Description

Technical Field

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

[0002] When manufacturing pouch batteries, after the battery cells are placed into the perforated aluminum-plastic casing, the casing needs to be sealed to create a sealed space to accommodate the battery cells.

[0003] The existing packaging device is a direct-connection one-to-one cylinder packaging structure. The two end caps of the packaging device correspond to two reciprocating cylinders respectively. The driving end of each reciprocating cylinder is connected to a corresponding end cap. The driving direction of the two reciprocating cylinders is the direction in which the two end caps point towards each other. Under the driving action of the two reciprocating cylinders, the two end caps can approach each other and squeeze each other to achieve the compression packaging of the aluminum-plastic shell.

[0004] The structure uses two reciprocating cylinders to drive a corresponding end cap, which makes the encapsulation device large in size and cannot meet the installation conditions with limited space.

[0005] Therefore, there is an urgent need to propose a packaging device and packaging equipment to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0048] like Figures 1 to 2 As shown in the figure, this embodiment provides a packaging device, mainly used for packaging the aluminum-plastic shell of a soft-pack battery. The packaging device includes a vacuum chamber 1, a sealing drive component 2, a suction gas source (not shown in the figure), and a packaging unit. The packaging unit has a relatively compact structure, which is beneficial for installing the packaging unit in installation conditions with limited space.

[0049] To facilitate understanding of the technical solution of this packaging equipment, the first direction D1, the second direction D2, and the third direction D3 are introduced as reference points to accurately and concisely describe the structure and mating relationships of the packaging equipment and its components. The first direction D1 refers to... Figure 1 The vertical direction in the middle, the second direction D2 refers to Figure 1 In the left and right directions, the third direction D3 refers to Figure 1 The front and back directions in the diagram. It should be noted that the above description of the first direction D1, the second direction D2, the third direction D3, and the relative positional relationships between the components are only examples and do not mean that the packaging equipment and its mechanism must be arranged according to the up, down, left, right, front and back directions in the illustration during actual installation and operation. As long as the relevant mechanisms and components can cooperate to achieve the required functions, they are sufficient. Examples will not be given here.

[0050] Continue as Figures 1 to 5As shown, the encapsulation device includes a support 100, an encapsulation drive mechanism 200, a hinged transmission mechanism 300, and a sealing head mechanism 400. The encapsulation drive mechanism 200 is mounted on the support 100, and its drive end is configured to move along a first direction D1. The hinged transmission mechanism 300 includes a first transmission member 310 and a second transmission member 320. The first transmission member 310 includes a first rotating part 311, a first input end 312, and a first output end 313. The first rotating part 311 is located between the first input end 312 and the first output end 313 and is hinged to the support 100 around a first axis 314. The first input end 312 is in transmission engagement with the drive end of the encapsulation drive mechanism 200. The encapsulation drive mechanism 200 drives the first transmission member 310 to rotate around the first axis 314, which is parallel to the second direction D2. The second transmission member 320 includes a second rotating part 321, a second input end 322, and a second output end. 323, the second rotating part 321 is located between the second input end 322 and the second output end 323, and is hinged to the support 100 around the second axis 326. The second input end 322 is in transmission cooperation with the driving end of the packaging drive mechanism 200. The packaging drive mechanism 200 is used to drive the second transmission member 320 to rotate around the second axis 326. The second axis 326 is parallel to the second direction D2. The end cap mechanism 400 is located on one side of the packaging drive mechanism 200 along the first direction D1. The end cap mechanism 400 includes a first end cap 410 and a second end cap 420. The first end cap 410 and the second end cap 420 are movably disposed on the support 100 along the third direction D3. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other. The first end cap 410 is in transmission cooperation with the first output end 313, and the second end cap 420 is in transmission cooperation with the second output end 323. The hinged transmission mechanism 300 is used to drive the first end cap 410 and the second end cap 420 to move closer to each other.

[0051] Specifically, the first direction D1 refers to Figures 1 to 3 The vertical direction refers to the direction from the end cap mechanism 400 to the encapsulation drive mechanism 200, and the horizontal direction refers to the direction from the encapsulation drive mechanism 200 to the end cap mechanism 400; the second direction D2 refers to... Figure 3 The front and rear directions within. Both the first axis 314 and the second axis 326 are parallel to the second direction D2; the third direction D3 refers to... Figure 3 The left and right directions are shown in the figure. Left refers to the direction from the second end cap 420 to the first end cap 410, and right refers to the direction from the first end cap 410 to the second end cap 420. It is understood that in an actual production line, the encapsulation drive mechanism 200 and the end cap mechanism 400 can be arranged vertically as shown in the example, or horizontally (left and right) or front and back. Other mechanisms or components can be adjusted accordingly, and will not be described in detail here.

