Automatic Equipment
The DEMO is the automation equipment after adaption and modification.
A. The pros and cons of using industrial robots
B. Choose the type of robot according to your needs
In order to play the value of robots in industrial production, it is necessary to understand different types of robots and use them in suitable production processes. The following will briefly introduce various types of robots.
Single axis robot
Single-axis robots usually use linear guides as linear guides or with deceleration mechanisms for rotating applications, and then use servo motors/stepping motors to achieve positioning. It is usually used for plane transfer, transportation, or use with other robots as external axes.
Cartesian robot
Cartesian coordinate robot is a robot that combines linear single-axis robots into X, Y, and Z coordinate directions. The advantages of Cartesian coordinate robots are high-precision positioning, and because the mechanism can withstand heavier loads, it is also commonly used in molding machine pick-and-place, packaging operations, coordinate measurement, and high-load handling and stacking.
SCARA robot
The horizontal articulated robot has only 4 degrees of freedom, the movement range is cylindrical coordinates, and the vertical pick-and-place or plug-in process is carried out through the up and down movement of the Z axis. Another feature of it is fast moving speed, high repeat accuracy, but small load.
Most of them are used for fast sorting and precision assembly. It is often used in the handling of panels, wafers or circuit boards, and the insertion of electronic components.
Parallel robot (DELTA robot)
DELTA robot is also called spider-hand robot. The structure of this robot is relatively simple, and the structure can achieve fast and high-precision movement. Therefore, it is often used in high-speed selection operations, and is commonly used in rapid inspection and selection of food electronics and pharmaceuticals.
Articulated robot
The multi-joint robot is designed to imitate the human arm. It is composed of many joints and has a relatively high degree of freedom. It can almost reach any trajectory or position in the spherical coordinates. Therefore, many complex processes such as assembly, handling, packaging, welding, and grinding can be performed. It is also the most common industrial robot currently used for complex tasks in the automotive industry, metal manufacturing industry and electronics-related industries.
Finally, I will help you to make a simple comparison table to help you choose.
C. Notes for robot selection
The following robot parameters must be paid attention to in the robot selection catalog to meet the requirements of the production line.
Degree of freedom
The degree of freedom can be understood as the number of moving axes of the robot, although not all the same. The higher the degree of freedom, the higher the flexibility, but the complexity of programming will increase.
Maximum load (load capacity)
The maximum load that the robot can bear within the working range of the robot. The robot load depends not only on the weight, but also the torque generated by the magnitude and direction of the running speed and acceleration.
Working range
The working area of the robot is the area formed by all the position points that the end of the robot arm can reach.
Moving speed
The fastest moving speed at the end of the robotic arm. Speed will affect production efficiency, so the robot’s moving speed and acceleration and deceleration capabilities are also very important. Because it must be ensured that the robot can still have considerable stability when working at high speed.
Repeatability
Repeat positioning accuracy refers to the accuracy with which the robot arm returns to the same target position. During the production process, the robot will repeatedly move to the same position. At this time, there will be a slight error. The higher the accuracy, the smaller the position error.
Waterproof and dustproof grade
When there are dust or moisture conditions in the production environment of the factory, you need to consider the waterproof and dustproof level of the robot. Otherwise, it will cause malfunctions or shorten the service life of the robot.
D. Comparison of different brands
Yaskawa Electric Co.-Japan
Since Yaskawa Electric developed the first all-electric industrial robot in 1977, it has 28 years of robot R&D and production history. It has subsidiaries such as Motoman America, Sweden, Germany, and Synetics Solutions America. Its core industrial robot products include: spot welding and arc welding robots, painting and processing robots, LCD glass plate transfer robots and semiconductor wafer transfer robots.
