Description

Technical Field

[0001] This invention relates to the field of photovoltaic frame technology, and more specifically to an automated assembly platform for solar photovoltaic frames. Background Technology

[0002] With the urgent global demand for clean energy and the strong support of various countries for the renewable energy industry, solar photovoltaic power generation, as an important source of clean energy, has seen its market size expand rapidly. As a key component of photovoltaic modules, the demand for photovoltaic frames has also increased accordingly. In order to meet the huge market demand, improving the assembly efficiency of photovoltaic frames has become an inevitable choice.

[0003] The existing photovoltaic frame consists of four profiles (usually aluminum alloy) connected by corner brackets to form a rectangular frame. It requires the coordinated assembly of multiple components such as four sets of profiles, four corner brackets, and connecting bolts. Manual operation requires frequent switching of tools and workstations, and the assembly of a single frame is time-consuming. Specifically, the assembly process of photovoltaic frames includes cutting frame profiles, preparing corner brackets, positioning and aligning the frames, and inserting corner brackets. Among these steps, positioning and aligning the frames is particularly crucial. It requires workers to manually or using simple tooling to precisely place the cut frame profiles on the workbench to ensure that the mating ends of each profile are tightly aligned, laying a solid foundation for subsequent connection work. However, due to the complexity of the frame components, this step is extremely cumbersome, time-consuming, labor-intensive, and difficult to guarantee accuracy, making it difficult to effectively ensure product quality. Based on this, the present invention aims to provide an automated assembly platform for solar photovoltaic frames that can improve the automation level and efficiency of photovoltaic frame assembly. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automated assembly platform for solar photovoltaic frames, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions: An automated assembly platform for solar photovoltaic frames includes four splicing frames, four corner brackets, and multiple screws. Each splicing frame has a connecting groove at both ends, and the connecting groove has a through hole and a threaded groove. The corner brackets are slidably connected to the connecting grooves. Each corner bracket has a first opening and a second opening at both ends. The first opening is away from the corner corner, and the second opening is close to the corner corner. The platform also includes an assembly platform with four mounting plates corresponding to the four splicing frames. The two left and right mounting plates are fixedly mounted on the assembly platform, and the two front and rear mounting plates are slidably mounted on the assembly platform. The two mounting plates are driven to move towards each other by a drive component. The mounting plate is provided with clamping components for clamping and fixing the splicing frame; An automated robotic arm is installed at each of the four corners of the assembly platform; The mounting plate is equipped with a pre-locking component. When the drive component drives the front and rear mounting plates to move away from each other, the four automatic robotic arms insert the four corner brackets into the connecting slots on the front and rear splicing frames respectively. When the first opening and the through hole are aligned, the pre-locking component locks the four corner brackets to the front and rear splicing frames. Subsequently, the drive component drives the front and rear mounting plates to move closer to each other. At this time, the four corner brackets are inserted into the connecting slots on the left and right splicing frames. When the first opening and the through hole are aligned, the pre-locking component locks the four corner brackets to the four splicing frames.

[0006] As a further embodiment of the present invention: the clamping assembly includes a sliding plate and two connectors, the two connectors are respectively disposed at both ends of the mounting plate and are symmetrically arranged, the sliding plate is slidably mounted on the mounting plate, and the sliding plate is driven to move by a drive source built into the mounting plate, the splicing frame is located between the two connectors and the sliding plate, when the drive source drives the sliding plate to move toward the connectors, the sliding plate will abut the splicing frame against the connectors.

[0007] As a further aspect of the present invention: the pre-locking assembly includes a plug rod, a first spring, and a first extension rod. A cavity is provided inside the connector, and the plug rod is slidably installed in the cavity. The plug rod is connected to the cavity through the first spring, and the pre-tightening force of the first spring causes the plug rod to pass through the through hole and be inserted into the connecting groove. The first extension rod is slidably installed on the connector, one end of the first extension rod is fixedly connected to the plug rod, and the other end of the first extension rod is located outside the connector. When the first opening is aligned with the through hole, the plug rod passes through the first opening and is inserted into the threaded groove.