[0052] The packaging drive mechanism 200 and the end cap mechanism 400 of the packaging device provided in this embodiment are distributed along the first direction D1. The packaging drive mechanism 200 drives the end cap mechanism 400 through the rotation of the hinged transmission mechanism 300, bringing the first end cap 410 and the second end cap 420 closer together. It can be seen that this packaging device only needs one packaging drive mechanism 200 to bring the first end cap 410 and the second end cap 420 closer together, reducing the overall size of the packaging device and making it easier to install in environments with limited space. Furthermore, the packaging drive mechanism 200 and the end cap mechanism 400 are connected by the rotation of the first transmission member 310 and the second transmission member 320, reducing the space required to drive the first end cap 410 and the second end cap 420 closer together, thus reducing the space required for the packaging device to operate and making it easier to install in environments with limited space.

[0053] For example, when the encapsulation drive mechanism 200 and the end cap mechanism 400 adopt... Figures 1 to 5 In the example arrangement shown, where both are arranged vertically, compared to the scheme where both end caps are equipped with drive mechanisms and the drive mechanisms are arranged on the left and right sides of the two end caps, the space occupied by the packaging device in the horizontal direction can be effectively reduced, making the structure of the packaging equipment more compact.

[0054] Furthermore, the support 100 includes a support body 110, a first hinge portion 120, and a second hinge portion 130, wherein the first hinge portion 120 and the second hinge portion 130 are both connected to the support body 110, the first rotating portion 311 is hinged to the first hinge portion 120, and the second rotating portion 321 is hinged to the second hinge portion 130.

[0055] Optionally, the encapsulation drive mechanism 200 includes a drive block 210 and an encapsulation drive component 220. The drive block 210 is located between the encapsulation drive component 220 and the end cap mechanism 400. The drive end of the encapsulation drive component 220 is connected to the drive block 210 and can drive the drive block 210 to reciprocate along the first direction D1. The drive block 210 has a first slope 211 and a second slope 212 on the side away from the end cap mechanism 400. Along the direction from the end cap mechanism 400 to the encapsulation drive mechanism 200, the first slope 211 and the second slope 212 are inclined in a direction that approaches each other. The first input end 312 is driven to the first slope 211, and the first output end 313 is located on the side of the first end cap 410 away from the second end cap 420. The second input end 322 is driven to the second slope 212, and the second output end 323 is located on the side of the second end cap 420 away from the first end cap 410.

[0056] by Figure 3Taking the direction shown as an example, when the encapsulation drive 220 drives the drive block 210 to move upward, the first slope 211 drives the first input end 312 upward, causing the first transmission member 310 to rotate around the first axis 314. This, in turn, causes the first output end 313 to push the first end cap 410 away from the side of the second end cap 420, thus moving the first end cap 410 towards the second end cap 420. Furthermore, when the encapsulation drive 220 drives the drive block 210 to move upward, the second slope 212 drives the second input end 322 upward, causing the second transmission member 320 to rotate around the second axis 326. This, in turn, causes the second output end 323 to push the second end cap 420 away from the side of the first end cap 410, thus moving the second end cap 420 towards the first end cap 410. This achieves the effect of bringing the first end cap 410 and the second end cap 420 closer together.

[0057] In this embodiment, the first output terminal 313 is located on the side of the first end cap 410 away from the second end cap 420, so as to push the first end cap 410 to move towards the second end cap 420, and the second output terminal 323 is located on the side of the second end cap 420 away from the first end cap 410, so as to push the second end cap 420 to move towards the first end cap 410. In other embodiments, the first output end 313 may be located on top of the first end cap 410, and the second output end 323 may be located on top of the second end cap 420, so that the first end cap 410 and the second end cap 420 are close to each other. For example, in other embodiments, the top of the first end cap 410 is connected to a first slide rod, the first slide rod is spaced apart from the top of the first end cap 410, and the axis of the first slide rod is parallel to the second direction D2. The first output end 313 is provided with a first slide groove, the opening of the first slide groove faces the first end cap 410, and the first slide groove passes through both sides of the first output end 313 along the second direction D2. The first slide rod slides through the first slide groove. When the first transmission member 310 rotates, the inner wall of the first slide groove applies a pushing force to the first slide rod, so that the first end cap 410 moves toward the second end cap 420. The top of the second end cap 420 is connected to a second slide rod, which is spaced apart from the top of the second end cap 420. The axis of the second slide rod is parallel to the second direction D2. The second output end 323 is provided with a second slide groove, the opening of which faces the second end cap 420. The second slide groove passes through both sides of the second output end 323 along the second direction D2. The second slide rod slides through the second slide groove. When the first transmission member 310 rotates, the inner wall of the second slide groove applies a pushing force to the second slide rod, so that the second end cap 420 moves toward the first end cap 410.

