Problems solved by technology

[0003] However, other processes need to be carried out in the subsequent part of the battery case, and the insulating layer cannot be coated. In the prior art, the blue film is used to cover the above-mentioned areas that need to be covered , this method will not only use a large amount of blue film, which will increase the production cost, but also cause environmental pollution due to the one-time use of blue film, and lead to complex processes and low production efficiency

Abstract

The invention relates to the technical field of spraying tools, in particular to a spraying auxiliary device. The spraying auxiliary device comprises a base, a positioning piece and a clamping and protection assembly; the positioning piece is arranged on the base and is used for positioning the inner side of a battery shell; the clamping and protection assembly comprises a clamping unit and a protection unit; the clamping unit is connected to the positioning piece, and the clamping unit can clamp the outer side of the battery shell; the protection unit is arranged on the inner side of the clamping unit, and the protection unit can be in pressing connection to and cover the outer side of the end part, close to the base, of the battery shell when the clamping unit is in a clamping state; andthe protection unit is connected with a power supply and used for generating a charge induction area in the covered area of the battery shell. The spraying auxiliary device is provided with the clamping and protection assembly, and after the protection unit is electrified, an electrified area with the same polarity as electric charge carried by spraying powder is generated, so that no powder is adhered to the electrified area, the battery shell is prevented from being polluted by the powder, and the spraying process is optimized.

Description

technical field [0001] The present application relates to the technical field of processing tooling for energy storage devices, in particular to an auxiliary spraying device. Background technique [0002] With the development of new energy technologies, secondary batteries are more and more widely used. A secondary battery includes a battery case and an electrode assembly and an electrolyte housed in the battery case. Insulating the surface of the battery case is an important process to avoid insulation failure between secondary batteries. [0003] However, other processes need to be carried out in the subsequent part of the battery case, and the insulating layer cannot be coated. In the prior art, the blue film is used to cover the above-mentioned areas that need to be covered. This method will not only use a large amount of blue film, but also increase the production cost. Improve, and also can make disposable blue film cause environmental pollution, and cause complex wo...
