Cooperative robot is a popular robot segmentation industry in recent years. Cooperative robot is a kind of robot that can interact / contact with human directly and safely. It has expanded the attribute of "human" in the connotation of robot function and has certain independent behavior and cooperation ability. It can be said that cooperative robot is the most tacit partner of human beings in the unstructured environment, The cooperative robot can cooperate with people and finish the assigned work safely.
Cooperative robots are easy to use, flexible and safe. Among them, ease of use is a necessary condition for the rapid development of cooperative robots in recent years, flexibility is a necessary prerequisite for the widespread application of cooperative robots by human beings, and security is the basic guarantee for the safety work of cooperative robots. These three main characteristics determine the important position of cooperative robots in the field of industrial robots, and their application scenarios are broader than traditional industrial robots.
At present, no less than 30 robot manufacturers at home and abroad have launched cooperative robot products, and introduced cooperative robots to the production line to complete precision assembly, detection, product packaging, grinding, machine tool loading and unloading. The following is a brief introduction to the top ten application scenarios of cooperative robots.
1. Packing and stacking
Packaging and palletizing is one of the applications of cooperative robots. In traditional industry, it is a kind of labor with high repeatability to dismantle, stamp and palletize. The use of cooperative robots can replace manual work to carry out the unpacking and palletizing of packaging boxes alternately, which is conducive to improving the order and production efficiency of goods stacking. Firstly, the robot unpacks the packing box from the tray and puts it on the conveying line. When the box reaches the end of the conveying line, the robot absorbs the box and stacks it on another tray.
2. Grinding and polishing
A flexible intelligent floating grinding head with force control technology is installed at the end of cooperative robot, which keeps constant force for surface grinding through pneumatic device. The application can be used for grinding various kinds of rough parts in manufacturing industry. According to the requirements of the process, rough grinding or fine grinding can be carried out for the surface roughness of the workpiece, and the grinding speed can be constant. According to the size of the contact force of the grinding surface, the grinding track can be changed in real time to make the grinding track adapt to the curvature of the workpiece surface, and the material removal amount can be well controlled.
3. Drag Teaching
The operator can directly pull the cooperative robot to reach the specified pose or move along the specific trajectory by manual traction, and record the pose data during the teaching process, so as to teach the robot application tasks in an intuitive way, which can greatly shorten the programming efficiency of the cooperative robot in the application deployment stage, reduce the requirements for the operator, and achieve the purpose of cost reduction and efficiency increase.
4. Gluing and dispensing
Collaborative robot instead of human's work for glue coating, engaged in a large workload, and fine workmanship, good quality. According to the program, he can automatically dispense glue and complete the planning path. He can control the amount of glue applied according to the set requirements to ensure even glue delivery. It is widely used in the automotive parts industry, 3C electronics industry and other scenes requiring glue application.
5. Gear assembly
The force control assembly technology of cooperative robot can be applied to gear assembly in automobile gearbox. In the process of assembly, firstly, the position of the gear in the loading area is sensed by the vision system, then the gear is grabbed and assembled. In the assembly process, the force sensor senses the degree of fit between the gears. When the weak effect between the gears is detected, the gears are accurately placed in a fixed position to complete the assembly of the planetary gears.
6. System welding
In the current market, excellent manual welders have become very scarce. It is a priority for many factories to replace manual welding with cooperative robot welding. According to the characteristics of the flexible trajectory of the robot manipulator, the arm swing amplitude and precision are adjusted, and the gun cleaning and wire cutting system is used to eliminate the blockage of the welding gun and reduce the consumption and time-consuming in the manual operation process. The welding system of cooperative robot has high precision and repeatability, which is suitable for long-term production process and can ensure the consistency of product quality. The programming operation of welding system is very easy to start, even the personnel who lack of operation experience can complete the programming of welding system programming system within half an hour, meanwhile, the program can be saved and reused, greatly reducing the training cost of new employees.
7. Screw lock
In the application of human labor-intensive assembly, the cooperative robot realizes precise screw locking through precise positioning and recognition, which has strong production flexibility and advantage characteristics. It can replace the automatic device of manual screw taking, placing and tightening, and can meet the needs of intelligent locking process of enterprises.
8. Quality inspection
High quality inspection and more accurate production batch can be obtained by using cooperative robot. Through the quality inspection of parts, including the overall inspection of finished parts, the high-resolution picture inspection of precision machined parts, and the comparison and confirmation of parts and CAD models, the quality inspection process can be automated and the inspection results can be obtained quickly.
9. Equipment care
A cooperative robot can maintain multiple machines. The nursing cooperative robot requires I / O docking hardware for specific equipment. These hardware prompts when the robot will enter the next cycle of production or when it needs to supplement raw materials, liberate labor and improve production efficiency.
10、 Remote monitoring
Collaborative robots also have applications in the field of remote security and monitoring, which combine different technologies, including mobile robots, sensors and video surveillance. These cooperative robots can be used in large open areas, such as farms, solar power stations, warehouses, airport parking lots or military bases, for remote security monitoring. When someone intrudes, alarm and response measures should be taken immediately, such as "professional security".
In addition to the above, cooperative robots are also used in other non manufacturing and non-traditional fields such as processing operations, medical surgery, warehousing logistics, machine maintenance, etc. With the development of artificial intelligence, cooperative robots will become more and more intelligent, will take on more responsibilities in many fields, and become an important human assistant.
