Description

Technical Field

[0001] The present invention relates to the technical field of transformer winding coils, and particularly relates to a transformer winding folding device. Background Art

[0002] The general process of manufacturing a transformer usually includes several steps such as winding, winding insulating tape, folding the leads of the winding, and winding insulating tape on the leads. However, currently, the step of folding the leads of the winding can only be completed manually, resulting in the inability to complete other steps on a machine, making the overall production efficiency relatively low and unable to meet the requirements of large-scale and rapid production.

[0003] The prior art discloses a folding mechanism for a transformer winding machine, with the application number CN202122686817.7. By setting a toothed plate, a fixed housing, a first motor, a first gear, and an L-shaped fixing plate, the heights of the guide pin rod and the wire deflecting rod can be adjusted according to the actual situation of the transformer winding machine, thereby preventing the guide wheel from being unable to fold the two leads of the transformer pin due to too high a position and avoiding affecting the production efficiency of the transformer. However, the following technical problems still exist in this solution:

[0004] In this solution, when a folding operation needs to be performed on the transformer, the positions of the wire deflecting rod and the guide wheel are only applicable to the folding operation at one end of the transformer. However, in the actual winding operation of the transformer, winding operations are required at both ends; in addition, when the winding of the transformer reaches the end, the end of the enameled wire needs to be exposed for subsequent wiring operations. Therefore, we need to provide a transformer winding folding device. Summary of the Invention

[0034] Reference will now be made to example embodiments to discuss the subject matter described herein. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. In addition, the features described in some examples can also be combined in other examples.

[0035] The invention provides as Figures 1 to 3 shown, a transformer winding folding line device, comprising:

[0036] A machine base 11, an adjusting base 13 and a mounting base 14. The adjusting base 13 and the mounting base 14 are both installed on the machine base 11 in a liftable manner. A winding base 18 is installed on the adjusting base 13, and a wire outlet pipe 17 is installed on the mounting base 14. The enameled wire passes through the wire outlet pipe 17 and is wound around the transformer. The wire outlet pipe 17 reciprocates vertically to perform operations on the transformer;

[0037] It further includes a linear adjustment component, a counter, a folding line component and a paint removing component. Two sets of position-adjustable displacement sensors 24 are installed on the linear adjustment component. A positioning member 22 is correspondingly arranged on the wire outlet pipe 17. The positioning member 22 is used to calibrate the height position of the wire outlet pipe 17. The positioning member 22 moves between the two sets of displacement sensors 24. The displacement sensors 24 identify the winding position of the wire outlet pipe 17 through the positioning member 22;

[0038] When the displacement sensor 24 detects that the wire outlet pipe 17 is at the end position of the transformer, the folding line component is triggered; when the counter determines that the transformer has wound a predetermined number of turns of the coil, the paint removing component is triggered.

[0039] Specifically, as Figure 2 shown, in order to realize the adjustment of the two sets of displacement sensors 24, it includes a mounting rod 19. The mounting rod 19 is installed on the machine base 11 or the adjusting base 13. Two sets of adjusting blocks 23 are slidably installed on the mounting rod 19. The displacement sensors 24 are installed on the adjusting blocks 23. Two sets of linear adjustment components are provided, respectively used for adjusting the positions of the two sets of adjusting blocks 23 (i.e., the displacement sensors 24). The distance between the two sets of displacement sensors 24 is the winding range of the transformer. By using the two sets of displacement sensors 24 to track the position change of the wire outlet pipe 17 during winding in real time, the winding position of the enameled wire can be accurately and effectively judged, and then accurate trigger instructions can be provided for triggering the folding line component and the paint removing component.

[0040] The linear adjustment component is configured as a bidirectional screw 21, a position adjustment member 26 is installed on the mounting rod 19, the position adjustment member 26 is configured as an electric telescopic push rod, a driving motor 25 is installed on the movable end of the position adjustment member 26, the bidirectional screw 21 is installed on the output end of the driving motor 25, the position adjustment member 26 is used to adjust the position of the linear adjustment component to adapt to the winding area of different transformers, and two groups of adjustment blocks 23 are threadedly installed at both ends of the bidirectional screw 21, so that the bidirectional screw 21 can synchronously adjust the two groups of adjustment blocks 23 to move closer or farther away from each other. Figure 5 As shown, this embodiment requires that the bidirectional screw rod 21 and the transformer to be wound be aligned, and an alignment mark is set in the middle position of the bidirectional thread of the bidirectional screw rod 21. The specific alignment method is to align the alignment mark with the middle position of the transformer to be wound.

[0041] The mounting seat 14 is provided with a fixing seat 16 for installing the outlet tube 17 . The positioning member 22 is installed on the fixing seat 16 and maintained at the same height as the outlet tube 17 . The positioning member 22 and the outlet tube 17 are staggered to avoid interference with the outlet wire of the enameled wire in the outlet tube 17 .

[0042] During the transformer winding process, the transformer's folding operation is not only folded in one direction, but also needs to be folded at both ends of the transformer. In order to solve this problem, Figure 4 and Figure 5 As shown, the folding line assembly includes a rotating drive member 28 and an adjusting rod 29, the adjusting rod 29 is installed on the output end of the rotating drive member 28, the rotating drive member 28 is rotationally driven, and the adjusting rod 29 is telescopically driven. A lever 210 is installed on the telescopic end of the adjusting rod 29, and a guide wheel 211 is rotatably installed at the end of the lever 210. The rotating drive member 28 and the adjusting rod 29 are provided in two groups, and the two groups of rotating drive members 28 are symmetrically arranged on one side of the winding seat 18, the purpose is to align the transformer workpiece to be wound installed on the winding seat 18, and the actual installation position of the two groups of rotating drive members 28, as shown in FIG. Figure 5 As shown, optionally, the rotating drive member 28 is mounted on the fixed seat 16 via a connecting plate 27. In actual usage scenarios, the connecting plate 27 is detachably mounted on the fixed seat 16 and can be adjusted according to the size of the transformer model of the current processing batch, so that the rotating drive member 28 and the adjustment rod 29, the lever 210 and the guide wheel 211 and other structures can adapt to the size of the transformer.

