Compared to articulated robots, Cartesian robots not only have a simple structure, but also have low cost. They can be flexibly assembled into single axis to multi axis robotic arms, or serve as linear positioning systems in professional automation machinery. Currently, they have been widely used in industries such as electronics, machinery, automotive, rubber, chemical, food, energy, etc., and have played an important application value in industrial automation production. According to the size of the load, Cartesian coordinate robots can be divided into two categories: heavy load robots are represented by European and American brands, with a load capacity of more than 50kg, a large travel distance, and fast operating speed. They have advantages in moving loads in industries such as machinery and automotive manufacturing; The light load category is represented by Japanese and Taiwanese brands, with loads mostly within 20kg during use. It has high repeatability and positioning accuracy, making it very suitable for the electronic manufacturing industry with high precision requirements. On the basis of representing various brands of industrial robots and downstream application enterprises, Weiya Automation has selected the top five brands of light load and heavy load Cartesian coordinate robots in the domestic market from the aspects of product technical strength and market service.
