Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Specific embodiment one of the battery cover plate sealing welding pre-welding cleaning device of the present invention, as figure 1 As shown, it includes a turntable 3 arranged on one side of the conveyor belt 1. The turntable 3 includes a loading station 4, a cleaning station 5, an air-drying station 6 and a blanking station 7. There are four positioning stations on the turntable 3. The slot 20 is used for rough positioning of the battery cell, so that the cover plate does not slip or displace when the battery cell rotates on the turntable 3 . The turntable 3 is provided with four lifting platforms, and the four positioning grooves 20 are respectively arranged on the four lifting platforms of the turntable 3. The lifting platforms are pneumatic jacking mechanisms in the prior art, and will not be repeated here. The turntable 3 will stop briefly...

Abstract

The invention provides a pre-welding cleaning device for battery cover plate sealing welding . The cleaning device comprises a cleaning rotating wheel and a wheel shaft, wherein the wheel shaft is used for fixedly assembling the cleaning rotating wheel and driving the cleaning rotating wheel to rotate or rotationally assemble the cleaning rotating wheel; and the cleaning rotating wheel is fixedlyprovided with a wiping body arranged around the axis of the cleaning rotating wheel, and the pre-welding cleaning device for the battery cover plate sealing welding further comprises a cleaning liquidsupply device used for supplying cleaning liquid to the wiping body. A traditional cleaning method for manually wiping a to-be-welded region of the cover plate is modified, the cleaning liquid is supplied to the wiping body through the supply device, and the wiping body fixed to the cleaning rotating wheel moves relative to the to-be-welded region of the cover plate, so that wiping of the to-be-welded region of the cover plate is realized; and the cover plate is cleaned by adopting the cleaning rotating wheel, so that the labor cost can be saved, and the consistency of the cleaning degree canbe ensured.

Description

technical field [0001] The invention relates to a surface cleaning device, in particular to a cleaning device before welding of a battery cover plate. Background technique [0002] In the production process of metal shell lithium-ion batteries, laser sealing welding is an indispensable process. When metal shell lithium-ion batteries are welded by laser sealing, due to the existence of impurities such as oil and foreign matter in the welding seam, the foreign matter will vaporize during the welding process. Breaking through the molten pool forms an explosion point, which seriously affects the welding quality. [0003] In order to reduce the explosion point phenomenon of the cover plate during the welding process, the battery case and cover plate will be cleaned with chemical methods to clean oil and foreign matter after they are produced. The cover plate generally has a rectangular plate-shaped structure, the longer side of the rectangle is the long side of the cover plate, ...
