Cooperative robot is an important branch of industrial robot. The cooperative robot is mainly lightweight, and its structure is relatively simple, so the whole robot lacks rigidity. Therefore, the load of cooperative robot is generally lower than that of traditional industrial robot, and its working range is only similar to that of human arm. The application of cooperative robot products meets the requirements of precision assembly, inspection and man-machine joint operation.

The role of robots in industry has replaced human workers in many manufacturing industries. Machines like mechanical arms make it possible for humans to perform tasks with brute force before automation. Now they have replaced heavy lifting and precision assembly. The use of industrial robots can not only help create products, but also reduce waste and improve safety.

Cooperative palletizing robot, an industrial robot, is a key emerging industry in China's implementation of the manufacturing power strategy. The development level of robot industry is an important symbol to measure a country's innovation ability and industrial development level.

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.

The use of automated production lines for mass production in enterprises can improve labor productivity, stabilize and improve product quality, improve working conditions, reduce production floor space, reduce production costs, shorten production cycle, and ensure production balance, which has significant economic benefits.

Our innovation and technology are developing more and more rapidly, so if we want to slow down the labor force of modern people and improve work efficiency, we will certainly use industrial robots to help us. The most common cases of robot industrial applications should be transportation and stacking. The difference between palletizing robot and handling robot is determined by his work content. In comparison, the palletizing robot is easier to control.

The food manufacturers attending the meeting paid special attention to cooperation and robots to minimize the dependence on human capital and achieve more convenient food solutions. A packaging engineer in charge of large and medium-sized food companies said in the report that about one fifth of the company's plants in North America use cooperative robots, "mainly for loading and stacking. We are ready to invest again in areas that can replace labor.

With the accelerated development of industry, intelligent devices represented by industrial robots are facing unprecedented development opportunities. For many years, China has been the main consumer market of intelligent robots.
