Description

Technical Field

[0001] This utility model relates to the field of battery liquid filling and settling tank technology, specifically a lifting mechanism for a battery liquid filling and settling tank. Background Technology

[0002] In the production process of secondary batteries such as lithium-ion batteries, the battery electrolyte injection settling tank is a key piece of equipment for achieving precise electrolyte injection and ensuring the stability of the battery's chemical reaction. The opening and closing accuracy and locking stability of its tank lid directly affect the electrolyte injection sealing performance, electrolyte utilization rate, and the quality of the finished battery. Currently, there are two main problems with the lifting mechanism of the tank lid in the industry: Firstly, the precision and controllability of the can lid lifting mechanism are insufficient. Existing lifting mechanisms mostly adopt manual crank-driven or simple cylinder-driven modes: manual crank lifting requires repeated manual adjustment, which is not only labor-intensive and inefficient, but also makes it difficult to accurately control the alignment height between the can lid and the can body, and can lid deviation is easily caused by human operation errors; although cylinder drive can improve efficiency, it lacks an effective guiding and restraining structure. During the lifting process, the can lid is easily affected by airflow fluctuations or mechanism gaps, resulting in horizontal deviation. This causes the can lid and the can body sealing surface to not be completely sealed, which in turn leads to electrolyte leakage or external air seepage into the can body. This not only wastes raw materials, but may also damage the inert environment inside the battery and affect the battery's electrochemical performance. Secondly, the convenience and stability of the tank lid locking structure are lacking. To prevent the tank lid from shifting due to vibration or pressure changes during the filling process, existing locking methods mostly use single-sided bolt tightening or snap-on locking: single-sided bolt locking requires manual tightening of each bolt, which is time-consuming and labor-intensive; snap-on locking is simple to operate, but the locking strength is low, and the snaps are easy to loosen when the internal pressure of the tank fluctuates or the equipment vibrates during operation, which cannot form a continuous and stable locking effect; some double-sided locking structures require independent operation on both sides of the tank lid, which is cumbersome, and the locking progress on both sides is difficult to synchronize, which can easily cause the tank lid to tilt, further aggravating the sealing risks, and failing to meet the needs of efficient and stable large-scale production. Therefore, there is an urgent need for an improved lifting mechanism that can achieve precise lifting and lowering of the can lid, as well as convenient and stable locking. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a lifting mechanism for a battery liquid filling and settling tank, which has the advantages of being easy to use and having precise positioning.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lifting mechanism for a battery electrolyte filling and settling tank, comprising a support base, a battery electrolyte filling and settling tank body fixedly connected to the top of the support base, guide rods fixedly connected to all four sides of the top of the support base, a top frame fixedly connected to the top of the guide rods, a movable plate slidably connected to the surface of the guide rods, an electric telescopic rod fixedly connected to the top of the top frame via a bracket, an opening provided at the top of the movable plate, a battery electrolyte filling and settling tank cover fixedly connected inside the opening, the bottom of the battery electrolyte filling and settling tank cover extending below the movable plate, and the top of the battery electrolyte filling and settling tank cover extending above the movable plate. The output end of the electric telescopic rod is fixedly connected to the top of the battery liquid filling tank cover. Support frames are fixedly connected to both sides of the top of the support base. The support frames are fixedly connected to the top frame, and locking teeth are fixedly connected to the adjacent side of the two support frames. There are several locking teeth, which are evenly distributed on the side of the support frame near the battery liquid filling tank cover. Locking frames are provided on both sides of the top of the movable plate. Limiting teeth are provided on the surface of the locking frames. The limiting teeth cooperate with the locking teeth. Sliding grooves are provided on the front and rear sides of both sides of the top of the movable plate, and the sliding grooves are slidably connected with the locking frames. The battery liquid filling tank cover is used in conjunction with the battery liquid filling tank body.

[0005] As a preferred embodiment of the present invention, the top of the movable plate is provided with an annular groove, and a rotating ring is rotatably connected inside the annular groove. Both sides of the top of the rotating ring are rotatably connected with connecting rods, and the end of the connecting rod away from the rotating ring is hinged to the locking frame.

[0006] As a preferred embodiment of this utility model, the surface of the rotating ring is fixedly connected with teeth, and the number of teeth is several. The top of the movable plate is provided with a groove, and a servo motor is fixedly connected inside the groove. The output end of the servo motor is fixedly connected with a gear, and the gear meshes with the teeth.

[0007] As a preferred embodiment of this invention, a protective cover is fixedly connected to the top of the movable plate, and the gears and teeth are located inside the protective cover.

