Description

Technical Field

[0001] The present invention relates to the technical field of battery detection, and in particular to a battery explosion-proof intelligent detection device with a fixed-point detection function. Background Art

[0002] Lithium batteries are a common type of battery. Multiple lithium battery cells are typically combined in a specific configuration and connection to form a battery system, known as a lithium battery pack. These are widely used in portable electronic devices, power tools, electric vehicles, and energy storage systems. Lithium battery packs are favored for their lightweight, large capacity, and high energy density. To ensure their safety, they require mechanical explosion-proof performance testing. These tests primarily include: impact testing, which simulates a short circuit caused by an accidental impact or collision; extrusion testing, which simulates damage caused by being squeezed by a hard object or subjected to external forces; and vibration testing, which simulates damage caused by vibration during transportation or use. Existing equipment typically first inspects lithium battery packs for visible physical damage, breakage, deformation, or cracks. The intact lithium battery pack is then secured to an impact test bench. The impact test equipment is then activated, subjecting the pack to an impact test. The post-impact test is then observed and recorded.

[0003] However, the existing battery explosion-proof detection device does not have a fixed-point detection function when performing explosion-proof detection on batteries. This makes it inconvenient to perform fixed-point detection on battery locations that are easily bumped, thereby affecting the accuracy of battery explosion-proof detection. Summary of the Invention

[0004] The object of the present invention is to provide a battery explosion-proof intelligent detection device with a fixed-point detection function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the battery explosion-proof intelligent detection device with a fixed-point detection function includes an explosion-proof cabinet, a support table is installed on the cabinet table of the explosion-proof cabinet, and a feed port is opened on one side of the explosion-proof cabinet, two electric telescopic rods are symmetrically installed on the side of the interior of the explosion-proof cabinet away from the feed port, a sealing plate is installed on the telescopic end of the two electric telescopic rods, a linkage rod is installed on the side of the sealing plate close to the electric telescopic rod, a loading plate is installed on the linkage rod, two transverse guide rails are symmetrically installed on the top of the explosion-proof cabinet, a first slide is slidably installed on the two transverse guide rails, the two first slides are connected by a longitudinal guide rail, a second slide is slidably installed on the longitudinal guide rail, and a hydraulic A lifting rod, a clamping head is installed at the end of the hydraulic lifting rod, and a striker is clamped on the clamping head. A positioning scanner is installed in the explosion-proof cabinet. When the battery needs to be tested for explosion-proof, the battery to be tested is clamped on the loading plate. Starting the electric telescopic rod can control the loading plate to move to the support platform in the explosion-proof cabinet, and realize the sealing of the feed port by the sealing plate. At the same time, the battery position is scanned and positioned by the positioning scanner. The operation of the horizontal guide rail and the longitudinal guide rail can be controlled accordingly according to the test point requirements of the battery specifications. The hydraulic lifting rod can be driven by the first slide and the second slide to move to any position on the plane, so as to facilitate rapid positioning according to the test point, and the battery can be subjected to fixed-point impact detection by driving the striker by starting the hydraulic lifting rod.

[0006] Furthermore, a protective cover is installed on one side of the interior of the explosion-proof cabinet, and the positioning scanner is located inside the protective cover. The protective cover can protect the positioning scanner. Tempered glass is provided on one side of the explosion-proof cabinet, which facilitates observation by inspection personnel.

[0007] Furthermore, a plurality of air holes are provided on the top of the explosion-proof cabinet, and a cover is installed on the top of the explosion-proof cabinet, an opening is provided on the top of the cover, an air collecting hood is installed on the opening, an air pump and a purifier are installed on one side of the explosion-proof cabinet, the input end of the air pump is connected to the air collecting hood through an air suction pipe, and the output end of the air pump is connected to the input end of the purifier through an air supply pipe. When the battery has thermal runaway and spontaneous combustion during the impact test, harmful exhaust gas will be generated. At this time, starting the air pump can perform negative pressure suction on the air holes through the air suction pipe, the air collecting hood and the cover, which is conducive to sucking the harmful exhaust gas in the explosion-proof cabinet and transporting it to the purifier through the air supply pipe for purification, thereby avoiding pollution of the detection environment.

