Description

Technical Field

[0002] Foil coil winding machines (hereinafter referred to as foil winding machines) are specialized equipment for transformers that produce round, square, or rectangular coiled dry-type low-voltage coils. Generally, double-foil overlapping winding involves the two foils being completely bonded together without any insulation in between, with only an insulation layer added to the inner surface of the lower foil strip. Currently, there is a need to add interlayer insulation between the two foils during double-layer overlapping winding, but existing foil coil winding equipment cannot meet this requirement. Summary of the Invention

[0003] The purpose of this invention is to provide a coil stacking and winding mechanism and process with interlayer insulation between double foils, so as to overcome the above-mentioned technical defects.

[0004] To solve the above technical problems, the present invention provides a coil stacking and winding process with interlayer insulation between double foils, which is suitable for winding the interlayer insulation strip between the upper foil strip and the lower foil strip.

[0006] Step 100: The interlayer insulation unwinding device releases the interlayer insulation tape;

[0007] Step 200: The interlayer insulation tape is fed into the interlayer insulation clamping device. After being guided by the interlayer insulation clamping device, the interlayer insulation tape is pasted onto the upper surface of the lower foil tape.

[0008] Step 300: A first guide roller (23) is arranged downstream of the interlayer insulation clamping device. The interlayer insulation strip and the lower foil strip pass through the first guide roller together and then pass through the lower shearing device together.

[0009] Step 400: After passing through the lower layer shearing device, the interlayer insulating tape and the lower layer foil tape first pass together through the rotary correction detection device, and then pass together through the lower layer roller to reach the second guide roller.

[0010] Step 500: The second guide roller separates the interlayer insulating tape and the lower foil tape. The interlayer insulating tape, the lower foil tape, and other foil tapes enter the winding device respectively to begin stacking and winding.

[0011] According to the coil stacking and winding process of adding insulation between double foils, after the interlayer insulation tape is pasted on the upper surface of the lower foil tape, the lower feeding device for conveying the lower foil tape simultaneously conveys the interlayer insulation tape and the lower foil tape.

[0012] This embodiment also provides a coil stacking and winding mechanism with interlayer insulation between double foils, which is suitable for the coil stacking and winding process with interlayer insulation between double foils. The mechanism is characterized in that, according to the conveying direction of the interlayer insulation tape, it includes an interlayer insulation unwinding device, an interlayer insulation clamping device, a first guide roller, a rotary correction detection device, and a second guide roller arranged in sequence for conveying the interlayer insulation tape.

[0013] The coil stacking and winding mechanism with interlayer insulation between double foils also includes a frame, wherein the interlayer insulation clamping device, the first guide roller, the rotary correction detection device and the second guide roller are mounted on the frame.

[0056] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0057] It should be noted that, in this invention, the top, bottom, left, and right in the figure are considered to be the top, bottom, left, and right of the coil stacking and winding mechanism with interlayer insulation between double foils described in this specification.

[0058] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to fully and completely disclose the invention and to fully convey its scope to those skilled in the art. The terminology used in the exemplary embodiments illustrated in the drawings is not intended to limit the invention. In the drawings, the same units / elements are referred to by the same reference numerals.

[0059] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning.

[0060] This embodiment relates to a coil stacking and winding process with interlayer insulation between double foils, which is suitable for winding the interlayer insulation strip B between the upper foil strip A and the lower foil strip C. The upper foil strip A is unwound and conveyed by the upper unwinding machine 11, and the lower foil strip C is unwound and conveyed by the lower unwinding machine 32. Both the upper unwinding machine 11 and the lower unwinding machine 32 are mounted on the unwinding machine base 44.

[0061] A movable material support platform 12 is provided above the upper uncoiler 11. The movable material support platform 12 can support the upper foil strip A unwound by the upper uncoiler 11. The upper foil strip A then passes through the upper shearing device 13 and the upper roller 14 in sequence. Finally, the upper foil strip A is conveyed into the winding device 41.

[0062] The lower foil strip C unwound by the lower unwinder 32 passes sequentially through the lower feeding device 33, the lower shearing device 34, the rotary correction detection device 24, and the lower roller 31. Finally, the lower foil strip C is conveyed into the winding device 41.

