Example one
As shown in fig. 3, the utility model provides a utmost point ear rubberizing mechanism, utmost point ear rubberizing mechanism includes utmost point ear rubberizing mechanism and utmost point ear rubberizing mechanism down, it is used for the rubberizing to the side on utmost point ear 10 to go up utmost point ear rubberizing mechanism, it is right that utmost point ear rubberizing mechanism is used for down utmost point ear downside rubberizing, go up utmost point ear rubberizing mechanism and utmost point ear rubberizing mechanism all includes down: the adhesive tape unwinding assembly 51, the adhesive tape cutting assembly 55, the adhesive tape pulling assembly 57 and the adhesive tape pasting assembly 56;
the adhesive tape unwinding assembly 51 comprises an adhesive tape and is used for unwinding the adhesive tape in the whole operation process;
the adhesive tape cutting assembly 55 is positioned on one side edge of the adhesive tape unwinding assembly 51, and comprises a cutter for cutting the adhesive tape;
the glue pulling assembly 57 is positioned at one side edge of the glue cutting assembly 55 and used for pulling the cut adhesive tape to a preset position to prepare glue;
the rubberizing assembly 56 is located on one side of the tab pulling assembly 57, and is used for attaching the adhesive tape to be glued to the tab 10.
The working principle of the tab rubberizing mechanism is as follows: firstly, preparation is provided for the rubberizing of the tab 10, the required adhesive tape is placed in the adhesive tape unreeling assembly 51, the tab 10 to be rubberized is placed in the middle of the upper side and the lower side of the tab rubberizing mechanism, the tab 10 is unreeled and driven, one side of the tab 10 can be unreeled, and the other side of the tab 10 can be reeled; secondly, the whole operation of the tab gluing mechanism is started, the adhesive tape unwinding assembly 51 discharges the adhesive tape to provide unwinding of the adhesive tape for the whole operation process, the adhesive tape discharged is cut by the adhesive tape cutting assembly 55 through the cutter, the size of the cut adhesive tape is a preset size, and the adhesive tape cut by the adhesive tape pulling assembly 57 is pulled to a preset position to realize adhesive tape preparation; finally, the rubberizing assembly 56 attaches the adhesive tape with glue at a preset position to the side surface of the tab 10; and the upper tab gluing mechanism and the lower tab gluing mechanism operate simultaneously to adhere the upper side surface and the lower side surface of the tab 10 to the adhesive tapes.
The pole lug rubberizing mechanism optimizes a coating process in the prior art, improves the production efficiency of the pole lug 10 by utilizing a rubberizing process, and simultaneously realizes full-automatic operation of pole lug rubberizing; the die cutting procedure is optimized, the processing of reinforcing ribs 11 on the tab is not needed, and the integral manufacturing process of the tab 10 is simplified; the adhesive tape with low cost is used for replacing ceramic slurry with high cost, so that the manufacturing cost of the tab 10 is reduced; meanwhile, the tab rubberizing mechanism is simple in structure, easy to prepare, easy to operate, easy to maintain and high in practicability.
As an example, the tab gluing mechanism includes the upper tab gluing mechanism and the lower tab gluing mechanism, and is used for gluing two sides of a tab 10 of a pole piece, the upper tab gluing mechanism is identical to the lower tab gluing mechanism, and is used for gluing the upper side and the lower side of the tab 10 together, and the upper tab gluing mechanism and the lower tab gluing mechanism can be arranged in a completely symmetrical manner or in an asymmetrical manner.
When go up utmost point ear rubberizing mechanism and during utmost point ear rubberizing mechanism complete symmetry set up down, the simultaneous operation is right during the attached sticky tape of utmost point ear 10, the side is attached simultaneously about utmost point ear 10, but the sticky tape of side is perhaps had the phenomenon of part dislocation to take place about utmost point ear 10, leads to the rubberizing precision not enough, the sticky tape asymmetry on utmost point ear 10 two sides can not coincide, causes utmost point ear 10 decline in quality.
