Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic inductor manufacturing processes, and particularly to a photovoltaic inductor manufacturing equipment and method. Background Technology

[0002] Photovoltaic inductors are common components in the photovoltaic field. During production, enameled wire needs to be wound around a toroidal winding frame to form the required coil.

[0003] Due to limitations in the winding process, the enameled wire cannot be completely fitted to the winding frame. That is, at the corners of the cross-section of the winding frame, the enameled wire contacts the winding frame at four points, while at other locations, there are gaps between the enameled wire and the winding frame, making the enameled wire appear arched.

[0004] Since the coil also needs to be assembled into the mounting box, the arched enameled wire will occupy the assembly gap and affect the assembly operation.

[0005] To address this, it is also necessary to reshape the external shape of the coil. Technical solutions could include an inductor coil shaping device with authorization announcement number CN215770850U, a shaping and pressure holding mechanism with authorization announcement number CN220569541U, and an inductor shaping device with authorization announcement number CN220439402U, to achieve both external and internal shaping of the coil.

[0006] However, existing cosmetic surgery methods are inefficient and lack comprehensive functions. Summary of the Invention

[0007] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a photovoltaic inductor production equipment that can improve shaping efficiency and has complete shaping functions.

[0008] The present invention also proposes a method for producing photovoltaic inductors that is applied to the aforementioned photovoltaic inductor production equipment.

[0009] A photovoltaic inductor manufacturing apparatus according to a first aspect of the present invention, the manufacturing apparatus comprising:

[0010] An external shaping module includes a first conveying device and an external shaping device. The first conveying device includes a first conveying chain and a rod disposed on the first conveying chain. The rod is fitted with a rotating ring, and the photovoltaic inductor is fitted on the outside of the rotating ring. The external shaping device includes a forward pressing conveyor belt located on one side of the first conveying chain and a reverse pressing conveyor belt located on the other side of the first conveying chain. When the rod passes between the forward pressing conveyor belt and the reverse pressing conveyor belt, the forward pressing conveyor belt and the reverse pressing conveyor belt cooperate to twist and shape the radial outer surface of the photovoltaic inductor.

[0011] The inner shaping module includes a second conveying device and an inner shaping device. The second conveying device includes a second conveying chain and a sleeve disposed on the second conveying chain. The photovoltaic inductor is fitted inside the sleeve. The inner shaping device includes a turntable and an insert rod eccentrically disposed on the turntable. When the turntable and the sleeve are concentric, the insert rod can extend into the sleeve. The insert rod is provided with an inner shaping part, which is used to abut against the radial inner surface of the photovoltaic inductor.

[0012] The end-face shaping module includes a third conveying device and an end-face shaping device. The third conveying device includes a material transfer seat and a material placement rack disposed on the material transfer seat. The material placement rack is provided with multiple material placement cavities, which are arranged in multiple rows and columns. The material placement cavities are used to place and position the photovoltaic inductor. The photovoltaic inductor is in an upright state. The end-face shaping device includes an upper shaping frame and a lower shaping frame. The lower shaping frame rises to support the material placement rack, and the upper shaping frame descends to press the end face of the photovoltaic inductor.

[0013] A photovoltaic inductor production device according to an embodiment of the present invention has at least the following beneficial effects:

[0014] This invention, by setting an outer shaping module, an inner shaping module, and an end-face shaping module, can achieve shaping treatment of the radial outer surface, radial inner surface, and end face of the photovoltaic inductor, making the shape of the photovoltaic inductor close to the design requirements. On the one hand, it avoids the impact of shape differences on assembly and improves assembly convenience. On the other hand, the coil arrangement of the photovoltaic inductor is closer to the design state. Therefore, the performance of the photovoltaic inductor is closer to the theoretical effect, which can meet the high-quality requirements of customers.

[0015] This invention sets up a first conveyor chain with inserts, so that the photovoltaic inductor can be fitted onto the outside of the inserts. Through the continuous conveying of the first conveyor chain, the photovoltaic inductor can be automatically supplied, which helps to realize the automated and continuous external shaping.

[0016] This invention incorporates a rotating ring on the insertion rod, which allows the rotating ring to rotate synchronously when the photovoltaic inductor rotates. This reduces relative friction and wear, which is beneficial for protecting the coil. At the same time, it also facilitates full-circumference shaping of the radial outer surface of the photovoltaic inductor, improving the completeness of the shaping and reducing blind spots in the external shaping.

[0017] This invention, by setting up a forward pressing conveyor belt and a reverse pressing conveyor belt, allows the photovoltaic inductor to be uniformly shaped around its radial outer surface when the insert rod passes between them. This ensures that the photovoltaic inductor moves with the insert rod and the first conveyor chain while simultaneously rotating, achieving uniform shaping of the entire radial outer surface of the photovoltaic inductor. This avoids omissions in the shaping process and improves the shaping quality.

