The interface of the micro pump is communicated with the feed channel, the servo motor is used for driving the micro pump to work, and residual slurry in the feed channel can be absorbed accurately or slurry is replenished into the feed channel during coating to ensure that the head and tail thickness of the slurry coated at the intervals of a coated body are uniform, so that the problems of large thickness of the head and trailing of the tail are solved.
Description
Technical field
The utility model belongs to the base material coating manufacturing equipment technical field of lithium ion battery, relates in particular to a kind of extrusion coated head of the coating thickness revised of extrusion coating machine.
Background technology
Producing in lithium ion battery process, be coated with the operation that is absolutely necessary, be the critical process that directly affects the properties such as battery security, capacity and uniformity.Domestic conventional coating method has two kinds at present: transfer type coating and squash type coating.Transfer type applying structure complexity, equipment debugging is loaded down with trivial details.And extrusion coater technology is increasingly mature, it is simple in structure, facility compact, and debugging is convenient, by increasing producer, is used.But being coated on, realizes while being intermittently coated with squash type, what adopt is that high speed transfer valve is realized, because the high speed piston of high speed transfer valve moves up and down, can produce to slurry thrust or the pulling force of moment, cause the existence coating problem that intermittently position head is partially thick and afterbody formation is trailed.
In order to solve thick head and the problem of trailing in prior art, people have proposed some solutions, as Chinese patent CN102657255A, a kind of intermittent extrusion type coating machine, comprise high speed transfer valve and extrusion head, extrusion head is provided with the interface being communicated with the cavity of extrusion head, interface is connected to a slurry buffer tank by pipeline, on slurry buffer tank, the position of high sub-pipes junction offers pump orifice, pump orifice connects the aspirator of bleeding with son, in pipeline, be also provided with the switch valve for controlling pipeline break-make, switch valve and the interlock of high speed transfer valve, when the normal coating of extrusion head and intermittence, switch valve is closed, cutting out pipeline path, when high speed switch valve cuts off feeder channel and recovers feed, switch valve is opened and is made pipeline unobstructed.This coating machine adopts the cooperation of high speed transfer valve, switch valve and aspirator, when initial and feed stops at extrusion head feed, all the slurry at extrusion head sealing place is carried out to suck-back, to avoid producing the problem that dispense tip is thick and trail.But, this coating machine in actual applications, what adopt due to it is the mode of vacuumizing and adsorbing, use capacity of returns quantitatively to control, its reason is because air has dilatancy, the frictional force to slurry that the inner-walls of duct being connected with switch valve with it when switch valve produces is less (is mainly the solute evaporation of slurry at pipeline, due to concentration retrogradation), the suction of vacuum suction sometimes deficiency so that the slurry at the sealing place of dispense tip can stay, if adopt excessive suction, can be excessive because of absorption affinity, and make backflow of slurry too much, and produce new problem, as thin, tail is thin etc., also can affect the quality of coating, in addition, this coating machine, also in the problem of mechanism's complexity, is restricted the miniaturization more of coating machine, and space hold is also larger, it is also not too convenient that debugging is got up, and this coating machine also exists in the process of coating, if there is the phenomenon problem of quantitative material supplementing in time of scumbling.
And this coating machine, in the process of intermittently coating, is coated on the slurry being coated with on body and tends to occur the inhomogeneous of coating, and some places are coated with thick, and some places are coated with thin, have affected quality and the Painting effect of coating.
Utility model content
