Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic winding machine. Background Art
[0002] In the power electronics industry, toroidal inductors are often needed to realize their circuit functions. The preparation of toroidal inductors usually uses wires with specified parameters and is wound on a specified toroidal core in a specified winding method. Toroidal inductors used in ordinary power electronics industries usually have a small ring diameter. In the prior art, hook-wire winding machines are usually used to achieve automatic winding.
[0003] When a hook-wire winding machine performs automatic winding operations on an annular magnetic core, it is generally necessary to hook the wire with a wire hook, pull the wire to pass it all through the magnetic core, and then fold it again, repeating the process of hooking the wire-folding-hooking the wire-folding, and finally winding the wire onto the annular magnetic core to complete the winding and obtain a toroidal inductor.
[0004] When the hook-wire winding machine is performing a specific automatic winding operation, the biggest problem it faces is how to organize the wire harness. For a winding operation process with a large number of coils and a long total length of wire, the hook-wire winding machine provided in the prior art is often designed with a winding machine height corresponding to the wire length, leaving a sufficiently long hooking distance for the hook wire hook, so that when the hook wire hook hooks and drags the wire, all the unwound wires can be pulled by the hook wire hook and all pass through the center of the annular magnetic core. This simple method of increasing the height of the equipment and extending the hooking distance of the wire hook to complete the winding operation of longer wires will, on the one hand, increase the size of the equipment, which is not conducive to the operation and maintenance of technical personnel. On the other hand, it also greatly limits the processing range of the equipment. Once the equipment is manufactured and the hooking distance of the wire hook is determined, the maximum winding length of the equipment is limited to the maximum hooking distance of the wire hook. For wires with longer lengths, the wire hook cannot pull the entire wire through the annular core in a single hooking process. Repeated hooking-folding-hooking-folding operations can easily cause the wires to be entangled with each other. After the wire is folded many times, the center of the annular core is blocked, and the winding operation cannot continue. Utility Model Content

[0037] Please refer to Figure 1-3 In this specific embodiment, an automatic winding machine for winding a toroidal inductor is provided, including a workbench 1, on which two processing stations are arranged, and the two processing stations work independently. The automatic winding machine can independently perform winding operations on two toroidal magnetic cores LL at the same time. The following description focuses on one processing station.
[0038] The automatic winding machine also includes a wire hooking assembly 2, a wire arranging assembly 3, and a wire lifting assembly 4;
[0039] The wire hooking assembly 2 is disposed below the workbench 1 and is used to hook the wire M above the annular magnetic core LL, pass it through the annular magnetic core LL and pull it to the bottom of the workbench 1;
[0040] The wire management component 3 is arranged on one side of the wire hook component 2, and is used to pull all the wires M to the bottom of the workbench 1 and bundle them neatly;
[0041] The wire lifting assembly 4 is disposed on the workbench 1 , and is used to lift the wire M below the workbench 1 and fold it over the annular magnetic core LL.
[0042] After the annular magnetic core LL is placed on the workbench 1, the wire M is placed above the annular magnetic core LL, and the wire hooking assembly 2 extends from the center of the annular magnetic core to hook the wire M above the annular magnetic core LL. After the wire M is hooked by the wire hooking assembly 2, it moves down to the bottom of the workbench 1 together with the wire hooking assembly 2. At this time, the wire M is further pulled, and the wire management assembly 3 pulls the wire M out of the hooking wire 2 and neatly gathers it at the wire management assembly 3 below the workbench 1. The wire lifting assembly 4 then lifts the wire M below the workbench 1 and folds it above the annular magnetic core LL so that the wire hooking assembly 2 can hook the wire next time. With the cooperation of the wire hooking assembly 2, the wire management assembly 3 and the wire lifting assembly 4, the winding machine can repeat the process of hooking-managing-lifting-hooking-managing-lifting, and wind the wire M around the annular magnetic core LL one circle at a time. Since the wire management component 3 is provided, even if the length of the wire M is longer than the single hooking distance of the wire hooking component 2, the wire management component 3 can assist the wire hooking component 2 to pull all the wires M through the annular magnetic core LL and bundle them neatly. In this way, not only can the wire M be conveniently and neatly coiled around the annular magnetic core LL in a single-strand manner, but the winding machine as a whole can also ensure the normal execution of the winding operation without significantly increasing the volume of the device to extend the single hooking distance of the wire hooking component 2.
