Today, more and more collaborative robots appear on the car production line to help manufacturers implement more intelligent and flexible manufacturing processes.Create a healthy and safe working environment for employees;At the same time, it can effectively improve production efficiency, and human-machine collaboration will become the trend of the future.Bent le automotive industry corporation is one of the leading supplier of global auto parts matching products for almost all automobile manufacturers in the world, including the front suspension, after the suspension module, chassis system and other parts.In bent le Schwandorf factory is located in Germany, with nearly 600 robot, the robot's main job is in a security fence welding of auto parts, except only one robot - FANUC CR - 35 ia collaboration robot, it does not require security fence.
In order to guarantee the quality of the product, bent le will be scheduled for the finished product quality inspection on the production line, including the anticollision structure products, need the product in the process from transport and handling operations between 6.The single weight of the product is about 14kg. For bulk inspection, manual handling is very strong.For this purpose, we introduced cr-35ia to perform efficient man-machine collaboration, and the cr-35ia completed the heavy lifting and loading work, while the person completed the inspection and labelling work.To improve efficiency, the cr-35ia USES two modes of work: high-speed working mode and collaborative working mode.With the safety laser scanner, the cr-35ia can automatically switch between the two working modes of high speed and collaboration.In high-speed mode, the maximum movement speed of robot can reach 750mm/s.When a person close to the robot, the safety laser scanner detects people into robots in within the scope of work, the robot will be from the operating mode switch to the collaborative operation mode, to ensure the safety of the people.Under the cooperative mode, the maximum movement speed of the robot is 250mm/s.In addition, in the process of the operation, if the robot encounters a human, or a person encounters a robot, the robot will automatically stop the action and avoid causing harm to the person.The robot also has a 2D camera on hand to locate the location of the product that needs to be moved.
In addition to auto parts production, the whole car factory also has fewer cr-35ia.Dongfeng nissan is one of the earliest factories in the country to introduce cr-35ia collaborative robots, where cr-35ia is affectionately known as "little green".At the beginning of 2016, the day since the little green came into the world, engineers have been given an unparalleled mission -- a new attempt to collaborate on the production line to improve manufacturing efficiency and precision.
Little green can be like a man has the ability of self learning and imitation, simple handling operations, for example, engineers just hold little green handle, will carry the goods movement again, little green can be recorded, next time do not need to repeat teaching will be able to move their own, abandoned the traditional robot programming steps repeat, maximum load and robot reached 35 kg, is one of the largest collaborative robot load in the world today.
In addition, the working precision of the small green is quite high, and the repeatability can reach positive and negative 0.04 mm.Combined with high security, the operator can work with it without any burden. As a working partner, little green can be pretty reliable.At dongfeng nissan, future little green may be engaged in intelligent assembly, handling, assisted welding and other related work. Currently, both the handling and auxiliary welding operations have been successfully tested.
Safe, efficient and able to give full play to the human-machine advantages of collaborative robots will be the trend of the future, and we believe that there will be more and more small green in the future.
