Description

Technical Field

[0001] This invention relates to the field of microinverter technology, specifically an auxiliary positioning device for microinverter assembly. Background Technology

[0002] A micro inverter generally refers to an inverter in a photovoltaic power generation system with a power output of less than or equal to 1000 watts and equipped with a module-level MPPT. Its full name is micro-photovoltaic grid-connected inverter. The term "micro" is relative to traditional centralized inverters. Traditional photovoltaic inverters connect all the direct current (DC) generated by photovoltaic cells under sunlight in series and parallel, then use a single inverter to convert the DC to AC and connect it to the grid. Micro inverters, on the other hand, invert each module individually. Their advantage lies in the ability to independently control each module's MPPT, significantly improving overall efficiency. They also avoid the problems associated with centralized inverters, such as high DC voltage, poor performance in low light conditions, and the "weakest link" effect.

[0003] Most existing microinverters consist of a microinverter housing, a circuit board, and a cover plate. The circuit board has connectors with snap-fit ​​slots that mate with the microinverter housing. Installation is completed by tightening the screws on the circuit board. Since the circuit board has multiple screws, workers need to align it with the housing before tightening the screws, resulting in frequent and inefficient operations. Furthermore, dust accumulates on the circuit board during installation. If this dust is not cleaned during installation, it will increase the circuit board's resistance and accelerate temperature rise, thus reducing its lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary positioning device for assembling microinverters to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An auxiliary positioning device for assembling a micro inverter includes a base, a placement component, and a pushing component. The upper surface of the base is provided with a worktable for placing the micro inverter housing. The worktable is fixedly connected to the base. The placement component is located at the top of the base and is used to store the circuit board. The top of the placement component is provided with a pushing component, which is used to push the circuit board to move towards the worktable.

[0007] A microinverter is assembled using a microinverter housing, circuit board, and cover plate. The circuit board is placed inside the microinverter housing and has bolt holes. The circuit board is connected to the microinverter housing by bolts. The base serves as the basic structure. The worktable has a hollow cavity structure for placing the microinverter housing. The placement component is used to place the circuit board, and the pushing component is used to push the circuit board on the placement component. Specifically, the pushing component pushes the connector on the circuit board so that the connector is assembled with the microinverter housing. The connector has a snap-fit ​​groove that engages with the microinverter housing and can also be pushed by external structures.

[0008] Furthermore, the placement component includes a column and a snap-fit ​​block. The column is located on the upper surface of the base, and a plate is provided at the top of the column. A notch is opened in the middle of the plate, and the snap-fit ​​block is located at the notch. The snap-fit ​​block is bolted to the inner wall of the plate. A groove A is opened on the snap-fit ​​block, and an extension block is provided in the groove A. The extension block is fixedly connected to the inner wall of the groove A. A protrusion A is provided at one end of the extension block, and the protrusion A is fixedly connected to the extension block.

[0009] The column serves as a support structure for the components. The plate is located on the workbench. There are two snap-fit ​​blocks, located at both ends of the inner wall of the snap-fit ​​blocks. The groove A of the connector is used to place the connector in the circuit board. The extension block and the protrusion A are used to limit the snap-fit ​​groove on the connector. The circuit board is fixed on the plate by the snap-fit ​​blocks. The groove A on the snap-fit ​​blocks is set according to the connector position of the circuit board. The snap-fit ​​blocks are connected to the plate by bolts. The snap-fit ​​blocks can be replaced according to the model of the circuit board to restrict different circuit boards.

[0010] Furthermore, the pushing component includes a support column A and a housing. The support column A is located on the upper surface of the base. The top of the support column A is provided with a housing. A threaded rod is provided inside the housing. The threaded rod is fixedly connected to the top of the housing. A pushing plate is provided inside the housing. A driving push rod is provided inside the housing. The fixed end of the driving push rod is fixedly connected to the inner wall of the housing. The output end of the driving push rod is fixedly connected to the pushing plate. A through hole A is provided on the pushing plate. The through hole A cooperates with the threaded rod.

[0011] Support column A serves as the support structure for the push assembly, the housing serves as the main structure of the push assembly, the threaded rod is perpendicular to the inside of the housing, the push plate is used to push the circuit board to move, the drive push rod is perpendicular to the inside of the housing, and the drive push rod serves as the power source to push the push plate to move. The push plate moves up and down, and the space inside the through hole A is used to place the threaded rod.

[0012] Furthermore, the bottom of the push plate is provided with a dust removal component for cleaning dust on the circuit board. A groove B is provided at the bottom of the push plate, and a grid plate is provided on the groove B. The grid plate is bolted to the push plate.

