Description

Technical Field

[0001] This invention belongs to the technical field of battery production and processing, specifically, it relates to a battery plate production line. Background Technology

[0002] Current battery plate production mainly includes gravity casting and mesh casting. The main drawbacks of gravity casting are: it involves pouring molten lead into a grid mold, resulting in a long solidification time and a long production cycle, making it difficult to meet the demands of large-scale, rapid production; furthermore, this process is not suitable for producing thinner grids, limiting product specifications and performance improvements, and impacting production efficiency. Many steps in gravity casting require manual operation, such as pouring molten lead and opening and closing the mold, which not only increases labor costs but also increases the risk of human error, affecting product quality stability. Moreover, the high-temperature casting process generates a large amount of lead fumes containing lead and other harmful substances, which, if not effectively treated, will seriously harm the environment and the health of operators. Additionally, gravity casting produces a significant amount of waste lead slag, with lead loss ranging from 15% to 20%. This waste lead slag requires recycling and special treatment, increasing production costs and environmental governance pressure. During gravity casting, the solidification process of molten lead in the mold is affected by various factors, such as mold temperature, molten lead temperature, and casting speed. This can easily lead to uneven grid thickness, porosity, inclusions, and other defects, thus affecting battery performance and lifespan. The main drawbacks of the mesh-forming production method are: mesh-forming involves continuous rolling and cutting on rolled lead strips, stretching them left and right into a mesh shape. This method is time-consuming to process the tabs, and the grid structure is limited, failing to meet the production requirements of some special grid structures. Mesh-formed grids have a relatively loose surface structure, resulting in poorer adhesion of active materials compared to other production methods. This can lead to active materials easily detaching during battery charging and discharging, affecting battery capacity and cycle life. Because mesh-formed grids are formed by stretching lead strips, their internal structure has a certain directionality, resulting in relatively low mechanical strength. During battery use, problems such as grid deformation and breakage can easily occur, affecting battery reliability. Furthermore, the edges of the lead strip often need to be trimmed during the mesh-forming process, leading to material waste and increased production costs. Summary of the Invention

[0003] This invention provides a battery plate production line to improve production efficiency, reduce energy consumption and lead loss, make the plate grains uniform, have stable strength and good adhesion of active materials, while significantly reducing lead fume and solid waste emissions, making it easier to integrate with intelligent production, and comprehensively solving the pain points of efficiency, cost, quality and environmental protection of non-continuous casting processes.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A battery plate production line includes a continuous casting roll, a multi-stage casting mechanism, a plate immersion mechanism, an adjustable transition mechanism, a steering mechanism, and a winding mechanism arranged sequentially along the processing direction of the plate strip. A transmission wheel is coaxially mounted at one end of the continuous casting roll, and an adjustment frame is installed between the continuous casting roll and the multi-stage casting mechanism.

[0005] Furthermore, adapter seats are rotatably connected to both ends of the continuous casting roll. An angle adjustment mechanism is installed between one of the adapter seats, the adjusting frame, and the continuous casting roll. The angle adjustment mechanism includes a drive motor installed on one of the adapter seats, a drive gear coaxially mounted on the output shaft of the drive motor, and a driven gear mounted on the adjusting frame at the connection point between the adjusting frame and the continuous casting roll. The drive gear and the driven gear mesh with each other.

[0006] 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. An assembly seat is rotatably connected to each axial end of the continuous casting roll. A radial drive component extending radially along the continuous casting roll is installed between the assembly seat and the corresponding transition arm.

[0007] 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.

[0008] Furthermore, the electrode plate immersion mechanism includes an immersion tank with its upper end in an open state. Multiple first drive rollers are spaced apart in the immersion tank along the conveying direction of the electrode plate belt. A second drive roller is respectively arranged above the first drive rollers located at both ends of the multiple first drive rollers. Each first drive roller and each second drive roller is submerged below the liquid surface of the immersion tank. An inlet roller and an outlet roller are rotatably connected to both ends of the upper end face of the immersion tank.

