[0002] With the growth of global demand for sustainable energy and the improvement of environmental awareness, solar photovoltaic power generation has been widely used and developed rapidly due to its clean, safe, endless and renewable characteristics. Photovoltaic panels, as the core components of solar photovoltaic power generation systems, are mainly composed of solar cell units made of polycrystalline silicon, monocrystalline silicon or other new thin film materials, which are encapsulated under photovoltaic panels with high light transmittance and moderate mechanical strength, forming a device that can both transmit light and efficiently convert solar energy into electrical energy.

[0003] Photovoltaic panels have unique aesthetic value and functional advantages, such as controllable light transmission, excellent energy-saving power generation performance, and no additional fuel consumption, greenhouse gas and other pollutant emissions throughout the entire life cycle, greatly reducing the environmental impact of energy production. However, due to the relatively brittle physical properties of photovoltaic panel materials and their easy damage by external impact, especially during the manufacturing process and subsequent transportation, the requirements for their protection measures are extremely high.

[0004] The traditional method of transporting photovoltaic panels in factories usually relies on manual labor to push carts carrying photovoltaic panels for transportation. This method is not only inefficient and labor-intensive, but also difficult to ensure that each photovoltaic panel can be fully and effectively protected during actual operation. Frequent manual contact and handling can easily cause microcracks or surface damage to the panels due to collisions, scratches, etc., which in turn affects the photovoltaic conversion efficiency and service life of the photovoltaic panels, increasing production costs and potential safety hazards.

DETAILED DESCRIPTION

[0023] like Figures 1 to 4 As shown, an AGV transport vehicle for transporting photovoltaic panels, a driving wheel 5 is symmetrically provided in the middle of the lower surface of the AGV transport vehicle 1, a plurality of universal wheels 6 are symmetrically provided at the front and rear of the AGV transport vehicle 1, two universal wheels 6 on one side of the universal wheel 6 are arranged on both sides of the driving wheel 5, a plurality of transport frames 7 are provided on the AGV transport vehicle 1, the transport frame 7 includes a base 704, a sliding drawer 703 is provided on the base 704, at least two card seats 702 are provided on the drawer 703, side stabilizing frames 707 are also provided on both sides of the base 704, and protective sponges 708 are provided on the inner walls of the side stabilizing frames 707.

[0024] In the logistics system of a modern photovoltaic panel production workshop, an innovatively designed transport rack 7 is used to effectively ensure the safety and efficiency of photovoltaic panels 8 during the circulation process in the factory. The transport rack 7 is equipped with a removable drawer 703, which is used to facilitate operators to smoothly transfer the photovoltaic panels 8 that have just been produced from the production line to the card holder 702 inside the transport rack. This design can reduce the potential risk of damage to the photovoltaic panels caused by manual handling.

[0025] After the drawer plate 703 is pulled out, the photovoltaic panel 8 is accurately placed in the holder 702, and then firmly fixed between the two side stabilizer frames 707 through a pushing operation. The two side stabilizer frames are designed with appropriate spacing and clamping structures, which can provide all-round protection for the photovoltaic panel and prevent damage due to bumps or vibrations during transportation.

[0026] When multiple photovoltaic panels 8 are installed in place according to the prescribed order, the entire transport rack loaded with photovoltaic panels will be taken over by the advanced automatic guided vehicle AGV. This AGV transport vehicle adopts intelligent navigation and preset program control, and can realize fully automated and high-precision material handling according to the predetermined optimal transportation route, which significantly improves the transportation efficiency of photovoltaic panels in the factory. In addition, due to the reduction of manual intervention, the transportation process is more stable and reliable, effectively reducing the damage rate and safety hazards of products in the internal circulation stage.

[0027] In the design of a specific transport device for photovoltaic panels or other precision equipment, the base 704 is used as a basic component for support and bearing, and side stabilizers 707 are configured on both sides. The purpose of designing these side stabilizers 707 is to further enhance the stability of photovoltaic panels or other objects during movement and storage, and to prevent the equipment from being displaced or damaged due to shaking or impact.