[0008] As a preferred embodiment of this utility model, the movable plate is internally fixedly connected to a bearing, with the outer ring of the bearing fixedly connected to the movable plate and the inner ring of the bearing fixedly connected to the rotating ring.

[0009] As a preferred embodiment of this invention, a reinforcing frame is fixedly connected to the surface of the support frame, and the reinforcing frame is fixedly connected to the support base.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a support base to provide stable support for the overall structure, ensuring that the battery electrolyte filling tank is firmly installed and preventing shaking during equipment operation. The guide rod can accurately guide the up and down sliding of the movable plate, preventing the movable plate from deviating during the lifting and lowering process. This ensures accurate alignment between the battery electrolyte filling tank cover and the tank body, avoiding problems such as sealing failure, electrolyte leakage, or air infiltration caused by misalignment. The electric telescopic rod provides stable power for the lifting and lowering of the tank cover and can accurately control the lifting and lowering range of the tank cover. The locking teeth on the support frame cooperate with the limiting teeth of the locking frame to achieve a stable lock after the tank cover is lifted and lowered to the target height, preventing the tank cover from being displaced by external forces during the filling process. The sliding groove provides a stable path for the sliding of the locking frame, ensuring smooth locking operation. This device has the advantages of being easy to use and having accurate positioning.

[0011] 2. This utility model provides a linkage drive structure for the sliding of the locking frame by cooperating with the rotating ring and connecting rod in the annular groove at the top of the movable plate. When the rotating ring rotates in the annular groove, it can synchronously drive the connecting rods on both sides to move, thereby driving the two locking frames to slide along the slide groove. The two locking frames move in opposite directions. This linkage structure eliminates the need to operate the two locking frames separately, simplifies the locking operation process, reduces manual intervention steps, and improves operation efficiency.

An electric telescopic rod 7 is fixedly connected to the top of the top frame 3 via a bracket. An opening is provided at the top of the movable plate 5, and a battery electrolyte filling and settling tank cover 6 is fixedly connected inside the opening. The bottom of the battery electrolyte filling and settling tank cover 6 extends below the movable plate 5, and the top of the battery electrolyte filling and settling tank cover 6 extends above the movable plate 5. The output end of the electric telescopic rod 7 is fixedly connected to the top of the battery electrolyte filling and settling tank cover 6. Support frames 8 are fixedly connected to both sides of the top of the support base 1. The support frames 8 are fixedly connected to the top frame 3, and locking teeth 9 are fixedly connected to adjacent sides of the two support frames 8. The number of locking teeth 9 is several, and the locking teeth 9 are evenly distributed on the side of the support frame 8 near the battery electrolyte filling and settling tank cover 6. Locking frames 10 are provided on both sides of the top of the movable plate 5. The surface of the locking frame 10 is provided with limiting teeth 11, which cooperate with locking teeth 9. The front and rear sides of the top of the movable plate 5 are provided with sliding grooves, which are slidably connected with the locking frames 10.

These will not be described in detail here. The contents not described in detail in this specification are existing technologies known to those skilled in the art. This application will not describe them in detail.

[0016] refer to Figure 2 The top of the movable plate 5 is provided with an annular groove, and a rotating ring 12 is rotatably connected inside the annular groove. Both sides of the top of the rotating ring 12 are rotatably connected with connecting rods 13, and the end of the connecting rod 13 away from the rotating ring 12 is hinged to the locking frame 10.

[0017] As a technical optimization of this utility model, the rotating ring 12 in the annular groove at the top of the movable plate 5 cooperates with the connecting rod 13 to provide a linkage drive structure for the sliding of the locking frame 10. When the rotating ring 12 rotates in the annular groove, it can synchronously drive the connecting rods 13 on both sides to move, thereby driving the two locking frames 10 to slide along the slide groove. The two locking frames 10 move in opposite directions. This linkage structure eliminates the need to operate the two locking frames 10 separately, simplifies the locking operation process, reduces manual intervention steps, and improves operation efficiency.

[0018] refer to Figure 3 The rotating ring 12 has teeth 16 fixedly connected to its surface. The number of teeth 16 is several. The top of the movable plate 5 is provided with a groove, and a servo motor 14 is fixedly connected inside the groove. The output end of the servo motor 14 is fixedly connected to a gear 15, which meshes with the teeth 16.

[0019] As a technical optimization of this utility model, the teeth 16 on the surface of the rotating ring 12 mesh with the gear 15 at the output end of the servo motor 14 to form a precise transmission structure. The servo motor 14 can provide precise and controllable power for the rotation of the rotating ring 12. Through the stable meshing of the gear 15 and the teeth 16, the rotation angle of the rotating ring 12 can be precisely adjusted, thereby precisely controlling the sliding distance of the connecting rod 13 pushing the locking frame 10, ensuring that the meshing depth of the limiting tooth 11 and the locking tooth 9 is appropriate, so that the locking is not unstable due to shallow meshing, nor is the teeth 16 worn due to deep meshing.

