Description

Technical Field

[0001] This utility model relates to the field of lithium battery cell printed termination tape technology, and in particular to a lithium battery cell printed termination tape. Background Technology

[0002] Lithium-ion battery cell printing termination tape is a key auxiliary material in lithium-ion battery production. Made with PET or similar materials and coated with an electrolyte-resistant acrylic adhesive, it adheres firmly to the cell surface. It not only provides reliable insulation protection to prevent short circuits but also marks important information such as cell model, specifications, and production batch through clear, wear-resistant printing, facilitating production management and quality traceability.

[0003] Traditional tape application typically involves two methods: manual application and automated application using tape application equipment. For automated application, the tape roll must first be fitted onto the shaft to ensure a secure installation. This is because the shaft has threaded holes. After fitting the tape roll onto the shaft, tightening the bolts and nuts secures the tape roll, facilitating subsequent use. However, this method of tightening the bolts and nuts with tools is not only cumbersome but also time-consuming and labor-intensive, leading to a significant reduction in production efficiency.

[0004] Therefore, it is necessary to provide a new type of lithium battery cell printing termination tape to solve the above-mentioned technical problems. Utility Model Content

Two threaded discs are threadedly connected to the outside of the bidirectional screw. Four adjusting rods are rotatably connected to the inner walls of the outer, adjacent sides of the two threaded discs. Four connecting blocks are rotatably connected to the distant sides of the multiple adjusting rods. Arc-shaped extrusion blocks are fixedly connected to the distant sides of the multiple connecting blocks. Gaskets are fixedly connected to the distant sides of the multiple arc-shaped extrusion blocks. A guide assembly is installed on the side of the arc-shaped extrusion block closest to the connecting plate.

[0007] Preferably, the connecting assembly includes multiple mounting blocks, with adjacent sides of the multiple mounting blocks being fixedly connected to the outside of the rotating disk, and mounting holes beginning inside the mounting blocks.

[0014] Compared with related technologies, the lithium battery cell printing termination tape provided by this utility model has the following advantages:

[0015] Beneficial effects:

[0016] This invention utilizes a motor-driven bidirectional screw to move components such as a threaded disc, adjusting rod, connecting block, and arc-shaped extrusion block, enabling rapid installation and fixing of the tape roll. This avoids the time-consuming and laborious process of manually tightening bolts and nuts with tools, effectively improving production efficiency.

[0023] 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.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 A lithium battery cell printed termination tape is disclosed. The tape comprises a support ring 1, which serves as the internal load-bearing structure of the tape body 2, providing a stable support foundation for the tape and ensuring its shape stability during winding and unwinding. This allows the tape body 2 to be tightly wound around the support ring 1, ensuring the tape does not become loose or deformed during use. One side of the support ring 1 contacts a connecting plate 3, which plays a crucial role in connection and transition. A rotating disk 4 is fixedly connected to one side of the connecting plate 3, allowing the connected components to operate flexibly, facilitating subsequent installation and use of the tape.

[0026] The connecting assembly includes multiple mounting blocks 5, one side of which is fixed to the connecting plate 3, and the other side is tightly connected to the rotating disk 4, thus firmly combining the connecting plate 3 and the rotating disk 4 together. Mounting holes 6 are provided inside the mounting blocks 5 for use with bolts. During installation, the tight fit between the bolts and the mounting holes 6 ensures a secure and reliable connection between the connecting plate 3 and the rotating disk 4, preventing loosening or displacement during equipment operation and ensuring the stability of the entire structure.

