From to realize the adjusting to diaphragm position, realization correction.Specifically, the second deviation correction mechanism 720 includes pedestal, two groups of deviation rectification rollers
And power source, two groups of deviation rectification rollers are arranged at intervals on pedestal, two groups of deviation rectification rollers are located at the top of lamination stacking table 600, also, two groups are entangled
Inclined the distance between roller and lamination stacking table 600 are unlikely to excessive, to guarantee that the diaphragm after the correction of the second deviation correction mechanism 720 can
It directly falls on lamination stacking table 600, and then guarantees the position precision of diaphragm；Further, diaphragm can be clamped in two groups of corrections
In interval between roller, and deviation rectification roller can be moved along it axially with respect to pedestal, the output end of power source and two groups of deviation rectification rollers
Transmission connection, as a result, under the driving effect of power source, the related diaphragm clamped between the two of two groups of deviation rectification rollers can be along entangling
The axial direction (diaphragm width direction) of inclined roller is mobile, to realize second of correction to diaphragm.Herein it should be noted that second entangles
Inclined mechanism 720 can also be other structures mode, the prior art can also be referred to, as long as can be realized to diaphragm deviation rectifying effect i.e.
Can, concrete mode is unrestricted.
In addition to above scheme, static elimination mechanism 800 is set also before stacking mechanism 500, to eliminate due to diaphragm
The electrostatic for rubbing and generating between each roller, to avoid the problem that influencing lamination due to electrostatic.
In the present embodiment, lamination process after one layer of diaphragm is completed, places pole piece specifically, on lamination stacking table 600；It is putting
While setting pole piece, one section of diaphragm that cache mechanism 300 releases unreeling structure 100, which caches, (it is past from a left side to cache roller 322
It is right)；Pole piece is put rear stacking mechanism 500 well and is turned to diaphragm, and new one layer is spread；When beginning, since lamination roller 522 can be slightly remote
From lamination stacking table 600, to guarantee that pole piece can be placed into, as a result, can one section of diaphragm of redundancy, the diaphragm of this section of redundancy can first by
The recycling of cache mechanism 300 (caching roller 322 is from left to right), when lamination roller 522 starts new one layer of paving close to 600 diaphragm of lamination stacking table
When, cache mechanism 300 releases the diaphragm (caching roller 322 turn left from the right side) cached, facilitates stacking mechanism 500 to release
This section of diaphragm is taped against on pole piece；After one layer of new diaphragm is completed, new pole piece is placed, at the same time, cache mechanism 300 again will
One section of diaphragm that unreeling structure 100 releases caches (caching roller 322 is from left to right), and so on, it is final to realize that Z-type is folded
Piece.
