Description

Technical Field

[0001] This invention relates to battery manufacturing technology, and more particularly to an acid-adding system for valve-regulated automated lead-acid batteries. Background Technology

[0002] Lead-acid batteries require internal acid filling during production to ensure normal operation. Traditionally, this is done manually. However, sulfuric acid is a highly corrosive and hazardous substance, and during manual acid filling, it is prone to splashing, causing harm to people and the environment.

[0003] Other batteries consist of multiple cells, each a separate space. Each cell contains a single acid tank. Because the amount of acid added is manually controlled, the amount in each cell varies, making it impossible to guarantee battery consistency and resulting in low work efficiency.

[0004] In today's highly competitive market, the requirements for battery performance are becoming increasingly stringent, demanding better consistency and more convenient, faster, and more efficient use. Therefore, an automated acid filling system is needed to ensure consistent acid injection volume in each individual acid tank during the process. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention proposes a valve-regulated automated lead-acid battery acid-adding system.

[0006] The technical solution of this invention is implemented as follows:

[0007] A valve-regulated automated lead-acid battery acid-adding system, characterized in that it comprises:

[0008] The system comprises multiple conveyor mechanisms, including a first conveyor belt and a second conveyor belt at the same height. The first conveyor belt transports batteries requiring acid replenishment to a designated location, while the second conveyor belt transfers batteries from the first conveyor belt that have already undergone acid replenishment. The first and second conveyor belts travel in opposite directions.

[0009] An acid injection mechanism cooperating with a conveying mechanism includes an acid injection tank, a base, a seal, and an acid injection head. The base is installed at the lower end of the acid injection tank. The seal and the acid injection head are connected and installed on the base. An injection chamber is formed in the middle of the base. The injection chamber has a first inner wall and a second inner wall, which are connected by a bottom wall. The bottom wall slopes downward from the first inner wall to the second inner wall. The bottom wall has multiple movable holes, and a telescopic member is located in the middle of each movable hole. The acid injection head is located inside the telescopic member.

[0010] The sealing element consists of a sealing plate and symmetrically arranged blocks on the sealing plate, with limiting grooves formed between the blocks. A baffle is located in the middle of the acid injection tank, and a positioning post is provided at the lower end of the baffle. An elastic element is fitted onto the positioning post, with its upper end contacting the lower surface of the baffle and its lower end located within the limiting groove. The lower end of the sealing element has a threaded hole and an injection port, connected by an injection channel. The lower surface of the sealing element is kept in contact with the bottom wall by the elastic force of the elastic element.

[0011] The acid injection head consists of a threaded part, a mounting body, and a contact body from top to bottom. The threaded part has a hollow center to form a countersunk hole. The threaded part is installed in conjunction with the threaded hole. The threaded part has a connection port that communicates with the countersunk hole. When the threaded part is installed in the threaded hole, the connection port is kept in communication with the injection port through the injection channel. The mounting body and the contact body form a through hole that communicates with the countersunk hole. When the acid injection head is installed, the telescopic component is pushed to extend.

[0012] In this invention, the battery is provided with an injection head, the injection head has a hollowed-out center forming an injection hole, and the outside is provided with threads. The injection head is provided with a notch, and the notch is kept in the direction of movement toward the first conveyor belt.

[0013] In this invention, a first plane is provided on the notch, and the height of the first plane is lower than that of the acid injection head.

[0014] In this invention, the mounting body is provided with symmetrically arranged recesses, and a second plane is provided in the recesses.

[0015] In this invention, a first limiting point is formed at the connection between the first inner wall and the bottom wall, and a second limiting point is formed at the connection between the second inner wall and the bottom wall. The sealing element is located between the first limiting point and the second limiting point.

[0016] In this invention, the center lines of the movable hole, the telescopic member, and the acid injection head coincide and are all perpendicular to the bottom wall. There is an angle H between the center line of the positioning post and the center line of the acid injection head.

[0017] In this invention, the telescopic component is composed of a first connecting part, a first arc-shaped part, a second arc-shaped part, a second connecting part, a telescopic cylinder, a third arc-shaped part, and a cylindrical part. An installation chamber is formed in the middle of the telescopic cylinder, and an opening and closing area is formed between the first arc-shaped part and the second arc-shaped part.

