Description

Technical Field

[0001] This utility model relates to the field of adsorption flaring devices, and more particularly to an adsorption flaring device for soft-pack lithium-ion batteries. Background Technology

[0002] Soft-pack lithium-ion batteries are lithium battery structures that use aluminum-plastic film as the outer packaging material. They are widely used in consumer electronics, power batteries, and energy storage systems. To achieve the encapsulation and protection of the internal cells, soft-pack lithium-ion batteries typically use aluminum-plastic composite film as the encapsulation carrier. This material has good mechanical strength and barrier properties, which can effectively prevent moisture penetration and electrolyte leakage. During the battery encapsulation process, the cells need to be placed in the aluminum-plastic film bag and sealed through a heat-sealing process. Before this, the opening end of the aluminum-plastic film bag must be flared to facilitate subsequent electrolyte injection and encapsulation operations.

[0003] However, in the existing technology, the flaring operation of aluminum-plastic film bags is mostly carried out by mechanical clamping, which can easily lead to deformation or tearing of the aluminum-plastic film bags. In addition, because the aluminum-plastic film material has a certain degree of resilience and flexibility, the opening is prone to shrinkage or collapse after flaring, making it difficult to maintain a stable shape. This can cause misalignment or wrinkles during subsequent liquid injection and heat sealing, thereby increasing the risk of leak sealing and poor welding, and seriously affecting the heat sealing quality of lithium batteries.

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

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.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 4As shown in the figure, this utility model embodiment provides a soft-pack lithium-ion battery adsorption and flaring device, including a rotary drive mechanism 1, a rotary disk 2, an upper adsorption mechanism 3, a lower adsorption mechanism 4, a hot air shaping component 5, and a material handling mechanism 6. The rotary drive mechanism 1 is connected to the bottom of the rotary disk 2, and the rotary drive mechanism 1 is used to drive the rotary disk 2 to rotate horizontally. The rotary disk 2 has four positioning slots 20 along its circumference. The positioning slots 20 are used to place aluminum-plastic film bags containing battery cells. The positioning slots 20 include a first slot 201 and a second slot 202. The first slot 201 is used to fix the battery cells in the aluminum-plastic film bag. The second slot 202 is located at the opening of the aluminum-plastic film bag. The upper adsorption mechanism 3 is located above the second slot 202, and the lower adsorption mechanism 4 is located at the second slot 202. Below 02, the upper adsorption mechanism 3 and the lower adsorption mechanism 4 are used to adsorb the surface of the aluminum-plastic film bag and move in the opposite direction to enlarge the opening of the aluminum-plastic film bag; the rotary drive mechanism 1 can drive the rotary disk 2 to rotate intermittently in the horizontal direction, thereby realizing the cyclic positioning operation of multiple stations. In each positioning slot 20, a first slot 201 is set to fix the battery inside the aluminum-plastic film bag, so that it maintains a stable position during the flaring operation and avoids movement or tilting. At the same time, the opening of the aluminum-plastic film bag is placed at the second slot 202 to expose the opening area of ​​the aluminum-plastic film bag. When the rotary disk 2 rotates to the flaring station, the upper adsorption mechanism 3 and the lower adsorption mechanism 4 located above and below the second slot 202 respectively adhere to and adsorb the upper and lower opening surfaces of the aluminum-plastic film bag, and simultaneously stretch in the opposite direction, thereby causing the opening of the aluminum-plastic film bag to gradually open, thereby realizing the flaring operation.

[0033] The hot air shaping component 5 is located on the side of the upper adsorption mechanism 3. The hot air shaping component 5 is used to blow hot air outward, and the air outlet of the hot air shaping component 5 is set towards the opening of the aluminum-plastic film bag. After the flaring operation of the opening of the aluminum-plastic film bag is completed, the hot air shaping component 5 is activated to blow hot air from the side to the opening area, so that the film material is temporarily shaped under heat, thereby solidifying the opened bag opening, effectively avoiding the collapse or wrinkling of the aluminum-plastic film bag due to natural rebound, and improving the encapsulation effect of the lithium battery.

[0034] The material handling mechanism 6 is located on the side of the rotating disk 2. The material handling mechanism 6 is used to pick up the flared aluminum-plastic film bag from the positioning slot 20.

