Description

Technical Field

[0001] This utility model relates to the field of battery processing, and in particular to a battery electrolyte injection system. Background Technology

[0002] With the rapid growth of the electric vehicle and portable electronic device markets, the demand for high-performance batteries is increasing. To meet these demands, battery manufacturers are constantly striving to improve battery energy density. Along with the higher requirements for battery energy density, the amount of electrolyte that needs to be injected into the battery during processing is also increasing. However, the internal space of a battery is inherently limited, leading to longer electrolyte injection time and a longer post-injection settling time, significantly impacting battery production efficiency. Simultaneously, the number of related components involved in the battery injection process also increases, such as the need for electrolyte cups, electrolyte cup disassembly and assembly components, and electrolyte cup cleaning components. Therefore, the manufacturing and operating costs of battery processing equipment are high, and it is also detrimental to cost control during equipment modification and replacement.

[0003] Existing technologies include methods that use ultrasonic devices to vibrate the battery during electrolyte injection, thereby accelerating the transmission and wetting speed of the electrolyte inside the battery and thus improving battery production efficiency. However, the vibrations generated by ultrasound can be transmitted to the inside of the battery and affect its internal structure, such as causing active materials to fall off, which leads to a decrease in battery performance and a reduction in yield. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a battery electrolyte injection system, including a battery electrolyte injection settling unit, which comprises:

[0005] Battery electrolyte filling assembly, including:

[0006] A battery electrolyte filling mechanism is used to fill the battery with electrolyte from the top.

[0007] An electromagnetic vibration mechanism, located at the bottom of the battery, includes:

[0008] Battery support plate, used to support the battery;

[0009] An electromagnetic vibrator is installed below the battery support plate. The vibration of the electromagnetic vibrator is transmitted to the battery through the battery support plate, causing the battery to vibrate in the vertical direction.

[0010] A vibration damper is installed below the battery support plate and spaced apart from the electromagnetic vibrator. It includes a flexible part that contacts the battery support plate and is used to buffer the vibration of the battery support plate acting on the electromagnetic vibrator.

[0011] A battery settling assembly is located downstream of the battery filling assembly and receives batteries from the battery filling assembly. It is used to settling the batteries after they have been filled with electrolyte.

[0012] By adopting the above technical solution, the transport of electrolyte within the battery can be accelerated, allowing the electrolyte to fully fill the gaps inside the battery. This enables the electrolyte to be absorbed by the internal electrodes more efficiently, while also ensuring the integrity of the battery's internal structure and preventing damage to the battery's interior. Furthermore, the electromagnetic vibrator is also protected, maintaining normal operation and eliminating the need for frequent replacement and maintenance.

[0013] Optionally, the battery liquid injection system is provided with multiple battery liquid injection and settling units in sequence from upstream to downstream.

The stationary station has multiple rows of battery shelves in a vertical direction. The inbound lifting assembly lifts or lowers the battery to place it on one of the battery shelves, and the outbound lifting assembly removes the battery from the battery shelf and lowers or lifts the battery.

[0018] Optionally, the station includes: an upper bell cover; a lower bell cover; and an upper bell cover lifting mechanism for raising and lowering the upper bell cover in the vertical direction to separate and engage the upper bell cover and the lower bell cover. When the upper bell cover and the lower bell cover are engaged, the battery rack is surrounded by the upper bell cover and the lower bell cover.

[0019] Optionally, the settling station further includes: a lower bell jar rotation sealing mechanism; a bell jar pipe extending into the interior of the upper bell jar and the lower bell jar, including an air inlet valve and an air outlet valve; after the upper bell jar and the lower bell jar are engaged, the lower bell jar rotation sealing mechanism causes the lower bell jar to rotate toward the upper bell jar and tighten, and the bell jar pipe inflates the interior or exhausts the interior.

[0020] Optionally, the battery electrolyte injection mechanism includes a pump-liquid distributor, multiple electrolyte cups, and multiple injection needles connected in sequence. The pump-liquid distributor includes an injection pump and an electrolyte diversion pipe connected in sequence. The electrolyte enters the multiple electrolyte cups through the electrolyte diversion pipe.

Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0037] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0039] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0041] like Figure 1 As shown, this utility model discloses a battery electrolyte filling system 01, including a battery electrolyte filling and settling unit 1. The battery electrolyte filling and settling unit 1 includes a battery electrolyte filling assembly 10 and a battery settling assembly 20. The battery settling assembly 20 is located downstream of the battery electrolyte filling assembly 10 and receives batteries 0 from the battery electrolyte filling assembly 10. The batteries 0 are conveyed in the system according to the system's battery processing sequence, with later processes located downstream of earlier processes. The conveying direction of the batteries 0 in the system is, for example... Figure 1As shown in direction A, that is, along the transport direction of battery 0 in system 01, the battery electrolyte filling assembly 10 and the battery settling assembly 20 are arranged sequentially. After the battery 0 is filled with electrolyte in the battery electrolyte filling assembly 10, it is transferred to the battery settling assembly 20 for settling so that the electrolyte can be fully impregnated.

[0042] Furthermore, combined Figure 1 and Figure 2 The battery fluid injection assembly 10 includes a battery fluid injection mechanism 11 and an electromagnetic vibration mechanism 12. The battery fluid injection mechanism 11 injects fluid into the battery 0 from the top. The electromagnetic vibration mechanism 12 is located at the bottom of the battery 0 and includes a battery support plate 123 for supporting the battery, an electromagnetic vibrator 121 mounted below the battery support plate 123, and a vibration buffer, with the vibration buffer spaced apart from the electromagnetic vibrator 121. The electromagnetic vibrator 121 transmits vibration from the bottom of the battery 0 to the battery 0, specifically through the battery support plate 123, causing the battery 0 to vibrate vertically. The vibration buffer includes a flexible portion that contacts the battery support plate 123, which buffers the vibration of the battery support plate 123 acting on the electromagnetic vibrator 121. The flexible portion may be, for example, the silicone material portion at the top of the vibration buffer.

[0043] In other words, while the battery filling mechanism 11 is filling the battery 0 with electrolyte, the electromagnetic vibrator 121 transmits vibration from the bottom of the battery 0, causing the battery 0 to vibrate vertically. The mechanical vibration generated by the electromagnetic vibrator 121 is transmitted to the battery, ensuring that the electrolyte fully fills the internal gaps and improves the utilization rate of the battery's internal space. Furthermore, unlike ultrasonic vibration, the mechanical vibration of electromagnetic vibration is not transmitted to the battery's interior, maintaining the integrity of the battery's internal structure, especially the active materials. The active materials will not detach due to vibration, ensuring battery performance. In addition, after the battery support plate 123 is vibrated by the electromagnetic vibrator 121, it will also relatively react mechanically to the electromagnetic vibrator 121 in the direction towards the electromagnetic vibrator 121. At this time, the flexible part of the vibration damper can buffer the reaction vibration received by the electromagnetic vibrator 121, preventing the electromagnetic vibrator 121 from being damaged. Furthermore, the vertical vibration of the battery, coordinated with the electrolyte injection direction and the force of gravity acting on the electrolyte, facilitates faster and more even distribution of the electrolyte within the battery, allowing for quicker electrolyte wetting. Simultaneously, the accelerated wetting speed eliminates or reduces the need for components such as the electrolyte cup, electrolyte cup assembly / disassembly components, and electrolyte cup cleaning components, lowering production, maintenance, and cleaning costs, and also reducing the equipment's size for easier manufacturing.

[0044] In a specific embodiment of this utility model, the battery liquid injection system is provided with multiple battery liquid injection and settling units sequentially from upstream to downstream. The battery liquid injection system also includes a battery transport assembly extending between the upstream and downstream sides, which sequentially transports the batteries through the multiple battery liquid injection and settling units. Specifically, as shown... Figure 3 As shown, along the direction from upstream to downstream (e.g.) Figure 3 In direction A), the battery electrolyte filling system 01 is sequentially provided with multiple battery electrolyte filling and settling units, namely battery electrolyte filling and settling unit 1 and battery electrolyte filling and settling unit 1'. Each battery electrolyte filling and settling unit includes a battery electrolyte filling component and a battery settling component. Specifically, battery electrolyte filling and settling unit 1 includes a battery electrolyte filling component 10 and a battery settling component 20, and battery electrolyte filling and settling unit 1' includes a battery electrolyte filling component 10' and a battery settling component 20'. Under the transmission of the battery transport component, the battery 0 can sequentially pass through battery electrolyte filling component 10, battery settling component 20, battery electrolyte filling component 10', and battery settling component 20', that is, the battery can be filled and settling twice. Specifically, the original one-time electrolyte filling is divided into two processes. The amount of electrolyte injected each time can be determined according to the electrolyte volume of different batteries and the internal space of the battery. For example, the first injection is 60%-70% of the total electrolyte volume, and the second injection is 40%-30% of the total electrolyte volume. After each injection, the battery is settling. By injecting electrolyte in small, multiple stages, the injection time can be shortened. The small amount of electrolyte transported within the battery will not cause blockages, thus shortening the settling time and ensuring faster absorption by the electrodes. This frees up more space inside the battery for more efficient electrolyte entry during subsequent injections. The two battery injection assemblies can be further equipped with multiple battery settling assemblies, or additional battery settling units can be added to the battery injection system 01, for example, three, four, or even more. Furthermore, each battery injection assembly is equipped with an electromagnetic vibration mechanism. The combination of multiple injections and electromagnetic vibration allows for more efficient electrolyte transport within the battery, further improving production efficiency. Traditional battery injection equipment requires vacuuming, maintaining, and breaking the vacuum in the battery to allow for rapid electrolyte infiltration and to quickly make room for the next electrolyte injection. However, based on the combination of multiple injections and electromagnetic vibration, these vacuuming, maintaining, and breaking steps can be eliminated, further reducing costs. Furthermore, multiple battery electrolyte filling and settling units can simultaneously fill and settling multiple battery groups, resulting in higher efficiency.

