Abstract

The invention relates to a battery clamping mechanism, which is characterized in that it includes a first bottom plate, a clamping jaw movement mechanism and a stretching movement mechanism; two second bottom plates capable of relative movement are symmetrically arranged on the first bottom plate The jaw movement mechanism includes two jaw movement mechanism units symmetrically arranged on the two second bottom plates; the jaw movement mechanism unit includes a left jaw and a right jaw for clamping the left and right ends of the electric core; The stretching motion mechanism includes a stretching drive device installed on the first bottom plate, and the power output end of the stretching drive device is connected to two second bottom plates to make the second bottom plates move relative to each other, so that the two jaw movement mechanism units will clamp The tight battery pulls flat. The invention flattens the circular battery core to obtain a flat battery core, avoids the problems of low winding efficiency of the flat battery core and uneven tension in winding the flat battery core in the prior art, and improves the quality of the battery core.

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 automation manufacturing equipment. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has 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, small 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 manufac...
