The frame 1 is fixed on the ground and located above the vehicle conveyor belt 2. A camera device and a jetting device 5 are provided on the frame 1. The camera device is used to take pictures of different angles of the vehicle, and the jetting device 5 is used to blow the scanning area of the vehicle.

[0027] In this embodiment, a frame 1 is provided above the vehicle conveyor belt 2. By installing the camera device on the frame 1, when the vehicle is conveyed past, the vehicle is automatically photographed by the camera device without manual photography; at the same time, the scanning area is blown by the jetting device 5, which can remove stains and water stains and ensure the effectiveness of scanning and recognition. The entire inspection process does not require manual participation, effectively reducing the labor cost.

[0028] In the vehicle automatic inspection device of this embodiment, the vehicle conveyor belt 2 is used to convey the vehicles to be inspected and leaving the factory. When in use, multiple vehicles will pass through the vehicle conveyor belt 2 in sequence. The entire vehicle automatic inspection device is installed in the inspection room to prevent the external environment, such as rain, from affecting vehicle inspection. The frame 1 is installed across both sides of the vehicle conveyor belt 2 to facilitate the arrangement of the imaging devices. The frame 1 can be directly fixedly connected to the ground or indirectly fixedly connected to the ground through the wall. The vehicle's code scanning area is selected according to the actual situation. For example, it is located at the front windshield of the vehicle and can scan the vehicle's VIN code, that is, the vehicle identification number, and compare the scanned information with the information in the vehicle production system to ensure the accuracy of the shooting of each vehicle. The jet device 5 is aligned with the vehicle's code scanning area and uses high-pressure gas to clean water stains and stains when the vehicle passes by, ensuring that the scanned information can be recognized. The imaging devices in this embodiment may include multiple cameras 3. Each camera 3 can take photos of the vehicle from different angles for license plate inspection, and can also take photos of the vehicle's code scanning area and perform code scanning and identification.

[0029] Reference Figure 1 and Figure 2 , in this embodiment, the imaging devices include a control cabinet 4 and multiple cameras 3. Each camera 3 is electrically connected to the control cabinet 4, and each camera 3 is respectively installed at different positions on the frame 1. Specifically, there are five cameras 3, which are respectively installed at the left front, right rear, front center, rear center, and middle positions corresponding to the vehicle shooting positions on the frame 1. The height of the cameras 3 can be higher than the height of the vehicle top. When the vehicle enters the shooting position, the vehicle photos or video information required for license plate inspection can be obtained through the five cameras 3 at corresponding positions, and the obtained information can also be transmitted to the public security system server through the Internet to achieve automatic vehicle inspection. It should be noted that the functions of the cameras 3 include but are not limited to taking photos, recording videos, and OCR identifying the vehicle's VIN code.

[0030] Reference Figure 3 , in this embodiment, the jet device 5 includes a bracket, a high-pressure gas source, and a high-pressure air pipe 504. The bracket is connected to the frame 1. One end of the high-pressure air pipe 504 is connected to the high-pressure gas source, and the other end is fixedly installed on the bracket. The high-pressure air pipe 504 is connected to the high-pressure gas source to blow the vehicle's code scanning area to remove water stains and stains, ensuring accurate information recognition after shooting.

The third connecting portion 503 is hinged to the second connecting portion 502. The air outlet end of the high-pressure air pipe 504 is fixed to the third connecting portion 503. Specifically, the first connecting portion 501 is constructed as a rectangular structure, and a connecting rod 508 is obliquely arranged inside the rectangular structure to ensure the stability of the structure. The middle part of the rectangular structure is slidably connected to the top of the frame 1. This sliding connection enables the first connecting portion 501 to slide relative to the frame 1 to adjust its position to meet the requirements of different vehicles. After the adjustment is completed, the position of the first connecting portion 501 can also be fixed for the inspection of vehicles in the same batch. There are many ways of sliding connection. For example, a slide rail and slider structure can be adopted, with the slide rail fixed to the frame 1, the slider fixed to the first connecting portion 501, and the slide rail slidingly connected to the slider bracket. Or, as in this embodiment, a guide groove 506 is provided at the top of the rectangular structure, and it is slidably connected to the top cross beam of the frame 1 through the guide groove 506. A U-shaped connecting member 507 is also provided to fix the guide groove 506 and the top of the frame 1. The lower end of the first connecting portion is hinged to the second connecting portion 502, and the lower end of the second connecting portion 502 is hinged to the third connecting portion 503, which is convenient for adjusting the position of the high-pressure air pipe 504. The air outlet end of the high-pressure air pipe 504 is connected with a nozzle 505. The high-pressure air pipe 504 is fixed to the third connecting portion 503 through a fixing member 509. In other embodiments, the high-pressure air pipe 504 can also be fixed to the third connecting portion 503 through tapes, cable ties, etc., so that the nozzle 505 of the high-pressure air pipe 504 extends from the tail of the third connecting portion 503, which is convenient for adjusting the air jet position.

[0032] Preferably, in this embodiment, the sliding direction of the first connecting portion 501 relative to the frame 1 is perpendicular to the moving direction of the vehicle conveyor belt 2. This enables the jet device 5 to adjust its position in the direction perpendicular to the vehicle conveying direction, and the adjustable jet range covers the entire transverse range of the vehicle conveyor belt 2, which is convenient for adjusting the jet device 5 to meet the inspection requirements of different vehicle models.

[0033] Preferably, in this embodiment, the axis of the hinge rotation center between the second connecting portion 502 and the first connecting portion 501 is vertically arranged, and the axis of the hinge rotation center between the third connecting portion 503 and the second connecting portion 502 is horizontally arranged. Through the hinge between the first connecting portion 501 and the second connecting portion 502, the second connecting portion 502 can rotate in the horizontal plane to adjust its position; through the hinge between the second connecting portion 502 and the third connecting portion 503, the third connecting portion 503 can rotate in the vertical plane to adjust its position, which is convenient for adjusting the jet position of the high-pressure air pipe 504.

[0034] Reference Figure 1, in this embodiment, the vehicle automatic inspection device further includes a position sensor 6, which is installed on the frame 1 and corresponds to the shooting position of the vehicle. Specifically, multiple groups of position sensors 6 can be set to improve the detection accuracy.