[0045] In one specific embodiment of this utility model, the battery delivery assembly can transport batteries back and forth between the battery injection assembly and the battery settling assembly in a battery injection and settling unit. Batteries can undergo multiple injections and settling processes within the same battery injection and settling unit. Therefore, only one or fewer battery injection and settling units need to be set up, reducing equipment costs. When multiple battery injection and settling units are provided, multiple sets of batteries can also simultaneously undergo multiple injections and settling processes within a single battery injection and settling unit.

[0046] In a specific embodiment of this utility model, such as Figure 2 As shown, the electromagnetic vibration mechanism 12 includes a battery support plate 123 and an electromagnetic vibrator mounting plate 124. The battery support plate 123 supports the battery 0 so that the battery injection mechanism 11 can inject electrolyte into the battery 0. The electromagnetic vibrator mounting plate 124 is located below the battery support plate 123 and is vertically spaced from the battery support plate 123. The electromagnetic vibrator 121 is installed between the battery support plate 123 and the electromagnetic vibrator mounting plate 124, that is, the electromagnetic vibrator 121 is installed in the gap between the battery support plate 123 and the electromagnetic vibrator mounting plate 124. The electromagnetic vibrator 121 is in contact with both the battery support plate 123 and the electromagnetic vibrator mounting plate 124, and the vibration of the electromagnetic vibrator 121 is transmitted to the battery 0 through the battery support plate 123. At this time, the battery support plate 123 serves as the vibration transmission medium between the electromagnetic vibrator 121 and the battery 0. The battery support plate 123 and the electromagnetic vibrator mounting plate 124 ensure that the battery 0 and the electromagnetic vibrator 121 are stably positioned in the battery electrolyte injection stationary unit 1, guaranteeing production stability even during vibration. Specifically, one end of the electromagnetic vibrator 121 is mounted on the electromagnetic vibrator mounting plate 124, and the other end is mounted on the battery support plate 123.

[0047] In a specific embodiment of this utility model, such as Figure 2As shown, the vibration damper is a buffer support 122, which is installed between the electromagnetic vibrator mounting plate 124 and the battery support plate 123. Specifically, the buffer support 122 includes a support base 1221 and a flexible support 1222. The support base 1221 is installed on the electromagnetic vibrator mounting plate 124, and the flexible support 1222 is installed on the support base 1221. The flexible support 1222 is in contact with the battery support plate 123 but is not fixedly connected. The flexible support 1222 can buffer some of the downward mechanical energy during battery vibration, protecting the electromagnetic vibrator 121 and preventing it from being crushed. More specifically, the flexible support 1222 is a cylindrical rubber pad. In one specific embodiment of this utility model, electromagnetic vibrators 121 and buffer supports 122 are alternately arranged between electromagnetic vibrator mounting plate 124 and battery support plate 123. There are n columns and m rows of electromagnetic vibrators 121 between the electromagnetic vibrator mounting plate 124 and battery support plate 123, and n-1 columns and m rows of buffer supports 122 between the electromagnetic vibrator mounting plate 124 and battery support plate 123, where m and n are positive integers greater than or equal to 1. For example, there are 4 columns and 4 rows of electromagnetic vibrators 121 and 3 columns and 4 rows of buffer supports 122 between the electromagnetic vibrator mounting plate 124 and battery support plate 123, all arranged in an array, and one buffer support 122 is installed between every two electromagnetic vibrators 121. The electromagnetic vibrator mounting plate 124 and the battery support plate 123 can provide comprehensive support and cushioning, especially when the batteries are arranged in multiple columns and rows and are injected with liquid at the same time, such as 12*4 batteries being injected with liquid at the same time. The buffer support column 122 and the electromagnetic vibrator 121, which are distributed in multiple columns and rows and are alternately distributed, can effectively act on each battery.

