Description

Technical Field

[0001] This utility model relates to the field of magnetic ring inductor processing technology, and in particular to a semi-automatic magnetic ring hooking machine. Background Technology

[0002] Magnetic ring inductors are commonly used electronic components, such as PFC inductors, and are widely used in power electronic equipment such as charging piles. They are primarily used to optimize energy utilization, reduce harmonic pollution, and improve system stability. For magnetic ring inductors, since the magnetic ring forms a closed ring structure after manufacturing, the coil assembly process requires winding the coil sequentially onto the magnetic ring. Currently, most coil-to-magnetic ring winding is still done manually or with semi-automatic equipment. Semi-automatic equipment balances labor intensity, efficiency, and cost, and is still widely used in the actual production of magnetic ring inductors. However, conventional semi-automatic equipment is not very convenient for installing and disassembling the magnetic ring. During winding, the magnetic ring needs to be driven to rotate by a preset angle to wind the coil at different positions. Driving the rotation of the magnetic ring usually relies on static friction, which requires pressing the magnetic ring firmly to ensure sufficient static friction to prevent the stepper motor from driving the preset angle without actually rotating the magnetic ring. This can contradict the ease of installation and disassembly. Therefore, comprehensive improvements are needed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a device that is easy to install and disassemble, and accurately drives the rotation of the magnetic ring, thereby improving the efficiency and quality of coil winding.

[0004] To achieve the above objectives, this utility model provides a semi-automatic magnetic ring hooking machine, including a base and a magnetic ring positioning drive assembly and a hooking assembly connected to the base;

[0005] The hook assembly includes a hook, a hook connecting rod, a hook seat, and a hook driving module. The hook driving module is connected to the hook seat. The first end of the hook connecting rod is connected to the hook, and the second end of the hook connecting rod is fixedly connected to the hook seat. The end of the hook is hook-shaped.

[0006] The base is provided with a working slot for placing a magnetic ring. Multiple sets of magnetic ring positioning drive components are arranged around the working slot. Each set of magnetic ring positioning drive components includes a roller, a roller shaft, a positioning drive seat, a second motor, and a second slider. The base is provided with a guide groove. The second slider is slidably connected to the guide groove. The positioning drive seat is connected to the second slider. The roller is connected to the first end of the roller shaft and maintains synchronous rotation. The second end of the roller shaft is connected to the second motor through a transmission structure inside the positioning drive seat.

[0007] The magnetic ring positioning drive assembly also includes a mounting plate, a spring, and a quick clamp. The mounting plate is connected to the base. The spring is disposed between the mounting plate and the second slider. The quick clamp is disposed on the mounting plate and has an open position and a locked position. When the quick clamp is in the locked position, the quick clamp contacts the second slider and presses it toward the center of the working slot.

[0008] Furthermore, the hook is made of rigid plastic.

[0009] Furthermore, the hook drive module includes a first motor, a drive wheel, a driven wheel, a timing belt, a guide rail, and a first slider. The guide rail is connected to the base, and the first slider is connected to the hook seat. The first slider is slidably engaged with the guide rail. The first motor is mounted on the base, and the output shaft of the first motor is drivenly connected to the drive wheel. The driven wheel is rotatably connected to the base. The timing belt is wound between the drive wheel and the driven wheel, and a preset position of the timing belt is fixedly connected to the first slider.

[0010] Furthermore, the magnetic ring positioning drive assembly is provided in three groups, which are distributed at equal 120-degree intervals relative to the center of the working slot.

[0011] Furthermore, a washer is connected to the bottom of the roller, which can support the magnetic ring.

Detailed Implementation

[0021] 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.

[0022] 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.

[0023] 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.

[0024] like Figure 1 , Figure 2As shown, an embodiment of this utility model provides a semi-automatic magnetic ring hooking machine, including a base 1 and a magnetic ring positioning drive assembly and a hooking assembly connected to the base 1. The magnetic ring positioning drive assembly is used to position the magnetic ring, ensuring its stability during operation. It also drives the magnetic ring to rotate by a preset angle each time, so that after the previous segment of the magnetic ring has completed winding, the next segment rotates to face the operator for winding. The hooking assembly works in conjunction with the operator during winding. It hooks the nth position of the coil directly above the center of the magnetic ring, then passes through the center of the magnetic ring and is positioned below it. At this time, the end of the coil also passes through the center of the magnetic ring and is positioned below it. The operator then moves the (n+1)th position of the coil back to directly above the center of the magnetic ring and hooks it again. At this time, the end of the coil has completed one loop and is again positioned above the center of the magnetic ring. Then, the (n+1)th position of the coil passes through the center of the magnetic ring and is positioned below it, and the end of the coil again passes through the center of the magnetic ring and is positioned below it. This process is repeated to complete the winding of the coil.

[0025] In this embodiment, the hook assembly includes a hook 2, a hook connecting rod 3, a hook seat 4, and a hook driving module. The hook driving module is connected to the hook seat 4 and drives the hook seat 4 to move along a first direction. For example, corresponding to directly above and below the center of the magnetic ring, the first direction can be vertical. The first end of the hook connecting rod 3 is fixedly connected to the hook 2, and the second end is fixedly connected to the hook seat 4. The end of the hook 2 is hook-shaped to hook the corresponding position of the coil and simultaneously drive it through the center of the magnetic ring. The hook 2 is aligned with the center of the magnetic ring after the magnetic ring positioning drive assembly positions the magnetic ring. It should be noted that the hook 2 is typically made of hard plastic to hook the corresponding position of the coil without causing significant damage to the coil or injuring workers.

