Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery grids, and in particular to lead-acid battery grid casting equipment based on a microporous jet cooling structure. Background Art

[0002] In the structure of lead-acid batteries, the grid serves as the "skeleton" of the battery and directly affects the battery's charge and discharge performance and service life.

[0003] In actual production scenarios, the production of lead-acid battery grids generally includes processes such as casting, die-cutting, cooling, and palletizing. Specifically, after being demolded from casting, the grid needs to pass through a die-cutting machine to remove burrs. Then, the grid ears need to be hung on a conveyor rack and pushed backward by a mechanical structure. During this process, it is cooled by air or water to reduce its temperature to an appropriate temperature range. This cooling method has many disadvantages:

[0004] Since it is difficult to maintain consistent distances between grids during transportation (the grids will sway slightly during transportation, causing uneven spacing between grids), when using cooling methods such as air cooling or water cooling, the disordered grid spacing will disrupt the normal distribution of airflow or water flow, making it impossible for the cooling medium to act evenly on the surface of each grid, resulting in frequent uneven cooling of the grids. Uneven cooling will lead to differences in thermal stress in different parts of the grid due to different cooling rates, which can easily cause problems such as grid deformation and inconsistent internal microstructure, thereby negatively affecting key performance indicators such as the grid's conductivity and mechanical strength, ultimately reducing the overall quality and performance stability of the lead-acid battery. Summary of the Invention

[0005] In response to the above-mentioned shortcomings of the prior art, the present invention provides a lead-acid battery grid casting equipment based on a microporous jet cooling structure, which can effectively solve the problem in the prior art that when the grids are mounted on a conveyor rack waiting for cooling, the uneven spacing between the grids causes the cooling medium to be unable to diffuse stably between the gaps, resulting in uneven cooling.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a lead-acid battery grid casting device based on a microporous jet cooling structure, comprising:

[0008] Two guide racks are arranged at the rear of the grid die-cutting machine and are fixedly connected to the chassis in a front-to-back symmetrical manner. The left end of the guide rack is designed to be arc-shaped, and the end where the two arc segments are close to each other is provided with a chamfer for centering the grid;

[0009] The material transfer part includes a rotating shaft, which is rotatably connected between the front and rear wall panels of the chassis, and a material transfer mechanism for transferring the die-cut grid to the guide rack is rotatably mounted on the rotating shaft;

[0010] The conveying part includes a mounting seat, two of which are fixedly connected symmetrically on the left and right sides below the guide frame, and the two mounting seats located on the same guide frame are commonly connected to a conveying mechanism that moves the conveying grid to the right and keeps the grid stable during movement;

[0011] The chassis is also provided with a cooling mechanism for cooling the grid from the upper and lower sides during the grid conveying process. The cooling mechanism, material moving mechanism and conveying mechanism are commonly connected with a driving mechanism for driving the three to operate synchronously.

[0012] Furthermore, the material moving mechanism includes a mounting block, two of which are symmetrically fixedly connected to the rotating shaft in the front and rear directions, and a support plate is fixedly connected to the two mounting blocks, and a support bar is fixedly connected to the support plate for supporting the grid during the movement process.

[0013] Furthermore, the conveying mechanism includes a material supporting seat, a strip groove is provided on the horizontal section of the material guide frame, and a material supporting seat is slidably connected in the strip groove. The upper end surface of the material supporting seat is evenly provided with a plurality of grooves for placing the grid ears in the left and right directions. The horizontal section of the material guide frame is fixedly connected with an upper limit frame for supporting the grid ears near the inner side. The two material guide frames are fixedly connected with a lower limit frame for limiting the lower end of the grid through an L-shaped plate. A plurality of limit grooves for placing the grid are evenly provided on the upper limit frame and the lower limit frame. The material supporting seat and the mounting seat are jointly connected with a linkage component and a one-way rotation component for driving them to rotate clockwise.

[0014] Furthermore, the linkage assembly includes a columnar block, the lower end of the material support seat is fixedly and rotatably connected to the columnar block through a rectangular plate, a short shaft is rotatably connected to the mounting seat, and the end of the short shaft close to the material support seat is fixedly connected to the rotating wheel, and the columnar block is fixedly connected to the rotating wheel and is eccentrically arranged between the rotating wheel.

