Description

Technical Field

[0001] The utility model belongs to the technical field of battery production and manufacturing, and particularly relates to a plate grabbing mechanism. Background Technique

[0002] In the production of battery plates, it is inevitable to grab the battery plates. For example, during the sampling inspection process of battery plates, it is necessary to grab the cut block-shaped plates from the conveyor belt and place them on the weighing platform for inspection. After the inspection is completed, the block-shaped plates are grabbed and placed back on the conveyor belt again; or during the battery assembly production process, the positive plates and negative plates need to be encapsulated with separators and neatly stacked into a group according to the specified quantity and order, that is, the so-called encapsulation and matching. At this time, it is also necessary to grab the plates from one position and place them at another position. Based on this, it is inevitable to use a mechanical gripper to grab the plates.

[0003] For example, CN221140198U discloses a battery plate sampling inspection grabbing mechanism. The grabbing mechanism includes a mounting seat for installing a vacuum suction cup; at least two movable rods are connected to the top of the mounting seat, and an activity ring is connected to the upper surface of the mounting seat on the periphery of the movable rod through spring A; a threaded section is provided at the end of the movable rod; it also includes a mounting plate installed at the end of the robotic arm. The movable rod movably penetrates through the mounting plate, and a nut is provided on the threaded section and abuts against the upper surface of the mounting plate, and the activity ring abuts against the lower surface of the mounting plate; although this grabbing mechanism can grab the plates, for plates of different sizes, it cannot provide a good grabbing effect.
