Abstract
The utility model relates to the field of production equipment of lithium batteries, in particular to a coiling needle in a round lithium battery coiling machine; a coaxial splitting coiling needle comprises a sheathing needle which comprises a hollow sheathing tube end and a first coiling needle for coiling a battery cell; a core needle comprises a needle handle end of the sheathing tube end and a second coiling needle for coiling the battery cell; the first coiling needle and the second coiling needle are arranged in a matching way. The coiling needle adopts a splitting embedded design and the core needle can be inserted into or plugged from the sheathing needle; when in rotating, the two coiling needles are coiled by active force application and the stress is reasonable; in addition, the coiling needle has simple structure.
Description
Technical field
The utility model relates to lithium battery production equipment field, the volume pin in particularly a kind of circular lithium battery winder.
Background technology
Volume pin in the cell winding device of existing circular lithium battery, varied, its primary structure all is to be made of two halfround bar slices volume pin, and install relatively, barrier film, pole piece insert between two volume pins, reel, one of them volume pin is an application of force volume pin, and it is initiatively reeled; And another volume pin is driven volume pin, and it is passive coiling under the drive of master file pin.
Above-mentioned winding needle construction complexity, and exist stressed reasonable inadequately, the problems such as circular runout is big of volume pin.
Summary of the invention
The purpose of this utility model provides a kind of coaxial split volume pin simple in structure.
For achieving the above object, the utility model provides following technical scheme:
Coaxial split volume pin,
It comprises
Trocar, it comprises the first volume pin of the sleeve end of hollow and the electric core of reeling;
The core pin, it comprises the second volume pin of the needle handle end that inserts in the described trocar and the electric core of reeling, the placement that is harmonious of the described first volume pin and the second volume pin.
Above-mentioned volume pin adopts the split embedded design, and the core pin can insert or extract trocar, and during rotation, two volume pins are positive force and reel, and are stressed reasonable.In addition, this winding needle construction is simple.
Description of drawings
Fig. 1 is the assembly drawing of the coaxial split volume of the utility model pin;
Fig. 2 is the structure chart of trocar;
Fig. 3 is the structure chart of core pin.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Referring to Fig. 1-Fig. 3, coaxial split volume pin comprises trocar 1 and core pin 2.Trocar 1 comprises the first volume pin 12 of the sleeve end 11 of cylindrical hollow and the electric core of reeling.Core pin 2 comprises the second volume pin 22 that inserts the cylindric needle handle ends 21 in the described sleeve end 11 and the electric core of reeling, the placement that is harmonious of the first volume pin 12 and the second volume pin 22.The needle handle end 21 of core pin 2 inserts and extracts sleeve end 11 for convenience, and the length of needle handle end 21 is slightly larger than the length of sleeve end 11.
Above-mentioned coaxial split volume pin is when carrying out electric core winding, and positive and negative plate and barrier film insert between the first volume pin 12 and the second volume pin 22, and after the end of reeling, extract core pin 2 earlier, then extract trocar 1 again, take off the battery sub-prime by manipulator at last.
Certainly, the coaxial split volume of the utility model pin also can have other distortion.In a word, do conspicuous change, and other every change that does not break away from the utility model essence all should be included within the described scope of claim according to the prompting of above-mentioned example.
