnetic suction cups 13.

[0027] Furthermore, the control motor 5 converts electrical energy into mechanical energy, and the coupling 6 firmly connects the control motor 5 with the reducer 7, thereby transmitting the movement and torque of the control motor 5 to the reducer 7. The coupling 6 can allow a certain axial or radial offset to compensate for the changes caused by installation errors or thermal expansion, and can also relieve impact and reduce vibration. The reducer 7 reduces the input speed and increases the output torque to adjust to the required speed and torque, thereby driving the screw 9 to rotate, so that the connecting block 8 moves along the direction of the guide rod 10, thereby driving the electric telescopic rod 11, the support plate 14 and the electric permanent magnetic suction cup 13 to move, and at the same time controlling the electric telescopic rod 11 to extend, and the electric permanent magnetic suction cup 13 is close to the metal plate, and at the same time the electric permanent magnetic suction cup 13 is energized. When current passes through the electric permanent magnetic suction cup 13, a magnetic field is generated inside. In the magnetized state, the electric permanent magnetic suction cup The lower magnet and the upper magnet of the disk 13 have the same polarity, and the magnetic field lines penetrate the surface of the permanent magnetic suction cup 13 and pass through the metal sheet, thereby firmly sucking the metal sheet. When the detection knife has double overlap, the distribution of its internal magnetic circuit is controlled and converted through the PLC controller, thereby changing the suction force of the permanent magnetic suction cup 13 on the metal sheet, realizing the function of separating the metal sheets, so that only one layer of metal sheet is transported each time. After the shearing is completed, the automatic feeding mechanism transports the sheared metal sheet to the discharge frame 3. At this time, the permanent magnetic suction cup 13 is controlled by the PLC controller to be demagnetized, and the permanent magnetic suction cup 13 has no suction force on the metal sheet, and then the sheared metal sheet is placed in the discharge frame 3. Since the automatic feeding mechanism performs reciprocating motion, the accuracy of the placement of the metal sheet can be ensured, so as to ensure the high efficiency and high quality of the production process, and effectively improve the shearing efficiency.

[0028] See also Figure 1 , Figure 3 and Figure 6 An embodiment of the present invention is: an intelligent shearing machine with automatic loading and unloading functions, a groove is opened on the inner wall of one side of the shearing machine 1, a control motor 2 34 and a guide rod 3 36 are installed inside the groove, and the guide rod 3 36 is located on one side of the control motor 2 34, a bidirectional screw rod 35 is installed at the output end of the control motor 2 34, two groups of connecting parts are sleeved on the outer surfaces of the bidirectional screw rod 35 and the guide rod 3 36, a cleaning brush 23 is installed at one end of the two groups of connecting parts, a camera 24 is installed on the front wall and the rear wall of the shearing machine 1, and the camera 24 is located above the feeding port, and a waste box 30 is movably installed on the outer wall of one side of the shearing machine 1.

[0029] Furthermore, after the shearing is completed, the control motor 2 34 is operated to drive the bidirectional screw rod 35 to rotate, so that the two groups of cleaning brushes 23 are close to the upper knife 22 along the guide rod 3 36, so that the two groups of cleaning brushes 23 clamp the upper knife 22 in the middle, and release the energy stored in the nitrogen cylinder 20 due to the compression of the nitrogen to push the upper knife 22 to rise. At the same time, due to the force of the cleaning brush 23 on the upper knife 22, the metal debris and other impurities attached to the surface of the upper knife 22 can be removed, and the cleanliness of the upper knife 22 can be maintained. The removed metal debris and other impurities will fall into the waste box 30 under the action of gravity, which effectively reduces the manual procedures and greatly improves the efficiency. In order to improve the shearing efficiency, some metal debris may fall on the surface of the conveyor belt 15 and the lower knife 21. It is only necessary to clean the conveyor belt 15 and the lower knife 21 regularly. In addition, the upper knife 22 needs to be checked and replaced regularly to avoid long-term use of the upper knife 22 to cause serious wear of the upper knife 22, thereby affecting the cutting efficiency and quality. The staff regularly uses special lubricants to keep the tool surface in good lubrication. The camera 24 is used to identify the residual impurities and the degree of wear on the upper knife 22, and monitor the internal operation of the shearing machine 1 at the same time, which helps the staff to adjust the working parameters in time and discover abnormal conditions of the machine.

