摘要
为了减少涂布工艺中涂层干厚度误差,提高动力锂电池极片生产质量,提升生产效率,研制出一种新型宽幅动力锂电池挤压式涂布机。挤压式涂布机结构主要有大理石平台和漂流烘干箱构成,这种设计有效提高设备耐用性和物理精度,并消除了生产过程中的物料损伤。控制系统采用三菱张力控制器LE-40MTB-E和张力传感器LX-015TD构成闭环控制系统,进行恒张力控制;采用卷径计算单元LE-40MD和变频器构成料带恒速控制,以应对在生产过程中的卷径不断变化。经过严格测试证明,系统运行稳定可靠,各种技术参数符合性能指标,其中单面涂布干厚度误差比传统设备降低了30%左右,有效解决了传统涂布工艺中涂层精度不高问题。
In order to reduce the dry thickness error of the coating process,improve the production quality of power lithium battery pole piece,and increase the production efficiency,it describes the development of a new type large-width extrusion coating machine for power lithium battery.The main structure of extruded coating machine consists of marble platform and drifting drying box,which can effectively improve the durability and physical precision of the equipment,and eliminate the material damage in the production process.The control system adopts the Mitsubishi tension controller LE-40MTB-E and the tension sensor LX-015TD to form the closed-loop control system for realizing the constant tension control;The coil diameter calculation LE-40MD and frequency converter are used to form the material belt constant speed control for coping with the continuous change of the coil diameter.By rigid testing,the system is stable and reliable,and various technical parameters meet the performance index.The dry thickness error of single-sided coating is reduced by about 30%,which effectively solves the problem of low coating precision in the traditional coating process.
