[0001] This utility model belongs to the field of battery technology, specifically relating to a sealing tooling for processing cylindrical batteries. Background Art

[0002] Currently, the sealing equipment used in the production process of cylindrical steel-cased batteries allows the battery sealing process to be carried out under dry gas at normal atmospheric pressure (standard atmospheric pressure). A search reveals that application number "CN201620859441.1" discloses "a cylindrical lithium-ion battery sealing device," which describes that "this utility model includes a steel casing and a positioning fixture for sealing the steel casing. The sealing device also includes a negative pressure cavity sealed to the top of the positioning fixture, and a sealing mold penetrating the negative pressure cavity. The sealing mold is slidably disposed with the negative pressure cavity. With this structural design, a negative pressure can be formed inside the steel casing that cooperates with the negative pressure cavity. Under this state, the steel casing is then sealed by the sealing mold." The sealing device utilizes the positioning fixture for sealing the steel casing, and includes a negative pressure cavity sealed to the top of the positioning fixture, and a sealing mold penetrating the negative pressure cavity, with the sealing mold slidably disposed with the negative pressure cavity. With this structural design, the negative pressure cavity can be set up to form a negative pressure inside the steel shell that matches the negative pressure cavity. In this state, the steel shell is sealed by the sealing mold. However, the following problems still exist in actual use:

[0003] In actual use, it is impossible to test the airtightness after sealing, which leads to the need for subsequent testing and wastes a lot of time.

[0004] Therefore, providing a tooling that can perform airtightness testing on batteries is highly practical. Utility Model Content

[0005] The purpose of this invention is to provide a sealing fixture for processing cylindrical batteries, thereby solving the aforementioned technical problems.

[0006] This utility model provides a sealing fixture for cylindrical battery processing, including a base and a leakage detection component.

[0007] Wherein, two support plates are provided on the top of the base, a plurality of support rods are provided on the top of the two support plates, and a connecting plate is provided on the top of the plurality of support rods;

[0008] The air leakage detection component includes an electric cylinder mounted on the top of a connecting plate. The output shaft of the electric cylinder passes through the connecting plate and is connected to an upper mold. A vent hole is provided at the bottom of the upper mold. A conveying pipe is sealed and connected to one side of the upper mold. A speedometer is sealed and connected to the end of the conveying pipe. Fixing brackets are provided on both sides of the speedometer. The ends of the two fixing brackets are fixedly connected to one of the support rods. Two fixing plates are provided at the bottom of the base. A reinforcing plate is provided between the two fixing plates. An air pump is provided on the top of the reinforcing plate. A connecting pipe is sealed and connected to the top of the air pump. The top of the connecting pipe passes through the base and is sealed and connected to a lower mold.

[0009] In this embodiment, an air pump is provided to facilitate the user placing the battery into the lower mold. The first and second protective shells then secure the battery. The PLC controller activates the electric cylinder, which drives the upper mold to press down on the battery, thus sealing it. After sealing, the user activates the air pump via the PLC controller, generating gas that is then sent into the lower mold through a connecting pipe. If leakage occurs, the gas will pass through the battery, through the vent and air hole, into the upper mold, and then be transported to the speedometer via a delivery pipe. The speedometer will then display the pressure, indicating whether the battery is properly sealed. If it is sealed, the speedometer will remain unchanged; if there is a leak, the speedometer will change, thus enabling the detection of battery airtightness.

[0010] In one embodiment of this utility model, the top of the lower mold is provided with an air vent, and the outer wall of the lower mold is provided with a plurality of reinforcing rods.

[0011] In this embodiment, the reinforcing rod facilitates the support and fixation of the lower mold, making the lower mold more stable during use and preventing it from shaking.

[0012] In one embodiment of this utility model, the bottoms of several reinforcing rods are fixedly connected to the base, and a first protective shell is provided on the top of the lower mold.

[0013] In this embodiment, the first protective shell facilitates cooperation with the second protective shell to fix the battery in place, making the battery more stable and preventing it from shaking when it is sealed later.

[0014] In one embodiment of this utility model, a movable component is further included. The movable component includes two sliding guide rails disposed on the top of the base. Sliders are slidably connected inside the two sliding guide rails. Support bars are provided on the top of the two sliders. A second protective shell is provided between the two support bars.

[0015] In this embodiment, the slider allows it to slide within the sliding guide rail, thereby moving the support bar and causing the second protective shell to continuously approach the first protective shell.

[0016] In one embodiment of this utility model, one end of the base is provided with two load-bearing plates, and an electric telescopic rod is provided inside the two load-bearing plates. A connecting frame is provided on one side of the electric telescopic rod, and the end of the connecting frame is fixedly connected to the support bar. The other end of the base is provided with the same structure as one end.

[0017] In this embodiment, the electric telescopic rod allows the user to easily open it via a PLC controller, causing the electric telescopic rod to move the connecting frame, which in turn drives the support bar to move, so as to cooperate with the slider and bring the second protective shell closer to the first protective shell.

[0018] In one embodiment of this utility model, the base is made of chromium metal, and a PLC controller is provided at one end of the other support rod.

[0019] In this embodiment, the presence of chromium metal facilitates more stable support for other parts when using the base, and ensures that the base itself remains intact for a long time, thus improving stability during use.

[0020] In one embodiment of this utility model, the electric cylinder, the air pump, and the electric telescopic rod are all electrically connected to the PLC controller, and the PLC controller is electrically connected to an external power supply.

[0021] In this embodiment, the provided PLC controller facilitates the power supply control of electrical equipment, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when required.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The user turns on the air pump via the PLC controller, causing the pump to generate gas that is sent into the lower mold through the connecting pipe. If there is a leak, the gas will pass through the battery, through the air outlet and vent, into the upper mold, and then be transported to the speedometer through the delivery pipe. The speedometer will then display the pressure, thus determining whether the battery is properly sealed. If it is normal, the speedometer will remain unchanged; if there is a leak, the speedometer will change, thereby enabling the detection of the battery's airtightness. Attached Figure Description

[0044] See also Figure 1 The base 100 is made of metal chromium, and a PLC controller is provided at one end of another support rod 120 .

[0045] In one specific embodiment, the presence of chromium metal facilitates more stable support for other parts when using the base 100, and ensures that the base itself remains intact for a long time, thus improving stability during use.

[0046] See also Figure 1-4 The electric cylinder 210, the air pump 280 and the electric telescopic rod 700 are all electrically connected to the PLC controller, and the PLC controller is electrically connected to the external power supply.

[0047] In one specific embodiment, a PLC controller is provided to facilitate power control of electrical equipment, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0048] In use, the user first places the battery into the lower mold 2910. The electric telescopic rod 700 is then activated via a PLC controller, causing the connecting frame 800 to move. The connecting frame 800 then drives the support bar 530 to move, engaging with the slider 520 to bring the second protective shell 540 close to the first protective shell 400.

The battery is pressed down to seal it. After sealing, the user turns on the air pump 280 via the PLC controller. The air pump 280 generates gas, which is then sent into the lower mold 2910 through the connecting pipe 290. If there is a leak, the gas will pass through the battery, through the air outlet and vent, into the upper mold 220, and then through the delivery pipe 230 to the speedometer 240. The speedometer 240 will then display the pressure, thus determining whether the battery is properly sealed. If it is sealed, the speedometer 240 will remain unchanged; if there is a leak, the speedometer 240 will change, thereby detecting the airtightness of the battery.
