The system of this application also includes: a 12 station rotating bearing silo, a 24 station automatic push-pull steering platform, and multiple types of tooling grippers. The robot sequentially grabs the turning knots that need to be processed on the 24 station automatic push-pull turning knot platform by dismantling the stack, and moves them to the laser printer for automatic marking. After completion, move to the rotating bearing silo at position 12 to retrieve the bearings. This bearing silo is a fully automated equipment that can directly rotate and lift the bearings to a fixed position. After the robot grasps the bearing, it interacts with the machine tool signal to place the steering joint and bearing to be processed, controls the machine tool to press them, and flows into the next workstation along the assembly line. The entire system efficiently coordinates with the production pace of the assembly line to meet user requirements. And save 50% of labor costs, while alleviating the problems of high repetition and difficulty in recruitment in this process. At the same time, for such heavy and irregularly shaped workpieces, Ruiyi Intelligent's solution has successfully avoided potential injuries to employees during the production process.