[0008] As a further aspect of the present invention: the insertion rod has a beveled edge, and a limiting component is provided in the cavity. The limiting component is connected to the insertion rod. Before the corner code is inserted into the connecting groove, the limiting component restricts the position of the insertion rod, so that the beveled edge is located in the connecting groove. When the corner code is inserted into the connecting groove, the edge of the insertion end of the corner code abuts against the beveled edge, and as the corner code is inserted, the corner code and the beveled edge slide together, squeezing the insertion rod into the cavity.

[0009] As a further embodiment of the present invention: the limiting component includes a receiving cavity, a first L-shaped block, a second L-shaped block, and a telescopic component. The first L-shaped block is fixedly installed on the insertion rod. The receiving cavity is opened in the cavity. The second L-shaped block is slidably installed in the receiving cavity and is driven to move by the telescopic component. When the telescopic component drives the second L-shaped block to move into the cavity, the first spring pushes the insertion rod to move towards the through hole, so that the first L-shaped block and the second L-shaped block are engaged. At this time, the inclined side is located in the connecting groove. When the insertion rod is squeezed into the cavity, the first L-shaped block moves away from the second L-shaped block. At this time, the telescopic component drives the second L-shaped block to move into the receiving cavity. Then, the first spring pushes the insertion rod to pass through the through hole, the first opening, and the threaded groove in sequence.

[0010] As a further aspect of the present invention: the telescopic assembly includes a second spring and a second extension rod. The second L-shaped block is connected to the receiving cavity through the second spring, and the preload of the second spring causes the second L-shaped block to move toward the receiving cavity. The second extension rod passes through the connector and is fixedly connected to the second L-shaped block, with one end of the second extension rod located outside the connector. The second extension rod is slidably connected to the connector. When the insertion rod is squeezed and moves toward the cavity, the first L-shaped block moves away from the second L-shaped block. At this time, the preload of the second spring causes the second L-shaped block to move into the receiving cavity.

[0011] As a further aspect of the present invention: each of the mounting plates has two slots, and each connector has a plug fixedly installed thereon, the plug being slidably inserted into the slot.

[0012] As a further aspect of the present invention: when the second opening is aligned with the through hole, the screw passes through the through hole and the second opening, and the screw is threadedly connected to the threaded groove.