[0015] Furthermore, the one-way rotating component includes an end face ratchet 1, which is slidably sleeved on the short shaft and has a spring arranged between it and the mounting seat. The end of the short shaft away from the rotating wheel is rotatably connected to a connecting shaft, and a fixed sleeve on the connecting shaft is provided with an end face ratchet 2 that cooperates with the end face ratchet 1. The two connecting shafts located on the same side are connected by pulley 1 and belt 1. The left connecting shaft 1 and the rotating shaft are connected by pulley 2 and belt 2. When the pulley 2 on the rotating shaft rotates 90 degrees, it will drive the pulley 2 on the connecting shaft to rotate 360 degrees.

[0016] Furthermore, the driving mechanism includes a transmission shaft, and four transmission shafts are rotatably connected to the chassis in a matrix arrangement. The four transmission shafts are connected by pulley three and belt three. A quarter gear is symmetrically fixed on the rotating shaft, and a rack is engaged with the lower end of the quarter gear. The rack is slidably connected to the chassis through a slide rail, and a limit block that cooperates with the rack is fixedly connected to the slide rail.

[0017] Furthermore, the cooling mechanism includes a ventilation duct, which is fixedly installed on the horizontal sections above the two lower belts three through a connecting piece. The outer surface of the ventilation duct is evenly penetrated from front to back and has multiple jet holes inclined to the left front. The horizontal sections above the two upper belts three are also fixedly installed on the ventilation duct through a connecting piece. The upper ventilation duct and the lower ventilation duct are staggered and their jet holes are inclined to the right rear. Both ventilation ducts are connected to the air cooler.

[0018] Furthermore, a connecting seat is fixedly provided on the lower ventilation duct, and the left end of the connecting seat is fixedly connected to a push piece that cooperates with the rack, and the left end of the push piece and the right end of the rack are fixedly connected to magnetic blocks that attract each other. The connecting seat is also fixedly connected to an electric push rod connected to the side wall of the chassis through a guide rail.

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] 1. In the present invention, the rotation of the rotating shaft will drive the short shaft and the connecting shaft of the conveying mechanism through the pulley transmission. At the same time, the engagement of the rack and the quarter gear drives the material moving mechanism to rotate, and the movement of the electric push rod synchronously drives the ventilation pipe of the cooling mechanism to move. This design realizes the synchronous operation of the three core actions of material moving, feeding and air sweeping through a single drive source, enhances the correlation between the various mechanisms, reduces the coordination error of multiple drive sources, makes the response of each action more timely, avoids the synchronization problem caused by the independent drive of each mechanism in traditional equipment, significantly improves the conveying efficiency of the grid, and ensures the continuity of the production process.

[0021] 2. The groove on the upper end surface of the material support seat in the present invention is used to position and place the grid ears, while the upper limit frame supports the ears and the lower limit frame limits the lower end of the grid, ensuring that the grid is fixed in position and has consistent spacing during movement. Compared with the traditional disordered conveying method of "the rear grid pushes the front grid", this design avoids the spacing disorder problem caused by conveying shaking, allowing the low-temperature gas to stably enter the grid gap and act evenly on the grid surface, effectively solving the problem of uneven distribution of the cooling medium and improving the cooling uniformity.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Example:

[0035] See also Figures 1-8 The present invention provides a technical solution: a lead-acid battery grid casting device based on a microporous jet cooling structure, comprising:

[0036] Two guide racks 1 are arranged behind the grid die-cutting machine and are fixedly connected to the chassis symmetrically. The left end of the guide rack 1 adopts an arc design and the end where the two arc sections are close to each other is provided with a chamfer for centering the grid.

[0037] The material moving part 2, the material moving mechanism 22 includes a rotating shaft 21, the rotating shaft 21 is rotatably connected between the front and rear wall panels of the chassis, and a material moving mechanism 22 for moving the die-cut plate grid to the guide rack 1 is rotatably installed on the rotating shaft 21.

[0038] The conveying part 3 includes a mounting seat 31, two of which are fixedly connected symmetrically on the left and right below the material guide frame 1. The two mounting seats 31 located on the same material guide frame 1 are commonly connected to a conveying mechanism 32 that moves the conveying grid to the right and keeps the grid stable during movement.

[0039] The chassis is also provided with a cooling mechanism 33 for cooling the grid from the upper and lower sides during the grid conveying process. The cooling mechanism 33, the material moving mechanism 22 and the conveying mechanism 32 are connected to a driving mechanism 34 for driving the three to operate synchronously.

