Description

Technical Field

[0001] The present invention belongs to the technical field of new energy battery production, and in particular relates to a multi-layer battery charging automatic transfer cooling system and a control method. Background Art

[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 acid injection. After acid injection, the battery needs to be placed in a water tank for cooling immediately, because sulfuric acid immediately reacts with the active substances inside the battery, generating a large amount of heat energy. If it is not cooled or the cooling temperature is not enough, it will cause the decomposition of the active substances inside the battery and affect the performance of the battery. Therefore, a water bath needs to be used for water bath cooling when the battery is internally formed.

[0003] In the current era of rapid development of industrial automation, in order to improve the efficiency of transfer cooling during the battery formation water bath process, a supporting system is also needed to solve this problem. Summary of the invention

[0004] In view of the above technical problems, this application proposes a multi-layer battery charging automatic transfer cooling system and control method. The specific technical solutions are as follows:

[0010] The side wall of the first strip-shaped hole is provided with continuous tooth grooves;

[0011] The cantilever is provided with a strip-shaped cavity and a spring sheet and a contact sheet arranged in the cavity, and both sides of the cantilever are provided with openings communicating with the cavity;

[0012] One end of the spring sheet is a fixed end, and the other end is a free end, the fixed end is close to the first tube body and fixed to the inner wall of the cavity, and a counterweight is arranged on the free end;

[0014] Under normal conditions, the elastic sheet is pressed against the third connecting sheet by the counterweight to keep the contact sheet in the cavity;

[0015] When the cantilever is subjected to an upward external force, the cantilever quickly moves upward along the first strip hole and when it stops, the spring sheet jumps in the cavity to release the third connecting piece and squeeze the fourth connecting piece, so that the second connecting piece is embedded in the tooth groove through the opening to form a non-return structure.

[0016] As a preferred embodiment of the above technical solution, a through hole connected to the cavity is provided at the bottom of the cantilever, and a pressing portion extending to the outside through the through hole is provided at the bottom of the counterweight, and the pressing portion is pressed to lift the spring sheet and lift the cantilever at the same time, and the second connection is squeezed into the cavity by the tooth groove, and the third connection piece slides under the spring sheet to reset.

[0017] As a preferred embodiment of the above technical solution, a slide groove is arranged on the side wall of the water bath, and a sliding block sliding in the slide groove is arranged on the side of the cantilever.

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0048] Example 1

[0049] Figure 1 Shown is a plan view of a multi-layer battery charging automatic transfer and cooling system, which includes a transfer component and a water bath component when viewed from a plan view. The water bath assembly is configured to have a plurality of parallel water baths 200, the number of which is determined according to actual production needs. The water bath 200 is used to place batteries that need to be charged and formed, and a certain amount of circulating water is filled into the water bath 200 to immerse the lower part of the battery to achieve the purpose of cooling. The transfer assembly is used to transport the batteries in a matching manner to improve the efficiency of battery transportation. The transfer assembly includes a first conveying chain plate 102, a first elevator 103, and a second conveying chain plate 104, wherein the first conveying chain plate 102 is used to connect the acid filling machine 101 with the first elevator 103, so as to realize that the acid-filled batteries are transferred to the first elevator 103 through the first conveying chain plate 102, and are lifted to the upper layer by the first elevator 103 according to needs or directly transported to the corresponding water bath 200 through the second conveying chain plate 104, and placed in the water bath 200 by the operator for battery internal formation.

[0050] In the above technical solution, the water bath 200 is arranged in at least two layers to increase the number of water baths 200 on the same floor space, thereby improving production efficiency. The first elevator 103 is arranged to transfer the batteries between the bottom layer and the upper layer.

[0051] Of course, in other embodiments, the water bath 200 is provided as only one layer. In this state, the first elevator 103 can be removed accordingly, and only the second conveying chain plate 104 is connected to the acid filling machine 101 .

[0052] The first conveying chain plate 102 in the transfer assembly has no special restrictions, but the second conveying chain plate 104 should be subject to certain position restrictions, see Figure 1 Due to the requirements of systematic management and layout, the water baths 200 are usually arranged in parallel with each other. Therefore, the second conveyor chain plate 104 should be arranged at the end of the water bath 200 and extend along the direction in which the water bath 200 is arranged in parallel to ensure that the second conveyor chain plate 104 can convey the battery to the position of each water bath 200.

