Description

Technical Field

[0001] This application relates to the field of photovoltaic panel frame forming technology, and in particular to a steel frame for a solar photovoltaic panel and a continuous processing equipment. Background Technology

[0002] As a core component of renewable energy utilization, solar photovoltaic (PV) modules need to operate stably in complex outdoor environments for extended periods. The frame, a key structural component of PV modules, plays a crucial role in securing the panels, providing mechanical support, resisting external environmental corrosion, and ensuring assembly precision. With the advancement of PV technology towards larger scale and higher efficiency, the size of PV modules continues to increase, placing higher demands on the structural strength, assembly sealing, and dustproof performance of the frame. Simultaneously, the PV industry's demands for production efficiency and processing precision are constantly rising. Continuous processing equipment for frames must balance forming integrity, dimensional consistency, and multi-specification adaptability to meet the practical application scenarios of large-scale production.

[0003] Currently, solar photovoltaic (PV) panel frames are mainly divided into two categories: aluminum alloy frames and steel frames. Steel frames, due to their advantages such as high mechanical strength, controllable cost, and low carbon emissions, are increasingly being used in large-scale PV modules. Steel frames are typically manufactured using metal sheets through a bending and forming process. Their structure generally includes load-bearing structures to support the PV panels and reinforcing structures to enhance overall strength. Some frames are designed with groove structures for mounting the PV panels to achieve precise positioning and assembly. Regarding processing equipment, existing steel frame processing equipment mostly consists of a forming mechanism, a conveying mechanism, and a cutting mechanism. The metal sheets are bent and formed using roller sets, and then cut to a preset length by the cutting mechanism. Some equipment is equipped with simple guide structures to assist in the conveying of the sheets.

[0004] Regarding the aforementioned technologies, the inventors believe that the dust protection design in the frame structure is insufficient, and external dust can easily seep in through the gap between the photovoltaic panel and the frame, affecting the assembly sealing and power generation efficiency of the module. Summary of the Invention

[0005] The purpose of this application is to provide a steel frame for solar photovoltaic panels and a continuous processing equipment to improve the problem of insufficient dust protection design in the frame structure design, which allows external dust to easily seep in through the gap between the photovoltaic panel and the frame, affecting the assembly sealing and power generation efficiency of the module.

[0006] This application provides a steel frame for a solar photovoltaic panel and a continuous processing equipment, which adopts the following technical solution: A steel frame for a solar photovoltaic panel includes an integrally bent frame body. The sidewall of the frame body is bent along its length to form a load-bearing beam. A reinforcing beam is provided below the load-bearing beam on the frame body. An installation groove for mounting the photovoltaic panel is provided above the load-bearing beam on the frame body. A dustproof protrusion is provided above the load-bearing beam on the frame body, and the dustproof protrusion extends along the upper surface of the photovoltaic panel.

[0007] By adopting the above technical solutions, the integrated bent frame body eliminates the stress concentration problem of traditional spliced ​​frame joints. The load-bearing beam provides a stable support foundation for the photovoltaic panel, and the reinforced beam specifically enhances the overall structural strength of the frame body, effectively resisting the deformation risks caused by outdoor wind and snow loads. The mounting groove enables precise positioning and assembly of the photovoltaic panel, and the dustproof protrusion extends along the upper surface of the photovoltaic panel, which can prevent external dust from entering the gap between the photovoltaic panel and the mounting groove, avoiding dust accumulation that affects the assembly sealing and the photovoltaic panel's power generation efficiency.

[0008] Optionally, one side of the dustproof protrusion is bent to form a dustproof A-side that contacts the photovoltaic panel, and the height of the dustproof A-side is a certain distance lower than the height of the dustproof protrusion.

[0009] By adopting the above technical solution, the dustproof A side is in direct contact with the photovoltaic panel and its height is lower than the dustproof protrusion. On the one hand, the close contact further blocks the dust infiltration channel and improves the dustproof sealing effect. On the other hand, the height difference allows for slight deformation space due to thermal expansion and contraction of the photovoltaic panel, avoiding rigid compression that could cause damage to the frame or the edge of the photovoltaic panel. While ensuring dustproof performance, it also improves the assembly compatibility and durability of the frame and the photovoltaic panel.

[0010] Optionally, the load-bearing beam has a B-side with an enlarged beam surface on the side away from the plate frame body, and the B-side is arranged in an arc facing the load-bearing beam.