[0018] In this invention, the telescopic cylinder is provided with multiple pleats. When the acid injection head is installed in the installation chamber, the telescopic cylinder is pushed by the acid injection head to straighten the pleats.

[0019] In this invention, the telescopic cylinder has an annular protrusion inside, and the lower end of the mounting body has an annular recess that mates with the annular protrusion.

[0020] In this invention, the cylindrical part has a hollowed-out middle section to form a deformation chamber, the lower end of the cylindrical part has a through-hole, the contact body is disposed inside the cylindrical part, the lower end of the contact body has an arc-shaped part, the arc-shaped part opens the through-hole, and the cylindrical part is wrapped around the arc-shaped part.

[0021] The valve-regulated automated lead-acid battery acid filling system of this invention has the following beneficial effects: The valve-regulated automated lead-acid battery acid filling system transports the battery through a first conveyor belt. Under the power of the first conveyor belt, the battery pushes the acid filling head to rotate the sealing element at a certain angle, thereby realizing automatic acid filling. This not only automates the operation and reduces the participation rate of personnel, but also ensures that the acid filling amount of each acid tank is consistent, which is conducive to improving the service life of the entire battery and accelerating the acid filling efficiency.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] like Figures 1 to 17As shown, this valve-regulated automated lead-acid battery acid-adding system of the present invention includes a conveying mechanism 1 and an acid-adding mechanism 2. The conveying mechanism 1 is used to transfer batteries 3 that need acid addition and batteries 3 that have already been acid-added. The acid-adding mechanism 2 is located at the upper end of the conveying mechanism 1. When the conveying mechanism 1 transports the battery 3 that needs acid addition to the lower end of the acid-adding mechanism 2, the acid-adding head 5 located in the acid-adding mechanism 2 can be displaced by the injection head 4 on the battery 3 under the power of the conveying mechanism 1, thereby opening the acid-adding head 5. The acidic liquid flowing out from the acid-adding head 5 will then enter the battery 3 from the injection head 4.

[0042] To meet the needs of actual production processes, multiple conveying mechanisms 1 and multiple acid injection heads 5 that cooperate with the conveying mechanisms 1 can be set up, thereby improving the acid injection efficiency of the battery 3, accelerating production, and meeting market demands. Furthermore, improvements can be made for different models of batteries 3 by increasing the number of acid injection heads 5 on a single sealing element 17, facilitating uniform acid injection into individual acid tanks. This ensures that the acidic liquid in different acid tanks within the same battery 3 is consistent, effectively improving acid injection efficiency and extending the service life of the battery 3.

[0043] The conveying mechanism 1 has multiple sets, which can be arranged according to actual production requirements. The conveying mechanism 1 has a first conveyor belt 6 and a second conveyor belt 7. The first conveyor belt 6 is located directly below the acid injection head 5, while the second conveyor belt 7 is located next to the first conveyor belt 6. There is a gap between the first conveyor belt 6 and the second conveyor belt 7. The distance of this gap cannot exceed one-third of the width of the battery 3, so as to facilitate the transfer of the battery 3 from the first conveyor belt 6 to the second conveyor belt 7.

[0044] The first conveyor belt 6 and the second conveyor belt 7 are at the same height, or the second conveyor belt 7 can be positioned slightly lower than the first conveyor belt 6, thus facilitating the transfer of the batteries 3 from the first conveyor belt 6 to the second conveyor belt 7. The first conveyor belt 6 transports the batteries 3 requiring acid filling to the designated location, and the second conveyor belt 7 transfers the batteries 3 that have been filled with acid from the first conveyor belt 6. The first conveyor belt 6 and the second conveyor belt 7 move in opposite directions.

[0045] Furthermore, a fixed plate 8 is provided in the conveying mechanism 1, and symmetrically arranged push plates 9 are provided on the fixed plate 8, which are located above the first conveyor belt 6. A fixed area is formed in the middle of the symmetrically arranged push plates 9. After the battery 3 is conveyed to the fixed area by the first conveyor belt 6, the battery 3 is blocked by the fixed plate 8, so that the first conveyor belt 6 stops moving. At this time, the injection head 4 can push the acid injection head 5 to change position, thus realizing acid injection.

