[0002] The transformer commonly used in the power industry is a conversion device that uses the principle of electromagnetic induction to change the AC voltage. It has the functions of voltage conversion, current conversion, impedance conversion, etc. The main components of the transformer are the primary coil, the secondary coil and the iron core. The main functions of the transformer are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. The micro transformer is a miniaturized power conversion device that plays an important role in modern electronic technology and power systems. With the development of electronic equipment towards miniaturization and thinness, higher requirements are placed on the volume and weight of micro transformers. In the future, micro transformers will continue to develop in the direction of smaller size and higher integration to meet the needs of various portable and high-density integrated electronic devices. In the process of transformer manufacturing, the wire needs to be wound around the coil frame to form a coil to complete the preparation work for transformer manufacturing.

As the connecting plate moves to the side away from the cylinder and under the connection of the bracket, the rolling wheel moves to the side close to the force-bearing plate, and contacts the force-bearing plate through the rolling wheel.

[0021] The present invention provides a micro transformer coil automatic winding device, which has the following beneficial effects:

[0022] 1. The automatic winding equipment for micro transformer coils puts the coil skeleton on the cylinder and uses the tapered end of the limiting cone to insert into the inside of the cylinder to limit the coil skeleton, making it difficult for the coil skeleton to deviate and fall off, which is helpful for accurate winding of the micro transformer coil and uses the interaction between the structures to connect the structures together.

[0023] 2. The automatic winding equipment for the micro transformer coil inserts the tip of the limiting cone into the interior of the cylinder. The conical surface of the limiting cone applies a pushing force to the support sheet, so that the support sheet rotates outward from the straight hole to adjust the angle, and the ring spring is stretched. The edge of the supporting sheet contacts the inner side of the coil frame, so that the inner side of the coil frame can be supported and fixed, thereby preventing the coil frame from slipping.

[0024] 3. The automatic winding equipment for the micro transformer coil uses the inner side of the coil frame to be supported and fixed by the support sheet, and under the limitation of the limiting cone, uses the output end of the main machine to rotate, and under the fixed installation of the coupling, the cylinder is driven to rotate, thereby driving the coil frame to rotate together, and automatic winding work can be performed. The limiting cone can be used for rotation, so that the cylinder drives the coil frame to rotate smoothly, and the structure is not prone to jamming.

[0025] 4. The automatic winding equipment for micro transformer coil utilizes the extension of the telescopic end of the cylinder to make the telescopic end of the cylinder exert a pushing force on the I-shaped slider. The I-shaped slider drives the connecting plate to move to the side away from the cylinder, so that the limiting cone can move with the connecting plate. The limiting cone is moved out of the cylinder and separated from the cylinder, so that the micro transformer coil that has been wound can be removed easily, making the installation and disassembly of materials convenient.

[0026] 5. The automatic winding equipment for the micro transformer coil, along with the continuous movement of the rolling wheel, causes the force plate to be subjected to the rolling force of the rolling wheel, and under the sliding connection of the slide seat, causes the sleeve and the reinforcing rod to move downward together, and the arc-shaped spring piece is compressed and elastically deformed. As the sleeve moves downward, the wire wound on the coil can be pressed and tensioned, and the wire is not prone to looseness, thereby making full use of the interaction between the structures to connect the structures together.

[0027] 6. The automatic winding equipment for the micro transformer coil uses the wire to bypass the groove on the top of the guide wheel and pass through the center hole of the wire barrel. Under the guidance of the wire barrel, the wire can be limited so that the wire is not easily skewed. When winding, as the wire moves, the guide wheel will roll, using rolling friction to reduce friction, which helps the wire move smoothly and facilitates the transportation and loading of the wire.

[0028] 7. The automatic winding equipment for the micro transformer coil utilizes the output end of the servo motor to rotate, and under the fixed installation of the coupling, the lead screw is driven to rotate, and the moving block is driven to move linearly through the support of the support legs, so that the guide assembly as a whole is driven to move, and the output end of the servo motor is used for forward and reverse rotation, so that the moving block drives the guide assembly as a whole to reciprocate, so that the wire output from the wire barrel can be evenly wound on the coil frame.

