DETAILED DESCRIPTION

[0032] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] The transformer coil winding device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the transformer coil winding device according to the embodiment of the present application may include a winding machine body 100 , a knocking device 200 , a pressing device 300 and an auxiliary rod 400 .

[0035] The iron core 500 is disposed on the main shaft 101 of the winding machine body 100 , the flat copper wire 600 passes through the reciprocating wire feeding end of the winding machine body 100 and is wound around the iron core 500 , and the flat copper wire 600 is coated with an insulating layer.

[0036] The knocking device 200 is disposed on the reciprocating wire feeding end of the winding machine body 100 .

[0037] As a possible situation, the striking end of the striking device 200 is arranged above the iron core 500 , and the flat copper wire 600 can be more closely fitted to the outer contour of the iron core 500 by rapid hammering.

[0038] like Figure 2 and Figure 7 As shown, the pressing device 300 includes a rotating shaft 310 , an elastic pressing structure 320 , a first spring 330 and a driving structure 340 .

[0039] The rotating shaft 310 is disposed on the winding machine body 100 and is connected to the driving structure 340 , and the elastic pressing structure 320 is constrained to be slidable only along the length direction of the rotating shaft 310 .

[0040] It should be noted that the elastic pressing structure 320 can only slide along the length direction of the rotating shaft 310, and is limited in other directions. Therefore, when the rotating shaft 310 rotates, the elastic pressing structure 320 can be driven to rotate.

[0041] As a possible situation, the driving structure 340 includes a support rod 341 and a first driving cylinder 342, wherein the support rod 341 is vertically arranged on the rotating shaft, one end of the first driving cylinder 342 is pivotally arranged on the winding machine body 100, and the other end is pivotally connected to the support rod 341. When the first driving cylinder 342 is extended or retracted, the support rod 341 is pushed to drive the rotating shaft 310 to rotate.

[0042] The two first springs 330 are respectively disposed on two sides of the elastic pressing structure 320 .

[0043] It should be noted that the first spring 330 is sleeved on the rotating shaft 310, and one end of the first spring 330 is connected to the elastic clamping structure 320, and the other end is fixed to the end of the rotating shaft 310 or the winding machine body 100. When the clamping structure moves, one of the two springs is subjected to a tensile force and the other is subjected to a compressive force.

[0044] The elastic pressing end of the elastic pressing structure 320 abuts against the iron core 500 .

[0045] It should be noted that the elastic clamping end of the elastic clamping structure 320 can be automatically adjusted according to the iron core 500 and the wound flat copper wire 600 to ensure that the elastic clamping end of the elastic clamping structure 320 can always maintain contact with the iron core 500 or the wound flat copper wire 600.

[0046] like Figure 2 and Fig. 9 As shown, the auxiliary rod 400 is arranged above the clamping device 300, and limit switches 401 are respectively arranged at both ends of the auxiliary rod 400. When the flat copper wire 600 is wound to the end of the iron core 500, the top of the elastic clamping structure 320 contacts the limit switch 401 at this end to trigger the driving structure 340 to drive the rotating shaft 310 to rotate, and after the elastic clamping structure 320 is reset to the center position of the iron core 500, it drives the rotating shaft 310 to reset, so that the elastic clamping end of the elastic clamping structure 320 abuts against the wound flat copper wire 600.

[0047] Specifically, when the relevant staff is performing the winding operation on the flat copper wire 600, first, the relevant staff installs the iron core 500 on the winding machine body 100, and then passes the flat copper wire 600 through the reciprocating wire feeding end of the winding machine body 100 and winds it on the iron core 500. At this time, the elastic clamping end of the elastic clamping structure 320 is pressed on the iron core 500, and the two first springs 330 are not subjected to force, and at this time the elastic clamping structure 320 is located at the center of the iron core 500.

[0048] Then start the winding machine body 100 and the knocking device 200. As the winding machine body 100 winds the flat copper wire 600 around the iron core 500, the knocking device 200 moves along with the reciprocating wire feeding end of the winding machine body 100 and hammers the flat copper wire 600, so that the flat copper wire 600 fits the outer contour of the iron core 500 more closely.

[0049] As the flat copper wire 600 is routed and wound on the iron core 500, the flat copper wire 600 gradually approaches the elastic clamping structure 320 and pushes the elastic clamping structure 320 to move. At this time, the first spring 330 is subjected to force, and due to its own restoring effect, it drives the elastic clamping structure 320 to squeeze the flat copper wire 600, so that the flat copper wires 600 are tighter. As the elastic clamping structure 320 moves, the greater its restoring force, the better the overall tightness of the flat copper wire 600.

