Robots are the divine weapons of the beginning era of Industry 4.0. This is an outstanding work that combines multiple disciplines such as mechanics, electronics, motion, power, control, sensing and detection, and computing technology, and has not yet reached its ultimate conclusion. Their applications will cover all aspects of human life, learning, production... and in the industrial field, industrial robots correspond to them.
Replacing manual labor with industrial robots in production lines is currently a choice for many enterprises to reduce costs, increase efficiency, and improve production efficiency. However, due to the natural connection between industrial robots and high technology, the operation of industrial robots requires a certain level of knowledge reserve, which makes some production units hesitant. In fact, the operation of robots is not difficult, with advanced gameplay and ordinary people having their own process machines. Today, taking the Braun robot as an example, we will introduce the startup process of the robot and some basic knowledge of industrial robots.
1. Requirements and conditions for installing robots
During operation, the ambient temperature should be between 0 and 45 ° C (32 and 113 ° F); During transportation and maintenance, the temperature should be -10 to 60 ° C (14 to 140 ° F).
It must be used in an environment with an average altitude of 0-1000 meters.
The humidity must be below the dew point (relative humidity below 10%).
Places with less dust, oil fume, and water.
Flammable materials, corrosive liquids, and gases are not allowed in the work area.
Places with low vibration or impact energy for robots (vibration below 0.5G).
There should be no major electrical noise sources (such as gas-shielded welding (TIG) equipment), electromagnetic interference sources, electrostatic discharge, etc. nearby.
There is no potential danger of collision with mobile devices such as forklifts.
2. Installation of robots
Firstly, ensure the installation environment and space of the robot, as well as the installation location of the robot. It is necessary to first evaluate the layout of the factory where the robot is installed, the flatness of the ground, the power supply situation, etc., and then layout the position of the robot according to the motion range described in the instructions. To ensure that the robot has sufficient motion space, if there are corresponding backup operating ranges and parameters.
After confirming the installation position, use a forklift or other tools to transport the robot to the installation position for installation. The robot must be firmly fixed in the installation position during installation because the inertia of the robot itself is large during movement. If the installation position is not heavy enough or the installation is unstable, it is easy for the robot to tip over due to excessive force, causing unnecessary damage. It may even harm personal safety.
The design and layout of the safety fence are reasonable to prevent personnel from entering the robot's range of motion or colliding with the robot, which may cause personal injury accidents.
After placing the robot and control box, plug in the wiring cables and body of the electrical box control cabinet. Attention to inserting control cabinet cables: First, align the power and coding sockets, gently close the sockets inward and lock them, and do not use excessive force to damage the sockets. Connect the corresponding power supply according to the nameplate of the robot electrical box. Note that the equipment must be grounded and ensure good grounding. Finally, insert the teaching box into the control box.
3. Selection of installation method
Industrial robots can adopt various flexible installation methods based on their models and functional characteristics in different production environments and application requirements, to ensure that the robots can efficiently and safely complete their assigned tasks. These installation methods include but are not limited to ground installation, side slope installation, wall installation, and hanging inversion.
4. Body interface
After placing the robot and control box, plug in the wiring cables and body of the electrical box control cabinet. Connect the corresponding power supply according to the nameplate of the robot electrical box. Note that the equipment must be grounded and ensure good grounding. Finally, insert the teaching box into the control box.
5. Basic components of the controller
Controller, usually referring to the electrical box control cabinet, is the "external brain" of the robot, responsible for receiving and processing data from sensors, and commanding the robot's actions according to preset programs and algorithms. Controllers play a crucial role in robot systems, as they not only need to accurately interpret sensor signals, but also make quick decisions to ensure that robot actions are both precise and efficient. In addition, the controller also needs to communicate with other system components to ensure the coordinated operation of the entire robot.
The electronic control structure of a robot is a complex system, which includes key components such as servo system, control system, main control part, transformer, teaching system, and power communication cable.
The servo system is responsible for precise control of the robot's motion, ensuring that it operates according to the predetermined path and speed.
The control system is the core of the entire electronic control structure, integrating data from sensors and commanding the robot's actions according to preset programs and algorithms.
The main control section usually includes a central processing unit and related circuits, which are responsible for handling complex computing tasks and coordinating the work of various subsystems.
Transformers are responsible for providing stable power to the electronic control system, ensuring the normal operation of the system.
The demonstration system allows operators to manually guide robots to record action trajectories, thereby achieving complex operational tasks.
Finally, the power communication cable is the link that connects various components, ensuring smooth transmission of data and power.
6. Connection between controller and robot
External IO interface: connected to seven sets of input and seven sets of output signals of the robot, it is a 16 core reset connector
CAN, 485 interface: bus communication interface
Network port: used in TCP communication, supporting common communication methods such as MODBUS-TCP and Ethernet
Teaching pendant interface: the interface connecting the robot teaching pendant and the electrical control cabinet
Encoder line and power line interface: Connect servo motors on each axis of the robot to control motor drive