[0011] By adopting the above technical solutions, the B-side of the load-bearing beam is designed to be larger, increasing the contact area with the photovoltaic panel, effectively dispersing the load transmitted by the photovoltaic panel, and avoiding local stress concentration that could cause microcracks in the photovoltaic panel; the arc-shaped structural design not only reduces residual stress during processing and lowers the probability of deformation after the frame is formed, but also avoids damage caused by sharp edges and corners during assembly and use, further optimizing load-bearing stability and structural service life.

[0012] Optionally, the reinforcing beam is bent into a C-surface on one side, and the C-surface is bent in an arc shape towards the height direction of the frame body. The distance between the C-surface and the frame body is greater than the distance between the A-surface and the B-surface and the frame body.

[0013] By adopting the above technical solution, the C-side of the reinforcing beam adopts an arc-shaped bending structure, which significantly improves the torsional and deformation resistance of the reinforcing beam itself compared with the planar structure. The distance between the C-side and the frame body is greater than that between the A-side and the B-side, making the reinforcing beam an independent and strengthened mechanical support unit. Together with the load-bearing beam and the dustproof protrusion, it forms a staggered force system, making the force on each part of the frame body more balanced.

[0014] A continuous processing device for a steel frame of a solar photovoltaic panel includes a forming roller assembly for processing a steel frame of a solar photovoltaic panel and an installation frame connected to the forming roller assembly. The forming roller assembly continuously bends and forms the frame body multiple times. At one end of the installation frame located in the discharge area of ​​the forming roller assembly, a flattening forming component corresponding to the frame body is provided. The flattening forming component receives the frame body formed by the forming roller assembly. At the end of the installation frame, a cutting component is provided to receive the flattened frame body.

[0015] By adopting the above technical solutions, the forming roller assembly ensures the continuity and consistency of the forming of each structure of the frame through continuous multiple bending forming, avoiding structural defects caused by single forming; the flattening forming assembly integrated with the mounting frame can perform targeted flattening treatment on the formed frame, solving the flatness and straightness deviation problems that are prone to occur in continuous processing; the cutting assembly realizes the precise cutting of the formed frame. The whole equipment integrates the entire process of forming, flattening and straightening, and cutting, reducing the time spent on process connection, improving production efficiency, and ensuring the stability of frame forming quality and dimensional accuracy.

[0016] Optionally, the forming roll assembly includes multiple sets of forming rolls arranged sequentially along the length of the mounting frame. Each set of forming rolls corresponds to the progressive forming of the load-bearing beam, reinforcing beam, dustproof protrusion, dustproof A side, B side, and C side of the frame body. The processing accuracy of adjacent forming roll sets increases sequentially. The mounting frame is provided with a drive component for driving the forming roll sets to rotate.

[0017] By adopting the above technical solution, multiple forming roll groups are arranged sequentially along the length of the installation frame, and progressive forming is carried out on each structure of the frame to prevent excessive stretching or extrusion of the steel plate by a single forming, thereby reducing structural deformation and residual stress. The design of progressively increasing processing precision enables the structure of each part of the frame to be formed gradually and accurately, ensuring the dimensional accuracy and positional accuracy of key structures such as load-bearing beams, reinforcing beams, and dustproof protrusions.

[0018] Optionally, the flattening and forming assembly includes a flattening seat arranged along the length of the mounting frame. The flattening seat has a forming groove along its length that corresponds to the cross-sectional shape of the frame body. A rotating wheel is rotatably arranged at one end of the flattening seat near the forming roller assembly, which contacts the side wall of the frame body. A second driving component is arranged on the outside of the flattening seat to drive the rotating wheel to rotate and stably feed the roll-formed frame body into the forming groove.

[0019] By adopting the above technical solution, the shaping groove of the flat seat is precisely matched with the cross-sectional shape of the photovoltaic panel frame, which can perform full-circumferential fitting shaping of the frame and effectively correct slight bumps or warping that occur during the forming process. The rotating wheel, together with the second drive component, provides stable conveying power for the frame, ensuring that the frame is smoothly fed into the shaping groove, preventing shaping deviations caused by offset during feeding, and significantly improving the flatness and straightness of the frame after processing.

[0020] Optionally, the inner sidewall of the shaping groove is arc-shaped towards the end of the flattening seat, and the circumferential sidewall of the rotating wheel is provided with several grooves. The flattening seat is provided with auxiliary wheels on both sides of the photovoltaic panel frame that rotatably contact the frame body.

