Description

Technical Field

[0001] The invention relates to the technical field of magnetic ring winding, and in particular to a winding device and a winding method for a winding machine. Background Art

[0002] The cross-winding (also known as butterfly-winding) inductor coil requires winding from the middle of the entire wire, and then winding the remaining half of the wire after winding half of the wire, due to its unique wiring method.

[0003] At present, the winding machines of this type of coils on the market mostly use the coaxial feeding method before winding. This method relies on the rolling of two rubber wheels to feed the wire downward. The servo motor controls the rotation angle of the rubber wheels to determine the length of the wire to be fed out. See Fig.11 This method has the following disadvantages:

[0004] The wire feeding mechanism occupies the space above the magnetic ring, which greatly limits the design of the winding and arranging mechanisms. The wire feeding length is not accurate enough. After a period of use, the rubber wheel will be dented by the wire and may slip, affecting the accuracy of the wire length.

[0005] When the wire length of the product is relatively long, the tail of the wire delivered will be uncontrolled, and problems such as wire deformation and bending will often occur, causing the wire to be wrapped around other mechanisms, causing the wire to become tangled, broken, and the insulation layer to be damaged. Summary of the invention

[0006] The invention aims at solving the existing technical problems and provides a wire feeding device and a wire feeding method for a winding machine.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a wire winding device for a winding machine, comprising a wire feeding mechanism, a thread end clamping mechanism, a wire hook reel and a hook needle, the wire feeding mechanism is used to transport the thread end of the wire to the thread end clamping mechanism, the thread end clamping mechanism is used to clamp or loosen the thread end of the wire, the hook needle is used to pass through the inner hole of the magnetic ring to hook the wire to the other side of the magnetic ring, the wire hook reel is provided with a wire hook, the wire hook is used to hook the wire between the magnetic ring and the hook needle, the wire hook reel is installed on a rotating drive device, the wire hook reel rotates under the action of the rotating drive device and winds the end of the wire with the thread end around the wire hook reel.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows:

[0009] Preferably, the wire feeding mechanism is installed on a mobile driving mechanism, a wire tube is installed on the mobile driving mechanism, and the wire feeding mechanism transports the wire ends of the wires to the wire end clamping mechanism through the wire tube.

[0010] Preferably, a groove opening is provided on the wire hook.

[0011] Preferably, the groove opening is U-shaped, V-shaped or arc-shaped.

[0012] Preferably, a roller is provided at the bottom of the groove opening.

[0013] Preferably, it also includes a wire dial, which is rotatable and has a plurality of wire dial holes circumferentially arranged thereon, wherein the wire dial holes are located between the hook needle and the magnetic ring.

[0014] Preferably, it also includes a clamping mechanism, and the clamping mechanism is used to clamp the magnetic ring.

[0015] The present invention also discloses a wire feeding method for a winding machine, comprising the wire feeding device as described above, and the specific steps are as follows:

[0016] Step S1: the wire feeding mechanism feeds the wire ends of the wires to the wire end clamping mechanism, and the wire end clamping mechanism clamps the wire ends of the wires; then the wire feeding mechanism retreats to avoid the position of the magnetic ring to make room above the magnetic ring;

[0017] Step S2: the hook needle moves toward the direction of the magnetic ring and passes through the inner hole of the magnetic ring, hooks the wire and moves downward to pull the wire to the other side of the magnetic ring;

[0018] Step S3: the hook is rotated at a certain angle to change the arrangement direction of the wires on both sides of the hook so that one of the wires enters the hooking range of the wire hook;

[0019] Step S4: the hooking disc rotates, and the hook takes the wire within the hooking range;

[0020] Step S5: the hook wire drum continues to rotate, and the wire feeding mechanism continues to release the wire while maintaining a certain tension on the wire until the wire of the required length is wound onto the hook wire drum;

[0021] Step S6: the wire feeding mechanism clamps the wire, the wire end clamping mechanism releases the wire end of the wire, and the wire hook drum continues to rotate, so that the end of the wire with the wire end is completely wrapped around the outer circumference of the wire hook drum.

