Description
Technical field
The invention belongs to technical field of lithium-ion battery, more particularly, to a kind of pole piece coating sweep-out method and removing dress
Put.
Background technology
Lithium ion battery is widely used in digital product because energy density is high, self discharge is little, environmentally friendly, and
Recently as the development of unmanned plane, electric automobile, lithium ion battery also obtains more concerns, nowadays using equipment to battery
Energy density, internal resistance, the chemical property aspect such as cycle life put forward higher requirement.At present, in positive and negative electrode active matter
Material gram volume all perform to ultimate attainment in the case of, how to improve the skill that battery core capacity has become field of lithium further
Art bottleneck.
Fig. 1 is the structural representation of conventional batteries pole piece, can coat work during conventionally produced battery pole piece on empty paper tinsel C
Property material thus forming coating A, the blank of one section of uncoated active substance for soldering polar ear B, can be left in the end of empty paper tinsel C
Region D, then lug B is welded in this white space D.
In order to lift battery core energy density, in the industry in clear area by the way of being also coated with active substance in white space
Coating is similarly formed on domain, then again the coating in the soldering polar ear area in white space is removed, finally in lug to be welded
Area's soldering polar ear.
The method of the removing coating commonly used at present is that mechanical scraper removes method or foamed glue removes method.Mechanical scraper removes
Method is to be scraped off, using scraper plate, the coating being coated on paillon foil, but mechanical scraper removes the cleaning after method is difficult to ensure that coating removing
Degree, and scraper plate easily scratch staves sky paper tinsel.When the coating that method is removed on pole piece is removed using foamed glue, need in each pole
Ear welding region all sticks a piece of gummed paper, and operation is more, and production cost is too high；And cathode size aqueouss, are difficult to phase with gummed paper
Molten, the slurry on gummed paper surface can dissociate to gummed paper surrounding, leads to the coating surface density of its surrounding to thicken, thus having influence on battery core
Performance and thickness.
In order to overcome the shortcomings of both the above method, also proposed in the industry laser cleaning method.As Patent No.
The U.S. patent Nos of US8309880B2 disclose a kind of method of the coating removing on pole piece using laser, but this laser
Ablution still suffers from following deficiency：First, the method is cleaned by region with inert blowing gas pole piece while laser cleaning, with
Realize cleaning and the cooling of pole piece, but this can not coating on fully erased pole piece, laser beam can be affected clear to pole piece coating
Wash effect, and can not effectively collect the dust granules being eliminated, thus having influence on the security performance of battery core；Secondly, laser is clear
Heat can be produced during removing coating, and pass to light paper tinsel, light paper tinsel is heated inequality and effectively fixed and can produce deformation, thus shadow
After sound, operation makes.
The Chinese invention patent application of Publication No. CN105406028A discloses another kind of laser and removes pole piece coating
Method, the mode of coating area vac sorb to be removed on pole piece is fixed by the method, then adopts flat roof type laser beam to move
Coating except this region to be removed.But the method there is also some shortcomings：First, by the way of the fixing pole piece of vac sorb,
Need perforate on cleaning platform, thus realizing vac sorb pole piece, but pole piece and vacuum during pole piece fixing using vac sorb
The corresponding region of hole mouth and coating can cave inward under vacuum, make region to be cleaned deviate laser beam foucing, easily deposit
Clean sordid risk, lead to pole piece welding rosin joint；If vacuum hole nozzle aperture footpath is too small, the powder that pole piece cleaning produces
Dirt easily blocks hole, thus adsorption effect cannot be produced；Secondly, produced by laser burns pole piece, heat can constantly be delivered to
Cleaning platform, in batch production process, the temperature of platform can constantly raise, or even beyond temperature during pole piece cleaning, pole piece
Processing intermittent fever measures less than effective transfer, and the foil surface oxidation after leading to clean is serious, thus having influence on battery core performance.
Content of the invention
It is an object of the invention to provide a kind of side that can prevent the good removing pole piece coating of pole piece deformation, cleaning performance
Method and remove device.
To achieve these goals, the present invention takes following technical solution：
A kind of method removing pole piece coating, comprises the following steps：
Pole piece is positioned on cleaning platform, is provided with the circulating cooling pipeline of circulation cooling liquid in described cleaning platform；
With briquetting, pole piece is pressed on cleaning platform, described briquetting is provided with groove, described groove is by treating on pole piece
Cleaning area is exposed, and the side wall of described groove is provided with vacuum slot, described vacuum slot be arranged in described briquetting
Vacuum line connects；
With laser, calcination is carried out to the pole piece region that briquetting groove exposes, to dispose the coating in this region, laser cleaning
While pole piece coating, the cooling liquid in cleaning platform is lowered the temperature to pole piece, the powder that the vacuum slot on briquetting will produce
Dirt powder collection, coating is removed after finishing and is exposed foil by laser, completes to clean.
Pole piece coating remove device, including the cleaning platform for placing pole piece, is located at swashing above described cleaning platform
Shaven head, is provided with the circulating cooling pipeline of circulation cooling liquid in described cleaning platform；It is provided with briquetting on described cleaning platform,
Described briquetting is pressed on pole piece, and described briquetting is provided with groove, and described groove is corresponding with region to be cleaned on pole piece, described logical
Vacuum slot is provided with the side wall of groove, in described briquetting, is provided with the vacuum line connecting with described vacuum slot.
More specifically, described vacuum slot is arranged on one or more sides wall of described groove.
More specifically, it is provided with the circulating cooling pipeline of circulation cooling liquid in described briquetting.
More specifically, the vacuum of described vacuum slot is -10～-90Kpa.
