Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to an anti-flipping photovoltaic welding belt delivery structure. Background Art

[0002] With the large-scale application of photovoltaic cells, the welding of photovoltaic ribbons is almost entirely completed by automated equipment. During the process of winding and unwinding the ribbon, the ribbon is prone to flipping, and the flipped part will bulge, which can easily cause poor welding and bulging and broken battery cells. Therefore, it is necessary to invent a new ribbon delivery structure to avoid flipping. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention attempts to overcome the above defects, and thus provides an anti-flipping photovoltaic welding ribbon delivery structure, which prevents the welding ribbon from flipping by tightly attaching the welding ribbon to the auxiliary bonding tape.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: an anti-flip photovoltaic welding tape shipping structure, including a welding tape and an auxiliary bonding tape, the welding tape is tightly attached to the auxiliary bonding tape, the material of the auxiliary bonding tape is PET or PE, the welding tape is bonded to the auxiliary bonding tape by hot roller pressing, and the side of the auxiliary bonding tape that is not bonded to the welding tape is affixed with bright aluminum foil, and the outward side of the aluminum foil is painted with a logo color.

[0005] Furthermore, the thickness of the auxiliary bonding tape is 0.5-3 times the thickness of the welding tape.

[0006] Furthermore, the width of the auxiliary bonding tape is 1.5-3 times the width of the welding tape.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] PET and PE are transparent materials, with bright aluminum foil attached to one side and photovoltaic welding tape attached to the other side. The reflection of the bright aluminum foil facilitates machine vision to check whether the width of the welding tape has changed, and then judge whether the welding tape has flipped. The auxiliary bonding tape can enhance the anti-flip performance of the structure, making it difficult to flip during the winding and unwinding process. The outer side of the aluminum foil is painted with a logo color to indicate whether the shipping structure has flipped. The welding tape is attached to PET and PE tapes by hot roller pressing, which is convenient for separating the welding tape when using it. At the same time, the auxiliary bonding tape can be reused to reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

The side of the PET tape 2 that is not bonded to the welding tape is affixed with a bright aluminum foil 3. The side of the aluminum foil 3 facing outward is painted with a logo color. The thickness of the auxiliary bonding tape is 0.5-3 times the thickness of the welding tape, and the width of the auxiliary bonding tape is 1.5-3 times the width of the welding tape.

[0013] Embodiment 2, the utility model provides an anti-flip photovoltaic welding tape delivery structure, including a welding tape and an auxiliary bonding tape, the welding tape is tightly attached to the auxiliary bonding tape, the material of the auxiliary bonding tape is PE, the welding tape is bonded to the PE tape by hot roller pressing, the side of the PE tape that is not bonded to the welding tape is affixed with a bright aluminum foil 3, and the side of the aluminum foil 3 facing outwards is painted with a marking color, the thickness of the auxiliary bonding tape is 0.5-3 times the thickness of the welding tape, and the width of the auxiliary bonding tape is 1.5-3 times the width of the welding tape.

[0014] Working principle: PET and PE are transparent materials, with bright aluminum foil 3 attached to one side and photovoltaic welding tape 1 attached to the other side. The reflection of the bright aluminum foil 3 facilitates machine vision to check whether the width of the welding tape has changed, and then judge whether the welding tape has flipped. The auxiliary bonding tape can enhance the anti-flip performance of the structure, making it difficult to flip during the winding and unwinding process. The outer side of the aluminum foil 3 is painted with a marking color to indicate whether the shipping structure has flipped.