[0021] By adopting the above technical solutions, the arc design of the inner sidewall of the shaping groove enables a smooth transition when the frame enters the shaping groove, avoiding scratches or structural damage to the frame surface caused by sharp edges and corners, and protecting the appearance quality and plating integrity of the frame; the groove of the rotating wheel is adapted to the shape of the frame body and enhances the friction with the frame, preventing deformation of the frame body during the transfer process, ensuring stable conveying power, and preventing insufficient shaping due to slippage; the close contact between the auxiliary wheel and the sidewall of the frame further restricts the displacement of the frame, ensuring the stability of the flattening process in all aspects, and improving the smoothness of the frame surface and the shaping accuracy.

[0022] Optionally, the cutting assembly includes a cutting base supporting the frame body and a cutting head moving toward the cutting base. The cutting base is provided with a first driving cylinder for driving the cutting head to move downward to cut the frame body. The cutting base is slidably provided with clamping blocks on both sides of the frame body that abut against the frame body. The cutting base is provided with a second driving cylinder for driving the clamping blocks to move.

[0023] By adopting the above technical solution, the clamping block of the cutting component clamps the frame before cutting, and the mechanical clamping and fixing prevents the frame from shifting during the cutting process, preventing the cut from being crooked or the size deviation, and ensuring the cutting accuracy; the drive cylinder provides stable and controllable cutting power, ensuring that the cutting head completes the cutting quickly and accurately, reducing burrs and deformation of the cut, and the coordinated action of clamping and cutting ensures that the cut is flat, reduces the waste rate, and reduces secondary processing costs.

[0024] Optionally, the mounting frame is provided with a linear motor module along its length direction to drive the cutting base to move along the length direction of the mounting frame. The cutting base has a positioning groove corresponding to the cross section of the frame body, and the clamping block has a clearance groove corresponding to the cutting head.

[0025] By adopting the above technical solution, the linear motor module drives the cutting base to move along the length of the mounting frame, which can accurately adjust the cutting length according to the needs of different photovoltaic modules, realize flexible processing of multi-specification frames, and improve equipment adaptability; the positioning groove matches the frame cross-section, further improving the positioning accuracy during cutting and ensuring that the cutting size error is controlled within a reasonable range; the clearance groove of the clamping block provides clearance space for the cutting head, avoiding interference between the cutting head and the clamping block, ensuring smooth cutting process, while the clamping block continuously and stably clamps the frame, taking into account cutting efficiency and accuracy, and improving the processing flexibility and practicality of the equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The integrated bent frame body eliminates the stress concentration problem of traditional spliced ​​frame joints, effectively resisting the deformation risk caused by outdoor wind load and snow load. The mounting groove enables precise positioning and assembly of photovoltaic panels. The dustproof protrusion extends along the upper surface of the photovoltaic panel, which can block external dust from entering the gap between the photovoltaic panel and the mounting groove, avoiding dust accumulation that affects the assembly sealing and photovoltaic panel power generation efficiency. 2. The shaping groove of the flat seat is precisely matched with the cross-sectional shape of the photovoltaic panel frame, which can perform full-circumferential fitting shaping of the frame and effectively correct slight bumps or warping that occur during the forming process; the rotating wheel and the drive component provide stable conveying power for the frame, ensuring that the frame is smoothly fed into the shaping groove, preventing shaping deviation caused by offset during feeding, and significantly improving the flatness and straightness of the frame after processing. 3. The clamping block of the cutting component clamps the edge before cutting, and the mechanical clamping fixes it to prevent the edge from shifting during the cutting process, thus preventing the cut from being crooked or the size deviation, and ensuring the cutting accuracy. The drive cylinder provides stable and controllable cutting power to ensure that the cutting head completes the cutting quickly and accurately, reducing burrs and deformation of the cut. The coordinated action of clamping and cutting ensures that the cut is flat, reduces the waste rate, and reduces secondary processing costs. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below. Example

[0030] A steel frame for a solar photovoltaic panel, as shown in the reference. Figure 1 The frame body 1 is formed by continuous bending, eliminating the need for additional splicing processes and thus preventing stress concentration issues caused by splicing seams. The sidewall of the frame body 1 is naturally bent along its length to form a load-bearing beam 11, which is directly attached to the bottom edge of the photovoltaic panel and bears the main weight load of the photovoltaic panel. The side of the load-bearing beam 11 away from the frame body 1 extends outward to form a B-side 111. The B-side 111 is designed as an enlarged beam structure with an overall arc transition, and the contact area with the photovoltaic panel is smooth and without sharp edges.

