By heating simultaneously compression electrodes 30 and partition board 40 when the transmission unit C movements of such as conveyer belt etc in the state of overlapping each other,
So that electrode 30 and partition board 40 are engaged with each other.
Roller component 10 generally have cylindrical shape with using its centre rotational axis centered on rotation while compression by
The electrode 30 and partition board 40 of transmission unit C movements.
Here, when electrode 30 and partition board 40 are compressed, roller component 10 is heated to heating and compression electrodes 30 and partition board
40, to make coating to the adhesive melts of partition board 40, to make electrode 30 be bonded to partition board 40.
As shown in Figure 1 to Figure 3, according to one embodiment, can in the surface of roller component 10 depiction portion 20, with
When roller component 10 compresses partition board 40 and electrode 30, joint portion 31 and disengaged portion 33 are formed on electrode 30 and partition board 40.
However, according to another embodiment, can on the surface of roller component 10 embossing pattern portion 20.
That is, when 10 compression electrodes 30 of roller component and partition board 40, only the protruding portion on the surface of roller component 10 can press
Contracting electrode 30 and partition board 40 are to form joint portion 31 and disengaged portion 33, and at joint portion 31, electrode 30 is with partition board 40 by roller
The compression of component 10 is engaged with each other, and at disengaged portion 33, electrode 30 does not engage each other with partition board 40 because roller component 10 is not pressed
Contracting electrode 30 and partition board 40.
Here, when drafting department 20 is engraved, a part of compressible electrodes 30 in addition to drafting department 20 of roller component 10
With partition board 40.When drafting department 20 is embossed, 20 compressible electrodes 30 of drafting department and partition board 40.
With 1 μm to 5 μm of difference in height between drafting department 20 and the surface of roller component 10.
When the difference in height between drafting department 20 and the surface of roller component 10 is less than 1 μm, although provided with drafting department 20, but
It is the whole surface that electrode 30 and partition board 40 are transferred into for the load of compression electrodes 30 and partition board 40, accordingly, it is difficult in electricity
Disengaged portion 33 is formed between pole 30 and partition board 40.
In addition, when the difference in height between drafting department 20 and the surface of roller component 10 is more than 5 μm, compared to 1 μm to 5 μm
Difference in height, it is difficult to the drafting department 20 being not significantly different on manufacturing effect, and also manufacturing cost and temporal efficiency decline.
As described above, in the electrode assembly manufactured by roll squeezer according to the present utility model, the electrolysis of secondary cell
Matter can successfully be moved via disengaged portion 33 between electrode 30 and partition board 40.
Hereinafter, it will be described in detail a kind of laminating method using roll squeezer according to the present utility model.
Fig. 5 is the flow chart for sequentially illustrating the laminating method for using the roll squeezer according to the utility model embodiment.
As shown in Figure 5, using the laminating method of roll squeezer according to the present utility model include pattern forming step (S1),
Transfer step (S2) and compression step (S3).
As shown in Figures 1 and 2, pattern forming step (S1) be in the surface of roller component 10/surface on formed and have
The step of drafting department 20 of scheduled depiction or embossing pattern.
As shown in Figure 4, transfer step (S2) is transmitted each other by using the transmission unit (C) of such as conveyer belt etc
The step of electrode 30 of overlapping and partition board 40.
Compression step (S3) be heated and compressed by using roller component 10 electrode 30 transmitted by transmission unit (C) and every
The step of plate 40.
Here, when the adhesive melts of coating to partition board 40, it is bonded to by the partition board 40 that roller component 10 heats and compresses
Electrode 30.Here, the engaging force between electrode 30 and partition board 40 can be according to the position for the drafting department 20 being formed on roller component 10
And change, thus, only the subregion of electrode 30 and partition board 40 can be compressed and be engaged with each other.
In the electrode assembly manufactured as described above, joint portion 31 and disengaged portion 33 can be formed, it is electric at joint portion 31
Pole 30 is engaged with each other with partition board 40, and electrode 30 does not engage each other with partition board 40 at disengaged portion 33, to by joint portion
31 while keep the engaging force between electrodes 30 and partition board 40 so that electrolyte is by disengaged portion 33 in electrode 30 and partition board
It is successfully flowed between 40.
As described above, according to the utility model, due to forming drafting department on roller component to be formed on electrode and partition board
