It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0039] Embodiment 1:

[0040] This embodiment provides a double-row module middle partition welding tool, including:

[0041] Welding platform 1;

[0042] A middle diaphragm plate positioning mechanism 2, wherein the middle diaphragm plate positioning mechanism 2 is used to fix the middle diaphragm plate 21 and the end plate 22 to be welded;

[0043] A copper nozzle mechanism 3, wherein the copper nozzle mechanism 3 is installed on the welding platform 1, and the copper nozzle mechanism 3 is provided with a blowing nozzle 31 for blowing protective gas to the welding position;

[0044] A dust suction mechanism 4, which is installed on the welding platform 1 and is used to suck away welding slag at the welding location;

[0045] Wherein, a lifting mechanism is provided on the welding platform 1, and the lifting mechanism is used to drive the middle partition plate positioning mechanism 2 to rise along the Z direction and press the middle partition plate 21 and the copper nozzle mechanism 3 in the Z direction.

[0046] In the present technical solution, a hollow structure for accommodating the middle partition 21 and the end plate 22 is provided on the welding platform 1, and a lifting mechanism is provided in the welding platform 1. The lifting mechanism can be any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, or other devices that can drive the middle partition positioning mechanism 2 to rise and fall along the Z direction. The middle partition 21 and the end plate 22 are installed on the middle partition positioning mechanism 2 by manual operation, and then the middle partition positioning mechanism 2 enters the welding platform 1 along the assembly line, and the lifting mechanism lifts the middle partition positioning mechanism 2 and moves it along the Z direction, so that the middle partition 21 and the end plate 22 are located in the hollow structure of the welding platform 1, and at the same time, the middle partition 21 and the end plate 22 are pressed and fixed in the Z direction by the copper nozzle mechanism 3 and the middle partition positioning mechanism 2, so as to realize the rapid positioning between the middle partition 21 and the end plate 22, and facilitate the staff to weld the middle partition 21 and the end plate 22, thereby improving the work efficiency.

[0047] When the middle partition plate 21 and the end plate 22 are welded, a protective gas is blown into the welding point through the blowing nozzle 31. The protective gas can be nitrogen, and the overall length of the blowing nozzle 31 is designed according to the length of the weld to ensure that the welding point is blown with protective gas, thereby ensuring the beautiful appearance of the welding point.

[0048] In addition, when the middle partition plate 21 and the end plate 22 are welded, the dust suction mechanism 4 sucks away all the welding slag at the welding point. Removing the welding slag can ensure the complete penetration of the welding joint, improve the welding quality and connection strength, make the weld more neat, and improve the welding appearance quality.

[0049] Embodiment 2:

[0050] This embodiment provides a double-row module middle partition welding tool, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0051] Furthermore, the copper nozzle mechanism 3 includes:

[0052] A mounting plate 32, wherein the mounting plate 32 is mounted on the welding platform 1;

[0053] A pressure plate copper nozzle 33, the blowing nozzle 31 is arranged on the pressure plate copper nozzle 33, and a pipe 34 connected to the blowing nozzle 31 is arranged on the pressure plate copper nozzle 33;

[0054] The pressure plate copper nozzle 33 is connected to the lower part of the mounting plate 32 in the Z direction.

[0055] In the present technical solution, the copper nozzle mechanism 3 is fixed on the welding platform 1 as a whole through the mounting plate 32, and the pressure plate copper nozzle 33 is connected to the Z-direction downward of the mounting plate 32. When the lifting mechanism drives the middle partition positioning mechanism 2 to rise along the Z-direction to the bottom of the pressure plate copper nozzle 33, the middle partition 21 and the T-shaped end plate 22 on the middle partition positioning mechanism 2 are located between the pressure plate copper nozzle 33 and the middle partition positioning mechanism 2 and are clamped and fixed, which is convenient for welding operations.

[0056] The connecting pipe 34 on the copper nozzle 33 of the pressing plate is connected to the air source, and the air source delivers protective gas to the blowing nozzle 31 of the copper nozzle 33 of the pressing plate through the connecting pipe 34, and then the protective gas is blown toward the welding point of the middle partition 21 and the T-shaped end plate 22 through the blowing nozzle 31, so as to ensure the beauty of the welding point; and the blowing nozzle 31 is connected to the air source through the connecting pipe 34, while ensuring sufficient airflow, it can also control the stability of the output airflow of the blowing nozzle, avoiding unnecessary risks caused by excessive or insufficient airflow.

[0061] In the present technical solution, when the lifting mechanism drives the middle-end plate 22 positioning mechanism to rise in the Z direction, the middle-end plate 22 on the middle-end plate 22 positioning mechanism abuts against the pressure plate copper nozzle 33. Since the mounting plate 32 is fixed on the welding platform 1, the elastic member 35 is squeezed to generate elastic force acting on the pressure plate copper nozzle 33, so that the pressure plate copper nozzle 33 and the middle-end plate 22 fit tightly, so that the middle-end plate 22 and the end plate 22 can be pressed more tightly, avoiding the displacement between the middle-end plate 22 and the end plate 22 to affect the welding.

Through this structural design, the expansion and contraction stability of the spring is improved, and the spring is prevented from being offset during the expansion and contraction process, making the expansion and contraction of the spring more stable and smooth, thereby ensuring that the middle end plate 22 and the end plate 22 can be pressed tightly.
