[0023] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0024] It should be noted that, in the present invention, the top, bottom, left and right in the figure are regarded as the top, bottom, left and right of the coil stacking winding mechanism with double foils and layer insulation described in this specification.

[0025] The exemplary embodiments of the present invention are now described with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms used in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0026] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0027] The present embodiment relates to a coil stacking and winding process with double foil interlayer insulation, which is suitable for winding an interlayer insulation tape B between an upper foil tape A and a lower foil tape C. The upper foil tape A is unrolled and conveyed by an upper uncoiler 11, and the lower foil tape C is unrolled and conveyed by a lower uncoiler 32. Both the upper uncoiler 11 and the lower uncoiler 32 are installed on an uncoiler base 44.

[0028] A movable supporting platform 12 is provided above the upper uncoiler 11, and the movable supporting platform 12 can support the upper foil strip A unrolled by the upper uncoiler 11, and the upper foil strip A then passes through the upper shearing device 13 and the upper roller 14 in sequence, and finally, the upper foil strip A is transported into the winding device 41.

[0029] The lower foil strip C unrolled by the lower uncoiler 32 passes through the lower feeding device 33, the lower shearing device 34, the rotary deviation correction detection device 24 and the lower roller 31 in sequence, and finally, the lower foil strip C is transported into the winding device 41.

[0030] The end insulation roll from the end insulation device 43 is also passed into the winding device 41 to insulate the two ends of the wound tube foil tape. Finally, the welding device can be moved to the tape roll to weld the end of the tube foil tape, and finally the low-voltage coil winding is completed.

[0031] Except for the rotary deviation correction detection device 24, the above structures belong to the prior art.

[0032] See also Figure 1 , and combined with Figure 2 The coil stacking process with double foil insulation includes: Step 100 : the interlayer insulation unwinding device 21 unwinds the interlayer insulation tape B.

[0033] The interlayer insulation tape B is wound on the air expansion shaft of the interlayer insulation unwinding device 21 , and the interlayer insulation unwinding device 21 drives the air expansion shaft to rotate, thereby unwinding the interlayer insulation tape B.

[0034] The interlayer insulation unwinding device 21 may be disposed between the upper layer unwinding machine 11 and the lower layer unwinding machine 32 .

[0035] Step 200 , the interlayer insulation tape B is transported into the interlayer insulation clamping device 22 , and after being guided by the interlayer insulation clamping device 22 , the interlayer insulation tape B is adhered to the upper surface of the lower foil tape C.

[0036] In some embodiments, after being guided by the interlayer insulation clamping device 22, the interlayer insulation tape B can be attached to the upper surface of the lower foil tape C manually or using a tool.

[0037] The first function of the interlayer insulation clamping device 22 is to guide the conveying direction of the interlayer insulation tape B. The second function is that when the coil is completed, the interlayer insulation clamping device 22 clamps the interlayer insulation tape B to prevent the interlayer insulation tape B from being carried out due to the rotation of the material roll after cutting.

[0038] Step 300 , a first guide roller 23 is arranged downstream of the interlayer insulation clamping device 22 , and the interlayer insulation tape B and the lower layer foil tape C pass through the first guide roller 23 together and then pass through the lower layer shearing device 34 together.

[0039] Since the interlayer insulating tape B is light in weight, the interlayer insulating tape B can be pasted on the upper surface of the lower foil tape C. When the lower foil tape C is conveyed, the lower foil tape C carries the interlayer insulating tape B forward together.

[0040] The first guide roller 23 is arranged upstream of the lower shearing device 34 and is used to guide the conveying direction of the interlayer insulating tape B to prevent the interlayer insulating tape B from colliding with the pressure plate of the lower shearing device 34 .

[0041] Step 400 , after passing through the lower layer shearing device 34 , the interlayer insulating tape B and the lower layer foil tape C first pass through the rotary deviation correction detection device 24 together, and then pass through the lower layer passing roller 31 together before reaching the second guide roller 25 .

[0042] Step 500, the second guide roller 25 separates the interlayer insulation tape B and the lower foil tape C, and the interlayer insulation tape B, the lower foil tape C and other foil tapes enter the winding device 41 respectively to start the stacking winding. The other foil tapes here include at least the upper foil tape A.

