Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fruit detection equipment, in particular to a cherry sugar content nondestructive detection equipment based on multi-spectral imaging technology. BACKGROUND

[0002] Cherry sugar content is a key indicator of its quality. Traditional cherry sugar content detection mostly uses destructive sampling, such as juice extraction followed by chemical detection, which causes cherry loss and cannot quickly and batch detect individual cherries. Multi-spectral imaging technology gradually detects cherry sugar content without destroying the sample, but in actual application, cherries are easily shaken on the detection table, causing unstable illumination and affecting the accuracy of light signal acquisition, which is a common problem.

[0003] To solve the problem of cherry shaking affecting illumination, conventional methods use some fixing devices to fix cherries, reduce their shaking amplitude, make light more stably irradiate on cherries, and ensure that cherry information carried by light signals is more accurate, facilitating subsequent data processing and analysis.

[0004] However, conventional fixing methods can only limit cherry shaking from a physical level, but cannot dynamically and accurately adjust the light intensity irradiated on cherries according to the actual situation of cherry shaking. When cherries slightly shake due to external factors or their own state, fixed light intensity will cause deviation in light signal acquisition, thereby affecting subsequent cherry sugar content analysis results based on light signals, and it is difficult to meet the demand of high-precision detection.

[0005] Therefore, aiming at the existing problems, a cherry sugar content nondestructive detection equipment based on multi-spectral imaging technology is proposed. SUMMARY

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] like Figures 1 to 11 As shown, a non-destructive testing device for cherry sugar content based on multispectral imaging technology includes: a light source lamp 2, a base frame 1 surrounding the light source lamp 2, a power supply box 3 on one side of the light source lamp 2, a front frame 4 at the front end of the front of the base frame 1, a guide rail bracket 9 on the back of the top of the front frame 4, an illumination mirror 7 at the front end of the guide rail bracket 9, a material platform 25 at the middle of the front end of the guide rail bracket 9, a mounting block 8 on the back of the material platform 25, a material hole at the middle of the inner side of the material platform 25, and an amplitude sensor body 26 at the top of the material platform 25 near the guide rail bracket 9. A center vertical frame 12 is provided in the middle of the front of the front frame 4, and a sensing drive mechanism is vertically provided on the inner side of the center vertical frame 12. Auxiliary line mechanisms are provided on both sides of the material platform 25; A material-lifting mechanism is installed directly below the material platform 25; A demisting mechanism is installed on one side of the top material feeding mechanism; In this non-destructive testing equipment for cherry sugar content, the power supply box 3 first supplies power to the light source 2 inside the base frame 1. The light source 2, as the light source system of the multispectral imaging system, provides different types of light sources, such as visible and infrared light, which is then guided to the illumination mirror 7 at the front end of the guide rail bracket 9. The illumination mirror 7 is an optical system that, in conjunction with lenses, reflectors, and other components, adjusts the light before illuminating the cherries on the material platform 25. Then, the auxiliary line mechanisms on both sides of the amplitude sensor body 26 assist in light transmission and other related operations. Simultaneously, the sensing drive mechanism and other components inside the central vertical frame 12 work together to ensure that the positions of each component meet requirements during the detection process. The top-feeding mechanism can lift the cherries before and after detection, facilitating loading or unloading. The defogging mechanism removes fog that may affect light transmission and detection, ensuring a good detection environment. Subsequently, the light interacts with the cherries, and the light signals carrying information such as cherry sugar content are captured by sensors and external detectors. These light signals, based on the photoelectric effect, are decomposed into light of different wavelengths, corresponding to different spectral channels, by optical elements such as filters, falling within the scope of optical systems. Then, the data processing system acquires, stores, and analyzes the spectral data collected by the sensors. By extracting spectral absorption peaks, reflection peaks, and other characteristics, and based on the principle that different substances have different spectral characteristics in multispectral imaging technology, it achieves non-destructive detection of cherry sugar content.

