Description

Technical Field

[0001] The present invention relates to the technical field of lead - acid battery grids, and particularly to a lead - acid battery grid casting device based on a micro - hole jet cooling structure. Background Art

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

[0003] In actual production scenarios, the production of lead - acid battery grids generally includes processes such as casting, die - cutting, cooling, and palletizing and conveying. Specifically, after the grid is cast and demolded, the grid needs to pass through a die - cutting machine to remove burrs. Then, the ears of the grid need to be hung on a conveying rack and pushed backward by a mechanical structure. During this process, it is cooled by air cooling or water cooling to reduce its temperature to an appropriate temperature range. This cooling method has many drawbacks: Since it is difficult to keep the distance between each grid consistent during the conveying process (because the grids will shake slightly during the conveying process, making the distances between the grids uneven), when using cooling means such as air cooling or water cooling, the disordered grid spacing will disrupt the normal distribution of the air flow or water flow, making the cooling medium unable to act uniformly on the surface of each grid, resulting in frequent uneven cooling of the grids; uneven cooling will cause differences in thermal stress generated by different parts of each grid due to different cooling rates, easily leading to problems such as grid deformation and inconsistent internal micro - structures, which will in turn have a negative impact on key performance indicators such as the conductive performance and mechanical strength of the grid, and ultimately reduce the overall quality and performance stability of lead - acid batteries. Summary of the Invention

[0004] Aiming at the above - mentioned drawbacks of the prior art, the present invention provides a lead - acid battery grid casting device based on a micro - hole jet cooling structure, which can effectively solve the problem in the prior art that when the grids are placed on the conveying rack waiting for cooling, the uneven spacing between each grid causes the cooling medium to be unable to stably diffuse in the gaps, resulting in uneven cooling.

Detailed implementation manners

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Embodiment:

[0021] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a lead-acid battery grid casting device based on a micro-jet cooling structure, including: Two guide frames 1 arranged behind the grid die cutter and symmetrically fixedly connected to the chassis in the front and back. The left end of the guide frame 1 is designed in an arc shape, and chamfers for centering the grid are provided at one end where the two arc segments are close to each other.

[0022] A material transfer part 2, the material transfer mechanism 22 of which includes a rotating shaft 21. The rotating shaft 21 is rotatably connected between the front and back wall plates of the chassis, and a material transfer mechanism 22 for transferring the die-cut grid onto the guide frame 1 is rotatably installed on the rotating shaft 21.

[0023] A conveying part 3, the conveying part 3 includes a mounting seat 31. Two mounting seats 31 are symmetrically and fixedly connected to the left and right below the guide frame 1. A conveying mechanism 32 for conveying the grid to move rightward and keeping the grid stable during the movement is commonly connected to the two mounting seats 31 located on the same mounting seat 31.

[0024] Among them, a cooling mechanism 33 for cooling the grid from the upper and lower sides during the grid conveying process is further provided on the chassis. A driving mechanism 34 for driving the cooling mechanism 33, the material transfer mechanism 22, and the conveying mechanism 32 to operate synchronously is commonly connected to the cooling mechanism 33, the material transfer mechanism 22, and the conveying mechanism 32.

[0025] During specific operation, when the grid injected into the mold cavity solidifies and forms a rough mold after demolding, the rough mold will be conveyed by a conveying device to a die-cutting device, and the die-cutting device will cut off the burrs at the edges and corners of the rough mold to make it form as Figure 1In the shape shown, after die-cutting, the grid is conveyed by the conveying device to the material transfer mechanism 22, and the material transfer mechanism 22 drives it to rotate 90 degrees and transfer it to the horizontal section of the guide frame 1. Then, the conveying mechanism 32 lifts the grid and moves it a short distance to the right. The above process is repeated several times, and the grids on the conveying mechanism 32 can be sequentially transferred to the guide frame 1 and the guide frame 1 is moved from left to right. During the period when the grid moves from left to right on the guide frame 1, the cooling mechanism 33 will blow air from above and below to cool the guide frame 1. The movements of the above-mentioned material transfer mechanism 22, conveying mechanism 32, and cooling mechanism 33 are synchronously driven by the drive mechanism 34, thereby realizing step-by-step material transfer and conveying, and ensuring the cooling efficiency and uniformity of cooling.

[0026] It should be noted that the equipment involved in the above casting, die-cutting, and conveying processes are all prior arts, and no illustrations and descriptions will be given to them in the implementation.

[0027] The material transfer mechanism 22 includes mounting blocks 221. Two mounting blocks 221 are symmetrically and fixedly connected to the front and rear on the rotating shaft 21. A support plate 222 is fixedly connected to the two mounting blocks 221 together. A support strip 223 for supporting the grid during the movement is fixedly connected to the support plate 222.