[0013] During transportation, dust accumulates on the surface of the circuit board. If the dust is not cleaned during installation, it will increase the resistance value during subsequent use, thereby reducing the service life of the device. The dust removal component is used to blow the dust off the surface of the circuit board when pushing it. The grid has a structure with multiple ventilation holes for airflow.

[0014] Furthermore, the dust removal assembly includes a rotating ring and a fan blade. The inner wall of the rotating ring is threaded, and the rotating ring is sleeved on the threaded rod. The rotating ring is located in the groove B. The outer wall of the rotating ring is provided with a fan blade, which is fixedly connected to the rotating ring. The grid plate has a through hole B, and a bearing A is provided in the through hole B. The outer ring of the bearing A is fixedly connected to the inner wall of the grid plate, and the inner ring of the bearing A is fixedly connected to the rotating ring.

[0015] The threads on the inner wall of the rotating ring engage with the threaded rod. Because the rotating ring is located in groove B and is also connected to the inner ring of bearing A, when the push plate moves, the push plate will drive the grid plate to move. The grid plate is fixedly connected to the outer ring of bearing A. The movement of the grid plate will drive the bearing A to move, and the bearing A will drive the rotating ring to move. Because the threads on the inner wall of the rotating ring engage with the threaded rod and are connected to the inner ring of bearing A, the rotating ring will start to rotate. The rotating ring drives the fan blades to rotate, thereby generating wind force. The wind force is downward, cleaning the dust on the circuit board.

[0016] Furthermore, the top of the push plate is provided with a rotating assembly, which includes a mounting block located at the top of the push plate. A bearing B is provided in the middle of the mounting block. The mounting block is fitted onto a threaded rod. The bottom end of the mounting block is fixedly connected to the top of the push plate. A main gear is fitted onto the threaded rod. The main gear has threads inside. The main gear is fixedly connected to the inner ring of the bearing B. The top of the push plate is provided with a driven gear, which is rotatably connected to the push plate. The driven gear meshes with the tooth edge of the main gear.

[0017] The mounting block at the top of the push plate is used to install the driven gear. Since the main gear is fixedly connected to the inner ring of bearing B, and the outer ring of bearing B is fixedly connected to the inner wall of the mounting block, when the push plate moves, the push plate will drive the mounting block to move, and the mounting block will drive the main gear to move. Since the thread inside the main gear meshes with the threaded tube, and the main gear is connected to the inner ring of bearing B, the main gear will rotate as the mounting block moves. The rotation of the main gear drives the driven gear to rotate, thus realizing that several driven gears are driven to rotate during the movement of the push plate. The number of driven gears is consistent with the number of threaded holes on the circuit board.

[0018] Furthermore, the push plate has a through groove, and a transmission assembly is provided on the through groove. The transmission assembly includes a transmission rod, which is located in the through groove. A screwdriver head is provided at the bottom end of the transmission rod, which is located at the bottom end of the push plate. A connecting plate is provided at the top end of the transmission rod, and a driven belt rod is provided at the top end of the connecting plate. A main belt rod is provided at the top end of the driven gear, and the main belt rod is connected to the driven belt rod by a belt.

[0019] The number of through slots is the same as the number of threaded holes on the circuit board. When the gear rotates, it drives the main belt rod to rotate. The main belt rod drives the secondary belt rod to rotate through the belt connection. The secondary belt rod drives the connecting plate to rotate. The connecting plate drives the transmission rod to rotate. The transmission rod drives the screwdriver head to rotate, thereby cooperating with the drive push rod to make the screwdriver head tighten the screws on the circuit board. The screwdriver head rotates as the push plate moves, tightening the screws in the threaded holes on the circuit board.

[0020] Furthermore, an extension plate is provided at the bottom of the push plate, and the extension plate is fixedly connected to the push plate. A protrusion B is provided at the bottom of the extension plate.

[0021] The extension plate is used to increase the contact distance between the bump B and the connector in the circuit board. The installation position of the extension plate is on the same central axis as the groove A. When the push plate moves, it drives the extension plate to move. The extension plate drives the bump B to move. The downward movement of the bump B will push the connector on the groove A. The bump B will cooperate with the snap-fit ​​groove on the connector. Thus, the movement of the push plate will drive the circuit board to move and move the circuit board to the worktable.