[0063] The end insulation roll from the end insulation device 43 is also fed into the winding device 41 to insulate both ends of the wound foil strip. Finally, the welding device can be moved to the strip roll to weld the end of the foil strip, thus completing the low-voltage coil winding.

[0064] Except for the rotary correction detection device 24, the above structures belong to the prior art.

[0065] Please see Figure 1 and combined Figure 2 The coil lamination and winding process with interlayer insulation between double foils includes:

[0066] Step 100: The interlayer insulation unwinding device 21 releases the interlayer insulation tape B.

[0067] Interlayer insulation tape B is wound on the air expansion shaft of interlayer insulation unwinding device 21. The air expansion shaft is driven to rotate by interlayer insulation unwinding device 21, thereby releasing interlayer insulation tape B.

[0068] The interlayer insulation unwinding device 21 can be installed between the upper uncoiler 11 and the lower uncoiler 32.

[0069] Step 200: The interlayer insulation tape B is conveyed into the interlayer insulation clamping device 22. After being guided by the interlayer insulation clamping device 22, the interlayer insulation tape B is pasted onto the upper surface of the lower foil tape C.

[0070] In some embodiments, after being guided by the interlayer insulation clamping device 22, the interlayer insulation tape B can be manually or using tools to adhere to the upper surface of the lower foil tape C.

[0071] The functions of the interlayer insulation clamping device 22 are: firstly, to guide the conveying direction of the interlayer insulation tape B; and secondly, to clamp the interlayer insulation tape B when the coil is completed, preventing the interlayer insulation tape B from being pulled out due to the rotation of the material roll after being cut.

[0072] Step 300: A first guide roller 23 is arranged downstream of the interlayer insulation clamping device 22. The interlayer insulation strip B and the lower foil strip C pass through the first guide roller 23 together and then pass through the lower shearing device 34 together.

[0073] Since the interlayer insulation tape B is relatively lightweight, it can be attached to the upper surface of the lower foil tape C. While the lower foil tape C is being transported, the lower foil tape C carries the interlayer insulation tape B along with it.

[0074] The first guide roller 23 is located upstream of the lower shearing device 34 and is used to guide the conveying direction of the interlayer insulation tape B to avoid collision between the interlayer insulation tape B and the pressure plate of the lower shearing device 34.

[0075] Step 400: After passing through the lower shearing device 34, the interlayer insulating tape B and the lower foil tape C first pass together through the rotary correction detection device 24, and then pass together through the lower roller 31 to reach the second guide roller 25.

[0076] In step 500, the second guide roller 25 separates the interlayer insulating tape B and the lower foil tape C. The interlayer insulating tape B, the lower foil tape C, and other foil tapes then enter the winding device 41 to begin the stacking and winding process. The other foil tapes here include at least the upper foil tape A.

[0077] On the one hand, the second guide roller 25 can guide the conveying direction of the interlayer insulation tape B; on the other hand, the second guide roller 25 separates the interlayer insulation tape B and the lower foil tape C, ensuring that the rotary correction detection device 24 is not interfered with by the interlayer insulation tape B when detecting the edge of the lower foil tape C.

[0078] After the interlayer insulating tape B is adhered to the upper surface of the lower foil tape C, the lower layer feeding device 33, used to transport the lower foil tape C, simultaneously transports the interlayer insulating tape B and the lower foil tape C. That is, the lower layer feeding device 33 is used to transport the lower foil tape C. When the interlayer insulating tape B is added, the lower layer feeding device 33 transports both the interlayer insulating tape B and the lower foil tape C simultaneously. Therefore, there is no need to add an additional feeding device for the interlayer insulating tape B.

[0079] The winding device 41 is existing technology and includes a variable frequency motor, a winding shaft, and a support assembly. The winding shaft can be equipped with coil molds of various shapes and is an important component of existing coil winding machines.