[0043] On the one hand, the second guide roller 25 can guide the conveying direction of the interlayer insulating tape B; on the other hand, the second guide roller 25 separates the interlayer insulating tape B and the lower foil tape C, ensuring that the rotary deviation correction detection device 24 is not disturbed by the interlayer insulating tape B when detecting the edge of the lower foil tape C.

[0044] After the interlayer insulation tape B is pasted on the upper surface of the lower foil tape C, the lower layer feeding device 33 for conveying the lower foil tape C simultaneously conveys the interlayer insulation tape B and the lower foil tape C. That is, the lower layer feeding device 33 is used to convey the lower foil tape C. After the interlayer insulation tape B is added, the lower layer feeding device 33 simultaneously conveys the interlayer insulation tape B and the lower foil tape C. Therefore, there is no need to add an additional feeding device for the interlayer insulation tape B.

[0045] The winding device 41 belongs to the prior art, and comprises a variable frequency motor, a winding shaft, and a supporting assembly. The winding shaft thereon can be installed with coil molds of various shapes, and is an important component of the existing coil winding machine.

[0046] This embodiment also relates to a coil stacking winding mechanism with double foils and an additional layer of insulation, which is suitable for a coil stacking winding process with double foils and an additional layer of insulation. Figure 2 According to the conveying direction of the interlayer insulating tape B, it includes an interlayer insulating unwinding device 21, an interlayer insulating clamping device 22, a first guide roller 23, a rotary deviation correction detection device 24 and a second guide roller 25 which are arranged in sequence for conveying the interlayer insulating tape B.

[0047] The coil stacking winding mechanism with double foil interlayer insulation also includes a frame 42 , wherein the interlayer insulation clamping device 22 , the first guide roller 23 , the rotary deviation correction detection device 24 and the second guide roller 25 are mounted on the frame 42 .

[0048] The frame 42 mentioned above is the frame of the foil winding machine itself.

[0049] 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 lateral position adjustment structure 214.

[0050] The column 211 is fixed on the uncoiler base 44. Figure 3 The upper uncoiler 11 is located on the middle uncoiler base 44. Figure 3 The stand 111 of the upper decoiler 11 is shown.

[0051] See also Figure 6 The unwinding shaft assembly 212 is installed on the column 211, and the interlayer insulating tape B is wound on the unwinding shaft assembly 212. The unwinding shaft assembly 212 at least includes a mounting seat and a linear guide pair 2121. The two mounting seats are respectively arranged on two brackets 213, and a rotatable unwinding shaft is mounted between the two mounting seats; the base of each mounting seat is arranged on the bracket 213 through the linear guide pair 2121, so that the unwinding shaft assembly 212 can move horizontally along the axial direction on the bracket 213.

[0052] The two brackets 213 are both fixed on the stand 111 of the upper uncoiler 11 , and the unwinding shaft assembly 212 is slidably mounted on the brackets 213 .

[0053] When the position of the unwinding shaft assembly 212 needs to be adjusted, 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 uncoiler base 44, that is, changing the fixed reference position of the interlayer insulating tape B relative to the coil winding deviation correction detection setting.

[0054] The linear guide pair 2121 consists of a linear guide and a slider. The linear guide can be installed on the bracket 213, and the slider can be installed on the bottom of the mounting seat. The mounting seat is the unwinding shaft, and the interlayer insulating tape B is wound on the unwinding shaft. The rotation of the unwinding shaft is driven by the motor and the reducer after being connected.

[0055] The lateral position adjustment structure 214 is suitable for adjusting the lateral displacement distance of the unwinding shaft assembly 212 along the axial direction.

[0056] 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 in the base, and a hand wheel is provided at one end of the lead screw; the nut is installed on the lead screw, and the nut is connected to the unwinding shaft assembly 212.

[0057] The hand wheel is turned to drive the lead screw to rotate, and the nut moves along the axial direction of the lead screw, and the unwinding shaft assembly 212 on the nut also moves accordingly. Specifically, the unwinding shaft assembly 212 moves laterally along the axial direction along the linear guide pair 2121.

