Description

Technical Field

[0001] The invention relates to the technical field of annular magnetic core processing, in particular to an automatic winding device for annular magnetic cores. Background Art

[0002] Small inductor components are commonly used electronic components in electronic products. During the manufacturing process, the magnetic core needs to be wound. The main function of the magnetic core winding is to use magnetic conductive materials (magnetic rings or magnetic cores) to gather the magnetic field and improve the inductance efficiency.

[0003] When winding the toroidal core, first fix the copper wire on the winder so that it can be wound into the magnetic ring smoothly, and select the appropriate wire diameter and number of windings. Then put the magnetic ring on the winder and start winding. Lead the copper wire from the winder and wind it along one side of the magnetic ring to keep the coil tight and uniform.

[0004] For example, the winding fixture for ring-shaped magnetic core inductors with patent number CN209168938U is adapted to different sizes. The magnetic core is placed between the three rubber rollers by adjusting the spacing between the three rubber rollers to achieve the clamping of the adaptive magnetic core, and the rubber rollers can synchronously drive the magnetic core to rotate, thereby achieving the winding process;

[0005] However, the above patent content only realizes adaptive clamping and self-rotation of the annular magnetic core. In the actual operation process, due to the inherent characteristics of the metal wire, when the metal wire is used to loop the annular magnetic core, the coil that is prone to bending may bulge in a local area, forcing the coil to be difficult to fit with the outer wall of the annular magnetic core;

[0006] In addition, although the magnetic core can be driven to rotate and perform circular winding, as the number of winding coils increases, the coils are easily unevenly distributed on the outside of the magnetic core and some coils are overlapped, which greatly affects the winding quality of the coils and reduces the processing quality of the annular magnetic core;

[0007] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 7 As shown, an automatic winding device for an annular magnetic core includes an operating frame 1, the front and rear end surfaces of the operating frame 1 are both provided with L-shaped notched grooves, the top surface of the operating frame 1 is provided with a supporting component 2, and a winding mechanism 3 is provided inside the operating frame 1;

[0034] The supporting assembly 2 includes two groups of fixed rotating cylinders 21 and one group of movable rotating cylinders 22. The two groups of fixed rotating cylinders 21 are rotatably connected to the top surface of the operating frame 1 and are located on one side of the two groups of L-shaped notched grooves, and the movable rotating cylinder 22 is movably arranged on the top surface of the operating frame 1 and is located at the center of the interval on the other side of the two groups of L-shaped notched grooves. The middle sections of the fixed rotating cylinders 21 and the movable rotating cylinders 22 are fixedly sleeved with a tray 23. The outsides of the two groups of fixed rotating cylinders 21 and located at the lower end of the tray 23 are fixedly sleeved with a transmission wheel 24, and the outsides of the two groups of transmission wheels 24 are commonly sleeved with a transmission belt;

[0035] In specific operation, a single group of annular magnetic cores are placed together at the edge of the top surface of the three groups of trays 23, and the edges of the annular magnetic cores are respectively against the edges of the fixed-point rotating drum 21 and the movable rotating drum 22. During the winding process, the motor 25 is started to drive one group of transmission wheels 24 and the fixed-point rotating drum 21 to rotate, and under the action of the transmission belt, the other group of transmission wheels 24 and the fixed-point rotating drum 21 are driven to rotate. The two groups of fixed-point rotating drums 21 rotate at the same time and jointly drive the uniform circular motion of the annular magnetic core, and the winding operation is performed in sequence through the winding mechanism 3;

[0036] In order to facilitate the taking of the annular magnetic core and accommodate the placement of annular magnetic cores of various sizes, the bottom of a set of fixed-point rotating cylinders 21 extends to the inner wall of the top of the operating frame 1 and is provided with a motor 25, the bottom of the movable rotating cylinder 22 is slidably connected to the inside of the slide groove provided on the top surface of the operating frame 1, and a cylinder 26 is provided between the bottom of the movable rotating cylinder 22 and the inner wall of one side of the slide groove through a push rod;

[0037] When the annular magnetic core is placed, the positions of the trays 23 of the two sets of fixed-point rotating drums 21 remain unchanged, then the cylinder 26 is started, and the push rod is used to push or pull the movable rotating drum 22 to move along the inside of the slide slot, forcing the movable rotating drum 22 and its tray 23 to approach or move away from the fixed-point rotating drum 21 until the distance between them is adapted to the diameter of the annular magnetic core, so as to adapt to the winding of magnetic cores of various specifications.

