Accordingly, as a device for manufacturing a positive electrode plate, a negative electrode plate, and the like used in these batteries, a device for manufacturing a positive electrode plate is widely demanded.
In the prior art, a wet process method for manufacturing a plate is proposed, specifically, a carrier is passed through a tank containing paste, the paste is filled in the tank onto or into the carrier, and the plate is shaped by a drying process.
However, when a carrier having a three-dimensional skeleton such as foamed nickel is immersed in a paste containing an active material, the water content and viscosity of the paste have a large influence on the effect of filling the active material. Therefore, in the production line for manufacturing the electrode plate, the weight of the manufactured electrode plate is greatly deviated according to the change of the water content and the viscosity of the paste, and the paste cannot be effectively filled in the carrier when the viscosity is too large or too small, so that the uniform filling effect cannot be obtained.
For example, during a prolonged filling process, the dried carrier may carry away moisture in the paste, so that the moisture content of the paste gradually becomes lower. After the water content of the paste is reduced, the paste is easy to have excessive viscosity, so that the paste cannot be effectively filled in a carrier, and the quality of the manufactured polar plate may be reduced.

Preferably, in the electrode plate manufacturing apparatus, the paste tank carries the paste containing at least the electrode active material, a thickener, and a liquid solvent.
Preferably, in the electrode plate manufacturing apparatus, the carrier is a porous metal skeleton in a belt shape, and the conveying section is a plurality of conveying rollers that support and convey the porous metal skeleton at a fixed speed.
Preferably, in the electrode plate manufacturing apparatus, the humidifying unit is a sprayer, and the liquid solvent is sprayed onto the porous metal skeleton at a fixed spraying speed.

Detailed Description
Hereinafter, embodiments of the present utility model will be described with reference to the drawings. However, in the embodiments described below, various limitations technically preferable for the implementation of the present utility model are added. Accordingly, the scope of the technology of the present disclosure is not limited to the following embodiments and examples. The size, shape, and proportional relation in the example of the drawing are merely illustrative, and are not specific. In the drawings, the same components as those in the embodiments are denoted by the same reference numerals, and overlapping description thereof is omitted.
Fig. 1 is a block diagram schematically showing a functional configuration of an electrode plate manufacturing apparatus 100 according to an embodiment of the present utility model. As shown in fig. 1, the electrode plate manufacturing apparatus 100 includes a humidifying unit 110, a paste tank 120, and a conveying unit 130 for conveying the carrier 10.
The electrode plate manufacturing apparatus 100 may be used for manufacturing a positive electrode plate or a negative electrode plate, as needed. For example, when the electrode plate manufacturing apparatus 100 is used for manufacturing a positive electrode plate, for example, a spongy band-shaped porous metal skeleton, an etched metal foil, or the like is transported as the carrier 10 to the electrode plate manufacturing apparatus 100. As a specific example, for example, the foamed nickel skeleton is transported as the carrier 10 to the electrode plate manufacturing apparatus 100. In addition, for example, when the electrode plate manufacturing apparatus 100 is used for manufacturing a negative electrode plate, the metal material of the sponge-like band-shaped porous metal skeleton or the etched metal foil serving as the carrier 10 is different from that of the positive electrode plate, and is, for example, a foam copper skeleton or the like. The carrier 10 may be made of a composite material of a carbon material and a metal, for example, as required.
The humidifying unit 110 humidifies the carrier 10 passing through the humidifying unit 110 along the path of the conveying unit 130. The humidifying unit 110 is implemented by, for example, a liquid-spraying sprayer, a liquid tank for carrying liquid, or the like, and the specific configuration thereof will be described later, but any configuration may be used as long as it is capable of at least moisturizing the surface of the carrier 10.
The paste tank 120 is provided at a later stage of the humidifying section 110, and carries paste 121, and the paste 121 has at least an electrode active material. The carrier 10 is filled with paste 121 by passing the carrier 10 humidified by the humidifying part 110 through the paste tank 120 along the path of the conveying part 130. The structure and shape of the paste tank 120 are not limited as long as it is a case capable of carrying the paste 121. The paste 121 contains a metal oxide, a composite metal oxide, or the like as a positive electrode active material when the electrode plate manufacturing apparatus 100 is used for manufacturing a positive electrode plate, and contains a metal oxide, a composite metal oxide, a graphite material, or the like as a negative electrode active material when the electrode plate manufacturing apparatus 100 is used for manufacturing a negative electrode plate. The paste 121 also has a thickener and a liquid solvent, and is a liquid having a certain viscosity. The thickener is, for example, polyvinyl alcohol or the like for increasing the viscosity of the paste 121, and the liquid solvent is preferably water, which is capable of dissolving or dispersing the electrode active material and the thickener, but may be other liquids, for example, an organic solvent such as acetone, and the viscosity of the liquid solvent is less than or equal to that of the paste 121 for electrode plate production. In the case of a specific viscosity of the liquid solvent, the thickener may not be added. The paste 121 may further include other additives, such as an adhesive and a conductive agent, in addition to the above-described components.
The electrode plate manufacturing apparatus 100 may further include a post-processing unit (not shown) such as a drying unit, a calendaring unit, and a dividing unit provided at a later stage of the paste tank 120, if necessary, but any of these post-processing units is not essential. The drying section is configured by a drying furnace, an air dryer, or the like, and dries the paste-filled electrode plate, the rolling section rolls the dried electrode plate by a rolling roller, and the dividing section divides the electrode plate into sizes corresponding to the use of the electrode plate by a divider.