[0013] The beneficial effects of this invention are: 1. In this invention, by first locking the four corner brackets to the front and rear splicing frames, and then establishing a connection between the four corner brackets and the left and right splicing frames by moving the front and rear splicing frames, and then restricting the splicing frames with the clamping components, the rectangular structure formed by the four splicing frames can be easily removed. The corner brackets are not completely inserted into the splicing frames, which leaves a large space in the middle of the rectangle formed by the four splicing frames. When proceeding to the process of installing the photovoltaic panel to the frame, the photovoltaic panel can be placed directly in the space enclosed by the four splicing frames. At this time, there is still a certain amount of redundant space between the photovoltaic panel and the component splicing frame, which reduces the difficulty and complexity of the four splicing frames and the subsequent installation of the photovoltaic panel. 2. In this invention, when the corner bracket is inserted into the connecting slot, the edge of the corner bracket insertion end abuts against the bevel. As the corner bracket is inserted, the corner bracket and the bevel slide together, squeezing the insertion rod into the cavity. Subsequently, the insertion rod abuts against the surface of the corner bracket. As the corner bracket continues to be inserted, when the first opening and the through hole are aligned, the first spring pushes the insertion rod through the through hole and the second opening and inserts it into the threaded groove, thereby completing the locking of the corner bracket. This achieves the self-locking function, eliminates the step of moving the first extension rod, and improves the assembly efficiency. 3. In this invention, the connector can be inserted into the slot by inserting the plug. After the initial assembly of the four splicing frames and four corner brackets is completed, the splicing frames are moved together with the connector. At this time, the plug separates from the slot, which is conducive to the movement and transportation of the assembled splicing frames. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 As shown, the present invention is an automated assembly platform for solar photovoltaic frames, including four splicing frames 5, four corner brackets 6, and multiple screws. Each splicing frame 5 has a connecting groove 501 at both ends. The connecting groove 501 has a through hole 502 and a threaded groove 503. The corner brackets 6 are slidably connected to the connecting grooves 501. Each corner bracket 6 has a first opening 601 and a second opening 602 at both ends. The first opening 601 is away from the corner of the corner bracket 6, and the second opening 602 is close to the corner of the corner bracket 6. The platform also includes an assembly platform 1. The assembly platform 1 is provided with four mounting plates 2 corresponding to the four splicing frames 5. The two left and right mounting plates 2 are fixedly installed on the assembly platform 1, and the two front and rear mounting plates 2 are slidably installed on the assembly platform 1. The two mounting plates 2 are driven to move towards each other by a drive component. The mounting plate 2 is provided with a clamping component for clamping and fixing the splicing frame 5; An automatic robotic arm 101 is installed at each of the four corners of the assembly platform 1; The mounting plate 2 is equipped with a pre-locking component. When the drive component drives the two mounting plates 2 to move away from each other, the four automatic robotic arms 101 insert the four corner brackets 6 into the connecting slots 501 on the two splicing frames 5 respectively. When the first opening 601 is aligned with the through hole 502, the pre-locking component locks the four corner brackets 6 to the two splicing frames 5. Then the drive component drives the two mounting plates 2 to move closer to each other. At this time, the four corner brackets 6 are inserted into the connecting slots 501 on the two splicing frames 5. When the first opening 601 is aligned with the through hole 502, the pre-locking component locks the four corner brackets 6 to the four splicing frames 5.

[0019] In one embodiment, the drive assembly may be a motor-driven bidirectional lead screw assembly, an electric cylinder, an electric telescopic rod, or other components. It may also be other mechanisms capable of enabling the two mounting plates 2 to move in opposite directions. This embodiment does not impose specific limitations on these components. It should be noted that the automatic robotic arm 101 described in this invention is prior art. This invention does not improve upon it. Therefore, it is not necessary to disclose its specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0020] The working principle of this invention: Existing solar photovoltaic frame assembly involves two steps: frame assembly and installing the photovoltaic panels within the frame. To improve assembly efficiency, these two processes are separated, such as... Figure 1 Taking the example shown, firstly, the driving component drives the two mounting plates 2 to move away from each other. Then, four automated robotic arms 101 place the four splicing frames 5 onto the four mounting plates 2 respectively, and clamp the splicing frames 5 in place using a clamping component. Next, the four automated robotic arms 101 insert the four corner brackets 6 into the connecting slots 501 on the two splicing frames 5 respectively. When the first opening 601 aligns with the through hole 502, the pre-locking component locks the four corner brackets 6 to the two splicing frames 5. At this time, the connection between the splicing frames 5 and the corner brackets 6 is as shown. Figure 7 As shown, the drive assembly then drives the two mounting plates 2 to move closer together. At this time, the four corner brackets 6 are inserted into the connecting slots 501 on the left and right splicing frames 5. When the first opening 601 aligns with the through hole 502, the pre-locking assembly locks the four corner brackets 6 to the four splicing frames 5, ultimately forming the shape shown. Figure 8 The state shown indicates that the assembly of the photovoltaic frame is complete. At this point, the clamping components can be released from the restriction on the splicing frame 5, allowing the four splicing frame 5, which form a rectangle, to be removed. Due to the connection between the corner brackets 6 and the pre-locking components, the four splicing frame 5 are structurally stable, facilitating transportation and transfer. It is worth noting that the corner brackets 6 are not fully inserted into the connecting slots 501, leaving a large space in the middle of the rectangle formed by the four splicing frame 5. When the four splicing frame 5 are used to assemble the photovoltaic panel, the photovoltaic panel can be placed directly between the four splicing frame 5. At this point, there is still a large amount of redundant space between the photovoltaic panel and the splicing frame 5. The pre-locking components can then be released, and the four splicing frame 5 can be pushed towards the photovoltaic panel in the middle to complete the entire assembly task.