[0043] Please refer to Figure 1-4 . In this specific embodiment, a core alignment hole 11 and a wire lifting groove 12 are provided on the workbench 1, and the core alignment hole 11 is connected with the wire lifting groove 12; the annular magnetic core LL keeps the center of the ring aligned with the core alignment hole 11, and the hole center is placed above the core alignment hole 11, the wire hook assembly 2 is arranged below the core alignment hole 11, and the wire lifting assembly 4 is arranged on the workbench, and is located on one side of the wire lifting groove 12. The core alignment hole 11 provided on the workbench will serve as a positioning anchor point to help the annular magnetic core LL and the wire hook assembly 2 determine their own positions, while the wire lifting groove 12 leaves working space for the wire lifting assembly 4, so that the wire lifting assembly 4 can lift the wire and fold it over the annular magnetic core LL.
[0044] Please refer to Figure 1-3, 5-7. In this specific embodiment, it also includes a wire feeding assembly 5, which is used to feed the required wire M to the top of the annular magnetic core LL; the wire feeding assembly 5 includes a wire storage disk 51, a wire feeding guide 52, a wire cutting knife 53, a wire end clamp 54 and a clamp telescopic cylinder 55; the wire storage disk 51 is used to store the wire M to be processed, and the unprocessed wire M is wound on the wire storage disk 51 in batches; the wire feeding guide 52 is used to feed the wire M from the wire storage disk 51 to the top of the annular magnetic core LL, and the wire feeding guide 52 has a wire inlet 52A and a wire outlet 52B, and the wire inlet 52A and the wire outlet 52B of the wire feeding guide 52 are connected to form a wire M feeding channel; the wire cutting knife 53 is used to cut the wire M. Wire M, the wire cutter 53 is arranged on the workbench 1, and the wire cutter 53 is erected at the wire outlet 52B of the wire feeding guide tube 52; the cylinder body of the clamping jaw telescopic cylinder 54 is arranged on the workbench 1, and the clamping jaw telescopic cylinder 54 is arranged on the side of the placement position of the annular magnetic core LL away from the wire feeding guide tube 52, and the thread end clamping jaw 55 is fixed on the cylinder output shaft of the clamping jaw telescopic cylinder 54; the cylinder output shaft of the clamping jaw telescopic cylinder 54 can be extended and retracted between the cylinder body of the clamping jaw telescopic cylinder 54 and the wire outlet 52B of the wire feeding guide tube 52, so as to drive the thread end clamping jaw 55 to cross the annular magnetic core LL and extend to the wire outlet 52B of the wire feeding guide tube 52, or drive the thread end clamping jaw 55 to retract to the cylinder body of the clamping jaw telescopic cylinder 54. The wire cutter 53 is used to drop and cut the wire M at a specified time. The wire cutter 53 is set on the workbench 1, and the wire cutter 53 is erected at the wire outlet 52B of the wire feeding guide 52. Since different toroidal inductors have different inductive reactance values, and the inductive reactance of the toroidal inductor is directly related to the length of the wire M wound on the toroidal magnetic core LL, when manufacturing toroidal inductors with different inductive reactances, the required length of the wire M will also be different. The wire M is transported by the wire feeding guide 52, and the wire cutter 53 is controlled to cut the wire M at an appropriate time point, so that the wire M of the corresponding length that meets the inductive reactance requirements of the toroidal inductor processed this time can be obtained. A clamping jaw retracting cylinder and a wire end clamping jaw are provided, and the two work in coordination. The clamping jaw retracting cylinder 54 and the wire feeding guide cylinder 52 are respectively provided on both sides of the annular magnetic core LL. When the wire M is fed out from the wire outlet 52B of the wire feeding guide cylinder 52, the clamping jaw retracting cylinder 54 extends, and the wire end clamping jaw 55 is extended to the wire outlet 52B of the wire feeding guide cylinder 52, and the wire end clamping jaw 55 clamps the end of the wire M. At this time, the clamping jaw retracting cylinder 54 retracts, driving the wire end clamping jaw 55 to retract. In this way, the wire M is pulled by the wire end clamping jaw 55 to straddle the top of the annular magnetic core LL, waiting to be hooked by the wire hooking assembly 2.
