Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic frames, and in particular to an automatic assembly platform for solar photovoltaic frames. Background Art

[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 shown a rapid expansion in market size. 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 is composed of four profiles (usually aluminum alloy) connected by angle brackets to form a rectangular frame. It needs to process four sets of profiles, four angle brackets and connecting bolts and other multiple parts for collaborative assembly. Manual operation requires frequent switching of tools and workstations, and single frame assembly takes a long time. Specifically, the assembly process of the photovoltaic frame includes the cutting of frame profiles, the preparation of corner codes, the positioning and alignment of the frame, and the insertion of corner codes. Among them, the positioning and alignment of the frame is a particularly critical step, which requires workers to manually or use simple tooling to accurately place the cut frame profiles on the workbench to ensure that the docking end faces of each profile can be closely aligned, laying a solid foundation for subsequent connection work. However, due to the complexity of the frame components, this step is extremely cumbersome to operate, which is not only time-consuming and labor-intensive, but also difficult to ensure accuracy, making it difficult to effectively guarantee product quality. Based on this, the present invention purposely provides a solar photovoltaic frame automated assembly platform that can improve the automation level and efficiency of photovoltaic frame assembly. Summary of the invention

[0004] The purpose of the present invention is to provide a solar photovoltaic frame automated assembly platform to address the deficiencies in the prior art and to solve the technical problems in the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A solar photovoltaic frame automated assembly platform, comprising four splicing frames, four corner brackets and a plurality of screws, each of the splicing frames is provided with a connecting groove at both ends, a through hole and a threaded groove are provided in the connecting groove, the corner bracket is slidably connected to the connecting groove, each of the corner bracket is provided with a first opening and a second opening at both ends, the first opening is far away from the corner of the corner bracket, and the second opening is close to the corner of the corner bracket, and also comprises an assembly platform, and the assembly platform is provided with four mounting plates corresponding to the four splicing frames, the left and right mounting plates are fixedly mounted on the assembly platform, the front and rear mounting plates are slidably mounted on the assembly platform, and the two mounting plates are driven by a driving component to move toward each other; A clamping component for clamping and fixing the splicing frame is arranged on the mounting plate; An automatic robotic arm is arranged at each of the four corners of the assembly platform; A pre-locking component is arranged on the mounting plate. When the driving component drives the front and rear mounting plates to move away from each other, at this time, the four automatic robotic arms respectively insert the four corner codes into the connecting grooves on the front and rear splicing frames. When the first opening is aligned with the through hole, the pre-locking component locks the four corner codes with the front and rear splicing frames. Then, the driving component drives the front and rear mounting plates to move closer to each other. At this time, the four corner codes are inserted into the connecting grooves on the left and right splicing frames. When the first opening is aligned with the through hole, the pre-locking component locks the four corner codes with the four splicing frames.

[0006] As a further solution of the present invention: The clamping component includes a sliding plate and two connecting pieces. The two connecting pieces are respectively arranged at both ends of the mounting plate, and the two connecting pieces are symmetrically arranged. The sliding plate is slidably mounted on the mounting plate, and the sliding plate is driven by a driving source built in the mounting plate to move. The splicing frame is located between the two connecting pieces and the sliding plate. When the driving source drives the sliding plate to move towards the connecting piece, the sliding plate will press the splicing frame against the connecting piece.

[0007] As a further solution of the present invention: The pre-locking component includes a plug rod, a first spring and a first extension rod. A cavity is opened in the connecting piece. The plug rod is slidably mounted in the cavity. The plug rod is connected to the cavity through the first spring, and the pre-tightening force of the first spring enables the plug rod to pass through the through hole and insert into the connecting groove. The first extension rod is slidably mounted on the connecting piece. 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 connecting piece. When the first opening is aligned with the through hole, the plug rod passes through the first opening and inserts into the threaded groove.

[0008] As a further solution of the present invention: The plug rod is provided with a bevel edge, and a limiting component is arranged in the cavity. The limiting component is connected to the plug rod. Before the corner code is inserted into the connecting groove, the limiting component restricts the position of the plug rod so that the bevel 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 bevel edge, and as the corner code is inserted, the corner code and the bevel edge are in sliding fit, and the plug rod is squeezed to move into the cavity.

