Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and in particular to a graphene pole piece processing device for lithium batteries. Background Art

[0002] Graphene pole pieces need to be dried during processing. The existing patent (Announcement No.: CN214009827U) discloses a graphene pole piece processing device for lithium batteries. The utility model sets a rotating rod, a bracket, and a rack. The rotating rod drives the bracket and the rack to rotate in the drying box, so that the pole pieces located at different positions in the drying box can be fully dried, which speeds up the drying speed. The hanging ring is used to keep the rack in a drooping state, which to a certain extent avoids the pole piece from falling from the rack. However, the hanging ring and the bracket are in a movable fit, and the pole piece is placed in the rack only by gravity. Therefore, during operation, the hanging ring is very likely to slide back and forth on the bracket, and the two ends of the rack may collide with the two sides of the bracket. The above situations may cause the rack to overturn, resulting in overlapping pole pieces or even causing the pole pieces to detach from the rack, which is not conducive to practical use. To this end, we propose a graphene pole piece processing device for lithium batteries. Utility Model Content

[0012] The advantages and beneficial effects of the utility model are as follows: by setting a tray, a vacuum adsorption mechanism, a mounting base and a mesh cover, after the electrode to be dried is placed in the tray, an air pump is used to extract the air at the bottom of the electrode through the air suction pipe and the adsorber, and a negative pressure environment is constructed in the tray, so that the electrode is tightly attached to the bottom of the tray.