[0080] This implementation also relates to a coil stacking and winding mechanism with interlayer insulation between double foils, suitable for coil stacking and winding processes with interlayer insulation between double foils. Please refer to [link to relevant documentation]. Figure 2 According to the conveying direction of the interlayer insulation tape B, it includes an interlayer insulation unwinding device 21, an interlayer insulation clamping device 22, a first guide roller 23, a rotary correction detection device 24, and a second guide roller 25 arranged in sequence for conveying the interlayer insulation tape B.

[0081] The coil stacking and winding mechanism with interlayer insulation between double foils also includes a frame 42, wherein an interlayer insulation clamping device 22, a first guide roller 23, a rotary correction detection device 24, and a second guide roller 25 are mounted on the frame 42.

[0082] The frame 42 mentioned above is the frame of the foil winding machine itself.

[0083] Please combine Figure 2 and Figure 3 The interlayer insulation unwinding device 21 includes a column 211, an unwinding shaft assembly 212, a bracket 213, and a transverse position adjustment structure 214.

[0084] Among them, column 211 is fixed on the uncoiler base 44. Figure 3 The upper uncoiler 11 is located on the base 44 of the uncoiler. Figure 3 The support frame 111 of the upper uncoiler 11 is shown.

[0085] Please see Figure 6 The unwinding shaft assembly 212 is mounted on the column 211. The interlayer insulation tape B is wound on the unwinding shaft assembly 212. The unwinding shaft assembly 212 includes at least a mounting base and a linear guide pair 2121. The two mounting bases are respectively set on two supports 213. A rotatable unwinding shaft is erected between the two mounting bases. The bottom of each mounting base is set on the support 213 through the linear guide pair 2121 so that the unwinding shaft assembly 212 can move laterally along the axial direction on the support 213.

[0086] Both brackets 213 are fixed on the upright frame 111 of the upper uncoiler 11, and the unwinding shaft assembly 212 is slidably installed on the brackets 213.

[0087] When it is necessary to adjust the position of the unwinding shaft assembly 212, the unwinding shaft assembly 212 can be adjusted by the transverse position adjustment structure 214, so that the unwinding shaft assembly 212 slides along the linear guide pair 2121, thereby changing the position of the unwinding shaft relative to the unwinder base 44, that is, changing the fixed reference position of the interlayer insulation strip B relative to the coil winding correction detection setting.

[0088] The linear guide pair 2121 consists of a linear guide and a slider. The linear guide can be mounted on the bracket 213, and the slider can be mounted on the bottom of the mounting base. The mounting base is a unwinding shaft, on which the interlayer insulation tape B is wound. The rotation of the unwinding shaft is driven by a motor and a reducer after connection.

[0089] The lateral position adjustment structure 214 is suitable for adjusting the lateral movement distance of the unwinding shaft assembly 212 along the axial direction.

[0090] In some embodiments, the lateral position adjustment structure 214 includes a base, a lead screw, and a nut. The base is fixed to the top of the column 211; the lead screw is installed inside the base, and a handwheel is provided at one end of the lead screw; the nut is installed on the lead screw and is connected to the unwinding shaft assembly 212.

[0091] Turning the handwheel drives the lead screw to rotate, and the nut moves along the axial direction of the lead screw. The unwinding shaft assembly 212 on the nut also moves accordingly. Specifically, the unwinding shaft assembly 212 moves laterally along the axial direction of the linear guide pair 2121.

[0092] like Figure 4 As shown, the interlayer insulation clamping device 22 includes a support frame, an upper roller 221, and a lower roller 222. The support frame is mounted on the machine frame 42; the upper roller 221 is mounted on the support frame and is a fixed roller that cannot rotate but can be lifted; the lower roller 222 is mounted on the support frame and is located directly below the upper roller 221.

[0093] exist Figure 4Based on the structure shown, the interlayer insulation tape B is conveyed into the interlayer insulation clamping device 22. After being guided by the lower roller 222 in the interlayer insulation clamping device 22, the interlayer insulation tape B is manually or using tools to stick it to the upper surface of the lower foil tape C.

