The invention discloses a soft pack lithium battery pole lug bending device. A base is included. A first air cylinder is utilized for transmission connection of an upper jacking bearing cushion block.The base is connected with a supporting frame. One side of the supporting frame is in sliding connection with a bending lower tool installing base. The bending lower tool installing base is providedwith a rotor bearing and a bending lower tool. The rotor bearing and the upper jacking bearing cushion block are arranged in a rolling fit manner. A second air cylinder is arranged on the supporting frame and is in transmission connection with a bending upper tool. A third air cylinder is arranged in the supporting frame. One end of the third air cylinder is connected with a bending jacking block.The bending jacking block is arranged on one sides of the bending upper tool and the bending lower tool. The first air cylinder is used for driving the upper jacking bearing cushion block to move sothat the bending lower tool can be driven to move, the second air cylinder drives the bending upper tool to move to press a pole lug, a pole lug pressing buffering block and the bending lower tool arematched to press the pole lug, pole lug bending is assisted, the third air cylinder drives the bending jacking block to advance to conduct bending treatment, and the bending efficiency is improved inthe whole process.
Description
technical field [0001] The invention relates to the technical field of lithium battery tab bending, in particular to a soft package lithium battery tab bending device. Background technique [0002] The mobile phone battery, bluetooth battery, notebook battery, etc. we use in our life all need to use tabs. The battery is divided into positive and negative poles. The tabs are the metal conductors that lead the positive and negative poles out of the battery. Generally speaking, the ears of the positive and negative poles of the battery are the contact points when charging and discharging. This contact point is not The copper sheet we see on the outside of the battery is a connection inside the battery. [0003] Soft-pack ternary power lithium-ion battery, the tab is an important part of the lithium battery, in order to match different products, the tab needs to go through the bending process, but the current bending efficiency is low, and the R angle of the bent tab is large, ...