[0040] The first embodiment, as Figures 1 to 7 As shown, the present invention provides a technical solution:

[0041] A micro transformer coil automatic winding device comprises a body 1, and a rectangular hole 2 is opened at the side of the top of the body 1;

[0042] A driving mechanism 3, which is used to drive the coil frame to automatically wind the wire, and the driving mechanism 3 is installed on the top of the body 1 and close to the rectangular hole 2;

[0043] The driving mechanism 3 includes a main machine 31 and a tensioning assembly 32. The main machine 31 is fixedly mounted on the side of the top of the machine body 1, and the position of the main machine 31 corresponds to the position of the rectangular hole 2. The tensioning assembly 32 is mounted on the side of the outer surface of the main machine 31. A cylinder 33 is fixedly mounted on the output end of the main machine 31 through a coupling. A straight hole 34 is provided in the middle of the outer surface of the cylinder 33. A support sheet 35 is hingedly connected to the inner wall of the cylinder 33 near the straight hole 34. A through hole 36 is provided in the middle of the surface of the support sheet 35. A coil spring 37 is installed on the outer surface of the support sheet 35 near the through hole 36. The coil spring 37 passes through the center of the through hole 36.

[0044] The cylinder 33 is installed horizontally, and there are three support plates 35 , which are evenly installed inside the cylinder 33 .

[0045] There are three straight-line holes 34 , and the three straight-line holes 34 are evenly arranged on the outer circumferential surface of the cylinder 33 . The positions of the support sheets 35 correspond to the positions of the straight-line holes 34 .

[0046] A pressing mechanism 4, which is used to limit the position of the coil skeleton, and is installed on the top of the body 1 and close to the rectangular hole 2;

[0047] Among them, the top pressing mechanism 4 includes a cylinder 41 and an I-shaped slider 42. The cylinder 41 is fixedly installed at the bottom of the inner cavity of the body 1 and close to the rectangular hole 2. The I-shaped slider 42 is slidably installed between the rectangular hole 2 and the top of the body 1. The bottom of the I-shaped slider 42 is fixedly connected to the telescopic end of the cylinder 41. A connecting plate 43 is fixedly installed on the top of the I-shaped slider 42. A limiting cone 44 is rotatably installed on the surface of the connecting plate 43 and on one side close to the cylinder 33. A bracket 45 is fixedly installed in the middle of the edge of the surface of the connecting plate 43. A rolling wheel 46 is rollingly installed on the end of the bracket 45 away from the connecting plate 43. The staff puts the coil skeleton on the cylinder 33 and uses the tapered end of the limiting cone 44 to insert into the interior of the cylinder 33, so as to limit the coil skeleton, so that the coil skeleton is not easy to deviate and fall off, which is helpful for accurate winding of the micro transformer coil.

[0048] The staff turns on the cylinder 41 to work, and uses the contraction of the telescopic end of the cylinder 41 to apply a pulling force to the I-shaped slider 42. Under the limitation and guidance of the rectangular hole 2, the I-shaped slider 42 drives the connecting plate 43 to move to the side close to the cylinder 33, so that the limiting cone 44 can move with the connecting plate 43, and the tip of the limiting cone 44 is inserted into the interior of the cylinder 33. The conical surface of the limiting cone 44 applies a pushing force to the support sheet 35, so that the support sheet 35 rotates outward from the I-shaped hole 34 to adjust the angle, and the ring spring 37 is stretched, and the edge of the support sheet 35 is used to contact the inner side of the coil skeleton, so that the inner side of the coil skeleton can be supported and fixed.

[0049] The tip of the limiting cone 44 faces the cylinder 33, and the limiting cone 44 and the cylinder 33 are installed at the same height. The inner side surface of the coil skeleton is supported and fixed by the supporting plate 35. Under the limitation of the limiting cone 44, the staff turns on the main machine 31 to work, and rotates the output end of the main machine 31. Under the fixed installation of the coupling, the cylinder 33 is driven to rotate, thereby driving the coil skeleton to rotate together, and automatic winding work can be performed. The limiting cone 44 can be rotated, so that the cylinder 33 drives the coil skeleton to rotate smoothly.

