Description

Technical Field

[0001] This utility model relates to the field of side sealing mechanisms, specifically a side sealing mechanism used in battery processing. Background Technology

[0002] Batteries are increasingly used in new energy vehicles and other fields, especially soft-pack batteries packaged with materials such as aluminum-plastic film. A battery side-sealing machine is a specialized piece of equipment for battery packaging. Its main function is to heat-seal the sides of the battery during the aluminum-plastic film packaging process to ensure the battery's airtightness and safety. As the outer shell material for soft-pack batteries, aluminum-plastic film requires multiple heat-sealing processes, including side sealing and top sealing, after the battery cells are installed to achieve airtight sealing. The side-sealing process requires precise heat pressing on both sides of the aluminum-plastic film to ensure sealing strength and consistency. This equipment is widely used in new energy vehicles, energy storage systems, and portable electronic devices, and is an indispensable part of the battery production process.

[0003] Publication (Announcement) No.: CN222088671U, a lithium battery top-side sealing machine is disclosed, comprising a housing, a bottom dragging assembly, and a stabilizing side-sealing mechanism; the housing has a working groove in the middle of its front side, and an instrument mounting box is located on the upper front side inside the housing; the bottom dragging assembly is located on the bottom wall of the working groove; the stabilizing side-sealing mechanism is located on the top wall of the working groove, and the bottom dragging assembly is fixedly connected to the stabilizing side-sealing mechanism; it also includes support legs, which are respectively located at the four corners of the bottom surface of the housing, and the lower end of each support leg is provided with a foot; it also includes a control panel, which is located on the upper front side of the housing, and the input end of the control panel is electrically connected to an external power source. This lithium battery top-side sealing machine can achieve clamping and positioning functions without additional clamping tools, reducing processing steps and thus improving the lithium battery packaging speed.

[0004] The applicant believes the above application has the following defects: When placing the battery, the entire insertion plate is picked up by hand and then inserted into the bottom placement slot through the slide and guide rail. When removing the battery, the entire insertion plate is picked up by hand and then inserted into the bottom placement slot through the slide and guide rail before being removed by hand. At this time, each lithium battery that has been heat-fused is removed sequentially. In a lithium battery top side sealing machine, the placement and positioning of the battery relies on manual operation. This not only increases the complexity of the operation but also easily leads to inaccurate positioning, thus affecting the accuracy of side sealing. Manual operation is prone to errors, and manual positioning results in low accuracy, leading to sealing defects after sealing. Differences in operator experience can easily introduce millimeter-level deviations, affecting the sealing alignment. Secondly, during the side sealing process, after the battery undergoes high-temperature heat sealing, its surface aluminum-plastic film becomes extremely hot, possibly even reaching a temperature that can burn the human body. In the above operation, the battery needs to be manually removed, which is not only difficult to operate but also extremely likely to cause burns. Furthermore, manual handling can damage the battery during removal, affecting its performance and lifespan. The heat-fused batteries, after processing, need to be removed manually, which can easily lead to burns. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is combined Figures 1-4 The side sealing mechanism for battery processing according to this utility model is described in detail below:

[0021] A side-sealing mechanism for battery processing includes a base 1 and a translation component, the translation component being positioned above the base 1. A support frame 11 is vertically mounted on the surface of the base 1, and an electric heating component 33 is mounted on the side of the support frame 11. A placement box 7 is positioned above the base 1. A first linear electric cylinder 2 for driving the placement box 7 to move is mounted on the surface of the base 1. A pull rod 3 is mounted at the output end of the first linear electric cylinder 2. Two first slide rails 4 are mounted on the surface of the base 1, symmetrically arranged between the two first slide rails 4. A slidable first slider 5 is mounted on the surface of each of the first slide rails 4. The first slider 5 is connected to the first... The slide rails 4 are slidably connected. The bottom of the placement box 7 is provided with a fixing plate 6, which is connected to the bottom of the first slider 5. One end of the pull rod 3 is connected to the fixing plate 6. The fixing plate 6 is provided with a second linear electric cylinder 12. The output end of the second linear electric cylinder 12 is provided with a push rod 21. The surface of the placement box 7 is provided with a circular pipe 9. When the second linear electric cylinder 12 works, it drives the push rod 21 to push out in the vertical direction of the circular pipe 9. The fixing plate 6 has the second linear electric cylinder 12 built in it. Through the cooperation of the push rod 21 with the vertical direction of the circular pipe 9, the lithium battery can be stably lifted and pushed out.

