In order to achieve the above object, the technical solution adopted in the present invention is:
Method for cutting edge: the lug that spacing to be punched is changed be divided into two parts carry out die-cut, i.e. L
n=L+ △
n, wherein L is isometric main spacing, △
nfor the correction length changed, when die-cut, first die-cut constant length L, fixed length is cut, and then the correction length △ of a die-cut variation
n, revise and cut.
Trimming equipment comprises conveyer belt, and fixed length is cut module, revises and cuts the cache module be provided with between module and two modules, and fixed length is cut module and correction and cut in module and be provided with successively correction module, optoelectronic induction module, die-cut module and driver module; Described correction module, mainly consist of photoelectric sensor, calculates accurately the side-play amount of pole piece according to the changing value of light quantity; Described optoelectronic induction module, mainly contain photoelectric sensor and form, and according to the signal of sensing, determines the position that fixed length is cut and revise the length of cutting; Described die-cut module includes blanking units; Described driver module is to consist of upper and lower two stepping motors, and the step-by-step impulse of the signal combination input provided according to the optoelectronic induction module drives pole piece to reach accurately die-cut; Described cache module, be to consist of slide block, guide rail, limit switch, transition roller, plays coupling front and back pole piece actuating speed, and before and after realizing, the independent operating of cutting is cut and revised to fixed length;
When die-cut, pole piece is placed on conveyer belt, after the correction of correction module, the optoelectronic induction module of cutting in module by fixed length is determined the position that fixed length is cut, and under the driving of driver module, pole piece is stopped in die-cut module, the die-cut fixed length L of die-cut module; Fixed length L die-cut good after, pole piece enters to revise through cache module cuts module; Correction is cut the optoelectronic induction module induction lug of module and is determined the length △ that correction is cut
n, under the effect of driver module and die-cut module, die-cut one of die-cut module is revised length △
n.
Blanking units in described die-cut module can be the jet-bedding formula, can be also that other anyly can meet accurately die-cut blanking units.
Advantage of the present invention comprises:
1) multi pole ears change spacing method for cutting edge provided by the invention is divided into different spacing the correction length of a constant length and a variation, has realized that twice die-cut completing becomes the die-cut method of spacing, improved die-cut efficiency from method.
2) multi pole ears provided by the invention becomes spacing trimming equipment, comprises that the gentle storing module of two die-cut modules guarantees that fixed length is cut and revised when cutting and carries out, and has improved die-cut efficiency.
3) multi pole ears provided by the invention becomes the spacing trimming device, two die-cut modules are independently, has improved the flexibility that blanking die changes first watch, and the useful life of having improved die-cut die head.