[0048] In a specific embodiment of this utility model, such as Figure 4 As shown, the battery stationary assembly 20 includes components extending from upstream to downstream (along...). Figure 4 The battery placement assembly 20 (shown in direction A) consists of an inbound lifting component 21, a stationing station 22, and an outbound lifting component 23 arranged sequentially. The stationing station 22 has multiple rows of battery racks 221 arranged vertically. The inbound lifting component 21 raises or lowers the battery 0 to place it on a row of battery racks 221. The outbound lifting component 23 unloads the battery 0 from the battery racks 221 and lowers or raises it. In other words, when a battery 0 is transferred to the battery stationing assembly 20, it does not directly enter the stationing station 22. Instead, it is first received by the inbound lifting component 21 at the same height. Since the inbound lifting component 21 can move up and down, it can place the battery 0 on any row of battery racks 221 in the stationing station 22 that has not yet been filled with batteries. The battery 0 then rests in the stationing station 22. After resting, it is unloaded by the outbound lifting component 23 and raised or lowered to the height of the transmission device, which then continues the transmission. This allows for the simultaneous resting of a large number of batteries, further improving production efficiency.

[0049] In a specific embodiment of this utility model, reference continues... Figure 4 The battery storage station 22 includes an upper bell cover 222, a lower bell cover 223, and an upper bell cover lifting mechanism 224. The upper bell cover lifting mechanism 224 is used to raise and lower the upper bell cover 222 vertically to separate and engage the upper bell cover 222 and the lower bell cover 223. When the upper bell cover 222 and the lower bell cover 223 are engaged, the battery shelf 221 is surrounded by the upper bell cover 222 and the lower bell cover 223. Through the upper bell cover lifting mechanism 224, the upper bell cover 222 and the lower bell cover 223 can work closely together to form a space for battery storage.

[0050] In a specific embodiment of this utility model, reference continues... Figure 4 Furthermore, the settling station 22 also includes a lower bell-shaped rotating sealing mechanism 225 and a bell-shaped pipe 226. The bell-shaped pipe 226 extends into the interior of the upper bell-shaped housing 222 and the lower bell-shaped housing 223, and includes an inlet valve 2261 and an exhaust valve 2262. After the upper bell-shaped housing 222 and the lower bell-shaped housing 223 are engaged, the lower bell-shaped rotating sealing mechanism 225 rotates the lower bell-shaped housing 223 toward the upper bell-shaped housing 222 and tightens it. The bell-shaped pipe 226 inflates or vents air from the interior formed by the upper bell-shaped housing 222 and the lower bell-shaped housing 223, allowing the battery to circulate under high pressure, high pressure, and normal pressure conditions, thus ensuring more thorough electrolyte wetting. Specifically, when the battery rack 221 is full, the upper bell-shaped lifting mechanism 224 starts operating, causing the upper bell-shaped housing 222 to descend and combine with the lower bell-shaped housing 223, and the lower bell-shaped rotating sealing mechanism 225 seals both. Subsequently, the inlet valve 2261 of the bell jar pipe 226 opens, allowing nitrogen and other gases to be introduced into the interior, thus beginning the process of pressurizing the interior. When the pressure reaches a certain value, the inlet valve 2261 closes, and the pressure is maintained. After the pressure maintenance time is over, the exhaust valve 2262 opens, allowing exhaust gas to escape from the interior. When the internal pressure returns to normal, one high-pressure cycle is complete. The settling time, high-pressure maintenance time, and number of cycles can be adjusted according to the actual production settling effect.

[0051] Through the coordination and cooperation of the various parts of the battery settling assembly 20, the battery after liquid injection can undergo a settling process efficiently and fully.