[0053] In other embodiments, a second elevator 105 is also provided in the transfer assembly. Relative to the first elevator 103, the second elevator 105 is provided at the other end of the second conveying chain plate 104 to facilitate the transfer of the batteries on the second floor and above that have completed internalization to the ground for subsequent operations.

[0054] In order to further improve production efficiency, two second conveying chain plates 104 are provided, and the two second conveying chain plates 104 are respectively provided at both ends of the water bath 200, wherein one second conveying chain plate 104 is connected to the first elevator 103, and is only used for conveying and transferring batteries to be internalized, and the other second conveying chain plate 104 is connected to the second elevator 105, and is only used for conveying and transferring batteries that have completed internalization.

[0055] Figure 2 The structure diagram of the fixed installation of the water bath 200 is shown. The water bath 200 is installed on the steel frame 301 by bolt fastening and welding. The steel frame 301 is formed by splicing and fixing channel steel, angle steel, I-beam or square steel, and an extended working platform 302 is formed on the side of the steel frame 301 for operators to walk on.

[0056] Figure 3 What is shown is a schematic diagram of the structure of a water bath 200, which includes a tank body 201, an overflow tank 202, a conveying roller 203 and a circulating water distribution pipe 204, wherein the tank body 201 is configured as a long strip tank with an opening at the top, the overflow tank 202 is arranged on the side of the tank body 201, and the conveying rollers 203 are installed inside the tank body 201 and are arranged at intervals along the length direction of the tank body 201. The conveying rollers 203 can be used to more conveniently transport batteries in the tank body 201. The circulating water distribution pipe 204 has a portion extending into the tank body 201 and continuously replenishes water into the tank body 201. The overflow tank 202 is used to maintain the liquid level in the tank body 201 to ensure that the lower half of the battery is immersed in water. At the same time, it cooperates with the circulating water distribution pipe 204 to achieve the purpose of water circulation in the tank body 201, ensuring that the water in the tank body 201 meets its cooling demand.

[0057] The overflow groove 202 serves as a structure for maintaining the liquid level in the tank body 201. A notch 204 is provided at the connection between the overflow groove 202 and the tank body 201. The notch 204 connects the overflow groove 202 with the tank body 201. Usually, the overflow groove 202 is directly welded and fixed to the side wall of the tank body 201 to ensure the sealing of the weld. The notch 204 can be directly provided on the tank body 201. An overflow pipe assembly is provided in the overflow groove 202. The height of the upper port of the overflow pipe assembly determines the liquid level in the tank body 201.

[0058] Figure 4 What is shown is a schematic diagram of the structure of the overflow pipe assembly, which includes a main drainage pipe 211 and a first tube body 212, a second tube body 213 and a third tube body 214 connected to the main drainage pipe 211. The first tube body 212, the second tube body 213 and the third tube body 214 constitute a complete overflow pipe. The number of overflow pipes is set according to the overflow groove 202, that is, at least one overflow pipe is arranged in each overflow groove 202, and they are uniformly connected to the main drainage pipe 211.

[0059] The first tube body 212 as an overflow pipe structure is arranged to be movable in the overflow groove 202 to change the height position of the top opening of the first tube body 212, so that the water in the groove body 201 can be discharged through the top opening of the first tube body 212; the third tube body 214 is fixed at the bottom of the overflow groove 202, and the third tube body 214 extends through the overflow groove 202 to the outside to communicate with the main drainage pipe 211, and the connection between the third tube body 214 and the overflow groove 202 should also ensure sealing; the second tube body 213 is used to connect the first tube body 212 and the third tube body 214. The second tube body 213 is arranged as a flexible tube to adapt to the need of changing the position state of the first tube body 212 and ensure the connectivity between the first tube body 212 and the third tube body 214.

[0060] Generally speaking, lead-acid batteries are provided with shells of different sizes according to the difference in capacity. For example, the more common 12V / 6AH size is about 150mm*70mm*105mm, the 12V / 9AH size is about 180mm*70mm*130mm, and the 12V / 24AH size is about 280mm*70mm*200mm. If the height of the cooling water in the tank 201 is maintained at a high level and cannot be adjusted, it cannot meet the formation cooling requirements of smaller-sized batteries. If the height of the cooling water in the tank 201 is maintained at a low level and cannot be adjusted, it cannot immerse the shell of the larger-sized battery, resulting in poor cooling effect.

