[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In the present invention, a positioning and feeding component is provided above the positioning frame. The feeding cylinder pushes the feeding push plate to guide the plate into the opening frame and reach the shearing position of the shearing machine frame. The feeding amount acquisition device monitors the horizontal movement distance of the plate in real time to ensure that the plate accurately reaches the shearing position. The high-precision positioning ability helps to improve the shearing accuracy, reduce waste generation, and increase the material utilization rate. The automatic feeding and positioning reduce the chance of manual contact with the plate and lower the safety risk of workers during operation. Adjusting the thrust, speed of the feeding cylinder and the parameters of the feeding amount acquisition device can adapt to plates of different thicknesses, sizes and materials. The precise feeding and positioning of the positioning and feeding component contribute to achieving stable quality control, reducing size inconsistencies or quality problems caused by position deviations, and ensuring the consistency of the plate shearing process.

[0028] 2. In the present invention, a feeding monitoring device is installed on the front of the shearing machine frame. The feeding monitoring device detects the shearing depth of the plate. When the monitoring results of the plate feeding amount are consistent, the positioning lifting plate rises. The dual detection by the feeding amount acquisition device and the feeding monitoring device can monitor the position change of the plate during shearing in real time and accurately, ensure that the shearing length is highly consistent with the preset value, help reduce errors, improve the processing accuracy and consistency of the product. The dual detection can promptly detect and correct situations such as plate offset or jamming, maintain the stability and continuity of the production process, help reduce the scrap rate, improve production efficiency and material utilization rate, avoid potential safety hazards, and thus improve the safety performance during the shearing process.

[0029] 3. In the present invention, a contact sensor is installed inside the installation sink. The loading motor drives the plate placing plate to move, so that the rear end of the plate passes through the inside of the plate loading port and moves towards the opening frame for plate introduction. After the rear end of the plate contacts the contact sensor, it is blocked by the positioning lifting plate. The flattening and alignment of the loading end of the plate can ensure that the plate is in the correct position and angle before shearing, help reduce deviations during shearing, and ensure that the size and quality of the product meet the requirements. The automatic loading and positioning alignment reduce the time and labor of manual operation, enable the plate to enter the shearing position more quickly, and thus improve the overall production efficiency. The flattened and aligned plate is more stable during shearing, not prone to offset or distortion, and further improves the shearing accuracy of the plate.

[0030] 4. In the present invention, a conversion and stabilization base is installed at the telescopic end of the lifting and stabilizing hand lever. After the positioning and guiding component drives the sheet material to the designated position, the lifting and stabilizing hand lever pushes the conversion and stabilization base upward to support the sheet material, ensuring the smoothness of the sheet material placement on the fixed bearing platform, preventing the sheet material from shaking with the positioning and guiding component during its reset, which has an adverse effect on the continuous operation of the positioning and guiding component. After the positioning and guiding component resets, the conversion and stabilization base moves downward to smoothly load the sheet material above the fixed bearing platform. The sheet material is accurately positioned and stably supported before processing, reducing processing errors caused by the shaking or deviation of the sheet material, and helping to improve the accuracy of subsequent processing operations such as shearing, drilling, and cutting.

[0045] Please refer to Figure 1, Figure 4 , Figure 5 and Figure 6 , an embodiment provided by the present invention: an intelligent recognition and positioning shearing machine based on visual assistance;

[0046] It includes a positioning frame 4, a feeding frame 24 and a plate material introduction opening frame 5. The positioning frame 4 is installed on the front of the shearing machine frame 1. A positioning and guiding component is arranged above the positioning frame 4. The positioning and guiding component includes a feeding frame 24, a feeding push plate 27, a plate material introduction opening frame 5, a in-place detection top frame 6 and a positioning lifting plate 33. The feeding frame 24 is installed on the top of the positioning frame 4. The feeding push plate 27 is movably installed inside the feeding frame 24. The plate material introduction opening frame 5 is installed at the rear end of the feeding push plate 27. A plate material loading opening 25 is formed through the front of the feeding frame 24. A feeding cylinder 26 is installed on the front of the feeding frame 24, and the piston end of the feeding cylinder 26 is connected to the front end of the feeding push plate 27. A round hole groove 28 is formed through the front of the feeding frame 24, and a feeding amount acquisition device 29 is installed inside the round hole groove 28;