[0040] In the specific work, when the grid injected into the mold cavity solidifies and forms a rough mold after demoulding, the rough mold will be transported to the die-cutting equipment by the conveying equipment, and the die-cutting equipment will cut off the burrs at the corners of the rough mold to form a rough mold. Figure 1 The shape shown in the figure, the die-cutting grid is transported to the material transfer mechanism 22 by the conveying equipment, and the material transfer mechanism 22 drives it to rotate ninety degrees and transfer it to the horizontal section of the guide rack 1, and then the grid is lifted by the conveying mechanism 32 and moved a short distance to the right. The above process is repeated several times, and the grid on the conveying mechanism 32 can be transferred to the guide rack 1 and the guide rack 1 is moved from left to right in turn. While the grid is on the guide rack 1 from left to right, the cooling mechanism 33 sweeps air from above and below to cool the guide rack 1. The movement of the above-mentioned material transfer mechanism 22, the conveying mechanism 32 and the cooling mechanism 33 are all driven by the driving mechanism 34 to move synchronously, thereby realizing step-by-step material transfer and transportation, and ensuring cooling efficiency and cooling uniformity.

[0041] It is worth noting that the equipment involved in the above-mentioned casting, die-cutting and conveying processes are all existing technologies and will not be illustrated or described in the implementation.

[0042] The material moving mechanism 22 includes a mounting block 221, two of which are symmetrically fixedly connected to the rotating shaft 21 in the front and rear directions. A supporting plate 222 is fixedly connected to the two mounting blocks 221, and a supporting bar 223 is fixedly connected to the supporting plate 222 for supporting the grid during the moving process.

[0043] The conveying mechanism 32 includes a material supporting seat 321, a strip groove is provided on the horizontal section of the material guide frame 1, and the material supporting seat 321 is slidably connected in the strip groove, and the upper end surface of the material supporting seat 321 is evenly provided with a plurality of grooves 3211 for placing the grid ears in the left and right directions. The horizontal section of the material guide frame 1 and the position close to the inner side are fixedly connected with an upper limit frame 322 for supporting the grid ears, and the two material guide frames 1 are fixedly connected with a lower limit frame 323 for limiting the lower end of the grid through an L-shaped plate. A plurality of limit grooves for placing the grid are evenly provided on the upper limit frame 322 and the lower limit frame 323, and the material supporting seat 321 and the mounting seat 31 are commonly connected with a linkage component 324 and a one-way rotation component 325 for driving them to rotate clockwise.

[0044] The linkage assembly 324 includes a cylindrical block 3241, the lower end of the support seat 321 is fixedly and rotatably connected to the cylindrical block 3241 through a rectangular plate, a short shaft 3242 is rotatably connected to the mounting seat 31, and one end of the short shaft 3242 close to the support seat 321 is fixedly connected to the rotating wheel 3243, and the cylindrical block 3241 is fixedly connected to the rotating wheel 3243 and is eccentrically arranged between the rotating wheel 3243.

[0045] The one-way rotating component 325 includes an end face ratchet 1 3251, which is slidably sleeved on the short shaft 3242 and has a spring 3252 arranged between it and the mounting seat 31. The end of the short shaft 3242 away from the rotating wheel 3243 is rotatably connected to the connecting shaft 3253, and the connecting shaft 3253 is fixedly sleeved with an end face ratchet 2 3254 that cooperates with the end face ratchet 1 3251. The two connecting shafts 3253 located on the same side are connected to each other through pulley 1 and belt 1. The left connecting shaft 3253 is connected to the rotating shaft 21 through pulley 2 and belt 2. When the pulley 2 on the rotating shaft 21 rotates 90 degrees, it will drive the pulley 2 on the connecting shaft 3253 to rotate 360 degrees.

[0046] The driving mechanism 34 includes a transmission shaft 341, and four transmission shafts 341 are rotatably connected to the chassis in a matrix arrangement. The four transmission shafts 341 are connected to each other through pulley three and belt three. A quarter gear 342 is symmetrically fixed on the rotating shaft 21, and a rack 343 is engaged at the lower end of the quarter gear 342. The rack 343 is slidably connected to the chassis through a slide rail, and a limit block 344 that cooperates with the rack 343 is fixedly connected to the slide rail.

