Description

Technical Field

[0001] This utility model relates to the field of inductor production technology, and in particular to an inductor powder molding equipment and an inductor production line. Background Technology

[0002] In the production process of integrally molded inductors, inductor powder coating refers to the process of uniformly covering the surface and surrounding area of ​​the coil winding with magnetic powder. The purpose is to integrate the magnetic powder with the coil winding into a single unit through subsequent die casting, thereby endowing the inductor with excellent magnetic properties, electrical performance, and structural strength. This process is a key step in achieving miniaturization and high performance of inductors, directly affecting the core indicators of the final product, such as permeability, loss, and temperature resistance.

[0003] In existing technologies, powder coating of inductors with multiple coil windings typically employs a multi-row mold synchronous operation method. For example, multiple coil windings are arranged in an array on a base plate, and multiple rows of molds with powder spray nozzles are set at the positions of the coil windings. A drive mechanism moves the base plate or molds to align the powder spray nozzles of the molds with the coil windings, and then magnetic powder is sprayed onto multiple coil windings simultaneously. Some equipment also incorporates a pressurizing mechanism to pre-press the powder after spraying, preparing it for subsequent die casting.

[0004] However, when the number of mold rows increases, it is difficult to keep the powder spraying pressure and powder flow rate of each row of molds consistent. This can easily lead to situations where the powder coating on some coil winding surfaces is too thick and others is too thin, resulting in uneven powder coverage. Consequently, after die casting, problems such as inconsistent product density and fluctuations in magnetic properties occur, affecting the molding effect. Utility Model Content

[0005] The main purpose of this utility model is to provide an inductor powder molding equipment and an inductor production line, which aims to solve the problem of uneven coating caused by multiple rows of molds spraying a large amount of powder at the same time in the prior art.

[0012] In one embodiment, the powder spraying device further includes a pressurizing mechanism, a pressure plate, and a press head. The pressurizing mechanism includes a lifting seat and a driving member. The lifting seat is disposed on the frame, and the driving member is used to drive the lifting seat to move along the third direction.

The press head includes a plurality of pressurizing punches disposed on the side of the pressure plate facing the support seat, and the plurality of pressurizing punches are spaced apart along the second direction.

[0013] The powder spraying section and the pressure head are spaced apart in the first direction. The powder spraying section includes a plurality of powder spraying pipes disposed on the side of the pressure plate facing the support seat. The plurality of powder spraying pipes are spaced apart along the second direction. The powder spraying pipes have powder spraying nozzles on the side facing the support seat.

[0014] In one embodiment, the pressurizing punch includes a punch body and a connecting section, the connecting section being fixed to the pressure plate, and the punch body being detachably connected to the end of the connecting section away from the pressure plate;

[0015] The powder spray nozzle is located on the side of the punch body away from the connecting section.

[0016] In one embodiment, the punch body is threadedly connected to the connecting section.

[0017] In one embodiment, the inductor powder forming equipment further includes a guiding structure, which includes a guide post and a guide hole. One of the guide post and the guide hole is located on the side of the machine base facing the pressure plate, and the other is located on the side of the pressure plate facing the support seat.

[0018] In one embodiment, the drive mechanism includes:

[0019] A lead screw, which extends along the first direction;

[0020] Nut seat, the nut seat being movably sleeved on the transmission lead screw, the nut seat being fixedly connected to the bearing seat or the frame; and

[0021] A servo motor is connected to the lead screw for transmission.

[0022] In one embodiment, both ends of the transmission lead screw are mounted on the machine base via support seats, and the nut seat is fixedly connected to the bearing seat;

[0023] The inductor powder molding equipment also includes a guide rail, which is disposed on the machine base and extends along the first direction;

[0024] The support seat has a guide groove on the side facing away from the powder spraying device, which slides in conjunction with the guide rail.

