Robot palletizing opportunities greatly reduce human capital and labor efficiency. The stacker is used to automatically stack the packaging bags, cartons or other packaging products sent by the belt conveyor according to the working mode of the customer's process standards, and then transport the stacked raw materials to the designated location through the electric forklift mechanical equipment.

Most of the operations performed by the cooperative palletizing robot are grasping and placing operations, that is, the robot grabs materials from the conveyor belt and places them on the designated position on the pallet along the motion path. Therefore, according to the position relationship between the robot and the conveyor belt and tray when it completes stacking, and considering the obstacles in the movement process, the "door" shaped movement track is selected. It should be noted that when the robot end effector completes the stacking of cartons at different positions on the pallet, the trajectory is in the shape of a "door", and the coordinates of the trajectory end point are different only because the positions of cartons on the pallet are different.

With the continuous implementation of industrial intelligence, logistics enterprises are also moving towards intelligence. There is no one to transport. Intelligent sorting has already been used in the transport industry. The birth of sorting robots has greatly improved various work efficiency, saved human costs, and will play an important role in the completion of intelligent logistics

The key technologies of cooperation include robot vision, sensors and control systems. The difficulty lies in how to realize the cooperation between robots and how to deal with the behavior of robots in complex environments.

With the mature application of artificial intelligence, big data, cloud computing and other technologies, robot manufacturing enterprises have enjoyed huge scientific and technological dividends. According to the statistical report of relevant data, the number of industrial machines put into use in the world has reached 3 million, with a year-on-year growth of 10%. It is estimated that by 2024, the number of new industrial robots in the world will reach about 500000/year. From the data, the demand for robots will increase year by year. On the one hand, robots improve work efficiency, on the other hand, the application of robots also reduces the pressure of manual management in enterprises.

Stacking robot is a kind of industrial robot, which is widely used at present. With the decline of labor rate and the rise of labor cost, palletizing robots are used more and more. Stackers and porters are manufactured in manufacturing enterprises to replace manual post packaging operations.

The advantages of the automatic production line are very obvious, but if the overall planning of the initial overall processing process layout is not good, the advantages of the automatic production line will be discounted. The automatic production line process layout is generally divided into linear layout, zigzag layout, and T-shaped layout

From the perspective of customers in the domestic market, due to the high flexibility and low cost of cooperative robots, SMEs are the main force in using cooperative robots. In addition, from a practical perspective, China's aging trend is becoming more and more obvious, and domestic labor costs continue to rise. The manufacturing industry is trying to find a more flexible and efficient production mode to alleviate the labor shortage and cope with the rapidly changing market
