Description

Technical Field

[0001] This invention belongs to the technical field of battery production and processing, specifically, it relates to a continuous casting equipment for battery plates. Background Technology

[0002] As an energy storage device that converts chemical energy into electrical energy, the battery plays an irreplaceable role in many fields such as automobiles, communications, power, and new energy. The electrode plates, as the core component of the battery, directly determine its performance, lifespan, and safety based on their processing quality. Thickness adjustment is a critical process step in electrode plate manufacturing. If the electrode plate thickness cannot be adjusted, it will trigger a series of chain reactions, leading to various serious defects and causing significant negative impacts on battery production, use, and market application.

[0003] In terms of energy storage capacity, a battery's capacity primarily depends on the quantity and utilization rate of active materials on its plates. If the plates are too thick (fixed due to lack of adjustment), while theoretically more active materials can be accommodated, the internal current path becomes longer, increasing current resistance and preventing the active materials from fully participating in the electrochemical reaction. Especially under high-current discharge scenarios, the deep-layered active materials on the plates struggle to respond quickly, resulting in an actual energy storage capacity far below design expectations. Conversely, if the plates are too thin (fixed due to lack of adjustment), the total amount of active materials is insufficient, directly limiting the battery's energy storage capacity and significantly reducing its range, failing to meet the normal operating requirements of equipment. For example, in automotive starter batteries, if the plates are too thin and the energy storage capacity is insufficient, starting the car will be difficult or even impossible. In backup batteries for communication base stations, insufficient energy storage capacity will prevent them from providing sufficient power for the base station during power outages, affecting the stability of the communication network.

[0004] In terms of charge and discharge performance, the inability to adjust the plate thickness leads to low charging and discharging efficiency and poor stability. During charging, if the plates are too thick, the electrolyte penetrates into the plates more slowly, causing the active materials on the surface to complete the charging reaction first, while the internal active materials remain in an incompletely charged state, easily resulting in "undercharging." Simultaneously, excessively thick plates also make it difficult to dissipate heat generated during charging quickly, leading to localized overheating and plate polarization, further reducing charging efficiency. During discharging, as mentioned earlier, excessively thick plates increase current resistance, causing the discharge voltage to drop too quickly and making it impossible to maintain stable discharge output. Conversely, excessively thin plates, due to the limited total amount of active material, result in a short discharge time and are prone to deformation during discharge, affecting discharge stability. Furthermore, inconsistent plate thickness also leads to performance differences among individual cells within the battery. During charge and discharge cycles, the lower-performing cells will reach their charge and discharge limits first, thus affecting the overall charge and discharge performance of the battery pack, creating a "bottleneck effect."

[0005] In terms of lifespan, the inability to adjust the plate thickness accelerates battery aging and significantly shortens its lifespan. On one hand, if the plates are too thick, the active material inside the plates will generate more heat due to current resistance and polarization during charge-discharge cycles. Prolonged exposure to high temperatures will accelerate corrosion of the plate's grid structure, and the active material is prone to shedding and softening, leading to a gradual decline in plate performance. On the other hand, if the plates are too thin, their mechanical strength is low. During charge-discharge cycles, the plates will frequently deform due to volume changes (expansion during charging and contraction during discharging), easily leading to plate bending, breakage, and other malfunctions. This can cause serious problems such as internal short circuits and leakage, directly resulting in battery failure. Related experimental data shows that when the plate thickness deviation exceeds 5% of the standard value, the battery's lifespan will be shortened by more than 30%; if the thickness deviation exceeds 10%, the lifespan can be shortened by as much as 50%, which has a significant impact on the battery's economy and reliability. Summary of the Invention

[0006] This invention provides a continuous casting equipment for battery plates to solve the problem of the inability to adjust the thickness of the plates during processing, thereby enabling the produced battery products to have high quality, high performance, and high safety, reducing enterprise costs, improving market competitiveness, and promoting the healthy and sustainable development of the battery industry.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A continuous casting equipment for battery plates includes a continuous casting roll with a transfer seat rotatably connected to both ends of the axial direction, a transmission wheel coaxially mounted at one end of the continuous casting roll, a multi-stage casting mechanism provided on one side of the continuous casting roll in the circumferential direction, an adjustment frame installed between the continuous casting roll and the multi-stage casting mechanism, and an angle adjustment mechanism installed between one of the transfer seats, the adjustment frame and the continuous casting roll.