[0025] In one embodiment, the bottom wall of the material trough is provided with adsorption holes;

[0030] The inductor powder forming equipment provided by this utility model solves the problem of uneven coating caused by the simultaneous spraying of a large number of powders from multiple rows of molds in the prior art by employing multiple material trough groups spaced apart along a first direction, multiple powder spraying nozzles spaced apart along a second direction on the powder spraying unit, and a drive mechanism that moves the support base or the powder spraying unit along the first direction. Specifically, multiple material trough groups on the support base are spaced apart along the first direction, and multiple material troughs in each material trough group are arranged along the second direction. The number of powder spraying nozzles on the powder spraying unit matches the number of material troughs in a single material trough group and is correspondingly set along the second direction. During operation, the drive mechanism moves the support base or the powder spraying unit along the first direction, so that the powder spraying unit first aligns with the first row of material trough groups, and the powder spraying nozzles only spray the coil windings in that row of material troughs. After completion, it continues to move and sprays the second row of material trough groups, and so on, completing the spraying of all rows of windings in multiple stages. This method of spraying powder in multiple stages, reducing the number of powders sprayed simultaneously each time, avoids the problem of inconsistent powder supply pressure and flow rate of each row of molds when spraying powder on multiple rows of windings at the same time. Furthermore, since each spraying only requires controlling the powder spray nozzle corresponding to one row of material troughs, the pressure and flow regulation of the powder supply system are more precise, improving the output consistency of each powder spray nozzle and enhancing the production quality of the integrally molded inductor.

[0039] This utility model proposes an inductor powder forming equipment 100.

[0040] Please see Figure 1 In one embodiment, the inductor powder molding apparatus 100 proposed by this utility model includes:

[0041] Machine 1;

[0042] The support seat 2 is located on the machine base 1. On the side of the support seat 2 away from the machine base 1, there are multiple material troughs 21 arranged at intervals along the first direction. The material troughs 21 include multiple material troughs 21 arranged at intervals along the second direction. The material troughs 21 are used to place coil windings.

[0043] The powder spraying device 3 includes a frame 31 and a powder spraying section 34 disposed on the frame 31. The frame 31 is disposed on the machine base 1. The powder spraying section 34 is spaced apart from the support base 2 in a third direction and is located on the side of the support base 2 facing away from the machine base 1. The powder spraying section 34 has multiple powder spraying nozzles on the side facing the support base 2, and the multiple powder spraying nozzles are spaced apart along a second direction.

[0044] The drive mechanism is connected to the carrier 2 or the frame 31 and is used to drive the carrier 2 or multiple powder spraying parts 34 to move in the first direction.

[0045] The first direction, the second direction, and the third direction are set perpendicular to each other.

[0046] It should be noted that during operation, the powder spraying unit 34 obtains magnetic powder by connecting to the powder supply system, which provides stable powder conveying pressure and flow rate. The powder spraying unit 34 can be composed of multiple independently arranged spray nozzles, each corresponding to a material trough 21. The outlet of each nozzle forms a powder spraying port. Multiple nozzles are arranged at intervals along the second direction and fixed to the same mounting plate, which is connected to the frame 31. Alternatively, it can be an integrated powder spraying block. The powder spraying block has a one-piece structure with multiple powder spraying ports machined at intervals along the second direction on the side facing the support 2. The powder spraying block has a main channel connecting all the powder spraying ports, which is connected to the powder supply system via a pipeline. The design of multiple independent spray nozzles facilitates individual adjustment of the angle and position of each powder spraying port, making it suitable for adapting to different specifications of coil windings.

[0047] The drive mechanism typically possesses high transmission accuracy and stability, and can be a linear motor drive mechanism. The stator of the linear motor is fixedly mounted along a first direction, and the mover is connected to the support 2 or frame 31. When the linear motor is energized, the mover directly moves linearly on the stator, driving the support 2 or powder spraying section 34 to move. Alternatively, a servo motor combined with a synchronous belt drive mechanism can be used, consisting of a servo motor, synchronous pulleys, and a synchronous belt. The servo motor drives the active synchronous pulley to rotate, which in turn drives the driven synchronous pulley to rotate via the synchronous belt. The driven synchronous pulley cooperates with a lead screw or slide rail positioned along the first direction to convert rotational motion into linear motion. Alternatively, a cylinder drive mechanism can be used, utilizing compressed air as a power source. The piston rod of the cylinder is connected to the support 2 or frame 31. When the cylinder is energized, the piston rod extends and retracts, causing the support 2 or powder spraying section 34 to move along the first direction.

