From eight perspectives, I'll teach you how to choose the right industrial robot

in the era of "machine replacement", many enterprises from the government level have a strong interest in industrial robots, but many enterprises can't choose the right industrial robot for themselves. Through this article, I hope you can have a general concept of the choice of industrial robots, and have a choice direction

first of all, it is necessary to understand what to do with industrial robots, that is, the purpose. There are very professional robots in every industry, such as welding robots, cutting robots, spraying robots, stamping robots, and so on. There are corresponding professional robots that can be used. To determine the scope of application, it is necessary to determine the model you need according to the parameters of the robot

1. Application purpose of robot

the purpose of robot determines the type of robot, 6 Compromise: there are special robots for material stretching, such as cutting, handling, welding and so on. If you want to sort quickly, you can choose delta robot; SCARA robot can be used to carry out transportation in a narrow space; If you want to complete obstacle avoidance in the working process, you need to use a robot with multiple degrees of freedom

2. Robot degree of freedom

robot degree of freedom is the number of axes of the robot. The more the number of axes, the higher the degree of freedom of the robot, the stronger the flexibility of the robot, and the actions it can do can be more complex than thermoplastic elastomers such as polystyrene. If it is only used for simple picking and placement, a four axis robot is enough to complete the work. However, if a specific work is completed in a relatively narrow space, the robot needs to have strong flexibility, so the six axis robot is a good choice. Theoretically, the more the number of axes, the stronger the flexibility. However, the more the number of axes, the more complex the programming work needs to be done, which depends on the specific work

3. Robot load

the number of international enterprises attracted by robots this exhibition has increased compared with previous years. The load determines the maximum weight that robots can carry when working. You need to have an understanding of the weight of accessories on your production line, and then choose the appropriate weight

4. Maximum range of motion

every industrial robot has the maximum range of motion and can reach the farthest distance. At this time, we need to consider whether its range of motion meets our own needs

5. Speed

generally speaking, the maximum speed will be given in the detail table. Robots with high speed will be more efficient, and the time to complete the work will be shorter in theory

6. The parameter of repeated positioning accuracy

directly reflects the accuracy of the robot. When the robot repeats an action and reaches a position, there will be an error. The higher the accuracy, the smaller the error. Generally, the error of the robot is within ± 0.5mm. If your application requires very high accuracy, then this data needs to be looked at emphatically; If the accuracy requirements of the application are not high, it is not necessary to choose products with very high repeated positioning accuracy

7. Inertia torque

the inertia torque in the robot detail table and the allowable torque of each axis have a very important impact on the safe operation of the robot. If the application has certain requirements for torque, it is necessary to carefully check whether the torque of each axis is met. If overloaded, the robot may fail

8. Protection level

if the environment used by the robot has dust or water, which will affect the operation of the robot, please be sure to study the protection level of the robot. Different robots have different adaptability to various environments. Look at this condition and choose the robot matching the working environment
