Description

A kind of jig and method for end socket Fast-Maintenance

Technical field

The invention belongs to lithium battery manufacturing technology field more particularly to a kind of jig for end socket Fast-Maintenance and Method.

Background technique

Soft package lithium battery has many advantages, such as energy density height, good cycle, does not explode, flexible design, is power battery Following developing direction.Soft package lithium battery is a kind of electricity for being protected battery core by the method for heat-seal using aluminum plastic film Pond needs to carry out degasification encapsulation after chemical conversion.It is encapsulated in degasification, in order to guarantee the smooth and consistency of thickness of seal, and Avoiding electrolyte from remaining at seal causes end socket to corrode, usually need to be in one layer of Teflon of end socket surface mount, Teflon tool There is heat-resistant pressure-resistant, and electrolyte resistance corrodes, surface feature easy to clean can be good at protecting end socket.But this layer of Teflon The problem of (0.2 ~ 0.6MPa) easily occurs breakage and crumples under a large pressure.Once the Teflon pasted is damaged or crumples, seal Over-voltage or under-voltage situation will occur in place, and there are the risks of leakage, and will appear apparent impression on seal also to influence Appearance.Therefore, need to pay close attention to whether Teflon occurs damaged or fold in production process constantly, be such as found to replace immediately. And replace Teflon there are following difficult points: 1) at end socket at a higher temperature (170 ~ 200 DEG C), being unfavorable for personnel's operation；2) It also needs to tear old Teflon under (high-temperature-resistant glove) manually, and pastes new Teflon, and must assure that new replacement iron Fluorine dragon surfacing corrugationless.

In view of this, it is necessory to provide a kind of jig and method for end socket Fast-Maintenance.

Summary of the invention

It is an object of the present invention to: in view of the deficiencies of the prior art, and provide a kind of for end socket Fast-Maintenance Jig, the jig are mainly used for end socket and quickly and easily replace Teflon, and can guarantee the quality of Teflon after replacement.

To achieve the goals above, the invention adopts the following technical scheme:

A kind of jig for end socket Fast-Maintenance, including handle and the main part being connect with the handle, the main part Upper surface and lower end surface be correspondingly arranged it is fluted；The depth of the groove is 2 ~ 20mm；The width of the groove is W_{End socket}+△ W, W_{End socket}For the width of end socket, △ W is 0.3 ~ 3.0mm；The length of the groove is L_{End socket}+ △ L, L_{End socket}For the length of end socket, △ L For 0.3 ~ 5.0mm.

As a kind of improvement of the jig of the present invention for end socket Fast-Maintenance, the side wall of the groove leans outward Tiltedly setting.

As a kind of improvement of the jig of the present invention for end socket Fast-Maintenance, the side wall of the groove leans outward Oblique angle [alpha] is 95 ~ 120 °.

As a kind of improvement of the jig of the present invention for end socket Fast-Maintenance, the side wall of the groove is set as Arc-shaped.

As a kind of improvement of the jig of the present invention for end socket Fast-Maintenance, the bottom of the groove is polished Processing.

As a kind of improvement of the jig of the present invention for end socket Fast-Maintenance, the main part with a thickness of 5 ~ 20mm。

A method of for end socket Fast-Maintenance, comprising the following steps:

1) first upper surface and lower end surface sticking two-faced adhesive tape in main part, then exists the shiny surface of Teflon and sticking double faced adhesive tape Together, the viscose of Teflon faces outwardly；

2) jig is placed between upper cover and lower head, and upper cover and lower head alignment indentation is set, then upper envelope Head and lower head close up to centre, and Teflon is pasted on upper cover and lower head automatically；

3) Teflon of two sides is smoothed to the two sides in upper cover and lower head.

Compared with the prior art, the beneficial effects of the present invention are: Teflon is pasted on jig of the invention, only need Jig is placed between upper cover and lower head, is then merged upper cover and lower head, Teflon will be pasted onto automatically On end socket and lower head, the function to end socket quick-replaceable Teflon (within 1min) is realized, and can guarantee stickup Teflon Flatness.
