In modern manufacturing, industrial robots are used more and more widely as a key tool to improve production efficiency and product quality. However, with the increase in human-machine collaboration scenarios, ensuring the safety of operators has become one of the core considerations in the design and application of industrial robots. To achieve this goal, manufacturers and technology developers have adopted a series of advanced technologies and measures to improve safety, thereby minimizing potential risks while ensuring efficient production.First of all, at the hardware level, the design of industrial robots pays more and more attention to intrinsic safety. This means that from the mechanical structure to the drive system, every link is carefully designed to reduce the possibility of harm to humans. For example, the shell with rounded corners and soft materials can effectively prevent scratches or impact injuries to operators during collisions. At the same time, by optimizing the joint design and dynamic parameters, the robot is smoother and smoother during operation, reducing unexpected impacts caused by sudden acceleration or deceleration. In addition, some new robots are equipped with torque sensors and compliant control algorithms, which can detect and adjust the force output immediately when they come into contact with obstacles (including human bodies) to avoid excessive squeezing or pushing and pulling.Secondly, speed monitoring is one of the important means to ensure safety. According to different working modes and task requirements, industrial robots can automatically adjust the movement speed. When entering the human-machine coexistence area or performing low-risk tasks, the robot will automatically reduce the speed or even suspend the operation to ensure that even if contact occurs, it will not pose a serious threat to personnel. At the same time, with the help of advanced visual systems and environmental perception technology, the robot can monitor the state of the surrounding space in real time. Once it finds someone approaching the dangerous area, it will respond quickly, such as slowing down, changing the path or stopping the action, and will not continue to perform the task until it is confirmed to be safe.Furthermore, the emergency stop function is also an indispensable safety measure. Whether it is the built-in manual emergency stop button or the software trigger mechanism in the distributed control system, it allows the operator to immediately interrupt all activities of the robot when it detects potential danger. It is worth noting that this emergency stop is not a simple and rough power cut, but an orderly shutdown process completed through the preset safety logic, which not only ensures that the equipment itself is not damaged, but also protects the safety of personnel to the greatest extent.In addition to the above safety measures that directly act on the physical level, a sound operating procedure and training system are also crucial. Enterprises need to provide employees with adequate safety education so that they understand how to use robots correctly and what response strategies to adopt in emergency situations. This includes but is not limited to wearing appropriate personal protective equipment, following standardized operating procedures, and regularly participating in emergency drills. Only when every participant has a high level of safety awareness and is proficient in relevant skills can a comprehensive safety barrier be truly built.In addition, with the development of artificial intelligence and Internet of Things technologies, intelligent monitoring systems have also begun to be applied to the safety management of industrial robots. These systems can collect data from various sensors, analyze the operating status of the robot and the changing trends of the surrounding environment, predict possible failures or dangerous situations, and issue early warning signals. In this way, not only can hidden dangers be eliminated in a timely manner, but the safety management level of the entire production line can also be further improved.In summary, around the human-machine collaboration safety issues of industrial robots, a comprehensive solution covering multiple dimensions such as hardware design, software control, personnel training, and intelligent management has been formed. Through the effective implementation of these measures, not only the reliability of industrial robots working in complex and changing environments has been greatly improved, but also a solid guarantee has been provided for creating a safer and more harmonious working environment. In the future, with the continuous advancement of technology and the continuous improvement of society's requirements for safe production, it is believed that more innovative safety technologies will be introduced into the field of industrial robots, pushing the industry to a higher level.
