DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings, and the structure and principle of the present invention are very clear to people in the field. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] See also Figure 1 and Figure 2In a preferred embodiment, the present invention is an intelligent visual cocoon selection device, including a visual camera, a visual processor, a mechanical actuator, a negative pressure suction mechanism, a raw material turning mechanism, a transparent conveyor belt, a strong light and an illumination light, and the mechanical actuator is a manipulator.

[0025] The device has two working positions. The raw cocoons move in translation on the conveyor belt. A visual camera is installed on each side of the conveyor belt at the first working position. The two visual cameras are installed diagonally. The height, angle and position of the camera can be adjusted. The visual camera and the visual processor can detect defects in five directions of the raw cocoons. A strong light is installed under the transparent conveyor belt. The strong light transmits light upward to find the inner printed cocoon. The coordinates of the detected defective cocoons are sent to the mechanical actuator. The three-dimensional manipulator tracks the top of the defective cocoon, turns on the negative pressure switch, and sucks the defective cocoon away. After the first inspection, the raw cocoon must pass through a raw material flipping mechanism. This mechanism uses a combination of mechanical rotation and pneumatic rotation. After the raw cocoon is flipped 180°, it enters the second inspection. The second inspection, structure, method and principle are the same as the first.

[0026] The raw cocoon conveyor belt is connected to the system host by an encoder. The cocoon selection speed can be automatically adjusted according to different raw cocoons. If there is leakage in the inspected cocoons, the conveyor belt will slow down or stop until all the cocoons are sucked and then start again.
