Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of lithium battery assembly auxiliary device technology, and more specifically, to a lithium battery fixing device. Background Technology

[0002] In the field of lithium battery applications, the mounting device for lithium battery packs is a crucial component for ensuring stable battery performance and safe use. However, traditional lithium battery mounting devices suffer from numerous technical bottlenecks when arranging and connecting lithium batteries, severely impacting the assembly efficiency and reliability of lithium battery packs.

[0003] Existing lithium battery fixing devices have significant shortcomings in terms of splicing and clamping. During the process of arranging and fixing lithium batteries together, manual splicing is mostly relied upon. This method is not only cumbersome but also makes it difficult to precisely control the splicing force. Due to the limitations of manual splicing, gaps are easily left between lithium batteries, resulting in a loose battery pack structure. For example, when assembling a lithium battery pack, operators need to adjust and fix the position of each lithium battery individually, which is not only time-consuming and labor-intensive but also makes it difficult to ensure the tightness of the splicing between each lithium battery.

[0004] Furthermore, after manual assembly, secondary processing using pressure equipment is often required to fill gaps, which undoubtedly increases production steps and time costs, leading to overall inefficiency. Simultaneously, improper pressure control during secondary processing can damage lithium batteries, affecting their performance and lifespan. In addition, traditional fixing devices lack effective automatic clamping mechanisms and cannot adapt to the assembly needs of lithium batteries of different specifications and quantities. When faced with diverse lithium battery assembly tasks, frequent changes or adjustments to the fixing device structure are necessary, further reducing production efficiency.

[0005] With the rapid development of new energy technologies, lithium batteries are increasingly widely used in energy storage systems and other fields, placing higher demands on the assembly efficiency and quality of lithium battery packs. Traditional fixing devices, due to problems such as "difficult splicing, numerous gaps, and low efficiency," can no longer meet the needs of large-scale, high-efficiency lithium battery production. Therefore, there is an urgent need to develop a fixing device that can automatically splice and press lithium batteries together, reduce gaps, and improve assembly efficiency, in order to solve the industry pain points of "low efficiency of manual splicing and high secondary processing costs," and promote the advancement of lithium battery application technology.

[0035] like Figures 1-4 As shown, a lithium battery fixing device according to an embodiment of the present disclosure is illustrated, comprising:

[0036] A platform 1 and a movable frame 2, wherein the movable frame 2 is mounted on the platform 1;

[0037] Centering positioning component 5, which is disposed on the platform 1 and the movable frame 2;

[0038] A pair of lithium battery packs 3 and a docking sleeve 6, wherein the lithium battery packs 3 are mounted on the platform 1 and the docking sleeve 6 is fitted between the pair of lithium battery packs 3;

[0039] A movable extrusion assembly 4 is disposed between the sleeve and the movable frame 2;

[0040] The movable extrusion assembly 4 includes a pair of slide rails 4-1, which are disposed at both ends of the bottom of the frame 1. The movable frame 2 is slidably connected to the slide rails 4-1. A drive screw 4-2 is disposed at the bottom of the frame 1. The drive screw 4-2 is connected to the movable frame 2 by a threaded connection. A pressure plate 4-3 is disposed on the movable frame 2. A pair of telescopic cylinders 4-4 are mounted on the movable frame 2. The output end of the telescopic cylinders 4-4 is connected to the pressure plate 4-3. A drive motor 4-5 is installed on one side of the frame 1. A transmission gear 4-6 is disposed at the output end of the drive motor 4-5 and at one end of the drive screw 4-2. The transmission gears 4-6 mesh with each other.

[0041] In some examples, a moving extrusion assembly 4 is designed to achieve continuous pressing of multiple lithium battery packs 3. This assembly uses slide rails 4-1 at both ends of the bottom of the stand 1 as a guide structure. The moving frame 2 is slidably connected to the slide rails 4-1 via a slider to ensure smooth and stable movement. The drive screw 4-2 at the bottom of the stand 1 is driven to rotate by the drive motor 4-5 through the transmission gear 4-6, which engages with the threaded hole of the moving frame 2, causing the moving frame 2 to reciprocate linearly along the slide rails 4-1. When it is necessary to press the lithium battery pack 3, the drive motor 4-5 rotates, causing the drive screw 4-2 to rotate. The moving frame 2 moves to the surface of the lithium battery pack 3, and the telescopic cylinder 4-4 on the moving frame 2 is activated, pushing the pressure plate 4-3 downward to apply pressure to the lithium battery pack 3 and complete the pressing operation. Subsequently, the telescopic cylinder 4-4 retracts, and the drive motor 4-5 reverses to move the moving frame 2 above the next set of lithium battery packs 3, repeating the pressing action.

