Description

Technical Field

[0001] The utility model relates to the technical field of transformer iron core production, in particular to an amorphous three-dimensional iron core tape winding machine. Background Art

[0002] The amorphous three-dimensional wound core includes three single frames with the same structure. The three core columns formed by the assembly of the three single frames are arranged in an equilateral triangle in three dimensions. Each single frame is formed by winding a plurality of amorphous strips of different sizes. After winding, a step will be formed on the outside of the core.

At the same time, before completing the winding or winding, the iron core needs to be moved to a suitable position, and at this time, the transfer device 4 can transfer the iron core on the rotating device.

[0038] See also Figure 2 The lifting device 1 includes a first linear guide pair 101, a first transmission screw pair 102, a lifting motor 103 and a support plate 104. The first linear guide pair 101 is fixedly connected to the distribution box 6, and the screw nut seat on the first transmission screw pair 102 is fixedly connected to the support plate 104. At the same time, the first transmission screw pair 102 is arranged on the side of the distribution box 6 and is arranged on the same surface as the first linear guide pair 101.

At the same time, the first linear guide pair 101 is set into two, which further improves the stability of the winding device 2 when it moves. The first linear guide pair 101 is provided with a group and the first transmission screw pair 102 is arranged between the two first linear guide pairs 101.

[0039] See also Figure 2-Figure 5The winding device 2 comprises a winding motor 201, a fixed seat 202, an open cylindrical gear 203, a secondary cylindrical gear 204, a secondary pulley 205, a main pulley 206, a transmission belt 207, a connecting shaft 208 and a tape core 209. The side of the fixed seat 202 is fixedly connected to the support plate 104. The winding motor 201 is arranged on the fixed seat 202 and its transmission shaft is connected to the main pulley 206. There are three secondary pulleys 205 arranged at the lower part of the fixed seat 202. There are two secondary cylindrical gears 204, which are respectively connected to the two secondary pulleys 205 on both sides of the fixed seat 202 through the connecting shaft 208. One end of the connecting shaft 208 is connected to the secondary pulley 205 through a bearing and the other end is connected to the secondary cylindrical gear 20 4 is connected, and the middle part is connected to the fixed seat 202 through a bearing. The fixed seat 202 is also provided with an open circular notch 210. The open cylindrical gear 203 is arranged on the open circular notch 210 and can rotate along the open circular notch 210. The tape core 209 is arranged on the upper end surface of the open cylindrical gear 203 for placing the tape roll. The open cylindrical gear 203 is meshed with two sub-cylindrical gears 204 at the same time. The main pulley 206 is connected to the three sub-pulleys 205 through a transmission belt 207. The three sub-pulleys 205 are arranged at the lower part of the fixed seat 202 in an arc array, and the middle sub-pulley 205 is connected to the fixed seat 202 through a connecting shaft 208.

[0040] When the winding motor 201 is in operation, it provides rotational power to the main pulley 206, which then rotates through the transmission belt 207, thereby driving the rotation of the secondary cylindrical gear 204 set on the connecting shaft 208. At the same time, because the secondary cylindrical gear 204 and the open cylindrical gear 203 are meshed with each other, the open cylindrical gear 203 also obtains the rotational power. The reason why the open gear is used to drive the tape core 209 to rotate is that the coil group on the iron core is closed, and the open gear can make the open cylindrical gear 203 be normally installed at the coil position of the iron core. The open cylindrical gear 203 drives the tape core 209 to rotate continuously around the coil group, thereby winding the tape onto the iron core.

