[0024] The features of the present utility model and other related features are further described in detail through the following examples for the understanding of technicians in the same industry:

[0025] As shown in Figure 1 and Figure 2 , an automatic device for preventing plate scratching and positioning includes a device body, the device body includes:

[0026] A weighing platform 1 for placing a plate to be measured 100 thereon and detecting the weight of the plate to be measured 100;

[0027] A visual detection camera 2 arranged above the weighing platform 2 for downward area detection of the plate to be measured 100 on the weighing platform 2;

[0028] An air floating platform 3 arranged on one side of the weighing platform 2 for receiving the plate to be measured 100 from the weighing platform 1;

[0029] An adjusting component 4 for controlling the air volume of the air floating platform 3 according to the detected weight of the weighing platform 1 and the detected area of the visual detection camera 2;

[0030] The surface of the air floating platform 3 is a first inclined surface 51, and a plurality of inclined air outlet holes 52 consistent with the inclined direction of the first inclined surface 51 are arranged on the first inclined surface 51. In a specific implementation, the visual detection camera is a CCD camera.

[0031] As described above, the weighing platform, the visual detection camera, and the air floating platform are integrated, real-time detection of the weight and area of the plate is realized, and integrated processing of air floating conveying is realized, thereby greatly improving the production efficiency and the degree of automation. The air volume of the air floating platform is intelligently adjusted according to the weighing and visual detection data by the adjusting assembly, so that the stability and safety of the plate in the conveying process are ensured, and the problem of scratching or displacement caused by improper air volume is avoided. Moreover, through the cooperation of the weighing platform, the visual detection camera, the air floating platform, and the adjusting assembly, the device can intelligently adjust according to plates of different specifications and weights, and has strong adaptability and is convenient for production management. The air floating platform is designed with a first inclined surface and inclined air outlet holes, the air flow distribution is optimized, the direct contact area between the plate and the air floating platform is reduced, and the risk of plate scratching is significantly reduced. The design of the first inclined surface enables the plate to automatically slide down the inclined surface under the action of gravity, realizes automatic guiding and positioning of the plate, improves the positioning accuracy and efficiency, and reduces the need for manual intervention.

[0032] As a preferred implementation, the first inclined surface 51 is an inclined surface extending downward from the direction close to the weighing platform 1. In this way, the extension direction of the first inclined surface can correspond to the initial position of the plate, the distance of moving the plate can be shortened, and the plate can slide downward along the first inclined surface under the action of gravity, thereby improving the operation efficiency.

[0033] As a preferred implementation, the inclination angle of the inclined air outlet hole is greater than the inclination angle of the first inclined surface 51.

[0034] As described above, by setting the inclination angle of the inclined air outlet hole to be greater than the inclination angle of the first inclined surface, the air flow will impact the bottom of the plate at a steeper angle when being ejected, so that the impact force of the air flow is effectively utilized to float the plate and keep it at a certain height, thereby enhancing the air floating effect to realize stable conveying and prevent the plate from being scratched. Moreover, since the air flow impacts the plate at a steeper angle, the contact area of the plate with the first inclined surface in the air floating state will be correspondingly reduced, further reducing the risk of scratching of the plate due to friction in the conveying process, and also helping to reduce the resistance caused by contact, so that the plate can slide down the inclined surface more smoothly.

[0035] As Figure 1 and Figure 2As shown, as a preferred embodiment, the air flotation platform 3 includes: a bellows 31 at the top and an air duct 32 arranged below the bellows 31 to supply air to the bellows 31. The top wall of the bellows 31 is a solid structure, and the bottom of the top wall is a hollow structure. The top surface of the top wall of the bellows 31 is the surface of the air flotation platform 3; the oblique air outlet 52 is a strip-shaped through hole extending obliquely downward from the top surface of the top wall to the bottom surface of the top wall. In specific implementation, the bellows 31 receives the air supply through the air duct 32 and forms a uniform airflow inside it. Subsequently, these airflows are ejected obliquely downward at a certain angle through the oblique air outlet 52, covering the entire surface of the air flotation platform. This design ensures that the plate can be supported by uniform and stable airflow during the flotation process, reducing vibration or deviation caused by uneven airflow.

[0036] As described above, the bellows 31 is designed to have a solid top and a hollow bottom structure, so that the entire air flotation platform can efficiently utilize space to accommodate the air supply system while maintaining sufficient strength, which not only reduces the use of materials but also improves the overall compactness of the equipment. The bellows 31 receives the air supply through the air duct 32 and forms a uniform airflow inside it. The oblique air outlet 52 is designed as a strip-shaped through hole extending obliquely downward from the top surface of the top wall to the bottom surface of the top wall. This shape and layout allows the airflow to act more directly and effectively on the bottom of the plate, so as to further enhance the stability of the air flotation and make the plate more stable and safe during transportation.

[0037] As a preferred embodiment, the top wall of the bellows 31 is thicker than its left and right side walls and bottom wall. This allows the top wall of the bellows 31 to serve as the direct bearing surface of the air flotation platform. Increasing the top wall thickness ensures the bellows' load-bearing capacity while saving costs, providing a more stable support surface and reducing the risk of airflow uniformity affected by structural deformation.

[0038] like Figure 2 As shown, in a specific implementation, the air flotation platform 3 is provided with a blocking wall 6 protruding upward from the extended end of the first inclined surface 51. This prevents panels placed on the first inclined surface 51 from accidentally sliding off the edge of the platform during the air flotation descent, ensuring the safety of the panels during transportation and avoiding damage or injury caused by sliding.

[0039] As a preferred embodiment, the regulating assembly 4 is an electric regulating valve, which is electrically connected to the weighing platform 1 and the air flotation platform 3. In this way, the electric regulating valve controls the air flow output of the air flotation platform 3 to achieve precise adjustment of the air flotation height of the panel.

[0040] And the electric regulating valve has high regulating precision, can rapidly adjust the airflow output of the air floating platform 3 according to the real-time feedback of the weight information of the plate on the weighing platform 1, and ensures that the plate maintains stable air floating state during the conveying process, which helps to reduce the damage risk of the plate caused by vibration or deviation.

[0041] As shown in Figure 1 The device body further comprises an upper feeding platform 7 arranged on the other side of the weighing platform 1 for conveying and preparing the to-be-tested plate, and a lower discharging platform 8 arranged on the side of the air floating platform 3 away from the weighing platform 1 for receiving and discharging the to-be-tested plate. In this way, the existence of the upper feeding platform 7 makes the to-be-tested plate be placed and prepared for conveying to the weighing platform 1 without affecting the current plate detection or processing. Similarly, the lower discharging platform 8 provides instant receiving and storage space for the plate which has completed detection or processing, realizes the continuous operation of the production line, and significantly improves the production efficiency.

[0042] As described above, the present application is an automatic device for preventing plate scratching and positioning, and all technical solutions the same as or similar to the present application shall be shown to fall within the protection scope of the present application.
