Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid battery detection, and in particular relates to a lead-acid battery sealing detection device. Background Art

[0002] Lead-acid batteries usually have two shapes: cylindrical and square. The inside of the lead-acid battery adopts a spiral winding structure, and a very fine and highly permeable polyethylene film isolation material is used to separate the positive and negative electrodes. The lead-acid battery is filled with an organic electrolyte solution. If the top shell of the lead-acid battery is not well sealed during welding, dust and liquid will penetrate, which may cause the battery box to break and the electric vehicle cannot be driven. In severe cases, the battery box will short-circuit, bringing huge safety risks to the electric vehicle.

[0003] For this reason, the sealing of the lead-acid battery housing must be ensured, and the sealing of the lead-acid battery housing must be tested when producing lead-acid batteries.

[0004] The Chinese utility model patent with publication number CN212693156U discloses an air tightness detection device for battery processing, including a base, a bracket fixedly connected to the top of the base, a top plate fixedly connected to one side of the bracket, a cylinder fixedly connected to the bottom of the top plate, a piston rod of the cylinder fixedly connected to an air bin, an air nozzle is provided at the bottom of the air bin, and an air pump is fixedly connected to the bottom of the top plate.

[0005] This device drives the lead-acid battery into the water tank through a cylinder, and determines the sealing of the lead-acid battery by observing whether bubbles are generated in the water tank. When the lead-acid battery enters the water tank, due to its large volume, it will produce large ripples on the water surface, affecting the observation of bubbles. Summary of the invention

[0006] The object of the present invention is to provide a lead-acid battery sealing detection device to solve at least one of the above-mentioned technical problems.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A lead-acid battery sealing detection device, comprising:

[0009] pool;

[0010] A mounting plate disposed above the pool;

[0011] A lifting mechanism installed between the mounting plate and the water pool, used to drive the lead-acid battery in and out of the water pool;

[0012] A charging assembly, used for charging the lead-acid battery;

[0013] A transparent lid bowl, used to cover the upper part of the lead-acid battery and collect gas leaked from the lead-acid battery;

[0014] The assembly line comprises a first section and a second section, wherein the first section and the second section are respectively arranged on opposite sides of the lifting mechanism and are used for transporting the lead-acid batteries.

[0015] The present invention uses a water pool to hold water, a mounting plate to install a lifting mechanism, a lifting mechanism to drive the lead-acid battery in and out of the water in the pool, and an inflation assembly to inflate and pressurize the lead-acid battery. After the lead-acid battery enters the water, if the sealing performance of the top cover of the lead-acid battery is not good, bubbles will emerge from the top cover. The transparent cover bowl is used to collect the bubbles. After the lead-acid battery is put into the water, the transparent cover bowl is covered. There is no need to wait for the water surface to become calm, and the lead-acid battery can be directly inflated. The gas escaping from the top of the lead-acid battery will be collected on the top of the transparent cover bowl for easy observation.

[0020] Furthermore, the transparent covered bowl is provided with a plurality of exhaust holes around the inflation head, and a sealing assembly is provided at the exhaust holes, through which the gas inside the transparent covered bowl is exhausted. The transparent covered bowl can be placed on the lead-acid battery first, and then the lead-acid battery and the transparent covered bowl are slowly put into water, so that the inside of the transparent covered bowl can be filled with water, which is convenient for collecting bubbles that emerge later. After the transparent covered bowl is filled with water, the exhaust holes can be sealed through the sealing assembly to prevent the subsequently collected gas from being discharged from the exhaust holes.

[0021] Further, the sealing assembly includes a sealing ring, a pull rod, a pull ring and a rubber sleeve corresponding to the exhaust holes one by one, the sealing ring is sleeved on the inflation head and located in the transparent cover bowl, the pull rod passes through the exhaust hole corresponding to it, and its bottom is fixed to the top surface of the sealing ring, and its top is fixed to the pull ring, the rubber sleeve is sleeved on the lower part of the pull rod and sealed and fixed to the sealing ring, the size of the sealing ring is adapted to the inflation head, and the size of the rubber sleeve is also adapted to the exhaust hole, the set pull rod is used to connect the pull ring and the sealing ring, and is also used to install the rubber sleeve, the set pull ring is used to drive the rubber sleeve and the sealing ring to approach or move away from the transparent cover bowl, the set rubber sleeve is used to block the exhaust hole, and the set sealing ring is used to further seal the exhaust hole from the inside of the transparent cover bowl; pulling the pull ring can drive the rubber sleeve and the sealing ring to approach the transparent cover bowl, the rubber sleeve is plugged into the exhaust hole to block the exhaust hole, the surface of the sealing ring close to the transparent cover bowl is a surface, it fits the transparent cover bowl to seal the exhaust hole, and the rubber sleeve is in close contact with the exhaust hole, and the rubber sleeve can achieve a good sealing effect.

[0022] Furthermore, a rubber layer is provided on the surface of the sealing ring close to the transparent lid bowl, and the rubber layer is integrally formed with the rubber sleeve. The sealing effect of the sealing ring can be enhanced by the provided rubber layer.

[0023] Furthermore, a limiting portion is provided at the bottom of the transparent bowl for positioning the transparent bowl and the lead-acid battery.

[0024] Furthermore, the storage platform includes a square frame and a plurality of unpowered rollers installed in the square frame, which facilitates the movement of the lead-acid battery on the storage platform and is conducive to the simultaneous detection of multiple lead-acid batteries.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention uses a water pool to hold water, a mounting plate to install a lifting mechanism, and a lifting mechanism to drive the lead-acid battery in and out of the water in the pool.
