Description

Multi-layer battery charging automatic transfer cooling system and control method TECHNICAL FIELD

[0001] The present application belongs to the technical field of new energy battery production, and particularly relates to a multi-layer battery charging automatic transfer cooling system and a control method. BACKGROUND

[0002] Sulfuric acid is an important component of lead-acid batteries, and it plays a decisive role in the performance of lead-acid batteries. At present, most batteries use vacuum injection of sulfuric acid. After the acid is injected, the battery needs to be immediately placed in a water tank for cooling. Because sulfuric acid immediately reacts chemically with the active material inside the battery, a large amount of heat energy is generated. If the cooling is not sufficient, it will cause the decomposition of the active material inside the battery, affecting the performance of the battery. Therefore, water bath cooling is required during the formation of the battery.

[0003] In the current era of rapid development of industrial automation, in order to improve the efficiency of the transfer cooling in the water bath process of the battery formation, a matching system needs to be set up to solve this problem. SUMMARY

[0004] The present application proposes a multi-layer battery charging automatic transfer cooling system and a control method to solve the above technical problems. The specific technical solutions are as follows:

[0005] The present application provides a multi-layer battery charging automatic transfer cooling system, which comprises a steel frame, a water bath assembly fixed on the steel frame in a vertical layered manner, and a transfer assembly arranged correspondingly in a layered manner.

[0010] The side wall of the first slot-shaped hole has a continuous tooth groove.

[0011] The strip-shaped cavity is arranged in the cantilever, and the elastic sheet and the contact sheet are arranged in the cavity.

[0012] One end of the elastic sheet is a fixed end, and the other end is a free end. The fixed end is fixed to the inner wall of the cavity near the first pipe body. The free end is provided with a counterweight.

The two ends of the second spring are respectively connected or abut against the connecting support and the limiting pin. The head of the limiting pin is arranged as an inclined surface. When the cantilever is reset downward, the limiting pin is pressed by the inclined surface. The limiting pin moves along the second strip-shaped hole to press the second spring.

[0020] As the preferred technical scheme of the above, the limiting pin is provided with a vertically-slidable insertion plate, the top of the connecting bracket is provided with a stepped groove with a length smaller than the second strip-shaped hole, the stepped groove is coincident with the second strip-shaped hole, the stepped groove is arranged on the side away from the limiting pin, the insertion plate falls when moving to the stepped groove, the part of the top exposed outside the limiting pin is retracted into the limiting pin, the end of the stepped groove is provided with a slope, and the slope is arranged on the side towards the first strip-shaped hole.

[0057] The overflow tank 202 as a structure for maintaining the liquid level height in the tank body 201 is provided with a notch 204 at the connection with the tank body 201, the notch 204 communicates the overflow tank 202 with the tank body 201, under normal circumstances, the overflow tank 202 is directly welded and fixed on the side wall of the tank body 201 and ensures the sealing of the weld, and the notch 204 can be directly arranged on the tank body 201, and the overflow tank 202 is provided with an overflow pipe assembly, and the height of the upper port of the overflow pipe assembly determines the liquid level height in the tank body 201.

[0058] Figure 4 shows a structure diagram of the overflow pipe assembly, the overflow pipe assembly includes a drainage main pipe 211 and a first pipe body 212, a second pipe body 213 and a third pipe body 214 which are in communication with the drainage main pipe 211, the first pipe body 212, the second pipe body 213 and the third pipe body 214 constitute a complete overflow pipe, and the number of overflow pipes is determined according to the overflow tank 202, that is, at least one overflow pipe is arranged in each overflow tank 202, and is connected with the drainage main pipe 211.

[0059] The first pipe body 212 as the overflow pipe structure is arranged to be movable in the overflow tank 202 to change the height position of the top opening of the first pipe body 212, so that the water in the tank body 201 is discharged through the top opening of the first pipe body 212; the third pipe body 214 is fixed at the bottom of the overflow tank 202, and the third pipe body 214 extends through the overflow tank 202 to the outside and communicates with the drain main pipe 211, and the connection between the third pipe body 214 and the overflow tank 202 should also be sealed; the second pipe body 213 is used to connect the first pipe body 212 and the third pipe body 214, and the second pipe body 213 is arranged as a flexible pipe to adapt to the requirement of changing the position of the first pipe body 212 and ensure the communication between the first pipe body 212 and the third pipe body 214.