[0046] After the acid injection is completed, a cylinder can be installed at one end of the fixed plate 8 to push the fixed plate 8, so that the fixed plate 8 drives the push plate 9 to push the battery 3 located in the fixed area onto the second conveyor belt 7.

[0047] Of course, during acid injection, the amount of acid to be injected is determined by calculating a certain time. If it is necessary to stop acid injection, the first conveyor belt 6 needs to be activated, causing it to reverse and drive the battery 3 a certain distance. The length of this distance needs to be greater than the diameter of the injection head 4, keeping the injection head 5 out of the injection head 4, thereby stopping the acid injection. Then, the cylinder can be activated, pushing the fixing plate 8 to transfer the battery 3 from the first conveyor belt 6 to the second conveyor belt 7, where it is transported to the designated position.

[0048] The battery 3 is equipped with an injection head 4, which has a hollowed-out injection hole 10 in the middle and is threaded on the outside. The injection head 4 has a notch 12, which faces the direction of movement of the first conveyor belt 6. The notch 12 has a first flat surface 13, which is lower than the acid injection head 5. When the injection head 4 pushes the acid injection head 5, it contacts the arcuate portion 14 of the acid injection head 5 through the inner wall of the injection head 4.

[0049] The acid injection mechanism 2 includes an acid injection box 15, a base 16, a sealing element 17, and an acid injection head 5. The acid injection mechanism 2 can achieve rapid acid injection and simultaneous acid injection from multiple acid injection heads 5, and can perform acid injection work without the need for additional external force drive.

[0050] The acid injection tank 15 can be an open tank 18 or a closed tank 18. The acid injection tank 15 consists of an annular tank wall 19 and a first fixing body 20. The first fixing body 20 is located at the lower end of the annular tank wall 19 and is used to connect with the base 16. A liquid storage chamber 21 is formed in the middle of the annular tank wall 19.

[0051] The base 16 is installed at the lower end of the acid injection tank 15. The seal 17 is connected to and installed on the acid injection head 5. An injection chamber 22 is formed in the middle of the base 16. The base 16 consists of an annular body 23 and a second fixed body 24, with the second fixed body 24 located at the upper end of the annular body 23.

[0052] The injection chamber 22 is provided with a first inner wall 25 and a second inner wall 26, which are connected by a bottom wall 27. The bottom wall 27 is inclined downward from the first inner wall 25 toward the second inner wall 26. The bottom wall 27 is provided with multiple holes 28, and a telescopic member 29 is provided in the middle of the movable hole 28. The acid injection head 5 is located in the telescopic member 29.

[0053] A pressure-applying part 30 is provided inside the annular box wall 19. A pressure-applying body 31 is provided on the bottom surface of the pressure-applying part 30. An annular groove 32 is provided on the annular body 23 to cooperate with the pressure-applying body 31. A sealing ring 33 is provided in the annular groove 32. The pressure-applying body 31 squeezes the sealing ring 33 into the annular groove 32. Furthermore, the first fixing body 20 and the second fixing body 24 are fixed together by bolts, which can prevent leakage between the acid injection box 15 and the base 16.

[0054] The sealing element 17 consists of a sealing plate 34 and symmetrically arranged blocks 35 on the sealing plate 34, with a limiting groove 36 formed between the blocks 35. A baffle 37 is provided in the middle of the acid injection tank 15, and a positioning post 38 is provided at the lower end of the baffle 37. An elastic element 39 is sleeved on the positioning post 38, with the upper end of the elastic element 39 contacting the lower surface of the baffle 37 and the lower end located in the limiting groove 36.

[0055] Because the bottom wall 27 is inclined, the seal 17 is also inclined when it is installed on the bottom wall 27. However, the positioning post 38 is installed vertically, so the lower end of the elastic member 39 remains inclined. Furthermore, the elastic member 39 is in a compressed state, ensuring that the bottom surface of the seal 17 is tightly fitted to the bottom wall 27, preventing liquid leakage.

