Description

Electroplate lead net grid of carbon fiber

Technical Field

The utility model relates to a grid and the manufacturing method of lead accumulator, especially relate to a low in manufacturing cost, simple process, production efficiency is high, the electric conductive good electroplating carbon fiber lead net grid.

Background

The lead accumulator is widely used in the fields of automobile starting power supply, uninterrupted power supply, power supply and energy storage power supply from electric bicycle to diesel submarine, etc. because of its advantages of stability, reliability, no memory effect, low cost, capacity of being made into single large-capacity battery, etc., its output and energy storage amount are still the first of chemical power supply. The grid of the traditional lead storage battery has three preparation methods: firstly, gravity casting is carried out, and the method has wide application range, low efficiency and high pollution; the grid is punched, the method is to prefabricate the lead belt first and then punch and process, its advantage is high in efficiency, but will produce 70-80% blanking while punching, the energy consumption is high, and can only make the sheet bar below 1.2 mm; and thirdly, continuous casting and rolling, the method has the advantages of high efficiency and low energy consumption, but the grid is not corrosion-resistant and can only be used for manufacturing a thin grid with the thickness of less than 1.5 mm. Therefore, people gradually develop lead mesh grids as an alternative, namely glass fiber composite lead wires are woven to form meshes, so that lead wires with different wire diameters can be manufactured according to actual requirements, theoretically, lead meshes with any thickness can be woven to be used as battery grids, and the lead mesh grids are light in weight, corrosion resistant and free of lead dust pollution, for example, the technical scheme disclosed in patent CN 102751507A.

For lead mesh grids, there are currently two different manufacturing methods of weaving by shuttleless looms and weaving by shuttleless looms. The action process of weaving the lead net by adopting a shuttle loom comprises the following steps: 1. the warps are regularly opened and closed, and when the warps are opened, the weft shaft winding the wefts is pulled by the shuttle box to pass through the first warp to the last warp in the opening area in the forward direction, and a semi-circular arc is formed at the first warp; 2. The beating-up mechanism pushes the weft to the root of the opened angle of the warp, the warp is closed to clamp the weft, meanwhile, the net moves a weft interval required by design along the warp direction, and the weft in the shuttle box is reversed; 3. the warp threads continue to move in the vertical direction and are opened again, the shuttle box reversely passes through the last warp thread in the opening area to the first warp thread, and a semicircular arc is formed at the last warp thread; 4. the beating-up mechanism pushes the weft to the root of the opened angle of the warp, the warp is closed to clamp the weft, and the net moves along the warp direction by a weft interval required by design; 5. and (4) repeating the steps 1 to 4 until the weft thread in the shuttle box is used up, and replacing a new weft thread shaft. The lead net obtained by the weaving method of the shuttle loom has the advantages that the weight of the composite lead wires is heavy, the adhesive force between the lead wires is large, the length of weft threads capable of being wound in a shuttle box is very limited, the shuttle needs to be frequently replaced, the efficiency is extremely low, and the waste caused by the residual weft threads of the shuttle is not small each time. And the action process of weaving the lead net by adopting the shuttleless loom is as follows: 1. the warp threads are regularly opened and closed, when the warp threads are opened, the weft threads are pulled to a rapier head cross connection area in the middle in a forward direction by the thread feeding rapier and are retained, meanwhile, the receiving rapier also moves in a reverse direction to the rapier head cross connection area, and after the rapier head of the receiving rapier clamps the weft threads, the rapier head of the thread feeding rapier looses the weft threads; 2. the thread feeding rapier and the connecting rapier move reversely, exit from the connecting area and return to the original position, and the beating-up mechanism pushes the weft thread to the root of the opening angle of the warp thread; 3. the rapier head of the receiving rapier looses the weft, the warp is closed to clamp the weft, and the weft is cut off at the same time; 4. the net moves along the warp direction by a weft distance required by design; 5. and (5) the warp continues to move in the original direction, the warp is opened again, the weft is clamped again by the thread feeding rapier, and the steps 1 to 4 are repeated. The weft shaft of the method does not need to pass through a warp area, theoretically, the length of the weft shaft can be infinite, the number of times of intermediate weft changing pause is small, and the efficiency is high.

However, in the above prior art, both the shuttle loom and the shuttleless loom are single weft weaving methods (for example, the warps and the wefts have the same fineness, or the warps and the wefts have the same fineness), and the lead mesh grid manufactured by the method has the following defects: 1. the warps and the wefts are made of lead wires, so that the lead consumption is large and the cost is high; 2. the grid has no frame, so that the expansion of active substances cannot be limited in the charging and discharging processes of the battery, the contact short circuit of positive and negative active substances and the softening and falling of the positive active substance are easy to occur, and the service life of the battery is reduced; 3. the grid has no pole lug, the bus bar needs to be prefabricated, and then the grid is welded with the weft lead wire to form the pole lug, the process is complex, and the production efficiency is low.
