Description

Technical Field

[0001] This utility model relates to the field of battery packaging equipment, and in particular to a fully automated polymer battery packaging equipment. Background Technology

[0002] Polymer battery packaging equipment is used to place the assembled battery cells into an aluminum-plastic film casing and seal the battery cells by heating and pressing the edges of the aluminum film. It is a piece of equipment in the mass production line of polymer lithium batteries.

[0003] In existing technologies, polymer battery encapsulation typically involves heat-sealing the edges of an aluminum film using upper and lower heat-sealing plates. During this process, the battery cell inside the aluminum film is prone to shifting, leading to warping, bulging, and other deformations that affect the encapsulation effect and reliability. Furthermore, excessive heat-sealing pressure can cause damage to the aluminum film due to over-compression, while insufficient heat-sealing pressure can result in incomplete sealing, thus affecting the product's encapsulation yield and making it difficult to maintain a stable encapsulation effect for polymer batteries.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fully automatic polymer battery packaging equipment with good packaging effect and improved packaging efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution: a fully automatic polymer battery packaging device, comprising an upper heat sealing plate, a lower heat sealing plate, an upper heating seat, a lower heating seat, a lifting mechanism, a pressing mechanism, and a holding mechanism;

[0007] The upper heat-sealing plate is located above the lower heat-sealing plate, and a receiving chamber for accommodating the polymer battery is formed between the upper heat-sealing plate and the lower heat-sealing plate. The bottom of the upper heat-sealing plate abuts against the upper surface edge of the aluminum film of the polymer battery, and the top of the lower heat-sealing plate abuts against the lower surface edge of the aluminum film of the polymer battery. The upper heat-sealing plate and the lower heat-sealing plate are used to heat-seal the edge of the aluminum film of the polymer battery under heated conditions.

[0008] The upper heating seat is located on top of the upper heat-sealing plate. The upper heating seat is provided with an upper heating tube inside. The upper heating tube is used to heat the upper heat-sealing plate. The movable end of the lower pressing mechanism is set downward and connected to the upper heating seat. The lower pressing mechanism is used to drive the upper heat-sealing plate to press against the upper surface of the aluminum film of the polymer battery.

[0009] The lower heating seat is located at the bottom of the lower heat-sealing plate. The lower heating seat is provided with a lower heating tube inside. The lower heating tube is used to heat the lower heat-sealing plate. The movable end of the lifting mechanism is arranged upward and connected to the lower heating seat. The lifting mechanism is used to drive the lower heat-sealing plate to press against the lower surface of the aluminum film of the polymer battery.

[0010] The pressing mechanism includes a lower pressing plate and a swing arm assembly. The lower pressing plate is located in the accommodating cavity above the polymer battery. The swing arm assembly is connected to the lower pressing plate and is used to drive the lower pressing plate to press against the upper surface of the polymer battery.

[0011] Using the above technical solution, in the fully automatic polymer battery packaging equipment, the swing arm assembly includes a fixed base, a swing arm, and a swing cylinder. The swing arm and the fixed base are oscillatingly connected by a pin. One end of the swing arm is connected to the lower pressure plate, and the other end is connected to the movable end of the swing cylinder. The swing cylinder is used to drive the swing arm to swing around the pin so that the lower pressure plate can perform a pressing or resetting action on the upper surface of the polymer battery.

[0012] Using the above technical solution, in the fully automatic polymer battery packaging equipment, the pressing mechanism includes a fixed plate, a lifting cylinder, a lifting seat, and a guide rail assembly;

[0013] The lifting cylinder is mounted on the fixed plate with its movable end facing downward and connected to the lifting seat. The lifting cylinder is used to drive the lifting seat to move up and down in the vertical direction. The guide rail assembly is located on both sides of the lifting seat and is used to guide and limit the up and down movement of the lifting seat.

[0014] Using the above technical solution, in the fully automated polymer battery packaging equipment, the lifting mechanism and the pressing mechanism have the same structure.

[0015] The fully automated polymer battery packaging equipment described above also includes an upper connecting plate and a lower connecting plate. The pressing mechanism is connected to the upper heating seat through the upper connecting plate, and the lifting mechanism is connected to the lower heating seat through the lower connecting plate.