[0028] The conveying mechanism 32 includes a material supporting seat 321. A strip-shaped groove is formed through the horizontal section of the guide frame 1, and the material supporting seat 321 is slidably connected in the strip-shaped groove. A plurality of grooves 3211 for placing the ears of the grid are uniformly formed in the upper end surface of the material supporting seat 321 in the left-right direction. An upper limit frame 322 for supporting the ears of the grid is fixedly connected to the position of the horizontal section of the guide frame 1 close to the inner side. A lower limit frame 323 for limiting the lower end of the grid is fixedly connected to the two guide frames 1 through an L-shaped plate. A plurality of limit grooves for placing the grid are uniformly formed in the upper limit frame 322 and the lower limit frame 323. A linkage assembly 324 and a one-way rotation assembly 325 for driving it to rotate clockwise are commonly connected to the material supporting seat 321 and the mounting seat 31.

[0029] The linkage assembly 324 includes a cylindrical block 3241. The lower end of the material supporting 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. A runner 3243 is fixedly connected to the end of the short shaft 3242 close to the material supporting seat 321. The cylindrical block 3241 is fixedly connected to the runner 3243 and is eccentrically arranged with the runner 3243.

[0030] 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, and the end of the short shaft 3242 away from the rotating wheel 3243 is rotatably connected with a connecting shaft 3253, and an end face ratchet 2 3254 matching the end face ratchet 1 3251 is fixedly sleeved on the connecting shaft 3253, and the two connecting shafts 3253 located on the same side are connected to each other through a pulley 1 and a belt 1, and the left connecting shaft 3253 is connected to the rotating shaft 21 through a pulley 2 and a belt 2, and 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.

[0031] 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 meshed 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.

[0032] The cooling mechanism 33 includes a ventilation pipe 331, and the ventilation pipe 331 is fixedly installed on the upper horizontal sections of the two lower belts three through a connecting piece. The outer surface of the circumference 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 ventilation pipes 331 through connecting pieces. The upper ventilation pipe 331 is staggered with the lower ventilation pipe 331, and its jet holes 332 are inclined to the right rear. Both ventilation pipes 331 are connected to the air cooler. During cooling, the air cooler first transports the low-temperature gas to 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.

[0033] A connecting seat 333 is fixedly sleeved 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.

[0034] During specific operation, initially, the movable section of the electric push rod 336 is in a contracted state and located at the rightmost end of the guide rail. The material supporting seat 321 is located below the material guiding frame 1, the supporting plate 222 is in a horizontal state, the lower ventilation pipe 331 is located on the right side, and the upper ventilation pipe 331 is located on the left side. After the conveying equipment transports the die-cut grid to the supporting plate 222, the electric push rod 336 pushes the lower connecting seat 333 to move leftward, 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 leftward, thereby driving the quarter gear 342 and the rotating shaft 21 to rotate clockwise synchronously. The rotation of the rotating shaft 21 will drive the supporting plate 222 and the grid thereon to rotate clockwise synchronously, so as to move the supporting plate 222 to the material guiding frame 1. During this period, the chamfer on the arc section of the material guiding frame 1 will correct the position of the grid, making it in a relatively centered position between the two material guiding frames 1.

[0035] After the electric push rod 336 pushes the rack 343 to the leftmost end, it starts to contract, driving the lower connecting seat 333 to move rightward synchronously. During this process, due to the mutual attraction of the two magnetic blocks on the rack 343 and the pusher 334 under the action of magnetism, the rack 343 will be driven to move rightward synchronously, thereby driving the rotating shaft 21 and the supporting plate 222 to rotate counterclockwise and reset synchronously through the quarter gear 342. At this time, since the ear part of the grid is lifted by the horizontal section of the material guiding frame 1, during the rotation and reset of the supporting plate 222, the grid will be left on the horizontal section of the material guiding frame 1, thereby realizing the conveying of the grid from the supporting plate 222 to the material guiding frame 1. Then, when the supporting plate 222 rotates and resets to the lowest position, the rack 343 cannot continue to move rightward due to the block of the limit block 344. Furthermore, when the movable section of the subsequent electric push rod 336 pushes the lower connecting seat 333 to move leftward to this position again, it can continue to push the rack 343 to move leftward to repeat the material moving process, thereby realizing cyclic material moving.

[0036] During the process of the above-mentioned rotating shaft 21 rotating clockwise driven by the rack 343 and the quarter gear 342, it will also drive the coupling shaft 3253 to rotate counterclockwise synchronously for one week through the second pulley and the second belt, thereby driving the second end face ratchet 3254 to rotate synchronously for one week. When the second end face ratchet 3254 rotates counterclockwise, it will drive the first end face ratchet 3251 to slide back and forth on the short shaft 3242. During this process, the short shaft 3242 will not rotate. When the rotating shaft 21 rotates clockwise driven by the quarter gear 342 and the rotating shaft 21, it will drive the first end face ratchet 3251 and the short shaft 3242 to rotate synchronously to the right through the second end face ratchet 3254, thereby driving the runner 3243 to rotate clockwise, and then driving the material supporting seat 321 to rotate clockwise for one week through the cylindrical block 3241. During this period, the upper end of the material supporting seat 321 will move above the material guiding frame 1, first adjust the position of the grid through the upper groove 3211, and then lift and move the grid with the ear part sliding to the bottom of the groove 3211 to the corresponding upper limiting frame 322 and lower limiting frame 323, so as to realize the sequential movement of each grid from left to right on the material guiding plate.

