When the photoelectric RFID performs detection and identification, the four pillars 211 are installed with cameras 212 that can take a comprehensive picture of the surroundings of the object to be detected to find the identification tag. The cameras 212 with equal distances can conveniently use the taken photos to find the coordinate position of the identification tag through an algorithm.

[0029] Furthermore, the sliding assembly 22 includes a pulley 221, a wheel plate 222, a motor 223, a screw 224, a wheel frame 225 and a nut 226. The pulley 221 is installed on the outer side of the groove 214, the wheel plate 222 is installed on one side of the pulley 221, the motor 223 is installed on the other side of the wheel plate 222, the screw 224 is arranged on the top end of the wheel plate 222, the wheel frame 225 is installed on the outer side of the screw 224, and the nut 226 is installed on the outer side of the wheel frame 225. When the photoelectric RFID performs detection and identification, the coordinate position of the identification tag is found through an algorithm based on the photo taken by the camera 212, and the motor 223 drives the pulley 221 to rotate, and drives the wheel frame 225 to rotate along the inner wall of the top plate 213 to the detection position.

[0030] Furthermore, the groove 214 and the pulley 221 are movably connected, and a pair of pulleys 221 are symmetrically arranged on the upper and lower sides of the groove 214, and a pair of pulleys 221 are symmetrically arranged on the left and right sides of the vertical center line of the wheel frame 225, and are movably connected to the inner wall of the top plate 213.