[0022] Furthermore, a spring is provided at the bottom of the workbench, and bottom fixing blocks are provided at both ends of the base. The bottom fixing blocks are fixedly connected to the base, and a support column B is provided between the shell and the bottom fixing blocks.

[0023] When the worktable is under pressure, the bottom spring creates a space for movement between the worktable and the base, allowing the screwdriver head to rotate. This enables the push plate to tighten the screws on the circuit board during movement. The two ends of the support column B are bolted to the top and bottom fixing blocks to support the push assembly.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. The present invention drives the push rod to control the movement of the push plate, thereby pushing the plate to move and causing the extension plate to move. The extension plate causes the protrusion B to move. The downward movement of the protrusion B will push the connector on the groove A, and the protrusion B will cooperate with the snap-fit ​​groove on the connector. Thus, the movement of the push plate will drive the circuit board to move and move the circuit board to the worktable. When it moves to the worktable, the connector will be assembled with the micro-inverter housing.

[0026] 2. When the push plate moves, it will drive the grid plate to move. The grid plate is fixedly connected to the outer ring of bearing A. The movement of the grid plate will drive the bearing A to move. The bearing A will drive the rotating ring to move. Because the thread on the inner wall of the rotating ring is engaged with the threaded rod and connected to the inner ring of bearing A, the rotating ring will start to rotate. The rotating ring drives the fan blade to rotate, thereby generating wind force. The wind force is downward, which cleans the dust on the circuit board.

[0027] 3. When the push plate of the present invention moves, it drives the mounting block to move, which in turn drives the main gear to move. The rotation of the main gear drives the driven gear to rotate, which in turn drives the main belt rod to rotate. The main belt rod drives the driven belt rod to rotate via a belt connection, which in turn drives the connecting plate to rotate. The connecting plate drives the transmission rod to rotate, which in turn drives the screwdriver head to rotate. This, in conjunction with the drive push rod, causes the screwdriver head to rotate on the screws on the circuit board. The screwdriver head rotates as the push plate moves, tightening the screws in the threaded holes on the circuit board. Attached Figure Description

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example: Figures 1-10 As shown, the present invention provides a technical solution for an auxiliary positioning device for assembling a microinverter.

[0041] An auxiliary positioning device for assembling a micro inverter includes a base 1, a placement component 2, and a pushing component 3. The upper surface of the base 1 is provided with a workbench 4 for placing the micro inverter housing. The workbench 4 is fixedly connected to the base 1. The placement component 2 is located at the top of the base 1 and is used to store the circuit board. The top of the placement component 2 is provided with a pushing component 3, which is used to push the circuit board to the workbench 4.

[0042] Specifically, the microinverter is assembled using a microinverter housing, a circuit board, and a cover plate. The circuit board is placed inside the microinverter housing and has bolt holes. The circuit board is connected to the microinverter housing by bolts. The base 1 serves as the basic structure. The workbench 4 has a hollow cavity structure for placing the microinverter housing. The placement component 2 is used to place the circuit board, and the pushing component 3 is used to push the circuit board on the placement component 2. Specifically, the pushing component 3 pushes the connector on the circuit board so that the connector is assembled with the microinverter housing. Each connector has a snap-fit ​​groove that engages with the microinverter housing and can also be pushed by an external structure.

[0043] like Figure 1 , Figure 2As shown, the placement component 2 includes a column 21 and a snap-fit ​​block 22. The column 21 is located on the upper surface of the base 1. A plate 23 is provided at the top of the column 21. A notch 231 is provided in the middle of the plate 23. The snap-fit ​​block 22 is located at the notch 231. The snap-fit ​​block 22 is bolted to the inner wall of the plate 23. A groove A221 is provided on the snap-fit ​​block 22. An extension block 24 is provided in the groove A221. The extension block 24 is fixedly connected to the inner wall of the groove A221. A protrusion A25 is provided at one end of the extension block 24. The protrusion A25 is fixedly connected to the extension block 24.

[0044] Specifically, the column 21 serves as the supporting structure for the component 2, the plate 23 is located on the workbench 4, and there are two snap-fit ​​blocks 22, located at both ends of the inner wall of the snap-fit ​​block 22. The groove A221 of the connector is used to place the connector in the circuit board, and the extension block 24 and the protrusion A25 are used to limit the snap-fit ​​groove on the connector. The circuit board is restricted to the plate 23 by the snap-fit ​​block 22. The groove A221 on the snap-fit ​​block 22 is set according to the connector position of the circuit board, and the snap-fit ​​block 22 and the plate 23 are connected by bolts. The snap-fit ​​block 22 can be replaced according to the model of the circuit board to restrict different circuit boards.

