Abstract
The utility model relates to a pole piece protective device for lithium ion battery which consists of a broach winded by the pole piece, and two armor plates protecting the pole piece which winds the broach. The aforementioned two armor plates are fixed on the two sides of the broach. The utility model of armor plates can protect the broach side edge and effectively enhance the fail-safe reliability of the battery.
Description
Technical field
The utility model relates to lithium ion battery and makes the field, relates in particular to a kind of electrodes of lithium-ion batteries protective device that in the lithium ion battery manufacture process pole piece is shielded.
Background technology
In recent years, along with the automaticity of lithium rechargeable battery manufacturing improves day by day, pole piece is to have enough to meet the need with the form of volume after reeling in each operation of film-making process, the two sides of pole piece volume are easy to damage because of collision in circular flow, the damage at pole piece edge then directly influences the pole piece quality, the pole piece edge that the back is damaged thereby the electricity core is shaped very easily pierces through barrier film and causes electric core short circuit, badly influences the security performance of battery.For how making pole piece injury-free in each operation of film-making, also there is not effective solution at present.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of electrodes of lithium-ion batteries protective device that in the lithium ion battery manufacture process pole piece is shielded.
For solving the problems of the technologies described above; the technical scheme that the utility model adopted is: a kind of electrodes of lithium-ion batteries protective device is provided; described protective device comprises for the reel of pole piece coiling, and to being wound in pole piece volume side on the reel along the two block protection plates that shield, described two block protection plates can be fixed in described reel both sides by fixture.
Reel of the present utility model is cylindric, and two block protection plates are discoideus.
Reel both ends of the surface of the present utility model are provided with positioning boss, and described two block protection plate centers are provided with the centre bore that cooperates with described positioning boss.
Fixture between reel both ends of the surface of the present utility model and the two block protection plates is respectively 2-4.
Be provided with several heat transfer holes on the two block protection plates of the present utility model.
Fixture of the present utility model is a snap close; it comprises the snap close ring that is set in turn in fixed head, spring, the portable plate in the reel end face counterbore and is positioned at baffle opposite position place; described fixed head is fixed in the place, aperture of counterbore; described portable plate is movably set in the counterbore; described spring places between fixed head and the portable plate, and described portable plate is set to cam surface towards the one side of spring.
Fixture of the present utility model can also for screw, and reel and baffle on the screwed hole that is provided with of corresponding position.
The beneficial effects of the utility model are: because the utility model is by respectively being provided with a baffle in reel both sides; when pole piece coiling has enough to meet the need on reel; two block protection plates can be to the both sides of pole piece volume along shielding, and are can be because of collision etc. not former thereby pole piece is sustained damage.Thereby guaranteed the fail safe of pole piece quality and battery effectively.

Fig. 1 is the utility model electrodes of lithium-ion batteries protective device user mode figure;
Fig. 2 is the utility model electrodes of lithium-ion batteries protective device exploded view (not containing fixture);
Fig. 3 is the snap close exploded view among the utility model electrodes of lithium-ion batteries protective device embodiment 1.
Embodiment
Embodiment 1:
See also Fig. 1,2; the utility model electrodes of lithium-ion batteries protective device comprises for the reel 3 of pole piece coiling, and to being wound in pole piece volume side on the reel 3 along the two block protection plates 1 that shield, described two block protection plates 1 can be fixed in described reel both sides by snap close 4.
This reel 3 is cylindric, and two block protection plates 1 are discoideus, and reel 3 both ends of the surface are provided with positioning boss 31, and described two block protection plates 1 center is provided with the centre bore that cooperates with described positioning boss 31.
Snap close 4 between reel both ends of the surface and two block protection plates is set to 3 respectively, and evenly distributes along the reel both ends of the surface.
Be provided with several heat transfer holes 5 on the described two block protection plates 1.
See also Fig. 3; described snap close 4 comprises the snap close ring 41 that is set in turn in fixed head 42, spring 43, the portable plate 44 in the simple end face counterbore of volume and is positioned at baffle opposite position place; described fixed head 42 is fixed in the place, aperture of counterbore; described portable plate 44 is movably set in the counterbore; described spring 43 places between fixed head 42 and the portable plate 44, and described portable plate 44 is set to cam surface towards the one side of spring 43.
When baffle 1 is installed; baffle 1 is passed through the circle hole sleeve at its center on the positioning boss 31 of reel 3; snap close ring 41 on the baffle 1 is inserted in the portable plate 44 by the fixed head 42 on reel 3 end faces, spring 43; the rotation lock clasp 41 then; portable plate 44 also rotates thereupon; and the compression of the cam surface on the portable plate 44 spring 43, thereby snap close ring 41 is compressed to fixed head 42, baffle 1 just is pressed on the pole piece reel 3 simultaneously.During dismounting baffle 1, rotate three snap close ring 41 handles respectively, just baffle 1 and reel 3 can be separated.
Embodiment 2:
In this embodiment; described reel, baffle structure are identical with embodiment 1; fixture adopts screw; in reel both ends of the surface and baffle corresponding position four screwed holes are set evenly; when baffle is installed; respectively screw is screwed in four screwed holes, and during the dismounting baffle, only need four screws are screwed out respectively and get final product.
