Description

Technical Field

[0001] The invention relates to the technical field of fruit detection, and in particular to a fruit quality detection device. Background Art

[0002] Fruit is an edible fruit of a plant, which is rich in vitamins. Common fruits include apples, pears, tangerines, oranges, bananas, etc. In order to ensure that the fruits supplied to people are intact, fruits will undergo certain inspections before they are put on the market to reduce the probability of people buying bad fruits.

[0003] At present, nondestructive testing devices are needed for nondestructive testing of small round fruits such as apples, tangerines, and oranges (hereinafter referred to as fruits). Most of the nondestructive testing devices on the market are in the form of assembly lines, mainly composed of multiple sets of conveyor belts, spectral detection components, and fruit trays. When in use, the fruit is placed on the fruit tray, and then the fruit tray is placed on the conveyor belt. When the fruit enters the spectral detection component, its internal full projection spectrum will detect the fruit, so as to obtain the internal quality index of the fruit. Then the image acquisition component in the spectral detection component will capture the image of the appearance of the fruit to obtain the external quality index of the fruit, and then the defective fruit will be quickly detected through the detection and grading algorithm, and then transmitted to the next sorting conveyor belt through the conveyor belt, waiting for manual unloading.

[0004] However, when the above-mentioned fruit non-destructive testing device is testing fruits, the fruits are placed statically in the fruit tray. When the fruit tray with the fruits passes through the spectral detection component, the spectral detection component can only collect and detect one angle of the fruit. If the part of the fruit not irradiated by the spectral detection component is damaged, the spectral detection component cannot detect that there is a problem with the fruit, which will cause bad fruits to pass the test, thus affecting the inspection quality of the fruit. Summary of the invention

[0005] The embodiment of the present application provides a fruit quality detection device, which solves the problem that in the prior art solution, fruits are placed statically in a fruit tray. When the fruit tray with fruits passes through the spectral detection component, the spectral detection component can only collect and detect one angle of the fruit. If the part of the fruit that is not irradiated by the spectral detection component is damaged, the spectral detection component cannot detect that there is a problem with the fruit, which will cause bad fruits to pass the detection, thus affecting the technical problem of the fruit detection quality.

[0008] The fruit support mechanism comprises a limiting seat, a fruit support for placing fruits, and a gear arranged around the limiting seat; the fruit support is arranged on the limiting seat; the limiting seat is sleeved on the supporting block; the rotating device is transmission-connected to the gear;

[0009] The rotating device includes a bending block, a first driving device for driving the bending block to move, and a rack meshingly connected to the gear; the bending block is arranged on the driving end of the first driving device; the first driving device is installed on the spectrum detection component; the rack is arranged on the bending block; when the driving end of the first driving device is extended and retracted, the bending block will slide back and forth along the support frame.

[0012] A further technical solution is: the first driving device is a cylinder.

[0013] A further technical solution is: the second driving device is a motor.

[0014] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0015] 1. Due to the arrangement of the support frame, the fruit support mechanism, the conveyor belt conveying mechanism, the support block, the rotating device and the spectrum detection component, when it is necessary to detect the quality of the fruit, firstly, a fruit support mechanism is sleeved on the support block at the top of the entrance end of the conveyor belt conveying mechanism, and then the fruit to be detected is placed in the fruit-carrying fruit tray. At this time, the conveyor belt conveying mechanism starts to work, so that the fruit support mechanism is transported to the spectrum detection component. When the fruit-carrying fruit tray carries the fruit to the spectrum detection component, the conveyor belt conveying mechanism stops working. At this time, the rotating device in the spectrum detection component starts to work, so that the driving end of the first driving device in the rotating device extends out. At this time, the bending block will move with the rack toward the gear position set on the limit seat. When the rack contacts the gear and moves again, the gear will drive the limit seat to rotate on the support block, thereby driving the placed The fruits in the fruit tray rotate together, and the detection spectrometer and the optical fiber receiver in the spectrum detection component start working at this time, so that the fruits placed in the fruit tray can be subjected to multi-angle quality detection. After the quality detection of the fruits placed in the fruit tray is completed, the driving end of the first driving device in the rotating device is retracted, and the conveyor belt conveying mechanism starts working again, so that the fruit tray mechanism with the detected fruits is moved out of the spectrum detection component, and the fruit tray mechanism placed on the adjacent support block is moved to the spectrum detection component with the fruits to be detected, and the above operation is repeated, so that the quality of the next group of fruits placed in the fruit tray can be detected. The whole operation process is simple and reliable. At the same time, through the cooperation between the fruit tray mechanism itself and the rotating device, the fruits themselves can be detected at multiple angles, thereby ensuring the detection quality of the fruits.