[0045] See also Figure 1-8In this specific embodiment, the wire hook assembly 2 includes a wire hook driver 21 and a wire hook 22; the wire hook driver 21 is aligned with the magnetic core alignment hole 11 and is arranged below the workbench 1, and the wire hook 22 is arranged on the power output shaft of the wire hook driver 21, and the power output shaft of the wire hook driver 21 can be extended and retracted along the vertical direction of the magnetic core alignment hole 11 to drive the wire hook 22 to extend or retract from the annular magnetic core LL. As described above, the wire M is pulled by the wire head clamp 55 and straddles the top of the annular magnetic core LL. Since the cylinder output shaft of the wire hook driver 21 is extended and retracted in the vertical direction of the magnetic core alignment hole 11, and the wire hook 22 is arranged on the power output shaft of the wire hook driver 21, after the annular magnetic core LL is aligned with the hole center of the magnetic core alignment hole 11 and placed on the workbench 1, the wire hook driver 21 will drive the wire hook 22 to extend or retract from the annular magnetic core LL along the vertical direction. When the wire hook 22 goes up vertically and extends out of the annular magnetic core LL, the wire M straddling the annular magnetic core LL is pushed open; when the wire hook 22 goes down vertically and retracts from the annular magnetic core LL, the wire M will be hooked by the wire hook 22. At this time, since the wire end clamp 55 grasps the end of the wire M, the wire M is pulled out of the wire guide 52 continuously by the wire hook 22, and the wire M originally straddling the annular magnetic core LL is pulled to the bottom of the workbench 1 by the wire hook 22. When the wire hook driver 21 is implemented, a motor or a cylinder with suitable parameters can be selected and applied therein.
[0046] See also Figure 1-9After the wire M originally straddling the annular magnetic core LL is pulled to the bottom of the workbench 1 by the wire hook 22, since the end of the wire M is grasped by the wire end clamp 55, it is not difficult to infer that at this time, there are wire segments of the wire M on both sides of the wire hook 22, that is, a continuous and complete wire M is hooked by the wire hook 22 and bent into two segments, and pulled together to the bottom of the workbench 1. In this case, if the wire M is not gathered and neatly arranged, when the wire M is subsequently lifted, the two segments of the wire will be folded to the top of the annular magnetic core LL at the same time. The next time the wire hook 22 hooks the wire above the annular magnetic core LL again, it needs to hook the two segments of the wire M at the same time, and the number of segments of the folded wire M will become 4 segments... In this cycle, the number of segments of the wire M will increase exponentially, and the winding operation will be difficult to continue. The wires M will soon be entangled with each other and blocked at the center of the annular magnetic core LL, and the entire winding operation cannot be completed normally. Based on the above problems, in the present specific embodiment, the wire management component 3 includes a wire management drum 31, a wire lead rotating hook 32, a wire management device 33, a wire management base 34, a wire management shaft 35, a wire punching motor 36 and a wire punching head 37; the wire management drum 31 is arranged near the wire hook driver 21, and the wire lead rotating hook 32 is arranged on the top of the wire management drum 31, and the wire lead rotating hook 32 can rotate around the axis of the wire management drum 31 to hook the wire M pulled by the hook assembly 2 to the bottom of the workbench 1; the wire management device 33 is arranged between the wire management drum 31 and the wire lead rotating hook 32, and the wire management device 33 is fixedly connected to the wire lead rotating hook 32; the wire management device 33 has a wire inlet 33A and a wire outlet 33B, and the wire inlet 33A of the wire management device 33 and its wire outlet 33B are connected to form a guide wire M from the lead The wire rotating hook 32 is bent and close to the channel of the tube surface of the wire