[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] The electrothermal film encapsulation device of the present application embodiment will now be described with reference to the accompanying drawings.

[0020] like Figures 1-6 As shown, the electrothermal film encapsulation device of this application embodiment may include a worktable 10 and a mounting mechanism and an encapsulation mechanism 30 disposed on the worktable 10.

[0021] The assembly mechanism may include two symmetrically arranged side rails 21, each side rail 21 being linearly arranged, and each side rail 21 may include a first track 211 and a second track 212 that are slidably nested together. One end of the second track 212 is slidably embedded in the first track 211 via a telescopic component 13. The telescopic component 13 described in this embodiment has the function of controlling the sliding of the second track 212 relative to the first track 211, and the telescopic component 13 may be a cylinder, a telescopic motor 41, etc.

[0022] The first track 211 is disposed on the surface of the worktable 10, and multiple drive wheels 23 are movably disposed on both the upper and lower sides of the slide rail of the first track 211. Through holes 2111 are opened on both the upper and lower sides of the first track 211, and the multiple drive wheels 23 in two rows are respectively disposed in the two through holes 2111, with the multiple drive wheels 23 in the lower row movably embedded in the surface of the worktable 10. All the multiple drive wheels 23 are connected to the drive assembly 40. It should be noted that the drive assembly 40 described in this embodiment has the function of controlling the multiple drive wheels 23 on the first track 211 to operate synchronously, and the rotation directions of the multiple drive wheels 23 in the upper and lower rows are opposite. Specifically, the drive assembly 40 may include a motor 41, a worm gear 42, and multiple turbines 43, wherein one end of the worm gear 42 is connected to the output end of the motor 41, and the other end is disposed on the worktable 10 through a bearing seat. The multiple turbines 43 are arranged in two rows, and the two rows of turbines 43 respectively mesh with the upper and lower sides of the worm gear 42. The worktable 10 has a housing 11 on each side, the housing 11 is installed through the worktable 10, and the drive assembly 40 is installed inside the housing 11.

[0023] In this embodiment, two drive components 40 are provided, and the two drive components 40 are respectively connected to multiple drive wheels 23 on two first tracks 211. The two motors 41 start synchronously, and after the motors 41 start, they can drive the worm gear 42 connected to them to rotate. The upper and lower rows of drive wheels 23 meshing with the worm gear 42 rotate synchronously and in opposite directions, thereby conveying the heating film 92 towards the outer casing 91.

[0024] Currently, before encapsulation, the surface of the heating film 92 is typically coated with an aluminum film (usually aluminum foil tape or composite aluminum film). This ensures even heat distribution and conduction, preventing localized overheating and providing protection. In this application, multiple drive wheels 23 contact the sides of the heating film 92 for transport, effectively avoiding damage to the aluminum film on the surface of the heating film 92. Simultaneously, two air blowing pipes 61 can blow air onto the upper and lower sides of the heating film 92 respectively, assisting the heating film 92 in smoothly entering the outer casing 91, significantly reducing friction between the aluminum film on the surface of the heating film 92 and the outer casing 91 during the process.

[0025] A ramp 70 is provided at one end of the first track 211 away from the second track 212. The ramp 70 facilitates the smooth entry of the head end of the electric heating film 92 into the slide rail of the first track 211.

[0026] The second track 212 has air blowing pipes 61 running through its upper and lower sides and an air intake pipe 71 running through its middle. The first track 211 has an air intake pipe 72 and an air blowing pipe 62 that move through it. One end of the air intake pipe 72 is connected to the air intake pipe 71, and the other end moves through the first track 211 and connects to an external negative pressure unit. One end of the air blowing pipe 61 is connected to two corresponding air intake pipes 71, and the other end moves through the first track 211 and connects to an external blower. Both the external negative pressure unit and the external blower can be installed individually. A single external negative pressure unit can connect to the air intake pipes 71 in the two side tracks 21, and a single external blower can connect to the air blowing pipes 61 in the two side tracks 21.

[0027] The second track 212 is C-shaped, and the slide rail of the second track 212 is located in the middle of the second track 212. The arc surfaces of the second track 212 are set far apart, which can smoothly open the opening of the outer jacket 91.

[0028] The packaging mechanism 30 may include a support frame 31 and a pressure plate assembly 32, wherein the support frame 31 is disposed on the worktable 10 and is arranged in a U-shape. The pressure plate assembly 32 may include an upper pressure plate 321 and a lower pressure plate 322, which are correspondingly positioned. The lower pressure plate 322 is embedded in the surface of the workbench 10. The upper pressure plate 321 may include a main pressure plate 3211 and two side pressure plates 3212. The main pressure plate 3211 is movably mounted on the support frame 31 via a first lifting member 51. The two side pressure plates 3212 are slidably mounted on both sides of the main pressure plate 3211 via a second lifting member 52. The two side pressure plates 3212 are at the same height and are both greater than the height of the main pressure plate 3211. This design allows the main pressure plate 3211 to contact the lower pressure plate 322 before the side pressure plates 3212, thus achieving heat sealing of the middle part of the opening of the outer jacket 91. After vacuuming the inner part of the outer jacket 91, the two side pressure plates 3212 can be controlled to move downward to achieve heat sealing of both sides of the opening of the outer jacket 91.