[0026] In one specific embodiment, the hook drive module includes a first motor 5, a driving wheel 6, a driven wheel 7, a timing belt 8, a guide rail 9, and a first slider 10. The guide rail 9 is fixedly connected to the base 1 and arranged along a first direction. The first slider 10 is fixedly connected to the hook seat 4 and slidably engaged with the guide rail 9. The first motor 5 is mounted on the base 1, and its output shaft is driven by the driving wheel 6 (via a reducer, etc.). The driven wheel 7 is rotatably connected to the base 1. The timing belt is wound between the driving wheel 6 and the driven wheel 7, and its preset position is fixedly connected to the first slider 10. Therefore, when the first motor 5 drives the driving wheel 6 to rotate forward or reverse, it enables the timing belt 8 to transport the hook in the forward or reverse direction, thereby moving the first slider 10 upward or downward, allowing the end of the hook 2 to pass through the center of the magnetic ring upward or downward. It is understood that the first motor 5 needs to be a type of motor with both forward and reverse rotation functions and high control precision.

[0027] Of course, in other specific embodiments, the hook drive module can also consider other types of linear reciprocating drive modules, such as lead screw type, cylinder type, etc., and those skilled in the art can make flexible choices based on control accuracy and operating cost.

[0028] At the same time, such as Figure 3 As shown, in this embodiment, a working slot 11 is provided on the base 1. The working slot 11 is used to place the magnetic ring, and the magnetic ring is positioned at the working slot 11 by a magnetic ring positioning drive assembly. Multiple sets of magnetic ring positioning drive assemblies are provided, such as the three sets shown in the figure, distributed at 120-degree intervals. Each set of magnetic ring positioning drive assemblies includes a roller 12, a roller shaft 13, a positioning drive seat 14, a second motor 15, and a second slider 16. Meanwhile, a guide groove 17 is provided on the base 1. A portion of the second slider 16 extends into the guide groove 17 and is slidably connected to the guide groove 17. The positioning drive seat 14 is fixedly connected to the second slider 16. The roller 12 is connected to the first end of the roller shaft 13 and rotates synchronously. The second end of the roller shaft 13 is rotatably connected to the second slider 16 via a bearing, and the second end of the roller shaft 13 extends into the positioning drive seat 14. The second motor 15 is connected to the positioning drive seat 14, and the output shaft of the second motor 15 is connected to the shaft of the roller 12 through a transmission structure inside the positioning drive seat 14. For example, the transmission structure can be a gear transmission structure, a belt transmission structure, etc. Therefore, the second motor 15 can drive the roller 12 to rotate.

[0029] In a preferred embodiment, a washer 18 is connected to the bottom of the roller 12. The edge of the washer 18 provides support for the magnetic ring, better preventing the magnetic ring from falling off during installation and disassembly. The surface of the roller 12 is made of a relatively rough material or has been roughened to increase the friction between it and the magnetic ring. In the configuration of multiple sets of magnetic ring positioning drive components, the contact surface formed by the inner sides of the multiple rollers 12 matches the outer diameter of the magnetic ring, so that each roller 12 can fully contact the magnetic ring and drive the magnetic ring to rotate.

[0030] In this embodiment, the guide groove 17 is radially distributed along the working groove 11, i.e., the center of the magnetic ring. When the second slider 16 moves along the guide groove 17, it can adjust the distance between the roller 12 and the center of the magnetic ring. This allows the roller 12 to open radially when the magnetic ring needs to be installed or removed, and then close radially after the magnetic ring is placed, thereby supporting and positioning the magnetic ring. It is understood that in actual operation, only one roller 12 can be opened radially, while the other two remain in the same position, which can also better prevent the magnetic ring from falling off.

[0031] In this embodiment, the magnetic ring positioning drive assembly further includes a mounting plate 19, a spring 20, and a quick clamp 21. The mounting plate 19 is fixedly connected to the base 1 and is positioned relative to the second slider 16. The spring 20 is disposed between the mounting plate 19 and the second slider 16, with both ends inserted into corresponding spring holes. The quick clamp 21 is mounted on the mounting plate 19 and has an open position and a locked position. When the quick clamp 21 is in the open position, it does not contact the second slider 16; when the quick clamp 21 is in the locked position, it contacts the second slider 16, simultaneously pressing the second slider 16 towards the center of the magnetic ring.

[0032] Therefore, when installing the magnetic ring, the quick clamp 21 can be switched to the open position first, and then the second slider 16 can be pulled to open the corresponding roller 12, compressing the spring 20. After placing the magnetic ring, the second slider 16 is released, and the second slider 16 can quickly close under the action of the spring 20 to prevent the magnetic ring from falling off. Finally, the quick clamp 21 is switched to the locked position, and the quick clamp 21 contacts and presses against the second slider 16 to prevent the magnetic ring from falling off during winding due to the elastic force of the spring 20 alone. As mentioned above, in actual operation, only one roller 12 can be opened radially. Therefore, in this embodiment, only one set of magnetic ring positioning drive components is equipped with the mounting plate 19, spring 20, and quick clamp 21. The other two sets of magnetic ring positioning components are not set. Their second slider 16 can be kept in the guide groove 17 and near the farthest position relative to the center of the magnetic ring. Under the action of the magnetic ring positioning drive components with spring 20 and quick clamp 21, the magnetic ring can be kept stable.

[0033] It is worth mentioning that the second motor 15 in this embodiment is a high-precision stepper motor, so that the magnetic ring can accurately rotate to the required angle each time. Therefore, the semi-automatic magnetic ring hooking machine provided in this embodiment is not only easy to install and disassemble, but also can accurately control the rotation angle of the magnetic ring, improving the efficiency and quality of coil winding.

[0034] 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.

[0035] 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.