[0008] Furthermore, the cover shell is provided with a sliding groove symmetrically at the front and back, and two sliders are slidably installed in the sliding groove, and a connecting block is installed on the two sliders, and a baffle is installed on the connecting block, and the lower surface of the baffle is in contact with the top of the explosion-proof cabinet, and a plurality of regulating ports are provided on the baffle, and the plurality of regulating ports correspond to a plurality of air holes one by one, and a transmission rod is installed on one side of the baffle, and a sliding hole is provided on the side of the cover shell close to the transmission rod, and the transmission rod passes through the sliding hole and is slidably matched, and a connecting plate is installed on the end of the transmission rod away from the baffle, and a magnetic block is installed on the side of the connecting plate close to the transmission rod, a power supply is installed on the cover shell, a thermistor is installed in the gas collecting hood, and an electromagnet is installed on the side of the cover shell close to the sliding hole.

When the magnetic force of the electromagnet decreases, since the slider can move in the slide groove, the connecting plate can drive the baffle to move synchronously through the transmission rod during the movement, which is convenient for controlling the overlapping area of ​​the control port and the air hole, so that the overlapping area of ​​the control port and the air hole can be gradually increased according to the increase of heat, thereby increasing the air intake of the air hole, which is beneficial to improving the absorption efficiency of the harmful exhaust gas in the explosion-proof cabinet.

[0009] Furthermore, the regulating port is composed of a combination of a rectangular hole and a trapezoidal hole, and the rectangular hole is consistent in size with the air hole, which is beneficial for gradually increasing the overlap between the regulating port and the air hole as the baffle moves.

[0010] Furthermore, the resistance of the thermistor increases as the heat increases, and the electromagnet and the magnetic block are magnets with the same polarity.

[0011] Furthermore, the connecting plate and the cover are connected by an elastic band. The elastic force of the elastic band is conducive to quickly controlling the connecting plate to move toward the electromagnet when the magnetic force of the electromagnet changes.

[0012] Furthermore, a fixed rod is installed in the opening, a fixed sleeve is installed on the fixed rod, a rotating shaft is rotatably installed in the fixed sleeve, a plurality of blades are installed on the circumferential side wall of the rotating shaft, a speed sensor is installed on the upper end of the rotating shaft, a driving guide rail is installed on the inner side of the explosion-proof cabinet close to the protective cover, a movable seat is slidably installed on the driving guide rail, a linkage plate is installed on the movable seat, a wiper is installed on the linkage plate, the wiper is in contact with the protective cover, and the speed sensor is electrically connected to the driving guide rail. When the intake air volume changes, the driving force of the airflow on the blades can drive the blades to rotate, so that the rotating shaft can rotate accordingly with the change of the intake air volume. At the same time, the speed sensor detects the speed of the rotating shaft, and the speed sensor can control the movement rate of the movable seat on the driving guide rail to increase, so that the movement rate of the movable seat can be automatically adjusted according to the change of the intake air volume, which is beneficial for the movable seat to drive the wiper to clean the protective cover through the linkage plate during movement, and can prevent smoke from adhering to the protective cover and affecting the positioning accuracy of the positioning scanner.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present application uses a positioning scanner to scan and locate the battery position, and can control the operation of the transverse guide rail and the longitudinal guide rail accordingly according to the inspection point requirements of the battery specifications. It can drive the hydraulic lifting rod to move to any position on the plane through the first slide and the second slide, so as to facilitate rapid positioning according to the inspection point, and can start the hydraulic lifting rod to drive the impact pin to perform fixed-point impact detection on the battery.

[0014] In the present application, when thermal runaway and spontaneous combustion occur during the battery impact test, the vacuum pump is started, and negative pressure suction can be performed on the air holes through the suction pipe, the air collecting hood and the cover, which is conducive to sucking out the harmful exhaust gas in the explosion-proof cabinet and transporting it to the purifier through the air pipe for purification, thereby avoiding pollution of the testing environment.

[0015] The present application uses a thermistor to increase the corresponding resistance value according to the change of heat, so that the distance between the electromagnet and the magnetic block can be automatically adjusted according to the change of gas heat, which is convenient for controlling the overlapping area of ​​the control port and the air hole, thereby increasing the air intake of the air hole, which is beneficial to improving the absorption efficiency of harmful exhaust gas in the explosion-proof cabinet.

[0016] In this application, as the air intake volume changes, the speed of the rotating shaft can be detected by a speed sensor, and the speed sensor can control the increase in the moving speed of the moving seat on the drive guide rail, so that the moving speed of the moving seat can be automatically adjusted according to the change in the air intake volume, which is beneficial for the moving seat to drive the wiping plate to clean the protective cover through the linkage plate during the movement.