[0045] like Figures 4-9 As shown, the pushing component 3 includes a support column A31 and a housing 32. The support column A31 is located on the upper surface of the base 1. The housing 32 is provided at the top of the support column A31. A threaded rod 33 is provided inside the housing 32. The threaded rod 33 is fixedly connected to the top of the inside of the housing 32. A pushing plate 34 is provided inside the housing 32. A driving push rod 35 is provided inside the housing 32. The fixed end of the driving push rod 35 is fixedly connected to the inner wall of the housing 32. The output end of the driving push rod 35 is fixedly connected to the pushing plate 34. A through hole A341 is provided on the pushing plate 34. The through hole A341 cooperates with the threaded rod 33.

[0046] Specifically, the support column A31 serves as the support structure for the push assembly 3, the housing 32 serves as the main structure of the push assembly 3, the threaded rod 33 is perpendicular to the inside of the housing 32, the push plate 34 is used to push the circuit board to move, the drive push rod 35 is perpendicular to the inside of the housing 32, and the drive push rod 35 serves as a power source to push the push plate 34 to move. The push plate 34 moves up and down, and the space inside the through hole A341 is used to place the threaded rod 33.

[0047] like Figure 5 , Figure 7 The push plate 34 shown has a dust cleaning component 36 at its bottom for cleaning dust on the circuit board. The bottom of the push plate 34 has a groove B342, and a grid plate 37 is provided on the groove B342. The grid plate 37 is bolted to the push plate 34.

[0048] Specifically, dust accumulates on the surface of the circuit board during transportation. If the dust is not cleaned during installation, it will increase the resistance value during subsequent use, thereby reducing the service life of the device. The dust removal component 36 is used to blow the dust off the surface of the circuit board when pushing it. The grid plate 37 has a structure with multiple ventilation holes for airflow.

[0049] like Figure 5 , Figure 7 As shown, the dust removal assembly 36 includes a rotating ring 361 and a fan blade 362. The inner wall of the rotating ring 361 is threaded, and the rotating ring 361 is sleeved on the threaded rod 33. The rotating ring 361 is located in the groove B342. The outer wall of the rotating ring 361 is provided with the fan blade 362, and the fan blade 362 is fixedly connected to the rotating ring 361. The grid plate 37 has a through hole B371, and a bearing A363 is provided in the through hole B371. The outer ring of the bearing A363 is fixedly connected to the inner wall of the grid plate 37, and the inner ring of the bearing A363 is fixedly connected to the rotating ring 361.

[0050] Specifically, the threads on the inner wall of the rotating ring 361 engage with the threaded rod 33. Because the rotating ring 361 is located in the groove B342 and is also connected to the inner ring of the bearing A363, when the push plate 34 moves, the push plate 34 will drive the grid plate 37 to move. The grid plate 37 is fixedly connected to the outer ring of the bearing A363. The movement of the grid plate 37 will drive the bearing A363 to move, and the bearing A363 will drive the rotating ring 361 to move. Because the threads on the inner wall of the rotating ring 361 engage with the threaded rod 33 and are connected to the inner ring of the bearing A363, the rotating ring 361 will start to rotate. The rotating ring 361 drives the fan blade 362 to rotate, thereby generating wind force. The wind force is downward, cleaning the dust on the circuit board.

[0051] like Figure 4 , Figure 6 , Figure 8 As shown, the top of the push plate 34 is provided with a rotating assembly 38, which includes a mounting block 381. The mounting block 381 is located at the top of the push plate 34, and a bearing B382 is provided in the middle of the mounting block 381. The mounting block 381 is fitted onto a threaded rod 33, and the bottom end of the mounting block 381 is fixedly connected to the top of the push plate 34. A main gear 383 is fitted onto the threaded rod 33, and the main gear 383 has threads inside. The main gear 383 is fixedly connected to the inner ring of the bearing B382. The top of the push plate 34 is provided with a driven gear 384, which is rotatably connected to the push plate 34. The driven gear 384 meshes with the teeth of the main gear 383.

[0052] Specifically, the mounting block 381 at the top of the push plate 34 is used to mount the driven gear 384. Since the main gear 383 is fixedly connected to the inner ring of the bearing B382, and the outer ring of the bearing B382 is fixedly connected to the inner wall of the mounting block 381, when the push plate 34 moves, the push plate 34 will drive the mounting block 381 to move, and the mounting block 381 will drive the main gear 383 to move. Since the thread inside the main gear 383 meshes with the threaded tube, and the main gear 383 is connected to the inner ring of the bearing B382, the main gear 383 will rotate as the mounting block 381 moves. The rotation of the main gear 383 drives the driven gear 384 to rotate, thereby driving several driven gears 384 to rotate during the movement of the push plate 34. The number of driven gears 384 is consistent with the number of threaded holes on the circuit board.

