Modern production lines usually use material grabbing mechanisms based on PLC programming, that is, programmable logic controllers are used to write programs to achieve automatic control of material grabbing mechanisms. However, the current material grabbing mechanisms based on PLC programming still have the following shortcomings:

[0003] For example, the patent document with application number 202020583582.1 discloses a PLC-based material grabbing mechanism. The PLC-based material grabbing mechanism controls the third motor to work through the PLC controller, so that the support plate extends, thereby supporting the bottom of the material to prevent the material from falling off, so that the grabbing mechanism is more stable when grabbing the material, but it is not convenient to flexibly adjust the front and rear position and height of the grabbing, and it is not stable enough when adjusting the position, and it is easy to shake.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a material grabbing mechanism based on PLC programming is proposed. Utility Model Content

[0024] The specific operation is as follows. When in use, start the electric push rod 303, so that the electric push rod 303 drives the connecting plate 307 to move forward. The movement of the connecting plate 307 will drive the movable horizontal plate 306 to move forward. Through the sliding connection between the limiting sliding member 305 and the limiting sliding groove 304, the movable horizontal plate 306 will move forward along the lower surface of the fixed horizontal plate 302, and the movement of the connecting plate 307 will be limited and supported by the movable horizontal plate 306.

[0025] Please refer to Figure 3 , the connecting plate 307 is an integrally formed steel structure, and a grabbing assembly 4 for grabbing materials is provided on the surface of the connecting plate 307, the grabbing assembly 4 includes a connecting transverse plate 401, a hydraulic push rod 402, a fixing block 403 and a trapezoidal limiting groove 404, and the connecting transverse plate 401 is arranged on the upper side of the front surface of the connecting plate 307, the front surface of the connecting transverse plate 401 is installed with a hydraulic push rod 402, and a fixing block 403 is provided at the lower end of the front surface of the connecting transverse plate 401, and a trapezoidal limiting groove 404 is provided on the surface of the fixing block 403, the grabbing assembly 4 also includes a fixing piece 405, a grabbing clamp 406 and a reset spring 407, and a fixing piece 405 is installed at the bottom of the hydraulic push rod 402, and the fixing piece 405 is rotatably connected with the grabbing clamp 406 at both ends, and the upper end of the inner surface of the grabbing clamp 406 is connected to the reset spring 407;

[0026] The specific operation is as follows. When in use, start the hydraulic push rod 402, so that the hydraulic push rod 402 drives the grabbing clamp 406 to move downward along the inner side of the trapezoidal limiting groove 404 through the fixing part 405, until the two groups of grabbing clamps 406 are respectively placed on both sides of the material. At this time, the reset spring 407 is stretched under force, and the hydraulic push rod 402 is started to move upward. When the grabbing clamp 406 enters the inner side of the trapezoidal limiting groove 404, due to the limitation of the inner side of the trapezoidal limiting groove 404, the grabbing clamp 406 will rotate inward around the two ends of the fixing part 405 to clamp and grab the material. Due to the rebound of the reset spring 407, the two groups of grabbing clamps 406 will be further driven to clamp more tightly.

[0027] Please refer to Figure 4 A support platform 5 is installed on the lower surface of the support rod 1, and a control body 6 is arranged on the lower surface of the support platform 5. Two groups of support rods 1 are symmetrically arranged, and a fixed top plate 7 is installed on the top of the support rod 1. A fixed support plate 8 is installed on the inner side of the lower end of the support rod 1, and a servo motor 9 is installed on the lower surface of the fixed support plate 8. The output end of the servo motor 9 is connected to a threaded screw 10 through a coupling, and the surface of the threaded screw 10 is threadedly connected to the surface of the support cross plate 2;

[0028] The specific operation is as follows. When in use, start the servo motor 9, so that the servo motor 9 drives the threaded screw 10 to rotate, and further drives the supporting cross plate 2 to move up and down along the surface of the threaded screw 10, so as to adjust the height of the grabbed material. When the supporting cross plate 2 moves, both ends will slide up and down along the surface of the support rod 1, and will be limited by the support rod 1 to prevent movement deviation.

[0029] In summary, if Figures 1 to 4As shown, when the material grabbing mechanism based on PLC programming is used, first, the servo motor 9 is started, so that the servo motor 9 drives the threaded screw 10 to rotate, and further drives the supporting cross plate 2 to move up and down along the surface of the threaded screw 10, so as to adjust the height of the grabbed material. When the supporting cross plate 2 moves, both ends will slide up and down along the surface of the supporting rod 1, and will be limited by the supporting rod 1 to prevent movement deviation. Subsequently, the electric push rod 303 is started, so that the electric push rod 303 drives the connecting plate 307 to move forward. The movement of the connecting plate 307 will drive the movable cross plate 306 to move forward. Through the sliding connection between the limiting sliding member 305 and the limiting slide groove 304, the movable cross plate 306 will move forward along the lower surface of the fixed cross plate 302 , the movement of the connecting plate 307 is limited and supported by the movable cross plate 306, and then the hydraulic push rod 402 is started, so that the hydraulic push rod 402 drives the grabbing clamp 406 to move downward along the inner side of the trapezoidal limiting groove 404 through the fixing piece 405 until the two groups of grabbing clamps 406 are respectively placed on both sides of the material. At this time, the reset spring 407 is stretched by force, and the hydraulic push rod 402 is started to move upward. When the grabbing clamp 406 enters the inner side of the trapezoidal limiting groove 404, due to the limitation of the inner side of the trapezoidal limiting groove 404, the grabbing clamp 406 will rotate inward around the two ends of the fixing piece 405 to clamp and grab the material. Due to the rebound of the reset spring 407, the two groups of grabbing clamps 406 will be further driven to clamp more tightly.