[0031] Reference Figure 1A reinforcing beam 12 is formed by bending simultaneously below the load-bearing beam 11. The reinforcing beam 12 is integrated with the frame body 1. One side of the reinforcing beam 12 is bent towards the height of the frame body 1 to form a C-surface 121. The C-surface 121 has a smooth arc shape. The distance between the C-surface 121 and the frame body 1 is significantly greater than the distance between the dustproof A-surface 141 and B-surface 111 and the frame body 1. This makes the reinforcing beam 12 an independent reinforced support structure, forming a coordinated force system with the load-bearing beam 11. An installation groove 13 is reserved above the supporting beam 11. The size of the installation groove 13 is adapted to the edge thickness of the photovoltaic panel for stable embedding of the photovoltaic panel. A dustproof protrusion 14 is simultaneously bent on one side of the installation groove 13. The dustproof protrusion 14 extends horizontally along the upper surface of the photovoltaic panel. The side of the protrusion close to the photovoltaic panel is bent downward to form a dustproof A-side 141. The dustproof A-side 141 is closely attached to the upper surface of the photovoltaic panel, and the height of the dustproof A-side 141 is lower than the top of the dustproof protrusion 14, forming a stepped double dustproof structure. Example

[0032] A continuous processing equipment for steel frames of solar photovoltaic panels, referring to Figure 2 and Figure 3 The system includes 21 forming roll groups 2 for processing the steel frame of a solar photovoltaic panel, and an installation frame 3 connected to the forming roll groups 21. The forming roll groups 21, a leveling and forming component 4, and a cutting component 5 are arranged sequentially along the length of the installation frame 3. The forming roll groups 21 consist of multiple forming roll groups 21. Each roll group has forming grooves on its upper and lower roll surfaces that are adapted to the corresponding structure of the frame. Starting from the raw material input end, the first roll group initially bends the steel plate to outline the frame body 1. The basic outline is formed; the subsequent roll groups are processed step by step in the forming sequence of bearing beam 11, reinforcing beam 12, dustproof protrusion 14, dustproof A side 141, B side 111 and C side 121. The forming accuracy of each roll group is gradually improved compared with the previous group to ensure that each structure is formed completely and the dimensions are accurate; the drive component 22 configured on the mounting frame 3 is a servo motor, which is connected to each forming roll group 21 through a chain or gear transmission mechanism to realize synchronous speed control of each roll group and avoid stretching or wrinkling during the steel plate conveying process.

[0033] Reference Figure 3 , Figure 4 and Figure 5The flattening base 41 of the flattening forming component 4 is fixed to the discharge area of ​​the mounting frame 3. The length of the flattening base 41 is adapted to the processing width of the frame. A forming groove 42 is opened through its interior. The inner sidewall contour of the forming groove 42 perfectly matches the cross-sectional shape of the frame. The inner sidewall of the forming groove 42 near the forming roller group 21 adopts an arc transition design to facilitate the smooth entry of the frame. A rotating wheel 43 is rotatably connected to the end of the flattening base 41 near the forming roller group 21 through a bearing. Several grooves 431 are evenly distributed on the circumferential sidewall of the rotating wheel 43. The inner sidewall of 31 is adapted to the shape of the frame body 1 to enhance the friction with the frame surface and to perform preliminary flattening and straightening processing when the frame body 1 is transferred; the second driving component 44 is a stepper motor, which drives the rotating wheel 43 to rotate through belt or wheel drive to provide stable power for the frame to be fed into the shaping groove 42; the flat seat 41 is located on both sides of the shaping groove 42 and is rotatably connected to the auxiliary wheel 45 through the bracket. The circumferential surface of the auxiliary wheel 45 is polished and fits tightly with the sidewall of the frame. It can rotate synchronously with the movement of the frame and play a guiding and limiting role.