[0060] Generally, lead-acid batteries have different size specifications according to the difference in capacity, such as the commonly used 12V / 6AH size of about 150mm*70mm*105mm, 12V / 9AH size of about 180mm*70mm*130mm, and 12V / 24AH size of about 280mm*70mm*200mm. If the height of the cooling water in the tank body 201 is maintained at a high level and cannot be adjusted, the formation cooling requirement of the smaller size battery cannot be met. If the height of the cooling water in the tank body 201 is maintained at a low level and cannot be adjusted, the shell of the larger size battery cannot be immersed, resulting in poor cooling effect.

[0061] The first pipe body 212 is fixed with a retaining assembly 220 which cooperates with the side wall of the tank body 201 to realize the adjustability of the position of the first pipe body 212 along its axial direction and the retention of a certain adjusted state. By changing the height position of the first pipe body 212 in the overflow tank 202, the height of the overflow water outlet can be adjusted, so that the height of the cooling water in the tank body 201 can be adjusted, which is convenient for water bath cooling during the formation of batteries of different sizes.

[0062] Fig. 5 shows a structural schematic diagram of the retaining assembly 220, which has a connecting part 221 and a cantilever 222 fixed with the connecting part 221. The connecting part 221 is fixed with the first pipe body 212, so that the first pipe body 212 can change its position with the cantilever 222. Fig. 6 shows a partial enlarged view of A in Fig. 3, that is, a schematic diagram of the cooperation state of the cantilever 222 and the tank body 201. The side wall of the tank body 201 is provided with a first slot 205, and the cantilever 222 extends into the tank body 201 through the first slot 205. The cantilever 222 can move in the first slot 205 to change the height of the first pipe body 212. When the cantilever 222 is locked in position relative to the first slot 205, the height position of the first pipe body 212 is maintained.

[0063] In some specific embodiments, the connecting portion 221 is arranged in a ring shape and is fixed to the first pipe body 212, for example, by welding or by a clamp.

[0064] In some other specific embodiments, the connecting portion 221 is arranged in an arc shape, including a superior arc, an inferior arc and a semicircular arc. In this case, the connecting portion 221 is usually fixed to the first pipe body 212 by welding.

[0065] In some other specific embodiments, the connecting portion 221 can even be arranged at one end of the cantilever 222 and is fixed to the first pipe body 212 only by the end. In this case, the end of the cantilever 222 is usually fixed to the first pipe body 212 by welding.

[0066] FIG. 7 shows a schematic view of the internal structure of the cantilever 222. For the convenience of illustration and description, the cantilever 222 is partially cut away in FIG. 7. The cantilever 222 has a strip-shaped cavity 223. As shown in FIG. 5, the cantilever 222 has openings 227 on both sides for communicating with the cavity 223. The cavity 223 is provided with an elastic sheet 224 and a contact sheet 225.

[0067] The elastic sheet 224 has a fixed end and a free end. The fixed end is fixed to the inner wall of the cavity 223 and is close to the connecting portion 221. The free end is provided with a counterweight 226.

[0068] The contact sheet 225 is arranged at the opening 227, as shown in FIG. 8. The contact sheet 225 includes a first connecting sheet 225a and second, third and fourth connecting sheets 225b, 225c and 225d symmetrically arranged on both sides of the first connecting sheet 225a. The first connecting sheet 225a, the second connecting sheet 225b and the third connecting sheet 225c are sequentially connected. The second connecting sheet 225b can be flipped relative to the first connecting sheet 225a. The third connecting sheet 225c can also be flipped relative to the second connecting sheet 225b. The fourth connecting sheet 225d is arranged on the side wall of the second connecting sheet 225b and is inwardly and obliquely arranged. The oblique direction is upward away from the fourth connecting sheet 225d. The elastic sheet 224 is pressed against the third connecting sheet 225c by the counterweight 226, so that the second connecting sheet 225b and the third connecting sheet 225c are kept in the cavity 223.

