Description

Technical Field

[0001] This utility model relates to the technical field of battery solution extrusion equipment, specifically a battery solution extrusion device. Background Technology

[0002] Battery solution generally refers to the liquid or ionic solution that acts as an ionic conductor in a battery. It allows charge transfer between the positive and negative electrodes, thereby enabling energy storage and release. Battery solution plays a crucial role in battery technology, and its performance directly affects the battery's efficiency, safety, and lifespan. With continuous technological advancements, research and development of battery solutions will continue to deepen to meet increasing energy demands and safety standards. Therefore, a battery solution extrusion device is needed. This device typically refers to equipment used in the battery production process to inject electrolyte into the battery or to pressurize the battery.

[0003] In existing technologies, battery solution extrusion equipment generally includes components such as a cell tray, a vacuum chamber, an injection head, an elastomer hose, an upper pressure roller, a lower pressure roller, a metering cup, an vent, and an inlet. During operation, the battery cells are first placed on the cell tray, and a vacuum is created inside the battery to form a negative pressure. Then, the injection head injects the electrolyte into the battery. Finally, the upper and lower pressure rollers squeeze the elastomer hose, ensuring the electrolyte is evenly distributed inside the battery.

[0004] However, when the above-mentioned device is in use, the electrolyte will generate certain bubbles as it flows through the injection head. These bubbles will enter the battery cell along with the electrolyte, which will reduce the battery's energy density to some extent. The presence of bubbles will occupy a certain space, preventing the electrolyte from fully filling the battery, resulting in a decrease in the battery's energy storage capacity, a shortened driving range, and a reduction in the battery's production quality.

[0005] Therefore, this utility model provides a battery solution extrusion device. Utility Model Content

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.

[0030] Please see Figure 1-6 A battery solution extrusion device includes a machine base 1, a mounting frame 2 fixedly connected to the top of the machine base 1, an infusion hose 3 fixedly connected to one side of the mounting frame 2, the infusion hose 3 being connected to the infusion mechanism body of the device, an infusion head 4 fixedly connected to the discharge end of the infusion hose 3, an antifoaming mechanism provided on the top of the machine base 1, a defoaming mechanism provided above the antifoaming mechanism, and a drainage mechanism provided at the bottom of the infusion head 4.

[0031] The defoaming mechanism includes two symmetrically distributed connecting blocks 5. The connecting blocks 5 are fixed to the mounting bracket 2 by a support rod. The top of the connecting blocks 5 is provided with a T-shaped connecting groove 6. The inner wall of the connecting groove 6 is slidably connected to a T-shaped striking plate 7. The side of the striking plate 7 near the injection head 4 is fixedly connected to a striking head 9. The top of the striking plate 7 is fixedly connected to a positioning plate 8.

A positioning roller 19 is rotatably connected to the inner wall of the positioning frame 18 through a bearing. The positioning roller 19 is in contact with the surface of the infusion tubing 3.

[0037] Specifically, the connecting rod 17 can slide within the inner wall of the connecting port 16, causing the positioning roller 19 to squeeze the infusion tubing 3, which can eliminate air bubbles in the electrolyte inside the infusion tubing 3, further ensuring the production quality of the battery.

[0038] As a further improvement of this utility model, a connecting plate 20 is fixedly connected to the side of the connecting rod 17 away from the infusion tubing 3, and a number of evenly distributed connecting springs 21 are fixedly connected to one side of the connecting plate 20.

[0041] Specifically, when the output shaft of the rotating motor 13 rotates, the rotating shaft 22 rotates, the rotation of the rotating shaft 22 causes the cam 23 to rotate, and the rotation of the cam 23 applies force to the connecting plate 20.

[0042] As a further improvement of this utility model, a fixing rod 24 is fixedly connected to one side of the mounting bracket 2, and an electric hydraulic rod 25 is fixedly connected to the bottom of the fixing rod 24. The piston rod of the electric hydraulic rod 25 is fixed to the injection head 4. An adjusting plate 26 is hinged to the inner wall of one side of the mounting bracket 2, and an adjusting spring 27 is fixedly connected to the top of the adjusting plate 26.

[0043] Specifically, the electric hydraulic rod 25 can move the infusion tubing 3 when the piston rod moves, and the elastic force of the adjusting plate 26 and the adjusting spring 27 can keep the infusion tubing 3 in a straight state.

[0044] As a further improvement of this utility model, the top of the adjusting plate 26 is provided with an adjusting groove, and the inner wall of the adjusting groove is rotatably connected to a protective roller 28 through a bearing.

[0045] As a further improvement of this utility model, the diversion mechanism includes a support plate 29 fixed to the inner wall of the injection head 4. A diversion block 30 is fixedly connected to the bottom of the support plate 29. The diversion block 30 has a conical structure and the bottom surface area of ​​the diversion block 30 is larger than the top surface area. The diversion block 30 allows the electrolyte to flow down the battery cell shell wall.

[0046] Specifically, the set flow guide block 30 allows the electrolyte to flow to the wall of the cell casing, which can prevent the electrolyte from splashing inside the cell casing wall, thereby reducing the amount of bubbles generated and ensuring the production quality of the battery.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0048] The working principle of this utility model is as follows: When the electrolyte is delivered through the infusion hose 3 and the injection head 4, starting the rotating motor 13 causes the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 causes the rotating disk 10 to rotate, which in turn causes the rotating rod 11 to rotate. The rotation of the rotating rod 11 applies force to the rotating groove 12, which causes the positioning plate 8 to move the striking plate 7 within the inner wall of the connecting groove 6. The movement of the striking plate 7 can strike the wall of the injection head 4. To protect the equipment, the surface of the striking head 9 can be coated with silicone. With the striking operation of the striking head 9, the air bubbles in the electrolyte inside the injection head 4 can be removed by vibration. Therefore, as the electrolyte is injected, the residual air bubbles can be reduced, the energy storage capacity of the battery can be improved, and the production quality of the battery can be guaranteed.

[0049] When the output shaft of the rotating motor 13 rotates, the rotating shaft 22 rotates. The rotation of the rotating shaft 22 causes the cam 23 to rotate. The rotation of the cam 23 applies force to the connecting plate 20 and squeezes the connecting spring 21. At this time, the connecting rod 17 can slide in the inner wall of the connecting port 16 and cause the positioning roller 19 to squeeze the infusion tubing 3. This can eliminate the air bubbles in the electrolyte in the infusion tubing 3 and further ensure the production quality of the battery.

[0050] When performing the injection operation, activating the electric hydraulic rod 25 can move the infusion tubing 3 when the piston rod moves. With the help of the elastic force of the adjusting plate 26 and the adjusting spring 27, the infusion tubing 3 can be kept in a straight state to facilitate the defoaming operation of the tapping head 9 and the positioning roller 19.

[0051] As the electrolyte flows down through the injection head 4, it can flow through the guide block 30 to the wall of the cell casing, which can prevent the electrolyte from splashing inside the cell casing wall, thereby reducing the amount of bubbles generated and ensuring the production quality of the battery.