[0058] Furthermore, the first transmission member 310 includes a first input portion 317 and a first output portion 318. The free end of the first input portion 317 forms a first input terminal 312, and the free end of the first output portion 318 forms a first output terminal 313. The other end of the first input portion 317 is connected to the other end of the first output portion 318, and the connection point is a first rotating portion 311. The angle between the first input portion 317 and the first output portion 318 facing the second transmission member 320 is an obtuse angle. This reduces the rotation space required when the first transmission member 310 rotates, which is beneficial for further reducing the volume of the packaging device. Of course, in other embodiments, the first transmission member 310 can also be a straight rod structure.

[0059] Optionally, the second transmission member 320 includes a second input portion 327 and a second output portion 328. The free end of the second input portion 327 forms a second input terminal 322, and the free end of the second output portion 328 forms a second output terminal 323. The other end of the second input portion 327 is connected to the other end of the second output portion 328, and the connection point is a second rotating portion 321. The angle between the second input portion 327 and the second output portion 328 facing the first transmission member 310 is an obtuse angle. This reduces the rotation space required when the second transmission member 320 rotates, which is beneficial for further reducing the volume of the packaging device. Of course, in other embodiments, the second transmission member 320 can also be a straight rod structure.

[0060] Optionally, the encapsulation drive mechanism 200 further includes a regulating valve and an air supply source (neither the regulating valve nor the air supply source is shown in the figure). The encapsulation drive component 220 is a first linear cylinder. The air supply source is connected to the air inlet of the first linear cylinder through the regulating valve. By adjusting the opening of the regulating valve, the air intake of the first linear cylinder can be adjusted, thereby adjusting the driving force of the first linear cylinder to adjust the mutual pressing force between the first end cap 410 and the second end cap 420, so as to adapt to aluminum-plastic shells of different thicknesses. Of course, in other embodiments, the encapsulation drive component 220 can also be a drive element such as a lead screw advance motor.

[0061] Furthermore, the regulating valve can be an electro-proportional valve. In practical applications, multiple data sets can be pre-input into the controller connected to the electro-proportional valve. These data sets include multiple preset thickness values ​​and preset valve body opening values ​​corresponding to each preset thickness value. When encapsulating the aluminum-plastic shell, the preset thickness value is selected according to the actual thickness of the aluminum-plastic shell, and the preset valve body opening value corresponding to the preset thickness value is used as the actual valve body opening value. The valve body opening of the electro-proportional valve can then be adjusted to the above-mentioned actual valve body opening value. The specific structure and working principle of the above-mentioned electro-proportional valve are all existing technologies and will not be described in detail here.

[0062] Optionally, a first input roller 315 is rotatably connected to the first input terminal 312. The wheel surface of the first input roller 315 contacts the first slope 211. When the encapsulated driving member 220 drives the driving block 210 to move up and down, the first input roller 315 rolls on the first slope 211, thereby reducing the friction force on the first slope 211 and reducing the probability of wear on the first slope 211. Of course, in other embodiments, the first input terminal 312 can also be slidably connected to the first slope 211.

[0063] Optionally, a second input roller 324 is rotatably connected to the second input terminal 322. The wheel surface of the second input roller 324 contacts the second slope 212. When the encapsulated drive member 220 drives the drive block 210 to move up and down, the second input roller 324 rolls on the second slope 212, thereby reducing the friction force on the second slope 212 and reducing the probability of wear on the second slope 212. Of course, in other embodiments, the second input terminal 322 can also be slidably connected to the second slope 212.

