Problems solved by technology

[0003] In the existing technology, due to the huge output of laminations, the consumption of Mylar film has increased sharply and the cost is high. At the same time, the replacement of Mylar film and the installation of related equipment for unwinding and winding of Mylar film will undoubtedly increase labor costs, and at the same time make The overall equipment is more complicated and redundant, which increases the overall occupied space and increases the time for machine replacement and downtime. In addition, the Mylar film itself is used as a consumable, and the cost is also high.

Abstract

The invention provides a thermal compounding device, and relates to the technical field of lithium battery manufacturing. The thermal compounding device comprises a supporting wall frame, a hot pressing belt assembly, a hot pressing roller assembly and a heating driving roller passing assembly, the hot pressing belt assembly and the hot pressing roller assembly are oppositely arranged on the supporting wall frame in the vertical direction, a pressing channel for a unit battery cell to pass through is formed between the hot pressing belt assembly and the hot pressing roller assembly, the hot pressing belt assembly and the hot pressing roller assembly are respectively pressed on the upper side and the lower side of the unit battery cell, and the heating driving roller passing assembly is arranged on the discharging side of the pressing channel and is used for thermally compounding the unit battery cell. A unit battery cell conveying device provided by the invention can prevent a mylar film from being used, and can ensure that a pole piece is stable and does not move in the conveying process, extra mylar film winding and unwinding equipment is not needed, and the overall occupied space and the operation cost are reduced.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a thermal compound device. Background technique [0002] At present, in the thermal lamination stage, the unit cell formed by the pole piece and the separator is usually heated in a thermal lamination oven and then thermally laminated by the roller assembly. sheet, to prevent the movement of the pole piece, that is, lay Mylar film on the upper and lower sides of the unit cell, and remove the Mylar film after the thermal compounding is completed. Due to the existence of the Mylar film, the unit cell can be transported Keep it fixed and avoid movement. [0003] In the existing technology, due to the huge output of laminations, the consumption of Mylar film has increased sharply and the cost is high. At the same time, the replacement of Mylar film and the installation of related equipment for unwinding and winding of Mylar film will undoubtedly increase labor ...
