Embodiment
The automatic combo of a kind of magnetic pole group unit as shown in Figure 1,3, it comprises N, S delivery track 1, output track 2, fixed mount (not shown) and pushes assembly 3, N, S delivery track 1 vertically arrange, output track 2 is horizontally disposed with, and N, S delivery track 1 are provided with and push assembly 3 with output track 2 places of intersecting vertically.
Permanent magnet in N, S delivery track 1 is motion down continuously under Action of Gravity Field, and the permanent magnet on output track 2 is assembled and is output in the mode of magnetic pole alternative arrangement continuously under the propelling movement that pushes assembly 3,
As shown in Figure 2, N, S delivery track 1 are oppositely arranged by two " E " shape tracks, the first half of two " E " shape tracks forms N delivery track, and the Lower Half of two " E " shape tracks forms S delivery track, and N delivery track is parallel with S delivery track and separated by the middle part of " E " shape track.
As shown in Figure 1, " [" shape track is oppositely arranged output track 2, can adopt up and down and be oppositely arranged, and also can adopt left and right to arrange mutually by two.The present embodiment has adopted up and down and has been oppositely arranged.
As shown in Figure 4, the magnetic line of force direction of the permanent magnet in N delivery track is consistent, and the magnetic line of force direction of the permanent magnet in S delivery track is consistent, and with N delivery track in the magnetic line of force opposite direction of permanent magnet; The magnetic line of force direction of the permanent magnet on N, S delivery track 1 and output track 2 is vertical with its throughput direction; The direction of motion of pushing block 32 is vertical with the throughput direction of N, S delivery track 1, and consistent with the throughput direction of delivery track, and pushing block 32 is pushed to the permanent magnet dropping on N, S delivery track 1 on output track 2.
As Figure 8-9, push assembly 3 and comprise pedestal 31, pushing block 32, connecting rod 34, power input wheel 33, support arm 35, axle 36, axle sleeve 37, bearing 38, back-up ring (not shown) and screw (not shown);
Pushing block 32 runs through pedestal 31 and slidably coordinates with pedestal 31, and power input wheel 33 rotatably connects with support arm 35, and power input wheel 35 can be around its axis circular-rotation, and connecting rod 34 connects the eccentric part of pushing block 32 and power input wheel 33 rotationally.
In order to make to rotate connection high efficient and reliable, by axle 36, power input wheel 33 is connected with connecting rod 34, also by axle 36, connecting rod 34 is rotated and connected with pushing block 32, by axle 36, power input wheel 33 is rotated and connected with support arm 35, between axle 36 and support arm 35, relend and help 2 bearing 38 driving coupling side by side, obviously, rotatably connect to coordinate with the gap in hole by axle and realize.
Support arm 35 is removably mounted on pedestal 31 by screw (not shown), and such structure is conducive to realize the assembling capacity of each part, improves the compactedness of structure.The distance regulating between each part by axle sleeve 37, the flexibility that improves mechanism driving.By back-up ring (not shown), can make that each part is rotating to be linked together.
What transmit due to delivery track is permanent magnet, and for fear of the impact of magnetic force, N, S delivery track 1, output track 2, pushing block 32, pedestal 31 make for non-magnetic material.
As shown in Fig. 5-7, by above-mentioned mode, connect each part, can form a set of linkage rod slide block mechanism, give power input wheel 33 input powers, for example with belt, power input wheel 33 is connected with motor (not shown), can make power input wheel 33 rotate, power input wheel 33 drivening rods 34 swing, the connecting rod 34 swinging drives pushing block 32 motions, restriction due to 31, base, make pushing block can only do back and forth movement repeatedly, therefore power input wheel 33 rotates one week, can make pushing block 32 move to full retracted position from full extended position, by full retracted position, moving to full extended position.
When pushing block 32 moves to the process of full retracted position from full extended position, the permanent magnet on N, S delivery track 1 drops to the place ahead of pushing block under the effect of gravity; When pushing block 32 moves to the process of full extended position from full retracted position, pushing block 32 is pushing away two permanent magnets that fall down and is moving forward, until pushing block 32 moves to full extended position, in this process, permanent magnet on N, S track 1 cannot fall down due to the restriction of pushing block 32 upper surfaces, when the pushing block 32 full retracted position that moves back, the permanent magnet on N, S track 1 just can fall down, and waits for the propelling movement of next pushing block 32.Because N, S delivery track 1 are being carried the permanent magnet of the magnetic line of force in the same way separately, and the magnetic line of force of the permanent magnet on two delivery tracks is contrary, so pushing block 32 is each all at the permanent magnet that is pushing two magnetic pole alternative arrangements, pushing block 32 pushes repeatedly, can realize object of the present invention, automatic combo provided by the invention unit can efficiently and exactly be assembled a plurality of permanent magnets in the mode of magnetic pole alternative arrangement.
Above-described is structure and the operation principle of single automatic combo unit, in order to enhance productivity, a plurality of automatic combos unit can be formed to array, for example square array (see figure 10) or annular array (seeing Figure 11), then the part using these arrays as assembling line.
The magnetic line of force direction of the permanent magnet described in the application refers to the magnetic line of force direction of single permanent magnet inside.
