Description
Technical field
The utility model relates to lithium ion battery coating machine device, relate in particular to a kind of novel lithium ion battery coating machine device.
Background technology
As everyone knows, the coating machine live-rollers that is used for lithium ion cell electrode coating mostly is whole cylindrical, smooth surface, smooth; Receive the restriction of traditional coating machine live-rollers shape, structure, not only can not select dispensing area, and complicated follow-up lug welding sequence; Production costs such as equipment and operation have been increased; Even cause the folding of pole piece, fracture, problem such as rolling is uneven, ring the normal running of subsequent handling, more even cause performance issues such as finished product battery internal short-circuit, self discharge are big.
The utility model content
Existing problem when being coated with to above-mentioned prior art lithium ion battery; The utility model provides a kind of not only can control the selection dispensing area; But also can simplify the novel coating machine device of operations such as later welded lug; This device has not only reduced the production cost of equipment and operation, and reduced the folding of coating paillon foil, fractureed, probability that problem produces such as rolling is uneven, performance issue such as finished product battery internal short-circuit, the self discharge of also having avoided causing because of painting process is big.
The technical scheme that the technical problem that the utility model will solve is taked is: the coating machine device of said new type lithium ion battery comprises roller 1, profiling piece, spring, air-leg, suction air extractor, electrical control gear, doctor roll, roller 2 and hopper; Said profiling piece is connected in spring one end; The said spring other end is connected on the air-leg; Said air-leg is controlled by electrical control gear, and said suction air extractor is controlled by electrical control gear, and said profiling piece, spring, air-leg, suction air extractor, electrical control gear all are arranged on the roller 1; Said profiling piece can be done stretching motion through spring; Said roller 2 is set in parallel in roller 1 left side, and said doctor roll secured in parallel is directly over roller 1, and said hopper is fixed on roller 1 upper right side.
During the utility model work,, slurry is coated on the paillon foil through roller 1, roller 2 and the not motion in the same way of material loading paillon foil.When coating was carried out, roller 1 adhered to the surface through rotating with slurry in the hopper, and when roller 1 moved to doctor roll scraper place, scraper was evenly distributed on roller 1 surface with slurry; When the not coating paillon foils that invest roller 2 surface turn to the left side that adheres to slurry roller 1, slurry will be applied on paillon foil, can be through the thickness of adjustment roller 1, roller 2 spacings adjustment coating paillon foil.When coating process proceeds to the non-welding electrode ear of paillon foil place, by the spring of air-leg control the profiling piece to be propped, profiling piece outer surface and roller 1 are removed profiling piece other surfaces partly and are combined into a smooth integral body; When coating proceeds to paillon foil soldering polar ear place, by the spring of air-leg control the profiling piece is regained, on roller 1, form one recessed; Controlling slurry with this is not coated on the paillon foil; Simultaneously, in the moment that the profiling piece is regained, the suction air extractor siphons away the slurry on the profiling piece outer surface; Guarantee the pure of slurry with this, the paillon foil that coating is accomplished gets into baking oven and dries.The design of the outer narrow inner width of said profiling piece is more conducive to the flexible of profiling piece, and the suction action of the expanding-contracting action of said profiling piece and suction air extractor guarantees the degree of accuracy in the regional and non-coating of paillon foil coating zone all through electrical control gear control with this.
The utility model when coating process carries out, can be controlled coating zone and non-coating zone owing on roller 1, adopted the design of movable profiling piece flexibly; Non-coating zone is used for the welding of follow-up lug, compares with existing technologies, has omitted laser and has scraped the lug operation; Increased battery capacity, saved equipment cost, safety and environmental protection; And reduced the phenomenons such as folding, fracture of scraping lug operation pole piece, guaranteed the quality of pole piece, avoided above-mentioned operation to produce the probability that reduces battery performance.
Description of drawings
Fig. 1 is a structural representation of the present invention.In the drawings, 1 is paper tinsel material volume, and 2 are material loading paillon foil not, and 3 is that roller 1,3.1 is the profiling piece, and 3.2 is spring; 3.3 be air-leg, 3.4 are the suction air extractor, 3.5 is electrical control gear, and 4 is hopper, and 5 is barrel; 6 is slurry, and 7 is doctor roll, and 8 is roller 2,9 is material loading paillon foil, and 10 is baking oven.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In Fig. 1; Said new type lithium ion battery coating machine device comprises roller 1 (3), profiling piece 3.1, spring 3.2, air-leg 3.3, suction air extractor 3.4, electrical control gear 3.5, doctor roll 7, roller 2 (8) and hopper 4; Said profiling piece 3.1 is connected in spring 3.2 1 ends, and said spring 3.2 other ends are connected on the air-leg 3.3, and said air-leg 3.3 is by electrical control gear 3.5 controls; Said suction air extractor 3.4 is by electrical control gear 3.5 controls; Said profiling piece 3.1, spring 3.2, air-leg 3.3, suction air extractor 3.4, electrical control gear 3.5 all are arranged on the roller 1 (3), and said profiling piece 3.1 can be done stretching motion through spring 3.2, and said roller 2 (8) is set in parallel in roller 1 (3) left side; Said doctor roll 7 secured in parallel are directly over roller 1 (3), and said hopper 4 is fixed on roller 1 (3) upper right side.
