Description

Technical Field

[0001] This patent relates to the field of apple quality inspection technology, specifically to an embedded chain-type rectangular guide rail apple internal and external quality inspection device. Background Technology

[0002] As residents' living standards improve, market demands for apple quality are becoming increasingly stringent, driving the development of apple quality inspection equipment towards higher precision. Apple quality inspection encompasses two main dimensions: external and internal. External quality inspection relies on visual technology to analyze appearance features, while internal quality inspection primarily depends on spectral technology. However, the accuracy of internal inspection fluctuates significantly due to factors such as positioning deviations in the conveyor mechanism, apple placement posture, and individual size differences. To address this, an embedded chain-type rectangular guide rail device for inspecting both internal and external apple quality has been developed. This device dynamically calibrates the spatial coordinates of the inspection unit based on the apple's center position, improving inspection accuracy by eliminating positional errors. It provides theoretical support and practical reference for building a more comprehensive apple quality inspection system and possesses significant practical application value.

[0014] The patent will now be described in detail with reference to the accompanying drawings.

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This device consists of three parts: a frame (1), an embedded chain-type rectangular guide rail conveyor mechanism (2), and an apple internal and external quality inspection box (3). The embedded chain-type rectangular guide rail conveyor mechanism (2) consists of an apple (201), an apple tray (202), an embedded chain track (203), a chain (204), a sprocket (205), a flat key (206), a stepper motor (207), a capacitive proximity sensor (208), and a side-bending chain plate (209). The apple internal and external quality inspection box (3) consists of an X-axis motion module (301), a controller (302), a Y-axis motion module (303), a spectrometer (304), a Z-axis motion module (305), and a support plate (306). 306), lighting lamp (307), housing (308), fixing block (309), halogen lamp (310), fiber optic probe (311), binocular camera (312), L-shaped connecting plate (313) and cross-shaped connecting plate (314); the X-axis motion module (301) is composed of servo motor (3011), motor flange (3012), coupling (3013), ball screw support seat (3014), ball screw (3015), guide rail (3016), stage (3017) and base (3018); the X-axis motion module (301), Y-axis motion module (303) and Z-axis motion module (305) have the same structure.

[0016] As shown in the attached figure, when the device is started, the device is controlled by the controller (302), and the lighting lamp (307) lights up accordingly. When an apple is placed randomly on an apple tray (202), the controller (302) will drive the stepper motor (207) to start rotating. The apple tray (202) on the traction chain (204) will slowly move into the apple internal and external quality inspection box (3). When the apple tray (202) reaches the location of the capacitive proximity sensor (208), the capacitive proximity sensor (208) will immediately capture the signal. After receiving the signal, the controller (302) will quickly instruct the stepper motor (207) to stop rotating and simultaneously turn on the binocular camera (312) to collect the image information of the apple. The controller (302) will accurately transmit this image data to the controller (302). The controller (302) will accurately analyze the image information of the apple based on the external image information of the apple and lock the world coordinates of the center position of the apple. Once the world coordinates of the center position of the apple are determined, the controller (302) will accurately drive the X-axis motion module (301), Y-axis motion module (303) and Z-axis motion module (305) to work together and intelligently and adaptively adjust the halogen lamp (310). The positions of the fiber optic probe (311) and binocular camera (312) are precisely positioned at the optimal detection point. After the positions are precisely adjusted, the binocular camera (312) is turned on to conduct a comprehensive analysis of the external quality of the apple, thus successfully completing the detection process of the external quality of the apple. Then, the lighting lamp (307) is turned off, and the spectrometer (304), halogen lamp (310) and fiber optic probe (311) are started in an orderly manner. At this time, the halogen lamp (310) stably emits near-infrared light, which is evenly irradiated on the outer surface of the apple. The fiber optic probe (311) keenly receives the near-infrared light reflected back from the apple skin and efficiently transmits these light signals to the spectrometer (304). The spectrometer (304) uses its high-precision spectral separation capability to finely separate the received reflected near-infrared light according to different wavelengths, deeply analyze the spectral characteristics, generate detailed spectral charts, and clearly present the intensity changes of light at each wavelength. Finally, these key analytical data are accurately transmitted to the controller (302). The controller performs in-depth analysis of the spectral data, thereby accurately completing the detection task of the internal quality of the apple.