[0052] In a specific embodiment of this utility model, such as Figure 2As shown, the battery electrolyte injection mechanism 11 includes a pump-liquid distributor 111, multiple electrolyte cups 112, and multiple injection needles 113 connected in sequence. The pump-liquid distributor 111 includes an injection pump 1111 and an electrolyte distribution pipe 1112 connected in series. The electrolyte enters the multiple electrolyte cups 112 through the electrolyte distribution pipe 1112. When all the electrolyte has entered the electrolyte cups 112, the electromagnetic vibration mechanism 12 causes the battery 0 to vibrate, and the electrolyte enters the battery 0 from the electrolyte cups 112 through the injection needles 113. Specifically, the pump-liquid distributor 111 also includes an injection pump inlet pipe 1113 and an injection pump outlet pipe 1114. The electrolyte enters the injection pump 1111 from the inlet and then flows into the electrolyte distribution pipe 1112 from the injection pump outlet pipe 1114. Each pipe of the electrolyte distribution pipe 1112 is also equipped with a distribution pipe valve 1115.

[0053] In a specific embodiment of this utility model, such as Figure 2 As shown, the battery electrolyte filling assembly 10 also includes a battery sealing detection mechanism 13. The battery sealing detection mechanism 13 includes a vacuum pipe 131, a vacuum valve 132, and a vacuum pressure gauge 133. When the vacuum valve 132 is open, the vacuum pipe 131 evacuates the battery 0, and the vacuum pressure gauge 133 displays the internal pressure value of the battery 0. When the internal vacuum of the battery 0 reaches a certain value, the vacuum valve 132 closes, the battery 0 begins to maintain a vacuum, and the change in pressure value of the vacuum pressure gauge 133 is recorded. A small change indicates that the battery sealing is calibrated, and the battery will proceed to the next step of electrolyte filling; otherwise, the battery will be marked and will not proceed to the next step of electrolyte filling. The electrolyte injection needle 113 includes a main pipe 1131 and a Y-shaped branch pipe 1132. One branch pipe 1132a of the Y-shaped branch pipe is connected to the vacuum pipe 131, and the other branch pipe 1132b of the Y-shaped branch pipe is connected to the electrolyte cup 112. The battery sealing test mechanism 13 can test the seal between the battery filling port and the outlet nozzle of the injection needle 113, and can also evacuate the battery 0 to allow the battery 0 to absorb the electrolyte in the electrolyte cup 112 more quickly. Furthermore, the battery sealing test mechanism 13 also includes a receiving box 134 to buffer residual electrolyte extracted from the battery. Even further, the vacuum pipeline 131 includes a vacuum main pipe 1311 and a vacuum main pipe branch pipe 1312, with the vacuum main pipe branch pipe 1312 connected to a branch pipe 1132a of the Y-shaped branch pipe. Specifically, the electrolyte cup 112 is mounted on the electrolyte cup mounting base 1121, and the electrolyte cup 112 and the injection needle 113 are connected via an electrolyte cup outlet pipe 1122, which is equipped with an electrolyte injection valve 1123. More specifically, the electrolyte cup outlet pipe 1122 is connected to another branch pipe 1132b of the Y-shaped branch pipe.

[0054] In a specific embodiment of this utility model, such as Figure 5 As shown, and in combination Figure 1 and Figure 3 The battery liquid injection system 01 also includes a battery delivery assembly 30, which is located below the battery liquid injection assembly 10. Its extension length between upstream and downstream sections is longer than that of the battery liquid injection assembly 10. This assembly can deliver batteries between the battery liquid injection mechanism 11 and the electromagnetic vibration mechanism 12 for vibration-type liquid injection, and can also deliver the injected batteries to the station-entry lifting assembly 21. When the system has multiple battery liquid injection stationary units, multiple battery delivery assemblies can also be correspondingly provided, for example... Figure 5 From upstream to downstream (along) Figure 5 In the direction A shown, battery transport components 30, 30', and 30'' are sequentially arranged. Specifically, battery transport component 30 includes battery tray 31, which loads and positions the battery to ensure its stability and safety during liquid injection, settling, and transfer. Battery transport component 30 also includes battery tray roller line 32. The main function of battery tray roller line 32 in this system is to provide power, support, and guidance for the forward movement of battery tray 31. Battery tray roller line 32 includes side support plates 321 on both sides of the tray, rollers 322 on both sides of the tray, and roller line support columns 323. The power of battery tray roller line 32 is provided by an external motor and transmission components. Its length adopts a segmented design, for example, designed as three segments. Battery transport component 30' can also have only battery tray 31' and battery tray roller line 32', that is, the battery is removed from the line after two liquid injections.

