Description

Technical Field

[0002] Lithium-ion batteries require a short-circuit test after the battery packaging operation is completed. The battery short-circuit test is an experimental method for evaluating the safety and performance of the battery. That is, an insulation resistance tester is used to test the insulation between the positive and negative poles and the shell, so as to ensure the safety of the battery.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The existing battery short-circuit tester cannot form a closed loop when testing batteries that have failed to be filled during preparation. At this time, the batteries that have failed to be filled can be screened out, but when such batteries are short-circuited, they are very likely to expand and catch fire, and then explode. They need to be quickly screened out to prevent the expanded and flammable batteries from damaging the entire test line, thereby reducing the battery test rate and making it impossible to maintain the rapid progress of the battery short-circuit test.

[0032] Embodiment 1: A battery short circuit rapid testing machine, such as Figure 1-Figure 4As shown, it includes a conveying device 1, which is a belt conveyor, and the batteries are evenly arranged on the conveying device. The left side of the conveying device 1 is fixedly connected to a control terminal, and the middle part of the conveying device 1 is fixedly connected to a fixed frame 2 located above it, and the upper part of the fixed frame 2 is fixedly connected to a control device 3 electrically connected to the control terminal. The control device 3 is an existing three-axis manipulator, and the top of the control device 3 is fixedly connected to a short-circuit tester 4 electrically connected to the control terminal. The control device 3 is provided with two docking frames 5 distributed in a mirror image, and the control device 3 can control the two docking frames 5 to move up and down, left and right, and front and back. The docking frame 5 is fixedly connected to a docking plate 6 electrically connected to the short-circuit tester 4, and the docking plate 6 is used to dock with the two poles of the battery. The front side of the conveying device 1 is fixedly connected to a first push rod 7 electrically connected to the control terminal, and the front side of the conveying device 1 is fixedly connected to a sliding frame 8. A box for collecting batteries is placed below the sliding frame 8 (not shown in the figure), and a suction cup 9 is fixedly connected to the telescopic end of the first push rod 7. The disk 9 is connected to the external negative pressure device and is used to absorb batteries. The rear side of the conveying device 1 is fixedly connected to a storage cylinder 10, and the rear side of the storage cylinder 10 is rotatably connected to a rotating cylinder 11. The outside of the storage cylinder 10 is fixedly connected and connected to a gas injection pipe 12, and the gas injection pipe 12 is connected to the external gas injection device. The front side of the storage cylinder 10 is provided with a blocking door 13 electrically connected to the control terminal, and the blocking door 13 is used to open and close the storage cylinder 10. The conveying device 1 is fixedly connected to an automatic unloading device 14 electrically connected to the control terminal. The automatic unloading device 14 is filled with tested and intact batteries for filling the screened out packaging failed batteries. A detection component for detecting whether the battery is swollen is provided below the fixing frame 2, and a correction component for correcting the battery orientation is provided outside the automatic unloading device 14. By screening out the batteries that catch fire and swell inside during the short-circuit test from the entire short-circuit test line and storing them in the storage cylinder 10, the battery short-circuit test line can be kept running quickly, thereby improving the rate of the battery short-circuit test.

[0033] like Figure 2 and Figure 5As shown, the detection component includes a second push rod 201 electrically connected to the control terminal, the second push rod 201 is fixedly connected to the bottom of the fixed frame 2, the telescopic end of the second push rod 201 is fixedly connected to the fixed cylinder 202, the fixed cylinder 202 is fixedly connected and communicated with the first airbag 203, the telescopic end of the second push rod 201 drives the first airbag 203 to fit with the required test battery through the fixed cylinder 202, the fixed cylinder 202 and the first airbag 203 cooperate to form a closed cavity, the first airbag 203 is squeezed when the battery expands, the first airbag 203 is deformed and contracted, the gas pressure inside the closed cavity formed by the fixed cylinder 202 and the first airbag 203 increases, the fixed cylinder 202 is fixedly connected to a pressure sensor 204 located in the closed cavity, the pressure sensor 204 is used to detect the pressure in the closed cavity formed by the fixed cylinder 202 and the first airbag 203, and the pressure sensor 204 is electrically connected to the control terminal.

