Description

Technical Field

[0001] This invention relates to an automatic unwinding mechanism for magnetic winding and a magnetic winding machine thereof, belonging to the field of inductor winding production technology. Background Technology

[0002] In existing inductor winding machine production, the requirements for the final product shape of the wound magnetic ring are becoming increasingly diverse. Some require the tail wire of the wound magnetic ring to be wound around the inductor base pins, while others require the tail wire to be straightened. For these types of wound magnetic rings, the tail wire extends from the central hole of the magnetic ring before being processed into the desired product shape. However, when it is necessary to keep the tail wire tightly against the outer wall of the magnetic ring and extend it outwards, existing automatic magnetic ring winding machines cannot automate this process. This is because existing magnetic ring winding machines start winding from the center of the magnetic ring, and the tail wire eventually adheres to the inner wall of the magnetic ring. They cannot automatically achieve this adhesion to the outer wall; instead, they require manual unwinding of half a turn after winding to allow the tail wire to extend from the outer circumference of the magnetic ring.

[0003] Therefore, it is necessary to improve the existing automatic magnetic ring winding machine to implement the unwinding action, so that the tail wire finally sticks to the outer circumference of the magnetic ring and extends out. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic unwinding mechanism for magnetic winding that can automatically withdraw the tail wire from the hole in the magnetic ring to the outer wall.

[0005] Another object of the present invention is to provide a magnetic winding machine that applies the above-described unwinding mechanism.

[0006] This invention is achieved through the following technical solution:

[0007] An automatic unwinding mechanism for magnetic ring winding is characterized by including a movable magnetic ring clamping manipulator mounted on a frame, wherein the magnetic ring clamping manipulator has winding clamps above and below its clamping position, which are capable of clamping and moving the winding, and the frame is provided with a winding constraint clamp capable of moving to pull the winding head out of the magnetic ring's central hole.

[0008] The above-described magnetic winding automatic unwinding mechanism is characterized in that there are two winding constraint clamps, which are respectively located above and below the axial direction of the clamped magnetic ring. The two winding constraint clamps move relative to each other along the axial direction of the clamped magnetic ring, approaching or moving away from the end face of the magnetic ring. The clamping arm ends of the winding constraint clamps are provided with inward bends, which form a wire-bundling space with the clamping arms after closing.

[0009] The automatic unwinding mechanism for magnetic winding as described above is characterized in that the opening and closing direction of the winding clamp is perpendicular to the axial direction of the clamped magnetic ring, and the winding clamp keeps the winding head or winding tail on the magnetic ring aligned with the axial direction of the magnetic ring.

[0010] The above-described magnetic ring winding automatic unwinding mechanism is characterized in that the magnetic ring clamping manipulator, the winding clamp, and the winding constraint clamp are all connected to their respective movement drives and opening / closing drives; the frame is provided with a rotation drive that drives the magnetic ring clamping manipulator and the winding clamp to rotate together; and the output end of the rotation drive is provided with a movement drive that drives the magnetic ring clamping manipulator and the winding clamp to move together.

[0011] A magnetic ring winding machine using the above-mentioned unwinding mechanism is characterized by comprising a magnetic ring feeding unit, a winding feeding unit, a magnetic ring winding unit, a winding gathering unit for concentrating the windings on the periphery of the magnetic ring, an adhesive application unit, and a magnetic ring unwinding mechanism, all mounted on a frame. The frame is provided with a transfer unit for transferring magnetic rings between the various units and mechanisms. The transfer unit includes at least one movable clamping manipulator, and the clamping manipulator has winding clamps above and below its clamping position that are capable of clamping and moving the windings.

[0012] The magnetic ring winding machine described above is characterized in that the material transfer unit includes two movable clamping manipulators. Each clamping manipulator is provided with a winding clamp above and below it, which can clamp and move the winding wire. One clamping manipulator moves between the magnetic ring feeding unit and the magnetic ring winding unit and clamps the magnetic ring for winding and wire arrangement. The other clamping manipulator moves between the magnetic ring winding unit, the winding gathering unit, the adhesive application unit and the magnetic ring unwinding mechanism.

[0013] The magnetic ring winding machine described above is characterized in that the discharge end of the magnetic ring feeding unit is provided with a movable and rotatable first material transfer robot, which holds the magnetic ring and transfers it to the clamping robot for holding the wire.

[0014] The magnetic winding machine described above is characterized in that a second material transfer robot is provided between the magnetic winding unit and the winding and gathering unit, and the upper and lower parts of the second material transfer robot are respectively provided with wire holding clamps capable of holding the winding.

