Industrial robots are no longer a dream; more and more factories are adopting them to save on labor costs. This article will introduce industrial robots from two perspectives: 1. What is a casting robot among industrial robots? 2. What are the functional characteristics of industrial robots? If you are interested in this article, please continue reading.
one, What is a casting robot?
Among the many types of industrial robots, there is a type that can replace manual labor in casting, cleaning, machining, and other processes during the casting production process; this is called a casting industrial robot. Casting robots utilize state-of-the-art casting technology, thus maximizing production efficiency and minimizing production costs.
In manufacturing workshops, workers often face harsh working conditions, frequently filled with high temperatures, dust, and noise. This makes the emergence of industrial robots in the casting industry particularly important. Manufacturing robots not only replace human workers in dangerous environments but also maintain flexible, continuous, and high-speed production processes. Our casting equipment is now organically integrated with industrial robots, covering major areas such as die casting, gravity casting, and low-pressure casting.
Traditionally, the foundry industry relies on manual labor for production. However, with the automation of industrial production processes, the application of industrial robots will become increasingly widespread. As the demands for casting quality rise, foundry industrial robots will receive increasing attention from businesses.
II. Functional Characteristics of Industrial Robots
The functional characteristics of industrial robots affect their working efficiency and reliability. The following functional objectives should be considered when designing and selecting robots:
( 1 ) Degrees of Freedom Degrees of freedom are the primary indicator for measuring the skill level of a robot. A degree of freedom refers to the independent motion of a moving part relative to a fixed coordinate system. Each degree of freedom requires a servo axis for drive; therefore, the higher the degree of freedom, the more complex the actions the robot can perform, the stronger its versatility, and the wider its application range, but correspondingly, the greater the technical difficulty. Generally, general-purpose industrial robots have 3-6 degrees of freedom.
( 2 ) The workspace refers to the spatial scale in which the robot uses its gripper to perform tasks. The wrist reference point for describing the workspace can be selected at the center of the hand, the center of the wrist, or the fingertips. The size and shape of the workspace will vary depending on the reference point. The robot's workspace depends on the robot's construction method and the range of motion of each joint. The workspace is a primary functional objective of industrial robots and a key objective in designing industrial robot layouts.
( 3 ) Load-bearing capacity Load-bearing capacity refers to the maximum weight that a robot can bear in any position within its working range. The magnitude of the load-bearing capacity depends on the mass of the load, the speed of operation, and the magnitude and direction of acceleration. Based on different load-bearing capacities, industrial robots are roughly divided into: ① Micro robots - load-bearing capacity below 10N ; ② Small robots - load-bearing capacity of 10-50N; ③ Medium robots - load-bearing capacity of 50-300N; ④ Large robots - load-bearing capacity of 300-500N ; ⑤ Heavy robots - load-bearing capacity above 500N .
( 4 ) Motion speed. Motion speed affects the robot's working efficiency and motion cycle, and it is closely related to the gravity and positioning accuracy obtained by the robot. The higher the motion speed, the greater the dynamic load on the robot, and the greater the inertial force during acceleration and deceleration, which affects the robot's working stability and positioning accuracy. At present, the maximum linear motion speed of general robots is mostly below 1000 mm/s , and the maximum reverse speed usually does not exceed 120 ° /s .
( 5 ) Positioning accuracy is another technical indicator for measuring the quality of robot operation. The positioning accuracy of industrial robots includes positioning accuracy and repeatability. Positioning accuracy depends on the positioning control method and the accuracy and rigidity of the robot's moving parts. In addition, it is closely related to factors such as gravity and motion speed. Repeatability is the accuracy of the robot in repeatedly positioning a certain position. The typical positioning accuracy of industrial robots is usually in the range of ±0.02mm to ± 5mm .
