[0024] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0025] In the present application, "a plurality of" refers to two or more. The "and / or" describes the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0026] Figure 1 The structure diagram of the busbar conveying device provided by the embodiments of the present application is shown in FIG. 1. The busbar 4 used in the photovoltaic industry is used for welding a battery string, and its size is relatively narrow. The feeding process needs to ensure that it is in a tension state. The bottom plate 1 in the present application is vertically arranged, and a support plate 2 and a material winding drum 3 are installed on the plate surface. The support plate 2 is installed on the bottom plate 1 by connecting rivets or other connecting members and is parallel to the bottom plate 1. A pair of feeding rollers 6 are installed on the upper part of the support plate 2, and a material tensioning roller 7 is installed on the lower part of the support plate 2. The pair of feeding rollers 6 on the upper part and the material tensioning roller 7 on the lower part form a Z-shaped feeding path from top to bottom and then upward, that is, the busbar 4 adopts a feeding mode from top to bottom and then upward.

[0027] In order to ensure that the transmission process of the busbar 4 can be found in time when it falls off, breaks or ends, a plurality of inductance sensors 9 can be installed on the bottom plate 1. The busbar 4 is made of metal material, and the inductance sensor 9 can detect in time and in real time, and can be found in time when the data is abnormal. This function needs to ensure that the inductance sensor 9 is near the conveying path, for example, on the conveying path between the material winding drum 3 and the feeding roller 6, to detect the busbar 4.

[0028] In some embodiments, the height of the material winding drum 3 is arranged on the bottom plate 1 between the feeding roller 6 and the material tensioning roller 7; and at least one guide roller 5 is arranged above the bottom plate 1 of the material winding drum 3. The busbar 4 passes through the guide roller 5 upward and then is sent into the feeding roller 6.

[0029] In normal operation, the busbar 4 is conveyed from the material winding drum 3 to one of the feeding rollers 6, then passes through the material tensioning roller 7 downward, and then is sent into the other feeding roller 6 upward after passing through the material tensioning roller 7, and is output.

[0030] Considering the toughness of the busbar 4, it may not be possible to ensure normal transmission if the position of the material tensioning roller 7 is fixed. Therefore, the material tensioning roller 7 is arranged in a gravity stretching mode in the present application, that is, the busbar 4 is tensioned in a completely gravity sagging mode.

[0031] Figure 2is another structural diagram of the busbar conveying device from another perspective, a drive motor 31 is arranged on the bottom plate 1 at the back of the winding drum 3, and the drive motor 31 controls the winding drum 3 to wind and unwind the material through a transmission assembly. In order to facilitate the installation of the feeding roller 6, the support plate 2 is designed in a T shape, including a horizontal plate 21 at the top and a vertical plate 22 below the horizontal plate 21. A pair of feeding rollers 6 are respectively fixedly installed at the two ends of the horizontal plate 21, and the drawing roller 7 is arranged at the bottom end of the vertical plate 22. Figure 3 is a front view of the busbar conveying device.

[0032] Figure 4 is Figure 1 For the convenience of description, the first feeding roller is called the first feeding roller, and the second feeding roller is called the second feeding roller. A sliding assembly 8 is arranged on the vertical plate 22, and the drawing roller 7 is slidingly arranged on the sliding assembly 8 and slides in the vertical direction.

[0033] In a feasible implementation, the sliding assembly 8 includes a sliding rail 81 and a sliding block 82, the sliding rail 81 is vertically installed on the vertical plate 22, and the drawing roller 7 is installed on the sliding block 82. During the conveying process, after the busbar 4 passes through the first feeding roller, the material is vertically stretched downward, and is naturally drawn tight under the action of the gravity of the drawing roller 7, and then passes through the second feeding roller upward and is vertically stretched downward. This process can ensure that the tightness of the busbar 4 is controllable, and the busbar 4 will not be broken due to excessive tightness. In theory, as long as the stress analysis is designed well, the drawing roller 7 can be maintained at a certain specific height or at the bottom.

[0034] In some other embodiments, in order to enable the busbar 4 to be smoothly conveyed to the feeding roller 6 after being sent out by the winding drum 3, at least two guide rollers 5 are installed on the bottom plate 1, Figure 3 In the figure, the first guide roller 5 is arranged directly above the winding drum 3, and the other guide roller 5 is arranged at the same height as the feeding roller 6, so as to horizontally send the busbar 4 to the feeding roller 6. In order to ensure that the busbar 4 will not cause other secondary damage due to breakage and winding, a baffle 10 can also be vertically installed on the bottom plate 1 above the guide roller 5 for protection. Further setting, a pressing rod 11 can also be arranged above the busbar 4 between the guide roller 5 and the feeding roller 6, and a pressing head is arranged on the feeding roller 6, so as to ensure that the busbar 4 will not jump out of the roller.

[0035] In summary, the conveying path of the busbar in the present application is designed in a Z-shaped route from top to bottom and then upward, the busbar is pulled by the two symmetrical feeding rollers on the upper part of the support plate, and the busbar is drawn tight by the drawing roller at the bottom of the support plate. Further, an inductive sensor can be installed on the conveying path between the winding drum and the feeding roller to monitor the busbar.