[0015] The magnetic winding machine described above is characterized in that the winding and gathering unit includes a winding clamp that can be opened and closed, and the winding clamp has an end face that can be attached to the peripheral wall of the magnetic ring.

[0016] The magnetic winding machine described above is characterized in that the frame is further provided with a winding and twisting unit and a take-up unit for performing subsequent actions on the unwinding magnetic ring.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The present invention relates to a winding unwinding mechanism. The winding clamp moves to retract part of the winding, forming a hook space in the hole of the magnetic ring. The winding constraint clamp moves and pulls the half-turn winding out of the hole of the magnetic ring to achieve winding unwinding. The winding head extends from the outer wall of the magnetic ring.

[0019] This invention keeps the beginning and end of the winding wire constrained from the magnetic winding process onwards. In subsequent processes such as wire gathering, adhesive application, and unwinding, there is no need to reposition the beginning and end of the winding wire, resulting in faster automated production.

[0029] The present invention will be further described in detail below with reference to specific embodiments.

[0030] like Figure 1-9As shown, an automatic unwinding mechanism for magnetic ring winding includes a movable magnetic ring clamping manipulator 61 mounted on a frame 100. Above and below the clamping position of the magnetic ring clamping manipulator 61 are respectively a winding clamping clamp 62 capable of clamping and moving the winding. The frame 100 is equipped with a winding constraint clamp 63 capable of moving to pull the winding head out of the central hole of the magnetic ring 504. When the magnetic ring is in the unwinding position, the two winding heads of the magnetic ring are respectively clamped by the winding clamping clamp 62. The winding clamping clamp 62 moves to move the winding head in the opposite direction, causing the winding to form a loop at the central hole of the magnetic ring. The winding constraint clamp 63 opens and moves to the looped winding, then closes to hook the winding, and then moves to pull out the winding, allowing the winding to extend freely from the outer wall of the magnetic ring 504.

[0031] Preferably, there are two winding constraint clamps 63, which are respectively located above and below the axial direction of the clamped magnetic ring. The two winding constraint clamps 63 move relative to each other along the axial direction of the clamped magnetic ring 504, approaching or moving away from the end face of the magnetic ring. The clamping arm 631 of the winding constraint clamp 63 has an inwardly bent part 632 at the end. After closing, it forms a wire-binding space with the clamping arm 631, which reduces the positioning accuracy requirement of the closed hook and allows the winding to move quickly and be pulled out.

[0032] Furthermore, the opening and closing direction of the winding clamp 62 is perpendicular to the axis of the clamped magnetic ring, and the winding clamp 62 keeps the winding head or tail on the magnetic ring aligned with the axis of the magnetic ring. This eliminates the need to reposition the clamped winding to avoid subsequent processing steps.

[0033] In one specific embodiment of the present invention, the magnetic ring clamping robot 61, the winding clamp 62, and the winding constraint clamp 63 are each connected to their respective movement drives and opening / closing drives. The frame 100 is provided with a rotation drive 64 that drives the magnetic ring clamping robot 61 and the winding clamp 62 to rotate together. The output end of the rotation drive 64 is provided with a movement drive 65 that drives the magnetic ring clamping robot 61 and the winding clamp 62 to move together. This facilitates the rotation and movement of the magnetic ring clamping robot 61 at this station and its docking with the stations before and after it, simplifies the overall structure, and reduces the overall size of the structure.

[0034] A magnetic ring winding machine employing the aforementioned unwinding mechanism includes a magnetic ring feeding unit 1, a winding feeding unit 2, a magnetic ring winding unit 3, a winding gathering unit 4 for concentrating the windings around the periphery of the magnetic ring, an adhesive application unit 5, and a magnetic ring unwinding mechanism 6, all mounted on a frame 100. The frame 100 is equipped with a transfer unit 7 for transferring magnetic rings between the various units and mechanisms. The transfer unit 7 includes at least one movable clamping manipulator 71. Each clamping manipulator 71 has a winding clamp 72 located above and below its clamping position, capable of clamping and moving the windings. During the transfer process, the winding clamp 72 maintains the axial integrity of the winding head and tail on the magnetic ring, preventing subsequent repositioning or clamping of the windings from interfering with the actions of subsequent workstations. It also facilitates the unwinding action of the magnetic ring, ensuring that the windings extend from the outer wall of the magnetic ring.

