Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a vacuum acid filling device for the trial production of AGM batteries. Background Technology

[0002] During the battery production process, acid needs to be added to each cell of the battery. The acid is injected into the battery casing through an acid injection nozzle, which allows the chemical reaction inside the battery to take place and make it usable. The acid injection device not only improves work efficiency but also improves work safety.

[0003] Currently, the acid filling equipment commonly used in the industry has the following key technical defects. After the traditional gravity-fed AGM battery prototype vacuum acid filling device is completed, when the acid filling gun is separated from the battery, due to the lack of an effective sealing structure, the residual acid in the gun barrel will continue to drip due to gravity during the movement. This not only causes pollution of the working environment, but also leads to inaccurate acid filling amount in the subsequent batteries. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum acid filling device for AGM battery prototyping, which solves the problem that in existing vacuum acid filling devices for AGM battery prototyping, after acid filling is completed and the acid filling gun is separated from the battery, the residual acid in the gun barrel will continue to drip due to gravity during the movement due to the lack of an effective sealing structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a vacuum acid filling device for AGM battery trial production, comprising a frame, an acid filling base, an acid filling gun, and a conveyor belt, and further comprising a vacuum tube and an acid delivery pipe connected to the vacuum tube. The acid delivery pipe is connected to the acid filling gun, and a flow guide joint is provided below the acid filling gun. The flow guide joint has a cavity inside, and the flow guide joint is slidably connected to the acid filling gun. There is an acid outlet at the bottom of the flow guide joint, and a water-blocking ball is provided inside the flow guide joint to block the acid outlet. The water-blocking ball is connected to a lifting device. The acid filling gun is inserted into the flow guide joint and pushes the lifting device to move the water-blocking ball away from the acid outlet.

[0006] Furthermore, the flow guide connector has an acid inlet, the acid filling gun is inserted into the acid inlet, and a buffer device is provided on the outside of the flow guide connector, the buffer device being connected to the acid filling seat.

[0007] Furthermore, the lifting device includes a guide column, a lifting rope, and a drive bar. The guide column extends from the acid outlet into the flow guide connector. A through groove is provided on one side of the guide column. The lifting rope passes through the through groove from inside the guide column and is connected to the water-blocking ball. The drive bar is disposed inside the guide column and slides along the inner wall of the guide column, and is connected to the lifting rope.

[0008] Furthermore, the diameter of the acid injection gun is the same as the inner diameter of the guide column. The acid injection gun is inserted into the guide column to push the drive bar down, and the water-blocking ball is lifted by the lifting rope.

[0009] Furthermore, the buffer device includes side ears symmetrically arranged on the periphery of the flow guide connector, each side ear having an upwardly extending sliding rod, the sliding rod being slidably connected to the acid filling seat, and a limiting block being provided on the sliding rod above the acid filling seat.

[0010] Furthermore, a buffer spring is provided between the side ear and the acid filling seat, and the buffer spring is sleeved on the sliding rod.

[0011] Furthermore, a lifting cylinder is provided above the acid filling seat, and the lifting cylinder is connected to the frame.

