[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0025] like Figure 1 As shown, this utility model provides an integrated X-ray vision inspection device, including a conveyor belt 1, an infrared light detection component, a visible light detection component, an X-ray detection component, a rejection component 7, and a reflector 6. The X-ray detection component, the visible light detection component, and the infrared light detection component can all operate independently or be installed in combination.

[0026] The material to be tested, 5, is placed on conveyor belt 1. The feeding end of conveyor belt 1 is the input end, and the discharging end of conveyor belt 1 is the output end. Material 5 leaves conveyor belt 1 from the output end. Conveyor belt 1 is driven by a motor.

[0027] The infrared light detection component includes an infrared camera 21 and two infrared lamps 22. The infrared light detection component is located above the position where material 5 leaves conveyor belt 1. It is positioned above the visible light detection component, and the vertical projections of the infrared and visible light detection components overlap, allowing for both visible and infrared detection at almost the same location. The two infrared lamps 22 are located on either side of a first straight line, with their extension directions forming an acute angle with the first straight line and pointing towards material 5, uniformly illuminating it. When material 5 enters the infrared light detection component, the infrared camera 21 acquires an image of material 5. The infrared lamps 22 illuminate material 5, providing the detection environment for the infrared light detection component.

[0028] The visible light detection component includes a visible light camera 31 and three visible light lamps 32, located above the position where material 5 leaves conveyor belt 1. Two visible light lamps 32 are located on either side of a first straight line, with their extension directions forming an acute angle with the first straight line and pointing towards material 5; one visible light lamp 32 is located below the position where material 5 leaves conveyor belt 1, uniformly illuminating material 5. The visible light lamps 32 can be LEDs, with a color different from that of material 5. When material 5 enters the visible light detection component, the visible light camera 31 acquires an image of material 5. The visible light lamps 32 illuminate material 5; the visible light lamp 32 located below material 5 serves as a background light (RGB tri-color LED), providing a background with maximum color difference from material 5, typically blue, but can be switched to red or green, providing a detection environment for the visible light detection component.

[0029] The X-ray detection assembly includes an X-ray source 41 and an X-ray detector 42. The X-ray source 41 is located above the conveyor belt 1, and the X-ray detector 42 is disposed on the surface of the conveyor belt 1. The material to be detected 5 is located between the X-ray source 41 and the X-ray detector 42. The X-ray source 41 emits X-rays, which penetrate the material 5 to detect medium- and high-density foreign objects. The X-ray detector 42 obtains a grayscale image of the X-rays after they have penetrated the material 5.

[0030] The rejection assembly 7 includes multiple air nozzles and an air-blowing control valve. The air-blowing control valve is installed on the air nozzles, and the multiple air nozzles are arranged along the falling trajectory of the material 5. The rejection assembly 7 is located outside the output end of the conveyor belt 1. The multiple air nozzles perform point-to-point rejection of the material 5. As the material 5 flies out in a parabolic trajectory, air-blowing interference is applied, causing the trajectory of defective products to change and enter the lower defective product box. Qualified products are not affected by air-blowing interference and will fly directly out to the qualified product outlet, thereby achieving the purpose of separating good and bad materials.

[0031] The reflector 6 is located on one side of the infrared camera 21 and the visible light camera 31, and the reflector 6 is tilted at an angle of 45°. The line connecting the material to be tested to the reflector 6 is the first straight line, the line connecting the infrared camera 21 to the reflector 6 is the second straight line, and the line connecting the visible light camera 31 to the reflector 6 is the third straight line. When the material to be tested is in the first state, the intersection of the first and second straight lines is located on the surface of the reflector 6. When the material to be tested is in the second state, the intersection of the first and third straight lines is located on the surface of the reflector 6.

[0032] This invention integrates multiple detection methods, including X-ray, visible light, and infrared, to simultaneously detect external defects, internal defects, and foreign objects in raw materials. It achieves: external defect detection (visible light): including defects such as shape, size, and color; internal defect detection (infrared): detecting defects such as internal mold and insect infestation; and foreign object detection (X-ray): detecting foreign objects originating from the raw material itself or external sources, including fruit shells, leaves, glass, pebbles, and metal fragments. This effectively reduces material loss and lowers raw material testing costs.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