[0020] refer to Figure 1 A protective cover 17 is fixedly connected to the top of the movable plate 5, and the gear 15 and teeth 16 are located inside the protective cover 17.

[0021] As a technical optimization of this utility model, the gear 15 and teeth 16 are protected by the protective cover 17 on the top of the movable plate 5. The protective cover 17 can prevent the operator from accidentally coming into contact with the moving gear 15 and teeth 16 during the operation of the equipment, reduce safety hazards and improve the safety of equipment use.

[0022] refer to Figure 2 The movable plate 5 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the movable plate 5, while the inner ring of the bearing is fixedly connected to the rotating ring 12.

[0023] As a technical optimization of this utility model, the bearing inside the movable plate 5 can effectively reduce the frictional resistance between the rotating ring 12 and the movable plate 5, making the rotation process of the rotating ring 12 in the annular groove smoother, reducing the mechanical wear between the rotating ring 12 and the movable plate 5, extending the service life of the rotating ring 12 and the movable plate 5, avoiding the rotating ring 12 from jamming or getting stuck due to excessive friction, and ensuring that the rotating ring 12 can continuously and stably provide power to the connecting rod 13.

[0024] refer to Figure 1 A reinforcing frame 18 is fixedly connected to the surface of the support frame 8, and the reinforcing frame 18 is fixedly connected to the support base 1.

[0025] As a technical optimization of this utility model, the reinforcing frame 18 on the surface of the support frame 8 effectively enhances the connection strength between the support frame 8 and the support base 1. This prevents the support frame 8 from deforming or shifting when subjected to the impact forces of the movable plate 5, the battery electrolyte filling tank cover 6, and during lifting and lowering, ensuring that the support frame 8 always maintains a stable installation position. This, in turn, ensures the fixed position of the locking teeth 9 on the support frame 8, preventing the locking teeth 9 from shifting due to deformation of the support frame 8, which would affect the precise engagement of the limiting teeth 11 and the locking teeth 9. The reinforcing frame 18 extends the service life of the support frame 8, preventing damage due to long-term stress and reducing equipment maintenance frequency and costs.

[0026] The working principle and usage process of this utility model are as follows: Before using the lifting mechanism of the battery liquid filling and settling tank, the entire device must be thoroughly inspected. At the same time, the appearance and connection lines of the electric telescopic rod 7 and the servo motor 14 should be checked to ensure that there is no damage or poor contact. The sealing surfaces of the battery liquid filling and settling tank body 4 and the battery liquid filling and settling tank cover 6 should be clean and free of impurities or stains to prevent subsequent sealing failure. The surface of the guide rod 2 should be smooth and free of jamming or obstruction to ensure that the movable plate 5 can slide smoothly.

[0027] After inspection, place the battery-related components to be processed into the battery electrolyte filling tank 4, ensuring accurate placement so as not to affect the closure of the tank lid. Then, activate the electric telescopic rod 7. The output end of the electric telescopic rod 7 moves the battery electrolyte filling tank lid 6 downwards. Since the movable plate 5 is fixedly connected to the battery electrolyte filling tank lid 6 and slidably connected to the guide rod 2, under the guidance of the guide rod 2, the movable plate 5 descends smoothly and synchronously with the tank lid, avoiding any deviation or shaking, until the battery electrolyte filling tank lid 6 is in contact with the top of the battery electrolyte filling tank 4, achieving a sealed state. At this point, close the electric telescopic rod 7 and stop the descent. Next, the servo motor 14 is started. The output end of the servo motor 14 drives the gear 15 to rotate. Since the gear 15 meshes with the teeth 16 on the surface of the rotating ring 12, the rotation of the gear 15 will drive the rotating ring 12 to rotate in the annular groove on the top of the movable plate 5. During the rotation of the rotating ring 12, the connecting rods 13 on both sides of its top move accordingly. The end of the connecting rod 13 away from the rotating ring 12 is hinged to the locking frame 10, which in turn pushes the locking frame 10 to slide along the sliding grooves on both sides of the top of the movable plate 5. The locking frames 10 on both sides move away from each other until the limiting teeth 11 on the surface of the locking frame 10 are fully engaged with the locking teeth 9 on the support frame 8, thereby locking the movable plate 5 and preventing the can cover from shifting due to external force during the liquid filling process, ensuring the stability of the liquid filling process.