[0008] Furthermore, the continuous casting roll includes a roll-shaped body, with connecting shafts coaxially fixed at both ends of the roll-shaped body. Each connecting shaft is rotatably connected to a corresponding adapter seat. Multiple electrode casting groove groups are constructed at intervals along the axial direction on the outer circumferential surface of the roll-shaped body, and adjacent electrode casting groove groups are interconnected through connecting grooves.

[0009] Furthermore, the multi-stage casting mechanism includes a casting body extending axially along the continuous casting roll to both ends of the continuous casting roll. Multiple cavities are constructed within the casting body at intervals along its height. Multiple casting ports are opened at one end of the casting body near the continuous casting roll. Each casting port is connected to a corresponding cavity. Molten lead enters at least one cavity and is cast onto the outer circumferential surface of the continuous casting roll through the corresponding casting port.

[0010] Furthermore, the casting body has an assembly cavity with its open end facing away from the continuous casting roll. Multiple partition plates are fixed at intervals along the height direction of the casting body within the assembly cavity. The multiple cavities are formed by the multiple partition plates separating the assembly cavities. A connecting cover is detachably connected to one end of the casting body facing away from the continuous casting roll.

[0011] Furthermore, each of the aforementioned chambers is fitted with a liquid inlet pipe. The casting port extends along the axial direction of the continuous casting roll to both ends of the casting body. The liquid inlet pipe extends from one end of the casting port along the axial direction of the continuous casting roll to the other end of the casting port. Multiple liquid outlet holes are provided at intervals along the length direction of the liquid inlet pipe at one end near the casting port. A control valve is installed on the liquid inlet pipe.

[0012] Furthermore, a plurality of vent holes are provided at one end of the casting body near the continuous casting roll and at the upper part of each casting port, and the plurality of vent holes are spaced apart along the length direction of the casting port.

[0013] Furthermore, the adjusting frame includes a connecting arm disposed on one circumferential side of the continuous casting roll. The connecting arm extends axially along the continuous casting roll to both ends of the continuous casting roll. A transition arm is connected to each end of the connecting arm. Each transition arm is rotatably connected to the corresponding axial end of the continuous casting roll. The connecting arm is connected to the multi-stage casting mechanism via an angle adjusting component. The lower part of each side of the multi-stage casting mechanism is pivotally connected to the corresponding transition arm.

[0014] Furthermore, a mounting base is rotatably connected to each axial end of the continuous casting roll, and a radial drive component extending radially along the continuous casting roll is installed between the mounting base and the corresponding adapter arm.

[0015] Furthermore, the angle adjustment mechanism includes a drive motor mounted on one of the adapters, a drive gear coaxially mounted on the output shaft of the drive motor, and a driven gear mounted on the adjustment frame at the connection point between the adjustment frame and the continuous casting roll, wherein the drive gear and the driven gear mesh with each other.