[0034] like Figure 6 As shown, the correction component includes a first servo motor 301, which is fixedly connected to the left side of the outside of the automatic unloading device 14, and is electrically connected to the control terminal. The output shaft of the first servo motor 301 is fixedly connected to the first gear 302, and the outside of the automatic unloading device 14 is slidably connected to two rack racks 303 distributed in a mirror image, and the two rack racks 303 distributed in a mirror image are both engaged with the first gear 302. The output shaft of the first servo motor 301 drives the two rack racks 303 to move in opposite or opposite directions through the first gear 302, and the two rack racks 303 distributed in a mirror image are fixedly connected to the correction disk 304, and the contact surface between the correction disk 304 and the battery is a flexible surface to prevent the correction disk 304 from scratching the battery electrode, and the battery is pushed to be straightened by the two correction disks 304 to facilitate the next step.

[0035] When the battery preparation is completed, the battery needs to be short-circuited. The prepared battery moves from right to left following the conveying device 1 until the prepared battery stops at the detection position of the short-circuit tester 4. The conveying device 1 is turned off, and then the second push rod 201 is turned on. The telescopic end of the second push rod 201 drives the fixed cylinder 202 thereon to move downward, and the fixed cylinder 202 drives the first airbag 203 at its bottom to move downward synchronously, until the first airbag 203 is fitted with the detection battery, and then the second push rod 201 is closed, and the control device 3 is turned on, so that it drives the two docking plates 6 to dock with the two poles of the battery through the two docking frames 5 distributed in a mirror image, and then the control device 3 is closed, and the short-circuit tester 4 is turned on to perform a short-circuit test on the battery.

[0036] When the detected battery forms a closed loop and completes the short-circuit test, the second push rod 201 is turned on, and the telescopic end of the second push rod 201 drives the fixing cylinder 202 and the first airbag 203 to reset to the initial state. The control device 3 is turned on to drive the two docking plates 6 to separate from the two poles of the battery through the two docking frames 5, and then the conveying device 1 is turned on, and the conveying device 1 drives the detected battery to move to the left, and this cycle is repeated until the battery test is completed.

[0037] When the detected battery cannot form a closed loop, the second push rod 201 is turned on to reset the first airbag 203 to the initial state, and the docking plate 6 is separated from the two poles of the battery. Then the first push rod 7 and the external negative pressure device are turned on to make the suction cup 9 have suction, and the telescopic end of the first push rod 7 drives the suction cup 9 to contact the short-circuited battery. At this time, the suction cup 9 absorbs the battery, and then the telescopic end of the first push rod 7 is reset and drives the battery into the sliding rack 8 for screening through the suction cup 9. When the battery completely enters the sliding rack 8, the external negative pressure device is turned off, and the first push rod 7 is turned off. At this time, the battery enters the box below along the sliding rack 8. When the short circuit phenomenon occurs again, the above steps are repeated.

[0038] When the detected battery expands and catches fire, the battery squeezes the first airbag 203 that fits it, and the first airbag 203 is deformed by the squeezing force, which reduces the volume of the closed cavity matched with the first airbag 203 and the fixed cylinder 202, and increases the internal gas pressure. At this time, the pressure sensor 204 senses the pressure change and sends a signal to the control terminal, which opens the second push rod 201 to reset the first airbag 203 to the initial state, and at the same time, the docking plate 6 is separated from the two poles of the battery, and then the first push rod 7 and the blocking door 13 are opened, so that the blocking door 13 slides upward to release the storage cylinder 1 0, and then the blocking door 13 stops moving, and then the telescopic end of the first push rod 7 pushes the battery that begins to swell into the storage tube 10. When the swollen battery completely enters the storage tube 10, the first push rod 7 drives its telescopic rod to reset, and slides the blocking door 13 downward to block the storage tube 10 again. By screening out the batteries that catch fire and swell inside during the short-circuit test from the entire short-circuit test line and storing them in the storage tube 10, it is avoided that the battery explodes on the conveying device 1, resulting in the battery short-circuit test line being unable to continue to operate quickly, thereby reducing the rate of the battery short-circuit test.

[0039] Then, since the batteries that expanded and caught fire or failed internal packaging were screened to the outside of the assembly line, vacant positions of the batteries appeared on the conveyor 1, thereby reducing the subsequent packaging of the batteries. When the batteries on the conveyor 1 stopped at the automatic unloading device 14, the automatic unloading device 14 was turned on to replenish the vacant positions with batteries that had completed internal testing and were intact, ensuring that the batteries on the conveyor 1 were always in a full state and that the battery preparation could be carried out quickly.

[0040] After the automatic unloading device 14 replenishes the batteries to the idle position, the first servo motor 301 is turned on, and the output shaft of the first servo motor 301 drives the first gear 302 to rotate. The rotation of the first gear 302 drives the two mirror-distributed racks 303 to move in opposite directions. The two rack racks 303 drive the correction disks 304 thereon to move in opposite directions until they contact the placed batteries and correct their positions to avoid the batteries from being skewed when placed, which affects the subsequent preparation steps of the batteries.

