[0017] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, an automated bolt tightening construction equipment for photovoltaic module connections is movable and is provided with a robotic arm and a clamping device and a bolt tightening tool. The equipment has a built-in centralized control system, an automatic navigation and positioning system, and a visual recognition system. The centralized control system is respectively communicated with the automatic navigation and positioning system, the visual recognition system, the robotic arm and the clamping device, and the bolt tightening tool.

[0019] The automatic navigation and positioning system 1 integrates a high-precision GPS / Beidou positioning module, a laser radar (LiDAR), and an inertial navigation system (INS) to ensure accurate navigation and positioning in complex environments. Using a pre-set construction map and path planning algorithm, the equipment automatically drives to the designated photovoltaic module installation location according to instructions. By collaborating with other construction equipment, efficient scheduling is achieved on the construction site. The visual recognition system 2, equipped with a high-resolution industrial camera and image processing unit, captures images of photovoltaic module joints in real time. Using machine learning algorithms to analyze these images, it is able to capture and analyze real-time image information of photovoltaic modules and bolted joints, such as identifying bolt hole location, angle, and size, to provide precise guidance for the robotic arm. The robotic arm and gripper device 3 utilizes a multi-joint, multi-degree-of-freedom industrial robotic arm, offering high flexibility and precision. The end-mounted gripper device can be designed based on the specific shape of the photovoltaic module and bolt, utilizing anti-slip and anti-scratch materials to ensure stable gripping without damaging the module. Based on instructions from the visual recognition system 2, the robotic arm can flexibly adjust its posture, accurately gripping the photovoltaic module and bolt for stable fixation. Driven by a servo motor, the robotic arm can precisely control the movement speed and position of the gripper. The bolt tightening tool 4 includes an electrically or pneumatically driven tightening device with a built-in torque sensor and controller. The tightening device automatically completes bolt insertion, pre-tightening, and final tightening operations, automatically adjusting the tightening force based on a preset torque value to ensure that each bolt meets a uniform tightening standard. A quick-change fixture is also included to accommodate bolts of varying specifications and models. The centralized control system 5 is built based on an industrial-grade PLC (Programmable Logic Controller) or embedded system, and is responsible for receiving data from various sensors, performing real-time processing and analysis, and issuing corresponding control instructions to achieve overall control and scheduling of the equipment; it integrates a touch screen human-computer interaction interface to facilitate operators to set parameters, monitor equipment status, and receive fault alarms; it supports remote communication functions, and operators can remotely monitor equipment operation through mobile phone APP or computer software and make necessary interventions and adjustments.

[0020] like Figure 2 As shown, the specific method of use of the utility model is as follows:

[0021] Step 1: Preparation

[0022] Before construction begins, the equipment is placed at the preset starting position, and the construction map and path planning are loaded through the centralized control system 5;

[0023] Check whether all functions of the equipment are normal, including navigation positioning, visual recognition, robotic arm movement and bolt tightening.

[0024] Step 2: Navigate to the construction location

[0025] The equipment automatically drives to the photovoltaic panel installation location according to the preset path;

[0026] The automatic obstacle avoidance system can be used to avoid obstacles along the way to ensure driving safety.

[0027] Step 3: Visual recognition and positioning

[0028] After arriving at the construction location, the visual recognition system 2 is activated to capture and analyze images of the photovoltaic module connections;

[0029] After identifying the bolt hole position, angle and other information, the coordinate data is transmitted to the centralized control system 5.

[0030] Step 4: Clamping and Fixing

[0031] The centralized control system 5 controls the robotic arm to move to the designated position and clamp the photovoltaic module or bolt through the clamping device;

[0032] Force feedback technology is used during the clamping process to ensure that the clamping force is moderate and stable.

[0033] Step 5: Bolt tightening

[0034] The centralized control system 5 controls the robotic arm to move to the designated position and clamp the photovoltaic module or bolt through the clamping device;

[0035] Force feedback technology is used during the clamping process to ensure that the clamping force is moderate and stable.

[0036] Step 6: Complete the job and move to the next location

[0037] After completing the bolt tightening of a connection, the equipment automatically releases the clamping device and moves to the next construction position.

[0038] Repeat the above steps until all the bolts at the joints are tightened.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.
