[0002] Driven by global demand for carbon neutrality, the scale of clean energy, including photovoltaics, continues to rise. The demand for unmanned operation throughout the entire lifecycle of photovoltaic power plants is clear, and the market prospects are promising. Currently, domestic photovoltaic panel installations mostly rely on bolts and nuts for fastening, requiring manual tightening of multiple fasteners, which is cumbersome and inefficient. Furthermore, bolt and nut tightening often occurs in confined spaces, making it difficult to operate and incurring high labor costs.

[0003] In addition, since the photovoltaic panels are installed on a ground with low flatness and the photovoltaic panel trusses will undergo large deformation during the installation process, the positions of the pre-processed mounting holes on the trusses will change, which will have a great impact on the installation and fixation of the photovoltaic panels. Summary of the Invention

[0017] S2, the motor shaft of the No. 1 rotating motor 3-1 attracts the drill bit and drives the drill bit to drill holes at all the locations to be installed on the photovoltaic panel installation truss. After the drilling is completed, the drill bit stops attracting;

[0018] S3. Place the photovoltaic panel on the upper surface of the hole drilled in S2. The motor shaft of the No. 1 rotating motor 3-1 attracts the screwdriver. The screwdriver attracts the bolt 3-6 and moves it above the photovoltaic panel, directly above the drilled hole.

The No. 2 rotating motor 3-2 has a torque of not less than 5 Nm.

[0032] One side of the connecting plate 3-5 is fixedly connected to the main body of the adsorption system 4, and the No. 1 rotating motor 3-1 and the No. 2 rotating motor 3-2 are fixed on the connecting plate 3-5, and the motor shaft of the No. 1 rotating motor 3-1 and the motor shaft of the No. 2 rotating motor 3-2 are axially perpendicular; the motor shaft of the No. 2 rotating motor 3-2 is fixedly connected to the nut mounting bracket 3-3, which can drive the nut mounting bracket 3-3 to rotate. The nut mounting bracket 3-3 is provided with a through slot with one side passing therethrough, and the nut can be placed on the magnetic suction cup of the through slot, and the width of the through slot can enable the nut to slide in the through slot; under the drilling working condition, the rotating nut mounting bracket 3-3 is in a non-interference state; under the fixed locking working condition, the rotating nut mounting bracket 3-3 is in a working state.

[0033] When performing the drilling operation, the No. 2 rotating motor 3-2 rotates the nut mounting bracket 3-3 to a non-interference state, that is, away from the bottom of the No. 1 rotating motor 3-1; when performing the locking operation, the nut mounting bracket 3-3 is turned to the working state, and the nut 3-7 is placed on the through groove directly below the motor shaft of the No. 1 rotating motor 3-1. The motor shaft of the No. 1 rotating motor 3-1 is magnetic and can be extended.

[0034] In this embodiment, a nut magnetic chuck 3-4 is provided on the through slot just below the motor shaft of the No. 1 rotating motor 3-1, which is used to absorb the nut 3-7 and supply the nut for assembly; in addition, it prevents the nut from falling off when the nut mounting bracket 3-3 is in a non-interference state.

[0035] With the cooperation of the robot, this embodiment drills holes at designated locations and automatically tightens nuts, replacing the complicated and tedious manual fixing and locking work during the actual installation process, and avoiding problems such as inaccurate hole positions and excessive assembly stress caused by deformation of the photovoltaic panel truss during the installation process.

[0039] (2) The motor shaft of the No. 1 rotating motor 3-1 attracts the drill bit and, under the guidance of the visual recognition and positioning system, drives the drill bit to drill holes on the photovoltaic panel mounting truss. After the drilling is completed, the drill bit stops attracting the drill bit;

[0040] (3) Place the photovoltaic panel on the upper surface of the punched hole, and the motor shaft of the No. 1 rotating motor 3-1 attracts the screwdriver, which attracts the bolt 3-6 and moves to the top of the photovoltaic panel and directly above the punched hole;

[0041] (4) Issue a locking task, the No. 1 rotating motor 3-1 absorbs the screwdriver, screws it to the absorption bolt, lowers the nut mounting bracket 3-3, and adjusts it to the working state: the nut is placed on the nut mounting bracket 3-3, the motor shaft of the No. 2 rotating motor 3-2 drives the nut mounting bracket 3-3 to rotate, so that the nut 3-7 is located directly below the punched hole, the motor shaft of the No. 1 rotating motor 3-1 rotates and extends, driving the bolt 3-6 absorbed by the screwdriver to rotate at the punching position of the photovoltaic panel 5 and move downward until the bolt 3-6 is tightened, so that the bolt 3-6 passes through the photovoltaic panel 5 and is locked with the nut below;

[0042] (5) After the nut is tightened, the punching and locking mechanism is moved horizontally along the through-slot direction and leaves the photovoltaic panel installation truss.

[0043] The automated photovoltaic panel placement system of this embodiment automatically generates a placement plan based on task requirements, plans the movement path of the omnidirectional transport system 8, and the installation steps for the photovoltaic panels 5.