[0047] The cooling mechanism 33 includes a ventilation pipe 331, and the ventilation pipe 331 is fixedly installed on the horizontal sections above the two lower belts three through a connecting piece. The outer surface of the ventilation pipe 331 and the upper position are evenly penetrated from front to back and have multiple jet holes 332 inclined to the left front. The horizontal sections above the two upper belts three are also fixedly installed with a ventilation pipe 331 through a connecting piece. The upper ventilation pipe 331 and the lower ventilation pipe 331 are staggered and their jet holes 332 are inclined to the right rear. The two ventilation pipes 331 are both connected to the air cooler. During cooling, the air cooler first transports the low-temperature gas into the ventilation pipe 331 through the air pipe, and then blows the jet holes 332 on the ventilation pipe 331 to the surface of the grid, so as to achieve a rapid cooling effect.

[0048] A connecting seat 333 is fixedly provided on the lower ventilation pipe 331, and the left end of the connecting seat 333 is fixedly connected to a push piece 334 that cooperates with the rack 343, and the left end of the push piece 334 and the right end of the rack 343 are fixedly connected to magnetic blocks 335 that attract each other. The connecting seat 333 is also fixedly connected to an electric push rod 336 connected to the side wall of the chassis through a guide rail.

[0049] During specific operation, initially, the movable section of the electric push rod 336 is in a retracted state and is located at the rightmost end of the guide rail, the support seat 321 is located below the guide frame 1, the support plate 222 is in a horizontal state, the lower ventilation pipe 331 is located on the right, and the upper ventilation pipe 331 is located on the left. After the conveying equipment conveys the die-cut plate grid to the support plate 222, the electric push rod 336 pushes the lower connecting seat 333 to move to the left, driving the lower belt three to rotate counterclockwise. When the lower connecting seat 333 moves to the left, it will contact the rack 343 and drive the rack 343 to move to the left, thereby driving the quarter gear 342 and the rotating shaft 21 to rotate synchronously clockwise. The rotation of the rotating shaft 21 will drive the support plate 222 and the plate grid thereon to rotate synchronously clockwise, thereby moving the support plate 222 to the guide frame 1. During this period, the chamfer on the arc section of the guide frame 1 will correct the position of the plate grid so that it is in a relatively centered position between the two guide frames 1.

[0050] After the electric push rod 336 pushes the rack 343 to the far left end, it begins to retract, driving the lower connecting seat 333 to move right synchronously. In this process, due to the mutual attraction between the rack 343 and the two magnetic blocks on the push member 334 under the action of magnetic force, the rack 343 will be driven to move right synchronously, thereby driving the rotating shaft 21 and the support plate 222 to rotate counterclockwise and reset synchronously through the quarter gear 342. At this time, the plate grid ear is supported by the horizontal section of the guide rack 1. During the rotation and reset of the support plate 222, the plate grid will be left on the horizontal section of the guide rack 1, thereby realizing the conveying of the plate grid from the support plate 222 to the guide rack 1. Then, when the support plate 222 rotates and resets to the lowest point, the rack 343 cannot continue to move right due to the obstruction of the limit block 344. Then, when the subsequent active section of the electric push rod 336 pushes the lower connecting seat 333 to move left again to this point, it can continue to push the rack 343 to move left and repeat the material moving process, thereby realizing cyclic material moving.

[0051] When the shaft 21 rotates clockwise driven by the rack 343 and the quarter gear 342, the shaft 21 will also drive the connecting shaft 3253 to rotate counterclockwise for one circle synchronously through the pulley 2 and the belt 2, thereby driving the end face ratchet 2 3254 to rotate synchronously for one circle. When the end face ratchet 2 3254 rotates counterclockwise, it will drive the end face ratchet 1 3251 to slide back and forth on the short shaft 3242. During this process, the short shaft 3242 will not rotate. When the shaft 21 rotates clockwise driven by the quarter gear 342 and the shaft 21, the end face ratchet 2 will rotate counterclockwise. 3254 drives the end face ratchet 3251 and the short shaft 3242 to rotate synchronously to the right, thereby driving the rotating wheel 3243 to rotate clockwise, and then driving the support seat 321 to rotate clockwise for one circle through the columnar block 3241. During this period, the upper end of the support seat 321 will move to the top of the guide frame 1, and the position of the grid will be adjusted first through the groove 3211 above, and then the grid with the ear sliding to the bottom of the groove 3211 will be lifted and moved to the corresponding upper limit frame 322 and lower limit frame 323, so as to realize the movement of each grid from left to right on the guide plate in turn.

[0052] It is worth noting that when the grid is located on the upper limit frame 322 and the lower limit frame 323, the guide grooves on the upper limit frame 322 and the lower limit frame 323 will simultaneously limit the ears and the lower end of the grid to a certain extent, so as to avoid the impact force generated by the low-temperature gas being discharged from the micropores causing the grid to shake, thereby causing uneven distribution of temperature gas.

