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

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.

Many people have only a general understanding of stackers. They believe that the stacker is a simple mechanical equipment used for handling and stacking goods. In fact, the stacker is not just a simple mechanical equipment. Many production workshops have palletizing robots to load, unload and stack goods. The use of palletizing robots is several times more efficient than traditional labor, but it can also reduce the human cost of enterprises.

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.

In many industries, collaborative palletizing robots have been used to replace manpower and simplify work. It is generally used for lightweight practical product packaging. Collaborative intelligent robots put objects or services into small boxes or trays. The intelligent robot of automobile palletizing cooperation can accurately stack small boxes, aquariums, packaging bags, pallets, and packaging cartons in the medium and heavy load areas in the pallet.

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.

The stacking work is completed in the form of a mechanical arm. Stacking is one of the most promising cooperative robot applications, but before introducing in detail, let's start with a simple definition. Palletizing or palletizing refers to the act of placing products on pallets for shipment or storage in the logistics supply chain. Ideally, products should be stacked in a way that maximizes the weight and volume of products under load, and they should be stable enough to prevent products from moving, dumping or squeezing each other.

The disadvantages of manual palletizing of cooperative palletizing robot are pointed out: the palletizing form is irregular, the palletizing is often reversed, and there are potential safety hazards. In the loading process, due to the irregular stacking form, the loading capacity is low and the transportation cost is high. Low stacking efficiency and high labor cost.