[0055] In a specific embodiment of this utility model, combined with Figure 1 and Figure 3 , Figure 4 , Figure 5 Furthermore, the inbound lifting assembly 21 includes a battery tray inbound station trolley 211, and the outbound lifting assembly 23 includes a battery tray outbound station trolley 231. The battery tray inbound station trolley 211 can remove the battery tray 31 from the battery tray roller conveyor 32 and transport it into the bell-shaped enclosure of the station 22. The battery tray outbound station trolley 231 can remove the battery tray 31 from inside the bell-shaped enclosure of the station 22 and place it onto the battery tray roller conveyor 32. The battery tray inbound station trolley 211 and the battery tray outbound station trolley 231 can pick up and place the battery tray 31 from both sides, and their height for picking up and placing the battery tray 31 can be freely controlled, allowing for multi-layer storage of batteries within the station 22. Furthermore, as... Figure 2As shown, the battery conveying assembly 30 includes a battery pallet positioning lifter 33, which is located upstream of the inbound lifting assembly 21. When the battery pallet 31 flows to the top of the battery pallet positioning lifter 33, the battery pallet positioning lifter 33 will lift the battery pallet 31 again to detach it from the battery pallet roller line 32. When the battery pallet 31 is lifted, the battery pallet entering the station trolley 211 begins to remove the battery pallet 31 and sends it onto the battery shelf 221 through transfer and lifting. Correspondingly, the battery conveying assembly 30 includes a battery pallet positioning lifter 34, which is located downstream of the outbound lifting assembly 23. After the stationing is completed, the lower bell-shaped rotating sealing mechanism 225 begins to unlock, and the upper bell-shaped cover 222 rises. At this time, the battery pallet exiting the station trolley 231 will remove the battery pallet 31 from the battery shelf 221 and send the battery pallet 31 onto the battery pallet positioning lifter 34 through transfer and lifting. After the battery tray positioning and lifting device 34 catches the battery tray 31, it will place the battery tray 31 back onto the battery tray roller line 32, where the battery tray 31 continues to flow forward. If there are multiple battery liquid injection and settling units in the system, a new round of electromagnetic vibration liquid injection and settling will continue, repeating the above process.

[0056] In a specific embodiment of this utility model, reference continues... Figure 1-Figure 2 and combined Figure 5 The battery filling assembly 10 includes a tray blocking mechanism 14, and the electromagnetic vibration mechanism 12 includes a vibration mechanism lifting cylinder 125. The vibration mechanism lifting cylinder 125 is connected to the electromagnetic vibrator mounting plate 124 and can drive the electromagnetic vibrator mounting plate 124 and the battery support plate 123 to rise and fall together. When the battery tray 31 flows forward on the battery tray roller line 32 and reaches the battery support plate 123, the tray blocking mechanism 14 rises to stop the battery tray 31 from continuing to move forward, and the vibration mechanism lifting cylinder 125 lifts upward, causing the battery support plate 123 and the battery tray 31 on it to rise together. Specifically, the battery support plate 123 is provided with a positioning pin, which can accurately ensure the positioning accuracy of the battery tray 31 during the lifting process. When the battery support plate 123 is lifted into place, the battery tray 31 will detach from the battery tray roller line 32. The battery liquid injection mechanism 11 includes a liquid injection mechanism lifting cylinder 114. At this time, the liquid injection mechanism lifting cylinder 114 will press down, and the battery liquid injection mechanism 11 will seal the battery 0 in the battery tray 31. The battery liquid injection assembly 10 will detect, inject liquid, and vibrate the battery.

[0057] In a specific embodiment of this utility model, the battery tray 31 holds 12*4 batteries, and the battery injection mechanism 11 can inject electrolyte into 12*4 batteries at a time. The battery injection mechanism 11 has 8 sets of pump-liquid distributors 111, electrolyte cups 112, and injection needles 113. Each set of pump-liquid distributors 111 has an electrolyte diversion pipe 1112 that can divide the electrolyte into 6 paths. The 8 sets can sequentially complete the injection of electrolyte into 8*6 batteries. Further, there are 12*4 electrolyte cups. Even further, there are 12*4 injection needles. At the same time, there are 8 sets of battery sealing detection mechanisms 13. Each set divides one vacuum into 6 paths through a vacuum main pipe diversion manifold 1312. The 8 sets of vacuum main pipes 1311 are connected to 48 vacuum diversion branch pipes 1312.
