Refer to the attached drawing 1 discloses a kind of flattening mechanism in pole piece substrate cockle region, and the flattening mechanism includes giving
The flattening device of pole piece base material flattening and the fixed frame I 4 for installing flattening device, the flattening device can be in fixation
Frame I 4 carries out axis rotation；
The flattening device includes at least two and is used for the first nip rolls 2 flattened to base material both sides and is located at
First nip rolls, 2 discharge end is used for the second nip rolls 1 flattened to base material middle part.It is mainly used in the present embodiment
The both sides of pole piece base material and middle part region are carried out open-top flattening by two groups of rollers, pole piece substrate tape are allowed to pass through roller twice, effectively
Using bulging rolling, material strip is made to prevent the secondary fold of pole piece through a nip rolls flattening so that subsequent laser in tight shape
Cutting is smooth, improves yields.
It employs two first nip rolls 2 in the present embodiment to flatten base material both sides, the two first flattenings
Roller 2 is with 1 center symmetric setting of the second nip rolls；The first nip rolls 2 is four in other embodiment, the first nip rolls 2 two
For one group, to be mutually arranged close between same group of the first nip rolls 2, and different groups is then with 1 central symmetry of the second nip rolls
It sets.
Further shown in refer to the attached drawing 1, first nip rolls 2 excessively becomes for diameter from centre to both ends are gradually gentle
Small circular roll structure.The circular roll structure that second nip rolls 1 gradually gently excessively becomes smaller for diameter from center to both ends.
The gradually smaller drum like structure roller in both ends broad in the middle is can be understood as, effectively the position of required flattening can be flattened,
Using the bulge-structure among drum like structure roller, make material strip in tight shape, effectively processing flattening, and use two groups of roller flattenings effective
Prevent the secondary fold of pole piece substrate tape so that subsequent laser cutting smoothly completes and greatly improves the yields of pole piece.
Further shown in refer to the attached drawing 1, the flattening mechanism is additionally provided with circle in the front end of the feed inlet of the first nip rolls 2
Columnar idler roller 3, the idler roller 3 are installed by fixed frame II 5, and fixed frame II 5 can be set to the root of activity
According to the idler roller 3 on the rate of tension demand adjustment fixed frame II 5 of base material.The idler roller 3 connects with the second nip rolls 1 for surface
It touches and tenses base material, and the S-type structure of base material.Pass through the effective pole piece substrate tape of the combination of tensioning wheel and the second nip rolls 1
Material can be tensed to greatest extent, and the flattening work of base material is effectively ensured.
Here it will be seen that being located between 3 and second nip rolls 1 of idler roller to compress base for first nip rolls 2
Material, idler roller 3 contact for surface with the second nip rolls 1 and tense base material.Here base material is through the bottom roll surface of idler roller 3 and second
The top roll surface of nip rolls 1, S-type tightening structure after idler roller 3 is connected base material with the second nip rolls 1, also allows for the second exhibition
Plain-barreled roll 1 can effectively flatten the centre of base material；Base material by the tension of 3 and second nip rolls 1 of idler roller is again
By the first nip rolls 2 by using the open-top fold of intermediate raised portion of drum assembling structure, base material both sides position is given so as to reach
It is flattened.
It is further shown in refer to the attached drawing 1,2, the axis center of first nip rolls 2 and the axis center of the second nip rolls 1
To be arranged in parallel.It is to be understood that for two the first nip rolls 2 axis on the same line, while first nip rolls 2
The axis of axis and the second nip rolls 1 is to be arranged in parallel, the effective efficiency for ensureing flattening base material.
Further shown in refer to the attached drawing 2, the diameter and length of first nip rolls 2 are both less than the second nip rolls 1
Diameter and length.Need exist for explanation is 1/2 of 2 diameter of the first nip rolls less than 1 diameter of the second nip rolls, and first
2 length of nip rolls is less than the 1/2 of 1 length of the second nip rolls.Both sides position is flattened by smaller the first shorter nip rolls 2,
Preferably local flattening effect, while use and be relatively large in diameter second nip rolls 1 longer with length to middle part can be played
It is flattened, can effectively prevent the base material after flattening from secondary fold occur, and laser cutting occurred and defective products occur, increased
Cost.
A kind of flattening equipment of pole piece base material is provided according to above-mentioned technical solution, includes above-mentioned pole piece substrate cockle
Region flattening mechanism, the feed inlet of the above-mentioned pole piece substrate cockle region flattening mechanism further include the blowing of base material material
The laser cutting device of the discharge outlet of equipment and above-mentioned pole piece substrate cockle region flattening mechanism.It is right that this flattening equipment passes through
Material strip before laser cutting carries out flattening processing, efficiently solves because of the fold of pole piece base material, and laser cutting lug is caused to be cut not
It is disconnected, so as to cause broken belt, the problem of pole piece is caused to scrap, while efficiency and cutting yield when improving laser cutting, it is promoted
Product quality.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
