Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a battery core high-voltage static placement mechanism. Background Art

[0002] A battery is a small device that can generate stable voltage and current, supply power for a long time, and is less affected by the outside world. In modern society, batteries play an important role. In the production process of lithium batteries, standing is a very critical step. Standing refers to the process of allowing the various materials and electrolytes inside the battery cell to fully penetrate and balance after the injection is completed. By standing, it can ensure that the contact between the various components in the battery cell is sufficient and the electrolyte is evenly distributed, thereby improving the performance and stability of the battery. A certain standing time can effectively improve the cycle life and safety of the battery, and is an important part of ensuring battery quality.

[0003] The current single static mechanism cannot complete a large number of static tasks in a short period of time, which leads to low production efficiency and the inability to achieve rapid production of batteries. Therefore, the method of adding multiple static stations is often used to solve this defect, but this method is also accompanied by the following defects. Multiple static stations will take up more space and supporting facilities, and have higher requirements for the site; the production input of equipment and labor costs increases, and additional costs for manual maintenance and overhaul are required; the complexity and difficulty of managing multiple static stations increase. At the same time, current battery static devices often use rotation, tilting, and vibration methods to improve the infiltration effect of the electrolyte, and these methods have the following disadvantages: there is still a small amount of space in the battery cell that is not filled with electrolyte, resulting in reduced battery capacity, unstable performance, shortened life and safety hazards; gas reactions and leakage may occur; the long static time of these methods will slow down the production rhythm and affect production capacity and production efficiency.

[0036] A z-axis pressing assembly 3, which is connected to the static chamber 1 to drive the static chamber 1 to move toward or away from the battery clamp 2;

[0037] The supporting body 4 plays a supporting and fixing role.

[0038] Preferably, a clamping plate 6 is installed at the lower end of the static chamber 1 , and a sealing ring 7 is installed on the clamping plate 6 .

[0039] Preferably, the support body 4 includes an upper support seat 21, a connecting plate 22 and a support frame 23. A connecting plate 1 24 is provided at the bottom of one side of the upper support seat 21, and a connecting plate 2 25 is provided at the bottom of the other side; the connecting plate 1 24 is installed with the support frame 1 26, and the connecting plate 2 25 is installed with the support frame 2 27. The support frame 23 includes a pillar 1 28, one end of the pillar 1 28 is connected to a pillar 2 29, a foot pier 32 is installed on the pillar 2 29, the other end of the pillar 1 28 is connected to a pillar 3 30, a foot pier 32 is installed on the pillar 3 30, and a pillar 4 31 is connected between the pillar 2 29 and the pillar 3 30. The z-axis pressing assembly 3 includes a guide rod cylinder 10, the guide rod cylinder 10 is installed on the upper support seat 21, and the guide rod 20 of the guide rod cylinder 10 is connected to the static cavity 1. The z-axis pressing assembly 3 also includes a guide post 11 and a guide post connecting block 12; one end of the guide post 13 and the guide post 2 14 is connected to the guide post connecting block 15, and the other end is connected to the static cavity 1; one end of the guide post 3 16 and the guide post 4 17 is connected to the guide post connecting block 2 18, and the other end is connected to the static cavity 1. A linear bearing 19 is installed on the guide post 11.

[0040] Preferably, the battery clamp 2 is provided with a liquid filling cup 9 , and the liquid filling cup 9 is located at a corresponding position above the battery placement position 8 .

[0041] Preferably, if Figure 5-Figure 6 As shown, in this embodiment, the battery clamp 2 can be positioned in various ways, such as using a guide rail 33 for movement and positioning, or using a supporting and fixing assembly 34 for positioning.

[0042] The above technical solution realizes the process of static and secondary liquid injection through the following steps. First, the supporting body 4 provides structural stability and bearing capacity for the static cavity 1 and the z-axis pressing assembly 3, and uses the guide rail 33 or the supporting fixing assembly 34 to position the battery fixture 2 to the corresponding position of the static cavity 1. Then the z-axis pressing assembly 3 presses down the static cavity 1 through the cooperation of the guide column 12, the linear bearing 19 and the guide rod cylinder 10, so that the static cavity 1 and the battery fixture 2 are sealed and matched to form an environment that is not affected by the outside air. Then the gas is filled into the static cavity 1 through the pressure tube 5 to increase the pressure so that the electrolyte in the injection cup 9 can be injected into the battery already filled with electrolyte for a second time. Finally, the gas is evacuated to fully remove the gas inside the battery cell, so that the electrolyte can be fully diffused to every dead corner in the steel shell cell.

[0043] The utility model has made a brand-new design for the breathing static mechanism and made a bold attempt. The static cavity 1 is used to isolate the incoming battery cell from the outside air. The internal cavity pressure is controlled by filling and evacuating the gas into the static cavity 1, and the gas inside the cell is fully removed, so that the electrolyte is fully diffused to every dead corner in the steel shell cell, which greatly improves the battery performance and reliability. The static cavity 1 has a simple structural design, and the manual maintenance time and cost are reduced. The preferred specific implementation process can be to push the static cavity 1 downward by a cylinder to cover the incoming material fixture to isolate the external gas, and then pass high-pressure gas 0.1MPa into the static cavity 1 to press the electrolyte of the injection cup 9 into the cell, and then evacuate the cavity gas to quickly remove the gas inside the cell, so that the electrolyte can fully infiltrate the cell, and ensure that the electrolyte is evenly mixed and electrolyzed, so as to improve the injection efficiency and performance stability.

[0044] The design concept of the utility model is: by establishing high-pressure conditions, the electrolyte inside the injection cup is compressed into the battery core to ensure that the amount of liquid filled into the battery meets the standard, and then by establishing low-pressure conditions, the gas in the cavity is evacuated, so that all the gas in the battery is extracted, and the bubbles inside the battery are dissolved in a vacuum environment, which is conducive to the uniform distribution of the electrolyte and improves the efficiency of injection and performance stability. In addition, by preventing external air from entering, the internal pressure of the battery can be controlled, and the electrolyte can be distributed more evenly and stably inside the battery. It has the characteristics of high automation and integration, and can quickly complete the static process and improve production efficiency. It can effectively avoid gas reactions and leakage that may occur inside the battery, and to a certain extent, improve the battery life. The specific effects of the specific implementation process are: 1. Simple structure, reducing manual maintenance costs and time; 2. High production efficiency, and can simultaneously static large quantities of batteries; 3. It can effectively avoid gas reactions and leakage that may occur inside the battery, and improve battery performance.