management drum 31; the wire management base 34 is arranged near the wire hook driver 21; the wire management shaft 35 is arranged on the wire management base 34, and the bottom of the wire management shaft 35 is connected to the wire management base 34, the wire management drum 31 keeps the axis overlapping with the wire management shaft 35, and the wire management drum 31 is sleeved on the wire management shaft 35, and the wire management shaft 35 can rotate around its own axis relative to the wire management drum 31; the lead wire rotating hook 32 and the wire organizer 33 are fixedly connected to the wire management shaft 35; the wire bonding motor 36 is arranged on the wire management base 34, and the wire bonding head 37 is fixed on the motor output shaft of the wire bonding motor 36, and the motor output shaft of the wire bonding motor 36 rotates periodically to drive the wire bonding head 37 to swing periodically to disengage the wire M from the wire hook 22.
[0047] See also Figure 1-9The lead wire rotating hook 32 is driven by the wire management shaft 35 to rotate periodically. As mentioned above, the wire M originally straddling the annular magnetic core LL is pulled to the bottom of the workbench 1 by the wire hook 22. The lead wire rotating hook 32 rotates to the vicinity of the wire M and hooks one of the wire sections M on one side of the wire hook 22, which drives the hooked wire section M to be pulled out from the wire hook 22. The pulled out wire M is guided by the wire receiver 33 and continuously passes through the wire manager 33, and is bent along the wire inlet 33A of the wire manager 33 to its wire outlet 33B. After hooking a section of the wire M, the lead wire rotating hook 32 continues to rotate, and the wire M hanging on the lead wire rotating hook 22 becomes longer and longer, and is coiled one circle at a time from the wire outlet 33B of the wire manager 33 to the surface of the wire management barrel 31. During this process, the wire M is pulled and continuously drawn out from the wire storage disk 51 through the wire feeding guide cylinder 52 and close to the inner wall of the annular magnetic core LL. When the length of the wire M meets the requirements of this winding operation, the wire cutter 53 falls and cuts the wire M, and the lead rotating hook 32 continues to rotate until all the unwound parts of the wire M are pulled to the bottom of the workbench 1 and are wound onto the surface of the wire management cylinder 31 to be neatly gathered. After all the wire M sections are gathered onto the surface of the wire management cylinder 31, the motor output shaft of the wire bonding motor 36 swings, driving the wire bonding head 37 to swing, and the other section of the wire M still hanging on the wire hook 22 is knocked down, and the wire M is separated from the wire hook 22, so that the wire hook 22 is ready to go up and perform the next wire hooking action.
[0048] See also Figure 1-9 . Following the operation of the above-mentioned wire hooking assembly 42 and the wire organizing assembly 43, the wire M is now in a state where the end is tightly clamped by the wire end clamp 55, and the unwound portion of the wire M is wound on the surface of the wire organizing barrel 31, in order to continue to wind the wire M onto the annular magnetic core LL. In this specific embodiment, the wire lifting assembly 4 includes a wire lifting manipulator 41 and a wire lifting wheel 42; the wire lifting manipulator 41 is disposed on a workbench and is located on the side of the wire lifting groove 12 away from the magnetic core alignment hole 11; the top end of the wire lifting manipulator 41 extends out to support and fold the wire M; the wire lifting wheel 42 is sleeved on the top end of the wire lifting manipulator 41, and the wire lifting wheel 42 is fixedly connected to the wire lifting manipulator 41. The front end of the wire lifting manipulator 41 can extend toward the direction of the wire M, avoid the wire M and go around to one side of the wire M to hold the wire M. At this time, the wire M is attached to the circumferential surface of the wire lifting wheel 42. The wire lifting manipulator 41 drives the wire lifting wheel 42 to lift the wire M and fold it over the annular magnetic core LL.