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

[0062] Figure 5 The structure diagram of the holding assembly 220 is shown. The holding assembly 220 has a connecting portion 221 and a cantilever 222 fixed to the connecting portion 221. The connecting portion 221 is fixed to the first tube body 212, so that the first tube body 212 can change its position along with the cantilever 222. Figure 6 It is shown that Figure 3 The partial enlarged view at point A is a schematic diagram of the matching state of the cantilever 222 and the slot body 201. A first strip hole 205 is provided on the side wall of the slot body 201, and the cantilever 222 extends into the slot body 201 through the first strip hole 205. The cantilever 222 can move in the first strip hole 205 to change the height of the first tube body 212. When the cantilever 222 is locked in position relative to the first strip hole 205, the height position of the first tube body 212 is maintained.

[0063] In some specific embodiments, the connection portion 221 is configured to be annularly nested outside the first tube body 212 and fixed to the first tube body 212, such as by welding the annular connection portion 221 to the first tube body 212, or by using a clamp to fix it to the first tube body 212.

[0064] In other specific embodiments, the connection portion 221 is configured to be an arc, including a major arc, a minor arc, and a semicircular arc. In this case, the arc-shaped connection portion 221 is usually fixed to the first tube body 212 by welding.

[0065] In other specific embodiments, the connection portion 221 can even be set as one end of the cantilever 222, and is fixed to the first tube body 212 only through this end. In this way, one end of the cantilever 222 is usually fixed to the first tube body 212 by welding.

[0066] Figure 7 The structure diagram of the cantilever 222 is shown in FIG. 2. For the convenience of illustration and description, Figure 7 The cantilever 222 is partially cut away, and there is a strip-shaped cavity 223 in the cantilever 222. Figure 5 The cantilever 222 has openings 227 on both sides thereof communicating with the cavity 223 , and a spring piece 224 and a contact piece 225 are disposed in the cavity 223 .

[0067] One end of the spring piece 224 is a fixed end, and the other end is a free end. The fixed end is fixed to the inner wall of the cavity 223 and is close to the connecting portion 221 . A counterweight 226 is disposed on the free end.

[0068] The contact piece 225 is arranged at the opening 227, and the arrangement state is as follows: Figure 8 As shown, the contact piece 225 includes a first connecting piece 225a and a second connecting piece 225b, a third connecting piece 225c and a fourth connecting piece 225d symmetrically arranged on both sides of the first connecting piece 225a. The first connecting piece 225a, the second connecting piece 225b and the third connecting piece 225c are connected in sequence, and the second connecting piece 225b can be flipped relative to the first connecting piece 225a, and the third connecting piece 225c can also be flipped relative to the second connecting piece 225b. The fourth connecting piece 225d is arranged on the side wall of the second connecting piece 225b, and the fourth connecting piece 225d is tilted inwardly, and the tilting direction is to tilt upward away from the fourth connecting piece 225d. The elastic piece 224 is pressed on the third connecting piece 225c by the action of the counterweight 226, so that the second connecting piece 225b and the third connecting piece 225c are retained in the cavity 223.

[0069] Combination Figure 6As shown in the figure, there are continuous tooth grooves on the two side walls of the first strip hole 205. When the cantilever 222 is set at the bottom of the first strip hole 205, an external force is applied to the cantilever 222, so that the cantilever 222 moves upward quickly along the first strip hole 205 and stops suddenly under control. The spring piece 224 and the counterweight 226 in the cantilever 222 continue to jump upward in the cavity 223 for a period of time, and on the one hand, they are separated from the third connecting piece 225c so that the pressure state of the third connecting piece 225c is released. On the other hand, the spring piece 224 contacts the fourth connecting piece 225d and in the process of squeezing the fourth connecting piece 225d, the second connecting piece 225b is pressed out through the opening 227, and the portion 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 non-return structure, which restricts the cantilever 222 from falling back along the first strip hole 205 again, thereby maintaining the position of the cantilever 222 in the first strip hole 205. The second connecting piece 225b and the tooth groove form a non-return structure as shown in FIG. Fig. 9 shown.

