Description
Technical Field
The invention relates to the technical field of button battery welding, in particular to a method for quickly welding a lug and a shell of a button battery.
Background
Button cell is a kind of high-energy cell which is commonly used at present, and has become the main power source of various portable electronic products because of its advantages of high working voltage, large energy density, long cycle life, no memory effect, etc. In button cell production process, need weld the utmost point ear of book core to the casing through ultrasonic bonding, however, present ultrasonic bonding device's bonding tool is most for bump formula or planar mode, and bump formula bonding tool causes the damage to utmost point ear easily when the welding, leads to the battery quality not good, and when welding utmost point ear and battery case through planar bonding tool, utmost point ear and battery case contact are inseparable, lead to welding badly, and moreover, its welding speed of bump formula and planar bonding tool is all slower, leads to work efficiency low.
Disclosure of Invention
In view of the above, the present invention is directed to the defects in the prior art, and the main object of the present invention is to provide a method for rapidly welding a tab and a case of a button cell, which can improve the welding speed and the working efficiency.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for rapidly welding a lug and a shell of a button battery comprises the following steps:
s1, fixing a shell and a winding core to be welded on a welding platform through a welding jig;
s2, fixing the pole lug on the winding core above the opening of the shell or in the shell;
and S3, welding the lug in the shell by adopting an ultrasonic welding head with a frosted welding surface.
As an optimal scheme, a shell positioning groove and a winding core positioning groove which respectively correspond to the shell and the winding core are arranged on the welding jig.
As a preferred scheme, an air suction hole for fixing the lug is formed between the shell positioning groove and the winding core positioning groove.
Preferably, the roughness of the frosted welding surface is 0.05-0.8 μm.
Preferably, during welding, the ground welding surface of the ultrasonic welding head presses the tab against the bottom surface of the housing for welding.
Compared with the prior art, the invention has obvious advantages and beneficial effects, and concretely, according to the technical scheme, the ultrasonic welding head with the frosted welding surface is mainly adopted to weld the lug in the shell, the welding surface can not damage the lug, the lug can be ensured to be in close contact with the battery shell, the welding quality is ensured, and compared with the traditional welding head, the welding speed is higher, and the working efficiency can be improved.
To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is an enlarged view at a in fig. 1.
The attached drawings indicate the following:
1. welding jig 2 and frosted welding surface
3. Ultrasonic welding head 4 and shell positioning groove
5. A winding core positioning groove 6 and an air suction hole.
Detailed Description
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the positions or elements referred to must have specific orientations, be constructed and operated in specific orientations, and thus, are not to be construed as limiting the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.
The invention provides a method for quickly welding a lug and a shell of a button battery, which comprises the following steps of:
s1, fixing a shell and a winding core to be welded on a welding platform through a welding jig 1;
s2, fixing the pole lug on the winding core above the opening of the shell or in the shell;
and S3, welding the lug in the shell by adopting an ultrasonic welding head 3 with a frosted welding surface 2.
In this embodiment, the welding jig 1 is provided with a casing positioning groove 4 and a core positioning groove 5 corresponding to the casing and the core, respectively, an air suction hole 6 for fixing the tab is provided between the casing positioning groove 4 and the core positioning groove 5, the ultrasonic welding head 3 has four annular frosted welding surfaces 2 distributed equidistantly, and the roughness of the frosted welding surfaces 2 is 0.05-0.8 μm. Before the welding, put casing constant head tank 4 and roll up the core constant head tank 5 respectively with rolling up the core earlier to let suction hole 6 hold utmost point ear fixedly, when the welding, the dull polish welding face 2 of ultrasonic bonding tool 3 supports utmost point ear and presses and weld in the bottom surface of casing.
In summary, the invention mainly uses the ultrasonic welding head with the frosted welding surface to weld the tab in the shell, the welding surface can not damage the tab, and the tab can be ensured to be tightly contacted with the battery shell, thereby ensuring the welding quality, and compared with the traditional welding head, the welding speed is faster, and the working efficiency can be improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
