Description

Technical Field

[0001] This application belongs to the field of battery processing technology, and specifically relates to a structure for riveting the positive electrode of a steel-cased battery. Background Technology

[0002] Compared to automotive power batteries or energy storage batteries, batteries for consumer electronics such as smart wearables have very small positive electrode diameters (around 1mm), requiring high riveting precision. This makes riveting the positive electrode electrode particularly difficult, and also presents the problem of the gasket warping upwards around its edges during riveting. Currently, the industry standard involves manually fixing the product to a fixture and then placing it on a riveting machine for riveting. During riveting, the pressure is concentrated in the middle, causing the gasket to warp upwards due to the pressure difference, posing a risk of inadequate sealing and electrolyte leakage. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings in the prior art, this application provides a steel-cased battery positive electrode riveting structure to solve some of the above problems. The structure is compact and solves the problem of the metal gasket warping upward due to pressure difference during riveting, thereby reducing the risk of electrolyte leakage due to unreliable sealing caused by the warping of the metal gasket.

[0004] The technical means adopted in this application to solve the above-mentioned technical problems are:

[0026] like Figures 1-2 As shown, this embodiment provides a structure for riveting the positive electrode of a steel-cased battery, including a mounting base 1, a first telescopic mechanism 2, a riveting component 3, a second telescopic mechanism 4, and a riveting head 5; the first telescopic mechanism 2 is mounted on the mounting base 1; the riveting component 3 is connected to the first telescopic mechanism 2 and is used to press the positive electrode post of the battery; the second telescopic mechanism 4 is mounted on the mounting base 1; the riveting head 5 is connected to the second telescopic mechanism 4 and is used to press the metal gasket of the battery.

[0027] In some preferred embodiments of this utility model, both the first telescopic mechanism 2 and the second telescopic mechanism 4 include a servo motor 6 and a cylinder 7, with the servo motor 6 connected to the cylinder 7. Thus, the use of the servo motor 6 for control improves the overall accuracy.

The movable plate 8 is mounted on the first telescopic mechanism 2, and the guide shaft 9 is slidably mounted on the mounting base 1 and connected to the movable plate 8.

Thus, the top-connecting bolt 11 can abut against the press-fit mounting plate. By adjusting the positions of the two top-connecting bolts 11, the position of the press-fit mounting plate is adjusted, ultimately achieving the adjustment of the press-fitting position of the press-fitting component 3 and the press-fitting head 5.

This solves the problem of the metal gasket warping upward due to pressure difference during riveting, and reduces the risk of electrolyte leakage caused by the warping of the metal gasket.