[0028] The inner wall of the side stabilizing frame 707 is specially provided with a protective sponge 708, which is a cushioning and shock-absorbing material that can provide soft and effective contact protection after the photovoltaic panel is placed and fixed in the holder 702. The protective sponge 708 can absorb and disperse various impact forces and vibrations generated during transportation, thereby minimizing potential damage to the surface of the photovoltaic panel and its internal fine structure, ensuring that its factory quality and use efficiency are not affected by the transportation link.

[0029] In the preferred embodiment, the cross section of the base 704 is provided with a slide groove, and the groove body is provided with an opening, and the two sides of the opening are provided with limiting ribs, and the draw plate 703 is arranged inside the slide groove, and the two sides of the upper surface of the draw plate 703 abut against the inner surface of the limiting rib. After the draw plate 703 is pulled out, a cantilever structure will be formed, but the two sides of the upper surface of the draw plate 703 abut against the inner surface of the limiting rib to increase the supporting force of the cantilever, and the photovoltaic panel 8 can be better placed on the card seat 702.

[0030] In the preferred embodiment, a slide bar 710 is further provided at the bottom of the drawer plate 703, and the slide bar 710 is slidably connected to the bottom surface of the base 704. The drawer plate 703 has a better sliding effect and plays a role in guiding the sliding.

[0031] In the design of the photovoltaic panel transport device, a cross-sectional slide structure is used inside the base 704, and an opening is opened on the slide. Limiting ribs are carefully arranged on both sides of the opening to form a delicate and stable activity space for the drawer 703. The drawer 703 is cleverly installed inside the slide, and both sides of its upper surface are tightly fitted to the inner surface of the limiting rib. This design can ensure that the drawer maintains a stable and precise movement trajectory during the process of drawing out and retracting.

[0032] When the drawer 703 is fully drawn out, a cantilever-like structure is indeed formed. However, thanks to the good abutment and cooperation between the two sides of its upper surface and the limit retaining edge, the support strength and stability of the drawer are greatly enhanced. In this way, when the staff places the photovoltaic panel 8 on the holder 702 on the top of the drawer, even if the drawer is in the extended state, sufficient load-bearing capacity and balance can be ensured, so that the photovoltaic panel can be safely and securely placed and transferred, effectively preventing the risk of the photovoltaic panel falling or being damaged due to the instability of the drawer during transportation. This design not only ensures transportation safety, but also significantly improves the convenience of operation and work efficiency.

[0033] In the preferred solution, both sides of the base 704 are provided with limiting slide grooves 706, and the end of the draw plate 703 is provided with limiting sliders 705, and the limiting sliders 705 are slidably connected with the limiting slide grooves 706, and the length of the limiting slide grooves 706 is 2 / 3 of the length of the base 704, or 1 / 2. In this sub-case, the length of the limiting slide grooves 706 is preferably 2 / 3 of the length of the base 704, and the length of the draw plate 703 when it is pulled out is 2 / 3 of the length of the base 704. If it is pulled out too long, the cantilever of the draw plate 703 will increase and become unstable. Therefore, the length of the draw plate 703 when it is pulled out is moderate, the cantilever structure is short, and the supporting force is stable.

[0034] In the design of this photovoltaic panel transport device, limiting slide grooves 706 are carefully arranged on both sides of the base 704 to ensure the precise guidance and stable operation of the drawer 703 during the withdrawal and retraction process. A limiting slider 705 is installed at the end of the drawer 703, and the slider is slidably connected with the limiting slide groove 706 to limit the movement range of the drawer 703 and prevent it from being excessively withdrawn too far.

[0035] The designer prefers that the length of the limit slide 706 is 2 / 3 of the total length of the base 704. The advantage of this is that when the drawer 703 is fully drawn out, its extended portion also occupies exactly 2 / 3 of the length of the base. This design consideration is mainly to avoid the cantilever structure being too prominent due to the drawer being drawn out too long. The longer the cantilever, the worse the structural stability, and there is a greater risk of bending and deformation, which is not conducive to the stable placement and transportation of the photovoltaic panel.

[0036] Therefore, by setting the extension length of the limit slide groove 706 and the drawer plate 703 to 2 / 3 of the length of the base 704, the cantilever structure remains shorter after the drawer plate is pulled out, and the supporting force is more sufficient and stable, which not only meets the needs of safe and stable placement of the photovoltaic panels, but also ensures the mechanical stability and durability of the entire transportation equipment during operation.