[0022] The placement box 7 has several horizontally arranged resistive heating tubes 8 inside, and adjacent resistive heating tubes 8 are symmetrically arranged. Both ends of the resistive heating tubes 8 extend to the outside of the placement box 7. The surface of the placement box 7 has several through holes 10, and the through holes 10 are connected to the circular pipe 9.

[0023] The translation component is disposed on the side of the support frame 11. The translation component includes a motor mounting base 14 disposed on the side of the support frame 11, a rotary motor 13 disposed on the support frame 11, and a movable slide plate 22. A second slide rail 24 is disposed on the side of the support frame 11, and a slidable second slider 25 is disposed on the surface of the second slide rail 24. The second slider 25 is slidably connected to the second slide rail 24. A rotatable lead screw 15 is disposed at the output end of the rotary motor 13, and a third slider 17 is sleeved on the lead screw 15. Two third slide rails 16 are disposed on the side of the support frame 11, and the third slider... The second slider 25 and the third slider 17 are slidably connected to the third slide rail 16. The rotary motor 13 is used to drive the lead screw 15 to convert the rotational motion into linear motion. The surfaces of the second slider 25 and the third slider 17 are provided with positioning plates 18. One end of the positioning plate 18 is provided with a third linear electric cylinder 19. The output end of the third linear electric cylinder 19 is provided with a push rod 20. One end of the push rod 20 is connected to the movable slide plate 22. The surface of the positioning plate 18 is provided with two fourth slide rails 23. The two fourth slide rails 23 are symmetrically arranged. The movable slide plate 22 is slidably connected to the fourth slide rails 23.

[0024] The electric heating assembly 33 includes a side plate 26 screwed onto the movable slide plate 22, a mounting plate 29 vertically disposed at the bottom of the side plate 26, and a heating element 27 disposed on the surface of the side plate 26. A pressing head 28 is disposed at the bottom of the heating element 27. Heating the pressing head 28 by the heating element 27 allows for the hot melting of the aluminum-plastic film, sealing the top of the lithium battery. A connecting plate 30 is disposed on the surface of the side plate 26, connecting the side plate 26 and the mounting plate 29. A sealing plate 31 is vertically disposed on the surface of the side plate 26, with a connecting rod 32 on its side. The bottom of the connecting rod 32 is connected to the mounting plate 29. The side plate 26 and mounting plate 29 are used to install the electric heating assembly 33, while the connecting plate 30 and sealing plate 31 enhance the overall structural strength of the electric heating assembly 33. The base 1 has several screw holes on its surface, allowing for fixing to the side sealing machine with bolts, thus improving equipment stability.

[0025] The translation component uses a rotary motor 13 to drive the lead screw 15 to rotate, converting the rotational motion into linear motion. This drives the third slider 17 to move along the third slide rail 16 and the second slider 25 to move along the second slide rail 24, causing the positioning plate 18 on the second slider 25 and the third slider 17 to move. This enables the adjustable movement of the heating component 33 in the X-axis direction. The third linear electric cylinder 19 drives the push rod 20 to move, causing the moving slide plate 22 to move along the fourth slide rail 23, enabling the adjustable movement of the heating component 33 in the Y-axis direction. The heating element 27 forms a modular structure with the mounting plate 29 through the connecting plate 30. Combined with the reinforcement design of the sealing plate 31 and the connecting rod 32, the structural stability of the heating component 33 is greatly improved.