[0041] After the expanded batteries were sorted into the storage cylinder 10, fire occurred inside the batteries, and the batteries were allowed to continue to expand, resulting in accumulation of high-pressure gas inside the batteries.

[0042] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes a puncture assembly for preventing the battery from continuing to expand. The puncture assembly is arranged in the storage tube 10. The puncture assembly includes a third push rod 401 electrically connected to the control terminal. The third push rod 401 is fixedly connected to the upper part of the outside of the storage tube 10. The telescopic end of the third push rod 401 is slidably connected to the storage tube 10. The telescopic end of the third push rod 401 is fixedly connected to a push frame 402 located inside the storage tube 10. The push frame 402 is fixedly connected to three plug shafts 403 in a linear array. The telescopic end of the third push rod 401 drives the three plug shafts 403 through the push frame 402 to puncture the outer shell of the battery that has not accumulated enough pressure , so that the gas generated by the fire inside it can be discharged to avoid continuous accumulation of pressure inside it, which may cause the battery to explode. The pushing frame 402 is slidably connected to the limiting plate 404. The three plug shafts 403 of the linear array are slidably connected to the limiting plate 404. The three plug shafts 403 of the linear array are located inside the limiting plate 404. Three elastic elements 405 of the linear array are arranged between the pushing frame 402 and the limiting plate 404. The elastic element 405 is a spring. The elastic element 405 is used to drive the limiting plate 404 to reset. The limiting plate 404 first contacts the battery and limits it to avoid sliding when the plug shaft 403 punctures its outer shell.

[0043] like Figure 4 and 7As shown, a fire prevention component for suppressing battery fire is also included, the fire prevention component is arranged in the rotating drum 11, and the fire prevention component includes a fourth push rod 406 electrically connected to the control terminal, the fourth push rod 406 is fixedly connected to the rear side of the outside of the conveying device 1 through a connecting piece, a push cylinder 407 is fixedly connected to the middle part of the rotating drum 11, the blocking door 13, the storage cylinder 10 and the rotating drum 11 cooperate to form a cavity, the push cylinder 407 is connected to the cavity formed by the storage cylinder 10, the rotating drum 11 and the blocking door 13, and the telescopic end of the fourth push rod 406 is fixedly connected to the rear side of the outside of the conveying device 1 through a connecting piece. A piston disk 408 is fixedly connected, and a push cylinder 407 is slidably connected to the piston disk 408. The telescopic end of the fourth push rod 406 drives the piston disk 408 to perform a linear reciprocating motion along the push cylinder 407, so that the pressure of the inert gas in the cavity formed by the storage cylinder 10, the rotating cylinder 11 and the blocking door 13 increases and decreases cyclically, and the inert gas in the cavity is pressed into the battery by simulating the principle of lung breathing, so that the inert gas fills the interior of the battery and timely suppresses the fire problem inside the battery. A storage component for storing expanded batteries is provided on the rotating cylinder 11.

[0044] like Figure 4 and 7 As shown, the storage assembly includes a second servo motor 501 electrically connected to the control terminal, the second servo motor 501 is fixedly connected to the rear side of the outside of the conveying device 1 through a connecting piece, the output shaft of the second servo motor 501 is fixedly connected to the second gear 502, the outside of the rotating drum 11 is fixedly connected to a gear ring 503 meshing with the second gear 502, the output shaft of the second servo motor 501 drives the rotating drum 11 to rotate through the second gear 502 and the gear ring 503, the interior of the rotating drum 11 is fixedly connected to six storage shells 504 in an annular array, the storage shells 504 are used to place damaged batteries, the rotating drum 11 is detachably connected to six disassembly covers 505 in an annular array, the six disassembly covers 505 in the annular array are respectively sealed and cooperated with adjacent storage shells 504, by collecting the damaged batteries into the storage shells 504 and treating them uniformly, it is avoided that the batteries need to be treated separately after short circuit expansion, thereby reducing the efficiency of battery testing.

