What Are The Types Of Industrial Robots And How To Choose

As the application of industrial robots in the industrial field becomes more and more common, you will find that the demand for various types of industrial robots is also increasing to adapt to specific occasions. In order to let everyone better understand industrial robots, this article will be the type of industrial robots to carry out the introduction of relevant content.
The word "robot" captures the imagination of many people, and when they hear the word, they think of humanoids or cyborgs. However, industrial robots are not humanoid robots, they are robots developed to automate intensive production tasks, which can be fixed in one area or moved to complete the task, although they can copy human movements, but with the strength, precision and speed of a machine.
Industrial robot is a kind of mechanical equipment that can automatically perform tasks. It can be classified according to different standards such as structural form, control mode, motion mode and application field. If it is classified according to structural form, it can be divided into multi-joint robot, cartesian robot, SCARA robot and parallel robot. Here is a brief introduction to these four types of industrial robots.
1. Multi-joint robot
It is one of the more interesting types of industrial robots. Its accuracy and action style is similar to the human arm, the arm is connected to the base through the torsion joint, the arm has a rotating joint, the number of joints can be from simple two joints to seven joints, etc., each joint provides a degree of freedom, can be parallel to each other or vertical, allowing free movement, thus providing greater flexibility in the working environment.
It can be used in welding, handling, painting and assembly in many other situations, such as welding, welding is one of the first applications of multi-joint robots, in this case, a main reason for its excellent performance is its flexibility. Because when welding, it is usually necessary to move accurately at a specific Angle, which is impossible for Delta robots or other industrial robots to complete, so multi-joint robots can be used to complete these difficult welding tasks.
2. Cartesian robot
It is a more common industrial robot in the industry, can also be called the gantry robot, with three linear joints, such as the x axis, Y axis and Z axis, it has an attached wrist, the wrist can be rotated, and the three joints are no way to rotate, but can provide linear motion along the axis, using a linear slide to carry out three translations.
Because the cartesian robot can replace different end tools, it can be applied to loading and unloading, palletizing, testing and other occasions, such as loading and unloading, it can usually be applied to the machine tool or production line loading and unloading occasions, can complete the material loading, unloading and flipping, etc., in place of manual loading and unloading tasks, to avoid direct contact between the human body and the machine tool. Making the whole production process safer.
3. SCARA robot
It is a relatively small industrial robot, usually installed on the base or the floor, some can also be installed on the wall to complete the task. It usually has four joints, or four axes, and can move along the x, Y, and Z axes in a plane, and can rotate 360 degrees around the Z axis.
It is usually used in the automotive industry, electronics industry and plastics industry, mainly used in assembly and transportation and other occasions, such as assembly, in the electronics industry, it can complete efficient dispensing, label pasting, locking screws and screw removal and other assembly-related tasks, with high positioning accuracy and movement speed.
4. Parallel robots
The Delta robot, for example, is a high-speed, light-load parallel robot that typically has three follower arms attached to a single base above the work surface. Since it utilizes multiple computer-controlled arms to support an end tool, the position of the end tool can be easily controlled by its arms, allowing for high-speed operation.
It has been widely used in the industrial field with high precision and high speed, especially in the food industry, pharmaceutical industry and electronics industry, etc., mainly used in sorting, welding and assembly occasions, such as sorting, Delta robot can generate the corresponding sorting procedure according to the size of the product, placement mode and pallet size and other conditions, in the production process, Only need to select the corresponding program or receive the instructions of the host computer, you can complete the sorting of different products.
