Due to the differences in the arrival positions of the conveying mechanism and the differences in the placement and size of the apples, the accuracy of the internal quality detection of apples has a large deviation. An adaptive adjustment device for the position of internal and external quality detection of apples can adaptively adjust the position of the detection device according to the center position of the apple to improve the accuracy of internal and external quality detection of apples, which provides a certain theoretical basis for the apple quality detection system and has certain practical significance.

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

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The device is composed of a frame (1), an adaptive adjustment detection box (2), and a conveying mechanism (3), wherein the adaptive adjustment detection box (2) is composed of a housing (201), a through-beam sensor (202), a binocular image collector (203), a spectrometer (204), a halogen tungsten lamp (205), a reflection probe (206), an illuminating lamp (207), a first motor drive module (208), a controller (209), a through-beam sensor base (2010), a second motor drive module (2011), and a third motor drive module (2012). The motor drive module (208) is composed of a servo motor (2081), a motor flange (2082), a coupling (2083), a slide table (2084), a loading platform (2085) and a ball screw (2086); the first motor drive module (208), the second motor drive module (2011) and the third motor drive module (2012) are completely identical in structure; the conveying mechanism (3) is composed of a fruit tray (301), an active double-row sprocket wheel (302), a double-row chain (303), a driven double-row sprocket wheel (304) and a fruit tray fixing frame (305).

[0016] As shown in the accompanying drawings, the device is operated by the controller (209), the lighting (207) is turned on, and an apple is randomly placed on the fruit plate (301). The controller (209) drives the active double-row sprocket (302) to rotate, driving the fruit plate (301) on the double-row chain (303) to enter the adaptive adjustment detection box (2). When the fruit plate (301) moves to the middle of the opposing sensor (202), the opposing sensor (202) receives a signal, and the controller (209) controls the active double-row sprocket (302) to stop rotating, starts the binocular image collector (203) to collect apple image information, and transmits the collected apple image information to the controller (209). The controller (209) completes the apple external quality detection by performing external quality analysis on the apple external image information. At the same time, the controller (209) obtains the coordinate information of the apple center position by analyzing the apple image information. After the coordinate information of the apple center position is determined, the controller (209) drives the first motor drive module (208), the second motor drive module (2011) and the third motor drive module (2012) to move according to the coordinate information of the center position of the apple, and adaptively adjusts the position of the halogen tungsten lamp (205) and the reflection probe (206) to make them in the best detection position. After the position adjustment is completed, the lighting lamp (207) is turned off, and the spectrometer (204), the halogen tungsten lamp (205) and the reflection probe (206) are started. The halogen tungsten lamp (205) emits near-infrared light to illuminate the outer surface of the apple. The reflection probe (206) receives the near-infrared light reflected from the surface of the apple and then transmits it to the spectrometer (204). The spectrometer (204) receives the light transmitted back by the reflection probe, separates the light of different wavelengths, analyzes the reflected light, and provides a detailed spectrum diagram showing the light intensity of various wavelengths. The analysis data is transmitted to the controller (209). The controller analyzes the spectrum data to complete the internal quality inspection of the apple.
