Description

Technical Field

[0001] This invention belongs to the field of lithium battery processing technology, and specifically relates to an automatic lithium battery packaging machine. Background Technology

[0002] Lithium-ion batteries are rechargeable secondary batteries that use lithium ions as the working medium. With their advantages such as high energy density, long cycle life, low self-discharge rate, and no memory effect, they have been widely used in many fields such as portable electronic devices, electric vehicles, energy storage systems, and aerospace. According to different shapes and structures, lithium batteries are mainly divided into three types: cylindrical, square, and pouch. Among them, cylindrical lithium batteries have become one of the most widely used battery forms in industrial applications due to their advantages such as stable structure, high mechanical strength, excellent heat dissipation performance, and mature manufacturing process. They are especially widely used in power battery packs for new energy vehicles and high-rate discharge equipment.

[0003] Existing technologies also offer some solutions: for example, a patent with publication number CN118538977B discloses a packaging equipment for automotive lithium battery production, including a packaging platform. The packaging platform is equipped with a clamping platform for holding lithium batteries. A power module is fixedly connected to the packaging platform, and a sliding plate is slidably connected to the packaging platform. After the lithium battery is mechanically stamped, the sealing position is rolled by ball bearings. The rolling action of the ball bearings applies uniform pressure to the outer shell at the sealing position, further compacting the outer shell at the top sealing position of the lithium battery, ensuring that the outer shell at the sealing position of the lithium battery fits tightly against the top of the lithium battery, and improving the firmness and sealing performance of the seal.

[0004] In existing technologies, the lithium battery packaging process largely relies on manual material handling. Manual material handling is not only inefficient and increases labor costs, but it is also prone to errors that can lead to misalignment of the battery casing and lithium battery pack, resulting in problems such as incomplete packaging and unstable battery performance, which affect the consistency of product quality. Furthermore, manual operation is difficult to adapt to the needs of large-scale, automated production, thus limiting production efficiency.

[0005] Therefore, the present invention provides an automatic lithium battery packaging machine. Summary of the Invention

A thrust component is provided on one side of the feeding hopper, which is used to push the lithium battery packs to move. A battery cover is provided between the feeding hopper and the feeding hopper, and a packaging component is arranged on top of it, which can drive the battery cover to move downward.

[0008] Preferably, the power assembly includes two fixed slides, which are respectively fixedly connected to both sides of the encapsulation stage. The inner walls of each fixed slide are fixedly connected to multi-stage telescopic rods, and one end of each multi-stage telescopic rod is fixedly connected to an inner slider. The inner slider is slidably connected to the inner wall of the fixed slide, and the two inner sliders are fixedly connected to both sides of the push plate.

[0009] Preferably, a limiting plate is symmetrically fixedly connected to the surface of the encapsulation stage, and a blocking plate is symmetrically fixedly connected to the top of the encapsulation stage, with the blocking plate located on one side of the positioning plate.

[0010] Preferably, the hook assembly includes two connecting rods, each of which is fixedly connected to one end of the inner slider. A hinge is fixedly connected to one end of each connecting rod, and a hook plate is fixedly connected to the shaft of each hinge. A torsion spring is fixedly connected between the hook plate and the connecting rod. Side plates are fixedly connected to both sides of the positioning plate, and an extension plate is fixedly connected to one side of each side plate.

[0011] Preferably, a locking ball is fixedly connected to one side of the connecting rod, the outer wall of the locking ball is in contact with one side of the hook plate, and a separation component is provided at the bottom of the hook plate to drive the hook plate to rotate again.

[0012] Preferably, the separation assembly includes two connectors, which are respectively fixedly connected to one side of the fixed slide. A rack plate is fixedly connected to the top of each connector, and a gear is fixedly connected to the bottom of the shaft of the hinge. The teeth of the gear can mesh with the teeth of the connector.

[0013] Preferably, the surface of the packaging platform is symmetrically provided with sliding grooves, and the bottom of the positioning plate is symmetrically fixedly connected with bottom sliders. The bottom sliders are slidably connected to the sliding grooves, and a return spring is fixedly connected to one side of each bottom slider. The end of the return spring away from the bottom slider is fixedly connected to the inner wall of the sliding groove.