[0009] Furthermore, the adjustable transition mechanism includes a base with a first vertical drive member connected to its lower end, a roller seat connected to the base, and multiple transition rollers rotatably connected to the roller seat along the conveying direction of the electrode belt. The electrode belt passes through each transition roller in a serpentine pattern.

[0010] Furthermore, an adjusting roller is provided on the roller seat and between two adjacent transition rollers therein. Sliding blocks are rotatably connected to both ends of the adjusting roller. Vertically extending sliding channels are symmetrically opened on both sides of the roller seat. Each sliding block is slidably assembled at the corresponding sliding channel. A second vertical driving member is installed between the roller seat and each sliding block.

[0011] Furthermore, the steering mechanism includes a longitudinal mounting rod extending along the conveying direction of the electrode belt, with support plates installed at both ends of the longitudinal mounting rod, and multiple roller steering assemblies installed on the longitudinal mounting rod and between the two support plates. The multiple roller steering assemblies are spaced apart along the length of the longitudinal mounting rod, and the angle between these roller steering assemblies and the horizontal plane gradually changes from a parallel state to a perpendicular state.

[0012] Furthermore, the roller steering assembly includes a clamping seat that is detachably clamped on a longitudinal mounting rod. A first arm is constructed on the clamping seat. The first arm is connected to a fixed seat via a second arm. Both ends of the second arm are connected to the first arm and the fixed seat respectively by fastening bolts. An assembly roller seat is fixed on the fixed seat. Two opposing steering rollers are rotatably mounted on the assembly roller seat.

[0013] Furthermore, the winding mechanism includes a drive shaft rotatably mounted on the base, a pulley coaxially mounted on the drive shaft, a support disk coaxially fixed to the upper end of the drive shaft, and a winding shaft coaxially connected to the upper end of the support disk. The electrode strip is wound onto the winding shaft to form an electrode roll, and the lower end of the electrode roll contacts the upper surface of the support disk.

[0014] The present invention, by employing the aforementioned structure, achieves the following technological advancements compared to existing technologies: The present invention continuously supplies molten lead to the outer circumference of the continuous casting roll via a multi-stage casting mechanism. Simultaneously, a drive wheel rotates, causing the continuous casting roll to rotate. As the continuous casting roll rotates, the molten lead on its surface cools and solidifies, gradually detaching from the roll to form a continuous electrode strip. After detaching from the roll, the electrode strip passes sequentially through an electrode immersion mechanism, an adjustable transition mechanism, and a steering mechanism, finally being wound onto a winding mechanism. Within the electrode immersion mechanism, the electrode strip is effectively cooled, and a film is coated onto it to protect it. The adjustable transition mechanism forms a buffer zone to cushion the electrode strip, ensuring that the portion of the strip between the immersion mechanism and the adjustable transition mechanism is drooping, preventing the strip from being strained under tension. Furthermore, the operation of the adjustable transition mechanism can be controlled to prevent the electrode strip from excessively drooping and contacting the ground. The steering mechanism is used to turn the electrode strip to facilitate winding by the coiling mechanism. This invention adjusts the thickness of the cast electrode by changing the distance and opening / closing angle between the multi-stage casting mechanism and the continuous casting rolls through the adjustment frame. In summary, this invention effectively improves production efficiency, reduces energy consumption and lead loss, results in uniform electrode grains, stable strength, and good adhesion of active materials, while significantly reducing lead fumes and solid waste emissions. It also facilitates integration with intelligent production, comprehensively addressing the efficiency, cost, quality, and environmental challenges of non-continuous casting processes.

Detailed Implementation

[0018] 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.