[0048] The inductor powder forming equipment 100 provided by this utility model solves the problem of uneven coating caused by the simultaneous spraying of a large number of powders from multiple rows of molds in the prior art by employing multiple groups of material troughs 21 spaced apart along a first direction, multiple powder spraying nozzles spaced apart along a second direction on the powder spraying part 34, and a driving mechanism that drives the support base 2 or the powder spraying part 34 to move along the first direction. Specifically, the multiple groups of material troughs 21 on the support base 2 are distributed spaced apart along the first direction, and the multiple material troughs 21 in each group of material troughs 21 are arranged along the second direction. The number of powder spraying nozzles of the powder spraying part 34 matches the number of material troughs 21 in a single group of material troughs 21 and is correspondingly arranged along the second direction. During operation, the driving mechanism drives the support base 2 or the powder spraying part 34 to move along the first direction, so that the powder spraying part 34 first aligns with the first group of material troughs 21, and the powder spraying nozzles only spray the coil windings in that group of material troughs 21. After completion, it continues to move and sprays the second group of material troughs 21, and so on, completing the spraying of all rows of windings in multiple times. This method of spraying powder in multiple stages, reducing the amount of powder sprayed simultaneously each time, avoids the problem of inconsistent powder supply pressure and flow rate of each row of molds when spraying powder on multiple rows of windings at the same time. Moreover, since each spray only needs to control the powder spray nozzle corresponding to one row of material troughs 21, the pressure and flow rate adjustment of the powder supply system is more precise, improving the output consistency of each powder spray nozzle and enhancing the production quality of the integrally molded inductor.

[0049] In one embodiment, the powder spraying device 3 further includes a pressurizing mechanism 32, a pressure plate 33, and a pressing head. The pressurizing mechanism 32 includes a lifting seat 321 and a driving member. The lifting seat 321 is disposed on the frame 31, and the driving member is used to drive the lifting seat 321 to move along a third direction. The pressure plate 33 is disposed on the lifting seat 321, and the pressure plate 33 and the bearing seat 2 are spaced apart in a third direction. The pressing head includes a plurality of pressurizing punches 351 disposed on the side of the pressure plate 33 facing the bearing seat 2, and the plurality of pressurizing punches 351 are spaced apart along a second direction.

[0050] The powder spraying section 34 and the pressure head are spaced apart in the first direction. The powder spraying section 34 includes a plurality of powder spraying pipes 341 disposed on the side of the pressure plate 33 facing the support seat 2. The plurality of powder spraying pipes 341 are spaced apart in the second direction. The powder spraying pipes 341 have powder spraying nozzles on the side facing the support seat 2.

[0051] In this embodiment, when the support seat 2 moves the material trough 21 group to below the powder spraying section 34, the driving component drives the lifting seat 321 to descend, so that the powder spraying pipe 341 approaches the material trough 21. The powder spraying pipe 341 sprays powder onto the coil winding through the powder spraying nozzle. After the powder spraying is completed, the support seat 2 or the powder spraying device 3 moves along the first direction, so that the pressure punch 351 of the pressure head is aligned with the powder-sprayed material trough 21 group. The driving component drives the lifting seat 321 to descend again, and the pressure punch 351 pressurizes the powder. Then the lifting seat 321 rises, and the equipment continues to repeat the above powder spraying, moving, and pressurizing process for the next row of material trough 21 groups. Of course, the pressurizing unit 35 and the powder spraying unit 34 can be set up in two adjacent rows of powder spraying units 34. In this way, the powder spraying unit 34 first sprays powder onto the coil windings of the current discharge trough 21 group. At the same time, since the pressurizing unit 35 and the powder spraying unit 34 are set up in two adjacent rows, the pressurizing unit 35 is facing the previous row of trough 21 groups that have been sprayed with powder. While the powder spraying unit 34 is spraying powder, the driving component drives the lifting seat 321 to descend, and the pressurizing punch 351 of the pressurizing unit 35 pressurizes the powder of the previous row. After the powder spraying and pressurizing are completed, the bearing seat 2 continues to move one trough 21 group spacing, the powder spraying unit 34 sprays powder onto the next row of trough 21 groups, and the pressurizing unit 35 pressurizes the current discharge trough 21 group that has just been sprayed with powder, and so on in a cycle.