[0094] Please combine Figure 2 and Figure 4 The interlayer insulation clamping device 22 is mounted on the frame 42. The lower roller 222 is a rotating roller, and the upper roller 221 is a fixed roller that cannot rotate. When the upper roller 221 is pushed up, the interlayer insulation strip B, guided by the lower roller 222, can pass over the lower unwinding machine 32 and reach the top of the lower foil strip C. When the coil is completed, the upper roller 221 is pressed down to clamp the interlayer insulation strip B, preventing the interlayer insulation strip B from being carried out due to the rotation of the coil after shearing.

[0095] The first guide roller 23 is mounted on the frame 42 and is a non-powered rotating roller. The first guide roller 23 is used to guide the conveying direction of the interlayer insulation tape B to avoid collision between the interlayer insulation tape B and the pressure plate of the lower shearing device 34.

[0096] Please combine Figure 2 and Figure 5 The rotary correction detection device 24 includes a correction detection unit and a rotating unit 243.

[0097] The web correction detection unit is mounted on the crossbeam of the frame 42. The web correction detection unit includes at least a reflector 241 and a web correction sensor 242. The interlayer insulating tape B and the lower foil tape C pass through the space between the reflector 241 and the web correction sensor 242.

[0098] In some embodiments, the correction detection unit includes: two first rotating seats, a first slide rail, and an edge detector; the two first rotating seats are respectively fixed on the crossbeam of the frame 42, and a first lead screw is rotatably mounted on the two first rotating seats, with a handwheel at one end of the first lead screw; the first slide rail is fixed on the crossbeam between the two first rotating seats, and a first slide block is slidably mounted on the first slide rail, with a first nut connected to the first slide block, and the first nut cooperating with the first lead screw; the edge detector is fixed on the first nut.

[0099] The edge detector is used to detect the edge of the foil strip. The position of the edge detector can be adjusted by manually turning the handwheel to rotate the first lead screw, which in turn moves the first nut along the first slide rail. When parallel foil strips need to be wound, the edge detector can be adjusted to adapt to detecting parallel foil strips.

[0100] The edge detector consists of a reflector 241 and a correction sensor 242, which are arranged vertically.

[0101] The rotating part 243 can be a rotary cylinder, which is mounted on the first slide. The rotary cylinder can drive the reflector 241 to rotate to avoid the travel path of the interlayer insulating strip B and the lower foil strip C.

[0102] The correction sensor 242 is used to detect the edge of the foil strip and provide a correction signal; when the lower layer feeding device 33 conveys the lower layer foil strip C and the interlayer insulating strip B, the rotating part 243 (rotary cylinder) can drive the reflector 241 from Figure 5 Rotate 90 degrees forward or backward as shown to provide more space for the lower foil strip C to pass through with the interlayer insulation strip B. After the lower foil strip C and the interlayer insulation strip B are fixed in position and tensioned in the winding mold, rotate back to the original position.

[0103] The second guide roller 25 is mounted on the frame 42, close to the winding device 41. The second guide roller 25 is a non-powered rotating roller. On the one hand, the second guide roller 25 can guide the conveying direction of the interlayer insulation tape B; on the other hand, the second guide roller 25 separates the interlayer insulation tape B from the lower foil tape C, ensuring that the rotary correction detection device 24 is not disturbed when detecting the edge of the interlayer insulation tape B.

[0104] In general, after the interlayer insulation tape B on the interlayer insulation unwinding device 21 passes through the top of the lower layer uncoiler 32, it enters the interlayer insulation clamping device 22. Then, the interlayer insulation tape B is pasted onto the lower layer foil tape C conveyed by the lower layer uncoiler 32. It then follows the lower layer foil tape C through the first guide roller 23 and the lower layer shearing device 34 in sequence, and then through the rotary correction detection device 24 and the lower layer guide roller 31 to reach the winding device 41. Then, the interlayer insulation tape B pasted on the lower layer foil tape C is separated and passes through the second guide roller 25, and then passes into the winding device 41. After the lower layer foil tape C and the interlayer insulation tape B are fixed in position and tensioned on the winding mold, the detection port of the rotary correction detection device 24 is rotated to the edge of the foil tape, and then the winding begins.

[0105] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of the present invention.