[0021] like Figures 1-2 As shown, in a preferred embodiment of the present invention, the clamping assembly includes a sliding plate 4 and two connecting members 3. The two connecting members 3 are respectively disposed at both ends of the mounting plate 2 and are symmetrically arranged. The sliding plate 4 is slidably mounted on the mounting plate 2 and is driven to move by a drive source built into the mounting plate 2. The splicing frame 5 is located between the two connecting members 3 and the sliding plate 4. When the drive source drives the sliding plate 4 to move toward the connecting member 3, the sliding plate 4 will abut the splicing frame 5 against the connecting member 3.

[0022] In one embodiment, the drive source may be an electric cylinder, an electric telescopic rod, or other mechanisms capable of reciprocating motion. This embodiment does not impose any specific limitations on these components.

[0023] In practical application, this embodiment places the splicing frame 5 between the two connectors 3 and the sliding plate 4. When the driving source drives the sliding plate 4 to move toward the connector 3, the sliding plate 4 will press the splicing frame 5 against the connector 3, thereby completing the clamping and fixing function of the splicing frame 5. Moreover, the sliding plate 4 is movable, so it can adapt to splicing frames 5 of different sizes.

[0024] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the pre-locking assembly includes a plug rod 7, a first spring 8, and a first extension rod 9. A cavity 301 is provided in the connector 3. The plug rod 7 is slidably installed in the cavity 301. The plug rod 7 is connected to the cavity 301 through the first spring 8, and the pre-tightening force of the first spring 8 causes the plug rod 7 to pass through the through hole 502 and be inserted into the connecting groove 501. The first extension rod 9 is slidably installed on the connector 3. One end of the first extension rod 9 is fixedly connected to the plug rod 7, and the other end of the first extension rod 9 is located outside the connector 3. When the first opening 601 is aligned with the through hole 502, the plug rod 7 passes through the first opening 601 and is inserted into the threaded groove 503.

[0025] In practical application, the sliding rod 7 in the cavity 301 can pass through the through hole 502. Therefore, after the corner bracket 6 is inserted into the connecting groove 501, the first extension rod 9 is moved to compress the first spring 8 and move into the cavity 301. When the first opening 601 and the through hole 502 are aligned, the first extension rod 9 is released, and the first spring 8 pushes the rod 7 through the through hole 502 and the second opening 602 and into the threaded groove 503, thereby locking the corner bracket 6 and preventing the corner bracket 6 from being inserted further.

[0026] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the insertion rod 7 has a bevel 701, and a limiting component is provided in the cavity 301. The limiting component is connected to the insertion rod 7. Before the corner bracket 6 is inserted into the connecting groove 501, the limiting component restricts the position of the insertion rod 7, so that the bevel 701 is located in the connecting groove 501. When the corner bracket 6 is inserted into the connecting groove 501, the edge of the insertion end of the corner bracket 6 abuts against the bevel 701. As the corner bracket 6 is inserted, the corner bracket 6 and the bevel 701 slide together, squeezing the insertion rod 7 into the cavity 301.

[0027] In practical application, this embodiment restricts the position of the insertion rod 7 by using a limiting component, so that the inclined side 701 is located within the connecting groove 501. Thus, when the corner bracket 6 is inserted into the connecting groove 501, the edge of the insertion end of the corner bracket 6 abuts against the inclined side 701. As the corner bracket 6 is inserted, the corner bracket 6 and the inclined side 701 slide together, squeezing the insertion rod 7 into the cavity 301. Subsequently, the insertion rod 7 abuts against the surface of the corner bracket 6. As the corner bracket 6 continues to be inserted, when the first opening 601 aligns with the through hole 502, the first spring 8 pushes the insertion rod 7 through the through hole 502 and the second opening 602 and into the threaded groove 503, thereby completing the locking of the corner bracket 6. This achieves a self-locking function, eliminating the need to move the first extension rod 9 and improving assembly efficiency.

