Abstract

The invention discloses special equipment for diaphragm coating. The equipment comprises a spraying device and a scraping device. An air inlet purification device, a machine head cleaning device, a coating thickness control device and a multi-stage air suspension power device are arranged on the spraying device. The special equipment for diaphragm coating is special equipment for wide-width air suspension double-sided coating. An air suspension device is further designed and improved in coating tension control, slurry mixing and slurry coating process control so as to cope with defects of traditional diaphragm coating equipment on coating compactness and binding force.

Description

technical field [0001] The invention relates to a lithium battery production device, in particular to a special equipment for diaphragm coating. Background technique [0002] With the increase in sales of new energy vehicles, the demand for high-quality separators for power batteries also increases. The common problem of separators in the prior art is that the consistency needs to be improved. Consistency is mainly reflected in irregular defects, thickness, porosity, pore distribution and pore size distribution. The uniaxially stretched domestic PP separator is relatively close to the benchmark product in terms of porosity and pore size distribution; the biaxially stretched PE separator is usually lower in porosity than the benchmark product, and the pore size distribution is not ideal. [0003] Diaphragm coating is not technically difficult, and gravure roll coating, dip coating, narrow coating or spray coating can be used. The gravure roll coating process is a commonly ...
