Lithium ion battery hot and cold-press formation equipment

Abstract

The invention belongs to the technical field of battery manufacturing equipment and in particular relates to lithium ion battery hot and cold-press formation equipment. The lithium ion battery hot and cold-press formation equipment comprises a stander, a material loading tray, a hot-press formation clamp, a cold-press clamp, a material unloading tray, a manipulator and a formation cabinet, wherein the material loading tray, the hot-press formation clamp, the cold-press clamp, the material unloading tray and the manipulator are arranged on the stander; the formation cabinet is electrically connected with the hot-press formation clamp; the cold-press clamp and the hot-press formation clamp comprise laminated plates; the laminated plates are in contact with a battery, and included angles formed between the contact surfaces of the laminated plates and the horizontal plane are 90+ / -0.5 degrees; the manipulator can catch the battery at a time and move among the material loading tray, the hot-press formation clamp, the cold press clamp and the material unloading tray. The equipment integrates three working procedures, namely formation, hot press and cold press, on the battery, so that the time of all the working procedures is shortened; meanwhile, the formation and hot press working procedures on the battery are integrated into the same hot-press formation clamp, so that the working procedure is simplified, and the unnecessary working procedure time is shortened; furthermore, the usability of the battery cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing equipment, and in particular relates to a lithium-ion battery hot and cold pressing forming equipment. Background technique [0002] In the production process of flexible packaging lithium-ion batteries, formation, hot pressing and cold pressing are three important processes in the battery forming process. Formation is to activate the internal activity of the battery to ensure its good charge and discharge performance and cycle life. The hot and cold pressing process is to ensure that the battery has good performance while maintaining a good appearance. [0003] In the existing flexible packaging lithium-ion battery production equipment, the formation of the battery and the hot and cold pressing process are basically carried out separately, requiring different equipment and fixtures. The working process is: after putting the battery into the formation fixture, use Machine or manual ...

Problems solved by technology

In this way, there are many procedures for the formation of batteries, and the production efficiency is low; each process requires corresponding equipment, which is expensive and occupies a large area; and it is necessary to carry heavy formation fixtures, which takes a long time; traditional formation cabinets pass through their The conductive probe on the battery is connected to the electrode plate on the formation fixture to charge and form the battery. The formation current is small, the formation time is long, and the probe is used for a long time, and its contact reliability is reduced; and the battery formation requires a certain temperature. And after the formation is completed, the formation jig needs to be moved out of the formation cabinet. During the process of transferring the jig to the hot pressing equipment and feeding equipment, the heat of the formation jig has already been lost. When the formation jig is reloaded into the battery and enters the formation cabinet, it needs to be preheated again. cause energy waste
