Device becomes lug in the polarity extension that is cut on one side of pole piece.
Since positive/negative plate is wound simultaneously, is implemented to calculate the position for correcting cutting according to reeling condition, determine that winding is each
The lug relative position of layer ensures the lug position that the centre-to-centre spacing of positive and negative lug and battery core require after shaping.
Since laser cutting is continuously cut in constant-speed operation, cutting speed and laser output power have best match
Relationship, with the speed of winding process can not real-time synchronization, storing buffer unit is added in this example between lug is cut and is wound,
It has blocked in winding process, the influence that pole piece pan feeding waits for, winding lifting speed, winder station indexing uniform velocity change.Simultaneously
Winding process can by detect laser cutting lug position and often economize on electricity core Winding Layer piece long denotation, complete winding,
Cut-out, molding, finished product mark, offline process.
In addition, in laser cutting process, by carrying out length accurate measurement and edge, accurately correction is to ensure follow-up volume
Around the degree of registration of lug.
Furthermore in winding process, pass through tension detection, the control of setting, the functional blocks such as traction, the long, correction of meter so that
Complete machine even running ensures the stability of tension and speed, to can guarantee the performance of molding battery core.