[0009] As a further solution 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 the second L-shaped block is driven by the telescopic component to move. When the telescopic component drives the second L-shaped block to move into the cavity, and the first spring pushes the insertion rod towards the through hole, so that the first L-shaped block is clamped with the second L-shaped block. At this time, the hypotenuse is located in the connection groove. When the insertion rod is squeezed and moves 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, and 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 solution of the present invention: The telescopic component 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 pre-tightening force of the second spring makes the second L-shaped block move towards the receiving cavity. The second extension rod penetrates through the connecting piece and is fixedly connected to the second L-shaped block, and one end of the second extension rod is located outside the connecting piece. The second extension rod is slidably connected to the connecting piece. When the insertion rod is squeezed and moves into the cavity, the first L-shaped block moves away from the second L-shaped block. At this time, the pre-tightening force of the second spring makes the second L-shaped block move into the receiving cavity.

[0011] As a further solution of the present invention: Two slots are opened on each mounting plate, and a plug is fixedly installed on each connecting piece. The plug is slidably inserted into the slot.

[0012] As a further solution 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 the present invention: 1. In the present invention, by first locking the four corner codes with the front and rear splicing frames, then establishing the connection between the four corner codes and the left and right splicing frames through the movement of the front and rear splicing frames, and then restricting the splicing frames by the clamping component, the rectangular structure surrounded by the four splicing frames can be easily removed, and the corner codes are not completely inserted into the splicing frames, which makes a relatively large space reserved in the middle of the rectangle surrounded by the four splicing frames. When entering the process of installing the photovoltaic panel on the frame, the photovoltaic panel can be directly placed in the space surrounded by the four splicing frames. At this time, there is still a certain redundant space between the photovoltaic panel and the component splicing frame, reducing the difficulty and complexity of the four splicing frames and the subsequent installation of the photovoltaic panel; 2. In the present invention, when the corner code is inserted into the connection groove, the edge of the insertion end of the corner code abuts against the inclined edge, and as the corner code is inserted, the corner code and the inclined edge are in sliding fit, squeezing the insertion rod to move into the cavity. Subsequently, the insertion rod will abut against the surface of the corner code. As the corner code continues to be inserted, when the first opening aligns with the through hole, the first spring will push the insertion rod through the through hole, the second opening and into the threaded groove, thereby completing the locking of the corner code. In this way, the self-locking function can be realized, eliminating the step of moving the first extension rod and improving the assembly efficiency. 3. In the present invention, the connecting member can be inserted into the slot through the insertion block. In this way, after the preliminary assembly of the four splicing frames and the four corner codes is completed, the splicing frames together with the connecting member are moved. At this time, the insertion block separates from the slot, which is beneficial for moving and transporting the assembled splicing frames. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figure 1-Figure 8 As shown, the present invention is an automated assembly platform for a solar photovoltaic frame, including four splicing frames 5, four corner codes 6, and a plurality of screws. Each end of each splicing frame 5 is provided with a connection groove 501, and a through hole 502 and a threaded groove 503 are provided in the connection groove 501. The corner code 6 is slidably connected to the connection groove 501. Each end of each corner code 6 is provided with a first opening 601 and a second opening 602. The first opening 601 is away from the corner of the corner code 6, and the second opening 602 is close to the corner of the corner code 6. It also includes an assembly platform 1. Four mounting plates 2 corresponding to the four splicing frames 5 are arranged on the assembly platform 1. 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, and the two mounting plates 2 are driven by a driving component to move towards each other; A clamping component for clamping and fixing the splicing frame 5 is arranged on the mounting plate 2; An automatic robotic arm 101 is arranged at each of the four corners of the assembly platform 1; A pre-locking component is arranged on the mounting plate 2. When the driving component drives the two front and rear mounting plates 2 to move away from each other, at this time, the four automatic robotic arms 101 respectively insert the four corner codes 6 into the connection grooves 501 on the two front and rear splicing frames 5. When the first opening 601 is aligned with the through hole 502, the pre-locking component locks the four corner codes 6 with the two front and rear splicing frames 5. Subsequently, the driving component drives the two front and rear mounting plates 2 to move closer to each other. At this time, the four corner codes 6 are inserted into the connection grooves 501 on the two left and right splicing frames 5. When the first opening 601 is aligned with the through hole 502, the pre-locking component locks the four corner codes 6 with the four splicing frames 5.

