[0043] In this embodiment, if Figure 5 As shown, the clamping device 6 includes a support frame 61 and a first pneumatic clamp 62, a second pneumatic clamp 63, a limit assembly 64 and a positioning assembly 65 arranged thereon; the positioning assembly 65 is located between the first pneumatic clamp 62 and the limit assembly 64, and both are arranged corresponding to the box body of the junction box, and the second pneumatic clamp 63 is arranged corresponding to the cable of the junction box.

[0044] Both the positive and negative terminal boxes include a box body and cables.

[0045] Specifically, Figure 6 As shown, the limiting assembly 64 includes a first cylinder 641 and a limiting plate 642 arranged thereon, and the limiting plate 642 is driven by the first cylinder 641 to move toward the first pneumatic clamp 62; the first pneumatic clamp 62 includes a first clamp cylinder 621 and an L-shaped clamp 622 arranged thereon, and two L-shaped clamps 622 are arranged in parallel. The two L-shaped clamps 622 move relative to each other along the length direction of the limiting plate 642 under the drive of the first clamp cylinder 621.

[0046] The positioning assembly 65 includes a second cylinder 651 and a positioning rod 652 arranged thereon. The second cylinder 651 drives the positioning rod 652 to move in a direction perpendicular to the running direction of the limit plate 642 and the L-shaped clamp plate 622. A claw 652a is arranged at the end of the positioning rod 652 away from the second cylinder 651. The claw 652a is located between the two L-shaped clamp plates 622 and the limit plate 642, and cooperates with the wire hole of the junction box.

[0047] In the specific clamping process of the junction box body, first adjust the angle of the clamping device 6 to align the positioning rod 652 with the wire hole on the box body, and drive the positioning rod 652 through the second cylinder 651 to make the claw 652a at its end engage with the wire hole to realize the positioning of the box body and the subsequent clamping operation; then drive the two L-shaped clamping plates 622 arranged thereon through the first clamping claw cylinder 621 to clamp and fix the long sides of the box body on both sides, and then drive the limit plate 642 through the first cylinder 641 to press the end of the box body away from the cable, remove the three sides of the box body where the cable is provided, and clamp and fix the box body, thereby completing the clamping and fixation of the box body.

[0048] In this embodiment, the support frame 61 includes a connecting plate 611 and a mounting plate 612 arranged in parallel, and the mounting plate 612 is connected to the connecting plate 611 through a guide column 613; the connecting plate 611 is connected to the free end of the robotic arm 51 through a connecting shaft 52, and the mounting plate 612 is slidably connected to one end of the guide column 613, and a compression spring 614 is provided on the outer ring of the guide column 613.

[0049] The second cylinder 651 is arranged on the mounting plate 612 and is located between the connecting plate 611 and the mounting plate 612.

The positioning rod 652 is arranged in the limiting hole 653a and is slidably connected thereto.

[0050] Furthermore, the first clamping cylinder 621 and the first cylinder 641 are respectively fixed on the side of the mounting plate 612 away from the connecting plate 611 through the first support plate 623 and the second support plate 643; the second pneumatic clamp 63 includes a second clamping cylinder 631 and a cable clamp 632 arranged thereon, the cable clamp 632 is located on the side of the L-shaped clamp 622 away from the limiting plate 642, and the second clamping cylinder 631 is fixed on one side of the mounting plate 612 through the third support plate 633.

[0051] Each cylinder that performs the clamping operation on the junction box is installed on the mounting plate 612 of the support frame 61. In the process of pressing the junction box against the surface of the photovoltaic panel, the mounting plate 612 moves toward the connecting plate 611 after being subjected to force, and recovers under the action of the compression spring 614 after the installation is completed, thereby avoiding excessive pressure on the surface of the photovoltaic panel during the installation process, which may cause damage to the photovoltaic panel.

[0053] The first camera 71 and the second camera 81 monitor the transport status of the junction box and the photovoltaic panel in real time, so as to facilitate the accurate grasping of the junction box and the precise docking with the bus bar on the photovoltaic panel.

[0054] In this embodiment, the plurality of transmission belts 31 are powered by a first power device 32 , and the transmission belt 41 is powered by a second power device 42 disposed on the second bracket 2 .
