Aiming at the problem of low efficiency of tile fixing in concrete precast construct (PC) producing line at present, parallel robot is used for fixing tile on the outside wall firstly. The automatic tile fixed technique was analyzed, and the automatic equipment solution for the tile fixing was put forward. The feasibility of the solution is proved by the data of efficiency, accuracy, and strength which is gotten from the experiment of the automatic equipment solution of snatching and fixing tiles by robot.
