Description

Technical Field

[0001] The invention relates to the technical field of transformer manufacturing, and in particular to a shielded wire annular winding tool. Background Art

[0002] The shielding wire is composed of copper wire and insulating paper, and is used to shield the two strands in the coil of the continuous structure. Shielding wires of different specifications (width and thickness) and different lengths are used in one coil. In order to facilitate the manufacturing and transportation of shielding wire manufacturers, the lengths of shielding wires of the same specifications and different lengths are stacked together for manufacturing. Before the coil is wound, the shielding wire needs to be wrapped, cut, and insulated at the end according to the requirements of use. The shielding wire is wound into a ring shape for easy fixation, stacking, and subsequent transportation, and the end is insulated.

[0003] Conventional winding of shielded wires involves placing the shielded wires on plastic sheets for manual ring winding. The dimension between the inner and outer diameters after the ring winding is called the radial dimension. During winding, the operator fixes the start and rotation of the shielded wire with one hand, and winds the shield wire from the inside to the outside into a ring with the other hand, and finally cooperates with another operator to fix and tie it.

[0004] As the capacity and voltage level of transformer products increase, the size and length of shielded wires are also increasing, so the weight of shielded wires is also getting heavier. Therefore, for shielded wires with long length and heavy weight, when the radial dimension after winding is greater than 300mm, it will face many difficulties to measure and prepare them according to the above conventional process, which requires more operators to cooperate, and is time-consuming, labor-intensive and inefficient.

DETAILED DESCRIPTION

[0040] The invention discloses a shielding wire annular winding tool. The structural design of the shielding wire annular winding tool enables the number of operators required for shielding wire winding to be reduced, thereby improving efficiency and reducing the labor intensity of operators.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Please refer to Figure 1 , Figure 1 It is a schematic structural diagram of a shielded wire annular winding tooling disclosed in an embodiment of the present invention.

[0043] An embodiment of the present invention discloses a shielded wire annular winding tool, which includes a winding device 1, a wire end fixing device 2, a binding device 3, a wire breaking device 4 and a control device 5.

[0044] The winding device 1 includes a carrier disk 110, a winding disk 120 and a rotation drive mechanism 130. Figure 1 and Figure 2 As shown, the winding drum 120 is fixed on the carrying disk 110. The winding drum 120 and the carrying disk 110 can be an integral structure or a split structure. When the winding drum 120 and the carrying disk 110 are a split structure, the two are locked by threaded fasteners. The diameter of the winding drum 120 is smaller than the diameter of the carrying disk 110 to form a bearing surface around the winding drum 120 on the upper surface of the carrying disk 110. The driving end of the rotating drive mechanism 130 is transmission-connected to the carrying disk 110. When winding, the shielding wire is wound around the winding drum 120.

[0045] The wire end fixing device 2 is arranged on the circumferential side wall and / or the bearing surface of the winding drum 120, and the wire end fixing device 2 is used to clamp and fix the first end of the shielding wire; the binding device 3 is arranged on the bearing drum 110, and the binding device 3 is used to bind the wound shielding wire; the wire breaking device 4 is used to cut off the second end of the wound shielding wire.

[0046] The control device 5 includes a controller 510 and a number of turns detection device. The number of turns detection device is used to detect the number of turns of the driving end of the supporting disk 110 or the rotating drive mechanism 130. The signal input end of the controller 510 is communicated with the number of turns detection device. The signal output end of the controller 510 is communicated with the rotating drive mechanism 130, the wire end fixing device 2, the binding device 3 and the wire breaking device 4 respectively. The controller 510 is used to control the rotating drive mechanism 130, the wire end fixing device 2, the binding device 3 and the wire breaking device 4 to act according to preset instructions after the number of turns detection device detects that the driving end of the supporting disk 110 or the rotating drive mechanism 130 has rotated a preset number of turns.