[0035] like Figure 1 As shown, it further includes a fixing frame 11, which is located on the side of the rotating disk 2. The material picking mechanism 6, the upper adsorption mechanism 3 and the lower adsorption mechanism 4 are all located on the fixing frame 11.

[0036] like Figure 3As shown, the upper adsorption mechanism 3 and the lower adsorption mechanism 4 have the same structure, both including a connecting arm 31, a first cylinder 32, a first mounting plate 33, and a first suction nozzle 34. The connecting arm 31 is located on the side of the fixing frame 11, and the first cylinder 32 is located on the connecting arm 31, with the movable end of the first cylinder 32 facing the second slot 202 and connected to the first mounting plate 33. The first mounting plate 33 has a first waist-shaped groove 330, and the first suction nozzle 34 is detachably mounted on the first waist-shaped groove 330. The first suction nozzle 34 is used to adsorb onto the opening surface of the aluminum-plastic film bag. The first cylinder 32 can drive the first suction nozzle 34 to pull the opening area of ​​the aluminum-plastic film bag up and down, thereby realizing the flaring operation. Setting the first suction nozzle 34 in the first waist-shaped groove 330 makes it easy to adjust the installation position of the first suction nozzle 34, thereby adapting to aluminum-plastic film bags of different sizes.

[0037] like Figure 4 As shown, the hot air shaping assembly 5 further includes a mounting bracket 51, a rotary cylinder 52, a clamping frame 53, and a hot air blower 54. The mounting bracket 51 is located on the side of the connecting arm 31, and the rotary cylinder 52 is located on the mounting bracket 51. The movable end of the rotary cylinder 52 is connected to the clamping frame 53. The clamping frame 53 is used to fix and clamp the hot air blower 54. The air outlet of the hot air blower 54 is provided with a nozzle 541. The nozzle 541 has a flat structure and is used to guide and deliver hot air onto the aluminum-plastic film bag. After the flaring action is completed, the rotary cylinder 52 is activated, driving the clamping frame 53 to rotate at a set angle and positioning the hot air blower 54 at a specific blowing angle. The hot air blower 54 has a flat nozzle 541 at its outlet, which can distribute the hot air in a sheet-like manner, forming a uniform and wide blowing surface to cover the entire opening area of ​​the aluminum-plastic film bag. Thus, under the action of hot air, the opening of the aluminum-plastic film bag is temporarily kept in a fixed and expanded state, effectively suppressing the collapse or warping caused by material rebound.

[0038] like Figure 1 and Figure 3As shown, the material handling mechanism 6 further includes a linear motion module 61, a moving plate 62, a second cylinder 63, a second mounting plate 64, and a second suction nozzle 65. The linear motion module 61 is mounted on the fixed frame 11, and the movable end of the linear motion module 61 is connected to the moving plate 62. The second cylinder 63 is mounted on the moving plate 62, with its movable end facing downwards, and is connected to the second mounting plate 64. The second mounting plate 64 is provided with a second waist-shaped groove 640, and the second suction nozzle 65 is provided on the second waist-shaped groove 640. The second suction nozzle 65 is used to adsorb the surface of the aluminum-plastic film bag above the first slot 201. When the flared film bag rotates to the material handling station, the linear motion module 61 moves the moving plate 62 to directly above the positioning slot 20. Then, the second cylinder 63 activates, driving the second mounting plate 64 closer to the film bag, allowing the second suction nozzle 65 to precisely adhere to the aluminum-plastic film bag above the first slot 201, thus avoiding interference with the shaped opening area. After the second suction nozzle 65 completes its adsorption, the second cylinder 63 retracts, causing the aluminum-plastic film bag to rise as a whole. The linear motion module 61 then smoothly moves it out of its original position for subsequent processing. In this embodiment, there are two second suction nozzles 65, which effectively improves the adsorption stability of the aluminum-plastic film bag.

[0039] Furthermore, the rotary drive mechanism 1 is a cam divider, which is connected to the bottom of the rotary disk 2. This allows the rotary disk 2 to rotate intermittently in the horizontal direction at a set angle, stopping precisely at a work station each time. This ensures that multiple positioning slots 20 can sequentially and stably enter the flaring, shaping, and material handling functional areas.

[0040] 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.
