Referring to fig. 1, fig. 2 and fig. 6, an alignment apparatus 100 provided in the present application will now be described. The alignment device 100 comprises an air pressure box 10 and an alignment mechanism 20, wherein the alignment mechanism 20 is connected with the air pressure box 10. The pneumatic box 10 is used for blowing the plate body 91 to be suspended on the pneumatic box 10, and the pneumatic box 10 can also blow the plate body 91 to be conveyed forwards on the pneumatic box 10. The plate 91 moves on the pneumatic box 10 in the forward transport direction from upstream to downstream in the forward transport direction. The board 91 may be a circuit board, a circuit board or other board requiring transmission. The aligning mechanism 20 is used for pushing the plate body 91 suspended on the pneumatic box 10 to move along the direction perpendicular to the forward conveying direction so as to align the plate body 91. The air supply tube 13 is provided on the air pressure tank 10 to be connected to the air supply device 40 so that air is supplied to the air pressure tank 10 through the air supply device 40 to secure the air pressure in the air pressure tank 10. The gas supply means 40 may be external. Of course, in some embodiments, the gas supply device 40 can also be integrated into the aligning device 100. The air supply device 40 may be a blower. Some of the gas supplies 40 may also be compressed gas cylinders. Of course, in some industrial production, if a centralized gas supply source such as a gas cylinder, a pipeline, or a compressor for supplying compressed gas is provided, the gas supply device 40 may be the centralized gas supply source. The pneumatic box 10 has a top plate 11, a plurality of exhaust holes 111 are opened on the top plate 11, the plate body 91 is suspended on the top plate 11 by the airflow blown out through the plurality of exhaust holes 111, and the plate body 91 is blown to move forward for transmission.

Compared with the prior art, the aligning device 100 provided by the application has the advantages that the exhaust holes 111 are formed in the air pressure box 10, so that the blowing plate body 91 is suspended on the top plate 11, and the blowing plate body 91 moves forwards for transmission; the alignment mechanism 20 is arranged to push the plate body 91 suspended on the top plate 11 to move so as to align the plate body 91, and the plate body 91 is suspended on the top plate 11, so that the plate body 91 can be prevented from being scratched when the plate body 91 moves forwards, is transported and is aligned to move; when the alignment device 100 is used for carrying out transmission alignment on the circuit board, the circuit board can be prevented from being scratched, and the quality of the circuit board is prevented from being influenced.

In one embodiment, referring to fig. 1 and 2, the top plate 11 is disposed obliquely to the horizontal direction, and the height of the upstream position of the top plate 11 along the forward conveying direction is greater than the height of the downstream position of the top plate 11 along the forward conveying direction, that is, the top plate 11 is inclined downward along the forward conveying direction, so that the body can move downstream along the forward conveying direction under the action of gravity when the body is suspended on the top plate 11, so as to realize forward conveying.

In the above embodiment, referring to fig. 1 and 2, the inclination angle of the top plate 11 with respect to the horizontal direction is 2-4 degrees, so that the plate body 91 can advance on the top plate 11 for transportation, and the plate body 91 can be prevented from moving on the top plate 11 too fast. When the angle between the top plate 11 and the horizontal direction is less than 2 degrees, the forward conveying speed, especially the initial speed of the plate 91 is slow, and the conveying efficiency is affected. When the inclination angle of the top plate 11 and the horizontal direction is greater than 4 degrees, the forward acceleration of the plate 91 is too large, so that the forward speed of the plate 91 on the top plate 11 is too fast, and the alignment device 100 cannot push the plate 91 to move for alignment.

In one embodiment, the inclination angle of the top plate 11 is 3 degrees from the horizontal direction, so as to ensure good forward conveying of the plate body 91 on the top plate 11, facilitate the aligning device 100 to push the plate body 91 to perform aligning movement, and ensure the forward conveying speed of the plate body 91.

In one embodiment, referring to fig. 4 and 5, the inclination angle a between the axis M of the exhaust hole 111 and one end of the top plate 11 ranges from 82 degrees to 90 degrees, and one end of the top plate 11 is the end of the top plate 11 located at the downstream of the exhaust hole 111 in the forward moving conveying direction; that is, the inclination angle a between the axis M of the exhaust hole 111 and the end of the top plate 11 downstream of the exhaust hole 111 in the forward moving direction is 82 to 90 degrees, and the inclination angle a between the axis M of the exhaust hole 111 and the normal direction of the top plate 11 is 0 to 8 degrees, so that the airflow blown out from the exhaust hole 111 is inclined toward the downstream of the forward moving direction, so that the airflow blown out from the exhaust hole 111 can push the plate body 91 to move forward and transmit. The inclination angle a between the axis M of the exhaust hole 111 and the top plate 11 is 82-90 degrees, so that the plate body 91 can be ensured to move forward and transmit on the top plate 11 well. If the inclination angle a between the axis M of the exhaust hole 111 and the top plate 11 is smaller than 82 degrees, the plate 91 moves on the top plate 11 too fast, and the alignment device 100 cannot push the plate 91 to move. When the inclination angle a between the axis M of the exhaust hole 111 and the top plate 11 is greater than 90 degrees, it is difficult to blow the plate body 91 forward.

In one embodiment, when the top plate 11 is disposed obliquely to the horizontal direction, the axis N of the exhaust hole 111 may be disposed perpendicular to the top plate 11, and at this time, the axis N of the exhaust hole 111 is oblique to the vertical direction and is inclined to the forward direction, so that the blowing plate 91 may be advanced.

