According to the different appearance structures, lithium batteries are mainly divided into three types: cylindrical, square and soft pack. Among them, cylindrical lithium batteries have become one of the most widely used battery forms in industrial applications due to their advantages such as structural stability, high mechanical strength, excellent heat dissipation performance and mature production technology. They are especially widely used in new energy vehicle power battery packs and high-rate discharge equipment.

[0003] The packaging process of cylindrical lithium batteries mainly includes key steps such as shell preparation, tab welding, liquid injection, sealing and testing. Among them, the sealing process is the core link of the entire packaging process, which directly affects the sealing, safety and service life of the battery. At present, cylindrical lithium batteries are generally sealed by mechanical stamping, that is, the top of the battery shell is extruded by the mold to make the shell material bend inward to form a closed seal. However, after long-term use of this method, the contact surface between the stamping mold and the lithium battery will show local wear, resulting in an uneven stamping contact surface between the mold and the lithium battery, causing the stamping mold to have uneven force when stamping and sealing the lithium battery, which can easily cause overvoltage or undervoltage in local areas, thereby affecting the sealing quality, resulting in a decrease in sealing performance, and even causing safety hazards such as electrolyte leakage or gas escape, thereby restricting the improvement of the overall performance of the battery.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] At present, cylindrical lithium batteries are generally sealed by mechanical stamping, that is, pressure is applied to the top of the battery shell through a mold, causing the shell material to bend inward and achieve a seal. However, during long-term use, the contact area between the stamping mold and the battery is prone to local wear, resulting in an uneven contact surface. This causes the mold to be unevenly stressed when applying pressure to seal the battery, which is prone to local overpressure or insufficient pressure, thereby affecting the uniformity and sealing quality of the seal. The deterioration of sealing performance may lead to safety hazards such as electrolyte leakage or internal gas leakage, seriously affecting the safety and reliability of the battery and limiting the further improvement of its overall performance.

[0029] Example 1

[0030] This embodiment discloses a packaging device for automobile lithium battery production, which is used to improve its sealing strength.

[0031] like Figure 1-Figure 5As shown, it includes a packaging table 1, which is provided with a clamping table 2 for clamping lithium batteries. The clamping table 2 is an existing electric three-jaw chuck, and the clamping parts can be pieced together into a cylinder, which can wrap the cylindrical lithium battery inside. The packaging table 1 is fixedly connected to a power module 3, which is a hydraulic push rod in this embodiment. The telescopic end of the hydraulic push rod is fixedly connected to the lower side of the slide 4. The packaging table 1 is slidably connected to the slide 4. The power module 3 is used to drive the slide 4 to move up and down along the packaging table 1. The slide 4 is fixedly connected to the mold 5. The middle part of the mold 5 is provided with a cylindrical through hole and an annular arc surface for guiding the bending of the top shell of the lithium battery. A swivel 6 is rotatably connected to the mold 5. The mold 5 and the swivel 6 cooperate to form an upper mold for stamping the lithium battery, and the clamping table 2 forms a lower mold for stamping the lithium battery after clamping the lithium battery. The two are spliced ​​together. Into stamping, the mold 5 is used to guide the outer shell of the top of the lithium battery to bend inward, the swivel 6 is used to extrude the bent lithium battery shell, the swivel 6 is slidably connected to the circumferentially distributed adjustment frame 7, in this embodiment, the sliding direction of the adjustment frame 7 and the swivel 6 is only up and down sliding, the number of adjustment frames 7 can be freely set, this embodiment adopts a number of four, and they are evenly spaced circumferentially distributed on the swivel 6, the bottom of the adjustment frame 7 is provided with a ball 8 for rolling sealing, the ball 8 is combined with the stamped lithium battery top and rolls it to improve the sealing strength of the lithium battery seal, the initial state The bottom of the ball 8 is higher than the lower side of the swivel 6, so that the lithium battery shell is preferentially stamped and sealed under the cooperation of the mold 5 and the swivel 6, a driving component for driving the swivel 6 to rotate is provided on the slide 4, and a protrusion component for synchronously changing the position of all adjustment frames 7 is provided in the mold 5.

[0032] like Figures 1-4 As shown, the drive assembly includes a servo motor 201, which is fixedly connected to the upper side of the skateboard 4. The output shaft of the servo motor 201 is fixedly connected to the first gear 202. The upper side of the skateboard 4 is rotatably connected to a second gear 203 that meshes with the first gear 202. The interior of the second gear 203 is fixedly connected to a coaxially rotating rotating frame 204. The rotating frame 204 is fixedly connected to the swivel 6, and the two also rotate coaxially. A stabilizing component for stabilizing the lithium battery pole is provided on the rotating frame 204.

