[0034] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0035] The invention provides Figures 1 to 3 As shown, a transformer winding folding device comprises:

[0036] The machine base 11, the adjustment base 13 and the mounting base 14 are both escalably mounted on the machine base 11, the adjustment base 13 is mounted with a winding base 18, the mounting base 14 is mounted with an outlet tube 17, the enameled wire passes through the outlet tube 17 and is wound on the transformer, and the outlet tube 17 is moved back and forth in the vertical direction to operate the transformer;

[0037] It also includes a linear adjustment component, a counter, a folding line component and a paint removal component. Two sets of position-adjustable displacement sensors 24 are installed on the linear adjustment component. A positioning member 22 is correspondingly provided on the outlet tube 17. The positioning member 22 is used to calibrate the height position of the outlet tube 17. The positioning member 22 moves between the two sets of displacement sensors 24. The displacement sensor 24 identifies the winding position of the outlet tube 17 through the positioning member 22.

[0038] When the displacement sensor 24 detects that the outlet tube 17 is located at the end of the transformer, the folding line component is triggered; when the counter determines that the transformer has completed the predetermined number of turns of the coil, the paint removal component is triggered.

[0039] Specifically, Figure 2 As shown, in order to achieve the adjustment of the two groups of displacement sensors 24, a mounting rod 19 is included, the mounting rod 19 is mounted on the machine base 11 or the adjustment base 13, two groups of adjustment blocks 23 are slidably mounted on the mounting rod 19, the displacement sensor 24 is mounted on the adjustment block 23, and the linear adjustment component is provided with two groups, which are respectively used for position adjustment of the two groups of adjustment blocks 23 (i.e., displacement sensors 24), and the spacing between the two groups of displacement sensors 24 is the winding range of the transformer. By real-time tracking the position change of the outlet tube 17 during winding through two groups of displacement sensors 24, the winding position of the enameled wire can be accurately and effectively determined, thereby providing accurate trigger instructions for triggering the folding component and the paint removal 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 located on one side of the transformer, and are stored in a position that does not interfere with the winding of the transformer by rotating the driving member 28. When the transformer is wound to the end, the lever 210 is driven to rotate by rotating the driving member 28, and the adjusting rod 29 is extended and retracted to adjust the position of the guide wheel 211 to perform a folding operation at both ends of the transformer.

[0044] like Figures 6 to 8 As shown, since the enameled wire at the end of the transformer after winding needs to be exposed, it is necessary to strip the enameled wire at a specific position. In order to solve this problem, the paint stripping component includes a paint stripping component 31 and a paint scraping component 32. The paint stripping component 31 includes an immersion chamber 38. The immersion chamber 38 is provided with a paint stripping liquid that can be controlled to circulate. The paint stripping component 31 is located in the vertical direction of the immersion chamber 38 and has multiple groups of second threading holes 34. The number of the second threading holes 34 is consistent with the number of the outlet tube 17. The enameled wire passes through the second threading holes 34 of the paint stripping component 31 and the paint scraping component 32 to guide the outlet tube 17. After the enameled wire is immersed in the paint stripping liquid inside the paint stripping component 31, it is led to the paint scraping component 32 for paint scraping operation, thereby processing the enameled wire that needs to be exposed at the end of the transformer. Optionally, in actual use, the paint stripping component is installed on the back of the mounting seat 14 so that the paint stripping component follows the position of the outlet tube 17.

[0045] like Figure 6 As shown, regarding the circulation problem of the paint stripping liquid inside the immersion chamber 38, the paint stripping component 31 is provided with a first pipe 36 and a second pipe 37 connected to the immersion chamber 38. The first pipe 36 and the second pipe 37 cooperate with an external container to circulate the paint stripping liquid inside the immersion chamber 38, and the immersion time of the enameled wire in the immersion chamber 38 is controlled by PLC control.

[0046] The paint scraping assembly 32 is mounted on the paint stripping assembly 31. The paint scraping assembly 32 is provided with a first threading hole 33. The first threading hole 33 is aligned with the second threading hole 34. The paint scraping assembly 32 includes two sets of paint scraping parts. The two sets of paint scraping parts are provided with grooves. The grooves on the two sets of paint scraping parts form the first threading hole 33. Figure 6 As shown, the two groups of paint scrapers are moved closer and further away via a driving structure. When the two groups of paint scrapers are close to the limit distance, the surface of the enameled wire is scraped via the first threading hole 33. The paint scraper assembly 32 is provided with a wiping member 35. The paint scraper assembly 32 scrapes the enameled wire that has been immersed in the paint and wipes the surface via the wiping member 35, thereby obtaining a better paint removal operation.

[0047] More importantly, the paint stripping liquid in the immersion chamber 38 inside the paint stripping component 31 is not constantly circulating, and the paint scraping component 32 is not constantly performing the paint scraping operation. Paint stripping is performed only when the enameled wire is wound on the transformer to the end and needs to be exposed. The rest of the time, the enameled wire directly passes through the paint stripping component 31 and the paint scraping component 32 without being stripped. Therefore, the operation time of the paint stripping component 31 and the paint scraping component 32 is the most critical. It also includes a PLC controller and a counter. The counter is used to count the number of winding coils of the transformer (the key parameters of the transformer include the number of turns of the winding). With the cooperation of the positioning member 22 and the displacement sensor 24, when the transformer meets the predetermined number of winding coils and the 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 stripping operation. The starting operation time of the two is adjusted according to the paint stripping effect of the enameled wire, and the starting operation time can be adjusted through the PLC controller.

[0048] The adjusting seat 13 is provided with a plurality of winding seats 18, and the winding seats 18 are used for the winding installation and synchronous rotation of the transformer. The winding seat 18 is provided with an ejection assembly 111, which is used to eject the transformer that has been wound on the winding seat 18, so as to facilitate the subsequent installation of the transformer on the winding seat 18. The adjusting seat 13 is provided with a driver 110 for synchronously driving the plurality of winding seats 18, and the driver 110 is configured as a servo motor. Due to the winding operation of the transformer, different types of transformers may be installed on the winding seat 18, and different rotation speeds can be adjusted by the servo motor to adapt to different forms of rotating winding of the winding seat 18.

[0049] like Figure 1 and Figure 3 As shown, in order to achieve height adjustment control of the adjustment seat 13 and the mounting seat 14, a first screw rod 12 for driving the adjustment seat 13 to be raised and lowered is installed on the machine base 11, and a second screw rod 15 for driving the adjustment seat 14 to be raised and lowered is installed on the machine base 11. The driving source of the first screw rod 12 and the second screw rod 15 is a servo motor, which is used to achieve fine forward and reverse adjustment of the first screw rod 12 and the second screw rod 15. Since the winding operation of the enameled wire of the transformer requires the outlet tube 17 to make fine vertical displacement, the servo motor is used as the driving source of the displacement structure.

[0050] The embodiments of the present invention are described above, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms, which are all within the protection of the present invention.
