Description

Technical Field

[0001] The present invention belongs to the field of lithium battery production, and particularly relates to an edge sealing and coating device for the production of lithium battery packs for new energy vehicles. Background Art

[0002] The lithium batteries used in new energy vehicles are one of the most important components in current electric vehicle (EV) technology. These batteries power the vehicle, and their performance, cost, and safety play a crucial role in the popularization of electric vehicles.

[0003] The safety and reliability of lithium batteries are of utmost importance. During the production process of lithium batteries, the encapsulation link of the battery pack is a key step to ensure its stable performance and safety. In the current encapsulation method of the battery pack, first, a blue film (protective film) needs to be wrapped around the outer surface of the battery pack, and then a scraper is used to scrape the blue film (protective film) attached to the surface of the battery pack flat. Although this method can complete the coating work of the battery pack, it is inefficient and has a large working intensity, and is not suitable for large-scale production.

[0004] Moreover, when dealing with the edges of the battery pack using the traditional encapsulation method, due to the limitations of manual operation, problems such as uneven wrapping of the blue film (protective film) and insecure edge sealing are likely to occur. This not only affects the appearance quality of the battery pack but also may pose potential risks to the performance and safety of the battery. Therefore, developing an efficient, precise, and fully automated edge sealing and coating device for lithium battery packs has become an urgent need in the industry. Summary of the Invention

Detailed implementation manners

[0031] References to embodiments in this text mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] Embodiment: An edge sealing and coating device for the production of new energy vehicle lithium battery packs, as Figures 1 - 13As shown in the figure, it includes a conveying table 1, a blue film pulling-down component 2, a flattening component 3, a position-adjusting component 4, a pressing-edge and cutting component 5, a lifting edge-sealing component 6, a material-blocking component 7 and a transmission component 8. Above the right part of the conveying table 1, there is a blue film pulling-down component 2 installed. Inside the lower part of the blue film pulling-down component 2, there is a flattening component 3 installed. On the conveying table 1 on the right side of the blue film pulling-down component 2, there is a position-adjusting component 4 installed. On the conveying table 1 on the left side of the blue film pulling-down component 2, there is a pressing-edge and cutting component 5 installed. On the conveying table 1 on the left side of the pressing-edge and cutting component 5, there is a lifting edge-sealing component 6 installed. On the left sides of both the lifting edge-sealing component 6 and the pressing-edge and cutting component 5, there is a material-blocking component 7 set. Between the flattening component 3, the position-adjusting component 4 and the lifting edge-sealing component 6, there is a transmission component 8 connected. When this device is needed to perform edge-sealing and wrapping of the battery pack, first place the battery pack to be edge-sealed and wrapped on the right side of the equipment. The position-adjusting component 4 adjusts the position of the battery. When the battery pack is conveyed to the position of the blue film pulling-down component 2 through the conveying table 1, the blue film pulling-down component 2 wraps the blue film on the battery pack. After the battery pack is wrapped with the blue film, the conveying table 1 conveys the battery pack wrapped with the blue film to the lower part of the flattening component 3, so that the blue film wrapped on the battery pack is flattened. Subsequently, the battery pack is conveyed to the position of the pressing-edge and cutting component 5. The pressing-edge and cutting component 5 cuts the connected blue film, and at the same time, the pressing-edge and cutting component 5 presses the edge of the blue film on the battery pack. Subsequently, the battery pack is conveyed to the lifting edge-sealing component 6. The lifting edge-sealing component 6 levels the edge of the battery pack to prevent the blue film from warping. When the battery pack moves for wrapping, the material-blocking component 7 accurately controls the position of the battery pack, so that the battery pack can be wrapped at an accurate position. After the battery pack is wrapped, the battery pack is sent out from the left side of the conveying table 1, and at the same time, the blue film is pulled down again through the blue film pulling-down component 2 for the next battery pack to be wrapped.

