DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0018] like Figure 1-2 As shown, a solar liner center seam welding machine includes a machine base 1, a column 2 is arranged on the machine base 1, at least two liner positioning members 3 are arranged on the column 2, the liner positioning member 3 includes a lower support member 32 and an upper positioning member 31, the lower support member 32 is fixed on the column 2, the upper positioning member 31 is arranged above the lower support member 32 and the upper positioning member 31 is hinged to the column, a long strip through hole 33 matching the center seam 11 is arranged on the top of the upper positioning member 31, a cavity for accommodating the solar liner 10 is formed between the lower support member 32 and the upper positioning member 31; a welding gun 4 is arranged above the upper positioning member 31.

[0019] The inner tank positioning member 3 in the utility model ensures the stability of the solar energy during the welding process and ensures the accuracy of welding. When in use, the solar tank to be welded is placed in the cavity of the inner tank positioning member 3, so that the middle seam of the inner tank is arranged opposite to the long strip through hole 33, and the welding gun 4 is turned on to weld the middle seam of the inner tank. The setting of the long strip through hole 33 can just expose the middle seam of the solar tank, which provides convenience for welding operation.

[0020] Specifically, two groups of liner positioning members 3 are arranged on the column 2 of the utility model.

[0021] Furthermore, the bottom of the column 2 is fixed to the mounting plate 5, and the mounting plate 5 is fixed to the base 1. The arrangement of the mounting plate 5 enables the column 2 to obtain more stable support from the base 1, thereby enhancing the overall stability and providing a reliable platform for welding operations.

[0022] Furthermore, the mounting plate 5 is provided with a waist-shaped hole (not shown in the figure), the waist-shaped hole is arranged along the axial direction of the solar energy inner tank, and a fixing bolt 6 is arranged in the waist-shaped hole, and the fixing bolt 6 is fixed to the base 1. The setting of the waist-shaped hole allows the position of the column 2 to be fine-tuned to adapt to inner tanks of different lengths and specifications, while ensuring the precise positioning of the inner tank during the welding process.

[0023] Furthermore, both ends of the lower support member 32 are fixedly connected to the column 2 by bolts 7. The lower support member 32 provides a stable support surface for the inner container, ensuring that the inner container will not shake or shift during the welding process.

[0024] Furthermore, the upper positioning member 31 includes a first hinge portion 311 and a second hinge portion 312, wherein the first hinge portion 311 is rotatably connected to the column 2 via a first hinge shaft 34, and the second hinge portion 312 is rotatably connected to the column 2 via a second hinge shaft 35. The first hinge portion 311 and the second hinge portion 312 are rotated to place the inner liner on the lower support member 32, and the first hinge portion 311 and the second hinge portion 312 are rotated again to place the first hinge portion 311 and the second hinge portion 312 on the inner liner, and then the subsequent welding operation can be started; after the welding is completed, the first hinge portion 311 and the second hinge portion 312 are rotated to take out the inner liner, and a new inner liner is put in for welding.

[0025] Furthermore, the first hinged portion 311 is fixed to the lower support member 32 by a first locking bolt 36, and the second hinged portion 312 is fixed to the lower support member 32 by a second locking bolt 37. During the welding process, the inner liner is adjusted into position to expose the middle seam, and then the first locking bolt 36 and the second locking bolt 37 are used to fix the inner liner, ensuring that the inner liner can remain stable after being adjusted into position, preventing accidental movement during the welding process, thereby ensuring the quality and accuracy of welding.

[0026] Furthermore, the top of the welding gun 4 is connected to a slide block 8, and the slide block 8 is slidably connected to a slide groove (not shown in the figure), and the slide groove is arranged on the machine base 1. The slide block 8 is driven to move by a pneumatic cylinder 9. The welding gun 4 can slide flexibly along the slide groove, ensuring that the welding gun 4 always moves along the middle seam of the inner liner to achieve precise welding. At the same time, the slide block 8 is driven by the pneumatic cylinder 9, which greatly improves the automation degree and work efficiency of welding and reduces the labor intensity of the operator.

[0027] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