[0022] Preferably, the step S4 further comprises the hook moving upward to separate from the wire, and then the hook rotating in the opposite direction by a certain angle and then moving downward.

[0023] The beneficial effects of the present invention are as follows: the wire is fed to the wire end clamping mechanism through the wire feeding mechanism, and the wire is hooked by the hook needle. The wire feeding mechanism can move back and forth under the drive of the mobile driving mechanism, and will not occupy the space above the magnetic ring, thereby ensuring that the winding and wire arranging mechanisms have sufficient installation space and reducing the design difficulty; by winding the wire with the wire end on the hook wire reel and setting the rotation angle of the hook wire reel according to the length of the wire, the length of the wire can be accurately controlled to ensure that the wound coil meets the design requirements; because the wire end is wound on the hook wire reel and a protective cover can be provided on the outside of the hook wire reel, it can be ensured that the wire is always stored in the wire holding space between the hook wire reel and the protective cover, and the position of the wire tail can be controlled to prevent the wire from being wound into other equipment, thereby solving the problems of the wire being knotted, broken or the insulation layer being damaged.

[0024] At the same time, the outer circumference of the hook wire reel is 3.14 times its diameter. Winding the wire on the hook wire reel can greatly reduce the size of the wire storage mechanism. The wire hook on the hook wire reel is smooth and the groove opening has a large bending radius, which can greatly reduce the bending degree of the wire when it is bypassed, avoid bending the wire at a large angle, ensure the insulation layer on the surface of the wire is not damaged, and ensure the flatness of the wire to avoid deformation of the wire.

DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0039] Reference Figures 1 to 10 As shown, the present invention discloses a wire winding device for a winding machine, comprising a wire feeding mechanism 1, a wire end clamping mechanism 5, a wire hooking reel 6 and a hook needle 9. The wire feeding mechanism 1 is used to convey the wire end of a wire 11 to the wire end clamping mechanism 5. In this embodiment, the wire 11 is a copper wire. The wire end clamping mechanism 5 is used to clamp or loosen the wire end of the wire 11. The hook needle 9 is used to pass through the inner hole of a magnetic ring 4 to hook the wire 11 to the other side of the magnetic ring 4. In this embodiment, the hook needle 9 hooks the wire above the magnetic ring 4. The wire 11 is hooked to the bottom of the magnetic ring 4, and a wire hook 7 is provided on the outer circumference of the hook wire drum 6. The wire hook 7 is used to hook the wire 11 between the magnetic ring 4 and the hook needle 9. The hook wire drum 6 is installed on the rotating drive device 12. The hook wire drum 6 rotates under the action of the rotating drive device 12 and winds the end of the wire 11 with the thread end around the hook wire drum 6, wherein the thread end clamping mechanism 5 is installed on the frame (not shown in the figure), and the thread end clamping mechanism 5 includes a thread end clamping claw for grabbing the thread end of the wire 11. The magnetic ring 4 is a circular magnetic ring or a rectangular magnetic ring.

[0040] In an optional embodiment, the wire 11 may also be a winding wire such as copper-clad aluminum wire or aluminum wire. The wire can be wound on an annular ring through the wire-winding device to meet the usage requirements in different environments and improve the scope of application.

[0041] In this embodiment, specifically, the wire feeding mechanism 1 is installed on the mobile driving mechanism 3, and the wire tube 2 is installed on the mobile driving mechanism 3. The wire feeding mechanism 1 transmits the wire end of the wire 11 to the wire end clamping mechanism 5 through the wire tube 2. The mobile driving mechanism 3 is an external slide rail cylinder, and the wire feeding mechanism 1 and the wire tube 2 are both installed on the slider of the external slide rail cylinder. The slider moves along the slide rail, thereby driving the wire feeding mechanism 1 and the wire tube 2 to move synchronously. The end of the mobile driving mechanism 3 is located on one side of the magnetic ring 4 and does not occupy the space above the magnetic ring 4. The wire tube 2 is installed on the mobile driving mechanism 3 through a fixed block, and the fixed block is installed on the mobile driving mechanism 3 through a vertically arranged long strip hole. Therefore, the height of the fixed block and the wire tube 2 can be adjusted to improve the convenience of use; the wire tube 2 supports, positions and flattens the wire 11, which facilitates the wire end clamping mechanism 5 to clamp the wire end of the wire 11, and allows the wire 11 to move along the wire tube 2, thereby reducing the bending and knotting of the wire 11.

