In the sci-fi movie "Iron Man", Tony has a robotic arm "Stupid". It can not only talk to the protagonist, but also help the master make Iron Man's uniform. This robot that seems to exist only in sci-fi movies has already Become reality. That is the collaborative robot that is very popular in the field of robotics.
Compared with the gigantic traditional industrial robots we see every day, collaborative robots are a step forward in human-machine interaction. They can work together with people on the production line, and give full play to the efficiency of robots and the ability of human beings themselves. Collaborative robots are not only cost-effective, but also safe and convenient, which can greatly promote the development of manufacturing enterprises.
Of course, some people will ask: Will robots and humans work together without accidentally injuring humans? Don't worry about this, at the beginning of the birth of collaborative robots, the International Organization for Standardization ISO/TC 184/SC2 WG3 was commissioned and compiled the ISO/TS15066 technical specification "Robots and Robotic Equipment - Collaborative Industrial Robots". Therefore, to become a collaborative robot, it needs to meet the safety requirements of ISO/TS 15066. Its specific requirements are mainly divided into the following four points:
①Safety-level monitoring stops. When someone enters the test area, the robot must stop working; ② Manual guidance. The collaborative robot can only work according to the operator's touch force; ③ speed and separation monitoring. The robot can work only when there is a certain distance between it and the human; ④ The power and power are limited by the controller and the built-in design. When a touch accident occurs, the robot must reduce the output power to prevent the accident.
From the above production requirements, we can find that the safety of collaborative robots is fundamentally guaranteed. To ensure the safety of users, it is not only necessary to comply with basic safety requirements, but also requires manufacturers to continuously innovate and improve the safety performance of the machine. Taking the Shanghan's collaborative robot, which is second to none in the industry, as an example, it fully guarantees the safety of users: when someone or something approaches, it will automatically rebound and then stop. In the event of a sudden power failure or emergency stop, it will be locked immediately, there will be no sliding, downward trend, and it will not be able to move an inch. Therefore, it can replace workers to do complicated, dangerous and polluting work, such as welding, cutting, handling, pipeline inspection, machine tool management, etc.
Looking forward to the future, collaborative robots, as a good helper for safe and secure production lines, will provide manufacturing enterprises with unlimited possibilities for speeding up automation transformation and upgrading and enhancing their competitiveness, which is worth looking forward to.