[0026] The placement box 7 is fixed on the fixing plate 6. Multiple horizontally symmetrically distributed resistance heating tubes 8 are installed inside. These tubes heat the placement box 7. The through-hole 10 and the circular pipe 9 facilitate air circulation, preventing overheating inside the placement box 7. When the aluminum-plastic film-packaged lithium batteries are placed sequentially into the circular pipe 9, the resistance heating tubes 8 heat the placement box 7, causing the aluminum-plastic film to tightly wrap the outer surface of the lithium batteries, sealing the sides. Furthermore, the through-hole 10 on the placement box 7 dissipates excess heat, preventing overheating and localized overheating that could lead to sealing defects. Simultaneously, the rotating motor 13 drives the lead screw 15 to rotate, converting rotary motion into linear motion. This drives the third slider 17 to move along the third slide rail 16 and the second slider 25 to move along the second slide rail 24, causing the second slider... The positioning plate 18 on block 25 and the third slider 17 moves to bring the heating component 33 closer to the lithium battery on the placement box 7, and heats the pressing head 28 through the heating element 27. The resistance heating tube 8 preheats the battery side sealing area. The translation component adjusts the position of the pressing head 28 of the heating element 27 so that it presses vertically down to the battery sealing point, maintaining a preset pressure (e.g., 0.5MPa) and duration (e.g., 2s). The heating component 33 is driven by the rotating motor 13 to further press the lithium battery and seal the top surface of the lithium battery. After the hot pressing is completed, the third linear electric cylinder 19 retracts the push rod 20, and the heating component 33 resets. At this time, the push rod 21 is driven by the second linear electric cylinder 12 to push out in the vertical direction of the circular pipe 9, quickly pushing out the hot-melted lithium battery without the need for manual handling of the hot-melted battery, thus avoiding burns to the hands.

[0027] The side sealing mechanism for battery processing in this embodiment uses a first linear electric cylinder 2 to drive a pull rod 3 to move. This pull rod 3 causes the fixing plate 6, the placement box 7, and the first slider 5 to move along the first slide rail 4, ensuring precise alignment of the battery position with the heating component 33. This avoids errors from manual adjustment and improves the side sealing alignment accuracy. A second linear electric cylinder 12 drives a push rod 21 to push the battery vertically out along the circular pipe 9, allowing the side-sealed battery to be pushed out quickly, greatly improving processing efficiency. There is no need for manual handling of the fused battery, avoiding burns to the hands. At this point, the aluminum-plastic film is melted to complete the top and side sealing. No additional clamping tools are needed to clamp the lithium battery, and the clamping and positioning function can be achieved, reducing processing steps and thus increasing the lithium battery packaging speed.

[0028] In use, the base 1 is installed onto the side sealing machine using screws. The lithium batteries, packaged in aluminum-plastic film, are sequentially placed inside the circular pipe 9. The first linear electric cylinder 2 drives the pull rod 3 to move, causing the pull rod 3 to pull the fixing plate 6, the placement box 7, and the first slider 5 along the first slide rail 4, ensuring precise alignment of the battery position with the heating element 33. The rotating motor 13 drives the lead screw 15 to rotate, converting the rotational motion into linear motion, driving the third slider 17 to move along the third slide rail 16, and the second slider 25 to move along the second slide rail 24. This causes the positioning plates 18 on the second slider 25 and the third slider 17 to move, thus moving the heating element 33. The battery is precisely positioned inside the placement box 7. Once positioned, the heating component 33 is brought close to the lithium battery on the placement box 7, and the pressing head 28 is heated by the heating element 27. The side sealing area of ​​the battery is preheated by the resistance heating tube 8. The position of the pressing head 28 of the heating element 27 is adjusted by the translation component so that it is pressed vertically down to the battery sealing area. The heating component 33 is driven by the rotating motor 13 to press the lithium battery further, sealing the top surface of the lithium battery. After the hot pressing is completed, the push rod 21 is driven by the second linear electric cylinder 12 to push out in the vertical direction of the circular pipe 9, quickly pushing out the hot-melted lithium battery, thus completing the sealing of the top and side surfaces of the entire battery.

[0029] In this embodiment, the resistance heating tube 8, the first linear electric cylinder 2, the second linear electric cylinder 12, the third linear electric cylinder 19, and the heating element 27 can all be freely configured according to the actual application scenario. The operation of the resistance heating tube 8, the first linear electric cylinder 2, the second linear electric cylinder 12, the third linear electric cylinder 19, and the heating element 27 all adopt methods commonly used in the prior art.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
