Collaborative robots are an important branch of industrial robots. Collaborative robots are mainly lightweight design, relatively simple in structure, and insufficient rigidity of the entire robot. Therefore, the load of collaborative robots is generally lower than that of traditional industrial robots, and the working range is only similar to that of a human arm. Products with collaboration as the main technical feature, including single-arm collaborative robots, dual-arm collaborative robots, composite robots, mobile dual-arm collaborative robots, table tennis robots, etc.; among them, dual-arm collaborative robots have loads of 3kg and 5kg, single-arm collaborative robots Loads include 3kg, 5kg and 20kg. The product application of collaborative robots meets the needs of precision assembly, testing and human-machine joint operations. Currently, it is applied in the automotive, 3C, semiconductor, and medical fields, and involves welding and assembly in the production of electronic products. , Grinding, testing and other complex processes.
1、Collaborate with people and give full play to the advantages of people and robots
The "In-depth Research and Investment Prospects Report on China's Collaborative Robot Industry for 2020-2024" released by the China Investment Industry Research Institute shows that, compared with industrial robots that have been developed for decades, the biggest breakthrough of collaborative robots is that they can directly stand side by side with humans. Cooperation without using safety fences for isolation. This method not only reduces the distance between humans and robots, but also greatly reduces the area occupied by the workstations. More importantly, it can fully combine the advantages of humans and machines and learn from each other. , Let robots assist humans to complete those highly repetitive, high-precision tasks, while humans solve tasks with high flexibility and continuous optimization. When assembling high-precision heavy parts, human-machine collaboration highlights its advantage of combining the advantages of humans and machines.
2、High security
High safety is one of the basic characteristics of collaborative robots. At the beginning of its design, it aims to provide safety guarantee for human-machine interaction. Therefore, in order to realize the safety of human-machine collaboration, collaborative robots generally adopt lightweight designs, such as lightweight Body shape, application of endoskeleton design methods, etc.; limit operating speed and motor power; use joint torque sensors for contact detection, safety controller technology, etc. to ensure human safety, which is a way to avoid injury from the root cause the way.
3、Simple deployment, flexible and easy to use
Collaborative robots generally support dragging and teaching, equipped with intuitive user programming interface, integrated simple operation, easy-to-master software system and modular encoder, etc. Ordinary workers can pass certain training after unpacking in most places Many deployment tasks are completed, so deployment is simple.
In addition, the lightweight collaborative robot can be installed on a desktop or on a device, which is very flexible.
4、Lower cost
The cost of industrial robots generally includes both the price and deployment of the robot itself. The price of collaborative robots is generally 10-20w. Due to the characteristics of easy programming and installation, the cost of deployment is generally low. In addition, lightweight collaborative robots greatly reduce space requirements, which can reduce many installation and plant costs for enterprises.
An industrial robot used in mainstream occasions has a price range of 10w-40w according to the load capacity, and the cost of deployment is even higher, at least 2-3 times the price of the robot.
5、Support flexible production mode
The collaborative machine robot breaks through the limitation of the safety fence, and can be free from the constraints of a fixed geographic location. Instead, it can quickly adapt to new production tasks in different places with simple programming and training according to actual needs. Good support for flexible production mode. Even if a robot malfunctions, it can be quickly supplemented by a new robot.
