Bag making and lamination all-in-one machine

Abstract

The invention discloses a bag making and lamination all-in-one machine, which comprises a first bag making pole piece loading device and a second pole piece loading device, wherein the front side of the first bag making pole piece loading device is provided with a first bag making pole piece transportation mechanical arm; the left side of the first bag making pole piece transportation mechanical arm is provided with a first bag making pole piece positioning device; and the front side of the first bag making pole piece transportation mechanical arm is provided with a hot-pressing bag making device. By use of the bag making and lamination all-in-one machine, a bag making system and a lamination system are combined to omit the steps of storage and transportation after bag making is carried out, so that the relative position deviation of the pole piece in bag making in the processes of storage and transportation is lowered, and the quality of a cell is guaranteed. A hot-pressing mobile bagmaking mode is adopted to carry out bag making, i.e., in a process that a mobile station moves backwards to pull a diaphragm, the hot-pressing end socket of the hot-pressing bag making device is downwards pressed to make bags, the hot-pressing end socket rises to reset while the mobile station returns back, bag making auxiliary time is shortened, and bag making efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a bag-making and stacking integrated machine. Background technique [0002] The existing lithium battery cell manufacturing process is generally divided into two types: 1. The coiled diaphragm alternately winds the positive and negative electrodes to form a cell; 2. The coiled diaphragm and the positive and negative electrodes alternately form "Z" shape, laminated into batteries or diaphragms to wrap the positive electrode around to make a bag, and then alternately laminated with negative electrodes to form a battery, the latter is also called bag-type laminates , while the bag-making and lamination are carried out separately in the current bag-type lamination, and the layout of the device is not reasonable enough. The lamination accuracy is serious, it is easy to cause poor short circuit of the battery cell, and the processing efficiency is low. Contents of...