[0050] When the flat copper wire 600 is wound to the end position of the iron core 500, the top of the elastic clamping structure 320 contacts the limit switch 401, and the limit switch 401 triggers the driving structure 340 to drive the rotating shaft 310 to rotate. At this time, the elastic clamping structure 320 rotates with the rotating shaft 310 and breaks away from the contact with the iron core 500. Due to the reset action of the first spring 330, the elastic clamping structure 320 resets to the center position of the iron core 500. The driving structure 340 can drive the rotating shaft 310 to rotate and reset at a preset time interval. At this time, the elastic clamping end of the elastic clamping structure 320 is pressed on the already wound flat copper wire 600, and the winding machine body 100 drives the flat copper wire 600 in the opposite direction to wind the next layer. The elastic clamping structure 320 waits for the next layer of flat copper wire 600 to approach, and pushes the next layer of flat copper wire 600, so that the next layer of flat copper wire 600 is tightly arranged, and so on.

[0051] It should be noted that the elastic clamping structure 320 acts from the center of the iron core 500, which can avoid squeezing and falling off caused by insufficient stability in the initial winding stage of the flat copper wire 600. After the flat copper wire 600 is wound for a certain distance, there is a basic fit between the flat copper wire 600 and the iron core 500. At this time, pushing the flat copper wire 600 tight can more effectively make the adjacent flat copper wires 600 closer.

[0052] In one embodiment of the present application, Figure 4 and Figure 5 As shown, the striking device 200 includes a first driving motor 210 , a rotating disk 220 , an eccentric rod 230 , a sleeve 240 , a first elastic telescopic rod 250 and a rubber hammer 260 .

[0053] A connecting frame 102 is provided on the reciprocating wire feeding end of the winding machine body 100 , and a mounting frame 103 is provided at the end of the connecting frame 102 .

[0054] The first drive motor 210 is arranged on the connecting frame 102, the turntable 220 is arranged on the output end of the first drive motor 210, the eccentric rod 230 is eccentrically arranged on the turntable 220, the sleeve 240 is fixedly arranged on the mounting frame 103, the first elastic telescopic rod 250 slides and is sleeved in the sleeve 240, and one end of the first elastic telescopic rod 250 is pivotally connected to the eccentric rod 230, and the other end is connected to the rubber hammer 260.

[0055] It should be noted that when the knocking device 200 is started, the first drive motor 210 drives the turntable 220 to rotate, so that the eccentric rod 230 rotates accordingly, thereby driving the first elastic telescopic rod 250 to move up and down, thereby realizing the knocking action of the rubber hammer 260 on the flat copper wire 600.

[0056] It is understandable that as the flat copper wire 600 is wound around the iron core 500 , the outer contour of the coil increases. At this time, the first elastic telescopic rod 250 can change along with the outer contour of the coil to ensure that the rubber hammer 260 effectively hammers the flat copper wire 600 .

[0057] In addition, a movable sliding sleeve 402 is sleeved on the auxiliary rod 400, and the sliding sleeve 402 is embedded in the connecting frame 102, so that when the knocking device 200 moves with the movement of the winding machine body 100 to feed the wire, the stability is higher.

[0058] In one embodiment of the present application, Figure 8 As shown, the elastic pressing structure 320 includes a sliding body 321 , a limiting block 322 , a trigger head 323 and a second elastic telescopic rod 324 .

[0059] Among them, the rotating shaft 310 is provided with a sliding groove along the length direction, the limit block 322 is arranged in the sliding body 321, and the sliding body 321 is sleeved on the rotating shaft 310, the limit block 322 is slidably connected to the sliding groove, the trigger head 323 and the second elastic telescopic rod 324 are respectively arranged on the sliding body 321, wherein the trigger head 323 is located between the two limit switches 401, and the rod end of the second elastic telescopic rod 324 abuts against the outer side of the outermost circle of the flat copper wire 600.

[0060] It should be noted that when the rotating shaft 310 rotates, the limiting block 322 is limited by the sliding groove, so that the sliding body 321, the second elastic telescopic rod 324 and the trigger head 323 can be driven to rotate.

[0061] It should be noted that the two limit switches 401 are respectively connected to the driving structure 340 through the controller.

[0062] To clearly explain the above embodiment, in one embodiment of the present invention, Figure 6As shown, the first elastic telescopic rod 250 and the second elastic telescopic rod 324 both include a rod sleeve 251 , a push rod 252 and a second spring 253 .

[0063] The sliding sleeve 402 of the push rod 252 is disposed in the rod sleeve 251 , the second spring 253 is disposed in the rod sleeve 251 , and two ends of the second spring 253 are respectively connected to the push rod 252 and the rod sleeve 251 .

