Abstract
The utility model discloses a coating structure of lithium ion battery roll core, which belongs to the field of lithium ion batteries. The utility model aims at providing the coating structure of lithium ion battery roll core, which has low cost and high manufacturing efficiency. The coating structure comprises a lithium ion battery roll core, and termination glue on the battery roll core is connected with bottom glue into a whole. The coating structure has low cost, high manufacturing efficiency, easily controlled character and mature technique, is easy to be produced and applied in batch, and is suitable for the manufacturing field of lithium ion batteries.
Description
Technical field
The utility model relates to a kind of volume cored structure of lithium ion battery, in particular, relates to a kind of lithium ion battery coil core rubberizing structure.
Background technology
In the prior art, along with the continuous application of lithium-ion electric pool technology and produce perfect, production technology is progressively optimized improvement in operation, but, it is the mode of stop adhesive, bottom glue, top glue that rubberizing structure on present shell with square aluminum inside lithium ion cell volume core adopts three rubberizings substantially, because of need paste three gummed papers, thereby flow chart is more; Primer and spacer ring glue need adopt manual work, and homogeneity of product and quality can be under some influence, and cost of labor is bigger.So the flow chart that present shell with square aluminum lithium ion battery rubberizing structure is caused is various, cost of labor is high, the unsettled technological deficiency of homogeneity of product, become those skilled in the art's technical problem anxious to be solved.
Summary of the invention
Technical purpose of the present utility model is, operation is many in process of production, cost is high, the technical problem of homogeneity of product difference to overcome the volume core rubberizing structure of lithium ion battery in the prior art, and the lithium ion battery coil core rubberizing that a kind of cost is low, production efficiency is high structure is provided.
A kind of lithium ion battery coil core rubberizing structure includes lithium ion battery coil core; Stop adhesive on the described battery roll core and bottom glue are connected as a single entity.
In the one side of described bottom glue, be provided with the hot melt adhesive-layer;
Described stop adhesive and glue junction, bottom are provided with folding trace.
In the utility model, in process of production, the electric core after coiling finished presses core to handle, and when pressing core, it is bonding that high temperature makes the bottom glue that extends out on volume core bottom and the stop adhesive carry out nature, forms firm bottom glue; Play the effect of protection volume core bottom; The utility model adopts mechanical work, has guaranteed each consistency of product.
The beneficial effects of the utility model are: because the operation of bottom glue is sticked in cancellation, directly reduce personnel cost, and adopt the rubberizing operation of mechanization, improved the consistency of rubberizing; And stop adhesive and bottom glue are connected as a single entity, and have more guaranteed the sealing effectiveness of electric core side; The utility model is simple to operate, and quality control is easy, and technology maturation is easy to mass production applications.
Description of drawings
Fig. 1 is the structural representation among embodiment of the utility model, and stop adhesive 4 extends certain length among the figure, as bottom glue 41.
Embodiment
In conjunction with the accompanying drawings 1, in the structure of ion battery volume core of the present utility model rubberizing, lithium includes lithium ion battery coil core, and the stop adhesive 4 on the described battery roll core is connected as a single entity with bottom glue 41.In process of production, the electric core after coiling finished presses core to handle, and when pressing core, it is bonding that high temperature makes volume core bottom carry out nature by the bottom glue 41 that extends out on the stop adhesive, forms firm bottom glue; Play the effect of protection volume core bottom; The utility model adopts mechanical work, has guaranteed each consistency of product.Include battery cathode ear 1, anode ear 5 and volume core 3, on battery roll core 3, post top glue 2, and post stop adhesive 4 on the volume core 3 and by stop adhesive on the bottom glue 41 that extends; In production process of the present utility model, select for use half-automatic winder that the volume core is carried out winding work, guarantee to roll up the core quality consistency.In conjunction with the half-automatic winder functions of the equipments, when the bag stop adhesive, make encapsulate length around volume core one week of width after device parameter is regulated, and stop adhesive gummed paper width exceed about volume core bottom 5mm; See 41 places among Fig. 1; Electric core after coiling finished presses core to handle, and when pressing core, high temperature makes that to be in the bottom glue 41 that volume core bottom extends out bonding naturally with the bottom, plays protective effect bottom the volume core simultaneously.Battery behind the pressure core posts top glue by technology.Saved the operation of pasting bottom glue; To roll up extended bottom, core bottom glue 41 first side direction when going into shell on one side, will roll up core retainer plate again and go into enclosure interior.This top has no effect to employee's operating efficiency.Follow-uply get final product by the normal process operation.One side at described bottom glue 41 is provided with the hot melt adhesive-layer, is used for bottom glue and battery case are pasted; Described stop adhesive 4 and bottom glue 41 junctions are preset with folding trace, are used to adapt to the battery corner.
Structural design of the present utility model can be saved bag primer operating personnel fully, directly reduces operating cost.Stop adhesive 4 around volume one week of core, has been guaranteed the quality of electric core avris, avoided because of going into the improper volume core avris gummed paper breakage that causes of shell.The mechanization operation is adopted in the stickup of stop adhesive 4 fully, has guaranteed the attractive in appearance complete and consistency of volume in-core portion.
