Description

Technical Field

[0001] The invention relates to the technical field of coil production, and in particular to a winding machine for producing inductor coils. Background Art

[0002] An inductor is a toroidal coil wound around a ring-shaped frame such as a magnetic ring. It is widely used in various electronic devices such as the Internet, telecommunications, mobile devices, and household appliances. A toroidal winding machine is a mechatronic device for producing toroidal coils. According to the different winding methods, it can be divided into a hook winding machine, a fully automatic micro magnetic ring winding machine, and a semi-automatic toroidal winding machine. At present, the toroidal winding machines with a high degree of automation imported from abroad are expensive, and many of the parts are non-standard parts and customized parts. Once a fault occurs, the maintenance process is relatively complicated. Therefore, most of the toroidal winding machines on the domestic market are semi-automatic.

[0003] In the magnetic ring winding process of the inductor coil, the winding and hanging is a very critical step. The winding and hanging is to connect the free end of the metal wire to the magnetic ring. Before starting the winding process, the operator of the semi-automatic ring winding machine on the market connects the free end of the metal wire to the magnetic ring for the next winding process. The disadvantages of this method are obvious: first, the operator's familiarity directly affects the production efficiency of the coil product; second, in the continuous production process, due to the accumulation of working hours, the operator's fatigue will inevitably increase, which will also affect the production efficiency of the ring coil. At the same time, considering the improvement of the automation level of the entire ring winding machine production, it is necessary to design a mechanism to realize the automatic wire pulling, hanging and cutting process, replace the operator's manual operation part, and realize the full automation of the ring coil production. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a winding machine for producing inductor coils.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] like Figure 1-Figure 6 A winding machine for producing inductor coils, comprising a base 1, a workbench 3 slidably mounted on the base 1, a cylinder 2 fixedly connected to the base 1 to drive the workbench 3 to move on the base 1, a circular arc-shaped back plate 4 fixedly connected to the base 1, a circular arc-shaped winding tube 8 rotatably mounted on the back plate 4, a slot 301 is opened on the workbench 3 to accommodate the winding tube 8 passing through, a plurality of guide wheels 401 are rotatably mounted on the back plate 4 to guide the winding tube 8, and a first motor 402 is fixedly connected to the back plate 4. A friction wheel 403 is fixedly connected to the output shaft of the first motor 402 for driving the winding tube 8 to rotate. The winding tube 8 is provided with a winding shaft 801 for winding the metal wire. The winding tube 8 is provided with a clamping roller 802 for conveying the metal wire. A slide rail 9 is fixedly connected to the winding tube 8. A slider 10 is slidably fitted in the slide rail 9. A guide shaft 11 is rotatably installed on the slider 10 for guiding the metal wire. The slide rail 9 is provided with a first spring 21 to apply elastic force to the slider 10.

[0029] When the device winds the metal wire on the magnetic ring, the magnetic ring is placed on the notch 301 of the workbench 3, and then the cylinder 2 is started to drive the workbench 3 to move, so that part of the magnetic ring is located inside the winding tube 8, and the wire end of the metal wire on the winding shaft 801 passes through the pinch roller 802, and is fixed on the magnetic ring after being guided by the guide shaft 11. Then the first motor 402 is started, and the first motor 402 drives the friction wheel 403 to rotate. The rotation of the friction wheel 403 drives the winding tube 8 to make a circular motion around the tangent of the magnetic ring, thereby winding the metal wire on the magnetic ring.

[0030] like Figure 3-Figure 4 and Figure 7-Figure 8As shown, a driving structure is provided on the workbench 3 for driving the magnetic ring to rotate, and the driving structure includes a second motor 12, and the second motor 12 is fixedly connected to the workbench 3. A driving roller 13 is coaxially fixedly connected to the output shaft of the second motor 12, and two slide grooves 302 are provided on the workbench 3. A sliding member 15 is slidably matched in the slide groove 302, and a driven roller 16 is rotatably installed on the sliding member 15. A second spring 14 is provided in the slide groove 302 to apply elastic force to the sliding member 15.

[0031] When the magnetic ring is placed on the workbench 3, the outer ring of the magnetic ring is pressed against the driving roller 13, and the two driven rollers 16 are pressed against the inner ring of the magnetic ring under the elastic force of the second spring 14. When the second motor 12 drives the driving roller 13 to rotate, the driving roller 13 drives the magnetic ring to rotate around its own axis under the action of friction, so that the winding tube 8 performs a scanning motion around the magnetic ring to wind the metal wire around the entire magnetic ring.

[0032] like Figure 3-Figure 4 A bracket 5 is fixedly connected to the base 1, an electric cylinder 6 is fixedly connected to the bracket 5, a pressure block 7 is fixedly connected to the output end of the electric cylinder 6, and the pressure block 7 can pass through the slot 301. The electric cylinder 6 is used to drive the pressure block 7 to make a linear motion along the axial direction of the magnetic ring and make the pressure block 7 pass through the slot 301.