[0047] During application, the first end of the shielding wire is placed on the wire end fixing device 2, and the second end of the shielding wire is passed through the wire breaking device 4, and then the winding instruction is input to the control device 5. The control device 5 controls the wire end fixing device 2 to clamp and fix the first end of the shielding wire according to the instruction, and then starts the rotating drive mechanism 130 of the winding device 1 to wind the shielding wire. At the same time, the number of turns detection device starts to detect the number of rotations of the supporting disk 110 or the driving end of the rotating drive mechanism 130, so as to obtain the length of the wound shielding wire. When the length of the wound shielding wire meets the preset requirements, the controller 510 controls the rotating drive mechanism 130 to stop the action, and then controls the binding device 3 to bind the wound shielding wire. After the binding is completed, the controller 510 controls the wire breaking device 4 to break the wire, thereby completing the winding of the shielding wire.

[0048] It can be seen from this that through the above-mentioned shielded wire annular winding tooling, only one operator is needed to pass one end of the shielded wire through the wire breaking device 4 and place it in the wire end fixing device 2, and then input the winding instruction to the control device 5. This can reduce the number of operators required for shielded wire winding and reduce the labor intensity of operators. In addition, compared with manual winding, it is more efficient and saves time and effort.

[0049] In the embodiment of the present invention, Figure 3 As shown, the wire end fixing device 2 includes a clamping mechanism 210 and a clamping drive mechanism 220, wherein the clamping mechanism 210 includes a clamping piece 212, a mounting seat 211 and a reset piece, the mounting seat 211 is arranged on the circumferential side wall or bearing surface of the winding drum 120, the clamping piece 212 is movably connected to the mounting seat 211, and the reset piece is arranged between the clamping piece 212 and the mounting seat 211; the clamping drive mechanism 220 is used to drive the clamping piece 212 to approach the axial side wall or bearing surface of the winding drum 120 to clamp and fix the first end of the shielded wire. It should be noted that the mounting seat 211 can be an integral structure with the winding drum 120 or the bearing drum 110, and the clamping piece 212 can also be movably built into the winding drum 120 or the bearing drum 110, so that no protruding structure will be formed on the winding drum 120 or the bearing surface. Of course, in order to make the structure simpler and easier to process, it can also be as follows Figure 3 In the illustrated embodiment, the pressing member 212 and the mounting seat 211 are externally arranged.

[0050] To further optimize the above technical solution, in an embodiment of the present invention, the above clamping drive mechanism 220 is an electromagnet, and the clamping member 212 is a ferromagnetic member. When the control device 5 receives a winding instruction, the electromagnet electrically adsorbs the clamping member 212 to clamp the wire end of the shielded wire.

[0051] As preferably, Figure 4As shown, in the embodiment of the present invention, the above-mentioned tying device 3 includes a tying base 310, a tying rail 320, a tying driving mechanism 330 and a tying belt conveying device 340, wherein the tying base 310 is arranged on the carrying plate 110, one end of the tying rail 320 is rotatably arranged on the tying base 310, the tying driving mechanism 330 is arranged between the tying base 310 and the tying rail 320, and the tying driving mechanism 330 is used to drive the tying rail 320 to move relative to the tying base 310 between the tying position and the releasing position. The tying rail 320 moves repeatedly. When the tying rail 320 is in the releasing position relative to the tying base 310, an opening is formed between the tying rail 320 and the tying base 310 for the shielded wire to enter and exit. When the tying rail 320 is in the tying position relative to the tying base 310, the tying rail 320 and the tying base 310 cooperate to form a circumferentially closed tying belt ring groove. The tying belt conveying device 340 is used to store the tying belt and release and tighten the tying belt into the tying belt ring groove when the tying rail 320 is in the tying position relative to the tying base 310, so as to tighten the shielded wire.

[0052] During application, after the binding rail 320 and the binding base 310 cooperate to form a circumferentially closed binding belt ring groove, the binding belt conveying device 340 rotates forward to convey the binding belt along the binding belt ring groove, so that one end of the binding belt bypasses the shielding wire and approaches the output position of the binding belt to form a binding ring, and then the binding belt conveying device 340 rotates reversely to tighten the binding belt so that the binding belt hugs the shielding wire, and then the binding belt is cut and the two ends of the binding belt are connected by bonding or hot melting.

