Description

Technical Field

[0001] The utility model relates to the technical field of battery cleaning, in particular to a battery tray structure and a tray cleaning device including the same. Background Art

[0002] In order to transport battery cells, it is usually necessary to place the battery cells on a battery tray. During the transfer process of the battery tray, the electrolyte will splash or fall on the battery tray. Therefore, it is necessary to support a tray cleaning device to regularly clean the battery tray contaminated by the electrolyte to prevent cross-contamination of the batteries.

[0003] In the existing battery tray design, the battery cells are usually directly placed on the tray rack, lacking effective isolation measures. When a certain battery cell catches fire, the fire is likely to spread rapidly to other battery cells, resulting in the failure of the entire battery system and even triggering safety accidents.

[0004] To solve the above problems, some battery tray designs have begun to introduce partition structures to separate the battery cells and prevent the spread of fire. However, these partitions are usually simply placed on the tray rack, lacking firm fixing measures; when cleaning the battery tray, especially under extreme conditions such as centrifugal drying, the partitions are easily thrown out of the tray rack, causing damage to the battery tray.

[0005] Therefore, developing a battery tray structure that can not only effectively isolate the battery cells and prevent the spread of fire, but also ensure the firm fixing of the partitions and improve the safety of the battery system has become an urgent problem to be solved in the current field of battery system design and manufacturing.
