Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic ring winding technology, specifically to a winding device for a winding machine. Background Technology
[0002] Cross-wound (or butterfly-wound) inductors, due to their unique wiring method, require starting the winding from the middle of the entire wire, winding half of the wire, and then starting the winding of the remaining half.
[0003] Currently, most winding machines for this type of coil on the market use a coaxial wire feeding method before winding, with the wire fed into the magnetic ring center. This method relies on the rolling of two rubber rollers to feed the wire downwards. The length of the wire fed out is determined by the rotation angle of the rubber rollers controlled by a servo motor. See [link to relevant documentation]. Figure 11 As shown. This method has the following disadvantages:
[0004] The wire feeding mechanism occupies the space above the magnetic ring, which greatly restricts the design of the winding and wire laying mechanism; the wire feeding length is not accurate enough, and 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 product's wire length is relatively long, the end of the wire will become uncontrollable, often resulting in wire deformation, bending, and other problems. This can cause the wire to get tangled in other mechanisms, leading to issues such as wire knots, breakage, and damage to the insulation layer. Utility Model Content
[0006] This utility model addresses the existing technical problems by providing a winding device for a winding machine.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wire feeding device for a winding machine includes a wire feeding mechanism, a wire end clamping mechanism, a hooking reel, and a hook needle. The wire feeding mechanism is used to feed the wire end to the wire end clamping mechanism. The wire end clamping mechanism is used to clamp or release the wire end. The hook needle is used to pass through the inner hole of a magnetic ring to hook the wire to the other side of the magnetic ring. The hooking reel is provided with a hook, which is used to hook the wire between the magnetic ring and the hook needle. The hooking reel is mounted on a rotary drive device. The hooking reel rotates under the action of the rotary drive device and winds the end of the wire with the wire end onto the hooking reel.
[0008] Based on the above technical solution, the present invention can be further improved as follows:
[0009] Preferably, the wire feeding mechanism is mounted on a moving drive mechanism, and a wire tube is installed on the moving drive mechanism. The wire feeding mechanism feeds the wire end to the wire end clamping mechanism through the wire tube.
[0010] Preferably, the hook has a groove opening.
[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 thread guide, which is rotatably configured and has a plurality of thread guide holes circumferentially arranged, the thread guide holes being located between the hook and the magnetic ring.
[0014] Preferably, the device further includes a clamping mechanism for clamping the magnetic ring.
[0015] The beneficial effects of this utility model are as follows: the wire feeding mechanism feeds the wire to the wire end clamping mechanism, and the wire is hooked by the hook. The wire feeding mechanism can move back and forth under the drive of the moving drive mechanism, without occupying the space above the magnetic ring, ensuring that the winding and wire laying mechanism has sufficient installation space and reducing the design difficulty; by winding the wire with the wire end on the hook reel, the rotation angle of the hook reel can be set according to the wire length, so as to achieve precise control of the wire length and ensure that the wound coil meets the design requirements; since the wire end is wound on the hook reel, and a protective cover can be set on the outside of the hook reel, it can be ensured that the wire is always stored in the wire holding space between the hook reel and the protective cover, the wire end position is controllable, and the wire is prevented from winding into other equipment, solving the problems of wire knotting, breakage or damage to the insulation layer.
[0016] Meanwhile, the outer circumference of the hook reel is 3.14 times its diameter. Winding the wire around the hook reel can significantly reduce the size of the wire storage mechanism. The hooks on the hook reel are smooth and the groove openings have a large bending radius, which can significantly reduce the bending degree when the wire is wound around, avoid large-angle bending of the wire, ensure that the outer insulation layer of the wire is not damaged, and also ensure the flatness of the wire and prevent the wire from deforming.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

The terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship 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; therefore, they should not be construed as limitations on this utility model.