[0042] Through the transmission of the drive screw 4-2, the pressure control of the telescopic cylinder 4-4, and the power transmission of the transmission gear 4-6, the moving extrusion assembly 4 realizes the continuous and automated pressing of multiple lithium battery packs 3, effectively improving work efficiency.

[0043] like Figures 1-4 As shown in the figure, the centering positioning component 5 proposed in this embodiment includes several elongated holes 5-1. The elongated holes 5-1 are respectively opened at the four opposite corners of the side surface of the platform 1 and the side surface of the movable frame 2 and the pressure plate 4-3. A stabilizing rod 5-2 is provided in each of the elongated holes 5-1 on the platform 1. A positioning post 5-3 is slidably fitted on the stabilizing rod 5-2. The other end of the positioning post 5-3 passes through the elongated hole 5-1 on the movable frame 2. One end of the positioning post 5-3 is connected to a pair of supporting studs 5-4 by threaded connection. A stabilizing block 5-5 is provided at one end of the supporting studs 5-4.

[0044] In some examples, to ensure the lithium battery remains centered during the fixing process and to accommodate lithium batteries of different widths, a centering positioning component 5 is designed. This component uses elongated holes 5-1 at the four corners of the side surfaces of the stand 1, the movable frame 2, and the pressure plate 4-3 as the mounting base. A stabilizing rod 5-2 within the elongated hole 5-1 provides a sliding guide for the positioning post 5-3. The positioning post 5-3 can slide freely along the stabilizing rod 5-2 within the elongated hole 5-1. It is fixed in place by rotating the support studs 5-4 at both ends to engage with the stabilizing blocks 5-5, thereby changing the distance between the two positioning posts 5-3 to accommodate lithium batteries of different widths. After placing the lithium battery on the stand 1, the position of the positioning post 5-3 is adjusted to fit against both sides of the lithium battery, fixing it in a centered position and preventing displacement during the pressing process.

[0045] By adjusting the sliding of the positioning post 5-3, tightening the support stud 5-4, and limiting the position of the stabilizing block 5-5, the centering positioning component 5 achieves flexible positioning adjustment according to the width of the lithium battery and ensures that the lithium battery is always kept in the center position, providing a reliable guarantee for the stable pressing of the lithium battery.

[0046] For example, such as Figure 2 As shown, the surface of the platform 1 is a sunken structural surface, and a boss 7 is provided in the surface of the platform 1, with the boss 7 located in the center of the platform 1.

[0047] In some examples, the bottom of the lithium battery pack 3 is supported by the boss 7, leaving the two bottom corners suspended, which facilitates the connection of the docking sleeve 6.

[0048] For example, as shown in Figure 1, the docking sleeve 6 has an overall X-shaped structure, and the docking sleeve 6 wraps around the four corners of the lithium battery pack 3.

[0049] In some examples, the X-shaped structure allows the docking sleeve 6 to completely enclose all four corners of the lithium battery pack 3, providing protection.

[0050] For example, such as Figure 2 As shown, connecting rods 8 are provided at the four opposite corners of the surface of the pressure plate 4-3, and one end of the connecting rod 8 is movably fitted into the movable frame 2.

[0051] In some examples, the connecting rod 8 can help the pressure plate 4-3 maintain uniform pressure when pressure is applied.

[0052] For example, such as Figure 4 As shown, a pair of support studs 5-4 are distributed on the upper and lower sides of the elongated hole 5-1, and the contact surface between the stabilizing block 5-5 and the frame 1 is an anti-slip structural surface with high friction.

[0053] In some examples, the anti-slip structural surface makes the stabilizing block 5-5 fit more firmly against the surface of the frame 1.

[0054] In actual use: Fix the frame 1, place the lithium battery pack 3 on the protrusion 7 on the sunken structural surface of the frame 1, and the docking sleeve 6 wraps around the four corners of the lithium battery pack 3. The drive motor 4-5 drives the drive screw 4-2 to rotate through the transmission gear 4-6, so that the moving frame 2 moves along the slide rail 4-1 to the surface of the lithium battery pack 3. The telescopic cylinder 4-4 pushes the pressure plate 4-3 down. The pressure plate 4-3 is balanced by the connecting rod 8 and applies pressure to the lithium battery pack 3. The stabilizing rod 5-2 of the centering positioning component 5 passes through the long hole 5-1 of the frame 1. The positioning column 5-3 slides along the stabilizing rod 5-2 to adjust the spacing and is then fixed by the support stud 5-4 and the stabilizing block 5-5 to center the lithium battery pack 3. The moving extrusion component 4 drives the pressure plate 4-3 to complete the pressing, without the need to manually adjust the position of each lithium battery.
