Battery cell assembly machine

Abstract

The present invention provides a battery cell assembling machine, comprising a transport device and a assembling device. The transport device's cell manipulator for coated cells can clamp and absorb the cell body and insulating film, safely transporting the coated cells to the assembling device. The assembling device includes a assembling support, a assembling translation mechanism, a assembling flip mechanism, an insulating film clamping mechanism, a cell body clamping mechanism, a top cover clamping mechanism, and a tab support mechanism. The cell body clamping mechanism can clamp the cell body, the insulating film clamping mechanism can clamp the insulating film, the top cover clamping mechanism can clamp the top cover, and the tab support mechanism can support the tab. The transport device's cell assembling manipulator then safely transports the assembled cells off the machine. During the transport and assembling process, the original relative positions and fitting relationship of the two cell bodies, top cover, and insulating film are not altered, nor are the tabs and insulating film twisted, pushed, or pulled. This prevents the cell body, insulating film, and top cover from loosening during the flipping process, and prevents damage to the tabs.

Description

Technical Field

[0001] The present invention belongs to the technical field of battery production equipment, and in particular relates to a battery cell assembling machine. Background Art

[0002] Please see Figures 1 to 2 The film-coated battery cell after flexible connection welding includes two battery cell bodies 11 and a top cover 12. A cathode ear 11a and an anode ear 11b of each of the two battery cell bodies 11 have been welded to the cathode column and the anode column of the top cover 12. An insulating film 13 is sandwiched between each large surface of the two battery cell bodies 11 and the top cover 12. The two battery cell bodies 11 are separated and spread flat on both sides of the top cover 12. Each large surface of the two battery cell bodies 11 is pressed on an insulating film 13. The two insulating films 13 are indented and narrower than the rounded corners of the battery cell body 11 on both sides in the width direction of the battery cell body 11. The two insulating films 13 are higher than the height of the battery cell body 11 in the height direction of the battery cell body 11 by about the thickness of the battery cell body 11 plus 3mm. The two insulating films 13 are pre-pressed with a horizontal through-bending line 13a that is easy to be bent at the position aligned with the bottom surface of the two battery cell bodies 11. After welding, you first need to fold the two battery cells together with the insulation film 13 around the top cover 12 and flip them over. Figure 3 The requirements for transporting and assembling the membrane cell 10 are: the relative position and fitting relationship of the two cell bodies 11 and the insulating film 13 cannot be changed, and the cathode ear 11a, anode ear 11b and insulating film 13 cannot be twisted or pushed or pulled.
