[0016] Reference Figure 1-2As shown, a vision-based automated sorting and traying device includes a product conveyor line 1. A vision inspection frame 2 and a robot frame 3 are sequentially arranged along the conveying direction of the product conveyor line 1. A vision inspection component 4 is installed on the vision inspection frame 2, and a four-axis parallel robot 5 is installed on the robot frame 3. The vision inspection component 4 and the four-axis parallel robot 5 are both located above the product conveyor line 1. A suction cup fixture 6 is installed at the bottom of the four-axis parallel robot 5. A control computer 7 is also provided on the robot frame 3. The product conveyor line 1, the vision inspection component 4, and the four-axis parallel robot 5 are all electrically connected to the control computer 7. In this invention, the product conveyor line 1 adopts a belt conveyor with adjustable speed to transport products along the direction of the four-axis parallel robot 5. The vision inspection component 4 can clearly capture images of the products on the product conveyor line 1. The four-axis parallel robot 5 is fixed above the product conveyor line 1 by the robot frame 3, featuring high speed and high precision. The control computer 7 can record sorting data, facilitating production management. By combining vision guidance and parallel robots, high-speed and high-precision automatic sorting and tray placement is achieved, improving the stability and efficiency of tray placement and reducing labor costs.

[0017] The visual inspection component 4 includes an industrial camera and a light source component. The industrial camera is electrically connected to the control computer 7 and is used to acquire product images and transmit them to the control computer 7 for identification and positioning.

[0022] Working principle: The product flows in from the input end of the belt conveyor. After the vision inspection component 4 detects the product, it determines the product's position and orientation. The four-axis parallel robot 5 picks up the product through the suction cup fixture 6 installed at the end and places the product into the tray 10 in the correct orientation. After the tray 10 is full, the worker removes the full tray 10, puts in a new empty tray 10, and continues the operation.
