Instar electrical teaches you how to choose your robot

Time:2017-12-02 10:00

   Under the background of machine substitutions, many enterprises have been interested in industrial robots. However, many enterprises can't choose their own industrial robots very well. Through this article, I hope you can have a general concept of the choice of industrial robots, and can have a choice.



   1.Application of robot

   The robot uses determines the type of robot, such as cutting, handling, welding and other work has a special robot, want sorting work quickly, you can choose to carry the Delta robot; in a small space, you can use the SCARA robot; if you want to complete the work in the process of obstacle avoidance, we need to use with multiple degrees of freedom the robot.



   2.The degree of freedom of the robot

   The degree of freedom of robots is also the number of axes of robots. The more the number of axes, the higher the degree of freedom of robots. The more flexible the robot is, the more complex the actions it can do. If only for simple pickup and placement work, then a four - axis robot is enough to do the work. But if a specific job is done in a relatively narrow space, the robot needs to be very flexible, so the six axis robot is a good choice. In theory, the more the number of axes, the stronger the flexibility, but the more the number of axes, the more complicated the programming work needs to be done, which depends on the specific work.




   The load of a robot determines the maximum weight that a robot can carry when it works. You need to have a recognition of the weight of accessories on your production line, and then choose the right weight.



   4.Maximum range of motion

   Every industrial robot has the largest range of motion and the farthest distance it can reach. At this time, it is necessary to consider whether its motion range is in line with its own needs.




   Generally speaking, the details will give the maximum speed to the inside and outside, and the efficiency of the robot with higher speed will be higher, and the time to finish the work in theory will be shorter.



   6.Repeatable positioning accuracy

   This parameter directly reflects the accuracy of the robot, the robot to repeat an action, reach a position there will be an error, the higher the accuracy of the robot error is small, the robot error generally within less than 0.5mm, if your application has a high requirement for the accuracy, then this data need to look at; if the application accuracy is not high, there is no need to repeat the very high positioning accuracy products.



   7.Inertia moment

   The details of inside and outside of the robot inertia torque and the axis of the allowable torque is very important for safe operation of the robot, if the application has certain requirements for the moment, need to carefully check the axis of the torque is not satisfied, if the overload may make robot fault.



   8.Protection grade

   If the robot using environmental dust or water will affect the operation of the robot, so please be sure to examine the protection level of the robot, the robot on a variety of different environments are different, on this condition, the robot selection and collocation of the working environment.
