The present invention protects a kind of laser cutting dust pelletizing system; dust cover is adopted to impale the space of cutting between backing plate and laser head; and the inner space of dust cover communicates with dust-proof blower fan; in the process that laser head cuts sheet stock, effectively remove under the suction function that the dust sticking to sheet stock surface can provide at dust-proof blower fan.
The laser cutting dust pelletizing system of present embodiment is used for carrying out cutting to the sheet stock of the electrodes of lithium-ion batteries shown in Fig. 1 and forms lug 11.Sheet stock comprises and stays white region shown in the dispensing area shown in D position and E position, and sheet stock ceaselessly moves horizontally continuously along direction shown in arrow, and laser head carries out cutting according to the dotted line shown in F position to sheet stock and forms lug 11.
Please refer to Fig. 2, the laser cutting dust pelletizing system of present embodiment comprises laser head 34, dust absorption fan 35, protective cover 26, cutting backing plate 23, ion blower, speed control valve 24, dust shield 27, first sweep-up pipe 28, second sweep-up pipe 36, dust-absorbing box 32, and laser head 34, dust absorption fan 35, protective cover 26 can all be arranged on base.
Wherein, cutting backing plate 23 is arranged on base by pad bearing 33, for supporting sheet stock, laser head 34 is arranged on the top of cutting backing plate 23, lug is formed for carrying out cutting to sheet stock, protective cover 23 is around between laser head 34 and cutting backing plate 23, and one end of the first sweep-up pipe 28 communicates with dust-proof blower fan 35, and the other end communicates with the inner space of protective cover 26.In present embodiment, first sweep-up pipe 28 can communicate with the sidepiece of protective cover 26, dust shield 27 is also installed in the sidewall outside of protective cover 23, the inner space of protective cover 23 also arranges at least one suction port communicated with dust shield 27, dust shield 27 communicates with the other end of the first sweep-up pipe 28, the quantity of suction port and position can be arranged according to specific needs, such as suction port can have two groups, often group has one, be separately positioned on cutting backing plate 23 above sidepiece and rear portion form front suction port 29 and rear suction port 31, also by fixed head 30, each suction port is fixed in protective cover 26.
Shape, the size of protective cover 23 and dust shield 37 all can be arranged flexibly.Protective cover 23, for the space between closed laser head 34 and cutting backing plate 23, under the suction function that the dust in this confined space is provided at dust absorption fan 35 as much as possible, is extracted out by the first sweep-up pipe 28.The dust cover 37 of the present embodiment forms front opening comparatively greatly, and the cone-shaped cavity that rear end is less, is convenient to by the dust in each suction port sucking-off protective cover 23.In a kind of embodiment, protective cover 23 is square, and its sidewall comprises the antetheca corresponding with the direction that sheet stock seesaws and rear wall, and antetheca comprises the transparent prevention plate that preventing laser destroys, the situation in convenient operation personal observations protective cover 26.Dust-absorbing box 32 is arranged on pad bearing 33, and is positioned at immediately below cutting backing plate 23, makes pad bearing 33 between dust-absorbing box 32 and cutting backing plate 23.One end of second sweep-up pipe 36 communicates with dust-proof blower fan 35, and the other end communicates with the inner space of dust-absorbing box 32.After configuration dust shield case 32, it can adsorb the dust produced the process of laser cutting sheet stock below cutting backing plate 23, matches, remove from all angles and position the dust remained in sheet stock more fully and effectively with each suction port in protective cover 26.
First sweep-up pipe 28 and the second sweep-up pipe 36 can arranging flow control valve all as required, for regulating the throughput of this pipeline, thus changing the size of negative pressure in protective cover 36 as the case may be flexibly.
Incorporated by reference to Fig. 3 to Fig. 6, the middle part of cutting backing plate 23 has sheet stock support zone, for supporting thinner sheet stock, the both sides of this sheet stock support zone also arrange the inlet channel and bleed-off passage that communicate with sheet stock support zone respectively, the surface (especially side) of cutting backing plate 23 also has the ion wind air admission hole 232 and ion wind aspirating hole 231 that communicate with inlet channel and bleed-off passage respectively, ion blower is communicated with ion wind air admission hole 232 by a tracheae, for providing ion wind to sheet stock support zone, to remove electrostatic, more effectively to remove the dust sticked on sheet stock, dust absorption fan 35 is communicated with ion wind aspirating hole 231 by another root tracheae.Further, be connected on the tracheae between ion blower and ion wind air admission hole 232 and go back installation rate control valve, for the flow of flexible modulation ion wind.
Shape and the large I of cutting backing plate 23 and sheet stock support zone thereof are arranged as required flexibly, sheet stock support zone can be corresponding with the laser cutting region of laser head, in such as, embodiment in figure, at its sheet stock support zone, the groove 233 that multiple bottom communicates is set, the bearing of trend of groove 233 is vertical with the proal direction of sheet stock, and the bottom of groove 233 also communicates with inlet channel and bleed-off passage, connecting portion between adjacent two grooves 23 upwardly forms the brace rod 234 of strip, little lower large taper is presented in its cross section, and top width only has 0.05mm.The effect of brace rod 234 has two, during laser cutting pole piece, pole piece has the trend of a distortion downwards under the effect of laser and dust absorption fan, the pole piece material strip simultaneously tightened changes through laser cutting backward pull also can produce distortion, had the support supporting rib, one can prevent above-mentioned distortion, and two can utilize ion wind to destatic more easily, make dust more easily depart from pole piece under the effect of dust absorption fan, thus reach the object of effective dedusting.
Native system is when reality uses, before laser cutting starts, first adjustment equipment is needed, confirm the cutting path of laser on pole piece sheet stock applying area, because in laser cutting process, pole piece sheet stock ceaselessly travels forward, and in order to repeat to cut out the cutting path shown in F position in as Fig. 1 on pole piece sheet stock, laser should be the relative cutting path shown in C position in such as Fig. 4 relative to the path of fixed cutting backing plate 23.Avoid as much as possible cutting the brace rod on backing plate, afterwards when pole piece sheet stock is transported to laser instrument cutting zone, laser head and dust absorption fan and ion blower start, negative pressure is formed very soon in protective cover, the dust that the dust produced in laser cutting process and pole piece sheet stock adhere in course of conveying, after ion wind destatics, is siphoned away by dust absorption fan by ion wind aspirating hole, dust-absorbing box and front and back suction port on cutting backing plate.
Laser cutting dust pelletizing system structure of the present invention is simple, with low cost, easy to use, can be used in all kinds of laser cutting parameter, especially in the lug cutting technique of lithium-ions battery pole piece, effectively can clean the size particles dust on the pole piece sheet stock surface adhered at the volley, the dust that particle diameter is less than 5.0 μm can be removed, while the later process of battery production provides safeguard, also effectively improve battery production efficiency, decrease potential safety hazard.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
