Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing equipment, and in particular to a lithium battery encapsulation device. Background Technology

[0002] Flat lithium batteries, due to their small size, are often used in small portable rechargeable devices. In their manufacturing process, flat lithium batteries require sealing. Specifically, a moisture-proof and flame-retardant sealing sticker is affixed to the sides of the battery body, providing good protection. For effective protection, the sealing sticker must adhere tightly to the battery body. Air bubbles or misalignment will result in substandard finished batteries. Since the sealing sticker needs to cover all four sides of the battery, conventional sticker application equipment cannot achieve effective adhesion. Furthermore, the battery body cannot withstand severe impacts or vibrations, placing higher demands on automated sealing devices. Large manufacturers can use high-precision multi-axis robots for sealing, but this makes the equipment too expensive and difficult for small and medium-sized manufacturers to implement. Therefore, the sealing and pasting of lithium batteries still requires a large amount of manual labor to ensure the quality of the sealing. This requires high technical skills from the workers and also greatly increases the processing cost. Utility Model Content

[0003] The purpose of this utility model is to provide a lithium battery sealing device, specifically an automatic sealing device that can effectively seal lithium batteries.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a lithium battery sealing device, comprising a processing and conveying mechanism, a first top-feeding limiting mechanism, a second top-feeding limiting mechanism, and a pressing and bonding mechanism. The processing and conveying mechanism is provided with a sealing processing position. The first top-feeding limiting mechanism and the second top-feeding limiting mechanism are respectively located on both sides of the sealing processing position and are both located below the processing and conveying mechanism. Both the first top-feeding limiting mechanism and the second top-feeding limiting mechanism include a top-feeding driving mechanism and a top-feeding component. The pressing and bonding mechanism is provided above the sealing processing position. The pressing and bonding mechanism includes a pressing and bonding driving mechanism and a pressing and bonding component. The pressing and bonding driving mechanism can drive the pressing and bonding component to move left, right, up, and down on the sealing processing position.

[0005] Specifically, the processing and conveying mechanism adopts a conveying mechanism composed of multiple conveying rollers. The material lifting components of the first and second material lifting limiting mechanisms lift and limit the material upward from below the processing and conveying mechanism through the gap between the conveying rollers.

[0006] Specifically, the pressing and bonding component includes a mounting frame and a roller, the roller being rotatably connected below the mounting frame, and the pressing and bonding drive mechanism being drivenly connected to the mounting frame.

[0007] Specifically, the processing and conveying mechanism is also equipped with a sealing sticker limiting piece, which is located in the downward direction of the sealing processing position.

[0008] Specifically, the pressing and bonding drive mechanism includes a front and rear drive mechanism and a vertical drive mechanism. The front and rear drive mechanism is connected to the vertical drive mechanism, and the vertical drive mechanism is connected to the pressing and bonding component.

[0009] The beneficial effects of this invention are as follows: by setting a sealing processing position on the processing and conveying mechanism, and setting two top material limiting mechanisms below the processing and conveying mechanism to lift and limit the sealing sticker, and then using a pressing and bonding mechanism set above the sealing processing position to wrap and bond the sealing sticker to the lithium battery body, the overall structure of the sealing device is effectively designed for the characteristics of lithium battery sealing, and can realize automated, fast and effective sealing of lithium batteries, while also having a low overall cost. Attached Figure Description

[0010] Appendix Figure 1 This is a schematic diagram of the overall structure of the lithium battery packaging device in the embodiment. Detailed Implementation

[0011] Example 1, referring to Figure 1 A lithium battery sealing device includes a processing and conveying mechanism 1, a first top-feeding limiting mechanism 21, a second top-feeding limiting mechanism 22, and a pressing and bonding mechanism 3. The processing and conveying mechanism 1 is provided with a sealing processing position 11. The first top-feeding limiting mechanism 21 and the second top-feeding limiting mechanism 22 are respectively located on both sides of the sealing processing position 11 and are both located below the processing and conveying mechanism 1. The first top-feeding limiting mechanism 21 and the second top-feeding limiting mechanism 22 each include a top-feeding driving mechanism 23 and a top-feeding component 24. The pressing and bonding mechanism 3 is provided above the sealing processing position 11. The pressing and bonding mechanism 3 includes a pressing and bonding driving mechanism 31 and a pressing and bonding component 32. The pressing and bonding driving mechanism 31 can drive the pressing and bonding component 32 to move left, right, up, and down on the sealing processing position 11.

[0012] In this embodiment, the processing and conveying mechanism 1 is used to convey the sealing sticker 10. After conveying the sealing sticker 10 to the sealing processing position 11, the lithium battery body 20 is placed on the sealing sticker 10. Then, the first top material limiting mechanism 21 and the second top material limiting mechanism 22 push the sealing sticker 10 upward from both sides of the lithium battery body 20 so that the sealing sticker 10 stands upright along both sides of the lithium battery body 20. Then, the pressing and bonding driving mechanism 31 drives the pressing and bonding component 32 to move up, down, left and right above the lithium battery body 20, pressing and bonding the sealing sticker 10 that stands upright on both sides of the lithium battery body 20 to the upper surface of the lithium battery body 20, thereby realizing the sealing and processing of the lithium battery.

[0013] The first and second top-feed limiting mechanisms 21 and 22 are driven by the top-feed driving mechanism 23 to move the top-feed component 24 upwards to lift the sealing sticker 10. After lifting the sealing sticker 10, the top-feed limiting mechanism 22 restricts the sealing sticker 10 to both sides of the lithium battery body 20. In addition, to avoid the top-feed component 24 from impacting the lithium battery body 20 and to ensure that the top-feed component 24 can restrict the sealing sticker 10 to the side of the lithium battery body 20, the top-feed component 24 is made of a flexible metal sheet. In addition, the pressing and bonding driving mechanism 31 includes a front and rear driving mechanism 311 and a vertical driving mechanism 312. The front and rear driving mechanism 311 drives the vertical driving mechanism 312, which in turn drives the pressing and bonding component 32. The pressing and bonding driving mechanism 31 drives the pressing and bonding component 32 to move vertically and horizontally (i.e., up, down, left, and right) on the lithium battery body 20, thereby achieving effective bonding of the sealing sticker 10. Specifically, when placing the lithium battery body 20 onto the sealing sticker 10, it can be done manually or by using a conventional robotic arm with suction cups to pick up the lithium battery body and place it.

[0014] Specifically, the above-mentioned processing and conveying mechanism 1 adopts a conveying mechanism composed of multiple conveying rollers. The material lifting component 24 of the first material lifting limiting mechanism 21 and the second material lifting limiting mechanism 22 lifts and limits the material upward from below the processing and conveying mechanism 1 through the gap between the conveying rollers.

[0015] Specifically, in this embodiment, the pressing and bonding component 32 includes a mounting frame 321 and a roller 322. The roller 322 is rotatably connected to the underside of the mounting frame 321, and the pressing and bonding drive mechanism 31 is drivenly connected to the mounting frame 321. The roller 322 allows the sealing sticker 10 to be tightly bonded to the lithium battery body 20, while avoiding scratches and damage to the sealing sticker 10, thus improving the sealing quality.

[0016] Specifically, the aforementioned processing and conveying mechanism 1 is also equipped with a sealing sticker limiting piece 4, which is located in the downward direction of the sealing processing position 11. By setting the sealing sticker limiting piece 4, the position of the sealing sticker 10 can be limited. After the sealing sticker 10 moves to the sealing sticker limiting piece 4, it is limited and thus facilitates accurate positioning of the sealing sticker 10 and improves the sealing quality.

[0017] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