[0042] In this embodiment, specifically, the wire hook 7 is provided with a groove opening, the groove opening is U-shaped, V-shaped or arc-shaped, a roller 13 is provided at the bottom of the groove opening, or the wire hook 7 is made of Teflon as a whole, in order to reduce the friction between the wire hook 7 and the wire 11. The direction of the groove opening is the same as the rotation direction of the hook wire reel 6, and the roller 13 can reduce the wear of the wire hook 7 on the wire 11, reduce the damage of the wire 11, and ensure the smooth movement of the wire 11 along the wire hook 7.

[0043] The winding machine threading device further comprises a thread-pulling disc 8, which is rotatable and has a plurality of thread-pulling holes 8.1 evenly arranged circumferentially thereon. The thread-pulling holes 8.1 are located between the hook needle 9 and the magnetic ring 4. The hook needle 9 passes through the wire-pulling hole 8.1 and the inner hole of the magnetic ring 4, and hooks the wire 11. The wire hook 7 hooks the wire 11 on one side of the hook needle 9 and continues to rotate with it. At this time, the hook needle 9 moves upward for a distance to separate from the wire 11. Then the hook needle 9 rotates in the opposite direction at a certain angle, such as 90°, and then moves downward, thereby releasing the wire 11. The wire feeding mechanism 1 continues to release the wire while maintaining a certain tension on the wire 11, so that the wire 11 is wound on the hook wire reel 6. When the hook wire reel 6 rotates to the set angle, it means that a sufficiently long wire 11 is wound on the hook wire reel 6. Then the wire feeding mechanism 1 clamps the wire 11 and no longer releases the wire. The thread end clamping mechanism 5 releases the thread end, and the hook wire reel 6 continues to rotate, so that the thread end part of the wire 11 completely passes through the wire-pulling hole 8.1 and is wound on the hook wire reel 6. At this point, the automatic threading is completed. The wire-moving hole 8.1 limits the horizontal movement range of the wire 11, so as to ensure that when the wire hook 7 carries the wire 11 for winding, the wire 11 does not tilt too much relative to the magnetic ring 4.

[0044] The wire dial 8 is driven by a driving device such as a driving motor to rotate, and another wire dial hole 8.1 is rotated to the bottom of the magnetic ring 4. The hook needle 9 and the wire hook 7 repeat the above action again, and the wires 11 are hooked in different wire dial holes 8.1, which plays a role in dividing the wires 11, avoiding the situation that the longer wires 11 are entangled with each other, and improving the smoothness of subsequent operations on the wires 11.

[0045] The winding machine threading device also includes a clamping mechanism 10, which is used to clamp the magnetic ring 4. The clamping mechanism 10 includes a clamping cylinder and a clamping claw, which is installed on the frame. The clamping cylinder drives the clamping claw to clamp the magnetic ring 4, which is convenient for threading the magnetic ring 4.

