Description
Technical Field
The invention relates to the field of battery production, in particular to the field of grid production.
Background
The traditional lead-acid battery comprises a positive plate, a negative plate, a partition plate, electrolyte and a shell, wherein positive and negative active substances are respectively coated on the positive plate and the negative plate, and the traditional lead-acid battery has the defects of low utilization rate of the active substances on the plates, easy falling of the active substances, easy layering of the electrolyte and the like.
The horizontal battery adopts bipolar polar plates, and the polar plates are horizontally arranged, so that electrolyte in the battery is not easy to layer. In the process of charging and discharging of the horizontal battery, current enters the side plate from one end, enters one pole of the first bipolar unit through the partition plate, then uniformly enters the other pole through the grid, and then reaches the other end, so that the current circuit is short, the resistance is small, the active substances are uniformly distributed, the conductive distance is short, the current density is uniformly distributed, and the application range of the horizontal battery is wider and wider.
The bipolar plate of the horizontal battery adopts positive and negative active materials to be coated and filled at two ends of a grid respectively, and an active material isolation belt is reserved between the positive and negative plates, so that a connecting strip and a lug between batteries can be omitted. The grid is generally formed by weaving composite wires made of core materials coated with metal or metal alloy, wherein the core materials play a supporting role, the strength of the woven grid is improved, and the grid is prevented from deforming in the using process. The traditional composite wires for weaving the grid are all cylindrical, and the cylindrical side area is the smallest under the condition of the same volume and length, so that the contact area between the composite wires for weaving the grid and an active substance is the smallest, the bonding force between the active substance and the grid is not strong, the composite wires are easy to fall off from the grid, and the storage battery is easy to be scrapped due to short circuit.
Disclosure of Invention
The invention aims to provide a weaving method of a grid, which can increase the contact area between the grid and an active substance.
In order to achieve the purpose, the technical scheme of the invention is as follows: the grid weaving method comprises the following steps:
fixing, namely placing coiled core materials on a fixing roller for fixing the core materials, pulling the end parts of the core materials, controlling the core materials to sequentially pass through a supporting double roller for guiding the core materials, a coating channel for coating molten metal or metal alloy on the periphery of the core materials, a supporting mechanism for supporting formed composite wires and a material supplementing mechanism for filling metal or metal alloy at the worn part of the composite wires, and enabling the core materials to be clamped into grooves on two supporting rollers;
secondly, filling, namely adding molten metal or metal alloy into a storage box capable of storing the metal or metal alloy before coating the metal or metal alloy on the periphery of the core material, and turning on a switch on the storage box until the molten metal or metal alloy in the storage box flows out;
coating, namely arranging a cooling water pipe for cooling the metal or the metal alloy outside the coating channel and the material supplementing mechanism, and communicating the cooling water pipe with an external water pipe; pulling the core material to enable the core material to move relative to the coating channel, the supporting mechanism and the material supplementing mechanism, so that the metal or the metal alloy is coated on the periphery of the core material, and the metal or the metal alloy coated on the periphery of the core material is pressed into a triangular prism shape; clamping two corners of the composite wire into the supporting mechanism; adjusting the angle of the composite wire entering the material supplementing channel to ensure that the abraded part of the composite wire is opposite to the metal or metal alloy flowing out of the material supplementing channel;
(IV) cutting the core material which is not coated with the metal or the metal alloy, and cutting the composite wire into warp threads and weft threads with the length longer than that of the warp threads;
weaving, namely taking at least three warps to form a vertical weaving unit, and taking at least one weft to form a horizontal weaving unit; enabling the horizontal weaving unit to be vertical to the vertical weaving unit, enabling warps and wefts to be orderly arranged, enabling odd number wefts of the horizontal weaving unit to penetrate through the upper portion of odd number warps and the lower portion of even number warps of the vertical weaving unit, and enabling even number wefts to penetrate through the lower portion of odd number warps and the upper portion of even number warps;
(VI) weaving for the second time, namely sequentially taking a second group of vertical weaving units and a second group of horizontal weaving units, continuing the counting of the last weaving unit by using the wefts and the warps in the second group of horizontal weaving units and the second group of vertical weaving units, and repeating the steps by using the horizontal weaving units to enable the even number of wefts in the vertical weaving units to pass through the lower part of the odd number of warps and the upper part of the even number of warps; repeating the steps until the weaving is finished;
cleaning, namely closing a switch after weaving is finished, and cleaning molten metal or metal alloy in the cladding mechanism and the material supplementing mechanism; and disconnecting the external water pipe from the cooling water pipe, and cleaning water in the cooling water pipe.
After the coiled core material is fixed on the fixed roller, when the end part of the core material is pulled, the coiled core material cannot move, the support roller guides and supports the core material, the core material is firstly placed in the coating channel, the support mechanism and the material supplementing mechanism, and when molten metal or metal alloy is added, the metal or metal alloy can directly flow to the periphery of the core material, so that the waste of the metal or metal alloy is avoided.
