Specific embodiment
Due to the difference of each manufacturer's production technology, polymer lithium electricity in the market is divided into takeup type (Sony, Toshiba
To represent), stacked (TCL, ATL are representative) two kinds of different structures.
Existing laminating machine and lamination principle are all successively video discs, i.e. using a continuous barrier film, by barrier film using folded
Piece machine carries out Z-shaped bending, and positive plate and being implanted in barrier film interlayer for negative plate interval are formed lamination, and this mode works
Inefficiency, although automaticity can be improved, is still difficult to meet efficient production.
Common mentality of designing is to improve the feeding efficiency of barrier film, i.e. using continuous, the continuous film feeding of high speed, carried
High production capacity.
But traditional method is defective, problem is, when film feeding speed is reached after 1 meter per second, as barrier film has
Certain elasticity, certainly exists restoring force, causes stress during high-speed coiling, i.e. the lamination after winding, electrode can be wrapped up in
Tightly, cause buckling phenomena.
For existing defect, the subject matter of the present invention is as follows：
Exploitation is the continuous lamination process of a kind of pair of barrier film, and theoretically, efficiency improves and should be single-layer septum and continuously fold
It is more than the twice of piece.
Exploitation is a kind of safe and efficient continuous lamination process, positive plate and the completely isolated encapsulation of negative plate, improves encapsulation
Quality.
Its basic principle is, by the way of two-layer separator is superimposed simultaneously, will be positive plate therein or negative plate pre-
First it is superimposed between two barrier films, preliminary encapsulation is carried out by heat seal then, is then folded over, replanted in folding process
Enter another negative plate or positive plate, form compound lamination effect, be packaged lamination is formed after arrangement.
While folding, heat sealing can be carried out to the barrier film of first overlapping so that positive/negative plate is isolated from each other, and carries
High isolation effect between the two.
Simultaneously for the lamination speed of high speed, traditional sucking disc type mechanical hand cannot adapt to quick, continuous positive plate
Or the supply of negative plate, the carrying part of electrode slice is redesigned, to reaching the purpose of global optimization.
Based on the description above, a kind of lamination machinery of the offer that the present invention is provided：As shown in Fig. 1 to Figure 20,
Including barrier film release part 1, positive plate release part 2, heat sealed portion 3, negative plate release part 4, finishing part
5th, folded portion, reduction part 6 and transport portion.
Barrier film release part 1 includes the first barrier film relieving mechanism 11, the second barrier film relieving mechanism 12, barrier film release part
Effect is to carry out discharging, flatten, tile the barrier film of rolling with rational sequence one after another and speed.
Wherein the first barrier film relieving mechanism 11 is made up of let off roll 111, idler roller 112 and nip rolls 113, and the second barrier film is released
Laying mechanism is identical with the first barrier film relieving mechanism.
Wherein the first barrier film relieving mechanism 11 first discharges the first barrier film 11 ', after tiling, then discharges positive plate, then discharges
Second barrier film 12 ', positive plate A is encapsulated between two-layer barrier film, and is positioned, and finally carries out heat seal, forms being interrupted, equal
Even spaced positive plate, the spacing between two of which positive plate are arranged on 2 millimeters, and 2 millimeters of the interval is logical
Cross what electronic dividing plate was realized.
Membrane unwinding roller 111 is adopted determines torque buffer technology, i.e. the motor of let off roll 111 is servo digitalization electricity
Machine, can be digitized control, enter row buffering using determining moment device, determine power between let off roll 111 and motor power axle
Moment device structure includes：Inside and outside two nylon jackets 1111 being nested with, realize determining torque by the damping force arranged between nylon jacket
Transmission, under normal circumstances, keeps friction law, geo-stationary when driving torque exceedes setting torque, to realize between nylon jacket
Skid, prevent what excessively transmission from causing to barrier film excessively to tear, with reference to Fig. 7.
Idler roller 112 is using flexible tensioner technology, i.e. idler roller is a composite roll, and middle mandrel is steel shaft, steel shaft
Outer surface is set to quality of rubber materials, and mandrel two ends are arranged in frame by bearing.
Used as a kind of replaceable scheme, above-mentioned idler roller is the composition of flexible axle and rubber sleeve, and in the appearance of flexible axle
Face covers rubber sleeve, wherein, barrier film is unclamped by rotating, prevents tension in R2 rice by the curvature control of idler roller.Installing
