[0002] Photovoltaic welding ribbon, also known as tinned copper ribbon or tin-coated copper ribbon, is a branch current ribbon and interconnection strip. It is used to connect the solar cells of photovoltaic modules and plays an important role in conductive collection. The welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module. Therefore, the photovoltaic welding ribbon needs to be protected by protective devices during transportation.

[0003] At present, photovoltaic welding ribbons are generally rolled up on load-bearing protective rollers to achieve picking up and protection; however, the existing photovoltaic welding ribbon protection devices have the following shortcomings:

[0004] 1. There is no protective measure in the middle of the roller, which causes the photovoltaic welding ribbon wound on the outer circumference of the roller to be easily scratched by foreign objects, affecting its use. It is inconvenient to add protective measures on the roller to protect the photovoltaic welding ribbon.

There are no lifting and grasping measures on the load-bearing protective roller of the photovoltaic welding ribbon, which makes the lifting and moving process of the welding ribbon roller difficult, and it is not convenient to install lifting and grasping measures on the welding ribbon roller for grasping and carrying.

When the device body 1 is carried and moved, the carrying gripping rod 3 is turned forward 90 degrees and then held by the gripping rod of the carrying gripping rod 3 to lift and move the device body 1. Figure 1 When the weld tape protective tube 6 shown is disassembled, the protective limiting column 5 is rotated by a tool to threadably engage with the weld tape carrying roller 2, so that the protective limiting column 5 moves forward through the threaded engagement to disengage from the threaded hole of the weld tape carrying roller 2, and then the weld tape protective tube 6 is moved upward to disengage from the outside of the weld tape carrying roller 2; when the weld tape carrying roller 2 winds the photovoltaic weld tape, the end of the photovoltaic weld tape is inserted into the strip hole 210 of the weld tape carrying roller 2, and the weld tape fixing button 4 is rotated to threadably engage with the weld tape carrying roller 2, so that the weld tape fixing button 4 is pressed down to press the end of the photovoltaic weld tape through the threaded engagement, and the photovoltaic weld tape is fixed on the weld tape carrying roller 2 through the weld tape fixing button 4, and then the weld tape carrying roller 2 is rotated to wind the photovoltaic weld tape.

[0048] Compared with the prior art, the utility model has the following beneficial effects:

[0049] The convenient lifting and grasping rod 3 is installed on the welding strip carrying roller 2 for flipping, standing up and laying flat, which makes it convenient to lift and move the device body 1 through the lifting and grasping rod 3, thereby solving the problem that there is no lifting and grasping measure on the carrying and protective roller of the photovoltaic welding strip, which makes the lifting and moving process of the welding strip roller more difficult and it is inconvenient to add lifting and grasping measures to the welding strip roller for grasping and carrying.

[0050] The welding tape protection tube 6 is conveniently mounted on the outside of the welding tape carrying roller 2 and limited by the protection limit column 5, so that the photovoltaic welding tape wound on the welding tape carrying roller 2 can be conveniently protected by the welding tape protection tube 6, which solves the problem that there is no protective measure in the middle of the roller, resulting in the photovoltaic welding tape wound on the outer circumference of the roller being easily scratched by foreign objects and affecting its use, and it is inconvenient to add protective measures on the roller to protect the photovoltaic welding tape.