[0069] As shown in Fig. 6, the two side walls of the first strip-shaped hole 205 are provided with continuous tooth grooves. When the cantilever 222 is arranged at the bottommost position of the first strip-shaped hole 205, an external force is applied to the cantilever 222 to make the cantilever 222 move upward along the first strip-shaped hole 205 rapidly and stop suddenly under control. The spring piece 224 and the counterweight 226 in the cantilever 222 continue to jump upward in the cavity 223, which on one hand releases the third connecting piece 225c from the pressed state, and on the other hand makes the spring piece 224 contact the fourth connecting piece 225d and press the second connecting piece 225b out of the opening 227 in the process of pressing the fourth connecting piece 225d. The part of the second connecting piece 225b extending out of the cantilever 222 enters the tooth groove, so that the second connecting piece 225b and the tooth groove form a reverse-stopping structure to limit the cantilever 222 from falling back along the first strip-shaped hole 205, thereby keeping the position of the cantilever 222 in the first strip-shaped hole 205. The reverse-stopping structure of the second connecting piece 225b and the tooth groove is shown in Fig. 9.

[0070] Fig. 10 shows the reset structure of the cantilever 222. The bottom of the cantilever 222 is provided with a through hole 228 communicating with the cavity 223, and the bottom of the counterweight 226 is provided with a pressing part 229 extending to the outside through the through hole 228. As shown in Fig. 9, when it is needed to reset the cantilever 222 to the bottommost position, the spring piece 224 is lifted by pressing the pressing part 229, the cantilever 222 is lifted upward, the second connecting piece 225b is pressed into the cavity 223 by the tooth groove, and then the pressing part 229 is released to press the third connecting piece 225c, so that the reverse-stopping structure of the second connecting piece 225b and the tooth groove is released, and the cantilever 222 is reset.

[0071] Fig. 11 shows the structure for maintaining the stability of the cantilever 222. The side wall of the groove body 201 is provided with a sliding groove 230, and the two sides of the cantilever 222 are provided with sliding blocks 231 sliding in the sliding groove 230. The sliding groove 230 and the sliding block 231 limit the movement of the cantilever 222 to the extension direction of the sliding groove 230, thereby ensuring the stability of the first pipe body 212 during the adjustment of the overflow port height.

[0072] In addition, the embodiment also provides a control method matched with the above-mentioned multi-layer battery charging automatic transfer cooling system, which comprises the following steps:

[0073] Adjusting the overflow port height of the water bath assembly according to the size of the battery;

[0074] After the battery is injected with acid, the battery is sent into the water bath assembly for internal formation by the transfer assembly;

[0075] The battery after the formation is unloaded by the transfer assembly.

[0076] In the above steps, the specific method for uniformly adjusting the height of the overflow port of the water bath assembly according to the size of the battery is as follows:

[0077] Take a battery to be formed as a sample, and fix the magnetic assembly on the battery, and the fixed height of the magnetic assembly on the battery shell is the target height of the overflow port adjustment;

[0078] Move the sample battery with the fixed magnetic assembly from one end of the water bath tank 200 to the other end through the conveying roller 203. When the sample battery passes through the overflow tank 202, the magnetic assembly triggers the magnetic adsorption of the cantilever 222, so that the cantilever 222 accelerates upward until the cantilever 222 contacts and collides with the magnetic assembly. At the moment when the cantilever 222 contacts and collides with the magnetic assembly, the action of the spring sheet 224 and the contact sheet 225 is triggered, so that the second connecting sheet 225b and the tooth groove form a reverse structure, maintaining the cantilever 222 at the collision position, that is, the height adjustment of the overflow port is realized.

[0079] Continue to move the sample battery until all the overflow ports are adjusted to the target height.

[0080] In the above method for adjusting the height of the overflow port of the water bath assembly, in response to the magnetic assembly, the cantilever 222 should be made of a material with magnetic adsorption properties, or internally coated with a block-shaped body with magnetic adsorption properties.

[0081] As shown in FIG. 12, the magnetic assembly includes four angular clamping parts 401, four magnetic blocks 402 and four first springs 403. The magnetic blocks 402 are fixed on the angular clamping parts 401, and the first springs 403 are connected to the angular clamping parts 401 alternately at the head and tail, thereby forming a closed ring structure. When adjusting, the magnetic assembly is sleeved on the outside of the battery shell, and the compression force generated by the stretching of the first spring 403 fixes the magnetic assembly at a certain height of the battery shell. This height position is the overflow height of the cooling water in the water bath tank 200.

