[0027] When this embodiment is actually used, the operator puts tennis balls of various colors mixed together into the collecting barrel 17, and starts the feeding assembly at the same time. The mixed tennis balls fall on the feeding assembly in order, and the feeding assembly conveys the tennis balls in order.

Tennis balls that do not match the color are conveyed to the material transmission assembly and then flow into a collecting barrel 17 below. The above steps are repeated to screen another color. In this process, the tennis balls can be classified and stored in a centralized manner according to color. At the same time, the process is carried out continuously, and the screening efficiency is higher.

Under the action of the vibration motor 36, the collecting barrel 17 can be driven to vibrate, thereby facilitating the tennis ball to fall from the collecting barrel 17.

[0032] The color recognition module includes an image processor 8 fixedly arranged on a fixed plate 16, and an image collector 24 is fixedly connected to the bottom of the fixed plate 16 below the image processor 8. The image collector 24 and the image processor 8 are connected through electrical signals, and the camera end of the image collector 24 corresponds to the limit slot 4 on the feeding belt 3.

[0033] The screening actuator includes a sensor controller 10 fixedly arranged on a fixed plate 16, a signal transmission rod 11 is arranged between the sensor controller 10 and the image processor 8, the bottom of the fixed plate 16 below the sensor controller 10 is fixedly connected to an electric slide rail 9, a sliding block 38 is slidably arranged in the electric slide rail 9, and the bottom of the sliding block 38 is fixedly connected to the screening rod 15.

[0034] The image collector 24 uses a high-resolution camera that can clearly capture the color features of the tennis ball, and then transmits the information to the image processor 8. The image processor 8 processes the captured image, including color analysis, feature extraction, etc., to achieve accurate recognition of the color of the tennis ball. After recognition, it is compared with the pre-set color, and then the signal is transmitted to the sensor controller 10. The sensor controller 10 controls the electric slide rail 9 to drive the sliding block 38 to move. Under the action of the screening rod 15, the tennis ball of the corresponding color is removed, and the tennis ball is pushed into the screening recovery box 27 on one side of the guide plate 28 to achieve centralized recovery.

[0038] Example 3, please refer to Figure 1-Figure 6The actual application scenario of the device is used in the operation scenario of color classification of tennis balls. When it is actually used, the operator places the mixed tennis balls in the collection barrel 17. Under the action of the driving motor 5, the feeding roller 6 drives the feeding belt 3 to move, and the vibration motor 36 drives the collection barrel 17 to vibrate. The tennis balls fall into the limit groove 4 on the feeding belt 3 in turn and are transported to one side. Under the action of the image collector 24, the color characteristics of the tennis balls are collected, and then under the action of the image processor 8, the collected color can be compared with the preset color. If the colors are the same, the sliding block 38 under the slide rail is controlled to move by the sensor controller 10. The sliding block 38 removes the tennis balls of the corresponding color through the screening rod 15 and sends them to the screening recovery box 27 at the corresponding position to achieve centralized collection.
