Description

Technical Field

[0001] The utility model relates to the field of sorting equipment, in particular to a machine vision material sorting device. Background Art

[0002] Machine vision is the ability of machines to simulate the human visual system, capture image data of materials through image sensors, and then use special image processing algorithms to analyze these data to extract the characteristic information of the materials. Material sorting refers to the process of separating different types of materials from the mixed material flow and placing them accurately in designated locations according to preset rules or instructions.

[0003] The material sorting device of machine vision is generally composed of a conveyor belt, an image sensor and a telescopic cylinder. The material is transported by the conveyor belt, and the image sensor set on the surface of the conveyor belt identifies the material type. Then the telescopic cylinder set on one side pushes the material to the designated position to complete the sorting operation. In the process of transporting materials using the conveyor belt, when the telescopic cylinder applies thrust to the material, the static friction between the material and the conveyor belt will be converted into dynamic friction, affecting the stability of the material on the conveyor belt. At the same time, since the conveyor belt itself is in motion, when the cylinder applies thrust to the material, it may cause the material to shift on the conveyor belt, thereby affecting the mismatch between the material and the discharge port on one side of the conveyor belt, resulting in the material failing to accurately reach the predetermined position during the sorting operation, thereby reducing the material sorting efficiency.

[0004] Therefore, it is necessary to provide a new machine vision material sorting device to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a material sorting device based on machine vision.

[0006] The machine vision material sorting device provided by the utility model includes a transmission device for transporting materials, a plurality of driving components are arranged on one side of the transmission device, a push plate is arranged on the output end of the driving component, a mounting plate is fixedly arranged on one end of the push plate, a mounting groove is opened on one side of the mounting plate, and a movable plate is arranged inside the mounting groove, the movable plate is connected to the inner side of the mounting groove through a plurality of elastic parts, and a plurality of protrusions are arranged on the side of the movable plate away from the mounting groove.

[0007] Preferably, the driving component includes a support frame and a telescopic cylinder, the bottom of the telescopic cylinder is fixedly connected to the top of the support frame, and one side of the push plate is fixedly connected to the output end of the telescopic cylinder, and one side of the transmission device is provided with a plurality of grooves for the push plate to move.

[0008] Preferably, a fixed plate for unloading materials is provided at the bottom of the discharge port, and a plurality of movable rollers are provided on the surface of the fixed plate.

[0009] Preferably, a collecting box for collecting materials is provided at the bottom of the fixed plate.

[0010] Preferably, a plurality of image sensors for identifying materials are provided on the top of the transmission device.

[0011] Preferably, the elastic member is a spring, one end of the spring is fixedly connected to one side of the movable plate, and the other end of the spring is fixedly connected to the inner side of the mounting groove.

[0012] Preferably, a plurality of discharge ports are provided on a side of the transmission device away from the push plate.

[0013] Compared with the related art, the machine vision material sorting device provided by the utility model has the following beneficial effects:

[0014] 1. When sorting materials, the push plate is driven by the driving component to move toward the material. When in contact with the material, the movable plate and the mounting plate set at one end can block the edge of the material, improve the stability of the material, and prevent the material from shifting due to the push of the driving component when the transmission equipment is moving. The setting of the movable plate can help the material maintain a stable posture and position, ensuring that the material can match the discharge port, thereby improving the sorting efficiency of the material to a certain extent.

[0015] 2. Because the movable plate is set in the installation groove and is connected to the inner side of the installation groove through an elastic member, when the side of the material contacts the movable plate, it will push the movable plate to move inside the installation groove and squeeze the elastic member. Under the elastic action of the elastic member, it can absorb and disperse the energy generated by the material when it hits the movable plate, thereby protecting the objects and extending the service life of the movable plate.

[0016] 3. By setting a plurality of raised blocks on one side of the movable plate, the contact area with the material can be increased, thereby increasing the friction between the movable plate and the material, and further improving the stability of the material.

[0026] A fixed plate 9 for unloading is provided at the bottom of the discharge port 14, and a plurality of movable rollers 10 are provided on the surface of the fixed plate 9. A collecting box 11 for collecting materials is provided at the bottom of the fixed plate 9. A plurality of image sensors 12 for identifying materials are provided at the top of the transmission device 1. The elastic member is a spring 13. One end of the spring 13 is fixedly connected to one side of the movable plate 5, and the other end of the spring 13 is fixedly connected to the inner side of the mounting groove 4. A plurality of discharge ports 14 are provided on the side of the transmission device 1 away from the pushing plate 2.

The material only slides to the inside of the collecting box 11 set at the bottom of the fixed plate 9. During the sliding process of the material, the plurality of movable rollers 10 set on the surface of the fixed plate 9 can make the material slide more smoothly, thereby preventing the material from being stuck on the surface of the fixed plate 9 due to excessive friction.

[0027] The working principle provided by the utility model is as follows: the material is placed on the top of the transmission device 1, and the material is transported to the bottom of the image sensor 12 through the transmission device 1. The image sensor 12 identifies the material type. When the material to be sorted is detected, the telescopic cylinder 8 is started, and the push plate 2 is driven to move toward the material direction by the telescopic cylinder 8. When the side of the push plate 2 contacts the material, the movable plate 5 set at one end of the push plate 2 blocks the edge of the material to improve the stability of the material. At the same time, the multiple raised blocks 6 set on one side of the movable plate 5 can increase the contact area with the material, thereby enhancing the friction between the material and the movable plate 5, further improving the stability of the material, and the setting of the movable plate 5 can help the material maintain a stable posture and position, ensuring that the material can match the discharge port 14;

[0028] Because the movable plate 5 is arranged inside the installation groove 4, when the material contacts the movable plate 5, it will push the movable plate 5 to move inside the installation groove 4 and squeeze the spring 13. Under the elastic action of the spring 13, the energy generated by the material when it hits the movable plate 5 can be absorbed and dispersed, thereby protecting the object and extending the service life of the movable plate 5.
