Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a washing and drying equipment for EV rectangular battery,

The present invention relates to a washing and drying apparatus for washing and drying an electrolyte solution which fouls a surface during a manufacturing process of a battery. More particularly, the present invention relates to a washing and drying apparatus for washing and drying a battery, And more particularly, to an apparatus and method for cleaning and drying a prismatic battery (EV) capable of rapidly processing a battery by automation.

Generally, the battery is inserted into a plurality of compartments that are partitioned by the inner diaphragm of the battery case. The electrode plate has alternately formed through holes on both upper sides thereof. An upper portion of the electrode plate assembly is provided with a connection terminal Strpa for electrically connecting each of the electrode plate assemblies received in the battery case.

The connection terminal has a horizontal surface fixed to the electrode plate assembly and a vertical surface vertically installed on one side of the horizontal surface. The electrode plate assembly is disposed close to the vertical surface of the other connection terminal connected to the other electrode plate assembly accommodated in the adjacent compartment and the through hole of the diaphragm when the electrode plate is received in the compartment.

That is, the different connection terminals located in the different compartments are positioned so as to be opposed to each other on both sides of the through hole of the diaphragm. At this time, the vertical surfaces of the side connecting terminals facing each other and opposed to the through holes of the diaphragm are welded and bonded through the through holes while pressing the tips of the spot welder from both sides. Accordingly, the connection terminals of the different electrode plate assemblies of the different compartments are electrically connected.

In addition, after the electrode assembly is electrically coupled as described above, after the electrolyte is injected into the battery case, the cover is fixed to the case to complete one battery.

The battery manufactured through such a process is contaminated by impurities remaining in the electrolyte solution on the surface of the case or generated during other manufacturing processes. Therefore, the manufacturer removes residue such as debris through the washing process of the battery.

Meanwhile, the EV battery market is divided into 'square type', 'pouch type' and 'cylindrical type' depending on its shape. Because battery type has a decisive influence on cost structure, body structure, design, and weight, Samsung SDI and LG Chem, which are dominant companies in Korea, are fiercely competing with their main batteries as the industry standard.

Conventional battery water washing apparatuses perform a drying process in which water is sprayed from an outer surface of a battery conveyed through a conveyor to remove electrolyte residues remaining in the outer surface and sprayed with heated air through a heater to remove moisture from the outer surface of the battery Respectively.

However, in the conventional battery water washing apparatus, although one or more nozzles for spraying high-pressure water are installed on the outer surface of the battery, the water is simply sprayed without contact with the outer surface of the battery case, There was a problem.

In order to solve such a problem, Japanese Patent Application Laid-Open Nos. 10-1338643 and 10-1302013 disclose a method of manufacturing a battery in which a brush and a nozzle are provided to remove residue of an electrolyte to directly contact the outer surface of the battery, A battery water washing device and a battery drying device capable of completely removing residual water by applying high-temperature and high-pressure air from both sides of the top and sides of the battery being transported so as to remove residual water after cleaning the battery.

However, the above-described flushing apparatus and drying apparatus have a problem in that washing and drying are performed by spraying water and air to a battery being conveyed by using a conveyor belt, and a portion closely attached to the conveyor belt is not cleaned and dried.

In addition, there is a limitation in performing a complete washing and drying operation due to a lack of a structure for intensively washing or drying a specific part of the battery.
