Cartesian robots, also known as single-axis robots, industrial robot arms, electric cylinders, etc., are based on the XYZ rectangular coordinate system. The single-axis robot arm driven by servo motor and stepper motor is the basic working unit. The screw system, the timing belt and the rack and pinion are robot systems constructed by the common transmission mode, which can complete the arrival and follow the controllable motion track at any point in the XYZ three-dimensional coordinate system.
Cartesian robots can be easily used as various automation equipments due to different end-operating tools, such as welding, handling, loading and unloading, packaging, palletizing, demolition, inspection, flaw detection, sorting, assembly, labeling, Spraying, coding, (soft copy) spraying, target following, detonation and other work. Applications include electronics, machinery, automotive, food and many other industries.
Compared with the articulated robot, the Cartesian robot is not only simple in structure but also low in cost. The Cartesian coordinate combination method is flexible and can be assembled into single-axis to multi-axis robots, such as gantry, cantilever, wall-mounted, etc., and can also be customized for different loads, strokes, functions and special space requirements. Demand products. At the same time, the X, Y and Z axes can be extended to rotate the axis and flip the axis to form a five-degree-of-freedom and six-degree-of-freedom robot, or as a linear positioning system in professional automated machinery.
Compared to manual, Cartesian robots have unparalleled advantages. Right-angle coordinate robots have fast running speed and high repeatability, which can save labor costs and increase production capacity quickly. It is suitable for mass production, shortens delivery time, ensures product quality stability, uniformity and consistency, and manufactures. The products that come out are more secure.
According to the latest statistics, in 2014, the sales of most Cartesian robot manufacturers achieved a large increase. Last year, the sales volume of Cartesian robots in China reached 18,000 units, with a total output value of 162 million yuan, a year-on-year increase of 30%. At present, about 40% of the industrial robots used in China are Cartesian coordinates, and Cartesian coordinates are the most sold type of robots in the Chinese industrial robot market.
