[0024] Specifically, refer to Figure 1-2As shown in the figure, the present utility model provides a packaging mechanism for battery packaging, which includes a packaging machine frame 310, a turntable base 320 provided at the lower end of the packaging machine frame 310 and capable of driving the packaging machine frame 310 to rotate, a rotation driving component 330 for driving the turntable base 320 to rotate, and at least two groups of heat sealing components 340 provided on the packaging machine frame 310. The at least two groups of heat sealing components 340 are arranged back to back along the packaging machine frame 310. Each group of heat sealing components 340 includes two heat sealing parts 341 arranged side by side and at intervals. The two heat sealing parts 341 are respectively used to flatten the two end tabs of the battery cell in the clamped packaging shell and simultaneously heat seal the two ends of the clamped packaging shell. Each group of heat sealing parts 340 can simultaneously flatten and heat seal the two ends of the packaging shell, and during the rotation of the packaging machine frame 310, the heat sealing parts 341 heat seal the clamped packaging shell, with high packaging efficiency.

[0025] The packaging mechanism and the automatic packaging equipment for battery packaging provided by the present utility model are configured with at least two groups of heat sealing components 340 for simultaneous placement on the packaging machine frame 310, and the mechanism can rotate around the central axis. In this embodiment, there are four groups of heat sealing components 340 on the packaging machine frame 310. While two groups of heat sealing components 340 receive two packaging shells, the other two groups of heat sealing components 340 transfer the two heat-sealed packaging shells to the detection mechanism. While the packaging equipment rotates around the central axis, the heat sealing components 340 heat seal the two ends of the packaging shell containing the battery cell unit, saving time and having high packaging efficiency.

[0026] Specifically, the upper end of the packaging machine frame 310 is a packaging machine case 311, and the lower end is a chassis 312. A mounting frame 313 is vertically provided between the packaging machine case 311 and the chassis 312. At least two groups of heat sealing components 340 are arranged back to back on the mounting frame 313. Such a setting can make the machine occupy less space and have a compact structure.

[0027] Furthermore, there are four groups of heat sealing components 340, and two groups of heat sealing components 340 are arranged back to back on the mounting frame 313.

The lower heat-insulating member 3417 is fixedly arranged on the chassis 312. Heating devices (not shown) are arranged in both the upper head 3415 and the lower head 3416. The lower end of the upper head 3415 is in a stepped shape. The design of the stepped lower end of the upper head 3415 compresses the edge of the clamping and encapsulating shell to be more fitting.

[0029] Further, a slide rail 3131 is vertically arranged on the mounting frame 313. The adjusting plate 3413 is slidably connected in the slide rail 3131. The upper head 3415 can slide up and down in the slide rail 3131 under the drive of the adjusting plate 3413, which is convenient for putting in / taking out the clamping and encapsulating shell.

[0030] Further, an adsorption component (not shown) is arranged at the upper end of the lower head 3416. The adsorption component is used to fix the encapsulated shell after heat-sealing. In practical applications, other methods can also be used to fix the encapsulated shell.

The cutting and shell punching mechanism 100 includes a packaging tape feeding device 110, a cutting device 190, a shell punching device 120, and a moving device 180. In this embodiment, the packaging tape 910 is taken as an aluminum plastic film tape for example. The packaging tape 910 can be punched to form a packaging shell (not shown), that is, an aluminum plastic film shell for battery cell packaging. Each packaging shell has two semi-cylindrical slots, that is, battery cell semi-slots. The two slots are symmetrically distributed on both sides of the midline of the packaging shell along the length direction. The packaging shell can be folded along the midline to package the battery cell in the packaging shell.
