Problems solved by technology
[0005] The disadvantages of the above two lithium battery cell stacking technologies are: each time the stacking is performed (that is, when the electrode sheet is delivered to the stacking table), only one electrode sheet can be transported at a time, and the transport efficiency is low, which leads to the overall failure of the stacker. work efficiency is not high

The present invention discloses a composite laminating system. The system comprises a composite plate conveying device, a plurality of electrode plate conveying devices, a thermal composite device anda post-treatment device. The composite plate conveying device is provided with a conveyor belt; the conveying direction of the conveyor belt is the working direction of the laminating system; and electrode plates and separators are subjected to composite lamination during the conveying process of the conveyor belt. The electrode plate conveying devices are used for conveying and transferring positive electrode plates and negative electrode plates and are respectively arranged on the left and right sides of the composite plate conveying device according to the positive and negative electrodesof the conveyed electrode plates. The thermal composite device and the post-treatment device are sequentially arranged behind the end of the composite plate conveying device. The composite processingoperation of conveying and laminating the electrode plates is performed based on multi-device waiting and / or synchronization; the system has the advantages of high lamination efficiency and good applicability of the device; and the upper and lower protective films are used as the protective films for laminating based on the technical characteristics of a preset underlying protective film and a preset top protective film so that the potential damage to the electrode plates is reduced during the thermal compounding process.
Description
technical field [0001] The invention relates to lithium battery automatic processing equipment, in particular to a composite lamination system and a composite lamination method. Background technique [0002] At present, the existing lithium battery lamination technology is mainly divided into Z-shaped lamination and pouch lamination. [0003] Z-shaped lamination is to use the diaphragm assembly to pull out the rolled diaphragm, and fold the diaphragm into a Z-shape through the reciprocating motion of the lamination table or the diaphragm assembly itself. Alternately placed between the folded separators, the positive and negative electrode sheets are separated by the separator. The above process is repeated cyclically until a lithium battery cell with a certain thickness is formed. [0004] The bag-making lamination is to align the upper and lower surfaces of the negative electrode sheet with the separator, heat press around it to make a negative electrode sheet bag, and th...