[0050] When the winding of the coil skeleton is completed, the staff starts the cylinder 41 again to work, and uses the extension of the telescopic end of the cylinder 41 to make the telescopic end of the cylinder 41 apply a pushing force to the I-shaped slider 42. The I-shaped slider 42 drives the connecting plate 43 to move to the side away from the cylinder 33, so that the limiting cone 44 can move with the connecting plate 43, and the limiting cone 44 is moved out of the interior of the cylinder 33, and the limiting cone 44 is separated from the cylinder 33, so that the micro transformer coil that has been wound can be removed easily, making the material installation and disassembly convenient.

[0051] The second embodiment is based on the first embodiment. Figures 1 to 7 As shown:

[0052] The tensioning assembly 32 includes a rectangular guide rail 321, which is fixedly connected to the side of the outer surface of the main machine 31 by screws, and a strip notch 322 is opened in the middle of the surface of the rectangular guide rail 321. A slide seat 323 is slidably installed in the inner cavity of the rectangular guide rail 321, and an arc-shaped spring piece 324 is fixedly installed between the bottom of the slide seat 323 and the bottom of the inner side of the strip notch 322. A sleeve 325 is rollingly installed on the end of the slide seat 323 away from the rectangular guide rail 321 through a round rod, and a reinforcing rod 326 is fixedly installed between the bottom of the slide seat 323 and the end of the round rod and close to the sleeve 325. A force plate 327 is fixedly installed on the end of the reinforcing rod 326 away from the slide seat 323, and the position of the force plate 327 corresponds to the position of the rolling wheel 46.

[0053] As the connecting plate 43 moves toward the side away from the cylinder 33 and under the connection of the bracket 45, the rolling wheel 46 moves toward the side close to the force-bearing plate 327, and contacts the force-bearing plate 327 through the rolling wheel 46. As the rolling wheel 46 continues to move, the force-bearing plate 327 is subjected to the rolling force of the rolling wheel 46, and under the sliding connection of the slide seat 323, the sleeve 325 and the reinforcing rod 326 move downward together, and the arc-shaped spring piece 324 is compressed and elastically deformed. As the sleeve 325 moves downward, the coil-wound wire can be pressed and tensioned.

[0054] The position of the arc-shaped spring piece 324 corresponds to the position of the strip-shaped notch 322 , the reinforcing rod 326 is installed directly below the sleeve 325 , and the force-bearing plate 327 is installed at an angle.

[0055] The third embodiment is based on the first and second embodiments. Figures 1 to 9 As shown:

[0056] An auxiliary mechanism 5 is installed at the top of the body 1 and at one end away from the rectangular hole 2. The auxiliary mechanism 5 includes a screw rod 51 and a guide groove body 52. ​​The screw rod 51 is rotatably installed at the top of the body 1 and at one end away from the rectangular hole 2 through a base. The guide groove body 52 is fixedly installed at the top of the body 1 and close to the screw rod 51. A servo motor 53 is fixedly installed at the side of the top of the body 1 and close to the screw rod 51. The output end of the servo motor 53 is fixedly installed between the screw rod 51 through a coupling. A moving block 54 is threadedly installed at the threaded groove on the outer cylindrical surface of the screw rod 51. Support legs 55 are fixedly installed on both sides of the corresponding moving block 54. A ball 56 is rollingly installed at the bottom end of the support leg 55. A guide assembly 57 is installed on the top of the moving block 54.

[0057] There are two guide grooves 52 , and the two guide grooves 52 are symmetrically installed along the screw rod 51 , and the spherical surface at the bottom of the ball 56 fits with the inner cavity of the guide groove 52 .

[0058] The guide assembly 57 includes a flat plate 571, which is fixedly installed on the top of the moving block 54 by bolts. A bending rod 572 is fixedly installed on the side of the top of the flat plate 571, and a wire barrel 573 is fixedly installed on the top of the bending rod 572. A Y-shaped frame 574 is fixedly installed on the top of the flat plate 571 and close to the bending rod 572. A guide wheel 575 is rollingly installed on the top of the Y-shaped frame 574. The wire is passed around the groove on the top of the guide wheel 575 and passed through the center hole of the wire barrel 573. Under the guidance of the wire barrel 573, the wire can be limited so that the wire is not easily skewed. When winding, as the wire moves, the guide wheel 575 will roll, and rolling friction is used to reduce friction, which helps the wire move smoothly and facilitates the transportation and loading of the wire.

