Description

Technical Field

[0001] The utility model relates to a baking tray, in particular to a baking tray for soft-packaged bare batteries. Background Art

[0002] After winding or stacking, the soft-pack bare cell is encapsulated with an aluminum-plastic film bag. The electrolyte is injected through the reserved opening of the aluminum-plastic film bag on the side. Before injection, the soft-pack bare cell needs to be baked between 80℃ and 120℃ for 24 hours. The purpose is to evaporate the moisture and volatile substances in the cell by heating, while enhancing the stability of the cell structure and reducing the risk of internal self-heating. Because the soft-pack bare cell is relatively light and thin, the baking workload is large. During the process, it is easy to cause the bare cell pole ear to bend, causing assembly difficulties at the next workstation. In order to solve this problem, a special baking tray for soft-pack bare cells is designed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a soft-pack bare cell baking tray which has a simple structure, a long service life, high temperature resistance and can be recycled to achieve the purpose of reducing costs and increasing efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a soft-pack bare battery cell baking tray, including a POM outer frame and a tray stop bar, the POM outer frame cooperates with the tray stop bar through a card slot, the tray stop bar is arranged in the POM outer frame, the bare battery cell is placed in the middle of the tray stop bar, and the single-sided gap between the bare battery cell and the tray stop bar is 0.6mm.

[0005] Preferably, the bare cell tab position and the edge of the aluminum-plastic film adopt an air-avoiding structure.

[0006] The beneficial effects of the utility model include: reasonable structural design, no deformation during high-temperature baking, large loading quantity, easy detachability and easy taking, and effective protection against deformation of bare battery cell tabs leading to difficulty in subsequent assembly.

[0010] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0011] Reference Figure 1-2 This specific embodiment adopts the following technical solution: a soft-pack bare cell baking tray, including a POM outer frame 1 and a tray stop bar 2, the POM outer frame 1 cooperates with the tray stop bar 2 through a card slot 3, the tray stop bar 2 is arranged in the POM outer frame 1, and a bare cell 4 is placed in the middle of the tray stop bar 2, and the single-sided gap between the bare cell 4 and the tray stop bar 2 is 0.6 mm.

[0012] It is worth noting that the position of the bare battery cell tab and the edge of the aluminum-plastic film adopt an air-avoiding structure 5.

[0013] The tray of this specific embodiment is made of POM material with high impact toughness, good rigidity, high impact compressive strength and high temperature resistance through injection molding process. The tray is mainly composed of an outer frame and a tray baffle, and the baffle is also injection molded with POM material with stable physical properties. The card slots set on the POM outer frame are convenient for disassembly, installation and maintenance. The single-sided gap in the middle of the baffle for placing bare cells is 0.6mm, which prevents scratches and shaking from causing damage to the surface of the bare cells; the position of the tabs and the edge of the aluminum-plastic film are treated to avoid air leakage to prevent deformation of the tabs and the aluminum-plastic film during baking;

[0014] The high-temperature baking of this specific embodiment does not cause deformation, has a large loading quantity, is detachable and easy to take, and effectively protects the bare battery cell tabs from deformation, which may cause difficulties in subsequent assembly.

[0015] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
