The dust collecting box has the advantages that: the dust collecting box can suck and collect the metal dust generated during the welding process in time, effectively prevent the meal dust from entering the inside of the pole unit, improve the safety and the electrical property of the battery and reduce the difficulty of cleaning the welded area of the tab; and the dust collecting box is convenient to use and has long service life and low cost, and is applied to various winding machines and to the dust removal treatment during the tab welding process of various lithium ion batteries.
Description
Technical field
The utility model relates to a kind of lithium ion battery and produces servicing unit, relates in particular to a kind of lithium ion cell polar ear welding dust-absorbing box.
Background technology
In the production process of lithium ion battery, lug need be connected by welding on the pole piece, but producing the metallic dust that is formed by utmost point powder, metal powder in the lug welding process drops, the metallic dust that drops is attached on the equipment or spread in the space, can enter utmost point group and cause the battery short circuit and the self discharge that are wound into, serious meeting causes the quick-fried spray of battery, reduces the electrical property of battery, and forms potential safety hazard.Especially lug weld cleaning is difficult, does not still have effective dust suppression so far, therefore, realizes the problem of timely and effective removal metallic dust, becomes the industry focal point.
The utility model content
Main purpose of the present utility model is at the problems referred to above, a kind of lithium ion cell polar ear welding dust-absorbing box is provided, in time absorb at the metallic dust that the lug weld drops in to welding process, product quality with effective assurance battery, reduce short circuit ratio, the self-discharge rate of battery, improve the security performance and the electrical property of battery.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of lithium ion cell polar ear welding dust-absorbing box, it is characterized in that it being to constitute by the dust leg of uncovered dirt-collecting box body, hermetically-sealed construction and the sweep-up pipe of the dust leg that is tightly connected, the horizontal narrow slit of dust leg by its sidewall setting be close to the described dirt-collecting box body bottom surface that its sidewall fixedly installs and be communicated with, dirt-collecting box body bottom surface is the setting that is inclined upwardly at the end with described slit.
The width of described horizontal narrow slit is 2-8mm.
The acclivitous angle of the relative horizontal plane in described dirt-collecting box body bottom surface is 30 °～60 °.
Described dirt-collecting box body bottom is provided with installing rack.
The beneficial effects of the utility model are: in time absorb the purpose of dust when having realized the battery pole ear welding, the setting that is inclined upwardly of dirt-collecting box body bottom surface is convenient to the metallic dust landing and is entered slit; Adopt the slit of wide 2～8mm to be beneficial to concentrating of negative pressure; After this dust-absorbing box was installed, most of metallic dust was absorbed, and can reduce the cleaning difficulty of lug weld, especially can effectively avoid metallic dust to enter in the utmost point group, reduce short circuit ratio, the self-discharge rate of battery, improve the security performance and the electrical property of battery, guarantee product quality, long service life.Through using proof, the utility model is easy to use, and input cost is low, is applicable to that the lug welding dust suction of various up-coilers and various types of lithium ion batteries is handled.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: installing rack in 1,2 sweep-up pipes, 3 dust legs, 4 horizontal narrow slits, 5 dirt-collecting box bodies, 51 box bottoms, 6 install screw, 7 outer installing racks.
Below in conjunction with drawings and Examples the utility model is described in detail.
The specific embodiment
Fig. 1 illustrates a kind of lithium ion cell polar ear welding dust-absorbing box, it is characterized in that it being to constitute by the dust leg 3 of uncovered dirt-collecting box body 5, hermetically-sealed construction and the sweep-up pipe 2 of the dust leg 3 that is tightly connected, the horizontal narrow slit 4 of dust leg 3 by its sidewall setting be close to the aforementioned dirt-collecting box body bottom surface 51 that its sidewall fixedly installs and be communicated with, dirt-collecting box body bottom surface 51 is the setting that is inclined upwardly at the end with aforementioned slots 4.In actual fabrication, the aforementioned dirt-collecting box body bottom surface acclivitous angle of 51 relative horizontal planes is 30 °～60 °, adopts 45 ° to be best.The width of aforementioned levels slit is 2-8mm.5mm is for the most suitable in actual applications.Be provided with installing rack in dirt-collecting box body 5 bottoms.In the present embodiment, dirt-collecting box body 5 has adopted uncovered square box body, and a side of square box bottom 51 is connected horizontal narrow slit 4 positions, and is communicated with dust leg 3 by horizontal narrow slit 4; Another side that square box bottom 51 is relative with aforementioned side is inclined upwardly and is connected with box side wall, forms slideway under the dust.Installing rack comprises interior installing rack 1 and the outer installing rack 7 that is separately positioned on dirt-collecting box body 5 bottom inside and the outside, is provided with 3 installation screws simultaneously and is used for fixing the whole dust-absorbing box device that the utility model provides on installing rack 7.The parts of device all adopt metal material, and are wear-resistant, long service life.
The course of work of the present utility model and principle:
Generally, the soldering tip of up-coiler (not shown) is arranged on the support pallet of equipment, during use, lithium ion cell polar ear is welded the soldering tip below that dust-absorbing box is installed in the up-coiler soldering polar ear, by being completely fixed of interior installing rack 1 and outer installing rack 7 and installation screw 6 usefulness screws realization dust-absorbing box and up-coiler.Sweep-up pipe 2 connects the dust catcher (not shown).Up-coiler is when producing, and the metallic dust that the lug weld drops directly falls into dirt-collecting box body 5, because the suction function at horizontal narrow slit 4 places, metallic dust enters dust leg 3 thereupon, and enters into dust catcher by sweep-up pipe 2.The purpose that dust suction was handled when thus, application the utility model had been realized the battery pole ear welding.The 51 relative horizontal planes setting that is inclined upwardly in dirt-collecting box body bottom surface is convenient to the metallic dust landing and is entered slit 4.Adopt the horizontal narrow slit 4 of wide 2～8mm, be beneficial to concentrating of negative pressure.After this dust-absorbing box was installed, most of metallic dust was absorbed, and can reduce the cleaning difficulty of lug weld; Especially can effectively avoid metallic dust to enter in the utmost point group, improve every performance of battery.
The above only is a preferred embodiment of the present utility model, is not shape material of the present utility model and structure are done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