[0043] like Figure 4 and Figure 5As shown, the lever 210 and the guide wheel 211 aligned with the position of the transformer being wound are on one side of the transformer. They are rotated and stored in a position that does not interfere with the winding of the transformer by the rotation driving member 28. When the transformer is wound to the end, the lever 210 is driven to rotate by the rotation driving member 28, and the position of the guide wheel 211 is adjusted by the telescopic movement of the adjusting rod 29 to perform a folding line operation at both ends of the transformer.

[0044] As Figures 6 to 8 shown, since the enameled wire at the end of the wound transformer needs to be exposed, the enameled wire needs to be de-painted at a specific position. To solve this problem, the de-painting assembly includes a de-painting component 31 and a scraping component 32. The de-painting component 31 includes an immersion chamber 38, and a de-painting liquid that can be controlled to circulate is provided inside the immersion chamber 38. The de-painting component 31 is provided with a plurality of groups of second wire-passing holes 34 in the vertical direction of the immersion chamber 38. The number of the second wire-passing holes 34 is the same as the number of the wire outlet pipes 17. The enameled wire passes through the second wire-passing holes 34 of the de-painting component 31 and is guided to the wire outlet pipe 17 by the scraping component 32. After being soaked in the de-painting liquid inside the de-painting component 31, the enameled wire leads to the scraping component 32 for scraping operation, so as to process the enameled wire that needs to be exposed at the end of the transformer. Optionally, in the actual use process, the de-painting assembly is installed on the back of the mounting seat 14 so that the de-painting assembly follows the position of the wire outlet pipe 17.

[0045] As Figure 6 shown, regarding the circulation problem of the de-painting liquid inside the immersion chamber 38, the de-painting component 31 is provided with a first pipe 36 and a second pipe 37 communicating with the immersion chamber 38. The de-painting liquid inside the immersion chamber 38 is circulated by the cooperation of the first pipe 36 and the second pipe 37 with an external container. The soaking time of the enameled wire inside the immersion chamber 38 is controlled by a PLC.

[0046] The scraping component 32 is installed on the de-painting component 31. The scraping component 32 is provided with a first wire-passing hole 33. The first wire-passing hole 33 is aligned with the second wire-passing hole 34. The scraping component 32 includes two groups of scraping members. Grooves are provided on both groups of scraping members. The grooves on the two groups of scraping members form the first wire-passing hole 33. As Figure 6 shown, the two groups of scraping members are operated to approach and move away from each other through a driving structure. When the two groups of scraping members approach to the limit distance, the surface of the enameled wire is scraped through the first wire-passing hole 33. A wiping member 35 is provided on the scraping component 32. The scraping component 32 performs a scraping operation on the soaked enameled wire and wipes the surface through the wiping member 35, so as to obtain a better de-painting surface operation.

[0047] More importantly, the paint stripping liquid in the immersion liquid chamber 38 inside the paint stripping component 31 does not circulate continuously, and the paint scraping component 32 does not perform the paint scraping operation continuously. Only when the enameled wire winds to the end on the transformer and needs to be exposed, the paint stripping treatment is carried out. During the rest of the time, the enameled wire directly passes through the paint stripping component 31 and the paint scraping component 32 without performing the paint stripping operation. Therefore, the operation time of the paint stripping component 31 and the paint scraping component 32 is the most crucial. It also includes a PLC controller and a counter. The counter is used to count the number of winding turns of the transformer (the key parameters of the transformer include the number of winding turns). With the cooperation of the positioning member 22 and the displacement sensor 24, when the transformer meets the predetermined number of winding turns and the wire outlet pipe 17 reaches the end position of the transformer, the paint stripping component 31 and the paint scraping component 32 are started to perform the paint removal operation. The start operation time of the two is adjusted according to the paint stripping effect of the enameled wire, and the start operation time can be adjusted through the PLC controller.

[0048] A plurality of winding seats 18 are installed on the adjusting seat 13. The winding seats 18 are used for the winding installation and synchronous rotation of the transformer. A jacking component 111 is arranged on the winding seat 18, which is used to jack out the transformer that has completed winding on the winding seat 18 to facilitate the subsequent installation of the transformer on the winding seat 18. A driver 110 for synchronously driving the plurality of winding seats 18 is installed on the adjusting seat 13. The driver 110 is set as a servo motor. Since the winding operation of the transformer is involved, different models of transformers may be correspondingly installed on the winding seat 18, and the servo motor can be used to adjust different rotation speeds to adapt to different forms of rotational winding of the winding seat 18.

[0049] As Figure 1 and Figure 3 As shown, in order to realize the height adjustment control of the adjusting seat 13 and the mounting seat 14, a first lead screw 12 for driving the lifting adjustment of the adjusting seat 13 is installed on the machine base 11, and a second lead screw 15 for driving the lifting adjustment of the mounting seat 14 is installed on the machine base 11. The driving sources of the first lead screw 12 and the second lead screw 15 are servo motors, which are used to realize the fine forward and reverse adjustment of the first lead screw 12 and the second lead screw 15. Since the enameled wire winding operation of the transformer requires the wire outlet pipe 17 to make a fine displacement in the vertical direction, a servo motor is used as the driving source of the displacement structure.

[0050] The embodiments of the present invention have been described above, but the present invention is not limited to the above specific embodiments. The above specific embodiments are only illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the present invention.