[0045] When the expanded battery enters the storage cylinder 10, the pressure accumulated inside the battery is small, and the external gas injection device is turned on. The gas injection device injects inert gas into the cavity formed by the storage cylinder 10, the rotating cylinder 11 and the blocking door 13 through the gas injection pipe 12, and the third push rod 401 is turned on at the same time. The telescopic end of the third push rod 401 drives the push frame 402 to move downward, and the push frame 402 drives its upper limit plate 404 to move downward synchronously. The limit plate 404 first contacts the expanded battery, and because the lower part of the limit plate 404 is an arc-shaped plate, it is easier to fit with the battery to prevent it from sliding. The limit plate 404 continues to move downward to squeeze and fix the expanded battery, and then Afterwards, the telescopic end of the third push rod 401 drives the three plug shafts 403 of the linear array thereon to continue to move downward through the pushing frame 402. At the same time, the three elastic elements 405 of the linear array are compressed, and the three plug shafts 403 of the linear array move downward to puncture the swollen battery. By puncturing the swollen battery when sufficient pressure is not accumulated inside, the continuous accumulation of pressure inside the battery can be avoided to cause an explosion. When the battery ruptures, the telescopic end of the third push rod 401 drives the plug shaft 403 to reset through the pushing frame 402. At the same time, the elastic element 405 resets and drives the limit plate 404 to reset. When the swollen battery enters the storage tube 10 again, the above steps are repeated.

[0046] When the expanded battery ruptures, the inert gas in the storage cylinder 10 cannot enter the battery in time to suppress the fire. At this time, the fourth push rod 406 is opened, and the telescopic end of the fourth push rod 406 drives the piston plate 408 to perform linear reciprocating motion along the push cylinder 407. When the piston plate 408 slides inward along the push cylinder 407, the pressure of the inert gas in the cavity formed by the storage cylinder 10, the rotating cylinder 11 and the blocking door 13 increases, and the piston plate 408 is reset to restore the pressure inside the cavity. This cycle is repeated to simulate the principle of lung breathing, and the inert gas in the cavity is pressed into the battery, so that the inert gas fills the battery and suppresses the fire problem inside the battery in time. This cycle is repeated until the fire problem inside the battery disappears, and then the fourth push rod 406 is closed.

[0047] When the swollen battery appears again, the battery will push the batteries stored in the storage cylinder 10 when entering the storage cylinder 10. The batteries in the storage cylinder 10 are pushed into the storage shell 504 at the bottom of the rotating drum 11. When the battery enters the storage shell 504, the second servo motor 501 is turned on, and the output shaft of the second servo motor 501 drives the second gear 502 thereon to rotate. The second gear 502 rotates through the gear ring 503 to drive the rotating drum 11 to rotate. The rotating drum 11 drives the storage shells 504 in the internal annular array to rotate, so that the storage shells 504 without storing batteries rotate to the bottom of the rotating drum 11. This cycle is repeated to store the swollen batteries in the storage shells 504 of the rotating drum 11. When the storage shells 504 in the annular array are all filled with batteries, the staff opens the disassembly cover 505 to take out the damaged batteries in a unified manner. By collecting the damaged batteries in the storage shells 504 and putting them into unified processing, the work efficiency is improved.

[0048] Before performing a short-circuit test on the battery, since the battery goes through many processes during assembly, such as electrode stacking, winding and packaging, the two poles of the battery are very likely to be contaminated with grease. During the short-circuit test, the grease will isolate the flow of current, resulting in inaccurate battery short-circuit test.

