Technical Field
[0001] The utility model provides a diaphragm coating machine for battery production, belonging to the technical field of battery production. Background Art
[0002] A device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery. After discharge, the internal active substances can be regenerated by charging - the electrical energy is stored as chemical energy; when discharge is required, the chemical energy is converted into electrical energy again. This type of battery is called a storage battery, also known as a secondary battery or a lead-acid storage battery.
[0003] Battery separator refers to a layer of separator material between the positive and negative electrodes of the battery. It is a very critical part of the battery and has a direct impact on the safety and cost of the battery. Its main function is to isolate the positive and negative electrodes and prevent the electrons in the battery from passing freely, allowing the ions in the electrolyte to pass freely between the positive and negative electrodes. The coating process is a process based on the study of fluid properties. One or more layers of liquid are coated on a substrate. The substrate is usually a flexible film or backing paper. The coated liquid coating is then dried in an oven or cured to form a film layer with special functions. A separator coating machine is required in the production of batteries.
[0004] The existing membrane coating machine can basically meet the use needs in the battery membrane coating production process, but there are still certain defects: when the membrane coating machine coats the membrane with liquid through the coating roller, too much coating liquid often remains on the membrane after coating by the coating roller, which not only reduces the subsequent drying efficiency of the coating liquid on the membrane, but also makes it easy for dust to float on the membrane after coating, and the excessive liquid remaining on the membrane will fall from both sides intermittently when it moves, causing a waste of resources. Based on this, the utility model provides a membrane coating machine for battery production. Utility Model Content