[0029] It should be noted that the first lifting member 51 described in this embodiment has the function of controlling the main pressure plate 3211 and the second lifting member 52 and the two side pressure plates 3212 to move synchronously and vertically, while the second lifting member 52 is responsible for controlling the vertical movement of the two side pressure plates 3212 relative to the main pressure plate 3211. Both the first lifting member 51 and the second lifting member 52 can be devices such as cylinders.

[0030] In addition, the output end of the second lifting member 52 can be connected to both side pressure plates 3212 simultaneously through a U-shaped connecting frame 521.

[0031] In the embodiments of this application, reference is made to Figure 2 After the upper pressure plate 321 moves downward, it aligns with the lower pressure plate 322, effectively compacting the opening side of the outer jacket 91 during this process. Furthermore, since a wire 921 is located at the center of the end of the heating film 92, a storage opening 911 for storing the wire 921 is provided in the center of the opening of the outer jacket 91, through which the wire 921 can pass. When the upper pressure plate 321 and the lower pressure plate 322 are fully fitted together, the storage opening 911 is simultaneously sealed.

[0032] It should be noted that the upper pressure plate 321 and the lower pressure plate 322 described in this embodiment both have independent heating functions. Specifically, electric heating units can be embedded inside the main pressure plate 3211, the two side pressure plates 3212, and the lower pressure plate 322. By energizing these electric heating units, the corresponding main pressure plate 3211, side pressure plate 3212, or lower pressure plate 322 can be heated, thereby facilitating heat sealing operations.

[0033] It may also include a pressure roller 80, which is rotatably mounted on the surface of the worktable 10. The worktable 10 has moving rails 12 on both sides, and moving seats 121 are slidably mounted within the moving rails 12. The two ends of the pressure roller 80 are movably connected to the two moving seats 121 respectively. The outer jacket 91 is placed between the two moving rails 12 and remains parallel to them. During the movement of the pressure roller 80 along the moving rails 12, it can moderately roll the surface of the outer jacket 91 without damaging it or its internal heating film 92, thereby effectively expelling air from inside the outer jacket 91 and facilitating subsequent rapid vacuuming operations.

[0034] Specifically, during the assembly and encapsulation of the heating film 92 and the outer casing 91, the personnel first place the outer casing 91 over the outside of the two second tracks 212, ensuring that the two second tracks 212 can provide taut support to both sides of the outer casing 91. Next, the first end of the heating film 92 is introduced between the two first tracks 211 via the ramp 70, allowing both sides of the heating film 92 to enter the slide rails of the first tracks 211 and pass through the drive wheels 23 on the upper and lower sides. The two drive components 40 control the multiple drive wheels 23 on both sides, driving the heating film 92 to move and enter the outer casing 91 through its opening, thus initiating the assembly process. During this process, the operator can use a blower to blow air into the air pipe 62, which in turn blows air into the air pipes 61 within the two side rails 21, thereby blowing air onto the upper and lower sides of the heating film 92 to facilitate its smooth entry.

[0035] After the heating film 92 is fully inserted into the outer casing 91, the wire 921 at the end of the heating film 92 is aligned so that it passes through the receiving opening 911 in the middle of the opening of the outer casing 91. Then, without moving the work position, vacuum sealing can be performed directly. The operator activates the first lifting component 51, causing the upper pressure plate 321 to move downwards. The main pressure plate 3211 first contacts the lower pressure plate 322 and heat-seals the middle of the bag opening. Next, the operator can control the pressure roller 80 to move along the moving rail 12, rolling it on the surface of the outer casing 91 to expel some of the air inside the outer casing 91 through the opening.

[0036] Finally, the vacuum pump is used to control the suction pipe 72 and suction line 71 to exhaust air from the inside of the outer jacket 91. After vacuuming, the second track 212 is quickly retracted towards the first track 211 via the telescopic component 13, so that the two first tracks 211 are pulled out from the inside of the outer jacket 91. Subsequently, the second lifting component 52 is used to quickly move the two side pressure plates 3212 downward to complete the heat sealing operation on both sides of the opening of the outer jacket 91.

[0037] In summary, the electrothermal film encapsulation device of this application embodiment, through the coordinated cooperation of the assembly mechanism and the encapsulation mechanism, enables the electrothermal film and outer jacket to be directly vacuum-sealed after assembly without moving the work position, thereby achieving rapid encapsulation of the electrothermal film and outer jacket and improving encapsulation efficiency.