[0016] The present invention, by employing the aforementioned structure, achieves the following technological advancements compared to existing technologies: The present invention drives a transmission wheel to rotate, which in turn rotates the continuous casting roll. During the rotation of the continuous casting roll, molten lead is poured onto the circumference of the roll through a multi-stage casting mechanism. As the roll rotates, the molten lead on its surface cools and solidifies, gradually detaching from the roll to form a continuous electrode strip, facilitating the winding and subsequent slitting of the electrode strip. The present invention adjusts the thickness of the cast electrode strip by changing the distance and opening / closing angle between the multi-stage casting mechanism and the continuous casting roll through an adjusting frame. Furthermore, the present invention controls the angle adjustment mechanism to rotate the multi-stage casting mechanism along the axis of the continuous casting roll by a certain angle, thereby adjusting the starting point of the continuous casting of the electrode strip and ensuring that the electrode strip is fully solidified when it detaches from the roll when producing electrode strips of corresponding thicknesses. In summary, among the various manufacturing processes for battery plates, continuous casting is increasingly widely used in large-scale production due to its high production efficiency, uniform plate structure, and stable performance. The flexibility and practicality of the continuous casting process are directly determined by the ability to freely adjust the plate thickness. Adjusting the plate thickness not only solves various defects associated with fixed thicknesses but also creates significant value for enterprises in multiple dimensions, including production, performance, cost, safety, and market adaptability, becoming a key factor in enhancing the competitiveness of battery products. Furthermore, regarding ensuring the stability of the continuous casting process, parameters such as the composition, temperature, and fluidity of raw materials (e.g., lead alloys) are prone to slight fluctuations during continuous casting. If the plate thickness is fixed, these fluctuations may lead to abnormal plate quality. For example, when the lead alloy melt temperature is slightly low and its fluidity decreases, plates with a fixed thickness are prone to defects such as surface depressions and internal shrinkage cavities; while when the melt temperature is too high, it may lead to excessive plate thickness and insufficient density. If the electrode plate thickness can be freely adjusted, operators can dynamically fine-tune the thickness parameters according to the actual state of the melt: for example, if the melt has poor fluidity, the electrode plate thickness can be appropriately reduced to ensure that the melt fully fills the mold; if the melt has excessive fluidity, the thickness can be moderately increased to avoid dimensional deviations in the electrode plate due to excessive melt flow. This dynamic adjustment capability effectively offsets the impact of raw material fluctuations on production, ensures the stability of the continuous casting process, reduces defective products caused by process fluctuations, and improves production efficiency and product qualification rate. In terms of precise matching of energy storage capacity, freely adjustable thickness allows the "quantity" and "utilization rate" of the active material in the electrode plate to achieve the optimal balance.For energy storage batteries requiring high capacity, adjusting the plate thickness to a thicker specification (e.g., 2.5-3mm) through continuous casting allows for the inclusion of more lead paste active material per unit area, directly increasing the battery's rated capacity and meeting long-term energy storage needs (e.g., home energy storage systems requiring continuous power supply for over 10 hours). For portable devices where size and weight are critical (e.g., emergency lighting equipment), the plate thickness can be reduced to 1-1.5mm, significantly reducing battery size and weight while maintaining basic energy storage capacity, thus improving device portability. More importantly, the continuity of the continuous casting process ensures uniform plate density after thickness adjustment. Compared to other processes, the rolling stage simultaneously optimizes the internal structure of the plates during continuous casting when thickness is freely adjusted, avoiding the problem of "dense outer layer and loose inner layer" in thick plates. This ensures uniform distribution of active material, improves active material utilization, and brings the battery's actual energy storage capacity closer to the design value, reducing performance deviations. In terms of optimizing charge and discharge performance, freely adjustable thickness can specifically address charging and discharging pain points in different scenarios. For scenarios requiring rapid charging and discharging (such as the fast charging needs of new energy vehicles), adjusting the continuous casting electrode plate to a thinner specification can shorten the current transmission path within the electrode plate, reduce internal resistance, and decrease energy loss during charging and discharging. Experimental data shows that, under the same material conditions, a 1.2mm thick continuous casting electrode plate has approximately 30% lower internal resistance than a 2mm thick electrode plate, significantly reduces polarization during fast charging, improves charging efficiency by 15%-20%, and exhibits stronger voltage stability during discharge, avoiding sudden voltage drops due to excessive internal resistance. For scenarios requiring low-rate, long-cycle charging and discharging (such as backup power supplies for communication base stations, typically discharging slowly at a 0.1C rate), a thicker electrode plate can be used. With more active material reserves, the discharge time can be extended. Simultaneously, the thicker electrode plate has stronger structural stability, reducing active material shedding during long-term charge-discharge cycles and further optimizing performance. In the production process, freely adjustable thickness can reduce raw material waste and the cost of defective products. On the one hand, in the continuous casting process, the thickness of the electrode plate is directly related to the amount of lead alloy used. Adjusting the thickness allows companies to precisely control lead alloy consumption according to order requirements. For example, when producing small-capacity batteries, reducing the thickness of the electrode plate can reduce the amount of lead alloy used per plate by approximately 15%-20%. Based on large-scale production (100,000 electrode plates per day), this translates to saving hundreds of kilograms of lead alloy daily, resulting in a significant reduction in raw material costs over the long term. On the other hand, as mentioned earlier, adjusting the thickness can offset the quality risks caused by process fluctuations and reduce defective electrode plates due to thickness abnormalities. Compared to a 10%-15% defect rate with a fixed thickness, adjusting the thickness can reduce the defect rate to below 3%. This not only reduces the waste of resources such as lead alloy and electricity but also eliminates the costs of dismantling and recycling defective electrode plates, reducing environmental protection pressures (such as the cost of harmless treatment of lead slag).