[0019] In one case of this embodiment, the driving component can select components such as a bidirectional lead screw assembly driven by a motor, an electric cylinder, an electric telescopic rod, etc., or other mechanisms that can realize the relative movement of the two mounting plates 2. This embodiment does not specifically limit it here; it should be noted that the automatic robotic arm 101 described in the present invention is a prior art, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention.

[0020] Working principle of the present invention: the existing solar photovoltaic frame assembly is divided into frame assembly and photovoltaic panel installation in the frame, and in order to improve the efficiency of the assembly, these two processes are separated independently, such as Figure 1 As shown in the figure, the front and rear mounting plates 2 are first driven away from each other by the driving assembly, and then the four automatic mechanical arms 101 place the four splicing frames 5 on the four mounting plates 2 respectively, and the splicing frames 5 are clamped and fixed by the clamping assembly, and then the four automatic mechanical arms 101 respectively insert the four corner brackets 6 into the connecting grooves 501 on the front and rear splicing frames 5. When the first opening 601 is aligned with the through hole 502, the pre-locking assembly locks the four corner brackets 6 with the front and rear splicing frames 5. At this time, the connection between the splicing frames 5 and the corner brackets 6 is the same as Figure 7 As shown, the driving assembly then drives the front and rear mounting plates 2 to approach each other, and at this time, the four corner brackets 6 are inserted into the connecting grooves 501 on the left and right splicing frames 5. When the first opening 601 is aligned with the through hole 502, the pre-locking assembly locks the four corner brackets 6 with the four splicing frames 5, and finally forms the following Figure 8 The state shown, that is, the assembly of the photovoltaic frame is completed. At this time, the restriction of the clamping assembly on the splicing frame 5 is released, and the four splicing frames 5 forming a rectangle can be removed. At this time, the four splicing frames 5 are connected to the corner code 6 and the pre-locking assembly, and the structure of the four splicing frames 5 is stable, which can be convenient for transportation and transfer. It is worth noting that the corner code 6 is not fully inserted into the connecting groove 501, so that there is a large space in the middle of the rectangle surrounded by the four splicing frames 5. When the four splicing frames 5 come to assemble the photovoltaic panel, the photovoltaic panel can be directly placed between the four splicing frames 5. At this time, there is still a large redundant space between the photovoltaic panel and the splicing frame 5. At this time, the lock of the pre-locking assembly is released, and the four splicing frames 5 are pushed to the photovoltaic panel in the middle to complete the entire assembly task.

[0021] like Figure 1-Figure 2 As shown, as 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 arranged at both ends of the mounting plate 2, and the two connecting members 3 are symmetrically arranged, the sliding plate 4 is slidably installed on the mounting plate 2, and the sliding plate 4 is driven to move by a driving source built into the mounting plate 2, the splicing frame 5 is located between the two connecting members 3 and the sliding plate 4, and when the driving 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 case of this embodiment, the driving source may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving reciprocating motion, which is not specifically limited in this embodiment.

[0023] In actual application of this embodiment, the splicing frame 5 is placed between the two connecting parts 3 and the sliding plate 4. When the driving source drives the sliding plate 4 to move toward the connecting part 3, the sliding plate 4 will abut the splicing frame 5 against the connecting part 3, thereby completing the clamping and fixing effect on the splicing frame 5. The sliding plate 4 is movable, so it can adapt to splicing frames 5 of different sizes.

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

[0025] In actual application of this embodiment, the insertion rod 7 sliding in the cavity 301 can pass through the through hole 502. Therefore, after the angle code 6 is inserted into the connecting groove 501, the first extension rod 9 is moved so that the insertion rod 7 compresses the first spring 8 and moves it 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 insertion rod 7 to pass through the through hole 502, the second opening 602 and insert into the threaded groove 503, thereby completing the locking of the angle code 6 and preventing the angle code 6 from continuing to be inserted.

[0026] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, a bevel 701 is provided on the insertion rod 7, and a limiting component is provided in the cavity 301, and the limiting component is connected to the insertion rod 7. Before the angle code 6 is inserted into the connecting groove 501, the limiting component limits the position of the insertion rod 7 so that the bevel 701 is located in the connecting groove 501. When the angle code 6 is inserted into the connecting groove 501, the edge of the insertion end of the angle code 6 abuts against the bevel 701, and as the angle code 6 is inserted, the angle code 6 slides with the bevel 701 to squeeze the insertion rod 7 into the cavity 301.

