Description

Technical Field

[0001] This invention relates to the field of storage battery production, and in particular to a storage battery plate curing chamber. Background Technology

[0002] After the battery plates are coated, they need to be placed in a curing chamber for curing. The purpose of this curing is to harden and corrode the lead paste, further oxidizing the free lead in the paste into lead monoxide. Simultaneously, the lead paste and the grid react and bond together, achieving good mechanical strength and electrical performance. Therefore, the quality of plate curing directly affects the overall performance and lifespan of the plates.

[0003] Currently, existing battery plate curing chambers typically involve directly pushing a curing rack with suspended plates into the chamber, where the rack remains stationary. Hot air is usually blown onto the plates from vents on the side wall. This results in plates closer to the vent curing faster than those further away, leading to inconsistent curing speeds. This not only affects curing efficiency and quality but also increases the operating cost of the curing chamber. Therefore, there is an urgent need to research and develop a new battery plate curing chamber to address these issues. Summary of the Invention

Detailed Implementation

[0025] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0026] Example 1: like Figures 1-3As shown, an embodiment of the present invention provides a battery plate curing chamber, including a conventional curing chamber body 1. To achieve automated conveying of the plates within the curing chamber and avoid uneven curing caused by prolonged exposure to wind in a fixed position, a circulating conveying mechanism 2 is horizontally installed on the bottom wall of the curing chamber body 1. The circulating conveying mechanism 2 provides a continuous, closed-loop conveying path, which is the basis for achieving dynamic curing of the plates. To achieve simultaneous curing of multiple batches of plates and fully utilize the internal space of the curing chamber, multiple supporting mechanisms 3 are horizontally connected side by side on the circulating conveying mechanism 2. Each of the multiple supporting mechanisms 3 is vertically connected to a curing rack 4. The supporting mechanism 3, as an intermediate connecting member, can stably connect the curing rack 4 and the circulating conveying mechanism 2, ensuring that the curing rack 4 can move with the circulating conveying mechanism 2. The plates are suspended on the curing rack 4, and the curing rack 4 provides a stable support structure for the plates.

[0027] When it is necessary to cure the battery plates, the coated plates are first hung vertically on the curing rack 4. Then, the curing rack 4 is installed on the circulating conveying mechanism 2 by the bearing mechanism 3. Then, the circulating conveying mechanism 2 is started. The circulating conveying mechanism 2 drives the curing rack 4 to move continuously and slowly along the preset closed-loop path in the curing chamber body 1. Since the curing rack 4 constantly changes its position in the curing chamber body 1, each plate can receive hot air from different directions as evenly as possible, avoiding the problem of over-curing or under-curing of some plates due to fixed position. This ensures that the curing speed of all plates is consistent, significantly improving the curing efficiency and curing quality of the battery plates and reducing the use cost of the curing chamber.

[0028] Among them, such as Figure 2 As shown, to achieve uniform distribution and directional flow of hot air inside the curing chamber, an air supply chamber 101 and an exhaust chamber 102 are respectively provided in the opposite side walls of the curing chamber body 1. The air supply chamber 101 is used to contain and guide the heated fresh air, while the exhaust chamber 102 is used to collect and exhaust the stale air containing moisture. In order to evenly blow the hot air in the air supply chamber 101 into the curing chamber and at the same time evenly draw the internal moisture into the exhaust chamber 102, multiple air inlets 103 and multiple air outlets 104 are respectively arranged side by side on the opposite inner surfaces of the air supply chamber 101 and the exhaust chamber 102. Through the multiple air inlets 103 arranged side by side, hot air can be evenly delivered into the interior of the curing chamber body 1, while through the multiple air outlets 104, internal air can be evenly drawn in, forming a stable horizontal laminar or turbulent airflow field, which is conducive to the rapid discharge of moisture.

[0029] Example 2: Based on Example 1, as follows Figure 4As shown, in order to drive the curing rack 4 to move stably along a closed-loop path, the circulating conveying mechanism 2 includes a pair of drive shafts 201 that are vertically and rotatably connected side by side to the bottom wall of the curing chamber body 1; to achieve synchronous transmission, pulleys 202 are keyed to both drive shafts 201; as the core component of power transmission, the drive shafts 201 need to withstand the tension of the belt 203 and maintain precise rotation; to achieve stepless and smooth power transmission, the two pulleys 202 are connected by a belt 203; the pulleys 202 are used to cooperate with the belt 203 to convert the rotational motion of the drive shafts 201 into the linear motion of the belt 203. The belt 203 is flexible and can wrap around the pulley 202 to form a closed loop, and can support multiple support mechanisms 3. In order to provide a stable power source and precisely control the movement speed of the belt 203, a geared motor 204 is provided on the inner side of the belt 203. The geared motor 204 is vertically bolted to the bottom wall of the curing chamber body 1. The output shaft of the geared motor 204 is connected to the upper end of a drive shaft 201 through a conventional belt reducer in the art. The geared motor 204 can provide large torque and low speed, which is suitable for driving the curing rack 4 fully loaded with electrode plates to move slowly.