[0053] like Figure 5 , Figure 7 , Figure 10 As shown, the push plate 34 has a through groove 343, and a transmission assembly 39 is provided on the through groove 343. The transmission assembly 39 includes a transmission rod 391, which is located in the through groove 343. A screwdriver head 392 is provided at the bottom end of the transmission rod 391, which is located at the bottom end of the push plate 34. A connecting plate 393 is provided at the top end of the transmission rod 391, and a driven belt rod 394 is provided at the top end of the connecting plate 393. A main belt rod 395 is provided at the top end of the driven gear 384, and the main belt rod 395 is connected to the driven belt rod 394 by a belt.

[0054] Specifically, the number of through slots 343 is consistent with the number of threaded holes on the circuit board. When the driven gear 384 rotates, it drives the main belt rod 395 to rotate. The main belt rod 395 drives the driven belt rod 394 to rotate through the belt connection. The driven belt rod 394 drives the connecting plate 393 to rotate. The connecting plate 393 drives the transmission rod 391 to rotate. The transmission rod 391 drives the screwdriver head 392 to rotate, thereby cooperating with the drive push rod 35 to make the screwdriver head 392 tighten the screws on the circuit board. The screwdriver head 392 rotates as the push plate 34 moves, tightening the screws in the threaded holes on the circuit board.

[0055] like Figure 4 As shown, the bottom end of the push plate 34 is provided with an extension plate 5, which is fixedly connected to the push plate 34, and the bottom end of the extension plate 5 is provided with a protrusion B6.

[0056] Specifically, the extension plate 5 is used to increase the contact distance between the bump B6 and the connector in the circuit board. The installation position of the extension plate 5 is on the same central axis as the groove A221. As the push plate 34 moves, it drives the extension plate 5 to move. The extension plate 5 drives the bump B6 to move. The downward movement of the bump B6 will push the connector on the groove A221, and the bump B6 will cooperate with the snap-fit ​​groove on the connector. Thus, the movement of the push plate 34 will drive the circuit board to move and move the circuit board to the worktable 4.

[0057] like Figure 1 , Figure 3 As shown, the bottom of the workbench 4 is provided with a spring 7, and the two ends of the base 1 are provided with bottom fixing blocks 8. The bottom fixing blocks 8 are fixedly connected to the base 1, and a support column B9 is provided between the housing 32 and the bottom fixing blocks 8.

[0058] Specifically, when the workbench 4 is under pressure, due to the bottom spring 7, there is a space for movement between the workbench 4 and the base 1, which provides room for the screwdriver head 392 to rotate, so that the push plate 34 can tighten the screws on the circuit board during the movement process. The two ends of its support column B9 are bolted to the housing 32 and the bottom fixing block 8 to support the push assembly 3.

[0059] Working Principle: The user places the micro-inverter housing on the workbench 4, then places the circuit board into the groove A221 through the snap-fit ​​slot on the connector, positioning the circuit board on the placement assembly 2. The drive push rod 35 then moves the push plate 34. During this movement, the rotating ring 361 and the main gear 383, due to their engagement with the threaded rod 33, rotate along with the push plate 34. The rotation of the rotating ring 361 drives the fan blades 362, generating downward airflow to clean dust from the circuit board. The rotation of the main gear 383 drives the driven gear 384, which in turn drives the main belt rod 395. The main belt rod 395 then... The belt drive rotates the belt rod 394, which in turn drives the connecting plate 393 to rotate. The connecting plate 393 drives the transmission rod 391 to rotate, which in turn drives the screwdriver head 392 to rotate. This, in turn, works with the drive push rod 35 to tighten the screws on the circuit board. As the push plate 34 moves downward, the protrusion B6 engages with the snap-fit ​​groove on the connector. The movement of the push plate 34 moves the circuit board onto the worktable 4, allowing the connector to assemble with the micro-inverter housing within the worktable 4. The screwdriver head 392 within the push plate 34 rotates the screws on the circuit board, causing the screws to mesh with the micro-inverter housing, thus completing the assembly of the circuit board and the micro-inverter housing.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of the invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the invention, and no reference numerals in the claims should be regarded as limiting the scope of the claims.