[0027] In actual application of this embodiment, the position of the insertion rod 7 is limited by the limiting component, so that the bevel 701 is located in the connecting groove 501, so that when the angle code 6 is inserted into the connecting groove 501, the edge of the insertion end of the angle code 6 abuts the bevel 701, and as the angle code 6 is inserted, the angle code 6 slides with the bevel 701 to squeeze the insertion rod 7 into the cavity 301, and then the insertion rod 7 will abut against the surface of the angle code 6. As the angle code 6 continues to be inserted, when the first opening 601 is aligned with the through hole 502, the first spring 8 will push the insertion rod 7 through the through hole 502, the second opening 602 and inserted into the threaded groove 503, thereby completing the locking of the angle code 6. In this way, the self-locking function can be achieved, the step of moving the first extension rod 9 is omitted, and the efficiency of assembly is improved.

[0028] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, the limiting assembly includes a storage cavity 302, a first L-shaped block 10, a second L-shaped block 11 and a telescopic assembly, 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 assembly, when the telescopic assembly drives the second L-shaped block 11 to move into the cavity 301, and the first spring 8 pushes the insertion rod 7 to move toward the through hole 502, so that the first L-shaped block 10 is engaged with the second L-shaped block 11, at this time the bevel 701 is located in the connecting groove 501, when the insertion rod 7 is squeezed to move into the cavity 301, the first L-shaped block 10 is 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 storage cavity 302, and 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 application, if Figure 4 As shown in the figure, for example, when the telescopic assembly drives the second L-shaped block 11 to move into the cavity 301, and the first spring 8 pushes the insertion rod 7 to move toward the through hole 502, so that the first L-shaped block 10 is engaged with the second L-shaped block 11. At this time, the bevel 701 is located in the connecting groove 501. When the insertion rod 7 is squeezed and moved into the cavity 301, the first L-shaped block 10 is 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 storage cavity 302. Subsequently, 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, Figure 5 The state shown can ensure that before the angle code 6 is inserted into the connecting groove 501, the bevel 701 can be located in the connecting groove 501, thereby cooperating with the angle code 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 Figure 1-Figure 5As shown, as 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 storage cavity 302 through the second spring 12, and the preload force 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 connecting piece 3 and is fixedly connected to the second L-shaped block 11, and one end of the second extension rod 13 is located outside the connecting piece 3, and the second extension rod 13 is slidably connected to the connecting piece 3, when the insertion rod 7 is squeezed to move into the cavity 301, the first L-shaped block 10 moves away from the second L-shaped block 11, and at this time the preload force of the second spring 12 causes the second L-shaped block 11 to move into the storage cavity 302.

[0031] In practical application, if Figure 4 As shown in the example, after the angle code 6 is inserted into the connecting groove 501, the angle code 6 will squeeze the insertion rod 7 after abutting against the bevel 701, so that the insertion rod 7 compresses the first spring 8 and moves 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 squeezed and abuts on the surface of the angle code 6 to slide. At this time, the first L-shaped block 10 and the second L-shaped block 11 are completely separated, and 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. Subsequently, 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 turn. 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, eliminating the step and time of shrinking the second L-shaped block 11 through operation, which is more convenient for assembling the splicing frame 5.

[0032] like Figure 1-Figure 2 As shown, as a preferred embodiment of the present invention, two slots 201 are provided on each of the mounting plates 2 , and an insert block 303 is fixedly mounted on each of the connectors 3 , and the insert block 303 is slidably inserted into the slot 201 .

[0033] In actual application of this embodiment, the connecting member 3 can be inserted into the slot 201 through the plug block 303. After the preliminary assembly of the four splicing frames 5 and the four corner codes 6 is completed, the splicing frames 5 are moved together with the connecting member 3. At this time, the plug block 303 is separated from the slot 201, which is convenient for moving and transporting the assembled splicing frames 5.

[0034] like Figure 1-Figure 2 As shown, as 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 with the thread groove 503 .

[0035] In actual application of this embodiment, after the four splicing frames 5 are pushed toward the middle photovoltaic panel to complete the entire assembly task, the second opening 602 is aligned with the through hole 502. At this time, a screw is passed through the through hole 502 and the second opening 602, and the screw is threadedly connected to the thread groove 503, so that the final fixation can be completed.

[0036] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