[0047] The positioning frame 4 supports the feeding frame 24. The feeding cylinder 26 pushes the feeding push plate 27. The feeding push plate 27 slides inside the feeding frame 24 to make the plate material introduction opening frame 5 enter the shearing position of the shearing machine frame 1. The round hole groove 28 provides an installation position for the feeding amount acquisition device 29. The feeding amount acquisition device 29 detects the distance between the feeding push plate 27 and it, and monitors the horizontal movement distance of the plate material in real time to ensure that the plate material accurately reaches the shearing position. The high-precision positioning ability helps to improve the shearing precision and thus reduce the generation of waste materials. The automatic feeding and positioning reduce the chance of manual contact with the plate material. Adjusting the thrust, speed of the feeding cylinder 26 and the parameters of the feeding amount acquisition device 29 can adapt to plate materials of different thicknesses, sizes and materials. The accurate feeding and positioning of the positioning and guiding component contribute to achieving stable quality control.

[0048] Please refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 , an intelligent recognition and positioning shearing machine based on visual assistance;

[0049] It includes a sheet material feeding rack 7, a sheet material guiding opening rack 5 and a positioning lifting plate 33. The front of the sheet cutting machine frame 1 is installed with a sheet material feeding rack 7. The sheet material feeding rack 7 and the sheet cutting machine frame 1 are connected by a horizontal connecting rod 37 and an auxiliary reinforcing diagonal rod 38. And the auxiliary reinforcing diagonal rod 38 is located below the horizontal connecting rod 37. A lead screw 39 is installed inside the sheet material feeding rack 7 through bearings. The front of the sheet material feeding rack 7 is installed with a feeding motor 40, and the output end of the feeding motor 40 is connected to the input end of the lead screw 39. A sheet material placing plate 41 is sleeved outside the lead screw 39, and the outer end of the sheet material placing plate 41 slides on the inner wall of the sheet material feeding rack 7. A limiting frame 42 is installed on the top of the sheet material placing plate 41;

[0050] An electric screw rod 31 is installed on the top of the sheet material guiding opening rack 5. The output end of the electric screw rod 31 is installed with a preliminary limiting plate 32. An installation sink 34 is opened on the front of the positioning lifting plate 33. A contact sensor 35 is installed inside the installation sink 34. A positioning lifting opening 30 is penetrated and opened at the top of the rear end of the sheet material guiding opening rack 5, and the positioning lifting plate 33 penetrates inside the positioning lifting opening 30;

[0051] The sheet material feeding rack 7 and the sheet cutting machine frame 1 are connected by a horizontal connecting rod 37 and an auxiliary reinforcing diagonal rod 38. The auxiliary reinforcing diagonal rod 38 further ensures the stability of the sheet material feeding rack 7 during use. Place the sheet to be cut on the sheet material placing plate 41. The limiting frame 42 limits the outer end of the sheet material. The feeding motor 40 runs to drive the lead screw 39 to rotate. The rotation of the lead screw 39 makes the sheet material placing plate 41 move horizontally inside the sheet material feeding rack 7. The movement of the sheet material placing plate 41 makes the rear end of the sheet material pass through the inside of the sheet material feeding opening 25 and move towards the sheet material guiding opening rack 5. The installation sink 34 provides an installation position for the contact sensor 35. The lifting drive cylinder 36 controls the working state of the positioning lifting plate 33. After the rear end of the sheet material contacts the contact sensor 35, it is blocked by the positioning lifting plate 33. Aligning the upper feeding end of the sheet material can ensure that the sheet material is in the correct position and angle before cutting, which helps to reduce deviations during the cutting process. The aligned sheet material is more stable during the cutting process and is not prone to deviation or distortion. The contact sensor 35 can adapt to sheets of different sizes, thicknesses and materials, enabling the sheet cutting machine to process a wider range of materials, enhancing the flexibility and adaptability of the production line, and helping to meet diverse market demands. Automated feeding reduces pollution such as noise and dust that may be generated during manual handling of sheet materials, helping to keep the working environment clean and quiet. The contact sensor 35 can record information such as the feeding time, position, and size of the sheet material, providing convenience for the traceability and analysis of production data. After the sheet material is aligned for feeding, the electric screw rod 31 works to drive the preliminary limiting plate 32 to move downwards to limit and fix the sheet material. The sheet material placing plate 41 resets, and the fixed sheet material is conveyed by the positioning and guiding component.

