Problems solved by technology

However, during the secondary packaging process of the battery in the existing secondary packaging device, since the electrolyte in the aluminum-plastic film is in a vacuum environment, the electrolyte is prone to splash during the vacuuming process, polluting the secondary packaging. The cavity is not conducive to ensuring the quality of the battery, and even pollutes the outer packaging of the battery

Embodiment approach

[0064] As an embodiment, the number m of vacuum holes 22 ≥ the number n of bayonets 3 and at least (m-l) positions of vacuum holes 22 correspond to bayonets 3, wherein, l is the number of empty grooves.

[0065] It can be understood that the corresponding position means that the bayonet 3 can extend into the vacuum hole 22 during the process of puncturing the air bag 106 .

[0066] In order to facilitate secondary packaging of the battery 100, such as Figure 2 to Figure 4 As shown, the secondary packaging device of the pouch battery in this embodiment also includes a packaging mechanism 5, and the packaging mechanism 5 includes an upper sealing head 51, a lower sealing head 52, a second lifting driver (not shown) and a third lifting The driver (not shown), the upper head 51 is disposed in the housing 1 and above the tray 2 . The lower sealing head 52 is disposed in the casing 1 and is located below the upper sealing head 51 , and the lower sealing head 52 runs through the tr...

Abstract

The invention discloses a secondary packaging device of a soft package battery and a secondary packaging method, and belongs to the technical field of battery processing. The secondary packaging device of the soft package battery comprises a shell and a tray, the tray is arranged in the shell and used for supporting the battery, a cavity is formed in the tray, a vacuum hole communicated with the cavity is formed in the top of the tray, and the cavity is communicated with an external vacuumizing device. The secondary packaging method of the soft package battery comprises the following steps: forming a downward directional airflow channel in a secondary packaging chamber; puncturing the air bag; and carrying out secondary packaging on the aluminum plastic film. The electrolyte can be prevented from splashing to pollute the interiors of the battery and the shell, so that the quality of the battery can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to a secondary packaging device and a secondary packaging method for a pouch battery. Background technique [0002] A soft pack battery usually consists of an aluminum-plastic film, a cell wrapped in the aluminum-plastic film, and an electrolyte set in the aluminum-plastic film. In the forming process of the pouch battery, it is necessary to wind / stack the positive electrode sheet, negative electrode sheet and separator to form a battery cell, and then perform a punching operation on the aluminum-plastic film; then put the battery cell into the punched pit of the aluminum-plastic film , and fold the aluminum-plastic film that has been punched in half to cover the battery cell; and in order to prevent water vapor from entering the aluminum-plastic film, it is necessary to heat-seal the aluminum-plastic film with a heated head. Usually, such as figure 1 As shown, the packa...
