Preferably, the second glue wrapping mechanism 2 further comprises a second corner pressing assembly 23. The second corner-pressing member 23 is located at one side of the second side-pressing member 22. The second corner pressing component 23 in this embodiment is used to encapsulate an oblique angle between the D side and the C side of the battery cell 100, and specifically, the second gummed paper head 4001 leaking out of the second lateral gummed paper 400 is encapsulated on the oblique angle between the D side and the C side of the battery cell 100. The structure and the operation principle of the second corner pressing component 23 in this embodiment are the same as those of the corner indenting component 13, and are not described herein again. In a specific application, the indenting angle pushing block 1311 of the indenting angle edge component 13 is replaced by an indenting angle pushing block correspondingly in the second indenting angle component 23 corresponding to the oblique angle edge between the D side and the C side of the battery cell 100 for adaptation. Of course, when the connection angle between the D side and the C side varies, for example, the arc R angle, the indenting angle push 1311 of the indenting angle edge component 13 can be replaced by an R-angle push to fit the second indenting angle component 23.

Preferably, the second glue wrapping mechanism 2 further comprises a third corner pressing assembly 24. The third corner pressing assembly 24 is positioned on the side of the second corner pressing side assembly 22 away from the second corner pressing assembly 23. In the present embodiment, the third glue pressing assembly 24 encapsulates the third glue head 4002, from which the second side glue 400 leaks, on the chamfer between the D side of the battery cell 100 and the head of the battery cell 100. The third corner pressing assembly 24 can adopt a structure similar to that of the first corner pressing assembly 14, and can also adopt an existing corner pressing and rubber coating mechanism. The third press angle assembly 24 in the present embodiment includes a press angle driving cylinder 241, a driving plate 242, a driving roller 243, a press angle supporting table 244, a press angle slider 245, a press angle pressing block 246, a pressing block limiting plate 247, and a press angle spring (not shown). The corner pressing bearing platform 244 is integrally arranged with the glue pressing bearing platform 1201 of the second side pressing assembly 22, and the corner pressing driving cylinder 241 is arranged on the corner pressing bearing platform 244. One end of the driving plate 242 is connected to an output end of the pressing angle driving cylinder 241, and the driving roller 243 is rotatably connected to the other end of the driving plate 242. The corner pressing slider 245 is slidably connected to the corner pressing support 244, and has one end facing the driving roller 243. One end of the pressing angle block 246 is disposed on the pressing angle slider 245, and the other end of the pressing angle block is opposite to the chamfer between the D-side edge of the battery cell 100 and the head of the battery cell 100, preferably, the shape of the end of the pressing angle block 246 is matched with the shape of the chamfer between the D-side edge of the battery cell 100 and the head of the battery cell 100. The briquetting limiting plate 247 is arranged on the pressure angle bearing platform 244 and is positioned above the pressure angle sliding block 245, and the briquetting limiting plate 247 is positioned between the pressure angle briquetting 246 and the driving roller 243. The compression angle spring is located in the compression angle bearing platform 244, and two ends of the compression angle spring are respectively connected with one end of the compression angle bearing platform 244 and one end of the compression angle slider 245 close to the battery core 100. When pressing the angle, the angle pressing driving cylinder 241 drives the driving connecting plate 242 to move linearly, and drives the driving roller 243 to act on the angle pressing slider 245, so that the angle pressing slider 245 drives the angle pressing block 246 to move towards the chamfer between the D-side edge of the battery cell 100 and the head of the battery cell 100, and encapsulation is performed. At this time, the compression angle spring is compressed, after the encapsulation is completed, the driving state of the compression angle driving cylinder 241 disappears, the compression angle spring is compressed and acts on the compression angle sliding block 245 in a reverse direction, so that the compression angle sliding block 245 drives the compression angle pressing block 246 to move towards the pressing block limiting plate 247 and abut against the pressing block limiting plate 247 to wait for the next chamfering encapsulation.

Preferably, the second glue coating mechanism 2 further comprises a second glue coating deviation rectifying component 25. The second glue-jacking component 21, the second side pressing component 22, the second corner pressing component 23 and the third corner pressing component 24 are all arranged on the second glue-wrapping deviation-rectifying component 25. The deviation rectification before the D-side edge of the battery cell 100 is encapsulated by the second encapsulating component 25, and the structure and the actuation principle of the second encapsulating deviation rectification component 25 are consistent with those of the first encapsulating deviation rectification component 15, and are not described herein again.

Preferably, the second glue dispensing mechanism 2 further comprises a second lift drive assembly 26. The second lifting driving assembly 26 is used for lifting the glue pressing bearing platform of the second glue wrapping mechanism 2, so as to adjust the overall position of the second side pressing assembly 22, the second corner pressing assembly 23 and the third corner pressing assembly 24, and facilitate the glue wrapping operation. The structure and operation of the second lift drive assembly 26 are consistent with the structure and operation of the first lift drive assembly 16 and will not be described in detail herein.

It should be noted that, in the encapsulation device in this embodiment, two side edges, i.e., B and D, of the battery cell 100 and a part of the concave arc angle structure E close to the side edge of B are encapsulated; when the battery cell 100 needs to be integrally encapsulated, the two sides of the battery cell 100A and the battery cell C and the other part of the concave arc angle structure E close to the side of the battery cell A are encapsulated by arranging another encapsulation device.

In conclusion, the encapsulation device in the embodiment can adapt to encapsulation of the regular and irregular-shaped battery cores, and the encapsulation is carried out after deviation rectification, so that the encapsulation is accurate, and the encapsulation quality is guaranteed.
