Firstly, it offers excellent barrier properties, effectively blocking the intrusion of oxygen, moisture, and light, thereby protecting the contents within. For example, in lithium-ion batteries, aluminum-plastic film prevents the battery's interior from interacting with the external environment, ensuring its performance and safety.

[0003] When processing the aluminum-plastic film used for the arc-shaped lithium battery, it is necessary to use a forming device to die-cut the strip-shaped aluminum-plastic film to obtain the aluminum-plastic film of suitable shape and size. However, when the existing forming device performs die-cutting on the aluminum-plastic film, it is difficult to ensure the flatness of the aluminum-plastic film. At the same time, the formed aluminum-plastic film is not conducive to being separated from and collected by the device. Therefore, in view of the above technical defects of the prior art, a arc-shaped lithium battery aluminum-plastic film forming mold is proposed to solve the above technical problems.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments:

[0023] Example 1: Please refer to Figure 1-7 , a curved lithium battery aluminum-plastic film forming mold, including a processing table 1, a support frame 2 is fixed on the processing table 1, a vertical cylinder 3 is fixed on the support frame 2, an aluminum-plastic film 5 is installed on the processing table 1, and a die-cutting tool 4 vertically corresponding to the aluminum-plastic film 5 is fixed at the telescopic end of the vertical cylinder 3. A support plate 13 is vertically slidably installed on the processing table 1 through an elastic support assembly, a guide frame 9 is slidably installed on the processing table 1, and a transmission frame 7 is hinged between the guide frame 9 and the die-cutting tool 4, a sleeve block 14 is fixed on the processing table 1, and a connecting spring 15 is fixed between the sleeve block 14 and the guide frame 9, a leveling roller 6 that contacts the upper surface of the aluminum-plastic film 5 is rotatably installed on the guide frame 9, and a one-way locking assembly for unidirectionally locking the leveling roller 6 is installed on the guide frame 9, a collecting trough 8 is fixed at the bottom of the processing table 1, and a pushing assembly arranged opposite to the collecting trough 8 is installed at the bottom of the processing table 1.

[0024] As an improved solution of the present utility model: the one-way locking assembly includes a check wheel 16 fixed coaxially with the leveling roller 6, and a plurality of wedge grooves 20 are evenly arranged on the check wheel 16 in a circumferential direction. A check wedge block 17 that is plugged into and adapted to the wedge groove 20 is slidably installed on the guide frame 9, and a limiting plate 19 is fixed on the guide frame 9, and a push spring 18 is fixed between the limiting plate 19 and the check wedge block 17.

[0025] When the device is used to process the aluminum-plastic film 5 , the aluminum-plastic film 5 is placed on the processing table 1 , and the die-cutting tool 4 is driven downward by the vertical cylinder 3 to die-cut the aluminum-plastic film 5 .

[0026] During the downward movement of the die-cutting tool 4, the die-cutting tool 4 drives the smoothing roller 6 to move to both sides under the guidance of the guide frame 9 through the transmission frame 7, so that the smoothing roller 6 smoothes the aluminum-plastic film 5 in the processing and forming area from the middle to both sides, effectively improving the forming processing quality of the aluminum-plastic film 5.

[0027] In the process of the smoothing roller 6 moving toward both sides, the non-return wheel 16 is engaged with the non-return wedge 17 and cannot rotate, thereby realizing the lateral translation of the smoothing roller 6 and smoothing the aluminum-plastic film 5, which greatly improves the smoothing effect of the aluminum-plastic film 5. When the die-cutting tool 4 moves up and resets, the smoothing roller 6 moves from both sides toward the middle, and the smoothing roller 6 and the aluminum-plastic film 5 roll relative to each other, and will not pull the aluminum-plastic film 5. The reciprocating movement of the smoothing roller 6 realizes a unidirectional smoothing effect on the aluminum-plastic film 5, which greatly improves the forming quality of the aluminum-plastic film 5.

[0028] Example 2: Please refer to Figure 1-7 In addition to Example 1, the support plate 13 of this device is provided with a circular groove 23 vertically corresponding to the die-cutting tool 4. A pressure plate 21 is vertically slidably mounted on the bottom of the die-cutting tool 4, and a spring 22 is fixed between the pressure plate 21 and the die-cutting tool 4. The elastic support assembly includes several hangers 24 fixed to the bottom of the processing table 1. A slide column 26 fixed to the support plate 13 is vertically slidably mounted on the hangers 24. The slide column 26 is sleeved with a spring coil 25, whose ends are respectively fixed to the support plate 13 and the hangers 24. A friction block 27 is fixed to the bottom of the hanger 24, and the friction block 27 frictionally abuts against the surface of the slide column 26. The pusher assembly includes a horizontal cylinder 10 fixed to the bottom of the processing table 1. A pusher frame 12 slidably connected to the processing table 1 is fixed to the telescopic end of the horizontal cylinder 10. A wedge-shaped pusher plate 11 is slidably mounted on the bottom of the pusher frame 12, and a vertical spring 28 is fixed vertically between the wedge-shaped pusher plate 11 and the pusher frame 12.

[0029] The aluminum-plastic film 5 falls on the support plate 13, and is driven by the horizontal cylinder 10 to push the push rack 12 and the wedge-shaped push plate 11 to push the aluminum-plastic film 5 into the collection tank 8 for collection.

[0030] To sum up, the die-cutting tool 4 provided in the present invention moves vertically downward and performs die-cutting processing on the aluminum-plastic film 5, and the smoothing roller 6 provided can smooth the aluminum-plastic film 5 during the downward movement of the die-cutting tool 4, thereby greatly improving the processing quality of the aluminum-plastic film 5. After the die-cutting processing of the aluminum-plastic film 5, the pressure plate 21 provided can push the aluminum-plastic film 5 to achieve rapid discharge. With the help of the pushing component, the formed aluminum-plastic film 5 can be pushed to achieve centralized collection and processing of the aluminum-plastic film 5, thereby greatly improving the forming processing efficiency of the aluminum-plastic film 5.