[0014] Preferably, the thrust assembly includes a fixed platform, which is fixedly connected to one side of the discharge bin body one, and the discharge bin body two is fixedly connected to the top of the fixed platform.

At the same time, the pushing component precisely controls the pushing of the lithium battery pack, ensuring that it lands accurately above the battery casing. When the packaging component lowers the battery cover, it can also accurately push the lithium battery pack into the battery casing and seal the top.

[0018] 2. The automatic lithium battery packaging machine of the present invention, after packaging is completed, the power component drives the push plate to move in the reverse direction and reset, and the hook component makes the positioning plate move synchronously with it, pushing the packaged battery shell along the surface of the packaging stage to the top edge of the tilting stage. In this process, the hook component ensures the coordinated action of the positioning plate and the push plate, so that the battery shell can be pushed smoothly and smoothly to the unloading position. When the battery shell reaches the top edge of the tilting stage, the hook component automatically releases the connection between the positioning plate and the push plate, and the positioning plate immediately reverses and resets, preparing for the next round of packaging operation. At the same time, the battery shell can slide naturally down the inclined surface of the tilting stage to complete the unloading, ensuring the smoothness and efficiency of the unloading process.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 8 As shown, the present invention provides a technical solution: an automatic lithium battery packaging machine, including a packaging platform 1, a feeding bin 2 fixedly connected to the top of the packaging platform 1, which contains multiple battery casings 3, a pusher plate 4 on one side of the feeding bin 2 and a positioning plate 5 on the other side, the positioning plate 5 being slidably connected to the packaging platform 1, an inclined platform 6 fixedly connected to one side of the packaging platform 1, a power component on one side of the pusher plate 4, which can drive the pusher plate 4 to move along the surface of the packaging platform 1, hook components on both sides of the pusher plate 4 for connecting the pusher plate 4 and the positioning plate 5 to achieve synchronous movement, a feeding bin 26 on one side of the feeding bin 2, which contains multiple lithium battery packs 27 neatly stacked longitudinally, a thrust component on one side of the feeding bin 26 for pushing the lithium battery packs 27 to move, a battery cover 34 between the feeding bin 2 and the feeding bin 26, and a packaging component on top of the battery cover 34 for moving downwards.

