Description

Technical Field

[0001] This utility model relates to the field of battery infusion technology, and in particular to an electrode fluid infusion structure for a sodium-ion battery without a negative electrode. Background Technology

[0002] Electrode fluid is a key component of a negative electrode-free sodium-ion battery. It typically consists of a sodium salt dissolved in a suitable organic solvent. The choice of sodium salt is crucial; common choices include sodium perchlorate and sodium hexafluorophosphate, as different sodium salts affect the transport performance of sodium ions and the overall electrochemical performance of the battery. For organic solvents, carbonates are often chosen, as they must possess good chemical stability and a suitable dielectric constant to ensure the smooth movement of sodium ions within them.

[0003] The electrode fluid plays a crucial role. On the one hand, it provides a transport channel for sodium ions, allowing them to shuttle back and forth between the positive and negative electrodes to achieve the charging and discharging process. On the other hand, its characteristics also affect the battery's safety and cycle life.

[0004] However, existing battery electrolyte filling machines are often inconvenient to replace the filling head. When a replacement is needed, workers must spend considerable time and effort disassembling and reassembling the machine, which is extremely inconvenient. Furthermore, the overall stability of the battery during electrolyte filling is poor, making the battery prone to shaking and displacement. This not only affects the accuracy of the filling but may also pose safety hazards, hindering the efficient and safe operation of battery electrolyte filling. To address these technical problems, this application proposes a negative electrode-free sodium-ion battery electrode electrolyte delivery structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-negative electrode sodium-ion battery electrode liquid infusion structure. During operation, the battery is placed on the placement box, and the servo motor is started via the control panel. This motor drives the first connecting block to rotate, which in turn moves the second connecting block, thereby pulling the slider along the limiting rod. This causes the top clamping plate to move synchronously and clamp the battery, thus preventing the battery from shaking or shifting during liquid injection and improving the accuracy of liquid injection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A negative electrode-free sodium-ion battery electrode liquid delivery structure includes a placement box. Two clamping plates are slidably connected to the top of the placement box, and the bottoms of the two clamping plates are connected by a clamping assembly to adjust the distance between the two clamping plates. A robotic arm is fixedly connected to the rear side of the placement box, and a connecting plate is fixedly connected to the front side of the robotic arm. A connecting block is inserted into the inner wall of the connecting plate. Limiting blocks are slidably connected to the top and bottom sides of the inner wall of the connecting plate. The right sides of the two limiting blocks abut against the left side of the connecting block. The inner walls of the two limiting blocks are connected by a limiting assembly to control the distance between the two limiting blocks. An injection head is fixedly connected to the front side of the connecting block, and an injection tube is sleeved on the front side of the connecting plate. The bottom of the injection tube is threadedly connected to the top of the injection head.

[0007] Furthermore, the clamping assembly includes a slider fixedly connected to the bottom of the clamping plate, a second connecting block rotatably connected to the bottom of the slider, and a first connecting block rotatably connected to the bottom of the placement box.

[0008] Furthermore, the outer wall of the slider is slidably connected to the bottom side of the inner wall of the placement box, and the top left and right sides of the first connecting block are rotatably connected to the bottom sides of the two second connecting blocks.

[0009] Furthermore, a servo motor is fixedly connected to the front side of the placement box, and a control panel is fixedly connected to the front side of the placement box. The bottom end of the first connecting block is fixedly connected to the drive end of the servo motor.

[0010] Furthermore, a limiting rod is fixedly connected to the inner wall of the placement box, and the inner wall of the slider is slidably connected to the outer wall of the limiting rod.

[0011] Furthermore, the limiting component includes a bidirectional screw rotatably connected to the inner wall of the connecting plate, the outer wall of the bidirectional screw being threadedly connected to the inner wall of the limiting block, a worm gear being fixedly connected to the outer wall of the bidirectional screw, and a worm being meshed with the right side of the outer wall of the worm gear.

[0012] Furthermore, a sliding rod is fixedly connected to both the top and bottom sides of the inner wall of the connecting plate, the outer wall of the sliding rod is slidably connected to the left side of the limiting block, and a knob is fixedly connected to the front end of the worm gear.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when working, the battery is placed on the placement box, and the servo motor is started through the control panel. It drives the first connecting block to rotate, which drives the second connecting block to move, thereby pulling the slider along the limit rod, so that the top clamping plate moves synchronously and clamps the battery; thus avoiding shaking and displacement of the battery during liquid injection, thereby improving the accuracy of liquid injection.

