Robotic machine protection: avoid these 7 fatal risks

2021-05-10 17:38:06

Unlike traditional machines, industrial robots lack the intelligence of human operators. If a programming error or hardware failure occurs, the robot may accidentally move a long distance at a high speed, causing serious danger to the operator or maintenance personnel.
  Like any machine, if the robot is improperly deployed or used improperly, it can be dangerous.
  This makes it more difficult to choose a suitable protection method than traditional automation. In traditional automation, the operating range, movement and other performance parameters are defined.
  The following are seven potential risks of robotics:
  Human error: Pre-programming, connecting activated peripherals, or connecting real-time input and output sensors to microprocessors or peripherals are listed as human errors. These errors may cause dangerous and unpredictable movements or actions of the robot. The operator may put himself in a dangerous position due to being too familiar with or not understanding the movement path of the robot.
  Control error: If the control system fails and is closely related to human interaction, the system response may lead to a dangerous working environment.
  Unauthorized access: Unauthorized operators can find themselves in dangerous and potentially fatal areas that are unfamiliar with safety hardware.
  Mechanical failure: In the design and programming stage, mechanical part failure is not always considered. Failures can lead to potentially dangerous situations.
  Environmental source: If there is no plan to suppress surge or power loss in the initial stage of the project, it may cause injury.
  Power system: In the robot power system, the pneumatic, hydraulic or power supply of the control or transmission element failure will interfere with the electrical signal of the control and/or power line. This creates a dangerous release of energy.
  Improper installation: If the robot work cell is set up incorrectly, it may cause danger due to the difference in the original design.

General robot specifications
  Robot size (kg): The physical size and weight of the industrial manipulator need to be considered to ensure that the manipulator matches the existing systems and equipment in the workshop.
  Larger payload capacity (kg): The industrial applications and specifications of robots are usually closely integrated. Not only need to consider the size and weight of the part, but also need to add the weight of the end-of-arm tool to the formula.
  Repeatability (mm): Repeatability refers to the ability of the robotic arm to return to the previous point. The repeatability of many industrial robot arms currently ranges from +/- 0.5 mm to +/- 0.02 mm. Factors such as the number of axes, size, and range affect repeatability.
  Vertical and horizontal extension (mm): The extension capacity of an industrial robot arm usually plays an important role in determining whether the arm is suitable for the application. The robotic arm needs to be able to reach all the necessary areas of the part it is processing or the system it is working on.
  When choosing an industrial robot arm, you also need to consider other industrial robot specifications. For example, axis speed and range of motion affect cycle time and working range. For more information on choosing the right robotic arm for industrial applications, please call us now.