[0024] During operation: Multiple battery casings 3 are placed into the first feeding chamber 2 in sequence to form a vertical stack; similarly, multiple lithium battery packs 27 are placed into the second feeding chamber 26 and stacked vertically in the same way. During encapsulation, the battery cover plate 34 is first assembled with the encapsulation component. The power component is then started, driving the pusher plate 4 to move along the surface of the encapsulation platform 1. The pusher plate 4 pushes the bottom battery casing 3 in the unloading chamber 2 to move, while its top prevents the other battery casings 3 from falling. After the bottom battery casing 3 is pushed to one side of the positioning plate 5, it is accurately positioned to the encapsulation position (i.e., one side of the positioning plate 5) under the continuous pushing force of the pusher plate 4 and the restriction of the positioning plate 5. The thrust assembly is activated, pushing the lithium battery pack 27 at the bottom of the unloading chamber 26 to the top of the battery casing 3 at the encapsulation position; the encapsulation assembly drives the battery cover 34 to descend, first pushing the lithium battery pack 27 completely into the battery casing 3, achieving initial encapsulation of the lithium battery pack 27 and the battery casing 3; then the battery cover 34 continues to descend, sealing the top of the battery casing 3. At this point, the encapsulation assembly and the battery cover 34 disengage, and the battery cover 34 and the top of the battery casing 3 complete the final encapsulation. The encapsulation assembly rises to reset, and the thrust assembly moves in the opposite direction to reset. The power component drives the pusher plate 4 to move in the reverse direction and reset. The hook component makes the positioning plate 5 move synchronously with the pusher plate 4. The positioning plate 5 pushes the packaged battery casing 3 along the surface of the packaging stage 1. When the battery casing 3 passes the unloading chamber 2, the remaining battery casing 3 applies pressure to it to further compact the packaging structure. After the positioning plate 5 enters the unloading chamber 2, it supports the remaining battery casing 3 above to prevent it from falling naturally. When the positioning plate 5 pushes the packaged battery casing 3 to the top edge of the tilting stage 6, the hook component automatically releases the connection between the positioning plate 5 and the pusher plate 4. The positioning plate 5 immediately resets in the reverse direction, and the battery casing 3 slides down the inclined surface of the tilting stage 6 to complete the unloading. After the positioning plate 5 resets, the remaining battery casing 3 in the unloading chamber 2 automatically falls down to wait for the next round of packaging. Through the above embodiments, during the encapsulation process, the continuous pushing force of the pusher plate 4 and the limiting effect of the positioning plate 5 accurately position the battery casing 3 to the encapsulation position. Simultaneously, the pushing component precisely controls the pushing of the lithium battery pack 27, ensuring it lands precisely above the battery casing 3. When the encapsulation component lowers the battery cover plate 34, it also accurately pushes the lithium battery pack 27 into the battery casing 3 and seals the top. This precise positioning and encapsulation method effectively avoids problems such as incomplete encapsulation and unstable battery performance caused by positional deviations, ensuring the consistency and reliability of product quality. After encapsulation is completed, the power component drives the pusher plate 4 to move in the reverse direction. The automatic reset and hook assembly cause the positioning plate 5 to move synchronously with it, pushing the packaged battery casing 3 along the surface of the packaging stage 1 to the top edge of the tilting stage 6. During this process, the hook assembly ensures the coordinated action of the positioning plate 5 and the push plate 4, so that the battery casing 3 can be pushed smoothly and easily to the unloading position. When the battery casing 3 reaches the top edge of the tilting stage 6, the hook assembly automatically releases the connection between the positioning plate 5 and the push plate 4, and the positioning plate 5 immediately reverses and resets, preparing for the next round of packaging operation. At the same time, it allows the battery casing 3 to slide naturally down the inclined surface of the tilting stage 6 to complete the unloading, ensuring the smoothness and efficiency of the unloading process.

[0025] like Figures 2 to 3 As shown, the power assembly includes two fixed slides 7, which are fixedly connected to both sides of the encapsulation platform 1. The inner walls of the fixed slides 7 are fixedly connected to multi-stage telescopic rods 8, and one end of each multi-stage telescopic rod 8 is fixedly connected to an inner slider 9. The inner slider 9 is slidably connected to the inner wall of the fixed slides 7, and the two inner sliders 9 are fixedly connected to both sides of the push plate 4.

[0026] During operation: The multi-stage telescopic rod 8 retracts, causing the inner slider 9 to slide along the inner wall of the fixed slide block 7, thereby moving the push plate 4 along the surface of the encapsulation stage 1. When the push plate 4 enters the unloading chamber 2, it pushes the bottom battery casing 3 along the surface of the encapsulation stage 1. At the same time, the top of the push plate 4 supports the remaining battery casings 3 in the unloading chamber 2, preventing the remaining battery casings 3 from falling naturally due to gravity after the bottom battery casing 3 leaves, thus avoiding affecting the subsequent positioning plate 5 pushing the encapsulated battery casing 3 through the bottom of the unloading chamber 2. When the battery casing 3 is pushed to one side of the positioning plate 5, the positioning plate 5 is restricted from moving in the direction of force application. Under the combined action of the push plate 4 and the positioning plate 5, the battery casing 3 is accurately positioned in the encapsulation position. Similarly, after encapsulation is completed, the multi-stage telescopic rod 8 extends, causing the push plate 4 to move in the opposite direction along the surface of the encapsulation stage 1 to reset, thereby performing the unloading operation.

[0027] like Figure 3As shown, a limiting plate 10 is symmetrically fixedly connected to the surface of the packaging stage 1, and a blocking plate 11 is symmetrically fixedly connected to the top of the packaging stage 1. The blocking plate 11 is located on one side of the positioning plate 5.

[0028] During operation: When the pusher plate 4 pushes the battery casing 3 closer to the positioning plate 5 through the set limit plate 10, it restricts both sides of the battery casing 3 to prevent the battery casing 3 from shifting position when it is pushed again. Through the set blocking plate 11, the positioning plate 5 and the packaging stage 1 are slidably connected. The blocking plate 11 can prevent the pushing plate 4 from continuing to push the positioning plate 5 to the side of the pushing force when the battery casing 3 stops on one side of the positioning plate 5.

