[0025] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0026] like Figure 1 As shown, an embodiment of the present disclosure provides a light box device for a stringer, which is used to sequentially heat each soldering ribbon area arranged along a preset direction on a battery string. The light box device for a stringer includes: a light box body 10 and an air guide plate structure 20. The light box body 10 includes a box body 11, an air supply device 12 disposed at the top of the box body 11, and a lamp tube 13 disposed within the box body 11. An air inlet 111a communicating with the air supply device 12 is disposed at a position on the top of the box body 11 corresponding to the air supply device 12, and an air outlet 213 is disposed at the bottom of the box body 11. The air guide plate structure 20 includes a connecting plate 21 connected to the bottom of the box body 11 and an air guide plate 22 connected to the connecting plate 21. In the conveying direction of the battery string, the air guide plate 22 is disposed downstream of the connecting plate 21 and is used to guide the hot air discharged from the air outlet 213 toward the upstream side.

[0027] In the light box device for the string welding machine provided in this embodiment, an air guide plate structure 20 is provided at the bottom of the light box body 10. The air guide plate 22 of the air guide plate structure 20 can guide the hot air discharged from the exhaust port 213 to the upstream side, thereby avoiding the hot air heating the soldering area of the next group of battery cells in advance, causing the soldering area of the next group of battery cells to melt tin in advance and cause cold soldering, thereby improving the product yield.

[0028] In one embodiment, the box body 11 includes a top plate 111 and a side plate 112 arranged around the top plate 111, the air supply device 12 is installed on the top plate 111, the air inlet 111a is arranged on the top plate 111, the lamp tube 13 is connected to the side plate 112 through the mounting plate 14, the connecting plate 21 closes the lower opening of the box body 11, and the exhaust port 213 is arranged on the connecting plate 21. In this way, the bottom plate of the box body 11 is formed by utilizing the air guide plate structure 20, the structure is simpler, the air flow path is reduced, and the heating efficiency is improved.

[0029] In one embodiment, the air guide plate 22 is formed by bending a portion of the downstream side of the connecting plate 21 , thereby further simplifying the structure.

[0030] In one embodiment, Figure 2 and Figure 3 As shown, the connecting plate 21 and the air guide plate 22 are rotatably connected via a rotating shaft assembly, and the rotating shaft assembly includes a main shaft 23 and a damping sleeve 24 sleeved on the main shaft 23. The connecting plate 21 and the air guide plate 22 are both rotatably connected to the damping sleeve 24 and are kept in fixed position by the damping of the damping sleeve 24. In this way, a suitable angle of the air guide plate 22 can be selected according to actual needs, thereby avoiding the hot air from heating the solder strip area of the next group of battery cells in advance, causing the solder strip area of the next group of battery cells to melt tin in advance and cause cold solder joints, and ensuring that sufficient hot air is used to heat the solder strip area of the current battery cell.

[0031] In one embodiment, the end surface of the connecting plate 21 facing the air guide plate 22 includes a first limiting surface 211 and a second limiting surface 212, and the end surface of the air guide plate 22 facing the connecting plate 21 includes a third limiting surface 221 opposite to the first limiting surface 211 and a fourth limiting surface 222 opposite to the second limiting surface 212.

[0032] The air deflector 22 has a first rotation limit position and a second rotation limit position. In the first rotation limit position, the first limiting surface 211 abuts the third limiting surface 221. In the second rotation limit position, the second limiting surface 212 abuts the fourth limiting surface 222. The first limiting surface 211, the second limiting surface 212, the third limiting surface 221, and the fourth limiting surface 222 are arranged to limit the rotation position of the air deflector 22, thereby preventing the air deflector 22 from rotating excessively.

[0033] In one embodiment, the light box device for the string welding machine also includes an elastic closing structure 25, which is used to fill the space between the second limiting surface 212 and the fourth limiting surface 222, thereby preventing the air flow from entering the space between the second limiting surface 212 and the fourth limiting surface 222 and causing the loss of hot air flow.

[0034] In one embodiment, the elastic sealing structure 25 includes a first filling portion 251 and a second filling portion 252 connected to each other. The first filling portion 251 is located between the second limiting surface 212 and the fourth limiting surface 222, and the first filling portion 251 abuts against the damping sleeve 24. The second filling portion 252 covers the air guide plate 22 and part of the side surface of the connecting plate 21.

[0035] In one embodiment, the outer surface of the second filling portion 252 is smoothly connected to the side of the wind guide plate 22, and the outer surface of the second filling portion 252 is smoothly connected to the side of the connecting plate 21, thereby further reducing wind resistance.

[0036] In one embodiment, Figure 4 As shown, a dust adsorption layer 30 is provided on the side of the air guide plate structure 20 facing the battery string, which can adsorb dust in the air flow to prevent dust from entering the welding strip area with the air flow and affecting the welding quality.

[0037] In the light box device for the string welding machine provided in this embodiment, an air guide plate structure 20 is provided at the bottom of the light box body 10. The air guide plate 22 of the air guide plate structure 20 can guide the hot air discharged from the exhaust port 213 to the upstream side, thereby avoiding the hot air heating the soldering area of the next group of battery cells in advance, causing the soldering area of the next group of battery cells to melt tin in advance and cause cold soldering, thereby improving the product yield.

[0038] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the scope of patent protection of the present invention shall be defined by the claims.
