Color deviation correcting device recognizes battery pole piece aberration, prevents battery pole piece sideslip;

Battery pole piece wound roll material on the incipient stage of cutting, blowing reel is more, it is necessary to increase the power output of motor To make blowing spool turns.With the reduction of battery pole piece wound roll material on blowing reel, the material on blowing reel gradually mitigates, and is Ensure that at the uniform velocity convey battery pole piece, it is necessary to reduce the power output of motor to attached cutting mechanism.Here adjusted by blowing Speed variator realizes the control to output power of motor.Blowing arrangements for speed regulation can be realized using ultrasonic wave speed regulator.With The reduction of battery pole piece wound roll material on blowing reel, blowing is detected by ultrasonic wave speed regulator by sending and receiving ultrasonic wave The quantity of battery pole piece wound roll material on reel, and then realize the control to output power of motor.

With discharge mechanism same principle, the rotation of rewinding reel is driven by motor, cuts the battery pole piece completed Need to roll again again and be easy to fetch and deposit, be no battery pole piece coiled strip on the incipient stage of cutting, rewinding reel here , it is not necessary to the high-power output of motor.And therewith, battery pole piece coiled strip increases on rewinding reel, and the power output of motor needs Gradually increase.The control to output power of motor is so realized by rewinding arrangements for speed regulation.Specifically, rewinding arrangements for speed regulation can To be realized using ultrasonic wave speed regulator.With the increase of battery pole piece wound roll material on rewinding reel, pass through ultrasonic wave speed regulator The quantity of battery pole piece wound roll material on rewinding reel is detected by sending and receiving ultrasonic wave, and then realizes the output to motor Power is controlled.

In operation, battery pole piece can lead to not smooth transmission to laser cutting device due to unbalance stress.By putting Expect tension-adjusting gear, rewinding tension-adjusting gear regulating cell pole piece tension force, can be with so as to ensure the smooth of battery pole piece Ensure to laser cutting device conveying uniform.

Color deviation correcting device is arranged on blowing platform, for by recognizing color between the lug of battery pole piece and pole plate Difference, prevents discharge mechanism blowing sideslip.

S8:Battery pole piece cutting is completed, and stops laser cutting device operation.

The battery pole piece that so cutting is completed just is wrapped on the rewinding reel of receiving mechanism, is easy to removing for operating personnel Fortune.

The embodiment of each in this specification is described by the way of progressive, and what each embodiment was stressed is and other Between the difference of embodiment, each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments State bright, professional and technical personnel in the field is realized or using the present invention.To a variety of modifications of these embodiments to ability It will be apparent for the professional and technical personnel in domain, generic principles defined herein can not depart from the present invention's In the case of spirit or scope, realize in other embodiments.Therefore, the present invention be not intended to be limited to it is shown in this article these Embodiment, and it is to fit to the most wide scope consistent with features of novelty with principles disclosed herein.
