Detailed description of the invention
Also by reference to the accompanying drawings the application is described in further detail below by specific embodiment."front", "rear" described in literary composition, "left", "right", " on ", D score all with the laying state of the cutting backing plate of the battery pole piece cutter sweep in accompanying drawing for reference.
As shown in Figure 1, the embodiment of the present application provides a kind of battery pole piece cutter sweep, comprises cutting backing plate 10, laser instrument 20, type laser light-path structure 30, laser scanning mirror 40 and field lens 50.Wherein, laser instrument 20, type laser light-path structure 30, laser scanning mirror 40 and field lens 50 connect successively, thus produce and control transmit direction and the travel path of laser.
Cut backing plate 10 for the support cells pole piece when cutting, simultaneously also for removing the dust produced in cutting process.Particularly, see Fig. 2 to 4, cutting backing plate 10 comprises backing plate housing 100, dodges hole 101, cushion block 102, backing plate adsorption hole 103, cushion block adsorption hole 104, fixed support bar 105 and sweep-up pipe interface 106.
Backing plate housing 100 is hollow structure, is the agent structure of cutting backing plate 10.The upper surface of backing plate housing 100 is cut surface 100a, and when carrying out laser cutting, battery pole piece will against cut surface 100a and advance.Dodge hole 101 and cushion block 102 to cooperatively interact the escape groove 106 that can be formed for dodging laser.Particularly, dodge hole 101 and be arranged on cut surface 100a, and communicate with the inside of backing plate housing 100, the cross section of dodging hole 101 and cushion block 102 is triangular structure, and the shape of the two is consistent.Wherein, the size of cushion block 102 is less than the size dodging hole 101, cushion block 102 is fixed on dodges within hole 101, the upper surface of cushion block 102 is exposed face 102a, exposed face 102a is used for support cells pole piece and is positioned at the part dodged within hole 101, to prevent battery pole piece because of the subnormal ambient of backing plate housing 100 inside when dedusting is welded by the inside of dodging hole 101 and be inhaled into backing plate housing 100.Cushion block 102 and dodge contactless position between hole 101, therebetween formed once circle be escape groove 107.In addition, in order to ensure the planarization of the other parts of this part and battery pole piece, exposed face 102a is concordant with cut surface 100a.
See Fig. 1, when carrying out laser cutting, field lens 50 is arranged on the top of cushion block 102, and makes the light path of laser aim at escape groove 107.The direct of travel of battery pole piece is along the length direction on a leg-of-mutton limit, and laser beam then moves along escape groove 107 is triangular in shape.Like this, only need adjust the gait of march of laser beam and battery pole piece, just can cut out the rectangle lug shape of protrusion on battery pole piece.And by the speed that transmission interval duration and the laser beam of adjustment laser beam are advanced on the direct of travel being parallel to battery pole piece, just can adjust the interval of lug and width, and without the need to the structure of the travel path that changes laser beam and escape groove 107.And the height of lug is owing to being subject to the high restriction of the triangular-section of dodging hole 101 and cushion block 102, directly cannot adjusting, needing the mode by changing cutting backing plate 10 to regulate.Wherein, the cross section of dodging hole 101 and cushion block 102 is preferably isosceles triangular structure, like this when the direct of travel of battery pole piece is advanced along the length direction on the base of isosceles triangle, as long as ensure that laser beam just can ensure along the gait of march of two waists of isosceles triangular structure is identical the lug shape cutting out rectangle.
In order to coordinate the demand of laser cutting parameter, cut surface 100a and exposed face 102a can be designed as the plane or curved surface that cooperatively interact.Wherein, for plane, curved design is more conducive to the laminating of battery pole piece and cut surface 100a and exposed face 102a.In order to make cushion block 102 possess enough intensity, the thickness of cushion block 102 is preferably not less than 1mm, but also need not be blocked up, is no more than the thickness of backing plate housing.Cutting backing plate 10 can be used alone, and also can be embedded in large flat cutting table or circular cutting roller and use.
The width of escape groove 107 can regulate within the scope of 0.1 ~ 10mm, narrow, laser likely cuts on cut surface 100a or exposed face 102a, wide, likely cause the battery pole piece part near section drop and fill in the inside of escape groove 107, cause deformation or affect normal cutting operation.
Along with the increase of escape groove 107 width, the trend of battery pole piece tenesmus is more obvious, even and if battery pole piece can not fill in the inside of escape groove 107, also likely scratched by the drift angle of cushion block 102.Therefore, cushion block 102 in the present embodiment adopts leg-of-mutton three limits all by the cross-sectional structure of round-corner transition.The structure of fillet is comparatively level and smooth, not easily scratches battery pole piece.The radius of fillet can adjust as required.
Because there is significant impact the position of cushion block 102 for the size of escape groove 106, therefore cushion block 102 needs to be firmly fixed, and as shown in Figure 4, in the present embodiment, cushion block 102 is fixed by fixed support bar 105 and backing plate housing 100.Particularly, the base plate 100b (see Fig. 3) of backing plate housing 100 is provided with screwed hole (not shown), screwed hole can be set directly at dodges immediately below hole 101, one end of fixed support bar 105 and the lower surface 102b of cushion block 102 fix, the other end of fixed support bar 105 is provided with external screw thread, and fixed support bar 105 is undertaken being threaded fixing by external screw thread and screwed hole.
In the present embodiment, backing plate adsorption hole 103 and cushion block adsorption hole 104 are all as adsorbing powder dust.Wherein, a large amount of backing plate adsorption holes 103 is arranged on cut surface 100a in array, each backing plate adsorption hole 103 all communicates with the inside of backing plate housing 100, and cushion block adsorption hole 104 is then evenly distributed on cushion block 102, and runs through cushion block 102 along the thickness direction of cushion block 102.Like this, when bled in the inside of backing plate housing 100 operation time, backing plate adsorption hole 103 and cushion block adsorption hole 104 just by pumping airflow by battery pole piece adsorption on surface, and dust welding produced in time is drawn onto the inside of backing plate housing 100 fast by backing plate adsorption hole 103, cushion block adsorption hole 104 and escape groove 107.Sweep-up pipe for the ease of the dust collecting system with outside is connected, and in the present embodiment, also the special sidepiece at backing plate housing 100 is provided with a sweep-up pipe interface 106.The parameter such as air quantity, blast of dust collecting system all can adjust as required.
According to parameters such as the sizes of cut surface 100a, exposed face 102a and battery pole piece, the aperture of backing plate adsorption hole 103 and cushion block adsorption hole 104 can adjust within the scope of 0.1 ~ 10mm.
The battery pole piece cutter sweep that the present embodiment provides leads to the structure significantly simplifying escape groove, significantly can also promote dust removing effects simultaneously.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for a person skilled in the art, the application can have various modifications and variations.Within all spirit in the application and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the application.