[0034] Reference Figure 3 and Figure 4 The cutting base 51 of the cutting component 5 is slidably connected to the linear motor module 31 of the mounting frame 3 via a slider. The linear motor module 31 can drive the cutting base 51 to reciprocate along the length of the mounting frame 3 to meet the cutting requirements of borders of different lengths. A positioning groove 56 is provided on the top of the cutting base 51. The cross-sectional shape of the positioning groove 56 is perfectly adapted to the border and is used to place the border to be cut and to initially position it. Clamping blocks 54 are symmetrically arranged on both sides of the cutting base 51. The clamping blocks 54 slide in cooperation with the slide rail of the cutting base 51. The second drive cylinder 55 is fixed to the side of the cutting base 51. The piston rod of the cutting head 52 is rigidly connected to the clamping block 54, which can drive the clamping block 54 to move towards the positioning groove 56 and clamp the frame. The cutting head 52 is made of hard alloy material. The driving cylinder 53 is fixed on the top bracket of the cutting base 51. Its piston rod is fixedly connected to the cutting head 52, which can drive the cutting head 52 to move quickly in the vertical direction. The clamping block 54 has a clearance groove 541 on the side near the positioning groove 56. The position and size of the clearance groove 541 correspond precisely to the cutting head 52, ensuring that the cutting head 52 can pass smoothly through the clamping block 54 when it moves down, avoiding interference and completing precise cutting.

[0035] The implementation principle of this application embodiment is as follows: The frame body 1 is integrally bent and formed, using a continuous forming process to replace the traditional splicing process. This eliminates stress concentration points at the splicing joints and avoids deformation and cracking caused by stress release in complex outdoor environments. The load-bearing beam 11, as the main load-bearing structure, directly bears the weight of the photovoltaic panel. By enlarging the B-side 111 design of the beam surface, the contact area with the photovoltaic panel is increased, dispersing the concentrated load into a uniform load and reducing the risk of microcracks at the edges of the photovoltaic panel. The arc-shaped B-side 111 structure not only reduces residual stress during processing but also avoids impact damage during assembly and use. The reinforcing beam 12, through its arc-shaped C-side 121 structural design, utilizes the mechanical advantages of the arc structure to enhance its torsional and deformation resistance. At the same time, the larger installation spacing allows the reinforcing beam 12 to form an independent support unit, echoing the load-bearing beam 11 from top to bottom, achieving overall stress balance of the frame and significantly improving its ability to resist extreme loads such as wind and snow loads. The stepped design of the dustproof protrusion 14 and the dustproof A-side 141 forms a double dustproof barrier. The dustproof protrusion 14 blocks most of the external dust, and the tight fit between the dustproof A-side 141 and the photovoltaic panel further seals the dust infiltration channel, ensuring the assembly and sealing of the photovoltaic panel and the frame, and preventing dust accumulation from affecting the heat dissipation and power generation efficiency of the photovoltaic panel. The forming roll assembly 21 pieces 2 achieves the gradual forming of each structure of the frame through multiple sets of rolls with increasing precision, avoiding structural deformation caused by excessive extrusion or stretching of the steel plate during single forming. The forming groove of each roll assembly is precisely matched with the corresponding structure to ensure the complete forming of each part. The synchronous power provided by the drive component 1 22 ensures that the steel plate conveying speed matches the roll speed, preventing uneven stretching or wrinkles, and further improving the forming consistency. The core function of the flat forming component 4 is to correct forming deviations. The rotating wheel 43 enhances the friction with the frame through the groove 431. Driven by the drive component 2 44, the frame is stably fed into the forming groove 42. The auxiliary wheel 45 restricts the displacement of the frame from both sides, ensuring that the frame moves along the central axis of the forming groove 42. The forming groove 42 performs full-circumferential fitting forming of the frame through a contour that is perfectly matched with the frame cross-section, correcting slight bumps and warping that may occur during the forming process, and improving the flatness and straightness of the frame. The linear motor module 31 drives the cutting base 51 to move to the designated position according to the preset frame length. The positioning groove 56 performs initial positioning of the frame. The second drive cylinder 55 drives the clamping block 54 to clamp the frame. The mechanical clamping fixation prevents the frame from shifting during the cutting process and ensures the cutting dimension accuracy. The first drive cylinder 53 drives the cutting head 52 to move down quickly. The sharpness of the carbide cutting head is used to achieve precise cutting. The clearance groove 541 of the clamping block 54 provides clearance space for the cutting head 52, avoiding interference and ensuring thorough cutting. After cutting, all components are reset and waiting for the next processing cycle. The entire equipment realizes continuous and high-precision processing from steel plate raw material to finished frame through the orderly linkage of various components. It not only improves production efficiency, but also ensures the structural performance and processing quality of the frame through the optimization of structural design, meeting the actual application requirements of photovoltaic modules.
