DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 3 The present invention provides an embodiment of a device for screening material height for a riveting press, comprising a support frame 1, which serves as the basic structure of the entire device. A conveyor belt 2 is fixedly connected to the top left side of the support frame 1. The conveyor belt 2 is used to transport materials to subsequent processing units. A touch screen 3 is fixedly connected to the top front side of the support frame 1, providing a human-machine interface. The operator can use the touch screen 3 to monitor the operating status of the device in real time, set or adjust parameters (such as material discharge speed, material detection accuracy, etc.), and start or stop the device. The touch screen 3 provides an intuitive and convenient operation mode for the operation and control of the device. The top rear side of the support frame 1 is fixedly connected with an adjustment component for adjusting the material position. The top front right end of the conveyor belt 2 is fixedly connected with a quantitative component for quantitatively discharging the material. The top rear side of the support frame 1 is fixedly connected with a screening component for screening the pushed material. The top front side of the support frame 1 is fixedly connected with a detection component for detecting the material. The top front side of the support frame 1 is fixedly connected with a defective product discharge pipe 17. The top right side of the support frame 1 is fixedly connected with a good product discharge pipe 18.

[0036] Reference Figure 1 and Figure 4 The adjustment component includes an electric push rod 4, the bottom of which is fixedly connected to the top rear side of the support frame 1, and the output of the electric push rod 4 is fixedly connected to a baffle 5. By adjusting the telescopic movement of the electric push rod 4, the baffle 5 can move left and right, thereby adjusting the position of the material on the conveyor belt 2, preventing the material from shifting, and ensuring that the material accurately enters the subsequent processing area during the conveying process;

[0037] Reference Figure 3 and Figure 7 The detection component includes an electric push rod 13. The bottom of the electric push rod 13 is fixedly connected to the top front side of the support frame 1. The output end of the electric push rod 13 is fixedly connected to a connecting plate 14. The rear side of the connecting plate 14 is fixedly connected to a mounting plate 15. Four displacement sensors 16 are set on the outside of the mounting plate 15. These displacement sensors 16 can detect the size or other physical parameters of the material to ensure that only materials that meet the requirements can pass. Through the movement of the electric push rod 13, the detection component can detect materials at different heights to ensure the accuracy of the screening process.

[0038] Reference Figure 2 、 Figure 5 and Figure 6 The quantitative component includes a motor 6, the bottom of which is fixedly connected to the right end of the top front side of the conveyor belt 2, and the output end of the motor 6 is fixedly connected to a baffle 2 7. When the motor 6 is running, the baffle 2 7 will control the quantitative discharge of the material according to the set parameters. In this way, the material can be transported to the position of the detection component in precise quantities to ensure the accuracy of subsequent detection. The screening component includes an electric guide rail 8, the bottom of which is fixedly connected to the top rear side of the support frame 1, the external sliding connection of the electric guide rail 8 is connected to a moving block 9, the top of the moving block 9 is fixedly connected to an electric guide rail 2 10, the external sliding connection of the electric guide rail 2 10 is connected to a sliding plate 11, and the left and right sides of the top of the sliding plate 11 are fixedly connected to a push plate 12. By controlling the movement of the electric guide rail 8 and the electric guide rail 2 10, the sliding plate 11 drives the push plate 12 to screen the material, and pushes the qualified and inferior materials into different discharge pipes respectively;

[0039] Reference Figure 3 and Figure 8 The front and rear sides of the good product discharge pipe 18 are fixedly connected to a fixed plate 19. The adjacent sides of the two fixed plates 19 are rotatably connected to a rotating plate 20. The adjacent sides of the two rotating plates 20 are fixedly connected to a limit plate 21. The setting of the fixed plate 19 and the rotating plate 20 is used to support and adjust the limit plate 21 to control the falling speed and direction of the material. The front and rear sides of the good product discharge pipe 18 are fixedly connected to a receiving column 22. The outside of the two receiving columns 22 is provided with a spring 23. The spring 23 provides a buffering effect to prevent the material from being damaged when falling. The adjacent sides of the two receiving columns 22 are slidably connected to a telescopic column 24. The adjacent sides of the two telescopic columns 24 are fixedly connected to a force plate 25. The adjacent sides of the two force plates 25 are rotatably connected to a fixed plate 26. The force plate 25 can be fine-tuned according to the weight of the material or the impact of falling, further preventing the material from being damaged. The rotating connection between the two force plates 25 and the fixed plate 26 ensures the flexibility of the system.

[0040] Working Principle: First, the material is placed onto the device's conveyor belt 2. Conveyor belt 2 is an automatic conveying system that transports the material from its initial position to various processing units by controlling its speed and direction. The design of conveyor belt 2 allows for the smooth transportation and precise positioning of the material to avoid any deviation or error during the conveying process. To prevent the material from shifting during the conveying process, the device is designed with an adjustment component, which consists of an electric push rod 4 and a baffle 5. Through the telescopic action of the electric push rod 4, the baffle 5 can move left and right on the conveyor belt 2, thereby adjusting the position of the material, ensuring that the material travels along the predetermined path and maintaining its stability and accuracy during the conveying process.

[0041] Once the material is delivered to the designated location, the dosing component begins to function. This component, via motor 1 (6), drives a baffle 2 (7) to control the amount of material delivered. Motor 1 (6) precisely controls the amount of material delivered to the subsequent inspection area by setting parameters. This dosing method not only ensures a consistent amount of material delivered each time, thereby improving production efficiency, but also provides an accurate material baseline for the inspection process, effectively enhancing the precision and accuracy of detection.

[0042] Next, the material enters the inspection assembly area. The core of the inspection assembly consists of an electric push rod 13 and a displacement sensor 16 mounted on it. The electric push rod 13 drives the inspection assembly to accurately inspect materials of varying heights and sizes. The displacement sensor 16 measures the material's size, shape, and other physical parameters in real time, ensuring that only materials that meet the requirements pass inspection. This inspection process not only filters out non-compliant materials but also enables rapid screening based on pre-defined criteria, thereby improving the efficiency of the entire production line.

[0043] Qualified materials are then transported to the screening assembly. The screening assembly consists of multiple motorized guide rails 8, moving blocks 9, and push plates 12. The motorized guide rails 8 control the movement and operation of the entire assembly. Driven by the motorized guide rails 8, the push plates 12 move in different directions, thereby classifying and separating the materials. By precisely controlling the position and speed of the push plates 12, the screening assembly effectively separates qualified materials from inferior materials and directs them into separate discharge channels.

[0044] For the qualified materials that have been screened out, they will be introduced into the good product discharge pipe 18. The design of the good product discharge pipe 18 takes into account the speed and protection of the material during the falling process. Inside the discharge pipe, multiple limit plates 21 and spring 23 structures are set. These structures work together to control the falling speed and direction of the material. The limit plate 21 can perform effective limiting operations during the falling process of the material to prevent the material from getting out of control due to gravity; and the spring 23 structure provides a buffer mechanism that can absorb part of the kinetic energy of the material when it falls, slowing down its falling speed, and avoiding collisions or damage due to falling too quickly. This design not only effectively protects the material, but also ensures the quality of the final product.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