[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 , an embodiment provided by the present invention: an intelligent shearing machine with automatic loading and unloading functions, a conveying device is installed throughout the interior of the shearing machine 1, and the conveying device is located below the feeding port, and the conveying device is located above the waste box 30, a pressing cylinder 19 and a nitrogen cylinder 20 are installed on the top wall of the shearing machine 1, and the nitrogen cylinder 20 is located behind the pressing cylinder 19, and the pressing cylinder 19 is located above the conveying device, and an upper knife 22 is installed at the output end of the nitrogen cylinder 20, and the upper knife 22 is located between two sets of cleaning brushes 23; The conveying device includes a motor box 16 installed on the outer wall of one side of the shearing machine 1, a servo motor 17 is installed inside the motor box 16, a rotating shaft 18 is installed on the output end of the servo motor 17 and inside the shearing machine 1, and the outer surfaces of the two groups of rotating shafts 18 are sleeved with conveyor belts 15, and the conveyor belts 15 are located above the pressing cylinder 19; A protective frame 25 is installed on the inner wall of one side of the shearing machine 1, and a sliding groove is opened inside the protective frame 25. A stepper motor 27 is embedded and installed inside the protective frame 25. A screw rod 28 is installed at the output end of the stepper motor 27, and the screw rod 28 is located inside the sliding groove. A guide rod 29 is installed inside the sliding groove. The outer surfaces of the guide rod 29 and the screw rod 28 are sleeved with a connecting short rod. A baffle plate 26 is installed at one end of the connecting short rod, and the baffle plate 26 is located above the conveying device. The baffle plate 26 is located behind the cleaning brush 23. A pressure sensor 12 is installed on the front of the baffle plate 26, and the pressure sensor 12 is electrically connected to the PLC controller.

[0031] Further, the motor box 16 runs, driving the rotating shaft 18 to rotate, and then driving the conveyor belt 15 to rotate, so as to convey the metal sheet on the conveyor belt 15, and convey the metal sheet to the shearing machine 1. When the pressure sensor 12 receives pressure, the conveying device stops running, and at the same time, the pressing cylinder 19 extends to clamp and position the metal sheet below to avoid movement and jumping during shearing, so as to ensure the accuracy and efficiency of shearing. After fixing, the metal sheet can be sheared, and the nitrogen cylinder 20 is started to extend to drive the upper knife 22 to move downward, and then the metal sheet below is sheared. When the upper knife 22 is pressed down, the nitrogen is compressed and stores energy. When the upper knife 22 needs to return, the stored energy is released to push the upper knife 22 up, so as to realize the rapid return of the upper knife 22. The lower knife 21 is fixed, through The upper knife 22 moves downward and applies pressure to the metal sheet. When the upper knife 22 and the lower knife 21 are closed, the shearing force generated will cut the metal sheet. The sheared metal sheet will be supported by the conveying device. Since the conveying device immediately supports the metal sheets after separation, it can effectively prevent the metal sheets from additional bending due to their own weight, thereby improving the quality of the sheared metal sheet. After the shearing is completed, the stepper motor 27 is controlled to run, driving the second screw rod 28 to rotate, so that the baffle plate 26 moves up along the direction of the second guide rod 29, so that the sheared metal sheet can be moved out of the shearing machine 1, and then the conveying device is started to convey the sheared metal sheet out of the shearing machine 1, and then the automatic feeding mechanism is used to absorb the sheared metal sheet and place it in the discharge frame 3, thereby reducing manual processes and improving the overall shearing work efficiency.

[0032] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: an intelligent shearing machine with automatic loading and unloading function, an electrical box 31 and a display screen 32 are installed on one side outer wall of the shearing machine 1, and the display screen 32 is located in front of the electrical box 31, and the display screen 32 and the electrical box 31 are located above the waste box 30, an emergency stop button is installed on the display screen 32, and the emergency stop button is responsible for forcibly stopping the operation of the shearing machine 1 in an emergency; The inner wall of the shearing machine 1 is provided with a lower knife 21, and the lower knife 21 is located between the waste box 30 and the upper knife 22. The outer wall of the other side of the shearing machine 1 is provided with a box door 33 through hinges.

[0033] Furthermore, the staff can adjust the parameters and monitor the entire shearing process through the display screen 32. When encountering abnormal machine operation or dangerous situations, they can immediately press the emergency stop button to quickly cut off the power supply of the shearing machine 1 to prevent potential injuries. For example, during the shearing process, when the metal sheet is stuck or the machine fails, the emergency stop button can help avoid more serious mechanical damage or personal safety threats. The box door 33 makes it convenient for the staff to regularly clean, inspect and repair the internal parts.

