Description

Technical Field

[0001] This utility model relates to the field of magnetic rod inductor processing technology, and in particular to a magnetic rod feeding mechanism. Background Technology

[0002] Magnetic rod inductors, consisting of a magnetic rod and a coil, are common electronic components widely used in fields such as new energy. Traditionally, the magnetic rod and coil are assembled manually, which is labor-intensive, inefficient, and produces inconsistent quality. Therefore, the industry is gradually replacing manual assembly with mechanized equipment, which has improved efficiency and assembly quality to some extent. The assembly of magnetic rod inductors involves multiple processes, including loading the magnetic rod, applying adhesive, and inserting the rod. Even with separate, isolated mechanized equipment for each process, efficiency remains low and cannot meet the increasingly demanding market requirements. Under these circumstances, assembly line equipment is gradually replacing multiple isolated mechanical devices.

[0003] For assembly line equipment, magnetic rods are typically fed continuously via a vibratory feeder. During assembly, the magnetic rods need to be positioned first, and then accurately inserted into the coils. This process usually requires rotating the magnetic rods to improve smoothness. Therefore, using a mechanism that can simultaneously feed and rotate the magnetic rods can simplify the layout of the assembly line equipment, reduce space occupation and equipment operating costs, and improve work efficiency while meeting the corresponding process requirements.

Detailed Implementation

[0016] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figures 1-5 As shown, an embodiment of this utility model provides a magnetic rod feeding mechanism, including a magnetic rod dispensing fixture and a magnetic rod positioning fixture. The magnetic rod dispensing fixture is used to dispense the magnetic rods 1 continuously fed by the vibratory feeder, ensuring that different positioning positions of the magnetic rod positioning fixture all have magnetic rods 1 in place. This allows for the simultaneous assembly of multiple magnetic rods 1 with coils, significantly improving work efficiency compared to assembling a single magnetic rod 1 with a coil sequentially. In addition to positioning the magnetic rods 1, the magnetic rod positioning fixture can also control the rotation of the magnetic rods 1 to insert them into the corresponding coils.

[0020] In this embodiment, the magnetic rod dispensing fixture includes a dispensing base 2, multiple dispensing blocks 3 disposed on the dispensing base 2, and a first top-feeding part. The dispensing base 2 is fixedly installed, for example, by means of a bracket fixedly connected to a workbench. Multiple loading slots 4 are formed on the upper surface of the dispensing base 2, and the shapes of the loading slots 4 match those of the magnetic rods 1, allowing for the loading of a single magnetic rod 1. The dispensing blocks 3 are positioned directly above the loading slots 4 and are fixedly installed to the dispensing base 2. A guide channel 5 is provided inside each dispensing block 3, extending through both the top and bottom of the dispensing block 3. At the bottom of the dispensing block 3, the guide channel 5 communicates with the loading slots 4, allowing the magnetic rods 1 in the guide channel 5 to fall directly into the loading slots 4 under gravity. A material pipe 6 is also provided at the top of the guide channel 5, and the material pipe 6 is connected to the vibratory feeder via a conveying pipe, enabling the magnetic rods 1 in the vibratory feeder to be continuously conveyed to the material pipe 6. The end of the feed tube 6 has a notch that is aligned with the guide channel. Therefore, the magnetic rod 1 that is fed to the end of the feed tube 6 can automatically fall into the guide channel 5 and be temporarily stored in the guide channel 5.

[0021] Understandably, since the magnetic rod 1 is continuously conveyed by a vibratory feeder, the guide channel 5 can be completely filled with the magnetic rod 1, and the corresponding loading slot 4 is also filled with magnetic rod 1. When the magnetic rod 1 in the loading slot 4 moves to the magnetic rod positioning fixture under the action of the first top material part, the adjacent magnetic rod 1 in the guide channel 5 will be replenished into the loading slot 4 under the action of gravity. As a preferred embodiment, the extension direction of the guide channel 5 in this embodiment is set to be wavy to make the best use of the internal space of the material distribution block 3, and also to a certain extent avoid the magnetic rod 1 falling vertically.

[0022] At the same time, such as Figure 2 , Figure 3 As shown, the first ejector section includes a first ejector rod 7, a first ejector seat 8, and a first drive module 9. The first ejector rod 7 and the loading groove 4 are correspondingly and aligned. The first end of the first ejector rod 7 is inserted into the loading groove 4 for ejection, and the second end of the first ejector rod 7 is fixedly connected to the first ejector seat 8. The first ejector seat 8 is connected to the first drive module 9, which is arranged on the distribution seat 2 along a first direction to drive the first ejector seat 8 to move along the first direction. Obviously, the first direction is the extension direction of the loading groove 4. In this embodiment, the first ejector section is located on one side of the loading groove 4 along the first direction, and the magnetic rod positioning clamp is located on the other side of the loading groove 4 along the first direction to facilitate the ejection action of the first ejector section. It should be noted that a through hole is also provided at the corresponding position of the distribution seat 2 for the first ejector rod 7 to pass through the loading groove 4.

