[0065] During the tool recovery process, the management personnel put the tool into the recovery material port 24, and the tool is detected by the detection camera 251 in the screening mechanism 25. When the tool can be reused, the rotating shaft 2521 controlled by the reduction motor rotates clockwise to transfer the tool placed in the placement slot 2522 on the material guide partition 2523 to the recovery material guide belt, and the tool is transferred to the tool recovery device 14 for recovery through the recovery material guide belt. When it can no longer be used, the scrap rotating shaft 2521 rotates counterclockwise to transfer the tool to the recovery box at the bottom of the rotating shaft 2521. In the tool recovery device 14, the driving motor in the displacement mechanism 141 drives the longitudinal screw rod 1411 and the transverse screw rod 1413 to control the movement of the first wire sleeve 1412 and the second wire sleeve 1414 respectively, thereby controlling the movement of the position of the material guide mechanism 142 installed on the second wire sleeve 1414, so that it corresponds to the position on the tool storage rack 12. After the laser calibration mechanism 1424 provided at the end of the U-shaped material guide groove on the material guide mechanism 142 is calibrated with the laser receiving mechanism 1425 provided on the tool storage rack 12, the spring push rod 1422 in the material guide mechanism 142 pushes the tool out, and the material guide slope 1423 at the exit of the U-shaped guide groove 1421 can facilitate the tool to slide into the tool storage rack 12.