[0028] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the limiting component includes a receiving cavity 302, a first L-shaped block 10, a second L-shaped block 11, and a telescopic component. The first L-shaped block 10 is fixedly installed on the insertion rod 7. The receiving cavity 302 is opened in the cavity 301. The second L-shaped block 11 is slidably installed in the receiving cavity 302, and the second L-shaped block 11 is driven to move by the telescopic component. When the telescopic component drives the second L-shaped block 11 to move into the cavity 301, the first spring 8 pushes the insertion rod 7 to move towards the through hole 502, so that the first L-shaped block 10 and the second L-shaped block 11 are engaged. At this time, the inclined side 701 is located in the connecting groove 501. When the insertion rod 7 is squeezed into the cavity 301, the first L-shaped block 10 moves away from the second L-shaped block 11. At this time, the telescopic component drives the second L-shaped block 11 to move into the receiving cavity 302. Then the first spring 8 pushes the insertion rod 7 to pass through the through hole 502, the first opening 601, and the threaded groove 503 in sequence.

[0029] In practical applications, this embodiment, such as Figure 4 As shown in the example, when the telescopic assembly drives the second L-shaped block 11 to move into the cavity 301, the first spring 8 pushes the insertion rod 7 to move towards the through hole 502, so that the first L-shaped block 10 and the second L-shaped block 11 are engaged. At this time, the inclined side 701 is located in the connecting groove 501. When the insertion rod 7 is squeezed into the cavity 301, the first L-shaped block 10 moves away from the second L-shaped block 11. At this time, the telescopic assembly drives the second L-shaped block 11 to move into the receiving cavity 302. Then, the first spring 8 pushes the insertion rod 7 to pass through the through hole 502, the first opening 601 and the threaded groove 503 in sequence. At this time, it is as follows: Figure 5 As shown, this ensures that before the corner bracket 6 is inserted into the connecting groove 501, the inclined side 701 can be located inside the connecting groove 501, thus cooperating with the corner bracket 6, and the second L-shaped block 11 can be retracted into the receiving cavity 302 to avoid blocking the moving path of the first L-shaped block 10, so that the insertion rod 7 can be inserted into the threaded groove 503 to achieve a more stable connection.

[0030] like Figures 1-5As shown, in a preferred embodiment of the present invention, the telescopic assembly includes a second spring 12 and a second extension rod 13. The second L-shaped block 11 is connected to the receiving cavity 302 through the second spring 12, and the preload of the second spring 12 causes the second L-shaped block 11 to move toward the receiving cavity 302. The second extension rod 13 passes through the connector 3 and is fixedly connected to the second L-shaped block 11. One end of the second extension rod 13 is located outside the connector 3, and the second extension rod 13 is slidably connected to the connector 3. When the insertion rod 7 is squeezed into the cavity 301, the first L-shaped block 10 moves away from the second L-shaped block 11. At this time, the preload of the second spring 12 causes the second L-shaped block 11 to move into the receiving cavity 302.