[0018] At the same time, it also enables the first conveyor chain to transport materials over long distances, reducing or even eliminating stoppages, which helps improve shaping efficiency.

[0019] By setting up a second conveyor chain and a sleeve, the photovoltaic inductor can be fitted inside the sleeve. Through the continuous conveying of the second conveyor chain, the photovoltaic inductor can be automatically supplied, which helps to realize the automated and continuous external shaping.

[0020] The bushing can improve the positioning accuracy by limiting the outer side of the photovoltaic inductor, and facilitate the automated shaping of the radial inner surface of the photovoltaic inductor, reducing the difficulty of shaping.

[0021] This invention uses a turntable and an eccentrically positioned insert rod on the turntable. When the turntable is concentric with the sleeve, the insert rod can extend into the sleeve. Then, the turntable is rotated, and the inner shaping part of the insert rod abuts against different positions on the radial inner surface of the photovoltaic inductor, thereby achieving full circumferential shaping of the inner surface, improving the integrity of the shaping, and reducing the blind zone of the inner shaping.

[0022] Meanwhile, the bushing can uniformly limit the outer side of the photovoltaic inductor to withstand the internal shaping force and prevent the turntable from spinning idly.

[0023] This invention, by setting up a material transfer platform and a material placement rack, provides a material placement rack with multiple material placement chambers arranged in multiple rows and columns. This facilitates the placement of multiple photovoltaic inductors on the material placement rack. Then, the material transfer platform moves the material placement rack to the end-face shaping device, allowing the end-face shaping of multiple photovoltaic inductors to be completed with a single press, thus improving the end-face shaping efficiency. At the same time, it also keeps the loading and unloading operations or work away from the end-face shaping device, improving the safety of the end-face shaping process.

[0024] At the same time, the end face shaping of multiple photovoltaic inductors can be completed in one press, which also helps to distribute the end face shaping force evenly. That is, a large force is divided into multiple smaller forces, which can not only meet the end face shaping needs, but also reduce the difficulty of equipment manufacturing and reduce manufacturing costs.

[0025] This invention, by setting up an upper shaping frame and a lower shaping frame, wherein the lower shaping frame rises to support the material placement frame, and the upper shaping frame descends to press the end face of the photovoltaic inductor, thus reducing the squeezing between the material placement frame and the material transfer seat, reducing the stress on the guide rail, and making the equipment more durable, also allows the lower and upper shaping frames to press the end face of the photovoltaic inductor with a set pressure, reducing the risk of damage to the photovoltaic inductor.

[0037] A photovoltaic inductor manufacturing method according to a second aspect of the present invention is applied to a photovoltaic inductor manufacturing equipment as described in any one of the claims;

[0038] The production method includes:

[0039] In the external shaping step, the photovoltaic inductor is mounted on the plug. The first conveyor chain moves the plug and the photovoltaic inductor between the forward pressing conveyor belt and the reverse pressing conveyor belt. The forward pressing conveyor belt and the reverse pressing conveyor belt squeeze the radial outer surface of the photovoltaic inductor. The forward pressing conveyor belt and the reverse pressing conveyor belt move in opposite directions, causing the photovoltaic inductor to rotate simultaneously until the photovoltaic inductor moves out from between the forward pressing conveyor belt and the reverse pressing conveyor belt, thus completing the external shaping.

[0040] In the internal shaping step, the photovoltaic inductor is inserted into the sleeve. The second conveyor chain transports the sleeve and the photovoltaic inductor to the turntable. When the turntable is concentric with the sleeve, the insertion rod extends into the sleeve. Then, the turntable rotates, and the internal shaping part abuts against different parts of the radial inner surface of the photovoltaic inductor to complete the internal shaping. Then, the insertion rod retracts, and the second conveyor chain continues to transport the sleeve and the photovoltaic inductor.

[0041] In the end-face shaping step, the photovoltaic inductor is inserted into the material placement cavity of the material placement rack. The material transfer and translation seat moves the material placement rack between the upper and lower shaping racks. The lower shaping rack rises to support the material placement rack, and the upper shaping rack descends and presses the end face of the photovoltaic inductor to complete the end-face shaping. Then, the upper and lower shaping racks are reset, and the material transfer and translation seat moves the material placement rack to the unloading position.

[0064] The following description, in conjunction with the accompanying drawings, describes a photovoltaic inductor production equipment and production method according to an embodiment of the present invention.

