Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is clearly and completely described, to be completely understood by the purpose of the present invention, feature and effect.Obviously; described embodiment is a part of embodiment of the present invention rather than whole embodiment, based on embodiments of the invention; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of protection of the invention.It addition, all connection/annexations related in patent, the most singly refer to that component directly connects, and refer to couple auxiliary according to being embodied as situation by adding or reducing, form more excellent draw bail.Each technical characteristic in the invention, can be with combination of interactions on the premise of the most conflicting conflict, with reference to Fig. 2-Fig. 3.
Referring in particular to Fig. 2-4, a kind of cell polar ear laser automatic cutting equipment, including installing backboard 1, discharging device 2, material collecting device 3, deflector roll 4 and cut assembly 5 are installed on described installation backboard 1, described cut assembly 5 has two groups of laser cutting devices, each group of laser cutting device all includes cut roller 51 and coordinates the laser cutting head 52 of described cut roller 51, and described laser cutting head 52 can be launched laser cut line and the lug raw band being wound on cut roller 51 is cut into preset shape.
In use, lug raw material is placed on discharging device 2, deflector roll 4 is crossed in lug material strip winding, cut roller 51 is post-rolled on material collecting device 3, and wherein material strip is cut by two laser cutting heads 52 during two cut rollers 51 of winding.
Being the incision principle schematic diagram of cut assembly 5 with reference to Fig. 5, Fig. 5, pole piece raw material is the most tightly wound on cutting roller 51 and assisted on roller 8, therefore pole piece will not be shaken in tape transport process, not resulting in laser out of focus, and then reach the effect of stable cutting, cut quality is good.Two cutting rollers 51 are that the effect reaching effectively to cut have employed special differential speed roll design, i.e. running roller is made up of fixed roll and action roller.Pole coating part is on action roller, and lug part is on fixed roll, and fixed roll is machined with groove at cutting zone, and groove shapes is designed according to cut path specially.Cutting zone has special the aspiration of negative pressure mechanism 55, prevents cutting dust and splashes, and vacuum magnitude is controlled by precise vacuum pressure regulator valve.There is special cutting garbage collection mechanism 56 equally, cutting waste material is effectively collected and prevents waste material from affecting next step cutting.
The described i.e. pole piece two ends of bidifly shaven head 51 cutting simultaneously cut out lug simultaneously, although two laser are staggeredly arranged because of spatial relationship, but calculate the requirement that can accurately ensure the pole piece both sides positive and negative 0.2mm of lug degree of registration through control system particular algorithm.
With reference to Fig. 6, Fig. 7, Fig. 6 is the structural representation before pole piece cutting, and Fig. 7 is the schematic shapes after pole piece cutting.
In Fig. 6, in pole piece, a-quadrant is pole coating district, and B region is lug district to be processed；In Fig. 7, C is the lug processed by lug district to be processed, width 0.5-1mm in applying area on lug, and applying area need to be symmetrical about imaginary center line D on the lug of both sides, error control is at positive and negative 0.2mm, more roller was assisted owing to pole piece can be walked around in running, and these are crossed roller and inevitably there is error during processing and assembling, so pole piece can be caused to offset on roller, for ensureing that error control uses two grades of corrections especially in positive and negative 0.2mm this point, offset signal is chased after wire type sensor acquisition by CCD.

Preferably, it is provided with the aspiration of negative pressure mechanism 55 on described cut assembly 5, the cutting produced in laser cutting process bits can be siphoned away by described the aspiration of negative pressure mechanism 55, the quality that cutting bits affect cut can be avoided after being siphoned away by described cutting bits, also can ensure the neat and tidy of production environment, it is to avoid chip pollutes environment and staff is produced injury simultaneously.
Preferably, described cut assembly 5 is provided with the cutting garbage collection mechanism 56 for clearing up pole piece cutting waste material.After lug material strip is cut to lug product, fall down in corresponding garbage collection box at the waste outlet that the remaining waste material of material strip is corresponding on equipment under the round brush effect of cutting garbage collection mechanism 56.
Preferably, described installation backboard 1 being provided with the tension detecting apparatus 6 of pole piece material strip, described tension detecting apparatus 6 can adjust the tightness of lug material strip as required.
With reference to Fig. 8, Fig. 8 is the principle schematic of tension detecting apparatus 6, in conjunction with tension-sensing roller 61, tension detecting apparatus 6 can Real-time Feedback Tensity size, and tension value is fed back to tension control system, tension control system adjusts Tensity size row in real time and becomes closed loop control according to feedback, reaches the control effect of identical tension.Identical tension inferior pole piece operates steadily, and non-jitter also can effectively control the skidding that pole piece rolls in driving, thus accurately controls lug spacing, is favorably improved the effect of pole piece cutting and promotes degree of accuracy.
Preferably, described installation backboard 1 is also equipped with material strip deflection correction mechanism 7, the deviation that described material strip deflection correction mechanism 7 produces during correcting pole piece raw material itself and unreeling.
Being the structural representation of discharging device 2 with reference to Fig. 9, Fig. 9, described discharging device 2 is double-station unwinding device, uses double-station unwinding can reduce the waiting time of reloading, improves production efficiency.Double-station unwinding shares a set of deflection correction sensor 21, it is ensured that unifying datum, effectively reduces the pole piece skew that change of lap brings, and uses pneumatic type to compress tape splicing platform 22 and has advantage convenient to operation, can reduce the tape splicing time.
Preferably, it is provided with between the cut roller 51 of described two groups of laser cutting devices and assisted roller 8, lug material strip is walked around after walking around one of them cut roller 51 and described was assisted roller 8 more reversely around being set on second cut roller 51, and the working region of the laser cut line that described laser cutting head 52 sends is positioned at lug material strip and is posted by the region of cut roller 51 peripheral surface.
Owing to working region when lug material strip is cut is positioned at around the circumferential position being located at cut roller 51, this position abuts against the sidewall of cut roller 51, thus loosening of position will not be produced in laser cutting process, the precision of cutting is higher, the lug product quality cut out is more preferable, and lug product quality does not haves uneven.
Preferably, also including the control device controlling whole equipment operation, described control device includes the various sensors being arranged on equipment and receives sensor signal and send the processor processing signal.Whole equipment realizes automatic operation under the automatically controlling controlling device, and automaticity is high, and work efficiency is high.
It is above the preferably enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art it may also be made that all equivalent variations or replacement on the premise of spirit of the present invention, and deformation or the replacement of these equivalents are all contained in the application claim limited range.