[0064] Optionally, the first output end 313 is rotatably connected to a first output roller 316. The wheel surface of the first output roller 316 contacts the side of the first end cap 410 opposite to the second end cap 420. When the encapsulation drive member 220 drives the drive block 210 to move up and down, the first output roller 316 rolls on the side of the first end cap 410 opposite to the second end cap 420, thereby reducing the friction force on the first end cap 410 and reducing the probability of wear problems on the first end cap 410. Of course, in other embodiments, the first output end 313 can also be slidably connected to the side of the first end cap 410 opposite to the second end cap 420.

[0065] Optionally, a second output roller 325 is rotatably connected to the second output terminal 323. The wheel surface of the second output roller 325 contacts the side of the second end cap 420 opposite to the first end cap 410. When the encapsulation drive member 220 drives the drive block 210 to move up and down, the second output roller 325 rolls on the side of the second end cap 420 opposite to the first end cap 410, thereby reducing the friction force on the second end cap 420 and reducing the probability of wear problems on the second end cap 420. Of course, in other embodiments, the second output terminal 323 can also be slidably connected to the side of the second end cap 420 opposite to the first end cap 410.

[0066] In practical applications, rotating elements such as bearings or rollers can be selected as the first input roller 315, the second input roller 324, the first output roller 316, and the second output roller 325.

[0067] Optionally, the packaging device further includes a reset mechanism 500, which includes a first reset member 510, a second reset member 520, and an elastic member 530. The first reset member 510 is connected to the first end cap 410, the second reset member 520 is connected to the second end cap 420, and the elastic member 530 is located between the first reset member 510 and the second reset member 520. When the first end cap 410 and the second end cap 420 approach each other, the elastic member 530 is in a compressed state. At this time, the first output roller 316 abuts against the side of the first end cap 410 away from the second end cap 420, and the second output roller 325 abuts against the side of the second end cap 420 away from the first end cap 410, so that the first end cap 410 and the second end cap 420 are subjected to mutually pointing forces, thereby causing the first end cap 410 and the second end cap 420 to apply a compressive force to the elastic member 530 through the first reset member 510 and the second reset member 520, respectively. Figure 3 Taking the direction shown as an example, when the encapsulation drive member 220 drives the drive block 210 to move downward, the first transmission member 310 rotates in the opposite direction around the first axis 314, and the second transmission member 320 rotates in the opposite direction around the second axis 326, so that the first output roller 316 separates from the first end cap 410, and the second output roller 325 separates from the second end cap 420. The first end cap 410 and the second end cap 420 are no longer subjected to mutually pointing forces. Therefore, the first end cap 410 and the second end cap 420 no longer apply a squeezing force to the elastic member 530 through the first reset member 510 and the second reset member 520. The elastic member 530 rebounds, and the first reset member 510 and the second reset member 520 respectively drive the first end cap 410 and the second end cap 420 to move in mutually opposite directions, so as to achieve the effect of resetting the end cap mechanism 400.

[0068] Furthermore, the elastic element 530 can be a spring or a rubber element with a certain degree of elasticity.

[0069] In this embodiment, the separation of the first end cap 410 and the second end cap 420 is achieved by the rebound action of the elastic element 530. In other embodiments, a power-driven method can also be used to achieve the separation of the first end cap 410 and the second end cap 420. Exemplarily, in other embodiments, the reset mechanism 500 includes a first electric telescopic rod and a second electric telescopic rod. The fixed ends of the first and second electric telescopic rods are both connected to the support 100. The axes of the first and second electric telescopic rods are both parallel to the third direction D3. The telescopic end of the first electric telescopic rod is connected to the first end cap 410, and the telescopic end of the second electric telescopic rod is connected to the second end cap 420. When the first end cap 410 and the second end cap 420 approach each other, both the first and second electric telescopic rods extend. When the first end cap 410 and the second end cap 420 move away from each other, both the first and second electric telescopic rods shorten, thereby achieving the reset effect of the end cap mechanism 400.

[0070] Furthermore, the reset mechanism 500 also includes a guide rod 540, which is connected to the support body 110. The elastic element 530 is sleeved on the guide rod 540 to provide radial limiting for the elastic element 530 and prevent radial deformation of the elastic element 530.

[0071] Furthermore, the first reset member 510 and the second reset member 520 are both slidably sleeved on the guide rod 540 to guide the first reset member 510 and the second reset member 520, thereby guiding the movement of the first end cap 410 and the second end cap 420.