[0065] Reference Figures 1 to 8 The present invention aims to provide an embodiment of photovoltaic inductor production equipment, while referring to Figures 9 to 10 The present invention also aims to provide an embodiment of a photovoltaic inductor manufacturing method, wherein the photovoltaic inductor manufacturing method of the present invention is applied to... Figures 1 to 8 A type of photovoltaic inductor production equipment.

[0066] Reference Figures 1 to 8 The present invention provides a photovoltaic inductor production equipment, which aims to improve shaping efficiency and has complete shaping functions, thereby improving the production and manufacturing of photovoltaic inductors.

[0067] In this embodiment, the photovoltaic inductor production equipment mainly includes an outer shaping module 1, an inner shaping module 9, an end-face shaping module 17, and a conversion module. The conversion module is used for material transfer between the modules to improve the level of automation and reduce the impact of human factors on product quality.

[0068] Among them, reference Figure 2 and Figure 3 For the outer shaping module 1, the outer shaping module 1 is mainly used to shape the radial outer surface of the photovoltaic inductor, so that the radial outer surface of the photovoltaic inductor is approximately a cylindrical surface.

[0069] Specifically, the outer shaping module 1 includes a first conveying device 2 and an outer shaping device 3. The first conveying device 2 includes a first conveying chain 4 and a rod 5 disposed on the first conveying chain 4. The rod 5 is fitted with a rotating ring 6, and the photovoltaic inductor is fitted on the outside of the rotating ring 6. The outer shaping device 3 includes a forward pressing conveyor belt 7 located on one side of the first conveying chain 4 and a reverse pressing conveyor belt 8 located on the other side of the first conveying chain 4. When the rod 5 passes between the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8, the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 cooperate to twist and shape the radial outer surface of the photovoltaic inductor.

[0070] The present invention also provides a method for producing photovoltaic inductors, which has the above-mentioned beneficial effects.

[0071] In some specific embodiments of the present invention, at least one of the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 may be provided with a plurality of grooves 25, the extension direction of the plurality of grooves 25 being perpendicular to the conveying direction of the conveyor belt, the plurality of grooves 25 being arranged along the conveying direction of the conveyor belt, and the inner surface of the grooves 25 being used to adhere the enameled wire of the outer surface of the photovoltaic inductor.

[0072] It is easy to understand that by setting the groove 25, this embodiment can also conveniently limit the direction of coil extension, reduce the bending of the coil along the circumferential direction, reduce the mutual crushing of coils, and reduce the risk of coil damage.

[0073] In some specific embodiments of the present invention, the size and spacing of the grooves 25 can be matched with the winding design of the coil.

[0074] In some specific embodiments of the present invention, one of the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 may be connected to a drive motor 26 for moving the conveyor belt, while the other of the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 may be unpowered.

[0075] It is easy to understand that in this embodiment, by having one conveyor belt driven by the drive motor 26 while leaving the other conveyor belt in a free state, the twisting and shaping needs can be met on the one hand, and the equipment cost and space occupation can be reduced on the other hand.

[0076] In some specific embodiments of the present invention, the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 can be connected to a drive motor 26, or driven by the same motor, to increase the relative moving speed, so that the photovoltaic inductor can rotate more times when passing through the external shaping device 3, thereby improving the shaping effect.

[0077] It should be noted that the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 refer to the two conveyor belts having relative motion to meet the requirement of the photovoltaic inductor rotating a full circumference for shaping. Specifically, one conveyor belt can move while the other is stationary, or the two conveyor belts can move simultaneously but have a speed difference or move in opposite directions.

[0078] In some specific embodiments of the present invention, the external shaping device 3 may include a synchronization mechanism 27. The synchronization mechanism 27 includes a left translation seat 28, a right translation seat 29, and a proximity spring 30 that drives the left translation seat 28 and the right translation seat 29 to move closer to each other. The synchronization mechanism 27 also includes a lifting separation seat 31 and an electric cylinder 32 that drives the lifting separation seat 31 to move up and down. The lifting separation seat 31 is hinged with a left swing arm 33 and a right swing arm 34. The free end of the left swing arm 33 abuts against the left translation seat 28, and the free end of the right swing arm 34 abuts against the right translation seat 29, so that the left translation seat 28 and the right translation seat 29 are separated from each other.

[0079] It is easy to understand that, by setting the left translation seat 28, the right translation seat 29 and the approach spring 30 in this embodiment, the elastic force of the approach spring 30 can make the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 approach each other and perform clamping and shaping, so as to avoid the shaping failure caused by one of the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 failing to contact the photovoltaic inductor.

[0080] Meanwhile, by setting up the lifting separation seat 31, electric cylinder 32, left swing arm 33 and right swing arm 34, the present invention also facilitates the separation of the left translation seat 28 and the right translation seat 29, thereby increasing the distance between the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8, meeting the shaping needs of photovoltaic inductors of different specifications, and can also be used to assist the photovoltaic inductors in entering the external shaping device 3, as well as for the maintenance of the external shaping device 3.