On the left side of the mounting table 104, the slide table cylinder III 701 with the telescopic end facing downwards is fixedly connected by bolts. The telescopic end of the slide table cylinder III 701 is fixedly connected with the stopper 702 by bolts. In the middle of the left side of the left track III 601, the slide table cylinder III 701 with the telescopic end facing upwards is also fixedly connected by bolts. The telescopic end of the slide table cylinder III 701 here is also connected with the stopper 702.

[0040] As Figure 13As shown, the transmission assembly 8 includes a transmission flat belt pulley set I 801, a bidirectional lead screw II 802, and a transmission flat belt pulley set II 803. The left and right parts of the frame 101 are both rotatably connected with a bidirectional lead screw II 802 parallel to the transmission roller 102 through bearing seats. A transmission flat belt pulley set II 803 is connected between the rear ends of the bidirectional lead screws II 802, and a transmission flat belt pulley set I 801 is connected between the rear end of the bidirectional lead screw II 802 on the right side and the rear end of the bidirectional lead screw I 402.

[0041] When wrapping the battery pack, the battery pack is placed on the transmission roller 102 on the left side of the push plate 107. According to the width of the battery pack, control the motor II 401 to rotate forward, drive the bidirectional lead screw I 402 to rotate forward, and then drive the L-shaped plates 403 to move closer to each other. The L-shaped plates 403 drive the buffer rods 404 and the lateral clamping plates 405 to move closer to each other, so that the battery pack is pushed to the central position. Then control the motor II 401 to stop working. Then control the pushing cylinder 103 to extend, drive the push plate 107 to move to the left, and then drive the battery pack to move to the left. At the same time, the motor I 204 rotates forward, drives the unidirectional lead screw I 205 to rotate forward, and then drives the square clamping plate 203 and the concave clamping plate 2031 to move downward, and then drives the blue film clamped between the square clamping plate 203 and the concave clamping plate 2031 to be pulled downward, so that the blue film blocks the left side of the battery pack. When the battery pack passes through the blue film, the blue film is wrapped around the outside of the battery pack. The battery pack continues to move to the left for other wrapping operations. When the blue film is cut by the edge pressing and cutting assembly 5, control the slide cylinder I 2032 to extend, drive the concave clamping plate 2031 away from the square clamping plate 203. At this time, control the motor I 204 to reverse, drive the square clamping plate 203 and the concave clamping plate 2031 to move upward. At this time, the blue film is again between the square clamping plate 203 and the concave clamping plate 2031. Then control the slide cylinder I 2032 to shorten, drive the concave clamping plate 2031 to reset towards the square clamping plate 203, and clamp the blue film. Then control the slide cylinder I 2032 to stop working. At the same time, control the motor I 204 to rotate forward again, drive the blue film to be pulled downward, in preparation for the next wrapping of the battery pack. Repeat this process until the battery pack is completely wrapped, and then control the motor I 204 and the slide cylinder I 2032 to stop working.

[0042] According to the thickness of the battery pack, control the extension or shortening of the sliding table cylinder II 308, drive the vertical pressing cylinder 305 to move upward or downward, so that the vertical pressing cylinder 305 can just press on the upper surface of the battery pack. After the height of the vertical pressing cylinder 305 is adjusted, control the sliding table cylinder II 308 to stop working to maintain the height of the vertical pressing cylinder 305. At the same time, when the bidirectional lead screw I 402 rotates, drive the bidirectional lead screw II 802 on the right side to rotate through the transmission flat belt pulley set I 801, and then drive the lateral pressing plates 302 to approach each other, drive the lateral pressing cylinders 306 to approach inward, and the lateral pressing cylinders 306 just press on the front and rear sides of the battery pack, so that the blue film attached to the surface of the battery pack can be flattened by the lateral pressing cylinders 306, the vertical pressing cylinder 305 and the lower transmission roller 102.

