Technical Field

[0001] This patent relates to the technical field of busbars for photovoltaic modules, and specifically to a busbar conveying device for photovoltaic modules. Background Art

[0002] A photovoltaic module is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Since it has no moving parts, it can be operated for a long time without causing any loss. The busbars of the photovoltaic module need to be transported. Traditionally, they are placed on the belt body of a conveyor belt, and then driven by a feed motor until they enter the bottom of the welding machine and stop. However, the current busbar conveying device of the photovoltaic module has a problem of deviation in the conveying direction during the conveying process because the busbars of the photovoltaic module are narrow and thin.

The rotating structures 10 are symmetrically distributed on both sides with the center line of the driven gear roller 3 as the center.