[0033] like Figure 9-10 As shown, a knife holder 17 is fixedly connected to the base 1 , a blade 18 is fixedly connected to the knife holder 17 for cutting metal wires, a third spring 20 is fixedly connected to the knife holder 17 , and a top block 19 is fixedly connected to the third spring 20 .

[0034] When the pressing block 7 passes through the notch 301, it can press the metal wire into the bottom of the notch 301, so that the metal wire contacts the top block 19. When the pressing block 7 continues to apply pressure to the metal wire, the top block 19 will move downward and compress the third spring 20. The downward movement of the top block 19 will cause the blade 18 to contact the metal wire. As the pressing block 7 continues to apply pressure, the blade 18 will cut the metal wire.

[0035] The working principle and workflow are as follows:

[0036] S1: The magnetic ring is clamped between the driving roller 13 and the driven roller 16. Under the elastic force of the second spring 14, the driving roller 13 abuts against the outer wall of the magnetic ring.

[0037] S2: Start the cylinder 2, which drives the workbench 3 to translate so that part of the magnetic ring is located inside the winding tube 8;

[0038] S3: Start the first motor 402 and the second motor 12, wherein:

[0039] After the first motor 402 is started, it drives the friction wheel 403 to rotate. The rotation of the friction wheel 403 drives the winding tube 8 to make a circular motion around the tangent of the magnetic ring, thereby winding the metal wire around the magnetic ring;

[0040] After the second motor 12 is started, it drives the driving roller 13 to rotate. Under the action of friction, the driving roller 13 drives the magnetic ring to rotate around its own axis, so that the winding tube 8 performs a scanning motion around the magnetic ring to wind the metal wire around the entire magnetic ring. After the magnetic ring winding is completed, an inductor coil is obtained.

[0041] S4: Fig.11 As shown, after the magnetic winding is completed, the pinch roller 802 stops rotating, the cylinder 2 is started, and the cylinder 2 drives the workbench 3 to translate, so that the inductor coil on the workbench 3 is away from the winding tube 8.

[0042] S5: Fig.12 As shown, after the inductor coil is away from the winding tube 8, the electric cylinder 6 is started, and the electric cylinder 6 drives the pressure block 7 to move downward. During the downward movement of the pressure block 7, the metal wire will be pressed into the bottom of the slot 301, so that the metal wire is in contact with the top block 19. When the electric cylinder 6 drives the pressure block 7 to continue to apply pressure to the metal wire, the metal wire is bent by the pressure block 7 and the top block 19 moves downward and compresses the third spring 20. The downward movement of the top block 19 will make the blade 18 contact with the metal wire. As the electric cylinder 6 drives the pressure block 7 to continue to apply pressure, the blade 18 will cut the metal wire, so that the metal wire is disconnected from the inductor coil.

[0043] S6: Fig.13 As shown, after the metal wire is disconnected, the electric cylinder 6 is on standby and the pressing block 7 stops moving downward. At this time, the finished inductor coil is taken out from the driving roller 13 and the driven roller 16, and a new magnetic ring is placed between the driving roller 13 and the driven roller 16.

[0044] S7: In the above steps S4-S6, the first spring 21 applies an oblique upward pulling force to the metal wire through the guide shaft 11, so that the metal wire remains tensioned, and the bending part of the metal wire is also hooked on the pressing block 7, so that the bending part of the metal wire is continuously locked on the pressing block 7.

[0045] S8: Fig.14 As shown, the cylinder 2 is started, and the cylinder 2 drives the workbench 3 to move horizontally, so that the new magnetic ring on the workbench 3 approaches the pressure block 7. When the new magnetic ring moves near the pressure block 7, the electric cylinder 6 drives the pressure block 7 to move upward, and the pressure block 7 drives the bending part of the metal wire to move upward. When the pressure block 7 moves up to above the slot 301, the bending part of the metal wire will hook on the new magnetic ring.

[0046] S9: After the pressing block 7 is reset, the cylinder 2 drives the workbench 3 to translate, so that the new magnetic ring enters the winding tube 8 and then performs the winding work.

[0047] Compared with the prior art, the device moves the metal wire to above the blade 18 by means of the workbench 3 being translated on the base 1, and then uses the electric cylinder 6 to drive the pressing block 7 to move linearly to cut and bend the metal wire, and uses the elastic force of the first spring 21 to keep the metal wire taut while locking the free end of the metal wire on the pressing block 7, and finally drives the pressing block 7 by means of the electric cylinder 6 to make the free end of the metal wire hook on the magnetic ring, thereby achieving the purpose of locking the free end of the metal wire on the magnetic ring.

[0048] The winding machine provided by the present invention drives the workbench 3 to move horizontally by the cylinder 2 and drives the pressing block 7 to move vertically by the electric cylinder 6 to cut, bend and lock the metal wire, so that the free end of the cut metal wire can be connected to the magnetic ring, and the operator does not need to perform the work of winding and hanging the wire, thereby reducing the labor intensity of the operator and improving the degree of automation of the winding machine.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
