[0047] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0048] Recently, a new battery string soldering process, namely the overlapping string soldering process, has been studied in the industry. As Figure 1 shown, it is a schematic structural diagram of a battery string formed by the overlapping string soldering process. In two adjacent battery cells 100 of the battery string formed by this string soldering process: the head of the subsequent battery cell 100 overlaps the tail of the previous battery cell 100 to form an overlapping part, the front section of the solder tape 101 is located on the upper surface of the previous battery cell 100, and the rear section of the solder tape 101 is located on the lower surface of the subsequent battery cell 100.

[0049] For the above-mentioned overlapping string soldering process, glue needs to be applied between the two battery cells at the overlapping part to reduce the probability of cracking at the overlapping part of two adjacent battery cells 100 during subsequent lamination. Therefore, how to apply the colloid between the overlapping parts of the two battery cells has become a difficult problem to be solved urgently.

[0050] Therefore, the present application proposes a blowing device. Please refer to Figure 2 and Figure 3 shown.

Among them: an air flow output port 21 is formed on the blowing assembly 20, the blowing assembly 20 is inclinedly mounted on the mounting frame 10, and the air flow provided by the blowing assembly 20 flows obliquely downward after being output from the air flow output port 21 to blow the colloid 102 on the battery string between the overlapping parts of two adjacent adjacent battery cells 100. Among them: the battery string is formed by connecting at least two battery cells 100 and at least one group of solder tapes 101 in series. The front section of each group of solder tapes 101 is located on the upper surface of the previous battery cell 100, the rear section of each group of solder tapes 101 is located on the lower surface of the subsequent battery cell 100, the edges of two adjacent battery cells 100 overlap up and down, and the colloid 102 is applied at a preset position on the edge of the lower battery cell 100 among two adjacent battery cells 100.

[0051] It should be noted that: Figure 2 The direction indicated by the solid arrow inclined to the lower left in is the blowing direction of the blowing assembly 20.

[0052] The blowing device proposed in the present application blows air through the blowing assembly 20 to blow the colloid 102 on the battery string between the overlapping parts of two adjacent adjacent battery cells 100, realizing the automatic application of the colloid 102 between the overlapping parts of the two battery cells 100.

[0054] the Y direction in

[0055] ), the air flow outlet 210 is opened on the air blowing part 21, and the first direction is perpendicular to the second direction; a blowing cavity communicating with the air flow outlet 210 is provided inside the air blowing part 21, the air inlet end of the blowing cavity is communicated with the gas supply member, and the gas supply member is configured to supply high-pressure gas into the blowing cavity; the high-pressure gas supplied by the gas supply member into the blowing cavity is blown out through the air flow outlet 210 to blow the colloid 102 at the edge of the lower battery cell 100 among two adjacent battery cells 100 into the overlapping part between two adjacent adjacent battery cells 100.

A second locking member 214 passes through the second installation hole and abuts against the corresponding connecting part 213 to fix the end part of the connecting part 213 on the corresponding installation part 211. When it is necessary to adjust the blowing angle of the blowing part 21, first loosen the second locking member 214 so that the connecting part 213 can rotate relative to the installation part 211, rotate the blowing part 21 to the preset angle, and then lock the connecting part 213 relative to the installation part 211 through the second locking member 214.

[0067] Through the cooperation of the connecting member 213, the mounting portion 211, the second adjustment hole and the second locking member 214, the blowing angle of the blowing portion 21 is adjusted, so that the blowing portion 21 is maintained at a suitable blowing angle, further improving the purging effect of the blowing assembly 20 on the colloid 102.

[0068] Please refer to Figure 2 and Figure 3 As shown, as an embodiment, the blowing device further includes a light box 30, and the light box 30 is configured to cure the colloid 102 blown into the overlapping portion between two adjacent battery cells 100.

[0069] Specifically, the colloid 102 is selected as a UV glue, and the light box 30 is a UV light box.

[0070] By providing the light box 30, the curing of the colloid 102 blown into the overlapping portion between two adjacent battery cells 100 is realized, providing a blowing device with both the functions of blowing and curing the colloid, with high integration.

[0071] As an embodiment, the blowing device further includes a bracket 40 and a mounting base 50. The light box 30 is assembled on the mounting base 50, the mounting base 50 is mounted on the bracket 40 in a liftable manner, and the mounting frame 10 is mounted on the light box 30.

[0072] Through the cooperation of the bracket 40, the mounting base 50 and the light box 30, the height adjustment of the light box 30 is realized.

[0080] For the second type of battery string (as shown in Figure 7 ), this type of battery string includes at least two groups of battery strings 60. Adjacent two groups of battery strings 60 are connected in series by a welding tape 101, that is, there is a gap between adjacent two groups of battery strings 60. Due to the existence of the gap, the distance between adjacent two rows of colloids on both sides of the gap is slightly larger than the distance between adjacent two rows of colloids in the same group of battery strings 60. Therefore, by controlling the two sets of air blowing assemblies to blow air alternately and adjusting the step distance of the conveying mechanism, it is possible to blow air on all colloids.