[0072] Furthermore, the reset mechanism 500 also includes a first limiting member 551 and a second limiting member 552. Both the first limiting member 551 and the second limiting member 552 are connected to the support body 110. The first limiting member 551 and the second limiting member 552 are respectively sleeved and fixed at both ends of the guide rod 540, such that the first limiting member 551 is located on the side of the first reset member 510 away from the second reset member 520, and the second limiting member 552 is located on the side of the second reset member 520 away from the first reset member 510. The first limiting member 551 can limit the first reset member 510 to prevent it from falling off the guide rod 540, and the second limiting member 552 can limit the second reset member 520 to prevent it from falling off the guide rod 540.

[0073] Optionally, both the first end cap 410 and the second end cap 420 are provided with heating elements such as electric heating wires or electric heating plates. When the first end cap 410 and the second end cap 420 are pressed together to encapsulate the aluminum-plastic shell, the heating elements can heat the aluminum-plastic shell to improve the encapsulation effect.

[0074] Furthermore, both the first end cap 410 and the second end cap 420 are equipped with embedded Pt100 temperature sensors to detect the real-time temperature of the first end cap 410 and the second end cap 420.

[0075] Optionally, both the first end cap 410 and the second end cap 420 are made of aluminum nitride ceramic material. Aluminum nitride ceramic has good thermal shock resistance, which can improve the thermal shock resistance of the first end cap 410 and the second end cap 420.

[0076] Optionally, the first end cap 410 is provided with a first tooth-like structure (not shown in the figure) on the side facing the second end cap 420, and the second end cap 420 is provided with a second tooth-like structure (not shown in the figure) on the side facing the first end cap 410. The first tooth-like structure and the second tooth-like structure are arranged opposite each other, and the first tooth-like structure and the second tooth-like structure can interlock with each other to improve the sealing effect of the end cap mechanism 400 on the aluminum-plastic shell.

[0077] Optionally, the packaging device further includes a guiding mechanism, which includes a slide rail 610 and a slider 620. The slide rail 610 and the slider 620 are slidably engaged. The slide rail 610 extends along a third direction D3 and is mounted on the support body 110. There are two sliders 620, which are respectively located on the first end cap 410 and the second end cap 420, so that the two sliders 620 are slidably engaged with the same slide rail 610. This structure can improve the slidability of the first end cap 410 and the second end cap 420 in the third direction D3. The coaxiality of the first end cap 410 and the second end cap 420 is important, especially when the first end cap 410 has a first toothed structure and the second end cap 420 has a second toothed structure. The coaxiality of the first end cap 410 and the second end cap 420 needs to be high in order to make the first toothed structure and the second toothed structure mesh accurately. If the coaxiality of the first end cap 410 and the second end cap 420 is low, the first toothed structure and the second toothed structure may not mesh, or even the first toothed structure and the second toothed structure may interfere with each other and fail to encapsulate the aluminum-plastic shell.

[0078] like Figure 5 As shown, in this embodiment, the outer contour of the slide rail 610 forms a track, and the slider 620 has a groove covering the track, thereby forming a structure in which the slider 620 and the slide rail 610 slide in a sliding engagement. Of course, in other embodiments, the slide rail 610 may also have a groove, and the slider 620 may slide within the groove.

[0079] In this embodiment, one slider 620 is connected to the first end cap 410, and the other slider 620 is connected to the second end cap 420. That is, the first end cap 410 and the second end cap 420 and their corresponding sliders 620 are separate structures. Of course, in other embodiments, the first end cap 410 and the second end cap 420 and their corresponding sliders 620 can also be an integral structure, that is, grooves adapted to the slide rail 610 can be directly formed on the first end cap 410 and the second end cap 420.

[0080] In another embodiment, the slider 620 is disposed on the support body 110, and there are two slide rails 610, which are respectively disposed on the first end cap 410 and the second end cap 420, so as to improve the coaxiality of the first end cap 410 and the second end cap 420 in the third direction D3.

[0081] The packaging equipment provided in this embodiment can adopt any of the technical solutions or features of the packaging device described above. Therefore, the structure of the packaging equipment is relatively compact, which is beneficial for installing the packaging equipment in installation conditions with limited space.