[0014] 2. In this utility model, during replacement, first unscrew the injection tube from the injection head, turn the knob to rotate the worm gear, and drive the bidirectional screw to rotate through the worm gear engagement, allowing the limit stop to slide along the slide bar to release the limit on the connecting block, thus removing the old injection head; when installing the new injection head, insert the connecting block back into the connecting plate, rotate the knob in the opposite direction to make the limit stop clamp the connecting block, and then screw on the injection tube. No complicated disassembly steps are required, allowing workers to quickly complete the replacement, adapting to the electrolyte filling needs of different battery specifications, and improving the flexibility and efficiency of equipment use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 and Figure 2This utility model provides an embodiment of a negative electrode-free sodium-ion battery electrode liquid infusion structure, including a placement box 1. Two clamping plates 2 are slidably connected to the top of the placement box 1, and sliders 9 are fixedly connected to the bottom of the clamping plates 2. The two clamping plates 2 at the top of the placement box 1 are slidable, and the sliders 9 at the bottom can drive the clamping plates 2 to move. In conjunction with other components, the distance between the two clamping plates 2 can be adjusted to stably clamp the battery. A second connecting block 12 is rotatably connected to the bottom of the slider 9, and a first connecting block 11 is rotatably connected to the bottom of the placement box 1. The outer wall of the slider 9 is slidably connected to the bottom side of the inner wall of the placement box 1. The top left and right sides of the first connecting block 11 are rotatably connected to the sides of the bottoms of the two second connecting blocks 12. The slider 9 and the placement box 1 are rotatably connected to each other. The bottom side of the inner wall of the placement box 1 slides to guide the movement of the clamping plate 2; the first connecting block 11 and the second connecting block 12 are rotatably connected, which can convert the rotation of the first connecting block 11 and the movement of the second connecting block 12 into the sliding of the slider 9, thereby adjusting the distance between the two clamping plates 2; a servo motor 8 is fixedly connected to the front side of the placement box 1, and a control panel 7 is fixedly connected to the front side of the placement box 1. The servo motor 8, the robotic arm 3 and the injection head 5 are started through the control panel 7; the bottom end of the first connecting block 11 is fixedly connected to the drive end of the servo motor 8, and the servo motor 8 drives the first connecting block 11 to rotate; a limit rod 10 is fixedly connected to the inner wall of the placement box 1, and the inner wall of the slider 9 is slidably connected to the outer wall of the limit rod 10, so that the slider 9 can slide stably; Reference Figure 1 , Figure 3 and Figure 4 A robotic arm 3 is fixedly connected to the rear of the placement box 1. It mainly consists of a control system, a drive system, an actuator, and a sensing system. The control system receives commands, the drive system provides power, the actuator performs specific actions, and the sensing system provides feedback. Its working principle is to precisely control the movement trajectory and actions of the robotic arm 3 according to commands through the coordination of various systems, thereby achieving the predetermined task. A connecting plate 4 is fixedly connected to the front of the robotic arm 3. A connecting block 14 is inserted into the inner wall of the connecting plate 4. The robotic arm 3 drives the connecting plate 4 to move, thereby moving the connecting block 14 and the injection head 5. Limiting blocks 13 are slidably connected to the top and bottom sides of the inner wall of the connecting plate 4. The right sides of the two limiting blocks 13 abut against the left side of the connecting block 14, limiting the connection block 14. A bidirectional screw 15 is rotatably connected to the inner wall of the connecting plate 4. The outer wall of the bidirectional screw 15 is threadedly connected to the inner wall of the limiting blocks 13. The rotation of the bidirectional screw 15 drives the limiting blocks 13. Block 13 slides; a worm gear 18 is fixedly connected to the outer wall of the bidirectional screw 15, and a worm 19 is meshed with the right side of the outer wall of the worm gear 18. The rotation of the worm 19 meshes with the worm gear 18, causing the worm gear 18 to drive the bidirectional screw 15 to rotate; a slide rod 16 is fixedly connected to the top and bottom sides of the inner wall of the connecting plate 4, and the outer wall of the slide rod 16 is slidably connected to the left side of the limiting block 13, so that the limiting block 13 slides stably; a knob 17 is fixedly connected to the front end of the worm 19, and an injection head 5 is fixedly connected to the front side of the connecting block 14 for infusing the battery; an injection tube 6 is sleeved on the front side of the connecting plate 4, and the bottom of the injection tube 6 is threadedly connected to the top of the injection head 5 to input battery fluid into the injection head 5.

[0019] Working principle: When starting work, place the battery on the placement box 1, start the servo motor 8 through the control panel 7, so that the servo motor 8 drives the first connecting block 11 to rotate. The rotation of the first connecting block 11 drives the second connecting block 12 to move, thereby pulling the two sliders 9 to slide. The sliding of the sliders 9 drives the clamping plate 2 to slide to clamp the battery.

[0020] The robotic arm 3 and injection head 5 are activated via control panel 7 to administer intravenous fluid to the battery. When injection head 5 needs to be replaced to accommodate different battery sizes, the injection tube 6 is unscrewed from injection head 5. Rotating knob 17 causes worm gear 19 to rotate, which in turn engages with worm wheel 18, causing worm wheel 18 to drive bidirectional screw 15 to rotate. The rotation of bidirectional screw 15 causes limit stop 13 to slide and release the limit on connecting block 14, allowing connecting block 14 to be removed from connecting plate 4, thus removing injection head 5. During installation, connecting block 14 is inserted back into its original position, and knob 17 is rotated in the opposite direction to cause the two limit stops 13 to slide and limit connecting block 14. The injection tube 6 is then screwed onto injection head 5.
