Please refer to FIG. 1, FIG. 2 and FIG. 6, and now the positioning device 100 provided by the present invention will be described. The alignment device 100 includes a pneumatic box 10 and an alignment mechanism 20, and the alignment mechanism 20 is connected to the pneumatic box 10. The air pressure box 10 is used to blow the plate 91 to be suspended on the air pressure box 10, and the air pressure box 10 can also blow the plate 91 to be transported forward on the air pressure box 10. The plate 91 moves in the forward conveying direction on the pneumatic box 10, from upstream in the forward conveying direction to downstream in the forward conveying direction. The board body 91 may be a circuit board, a circuit board, or other board parts that need to be transported. The alignment mechanism 20 is used to push the plate 91 suspended on the air pressure box 10 to move in a direction perpendicular to the forward conveying direction, so as to align the plate 91. The air pressure box 10 is provided with an air inlet pipe 13 so as to be connected with the air supply device 40 so as to supply air to the air pressure box 10 through the air supply device 40 to ensure the air pressure in the air pressure box 10. for The air device 40 may be external. Of course, in some embodiments, the air supply device 40 can also be integrated into the alignment device 100. The air supply device 40 may be a blower. Some gas supply devices 40 may also be compressed gas cylinders. Of course, in some industrial production, if a centralized gas supply source such as a cylinder, pipeline or compressor for supplying compressed gas is provided, the gas supply device 40 may also be the centralized gas supply source. The air pressure box 10 has a top plate 11, and the top plate 11 is provided with a plurality of exhaust holes 111.

The moving speed on the top plate 11 is too fast. When the inclination angle of the top plate 11 to the horizontal direction is less than 2 degrees, the forward conveying speed of the plate body 91, especially the initial speed, will be slower, which affects the conveying efficiency. When the inclination angle of the top plate 11 to the horizontal direction is greater than 4 degrees, the forward acceleration of the plate 91 will be too large, which will cause the plate 91 to advance on the top plate 11 too fast, and the positioning device 100 cannot push the plate 91 to move in alignment.
