Abstract
The utility model discloses a winding pin for adjustable static prevention square type lithium battery winder, which comprises a winding pin fixing block, a pair of winding pin and axial sleeve. A long circular hole and a square hole are arranged at the handle section of the winding pin and are connected with the winding pin fixing block via a dowel and a locating pin; the head of the winding pin inserts into the inner hole of the axial sleeve. Because the utility model adopts the dual fixing pin shaft hinge structure and locates with a regulating screw, the width of the winding pin can be adjusted within certain scope. Besides, along with the changes in the width of the lithium battery, the width of winding pin can be adjusted to realize the winding of a battery core according to different size of battery, thus resolving the problem in prior art that the winding pin must be replaced in changing the size of battery. Meanwhile, a polyfluortetraethylene coating is plated on the surface of the winding pin, which greatly reduces the fiction force of an electrode core and the surface of winding pin and eliminates the friction static in drawing out the winding pin. Therefore, the winded battery core is free from the problem of drawout electrode core and the percent of pass of product and the utilization rate of equipment are remarkably enhanced.
Description
Technical field
The utility model belongs to lithium ion battery manufacturing equipment technical field, relates to a kind of production equipment of lithium ion battery cell winding process, is specifically related to a kind of adjustable antistatic square lithium battery winder volume pin.
Background technology
The volume pin width of square lithium battery winder is fixed in the prior art, variation along with different size lithium battery width, the volume pin that will exchange different size as requested for during up-coiler coiling battery battery core is reeled, so just make that enterprise must be according to the kind of battery and the volume pin of model outfit different size, whenever change a kind, must Installation and Debugging once, bother very much, make troubles to work, and after the battery battery core coiling is finished, extract out when rolling up pin, because the frictional force of volume pin and electric core and the static of generation tend to the phenomenon that causes Battery Pole Core to loose core, the qualification rate of product reduces greatly.
Summary of the invention
The purpose of this utility model provides a kind of adjustable antistatic square lithium battery winder volume pin, it is simple in structure, easy to install, be suitable for various lithium ion battery cell winder winding process production equipments, it has solved prior art and has changed the inconvenience that the battery specification is brought, and reduced the frictional force when extracting the volume pin and the generation of static, guaranteed the winding quality of Battery Pole Core.
The technical scheme that the utility model adopted is, a kind of adjustable antistatic square lithium battery winder volume pin, comprise volume pin fixed block, a pair of volume pin and axle sleeve, a pair of volume needle handle portion inserts in the hole of volume pin fixed block, be connected with volume pin fixed block with alignment pin by pin, the head of volume pin is inserted in the endoporus of axle sleeve.
Its feature of the utility model also is,
The shank of described volume pin is provided with a slotted hole and a square hole.
The endoporus of described axle sleeve is an I shape hole.
The surface of described volume pin is coated with polytetrafluorethylecoatings coatings.
The adjustable antistatic square of the utility model lithium battery winder volume pin, adopt two fixed pin shaft hinge arrangements, the volume faller gill is provided with slotted hole and can laterally moves, locate by set screw, make volume pin width-adjustable within the specific limits,, need only different size according to the battery specification along with the variation of different size lithium battery width, adjust volume pin width and just can realize the coiling of battery battery core, solved the more inconvenience that brought of change of lap pin of prior art replacing battery specification.Be coated with polytetrafluorethylecoatings coatings on the surface of volume pin simultaneously, electrode cores reduces greatly with the frictional force of volume wire surface, eliminated by extracting the frictional static that the volume pin produces out, the winding battery battery core no longer produces the Battery Pole Core phenomenon of loosing core, and product percent of pass and capacity utilization significantly improve.