[0016] 2. Due to the arrangement of the conveyor belt, rotating rollers and the second driving device, one group of rotating rollers is driven to rotate by the output shaft of the second driving device. Since the conveyor belt is wound around the two groups of rotating rollers, when the rotating rollers rotate, the two groups of rotating rollers and the conveyor belt can be driven to rotate together, thereby enabling the conveyor belt to drive the support blocks arranged on the conveyor belt to move together.

[0017] 3. Since a plurality of arc-shaped openings arranged in a circular array are provided on the fruit tray, when the detection spectrometer in the spectrum detection component projects light onto the fruit, a larger portion of the fruit placed in the fruit tray can be illuminated.

DETAILED DESCRIPTION

[0023] The embodiment of the present application provides a fruit quality detection device, which solves the problem that in the prior art solution, fruits are placed statically in a fruit tray. When the fruit tray with fruits passes through the spectral detection component, the spectral detection component can only collect and detect one angle of the fruit. If the part of the fruit that is not irradiated by the spectral detection component is damaged, the spectral detection component cannot detect that there is a problem with the fruit, which will cause bad fruits to pass the detection, thus affecting the technical problem of the fruit detection quality.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The fruit support 22 is arranged on the limiting seat 21. The limiting seat 21 is sleeved on the support block 4. The rotating device 5 is transmission-connected to the gear 23.

[0028] The rotating device 5 includes a bending block 51, a first driving device 52 for driving the bending block 51 to move, and a rack 53 meshed with the gear 23. The bending block 51 is arranged on the driving end of the first driving device 52. The first driving device 52 is installed on the spectrum detection component 6. The rack 53 is arranged on the bending block 51. When the driving end of the first driving device 52 is extended and retracted, the bending block 51 will slide back and forth along the support frame 1.

[0029] The conveyor belt conveying mechanism 3 is fixedly mounted on the support frame 1. A plurality of groups of support blocks 4 arranged in a linear array are fixedly arranged around the conveyor belt conveying mechanism 3.

The rack 53 is fixedly connected to the bending block 51. When the driving end of the first driving device 52 is extended and retracted, the bending block 51 will slide back and forth along the support frame 1.

[0030] Due to the arrangement of the support frame 1, the fruit supporting mechanism 2, the conveyor belt conveying mechanism 3, the support block 4, the rotating device 5 and the spectrum detection component 6, when it is necessary to detect the quality of the fruit, firstly, the fruit supporting mechanism 2 is sleeved on the support block 4 at the top of the entrance end of the conveyor belt conveying mechanism 3, and then the fruit to be detected is placed in the fruit-carrying tray 22, and the conveyor belt conveying mechanism 3 starts to work at this time, so that the fruit supporting mechanism 2 is transported to the spectrum detection component 6, when the fruit-carrying tray 22 transports the fruit to the spectrum detection component 6, the conveyor belt conveying mechanism 3 stops working, and the rotating device 5 in the spectrum detection component 6 starts to work at this time, so that the driving end of the first driving device 52 in the rotating device 5 extends out, and at this time the bending block 51 will move with the rack 53 toward the position of the gear 23 set on the limit seat 21, and when the rack 53 contacts the gear 23 and moves again, the gear 23 will drive the limit seat 21 to rotate on the support block 4 , and then the fruits placed in the fruit tray 22 can be driven to rotate together. At this time, the detection spectrometer and the optical fiber receiver in the spectrum detection component 6 start working, and the fruits placed in the fruit tray 22 can be subjected to multi-angle quality detection. After the quality detection of the fruits placed in the fruit tray 22 is completed, the driving end of the first driving device 52 in the rotating device 5 is retracted, and the conveyor belt conveying mechanism 3 starts working again, so that the fruit tray mechanism 2 with the detected fruits is moved out of the spectrum detection component 6, and the fruit tray mechanism 2 placed on the adjacent support block 4 is moved to the spectrum detection component 6 with the fruits to be detected, and the above operation is repeated, so that the quality of the next group of fruits placed in the fruit tray 22 can be detected.
