High-precision stacking machine

Abstract

The invention discloses a high-precision stacking machine, comprising a frame, a stacking table for stacking battery pole pieces, and a pick-and-place mechanism for clamping the battery pole pieces and placing the same on the stacking table. The pick-and-place mechanism and the stacking table are all disposed on the frame. The stacking table comprises a rack fixed to the frame, a worktable for stacking the battery pole pieces, and a driving device connected to the worktable. The worktable, after receiving the battery pole pieces placed by the pick-and-place mechanism every time, is driven by the driving device to move a preset distance downwards in the height direction of the frame. The worktable downwards moves the preset distance so that the pick-and-place mechanism discharges the battery pole pieces at the same height relative to the frame every time. Thus, the pick-and-place mechanism can achieve an accurate discharging position and ensures accurate stacking between the battery pole pieces. In addition, the stacking efficiency of the high-precision stacking machine is also increased due to the reduced path of the pick-and-place mechanism.

Description

technical field [0001] The invention relates to the field of lamination of batteries, in particular to a high-precision lamination machine. Background technique [0002] With the rapid development of society, due to the disadvantages of light weight, high energy storage density, long service life, low self-discharge and environmental protection, lithium batteries are used in many digital products such as electric bicycles and notebook computers. [0003] As we all know, the manufacturing process of lithium batteries includes the lamination process of battery pole pieces. The lamination process of lithium batteries refers to stacking the battery positive plate and the battery negative plate at intervals to form battery cells. Existing lithium battery cell stacking machines generally include a frame, a stacking platform for stacking battery pole pieces, and a pick-and-place mechanism for clamping battery pole pieces and placing them on the stacking platform; The sheet stage i...

Problems solved by technology

Since the height of the stacking platform is fixed, when the retrieving mechanism takes material from the positioning platform and places it on the laminating platform each time, the next time the retrieving mechanism discharges the cells, the position will be Above the position where the material was discharged last time, that is to say, the retrieving mechanism takes material from the positioning platform and places the battery pole piece on the stacking platform. The movement path is different, which has the following defects: The mechanism needs to discharge the battery pole pieces at different levels every time, so the alignment of the stacked battery pole pieces is not high; The height of the sheet is used to adjust the feeding position each time, thus reducing the working efficiency of the stacker