[0046] The present invention also discloses a wire feeding method for a winding machine, comprising the wire feeding device as described above, and the specific steps are as follows:

[0047] Step S1: The wire feeding mechanism 1 conveys the wire end of the wire 11 to the wire end clamping mechanism 5, and the wire end clamping mechanism 5 clamps the wire end of the wire 11. Specifically, the wire 11 drawn from the wire drum passes through the wire feeding mechanism 1 and the wire tube 2, and a section of the wire end is exposed outside the wire tube 2. The wire feeding mechanism 1 clamps the wire 11, and the mobile driving mechanism 3 drives the wire feeding mechanism 1 and the wire tube 2 to move toward the wire end clamping mechanism 5 until above the magnetic ring 4. The moving process will drag the wire 11, so that more wire 11 is drawn from the wire drum, and the wire end of the wire 11 is fed into the wire end clamping mechanism 5. The wire end clamping mechanism 5 clamps the wire end of the wire 11, and then the wire feeding mechanism 1 releases the wire 11 and withdraws. The wire feeding mechanism 1 and the wire tube 2 retreat to the initial position under the action of the mobile driving mechanism 3 to avoid the space above the magnetic ring 4;

[0048] Step S2: The hook needle 9 moves toward the direction of the magnetic ring 4, passes through the inner hole of the magnetic ring 4, and rotates a certain angle so that the hook on the hook needle 9 can hook the wire 11, and then the hook needle 9 moves down, hooks and drags the wire 11 to the other side of the magnetic ring 4. In this process, the wire feeding mechanism 1 continues to release the wire while maintaining a certain tension on the wire 11. Specifically, the hook needle 9 is connected to the lifting mechanism, and the lifting mechanism is connected to the rotating mechanism. Driven by the lifting mechanism, the hook needle 9 moves upward, passes through one of the wire-pulling holes 8.1 and the inner hole of the magnetic ring 4. When the height of the head of the hook needle 9 exceeds the wire 11, the rotating mechanism drives the hook needle 9 to rotate a certain angle such as 90°, so that the hook on the hook needle 9 can hook the wire 11, and then moves downward to hook the wire 11, that is, the wire 11 is hooked from the upper side of the magnetic ring 4 to the lower side of the magnetic ring 4; wherein the lifting mechanism can be a cylinder, and the rotating mechanism can be a motor.

[0049] Step S3: The hook 9 rotates 90° to change the arrangement direction of the wires 11 on both sides of the hook 9, so that the wires 11 on one side of the hook 9 are close to the wire hook 7 and enter the hooking range of the wire hook 7. Specifically, the hook 9 rotates 90°, and the two sections of wires 11 on both sides of the hook 9 are visually Figure 4 The left-right arrangement shown is changed to the front-back arrangement, that is, the wire 11 on one side of the hook needle 9 is close to the wire hook 7, so that the wire hook 7 can easily hook the wire 11;

[0050] Step S4: the wire reel 6 rotates a certain angle, the wire hook 7 hooks the wire 11 on the side of the hook needle 9 close to the wire hook 7, then the hook needle 9 moves upward for a distance to separate from the wire 11, then the hook needle 9 rotates in the opposite direction by a certain angle such as 90° and then moves downward, thereby releasing the wire 11, and the wire reel 6 continues to rotate, and the wire 11 released by the wire feeding mechanism 1 is wound around the wire reel 6; wherein, the wire reel 6 is a circular disc, which reduces the bending of the wire 11, and the rotation angle of the wire reel 6 determines the length of the wire 11 stored in the wire reel 6. Therefore, the rotation angle of the wire reel 6 can be adjusted according to the actual wire length required by the product.

[0051] Step S5: When the wire hook drum 6 rotates to the set angle, it means that the length of the wire 11 meets the winding length required by the magnetic ring 4, the wire feeding mechanism 1 clamps the wire 11, the wire end clamping mechanism 5 releases the wire end of the wire 11, the wire hook drum 6 continues to rotate, and the wire hook 7 completely pulls the tail end of the wire 11 from the inner hole of the magnetic ring 4 and the wire pulling hole 8.1, so that the end of the wire 11 with the wire end is completely wound around the outer periphery of the wire hook drum 6; Figure 7 As shown, at this time, there is only one wire 11 in the wire-pulling hole 8.1. The wire 11 passes through the hole in the middle of the magnetic ring 4 from above the magnetic ring 4, passes through the wire-pulling hole 8.1, and the tail of the wire is wound on the hook wire reel 6.

[0052] This enables the automatic winding of the winding machine.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