In one embodiment, the inclination angle a of the axis N of the exhaust hole 111 and the end of the top plate 11 downstream of the exhaust hole 111 in the forward moving direction is 3 degrees, so that the plate 91 can be blown forward on the top plate 11, and the alignment mechanism 20 can push the plate 91 to move in alignment.

In one embodiment, referring to fig. 3, the plurality of air vents 111 are arranged in a rectangular array to facilitate manufacturing, and the structure can make the air vents 111 uniformly distributed to make the plate 91 uniformly stressed when the plate 91 is blown.

In one embodiment, the exhaust holes 111 are tapered to provide a greater pressure to the blown air, thereby facilitating the floating support of the plate body 91 on the top plate 11.

In one embodiment, the exhaust hole 111 may also be cylindrical to facilitate manufacturing.

In an embodiment, referring to fig. 3, a buffer area 110 is disposed on the top plate 11 at a position corresponding to the downstream of the forward conveying direction, the alignment mechanism 20 is located at a position corresponding to the buffer area 110, and a plurality of air blowing holes 112 are formed in the buffer area 110, so that the plurality of air blowing holes 112 can blow an air flow blown out from the upstream of the forward conveying direction, and when the plate body 91 reaches the buffer area 110, the air flow blown out from the air blowing holes 112 can blow the plate body 91 to move at a reduced speed, so that the alignment device 100 pushes the plate body 91 to move in alignment.

In one embodiment, referring to fig. 4 and 5, the inclination angle b between the axis N of the air blowing hole 112 and the other end of the top plate 11 is 82-86 degrees, and the other end of the top plate 11 is the end of the top plate 11 located at the upstream of the air blowing hole 112 in the forward conveying direction. That is, the range of the inclination angle b between the axis N of the blowing hole 112 and the top plate 11 at the end of the blowing hole 112 close to the upstream of the forward conveying direction is 82-86 degrees, and the range of the inclination angle b between the axis N of the blowing hole 112 and the normal direction of the top plate 11 is 4-8 degrees, so that the air flow blown out from the blowing hole 112 inclines towards the upstream of the forward conveying direction, when the plate body 91 moves forward above the top plate 11, the air flow blown out from the blowing hole 112 can decelerate the plate body 91, so that the alignment device 100 pushes the plate body 91 to move perpendicular to the forward conveying direction, so as to align the plate body 91. If the inclination angle b between the axis N of the blowhole 112 and the end of the top plate 11 on the upstream side of the blowhole 112 in the forward conveying direction is larger than 86 degrees, it becomes difficult to decelerate the plate body 91 or the plate body 91 is decelerated too slowly. If the inclination angle b between the axis N of the blow hole 112 and the end of the top plate 11 on the upstream side of the blow hole 112 in the forward conveying direction is smaller than 82 degrees, the plate body 91 is decelerated too fast, and even moves in the reverse direction.

In an embodiment, referring to fig. 4 and fig. 5, the range of the inclination angle b between the axis N of the air hole 112 and the other end of the top plate 11 is 85 degrees, that is, the inclination angle b between the axis N of the air hole 112 and the normal direction of the top plate 11 is 5 degrees, so that the speed of the plate body 91 can be reduced, and the alignment device 100 can push the plate body 91 to perform alignment movement conveniently.

In one embodiment, each of the blowing holes 112 is tapered so that the blowing air pressure is high, thereby facilitating the floating support of the plate body 91 on the top plate 11.

In one embodiment, the blowing holes 112 may also be cylindrical to facilitate manufacturing.

In one embodiment, referring to fig. 3, the plurality of air blowing holes 112 are arranged in a rectangular array to facilitate processing, and the structure can make the air blowing holes 112 uniformly distributed to make the plate body 91 uniformly stressed when the plate body 91 is blown.

A position-limiting plate 31 is provided, and when the plate body 91 advances to the end, the position-limiting plate 31 can stop the baffle body 91 to position the plate body 91, so that the alignment mechanism 20 pushes the plate body 91 to move for alignment.

In an embodiment, referring to fig. 1 and fig. 3, by the cooperation between the buffer area 110 and the limiting plate 31, when the plate body 91 moves forward to the buffer area 110, the plate body 91 is decelerated by the buffer area 110 and then stopped and positioned by the limiting plate 31, so as to better protect the plate body 91.

In one embodiment, a cushion pad may be disposed on the position limiting plate 31 to play a role of buffering to protect the plate body 91.

In one embodiment, the aligning apparatus 100 further includes a sensor 32 for detecting whether the plate 91 reaches the aligning mechanism 20, wherein the sensor 32 is mounted on the pneumatic box 10; therefore, the plate body 91 moves forward on the pneumatic box 10, and when the sensor 32 detects the plate body 91, the aligning mechanism 20 can push the plate body 91 to move so as to align the plate body 91.

In one embodiment, referring to fig. 1 and 2, the alignment mechanism 20 includes a flap sheet 21 for pushing the sheet 91 to move along a direction perpendicular to the forward conveying direction, a flap driver 22 for driving the flap sheet to move, and a fixing seat 23 for supporting the flap driver 22, the fixing seat 23 is installed on the air pressure box 10, and the flap sheet 21 is installed on the flap driver 22; the clapper piece 21 is pushed to move by the clapper driver 22, so as to push the plate body 91 to move perpendicular to the forward conveying direction, and then the plate body 91 is aligned.
