In the era of "machine substitution", many companies have a strong interest in industrial robots, but many companies are not good enough to choose their own industrial robots. Through this article, I hope that everyone can have a general concept of the choice of industrial robots, and can have a choice direction.
The first is to understand what to do with industrial robots, that is, the use, each industry has very professional robots, such as welding robots, cutting robots, painting robots, stamping robots, etc. have corresponding professional robots can be used. To determine the scope of application, it is necessary to determine the model you need based on the parameters of the robot.
1. Application of the robotThe use of the robot determines the type of robot to be selected. There are special robots for cutting, handling, welding, etc. You can select the Delta robot if you want to sort quickly. If you want to carry it in a small space, you can use the scara robot. If you want to complete obstacle avoidance during the work process, you need to use a robot with multiple degrees of freedom.
The degree of freedom of the robot is also 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 more action that can be done. If it's just for simple pick and place work, then a four-axis robot is enough to do the job. But if you need to do a certain job in a relatively narrow space, then the robot needs to have a lot of flexibility, then a 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. This depends on the specific work.
3. Robot loadThe load of the robot determines the maximum weight that the robot can carry while working. You need to know the weight of the accessories on your production line, and then choose the right weight.
4. Maximum range of motionEvery industrial robot has the largest range of motion and the longest distance that can be reached. It is necessary to consider whether its range of motion meets its own needs.
5. SpeedIn general, the maximum speed will be given in the details table. The speed of the robot will be higher and the time to complete the work will be shorter.
6. Repeat positioning accuracyThis parameter directly reflects the accuracy of the robot. The robot repeats an action. There is an error when it reaches a position. The higher the accuracy, the smaller the error of the robot. The general robot error is within ±0.5mm. If your application is accurate. The requirements are very high, so this data needs to be taken seriously; if the accuracy of the application is not high, there is no need to choose a product with very high repeatability.
7. Moment of inertiaThe moment of inertia in the robot details table and the allowable torque of each axis have a very important influence on the safe operation of the robot. If the application has certain requirements on the torque, it is necessary to carefully check whether the torque of each axis is satisfied. If the overload may make the robot A failure has occurred.
8. Protection levelIf the environment used by the robot is dusty or has water that will affect the operation of the robot, then it is important to study the degree of protection of the robot. Different robots have different adaptability to various environments. Look at this condition, select and work. The environment is matched with the robot.
