Description

Technical Field

[0001] The utility model relates to the technical field of transformer skeleton production, in particular to a winding device for a transformer skeleton. Background Art

[0002] The transformer skeleton, also known as the transformer wire frame, is the main structural component of the transformer.

[0003] my country's public patent, application number CN202120327691.1, is a winding device for transformers, which specifically mentions: "A small pay-off winch, a movable wire device and a winding action device are arranged on the working platform in sequence. The small pay-off winch is wound and stored with the enameled wire required for the transformer, and the enameled wire passes through the movable wire device and is fed to the winding action device; the winding action device includes an I-shaped skeleton mold, a wire pressing mechanism for pressing and fixing the lead-out end of the enameled wire, and the end side plate of the I-shaped skeleton mold is a detachable plate; the movable wire device includes a wire barrel arranged on a linear servo slide, the wire barrel is arranged horizontally, the enameled wire passes through the wire barrel, and the linear servo slide drives the wire barrel to translate along the axial direction of the I-shaped skeleton mold. The utility model provides a winding device for a transformer, which has a simple structure and is easy to use, greatly improving the production efficiency and yield rate of the transformer."

[0004] The utility model retrieved above realizes the winding of the transformer skeleton, but we found that it still has certain defects during the specific simulation use:

[0005] When the winding of a transformer skeleton is completed, the next transformer skeleton needs to be reinstalled for winding. Before this, since the pulled wire is still wrapped around the transformer skeleton, it is necessary to cut the pulled wire first. The existing technology usually cuts the wire manually, which increases the workload of the staff and reduces efficiency. At the same time, there is a certain tension when the wire is pulled. When the wire is cut, the wire body at one end of the wire may be affected by the tension or tension and rebound, causing the wire to fly, become messy, or even fall out of the wire reel, resulting in the need to re-pass the wire through the wire reel to ensure the normal winding of the transformer skeleton. This undoubtedly affects the normal progress of the winding work and ultimately leads to a reduction in winding efficiency.

[0006] Therefore, we have designed a winding device for a transformer skeleton in a targeted manner to address the technical problems existing in the prior art such as those mentioned above. Utility Model Content

[0033] Specifically, the designed storage frame 14 can store the cutting knife 13 when it is not needed, so that the cutting knife 13 is placed in the storage frame 14, avoiding the cutting knife 13 being placed outside to cause safety hazards.

[0034] In this embodiment, the unwinding assembly includes two mounting plates 5 fixed on the mounting platform 1, a wire unwinding drum 6 is installed between the two mounting plates 5, a wire body 7 is wound on the wire unwinding drum 6, the wire body 7 passes through the conductor drum 9 after being unwound from the wire unwinding drum 6, and the wire body 7 passes through between the two movable plates 15 and between the two cutting knives 13 in turn and is then wound on the transformer skeleton body 12.

[0035] Specifically, the wire unwinding drum 6 can be driven by a motor (the motor is shown in the figure), so that the wire unwinding drum 6 can rotate and realize the unwinding of the wire body 7, so that the wire body 7 can be stably delivered and reeled up by the subsequent transformer skeleton body 12, and the wire body 7 is respectively placed between the two movable plates 15 and the two cutting knives 13, which can also realize the cutting and clamping of the wire body 7.

[0036] In this embodiment, the winding assembly includes a mounting plate 2 10 fixed on the mounting platform 1, a servo motor 3 11 is installed on one side of the mounting plate 2 10, the power output shaft of the servo motor 3 11 movably passes through the mounting plate 2 10 and is fixed with a skeleton mounting block 17, and the skeleton mounting block 17 is sleeved with a transformer skeleton body 12; a cavity is provided inside the skeleton mounting block 17, and a resistance block 20 is slidably connected in the cavity, and an adjusting screw 19 is connected to the internal thread of the resistance block 20, one end of the adjusting screw 19 is rotatably connected to the inner wall of the cavity, and the other end movably passes through the skeleton mounting block 17 and is fixed There is a handle 18, and the abutment block 20 is designed to be an inclined structure; limit blocks 21 are arranged on the top and the right side of the bottom of the skeleton mounting block 17, one side of the limit block 21 is movable through the inside of the cavity and is designed to be inclined to match the abutment block 20, and the other side of the limit block 21 is movable through the skeleton mounting block 17 and fits with the side of the transformer skeleton body 12, and movable plates 22 are fixed on both sides of each limit block 21, and the movable plates 22 are placed in the movable grooves opened inside the skeleton mounting block 17, and a tension spring 23 is fixed on one side of the movable plate 22, and the other end of the tension spring 23 is fixed on the inner wall of the movable groove.