[0082] Optionally, in the packaging equipment, the hinge transmission mechanism 300, the sealing mechanism 400, and the reset mechanism 500 are all located inside the vacuum chamber 1. The driving end of the sealing drive 2 is connected to the support body 110. The sealing drive 2 is used to drive the support body 110 to press and cover the opening of the vacuum chamber 1. The suction gas source (vacuum pump or other suction element) is connected to the vacuum chamber 1. When the soft-pack battery needs to be injected with liquid in a vacuum environment, the unsealed soft-pack battery can be placed in the vacuum chamber 1, so that the support body 110 is pressed and covered at the opening of the vacuum chamber 1. After the sealing mechanism 400 has finished sealing the aluminum-plastic shell (or before sealing), the suction gas source is activated to form a vacuum environment inside the vacuum chamber 1.

[0083] Furthermore, the sealing drive 2 can be a cylinder or a lead screw motor or other drive element. In this embodiment, the sealing drive 2 is a second linear cylinder. The drive end of the second linear cylinder is connected to the transmission plate 21. The side of the transmission plate 21 away from the second linear cylinder is connected to two transmission rods 22. The side of the transmission rods 22 away from the transmission plate 21 is connected to the support body 110, so that the second linear cylinder drives the support body 110 to reciprocate in the vertical direction.

[0084] Optionally, to improve the sealing between the support body 110 and the vacuum chamber 1, a sealing ring can be provided on the side of the support body 110 facing the vacuum chamber 1, or a sealing ring can be provided at the opening of the vacuum chamber 1.

[0085] Optionally, the packaging equipment includes multiple packaging devices. For example, the packaging equipment in this embodiment includes six packaging devices, which can simultaneously package six aluminum-plastic shells, improving packaging efficiency and making the overall structure of the packaging equipment more compact. In other embodiments, the number of packaging devices may be two, five, or eight, etc.

[0086] Furthermore, at least two of the multiple packaging devices are grouped together, and the elastic element 530, the first reset element 510, and the second reset element 520 in the same group of packaging devices are sleeved on the same guide rod 540. This reduces the number of parts in the packaging equipment and lowers the production cost of the packaging equipment.

[0087] In this embodiment, the six packaging devices are grouped in pairs, with two packaging devices in each group distributed along the third direction D3 and the three groups of packaging devices distributed along the second direction D2, so as to make full use of the installation space and make the packaging equipment more compact.

[0088] Furthermore, the reset mechanism 500 also includes a third limiting member 553, which is sleeved and fixed on the guide rod 540 and connected to the support body 110. In the same group of encapsulation devices, a third limiting member 553 is provided between adjacent first reset members 510 and second reset members 520 so that the third limiting member 553 can limit the adjacent first reset members 510 and second reset members 520 and avoid mutual interference between adjacent first reset members 510 and second reset members 520.

[0089] The packaging process of the packaging device provided in this embodiment is briefly described below:

[0090] See Figures 1 to 5 Taking the direction shown in the figure as an example, a robotic arm (not shown in the figure) is used to grab six unsealed pouch batteries at once and put these six unsealed pouch batteries into the vacuum box 11, so that each pouch battery corresponds to a sealing mechanism 400.

[0091] The sealing drive 2 drives the support body 110 to move in the direction toward the vacuum chamber 1, so that the support body 110 presses against the cover at the opening of the vacuum chamber 1.

[0092] When the encapsulation drive 220 is activated, it drives the drive block 210 to move upward, causing the first transmission member 310 to rotate counterclockwise around the first axis 314 and the second transmission member 320 to rotate clockwise around the second axis 326. The first output roller 316 abuts against the side of the first end cap 410 away from the second end cap 420, and the second output roller 325 abuts against the side of the second end cap 420 away from the first end cap 410. As the drive block 210 continues to move upward, the first output roller 316 and the second output roller 325 apply force to the first end cap 410 and the second end cap 420 respectively, causing the first end cap 410 and the second end cap 420 to move closer to each other. During this process, the elastic member 530 is compressed until the first end cap 410 and the second end cap 420 are pressed tightly against both sides of the aluminum-plastic shell.

[0093] The encapsulation drive component 220 drives the drive block 210 to move downward, causing the first transmission component 310 and the second transmission component 320 to rotate in opposite directions. The first output roller 316 separates from the first end cap 410, and the second output roller 325 separates from the second end cap 420. The elastic component 530 rebounds and drives the first end cap 410 and the second end cap 420 to separate from each other.

[0094] Start the air intake source to extract air from the vacuum chamber 1 to create a vacuum environment inside the vacuum chamber 1, and then inject electrolyte into the aluminum-plastic shell.

[0095] Depending on the specific process requirements, the suction gas source may be activated intermittently multiple times during the aluminum-plastic shell encapsulation process to perform multiple vacuum stages.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