[0019] This invention discloses a battery plate production line, such as... Figure 1-19As shown, the system includes a continuous casting roll 100, a multi-stage casting mechanism 400, an electrode immersion mechanism 700, an adjustable transition mechanism 800, a steering mechanism 900, and a winding mechanism 1000 arranged sequentially along the processing direction of the electrode strip 1100. A transmission wheel 300 is coaxially mounted at one end of the continuous casting roll 100, and an adjustment frame 500 is installed between the continuous casting roll 100 and the multi-stage casting mechanism 400. The working principle and advantages of this invention are as follows: This invention continuously supplies molten lead to the outer circumferential surface of the continuous casting roll 100 through a multi-stage casting mechanism 400. At the same time, the drive transmission wheel 300 rotates, causing it to drive the continuous casting roll 100 to rotate. As the continuous casting roll 100 rotates, the molten lead on its surface cools and solidifies, gradually detaching from the continuous casting roll 100, thereby forming a continuous electrode strip 1100. After the electrode strip 1100 detaches from the continuous casting roll 100, it passes through the electrode immersion mechanism 700, the adjustable transition mechanism 800, and the turning mechanism 900 in sequence, and is finally wound onto the winding mechanism 1000. Within the electrode immersion mechanism 700, the electrode strip 1100 is effectively cooled, and a film is coated onto it to protect it. The adjustable transition mechanism 800 forms a buffer zone to cushion the electrode strip 1100, ensuring that the portion of the electrode strip 1100 between the electrode immersion mechanism 700 and the adjustable transition mechanism 800 is in a drooping state, preventing it from being strained under tension. Furthermore, the adjustable transition mechanism 800 can be controlled to prevent the electrode strip 1100 from drooping excessively and contacting the ground. The steering mechanism 900 is used to turn the electrode strip 1100 to facilitate winding by the winding mechanism 1000. This invention adjusts the thickness of the cast electrode by changing the distance and opening / closing angle between the multi-stage casting mechanism 400 and the continuous casting roller 100 through the adjustment frame 500. In summary, this invention can effectively improve production efficiency, reduce energy consumption and lead loss, make the electrode plate have uniform grains, stable strength and good adhesion of active materials, while significantly reducing the emission of lead fumes and solid waste, making it easier to integrate with intelligent production, and comprehensively solving the pain points of efficiency, cost, quality and environmental protection in non-continuous casting processes.

[0020] As a preferred embodiment of the present invention, such as Figure 2-13As shown, adapter seats 200 are rotatably connected to both ends of the continuous casting roll 100 along its axial direction. A transmission wheel 300 is coaxially mounted on one end of the continuous casting roll 100 along its axial direction. A multi-stage casting mechanism 400 is located on one circumferential side of the continuous casting roll 100. An adjusting frame 500 is installed between the continuous casting roll 100 and the multi-stage casting mechanism 400. An 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 embodiment are: by adjusting the adjusting frame 500, the distance and opening / closing angle between the multi-stage casting mechanism 400 and the continuous casting roll 100 are changed, thereby adjusting the thickness of the cast electrode plate. In this embodiment, the angle adjustment mechanism 600 is controlled to cause the adjustment frame 500 to drive the multi-stage casting mechanism 400 to rotate at a certain angle along the axis of the continuous casting roller 100, thereby adjusting the continuous casting starting point of the electrode plate strip 1100. This ensures that when producing electrode plates of corresponding thickness, the electrode plates are in a fully solidified state when they leave the continuous casting roller 100. In summary, among the various manufacturing processes for battery electrode plates, continuous casting is increasingly widely used in large-scale production due to its high production efficiency, uniform electrode plate structure, and stable performance. The ability to freely adjust the electrode plate thickness during continuous casting directly determines the flexibility and practicality of the process. Freely adjusting the electrode plate thickness not only solves various defects caused by fixed thickness but also creates significant value for enterprises from multiple dimensions such as 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 (such as lead alloys) are prone to slight fluctuations during continuous casting. If the electrode plate thickness is fixed, these fluctuations may lead to abnormal electrode plate quality. For example, when the lead alloy melt temperature is slightly low and its fluidity decreases, a fixed-thickness electrode plate is prone to defects such as surface depressions and internal shrinkage cavities; while when the melt temperature is too high, it may lead to excessive electrode 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, when the melt fluidity is poor, the electrode plate thickness can be appropriately reduced to ensure that the melt fully fills the mold; when the melt fluidity is too strong, the thickness can be appropriately 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.

[0021] As a preferred embodiment of the present invention, such as Figure 4As 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 1100 are produced synchronously, and adjacent electrode strips 1100 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 1100 on adjacent electrode plates to obtain the required electrode plates.

[0022] As a preferred embodiment of the present invention, such as Figure 5-8As 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.

