Description

Technical Field

[0001] The utility model relates to the technical field of machine vision, in particular to a fruit sorting device based on machine vision. Background Technique

[0002] Machine vision is a rapidly developing branch of artificial intelligence. Briefly speaking, machine vision is to use machines to replace human eyes for measurement and judgment. A machine vision system converts the target to be captured into an image signal through machine vision products (i.e., image acquisition devices, divided into CMOS and CCD types), transmits it to a dedicated image processing system, obtains the morphological information of the captured target, and converts it into a digital signal according to information such as pixel distribution, brightness, and color; the image system performs various operations on these signals to extract the features of the target, and then controls the actions of on-site devices according to the discrimination results. In the process of fruit sorting, fruits are mostly placed on a conveyor belt, and several workers stand on both sides of the conveyor belt to sort the fruits on the conveyor belt, which is troublesome and consumes a large amount of labor costs, and at the same time, the efficiency is low. Therefore, a fruit sorting device based on machine vision is designed. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a fruit sorting device based on machine vision, including: a sorting conveyor belt 1 with an overall flat shape, a sorting base 2 is connected in an array around the outer side of the sorting conveyor belt 1, the sorting base 2 is overall inclined, the inclination angle of the sorting base 2 is seventy degrees to eighty degrees, partition plates 3 are connected to the left and right sides of the upper surface of the sorting base 2, a controller 4 is connected to the left side of the front surface of the sorting conveyor belt 1, an incoming conveyor belt 5 is connected to the left side of the front surface of the sorting conveyor belt 1 and on the right side of the controller 4, the incoming conveyor belt 5 is communicated with the sorting conveyor belt 1 at the connection, slots are arranged in an array on the upper side of the front surface of the sorting conveyor belt 1, the lower ends of the slots are inclined, a baffle 6 is rotatably connected to the upper end inside the slots, an electric telescopic rod 7 is connected to the upper side of the front side of the sorting conveyor belt 1 and in front of the slots, a connecting plate 8 is rotatably connected between the lower side of the front surface of the baffle 6 and the telescopic end of the lower side of the electric telescopic rod 7, a downward-inclined guiding landslide 9 is arranged at the lower end of the opening of the front surface of the slots, a camera 10 is arranged on the upper surface of the sorting conveyor belt 1 and on the left side of the baffle 6, and the controller 4 is electrically connected to the sorting conveyor belt 1, the incoming conveyor belt 5, the electric telescopic rod 7, and the camera 10.

[0024] During use, set the position of each slot to discharge the size and color of the fruits through the controller 4. Then start the fruit sorting device based on machine vision. Next, pour the fruits onto the upper surface of the incoming conveyor belt 5. At this time, the fruits will be pushed by the incoming conveyor belt 5 to the upper end of the sorting base 2. Meanwhile, the partition plate 3 will separate the fruits. At the same time, the fruits will be driven to the right by the sorting conveyor belt 1. When passing under the camera 10, the camera 10 will transmit the captured image to the inside of the controller 4. Then the controller 4 will analyze the size and color of the fruits. When the size meets the current gear, the electric telescopic rod 7 will be activated. The electric telescopic rod 7 will pull the connecting plate 8 and the baffle 6. At this time, the slot position will be opened. Since the sorting base 2 is inclined as a whole, the fruits will slide out and fall into the inside of the guiding landslide 9 for classification. At the same time, the electric telescopic rod 7 extends to close the baffle 6 until the next qualified fruit arrives and then opens again.

[0025] As Figures 1-3 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, the inner side of the guiding landslide 9 inclines inward, and an anti-slip pad is arranged inside the guiding landslide 9.

[0026] Analyzing the above structure, it can be seen that the inner side of the guiding landslide 9 inclines inward and the anti-slip pad laid inside can slow down the speed of the fruits when sliding down, reduce the force when falling, and reduce damage.

[0027] As Figures 1-4 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, an anti-collision foam is attached to the inner side of the sorting conveyor belt 1.

[0028] Analyzing the above structure, it can be seen that the anti-collision foam attached to the inner side of the sorting conveyor belt 1 can reduce the damage caused when the fruits collide with the inner side of the sorting conveyor belt 1.

[0029] As Figures 1-4 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, a chamfer is provided at the rear opening of the connection between the sorting conveyor belt 1 and the incoming conveyor belt 5.

[0030] Analyzing the above structure, it can be seen that when the incoming conveyor belt 5 pushes the fruits into the inside of the sorting base 2, most of the fruits will still roll downward. At this time, the edge of the fruits will collide with the inner side of the opening of the sorting conveyor belt 1. At this time, the chamfer will play a guiding role to push the fruits in.

[0031] As Figures 1-3 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, the size of the rear opening of the guiding landslide 9 is larger than the size of the baffle 6.

[0032] Analyzing the above structure, it can be seen that the size of the opening at the rear end of the guiding landslide 9 is larger than that of the baffle 6, which facilitates the entry of fruits into the interior of the guiding landslide 9.

[0033] As Figures 1-3 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, chamfers are provided on both the left and right sides of the rear end of the slotted part and the rear end of the baffle 6.

[0034] Analyzing the above structure, it can be seen that the chamfers on both the left and right sides of the rear end of the baffle 6 can play a guiding role to facilitate the reset of the baffle 6, while the chamfers at the opening of the rear end of the slotted part can play a role in pre-guiding, that is, when the fruit reaches the chamfer position at the rear side of the slotted part, it will slide downward in advance.

[0035] As Figures 1-2 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, an indicator light 21 is connected to the middle of the upper surface of the camera 10, and the indicator light 21 is electrically connected to the controller 4.

[0036] Analyzing the above structure, it can be seen that when the detection determines that it meets the size and color of the current position, the indicator light 21 will light up to give a reminder.