[0031] Reference Figures 1 to 10As shown, this utility model discloses a wire feeding device for a winding machine, including a wire feeding mechanism 1, a wire end clamping mechanism 5, a hooking disc 6, and a hook 9. The wire feeding mechanism 1 is used to feed the wire end of the wire 11 to the wire end clamping mechanism 5. In this embodiment, the wire 11 is copper wire. The wire end clamping mechanism 5 is used to clamp or release the wire end of the wire 11. The hook 9 is used to pass through the inner hole of the magnetic ring 4 to hook the wire 11 to the other side of the magnetic ring 4. In this embodiment, the hook 9 hooks the wire 11 above the magnetic ring 4. The wire 11 is hooked below the magnetic ring 4. A hook 7 is provided on the outer circumference of the hook reel 6. The hook 7 is used to hook the wire 11 between the magnetic ring 4 and the hook needle 9. The hook reel 6 is mounted on the rotary drive device 12. Under the action of the rotary drive device 12, the hook reel 6 rotates and winds the end of the wire 11 with the lead wire onto the hook reel 6. The lead wire clamping mechanism 5 is mounted on the frame (not shown in the figure). The lead wire clamping mechanism 5 includes lead wire clamping claws for gripping the lead wire of the wire 11. The magnetic ring 4 is a circular or rectangular magnetic ring.
[0032] In an optional embodiment, the wire 11 can also be a copper-clad aluminum wire or an aluminum wire, etc. The wire is wound onto a ring by the winding device to meet the usage requirements in different environments and improve the applicability.
[0033] In this embodiment, specifically, the wire feeding mechanism 1 is mounted on the moving drive mechanism 3, and the moving drive mechanism 3 is equipped with a wire guide tube 2. The wire feeding mechanism 1 feeds the wire end of the wire 11 to the wire end clamping mechanism 5 through the wire guide tube 2. The moving drive mechanism 3 is an external slide rail cylinder. The wire feeding mechanism 1 and the wire guide tube 2 are both mounted 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 guide tube 2 to move synchronously. The end of the moving drive 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 guide tube 2 is mounted on the moving drive mechanism 3 through a fixing block. The fixing block is mounted on the moving drive mechanism 3 through a vertically set elongated hole. Therefore, the height of the fixing block and the wire guide tube 2 can be adjusted, improving the convenience of use. The wire guide tube 2 plays a role in supporting, positioning and leveling the wire 11, making it convenient for the wire end clamping mechanism 5 to clamp the wire end of the wire 11 and move the wire 11 along the wire guide tube 2, reducing the occurrence of bending and knotting of the wire 11.
[0034] In this embodiment, specifically, the hook 7 has a groove opening, which is U-shaped, V-shaped, or arc-shaped. A roller 13 is provided at the bottom of the groove opening. Alternatively, the hook 7 may be made entirely of Teflon. The purpose is to reduce the friction between the hook 7 and the line 11. The direction of the groove opening is the same as the rotation direction of the hook reel 6. The roller 13 can reduce the wear of the hook 7 on the line 11, reduce the damage to the line 11, and ensure the smooth movement of the line 11 along the hook 7.
[0035] The winding machine's winding device also includes a wire guide plate 8, which is rotatable. The wire guide plate 8 has multiple wire guide holes 8.1 evenly arranged around its circumference, and the wire guide holes 8.1 are located between the hook needle 9 and the magnetic ring 4. The hook 9 passes through the thread-pulling hole 8.1 and the inner hole of the magnetic ring 4, hooking the thread 11. The hook 7 picks up the thread 11 on one side of the hook 9 and continues to rotate it. At this time, the hook 9 moves upward a certain distance and separates from the thread 11. Then, the hook 9 rotates in the opposite direction at a certain angle, such as 90°, and then moves downward, thereby releasing the thread 11. The thread feeding mechanism 1 continues to feed the thread while maintaining a certain tension on the thread 11, so that the thread 11 is wound around the hook reel 6. When the hook reel 6 rotates to a set angle, it means that a sufficient length of thread 11 has been wound around the hook reel 6. Then, the thread feeding device 1 clamps the thread 11 and stops feeding the thread. The thread end clamping mechanism 5 releases the thread end, and the hook reel 6 continues to rotate, so that the thread end of the thread 11 completely passes through the thread-pulling hole 8.1 and is wound around the hook reel 6. This completes the automatic thread loading. The wire hole 8.1 restricts the range of movement of the wire 11 in the horizontal direction, which can ensure that when the wire hook 7 carries the wire 11 for winding, the wire 11 will not tilt too much relative to the magnetic ring 4.
