Description
Technical Field
[0001] The utility model relates to the technical field of battery cell production, in particular to battery cell baking equipment in a lithium battery factory. Background Art
[0002] In the production process of lithium battery factories, baking the battery cells is an indispensable process. The purpose of this process is mainly to discharge the remaining moisture in the battery cells through high temperature and negative pressure. The current industry practice is to place the battery cells inside the oven, and then use electric heating to bake at high temperature, and then send the battery cells to the cooling box to cool to 40℃ for a period of time. Among them, the oven uses electric heating as the heat source, and the cooling box uses 7℃ chilled water as the cold source.
[0003] For example, a patent document with application publication number CN115875946A discloses a battery cell baking device, which includes: a box body, multiple support parts, and multiple heating components, wherein a accommodating cavity is arranged in the box body; multiple support parts are arranged in sequence in the accommodating cavity along a first direction, and at least one battery cell is placed on the support parts; multiple heating components are arranged in sequence in the accommodating cavity along a first direction, and the heating components and the support parts are alternately arranged, and the heating components include coils, and the polarities of the coils of two adjacent heating components in the first direction are opposite, and the heating components are used to bake the battery cells on the support parts adjacent to the heating components in the first direction.
[0004] In the above device, the polarities of the coils of the two adjacent heating components in the first direction are opposite, and the heating components are used to bake the battery cells on the two support parts adjacent to the heating components in the first direction, thereby achieving the baking treatment of the battery cells. However, since the battery cells need to be cooled after baking, the above device can only be used to simply bake the battery cells. If the baked battery cells need to be cooled, an additional cold source needs to be added. Therefore, the performance of this device is relatively simple, and it can only simply bake the battery cells, which is inconvenient to use; at the same time, if a cold source is added on the basis of this device for subsequent cooling treatment, the production cost of the enterprise will be increased, which is not in line with the enterprise's concept of increasing efficiency and reducing emissions.

[0009] As a further solution of the utility model: the part where the protrusion fits and contacts with the side of the cooling box is integrally formed, so that the cooling end of the semiconductor can be acted on the inside of the cooling box through heat exchange of the protrusion.
[0010] As a further solution of the utility model: a plurality of groups of heat-insulating components are filled between the heating box body and the cooling box body, a plurality of protrusions are arranged and evenly distributed, and the plurality of groups of heat-insulating components are arranged in an assembly gap formed between any two adjacent protrusions.