[0081] In addition, the left swing arm 33 and the right swing arm 34 can exert a strong force on the left translation seat 28 and the right translation seat 29, preventing the left translation seat 28 and the right translation seat 29 from getting too close together. Moreover, relative to the plug 5, the left translation seat 28 and the right translation seat 29 are symmetrically far apart, which does not affect the removal of the photovoltaic inductor, so as to meet the installation and commissioning requirements.

[0082] In some specific embodiments of the present invention, the diameters of the insert 5 and the rotating ring 6 can be more than 5 mm smaller than the inner diameter of the photovoltaic inductor to facilitate assembly. At the same time, there can be a sufficient gap between the insert 5 and the photovoltaic inductor to meet the rotation requirements of the photovoltaic inductor and reduce contact and friction.

[0083] In some specific embodiments of the present invention, a support ring can be provided at the bottom of the insertion rod 5. The support ring can rotate to reduce friction on the photovoltaic inductor end face.

[0084] In some specific embodiments of the present invention, the insert rod 5 can be set horizontally, while the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 can be set vertically to reduce end face contact wear.

[0085] In some specific embodiments of the present invention, the synchronization mechanism 27 may include a fixed base 35, a first channel 36 is provided on the top of the fixed base 35, the first channel 36 accommodates the passage of the first conveyor chain 4, and a first track 37 is provided on the bottom of the fixed base 35. One end of the first track 37 is slidably connected to the left translation seat 28, and the other end of the first track 37 is slidably connected to the right translation seat 29.

[0086] It is easy to understand that by setting the fixed seat 35, this embodiment can meet the installation and arrangement requirements of the translation seat, the first track 37, and the first conveyor chain 4, simplifying the structure, reducing costs, and making the layout more compact.

[0087] In some specific embodiments of the present invention, the bottom of the fixed base 35 may be provided with a pointed cone 38, which is inserted between the left swing arm 33 and the right swing arm 34 to separate the left swing arm 33 and the right swing arm 34. A return spring is connected between the left swing arm 33 and the right swing arm 34 to bring the left swing arm 33 and the right swing arm 34 closer together. The left swing arm 33 is provided with a left roller 39 that rolls along the pointed cone 38, and the right swing arm 34 is provided with a right roller 40 that rolls along the pointed cone 38. The left translation base 28 is provided with a left groove 41 for accommodating the left roller 39, and the right translation base 29 is provided with a right groove 42 for accommodating the right roller 40.

[0088] It is easy to understand that by setting the pointed cone 38 and the return spring, this embodiment can make the left swing arm 33 and the right swing arm 34 move closer and further away from each other in an orderly manner, avoiding the swing arms from swinging randomly due to separation from the translation seat, improving equipment reliability and reducing the occurrence of failures.

[0089] Meanwhile, the pointed cone 38 is formed at the bottom of the fixed base 35, which reduces the difficulty of manufacturing and placement, and reduces manufacturing costs.

[0090] The groove is used to accommodate the roller, which can adapt to the swing arm's swing requirements. It can limit the end of the swing arm to prevent it from falling off, and it can also withstand the force of the swing arm, thus having good adaptability.

[0091] In some specific embodiments of the present invention, the pointed cone 38 and the first track 37 can be staggered in the horizontal direction for reasonable arrangement and full utilization of existing space.

[0092] In some specific embodiments of the present invention, the pointed cone portion 38 may have two arc-shaped sides for contacting the roller, thereby allowing the roller to smoothly enter and exit the groove, reducing noise and abnormal sounds.

[0093] After the external shaping is completed, the photovoltaic inductor can be transferred to the internal shaping module 9 by a robotic arm or manual operation for internal shaping.

[0094] In some specific embodiments of the present invention, internal shaping can be performed first and then external shaping. However, the change of the shaping reference needs to be considered. If external shaping is not performed first, the outer surface of the photovoltaic inductor cannot be used as a force reference. Internal shaping requires the use of internal support shaping, as mentioned in the prior art. The structure is difficult to arrange, the strength is limited, and it is difficult to achieve continuous full-circumference shaping of the inner surface, which is not conducive to shaping efficiency.

[0095] Among them, reference Figure 4 and Figure 5 For the inner shaping module 9, the inner shaping module 9 includes a second conveying device 10 and an inner shaping device 11. The second conveying device 10 includes a second conveying chain 12 and a sleeve 13 disposed on the second conveying chain 12. The photovoltaic inductor is fitted inside the sleeve 13. The inner shaping device 11 includes a turntable 14 and an insert rod 15 eccentrically disposed on the turntable 14. When the turntable 14 and the sleeve 13 are concentric, the insert rod 15 can extend into the sleeve 13. The insert rod 15 is provided with an inner shaping part 16, which is used to abut against the radial inner surface of the photovoltaic inductor.