[0012] Furthermore, the acid filling gun is equipped with a vacuum pump.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] A negative pressure acid suction system is formed by vacuum tubes and acid delivery tubes to ensure stable and efficient acid delivery. When the acid filling gun is inserted into the guide connector, its cooperation with the guide column pushes the drive bar downward. The lifting rope links the water-blocking ball to rise and open the acid outlet, realizing acid filling into the battery. When the acid filling gun rises, the water-blocking ball automatically resets and seals the acid outlet under the action of gravity, effectively solving the leakage problem of traditional vacuum acid filling devices used in AGM battery trial production. The buffer device set on the outside of the guide connector can absorb the impact force of the acid filling gun, and at the same time can press the battery to ensure that the acid outlet can be accurately connected to the battery's acid storage tank. The guide column through-slot structure and sliding drive bar design, combined with the guide column inner diameter of the same diameter as the acid filling gun, ensures that the water-blocking ball's lifting and lowering action is smooth and reliable. While realizing automated acid filling, it significantly improves the service life of the equipment and the cleanliness of the working environment. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0023] like Figures 1 to 4As shown, this utility model provides a vacuum acid filling device for AGM battery trial production, including a frame 1, an acid filling base, an acid filling gun, and a conveyor belt 4. It also includes a vacuum tank 5 and an acid delivery pipe connected to the vacuum tank 5. The acid delivery pipe is connected to the acid filling gun. The lower part of the acid filling gun is provided with a flow guide joint 7, which has an internal cavity. The flow guide joint 7 is slidably connected to the acid filling gun. The bottom of the flow guide joint 7 has an acid outlet 71. A water-blocking ball 72 is provided inside the flow guide joint 7 to block the acid outlet 71. The water-blocking ball 72 is connected to a lifting device 8. The acid filling gun 3 is inserted into the flow guide joint 7, pushing the lifting device 8 to move the water-blocking ball 72 away from the acid outlet 71. The vacuum tank 5 is fixedly installed in the frame 1 and connected to the inlet of the acid filling gun through a metal acid delivery pipe. The top of the acid filling gun 3 is provided with a vacuum pump 31 interface to drive the extraction of acid from the vacuum tank 5. This utility model uses the conveyor belt 4 to transport the battery to be filled with acid. The battery is delivered to the acid filling station 2. A negative pressure acid suction system is formed by the vacuum filling station 5 and the acid delivery pipe, ensuring stable and efficient acid delivery. When the acid filling gun is inserted into the guide connector 7, its cooperation with the guide column 81 pushes the drive bar 83 downwards. The lifting rope 82 then links the water-blocking ball 72 upwards to open the acid outlet 71, enabling acid filling into the battery. As the acid filling gun rises, the water-blocking ball 72 automatically resets under gravity to seal the acid outlet 71, effectively solving the leakage problem of traditional vacuum acid filling devices used in AGM battery prototyping. The buffer device 9 on the outside of the guide connector 7 absorbs the impact of the acid filling gun and simultaneously presses the battery to ensure that the acid outlet 71 accurately aligns with the battery's acid storage tank. The through-slot structure of the guide column 81 and the sliding drive bar 83 design, combined with the guide column 81's inner diameter being the same as the acid filling gun's diameter, ensures smooth and reliable lifting and lowering of the water-blocking ball 72. This achieves automated acid filling while significantly improving the equipment's service life and the cleanliness of the working environment.

[0024] The flow guide connector 7 has an acid inlet, into which the acid filling gun is inserted. A buffer device 9 is provided on the outside of the flow guide connector 7, and the buffer device 9 is connected to the acid filling seat. The flow guide connector 7 is connected and fixed to the lower end of the acid filling gun through the buffer device. Its interior is a hollow cavity with a conical cavity at the bottom. An acid outlet 71 is provided at the bottom of the cavity. The water-blocking ball 72 is made of acid-resistant rubber and forms a line seal with the acid outlet 71 through the spherical surface. This connection method not only ensures the reliability of the seal, but also facilitates the disassembly and replacement of wear parts, greatly extending the service life of key components.

[0025] The lifting device 8 includes a guide post 81, a lifting rope 82, and a drive bar 83. The guide post 81 extends from the acid outlet 71 into the flow guide connector 7. A through groove is provided on one side of the guide post 81. The lifting rope 82 passes through the through groove from the guide post 81 and is connected to the water-blocking ball 72. The drive bar 83 is disposed inside the guide post 81 and slides along the inner wall of the guide post 81, and is connected to the lifting rope 82. The inner diameter of the guide post 81 is aligned with the acid outlet 71. The lifting rope 82 passes through the guide post 81, with one end connected to the water-blocking ball 72 and the other end connected to the drive bar 83. The drive bar 83 is a curved cylinder. The drive bar 83 can fit against the inner diameter of the guide post 81 and slide along the inside of the guide post 81, improving the smoothness of lifting.

[0026] The buffer device 9 includes side ears 91 symmetrically arranged on the periphery of the flow guide 7. Each side ear 91 has an upwardly extending sliding rod 92. The sliding rod 92 is slidably connected to the acid filling seat. A limiting block 93 is provided on the sliding rod 92 above the acid filling seat. Two symmetrical side ears 91 are welded to the outer wall of the flow guide 7. Each side ear 91 is connected to the guide rod on the acid filling seat through a linear bearing. The upper part of the guide rod is provided with a limiting block 93, and the lower part is fitted with a buffer spring 94. This floating connection design gives the flow guide 7 a buffer stroke of 3-5mm, which can absorb the impact and maintain a stable downward pressure. The limiting block 93 is a limiting nut, and the clamping force of the spring can be adjusted by adjusting the nut.

[0027] A lifting cylinder 21 is installed above the acid filling base, and the lifting cylinder is connected to the frame 1. The lifting cylinder 21 is mounted on the crossbeam of the frame 1 via a flange, and the end of the piston rod is connected to the acid filling base via a fisheye connector. Linear guide rails are provided on both sides of the cylinder to ensure smooth and wobbly lifting.

[0028] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