[0027] The motor 7, fixedly connected to the inside of the rotating disk 4 near the connecting plate 3, is the power source for the entire device. The drive end of the motor 7 is fixedly connected to one end of the bidirectional screw 8. When the motor 7 starts running, it efficiently drives the bidirectional screw 8 to rotate. A limiting disk 16, fixedly connected to the end of the bidirectional screw 8 away from the motor 7, plays a crucial limiting role, preventing the threaded disk 9 near the limiting disk 16 from falling off during the rotation of the bidirectional screw 8, thus ensuring the safety and stability of the entire transmission structure. Two threaded disks 9 are connected to the external threads of the bidirectional screw 8. As the bidirectional screw 8 rotates, the two threaded disks 9 move precisely to both sides according to the thread direction of the bidirectional screw 8. Four adjusting rods 10 are rotatably connected to the inner wall of the outer side of the threaded disk 9. When the threaded disk 9 moves, the adjusting rods 10 move accordingly, thereby driving the connecting block 11 rotatably connected to it to move. The movement of the connecting block 11 causes the arc-shaped extrusion block 12 fixedly connected to it to move as well. During the movement of the multiple arc-shaped extrusion blocks 12, the gaskets 13 fixedly connected to the opposite side are made of rubber and have good flexibility and friction. Under the drive of the arc-shaped extrusion block 12, they can tightly press against the inside of the support ring 1, thereby achieving a firm fixation of the support ring 1 and the tape body 2, ensuring that the tape can be stably unwound in subsequent use without shaking or falling off.

[0028] The guide assembly, installed on the side of the arc-shaped extrusion block 12 near the connecting plate 3, further enhances the stability of the structural movement. One end of the guide rod 14 in the guide assembly is fixedly connected to the inner wall of the arc-shaped extrusion block 12 near the connecting plate 3, and the other end is slidably connected within multiple guide holes 15 opened on the side of the connecting plate 3 away from the rotating disk 4. During the movement of the arc-shaped extrusion block 12, the guide rod 14 slides along the inner wall of the guide holes 15, providing precise guidance for the movement of the arc-shaped extrusion block 12, ensuring that the arc-shaped extrusion block 12 remains stable during movement without deviation or shaking, thereby ensuring that the entire device can stably complete the installation and fixing operation of the tape.

[0029] The working principle of the lithium battery cell printing termination tape provided by this utility model is as follows:

[0030] During installation, first, connect the connecting plate 3 to the rotating disk 4, ensuring tight contact. Then, using bolts and mounting holes 6 on the mounting block 5, assemble the connecting plate 3 and the rotating disk 4 into one unit. Next, install the tape body 2. Start the motor 7, which releases power to drive the bidirectional screw 8. The bidirectional screw 8 drives the limiting disc 16 to rotate smoothly on one side of the connecting plate 3. The limiting disc 16 plays a crucial limiting role, effectively preventing the threaded disc 9 near it from accidentally falling off during movement. As the bidirectional screw 8 continues to rotate, the two threaded discs 9 move uniformly to both sides according to the screw's thread guide. The movement of the threaded discs 9 causes the connected adjusting rod 10 to move synchronously, thereby driving the connecting block 11 to follow the displacement. The movement of the connecting block 11 causes multiple arc-shaped extrusion blocks 12 to move synchronously, causing the gasket 13 to gradually converge. During this process, the movement of the arc-shaped extrusion blocks 12 also allows the guide rod 14 to slide smoothly on the inner wall of the guide hole 15, providing stable support for the overall movement. After the multiple arc-shaped extrusion blocks 12 are gathered in place, the support ring 1 inside the tape body 2 is accurately placed outside the multiple arc-shaped extrusion blocks 12. Then, the motor 7 is started in reverse, causing the bidirectional screw 8 to rotate in the opposite direction. The two threaded discs 9 move towards each other, driving the adjusting rod 10 to move in the opposite direction, and the connecting block 11 also moves closer. This causes the multiple arc-shaped extrusion blocks 12 to cause the gasket 13 to expand outward, tightly pressing against the inner wall of the support ring 1 inside the tape body 2, successfully achieving a firm fixation of the tape roll. This effectively ensures that the tape can be stably unwound during subsequent equipment operation, without shaking or falling off.