[0037] In the preferred embodiment, the cross section of the card base 702 is a U-shaped structure, a rubber pad is provided on the surface of the card base 702, and a guide surface is provided at the upper opening of the card base 702. The rubber pad plays a better protective role.

[0038] In a preferred embodiment, the length of the side stabilizing frame 707 is 2 / 3 or 1 / 2 of the length of the base 704. The length of the side stabilizing frame 707 is 2 / 3 of the length of the base 704, so that the photovoltaic panel 8 can be placed without interference from the side stabilizing frame 707.

[0039] In the preferred embodiment, a guiding inclined surface is provided at one end of the protective sponge 708, and a limiting retaining edge 709 is provided at the other end.

[0040] In this application scenario, the protective sponge 708 is a key component specially designed to provide buffer protection during the transportation of the photovoltaic panel 8. The design with a guiding slope at one end makes it smoother and more convenient to insert the photovoltaic panel into the protective sponge, reducing the resistance and potential scratch risk that may be encountered when inserting the panel. The slope guidance helps the panel to be accurately embedded in the appropriate position of the protective sponge according to the predetermined path.

[0041] On the other hand, a limit rib 709 is set at the other end of the protective sponge. This limit structure plays a vital role. It can accurately locate the depth and lateral position of the photovoltaic panel insertion, prevent the panel from being over-inserted or moving forward, backward or left and right during transportation, and effectively protect the edge of the photovoltaic panel from being damaged by collision or shaking. This ingenious structural design not only ensures the stability of the photovoltaic panel during storage and transportation, but also fully considers the convenience and safety of panel loading and unloading operations, reflecting the rigor and practicality of industrial design in controlling details.

[0042] In the preferred embodiment, a handle 701 is further provided at the end of the drawer plate 703 to facilitate the drawer plate 703 to be drawn out.

[0043] In the preferred solution, multiple radars 3 are arranged around the AGV transport vehicle 1, an alarm device 2 is arranged in front of the AGV transport vehicle 1, and a control panel 10 is arranged at the rear. In the advanced and efficient photovoltaic panel transportation system, the AGV transport vehicle 1 plays a vital role. Multiple radar 3 devices are arranged around the transport vehicle, and these radar systems are mainly used to detect the surrounding environmental information in real time, such as the distance, shape and dynamic changes of obstacles, to achieve autonomous navigation, obstacle avoidance and other functions, and ensure that the AGV transport vehicle can drive and transport photovoltaic panels safely and accurately in the factory area.

[0044] In addition, an alarm device 2 is installed in front of the AGV transport vehicle 1. When an emergency situation or a possible danger is predicted, the device will immediately send out a warning signal to remind on-site staff or link other intelligent systems to take corresponding measures to ensure production and transportation safety.

[0045] At the rear of the AGV transport vehicle 1, a control panel 10 is installed. This control panel is an important operating interface of the AGV transport vehicle. Through it, the operating status of the vehicle can be monitored, and the transportation route can be adjusted and planned. At the same time, various parameters of the vehicle can also be set and calibrated to meet the transportation needs in different scenarios, further improving the efficiency and reliability of photovoltaic panels in the process of automated transportation within the factory.

[0046] In the preferred embodiment, anti-collision strips 4 are provided at both the front and rear ends of the AGV transport vehicle 1. The design of the AGV transport vehicle 1 takes safety and protection performance into consideration, and anti-collision strips 4 are provided at both the front and rear ends. The main function of the anti-collision strips is to enhance the vehicle's ability to buffer accidental collisions during automatic driving, and to prevent direct collisions from causing damage to the goods or damage to surrounding facilities. When the AGV transport vehicle moves in the operating area, especially when approaching obstacles, walls or other objects, even if the precise detection and control system of the radar 3 system fails or responds insufficiently, the anti-collision strips can serve as the last line of defense to absorb and disperse the impact force, thereby minimizing the risk of potential accidents. This design not only protects the structural integrity of the AGV itself, but also ensures the safety of the photovoltaic panels and other surrounding equipment it carries.

[0047] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
