Embodiment

Referring to Fig. 1, a kind of full-automatic lithium ion battery pelleter, it comprises successively: automatic discharging device 1, dust exhaust apparatus 2, deviation correcting device 3, encapsulate and a plurality of rollers (sign) that send lug device 13 (see figure 2)s, welding or riveting portion 4, fixed length draw-gear 5, buffering area 6, deviation correcting device 7, pole piece tape sticking device 8, fixed length draw-gear 9, buffering area 10, shearing retracting device 11, wrap-up 12 and electric part (figure does not show) and carrying pole piece to move;

Above-mentioned automatic discharging device 1 is the disk of a coiled strip, and volume has the raw material pole piece; Dust exhaust apparatus 2 is used to clean the pole piece surface; Deviation correcting device 3 and 7 all is in order to guarantee pole piece non-migration when entering next process, thus guarantee welding or riveted joint lug and rubberizing position accurately; Encapsulate and send lug device 13 to be positioned at the welding or the rear portion of riveting portion 4, invisible in figure one, referring to Fig. 2, it comprise successively material volume 131 that lug is housed, material conveying volume guide wheel 132, send glue component 133, encapsulate parts 134, send lug parts 6 and cut lug parts 8, send the lug parts to send fixed length lug cylinder 7 to drive, also have a pressure lug cylinder 5 that lug is pressed in and send on the lug parts 6 by one; The structure of sending glue component 133 is referring to Fig. 3, and it comprises gummed paper material volume 1331, one-way wheel 1333, moulding groove 1335, moulding piece 1334, locating piece 1336 successively, cuts glue cutter 1339 and send glue cylinder 2, drive the cylinder 1338 of cutting glue cutter 1339, gummed paper and lug are pressed on cylinder 1337 on the locating piece 6.