[0053] like Figure 5 As shown, in an embodiment of the present invention, the above-mentioned wire breaking device 4 includes a device base 410 and a shearing drive mechanism 430, wherein the device base 410 is provided with a pad 420, and the driving end of the shearing drive mechanism 430 is provided with a blade 440, and the shearing drive mechanism 430 is used to drive the blade 440 to move toward the pad 420, so that the blade 440 cooperates with the pad 420 to cut the shielding wire.

[0054] To further optimize the above technical solution, an adjustment plate 450 is provided on the pad 420 and can move back and forth along the length direction of the pad 420 to adjust the position according to shielding wires of different specifications. When in use, the shielding wire is placed on the adjustment plate 450.

[0055] like Figure 1 As shown, the rotation number detection device is a counter 520 disposed on one side of the carrier plate 110. The counter 520 is used to detect the rotation number of the carrier plate 110 to calculate the length of the shielding wire. The calculation formula is as follows:

[0056] A=b·h

[0057] V=A·L

[0058]

[0059]

[0060] The formula for the number of coils: (round up)

[0061] Where, L is the winding length (fixed value), unit is mm; b is the shielding wire cross-sectional width, unit is mm; V is the shielding wire volume, unit is mm 3 ; H is the shielding wire cross-sectional height, unit: mm; A is the shielding wire cross-sectional area, unit: mm 2 ; S 面 is the plane area of ​​the shielded wire, in mm 2 ; r is the radius of the winding drum 120, in mm; △r is the radius increment of the shielding wire, in mm; T is the number of rotations of the carrier disk 110.

[0062] like Figure 1 As shown, in an embodiment of the present invention, the above-mentioned rotating drive mechanism 130 includes a rotating motor 131 and a reduction mechanism 132. The output shaft of the rotating motor 131 is connected to the input end of the reduction mechanism 132. The output end of the reduction mechanism 132 is connected to the rotating shaft of the carrier disk 110. The reduction mechanism 132 is a gear reduction mechanism 132. The speed range of the motor 131 is 700r / min~900r / min. According to the rated power of the motor 131, the output torque range of the rotating shaft of the winding disk 120 is determined to be 2000Nm~2900Nm.

[0063] To further optimize the above technical solution, the above-mentioned shielded wire annular winding tooling also includes a lifting device, which includes a lifting drive mechanism 6. A plurality of lifting drive mechanisms 6 are arranged at intervals along the circumference of the carrier disk 110. The driving end of the lifting drive mechanism 6 passes through the carrier disk 110 to lift the wound shielded wire. The lifting drive mechanism 6 can be a piston cylinder, such as a pneumatic cylinder or a hydraulic cylinder. The end of the piston rod of the piston cylinder away from the cylinder body is the driving end, or it can include a linear motor 131 and a driving rod. The driving rod is connected to the linear motor 131, and the end of the driving rod away from the linear motor 131 serves as the driving end of the lifting drive mechanism 6. Or it can include a rotating motor 131 and a transmission mechanism. The transmission mechanism is used to convert the rotation of the rotating motor 131 into a linear reciprocating motion. The transmission mechanism includes but is not limited to a rack and pinion mechanism, a cam connecting rod mechanism, and a screw slider mechanism.

[0064] Preferably, the above-mentioned lifting device also includes a carrying ring for carrying the shielded wire. The driving end of each lifting drive mechanism 6 passes through the carrying disk 110 and is connected to the carrying ring. The carrying surface of the carrying ring is flush with the carrying surface of the carrying disk 110 when the lifting drive mechanism 6 is in a non-lifting state. In this way, during winding, the shielded wire is located on the carrying ring. When the winding is completed and the binding and wire breaking are completed, the wire end fixing device 2 loosens the first end of the shielded wire. At this time, the driving ends of each lifting drive mechanism 6 act simultaneously to lift the carrying ring to facilitate the removal of the wound shielded wire.
