Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery production technology, specifically relating to a twist cap device with a negative pressure collecting terminal cap. Background Technology

[0002] The structure of a lead-acid battery includes a battery case and a battery cover that fit together. The battery case contains electrode groups connected in series, with positive and negative terminals extending outwards. These terminals need to extend beyond the battery cover and connect to terminals. The area on the battery cover where the terminals extend is formed into a terminal groove, and the terminals are sealed using adhesive or other methods.

[0003] Because the battery cover and battery case are sealed with adhesive, and the sealing process requires the battery cover to be inverted with its bottom side facing up, then the sealant is applied to the corresponding groove on the bottom of the battery cover. The battery case, with its internal terminals already assembled, is then placed upside down on the battery cover to complete the seal. Therefore, during manufacturing, the battery cover has a terminal cap at the terminal groove for temporary sealing to prevent sealant leakage when the battery case and cover are closed. When the battery case and cover are closed, the terminal post also extends into this terminal cap, which needs to be removed later to expose the terminal post.

[0004] For example, utility model patent CN222514931U discloses a self-priming cap-twisting device, including a cap-twisting fixture and a pneumatic wrench for driving the fixture to rotate. The fixture includes a sleeve for fitting around the outside of the cap and twisting it off by rotation. The pneumatic wrench is driven by compressed gas. The self-priming cap-twisting device also includes a suction mechanism on the wrench for removing debris generated after the cap is twisted off. The suction mechanism includes: a negative pressure tube, one end of which extends to a position near the root of the cap during use; and a negative pressure generator with a venturi structure, having an air inlet, an air outlet, and an ejector port. The air inlet is connected to an air source, and the ejector port is connected to the other end of the negative pressure tube. In this prior art, a suction mechanism is used to remove debris generated after the cap is twisted off, but the main body of the cap flies out from the discharge port and needs to be collected separately.

[0024] like Figures 1-2 As shown, a twist cap device with a negative pressure collection pole cap includes a twist cap fixture 1 and a pneumatic wrench 2 for driving the twist cap fixture 1 to rotate. The twist cap fixture 1 and the pneumatic wrench 2 are separate designs, but are used together during use.

[0025] The cap-twisting fixture 1 includes a sleeve 11 for fitting onto the outside of the pole cap and twisting off the pole cap by rotation. A discharge cylinder 12 is located above the sleeve 11, and the side wall of the discharge cylinder 12 has discharge holes 121 for discharging the removed pole cap. In the structure shown in the figure, there are two discharge holes 121, arranged opposite each other on the side wall of the discharge cylinder 12. The sleeve 11 has an internal hexagonal through hole 111 that fits into the pole cap. A hexagonal bar 122, shaped like a regular hexagonal prism, is located above the discharge cylinder 12. The hexagonal bar 122 is used to engage with a pneumatic wrench 2 during use.

[0026] The negative pressure cap twisting device also includes a negative pressure collection mechanism mounted on the pneumatic wrench 2 for negative pressure suction to remove the twisted cap. The negative pressure collection mechanism includes a waste hood 3, a negative pressure collection bucket 4, a negative pressure pipe 5, a negative pressure generating element 6, and a fixed bracket 7.

[0027] The waste hood 3 is installed around the outer circumference of the discharge cylinder 12, which has a discharge hole 121.

[0028] The negative pressure collection tank 4 is connected to the waste hood 3 via a connecting channel and is used to temporarily store the collected electrode caps. One end of the top surface of the negative pressure collection tank 4 has an opening for removing the electrode caps collected in the negative pressure collection tank 4, and the opening is provided with an openable and closable cover 41.

[0029] One end of the negative pressure pipe 5 is connected to the negative pressure collection tank 4. A filter plug 51 is provided at the connection between the negative pressure pipe 5 and the negative pressure collection tank 4, and the filter plug 51 has filter holes.

[0030] The negative pressure generator 6 has a venturi structure, which includes an air inlet, an air outlet, and an ejector port. The air inlet is connected to an air source, which is the air discharged through the air outlet 21 of the pneumatic wrench 2. The ejector port is connected to the other end of the negative pressure pipe 5, and the negative pressure pipe 5 is inserted into the ejector port.

[0031] The pneumatic wrench 2 is driven by compressed gas. The side wall of the pneumatic wrench 2 has an air outlet 21 that connects to the internal air chamber of the pneumatic wrench 2. The air outlet 21 includes multiple outlets and is connected to the air inlet.

[0032] The pneumatic wrench 2 has a sealing cover 22 covering the air outlet 21 on its side wall, and an air outlet 221 extending into the air inlet is provided on the sealing cover 22. The sealing cover 22 has a mounting flange 222, and the sealing cover 22 is fixed to the side wall of the pneumatic wrench 2 by screws passing through the mounting flange 222. Modification of the pneumatic wrench 2 is relatively convenient; it only requires opening several air outlets 21 in the side wall and then fixing them with screws. A sealing ring is provided between the mounting flange 222 and the side wall of the pneumatic wrench 2 to ensure airtightness. The sealing cover 22 is integrally formed with the negative pressure generating element 6.

[0033] The fixed bracket 7 is used to fix the negative pressure collection mechanism to the pneumatic wrench 2. One end of the fixed bracket 7 is fixed to the pneumatic wrench 2, and the other end is provided with a bayonet for fixing the negative pressure pipe 5.

[0034] In use, the twist cap tool 1 is installed on the pneumatic wrench 2, and the internal hexagonal through hole 111 is connected to the pole cap. The pneumatic wrench 2 is started to drive the twist cap tool 1 to rotate to remove the pole cap. During the removal of the pole cap, the air outlet 21 on the side wall of the pneumatic wrench 2 emits air towards the sealing cover 22. The air enters the air inlet of the negative pressure generator 6 from the air outlet 221 and is then blown towards the air outlet of the negative pressure generator 6. Due to the venturi structure of the negative pressure generator 6, the airflow will have a suction force on the ejector port as it moves from the air inlet to the air outlet, thereby creating a negative pressure inside the negative pressure tube 5. This also creates a negative pressure inside the negative pressure collection bucket 4 at the bottom of the negative pressure tube 5. Under the action of the negative pressure, the twisted pole cap will be sucked into the negative pressure collection bucket 4 and can be disposed of periodically.