[0030] During operation, the geared motor 204 starts, and its output shaft drives the drive shaft 201 connected to it to rotate. The drive shaft 201 drives the pulley 202 on it to rotate. The pulley 202 drives another pulley 202 and the drive shaft 201 to rotate synchronously through the belt 203. The belt 203 circulates under the drive of the pulley 202, thereby driving the supporting mechanism 3 and the curing frame 4 connected to it to move along the preset path, effectively ensuring the curing effect of the electrode plate.

[0031] Among them, such as Figures 4-5As shown, in order to securely connect the curing rack 4 to the belt 203 and allow the curing rack 4 to rotate in a specific position, the supporting mechanism 3 includes a supporting block 301 bolted to the outer surface of the belt 203; the supporting block 301 serves as the base component of the supporting mechanism 3, fixedly connected to the belt 203, and provides an installation base for other components; to facilitate the installation and disassembly of the curing rack 4, arc-shaped strips 302 are horizontally rotatably connected to opposite sides of the supporting block 301; the arc-shaped strips 302 can rotate around their connecting axis with the supporting block 301; a circular structure can be formed between the two arc-shaped strips 302 and the supporting block 301; when the two arc-shaped strips 302 are open, the curing rack 4 can be easily inserted, and when the two arc-shaped strips 302 are closed, ... The two arc-shaped strips 302 and the support block 301 can form a ring structure. This ring structure is used to constrain the curing frame 4, so that it can only rotate within the ring and cannot undergo radial displacement. In order to lock the closed arc-shaped strips 302 and prevent them from being accidentally loosened during the movement of the curing frame 4, the ends of the two arc-shaped strips 302 away from the support block 301 are integrally formed with outward flanges 303. In order to achieve quick locking and loosening, a through groove 304 is provided on one side of each of the two outward flanges 303. The two through grooves 304 are connected by conventional bolts 305 in the art. When the bolts 305 are tightened, the two outward flanges 303 move closer to each other, causing the arc-shaped strips 302 to hug the curing frame 4, thereby achieving axial and radial positioning of the curing frame 4.

[0032] Example 3: Based on Example 2, as follows Figure 6 As shown, in order to facilitate the flexible movement of the curing rack 4 on the bottom wall of the curing chamber body 1, the curing rack 4 includes a movable seat 401 and a curing rack body 402 vertically fixed on the movable seat 401; the movable seat 401 can move on the bottom wall of the curing chamber body 1; the movable seat 401 is the part of the curing rack 4 that contacts the bearing mechanism 3 and the curing chamber body 1. It needs to be connected to the bearing mechanism 3 and be able to move inside the curing chamber body 1, while the curing rack body 402 is used to directly hang the electrode plates and ensure that the spacing between the electrode plates is uniform.

[0033] Among them, such as Figures 6-7As shown, in order to achieve rapid docking between the movable seat 401 and the supporting mechanism 3, and to enable the curing rack 4 to rotate during movement, the movable seat 401 includes a horizontally arranged positioning cylinder 4011. The positioning cylinder 4011 is coaxially arranged with the annular structure formed between the two arc-shaped strips 302 and the supporting block 301, and the positioning cylinder 4011 can rotate within the annular structure. This coaxial arrangement allows the positioning cylinder 4011 to rotate freely within the annular structure, providing a degree of freedom for the rotation of the curing rack 4. To support the weight of the entire curing rack 4 and the electrode plate, and to enable it to move smoothly on the bottom wall of the curing chamber body 1, a pair of first crossbars 4012 are horizontally bolted side by side inside the positioning cylinder 4011. The lower surface of 012 is vertically connected with a pair of conventional casters 4013 in the art; the first crossbar 4012 serves as a supporting frame, transferring weight to the casters 4013, which have omnidirectional movement characteristics and can adapt to the straight and arc segments of the belt 203's movement, reducing frictional resistance; in order to improve the overall structural strength of the movable seat 401 and prevent the first crossbar 4012 from deforming, the two first crossbars 4012 are connected by a pair of second crossbars 4014; the second crossbars 4014 play a lateral bracing role, enhancing the stability of the frame; both ends of the two second crossbars 4014 are bolted to the inner side of the positioning cylinder 4011, thereby connecting the entire movable seat 401 into a rigid integral frame.

[0034] Among them, such as Figure 6 As shown, in order to stably suspend a large number of electrode plates and ensure that airflow can pass through the gaps between the electrode plates, the curing frame body 402 includes two pairs of columns 4021, each vertically bolted to the upper surface of two second crossbars 4014; the columns 4021 serve as the main vertical supports, bearing the weight of the electrode plates; in order to form a multi-layer electrode plate suspension layer in the horizontal direction, the columns 4021 on the same end of the two second crossbars 4014 are connected by multiple material-carrying rods 4022 arranged side by side from top to bottom; the material-carrying rods 4022 are horizontally arranged, and the electrode... The plate can be directly hung on the material carrier 4022. Multiple material carriers 4022 form a multi-layer suspension space, which greatly increases the number of single curing processes. In order to improve the bending stiffness of the column 4021 when subjected to the lateral force of the plate or the impact of wind, the two columns 4021 on any second crossbar 4014 are connected by multiple parallel reinforcing rods 4023. The reinforcing rods 4023 connect the two columns 4021 on the same side to form a stable frame structure, which effectively prevents the columns 4021 from tilting or shaking.

