Winding device

A winding device, comprising:

• a first unwinding equipment, a second unwinding equipment, a third unwinding equipment and a fourth unwinding equipment, respectively configured for outputting a first diaphragm, a cathode pole piece, a second diaphragm and an anode pole piece;
• a merging equipment, arranged downstream of the first unwinding equipment, the second unwinding equipment, the third unwinding equipment and the fourth unwinding equipment, and configured for merging the first diaphragm, the cathode pole piece, the second diaphragm, and the anode pole piece as each passes through the merging equipment, or configured for merging the first diaphragm, the second diaphragm and the anode pole piece as each passes through the merging equipment;
• a pole-piece-inserting equipment, arranged between the merging equipment and the second unwinding equipment, configured for cutting off the cathode pole piece upon passing through the pole-piece-inserting equipment, and further configured for transporting a starting end of the cathode pole piece downstream to the merging equipment;
• a winding equipment, comprising a turret and at least two winding needles which comprise a first winding needle and a second winding needle mounted on the turret;
• the turret being rotatably provided so as to drive each of the at least two winding needles to pass by a first station and a second station sequentially, and the first station being located downstream of the merging equipment;
• a guiding roller, arranged between the first station and the second station;
• when the first winding needle at the first station rotates to the second station along with the turret, the second winding needle rotates to the first station, and the first diaphragm, the second diaphragm and the anode pole piece, which are located between the first station;
• and the second station, wind through the guiding roller;
• the guiding roller configured for guiding the first diaphragm, the second diaphragm, and the anode pole piece to pass by the first station so the first diaphragm, the second diaphragm, and the anode pole piece are positioned to be held by one of the at least two winding needles at the first station;
• and
• a cutter equipment, arranged between the first station and the second station, and configured for cutting off the first diaphragm, the second diaphragm, and the anode pole piece in one time as they pass through the cutter equipment after winding of a trailing end of the cathode pole piece onto the winding needle at the first station,
• wherein the winding device further comprises a pole-piece-processing equipment arranged between the fourth unwinding equipment and the merging equipment;
• wherein the pole-piece-processing equipment comprises a first holding-transporting assembly, a cutter assembly, a gluing assembly, and a second holding-transporting assembly disposed sequentially from upstream to downstream;
• both the first holding-transporting assembly and the second holding-transporting assembly are configured for holding the anode pole piece as it passes through the first holding-transporting assembly and the second holding transporting assembly, the cutter assembly being configured for cutting off the anode pole piece as it passes through the cutter assembly forming an upstream cut-off end and a downstream cut-off end of the anode pole piece;
• and
• the first holding-transporting assembly and the second holding-transporting assembly are adapted to move downstream at the same time to drive the upstream cut-off end and the downstream cut-off end respectively to move from the cutting assembly to the gluing assembly while separating the upstream cut-off end and the downstream cut-off end from each other, and the gluing assembly is configured for bonding the upstream cut-off end to the downstream cut-off end with a tape.
