Cell roasting grid for manufacturing batteries

Abstract

The invention belongs to the technical field of battery manufacturing, and specifically relates to a cell roasting grid for manufacturing batteries. The cell roasting grid for manufacturing the batteries comprises at least two holding assemblies which are distributed up and down, wherein a support supporting the holding assembly located at the bottom is arranged at the bottom of the holding assembly; and each holding assembly comprises a bottom plate and a top plate which are the same in size and rectangular. According to the cell roasting grid for manufacturing the batteries, each holding assembly is composed of the bottom plate and the top plate, one side is hinged through a hinge assembly, the other side can be locked through a locking assembly, during roasting, one cell is flatly spread (in a single layer) between the bottom plate and the top plate, in this way, a ventilation effect at the two ends of the cell can be ensured while efficient roasting for the cells is realized, poorventilation caused by mutual stacking is avoided, and moreover, the cells which are transversally arranged are better in drying effect and larger in heating area compared with cells which are vertically arranged; and in addition, the cells are located through the bottom plates and the top plates, the equipment is easy to clean, and cleaning dead angles are few, so that the cells are reliable in quality.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, and in particular relates to a battery cell baking bar for manufacturing batteries. Background technique [0002] The battery cell is a very important part of the battery, and the quality of the battery cell has a crucial impact on the quality of the battery. The moisture in the cell will react with the active materials of the positive and negative electrodes, so too much moisture will inevitably destroy its structure and affect the cycle. Therefore, the baking of the cell before liquid injection is an essential process. At present, the battery baking method is as follows: the battery is placed in a blue plastic box, and the battery is baked in the oven. This kind of blue plastic box for baking batteries has a large slot inside, and the battery cells are stacked on top of each other and placed in the box. It is difficult for hot air to circulate between the batteries during the bak...

Problems solved by technology

This kind of blue plastic box for baking batteries has a large slot inside, and the battery cells are stacked on top of each other and placed in the box. It is difficult for hot air to circulate between the batteries during the baking process. , the water is difficult to evaporate, the battery cells are directly adjacent to each other, the hot air flow inside and around the battery cells is small, and the water removal time is very long, so it takes a long time to bake

[0003] Therefore, the invention with the application number CN201621137055.8 discloses a high-leg baking bar for manufacturing batteries. The high-leg baking bar includes side walls around, a wrench connected to the side wall, and The bottom connected to the wall, the supporting feet connected to the bottom, the side wall and the bottom form a groove for placing the battery, and a plurality of grids are arranged in the groove, and a plurality of air circulation is arranged in the front, rear, left, and right sides of the grid. The hole speeds up the heat dissipation of the battery core and shortens the baking time, but before the battery is baked, it is necessary to clean the oven and tray used to remove the dust and foreign matter in the box and the tray to prevent baking dust from entering. Inside the battery cell, however, the above-mentioned baking tray is inconvenient to take and discharge materials, and there are many holes, so there must be disadvantages of dirt and dirt, and it is not easy to clean