[0049] Embodiment 3: Based on embodiment 2, Figure 9-12As shown, it also includes a cleaning component for cleaning the two poles of the battery, the cleaning component is arranged on the two docking racks 5 distributed in a mirror image, the cleaning component includes a third servo motor 601 electrically connected to the control terminal, the third servo motor 601 is fixedly connected to the left side of the adjacent docking rack 5, the two docking racks 5 distributed in a mirror image are jointly rotatably connected to a rotating shaft 602 fixedly connected to the output shaft of the third servo motor 601, the two docking racks 5 distributed in a mirror image are both rotatably connected to a rotating sleeve 603, the two rotating sleeves 603 distributed in a mirror image are both connected to the rotating shaft 602 through a pulley belt transmission, and the output shaft of the third servo motor 601 is driven by a pulley. The output shaft drives the two mirror-distributed rotating sleeves 603 to rotate through the rotating shaft 602, the pulley and the belt. The opposite sides of the two mirror-distributed rotating sleeves 603 are fixedly connected with the second airbags 604. The outside of the second airbags 604 is fixedly connected with the sponge 605, so that the second airbags 604 drive the adjacent sponges 605 to evenly fit the electrodes of the battery. The grease attached to the two poles of the battery is wiped off by the sponge 605 to avoid the grease blocking the flow of current and reducing the accuracy of circuit testing. The two mirror-distributed rotating sleeves 603 are both provided with inner channels 606, which are respectively connected to the external hot water injection device to The second airbag 604 is connected to the hot air injection device, and the inner shell 607 connected to the adjacent inner channel 606 is fixedly connected in the second airbag 604. The second airbag 604 is fixedly connected with uniformly distributed flow pipes 608. The uniformly distributed flow pipes 608 are all connected to the adjacent inner shell 607. The uniformly distributed flow pipes 608 are all connected to the adjacent sponge 605, so that hot water and high-temperature gas enter the sponge 605 through the inner channel 606, the inner shell 607 and the inner shell 607. The grease attached to the sponge 605 is softened by hot water. The fixing frame 2 is fixedly connected to two mirror-distributed cleaning shells 609 through a connecting piece, and the cleaning The shell 609 can wrap the adjacent second airbag 604. The two mirror-distributed cleaning shells 609 are fixedly connected with four cleaning soft shafts 610 in a circular array. The cleaning soft shafts 610 in the circular array are in contact and cooperation with the adjacent sponges 605, so that the sponge 605 fits with the four cleaning soft shafts 610 in the adjacent circular array, and the sponge 605 rotates and fits with the cleaning soft shafts 610 to form scrubbing. The bottom of the cleaning shell 609 is fixedly connected and connected with a liquid outlet pipe 611, so that hot water carries grease and is discharged along the liquid outlet pipe 611, so as to avoid excessive grease on the sponge 605 and fail to clean the grease attached to the two poles of the battery.

[0050] Before the short-circuit test of the battery, since the two poles of the battery will be stained with grease, the grease will isolate the flow of current, resulting in inaccurate battery short-circuit test. Before the short-circuit test of the battery, the control device 3 drives the two second airbags 604 through the two docking frames 5 to make the sponge 605 contact the two poles of the battery. The second airbags 604 can be flexibly deformed to make the sponge 605 evenly fit the two poles of the battery. Then the third servo motor 601 is turned on, and the output shaft of the third servo motor 601 drives the rotating shaft 602 to rotate. The rotating shaft 602 rotates and drives the two rotating shafts 602 through the belt and the pulley. The sleeve 603 rotates, and the rotating sleeve 603 drives the adjacent second airbag 604 to rotate. The rotation of the second airbag 604 drives the external sponge 605 to rotate synchronously, so that the sponge 605 wipes off the grease attached to the two poles of the battery, and this is done until the grease on the two poles of the battery is cleaned up, and then the third servo motor 601 is turned off. At the same time, the control device 3 drives the two second airbags 604 to reset to the initial state through the docking frame 5, waiting for the cleaning of the next battery, to avoid grease in the subsequent short-circuit test. Grease blocks the flow of current and reduces the accuracy of the circuit test. This cycle is repeated until the battery short-circuit test is completed.

[0051] When sponge 605 cleans the grease on the two poles of the battery, the grease will continue to adhere to the outside of sponge 605, making it difficult for sponge 605 to clean the grease on the two poles of the battery. The control device 3 needs to regularly drive the two second air bags 604 into the adjacent cleaning shells 609 through the two docking frames 5, and make the sponge 605 contact with the four cleaning flexible shafts 610 of the annular array, and then turn on the external hot water injection device, and the hot water enters the inner shell 607 along the inner channel 606, and enters the evenly distributed circulation pipes 608 from the inner shell 607, and finally enters the sponge 605 from the circulation pipes 608, and then enters the cleaning shell 609 from the sponge 605, at this time, the third servo motor 601 is turned on, and the output shaft of the third servo motor 601 drives the two second air bags 604 to rotate The cleaning shaft 610 is moved to rotate in an offset manner with the adjacent sponge 605, so that the cleaning shaft 610 scrubs the adjacent sponge 605, and at the same time, the grease attached to the outside is softened with the help of hot water, and the grease is carried into the cleaning shell 609 and discharged uniformly along the liquid outlet pipe 611 at the bottom thereof. When the sponge 605 is cleaned, the external hot water injection device is closed, and the hot air injection device is switched to the hot air injection device. At this time, the high-temperature gas enters the sponge 605 along the inner channel 606, the inner shell 607 and the circulation tube 608, dries the moisture inside the sponge 605, and squeezes the moisture inside the sponge 605 with the help of the cleaning shaft 610, so that the sponge 605 becomes dry, and then the external hot air injection device is closed, and the control device 3 drives the two second airbags 604 to reset to the initial state through the docking frame 5, waiting for the cleaning of the battery poles.