[0052] Please refer toFigure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a visual-aid-based intelligent recognition and positioning shearing machine;

[0053] It includes a fixed bearing table 2, a feeding monitoring device 11 and a plate feeding opening frame 5. A fixed bearing table 2 is installed on the bottom wall of the shearing machine frame 1. A shearing knife 10 is installed on the inner side of the top of the shearing machine frame 1 through a driving member. A feeding monitoring device 11 is installed on the front of the shearing machine frame 1. An electric control cabinet 9 is installed on the outside of the shearing machine frame 1. A shearing bottom table 12 is installed at the center of the top of the fixed bearing table 2. Alignment sliding grooves 13 are symmetrically opened on the top of the fixed bearing table 2. A pressing and shearing sliding seat 14 is fitted and installed inside the alignment sliding grooves 13. A shearing limiting frame 15 is installed on the top of the pressing and shearing sliding seat 14. A shearing limiting hand lever 16 is installed on the top of the shearing limiting frame 15. A side pressing plate 17 is installed at the telescopic end of the shearing limiting hand lever 16;

[0054] The plate feeding opening frame 5 is installed at the rear end of the feeding push plate 27. A positioning and arrival detection top frame 6 is installed on the top of the plate feeding opening frame 5. A lifting driving cylinder 36 is installed on the top of the positioning and arrival detection top frame 6. A positioning lifting plate 33 is installed at the piston end of the lifting driving cylinder 36, and the positioning lifting plate 33 is located inside the plate feeding opening frame 5;

[0055] The electric control cabinet 9 provides power support for the shearing machine. After the positioning and guiding assembly positions and conveys the plate, the feeding monitoring device 11 detects the shearing depth of the plate. When the monitoring results of the plate feeding amount are consistent, the lifting driving cylinder 36 drives the positioning lifting plate 33 to rise to release the blockage of the feeding end of the plate. When the positioning and guiding assembly resets, the plate passes through the open end of the plate feeding opening frame 5. The pressing and shearing sliding seat 14 slides inside the alignment sliding grooves 13 to drive the shearing limiting frame 15 to move towards the plate. The shearing limiting hand lever 16 drives the side pressing plate 17 to move downward to limit and press the plate. The shearing bottom table 12 cooperates with the shearing knife 10 to shear the plate.

[0056] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8 , a visual-aid-based intelligent recognition and positioning shearing machine;

A translation adjustment groove 3 is provided at the top of the fixed bearing platform 2. A bottom support distance adjustment hand lever 18 is installed on the inner wall of the translation adjustment groove 3.

A bottom sliding groove 20 is provided on the bottom wall of the translation adjustment groove 3, and the bottom end of the horizontal frame 19 slides inside the bottom sliding groove 20. A lifting and stabilizing hand lever 21 is installed inside the horizontal frame 19. A conversion and stabilization base 22 is installed at the telescopic end of the lifting and stabilizing hand lever 21. An anti-slip rubber layer 23 is installed on the top of the conversion and stabilization base 22;

[0058] A shearing plate limiting frame 15 is installed on the top of the pressing and fixing shearing plate sliding seat 14. A shearing plate limiting hand lever 16 is installed on the top of the shearing plate limiting frame 15. A side pressing plate 17 is installed at the telescopic end of the shearing plate limiting hand lever 16;

