In the existing patent, the Chinese patent document with the application number 201820570816.1 discloses a top sealing device for a lithium battery encapsulation device, which includes a support, the support is provided with a top sealing upper head and a top sealing lower head arranged directly below the top sealing upper head, a lifting tray mechanism is arranged at the front end of the top sealing lower head, a first heating plate is arranged at the lower end of the top sealing upper head, a second heating plate is arranged at the upper end of the top sealing lower head, and a first driving mechanism for driving the top sealing upper head to move down is arranged above the top sealing upper head; in actual application, when the external manipulator clamps the lithium battery from the previous process to the top sealing device, the lifting tray mechanism is used to lift and hold the lithium battery, and the encapsulation process starts.

[0021] For the convenience of those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model.

[0022] As Figures 1 to 3 shown, a battery encapsulation device provided by the present utility model includes an encapsulation base 1, a lower head 2 installed on the encapsulation base 1, an upper head 3 arranged above the lower head 2 in a lifting manner, an encapsulation driving mechanism 4 installed on the encapsulation base 1 and used to drive the upper head 3 to approach or move away from the lower head 2, a support platform 5 arranged outside the lower head 2, a pressing plate 6 arranged above the support platform 5 in a lifting manner and located outside the upper head 3, and a pressing driving mechanism 7 installed on the encapsulation base 1 and used to drive the pressing plate 6 to approach or move away from the support platform 5; specifically, the encapsulation driving mechanism 4 can adopt a motor screw module.

[0023] In practical applications, the battery to be encapsulated is placed on the support platform 5, and the encapsulation part of the battery to be encapsulated is located on the lower head 2. Then, the pressing driving mechanism 7 drives the pressing plate 6 to move downward close to the battery until the pressing plate 6 presses the battery on the support platform 5. Then, the encapsulation driving mechanism 4 drives the upper head 3 to move close to the lower head 2 until the upper head 3 and the lower head 2 cooperate to encapsulate the battery. Before encapsulating the battery, the present utility model presses the battery through the pressing plate 6, improving the stability and quality of battery encapsulation, and it is not easy to appear concave points or concave traces. Compared with the traditional method of using an encapsulation fixture and an encapsulation mechanism to encapsulate the battery, the present utility model can reduce costs. The present utility model is particularly suitable for side sealing and bottom sealing of batteries.

[0024] In this embodiment, the upper head 3 is connected to the driving end of the encapsulation driving mechanism 4 via an upper heat insulation plate 8. With this structural design, the upper heat insulation plate 8 plays a role in heat insulation, and the heat of the upper head 3 will not be transferred to the encapsulation driving mechanism 4, avoiding the encapsulation driving mechanism 4 working under high temperature for a long time and playing a protective role for the encapsulation driving mechanism 4.

[0025] In this embodiment, the lower head 2 is connected to the encapsulation base 1 via a lower heat insulation plate 9. With this structural design, the lower heat insulation plate 9 plays a role in heat insulation, avoiding the heat of the lower head 2 being transferred to the encapsulation base 1.

[0026] In this embodiment, the battery encapsulation device further includes a lifting driving mechanism 10. The support platform 5 is connected to the lifting end of the lifting driving mechanism 10, and the lifting driving mechanism 10 is used to drive the support platform 5 to lift. Specifically, the lifting driving mechanism 10 can adopt a motor screw module. In practical applications, the lifting driving mechanism 10 drives the support platform 5 to lift to adjust the height of the support platform 5, facilitating the support of the battery.

[0027] In this embodiment, the pressing drive mechanism 7 includes a pressing driver 11, and the pressing end of the pressing driver 11 is connected to the pressing plate 6; specifically, the pressing driver 11 can be a cylinder. In practical applications, the pressing driver 11 drives the pressing plate 6 to move downward and presses the battery against the support table 5.

[0028] In this embodiment, the pressing plate 6 is fixedly connected to the pressing end of the pressing driver 11 via a downward heat insulation plate 12. The downward heat insulation plate 12 plays a role in heat insulation, reducing the heat transfer between the pressing plate 6 and the pressing driver 11, and preventing the heat of the pressing plate 6 from being transferred to the pressing driver 11.

[0029] In this embodiment, the pressing drive mechanism 7 further includes a telescopic driver 13. One end of the telescopic driver 13 is fixedly connected to the encapsulation base 1, and the other end of the telescopic driver 13 is fixedly connected to the end of the pressing driver 11 away from the pressing plate 6; when the telescopic driver 13 is in the extended state, the pressing plate 6 is located outside the upper head 3 and covers the upper head 3; when the telescopic driver 13 is in the contracted state, the pressing plate 6 is located above the outside of the upper head 3; specifically, the telescopic driver 13 can be a cylinder. In the working state, the telescopic driver 13 is in the extended state, and the pressing plate 6 covers the upper head 3, preventing the upper head 3 from being exposed and improving the safety performance of use; in the maintenance state, the telescopic driver 13 is in the contracted state, and the pressing plate 6 moves upward above the upper head 3, exposing the upper head 3, which is convenient for disassembling, assembling and maintaining the upper head 3.

[0030] In this embodiment, the pressing plate 6 is provided with a cooling channel 16. In practical applications, when the upper head 3 and the lower head 2 cooperate to encapsulate the battery, the heat of the head will be transferred to the battery. Cold air or coolant is introduced into the cooling channel 16 to cool the pressing plate 6, thereby cooling the non-encapsulated part of the battery and preventing the non-encapsulated part of the battery from being scalded and affecting the battery quality.

[0031] In this embodiment, the pressing plate 6 is connected with a slider 14, and the slider 14 is slidably connected to the encapsulation base 1. During the lifting process of the pressing plate 6, the slider 14 slides relative to the encapsulation base 1, improving the lifting stability of the pressing plate 6.

[0032] In this embodiment, the slider 14 is provided with a stroke limit block 15. During the downward movement of the pressing plate 6, when the stroke limit block 15 abuts against the encapsulation base 1, it proves that the slider 14 and the pressing plate 6 have moved down to the lower limit, preventing the pressing plate 6 from moving down excessively and damaging the battery.

[0033] All the technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