[0058] 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 frame 42; the upper roller 221 is mounted on the support frame, and the upper roller 221 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.

[0059] exist Figure 4 Based on the structure shown, the interlayer insulation tape B is transported into the interlayer insulation clamping device 22, and 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 to the upper surface of the lower foil tape C.

[0060] Please combine Figure 2 and Figure 4 The interlayer insulation clamping device 22 is integrally 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 and lifted, the interlayer insulation tape B can pass through the lower layer unwinder 32 and reach the upper surface of the lower layer foil tape C under the guidance of the lower roller 222. When the coil is completed, the upper roller 221 is pressed down to clamp the interlayer insulation tape B to prevent the interlayer insulation tape B from being taken out due to the rotation of the material roll after cutting.

[0061] 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 insulating tape B to prevent the interlayer insulating tape B from colliding with the pressing plate of the lower shearing device 34.

[0062] Please combine Figure 2 and Figure 5The rotary deviation correction detection device 24 includes a deviation correction detection unit and a rotation unit 243 .

[0063] The deflection correction detection unit is installed on the crossbeam of the frame 42 , and the deflection correction detection unit at least includes a reflector 241 and a deflection correction sensor 242 . The interlayer insulation tape B and the lower foil tape C pass through between the reflector 241 and the deflection correction sensor 242 .

[0064] In some embodiments, the deviation 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 cross beam of the frame 42, and the two first rotating seats are rotatably provided with a first screw rod, and a hand wheel is provided at one end of the first screw rod; the first slide rail is fixed on the cross beam between the two first rotating seats, and the first slide rail is slidably equipped with a first slide seat, and the first slide seat is connected with a first nut, and the first nut cooperates with the first screw rod; the edge detector is fixed on the first nut.

[0065] The edge detector is used to detect the edge of the foil. The first lead screw can be rotated by manually turning the hand wheel, thereby driving the first nut to move along the first slide rail to adjust the position of the edge detector. When the foils need to be wound in parallel, the edge detector can be adjusted to adapt to the detection of the parallel foils.

[0066] The edge detector is composed of a reflector 241 and a deviation correction sensor 242, which are arranged one above the other.

[0067] The rotating part 243 may be a rotary cylinder installed on the first slide seat. The rotary cylinder can drive the reflector 241 to rotate to avoid the travel path of the interlayer insulation tape B and the lower foil tape C.

[0068] The deflection correction sensor 242 is used to detect the edge of the foil and provide a deflection correction signal; when the lower feeding device 33 conveys the lower foil C and the interlayer insulation tape B, the rotating part 243 (rotating cylinder) can drive the reflector 241 to move from Figure 5 The position shown is rotated 90 degrees forward or reversely to provide a larger space for the lower foil tape C to pass through with the interlayer insulation tape B. The lower foil tape C and the interlayer insulation tape B are rotated back to their original positions after being fixed in position and tensioned by the winding mold.

[0069] The second guide roller 25 is installed 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 insulating tape B; on the other hand, the second guide roller 25 separates the interlayer insulating tape B from the lower foil tape C, ensuring that the rotary deviation correction detection device 24 is not disturbed when detecting the edge of the interlayer insulating tape B.

[0070] In general, the interlayer insulation tape B on the interlayer insulation unwinding device 21 enters the interlayer insulation clamping device 22 after passing through the top of the lower uncoiler 32, and then the interlayer insulation tape B is pasted on the lower foil tape C conveyed by the lower uncoiler 32, and then follows the lower foil tape C to pass through the first guide roller 23 and the lower shearing device 34 in sequence, and then passes through the rotary deviation correction detection device 24 and the lower roller 31 to reach the winding device 41, and then the interlayer insulation tape B pasted on the lower foil tape C is separated and passed through the second guide roller 25, and then inserted into the winding device 41; after the lower foil tape C and the interlayer insulation tape B are fixed in position on the winding mold and tensioned, the detection port of the rotary deviation correction detection device 24 is controlled to rotate to the edge of the foil tape, and then the winding is started.

[0071] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
