[0055] Refer to Figure 1 and Figure 3, an embodiment of the present utility model provides an infrared welding light box, comprising: a light box bracket 10 and an infrared welding assembly 20, the infrared welding assembly 20 is installed on the light box bracket 10, the infrared welding assembly 20 includes a preheating lamp tube 202, a welding lamp tube 201 and a lamp tube installation assembly 203, the welding lamp tube 201 and the preheating lamp tube 202 are respectively installed on the lamp tube installation assembly 203, the preheating lamp tube 202 is used to preheat the object to be welded 50, and the welding lamp tube 201 is used to heat and weld the preheated object to be welded 50.

[0056] As Figure 1 shown, multiple welding lamp tubes 201 may be provided. In this way, the welding lamp tubes 201 can heat and weld the object to be welded 50 below them.

In this way, before the welding lamp tube 201 is used to heat and weld the solar cell 50, the preheating lamp tube 202 can preheat the solar cell 50 in a low-power manner and heat the solar cell 50 to a certain temperature. In this way, after the solar cell 50 reaches the welding lamp tube 201, the welding lamp tube 201 heats the silver grid and solder strip of the cell, which can accelerate the melting of the silver grid and solder strip of the solar cell 50 and realize the welding of the solder strip on the solar cell 50 after cooling and solidification.

[0057] As Figure 3 shown, in an embodiment of the present utility model, the lamp tube installation assembly 203 includes: a lamp tube installation plate 2031, and the welding lamp tube 201 is installed on the lamp tube installation plate 2031. Among them, lamp tube clamping heads 2032 are respectively provided at both ends of the lamp tube installation plate 2031, and the welding lamp tube 201 is installed on the lamp tube installation plate 2031 through the lamp tube clamping heads 2032. The two ends of the welding lamp tube 201 can be clamped by the lamp tube clamping heads 2032, so as to facilitate the installation and disassembly of the welding lamp tube 201. In addition, each preheating lamp tube 202 can be clamped by two lamp tube clamping heads 2032, so as to facilitate the installation and disassembly of the preheating lamp tube 202.

[0058] Refer to Figure 2 and Figure 3, the lamp tube mounting assembly 203 further includes: a lamp tube adjusting plate 2033, the lamp tube adjusting plate 2033 is fixedly connected to the lamp box bracket 10 relatively, and a lamp post adjusting through slot 20331 is provided on the lamp tube adjusting plate 2033; a plurality of welded lamp tubes 201 and lamp tube mounting plates 2031 are respectively provided, and the lamp tube mounting plate 2031 is adjustably mounted at the lamp post adjusting through slot 20331.

[0059] As Figure 2 and Figure 3 shown in, since the lamp post adjusting through slot 20331 is provided on the lamp tube adjusting plate 2033, and two lamp tube adjusting plates 2033 may be provided. In this way, both ends of each lamp tube mounting plate 2031 are respectively mounted on the lamp tube adjusting plate 2033 through the lamp post adjusting through slot 20331.

The preheating lamp tube 202 preheats the battery wafer in advance at a low power, and the welded lamp tube 201 heats the silver grid and the welding tape of the battery wafer according to the arrangement of the battery wafer pattern, making the welding of the solar cell panel more accurate.

[0060] Refer to Figure 3 and Figure 4 , the lamp tube mounting assembly 203 further includes: a light shielding plate 2034, two light shielding plates 2034 are provided, the light shielding plate 2034 is fixedly connected to the lamp box bracket 10 relatively, and the welded lamp tube 201 is located between the inner sides of the two light shielding plates 2034; one or more preheating lamp tubes 202 are provided, and are located outside the two light shielding plates 2034.

The uniformly distributed axial flow fans 401 continuously blow air to dissipate heat inside the light box, forming a stable and uniform temperature field in the light box with the heated lamp tube and the welding bottom plate heated from below. An air extraction pipe is provided at the air inlet of the axial flow fan 401, and the air extraction pipe is connected to the constant temperature environment outside the equipment to ensure that the temperature of the heat dissipation air delivered by the axial flow fan 401 into the light box is constant and controllable, avoiding heat accumulation after long-term welding and the rise of the temperature inside the equipment affecting the heat dissipation effect.

[0068] Referring to Figure 3 and Figure 4 , an exhaust pipe 101 is further provided on the light box bracket 10. The exhaust pipe 101 is used to be connected to the extraction fan 401 to externally discharge the hot air and flux crystallization inside the light box bracket 10.
