Abstract

The invention relates to a battery cell clamping and connecting mechanism. The battery cell clamping and connecting mechanism is characterized by comprising a first bottom plate, a clamping jaw motion mechanism and a stretching motion mechanism, wherein two second bottom plates capable of doing a relative motion are arranged on the first bottom plate in a fore-and-aft symmetry manner; the clamping jaw motion mechanism comprises two clamping jaw motion mechanism units symmetrically arranged on the two second bottom plates; each clamping jaw motion mechanism unit comprises a left clamping jaw and a right clamping jaw that clamp the left and right ends of a battery cell; the stretching motion mechanism comprises a stretching driving apparatus mounted on the first bottom plate; and the power output end of the stretching driving apparatus is connected with the two second bottom plates for enabling the second bottom plates to do the relative motion, so that the two clamping jaw motion mechanism units pull the clamped battery cell to be flat. According to the battery cell clamping and connecting mechanism, the round battery cell is pulled to be flat to obtain a flat battery cell, so that the problems of low winding efficiency of the flat battery cell and non-uniform tension force during winding of the flat battery cell in the prior art are avoided and the battery cell quality is improved.

Description

Technical field [0001] The invention relates to a cell clamping mechanism, in particular to a cell clamping mechanism used in a lithium battery production system, and belongs to the technical field of battery automated manufacturing equipment. Background technique [0002] Lithium-ion batteries are a new generation of green high-energy batteries with excellent performance and have become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, low internal resistance, less self-discharge, and more cycles. Because of the above-mentioned characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, notebook computers, video cameras, and digital cameras. [0003] The shapes of power lithium batteries are mainly square and round. The cells of square batteries are flat. The traditional preparation ...