Detailed Implementation

[0020] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0021] This invention discloses a continuous casting equipment for battery plates, such as... Figure 1-11As shown, the system includes a continuous casting roll 100, a transmission wheel 300, a multi-stage casting mechanism 400, an adjusting frame 500, and an angle adjusting mechanism 600. Adapter seats 200 are rotatably connected to both axial ends of the continuous casting roll 100. The transmission wheel 300 is coaxially mounted on one axial end of the continuous casting roll 100. The multi-stage casting mechanism 400 is located on one circumferential side of the continuous casting roll 100. The adjusting frame 500 is installed between the continuous casting roll 100 and the multi-stage casting mechanism 400. The angle adjusting mechanism 600 is installed between the adjusting frame 500, the continuous casting roll 100, and one of the adapter seats 200. The working principle and advantages of this invention are as follows: This invention drives the transmission wheel 300 to rotate, which in turn drives the continuous casting roll 100 to rotate. During the rotation of the continuous casting roll 100, molten lead is poured onto the circumference of the continuous casting roll 100 through the multi-stage casting mechanism 400. As the continuous casting roll 100 rotates, the molten lead on its surface cools and solidifies, gradually detaching from the continuous casting roll 100, thus forming a continuous electrode strip, facilitating the winding and subsequent cutting of the electrode strip. This invention adjusts the thickness of the cast electrode strip by adjusting the adjusting frame 500 to change the distance and opening / closing angle between the multi-stage casting mechanism 400 and the continuous casting roll 100. This invention controls the angle adjusting mechanism 600 to rotate the multi-stage casting mechanism 400 along the axis of the continuous casting roll 100 by a certain angle, thereby adjusting the continuous casting starting point of the electrode strip and ensuring that the electrode strip is fully solidified when it detaches from the continuous casting roll 100 when producing electrode strips of corresponding thicknesses.

[0022] As a preferred embodiment of the present invention, such as Figure 3 As shown, the continuous casting roll 100 includes a roll-shaped body 101, with connecting shafts 102 coaxially fixed at both ends of the roll-shaped body 101. Each connecting shaft 102 is rotatably connected to a corresponding adapter seat 200, and the adapter seat 200 is detachably connected to a corresponding part of the machine body. In this embodiment, multiple electrode casting groove groups 103 are constructed on the outer circumferential surface of the roll-shaped body 101. These electrode casting groove groups 103 are spaced apart along the axial direction of the roll-shaped body 101, and adjacent electrode casting groove groups 103 are interconnected via connecting grooves 104. Molten lead is cast into all the electrode casting groove groups 103 of the continuous casting roll 100 through single-stage or multi-stage casting by the multi-stage casting mechanism 400. As the continuous casting roll 100 rotates, multiple continuous electrode strips are produced synchronously, and adjacent electrode strips are connected by the solidified product of the molten lead cast in the connecting groove 104. During the subsequent cutting of the electrode plates, it is necessary to cut the ribs at the connection between adjacent electrode plates and the ribs at the junction of adjacent electrode plates to obtain the required electrode plates.

[0023] As a preferred embodiment of the present invention, such as Figure 4-7As shown, the multi-stage casting mechanism 400 includes a casting body 401, which extends axially along the continuous casting roll 100 to both ends of the continuous casting roll 100. Multiple sub-cavities 403 are constructed within the casting body 401, and these sub-cavities 403 are spaced apart along the height of the casting body 401. In this embodiment, multiple casting ports 404 are provided at one end of the casting body 401 near the continuous casting roll 100. Each casting port 404 communicates with a corresponding sub-cavity 403, and molten lead enters at least one sub-cavity 403, then is cast onto the outer circumferential surface of the continuous casting roll 100 through the corresponding casting port 404. In this embodiment, the number of casting ports 404 can be increased or decreased as needed to ensure that the thickness of the obtained electrode plate reaches the expected value and to avoid uneven electrode plate thickness. That is, single-stage casting can produce thinner electrode plates, while multi-stage casting produces thicker electrode plates, and multi-stage casting can improve the quality of the electrode plates. In this embodiment, the casting body 401 is divided into sub-cavities 403 by the following means: the casting body 401 has an assembly cavity, the open end of which faces away from the continuous casting roll 100. Multiple partition plates 402 are fixed at intervals along the height direction of the casting body 401 in the assembly cavity. The aforementioned multiple sub-cavities 403 are formed by these partition plates 402 dividing the assembly cavity. A connecting cover 407 is detachably connected to one end of the casting body 401 facing away from the continuous casting roll 100. To ensure an efficient and continuous supply of molten lead and prevent excess molten lead from overflowing from the edge of the casting port 404, this embodiment employs the following measures: an inlet pipe 408 is inserted into each cavity 403. The casting port 404 extends axially along the continuous casting roll 100 to both ends of the casting body 401. The inlet pipe 408 extends axially from one end of the casting port 404 to the other end of the casting port 404. Multiple outlet holes 409 are provided at the end of the inlet pipe 408 near the casting port 404, spaced apart along the length of the inlet pipe 408. A control valve is installed on each inlet pipe 408. Molten lead enters the inlet pipe 408 and continuously flows into the cavity 403 through the outlet holes 409, then is cast onto the continuous casting roll 100 through the casting port 404, thereby ensuring a stable supply of molten lead to the continuous casting roll 100. In this embodiment, to prevent air bubbles in the molten lead from being cast onto the continuous casting roll 100 and affecting the quality of the electrode plate, the following measures are taken: Multiple vent holes 405 are provided at one end of the casting body 401 near the continuous casting roll 100 and above each casting port 404. These vent holes 405 are spaced apart along the length of the casting port 404. In this way, air bubbles first enter the dividing cavity 403 with the molten lead, then separate from the molten lead within the dividing cavity 403, and finally exit through the vent holes 405, ensuring that the cast molten lead is free of gas.

