Description

锂带控温压延装置  Lithium belt temperature control calendering device
技术领域  Technical field
[0001] 本发明涉及压延机领域， 更具体地说， 涉及一种锂带控温压延装置。  [0001] The present invention relates to the field of calenders, and more particularly to a lithium strip temperature controlled calendering apparatus.
背景技术  Background technique
[0002] 在电池生产过程中， 锂离子电池极片的补锂工艺是提高锂离子电池容量的关键 技术。 补锂工艺的关键在于压延与覆膜， 压延工艺就是把具有一定厚度的锂带 压延成锂膜， 并附着在牵引膜上的一种工艺。 目前采用压延装置对锂带进行压 延吋， 由于来料锂带本身的硬度和厚度不均， 会导致压延得到的锂膜的厚度不 一致。  [0002] In the battery production process, the lithium-replenishing process of the lithium ion battery pole piece is a key technology for improving the capacity of the lithium ion battery. The key to the lithium-replenishing process is calendering and laminating. The calendering process is a process in which a lithium strip having a certain thickness is calendered into a lithium film and attached to the traction film. At present, the lithium strip is calendered by a calendering device. Due to the uneven hardness and thickness of the incoming lithium strip itself, the thickness of the lithium film obtained by calendering is not uniform.
[0003] 目前会采用热风和冷风交替对进入压延装置的锂带进行加热和降温， 但是这种 方式不能对温度进行准确控制， 若热风的温度太高， 会导致锂带太软， 压延得 到的锂膜的表面质量和厚度变化较大； 若冷风的温度太低， 会导致锂带的硬度 太高、 易脆。  [0003] At present, hot and cold air are alternately used to heat and cool the lithium strip entering the calendering device, but this method cannot accurately control the temperature. If the temperature of the hot air is too high, the lithium strip is too soft, and the calendering is obtained. The surface quality and thickness of the lithium film vary greatly; if the temperature of the cold air is too low, the hardness of the lithium strip is too high and brittle.
技术问题  technical problem
[0004] 本发明要解决的技术问题在于， 针对现有技术中压延装置压延得到的锂膜厚度 不均的缺陷， 提供一种锂带控温压延装置， 通过精确控制锂带的温度， 使得锂 膜厚度均匀。  [0004] The technical problem to be solved by the present invention is to provide a lithium-belt temperature-controlled calendering device for accurately controlling the temperature of the lithium strip, so as to reduce the temperature of the lithium strip obtained by calendering of the calendering device in the prior art. The film thickness is uniform.

[0030] 在预压延装置 100和压延装置 200之间、 预压延后的锂带 11的行进路线上， 还设 置有距离传感器 302， 该距离传感器 302用于对预压延后的锂带 11的厚度进行感 测， 且与控制装置连接。 该距离传感器 302可以是例如激光距离传感器， 其数量 可以是两个， 分别设置在锂带 11的两侧， 用于对锂带 11两侧的距离进行感测， 从而得到锂带 11的厚度。 [0031] 在控制装置内， 预先存储有设定距离值。 控制装置接收距离传感器 302感测的 距离数据， 将感测的距离数据与设定距离值进行比较； 并根据比较结果控制电 磁辊施压机构， 以控制第一电磁辊 101和第二电磁辊 102对锂带 11的施压力。 也 就是， 当感测的厚度数据与设定厚度值存在偏差吋， 控制装置会改变电磁辊施 压机构的施压力， 进而改变第一电磁辊 101和第二电磁辊 102对锂带 11的施压力 ， 使预压延后的锂带 11的厚度接近设定的厚度值。 [0030] A distance sensor 302 for the thickness of the pre-calendered lithium strip 11 is further disposed on the travel path of the pre-calendered lithium strip 11 between the pre-calendering device 100 and the calendering device 200.

The distance sensor 302 may be, for example, a laser distance sensor, which may be two in number, respectively disposed on both sides of the lithium strip 11, for sensing the distance between the two sides of the lithium strip 11, thereby obtaining the thickness of the lithium strip 11. [0031] In the control device, a set distance value is stored in advance. The control device receives the distance data sensed by the distance sensor 302, compares the sensed distance data with the set distance value, and controls the electromagnetic roller pressing mechanism according to the comparison result to control the first electromagnetic roller 101 and the second electromagnetic roller 102. The pressure applied to the lithium tape 11 is applied. That is, when the sensed thickness data deviates from the set thickness value, the control device changes the application pressure of the electromagnetic roller pressing mechanism, thereby changing the application of the lithium strip 11 by the first electromagnetic roller 101 and the second electromagnetic roller 102. The pressure causes the thickness of the pre-calendered lithium strip 11 to approach a set thickness value.