[0037] Specifically, in order to make the transformer skeleton body 12 more stable on the skeleton mounting block 17, structures such as the limit block 21, the adjusting screw 19, the handle 18, the tension spring 23, the movable plate 22 and the resistance block 20 are designed. By rotating the adjusting screw 19, the resistance block 20 can be driven to approach the inclined surfaces of the two limit blocks 21. Since one side of the resistance block 20 is also designed as an inclined surface structure, the resistance block 20 can resist the two limit blocks 21 and move toward the side away from each other when moving, so that the other sides of the two limit blocks 21 can pass through the surface of the skeleton mounting block 17, so as to achieve the effect of fitting on the transformer skeleton body 12 and realize To limit the transformer skeleton body 12, when the transformer skeleton body 12 needs to be removed from the skeleton mounting block 17 later, the staff can reverse the handle 18 and adjust the screw 19 to reverse so that the interference block 20 can be moved away from the two limit blocks 21. At this time, the limit blocks 21 and the movable plate 22 can be reset by the tension spring 23 to drive the two limit blocks 21 to move toward the side close to each other, that is, the two limit blocks 21 can be re-extended into the interior of the skeleton mounting block 17, so that the limit blocks 21 no longer limit the transformer skeleton body 12, and the transformer skeleton body 12 can be easily removed from the skeleton mounting block 17.

[0038] When in use: first install the wire unwinding drum 6 on the mounting plate 5, insert the transformer skeleton body 12 into the skeleton mounting block 17, and turn the adjusting screw 19 through the handle 18. When the adjusting screw 19 rotates, the abutment block 20 is driven to move toward one side of the limit block 21, and as the abutment block 20 contacts the limit block 21, the limit block 21 can be abutted through the inclined surface structure, so that the other sides of the two limit blocks 21 pass through the skeleton mounting block 17 respectively. At this time, the side of the limit block 21 can be used to fit the side of the transformer skeleton body 12, so as to realize the limit of the transformer skeleton body 12 by the limit block 21;

[0039] The wire body 7 is passed through the wire barrel 9, and the wire body 7 is passed through between the two clamping blocks 16 and between the two cutting knives 13 in sequence, and then the wire body 7 can be installed on the transformer skeleton body 12, and the servo motor three 11 and the servo slide 8 are started. The transformer skeleton body 12 is rotated by the drive of the servo motor three 11, and the position of the wire barrel 9 is offset by the servo slide 8, thereby completing the winding action;

[0040] When it is necessary to remove the transformer skeleton body 12 that has been wound and install a new transformer skeleton body 12 to be wound, the staff first starts the servo motor 13, and the power output shaft of the servo motor 13 drives the forward and reverse screws 1301 to rotate, thereby driving the two moving plates 15 to approach each other. When the two moving plates 15 approach and contact the wire body 7 between them, the two clamping blocks 16 can be used to clamp and fix the wire body 7. Then, the servo motor 24 is started, and the power output shaft of the servo motor 24 drives the forward and reverse screws 2401 to rotate. When the forward and reverse screws 2401 rotate, the two moving blocks placed in the storage frame 14 can be driven to approach each other, thereby driving the two cutting knives 13 to approach each other, so as to cut the wire between the two cutting knives 13. At this time, since the wire body 7 is still clamped and fixed by the two clamping blocks 16, the wire body 7 will not fall out of the wire barrel 9 due to the tensioning force.

[0041] Start the servo motor 2 4, and drive the two cutting knives 13 to move away from each other and put them back in the storage frame 14. Then the staff can install the wire body 7 on the transformer skeleton body 12 to be wound and installed on the skeleton mounting block 17. Finally, start the servo motor 1 3, and drive the servo motor 1 3 to move the two clamping blocks 16 away from each other, and no longer apply clamping force to the wire body 7. Then start the servo motor 3 11 to continue the winding work of the transformer skeleton body 12.

[0042] It should be noted that the specific structure of the servo slide 8 is a disclosed technical structure in this technical field, and its working principle is also described in detail in the public patent with application number CN202120327691.1. The servo slide 8 will not be further described in this application.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