[0049] See also Figure 1-3 , Figure 5-7In this specific embodiment, at least two core synchronizers 6 are also included, each of which is arranged on the workbench 1, and each of which is arranged around the annular core LL placed above the core alignment hole 11; each of the core synchronizers 6 includes at least one core synchronous motor 61, a plurality of core synchronous wheels 62 and a core synchronous belt 63; the core synchronous motor 61 is arranged on the workbench 1; the core synchronous wheels 62 are arranged on the workbench 1, and each of the core synchronous wheels 62 can rotate around its own axis, and each of the core synchronous wheels 62 maintains Its axis is perpendicular to the plane where the workbench 1 is located. At least one magnetic core synchronous wheel 62 is connected to the motor output shaft of the magnetic core synchronous motor 61. The magnetic core synchronous belt 63 is coated on the wheel circumference of the magnetic core synchronous wheel 62 of the same group, and the belt surface of the magnetic core synchronous belt 63 is also in contact with the annular magnetic core LL placed above the magnetic core alignment hole 11. When the magnetic core synchronous motor 61 outputs torque, the magnetic core synchronous wheel 62 connected thereto rotates, and the magnetic core synchronous belt 63 coated on the wheel circumference of the magnetic core synchronous wheel 62 rotates accordingly, driving the annular magnetic core LL in contact with the belt surface of the magnetic core synchronous belt 63 to rotate. The magnetic core synchronizer 6 is used to contact the annular magnetic core LL to drive the annular magnetic core LL to rotate around its own axis, so that the wire M is wound around the annular magnetic core LL in circles to finally obtain an annular inductance.
[0050] See also Figure 1-4In this specific embodiment, it also includes a loading and unloading assembly 7, which includes a loading and unloading motor 71, a loading and unloading cylinder 72, and a loading and unloading clamp 73; the loading and unloading motor 71 is a linear motor, and its motor track is laid above the workbench 1 in a direction parallel to the workbench 1. The motor output slider of the loading and unloading motor 71 can reciprocate along its motor track, and the cylinder body of the loading and unloading cylinder 72 is arranged on the motor output slider of the loading and unloading motor 71, and its cylinder output shaft extends downward perpendicular to the plane where the workbench 1 is located, and the loading and unloading clamp 73 is arranged on the cylinder output shaft of the loading and unloading cylinder 72. When loading, the motor output slider of the loading and unloading motor 71 slides to the storage place of the annular magnetic core LL, the cylinder output shaft of the loading and unloading cylinder 72 extends, and the loading and unloading clamp 73 contacts and grabs the annular magnetic core LL. After the loading and unloading clamp 73 grabs the annular magnetic core LL, the cylinder output shaft of the loading and unloading cylinder 72 retracts. At this time, the output slider of the loading and unloading motor 71 slides along its motor track to the top of the magnetic core alignment hole 11, and the cylinder output shaft of the loading and unloading cylinder 72 extends again, placing the annular magnetic core LL above the magnetic core alignment hole 11, ensuring that at least one magnetic core synchronous belt 63 is in contact with the outer ring surface of the annular magnetic core LL, and then the loading and unloading clamp 73 releases the annular magnetic core LL. After the annular magnetic core LL is wound and becomes a complete annular inductor, the loading and unloading assembly 7 takes away the annular inductor according to the same principle. The loading and unloading assembly 7 can conveniently grab the toroidal magnetic core LL waiting for loading and place it on the workbench 1, or take away the wound toroidal inductor from the workbench 1, so as to help the winding machine realize full-automatic winding without manual intervention.
