Description

Technical Field

[0001] This utility model relates to the field of transformer processing, and in particular to a transformer coating device. Background Technology

[0002] Transformer encapsulation refers to wrapping insulating tape around key parts of the transformer, either externally or internally, to achieve multiple functions such as insulation protection, fixed support, electromagnetic shielding, moisture and dust prevention, and improved production consistency.

[0003] The reference patent title is: A Transformer Peripheral Tape Winding Device (Patent Publication No.: CN221446971U). The device utilizes a connecting screw to easily move and adjust the position of the tape roller, adapting to different winding positions on the transformer periphery and improving usability. The device allows the tape roller to pass through an electric telescopic rod by engaging and disengaging the locking block and limiting plate. The electric telescopic rod also facilitates the downward movement of the limiting plate, allowing for clamping and limiting of the tape roller with a fixing plate, and facilitating tape roller replacement. A second motor drives the tape roller to rotate, enabling winding on the transformer periphery. Furthermore, a transformer insertion plate is provided to hold the transformer and drive its rotation.

[0004] However, the following problems exist when implementing the above technical solutions: When the above devices change the position of the tape in the transformer tape winding equipment, they mainly rely on manual judgment, making it difficult to quickly locate and ensure the proper position of the tape; The above devices directly change the position of the tape roller by rotating the connecting screw, but due to comprehensive considerations of process flow, equipment design, operational safety, and quality control, there will be a certain distance between the tape roller and the transformer insertion plate. Therefore, the change of the tape roller relative to the transformer insertion plate during the movement of the tape roller cannot be directly observed, and thus the position of the tape relative to the transformer cannot be directly judged. Manual judgment or the use of external reference objects is required. Human judgment is inevitably prone to errors, and multiple fine adjustments may be required afterward.

[0005] Therefore, this utility model proposes a transformer coating device. Utility Model Content

[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0030] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention provides a transformer coating device, including an insertion platform 1 rotatably disposed on the surface of a processing table and a glue-dispensing rack 2 slidably disposed on the surface of the processing table. The glue-dispensing rack 2 has a reference mechanism on its surface for comparing the positions of the insertion platform 1 and the glue-dispensing rack 2. The reference mechanism includes:

[0031] An extension block 3 is rotatably mounted at the bottom of the glue-dispensing rack 2. A limit component is provided between the extension block 3 and the glue-dispensing rack 2 to limit the position of the extension block 3. A reference rod 4 is rotatably connected to the end of the extension block 3. A height-increasing column 5 is slidably connected to the end of the reference rod 4. The height of the height-increasing column 5 is equal to the maximum end face distance between the extension block 3 and the reference rod 4. A fixing component is provided between the height-increasing column 5 and the reference rod 4 to fix the position of the height-increasing column 5.

[0032] The fixing assembly includes a fixing rod 6 and an active rod 7, both of which are slidably disposed inside the reference rod 4. The fixing rod 6 and the active rod 7 are symmetrically arranged relative to the raising column 5. The raising column 5 has two insertion slots 8 on its surface, which are adapted to the fixing rod 6 and the active rod 7. A synchronization assembly is provided between the active rod 7 and the fixing rod 6 to drive them to move towards each other.

[0033] In summary, the transformer coating device provided by this utility model includes an extension block 3 rotatably disposed at the bottom of the coating rack 2. The rotation of the extension block 3 can shorten the relative position between the coating rack 2 and the insertion platform 1. At the same time, a rotating reference rod 4 is provided at the end of the extension block 3. The reference rod 4 can be rotated again to fit against the surface of the insertion platform 1. A sliding height-increasing column 5 is provided at the end of the reference rod 4 to limit the height of the height-increasing column 5 so that the end face of the height-increasing column 5 can be flush with the side of the coating rack 2 away from the processing table. Thus, the position of the end face of the height-increasing column 5 can indicate the position of the bottom of the tape. The height-increasing column 5 can contact the insertion platform 1. Therefore, by observing the position of the end face of the height-increasing column 5, the position of the tape relative to the insertion platform 1 can be directly determined. In conjunction with the transformer, the position of the tape wrapped on the transformer surface can be directly understood. When adjusting the position of the coating rack 2, the adjustment effect can be directly understood through the position of the height-increasing column 5, which is intuitive and can ensure the accuracy of the adjustment result.

[0034] In some specific implementations, an adjusting rod is rotatably connected to the surface of the processing table, the adjusting rod is threadedly connected to the glue-dispensing frame 2, a sliding block is fixedly connected to the surface of the processing table, and a protruding block is fixedly connected to the sliding block. An inner groove is formed on the surface of the glue-dispensing frame 2, and the protruding block is adapted to the inner groove. Rotating the adjusting rod can drive the glue-dispensing frame 2 to slide, changing the height of the glue-dispensing frame 2. When the glue-dispensing frame 2 slides, it can slide against the surface of the sliding block through the inner groove and the protruding block, ensuring the sliding trajectory.

