Description

Technical Field

[0001] The invention relates to the technical field of lithium ion battery processing, in particular to a puncture test device for lithium ion battery processing and a test method thereof. Background Art

[0002] During the processing of lithium-ion batteries, the battery extrusion and acupuncture integrated machine is suitable for simulating the conditions in which various types of batteries are squeezed and punctured during use, transportation and storage. The test should be carried out at an ambient temperature of about 20°C. The battery connected to the thermocouple is placed in a fume hood, and a steel needle with a diameter of 2-8mm is used to pierce the center of the largest surface of the battery at a speed of 10mm / s-40mm / s. The needle is kept for any period of time and the test results are observed. The battery is qualified if it does not explode or catch fire.

[0003] According to announcement number CN115406777A, a puncture test device for lithium-ion battery processing with a protective function is disclosed, including a base, a positioning mechanism, a clamping mechanism, a smoke removal mechanism and a fire extinguishing mechanism. A test box is fixedly installed on the top of the base, a lithium battery is arranged inside the test box, and a partition is fixedly installed on the inner wall of the test box.

[0004] By adopting the above technical scheme, through the coordinated use of the fire extinguishing mechanism and the smoke removal mechanism, when the lithium battery is punctured and catches fire and explodes, it can quickly extinguish the fire and remove the smoke, thereby solving the problem that some existing devices have no protection function during use and cannot extinguish the fire in time when the battery is unqualified and catches fire and explodes, thereby improving the safety of the device and enhancing the practicality of the device. However, the above technical scheme only uses a motor to drive the lithium battery to move to the center position, and cannot accurately determine whether the center of the lithium battery of different sizes corresponds to the center of the steel needle, thereby affecting the accuracy of the experimental data of the puncture test device, and only uses water to extinguish and cool the ignited lithium battery. Since a large amount of water will cause a secondary explosion of the lithium battery, the lithium battery cannot be extinguished first and then cooled, and the toxic smoke generated by the lithium battery cannot be collected and processed, resulting in poor air quality in the experimental site, reducing the working environment quality of the experimenters, endangering the health of the experimenters, and thus reducing the safety of the puncture test device.

[0025] A test method for a puncture test device for lithium-ion battery processing, comprising the following steps:

[0026] S1: When in use, first connect the clamping hydraulic rod to the power supply. When the lithium-ion battery processing puncture test device needs to be used to perform a puncture test on the lithium-ion battery, first use the puncture hole on the test bench to facilitate the puncture test of the lithium-ion battery placed in the middle of the test bench through the steel needle, and extend the steel needle into the puncture hole. By controlling the power supply of the four clamping hydraulic rods, the two first clamping plates and the two second clamping plates can be respectively contacted with and squeezed with the four sides of the lithium-ion battery, and by sliding the sliding push plate inside the mounting groove, When the distances between the outputs of the two sets of clamping hydraulic rods are the same, the center of the lithium-ion battery is located directly below the steel needle. When the lithium-ion battery explodes and catches fire and needs to be cooled down after the fire is extinguished, the wedge-shaped table can be used to conveniently transport the water for cooling the lithium-ion battery to one side, and the filter screen can be used to conveniently filter and isolate the impurities in the water. By manually connecting the output end of the switch valve with the water collection device, the switch valve can be used to conveniently control the switch of the water delivery, so that the water for cooling the battery in the test box can be conveniently transported to the outside for collection and treatment.

[0027] S2: When in use, first connect the industrial air purifier and the solenoid valve to the power supply. When the lithium-ion battery processing puncture test device needs to be used to perform a puncture test on the lithium-ion battery, first use the power delivered by the electric output rod to drive a steel needle with a diameter of 2-8mm to pierce the center of the largest surface of the battery at a speed of 10mm / s-40mm / s, thereby completing a puncture test on the lithium-ion battery. Then, use the installation box and the ventilation fan to accelerate the air flow in the test box, and use the ventilation pipe and the smoke extraction pipe to form air convection, so that the toxic smoke generated by the explosion of the lithium-ion battery in the test box can be quickly circulated and transported to the industrial air purifier for purification. The toxic smoke is further purified through the pipeline connected to the industrial air purifier until it can be discharged into the atmosphere. At the same time, by connecting the input end of the solenoid valve to the external pipeline, it is convenient to manually open the solenoid valve, and the water pipe can be used to transport cooling water to the inside of the test box, and the cooling water can be sprayed by the water spray plate, and multiple spray heads can be used to spray water on the surface of the lithium-ion battery to cool the lithium-ion battery.

[0028] S3: When in use, first connect the electric fire extinguisher nozzle to the power supply. When it is necessary to use the lithium-ion battery processing puncture test device to perform a puncture test on the lithium-ion battery, first use the electric telescopic rod fixed by the two supporting brackets, and use the power output by the electric telescopic rod to drive the pushing block to move left and right. The second reinforcement ring is used to improve the connection stability between the telescopic end of the electric telescopic rod and the pushing block. Since the pushing block is fixed to a mobile placement box on one side, and multiple electric fire extinguisher nozzles are arranged in the mobile placement box, a dry powder fire extinguisher composed of an electric fire extinguisher nozzle and a fire extinguisher tank body is used. The pressurized dry powder in the fire extinguisher tank body is sprayed out by the electric fire extinguisher nozzle, so that the burning lithium-ion battery can be quickly and safely extinguished. The limiting slider slides in the limiting slide groove, so that the multiple dry powder fire extinguishers can be stably moved left and right.

[0029] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0030] First, the present invention is provided with a test positioning mechanism, which can utilize the puncture hole on the test bench to facilitate the puncture test of the lithium-ion battery placed in the middle of the test bench through a steel needle, and the steel needle is extended into the inside of the puncture hole, and by controlling the power supply of the four clamping hydraulic rods, the two first clamping plates and the two second clamping plates can be respectively contacted with and squeezed with the four sides of the lithium-ion battery, and the movement of the two first clamping plates and the two second clamping plates is limited by making the sliding push plate slide inside the installation groove and using the positioning slide bar to slide inside the well-type slide rail, so that the center of the lithium-ion battery is located directly below the steel needle when the distances output by the two groups of clamping hydraulic rods correspond to each other. The steel needle can be used to perform puncture tests on the centers of lithium-ion batteries of different sizes, thereby improving the accuracy of the experimental data of the puncture test device.

[0031] Second, the present invention can protect lithium-ion batteries that explode and burn during puncture tests by providing a toxic gas treatment mechanism and a mobile fire extinguishing mechanism, thereby reducing the danger of the lithium-ion battery to the outside world. The installation box and the ventilation fan can speed up the air flow in the test box, and the ventilation pipe and the smoke pipe form air convection, which can quickly circulate the toxic smoke generated by the explosion of the lithium-ion battery in the test box and transport it to the industrial air purifier for purification. The toxic smoke is further purified through a pipeline connected to the industrial air purifier until it can be discharged into the atmosphere, and then two supports are used to purify the toxic smoke. The electric telescopic rod fixed on the fixed frame can use the power it outputs to drive the pushing block to move left and right. Since the mobile placement box is fixed on one side of the pushing block, and multiple electric fire extinguisher nozzles are arranged in the mobile placement box, a dry powder fire extinguisher composed of an electric fire extinguisher nozzle and a fire extinguisher tank body is used. The pressurized dry powder in the fire extinguisher tank body is sprayed out through the electric fire extinguisher nozzle, which can quickly and safely extinguish the burning lithium-ion battery. The limiting slider slides in the limiting slide groove, so that the multiple dry powder fire extinguishers can be stably moved left and right, which can improve the working environment of the staff and improve the safety of the puncture test device.