[0029] like Figures 5 to 7 As shown, the hook assembly includes two connecting rods 15, which are respectively fixedly connected to one end of the inner slider 9. A hinge 16 is fixedly connected to one end of each connecting rod 15. A hook plate 17 is fixedly connected to the shaft of each hinge 16. A torsion spring 18 is fixedly connected between the hook plate 17 and the connecting rod 15. Side plates 20 are fixedly connected to both sides of the positioning plate 5. An extension plate 19 is fixedly connected to one side of each side plate 20.

[0030] During operation: The power unit drives the pusher plate 4 to move the battery casing 3 along the surface of the encapsulation platform 1, simultaneously moving the hook plate 17 towards the extension plate 19. When the hook plate 17 passes the extension plate 19, its outer wall is squeezed by the outer wall of the extension plate 19 and rotates inward around the hinge 16 shaft, compressing the torsion spring 18 and causing deformation. After the battery casing 3 is pushed to one side of the positioning plate 5, the hook plate 17 moves to the outside of the side plate 20. After losing the squeezing force of the extension plate 19, it automatically resets under the elastic force of the torsion spring 18; After installation, the power unit drives the push plate 4 to move in the reverse direction to reset. At this time, the end of the hook plate 17 hooks onto the side wall of the side plate 20, causing the positioning plate 5 to move synchronously along the surface of the encapsulation stage 1. This applies a pushing force to the encapsulated battery casing 3, causing it to leave the encapsulation position and eventually move to the top edge of the tilting stage 6. After the push plate 4 and the positioning plate 5 are disconnected, the push plate 4 is completely reset to its original position, and the battery casing 3 located at the top edge of the tilting stage 6 will slide off the surface of the tilting stage 6.

[0031] like Figures 5 to 7 As shown, a locking ball 21 is fixedly connected to one side of the connecting rod 15. The outer wall of the locking ball 21 is in contact with one side of the hook plate 17. A separation component is provided at the bottom of the hook plate 17 to drive the hook plate 17 to rotate again.

[0032] During operation: The locking ball 21 physically abuts and limits the hinge rotation angle range of the hook plate 17. When one end of the hook plate 17 hooks onto the outer wall of the side plate 20 and moves it, the locking ball 21 can effectively prevent the hook plate 17 from rotating unexpectedly around the hinge 16 due to the reverse force, ensuring that the hook plate 17 and the side plate 20 always maintain a stable hook connection, avoiding the failure of the positioning plate 5 to move due to disengagement; when the positioning plate 5 moves the encapsulated battery shell 3 to the top edge of the tilting platform 6, the separation component drives the hook plate 17 to force a hinge rotation at the shaft of the hinge 16, so that the hook plate 17 disengages from the side plate 20, thereby facilitating the positioning plate 5 to move back to its original position, and the push plate 4 can move back to its original position independently.

[0033] like Figures 5 to 7 As shown, the separation assembly includes two connectors 23, which are fixedly connected to one side of the fixed slide 7. A rack plate 24 is fixedly connected to the top of each connector 23. A gear 22 is fixedly connected to the bottom of the shaft of the hinge 16. The teeth of the gear 22 can mesh with the teeth of the connector 23.

[0034] During operation: Connector 23 and rack plate 24 are connected by a lifting rod. When push plate 4 moves forward for the first time, the lifting rod is in the raised state, which drives rack plate 24 to move up above gear 22. At this time, gear 22 and rack plate 24 are completely separated. Hook plate 17 is subject to the one-way limiting action of locking ball 21 and can rotate normally around the axis of hinge 16 to pass over extension plate 19. When hook plate 17 passes over extension plate 19 and hooks side plate 20, push plate 4 drives positioning plate 5 to move together. The lifting rod descends, so that the teeth of rack plate 24 and gear 22 are precisely meshed. When push plate 4 drives positioning plate 5 to push battery casing 3 to the edge of tilting platform 6, gear 22 rotates under the guidance of rack plate 24, which in turn drives hook plate 17 to swing inward against the spring force of torsion spring 18, realizing forced separation from side plate 20.