[0023] At the same time, such as Figure 4 , Figure 5As shown, the magnetic rod positioning fixture includes a fixture base 10, a magnetic rod chuck 11, a magnetic rod clamping block 12, a second drive module 13, and a second ejector. The magnetic rod chuck 11 is configured to correspond one-to-one with the loading slot 4, allowing it to grip the corresponding magnetic rod 1 via its first end. The second end (closer position) of the magnetic rod chuck 11 is connected to the fixture base 10. The magnetic rod clamping block 12 is located at the first end of the magnetic rod chuck 11, assisting the magnetic rod chuck 11 in gripping and positioning the magnetic rod 1. The fixture base 10 is connected to the second drive module 13, which has degrees of freedom of movement along a first direction and a second direction. Therefore, the first end of the magnetic rod chuck 11 can be close to the loading slot 4, allowing the magnetic rod 1 in the loading slot 4 to be inserted into and clamped by the first end of the magnetic rod chuck 11. Subsequently, the magnetic rod chuck 11 moves in the opposite direction along the first direction, completing the loading of the magnetic rod 1. It is then transferred along the second direction to other process positions on the assembly line equipment.

[0024] It should be noted that when the magnetic rod chuck 11 clamps the magnetic rod 1 into position, a portion of the magnetic rod 1 remains outside the first end of the magnetic rod chuck 11. This is to facilitate the adhesive application process. As shown in the figure, a through hole 14 is provided at the center of the first end of the magnetic rod chuck 11. Multiple clamping grooves are spaced around the through hole 14. Magnetic rod clamping blocks 12 are disposed within the clamping grooves, with their first end (inner end) inserted into the through hole 14. The second end of the magnetic rod clamping block 12 contacts the elastic ring 15 (similar to or directly a sealing ring) fitted onto the first end of the magnetic rod chuck 11. The elastic force of the elastic ring 15 causes the first end of the magnetic rod clamping block 12 to tend to press into the through hole 14. Therefore, by using multiple magnetic rod clamping blocks 12 surrounding the through hole 14, a portion of the magnetic rod 1 located in the through hole 14 can be clamped, maintaining the clamped state through elastic force.

[0025] It is worth mentioning that the elastic ring 15 used in this embodiment eliminates the need for separate linear springs or similar components for each magnetic rod clamp 12. This adapts to the annular distribution of the magnetic rod clamp 12, making material sourcing and installation more convenient. To improve the stability of the elastic ring 15 installation, annular grooves can be formed at the first end of the magnetic rod clamp 11 and the second end of the magnetic rod clamp 12, allowing the elastic ring 15 to be stably engaged in the grooves. Additionally, the first end of the magnetic rod clamp 12 can be chamfered or rounded, allowing the magnetic rod clamp 12 to be pushed outwards a small distance before maintaining the clamped state when the magnetic rod 1 is inserted.

[0026] In this embodiment, the second ejector part includes a second ejector rod 16, a second ejector seat 17, and a third drive module 18. The second ejector rod 17 and the magnetic rod chuck 11 are also configured in a one-to-one correspondence. The first end of the second ejector rod 17 is used to insert into the through hole 14 for ejection, and the second end of the second ejector rod 16 is fixedly connected to the second ejector seat 17. The second ejector seat 17 is connected to the third drive module 18, which is arranged on the fixture base 10 along a first direction and is used to drive the second ejector seat 17 to move along the first direction. Simultaneously, the through hole of the magnetic rod chuck 11 penetrates through the first and second ends of the magnetic rod clamping block 12. Therefore, the second ejector rod 16 can enter the through hole 14 and slowly eject the magnetic rod 1 completely from the first end of the magnetic rod chuck 11. This process is used for the assembly of the magnetic rod 1 and the coil. Obviously, when the magnetic rod chuck 11 is completely ejected from the through hole, the magnetic rod clamping block 12 no longer clamps the magnetic rod 1.

[0027] As mentioned in the background art, it is best to allow the magnetic rod 1 to rotate synchronously during the insertion of the coil to improve smoothness. Based on this, the magnetic rod positioning fixture in this embodiment also includes a rotary drive unit, which is used to directly drive the magnetic rod chuck 11 to rotate. Specifically, the position of the magnetic rod chuck 11 near its second end is rotatably connected to the fixture base 10 via a bearing. The rotary drive unit includes a motor 19, a driving synchronous pulley 20, a driven synchronous pulley 21, and a synchronous belt 22. Among them, the motor 19 is fixedly connected to the fixture base 10, and the driving synchronous pulley 20 is connected to the output shaft of the motor 19 to maintain synchronous rotation (by means of a key, etc.). The driven synchronous pulley 21 corresponds one-to-one with the magnetic rod chuck 11, is sleeved on the second end of the magnetic rod chuck 11 and rotates synchronously with the magnetic rod chuck 11, and the synchronous belt 22 is wound between the driving synchronous pulley 20 and the driven synchronous pulley 21, so that the motor 19 can simultaneously drive multiple magnetic rod chucks 11 to rotate synchronously.

[0028] Therefore, as the second ejector gradually pushes the magnetic rod 1 out of the magnetic rod chuck 11, the magnetic rod chuck 11 continues to rotate, causing the magnetic rod 1 to rotate, thus assembling with the coil by rotational insertion. Because the clamping force of the magnetic rod clamp block 12 is relatively large, this process allows the magnetic rod 1 to continue rotating until it is completely ejected from the magnetic rod chuck 11.

[0029] It should be noted that the various drive modules mentioned above can adopt forms commonly used in existing technologies, including but not limited to cylinders, lead screws, electric actuators, etc., in conjunction with guide rail sliders to drive in the corresponding direction. Their specific structures have not been described in detail above. Those skilled in the art can flexibly choose based on actual needs, including structural layout, control accuracy requirements, etc.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