[0033] like Figure 3As shown, the stabilizing assembly includes a sliding shaft 301, which is slidably connected to the inside of the rotating frame 204, and the sliding shaft 301 passes through the rotating ring 6. A centering block 302 is fixedly connected to the bottom of the sliding shaft 301. The radius of the centering block 302 is smaller than the inner diameter of the rotating ring 6, so that the centering block 302 can pass through the rotating ring 6. In the initial state, the upper side of the centering block 302 is lower than the lower side of the rotating ring 6, so as to preferentially contact the pole of the lithium battery before the lithium battery shell is bent. A first elastic member 303 is provided between 1 and the rotating frame 204. The first elastic member 303 is a tension spring, which is used to drive the sliding shaft 301 to reset and generate a force on the lithium battery pole through the sliding shaft 301 and the centering block 302 to improve the stability of the lithium battery pole. The central axis of the sliding shaft 301, the central axis of the centering block 302, the central axis of the rotating ring 6 and the central axis of the mold 5 all coincide. The lower side of the centering block 302 is provided with an inclined surface for centering the lithium battery pole.

[0034] Working principle: When it is necessary to seal a lithium battery, first place the lithium battery to be sealed on the clamping table 2, then start the clamping table 2 to clamp the lithium battery. After clamping is completed, turn on the power module 3, and the telescopic end of the power module 3 starts to drive the slide 4 to move downward. The mold 5 and the slide 4 move downward synchronously, so that the mold 5 is docked with the clamping table 2, and then stop the power module 3. During this period, the mold 5 will apply an extrusion force to the top of the lithium battery shell. Under the action of pressure, the top of the lithium battery shell is bent inward along the lower side of the swivel 6 to form a seal. Then, turn on the power module 3, so that the slide 4 drives the mold 5 to move upward for a certain distance (this distance allows the ball 8 to drop and contact the top of the battery), and then turn off the power module 3. , and through the protruding components, several adjustment frames 7 drive the balls 8 thereon to move downward and fit with the top of the lithium battery, and then start the servo motor 201. The output shaft of the servo motor 201 drives the circumferentially distributed adjustment frames 7 to rotate synchronously through the first gear 202, the second gear 203, the rotating frame 204 and the swivel 6. The balls 8 on the adjustment frames 7 perform circular motion around the top of the lithium battery. Driven by the adjustment frames 7, the balls 8 fit the sealing area on the top of the lithium battery and perform a rolling operation. The rolling action of the balls 8 applies uniform pressure to the outer shell at the seal, further compacting the outer shell at the seal on the top of the lithium battery, ensuring that the outer shell at the seal of the lithium battery is tightly fitted to the top of the lithium battery, and improving the firmness and sealing of the seal.

[0035] After the circumferentially distributed adjustment racks 7 rotate several times (the specific number of turns can be freely set according to actual conditions), the servo motor 201 is turned off, and the several adjustment racks 7 are driven to reset through the extension assembly. At the same time, the power module 3 is turned on, so that the telescopic end of the power module 3 drives the slide 4 to reset, the mold 5 is separated from the lithium battery, and then the clamping table 2 is opened to release the clamping of the lithium battery, and the sealed lithium battery is taken out. At this time, the sealing of the lithium battery is completed. When it is necessary to continue the sealing operation on the lithium battery, repeat the above steps.

[0036] When the telescopic end of the power module 3 drives the mold 5 to move downward through the slide plate 4, the mold 5 drives the internal sliding shaft 301 to move synchronously, and the sliding shaft 301 drives the centering block 302 at the bottom to move synchronously. The centering block 302 is initially located below the rotating ring 6. Before the lithium battery bends inward, the centering block 302 first contacts the pole inside the lithium battery. The pole inside the lithium battery is concentric with the outer shell of the lithium battery under the pressure of the inclined surface of the lower side of the centering block 302. At the same time, as the mold 5 gradually drives the centering block 302 to move downward, The pole in the lithium battery generates an upward squeezing force on the centering block 302, so that the centering block 302 drives the sliding shaft 301 to move upward synchronously, and at the same time the first elastic member 303 is stretched, and this is done until the power module 3 stops driving the slide plate 4 to move, and the battery sealing is completed. The centering block 302 contacts the pole in the lithium battery in advance, and squeezes each other to correct and stabilize it, so that the pole of the lithium battery and the battery shell are in a concentric state, reducing the probability of the pole of the lithium battery being deflected, and improving the quality of the lithium battery itself after packaging.

[0037] After the lithium battery is packaged, when the mold 5 is reset, the centering block 302 is gradually separated from the pole of the lithium battery, and the extrusion force between the two disappears. The first elastic member 303 drives the centering block 302 to reset through the sliding shaft 301. When the lithium battery needs to be sealed again, repeat the above steps.

[0038] Example 2

[0039] This embodiment discloses a packaging device for automotive lithium battery production, which is further improved on the basis of Example 1.

