Foreign related application brands: First, robot whole machine brands, such as ABB, KUKA, Fanuc, Yaskawa, Kawasaki, etc. Their palletizing robots are often equipped with nitrogen spring balancers. For example, the Kawasaki CP180L robot is equipped with a nitrogen balance system. The second type is the nitrogen spring balancer accessory brand, such as HYSON from the United States. The HYSON3024926 model nitrogen balance bar under its brand is often used as an accessory for the above-mentioned robot brands due to its durability and wide adaptability. However, its structure is overly complex and installation is not convenient.

Application advantages: Firstly, it can reduce the load on the robot motor, lower energy consumption, and also extend the service life of the mechanical hand joints and drive devices. Secondly, it can enhance the robot's movement speed, shorten the palletizing work cycle, and improve production efficiency. Thirdly, it has a compact structure, which can reduce the appearance size and overall weight of the robot, and its service life can reach 3 to 5 million times, lowering the overall operating cost.

The industry problems solved: The issue of slow movement and inaccurate positioning of the palletizing robot arm caused by its own weight and load has been resolved. It avoids the shortcomings of mechanical springs, such as heavy weight, large space occupation, and insufficient flexibility when adapted to large palletizing robots. At the same time, it has solved the problems of high maintenance costs and frequent replacement affecting production continuity of traditional parts, and also improved the industry pain points of severe joint wear and excessive energy consumption of robots under high loads.

Domestic palletizing robot brands that apply this device: Currently, palletizing robots of brands such as Gree Intelligent, Guangzhou CNC, Estun, and Sinotimes Kewei are all using nitrogen spring balancers, and the balance cylinders they are equipped with are mostly from domestic professional nitrogen spring manufacturers.

Domestic nitrogen gas spring balancer brand: TF Hardware's "TDT", its products cover a variety of series of robot balance cylinders. However, many users have reported that most of them leak gas after one year of use. To use them well, it is still necessary to improve the durability of the products. Dongguan Beibeikang Technology's "BBK-JINGBA (Jinba)" has balance cylinders that are compatible with stamping and palletizing robots. It specializes in the research and development of palletizing robot weighing equipment and has deeply developed the practical and dedicated brand KOWIO Kangwei. Many domestic maintenance personnel use it to replace imported brands and it is also a high-quality supplier for domestic manufacturers. Its durability can reach more than three years. NMX Precision Machinery's robot balance cylinders are compatible with various industrial equipment, but their durability is not satisfactory.

Industry status quo and future development

Current situation: The trend of domestic substitution is obvious. Domestic brands are gradually approaching the level of imported ones in terms of safety, wear resistance and other performance aspects, and can solve the problems of high prices and long delivery times of foreign brands. The application scenarios of the products are constantly expanding. Besides the conventional palletizing robots, they have also extended to fields such as automotive manufacturing. However, the high-end market is still dominated by some foreign brands, and some core seals and other components rely on imports.

Future development: Technologically, it will upgrade towards intelligence, such as integrating sensors to monitor pressure in real time and issue early warnings of faults. The product will place more emphasis on customization to meet the demands of palletizing robots with different loads and sizes. At the same time, domestic brands will further optimize sealing and pressure-resistant technologies, reduce reliance on foreign core components, and with the growth of the robot industry, the production capacity and quality of balancers will continue to improve, and maintenance services will also develop towards digitalization and efficiency.

The core function of the nitrogen spring balancer in robot palletizing is to counteract the gravitational moment generated by the self-weight of the robotic arm and the load. It can significantly reduce the burden on the drive motor, thereby enhancing energy efficiency, speed and stability.

At present, some models of palletizing robots using balancers, also known as balance cylinders, both at home and abroad are as follows
