Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic frame technology, and in particular relates to a photovoltaic frame that is conducive to frame splicing. Background Technology

[0002] In the production and manufacturing of photovoltaic modules, frame assembly is an indispensable and crucial step. Its core purpose is to connect the cut profile segments into a sturdy rectangular frame to protect the photovoltaic glass and cells and provide reliable installation support.

[0003] Currently, the industry almost entirely uses traditional connection methods with aluminum profiles, angle brackets, and fastening bolts (or rivets). Although this technology is widely used, its inherent drawbacks severely restrict further optimization of production efficiency and costs. The process is complex and has a significant efficiency bottleneck: the entire process involves the handling, alignment, drilling and fastening of multiple parts, with many steps. Whether in automated equipment or manual operation, this is a relatively time-consuming process, which becomes a bottleneck to improving the overall production cycle time.

[0004] Automation is complex and the equipment is expensive: To achieve automated frame assembly, it is necessary to design a complex robot end effector and integrate a screwdriver system that can precisely control the torque. Such equipment is not only expensive and complex to maintain, but also requires extremely high positioning accuracy, which reduces the reliability of the system.

[0005] High overall cost: In addition to the cost of profiles, additional metal fasteners such as corner brackets and bolts need to be purchased, which increases material costs. At the same time, the complicated process also leads to higher labor and equipment amortization costs. Summary of the Invention

[0006] The purpose of this invention is to provide a photovoltaic frame that facilitates frame assembly. Through a three-step rapid frame assembly, all additional fasteners such as corner brackets and bolts are completely eliminated, reducing costs while eliminating the need for fastener installation equipment and procedures. At the same time, it eliminates the need for corner bracket alignment and embedding installation, greatly reducing the difficulty of frame assembly and increasing production speed.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a photovoltaic frame that facilitates frame assembly, comprising two long side profiles, two short side profiles, and four corner support members; The long-side profile includes a main body with a hollow rectangular beam structure, a back plate integrally provided on the outer side of the top edge of the main body, and a set of strip-shaped punch holes on the outer sides of both ends of the main body; The short side profile is an L-shaped plate structure composed of a vertical plate and a horizontal plate. Both ends of the horizontal plate are provided with cuts. The portions of both ends of the vertical plate that extend beyond the cuts are provided with bending portions. The bending portions are distributed perpendicularly to the vertical plate. A set of stamped inner protrusions that cooperate with punching holes are provided on the bending portions. Several through holes are linearly provided in the areas near the bending portions at both ends of the vertical plate. The corner support includes a top plate and a bottom plate. The top plate and the bottom plate are integrally provided with a connecting edge at the same end. A stiffening plate is provided between the top plate, the bottom plate and the connecting edge. The bottom surface of the bottom plate is provided with a number of protrusions that cooperate with the through opening. The long side profile is disposed at the same end between the two short side profiles. The end face of the long side profile is in contact with the inner side of the vertical plate. The bottom surface of the end of the main body is movably disposed on the upper surface of the vertical plate. The back of the main body is in contact with the inner side of the bending part. The gap of the stamping inner protrusion is disposed in the punch hole. The corner support is located at the connection between the long side profile and the short side profile. The bottom plate is movably located on the upper surface of the horizontal plate of the short side profile. The gaps between the protrusions are located in the through openings. The top plate is flush with the upper surface of the main body. The connecting edge is in contact with the inner side of the main body.

[0008] Furthermore, it also includes a photovoltaic module, the bottom surface of which is attached to the top surface and top plate of the main body, the peripheral side of which is attached to the inner side of the back plate and the inner side of the vertical plate, and the connecting surface of the photovoltaic module with the long side profile and the short side profile is provided with an adhesive layer.

[0009] Furthermore, the through-hole is a strip-shaped structure and is distributed perpendicular to the length direction of the short side profile, and the protrusion is a strip-shaped block that fits with the through-hole with a gap.

[0010] Furthermore, the punch is located at the main body of the long side profile end, and the two punches at the long side profile end are arranged side by side, one above the other.

[0011] Furthermore, the top edge of the vertical plate is flush with the top edge of the back plate, and the top surface of the photovoltaic module is flush with the top edge of the back plate.

[0012] This utility model has the following beneficial effects: This invention involves three steps: First, the long side profile is placed directly inside the bent section of the short side profile. The long side profile is then moved horizontally so that the stamped inner protrusion on the bent section naturally falls into the punched hole at the end of the long side profile. Second, the corner connector is vertically embedded from top to bottom, with its protrusion engaging with the through-hole on the short side profile, automatically completing the final positioning of the long side profile. Third, the photovoltaic module is installed, pressing the corner connector down to complete the final locking. This completely eliminates all additional fasteners such as corner brackets and bolts, reducing costs while eliminating the need for fastener installation equipment and procedures. Furthermore, it eliminates the need for corner bracket alignment and embedding, greatly reducing the difficulty of frame assembly, increasing production speed, and simplifying the assembly action to pure linear motion. The requirements for automated equipment are minimized; the robotic arm does not need complex rotation and tightening mechanisms, only basic gripping and linear movement functions are required to achieve high-speed, high-reliability automated frame assembly.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