[0040] like Figure 3-Figure 7As shown, the protruding component includes a rotating ring 401, the mold 5 is fixedly connected to the connecting frame, the rotating ring 401 is rotatably connected to the connecting frame in the mold 5, the rotating ring 401 is slidably connected to the sliding frame 402 up and down, and the bottom of the sliding frame 402 is fixedly connected to the pushing frame 403 with the same number as the adjusting frame 7, the pushing frame 403 is slidably connected to the corresponding adjusting frame 7, and the pushing frame 403 deflects outward from top to bottom with the central axis of the sliding frame 402, and is used to drive the adjusting frame 7 to slide horizontally. A second elastic member 404 is provided between the pushing frame 403 and the corresponding adjusting frame 7, and the second elastic member 404 is a spring. The second elastic member 404 is used to drive the adjusting frame 7 to reset and apply a force to the adjusting frame 7 to stabilize the position of the adjusting frame 7, so that the pushing frame 403 stably drives the adjusting frame 7 to move synchronously; the rotating ring 6 is provided with the same number of guide grooves as the adjusting frame 7, and the adjusting frame 7 and the inner and outer guide grooves of the adjusting frame 7 are connected. The first clamping block 405 slides in the adjacent first sliding grooves 406. The first sliding groove 406 is a horizontally placed L-shaped groove for controlling the contact time of the ball 8 and the lithium battery. The short groove of the L-shaped groove is located at the top, and the first clamping block 405 slides downward along the top of the short groove of the first sliding groove 406 to the inflection point with the long groove, that is, the adjusting frame 7 drives the ball 8 to protrude out of the rotating ring 6, and the ball 8 fits and squeezes the outer edge of the top of the lithium battery. When the first clamping block 405 slides from the inflection point of the short groove and the long groove to the limit of the long groove, the ball 8 moves inward from the outer edge of the lithium battery, continuously changing the rolling radius on the top of the lithium battery.

[0041] like Figure 7 and Figure 8As shown, the mold 5 is slidably connected to an adjusting shaft 501, and the adjusting shaft 501 is limitedly slidably connected to the sliding frame 402, so as to enable the adjusting shaft 501 to drive the sliding frame 402 to move synchronously. The top of the adjusting shaft 501 is fixedly connected to a second clamping block 502, and the rotating frame 204 is provided with a second slide groove 503. The second clamping block 502 slides in the second slide groove 503. The second slide groove 503 is composed of a plurality of arc grooves and a plurality of inclined slide grooves arranged alternately. Both sides of the second slide groove 503 are inclined slide grooves. The center angle of the arc formed between the two adjacent balls 8 is smaller than the second The center angle corresponding to the arc groove in the slide groove 503 is used to ensure that the rolling trajectory of all balls 8 on the top of the lithium battery is a closed circle at different rolling radii, thereby improving the uniformity of rolling. In the initial state, the second block 502 is located at the top of the top inclined slide groove, and the rotating frame 204 rotates to drive the adjusting shaft 501 to move downward, so that the adjusting shaft 501 drives the ball 8 to fit with the top of the lithium battery through the sliding frame 402, the pushing frame 403 and the adjusting frame 7. At this time, the second block 502 enters the arc groove, and the ball 8 begins to roll the top of the lithium battery.

[0042] Working principle: When rolling the top of the lithium battery, the servo motor 201 is turned on, and the output shaft of the servo motor 201 drives the rotating frame 204 to rotate through the first gear 202 and the second gear 203. At this time, the rotating frame 204 rotates and drives the second slide 503 thereon to rotate synchronously. The second slide 503 rotates to push the second block 502 to move downward, and the second block 502 drives the adjusting shaft 501 to move downward synchronously. The adjusting shaft 501 pushes the sliding frame 402 to move downward along the rotating ring 401, and the sliding frame 402 drives all the pushing frames 403 thereon to move downward synchronously, so that the pushing frame 403 drives the adjusting frame 7 to move downward synchronously with the force of the second elastic member 404 on the adjacent adjusting frame 7, and the second elastic member 404 is not compressed. At this time, the first block 405 on the adjusting frame 7 moves along the adjacent first The slide groove 406 slides downward, so that the ball 8 on the adjustment frame 7 fits with the top of the lithium battery, and then the first block 405 slides to the inflection point of the first slide groove 406, and then the adjusting shaft 501 continues to move downward, and the pushing frame 403 pushes the adjacent adjusting frame 7 to continue to slide along the first slide groove 406, so that the ball 8 on the adjustment frame 7 moves from the outside of the top of the lithium battery to the inside, and the second elastic member 404 is compressed, so as to complete the rolling operation of the lithium battery by making the ball 8 fit the outside of the top of the lithium battery and gradually move from the outside to the inside, constantly changing the rolling radius of the ball 8 on the lithium battery, and evenly pressing the shell at the top seal of the lithium battery to ensure that the shell at the lithium battery seal fits tightly against the top of the lithium battery, thereby improving the firmness and sealing of the seal.

[0043] When the rolling operation of the lithium battery is completed, the staff drives the slide plate 4 to reset through the power module 3, and at the same time the output shaft of the servo motor 201 rotates in the opposite direction, so that the rotating frame 204 drives the second slide groove 503 thereon to rotate in the opposite direction, and the second slide groove 503 drives the adjustment shaft 501 to reset to the initial state through the second block 502. During this period, the adjustment shaft 501 drives several adjustment frames 7 to reset to the initial state synchronously through the sliding frame 402 and the pushing frame 403, and at the same time the second elastic member 404 resets to the initial state. When the lithium battery needs to be sealed again, repeat the above steps.

[0044] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