[0059] The wire barrel 573 is installed at an angle, the wire inlet of the wire barrel 573 is an arc-shaped curling, and the wire outlet of the wire barrel 573 is conical. The staff turns on the servo motor 53 to work, and uses the output end of the servo motor 53 to rotate, and under the fixed installation of the coupling, the lead screw 51 is driven to rotate, and the moving block 54 is driven to move in a straight line through the support of the support leg 55, so that the guide assembly 57 is driven to move as a whole, and the output end of the servo motor 53 is used for forward and reverse rotation, so that the moving block 54 drives the guide assembly 57 to move back and forth as a whole, so that the wire output from the wire barrel 573 can be evenly wound around the coil frame.

[0060] When in use, the staff first puts the coil frame on the cylinder 33, and passes the wire around the groove on the top of the guide wheel 575 and through the center hole of the wire cylinder 573;

[0061] At this time, the staff starts the cylinder 41 to work, and uses the contraction of the telescopic end of the cylinder 41 to apply a pulling force to the I-shaped slider 42. Under the limitation and guidance of the rectangular hole 2, the I-shaped slider 42 drives the connecting plate 43 to move to the side close to the cylinder 33, so that the limiting cone 44 can move together with the connecting plate 43, and the tip of the limiting cone 44 is inserted into the inside of the cylinder 33. The conical surface of the limiting cone 44 applies a pushing force to the support sheet 35, so that the support sheet 35 rotates outward from the I-shaped hole 34 to adjust the angle, and the ring spring 37 is stretched, and the edge of the support sheet 35 is used to contact the inner side of the coil frame, so that the inner side of the coil frame can be supported and fixed, and one end of the wire is fixedly installed at the specified position of the coil frame;

[0062] As the connecting plate 43 moves to the side away from the cylinder 33 and is connected to the bracket 45, the rolling wheel 46 moves to the side close to the force-bearing plate 327, and the rolling wheel 46 contacts the force-bearing plate 327. With the continuous movement of the rolling wheel 46, the force-bearing plate 327 is subjected to the rolling force of the rolling wheel 46. Under the sliding connection of the slide seat 323, the sleeve 325 and the reinforcing rod 326 move downward together, and the arc-shaped spring sheet 324 is compressed and elastically deformed. As the sleeve 325 moves downward, the wire wound on the coil can be pressed and tensioned.

[0063] The staff turns on the host 31 to work, and uses the output end of the host 31 to rotate, and under the fixed installation of the coupling, the cylinder 33 is driven to rotate, thereby driving the coil frame to rotate together, and the automatic winding work can be carried out, and the limiting cone 44 can be rotated, so that the cylinder 33 drives the coil frame to rotate smoothly, and the winding can be carried out;

[0064] At the same time, the conical end of the limiting cone 44 is inserted into the cylinder 33 to limit the coil frame, so that the coil frame is not easy to deviate or fall off, which is helpful for accurate winding of the micro transformer coil;

[0065] The staff turns on the servo motor 53 to work, and uses the output end of the servo motor 53 to rotate. Under the fixed installation of the coupling, the lead screw 51 is driven to rotate, and the moving block 54 is driven to move linearly through the support of the support leg 55, so that the guide assembly 57 is driven to move as a whole, and the output end of the servo motor 53 is rotated forward and reversely, so that the moving block 54 drives the guide assembly 57 to reciprocate as a whole, so that the wire output from the wire barrel 573 can be evenly wound on the coil frame;

[0066] Under the guidance of the wire barrel 573, the wire can be limited so that the wire is not easily skewed. When winding, as the wire moves, the guide wheel 575 will roll, using rolling friction to reduce friction, which helps the wire move smoothly and facilitates the wire transportation and feeding.

[0067] When the winding of the coil skeleton is completed, the main machine 31 is stopped, and the staff starts the cylinder 41 again to work. The telescopic end of the cylinder 41 is extended to make the telescopic end of the cylinder 41 apply a pushing force to the I-shaped slider 42. The I-shaped slider 42 drives the connecting plate 43 to move to the side away from the cylinder 33, so that the limiting cone 44 can move with the connecting plate 43. The limiting cone 44 is moved out of the interior of the cylinder 33, and the limiting cone 44 is separated from the cylinder 33, so that the micro transformer coil that has been wound can be removed easily, making the material installation and disassembly convenient.
