What are the parameters of industrial robot training equipment?

Types of Industrial Robots The first thing you need to know is where you are going to use your robot. This is paramount when choosing the type of robot you need to buy. If you just want a compact pick and place robot, the Scara robot is a good choice. If you want to place small items quickly, the Delta robot is the best choice. If you want the robot to work together next to workers, you should choose a collaborative robot. Here are some specific metrics. Robot Load Load is the maximum amount of weight the robot can carry while working. If you need to move a part from one machine to another, you need to account for the weight of the part and the weight of the robot's gripper within the load. Degrees of Freedom (Number of Axes) The number of robot axes determines its degrees of freedom. For simple applications, such as picking and placing parts between conveyor belts, a 4-axis robot is sufficient. If the robot needs to work in a confined space and the arm needs to twist and reverse, a 6- or 7-axis robot is the best choice. The choice of the number of axes usually depends on the specific application. It is important to note that a higher number of axes is not just for flexibility. In fact, if you want to use the robot for other applications as well, you may need more axes than you can use. But there is a downside to having more axes, if you only need 4 of the 6 axes in a 6-axis robot, you still have to program the remaining 2 axes. Robot manufacturers tend to name axes or joints with slightly different names. Generally, the joint closest to the base of the robot is J1, followed by J2, J3, J4 and so on up to the wrist. Other manufacturers like Yaskawa Motoman use letters to name the axes. Maximum Range of Motion When choosing a robot, you need to know the maximum distance the robot will reach. Choosing a robot should not only focus on the load but also on its maximum range of motion. Each company will give you the range of motion of the robot, and you can see from that if it fits the needs of your application. The maximum vertical range of motion is the range between the lowest point the robot's wrist can reach (usually below the robot's base) and the highest point. The maximum horizontal range of motion is the distance between the furthest point the robot wrist can reach horizontally and the centerline of the robot's base. You will also need to refer to the maximum range of motion (expressed in degrees). These specifications vary greatly from robot to robot and have limitations for some specific applications. Repeat Accuracy The choice of this parameter also depends on the application. Repeat accuracy is the degree of precision/discrepancy with which the robot reaches the same position after completing each cycle. Typically, robots can achieve accuracy within 0.5mm or even higher. For example, if the robot is used to manufacture circuit boards, you will need a robot with ultra-high repeat accuracy. If the application being worked on does not require a high degree of accuracy, then the robot's repeatability can be less high. Accuracy is usually expressed as "±" in the 2D view. In reality, since the robot is not linear, it can be positioned anywhere within the tolerance radius. Speed Speed varies for different user needs. It depends on how long the job takes to complete. The specification sheet usually only gives the maximum speed, and the robot can provide a speed between 0 and the maximum speed. It is usually given in degrees per second. Some robot manufacturers also give the maximum acceleration. Robot weight Robot weight is also an important parameter for designing a robot cell. If the industrial robot needs to be mounted on a customized table or even a track, you need to know its weight and design the support accordingly. Braking and Moment of Inertia Robot manufacturers generally give information about the braking system. Some robots give braking information for all axes. In order to determine a precise and repeatable position in the workspace, you need a sufficient number of brakes. The moment of inertia for specific parts of the robot can be requested from the manufacturer. This is crucial for the safety of the robot. You should also pay attention to the allowable moments for each axis. When your application requires a certain amount of torque to accomplish, for example, you need to check if the allowable torque for that axis can be met. If it can't, the robot is likely to fail due to overloading. Protection level This also depends on the level of protection required for the application of the robot. Robots working with food-related products, laboratory instruments, medical instruments or in flammable environments require different levels of protection. This is an international standard and needs to be differentiated by the level of protection required for the actual application or selected according to local specifications. Some manufacturers offer different levels of protection for the same model of robot depending on the environment in which the robot will be working.
