Abstract As a basic component, bearing has a wide variety and is in great demand in industrial production. For the convenience of users, bearings with different materials at both ends must be sorted before packaging, so that the end faces with the same materials orientate the same direction. At present, most domestic bearing manufacturing enterprises still use manual sorting method, which is inefficient. In order to improve the sorting speed of bearing and reduce the cost of manufacturing enterprises, taking the 608-Z type bearing as an example, starting from the design goal of fast and convenient sorting the bearing, a bearing end face detection and sorting device was innovatively designed, which used the PLC (programmable logic controller) as the control core, the color code sensor as the main sensing element, and the cylinder and the electric rotary table as the main actuator. This device distinguished the orientation of the bearing end face through the color recognition, and controlled the turnover and arrangement of the bearing through the cylinder, which realized the detection and sorting of the bearing. The bearing end face detection and sorting device based on color recognition had the characteristics of fast recognition, simple and reliable mechanical structure and stable operation, which could realize the detection of the bearing end face and the sorting of the bearing. The test results show that the designed device can meet the actual bearing production needs, which can provide a reference for encouraging the transformation and upgrading of bearing manufacturing enterprises and promoting the gradual implementation of unmanned chemical factories.