[0031] In practical applications, this embodiment, such as Figure 4 As shown in the example, when the corner bracket 6 is inserted into the connecting slot 501, the corner bracket 6 will press the insertion rod 7 after it abuts against the inclined side 701, causing the insertion rod 7 to compress the first spring 8 and move into the cavity 301. At this time, the first L-shaped block 10 will gradually separate from the second L-shaped block 11 until the insertion rod 7 is pressed against the surface of the corner bracket 6 and slides. Then, the first L-shaped block 10 and the second L-shaped block 11 are completely separated. At this time, the second spring 12 will quickly pull the second L-shaped block 11 back into the storage cavity 302 to prevent it from blocking the first L-shaped block 10. Then, after the first opening 601 and the through hole 502 are aligned, the first spring 8 pushes the insertion rod 7 to be inserted into the through hole 502, the first opening 601 and the threaded groove 503 in sequence. In this way, through the setting of the second L-shaped block 11 and the second spring 12, the second L-shaped block 11 can be automatically and quickly pulled back into the storage cavity 302, saving the step and time of shrinking the second L-shaped block 11 by operation, and making it easier to assemble the splicing frame 5.

[0032] like Figures 1-2 As shown, in a preferred embodiment of the present invention, each mounting plate 2 has two slots 201, and each connector 3 is fixedly mounted with a plug 303, which is slidably inserted into the slot 201.

[0033] In practical application, the connector 3 can be inserted into the slot 201 through the insert block 303. After the initial assembly of the four splicing frames 5 and the four corner brackets 6 is completed, the splicing frames 5 together with the connector 3 can be moved. At this time, the insert block 303 is separated from the slot 201, which is conducive to the movement and transportation of the assembled splicing frames 5.

[0034] like Figures 1-2 As shown, in a preferred embodiment of the present invention, when the second opening 602 is aligned with the through hole 502, the screw passes through the through hole 502 and the second opening 602, and the screw is threadedly connected to the threaded groove 503.

[0035] In practical application, after the four splicing frames 5 are pushed towards the photovoltaic panel in the middle to complete all the assembly tasks, the second opening 602 and the through hole 502 are aligned. At this time, the screw passes through the through hole 502 and the second opening 602, and the screw is threadedly connected to the threaded groove 503, thereby completing the final fixation.

[0036] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

When the corner bracket (6) is inserted into the connecting groove (501), the edge of the insertion end of the corner bracket (6) abuts against the bevel (701). As the corner bracket (6) is inserted, the corner bracket (6) and the bevel (701) slide together, squeezing the insertion rod (7) into the cavity (301).

5. The automated assembly platform for solar photovoltaic frames according to claim 4, characterized in that, The limiting component includes a storage cavity (302), a first L-shaped block (10), a second L-shaped block (11), and a telescopic component. The first L-shaped block (10) is fixedly installed on the insertion rod (7). The storage cavity (302) is opened in the cavity (301). The second L-shaped block (11) is slidably installed in the storage cavity (302), and the second L-shaped block (11) is driven to move by the telescopic component. When the telescopic component drives the second L-shaped block (11) to move into the cavity (301), the first spring (8) pushes the insertion rod (7). The first L-shaped block (10) moves toward the through hole (502) so that the first L-shaped block (10) and the second L-shaped block (11) engage. At this time, the inclined side (701) is located in the connecting groove (501). When the insertion rod (7) is squeezed into the cavity (301), the first L-shaped block (10) moves away from the second L-shaped block (11). At this time, the telescopic component drives the second L-shaped block (11) to move into the storage cavity (302). Then the first spring (8) pushes the insertion rod (7) to pass through the through hole (502), the first opening (601) and the threaded groove (503) in sequence.

6. The automated assembly platform for solar photovoltaic frames according to claim 5, characterized in that, The telescopic assembly includes a second spring (12) and a second extension rod (13). The second L-shaped block (11) is connected to the storage cavity (302) through the second spring (12), and the preload of the second spring (12) causes the second L-shaped block (11) to move toward the storage cavity (302). The second extension rod (13) passes through the connector (3) and is fixedly connected to the second L-shaped block (11). One end of the second extension rod (13) is located outside the connector (3). The second extension rod (13) is slidably connected to the connector (3). When the insertion rod (7) is squeezed into the cavity (301), the first L-shaped block (10) moves away from the second L-shaped block (11). At this time, the preload of the second spring (12) causes the second L-shaped block (11) to move into the storage cavity (302).