[0036] The thread-picking disc 8 rotates under the drive of a drive device such as a drive motor, rotating another thread-picking hole 8.1 to below the magnetic ring 4. The hook 9 and the line hook 7 repeat the above action, hooking the line 11 in different thread-picking holes 8.1, which serves to separate the line 11 and prevent long lines 11 from getting tangled together, thus improving the smoothness of subsequent operations on the line 11.
[0037] The winding machine's winding 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 gripper. The clamping mechanism 10 is mounted on the frame. The clamping cylinder drives the gripper to clamp the magnetic ring 4, facilitating the winding of the magnetic ring 4.
[0038] The usage process of this utility model is as follows:
[0039] Step S1: The wire feeding mechanism 1 feeds the wire end of the wire 11 to the wire end clamping mechanism 5, which clamps the wire end of the wire 11. Specifically, the wire 11 drawn from the spool passes through the wire feeding mechanism 1 and the wire tube 2, with a section of wire end protruding outside the wire tube 2. The wire feeding mechanism 1 clamps the wire 11, and the moving drive mechanism 3 drives the wire feeding mechanism 1 and the wire tube 2 to move towards the wire end clamping mechanism 5 until they are above the magnetic ring 4. During the movement, the wire 11 is dragged, allowing more wire 11 to be drawn from the spool. The wire end of the wire 11 is fed into the wire end clamping mechanism 5, which clamps the wire end of the wire 11. Then, the wire feeding mechanism 1 releases the wire 11 and retracts. The wire feeding mechanism 1 and the wire tube 2 return to their initial positions under the action of the moving drive mechanism 3 to avoid the space above the magnetic ring 4.
[0040] Step S2: The hook 9 moves towards the magnetic ring 4 and passes through the inner hole of the magnetic ring 4. It rotates at a certain angle so that the hook on the hook 9 can hook the line 11. Then the hook 9 moves down, hooking and dragging the line 11 to the other side of the magnetic ring 4. During this process, the line feeding mechanism 1 continues to feed the line while maintaining a certain tension on the line 11. Specifically, the hook 9 is connected to the lifting mechanism, and the lifting mechanism is connected to the rotating mechanism. Driven by the lifting mechanism, the hook 9 moves upward, passing through one of the line-pulling holes 8.1 and the inner hole of the magnetic ring 4. When the height of the head of the hook 9 exceeds the line 11, the rotating mechanism drives the hook 9 to rotate at a certain angle, such as 90°, so that the hook on the hook 9 can hook the line 11. Then it moves downward, hooking the line 11 down, that is, hooking the line 11 from the upper side of the magnetic ring 4 to the lower side of the magnetic ring 4. The lifting mechanism can be a cylinder, and the rotating mechanism can be a motor.
[0041] Step S3: Rotate the crochet hook 9 by 90° to change the arrangement direction of the yarn 11 on both sides of the crochet hook 9, so that the yarn 11 on one side of the crochet hook 9 is closer to the hook 7 and enters the hooking range of the hook 7. Specifically, rotating the crochet hook 9 by 90° changes the arrangement direction of the two sections of yarn 11 on both sides of the crochet hook 9 from the view Figure 4 The left-right arrangement shown is changed to a front-back arrangement, so that even if the yarn 11 on one side of the crochet hook 9 is close to the hook 7, it is convenient for the hook 7 to hook the yarn 11.
[0042] Step S4: The hook reel 6 rotates at a certain angle, and the hook 7 hooks the line 11 near the hook 9. Then, the hook 9 moves upward a certain distance to separate from the line 11. Next, the hook 9 rotates in the opposite direction at a certain angle, such as 90°, and then moves downward to release the line 11. The hook reel 6 continues to rotate, winding the line 11 released by the line feeding mechanism 1 onto the hook reel 6. The hook reel 6 is a disc, which reduces the bending of the line 11. The angle of rotation of the hook reel 6 determines the length of the line 11 stored in the hook reel 6. Therefore, the angle of rotation of the hook reel 6 can be adjusted according to the actual line length required by the product.
[0043] Step S5: When the hook disc 6 rotates to the set angle, it indicates 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 hook disc 6 continues to rotate, and the 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 wrapped around the outer circumference of the hook disc 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, passes through the wire-pulling hole 8.1, and the end of the wire is wrapped around the hook reel 6.
[0044] This enabled the automatic loading of the winding machine.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
