Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a quick-release side-suction dust collection structure. Background Technology

[0002] In lithium-ion battery manufacturing, tabs on the electrode sheets can be obtained through tab welding or laser cutting. Specifically, tab welding refers to welding tabs onto the electrode sheet material using ultrasonic welding. However, due to factors such as process quality and incoming material quality, the reliability of tab welding is relatively low, sometimes affecting battery performance and leading to a low product qualification rate. Laser cutting of tabs involves using a laser head to cut the shape of the tabs in the blank area of ​​the electrode sheet material. Compared with ultrasonically welded tabs, the tabs obtained by this process are not only more firmly connected but also have better conductivity, effectively ensuring battery performance. However, the laser cutting process generates dust. If this dust adheres to the electrode roll and is carried into subsequent processes, or even gets caught inside the battery, it can easily puncture the separator paper inside the cell, causing a micro-short circuit or even leading to battery explosions and other safety hazards. To address the aforementioned issues, a dust removal mechanism is typically added next to the laser cutting mechanism to adsorb dust. However, the dust generated by the electrode sheets is mostly composed of easily sticky substances such as ceramic powder, which often cannot be completely adsorbed by the dust removal mechanism and instead adheres to the inner wall of the cutting cavity. This significantly weakens the dust removal capability, requiring frequent cleaning of the dust removal mechanism. When cleaning the dust removal mechanism, the entire mechanism needs to be disassembled for cleaning, which not only takes a long time but also requires readjustment of the dust removal mechanism, greatly affecting the production efficiency of the battery cells. Utility Model Content

[0003] The main purpose of this utility model is to provide a quick-release side suction structure to solve the above-mentioned technical problems. It uses magnetic attraction to make the cutting cavity and the side suction port relatively fixed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick-release side-suction structure includes a mounting plate, a cutting cavity, a side suction port, a buckle, and a flange. The mounting plate is fixed to the cutting cavity, the side suction port is fixed to the flange, the flange is magnetically fixed to the mounting plate, the buckle is installed between the flange and the mounting plate, a magnet is provided on the flange, the flange is square-shaped, and multiple magnets are arranged in an orderly manner along the edge of the end face of the flange.

[0006] As a preferred technical solution, the buckle includes a handle, a pull buckle, and a locking hook. The handle is hinged to the mounting plate, the locking hook is fixed to the flange, the pull buckle is rotatably mounted on the handle, and the pull buckle abuts against the locking hook.

[0007] As a preferred technical solution, it further includes a support plate, which is fixed to the lower side of the mounting plate.

[0008] As a preferred technical solution, the support plate is provided with a slot, and the flange is placed in the slot.

[0009] The beneficial effects of this utility model are as follows: In the above-mentioned quick-release side suction structure, the flange is magnetically fixed to the mounting plate, thereby making the cutting cavity and the side suction port relatively fixed. The buckle is used to lock the flange in the mounting plate to strengthen the fixation between the flange and the mounting plate and prevent the flange from detaching from the mounting plate. The side suction port is connected to negative pressure, so that the dust generated during cutting passes through the cutting cavity and is absorbed and collected by the side suction port. During installation, the flange is placed on the support plate and then the buckle is operated to lock it, thereby realizing the relative fixation between the cutting cavity and the side suction port, so as to facilitate the disassembly and assembly of the side suction port, improve the cleaning efficiency of the dust removal mechanism, and thus improve the production efficiency of the battery cell. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the quick-release side-suction structure involved in this utility model. Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] like Figure 1 As shown, a quick-release side-suction structure includes a mounting plate 2, a cutting cavity 1, a side suction port 4, a buckle 5, a flange 3, and a support plate 6. The mounting plate 2 is fixed to the cutting cavity 1, and the side suction port 4 is fixed to the flange 3. The flange 3 is magnetically fixed to the mounting plate 2, thereby forming a relatively fixed relationship between the cutting cavity 1 and the side suction port 4. The buckle 5 is installed between the flange 3 and the mounting plate 2 to lock the flange 3 into the mounting plate 2, thereby strengthening the fixation between the flange 3 and the mounting plate 2 and preventing the flange 3 from detaching from the mounting plate 2. When mounting plate 2 is detached, the side suction port 4 is connected to negative pressure, allowing the dust generated during cutting to pass through the cutting cavity 1 and be absorbed and collected by the side suction port 4. The support plate 6 is fixed to the lower end of the mounting plate 2 to position the mounting plate 2, reducing debugging time. During installation, the flange 3 can be placed on the support plate 6 and then the buckle 5 can be operated to lock it, thereby achieving relative fixation between the cutting cavity 1 and the side suction port 4, facilitating the disassembly and assembly of the side suction port, improving the cleaning efficiency of the dust removal mechanism, and thus improving the production efficiency of the battery cell.

[0013] A magnet (not shown in the figure) is provided on the flange 3. The flange 3 is square in shape. Multiple magnets are arranged in an orderly manner along the edge of the end face of the flange 3, so that the flange 3 can be stably attached to the mounting plate 2 during installation, thereby achieving relative fixation between the cutting cavity 1 and the side dust suction port 4.

[0014] The buckle 5 includes a handle 51, a pull buckle 52, and a locking hook 53. The handle 51 is hinged to the mounting plate 2, the locking hook 53 is fixed to the flange 3, and the pull buckle 52 is rotatably mounted on the handle 51. The pull buckle 52 abuts against the locking hook 53. When locking is required, the handle 51 is rotated to bring the handle 51 closer to the locking hook 53. Then, the pull buckle 52 is rotated to enter the locking hook 53. Finally, the handle 51 is rotated to move the handle 51 away from the locking hook 53, so that the pull buckle 52 applies a pulling force to the locking hook 53 in the direction of the handle 51, thereby fixing the flange 3 and the mounting plate 2.

[0015] The support plate 6 is provided with a slot 61, and the flange 3 is placed in the slot 61 to position the flange 3 and support the flange 3, so as to prevent the flange 3 from slipping due to its own weight and reducing the installation accuracy.

[0016] The embodiments described above are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of this utility model patent application.
