The hopper disc 2 is provided with a spiral ascending track 22, the track 22 is tightly attached to the side wall of the hopper disc 2, the pulse electromagnet and the spring piece enable the hopper disc 2 to vibrate, and then workpieces in the hopper disc 2 are vibrated to ascend along the track 22 in a spiral mode; when the chassis 21 vibrates, the workpiece 1 on the chassis 21 can spirally move from inside to outside along the track 22, the width of the track 22 is larger than the width of the workpiece 1 and smaller than the length of the workpiece 1, so that the workpiece 1 sequentially passes and advances along the track in the broadside direction, and the workpiece in the long side direction automatically falls out of the track and enters the chassis 21 again, thereby realizing the preliminary orientation of the workpiece in the long-and-wide direction. The rail 22 includes a first torsion portion 221, a second torsion portion 222, and a third torsion portion 223, the first torsion portion 221 torsion the rail 22 from a horizontal plane to a nearly vertical inclined plane, and the workpiece 1 passes through the first torsion portion 221 and then obliquely contacts the rail 22; the track 22 is provided with a baffle plate 23 protruding upwards at the initial end of the first torsion part 221, the baffle plate 23 extends in an arc along the track 22 towards the direction of the surface taking assembly 3, the baffle plate 23 plays a role in guiding the movement of the workpiece, and the workpiece sequentially enters the first torsion part 221 along the baffle plate 23.
The second twisting part 221 twists the rail 22 from the inclined surface to a horizontal surface, and then moves the workpiece 1 horizontally onto the measuring device 6.

Because the distances from the front surface and the back surface of the workpiece to the first photoelectric sensor 31 are different, the light intensity values reflected by the front surface and the back surface of the workpiece are different, the first photoelectric sensor 31 can detect which surface of the workpiece 1 abuts against the track 22 according to the light intensity reflection value of the workpiece 1, and send the detection result to the central controller, the central controller is connected with the first electromagnetic valve, the central controller controls the first electromagnetic valve to open or close according to the detection result of the first photoelectric sensor 31, when the window opening surface of the workpiece 1 abuts against the track, the first electromagnetic valve is opened, the first air blowing port 32 blows the workpiece over, and otherwise, the first electromagnetic valve does not act. The track 22 is provided with a flat surface 224 at the position of the surface taking assembly 3, and the tail end of the material baffle 23 is terminated in front of the flat surface 224; the work piece with the window facing against the rail is subjected to the air pressure of the first air blowing port 32, and then the window facing is laid down on the flat surface 224.