The input end of 07 is connected through the gas pipe 1808. When the battery experiences thermal runaway and spontaneous combustion during the impact test, harmful exhaust gas will be generated. At this time, the vacuum pump 1805 is started, and the air hole 1801 can be sucked under negative pressure through the suction pipe 1806, the gas collecting hood 1804 and the cover 1802, which is conducive to sucking the harmful exhaust gas in the explosion-proof cabinet 1 and transporting it to the purifier 1807 for purification through the gas pipe 1808, so as to avoid pollution of the detection environment.

[0023] The cover 1802 is provided with a slidable groove 1902 symmetrically in front and back, and two sliders 1903 are slidably installed in the slid groove 1902.

When harmful exhaust gas with heat enters the gas collecting cover 1804, the thermistor 1901 increases according to the heat resistance value, which can control the current intensity entering the electromagnet 1912 and the magnetic strength of the electromagnet 1912 accordingly. Therefore, the distance between the electromagnet 1912 and the magnetic block 1910 can be automatically adjusted according to the change of gas heat.

[0024] The regulating port 1906 is composed of a combination of a rectangular hole and a trapezoidal hole, and the rectangular hole is consistent in size with the air hole 1801, which is conducive to gradually increasing the overlap between the regulating port 1906 and the air hole 1801 as the baffle 1905 moves.

[0025] The resistance of the thermistor 1901 increases as the heat increases, and the electromagnet 1912 and the magnetic block 1910 are magnets with the same polarity.

[0028] Working principle of the present invention: When it is necessary to perform explosion-proof testing on the battery, the battery to be tested is clamped on the loading plate 7. The electric telescopic rod 4 is started to control the loading plate 7 to move to the support platform 2 in the explosion-proof cabinet 1, and the sealing plate 5 is used to seal the feed port 3. At the same time, the battery position is scanned and positioned by the positioning scanner 15. The operation of the transverse guide rail 8 and the longitudinal guide rail 10 can be controlled accordingly according to the inspection point requirements of the battery specifications. The hydraulic lifting rod 12 can be driven by the first slide 9 and the second slide 11 to move to any position on the plane, so as to facilitate rapid positioning according to the inspection point. In addition, the battery can be subjected to fixed-point impact testing by driving the striker 14 by starting the hydraulic lifting rod 12.

[0029] When the battery experiences thermal runaway and spontaneous combustion during the impact test, harmful exhaust gas will be generated. At this time, the vacuum pump 1805 is started, and negative pressure suction can be performed on the air hole 1801 through the suction pipe 1806, the gas collecting hood 1804 and the cover 1802, which is conducive to sucking out the harmful exhaust gas in the explosion-proof cabinet 1 and transporting it to the purifier 1807 through the air supply pipe 1808 for purification, thereby avoiding pollution of the detection environment.

[0030] When harmful exhaust gas with heat enters the gas collecting cover 1804, the thermistor 1901 increases according to the heat resistance value, which can control the current intensity entering the electromagnet 1912 and the magnetic strength of the electromagnet 1912. As a result, the distance between the electromagnet 1912 and the magnetic block 1910 can be automatically adjusted according to the change of gas heat. When the magnetic force of the electromagnet 1912 decreases, the elastic force of the elastic band 1911 is conducive to quickly controlling the connection plate 1900 when the magnetic force of the electromagnet 1912 changes. 9 moves toward the electromagnet 1912. Since the slider 1903 can move in the slide groove 1902, the connecting plate 1909 can drive the baffle 1905 to move synchronously through the transmission rod 1907 during the movement, which is convenient for controlling the overlapping area of ​​the control port 1906 and the air hole 1801. The overlapping area of ​​the control port 1906 and the air hole 1801 can be gradually increased according to the increase of heat, thereby increasing the air intake of the air hole 1801, which is beneficial to improving the absorption efficiency of the harmful exhaust gas in the explosion-proof cabinet 1.

[0031] When the air intake volume changes, the airflow pushes the blades 2004, which can drive the shaft 2003 to rotate, so that the shaft 2003 can rotate accordingly with the change of the air intake volume. At the same time, the speed sensor 2005 detects the speed of the shaft 2003, and the speed sensor 2005 can control the movement speed of the moving seat 2007 on the guide rail 2006 to increase the movement speed, so that the movement speed of the moving seat 2007 can be automatically adjusted according to the change of the air intake volume, which is beneficial for the moving seat 2007 to drive the wiping plate 2009 to clean and wipe the protective cover 16 through the linkage plate 2008 during the movement, so as to avoid the smoke adhering to the protective cover 16 and affecting the positioning accuracy of the positioning scanner 15.
