Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery production, and in particular relates to a self-priming twist cap device. Background Art

[0002] The structure of a lead-acid battery includes a battery slot and a battery cover that cover each other. The battery slot is provided with pole groups. After the pole groups are connected in series, the positive and negative poles are finally extended. The positive and negative poles need to extend out of the battery cover and connect the terminals. The terminal glue groove is formed on the battery cover where the terminal pole extends, and the terminal pole is sealed by means of glue sealing and other means.

[0003] Since glue is used to seal the battery cover and the battery slot, and the battery cover needs to be inverted with the bottom facing up during glue sealing, and then the sealant is added to the corresponding glue groove on the bottom of the battery cover, and then the battery slot with the pole group already assembled inside is placed upside down on the battery cover to complete the seal between the battery slot and the battery cover. Therefore, during production, the battery cover also has a pole cap at the terminal glue groove for temporary sealing to prevent the sealant from leaking out when the battery slot and the battery cover are closed. When the battery slot and the battery cover are closed, the terminal pole also extends into this pole cap, and the pole cap needs to be removed later to leak out the terminal pole.

[0004] For example, the utility model with the authorization announcement number CN215617826U discloses a battery pole cap removal tool, including: a socket sleeve for being sleeved on the outside of the pole cap, the socket sleeve having an inner hexagonal through hole that cooperates with the pole cap; a hexagonal rod with the shape of a regular hexagonal prism, which is used to be plugged into an electric wrench when in use; a discharge barrel, located between the socket sleeve and the hexagonal rod, the inner cavity of the discharge barrel being connected to the inner hexagonal through hole of the socket sleeve, and the side wall of the discharge barrel having a discharge hole for discharging the removed pole cap; the top surface of the discharge barrel is opened, and a mounting piece for mounting the hexagonal rod is provided in the center, and the top of the discharge barrel is located between the inner cavity side wall of the discharge barrel and the mounting piece, and is provided with an impeller blade that can blow air toward one end of the socket barrel during rotation during use.

[0005] However, when the pole cap is removed by the pole cap removal tool, debris may be left at the root of the pole cap. The battery cover is made of plastic and the generated debris will affect the connection terminals at the subsequent end poles, so the debris needs to be removed. Utility Model Content

[0024] The cap-twisting tool 1 includes a sleeve that is used to be sleeved on the outside of the pole cap and twist off the pole cap by rotation when in use, and the sleeve has an inner hexagonal through hole 11 that is sleeved with the pole cap. The top surface of the cap-twisting tool 1 has a hexagonal rod 12 with a regular hexagonal prism shape, and the hexagonal rod 12 is used to be plugged and matched with the pneumatic wrench 2 when in use. The bottom surface of the pneumatic wrench 2 has an inner hexagonal wrench structure that cooperates with the hexagonal rod 12. There is also a discharge barrel 13 between the sleeve and the hexagonal rod 12, and the inner cavity of the discharge barrel 13 is connected to the inner hexagonal through hole 11 of the sleeve, and the side wall of the discharge barrel 13 has a discharge hole 14 for discharging the removed pole cap. In the structure shown in the figure, there are two discharge holes 14, which are relatively arranged on the side wall of the discharge barrel 13.

[0025] The pneumatic wrench 2 is driven by compressed gas. The self-priming cap-twisting device of the utility model also includes a debris suction mechanism provided on the pneumatic wrench 2 for sucking away the debris generated after the pole cap is twisted off, and the debris suction mechanism includes a negative pressure pipe 6 and a negative pressure generating member 7. The pneumatic drive structure of the pneumatic wrench 2 and the structure for driving the cap-twisting tool 1 to rotate in the utility model can adopt the structures commonly used in the prior art, or the existing pneumatic wrench 2 can be directly purchased and then modified to install the debris suction mechanism.

[0026] The side wall of the pneumatic wrench 2 has an air outlet 21 connected to the internal air cavity of the pneumatic wrench 2, and the air outlet 21 includes a plurality of holes. A sealing cover 3 covering the air outlet 21 is provided on the side wall of the pneumatic wrench 2. The sealing cover 3 has a mounting flange 32, and the sealing cover 3 is fixed to the side wall of the pneumatic wrench 2 by screws 4 passing through the mounting flange 32, and a sealing ring 5 is provided between the mounting flange 32 and the side wall of the pneumatic wrench 2. The provision of the sealing ring 5 can ensure the sealing performance. The sealing cover 3 is fixed to the side wall of the pneumatic wrench 2 by screws 4, and the modification of the pneumatic wrench 2 is relatively convenient, and it only needs to open a few air outlets 21 on the side wall and then fix it by screws 4.

[0027] The negative pressure generating member 7 has a Venturi structure, with an air inlet, an air outlet and an injection port, the air inlet is connected to an air source, and in the structure shown in the figure, the air source is the air discharged through the air outlet 21 of the pneumatic wrench 2. The sealing cover 3 is provided with an air outlet nozzle 31 extending into the air inlet of the negative pressure generating member 7, so that the air outlet 21 on the pneumatic wrench 2 is connected to the air inlet of the negative pressure generating member 7 through the sealing cover 3.

[0028] One end of the negative pressure tube 6 extends to a position close to the root of the pole cap when in use, and the injection port of the negative pressure generating part 7 is connected to the other end of the negative pressure tube 6, and the negative pressure tube 6 is plugged and matched with the injection port of the negative pressure generating part 7. The pneumatic wrench 2 is also provided with a fixed bracket 22, and the fixed bracket 22 is provided with a bayonet for fixing the negative pressure tube 6. On the one hand, the negative pressure tube 6 is fixedly installed with the pneumatic wrench 2 by being plugged into the bayonet of the fixed bracket 22, and on the other hand, the negative pressure tube 6 is installed by plugging and matching with the injection port of the pressure generating part 7.

In the process of removing the pole cap, the air outlet 21 on the side wall of the pneumatic wrench 2 discharges air to the side of the sealing cover 3, and the gas enters the air inlet of the negative pressure generating part 7 from the air outlet nozzle 31, and then blows to the air outlet of the negative pressure generating part 7. Due to the Venturi structure of the negative pressure generating part 7, there is a suction force on the injection port during the movement of the air flow from the air inlet to the air outlet, thereby forming a negative pressure inside the negative pressure tube 6. The end of the bottom of the negative pressure tube 6 that extends close to the root of the pole cap can suck away the debris generated after the pole cap is twisted off, and the gas is discharged from the exhaust hole 82, and the debris is collected by the debris collection container 8 and cleaned regularly.