[0070] Fig.10 The figure 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. The bottom of the counterweight 226 is provided with a pressing portion 229 extending to the outside through the through hole 228. Fig. 9 When the cantilever 222 needs to be reset to the bottom, the pressing portion 229 is pressed to lift the spring piece 224, and then the cantilever 222 is lifted upward, so that the second connecting piece 225b is squeezed into the cavity 223 by the tooth groove, and then the pressing portion 229 is released so that the pressing portion 229 presses the third connecting piece 225c, so that the second connecting piece 225b and the tooth groove can form a non-return structure, and the cantilever 222 is reset.

[0071] Fig.11 What is shown is a structure for maintaining the stability of the cantilever 222. A slide groove 230 is provided on the side wall of the trough body 201, and sliders 231 sliding in the slide groove 230 are provided on both sides of the cantilever 222. The slide groove 230 and the slider 231 limit the cantilever 222 to move only along the extension direction of the slide groove 230, thereby ensuring the stability of the first tube body 212 during the process of adjusting the overflow port height.

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

[0073] Adjust the overflow height of the water bath assembly uniformly according to the battery size;

[0074] After the battery is filled with acid, it is sent to the water bath assembly through the transfer assembly for internalization;

[0075] The formed battery is unloaded through the transfer assembly.

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

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

[0078] The sample battery with the magnetic component fixed thereon is moved from one end of the water bath 200 to the other end through the conveying roller 203. When the sample battery passes through the overflow tank 202, the magnetic component triggers the magnetic adsorption effect on the cantilever 222, causing the cantilever 222 to rise faster until the cantilever 222 contacts and collides with the magnetic component. At the moment when the cantilever 222 contacts and collides with the magnetic component, the spring 224 and the contact piece 225 are triggered to move, so that the second connecting piece 225b and the tooth groove form a non-return structure, maintaining the cantilever 222 in the collision position, that is, realizing the height adjustment of the overflow port;

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

[0080] In the above method for adjusting the overflow height of the water bath component, in order to respond to the magnetic attraction component, the cantilever 222 should be set to a material with magnetic adsorption properties, or be coated with a block with magnetic adsorption properties.

[0081] Fig.12 What is shown in the figure is a schematic diagram of the structure of the magnetic attraction component, which includes an angular clamping part 401, a magnetic block 402 and a first spring 403. Four angular clamping parts 401, four magnetic blocks 402 and four first springs 403 are provided. The magnetic block 40 is fixed on the angular clamping part 401. The first spring 403 and the angular clamping part 401 are alternately connected end to end to form a closed annular structure. When adjusting, the magnetic attraction component is put on the outside of the battery shell, and the magnetic attraction component is fixed at a certain height of the battery shell through the compression force generated by the stretching of the first spring 403. The height position is the overflow height of the cooling water in the water bath 200.

[0082] Example 2

[0083] This embodiment is based on the first embodiment, and further improves and adds an adjustment component, which is used to replace the adjustment method of the sample battery and the magnetic attraction component to further improve the efficiency and convenience of the adjustment.

[0084] Fig.13 What is shown is a schematic diagram of the structure of the adjustment component, which includes a guide rod 501, a sliding seat 502, and a magnetic block 503. Both ends of the guide rod 501 are fixed on the side walls of the groove body 201, the sliding seat 502 is slidably set on the guide rod 501, and the magnetic block 503 is installed on the sliding seat 502, and the height position of the sliding seat 502 can be adjusted.

[0085] A control method for realizing a multi-layer battery charging automatic transfer cooling system based on the regulating component includes the following steps:

[0086] Drain the cooling water in the tank 201 through the drain valve;

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

[0088] The sliding seat 502 moves along the guide rod 501 from one end of the slot body 201 to the other end, and when sliding over the cantilever 222, the second connecting piece 225b is triggered to form a non-return structure with the tooth groove, thereby completing the adjustment;

[0089] Cooling water is charged into the tank body 201 through the circulating water distribution pipe 204;

[0090] The battery to be formed is placed in the tank 201, powered on to start the formation, and taken out after the formation is completed.