[0096] In some specific embodiments of the present invention, the turntable 14 and the sleeve 13 can be made concentric after the insertion rod 15 enters the sleeve 13, so as to reduce the difficulty of the inner shaping part 16 entering and avoid the coil from being scratched along the axis of the photovoltaic inductor.

[0097] In some specific embodiments of the present invention, the turntable 14 can be driven by a motor to resist the rotational resistance during shaping.

[0098] In some specific embodiments of the present invention, the insertion rod 15 can be connected to a cylinder to realize the extension and retraction of the insertion rod 15.

[0099] In some specific embodiments of the present invention, the inner shaping portion 16 may have a guiding portion, thereby reducing damage to the coil.

[0100] In some specific embodiments of the present invention, the inner shaping part 16 may include a flange ring 46 fitted onto the plug rod 15, an end cap 47 connecting the end of the plug rod 15, and a plurality of rollers 48 connecting the flange ring 46 and the end cap 47, wherein the rollers 48 are used to abut against the radial inner surface of the photovoltaic inductor.

[0101] It is easy to understand that, by setting the roller 48, the full circumferential shaping of the radial inner surface of the photovoltaic inductor can be achieved through the rotation of the turntable 14 and the revolution of the roller 48.

[0102] The flange ring 46 and the end cap 47 can support both ends of the roller 48, so that the balls can fully contact the coil to shape the coil at various positions and improve the integrity of the shaping.

[0103] In some specific embodiments of the present invention, the roller 48 may be provided with a plurality of annular protrusions 49, and the plurality of annular protrusions 49 are arranged along the axis of the roller 48.

[0104] It is easy to understand that by setting the annular protrusion 49 in this embodiment, the annular protrusion 49 also contacts the coil first, generating multiple bending shapes. That is, the shaping is to shape a long arc into multiple short arcs, reducing the extension of the coil to both ends of the photovoltaic inductor and avoiding mutual interference between the inner shaping and the end face shaping.

[0105] In some specific embodiments of the present invention, the inner shaping part 16 may include a rolling sleeve fitted onto the insert rod 15 and a limiting retaining ring snapped onto the insert rod 15, the limiting retaining ring being used to limit the rotation of the rolling sleeve onto the insert rod 15.

[0106] It is easy to understand that by setting the rolling sleeve and the limiting ring, the structure of the inner shaping part 16 can be simplified, the installation difficulty can be reduced, and the manufacturing and use costs can be reduced.

[0107] In some specific embodiments of the present invention, the sleeve 13 may be provided with a plurality of elastic inner liners 50 for abutting and positioning the photovoltaic inductor.

[0108] It is easy to understand that by setting the elastic inner liner 50, the photovoltaic inductor can be positioned, reducing the displacement deviation of the photovoltaic inductor in the axial direction. At the same time, it avoids the inner surface of the sleeve 13 from making hard contact with the photovoltaic inductor, reducing the risk of damage to the radial outer surface of the photovoltaic inductor.

[0109] After the internal shaping is completed, the photovoltaic inductor can be transferred to the end-face shaping module 17 by a robotic arm or manual operation for end-face shaping.

[0110] Since the coil deforms less at the end face of the photovoltaic inductor and the shaping amount is low, it is easy to deform again under stress. However, end face shaping after completing the external and internal shaping can avoid the end face of the photovoltaic inductor from deforming again during the external and internal shaping, thus reducing rework and repeated operations.

[0111] Among them, reference Figure 6 and Figure 7For the end face shaping module 17, the end face shaping module 17 includes a third conveying device 18 and an end face shaping device 19. The third conveying device 18 includes a material transfer seat 20 and a material placement rack 21 disposed on the material transfer seat 20. The material placement rack 21 is provided with multiple material placement cavities 22, which are arranged in multiple rows and columns. The material placement cavities 22 are used to place and position the photovoltaic inductor. The photovoltaic inductor is in an upright state. The end face shaping device 19 includes an upper shaping frame 23 and a lower shaping frame 24. The lower shaping frame 24 rises to support the material placement rack 21, and the upper shaping frame 23 descends and presses the end face of the photovoltaic inductor.

[0112] In summary, this embodiment, by setting the outer shaping module 1, the inner shaping module 9, and the end face shaping module 17, can achieve the shaping treatment of the radial outer surface, radial inner surface, and end face of the photovoltaic inductor, so that the shape of the photovoltaic inductor is close to the design requirements. On the one hand, it avoids the impact of shape differences on assembly and improves assembly convenience. On the other hand, the coil arrangement of the photovoltaic inductor is closer to the design state. Therefore, the performance of the photovoltaic inductor is closer to the theoretical effect, which can meet the high-quality requirements of customers.

