In order to pursue greater flexibility and greater efficiency in the spraying process, the automotive industry began to introduce robots instead of spraying machines since the 1990s, and began to use robots for automatic spraying of inner surfaces.
 
           Compared with the traditional mechanical spraying, the use of robotic spray has two outstanding advantages: can reduce the number of about 30% to 40% of the gun; improve the speed of the gun movement. In order to adapt to high-speed spraying, in the inner surface coating and the second layer of metal paint spray should use high-speed rotating spray gun.
 
          The rapid development of the modern automobile industry brings rapid changes in the car model and the continuous adjustment of the body design, only the use of robots to adapt to this frequent changes in the production requirements. The role of the robot is to control the spray gun, so that in the spraying process and spray the surface to maintain the correct angle and constant distance (usually 200mm). In order to achieve this task, engineers use specialized software to spray the object of the three-dimensional model to deal with the gun to determine the movement path and the corresponding spray parameters. And then transfer these data to the robot controller, in the entire spraying process control robot action. In general, only in the more complex and requires a very accurate spraying process only need to deal with this.
 
          In the growing awareness of environmental protection today, people call the good environmental protection coating plant for the "green factory", the old technology for the "brown factory". Whether it is a new green factory or the transformation of brown factories, the establishment of automatic robot spraying production line is very necessary. In the new plant, the rational use of funds is the most important principle, so reduce the spray production line is a very critical part of the investment. And for those who need to transform the factory, how to properly introduce the robot into the existing coating production line, and the resulting costs are the key issues. The
  
          The design of the new generation of coated robots implements the principle of modular construction, the robot can be equipped with different connection devices, so that both can work in a fixed way can also be installed in orbit work. The track can be fixed on the side wall of the spray chamber, or it can be fixed near the ceiling. If the spraying robot spray gun into the operating fixture, it becomes a robot to open the door, because the two kinds of robot drive system is the same.
 
         The movement of the robot arm can be selected to fit into two or three axes. The biaxial robot cooperates with a high-speed rotating gun to operate in a rotationally symmetrical way of motion, which reduces the drive shaft, reduces weight, and simplifies the design.
         
         Robot spraying work has three main modes: the first is the dynamic / static mode, in this mode, the spray material is first sent to the spray chamber, in the spraying process to remain static. The other is the flow pattern, in which the spray is uniformly passed through the spray chamber. The robot can be moved in the dynamic / static mode, and the robot is fixed in the flow mode. The third mode is the tracking mode, in which the spray is uniformly passed through the spray chamber, the manipulator not only tracks the spray, but also changes the direction and angle according to the spray surface.
 
         In the outer surface of the spraying process, the robot placed in the ascending orbit, can be free to close the surface of the spray, so you can reduce the operating space, reduce operating costs. In the transformation of the old factory, if in this way with the robot to replace the old machine, you can keep the original spray room unchanged. This will reduce the cost of transformation, but also shorten the duration. In the inner surface spray chamber, the tracks of different robots can be installed in parallel. The operating robot for opening the hood and trunk cover is placed on a higher track so that it can "work" across the spray robot placed on the lower track. This program can make the spray room shortened 1 ~ 2m, both to reduce construction investment, but also reduce operating costs.
 
          The robot's power supply, controller and safety system are installed in the control box outside the spray. As the control box also uses a modular design, it can be very convenient for the customer's actual coating process to optimize the configuration. In the advanced coating system produced by Toure, a multi-motion flexible control technology is used to integrate the control of the robot and the control of the spray process together without the need to set the control of the spray process.

          As the working environment of the spraying workshop is harsh, the spraying robot has made the attention of many employing units upon birth. With the new labor law to strengthen the protection of laborers, the legal protection consciousness of laborers is strengthened, and the popularization of spraying robots is an inevitable trend The