[0052] Of course, in other embodiments, the powder spraying unit 34 and the pressurizing mechanism 32 may not be integrated into the same device. Instead, they may be arranged sequentially on the frame 31 along the first direction to form independent powder spraying and pressurizing stations. Specifically, the powder spraying unit 34 is installed separately on one side of the frame 31, and the pressurizing mechanism 32 (including the lifting seat 321, the driving component, and the pressure plate 33) is installed on the other side of the frame 31, with space between them for the carrier 2 to move. When the equipment is working, the driving mechanism first drives the carrier 2 to move along the first direction to the powder spraying station, and the powder spraying nozzle of the powder spraying unit 34 completes the spraying of the coil winding in the material tank 21. Subsequently, the driving mechanism continues to drive the carrier 2 to move to the pressurizing station, and the driving component of the pressurizing mechanism 32 drives the lifting seat 321 to descend, so that the pressurizing punch 351 on the pressure plate 33 pressurizes the coil winding that has been sprayed with powder. After completion, the carrier 2 moves to the next position, and the powder spraying and pressurizing operations are repeated in sequence. In this way, the powder spraying unit 34 and the pressurizing mechanism 32 can be designed with parameters independently according to their respective functional requirements. For example, the powder spraying unit 34 can focus on optimizing parameters such as powder spraying pressure and flow rate, while the pressurizing mechanism 32 can adjust the pressure and stroke independently, avoiding mutual constraints between parameters during integrated design. For inductor products with large differences in powder spraying and pressurizing process requirements (such as different powder particle sizes and different pressurization intensity requirements), independent settings can be more flexibly adapted and adjusted, reducing the difficulty of equipment modification. In addition, when a single mechanism fails, it can be shut down for maintenance without affecting the temporary emergency use of the other mechanism, improving the fault tolerance and production continuity of the equipment.

[0053] In one embodiment, the pressurizing punch 351 includes a punch body and a connecting section. The connecting section is fixed to the pressure plate 33, and the punch body and the end of the connecting section away from the pressure plate 33 are detachably connected. The powder spraying nozzle is located on the side of the punch body away from the connecting section.

[0054] It should be noted that detachable connection refers to a connection method that can be loosened by screwing or separated by snap-fit. This requires that both the connecting section and the punch body have powder feeding channels, that is, the powder feeding channel of the punch body is connected to the powder spraying nozzle, and the two ends of the powder feeding channel of the connecting section are connected to the external powder supply system and the powder feeding channel of the punch body, respectively.

[0055] In this embodiment, when it is necessary to adjust the position or size of the powder injection nozzle for coil windings of different sizes, it is not necessary to replace the entire pressure punch 351. Simply remove the punch body from the connecting section, replace it with a punch body that has a powder injection nozzle of the corresponding specification, and then reconnect and fix the new punch body to the connecting section. During routine maintenance, if the powder injection nozzle becomes clogged or worn, only the punch body needs to be replaced; the connecting section can continue to be used. The detachable connection design significantly reduces the cost of replacing parts, avoids replacing the entire unit due to partial damage to the punch, and saves on equipment maintenance costs. By quickly replacing different punch bodies, it can flexibly adapt to the powder injection and pressure requirements of different coil windings, improving the equipment's compatibility with multiple product specifications.

[0056] In one embodiment, the punch body is threadedly connected to the connecting section.

[0057] In this embodiment, the end of the punch body near the connecting section has an external thread, and the end of the connecting section away from the pressure plate 33 has an internal thread that matches the external thread. During installation, the punch body is screwed into the connecting section and tightened to secure it. During disassembly, the punch body is rotated in the opposite direction to separate it from the connecting section. This threaded connection method ensures a tight fit between the punch body and the connecting section, effectively preventing gaps at the powder feeding channel joint that could lead to powder leakage. Furthermore, disassembly and assembly can be completed without complex tools, simply by rotation, significantly improving the efficiency of replacing the punch body or cleaning the powder feeding channel.

[0058] In one embodiment, the inductor powder forming equipment 100 further includes a guide structure 4, which includes a guide post 41 and a guide hole 42. One of the guide post 41 and the guide hole 42 is located on the side of the machine base 1 facing the pressure plate 33, and the other is located on the side of the pressure plate 33 facing the support seat 2.

[0059] In this embodiment, when the driving component of the pressurizing mechanism 32 drives the lifting seat 321 to lower the pressure plate 33 along the third direction, the guide post 41 gradually inserts into the corresponding guide hole 42. Under the combined action of both, the descent trajectory of the pressure plate 33 is restricted and guided, ensuring that the pressure plate 33 always moves precisely along the third direction, allowing the pressurizing punch 351 to accurately align with the coil winding in the material groove 21. After pressurization is completed, when the pressure plate 33 rises, the guide post 41 is pulled out from the guide hole 42, maintaining a stable trajectory under the action of the guide structure 4. Thus, the guide structure 4 ensures the relative positional accuracy of the pressure plate 33 and the support seat 2 in the third direction, preventing misalignment between the pressurizing punch 351 and the material groove 21 due to offset, ensuring that the pressurizing pressure is applied evenly to the powder, and improving the density consistency of the molded product.