[0113] In this embodiment, by setting a first conveyor chain 4 with insert rods 5, the photovoltaic inductor can be fitted onto the outside of the insert rods 5. Through the continuous conveying of the first conveyor chain 4, the photovoltaic inductor can be automatically supplied, which helps to realize the automated and continuous external shaping.

[0114] In this embodiment, by giving the insert 5 a rotating ring 6, the rotating ring 6 can rotate synchronously when the photovoltaic inductor rotates, reducing relative friction and wear, which is beneficial for protecting the coil. At the same time, it also facilitates full-circumference shaping of the radial outer surface of the photovoltaic inductor, improving the integrity of the shaping and reducing the blind zone of the outer shaping.

[0115] In this embodiment, by setting a forward pressing conveyor belt 7 and a reverse pressing conveyor belt 8, when the insert 5 passes between the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8, the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 work together to twist and shape the radial outer surface of the photovoltaic inductor, so that the photovoltaic inductor not only moves with the insert 5 and the first conveyor chain 4, but also rotates at the same time. This can achieve uniform shaping of the radial outer surface of the photovoltaic inductor around the entire circumference, which can not only avoid shaping omissions, but also help improve the shaping quality.

[0116] At the same time, it also enables the first conveyor chain 4 to transport materials over long distances, reducing or even eliminating pauses, which helps improve shaping efficiency.

[0117] In this embodiment, by setting up a second conveyor chain 12 and a sleeve 13, the photovoltaic inductor can be fitted inside the sleeve 13. Through the continuous conveying of the second conveyor chain 12, the photovoltaic inductor can be automatically supplied, which helps to realize the automated and continuous external shaping.

[0118] The bushing 13 can improve the positional accuracy by limiting the outer side of the photovoltaic inductor, and facilitate the automated shaping of the radial inner surface of the photovoltaic inductor, reducing the difficulty of shaping.

[0119] In this embodiment, by setting a turntable 14 and an insert 15 eccentrically set on the turntable 14, when the turntable 14 is concentric with the sleeve 13, the insert 15 can extend into the sleeve 13. Then, the turntable 14 is rotated, and the inner shaping part 16 of the insert 15 abuts against different positions of the radial inner surface of the photovoltaic inductor, thereby achieving full circumferential shaping of the inner surface, improving the integrity of the shaping, and reducing the blind area of ​​the inner shaping.

[0120] Meanwhile, the bushing 13 can uniformly limit the outer side of the photovoltaic inductor to withstand the internal shaping force and prevent the turntable 14 from spinning idly.

[0121] In this embodiment, by setting up a material transfer seat 20 and a material placement rack 21, the material placement rack 21 is provided with multiple material placement chambers 22, which are arranged in multiple rows and columns. Therefore, it is convenient to place multiple photovoltaic inductors on the material placement rack 21. Then, the material transfer seat 20 moves the material placement rack 21 to the end face shaping device 19. The end face shaping of multiple photovoltaic inductors can be completed by pressing once, which improves the end face shaping efficiency. At the same time, it also keeps the loading and unloading operations or work away from the end face shaping device 19, which improves the safety of end face shaping.

[0122] At the same time, the end face shaping of multiple photovoltaic inductors can be completed in one press, which also helps to distribute the end face shaping force evenly. That is, a large force is divided into multiple smaller forces, which can not only meet the end face shaping needs, but also reduce the difficulty of equipment manufacturing and reduce manufacturing costs.

[0123] In this embodiment, by setting an upper shaping frame 23 and a lower shaping frame 24, the lower shaping frame 24 rises to support the material placement frame 21, and the upper shaping frame 23 descends to press the end face of the photovoltaic inductor. Therefore, on the one hand, the squeezing between the material placement frame 21 and the material transfer seat 20 is reduced, the force on the guide rail is reduced, and the equipment is made more durable. At the same time, the lower shaping frame 24 and the upper shaping frame 23 can press the end face of the photovoltaic inductor with a set pressure, reducing the risk of damage to the photovoltaic inductor.

[0124] In some specific embodiments of the present invention, the material transfer seat 20 can be driven to move by a motor and a screw, which facilitates precise control of the moving position.

[0125] In some specific embodiments of the present invention, the upper shaping frame 23 and the lower shaping frame 24 can be driven by hydraulic power to precisely control the pressing pressure.

[0126] In some specific embodiments of the present invention, the material rack 21 can be placed quickly and accurately on the material transfer seat 20 by means of the cooperation of the positioning pin and the positioning hole.

