Articulated robots, also known as articulated arm robots or articulated robotic arms, are one of the most common forms of industrial robots in today's industrial field, and are suitable for mechanical automation operations in many industrial fields. For example, automatic assembly, painting, handling, welding and other work are classified according to the structure.
The main classification of articulated robots
Classification according to the structure of articulated robots:
1. Five-axis and six-axis articulated robots: with five or six rotational axes, similar to human arms; The application areas include loading, unloading, painting, surface treatment, testing, measurement, arc welding, spot welding, packaging, assembly, chip machine tools, fixing, special assembly operations, forging, casting, etc.
2. Pallet joint robot: two or four rotating axes, and a positioning and locking device of a mechanical gripper; Applications include loading, unloading, packaging, special handling operations, pallet transportation, etc.
3. Planar articulated robot SCARA: three parallel axes of rotation and one linear axis; The application fields include loading, unloading, welding, packaging, fixing, coating, painting, bonding, packaging, special handling operations, assembly, etc.
In addition, it can also be classified according to the nature of the work of the joint robot, which can be divided into many kinds, such as: handling robots, spot welding robots, arc welding robots, painting robots, laser cutting robots and so on.
Advantages of articulated robots:
1. It has a high degree of freedom, 5-6 axes, and is suitable for almost any trajectory or angle of work.
2. It can be freely programmed to complete fully automated work.
3. Improve production efficiency and controllable error rate.
4. Replace many complex tasks that are not suitable for human completion and harmful to health, such as spot welding of automobile shells.
Disadvantages of articulated robots:
1. The price is high, resulting in a high cost of initial investment.
2. A lot of preparation work before production, for example, the programming and computer simulation process takes a long time.