[0035] like Figures 3 to 4 As shown, the surface of the packaging platform 1 is symmetrically provided with sliding grooves 13, and the bottom of the positioning plate 5 is symmetrically fixedly connected with bottom sliders 12. The bottom sliders 12 are slidably connected to the sliding grooves 13. Each side of the bottom sliders 12 is fixedly connected with a return spring 14, and the end of the return spring 14 away from the bottom sliders 12 is fixedly connected to the inner wall of the sliding grooves 13.

[0036] During operation: When the push plate 4 moves in the opposite direction, driving the positioning plate 5 to move together, the bottom slider 12 and the slide 13 act as guides to ensure that the positioning plate 5 pushes the battery casing 3 to the tilting platform 6 along a straight path. When the positioning plate 5 moves, the return spring 14 is stretched and deformed. After the separation assembly cancels the connection between the push plate 4 and the positioning plate 5, the positioning plate 5 can be reset to its original position by the return spring 14, while the push plate 4 continues to move back to its original position. At this time, the battery casing 3 can slide off the inclined surface of the tilting platform 6.

[0037] like Figure 8 As shown, the thrust assembly includes a fixed platform 25, which is fixedly connected to one side of the first feeding bin 2, and the second feeding bin 26 is fixedly connected to the top of the fixed platform 25. A docking groove 30 is provided on the surface of the fixed platform 25, and a second pusher plate 28 is slidably connected to the surface of the fixed platform 25. A cylinder 29 is fixedly installed on the top of the fixed platform 25, and the output end of the cylinder 29 is fixedly connected to one side of the second pusher plate 28.

[0038] During operation: When the battery casing 3 is pushed to one side of the positioning plate 5 by the pusher plate 4, the cylinder 29 is activated, and the pusher plate 28 pushes the bottom lithium battery pack 27 inside the feeding bin 26, so that the bottom lithium battery pack 27 moves along the surface of the fixed platform 25. When the lithium battery pack 27 moves to the docking groove 30, it will fall into and get stuck in the inner wall of the docking groove 30. At this time, it is exactly above the battery casing 3 at the encapsulation position, and moves the subsequent encapsulation components to achieve encapsulation.

[0039] like Figure 8 As shown, the encapsulation assembly includes a receiving plate 31, which is fixedly connected to one side of the unloading hopper 2. A telescopic rod 32 is fixedly connected to the top of the receiving plate 31, and an electric clamp 33 is fixedly connected to one end of the telescopic rod 32. The bottom of the electric clamp 33 is connected to the cap end of the battery cover plate 34.

[0040] During operation: The cap on the top of the battery cover 34 can be assembled with the electric clamp 33. When the telescopic rod 32 extends, it will replace the battery cover 34 to descend and squeeze the lithium battery pack 27, which has been inserted into the docking groove 30, to move down. The lithium battery pack 27 can be pushed into the inside of the battery casing 3 first. Then, the battery cover 34 covers the top of the battery casing 3. The electric clamp 33 cancels the docking assembly of the battery cover 34. The battery cover 34 completes the sealing of the top of the battery casing 3, thereby realizing the entire encapsulation process.

[0041] like Figure 6 As shown, trapezoidal lifting blocks 35 are symmetrically fixedly connected to the top of the push plate 4.

[0042] During operation: Due to the presence of the top cap of the battery cover plate 34, the overall height of the battery casing 3 will increase after the encapsulation is completed. At this time, when the material is unloaded along the surface of the encapsulation stage 1, it cannot pass smoothly through the interior of the unloading chamber 2. However, through the trapezoidal lifting block 35, when the push plate 4 enters the interior of the unloading chamber 2 to support the remaining battery casing 3, it will simultaneously squeeze the remaining battery casing 3 upwards a certain distance, so that the encapsulated battery casing 3 can pass smoothly through the interior of the unloading chamber 2 without being affected by the remaining battery casing 3. Moreover, when passing through, the remaining battery casing 3 can also press down the cap of the battery cover plate 34 to further improve the tightness of the encapsulation.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
