Winding laminating machine and laminating method thereof

Abstract

The embodiment of the invention discloses a winding laminating machine and a laminating method of the winding laminating machine. The winding laminating machine comprises a winding device and a controller, wherein the winding device comprises a clamp for clamping articles to be wound, and a rotating mechanism for driving the clamp to periodically and intermittently rotate a preset angle, so that a diaphragm is further wound outside the articles to be wound; the controller is connected with and controls a diaphragm supply device, a pole piece supply device, a winding device and a laminating device to be mutually matched to laminate and wind; two suits of laminating devices are arranged and symmetrically arranged at two sides of a winding station of the winding device, and a pole piece is respectively laminated to the diaphragm from two sides to form the articles to be wound at the same time. According to the winding laminating machine and the laminating method of the winding laminating machine disclosed by the embodiment of the invention, with the technical means of adopting the laminating devices which are symmetrically arranged at two sides of the winding device and laminate on the diaphragm from two sides at the same time after the winding device drives the diaphragm to wind at the preset angle each time, the technical effect of finishing laminating in the winding process of the diaphragm is achieved, the laminating efficiency is high and the quality is good.

Description

technical field [0001] The invention relates to a field of battery manufacturing equipment, in particular to a winding lamination machine and a lamination method thereof. Background technique [0002] The stacked pole piece group used in lithium batteries is made of multi-layer positive and negative pole pieces, and a separator is arranged between the positive and negative pole pieces. In the early days, manual operation was used for stacking, that is, the positive and negative plates and diaphragms were stacked alternately in the fixture according to the requirements manually, and the adhesive tape was pasted after manual inspection to prevent loosening. This method has the disadvantages of high labor intensity, low efficiency, difficulty in accurate lamination, easily damaged pole pieces, and poor product consistency. [0003] The emergence of automated lamination equipment has increased production efficiency and improved product quality. For example, in an existing auto...

Problems solved by technology

Its reciprocating mechanism is equipped with four sets of suction piece components and diaphragm folding mechanism, which has a large weight and volume, and will generate a lot of inertia in actual operation, making it difficult to reciprocate at high frequency. At the same time, because the diaphragm is not effectively wound, manual It is easy to cause looseness when taking out the pole piece group, which makes the follow-up operation difficult