[0035] Example 4: Based on Example 3, as follows Figure 3 and Figure 6As shown, to address the issue of uneven airflow to the plates near the sidewalls of the curing chamber and those near the center when the curing rack 4 moves along the circular path, a directional mechanism 5 is installed inside the curing chamber body 1. This directional mechanism 5 drives the curing rack 4 to rotate while it moves, ensuring that each plate periodically faces the air inlet 103. To achieve this function, the directional mechanism 5 includes a pair of racks 501 horizontally positioned on opposite sides of the circulating conveying mechanism 2, and multiple external toothed rings bolted to the outer periphery of the positioning cylinder 4011. 502; Two racks 501 are bolted to the opposite side walls of the curing chamber body 1 via multiple support columns 503, meaning the racks 501 are fixed and serve as tracks for driving the curing frame 4 to rotate. When the circulating conveying mechanism 2 drives the curing frame 4, the outer toothed ring 502 on any curing frame 4 can mesh with any rack 501. Since the racks 501 are fixed, and the curing frame 4 moves along the length of the racks 501 under the traction of the belt 203, the outer toothed ring 502 is forced to roll on the rack 501 it meshes with while moving. The rolling motion of the outer toothed ring 502 is transmitted to the entire curing frame 4 through the positioning cylinder 4011, realizing the rotation of the curing frame 4.

[0036] By setting the orientation mechanism 5, the curing rack 4 revolves along the circular path while also rotating continuously. For example, when a curing rack 4 passes the air inlet 103, the electrode plate facing the air inlet 103 receives the hot air first. As the curing rack 4 continues to move forward and rotate, the electrode plate that was originally facing away from the air inlet 103 will gradually turn towards the air inlet 103 and thus also receive the hot air. In this way, each electrode plate can be periodically and evenly exposed to the hot air, which greatly improves the uniformity of curing and the overall quality.

[0037] Example 5: Based on Example 4, as follows Figure 2 and Figures 8-9As shown, to ensure the curing rack 4 remains stable during rotation and prevent it from shaking, a guide mechanism 6 is installed on the top of the curing chamber body 1. The guide mechanism 6 is used to constrain the movement trajectory of the curing rack 4 and keep its movement trajectory stable. To achieve this purpose, the guide mechanism 6 includes a horizontally arranged guide rail 601 and multiple crosses 602 that are horizontally bolted to the top of the curing rack body 402. The shape of the guide rail 601 is consistent with the shape of the belt 203 installed on the pulley 202, ensuring that the movement paths of the top and bottom of the curing rack 4 are completely synchronized. The guide rail 601 includes a pair of parallel straight sections, and the two straight sections are connected by a semi-circular section at the same end. The straight section and the semi-circular section are integrally welded. The guide rail 601 is bolted to the top wall of the curing chamber body 1 by multiple parallel brackets 603. The four ends of the crosses 602 are bolted to two pairs of columns of the curing rack body 402. At the top of 4021, the four columns 4021 at the top are connected into a whole, which improves the rigidity of the top structure; the middle of the cross 602 is vertically bolted to the mounting column 604; the mounting column 604 is fitted with a movable sleeve 605; the circumferential sidewall of the movable sleeve 605 can abut against the outer side of the guide rail 601, and this contact restricts the top of the curing rack 4 from shifting outward; the upper end of the movable sleeve 605 is rotatably connected to the connecting block 606; the lower surface of the connecting block 606 is vertically rotatably connected to the roller 607; the circumferential sidewall of the roller 607 can abut against the inner side of the guide rail 601; the roller 607 can rotate, changing sliding friction into rolling friction, reducing frictional resistance; through the contact of the movable sleeve 605 and the roller 607 with the outer and inner sides of the guide rail 601 respectively, a clamping structure is formed, thereby accurately guiding the curing rack 4 to move along the guide rail 601, preventing the curing rack 4 from tilting or derailing under centrifugal force or airflow impact.

[0038] Among them, such as Figure 8 As shown, to facilitate the connection or disassembly between the curing rack 4 and the guide mechanism 6, the movable sleeve 605 is slidably fitted with the mounting post 604; the lower end of the movable sleeve 605 is connected to the upper surface of the cross 602 by a tension spring 608; the tension spring 608 is sleeved on the outer periphery of the mounting post 604. When it is necessary to separate the curing rack 4 from the guide mechanism 6, by pushing the movable sleeve 605 upward, the movable sleeve 605 and the roller 607 move simultaneously to the top of the guide rail 601. Then, by rotating the connecting block 606, the roller 607 rotates to the outside of the guide rail 601. Then, the movable sleeve 605 is released, and under the elastic action of the tension spring 608, the movable sleeve 605 moves downward to its reset position, thereby realizing the removal of the curing rack 4 from the guide mechanism 6, effectively ensuring the connection effect between the curing rack 4 and the guide mechanism 6.

[0039] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
