Composite pole piece conveying device and composite pole piece conveying system

Abstract

The invention provides a composite pole piece conveying device and a composite pole piece conveying system and relates to the technical field of lithium battery manufacturing. The composite pole piececonveying device comprises a first frame body and a second frame body which are oppositely arranged, wherein a first hot-pressing roller assembly is arranged on the first frame body, a second hot-pressing roller assembly is arranged on the second frame body, a pressing channel for a composite pole piece to pass through is formed between the first hot-pressing roller assembly and the second hot-pressing roller assembly, and the first hot-pressing roller assembly and the second hot-pressing roller assembly are used for being pressed on the upper side and the lower side of the composite pole piece respectively. Compared with the prior art, the composite pole piece conveying device provided by the invention has the advantages that the composite pole piece is clamped and conveyed by the hot-pressing roller assembly instead of a mylar film, so that an MYLAR film can be prevented from being used, extra equipment is not needed for compounding, and the overall occupied space and the operationcost are reduced.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a composite pole piece conveying device and a composite pole piece conveying system. Background technique [0002] At present, when the pole piece and the diaphragm are combined in the thermal laminating machine, the MYLAR film is used to clamp and transport the pole piece to protect the pole piece and prevent the pole piece from moving. Due to the large output of laminations, the consumption of MYLAR film is large, which increases the cost of consumables, and the replacement of materials takes up production time. [0003] However, in the prior art, it is difficult to replace the MYLAR film with other methods for thermal lamination due to the inability to find a suitable carrier. At the same time, the use of MYLAR film for compounding will require a lot of additional equipment, which will undoubtedly increase the overall occupied space. At the same time, th...

Due to the large output of laminations, the consumption of MYLAR film is large, which increases the cost of consumables, and at the same time changing materials takes up production time

[0003] However, in the prior art, it is difficult to replace the MYLAR film with other methods for thermal lamination due to the inability to find a suitable carrier.

At the same time, the use of MYLAR film for compounding will require a lot of additional equipment, which will undoubtedly increase the overall occupied space. At the same time, the structure is complex, which increases the time for machine replacement and downtime. In addition, the MYLAR film itself is expensive as a consumable, which increases the operating cost.