[0064] It should be noted that when the push rod 252 is subjected to force, it can slide in the rod sleeve 251 by squeezing the second spring 253 .

[0065] The push rod 252 of the first elastic telescopic rod 250 is pivotally connected to the eccentric rod 230 , and the rubber hammer 260 is disposed on the rod sleeve 251 of the first elastic telescopic rod 250 .

[0066] It should be noted that when the knocking device 200 performs a knocking operation, as the number of winding layers of the flat copper wire 600 increases, when the rubber hammer 260 hammers the flat copper wire 600, the second elastic telescopic rod 324 changes in length during hammering, that is, the push rod 252 is forced to squeeze the second spring 253, causing the push rod 252 to slide in the rod sleeve 251.

[0067] The rod sleeve 251 of the second elastic telescopic rod 324 is connected to the sliding body 321 . The end of the push rod 252 of the second elastic telescopic rod 324 is arc-shaped and abuts against the outermost circle of the flat copper wire 600 .

[0068] It should be noted that when the elastic compression structure 320 compresses the flat copper wire 600 , as the number of winding layers of the flat copper wire 600 increases, the length of the second elastic telescopic rod 324 changes, that is, the push rod 252 is forced to squeeze the second spring 253, causing the push rod 252 to slide in the rod sleeve 251.

[0069] In one embodiment of the present application, Figure 3 As shown, the winding machine body 100 includes a body 110 , a support structure 120 and a wire feeding structure 130 .

[0070] The fuselage 110 and the support structure 120 are arranged opposite to each other, and the iron core 500 is detachably arranged between the fuselage 110 and the support structure 120. The wire feeding structure 130 is arranged on the fuselage 110 through the fixing frame 104, and the flat copper wire 600 passes through the wire feeding end of the wire feeding structure 130 and is wound around the iron core 500.

[0071] To clearly illustrate the above embodiment, in one embodiment of the present application, the support structure 120 includes a support tail frame 121 , a second driving cylinder 122 and a fixing flange 123 .

[0072] The second driving cylinder 122 is disposed on the supporting tail frame 121 , and the fixing flange 123 is rotatably disposed on the telescopic end of the second driving cylinder 122 .

[0073] One end of the iron core 500 is detachably connected to the main shaft 101 , and the other end is detachably connected to the fixing flange 123 .

[0074] It should be noted that when installing the iron core 500, firstly, one end of the iron core 500 is fastened to the flange on the main shaft 101 by bolts, and then the second driving cylinder 122 is started, so that the second driving cylinder 122 pushes the fixed flange 123 until it contacts the other end of the iron core 500, and then fastened by bolts. The relevant staff can start the fuselage 110 so that the rotating structure in the fuselage 110 drives the main shaft 101 and the iron core 500 to rotate, so as to achieve the winding operation.

[0075] In one embodiment of the present application, Figure 4 As shown, the wire feeding structure 130 includes a second driving motor 131 , a reciprocating screw 132 , a screw slider 133 , a wire feeding frame 134 and a guide wheel 135 .

[0076] Among them, the second drive motor 131 is arranged on the fixed frame 104, the reciprocating screw 132 is rotatably arranged between the fixed frame 104 and the support structure 120, and is connected to the output end of the second drive motor 131, the screw slider 133 is arranged on the reciprocating screw 132, the wire feeding frame 134 is arranged on the screw slider 133, and a plurality of guide wheels 135 are rotatably arranged on the wire feeding frame 134.

[0077] It should be noted that when the relevant staff winds the flat copper wire 600 on the iron core 500, first, the flat copper wire 600 passes through the guide wheel 135 and is wrapped around one end of the iron core 500 for fixation, and then the second drive motor 131 is started to rotate the reciprocating screw 132, and the screw slider 133 moves on the reciprocating screw 132, and drives the wire feeding frame 134, the guide wheel 135 and the flat copper wire 600 to move synchronously to achieve a uniform winding operation.

[0078] To clearly illustrate the previous embodiment, in one embodiment of the present application, there are multiple guide wheels 135 , which are staggered up and down, and the flat copper wire 600 passes between the staggered guide wheels 135 to improve the stability of the transmission of the flat copper wire 600 on the guide wheel 135 .

[0079] In summary, according to the transformer coil winding device of the embodiment of the present application, the knocking device 200 follows the reciprocating moving end of the wire feeding device to move synchronously, and can knock the flat copper wire 600 when it is wound on the iron core 500, so that it fits better with the surface of the iron core 500. The clamping end of the clamping device 300 can dynamically clamp the flat copper wire 600, so that the flat copper wire 600 wound on the iron core 500 is tighter, thereby improving the electrical performance.