And (3) when the cladding is carried out in the step (three), molten metal or metal alloy flows to the periphery of the core material, and when the metal or metal alloy is cooled, the metal or metal alloy is fixed on the periphery of the core material to form the composite wire. After the coating is finished, the composite wire moves along the supporting mechanism and enters the material supplementing channel before use, and the abraded part is supplemented with materials in the moving process.
In the actual production process, when the conductivity of the grid is detected, the conductivity of the produced grid is found to be inferior to that of the grid produced in the test. Finally, through continuous experiments, the reason is found to be that: the composite wires used in the actual production process are longer, because of the shortage of production fields, the composite wires are produced firstly and then conveyed to a grid weaving workshop for weaving, and the composite wires are abraded in the conveying process. During the test, the used composite wires are short, and workers in charge of weaving directly move the produced composite wires to a weaving workshop, so that the composite wires are not worn without passing through a conveying mechanism, and the conductivity of the grid formed by weaving the worn composite wires is poor.
However, in actual production, the composite wire needs to be conveyed, so a conveying mechanism is required, the abrasion generated when the conveying mechanism is in contact with the composite wire can be reduced as much as possible, but the abrasion is difficult to eliminate all the time, and the conductivity of the grid actually produced cannot completely reach the effect in the test all the time. Finally, through repeated tests, a material supplementing step is added before weaving, and material supplementing is carried out at the worn part of the composite wire.
When the line is cut in the step (four), the core material which is not coated with the metal or the metal alloy initially cannot be used for manufacturing the grid, so that the grid needs to be cut off.
The beneficial effect of this scheme does: the composite wire formed finally is in a triangular prism shape, and under the condition that the volume, the length and the bottom area are the same, the surface area of the triangular prism is larger than that of the cylinder, so that the contact area between the unit length and the active substance is the largest, and the active substance can be effectively prevented from falling off from the woven grid.
The edges and corners of the triangular prism-shaped composite wires are easy to wear, and the metal or metal alloy on the surface of the composite wires plays a role in electric conduction, so that the electric conductivity of the finally woven grid is reduced after the composite wires are worn; in the scheme, before weaving, the core material and metal or metal alloy do not form the composite wire, the cylindrical core material is convenient to transport and store, the core material has no edges and corners and is not easy to wear, and the composite wire is woven after being processed, so that the wear of the composite wire can be reduced.
And thirdly, after the composite wires are formed before weaving, supplementing materials again before use, and filling the worn part of the limiting seat in the moving process, so that the wear on the composite wires for weaving is further reduced, and the reduction of the conductivity of the grid is avoided.
And (IV) the blockage of the discharge pipe, the feed pipe, the material supplementing pipe, the coating channel and the material supplementing channel can be avoided, so that the coating mechanism and the material supplementing mechanism can be normally used when the grid is woven next time.
And (V) clamping the two corners of the composite wire into the supporting mechanism in the conveying process, wherein the composite wire cannot rotate relative to the supporting mechanism, and finally the worn part of the composite wire is the contact part of the composite wire and the supporting mechanism, so that the worn part of the composite wire in the moving process is convenient to determine, and the material supplementing is convenient.
Preferably, in the first scheme, as a further improvement on the basic scheme, the speed of pulling the core material in the third step is 2-5 cm/s. The phenomenon that the movement speed of the core material relative to the coating channel is too high is avoided, enough time is ensured to enable the molten metal or the metal alloy to enter the coating channel from the feeding pipe, and finally the triangular prism-shaped composite line is formed. Secondly, under the condition that the length of the cooling water pipe is not changed, the composite wire can not be completely solidified due to the excessively high moving speed relative to the coating channel, so that the cooling time of the composite wire is shortened, and the composite wire is easy to deform during moving and weaving.
In a second preferred embodiment, as a further improvement of the first preferred embodiment, the length of the weft is 2-2.5 times of the length of the warp. The grid can be formed into a polar plate after being processed in a series of ways and then cut, the horizontal battery adopts the bipolar plate, and the length of the bipolar plate is greater than the width, so that the length of the grid is greater than the width when being woven, and the waste of the grid can be reduced when being cut.
Preferably, in the third aspect, as a further improvement of the second aspect, the distance between the warp threads is 1-2 mm. Gaps are reserved on the grid, so that active substances can be conveniently smeared to form the polar plate.
And (4) preferably, as a further improvement on the preferred scheme, in the step (five), before the first weaving, cold air is used for cooling the warps and the wefts. The cold air further reduces the temperature of the composite thread, and the composite thread is prevented from scalding workers.
Preferably, in the fifth step, as a further improvement to the fourth step, in the step (fifth), the clamping device is used to clamp one end of the warp yarn in the first weaving in the step (fifth). Warp swaying during weaving can be avoided when clamping device presss from both sides tight warp.
Preferably, in a sixth aspect, as a further improvement of the fifth aspect, after the second weaving in the sixth aspect, the warp threads attached to the clamping device are cut off. The composite wire is easy to deform when the clamping device clamps the warp, and the conductivity of the composite wire can be prevented from being reduced by cutting the deformed composite wire.
Preferably, the core material is glass fiber as a further improvement of the preferred embodiment. The glass limit density is small, and the weight of the finally manufactured grid can be reduced by adopting the glass fiber under the condition of the same volume.