[0024] As a preferred embodiment of the present invention, such as Figure 8 , 9As shown in Figure 11, the adjusting frame 500 includes a connecting arm 501, an angle adjusting component 505, and two transition arms 502. The connecting arm 501 is positioned on one circumferential side of the continuous casting roll 100, extending axially to both ends of the continuous casting roll 100. The two transition arms 502 are respectively connected to both ends of the connecting arm 501. Each transition arm 502 is rotatably connected to the connecting shaft 102 at the corresponding axial end of the continuous casting roll 100. The connecting arm 501 is connected to the multi-stage casting mechanism 400 via the angle adjusting component 505, meaning that both ends of the angle adjusting component 505 are hinged to the connecting arm 501 and the multi-stage casting mechanism 400, respectively. The angle adjusting component 505 is generally selected from electric cylinders, pneumatic cylinders, or hydraulic cylinders. In this embodiment, a pivot shaft 406 is fixed on one side of the casting body 401 of the multi-stage casting mechanism 400. The bottommost liquid inlet pipe 408 coincides with the axis of the pivot shaft 406. The pivot shaft 406 is pivotally connected to one of the adapter arms 502, and the bottommost liquid inlet pipe 408 is pivotally connected to the other adapter arm 502. In this embodiment, by controlling the movement of the tilt adjustment component 505, the multi-stage casting mechanism 400 is rotated by a certain angle along the axis of the pivot shaft 406, thereby adjusting the opening and closing angle between the upper part of the multi-stage casting mechanism 400 and the continuous casting roll 100. In this way, during the casting process, the multi-stage casting mechanism 400 can gradually pour the lead liquid onto the circumference of the continuous casting roll 100 in a progressive manner, ensuring the uniformity of the electrode casting and improving the quality of the electrode. In this embodiment, mounting bases 504 are rotatably connected to each axial end of the continuous casting roll 100. A radial drive component 503 is installed between the mounting base 504 and the corresponding adapter arm 502. The radial drive component 503 extends radially along the continuous casting roll 100, and is preferably an electric cylinder, pneumatic cylinder, or hydraulic cylinder. In this embodiment, by controlling the synchronous movement of the two radial drive components 503, they drive the multi-stage casting mechanism 400 to move closer to or away from the continuous casting roll 100 via the adapter arm 502, connecting arm 501, and tilt adjustment component 505, thereby adjusting the thickness of the casting plate.

[0025] As a preferred embodiment of the present invention, such as Figure 10As shown, the angle adjustment mechanism 600 includes a drive motor 601, which is mounted on one of the adapter seats 200. A drive gear 602 is coaxially mounted on the output shaft of the drive motor 601, and a driven gear 603 is mounted on the adjustment frame 500 at its connection with the continuous casting roll 100. That is, the driven gear 603 is mounted on a corresponding mounting seat 504, and the drive gear 602 and the driven gear 603 mesh with each other. In this embodiment, by controlling the operation of the drive motor 601, it drives the adjustment frame 500 to rotate a predetermined angle along the axis of the continuous casting roll 100 through gear transmission. In this way, the adjustment frame 500 drives the multi-stage casting mechanism 400 to rotate by a corresponding angle, thereby adjusting the continuous casting starting point of the electrode strip and ensuring that when producing electrode strips of corresponding thickness, the electrode strip is in a fully solidified state when it leaves the continuous casting roll 100.
