Description

Technical Field

[0001] The utility model belongs to the technical field of battery diaphragms, and in particular relates to a battery diaphragm unwinding device. Background Art

[0002] Lithium battery separator refers to a layer of separator material between the positive and negative electrodes of the battery. It is a very critical part of the battery and has a direct impact on battery safety and cost.

[0003] The prior art discloses a battery diaphragm unwinding device with patent announcement number CN219729944U. The above patent uses a one-way limit between a limit block and a clamping block in an adjustment mechanism. When the tightness of the diaphragm is reduced during coating, the rotating shaft cannot be rotated by the clamping connection, thereby enabling the unwinding wheel to unwind, thereby preventing the diaphragm from loosening and causing a poor coating effect. At the same time, the threaded rod can be adjusted by twisting the threaded rod to adjust its degree so that the distance between the end of the threaded rod and the sleeve can be adjusted, thereby enabling the tightness of the diaphragm during coating to be adjusted, making the device more practical. However, the following deficiencies still exist in actual use: from a practical point of view, the device is inconvenient to operate when installing the diaphragm roll, and it is not easy to install the diaphragm roll, thereby reducing work efficiency. At the same time, diaphragm rolls of various specifications cannot be fixed and installed, resulting in low practicality of the device.

[0004] Therefore, a battery diaphragm unwinding device is needed to solve the problems in the prior art that the diaphragm roll is not easy to install and diaphragm rolls of various specifications cannot be fixed, resulting in low practicality of the device. Utility Model Content

[0024] Further as Figure 3 , Figure 4 and Figure 5As shown, it is worth specifically explaining that the connecting mechanism 4 includes a first connecting rod 402, the first connecting rod 402 is fixedly connected to the rotating device 2 between the support plates 1 through a fixed shaft, the left side of the first connecting rod 402 is rotatably connected to an internally threaded sleeve 403, a first connecting shaft 405 is arranged in the internally threaded sleeve 403, an external thread 406 matching the internally threaded sleeve 403 is arranged on the right side of the outside of the first connecting shaft 405 and connected through threads, a positioning block 404 is fixedly connected to the right side surface of the first connecting shaft 405, and the first connecting shaft 405 is fixedly connected to the right side surface of the first connecting shaft 405. A connecting shaft 405 is fixedly connected to an installation roller 401 on the left side through a limiting mechanism 5, and the installation roller 401 is fixedly connected to a second connecting shaft 4111 on the left side through a limiting mechanism 5. Four clamping blocks 4110 are evenly arranged on the left surface of the second connecting shaft 4111. A limiting shaft 409 is inserted inside the second connecting shaft 4111. A second connecting rod 407 is fixedly connected to the left side of the limiting shaft 409 and is fixedly connected to the rotating device 2 through a fixed shaft. The second connecting rod 407 is provided with a bayonet 408 matching the clamping block 4110.

[0025] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth explaining in detail that a positioning opening matching the positioning block 404 is provided in the first connecting rod 402, an electromagnetic protrusion is provided on the installation roller 401, and the diaphragm roll 6 is installed outside the installation roller 401 by limiting the electromagnetic protrusion.

[0026] According to the above working process, it can be known that: through the setting of the connecting mechanism 4, it is convenient to disassemble the relevant structures when installing the diaphragm roll 6, so that it is convenient to install and fix the diaphragm roll 6 on the installation roller 401, and fix it through the installation roller 401, so that it is convenient to rotate when unwinding, thereby improving work efficiency.

[0027] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth explaining in detail that the limiting mechanism 5 includes two mounting plates 501, and the two mounting plates 501 are respectively fixedly connected to the left side of the first connecting shaft 405 and the right side of the second connecting shaft 4111 and are symmetrically and detachably installed at both ends of the mounting roller 401. Four sliding rods 502 are evenly slidably connected on the mounting plate 501, and one end of the sliding rod 502 close to the mounting roller 401 is fixedly connected to the limiting plate 503, and a spring 504 is sleeved on the outside of the sliding rod 502 between the limiting plate 503 and the mounting plate 501.

At the same time, the mounting roller 401 detachably mounted on the mounting plate 501 is convenient for disassembling the mounting roller 401. By setting the electromagnetic block on the mounting roller 401, the diaphragm roll 6 is limited and fixed when it is sleeved on the mounting roller 401 to prevent it from sliding. The mounting roller 401 is installed on the mounting plate 501, and is fixed to the second connecting rod 407 by the second connecting shaft 4111 cooperating with the clamping block 4110. When the rotating device 2 rotates, the diaphragm roll 6 is driven to rotate on the mounting roller 401, which is convenient for the unwinding operation. At the same time, when the mounting roller 401 is installed, the limiting mechanism 5 pushes the limiting plate 503 so that the diaphragm roll 6 is clamped and limited on the side of the limiting plate 503 with an anti-slip buffer layer through the cooperation of the sliding rod 502 and the spring 504 to prevent it from shifting during rotation.

[0030] In summary: the connection mechanism 4 is provided to facilitate the disassembly of related structures when installing the diaphragm roll 6, so that the diaphragm roll 6 can be installed and fixed on the installation roller 401, and fixed by the installation roller 401, so that it can be rotated when unrolled, thereby improving work efficiency; when the diaphragm roll 6 is installed, the limiting mechanism 5 is provided to fix the two sides thereof to prevent movement during unrolling and causing unrolling errors, and can meet the limit fixation of diaphragm rolls 6 of various specifications, thereby greatly improving the practicability of the device.