[0053] When the grid moves to the right side driven by the support seat 321, the grid ear will fall on the guide rack 1, and then when the support seat 321 moves the rightmost grid on it to the guide rack 1 next time, it will push the previous grid to slide to the right through its right end. This process is repeated, thereby realizing automatic stacking of the grids after cooling.

[0054] In addition, when the electric push rod 336 pushes the upper belt three and the lower belt three to rotate counterclockwise and clockwise synchronously through the connecting seat 333, it will also drive the upper and lower ventilation pipes 331 to move synchronously with the belt three connected to it. Since the upper ventilation pipe 331 is installed in the horizontal section below the upper belt three, and the lower ventilation pipe 331 is installed in the horizontal section above the lower belt three, when the upper and lower belts three rotate synchronously, the upper and lower ventilation pipes 331 move synchronously, thereby realizing staggered reverse wind sweeping. The advantage of this wind sweeping method over the synchronous moving wind sweeping method is that: during the reverse movement of the two, a dynamic balance of the cooling energy of the upper and lower surfaces can be achieved within the movement cycle, preventing the upper and lower surface cooling from being asynchronous due to the synchronous movement of the upper and lower airflows, thereby improving the cooling efficiency and cooling uniformity.

[0055] It is worth noting that the lead-acid battery grid casting equipment based on the microporous jet cooling structure has the following advantages:

[0056] Advantage 1. In this embodiment, the rotation of the rotating shaft 21 will indirectly drive the short shaft 3242 and the connecting shaft 3253 of the conveying mechanism 32. At the same time, the engagement of the rack 343 and the quarter gear 342 drives the material moving mechanism 22 to rotate, and the movement of the electric push rod 336 synchronously drives the ventilation pipe 331 of the cooling mechanism 33 to move. This design realizes the synchronous operation of the three core actions of material moving, feeding and air sweeping through a single drive source, enhances the correlation between the various mechanisms, reduces the coordination error of multiple drive sources, makes the response of each action more timely, avoids the synchronization problem caused by the independent driving of each mechanism in traditional equipment, significantly improves the conveying efficiency of the grid, and ensures the continuity of the production process.

[0057] Advantage 2: In this embodiment, the groove 3211 on the upper end surface of the material support seat 321 is used to position and place the grid ears, while the upper limit frame 322 supports the ears and the lower limit frame 323 limits the lower end of the grid, ensuring that the grid is fixed in position and the spacing is consistent during movement. Compared with the traditional disordered conveying method of "the rear grid pushes the front grid", this design avoids the spacing disorder problem caused by grid size tolerance and conveying shaking, so that the low-temperature gas can stably enter the grid gap and act evenly on the grid surface, effectively solving the problem of uneven distribution of the cooling medium, improving the cooling uniformity, and reducing the problems of grid deformation and internal structure inconsistency caused by uneven cooling.

[0058] Advantage Three: In this embodiment, the jet holes 332 of the upper and lower ventilation pipes 331 are tilted in opposite directions (the lower jet hole 332 is tilted toward the left front, and the upper jet hole 332 is tilted toward the right rear), and they move synchronously in opposite directions under the drive mechanism 34. This staggered air sweeping method achieves a dynamic balance of cooling energy between the upper and lower surfaces of the grid during the movement cycle, avoiding the cooling asynchrony problem caused by the synchronous movement of the upper and lower airflows. Low-temperature gas sweeps the grid from the top and bottom in opposite directions, more comprehensively covering the grid surface, reducing cooling blind spots, and enhancing the gas flow stability within the grid gaps, thereby improving cooling efficiency, ensuring a uniform drop in the overall temperature of the grid, and further enhancing the grid's electrical conductivity and mechanical strength.

[0059] Advantage 4: In this embodiment, when the grid moves to the rightmost end of the guide rack 1, the support seat 321 rotates clockwise (driven by the linkage component 324 and the one-way rotation component 325) to accurately place the grid ear at the bottom of the groove 3211, and uses the moving trajectory of the support seat 321 to achieve the stacking of the grid. This design enables the cooled grids to be stacked in an orderly manner, avoiding the problem of chaotic grid stacking in traditional conveying methods, providing convenience for subsequent stacking and conveying processes, reducing manual sorting costs, and improving the degree of production automation.
