Description

Technical Field

[0001] This utility model relates to the field of battery insulating ring technology, specifically a battery insulating ring mounting and positioning structure. Background Technology

[0002] Battery insulating rings are insulating components used at the junction of the positive electrode metal cap and the outer casing of cylindrical lithium batteries. Their core function is to isolate the positive electrode metal cap from the battery casing, preventing direct contact between the two and thus avoiding short circuits. They also prevent external impurities from entering the joint gaps, ensuring the safety and stability of the battery. In the production and assembly of cylindrical lithium batteries, the installation of insulating rings is one of the key processes. If insulating rings are missing or improperly installed, it can lead to battery leakage, short circuits, and other malfunctions, which not only affect the battery's lifespan but may also cause safety hazards. Therefore, a special structure is needed to ensure that the insulating rings are accurately installed in the designated positions.

[0003] Traditional cylindrical lithium battery insulation ring installation often employs manual positioning or a single-specification fixed fixture. Manual positioning relies on the operator's experience to determine the insulation ring's placement, which is prone to operational errors, leading to insulation ring misalignment and inaccurate fit between the positive electrode metal cap and the outer casing. On the other hand, a single-specification fixed fixture can only accommodate cylindrical lithium batteries of a specific diameter. When dealing with batteries of different sizes, the entire fixture needs to be replaced, increasing equipment procurement costs and requiring additional time for fixture debugging, resulting in production interruptions and reduced mass production efficiency. To address these issues, we propose a battery insulation ring installation and positioning structure. Utility Model Content

Pulling it can adjust the adjusting rectangular column 3, and resetting it can fix the length. First spring 6: It is sleeved on the end of the limiting member 5 and installed in the limiting storage frame 4. In the natural state, the limiting member 5 is pushed to insert into the limiting hole of the adjusting rectangular column 3. When the limiting member 5 is pulled, it is compressed. After releasing, it helps to reset the limiting position. Rotating component 7: The bottom end is rotatably connected to the inner side of the top of the telescopic support bar 2. A rotating connecting block is provided on one side, which cooperates with the rotating connecting end 16 of the positioning and storage ring 13 to adjust the angle of the positioning and storage ring 13 to ensure alignment with the cylindrical lithium battery 22. Positioning installation ring 8: Located at the top of the positioning storage ring 13, with a ring-shaped telescopic column 10 at the bottom. In conjunction with the telescopic column 10 and the second spring 11, when pressed, the pressure is transmitted to the insulating ring body 12 through the pressure end ring 9. Pressure end ring 9: Located at the bottom of the positioning and mounting ring 8, hollow inside, with the bottom end tightly fitted to the insulating ring body 12. When under pressure, it pushes the insulating ring body 12 from the placement protrusion 15 to the designated connection point of the cylindrical lithium battery 22. Telescopic column 10: It is distributed in a ring at the bottom of the positioning and mounting ring 8. A second spring 11 is provided at the bottom and inserted into the storage tube 14. It retracts when the positioning and mounting ring 8 is pressed, and provides elastic pressure in conjunction with the second spring 11. The second spring 11 is installed at the bottom of the telescopic column 10 and is located inside the storage tube 14. It is compressed when the positioning installation ring 8 is pressed, generating elastic force so that the pressure end ring 9 can stably press the insulating ring body 12, ensuring continuous installation pressure. Insulating ring body 12: placed on the placement protrusion 15 of the positioning and storage ring 13, located between the placement protrusion 15 and the pressure end ring 9, and installed at the junction of the positive electrode metal cap and the outer shell of the cylindrical lithium battery 22 after being pressed, so as to play an insulating role.

Rotary connecting end 16: Located on the outer cylindrical surface of the positioning and storage ring 13, with a rotating shaft at the end, inserted into the rotating connecting block of the rotating component 7, and working with the rotating component 7 to achieve fine-tuning of the angle of the positioning and storage ring 13, ensuring alignment with the cylindrical lithium battery 22; Support guide column 17: Multiple rings are distributed on the other side of the top of the positioning base 1, and an adaptive locking mechanism is provided on the inner side to provide a placement space for the cylindrical lithium battery 22. The locking mechanism is used to achieve battery positioning support. Guide clamping ring 18: Installed inside the support guide column 17, with a slot with a locking post at the bottom end, which engages with the locking block of the locking and fixing ring 20 and is fixed by the locking post, providing an assembly base for the various components of the adaptive locking mechanism; Threaded locking ring 19: It has an internal thread on the inside and is sleeved on the threaded clamping piece 21. It is threadedly engaged with the threaded clamping piece 21. When rotated, it drives the threaded clamping piece 21 to contract or loosen, thereby clamping or disassembling the cylindrical lithium battery 22. Snap-fit ​​fixing ring 20: A snap-fit ​​block is provided on the outer cylindrical surface to snap-fit ​​with the guide clamping ring 18 in the slot, and a threaded clamping piece 21 is provided at the bottom end to connect the threaded clamping piece 21 to the guide clamping ring 18 and provide installation support for the threaded clamping piece 21. Threaded clamping piece 21: Multiple rings are distributed at the bottom of the snap-fit ​​fixing ring 20. The outer side is threaded and the inner wall is provided with rubber protrusions. It contracts in conjunction with the threaded locking ring 19. The rubber protrusions fit the cylindrical lithium battery 22, providing stable clamping and preventing damage. Cylindrical lithium battery 22: For cylindrical lithium batteries, it is placed inside the support guide post 17, directly below the positioning and storage ring 13, and is clamped and fixed by the threaded clamping piece 21. The insulating ring body 12 to be installed at the junction of the positive electrode metal cap and the outer shell is the target component for the installation of the insulating ring.