[0035] In some specific implementations, the fixing component includes a plurality of fixing teeth 9 fixedly disposed at the end of the extension block 3 away from the reference rod 4, and a sliding column 10 slidably connected inside the glue-dispensing frame 2. A plurality of sliding teeth 11 are fixedly connected to the end of the sliding column 10, and the sliding teeth 11 mesh with the fixing teeth 9. By setting the sliding column 10, the sliding teeth 11 can be engaged with the fixing teeth 9, or the fixing teeth 9 and the sliding teeth 11 can be disengaged. When the fixing teeth 9 and the sliding teeth 11 are disengaged, the extension block 3 can rotate on the surface of the glue-dispensing frame 2. When the fixing teeth 9 and the sliding teeth 11 are engaged, the extension block 3 cannot continue to rotate.

[0036] In a further embodiment, a fixing spring 12 is fixedly connected between the sliding column 10 and the glue-dispensing frame 2. A sliding shaft 13 is fixedly connected to the surface of the sliding column 10. A sliding groove 14 is provided inside the glue-dispensing frame 2. The sliding groove 14 is adapted to the sliding shaft 13. The sliding groove 14 includes a rectangular groove and an annular groove. The end of the rectangular groove communicates with the annular groove. The sliding groove 14, which is a combination of the rectangular groove and the annular groove, restricts the movement position of the sliding shaft 13. When the sliding shaft 13 is inside the rectangular groove, the sliding shaft 13 can slide. When the sliding shaft 13 is inside the annular groove, the sliding shaft 13 can rotate, thus preventing the sliding column 10 from resetting under the action of the fixing spring 12.

[0037] In some specific implementations, the synchronization assembly includes synchronization rods fixedly disposed on the surfaces of the fixed rod 6 and the active rod 7, a synchronization belt 15 fixedly connected between the synchronization rods, a transfer rod fixedly connected inside the reference rod 4, the synchronization belt 15 being slidably connected to the transfer rod, and the distance between the transfer rod and the heightening column 5 being greater than the distance between the fixed rod 6 and the heightening column 5; a synchronization spring is disposed between the fixed rod 6 and the reference rod 4; by setting the transfer rod, the synchronization belt 15 can be made C-shaped, so that when the active rod 7 moves away from the heightening column 5, it can pull the synchronization belt 15, causing the fixed rod 6 to move away from the heightening column 5;

[0038] In a further embodiment, an operating rod 16 is rotatably connected to the surface of the active rod 7, and an operating column 17 is fixedly connected to the surface of the operating rod 16. The surface of the reference rod 4 is provided with a moving groove and a meandering groove 18. The operating rod 16 is adapted to the moving groove, and the moving groove and the meandering groove 18 are connected. The meandering groove 18 is J-shaped, and the operating column 17 is adapted to the meandering groove 18. When the operating column 17 slides to the curved end of the meandering groove 18, the operating rod 16 cannot continue to move, and the active rod 7 cannot slide, thus preventing the synchronous spring from pulling the fixed rod 6 to slide, and pulling the active rod 7 to move through the synchronous belt 15.

[0039] In some specific implementations, an extension rod 19 is slidably connected to the surface of the adhesive tray 2. The opposing surfaces of the extension rod 19 and the adhesive tray 2 are in contact with the adhesive tape. A cylinder 20 is fixedly connected to the surface of the adhesive tray 2. The end of the piston rod inside the cylinder 20 is detachably connected to the extension rod 19. A support rod 21 is rotatably connected to the surface of the extension rod 19. A stop post is rotatably connected to the opposing surfaces of the support rod 21 and the extension rod. A positioning component is provided between the support rod 21 and the extension rod 19 to limit the angle between them. The angle between the reference rod 4 and the extension block 3 is limited by the positioning component. The extension rod 19 is detachably connected to the cylinder 20, so that the position of the extension rod 19 and the adhesive tray 2 can be adjusted according to the height of the adhesive tape. At the same time, the extension rod 19 can be completely detached from the adhesive tape, which is convenient for placing the adhesive tape on the surface of the adhesive tray 2.

[0040] In a further embodiment, the abutting column includes a base column and a sliding rod, the sliding rod slides inside the base column, and the end of the sliding rod is rotatably connected to the inside of the support rod 21, and the base column is rotatably connected to the inside of the extension rod;

[0041] In a further embodiment, an arc-shaped groove is provided at the end of the piston rod inside the cylinder 20. The arc-shaped groove is a semi-open groove. A disassembly post is fixedly connected to the surface of the extension rod 19. The disassembly post is adapted to the arc-shaped groove.

[0042] In a further embodiment, the positioning component includes a plurality of limiting teeth 22 fixedly disposed at the end of the support rod 21, and a positioning rod 23 is internally threadedly connected to the extension rod 19. A plurality of positioning teeth are fixedly connected to the end of the positioning rod 23, and the limiting teeth 22 and the positioning teeth mesh.

[0043] The working principle of this utility model:

[0044] Before adjusting the position of the glue rack 2, first slide the column 10 to disengage the sliding tooth 11 from the fixed tooth 9, then rotate the column 10 to make the sliding shaft 13 fit into the annular groove, rotate the extension block 3, then rotate the positioning rod 23 at the end of the reference rod 4 to disengage the positioning tooth and the limiting tooth 22, rotate the reference rod 4 to make the surface of the reference rod 4 fit into the insertion platform 1, reset the column 10 and the positioning rod 23, then pull the active rod 7 to pull the synchronous belt 15 to move the fixed rod 6, rotate the rod to disengage from the insertion groove 8, slide the raising column 5 to make one side of the raising column 5 flush with one side of the glue rack 2, and then reset the active rod 7.

[0045] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