[0041] See also Figure 3 and Fig. 9, in order to achieve the purpose of automatic winding. In order to ensure the distance between the tape roll and the iron core, the tape core 209 is designed to be composed of two parts, a bottom plate 209a and a center seat 209b, and the center seat 209b is used to install the tape roll. The bottom plate 209a is fixedly arranged on the upper end surface of the open cylindrical gear 203, and the center seat 209b is fixedly arranged on the bottom plate 209a, so that it can rotate with the rotation of the open cylindrical gear 203. In addition, a stepped arc-shaped waist-shaped hole 209c is arranged on the center seat 209b, and the arc-shaped waist-shaped hole 209c passes through the bottom plate 209a. When the center seat 209b and the bottom plate 209a are connected, a screw is used to pass through the arc-shaped waist-shaped hole 209c and the bottom plate 209a for locking connection. When the distance between the tape roll and the iron core needs to be adjusted, it is only necessary to rotate the bottom plate 209a so that it rotates in the circumferential direction of the arc-shaped waist-shaped hole 209c to complete the distance adjustment.

[0042] See also Figure 7-Figure 8 The rotating device 3 includes a rotating motor 301, a reducer 302, an internal gear slewing bearing 303, a bearing base 304, a slewing gear 305 and a turntable 306. The bearing base 304 is connected to the transfer device 4, the rotating motor 301 is connected to the reducer 302, and the slewing gear 305 is connected to the output shaft of the reducer 302. At the same time, the slewing gear 305 is also meshed with the internal gear slewing bearing 303. The outer ring of the internal gear slewing bearing 303 is connected to the upper end surface of the bearing base 304, and the lower end surface of the turntable 306 is connected to the inner ring of the internal gear slewing bearing 303.

[0043] In this embodiment, the iron core is provided with rotational power by the rotating device 3. The rotating motor 301 provides the rotational power to the rotary gear 305 through the reducer 302 and then transmits it to the internal gear slewing bearing 303, providing the inner ring of the internal gear slewing bearing 303 with rotational power. At this time, the turntable 306 for fixing the iron core is designed on the inner ring of the internal gear slewing bearing 303 to obtain the rotational power. Of course, a clamp for fixing the iron core needs to be designed on the turntable 306 here, because it is a well-known solution for those skilled in the art, it will not be detailed in this case.

[0044] See also Figure 6 Specifically, the transfer device 4 includes a transfer motor 401, a second linear guide pair 402 and a second transmission screw pair 403. The second linear guide pair 402 is provided with a group of screws respectively arranged on both sides of the base 5.

The screw nut seat on the second transmission screw pair 403 and the sliders on the two second linear guide pairs 402 are connected to the bearing base 304. The transfer motor 401 is connected to the screw of the second transmission screw pair 403 through a coupling.

[0045] In this embodiment, a transfer device 4 is provided to facilitate the transfer of the iron core, and a transfer motor 401 provides a rotational force for the second transmission screw pair 403, thereby realizing a linear movement of the rotating device 3 driven by the screw nut seat on the second screw transmission pair 403, and a set of second linear guide rail pairs 402 are designed to ensure the stability of the rotating device 3 during movement.

[0046] Specifically, the distribution box 6 is also provided with a control device for adjusting equipment operating parameters.

[0047] Specifically, the distance between the opening parts of the open cylindrical gear 203 is smaller than the distance between the two outermost subsidiary cylindrical gears 204 arranged on the fixed part.

[0048] In this embodiment, when the open cylindrical gear 203 is disengaged from the two sub-cylindrical gears 204, it will continue to be meshed with the other sub-cylindrical gear 204, ensuring that the open cylindrical gear 203 is meshed with at least one sub-cylindrical gear 204 when operating, thereby continuously providing rotational power for the winding of the tape.

[0049] Working principle: First, the staff will place the iron core that needs to be wrapped with tape on the turntable 306 on the rotating device 3, and then start the equipment. The transfer device 4 drives the rotating device 3 and the iron core to move in the direction of the winding device 2, and the transfer device 4 stops working after reaching the appropriate position. Then the lifting device 1 drives the winding device 2 to descend to the bottom of the area where the iron core needs to be wrapped with tape. And manually pull out the tape placed on the tape core 209, and fix the tape head to the iron core. Then the rotating device 3 and the winding device 2 work at the same time to wrap the tape around the iron core. During the winding process, the lifting device 1 drives the winding device 2 upward to complete the tape winding work in the area where the iron core needs to be wrapped with tape.
