Abstract
The utility model relates to a lithium ion battery high-compaction ratio positive pole piece roller press. The device comprises an upper roller and a lower roller which are arranged on a supporting seat in parallel in the vertical direction, wherein the lower roller is provided with a plurality of annular platforms along the circumferential direction of the lower roller, and the setting positions of the platforms correspond to the blank leaving positions of the pole pieces. According to the above technical scheme, the utility model discloses a position that corresponds the pole piece and leaves white under the roller sets up the platform to fill the pulling force difference, can solve fold, disconnected problem in area, the platform can also compensate coating and the regional difference in height of not coating simultaneously, and this roll squeezer can realize the industrial production of high-compression ratio battery.
Description
Technical field
The utility model is related to field of lithium ion battery, and in particular to a kind of lithium ion battery high-pressure solid is than anode pole piece roller
Press.
Background technology
At present, it is in the production process of ternary NCM111 battery samples to use roll unit or the roller with flattening mechanism more
Press.During using roll unit, because frequent fold, broken belt can not be produced；During using roll squeezer, blank space is same in rolling process
There is the problem of fold, broken belt can not be produced in batches.Ternary material is due to material property and technological requirement high-pressure solid ratio（3.3）, pole piece exists
There is very big extension in compacting process, so needing very big smoothing wrinkle tension force, actual test is not less than 1000N.Due to using
Larger smoothing wrinkle tension force, has material pole piece and is left white position by the power stretching of larger difference, enter to unreel glue in pole piece so result in
The position that roller and home roll go out pole piece easily wrinkles, corrugation will broken belt, directly contribute pole piece and scrap, using the said equipment not
Product can be made.
Utility model content
The purpose of this utility model is to provide a kind of lithium ion battery high-pressure solid than anode pole piece roll squeezer, the roll squeezer
The problem of fold, broken belt can be solved, and industrialization production of the high-pressure solid than battery can be realized.
To achieve the above object, the utility model employs following technical scheme：Including being arranged in parallel in above-below direction
Upper roller and lower roll on support base, described lower roll are circumferentially provided with the platform of multiple ring-types, the setting position of the platform along it
Put with pole piece to be left white position corresponding.
The height of the platform subtracts the thickness of aluminium foil for the half of pole piece compacted depth, and the width of the platform is pole piece
The width being left white.
The edge of the platform is provided with a diameter of 1~2mm lead angle.
Described platform and lower roll global formation.
Described platform is embedded on lower roll using polytetrafluoro or copper strips.
As shown from the above technical solution, the utility model sets platform by the position being left white in lower roll correspondence pole piece, with
Filling-in variation in tension, it is possible to resolve the problem of fold, broken belt, while platform can also compensate for the height of coating and non-coatings area
Difference, the roll squeezer can realize industrialization production of the high-pressure solid than battery.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model lower roll.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of lithium ion battery high-pressure solid as shown in Figure 1 is than anode pole piece roll squeezer, including in the parallel cloth of above-below direction
Upper roller 2 and lower roll 3 on support base 1 are put, lower roll 3 is circumferentially provided with the platform 4 of multiple ring-types, the setting position of platform 4 along it
Put with pole piece to be left white position corresponding.
Further, the height of platform 4 subtracts the thickness of aluminium foil for the half of pole piece compacted depth, and the width of platform 4 is
The width that pole piece is left white.The height of platform 4 should be controlled strictly, because podium level is too low not to have smoothing wrinkle effect, podium level
It is too high to be directly pressed onto aluminium foil, cause broken belt.
Further, the edge of platform 4 is provided with a diameter of 1~2mm lead angle.Edge material is uneven during due to production, or
Person's width, so setting lead angle to avoid expecting area in the edge of platform 4, prevents overvoltage in the change of the margin of tolerance.
Further, platform 4 and the global formation of lower roll 3, or platform 4 are embedded on lower roll 3 using polytetrafluoro or copper strips.
In summary, the utility model sets platform by the position being left white in lower roll correspondence pole piece, poor with filling-in pulling force
It is different, it is possible to resolve the problem of fold, broken belt, while platform can also compensate for the difference in height of coating and non-coatings area, the roll squeezer
Industrialization production of the high-pressure solid than battery can be achieved.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, on the premise of the utility model design spirit is not departed from, and those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of the utility model claims determination
In the range of.
