Description

Technical Field

[0001] The invention belongs to the technical field of material sorting, and specifically refers to an intelligent visual detection material sorting system. Background Art

[0002] In agricultural production, material sorting is an important link. Traditional material sorting mainly relies on manual labor, which is inefficient and prone to errors. With the development of technology, the use of machine vision for material sorting has gradually become a trend. Machine vision can quickly and accurately identify material characteristics and realize automatic sorting. Among them, it is necessary to grade fruits before they are sold or processed, which helps to achieve the best pricing for high-quality products and meet processing needs. At present, the grading process mainly relies on agricultural personnel to evaluate and sort the fruits according to their weight, diameter and other characteristics. However, this method that relies on personal experience is subjective and inefficient.

[0003] In order to solve the above-mentioned problems, taking apples as an example, the patent with publication number CN117840072A discloses a customizable spherical fruit and vegetable quality non-destructive sorting and suitable processing system, including a material transmission module for transmitting, identifying and locating fruits and vegetables; a machine vision detection module for capturing surface information of fruits and vegetables and detecting fruit shape index, fruit surface defects, etc.; a visible near-infrared spectrum detection module for obtaining spectral information of fruits and vegetables and detecting indicators such as sugar content, acidity, and maturity; an information management module installed in a computer for recording, processing and feedback of information of the material transmission module, the machine vision detection module, the visible near-infrared spectrum detection module and the sorting module; a sorting module for transporting fruits and vegetables to different functional areas for processing according to data from different modules and pre-customized sorting standards.

[0037] In this embodiment, the piston fixing seat 103 is fixedly connected to the sorting frame body 300 and is located in the inner cavity of the transport belt 303. The weight bearing seat 100 is arranged directly below the bearing groove 304. The other end of the hydraulic pipe 104 is fixedly connected to the hydraulic rod body 105, and is configured to drive the hydraulic rod body 105 to extend and retract. The sorting fixing frame 122 is fixedly connected to the sorting frame body 300. The stepping motor shaft 115 passes through the sorting fixing frame 122. The push rod 120 passes through the sorting fixing frame 122. The sorting push piece 121 is located on one side of the bearing groove 304.

When the weight of each piston cylinder 101 reaches the set value, the contact groove 108 on the paddle body 106 is connected with the contact 109 under the push of the hydraulic rod body 105, and the lower section 112 of the wire is connected with the upper section 111 of the wire to realize the sorting function.

The low-quality fruit and vegetable pusher 205 will push the fruits and vegetables on the bearing groove 304 into the low-quality defective fruit and vegetable storage box 308, thereby realizing the special sorting function of low-quality defective fruits with large size and low moisture.

[0038] When in use, first, the roller driving stepper motor 301 is started, and the fruits and vegetables to be sorted are placed on the conveying belt 303, and the fruits and vegetables roll into the bearing groove 304. When the roller driving stepper motor 301 drives the fruits and vegetables on the conveying belt 303 to pass over the piston cylinder 101 in an orderly manner through the roller body 302, the fruits and vegetables will squeeze the upper end of the piston cylinder 101 through the weight bearing seat 100, and the hydraulic oil in the piston cylinder 101 will be compressed. The hydraulic oil drives the hydraulic rod body 105 to extend through the hydraulic pipe 104, and the hydraulic rod body 105 will drive the paddle body 106 to rotate around the shaft body 107, so that the contact groove 108 on the paddle body 106 contacts the contact head 109.

The push rod 120 reciprocates along the through hole on the sorting fixing frame 122, and then the push rod 120 pushes the fruits and vegetables in the upper bearing groove 304 of the weight bearing seat 100 into the corresponding sorting storage and transportation box 307 through the sorting push piece 121, so that the grading and sorting function of fruits and vegetables of different weights can be realized only through the mechanical structure;

[0039] When the roller drives the stepper motor 301 through the roller body 302 to drive the fruits and vegetables on the conveying belt 303 to pass over the piston cylinder 101 in an orderly manner, and the weight of the fruits and vegetables on the bearing groove 304 is light, the hydraulic oil cannot push the contact groove 108 on the paddle body 106 to contact the contact 109 through the hydraulic pipe 104 and the hydraulic rod body 105, and the roller drives the stepper motor 301 to continue to drive the fruits and vegetables on the conveying belt 303 to pass over the next group of piston cylinders 101 in an orderly manner through the roller body 302. When the weight reaches the set value, the same sorting function as above can be achieved;

[0040] Finally, the fruits and vegetables after three-level grading and sorting continue to pass under the visual inspection camera 200 driven by the conveyor belt 303. The visual inspection camera 200 can identify the fruits and vegetables that are larger than the set fruit diameter. Since they are larger in size but have not been sorted before, they are judged as low-quality defective fruits with large fruit diameter and low moisture content. Then, the visual inspection camera 200 inputs a signal to the controller 202, and the controller 202 controls the electric telescopic rod body 203, and then the telescopic rod shaft body 204 pushes the defective fruits and vegetables on one side of the low-quality fruit and vegetable push piece 205 into the low-quality defective fruit and vegetable storage box 308, thereby realizing the non-destructive intelligent detection and sorting function of low-quality defective fruits with large size and low moisture content.