[0023] As a preferred embodiment of the present invention, such as Figure 9 , 10As shown in Figure 12, 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 a 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.

[0024] As a preferred embodiment of the present invention, such as Figure 11As 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. A driven gear 603 is mounted on the adjustment frame 500 at its connection with the continuous casting roll 100, i.e., the driven gear 603 is mounted on a corresponding mounting seat 504. 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 1100 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.

[0025] As a preferred embodiment of the present invention, such as Figure 13 , 14 As shown, the electrode plate immersion mechanism 700 includes an immersion tank 701, the upper end of which is open. Multiple first drive rollers 704 are spaced apart in the immersion tank 701 along the conveying direction of the electrode plate belt 1100. Second drive rollers 705 are respectively arranged above the first drive rollers 704 located at both ends. Each first drive roller 704 and each second drive roller 705 are immersed below the liquid surface of the immersion tank 701. An inlet roller 702 and an outlet roller 703 are rotatably connected to both ends of the upper end face of the immersion tank 701. The working principle and advantages of this embodiment are as follows: the electrode strip 1100 enters the immersion tank 701 through the guide roller 702, and then passes through each of the first drive rollers 704 in sequence. Moreover, due to the restriction of the two second drive rollers 705, the electrode strip 1100 is always immersed in the liquid in the immersion tank 701 during the process of passing through the immersion tank 701, thereby cleaning, cooling and covering the electrode strip 1100 with a liquid film. Then, the electrode strip 1100 is smoothly discharged from the immersion tank 701 by the discharge roller 703. This embodiment allows for continuous replacement of the liquid within the immersion tank 701. Specifically, a first liquid pipe and a second liquid pipe are installed on the immersion tank 701. An external tank is located outside the immersion tank 701, with a filter connected to its inlet. The inlet of the external tank is connected to the filter via a pressure pump. The inlet of the pressure pump is connected to the first liquid pipe on the immersion tank 701, and the second liquid pipe is connected to the outlet of the external tank. The external tank is placed within a cooling chamber, thereby ensuring that the heat dissipated from the electrode strip 1100 is effectively carried away.

[0026] As a preferred embodiment of the present invention, such as Figure 15 , 16As shown, the adjustable transition mechanism 800 includes a base 801, a roller seat 803, and multiple transition rollers 805. Two first vertical drive members 802 are symmetrically arranged at the lower end of the base 801, with the lower end of each first vertical drive member 802 fixedly mounted on the ground. The roller seat 803 is fixedly connected to the upper end of the base 801, and the multiple transition rollers 805 are rotatably connected to the roller seat 803. These transition rollers 805 are spaced apart along the conveying direction of the electrode belt 1100, and the electrode belt 1100 passes through each transition roller 805 in a serpentine pattern. In this embodiment, the electrode belt 1100 passes through each transition roller 805 in a serpentine pattern, thereby improving the stability of the electrode belt 1100 as it passes through the adjustable transition mechanism 800 and preventing the electrode belt 1100 from being over-tensioned or over-slack. Furthermore, the tension of the electrode belt 1100 can be adjusted by increasing or decreasing the number of transition rollers 805, thus preventing damage caused by over-tension. When the distance between the part of the electrode belt 1100 located between the electrode immersion mechanism 700 and the adjustable transition mechanism 800 and the ground exceeds a predetermined range—that is, when that part of the electrode belt 1100 sags to the ground or becomes tense—the two first vertical drive members 802 are controlled to move synchronously, causing the base 801 to move vertically. The base 801 then drives the roller seat 803 to move synchronously, thus adjusting the sag of the electrode belt 1100. This embodiment can adjust the tension and length of the electrode strip 1100 at the adjustable transition mechanism 800, thereby improving the stability of the electrode strip 1100 as it passes through the adjustable transition mechanism 800 and ensuring that the tension of the electrode strip 1100 remains within a predetermined range. The measures taken are as follows: an adjusting roller 806 is provided on the roller seat 803 and between two adjacent transition rollers 805 located therein; sliding blocks 807 are rotatably connected to both ends of the adjusting roller 806; vertically extending sliding channels 804 are symmetrically opened on both sides of the roller seat 803; each sliding block 807 is slidably assembled at the corresponding sliding channel 804; and a second vertical driving member 808 is installed between the roller seat 803 and each sliding block 807. In this embodiment, by controlling the synchronous operation of two second vertical drive members 808, the adjusting roller 806 moves vertically, thereby adjusting the serpentine shape of the electrode strip 1100. This changes the length of the electrode strip 1100 passing through the adjustable transition mechanism 800, and the force between the electrode strip 1100 and the adjusting roller 806 also changes accordingly. In this embodiment, the first vertical drive member 802 and the second vertical drive member 808 can be hydraulic cylinders or pneumatic cylinders. This embodiment can also finely adjust the sag of the electrode strip 1100 located between the electrode immersion mechanism 700 and the adjustable transition mechanism 800 by controlling the operation of the second vertical drive member 808.