[0060] In one embodiment, the drive mechanism includes:

[0061] A lead screw, which extends along a first direction;

[0062] Nut seat, movably sleeved on the transmission lead screw, nut seat fixedly connected to bearing seat 2 or frame 31; and

[0063] Servo motor, the servo motor is connected to the transmission lead screw.

[0064] In this embodiment, when it is necessary to move the support 2 or the powder spraying unit 34 along the first direction, the servo motor starts and drives the transmission screw to rotate. Since the nut seat and the transmission screw are threadedly engaged, the rotation of the transmission screw is converted into the linear motion of the nut seat, thereby driving the support 2 or the frame 31 (and the powder spraying unit 34) fixedly connected to the nut seat to move precisely along the first direction. The servo motor can precisely control the rotation angle and speed, thereby precisely controlling the moving distance and speed of the support 2 or the powder spraying unit 34, and achieving precise alignment of the powder spraying unit 34 with each of the discharge troughs 21.

[0065] In one embodiment, the two ends of the transmission screw are mounted on the machine base 1 via support seats, and the nut seat is fixedly connected to the bearing seat 2; the inductive powder forming equipment 100 also includes a guide slide rail 5, which is mounted on the machine base 1 and extends along the first direction; the bearing seat 2 has a guide groove on the side facing away from the powder spraying device 3 that slides in cooperation with the guide slide rail 5.

[0066] In this embodiment, when the servo motor drives the transmission screw to rotate, the transmission screw maintains stable rotation under the support of the support seat. The nut seat drives the bearing seat 2 to move axially along the transmission screw. At the same time, the guide groove of the bearing seat 2 slides in cooperation with the guide rail 5 of the machine base 1, restricting and guiding the movement trajectory of the bearing seat 2. Throughout the movement process, the support seat ensures that the transmission screw does not wobble radially, and the cooperation between the guide rail 5 and the guide groove further constrains the bearing seat 2, making it move smoothly only in the first direction, avoiding lateral deviation or vertical swaying.

[0067] In one embodiment, the bottom wall of the material tank 21 is provided with adsorption holes;

[0068] The interior of the support 2 has an adsorption channel that connects multiple adsorption holes; the outer wall of the support 2 has a suction hole that connects the adsorption channel.

[0069] The inductor powder forming equipment 100 also includes a vacuum adsorption device, the suction pipe of which is connected to the suction hole.

[0070] In this embodiment, after the coil winding is placed into the material tank 21, the vacuum adsorption device is activated. Air is drawn into the adsorption channel of the support seat 2 through the suction pipe and suction hole, creating a negative pressure within the adsorption channel. This negative pressure acts on the bottom of the coil winding through the adsorption hole, firmly adsorbing the coil winding onto the bottom wall of the material tank 21. During the movement of the support seat 2, the powder spraying by the powder spraying section 34, and the pressurizing process by the pressurizing mechanism 32, the vacuum adsorption device continues to operate, maintaining the adsorption force on the coil winding. Vacuum adsorption can firmly fix the coil winding, preventing displacement or shaking during various processes. It ensures that the powder accurately covers the coil winding during powder spraying and that the pressure is evenly applied to the junction of the powder and the coil winding during pressurization, improving product molding quality. Simultaneously, it eliminates the need for additional mechanical clamping structures, simplifying the design of the material tank 21 and preventing physical damage to the coil winding.

[0071] In one embodiment, the inductor powder forming equipment 100 further includes a vision inspection device disposed on the frame 31. The vision inspection device includes an industrial camera and a light source. The lens of the industrial camera faces the support 2, and the light source is used to illuminate the coil winding in the material tank 21.

[0072] In this embodiment, when the support 2 moves the coil winding in the material trough 21 to below the vision inspection device, the light source is activated to illuminate the coil winding, and the industrial camera captures an image of the coil winding in the material trough 21, obtaining its position and orientation. After the image data is transmitted to the equipment control system, the system analyzes the image to determine whether there are any abnormalities such as offset or tilt in the coil winding. If an abnormality is detected, the system can control the equipment to stop and issue an alarm so that the operator can make timely adjustments; if normal, the subsequent powder spraying or pressurizing process continues.

[0073] This utility model also provides an inductor production line, including an inductor powder forming equipment 100. The specific structure of the inductor powder forming equipment 100 is as described in the above embodiments. Since the inductor production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
