Description
Technical field
The utility model relates to battery production equipment technical fields, specifically, being rectified a deviation before being related to a kind of pole piece coiling
Device and the cylindrical battery core film-making up- coiler for being provided with deviation correcting device before the pole piece coiling.
Background technique
The battery core of battery is by the way that positive plate, negative electrode tab, diaphragm etc. are wound system according to certain order layer poststack
At, and technology relative maturity is rolled to battery core at present, and the production of battery core also substantially can be by rolling equipment reality
Existing automated production, so that the winding quality of battery core and winding precision have obtained effective guarantee, and can also be substantially
The production efficiency of the raising battery core of degree reduces the rework rate of cost of labor and battery core production.
And in the coiling process of battery core, the height of battery core degree of registration can directly impact the quality of battery core, in addition,
Battery core degree of registration is also to judge an important indicator of battery core quality quality.Currently, existing core coil control equipment is in the market
Guarantee the degree of registration of battery core, pole piece can go out setting up procedure deviation correction mechanism on core coil control equipment is come to pole piece tape transport during
Existing offset is corrected.But existing process deviation correction mechanism can only be realized and is inserted into positioned at pole piece unreeling structure and pole piece
Pole piece between mechanism carries out positional deviation correction, i.e., can only rectify a deviation to the pole piece during tape transport.And since battery core is carrying out
When winding, need to clamp pole piece to winding head by pole piece interposer, make winding head to positive plate, negative electrode tab, diaphragm into
Row winding, and during this makes pole piece interposer be clamped, be moved to pole piece and pole piece is connect with winding head,
During winding head is to pole piece, membrane winding, pole piece is easy to appear double offset so that battery core roll during battery core pair
Qi Du is reduced, and process correction at this time is can not to rectify a deviation to pole piece.
In addition, battery core, when being wound, pole piece easily deviates, so that the degree of registration of battery core reduces, and at this time
Process deviation correction mechanism can not timely rectify a deviation to pole piece.Furthermore existing process deviation correction mechanism is largely by one
Swingable correction frame rectifies a deviation to pole piece, i.e., when pole piece deviates, by error correct frame swung come so that
Pole piece carries out " snakelike " mobile, and then realizes and rectifies a deviation to pole piece, but there are the correction precisions low, correction of such correction mode
The disadvantages of speed is slow, offset is difficult to control.Also, traditional core coil control equipment is when being wound, and is inserted by pole piece
Enter at the winder station that mechanism clamps pole piece to winding head, then pole piece one is gone forward side by side by the way by way of only rolling up diaphragm
Row winding, and have no traction mechanism auxiliary pole piece and be driven, this makes during electric core winding, and pole piece is easy due to tension

Partially.
The course of work of cylindrical battery core film-making up- coiler is as follows:
When pole piece insertion cutting means 103 are in feeding state, firstly, the first driving mechanism of the first hold-down mechanism 34
341 driving third roll shafts 342 are mobile backwards to the first roll shaft 32, the second driving mechanism 341 driving the 4th of the second hold-down mechanism 34
Roll shaft 342 is mobile backwards to the second roll shaft 33.
Then, pole piece is delivered to the winder station of winding head 102 by the insertion unit 1031 of pole piece insertion cutting means 103
Place, so that the volume at the winder station of winding head 102 is clamped for pole piece, and is ready for rolling for battery core.
After pole piece is sent at the winder station of winding head 102 by insertion unit 1031, insertion unit 1031 is resetted.
Meanwhile first first driving mechanism 341 of hold-down mechanism 34 to drive third roll shaft 342 mobile towards the first roll shaft 32, and then make
Pole piece between the first roll shaft 32, third roll shaft 342 is pressed together on the first roll shaft 32 by third roll shaft 342；Second compresses