[0029] Working principle: First, the cylindrical lithium battery 22 is positioned and fixed. The operator places the cylindrical lithium battery 22 inside the multiple annularly distributed support guide posts 17 on the other side of the top of the positioning base 1. At this time, the adaptive locking mechanism starts to work. The guide clamping ring 18 in the adaptive locking mechanism is engaged with the four symmetrically distributed slots at the bottom of the engagement ring 20 and the four symmetrically distributed blocks on the outer cylindrical surface of the engagement ring 20. The clamping posts pass through the blocks to complete the initial fixation. Then, the threaded locking ring 19 is rotated. Its inner thread engages with the outer thread of the multiple annularly distributed threaded clamping pieces 21 at the bottom of the engagement ring 20. As the threaded locking ring 19 is continuously tightened, the threaded clamping pieces 21 gradually retract inward until the inner wall is arc-shaped. The rubber protrusions fit tightly against the cylindrical lithium battery 22, thus achieving stable clamping of cylindrical lithium batteries 22 of different diameters and ensuring that the battery position does not shift during subsequent installation. Next is the length limit adjustment operation of the rectangular column 3. The telescopic support bar 2 on one side of the top of the positioning base 1 has an adjustable rectangular column 3 inserted inside. Before adjustment, the limit component must be operated: the limit storage frame 4 of the limit component is installed inside the front and rear ends of the telescopic support bar 2. The ends of the symmetrically distributed limit pieces 5 inside are fitted with first springs 6. The operator pulls the limit pieces 5 outwards, compressing the first springs 6. At this time, the front end of the limit piece 5 disengages from the equidistant limit holes at the front and rear ends of the adjustable rectangular column 3. Then, according to the height requirements of the cylindrical lithium battery 22, it is pulled up and down for adjustment. Once the rectangular column 3 is positioned appropriately, the limiting piece 5 is released. The first spring 6 resets, pushing the front end of the limiting piece 5 back into the corresponding limiting hole, thus fixing the adjustable telescopic length of the rectangular column 3. The angle and position of the positioning and storage ring 13 are adjusted using a rotating piece 7 mounted on the top of the rectangular column 3. The operator can adjust the overall angle by rotating the rotating piece 7. Simultaneously, the rotating connection end 16 on the outer cylindrical surface of the positioning and storage ring 13 engages with the rotating connection block on one side of the cylindrical surface of the rotating piece 7 via its end rotating shaft, further fine-tuning the angle of the positioning and storage ring 13. Ultimately, the positioning and storage ring 13 is precisely positioned above the cylindrical lithium battery 22, ensuring that the subsequent insulating ring accurately corresponds to the battery installation position, while also ensuring the insulation ring itself... The placement and pre-positioning of the insulating ring body 12: The inner wall of the positioning and storage ring 13 is provided with multiple hemispherical placement protrusions 15. The operator places the insulating ring body 12 on the multiple placement protrusions 15, and uses the placement protrusions 15 to provide initial support and positioning for the insulating ring body 12. At the same time, the six ring-shaped storage cylinders 14 at the top of the positioning and storage ring 13 provide an installation base for the pressure application component, ensuring that the insulating ring body 12 remains stable during the pre-positioning stage and does not shift or fall off. Finally, the pressure application and installation of the insulating ring body 12: At the bottom of the positioning installation ring 8 set at the top of the positioning and storage ring 13, there are six ring-shaped telescopic columns 10. The second spring 11 at the bottom of the telescopic column 10 is located inside the storage cylinder 14, forming a telescopic cooperation structure.The hollow pressure-applying end ring 9 at the bottom of the positioning and mounting ring 8 fits tightly against the insulating ring body 12. The operator presses down on the positioning and mounting ring 8, causing the telescopic column 10 to move downwards within the storage cylinder 14. The second spring 11 compresses, generating continuous pressure. This pressure is transmitted through the pressure-applying end ring 9 to the insulating ring body 12, pushing it downwards from the placement protrusion 15. Finally, it is precisely installed at the junction of the positive electrode metal cap and the outer casing of the cylindrical lithium battery 22, completing the entire insulating ring installation process.