[0038] Example 2: Please refer to Figure 5 - Figure 7As shown, the winding mechanism 3 includes two groups of C-shaped fixed outer frames 31, which are respectively fixedly installed in the operating frame 1 at the front and rear end L-shaped notch grooves through the machine base, and the top half of the C-shaped fixed outer frame 31 extends to the outside of the operating frame 1. The inner walls of the two groups of C-shaped fixed outer frames 31 are respectively connected with a C-shaped movable inner frame 1 32 and a C-shaped movable inner frame 2 33 through a plurality of groups of double-axis rollers. The inner wall surfaces of the C-shaped movable inner frame 1 32 and the C-shaped movable inner frame 2 33 are provided with tooth groups, and the bottom inner walls of both are provided with a transmission assembly 34. The side center of the C-shaped movable inner frame 1 32 is rotatably connected with a wire storage drum 35.

[0039] The transmission assembly 34 includes a rectangular positioning plate 341, and the positioning plate 341 is arranged at the center of the inner wall of the bottom of the C-shaped movable inner frame 1 32, one side of the positioning plate 341 is fixedly connected to the end of a long rod fixedly installed on the inner wall of one side of the operating frame 1, and the front and rear ends of the positioning plate 341 away from the long rod are respectively connected to the limited gear 342 by a rotating rod, and the limited gear 342 is meshed with the tooth group, and one end of the rotating rod at the center of the two limited gears 342 extends to one side of the positioning plate 341 and is fixedly sleeved with a transmission wheel 2 343, and a transmission belt is commonly sleeved between the two transmission wheels 2 343, and a motor 2 344 is arranged at the end of one group of transmission wheels 2 343;

[0040] The specific winding process of the annular magnetic core includes: starting the second motor 344, which first drives one set of the second transmission wheel 343 and the limit gear 342 to rotate, and under the driving action of the transmission belt, forces the other set of the second transmission wheel 343 and the limit gear 342 to rotate continuously, and along with the continuous rotation of the two sets of limit gears 342, they mesh with the tooth group on the inner wall of the C-shaped movable inner frame 1 32 to achieve self-rotation;

[0041] The C-shaped movable inner frame 32 rotates relative to the C-shaped fixed outer frame 31, and the end of the wire end of the wire storage barrel 35 is firstly wound around the outside of the annular magnetic core in a small circle, and then the wire storage barrel 35 rotates with the C-shaped movable inner frame 32, and the wire storage barrel 35 and the C-shaped movable inner frame 32 continuously make a circle along the edge of the annular magnetic core. At the same time, the supporting component 2 drives the annular magnetic core to rotate, and the metal wire is evenly wound around the edge of the annular magnetic core;

[0042] It is worth noting that the distance between two adjacent sets of transmission wheels 2 343 is greater than the gap length of the C-shaped movable inner frame 1 32 or the C-shaped movable inner frame 2 33, so that when the C-shaped movable inner frame 1 32 or the C-shaped movable inner frame 2 33 is forced to rotate to the positioning plate 341, at most only one set of transmission wheels 2 343 is temporarily in a vacant position, and will not affect the continuous rotation of the C-shaped movable inner frame 1 32 or the C-shaped movable inner frame 2 33;

[0043] In addition, this embodiment is combined with the first embodiment, the rear end face of the movable rotating drum 22 is located at the top position of the tray 23 and a limit assembly 4 is provided through the stop bar 27, the limit assembly 4 includes a cross bar 41, the cross bar 41 is arranged in a deflected and inclined structure through the inside of the stop bar 27, and the cross bar 41 and the end away from the stop bar 27 are fixedly installed with a vertical sliding frame 42, the interior of the vertical sliding frame 42 is slidably connected with a slide bar 43 at both the upper and lower ends, an annular groove is provided at the middle section of the upper and lower groups of slide bars 43 and an elastic band 44 is jointly sleeved, the two groups of slide bars 43 are rotatably connected to the ends away from the vertical sliding frame 42, and the ends of the two groups of slide bars 43 away from the vertical sliding frame 42 are respectively rotatably connected with a stop barrel 45, and the ends of the two groups of stop barrels 45 away from the slide bars 43 are arranged with upper and lower symmetrical beveled surfaces;

[0044] When the metal wire is wound around the outer wall of the annular magnetic core, due to the characteristics of the metal wire itself, it is easy to have local bulges when it is bent and wound;

[0045] According to the first embodiment, while the cylinder 26 pushes the movable rotating cylinder 22 to move, the resistance bar 27 pushes the limit assembly 4 to approach the edge of the annular magnetic core, and the beveled ends of the upper and lower groups of resistance cylinders 45 are pressed against the upper and lower end surfaces of the arc-shaped magnetic core respectively and move upward or downward respectively, and the sliding rod 43 at the end of the resistance cylinder 45 slides along the inside of the vertical sliding frame 42, and the elastic band 44 is stretched until the upper and lower groups of resistance cylinders 45 are adaptively pressed and clamped at the edge of the annular magnetic core, thereby not only further clamping and fixing the annular magnetic core performing circular motion, increasing the stability of the annular magnetic core, but also further rolling and crushing the upper and lower end surfaces of the annular magnetic core that has been wound with the coil, thereby reducing the partial protrusion of the winding area of ​​the annular magnetic core, and further improving the winding effect of the annular magnetic core.