The upper horizontal bevel gear 28 is located at the upper end of the inner side of the second belt 32. The upper vertical bevel gear 27 is located at the top of the upper horizontal bevel gear 28. An adapter plate is provided on the top of the upper vertical bevel gear 27, and the adapter plate is fixedly connected to the inner side of the middle vertical frame 12; The auxiliary line mechanism consists of a sliding sleeve 37, a sliding rod 36, a spring 35, a retaining plate 34, a rotating shaft 24, a driving gear 23, a rack 22, a polarizing mirror 13, a side panel 6, and a guide plate 5. The upper horizontal bevel gear 28 and the lower horizontal bevel gear 33 are both provided with a rotating shaft 24 at one end of the back of the middle vertical frame 12.

The sliding rod 36 is provided horizontally through the inner side of the sliding sleeve 37. The retaining plate 34 is provided at one end of the sliding rod 36. A spring 35 is also sleeved between the retaining plate 34 and the sliding sleeve 37. The guide plate 5 is provided on one side of the rack 22. The side panel 6 is provided on one side of the guide plate 5. The polarizing mirror 13 is provided inside the side panel 6.

The upper horizontal bevel gear 28, the lower horizontal bevel gear 33 and the rotating shaft 24 are integrated into one structure, and the rotation direction of the upper horizontal bevel gear 28 and the lower horizontal bevel gear 33 is the same as the rotation direction of the rotating shaft 24. When the cherries above the material platform 25 shake, the amplitude sensor body 26 converts the brief displacement signal generated by the cherries into digital signals and transmits them to the central control module. This module is pre-set and imports control commands into the servo motor 30. The servo motor 30 drives the lower vertical bevel gear 31 to rotate, the lower vertical bevel gear 31 drives the lower horizontal bevel gear 33 to rotate, the lower horizontal bevel gear 33 drives the second belt 32 to rotate, the second belt 32 drives the upper horizontal bevel gear 28 to rotate, and the upper vertical bevel gear 27 at the upper end of the upper horizontal bevel gear 28 follows its rotation. When the upper horizontal bevel gear 28 and the lower horizontal bevel gear 33 rotate, they drive their corresponding rotating shaft 24 to rotate. When the rotating shaft 24 rotates, the rotating shaft 24 drives the drive gear 23 to rotate, the drive gear 23 drives the rack 22 to move horizontally, and the rack 22 moves towards both sides of the material table 25. The rack 22 drives the sliding sleeve 37 to slide outside the sliding rod 36, and the spring 35 can help the sliding sleeve 37 move a certain distance and then return to its original position. The retaining plate 34 fixes the sliding rod 36 outside the middle vertical frame 12. When the guide plate 5 moves, the guide plate 5 drives the side panel 6 to move, and the side panel 6 drives the polarizing mirror 13 to move closer to both sides of the material stage 25. The polarizing mirror 13 can change its polarization direction, which can change the intensity of the polarized light passing through, thereby indirectly controlling the light intensity irradiating the cherry.

[0023] Example 2: Figures 1 to 11 As shown, the top material mechanism consists of an adapter wheel 29, an internal bearing 21, a threaded screw 20, a top material plate 19, a slider locking cylinder 15, a first belt 11, and a positioning shaft 10.

When the lower vertical bevel gear 31 rotates, it drives the adapter wheel 29 to rotate, which in turn drives the first belt 11 to rotate. The first belt 11 then drives the positioning shaft 10 to rotate, which in turn drives the threaded screw 20 to rotate. When the threaded screw 20 rotates, the slider locking cylinder 15 outside the threaded screw 20 moves vertically in conjunction with the built-in bearing 21. When the slider locking cylinder 15 moves upward, it drives the top plate 19 to move to the bottom of the material platform 25. The cherries that are stuck in the material hole inside the material platform 25 are then pushed out, achieving the purpose of automatic material discharge.

[0024] Example 3: Figures 1 to 11 As shown, the demisting mechanism consists of an air outlet pipe 14, a side strip 16, an air cylinder 17, a push rod 18, and an air inlet pipe 38.

The top edge of the air outlet pipe 14 is flush with the edge of the material platform 25. When the top plate 19 moves up and down, it drives the side strip 16 to move up and down. The side strip 16 drives the push rod 18 and the matching push plate to move up and down inside the air cylinder 17. The air inlet pipe 38 outside the air cylinder 17 draws in the gas, and the air cylinder 17 then discharges the gas to the outside of the material platform 25 through the air outlet pipe 14, so that the surface of the material platform 25 is always kept dry and prevents water stains on the outside of the cherries from affecting the light irradiation effect.