[0059] The bottom support distance adjustment hand lever 18 works to adjust the use position of the horizontal frame 19. The horizontal frame 19 slides in the bottom sliding groove 20 to ensure the stability of the adjustment process. Before the sheet is moved above the fixed bearing platform 2 and the positioning and feeding component is reset, the lifting and stabilizing hand lever 21 pushes the conversion and stabilization base 22 upward to support the sheet. The anti-slip rubber layer 23 increases the friction between the conversion and stabilization base 22 and the bottom wall of the sheet. The side pressing plate 17 limits the sheet and performs shearing processing through the shearing blade 10, ensuring the smoothness of the sheet feeding on the fixed bearing platform 2, preventing the sheet from shaking with the positioning and feeding component when the positioning and feeding component resets, which has an adverse impact on the continuous operation of the positioning and feeding component. After the positioning and feeding component resets, the conversion and stabilization base 22 moves downward to make the sheet smoothly loaded above the fixed bearing platform 2. The sheet is accurately positioned and stably supported before processing. The stable support reduces the movement and vibration of the sheet during processing, making the entire production process more stable and reliable.

The sheet loading module is electrically connected to the positioning and feeding component, the loading motor 40, the feeding cylinder 26, and the feed rate acquisition device 29. The positioning and shearing module is electrically connected to the shearing plate limiting hand lever 16, the feeding monitoring device 11, and the lifting and stabilizing hand lever 21. The intelligent positioning module receives the output signals of the feeding monitoring device 11 and the feed rate acquisition device 29. The intelligent positioning module is electrically connected to a difference comparison unit;

[0062] The intelligent controller 8 integrally drives and controls the working states of the positioning and guiding assembly, the loading motor 40, the feeding cylinder 26, the feeding amount acquisition device 29, the shearing limit hand lever 16, the material conveying monitoring device 11, and the lifting and stabilizing hand lever 21 through the sheet material loading module, the positioning and shearing module, and the intelligent positioning module. The intelligent positioning module receives the output signals of the material conveying monitoring device 11 and the feeding amount acquisition device 29. The difference comparison unit calculates and compares the monitoring results of the material conveying monitoring device 11 and the feeding amount acquisition device 29 to ensure the normal feeding amount of the sheet material. The dual detection of the feeding amount acquisition device 29 and the material conveying monitoring device 11 can monitor the position change of the sheet material during the shearing process in real time and accurately, ensure that the shearing length is highly consistent with the preset value, help reduce errors, and improve the processing accuracy and consistency of the product. The dual detection can timely detect and correct situations such as sheet material deviation or jamming, thereby maintaining the stability and continuity of the production process. The dual detection mechanism provides reliable data support for quality control. By analyzing and processing the detection data, potential quality problems can be timely detected and solved to ensure that the product quality meets the standard requirements. The dual detection method enables the shearing machine to process sheet materials of different sizes, materials, and thicknesses, enhancing the flexibility and adaptability of the production line.

[0063] The usage method of this shearing machine includes the following steps:

[0064] Step S1: First, place the sheet material to be sheared on the sheet material placement plate 41. The loading motor 40 drives the sheet material placement plate 41 to move, so that the rear end of the sheet material passes through the inside of the sheet material loading port 25 and moves in the direction of the sheet material guiding opening frame 5.

[0065] Step S2: The feeding cylinder 26 pushes the feeding push plate 27 to make the sheet material enter the shearing position of the shearing machine frame 1 through the sheet material guiding opening frame 5, and the feeding amount acquisition device 29 detects the horizontal moving distance of the sheet material.

[0066] Step S3: The material conveying monitoring device 11 detects the shearing depth of the sheet material. When the monitoring results of the sheet material feeding amount are consistent, the positioning and lifting plate 33 rises.

[0067] In step S1, the following steps are further included:

[0068] Step S11: After the rear end of the sheet material contacts the contact sensor 35, it is blocked by the positioning and lifting plate 33, and the electric screw 31 drives the preliminary limiting plate 32 to limit the loaded sheet material.

[0069] In step S3, the following steps are further included:

[0071] Working principle: When using this device, first place the sheet to be sheared on the sheet placing plate 41. The feeding motor 40 drives the sheet placing plate 41 to move, so that the rear end of the sheet passes through the inner side of the sheet feeding port 25 and moves towards the direction of the sheet guiding opening frame 5. After the rear end of the sheet contacts the contact sensor 35, it is blocked by the positioning lifting plate 33, and the electric screw 31 drives the preliminary limiting plate 32 to limit the feeding sheet.
