Continuous multi-station battery core winding device

Abstract

The invention discloses a continuous multi-station battery core winding device. The device comprises a rotor, wherein a plurality of needle cylinder assemblies are evenly distributed on a rotor in thecircumferential direction of the rotor, any needle cylinder assembly is correspondingly provided with an elastic pressing assembly, any needle cylinder assembly is connected with a rotation driving assembly used for driving the needle cylinder assembly to rotate, each needle cylinder assembly comprises a guide cylinder, two winding needles are installed in each guide cylinder in the length direction of the guide cylinder in a sliding mode, a gap allowing a strip to penetrate through is formed between two winding needles, an outer side face of the rotor is further coaxially sleeved with a cylinder, an outer side face of the cylinder is provided with a plurality of lifting driving assemblies used for driving the winding needles to slide along the guide cylinder, and the lifting driving assemblies are installed on the rotor, the outer side face of the rotor is further provided with a material pressing and cutting assembly used for pressing and cutting off the strip, the material pressingand cutting assembly is installed at a driving end of a reciprocating rotation driving assembly, and the material pressing and cutting assembly reciprocates in the rotating direction of the rotor. The device is advantaged in that the working stability is improved, and productivity is improved.

Description

technical field [0001] The invention relates to the field of lithium battery processing, in particular to a continuous multi-station battery winding device. Background technique [0002] Cell rolling is a basic and important process that is indispensable for the production of most lithium batteries at present. At present, the battery winding machines on the market are basically designed and manufactured with reference to foreign winding machines. There is a common feature in the core making process: the battery core can only be rolled individually (the core winding process: 1. Sending the sheet to roll the battery core, 2. Changing the station to cut the diaphragm and glue the end, 3. Pull the coiling needle to take the material ), the longest step time in the process plus the time for changing stations is the production cycle, and the current high requirements and subdivision of the single step time have reached the bottleneck. In view of the current situation of fierce p...