[0082] Embodiment 2

[0083] Based on the basis of Embodiment 1, this embodiment further improves and adds an adjustment assembly for replacing the adjustment mode of the sample battery cooperating with the magnetic assembly, so as to further improve the efficiency and convenience of adjustment.

[0087] The height of the overflow port is determined according to the size of the battery to be formed, and the position of the magnetic block 503 on the sliding seat 502 is adjusted;

[0088] The sliding seat 502 is moved along the guide rod 501 from one end to the other end of the groove 201, and when it slides over the cantilever 222, the second connecting piece 225b triggers the reverse stop structure formed by the tooth groove, and the adjustment is completed;

[0089] The cooling water is filled into the groove 201 through the circulating water distribution pipe 204;

[0092] Generally, before adjusting the height of the overflow port, the cantilever 222 is reset to the lowest position, and the cantilever 222 is limited by extending the limiting pin 512 out of the first bar-shaped hole 20; when the sliding seat 502 moves along the guide rod 501, the push plate 513 is located on the front side of the moving direction, the push plate 513 first contacts the limiting pin 512 and continuously pushes the limiting pin 512 out of the first bar-shaped hole 20 with the sliding seat 502, until the limiting pin 512 contacts the cantilever 222, at this time the magnetic block 503 is located directly above the cantilever 222, and the cantilever 222 can be quickly moved upward and contacted with the magnetic block 503 to realize the locking and positioning of the cantilever 222.

[0094] Figure 15 shows a schematic diagram of the connection structure of the connecting bracket 511 and the limiting pin 512. The connecting bracket 511 has a second strip-shaped hole 514, and a part of the limiting pin 512 is slidably arranged in the second strip-shaped hole 514. The bottom of the connecting bracket 511 is provided with a second spring 515, one end of the second spring 515 abuts or is fixed to the connecting bracket 511, and the other end abuts or is fixed to the limiting pin 512. The head of the limiting pin 512 is provided with an inclined surface. When the cantilever 222 is reset, the inclined surface of the limiting pin 512 cooperates with the cantilever 222, so that the limiting pin 512 moves along the second strip-shaped hole 514 and compresses the second spring 515, until the cantilever 222 slides past the limiting pin 512, and the second spring 515 is elongated again to drive the limiting pin 512 to reset.

[0095] Figure 16 shows a schematic diagram of the structure of the limiting pin 512 cooperating with the push plate 513. The limiting pin 512 is provided with an insert plate 516 that can vertically slide. The top of the connecting bracket 511 is provided with a stepped groove 517, and the stepped groove 517 coincides with the second strip-shaped hole 514. The stepped groove 517 is shorter than the second strip-shaped hole 514, and is arranged on the side away from the first strip-shaped hole 20. When the insert plate 516 is in the part of the stepped groove 517, the insert plate 516 slides downward by a distance, so that the part of the limiting pin 512 exposed is retracted into the limiting pin 512.

[0096] When the push plate 513 moves with the sliding seat 502, the push plate 513 first contacts the insert plate 516 and drives the limiting pin 512 to move, until the limiting pin 512 moves out of the first strip-shaped hole 20, the restriction on the cantilever 222 is released, and then moves a small distance to enter the stepped groove 517. The insert plate 516 slides into the stepped groove 517 and is separated from the push plate 513, so that the sliding seat 502 can continue to move along the guide rod 501.

[0097] The end of the stepped groove 517 is further provided with a slope surface 518, which is arranged on the side facing the first strip-shaped hole 20, so that when the limiting pin 512 is reset, the push plate 513 can be lifted with the cooperation of the slope surface 518.

[0098] When the insert plate 516 is about to enter the stepped groove 517, in order to facilitate the insert plate 516 to slide into the stepped groove 517, the contact surfaces of the insert plate 516 and the push plate 513 can be provided with inclined surfaces, or one of the insert plate 516 and the push plate 513 is provided with an inclined surface, so that the horizontal pressure generated by the movement of the push plate 513 can be converted into vertical pressure on the insert plate 516, facilitating the insert plate 516 to be pressed into the limiting pin 512 and separated from the push plate 513.

[0099] The above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto.