[0016] The fully automated polymer battery packaging equipment described above further includes an upper limit rod and a lower limit rod. The upper limit rod is disposed on the upper connecting plate, and the lower limit rod is disposed on the lower connecting plate. The upper limit rod is located directly above the lower limit rod. The upper limit rod is used to abut against the lower limit rod when the heat sealing stroke reaches a predetermined position.

[0017] Using the above technical solution, in the fully automated polymer battery packaging equipment, the top of the upper limit rod is threadedly connected to the upper connecting plate, and the bottom of the lower limit rod is threadedly connected to the lower connecting plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention uses heating tubes in the upper and lower heating seats to uniformly heat the upper and lower heat-sealing plates respectively. The pressing mechanism drives the upper heat-sealing plate downward to press against the upper surface edge of the aluminum film, and the lifting mechanism drives the lower heat-sealing plate upward to press against the lower surface edge of the aluminum film, thereby achieving synchronous pressing of the upper and lower surfaces of the aluminum film and applying pressure evenly, thus improving the heat-sealing effect and sealing performance. The swing arm assembly in the holding mechanism drives the lower pressing plate to press against the upper surface of the polymer battery. In this way, the aluminum film is prevented from affecting the battery sealing effect due to cell misalignment during the sealing process, and warping or bulging is also avoided, effectively improving the heat-sealing effect.

Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 3 As shown, this utility model embodiment provides a fully automatic polymer battery packaging device, including an upper heat-sealing plate 1, a lower heat-sealing plate 2, an upper heating seat 3, a lower heating seat 4, a lifting mechanism 5, a pressing mechanism 6, and a holding mechanism 7. The upper heat-sealing plate 1 is located above the lower heat-sealing plate 2, and a receiving chamber for accommodating the polymer battery is formed between the upper heat-sealing plate 1 and the lower heat-sealing plate 2. The bottom of the upper heat-sealing plate 1 abuts against the upper edge of the aluminum film of the polymer battery, and the top of the lower heat-sealing plate 2 abuts against the lower edge of the aluminum film of the polymer battery. The upper heat-sealing plate 1 and the lower heat-sealing plate 2 are used to heat-seal the edge of the aluminum film of the polymer battery under heat. Since the aluminum film of the polymer battery is supported by a soft-pack material, the heating of the upper heat-sealing plate 1 and the lower heat-sealing plate 2 can cause the aluminum film to form a seal under pressure after being heated, thereby improving the packaging quality and the sealing performance of the battery.

[0029] The upper heating seat 3 is located at the top of the upper heat-sealing plate 1. An upper heating tube 31 is installed inside the upper heating seat 3, and the upper heating tube 31 is used to heat the upper heat-sealing plate 1. The movable end of the lower pressing mechanism 6 is downward-facing and connected to the upper heating seat 3. The lower pressing mechanism 6 is used to drive the upper heat-sealing plate 1 to press against the upper surface of the aluminum film of the polymer battery. The lower heating seat 4 is located at the bottom of the lower heat-sealing plate 2. A lower heating tube 41 is installed inside the lower heating seat 4, and the lower heating tube 41 is used to heat the lower heat-sealing plate 2. The movable end of the lifting mechanism 5 is upward-facing and connected to the lower heating seat 4. The lifting mechanism 5 is used to drive the lower heating tube 41 to press against the upper surface of the polymer battery. The sealing plate 2 presses against the lower surface of the aluminum film of the polymer battery; the upper heating tube 31 raises the temperature of the upper heat sealing plate 1 by heating the upper heating seat 3, and the lower heating tube 41 raises the temperature of the lower heat sealing plate 2 by heating the lower heating seat 4. After heating, the upper heat sealing plate 1 and the lower heat sealing plate 2 will contact the upper and lower surface edges of the battery aluminum film respectively. The aluminum film is heated to a suitable heat sealing temperature for encapsulation. At the same time, the pressing mechanism 6 can drive the upper heat sealing plate 1 to press down onto the upper surface of the aluminum film, while the lifting mechanism 5 can drive the lower heat sealing plate 2 to press up onto the lower surface of the aluminum film. In this way, the upper and lower surfaces of the aluminum film can be pressed together synchronously, improving the heat sealing effect and the sealing performance of the battery.