[0034] Furthermore, the method for using the intelligent shearing machine with automatic loading and unloading functions includes the following steps: Step S1, firstly, the automatic feeding mechanism is used to automatically transport the metal sheet to be cut in the material discharging frame 3 to the conveying device, and at the same time, the high-resolution camera 4 obtains the image of the metal sheet, and uses the image processing technology to determine whether the sucked metal sheet has double-layer sheet overlap; Step S2, the metal sheet is moved to the shearing machine 1 under the conveying action of the conveying device. When the pressure sensor 12 receives pressure, the conveying device stops moving, and the pressing cylinder 19 is extended to position the sheet. Then, the nitrogen cylinder 20 is started to drive the upper knife 22 to move downward to shear the metal sheet. Step S3: After the cutting is completed, the metal debris attached to the surface of the upper knife 22 is removed using the cleaning brush 23, so that the metal debris falls into the waste box 30 below under the action of gravity; Step S4, after the shearing is completed, the baffle plate 26 is moved upward, and the conveying device is controlled to continue to move, the sheared plate is moved out of the shearing machine 1, and the automatic feeding mechanism is used to transport the plate to the discharge frame 3 behind the shearing machine 1.

[0035] In step S1, the following steps are also included: Step S11, control the motor 5 to run, then transmit power through the coupling 6, and then adjust the speed and torque through the reducer 7, and finally drive the screw 9 to rotate, so that the connecting block 8 is close to the discharge frame 3 along the direction of the guide rod 10, and then the electric telescopic rod 11 is extended, so that the electric permanent magnetic suction cup 13 is close to the metal plate, and generates suction force on the metal plate to transport the plate. If the overlap of double-layer plates is detected, the metal plate is put back into the discharge frame 3, and the suction force of the electric permanent magnetic suction cup 13 is adjusted through the electrical box 31; In step S3, the following steps are also included: Step S31, start the control motor 2 34, drive the bidirectional screw 35 to rotate, so that the two sets of cleaning brushes 23 move along the direction of the guide rod 3 36 and approach the middle upper knife 22. Under the action of the nitrogen cylinder 20, the upper knife 22 will move upward, and the cleaning brush 23 will exert a force on the upper knife 22 to clean off the metal debris attached to both sides of the upper knife 22.

[0036] Working principle: first use the automatic feeding mechanism to transport the metal sheet to be sheared in the discharge frame 3, and the automatic feeding mechanism feeds the prepared metal sheet into the shearing machine 1 for processing according to the predetermined route, and repeats the transport work. During the transport process, the high-resolution camera 4 first acquires an image of the metal sheet on the automatic feeding mechanism, and then uses image processing technology to analyze the edge, shape and surface features of the metal sheet, extracts the geometric features and size information of the metal sheet from the processed image, and then obtains the thickness of the sheet based on the extracted features, and then determines whether double-layer sheet overlap occurs. If double-layer sheet overlap occurs, control the automatic feeding mechanism to transport the sheet back to the discharge frame 3, and adjust the suction force of the automatic feeding mechanism through the PLC controller to realize the sheet separation function, and feed a layer of metal sheet into the shearing machine 1 for shearing; The sheared metal sheet will be held by the conveying device. Since the conveying device supports the metal sheet immediately after it is separated, it can effectively prevent the metal sheet from being bent additionally due to its own weight. Then, the sheared metal sheet is placed in the discharge frame 3 under the action of the conveying device and the automatic feeding mechanism. At the same time, the motor 2 34 is controlled to run, driving the bidirectional screw rod 35 to rotate, so that the two groups of cleaning brushes 23 approach the upper knife 22 along the guide rod 3 36, so that the two groups of cleaning brushes 23 clamp the upper knife 22 in the middle, releasing the energy stored in the nitrogen cylinder 20 due to the compression of nitrogen to push the upper knife 22 to rise. At the same time, due to the force of the cleaning brush 23 on the upper knife 22, the metal debris and other impurities attached to the surface of the upper knife 22 can be removed, and the cleanliness of the upper knife 22 can be maintained. The removed metal debris and other impurities will fall into the waste box 30 under the action of gravity, effectively reducing the manual procedures and greatly improving the shearing work efficiency.