[0043] When the battery pack moves below the positioning and adjusting assembly 4, control the extension of the lifting cylinder I 501 to drive the upper L-shaped pressing plate 502 to move downward, thereby driving the rack I 507 to move downward. Through the counterclockwise rotation of the gear 510, the rack II 509 moves upward, driving the lower L-shaped pressing plate 508 to move upward. At this time, the upper L-shaped pressing plate 502 moves downward and the lower L-shaped pressing plate 508 moves upward. After the lower L-shaped pressing plate 508 presses on the upper and lower edges of the right side of the battery pack, control the lifting cylinder I 501 to stop working. Subsequently, control the motor III 504 to rotate, drive the unidirectional lead screw II 505 to rotate, and then drive the cutting blade 506 to move backward to cut off the connected blue film. At the same time, the cushion plate 108 on the push plate 107 can prevent the cutting blade 506 from damaging the push plate 107. After the blue film is cut off, control the motor III 504 to reverse, drive the unidirectional lead screw II 505 to reverse, so that the cutting blade 506 returns to its original position, and then control the motor III 504 to stop working. Subsequently, control the lifting cylinder I 501 to shorten and reset, drive the upper L-shaped pressing plate 502 to move upward and reset, and the lower L-shaped pressing plate 508 to move downward and reset. Then the battery pack continues to move to the left to perform the remaining wrapping work.

[0044] When the battery module moves below the lifting edge-sealing assembly 6, since the driving flat belt pulley set II 803 drives the double-threaded screw rod II 802 on the left side to rotate, at this time, the connecting plate 613 and the devices thereon are adjusted to appropriate positions. Subsequently, the lifting cylinder II 604 is controlled to extend downward, driving the lifting frame 607 and the components thereon to move downward, so that the upper pressing cylinder 608 moves downward. When the upper pressing cylinder 608 moves downward to contact the front and rear edges of the upper surface of the battery pack, the blue film at the edge of the battery pack is bent downward. At the same time, the pressing angle wheels 619 are located on the left and right sides of the battery pack, pressing the blue films on the left and right sides on the surface of the battery pack. When the lifting frame 607 moves downward, it drives the upper wedge-shaped block 615 to move downward. When the upper wedge-shaped block 615 moves downward to contact the follower wheel 612, it pushes the follower wheel 612 to move inward. When the follower wheel 612 moves to the innermost end of the upper wedge-shaped block 615, under the action of the hook spring 614, the follower wheel 612 is stuck above the upper wedge-shaped block 615. At this time, the lifting cylinder II 604 is controlled to shorten and reset, driving the lifting frame 607 and the upper wedge-shaped block 615 to move upward. At this time, under the action of the upper wedge-shaped block 615, the L-shaped frame 609 and the lower pressing cylinder 610 are pulled to move upward, pressing the blue films at the front and rear edges of the lower surface of the battery pack on the surface of the battery pack. When the follower wheel 612 moves upward to contact the lower wedge-shaped block 616, under the action of the lower wedge-shaped block 616, it drives the follower wheel 612 to move inward. When the follower wheel 612 moves to the inner end of the upper wedge-shaped block 615, under the action of the hook spring 614, the L-shaped frame 609 and the devices thereon move downward to reset. At the same time, the height of the insertion rod 617 can also be changed to adjust the pulling force of the hook spring 614. When the insertion rod 617 is inserted upward, the pulling force of the hook spring 614 on the follower wheel 612 becomes smaller. When the insertion rod 617 is pulled downward, the pulling force of the hook spring 614 on the follower wheel 612 becomes larger.

[0045] When the battery pack moves below the edge-pressing and cutting assembly 5, the sliding table cylinder III 701 on the mounting table 104 is controlled to extend, driving the stop block 702 to move downward to block the front side of the battery pack, so that the battery pack cannot move to the left. Then, the edge-pressing and cutting work can be started. After the edge-pressing and cutting work is completed, the sliding table cylinder III 701 on the mounting table 104 is controlled to reset, driving the stop block 702 to move upward to reset. When the battery pack moves to the position of the lifting edge-sealing assembly 6, the sliding table cylinder III 701 on the track III 601 is controlled to extend, driving the stop block 702 to move upward to limit the battery pack. After the battery pack completes the lifting edge-sealing work, the sliding table cylinder III 701 is controlled to reset to drive the stop block 702 to reset.
