Description
Technical field
The utility model relates to a kind of apparatus for coating, is specifically related to a kind of apparatus for coating of repairing the lithium battery pole slice coating.
Background technology
The lithium battery pole slice coating process is that active material is applied on the pole piece, carries out drying then.In this process; Be coated on the lip-deep active material of pole piece, owing to receive the capillary influence of active material fluids, the drum phenomenon has appearred in coating edge part easily; The thickness that is the coating edge part is greater than the coating middle part, and this can influence the quality of production of lithium battery.Simultaneously during the lithium battery pole slice behind the rolling coating process, because the thicker chip phenomenon that also occurs easily after thickness adds up of thickness of pole piece edge coating part.At present, to above problem, normally improve the viscosity of coating material, but tend to reduce the flowability of coating material like this, the coating process difficulty is increased.Another kind of mode is the openings of sizes through adjustment coating spray nozzle both sides; As shown in Figure 3; Make the aperture area of the aperture area of nozzle 14 both sides that are coated with shower nozzle 13 less than the middle part; Thereby reduce the coating material that the spray nozzle both sides spray to the pole piece edge, reduce the coating thickness at pole piece edge; But it is big that this regulative mode is not only regulated difficulty, and regulating effect is bad.
The utility model content
The purpose of the utility model is in order to overcome pole piece coating layer thickness skewness in the lithium battery pole slice coating process process; Influence the problem of lithium battery pole slice coating quality; Provide a kind of and can repair the apparatus for coating that the pole piece coating layer thickness is evenly distributed the lithium battery pole slice edge coating.
The technical scheme of the utility model is:
A kind of apparatus for coating of repairing the lithium battery pole slice coating; It comprises the base that is oppositely arranged with deflector roll; Base upper surface is provided with guide chute; Be provided with two tool rests that can slide along guide chute in the guide chute, said two tool rest tops respectively level be provided with perpendicular and scraper that can move forward and backward and the positioner that is used to locate scraper with guide chute; The blade of said two scrapers is positioned at the same side of tool rest.Through regulating the position between two tool rests on the base, make two tool rests lay respectively at the place, both sides of the edge of pole piece; And then scraper on the adjusting tool rest and the spacing between the pole piece, the spacing between the blade that makes two scrapers and the lithium battery pole slice is identical with the thickness of lithium battery pole slice middle part coating material.Because the apparatus for coating of lithium battery pole slice painting process is to transmit through deflector roll; When lithium battery pole slice passes through the scraper place; If the drum phenomenon has appearred in place, lithium battery pole slice two edges, promptly the thickness of pole piece edge coating part is greater than pole piece middle part coating layer thickness, and the coating material that inclined to one side thickness portion is located in the lithium battery pole slice two edges will be struck off by scraper; The pole piece coating is evenly distributed, improves the coating quality of lithium battery pole slice.
As preferably, guide chute is a T type groove.Guide chute is that T type groove not only can play guide effect to tool rest; Can also carry out spacingly to tool rest, tool rest can not deviate from from guide chute top in the course of the work.
As preferably, the guide chute bottom surface is provided with by guide chute one end extends the strip through hole to the other end; Said base end face be provided with two pass the strip through hole and with respectively with the bolt of two tool rests through being threaded.Tool rest positions through bolt.When tool rest slided in guide chute, bolt was also along with tool rest moves in the strip through hole; After adjust the tool rest position, through bolt tool rest is positioned on the base, it is simple in structure, easy to operate.
As preferably, the guide chute closed at both ends, base upper surface is provided with the rectangular channel perpendicular with guide chute; Rectangular channel one end is connected with the guide chute middle part, and the other end is connected with the base side; And the rectangular channel bottom surface flushes with the guide chute bottom surface.Tool rest inlet when the rectangular channel that is communicated with the guide chute middle part is the tool rest installation.The guide chute closed at both ends can limit the moving range of tool rest, guarantees that tool rest moves in guide chute.
As preferably, scraper comprises head and shank, and the shank end also is provided with vernier knob; Said tool rest top is provided with the shoulder hole that is used to place scraper, and blade cover is located in the shoulder hole; Said positioner is a holding screw.The terminal vernier knob that is provided with of scraper shank can be finely tuned the spacing between scraper head blade and the pole piece, improves the uniformity of pole piece edge coating thickness and pole piece mid portion coating layer thickness.
As preferably, be provided with the collection frame below two scrapers.The collection frame can collect the coating material that strikes off from the pole piece edge to be recycled, and reduces cost.
The beneficial effect of the utility model is: can make the coating material consistency of thickness of pole piece edge and pole piece middle part, thereby improve the coating quality of lithium battery pole slice.
