Apparatus and method for winding electrode assembly

Abstract

The present invention relates to an apparatus and a method for winding an electrode assembly which forms a lithium ion secondary battery or a capacitor, and more particularly to an apparatus and a method for winding the electrode assembly that is clamped by a clamper thereby preventing disengagement between the electrode assembly and a winding part and causing stable winding so as to improve operation efficiency and productivity. For this purpose, the apparatus for winding the electrode assembly which forms the capacitor and secondary battery is characterized by comprising the following components: a clamp part which is provided with a first clamper and a second clamper that are formed oppositely and is provided with a first elastomer that can cause the first clamper and the second clamper to deviate with a preset distance; the winding part which is provided with a first winding roller formed outside the first clamper and a second winding roller formed outside the second clamper; a clamper driving part which compresses the first elastomer for causing the first clamper and the second clamper to cling with each other and fastens an end of the electrode assembly provided therebetween; and a winding driving part which causes the first winding roller and the second winding roller to outside part with a preset distance through connecting the second elastomer with the first winding roller and the second winding roller.

Description

technical field [0001] The present invention relates to a winding device and winding method for an electrode assembly constituting a lithium-ion secondary battery or a capacitor (capacitor), and more specifically relates to clamping the electrode assembly with a clip to prevent the electrode assembly from being wound during winding. The electrode assembly winding device and winding method can be separated from the winding part to enable it to be wound securely, thereby improving work efficiency and production performance. Background technique [0002] Recently, compact and lightweight electrical and electronic devices such as cellular phones, notebook computers, and camcorders have been widely developed and produced. Such portable electrical appliances and electronic devices have built-in battery packs, so that they can be activated even in places without other power sources. In order to enable the built-in battery pack to drive portable electrical and electronic devices fo...

Problems solved by technology

[0018] However, when such a conventional winding device is in close contact with the outer peripheral surface of the winding portion 400 when the winding portion 400 is driven to perform the winding operation, the electrode assembly 1 is detached from the winding portion 400 and cannot be wound on the winding portion 400.

[0019] In addition, as described above, when the winding unit 400 is driven, the winding unit 400 cannot wind the electrode assembly 1 due to a decrease in the adhesive force, and there is a problem of idling.
