Detailed description of the preferred embodiment Referring to Fig.l and Fig.3, the automatically pairing unit for the magnet group comprises a NS poles conveyor track 1, an output track 2, a mounting bracket and a push assembly 3, the NS poles conveyor track 1 is arranged vertically, the output track 2 is arranged horizontally, the push assembly 3 is arranged to the position where the NS poles conveyor track 1 is vertical to the output track 2.

The permanent magnets within the NS poles conveyor track 1 move down /10 incessantly due to the effect of the gravity, by the pushing of the push assembly 3 the permanent magnets within the output track 2 are conveyed out incessantly with alternating polarities.

Referring to Fig.2, the NS poles conveyor track 1 comprises two opposed E-shaped tracks, the N pole conveyor track is made up by the upper half of the two E-shaped track, the S pole conveyor track is made up by the lower half of the two E-shaped track, the N pole conveyor track is parallel to the S pole conveyor track, and they are separated by the middle portion of the io E-shaped track.

Referring to Fig.l, the output track 2 comprises two opposed [-shaped tracks, the opposed arrangement may be from up to down, or may be from left to right, the embodiment takes the up-down for example.

Referring to Fig.4, the magnets within the N pole conveyor track have the same direction of the magnetic line, the magnets within the S pole conveyor track have the same direction of the magnetic line, the direction of the magnetic line of the magnets within the N pole conveyor track is opposite to 20 the direction of the magnetic line of the magnets within the S pole conveyor track. The direction of the magnetic line of the NS poles conveyor track 1 and the output track 2 are vertical to the conveying direction. A reciprocating push block 32 is arranged to the position where the NS poles conveyor track 1 is vertical to the output track 2, the direction of the 25 movement of the push block 32 is vertical to the conveying direction of the NS poles conveyor track 1, the direction of the movement of the push block 32 is aligned to the conveying direction of the conveyor track, the push 6/10 block 32 pushes the magnets fallen from the NS poles conveyor track 1 to the output conveyor track 2.

Referring to Fig.8 to Fig.9, the push assembly 3 comprises a base seat 31, a 5 push block 32, a connecting rod 34, a power input wheel 33, a support arm 35, a shaft 36, a sleeve 37, a bearing 38, an antiextrusion ring and a screw.

The push block 32 passes through the base seat 31, and slides fit with the base seat 31, the power input wheel 33 rotatably couples to the support arm 35, and rotates around its axis. The connecting rod 34 rotatably couples io to the eccentric portion ofthe push block 32 and the power input wheel 33.

In order to increase the efficiency and reliability of the rotary joint, the shaft 36 connects the power input wheel 33 and the connecting rod 34, the shaft 36 rotatably connects the connecting rod 36 and the push block 32, the is shaft 36 rotatably connects the power input wheel 33 and the support arm 35, between the shaft 36 and the support arm 35 is arranged two paratactic bearings 38 so as to form a transmission joint, obviously, the rotatable connection is achieved by the clearance fit between shaft and the hole.

The support arm 35 is removably mounted to the base seat 31 through crews, such structure is beneficial to assemble each part well so as to increase the compactness of the structure. The distance between parts are adjusted by the sleeve 37 so as to increase the flexibility of the transmission.

The NS poles conveyor track 1, the output track 2, the push block 32 and the base seat 31 are made of nonmagnetic material to avoid the influence of the magnetic force caused by the permanent magnets conveyed within the 7/10 tracks.

Referring to Fig.5 to Fig.7, each parts are assembled together according to the above, a connecting rod and slider mechanism is formed. A force is 5 exerted on the power input wheel 33, such as connecting the power input wheel 33 and the electric motor with a belt, the power input wheel 33 rotates, the rotation of the wheel 33 makes the connecting rod 34 swing, the swing of the connecting rod 34 make the push block 32 move, because of the limit of the base seat 31, the push block 32 moves only in a io reciprocating way, such that the power input wheel 33 rotates one round, the push block 32 moves from the totally stretched out position to the totally retracted position, and returns from the totally retracted position to the totally stretched out position. is During the push block 32 moving from the totally stretched out position to the totally retracted position, the permanent magnets within the NS poles conveyor track 1 falls in front of the push block 32 due to the effect of the gravity force. During the push block 32 moving from the totally retracted position to the totally stretched out position, the push block 32 pushes the 20 fallen magnets forward till the push block 32 moves to the totally stretched out position, during the course, the permanent magnets within the NS poles conveyor track 1 can not fall down because of the limiting effect of the upper surface of the push block 32; when the push block 32 is in the totally retracted position, the magnets within the NS poles conveyor track 1 fall down to wait for the next push from the push block 32. Because the NS poles conveyor track 1 separately conveys the permanent magnets with the same direction of magnetic line, and the directions of the magnetic line of 8/10 magnets within two tracks are opposite, the push block 32 pushes the two magnets with alternating polarities every time, the push block 32 reciprocatedly pushes the magnets, so the object of the invention is achieved, that is, the automatically pairing unit for the magnet group can correctly efficiently assemble a plurality of magnets in an alternating manner.

In order to increase the efficiency, a plurality of pairing units can be formed into an array, such as a rectangular array or a ring array, than taking the io array as a part of the assembly line.

The direction of the magnetic line in this invention means the direction of the magnetic line located inside the single permanent magnet.