[0091] Fig.13 An auxiliary component is also shown, which includes a connecting bracket 511, a limit pin 512 and a push plate 513. The connecting bracket 511 is fixed on the inner wall of the groove body 201, the limit pin 512 is installed on the connecting bracket 511 and can slide along the connecting bracket 511 to change the positional relationship with the first strip hole 205, and the push plate 513 is fixed on the side wall of the sliding seat 502 and moves with the sliding seat 502.

[0092] Usually, before adjusting the height of the overflow port, the cantilever 222 is reset to the lowest position, and the cantilever 222 is restricted by extending the limit pin 512 out of the first strip hole 20; when the sliding seat 502 moves along the guide rod 501, the push plate 513 is located at the front side of the moving direction, and the push plate 513 first contacts the limit pin 512 and continues to press the limit pin 512 out of the first strip hole 20 as the sliding seat 502 moves until the limit pin 512 restricts the contact with the cantilever 222. At this time, the magnetic block 503 is located directly above the cantilever 222, and the cantilever 222 can be forced to move upward quickly and contact the magnetic block 503 to collide, thereby locking and positioning the cantilever 222.

[0093] Fig.14 What is shown is a schematic diagram of the connection structure between the sliding seat 502 and the magnetic block 503. A screw rod 504 is arranged inside the sliding seat 502 to cooperate with a nut fixed inside the magnetic block 503, and a motor (not shown in the figure) is fixed at the end of the sliding seat 502 and connected to the screw rod 504 to drive the screw rod 504 to rotate, thereby achieving the purpose of adjusting the position of the magnetic block 503.

[0094] Fig.15What is shown is a schematic diagram of the connection structure between the connecting bracket 511 and the limit pin 512, the connecting bracket 511 has a second strip hole 514, the limit pin 512 is partially slidably arranged in the second strip hole 514, and a second spring 515 is arranged at the bottom of the connecting bracket 511, one end of the second spring 515 is abutted against or fixed to the connecting bracket 511, and the other end is abutted against or fixed to the limit pin 512, and the head of the limit pin 512 is arranged as an inclined surface, and when the cantilever 222 is reset, it cooperates with the inclined surface of the limit pin 512, so that the limit pin 512 moves along the second strip hole 514 to squeeze the second spring 515, until the cantilever 222 slides over the limit pin 512, and the second spring 515 extends again to drive the limit pin 512 to reset.

[0095] Fig.16 What is shown is a schematic diagram of the structure of the limit pin 512 cooperating with the push plate 513. A plug plate 516 that can slide vertically is arranged on the limit pin 512. A step groove 517 is arranged on the top of the connecting bracket 511, and the step groove 517 coincides with the second strip hole 514. The step groove 517 is shorter than the second strip hole 514, and the step groove 517 is arranged on the side away from the first strip hole 20. When the plug plate 516 is in the part without the step groove 517, it is resisted by the surface of the connecting bracket 511 and the top of the limit pin 512 is exposed. When the plug plate 516 is in the part with the step groove 517, it will slide down for a distance and retract the part of the limit pin 512 exposed into the limit pin 512.

[0096] When the push plate 513 moves with the sliding seat 502, the push plate 513 will first contact the plug plate 516 and drive the limit pin 512 to move until the limit pin 512 moves out of the first strip hole 20, releasing the restriction on the cantilever 222, and then enters the step groove 517 after moving a short distance. The plug plate 516 will slide into the step groove 517 and disengage from the push plate 513, and the sliding seat 502 can continue to move along the guide rod 501.

[0097] A slope 518 is also provided at the end of the step groove 517 . The slope 518 is provided on the side facing the first strip hole 20 , so that when the limiting pin 512 is reset, the push plate 513 can be lifted with the cooperation of the slope 518 .

[0098] When the plug plate 516 is about to enter the step groove 517, in order to facilitate the plug plate 516 to slide into the step groove 517, the contact surfaces of the plug plate 516 and the push plate 513 can be set as inclined surfaces, or one of the plug plate 516 and the push plate 513 can be set as 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 plug plate 516, so as to facilitate pressing the plug plate 516 into the limit pin 512 and disengaging from the push plate 513.

[0099] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
