Description

Technical Field

[0001] This utility model belongs to the field of lithium battery manufacturing, and in particular relates to a device for preventing aluminum coils from shaking. Background Technology

[0002] Aluminum foil for power lithium-ion batteries is typically produced by melting and then casting into 11±1mm thick aluminum coils. These coils are then annealed, cooled, and cold-rolled in 2-3 passes to obtain aluminum sheets with a thickness of 1.5-3.5mm. Due to the rough edges of the cast aluminum coils during the forming process, and the hardness and cracking nature of the cast material, a high breakage rate occurs during subsequent aluminum foil production, impacting production efficiency and significantly increasing production costs. Therefore, edge trimming is performed before foil rolling. However, current edge trimming devices do not secure the aluminum coils on both sides, leading to frequent vibrations during trimming. This results in burrs and uneven edges at the cutting point, greatly affecting subsequent foil rolling. Utility Model Content

DETAILED DESCRIPTION

[0022] The application will be further described below in conjunction with the specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative changes belong to the protection scope of the application.

[0023] As shown in Figure 1 and 2 The technical scheme adopted by the utility model is: a device for preventing aluminum roll 100 from shaking, comprising unwinding mechanism 1, first guide mechanism 2, cutting mechanism 3, stabilizing mechanism 4, edge cutting mechanism 5, second guide mechanism 6 and winding mechanism 7 arranged in sequence.

[0024] The cutting mechanism 3 is used for cutting the aluminum roll 100 in the transverse direction; the stabilizing mechanism 4 has a pair of oppositely arranged guide grooves, the distance between the two guide grooves matches the width of the aluminum roll 100, the two guide grooves are oppositely arranged, and the guide grooves extend along the unwinding direction of the aluminum roll 100; the edge cutting mechanism 5 is further provided with a waste collecting mechanism on one side.

[0025] In work, the aluminum roll 100 is installed on the unwinding mechanism 1 for unwinding, and after unwinding, the aluminum roll 100 passes through the first guide mechanism 2, the cutting mechanism 3, the stabilizing mechanism 4, the edge cutting mechanism 5 and the second guide mechanism 6 in sequence, and finally the edge cut aluminum roll 100 is wound by the winding mechanism 7. The cutting mechanism 3 can cut off the head bending part of the aluminum roll 100 and the part of the aluminum roll 100 with serious friction marks, which is helpful for subsequent threading operation and prevents pollution and damage to the rear mechanism. Between the edge cutting, the aluminum roll 100 needs to pass through the stabilizing mechanism 4, and the guide grooves of the stabilizing mechanism 4 can limit the two sides of the aluminum roll 100, which not only prevents the aluminum roll 100 from shifting horizontally, but also prevents the aluminum roll 100 from shaking up and down with a large amplitude, which is beneficial to the edge cutting operation of the subsequent edge cutting mechanism 5.

[0026] Specifically, as shown in Figure 3 some embodiments, the cutting mechanism 3 includes an upper cutting knife 31 and a lower cutting knife 32 arranged oppositely, the upper cutting knife 31 is installed on an upper knife holder 33, and the lower cutting knife 32 is installed on a lower knife holder 34. The upper knife holder 33 can move away from or close to the lower knife holder 34 under the driving of a power mechanism. The power mechanism can be a lifting cylinder, which drives the upper knife holder 33 to move towards the lower knife holder 34, and in turn drives the upper cutting knife 31 to cooperate with the lower cutting knife 32 to cut the aluminum roll 100.

[0027] As shown in Figure 6 and 7 some embodiments, the stabilizing mechanism 4 includes a chain and a sprocket 71 arranged at both ends of the chain. A plurality of stabilizing blocks 72 are arranged on the chain, and grooves 721 are arranged on the outer sides of the stabilizing blocks 72. The grooves 721 on the plurality of stabilizing blocks 72 form the guide groove. Specifically, one of the sprockets 71 is provided with a motor 73. The chain is arranged on both sides of the aluminum roll 100, the aluminum roll 100 is inserted into the guide groove, and in turn the up-and-down shaking and lateral deviation of the aluminum roll 100 are limited. The stabilizing blocks 72 can move with the movement of the chain, so they do not limit the forward movement of the aluminum roll 100. A power mechanism motor 73 can be arranged on one of the sprockets 71 to make the chain rotate actively, reducing the resistance of the forward movement of the aluminum roll 100.

[0028] As shown in Figure 4 some embodiments, the edge cutting mechanism 5 includes an upper edge cutting knife 51 and a lower edge cutting knife 52 arranged oppositely. The upper edge cutting knife 51 is fixedly connected with an upper rubber roller 53 on one side, and the lower edge cutting knife 52 is fixedly connected with a lower rubber roller 54 on one side. The distance between the upper rubber roller 53 and the lower rubber roller 54 matches the thickness of the aluminum roll 100. The edge cutting mechanism 5 is arranged on both sides of the aluminum roll 100, and the edge cutting operation is performed on both sides of the aluminum roll 100. At the same time that the upper edge cutting knife 51 and the lower edge cutting knife 52 cut the edges of the aluminum roll 100, the upper rubber roller 53 and the lower rubber roller 54 can clamp the inner side of the aluminum roll 100, i.e. the part of the aluminum roll 100 that has not been cut still maintains the original height and will not suddenly drop due to the loss of support caused by the edge being cut off, further improving the stability of the edge cutting.
