Description
[technical field]
The utility model relates to a kind of battery pole piece laser cutting head.
[background technology]
The each large Automobile Enterprises in the whole world expands a fierce contest in technical field of new energies, degree of reaching the decisive stage is competed for electrokinetic cell Development and Production, it is that charging and discharging currents is large, capacity is large that electrokinetic cell compares its feature with general battery, generally there are the different sizes such as 10 ampere-hours, 50 ampere-hours, 100 ampere-hours, 300 ampere-hours, along with demand growth, more high-power more jumbo electrokinetic cell may be there is.Die-cut or the rolling cut pole piece of power battery of the mode that existing cutting method adopts cutting die and punch press to combine substantially is to realize pole piece segmentation, adopt the mode of cutting die, cutting die rate of decay is exceedingly fast, change cutting die complex operation debug difficulties, frequent replacing cutting die cost is high and be difficult to ensure the uniformity demonstrate,proving each cutting die size, the pole piece burrs on edges cut out is large, metal fillings is many, cannot the qualified battery pole piece of output.
[utility model content]
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of structure simple, by laser cutting, effectively can remove the battery pole piece laser cutting head that cutting bits improve product percent of pass during cutting.
In order to solve the problem, the utility model by the following technical solutions:
A kind of novel battery pole piece laser cutting head, comprise housing, described shell one end is provided with the optical fiber of transmission laser, it is characterized in that: the other end of described housing is provided with focusing drawtube, be provided with in described focusing drawtube for the focusing lens to Laser Focusing, one end of described focusing drawtube is provided with the cutting head for laser injection, described cutting head can be arranged on described focusing drawtube movably to described focusing lens side, described cutting head overcoat has draft hood, one end open is provided with and the openend pumping chamber relative with battery pole piece to be processed between described draft hood and cutting head, described draft hood is provided with the bleed-off passage be communicated with described pumping chamber.
A kind of novel battery pole piece laser cutting head as above, is characterized in that: be provided with grid cylinder in described draft hood, and described grid cylinder is provided with the intercommunicating pore of pumping chamber described in multiple connection and bleed-off passage.
A kind of novel battery pole piece laser cutting head as above, it is characterized in that: described draft hood is provided with the bleeding point communicated with described bleed-off passage, described intercommunicating pore on described grid cylinder circumferentially, the orifice area of described intercommunicating pore along with described intercommunicating pore to described bleeding point distance from far near and from large to small.
A kind of novel battery pole piece laser cutting head as above, is characterized in that: described housing is provided with video camera, is provided with the speculum that the image that the laser penetrated in described cutting head carries out cutting can be reflexed to described video camera in described housing.
A kind of novel battery pole piece laser cutting head as above, is characterized in that: the inclined angle alpha of described speculum is 45 °.
The beneficial effects of the utility model have: by laser cutting, reduce burr, after the external aspiration pump of draft hood, when carrying out laser cutting, can take cutting bits away, improving yield rate; Because the pressure of bleeding near bleeding point side is large, and the orifice area of intercommunicating pore to along with intercommunicating pore to bleeding point distance from far near and from large to small, the air pressure of such each intercommunicating pore of balance, cutting bits can steadily be taken away by isostasy when cutting bits are taken away; The image by video camera can be observed, find out the quality of cutting, thus the height of cutting head or aspiration pump are regulated, guarantee that cutting is stable.

Fig. 2 is main sectional view of the present utility model;
Fig. 3 is explosive view of the present utility model.
[detailed description of the invention]
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of novel battery pole piece laser cutting head, comprise housing 1, housing 1 one end is provided with the optical fiber 2 of transmission laser, optical fiber 2 is located at housing 1 upper end, optical fiber 2 one end extend in housing 1, the other end of housing 1 is provided with focusing drawtube 3, focusing drawtube 3 is located at housing 1 lower end, be provided with for the focusing lens 4 to Laser Focusing in focusing drawtube 3, one end of focusing drawtube 3 is provided with the cutting head 5 for laser injection, cutting head 5 is located at focusing drawtube 3 lower end, cutting head 5 can be arranged on focusing drawtube 3 to focusing lens 4 side movably, cutting head 5 is threaded on focusing drawtube 3, Laser Focusing is reconciled by rotation focusing drawtube 3 or cutting head 5.Cutting head 5 overcoat has draft hood 8, and be provided with one end open between draft hood 8 and cutting head 5 and the openend pumping chamber 81 relative with battery pole piece to be processed, draft hood 8 is provided with the bleed-off passage 82 be communicated with pumping chamber 81.Be provided with grid cylinder 9 in draft hood 8, grid cylinder 9 is provided with the intercommunicating pore 91 of multiple connection pumping chamber 81 and bleed-off passage 82.Draft hood 8 is provided with the bleeding point 83 communicated with bleed-off passage 82, bleeding point 83 is connected with aspiration pump, when laser carries out cutting battery pole piece, aspiration pump is bled, cutting bits are inhaled in pumping chamber 81, entered in bleed-off passage 82, thus taken away by aspiration pump by intercommunicating pore 91, cutting bits on the battery pole piece of such well cutting are sucked away substantially, and raise the cost rate.Intercommunicating pore 91 on grid cylinder 9 circumferentially, the orifice area of intercommunicating pore 91 along with intercommunicating pore 91 to bleeding point 83 distance from far near and from large to small.Because the air pressure of bleeding near bleeding point 83 side is large, the orifice area of the near intercommunicating pore 91 of distance bleeding point 83 is little, and away from area large, the air pressure of bleeding of each intercommunicating pore 91 can be balanced like this, make the air pressure branch of bleeding in pumping chamber 81 even, cutting bits are evenly siphoned away.
Housing 1 is provided with video camera 6, is provided with the speculum 7 that the image that the laser of injection in cutting head 5 carries out cutting can be reflexed to described video camera 6 in housing 1, and speculum 7 can pass for lens laser, and the inclined angle alpha of speculum 7 is 45 °.Can make a video recording by video camera 6, the quality of cutting can be seen, thus focusing drawtube 3 is regulated, focus, reach the object of monitoring in real time.