The transport unit 130 may be any structure capable of transporting the carrier 10 in a fixed path. For example, by a conveyor roller or belt that can transport the carrier at a fixed speed.
By passing the carrier 10 humidified by the humidifying unit 110 through the paste tank 120 along the path of the conveying unit 130, the carrier 10 humidified is not dried but is supplied with water, so that the water lost by the paste 121 when the carrier 10 passes through the paste tank 120 can be supplemented, and the paste 121 can be easily maintained at a constant water content and viscosity, so that the quality of the manufactured electrode plate can be maintained uniform even after the paste filling operation is continuously performed for a long period of time, and the paste filling efficiency of the carrier 10 can be improved.
Hereinafter, as a specific example, the plate manufacturing apparatus 100 for manufacturing a positive electrode plate by transporting a foamed nickel skeleton as a carrier 10 to the plate manufacturing apparatus 100 and carrying a paste 121 containing nickel oxide as a positive electrode active material in a paste tank 120 will be described as an example of the plate manufacturing apparatus 100 for manufacturing a positive electrode plate.
Fig. 2 is a schematic diagram schematically showing the structure of an apparatus 100 for manufacturing a polar plate according to an embodiment of the present utility model. As shown in fig. 2, a foamed nickel skeleton (a porous metal skeleton) which is a strip-like body is used as the carrier 10. The carrier 10 is transported to the electrode plate manufacturing apparatus 100 by the plurality of transport rollers 131, and moves at a fixed speed in synchronization with the rotation of the plurality of transport rollers 131 by the supporting action of the plurality of transport rollers 131 in the electrode plate manufacturing apparatus 100. The plurality of conveying rollers 131 function as the conveying section 130. As the plurality of transfer rollers 131 rotate, the nickel foam skeleton serving as the carrier 10 first passes through the humidifying section 110, is added with water, and then passes through the paste tank 120 in which the paste 121 is carried.
Hereinafter, the structural features of the humidifying unit 110 will be specifically described. Fig. 3 is a schematic diagram schematically showing the structure of the humidifying unit 110A according to an embodiment of the present utility model. As shown in fig. 3, the function of the humidifying portion 110A is achieved by at least one atomizer 111. As the plurality of conveying rollers 131 rotate, the at least one atomizer 111 sprays liquid onto the foamed nickel skeleton as the carrier 10, for example, at a fixed discharge speed, so that the foamed nickel skeleton is uniformly humidified. The liquid is, for example, the same type of liquid as the liquid solvent contained in the paste 121 in the paste tank 120, and is preferably water.
The atomizer 111 is, for example, an ultrasonic vibration atomizer, and atomizes a liquid by ultrasonic vibration and ejects the liquid from a nozzle thereof. In the drawings, the plurality of sprayers 111 are provided in the vertical direction, but the number of sprayers 111 and the direction in which the liquid is discharged are not limited to this, and the liquid may be discharged only to one surface of the strip-shaped nickel foam skeleton.
Fig. 4 is a schematic diagram schematically showing a structure of a humidifying unit 110B according to another embodiment of the present utility model. As shown in fig. 4, the function of the humidifying section 110B is realized by the liquid tank 112 that carries the humidifying liquid 113. As the plurality of transfer rollers 131 rotate, the nickel foam skeleton as the carrier 10 is sequentially immersed in the humidifying liquid 113 in the liquid bath 112. Further, the time for which the carrier 10 is immersed in the humidifying liquid 113 is controlled by controlling the speed of the conveying roller 131, and it is preferable that the carrier 10 is passed through the liquid bath 112 at a fixed speed so that the carrier 10 is uniformly humidified. The humidifying liquid 113 in the liquid tank 112 is, for example, the same type of liquid as the liquid solvent contained in the paste 121 in the paste tank 120, and is preferably water.
In order to further make the viscosity of the paste 121 in the paste tank 120 uniform, it is also conceivable to further add a stirrer to the paste tank 120. Fig. 5 is a schematic diagram schematically showing the structure of an apparatus 100A for producing a polar plate, in which a stirrer 122 is added, according to an embodiment of the present utility model. As shown in fig. 5, the agitator 122 is provided inside the paste tank 120, and agitates the paste 121. The agitator 122 is not particularly limited in structure, and is, for example, a rotary agitator having a plurality of agitating blades provided at the bottom of the paste tank 120, although not specifically shown. The paste 121 is stirred by the stirrer 122, and the viscosity of the paste 121 in the paste tank 120 is easily maintained in a uniform state all the time, so that the quality of the produced electrode plate is uniform and stable.
Although the above description has been made with reference to fig. 2 to 5 as an example of the electrode plate manufacturing apparatus for manufacturing the positive electrode plate, the electrode plate manufacturing apparatus for manufacturing the negative electrode plate may have a similar structure, and the above-described embodiments may be combined or modified as long as the humidifying unit is used to humidify the support so that the dried support has a certain amount of moisture, and the moisture in the paste does not decrease with the passage of time during the filling process.
The present utility model can be variously omitted, substituted or modified within a range not departing from the gist of the present utility model. These embodiments and modifications are included in the scope and gist of the utility model, and are included in the utility model described in the claims and their equivalents.