[0127] In some specific embodiments of the present invention, the lower shaping frame 24 may include a lower pressure plate 51, a positioning spring pin 52 disposed on the lower pressure plate 51, and an elastic pressure ring 53 fitted on the outside of the positioning spring pin 52. The positioning spring pin is used to insert into the inner side of the photovoltaic inductor, and the elastic pressure ring 53 is used to abut against the end face of the photovoltaic inductor for shaping.

[0128] The elastic pressure ring 53 can be pressed against the lower pressure plate 51 by a spring, and the elastic pressure ring can be slidably connected to the positioning spring pin 52 by a sliding groove and a locking screw, so as to facilitate relative movement to meet the shaping needs.

[0129] The positioning spring pin 52 can be elastically set at its end, such as by using elastic material, to achieve elastic contact with the photovoltaic inductor, which not only meets the positioning requirements but also reduces the risk of impact damage.

[0130] Among them, reference Figure 8 For the conversion module, the conversion module is mainly used to transfer the photovoltaic inductor from the outer shaping module 1 to the inner shaping module 9.

[0131] Specifically, for cases where both the first conveyor chain 4 and the second conveyor chain 12 involve translational conveying and flipping return, a conversion device 43 is provided between the first conveyor device 2 and the second conveyor device 10. The conversion device 43 includes an inclined conveyor belt 44, which is equipped with multiple push rods 45. Near the first conveyor chain 4, the push rods 45 abut against one end of the photovoltaic inductor to separate the photovoltaic inductor from the insertion rod 5. Near the second conveyor chain 12, the push rods 45 push the photovoltaic inductor into the sleeve 13.

[0132] Meanwhile, the feeding rod 45 can separate adjacent photovoltaic inductors, enabling the photovoltaic inductors to be fed one by one.

[0133] The inclined conveyor belt 44 is inclined to accommodate the height differences between shaping modules and is easy to use.

[0134] Reference Figure 9 and Figure 10 The present invention also aims to provide a method for producing photovoltaic inductors, applicable to any one of the photovoltaic inductor production equipment;

[0135] Production methods include:

[0136] In the external shaping step S1, the photovoltaic inductor is mounted on the plug 5. The first conveyor chain 4 drives the plug 5 and the photovoltaic inductor to move between the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8. The forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 squeeze the radial outer surface of the photovoltaic inductor. The forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 move in opposite directions, causing the photovoltaic inductor to rotate simultaneously until the photovoltaic inductor moves out from between the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8, thus completing the external shaping.

[0137] In the internal shaping step S2, the photovoltaic inductor is inserted into the sleeve 13. The second conveyor chain 12 conveys the sleeve 13 and the photovoltaic inductor to the turntable 14. When the turntable 14 is concentric with the sleeve 13, the insertion rod 15 extends into the sleeve 13. Then, the turntable 14 rotates, and the internal shaping part 16 abuts against different parts of the radial inner surface of the photovoltaic inductor to complete the internal shaping. Then, the insertion rod 15 retracts, and the second conveyor chain 12 continues to convey the sleeve 13 and the photovoltaic inductor.

[0138] In the end-face shaping step S3, the photovoltaic inductor is installed into the placement cavity 22 of the placement rack 21. The material transfer seat 20 moves the placement rack 21 between the upper shaping rack 23 and the lower shaping rack 24. The lower shaping rack 24 rises to support the placement rack 21, and the upper shaping rack 23 descends and presses the end face of the photovoltaic inductor to complete the end-face shaping. Then, the upper shaping rack 23 and the lower shaping rack 24 are reset, and the material transfer seat 20 moves the placement rack 21 to the unloading position.

[0139] In some specific embodiments of the present invention, the external shaping device 3 may include a synchronization mechanism 27. The synchronization mechanism 27 includes a left translation seat 28, a right translation seat 29, and a proximity spring 30 that drives the left translation seat 28 and the right translation seat 29 to move closer to each other. The synchronization mechanism 27 also includes a lifting separation seat 31 and an electric cylinder 32 that drives the lifting separation seat 31 to move up and down. The lifting separation seat 31 is hinged with a left swing arm 33 and a right swing arm 34. The free end of the left swing arm 33 abuts against the left translation seat 28, and the free end of the right swing arm 34 abuts against the right translation seat 29, so that the left translation seat 28 and the right translation seat 29 are separated from each other. The synchronization mechanism 27 includes a fixed seat 35. The top of the fixed seat 35 is provided with a first channel 36, through which the first conveyor chain 4 passes. The bottom of the fixed seat 35 is provided with a first track 37, one end of which is slidably connected to the left translation seat 28, and the other end of which is slidably connected to the right translation seat 29. The bottom of the fixed seat 35 is provided with a pointed cone 38, which is inserted between the left swing arm 33 and the right swing arm 34 to separate the left swing arm 33 and the right swing arm 34. A return spring is connected between the left swing arm 33 and the right swing arm 34 to bring the left swing arm 33 and the right swing arm 34 closer together. The left swing arm 33 is provided with a left roller 39 that rolls along the pointed cone 38, and the right swing arm 34 is provided with a right roller 40 that rolls along the pointed cone 38. The left translation seat 28 is provided with a left groove 41 for accommodating the left roller 39, and the right translation seat 29 is provided with a right groove 42 for accommodating the right roller 40.