[0037] It should be noted that when the grid is located on the upper limiting frame 322 and the lower limiting frame 323, the guide grooves on the upper limiting frame 322 and the lower limiting frame 323 will simultaneously limit the ear part and the lower end of the grid to a certain extent, so as to avoid the situation that the grid shakes due to the impact force generated by the low-temperature gas being exported from the micropores, and further cause uneven distribution of the temperature gas.

[0038] When the grid moves to the right driven by the material supporting seat 321, the ear part of the grid will fall on the material guiding frame 1. Then, when the material supporting seat 321 moves the rightmost grid on it to the material guiding frame 1 next time, it will push the previous grid to slide to the right through its right end. This process is repeated, and thus the automatic stacking of the grids after cooling is realized.

[0039] In addition, during the process of the electric push rod 336 driving 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 thereto. Since the upper ventilation pipe 331 is installed on the horizontal section below the upper belt three, and the lower ventilation pipe 331 is installed on 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, so as to realize staggered reverse air sweeping. The advantage of this air sweeping method compared with synchronous moving air sweeping is that: during the reverse movement of the two, the dynamic balance of the cooling energy on the upper and lower surfaces can be realized within the movement cycle, preventing the asynchronous cooling of the upper and lower surfaces caused by the synchronous movement of the upper and lower airflows, so as to improve the cooling efficiency and the uniformity of cooling.

[0040] It should be noted that the above-mentioned lead-acid battery grid casting equipment based on the microporous jet cooling structure has the following advantages: Advantage 1: In this embodiment, the rotation of the rotating shaft 21 indirectly drives the short shaft 3242 and the coupling 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 transfer mechanism 22 to rotate, and the movement of the electric push rod 336 synchronously drives the movement of the ventilation pipe 331 of the cooling mechanism 33. This design realizes the synchronous operation of the three core actions of material transfer, feeding, and air sweeping through a single driving source, enhances the correlation between mechanisms, reduces the coordination error of multiple driving sources, makes each action respond more promptly, avoids the asynchronism problem caused by the independent driving of each mechanism in traditional equipment, significantly improves the conveying efficiency of the grid, and ensures the coherence of the production process.

[0041] Advantage 2: In this embodiment, the groove 3211 on the upper end surface of the material supporting seat 321 is used to position and place the grid ear part, and the upper limit frame 322 supports the ear part, and the lower limit frame 323 limits the lower end of the grid, ensuring that the grid is fixed in position and has a consistent spacing during the movement. Compared with the traditional disorderly conveying method of "pushing the front grid with the rear grid", this design avoids the problem of spacing disorder caused by grid size tolerance and conveying vibration, enables the low-temperature gas to stably enter the grid gap, uniformly act on the grid surface, effectively solves the problem of uneven distribution of the cooling medium, improves the cooling uniformity, and reduces problems such as grid deformation and inconsistent internal structure caused by uneven cooling.

[0042] Advantage 3: In this embodiment, the jet holes 332 of the upper and lower ventilation pipes 331 have opposite inclination directions (the lower jet holes 332 are inclined forward to the left, and the upper jet holes 332 are inclined backward to the right), and they move synchronously and in opposite directions under the drive of the drive mechanism 34. This misaligned air sweeping method realizes the dynamic balance of the cooling energy on the upper and lower surfaces of the grid during the movement cycle, avoiding the problem of asynchronous cooling caused by the synchronous movement of the upper and lower airflows. The low-temperature gas blows the grid from the upper and lower sides in opposite directions, can more comprehensively cover the grid surface, reduce the cooling blind area, enhance the flow stability of the gas in the grid gap, thereby improving the cooling efficiency, ensuring that the overall temperature of the grid drops evenly, and further improving the electrical conductivity and mechanical strength of the grid.

[0043] Advantage 4: In this embodiment, when the grid moves to the rightmost end of the guide frame 1, the material supporting seat 321 accurately places the grid ear part at the bottom of the groove 3211 by rotating clockwise (driven by the linkage assembly 324 and the one-way rotation assembly 325), and realizes the stacking of the grids by using the movement trajectory of the material supporting seat 321. This design enables the cooled grids to be stacked orderly, avoids the problem of chaotic stacking of grids in the traditional conveying method, provides convenience for the subsequent palletizing and conveying process, reduces the manual sorting cost, and improves the degree of production automation.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