[0035] In a preferred embodiment of the present invention, the transfer unit 7 includes two movable gripping robots 71. Each gripping robot 71 has a winding clamp 72 above and below it, capable of gripping and moving the winding wire. One gripping robot 71 moves between the magnetic ring feeding unit 1 and the magnetic ring winding unit 3 to grip the magnetic ring for winding and arranging the wire. The other gripping robot 71 moves between the magnetic ring winding unit 3, the winding gathering unit 4, the adhesive application unit 5, and the magnetic ring winding unwinding mechanism 6. Each gripping robot 71 and the winding clamp 72 is correspondingly connected to a movement drive and an opening / closing drive. Multiple gripping robots 71 perform the transfer, reducing the travel distance of each robot, improving the continuity of multi-workpiece processing in automated magnetic ring winding, and achieving a higher degree of automation.

[0036] Furthermore, in order to improve the speed and efficiency of automated production, the discharge end of the magnetic ring feeding unit 1 is provided with a movable and rotatable first transfer robot 73, which holds the magnetic ring and transfers it to the clamping robot 71 that holds the cable.

[0037] Furthermore, a second transfer robot 74 is provided between the magnetic winding unit 3 and the winding and gathering unit 4. The second transfer robot 74 has wire clamps 741 above and below it, capable of holding the winding. The second transfer robot 74 transfers the winding between the two clamping robots 71, allowing the two clamping robots 71 to move only in two dimensions (up, down, left, and right), without needing to rotate or flip the magnetic rings to intersect, thus avoiding structural complexity. The second transfer robot 74 simplifies the structure of the transfer unit 7, provides faster movement response, and thereby improves automated production efficiency.

[0038] In a preferred embodiment of the present invention, the winding and gathering unit 4 includes a winding clamp 41 capable of opening and closing, and a movement drive and an opening and closing drive thereof. The winding clamp 41 has an end face 411 capable of contacting the peripheral wall of the magnetic ring. At the winding station, the winding clamp 41 docks with the corresponding clamping robot 71, so that its end face 411 contacts the peripheral walls on both sides of the winding on the outer wall of the magnetic ring 504. Then, the winding clamp 41 is driven to gather and concentrate the relatively dispersed winding on the outer wall, which facilitates the subsequent adhesive application process.

[0039] One embodiment of the adhesive application unit 5 of the present invention is as follows: Figure 5 As shown, it includes a glue feeding assembly 51, a glue cutting component 52, a tape clamping assembly 53, and a glue application roller assembly 54 that can move along the outer circumference of the magnetic ring to apply the glue, thereby realizing the automatic application of a set length of tape to the winding fixedly wrapped around the outer circumference of the magnetic ring.

[0040] In a preferred embodiment of the present invention, the frame 100 is further provided with a winding and twisting unit 8 and a take-up unit 9 for subsequent actions on the unwound magnetic ring. The winding and twisting unit 8 may include a wire gathering frame 81, a winding clamp 82, and a winding robot 83 capable of opening and closing the clamp on the magnetic ring and moving and rotating. When the unwound magnetic ring passes through the wire gathering frame 81, the released winding is pushed to one side. The winding robot 83 extends and clamps the magnetic ring passing through the wire gathering frame 81. During the return movement of the winding robot 83, the winding clamp 82 closes and clamps all the wire ends that have been gathered to one side and straightens the winding ends during the movement. Finally, with the winding ends clamped, the winding robot 83 rotates to twist the winding ends together.

[0041] In this invention, the magnetic ring feeding unit 1, the winding and feeding unit 2, the magnetic ring winding unit 3, and the adhesive application unit 5 can all be other structures in the prior art, and are not limited to the specific structures described in this invention. After the magnetic ring 504 completes winding in the magnetic ring winding unit 3, as... Figure 7 As shown, after the processes of the winding and gathering unit 4 and the adhesive application unit 5, as indicated... Figure 8 As shown, the winding wire on the outer peripheral wall of the magnetic ring 504 is concentrated and fixed with adhesive tape 505. The free end of the winding wire still protrudes from the central hole of the magnetic ring. The winding magnetic ring 504 completes the unwinding action in the winding unwinding mechanism 6, so that the free end of the winding wire protrudes axially from the outer wall of the magnetic ring, as shown. Figure 9 As shown, this invention maintains a constrained state on the free end of the winding on the magnetic ring 504 from the magnetic winding station. This eliminates the need for repositioning or constraining the free end of the winding in subsequent winding, gluing, and unwinding processes, enabling rapid and automated unwinding of the free end of the winding magnetic ring. Simultaneously, it increases the turnover speed of the magnetic ring 504 in each process. The rational planning of multiple gripping robots in the material transfer unit 7 maximizes the efficiency of the automated production process.
