Aluminum-plastic film folding device for soft-package lithium battery

Abstract

The invention discloses an aluminum-plastic film folding device for a soft-package lithium battery, and relates to the field of battery preparation, in particular to lithium ion production equipment or method. The aluminum-plastic film folding device for the soft-package lithium battery is characterized in that a pre-folded plate placement mechanism is arranged at the top part of the aluminum-plastic film folding device; a battery core position adjusting block is arranged at the lower part of the pre-folded plate placement mechanism; a battery core discharge platform is arranged at the side of the battery core position adjusting block; the battery core position adjusting block and the battery core discharge platform are located on the same horizontal plane; a flat pressure head is arranged between the battery core position adjusting block and the battery core discharge platform; the flat pressure head and an outlet of the pre-folded plate placement mechanism are located on the same vertical line; the flat pressure head is connected with a flat pressing cylinder; a pressure gage is arranged on the side surface of the flat pressing cylinder; a control system is arranged in the middle of the aluminum-plastic film folding device and is connected with a pedal switch; and a V-shaped folding mechanism is arranged at the lower part of the control system. According to the aluminum-plastic film folding device for the soft-package lithium battery, the shortages that a soft-package aluminum-plastic film folding machine is narrow in application range, high in price, high in demands on technology and the like are avoided; and the aluminum-plastic film folding device disclosed by the invention is high in practicability, clever in design, high in flexibility and low in price and is applied to the fields of laboratories and the like.

Description

technical field [0001] The invention relates to the field of battery preparation, in particular to lithium ion production equipment or methods. Background technique [0002] Flexible packaging lithium-ion batteries are widely used in digital, communication, electric vehicles and other fields due to their advantages of high energy density, long cycle life and various shapes, and have become the main direction of lithium-ion battery development. During the battery production process, the stamped aluminum-plastic film case needs to be folded, crimped or shaped to remove excess corners, so that the packaged aluminum-plastic film is flat and sealed, and folded, crimped and then folded The corners of the aluminum-plastic film must be packaged to seal the battery. In the prior art, due to the different width and length of the folded aluminum-plastic film and the type of the aluminum-plastic film, the parameters are often adjusted during the folded edge, and it is difficult to ensur...