[0027] As a preferred embodiment of the present invention, such as Figure 17 , 18 As shown, the steering mechanism 900 includes a longitudinal mounting rod 901 and multiple roller steering assemblies 903. The longitudinal mounting rod 901 extends along the conveying direction of the electrode belt 1100, and support plates 902 are mounted at both ends of the longitudinal mounting rod 901, with the lower end of each support plate 902 fixedly connected to the ground. The multiple roller steering assemblies 903 are all mounted on the longitudinal mounting rod 901, located between two support plates 902, and spaced apart along the length of the longitudinal mounting rod 901. The orientations of these roller steering assemblies 903 are all different, with their tilt angles changing progressively; that is, the angle between these roller steering assemblies 903 and the horizontal plane gradually changes from parallel to perpendicular. Thus, the electrode strip 1100, which originates from the adjustable transition mechanism 800, enters the steering mechanism 900 in a horizontal position. Then, under the action of these roller steering assemblies 903, it gradually turns and converts to a vertical state, facilitating the winding mechanism 1000 to wind up the electrode strip 1100. In this embodiment, the roller steering assembly 903 includes a clamping seat 9031, a first arm 9032, a second arm 9033, a fixing seat 9034, an assembly roller seat 9035, and two steering rollers 9036. The clamping seat 9031 is detachably clamped onto the longitudinal mounting rod 901, and the overall posture of the roller steering assembly 903 can be adjusted by adjusting the angle at which the clamping seat 9031 is clamped onto the longitudinal mounting rod 901. The first arm 9032 is mounted on the clamping seat 9031. The first arm 9032 is connected to the fixed seat 9034 via the second arm 9033. Both ends of the second arm 9033 are connected to the first arm 9032 and the fixed seat 9034 respectively via fastening bolts. By adjusting the angle of the connection between the first arm 9032, the second arm 9033, and the fixed seat 9034, the angle and extension (distance from the longitudinal mounting rod 901) of the assembly roller seat 9035 are adjusted, thereby ensuring that the electrode plate belt 1100 can pass through stably and smoothly. In this embodiment, the assembly roller seat 9035 is fixedly mounted on the fixed seat 9034. Two guide rollers 9036 are symmetrically arranged and rotatably mounted on the assembly roller seat 9035. The electrode plate belt 1100 passes through the gap between these two guide rollers 9036.

[0028] As a preferred embodiment of the present invention, such as Figure 19As shown, the winding mechanism 1000 includes a base 1001, a drive shaft 1002, a support plate 1004, and a winding shaft 1005. The drive shaft 1002 is rotatably mounted on the base 1001, which is fixedly mounted on the ground. A pulley 1003 is coaxially mounted on the drive shaft 1002. In this embodiment, the support plate 1004 is fixedly connected to the upper end of the drive shaft 1002, and their axes coincide. The winding shaft 1005 is coaxially connected to the upper end of the support plate 1004. The electrode strip 1100 is wound onto the winding shaft 1005 to form an electrode roll, the lower end of which contacts the upper surface of the support plate 1004. In this embodiment, the drive pulley 1003 rotates, causing the support plate 1004 and the winding shaft 1005 to rotate, thereby achieving the winding operation of the electrode strip 1100.