[0056] The lower end of the seal 17 is provided with a threaded hole 40 and an injection port 41. The threaded hole 40 and the injection port 41 are connected by an injection channel 42. The lower surface of the seal 17 is kept in contact with the bottom wall 27 by the elastic force of the elastic member 39. When the seal 17 is separated from the bottom wall 27, the liquid enters the injection port 41 from the second inner wall 26.

[0057] A first limiting point 43 is formed at the connection between the first inner wall 25 and the bottom wall 27, and a second limiting point 44 is formed at the connection between the second inner wall 26 and the bottom wall 27. The sealing member 17 is located between the first limiting point 43 and the second limiting point 44. When the end in contact with the second limiting point 44 is opened, the end in contact with the first limiting point 43 rotates, causing the center line of the acid injection head 5 to coincide with the center line of the positioning post 38.

[0058] The centerlines of the movable hole 28, the telescopic member 29, and the acid injection head 5 coincide and are all perpendicular to the bottom wall 27. An angle H exists between the centerline of the positioning post 38 and the centerline of the acid injection head 5. The acid injection head 5 can be pushed by the injection head 4 by H degrees or 2H degrees. When pushed by 2H degrees, the opening angle between the seal 17 and the bottom wall 27 is larger, resulting in a larger liquid injection volume.

[0059] The acid injection head 5 consists of a threaded portion 11, a mounting body 45, and a contact body 46 from top to bottom. The threaded portion 11 has a recessed center forming a countersunk hole 47, which mates with the threaded hole 40. A connection port 48 is provided on the threaded portion 11, communicating with the countersunk hole 47. When the threaded portion 11 is installed inside the threaded hole 40, the connection port 48 remains connected to the injection port 41 through the injection channel 42. A through hole 49, communicating with the countersunk hole 47, is formed between the mounting body 45 and the contact body 46. During installation, the acid injection head 5 pushes the telescopic member 29 to extend.

[0060] The mounting body 45 has symmetrically arranged recesses 50, and a second plane 51 is provided in the recesses 50. This allows the acid injection head 5 to be placed in the telescopic member 29 and held in the recesses 50 by a tool, so that the acid injection head 5 can be rotated to mate the threaded part 11 with the threaded hole 40.

[0061] The telescopic component 29 consists of a first connecting portion 52, a first arc-shaped portion 53, a second arc-shaped portion 54, a second connecting portion 55, a telescopic cylinder 56, a third arc-shaped portion 57, and a cylindrical portion 58. An installation chamber 59 is formed in the middle of the telescopic cylinder 56, and an opening / closing area 60 is formed between the first arc-shaped portion 53 and the second arc-shaped portion 54. As the acid injection head 5 pushes, the telescopic component 29 causes the first arc-shaped portion 53, the second arc-shaped portion 54, and the second connecting portion 55 to deflect.

[0062] The telescopic cylinder 56 has multiple pleats (not shown in the figure). When the acid injection head 5 is installed in the mounting chamber 59, the acid injection head 5 pushes the telescopic cylinder 56 to straighten the pleats. The pleats can generate elasticity to maintain tight contact with the acid injection head 5. The telescopic cylinder 56 has an annular protrusion 61 inside, and the lower end of the mounting body 45 has an annular recess 62 that mates with the annular protrusion 61.

[0063] The cylindrical part 58 has a hollowed-out middle section forming a deformation chamber 63. The lower end of the cylindrical part 58 is provided with an opening 64. The contact body 46 is disposed inside the cylindrical part 58. The lower end of the contact body 46 is provided with an arc part 14. The arc part 14 opens the opening 64 and makes the cylindrical part 58 wrap around the arc part 14.

[0064] The first conveyor belt 6 moves the battery 3, causing the seal 17 to open and close with the bottom wall 27, thus injecting acid. Conversely, the first conveyor belt 6 moves the battery 3 in the opposite direction, causing the elastic element 39 to push the seal 17 and bottom wall 27 to close, thus stopping the acid injection.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
