Beneficial effect is：Compared with prior art, a kind of pole piece coiling device, the technique speed of electric core winding is not only increased
Degree, improves battery production efficiency, and utilize the mode of heat welded compared with the mode of plug with two-sided gluing knot barrier film
Make directly to be connected as a single entity by one or two kinds of material moltens between barrier film and plug, barrier film firmly, is exactly bonded in
On plug, the quality of battery core has been effectively ensured, has improved its qualification rate.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing, wherein：
Fig. 1 is the structural representation of coiler device of the present invention.
Embodiment
As shown in figure 1, a kind of pole piece coiling device, including up- coiler, the up- coiler includes for winding positive electrode sheet, every
The plug 1 of film 7 and negative plate, in addition to mounting bracket 2, drive mechanism 3 and be bonded in barrier film 7 using the mode of heat welded
The weldment on the surface of plug 1, the plug 1 is horizontally disposed, and the weldment is located at the lower section of plug 1, the weldment
Including guide rod 41, heating circle 42 and blanching first 43, the blanching first 43 is fixed on guide rod 41 towards on one end of plug 1,
The heating circle 42 is arranged in mounting bracket 2 and heated for first to blanching 43, and it is logical that the mounting bracket 2 is provided with guiding
Hole, the guide rod 41 are inserted through in guide through hole；The output end of the drive mechanism 3 is provided with post rod mechanism, the push rod
Mechanism includes the spring guide rail 51 that driving guide rod 41 moves up and down and the rotating shaft 52 for driving spring guide rail 51 to swing up and down, described
One end of spring guide rail 51 is fixedly connected in rotating shaft 52, and the described one end of guide rod 41 away from plug 1 is connected to spring guide rail
On 51.Rotating shaft 52 can be driven by motor, can also install knob, and knob is connected by a steel wire with rotating shaft 52, when
When rotating shaft 52 rotates, affect post rod mechanism to move, so that blanching first 43 is crimped on barrier film 7, barrier film 7 is bonded in plug 1
Surface.Preferably, also barrier film 7 can be made to keep certain tension force steadily to move by transition nip rolls 6, it is pressed close to plug 1