[0140] Therefore, in the external shaping step S1, when the photovoltaic inductor moves between the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8, the electric cylinder 32 drives the lifting separation seat 31 to descend, the left roller 39 disengages from the left groove 41, the right roller 40 disengages from the right groove 42, the reset spring causes the left swing arm 33 and the right swing arm 34 to move closer to each other, the left roller 39 and the right roller 40 move along the cone 38 and move closer to each other, the approach spring 30 drives the left translation seat 28 and the right translation seat 29 to move closer to each other along the first track 37, and the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 move closer to each other to squeeze the photovoltaic inductor;

[0141] When the photovoltaic inductor moves out from between the forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8, the electric cylinder 32 drives the lifting separation seat 31 to rise. The left roller 39 and the right roller 40 move along the pointed cone 38 and move away from each other. The left swing arm 33 and the right swing arm 34 move away from each other. The left roller 39 enters the left groove 41 and pushes the left translation seat 28. The right roller 40 enters the right groove 42 and pushes the right translation seat 29. The left translation seat 28 and the right translation seat 29 move away from each other along the first track 37. The forward pressing conveyor belt 7 and the reverse pressing conveyor belt 8 move away from each other to release the compression.

The synchronization mechanism (27) also includes a lifting separation seat (31) and an electric cylinder (32) that drives the lifting separation seat (31) to lift. The lifting separation seat (31) is hinged with a left swing arm (33) and a right swing arm (34). The free end of the left swing arm (33) abuts against the left translation seat (28), and the free end of the right swing arm (34) abuts against the right translation seat (29) so that the left translation seat (28) and the right translation seat (29) separate from each other. The synchronization mechanism (27) includes a fixed seat (35), a first channel (36) is provided on the top of the fixed seat (35), the first channel (36) accommodates the passage of the first conveyor chain (4), and a first track (37) is provided on the bottom of the fixed seat (35). One end of the first track (37) is slidably connected to the left translation seat (28), and the other end of the first track (37) is slidably connected to the right translation seat (29). The bottom of the fixed base (35) is provided with a pointed cone (38), which is inserted between the left swing arm (33) and the right swing arm (34) to separate the left swing arm (33) and the right swing arm (34) from each other. A return spring (54) is connected between the left swing arm (33) and the right swing arm (34). The return spring (54) is used to bring the left swing arm (33) and the right swing arm (34) closer together. The left swing arm (33) is provided with a left roller (39) that rolls along the pointed cone (38), and the right swing arm (34) is provided with a right roller (40) that rolls along the pointed cone (38). The left translation base (28) is provided with a left groove (41) for accommodating the left roller (39), and the right translation base (29) is provided with a right groove (42) for accommodating the right roller (40). In the external shaping step, when the photovoltaic inductor moves between the forward pressing conveyor belt (7) and the reverse pressing conveyor belt (8), the electric cylinder (32) drives the lifting separation seat (31) to descend, the left roller (39) disengages from the left groove (41), the right roller (40) disengages from the right groove (42), the reset spring (54) causes the left swing arm (33) and the right swing arm (34) to move closer to each other, the left roller (39) and the right roller (40) move along the cone (38) and move closer to each other, the approach spring (30) drives the left translation seat (28) and the right translation seat (29) to move closer to each other along the first track (37), and the forward pressing conveyor belt (7) and the reverse pressing conveyor belt (8) move closer to each other to squeeze the photovoltaic inductor; When the photovoltaic inductor moves out from between the forward pressing conveyor belt (7) and the reverse pressing conveyor belt (8), the electric cylinder (32) drives the lifting separation seat (31) to rise, the left roller (39) and the right roller (40) move along the cone (38) and move away from each other, the left swing arm (33) and the right swing arm (34) move away from each other, the left roller (39) enters the left groove (41) and pushes the left translation seat (28), the right roller (40) enters the right groove (42) and pushes the right translation seat (29), the left translation seat (28) and the right translation seat (29) move away from each other along the first track (37), and the forward pressing conveyor belt (7) and the reverse pressing conveyor belt (8) move away from each other to release the squeezing.