[0046] Example 3: Please refer to Figure 5 and Figure 7 As shown, the sides of the two transmission wheels 2 343 on the opposite sides of the two transmission components 34 are fixedly mounted with transmission wheels 345, and a transmission belt is also commonly sleeved between the front and rear transmission wheels 345;

[0047] A concave clamping frame 36 is fixedly installed on one side of the C-shaped movable inner frame 33 and at the front and rear corresponding positions of the wire storage barrel 35 through a connecting rod, and the upper and lower inner walls of the concave clamping frame 36 are located at the opening and are rotatably connected to a combing ball 37, and the circumferential surface of the combing ball 37 is provided with arc-shaped clamping grooves 38 at equal distances;

[0048] This embodiment is also coordinated with the second embodiment. When the second motor 344 drives the second transmission wheel 343 inside the first C-shaped movable inner frame 32 to rotate, it also drives one set of the third transmission wheel 345 to rotate. Under the driving action of the transmission belt, it drives the other set of the third transmission wheel 345 and the second transmission wheel 343 inside the second C-shaped movable inner frame 33 and its inner wall components to rotate. Similarly, the second C-shaped movable inner frame 33 is made to perform annular circular motion along the rear end frame of the annular magnetic core.

[0049] In the initial state, the combing ball 37 abuts against the edge surface of the annular magnetic rear end, and the coils on the outside of the annular magnetic core are respectively clamped in the corresponding surface slots 38 of the combing ball 37. When the combing ball 37 moves in a circular motion with the C-shaped movable inner frame 2 33, the coils on the edge of the annular magnetic core are conveniently combed in a circular manner, so as to keep the coils on the surface of the annular magnetic core evenly distributed and reduce the situation of coil overlap and winding;

[0050] It is worth noting that the combing ball 37 is rotatably connected to the inside of the concave clamping frame 36 at the upper and lower ends. Therefore, when the annular magnetic core rotates in a circle, the coil lines engage with the clamping grooves 38 of the combing ball 37 to realize the self-rotation of the combing ball 37, and will not cause movement obstruction to the rotating annular magnetic core.

[0051] Working principle: When the present invention is used, firstly, a single group of annular magnetic cores are placed together at the edge of the top surface of three groups of trays 23, and the edges of the annular magnetic cores are respectively against the edges of the fixed-point rotating drum 21 and the movable rotating drum 22. During the winding process, the motor 25 is started to drive one group of transmission wheels 24 and the fixed-point rotating drum 21 to rotate, and under the action of the transmission belt, the other group of transmission wheels 24 and the fixed-point rotating drum 21 are driven to rotate, and the two groups of fixed-point rotating drums 21 rotate at the same time and jointly drive the uniform circular motion of the annular magnetic core;

[0052] Then the second motor 344 is started, which first drives one set of the second transmission wheel 343 and the limit gear 342 to rotate, and under the driving action of the transmission belt, forces the other set of the second transmission wheel 343 and the limit gear 342 to rotate continuously, and along with the continuous rotation of the two sets of limit gears 342, they mesh with the teeth set on the inner wall of the C-shaped movable inner frame 1 32 to realize self-rotation;

[0053] The C-shaped movable inner frame 32 rotates relative to the C-shaped fixed outer frame 31, and the end of the wire end of the wire storage barrel 35 is firstly wound around the outside of the annular magnetic core in a small circle, and then the wire storage barrel 35 rotates with the C-shaped movable inner frame 32, and the wire storage barrel 35 and the C-shaped movable inner frame 32 continuously make a circle along the edge of the annular magnetic core. At the same time, the supporting component 2 drives the annular magnetic core to rotate, and the metal wire is evenly wound around the edge of the annular magnetic core;

[0054] At the same time, when the motor 2 344 drives the transmission wheel 2 343 inside the C-shaped movable inner frame 1 32 to rotate, it also drives one group of transmission wheels 3 345 to rotate. Under the transmission action of the transmission belt, it drives the other group of transmission wheels 3 345 and the transmission wheel 2 343 and its inner wall components inside the C-shaped movable inner frame 2 33 to rotate. Similarly, the C-shaped movable inner frame 2 33 makes a circular motion along the rear end frame of the annular magnetic core, and the combing ball 37 abuts against the rear end edge surface of the annular magnetic core, and the coils outside the annular magnetic core are respectively clamped in the corresponding surface grooves 38 of the combing ball 37. When the combing ball 37 makes a circular motion with the C-shaped movable inner frame 2 33, it is convenient to perform circular combing on the edge coils of the annular magnetic core.

[0055] When the ring core is wound, it can be removed.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