[0030] The pressing mechanism 7 includes a lower pressing plate 71 and a swing arm assembly 72. The lower pressing plate 71 is located in the accommodating cavity above the polymer battery. The swing arm assembly 72 is connected to the lower pressing plate 71 and is used to drive the lower pressing plate 71 to press against the upper surface of the polymer battery. In this way, it can be ensured that the aluminum film will not affect the packaging quality stability of the polymer battery due to cell displacement during the packaging process, while avoiding warping or bulging, thereby improving the heat sealing effect and the battery's sealing performance.

[0031] like Figure 1 and Figure 3 As shown, the swing arm assembly 72 further includes a fixed base 721, a swing arm 722, and a swing cylinder 723. The swing arm 722 is oscillatingly connected to the fixed base 721 via a pin. One end of the swing arm 722 is connected to the lower pressure plate 71, and the other end is connected to the movable end of the swing cylinder 723. The swing cylinder 723 drives the swing arm 722 to swing around the pin so that the lower pressure plate 71 can perform a pressing or resetting action on the upper surface of the polymer battery. When the swing cylinder 723 drives the swing arm 722, the swing arm 722 can drive the lower pressure plate 71 to press the upper surface of the polymer battery, ensuring close contact between the aluminum film and the battery surface, and avoiding cell displacement or aluminum film bulging during the heat sealing process.

[0032] like Figure 1 and Figure 2As shown, the pressing mechanism 6 further includes a fixed plate 61, a lifting cylinder 62, a lifting seat 63, and a guide rail assembly 64. The lifting cylinder 62 is mounted on the fixed plate 61, with its movable end facing downwards, and is connected to the lifting seat 63. The lifting cylinder 62 drives the lifting seat 63 to move up and down vertically. The guide rail assembly 64 is located on both sides of the lifting seat 63 and guides and limits the vertical movement of the lifting seat 63. When the lifting cylinder 62 moves, the upper heat-sealing plate 1 can be pressed down to a position contacting the surface of the polymer battery aluminum film through the lifting seat 63, thereby achieving heat sealing of the edge of the aluminum film. The guide rail assembly 64 is located on both sides of the lifting seat 63 and can guide and limit the vertical movement of the lifting seat 63, ensuring that the lifting seat 63 maintains stable linear movement in the vertical direction and avoiding deviation or tilting. It should be noted that in this embodiment, the lifting mechanism 5 has the same structure as the pressing mechanism 6.

[0033] like Figure 1 As shown, it further includes an upper connecting plate 81 and a lower connecting plate 82. The pressing mechanism 6 is connected to the upper heating seat 3 through the upper connecting plate 81, and the lifting mechanism 5 is connected to the lower heating seat 4 through the lower connecting plate 82.

[0034] like Figure 1 As shown, further, it also includes an upper limit rod 91 and a lower limit rod 92. The upper limit rod 91 is disposed on the upper connecting plate 81, and the lower limit rod 92 is disposed on the lower connecting plate 82, with the upper limit rod 91 located directly above the lower limit rod 92. The upper limit rod 91 is used to abut against the lower limit rod 92 when the heat sealing stroke reaches a predetermined position. When the heat sealing stroke reaches the predetermined pressing position, the upper limit rod 91 and the lower limit rod 92 come into contact with each other, thereby playing a physical limiting role. At this time, the movement of the upper heat sealing plate 1 and the lower heat sealing plate 2 stops, preventing the heat sealing plates from continuing to move and causing excessive pressing, thereby preventing the aluminum film from being excessively squeezed and damaged.

[0035] like Figure 1 and Figure 2 As shown, the top of the upper limit rod 91 is connected to the upper connecting plate 81 by a thread, and the bottom of the lower limit rod 92 is connected to the lower connecting plate 82 by a thread. In this way, the operator can adjust the height of the upper limit rod 91 and the lower limit rod 92 according to actual needs, thereby realizing the adjustment of the heat sealing stroke.

[0036] Components not described in detail in this article are existing technologies and will not be elaborated upon here.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
