Research on Defects and Positioning Inspection of Spiral Sand Core Based on Visual
There is a high temperature working environment in the low-pressure casting production of new energy vehicle water-cooled casings,and there is a certain risk and high labor intensity during the artificial lower core;the defect and positioning detection methods are lacked during robot lower core,which can easily cause local damage to the sand core and result in internal structural defects and blocked spiral water channels in the casting structure.In view of this,visual equipment was installed,robot specific fixtures were de-signed,robot vision workstations and control systems were constructed,and visual schemes for sand core defect detection,placement and positioning detection and robot work schemes were planned.The robot simulation verification software RobotStuio was used to verify the robot vision workstation.After detecting collisions,optimizing path and modifying program,the lower core action program of the robot was compiled and optimized.The purpose of the robot placing the spiral sand core intact and accurately on the mold base of the low-pressure casting equipment is achieved,the intelligent control level,product quality and production efficiency of low-pressure casting of new en-ergy vehicles water-cooled casings are improved,it also provides a solution for the application of the same type of vision robot.
