Description

Technical Field

[0001] The utility model relates to a device for automatically removing the protective paper of transposed wire when winding a transformer coil, belonging to the technical field of special equipment for transformer manufacturing. Background Art

[0002] With the continuous optimization of the structure of transformer products, coils wound with transposed wire are becoming more and more popular in transformer products. Some products use coils wound with transposed wire. The outer layer of the transposed wire conductor is provided with protective paper, such as Chinese patents CN201110398780.6 named "Mesh-wrapped transposed conductor with local insulation protection layer" and CN201610499879.8 named "Packaging of a single transposed wire", etc. During the winding process of the transformer coil, it is necessary to remove the protective paper of the transposed wire while winding the coil. There is a nylon rope inside the protective paper of the transposed wire as a cable. Pulling this cable can remove the protective paper. However, the existing technology does not have a device for removing the protective paper when winding a transformer coil with transposed wire. It can only remove the protective paper of the transposed wire by manually pulling the nylon rope, which requires human and material resources and has a certain impact on the coil winding efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a device for automatically removing the protective paper of transposed wire when winding a transformer coil, which automatically pulls the cable of the protective paper of the transposed wire, automatically removes the protective paper on the outer layer of the transposed wire, saves human and material resources, improves the winding efficiency of the transformer coil, reduces the production cost, and solves the above technical problems existing in the existing technology.

[0004] The technical solution of the utility model is as follows:

[0005] A device for automatically removing the protective paper of transposed wire when winding a transformer coil includes a wire arranging device, a cable controller and a cable winding system. The wire arranging device consists of a mounting rod, fastening bolts, longitudinal beams, limiting plates, transverse limiting rods, longitudinal limiting rods and a mounting base plate. The mounting rod is a horizontally arranged cross beam. The tops of the two longitudinal beams are respectively connected to the mounting rod through fastening bolts. The longitudinal beams are vertically arranged. The bottoms of the two longitudinal beams are fixed on the mounting base plate. The mounting rod, the mounting base plate and the two longitudinal beams together form a rectangular frame. Two limiting plates are respectively fixed on the inner sides of the two longitudinal beams. The limiting plates are provided with a plurality of grooves. The number and positions of the grooves on the two limiting plates are the same and correspond to each other. The number of transverse limiting rods is multiple, and the two ends are respectively placed in the corresponding grooves of the two limiting plates. Two vertically arranged longitudinal limiting rods are arranged inside the rectangular frame. The two ends of the longitudinal limiting rods are respectively fixed on the mounting rod and the mounting base plate. Multiple transverse limiting rods and the two longitudinal limiting rods are arranged crosswise in the rectangular frame, forming a plurality of rectangular through holes surrounded by the transverse limiting rods and the longitudinal limiting rods inside the two longitudinal limiting rods. The transposed wire passes through the rectangular through holes.

[0006] The cable controller and the winding system are arranged on the mounting plate below the mounting rod. The cable controller consists of a front cable limit, a control connecting rod, a micro switch and a rear cable limit mounted on the mounting plate. The front cable limit and the rear cable limit are respectively arranged at the front end and the rear end of the control connecting rod, and the control connecting rod is matched with the micro switch. The number of cable controllers is multiple sets, which is matched with the number of transposition wires. The cable winding system includes a motor, a bearing seat and a winding shaft mounted on the mounting plate. The output shaft of the motor is the winding shaft, and the winding shaft is mounted in the bearing seat. The number of cable winding systems is matched with the number of cable controllers. The cable of the transposition wire passes through the front cable limit and the rear cable limit and then winds around the winding shaft. The transposition wire cable between the front cable limit and the rear cable limit presses the control connecting rod to touch the micro switch, thereby controlling the start and stop of the motor, pulling the cable to tear the protective paper of the transposition wire, the protective paper detaches from the transposition wire, and the transposition wire after the protective paper falls off enters the winding machine to wind the transformer coil.

[0007] Further, an electric control system is also provided on the mounting plate. The main body of the electric control box of the electric control system is mounted on the mounting plate. A sub-control selection switch, a main switch button and an emergency stop button are arranged in the main body of the electric control box. The sub-control selection switch is used to select the motor for work, and the arrangement number of the sub-control selection switch corresponds to the number of transposition wires required for coil winding. The main switch button is the main control switch of the power supply. The emergency stop button is an emergency button for sudden situations.

[0008] Further, bearings are respectively arranged at both ends of the horizontal limiting rod, and the horizontal limiting rod rotates freely in the bearings, which is convenient for the transposition wire to pass through the rectangular through hole without damaging the transposition wire.

[0009] Further, the winding shaft is provided with a relief groove; the relief groove on the winding shaft is convenient for removing the wound cable.

[0010] Further, the mounting rod is used to install the wire arranging device on the wire reel rack, and the wire reel rack places the mesh-wrapped transposition wire shaft (the transposition wires are all wound on the axle). The groove on the limiting plate is used to limit the position of the horizontal limiting rod and facilitate the disassembly of the horizontal limiting rod. The horizontal limiting rod separates the transposition wires longitudinally without interference. The longitudinal limiting rod is used to limit the position of the transposition wires left and right, so that the transposition wires are separated transversely without interference.

[0011] Further, the micro switch is a travel switch with a 24V safety voltage, which controls the on and off of the motor power supply during use; the control connecting rod is the trigger of the micro switch; the front cable limit and the rear cable limit can conveniently introduce and lead out the cable of the transposition wire, and at the same time tension the cable to press the control connecting rod.

[0012] Further, the front cable limit and the rear cable limit are of an open annular structure, and the cable is put in from the opening.

[0013] Further, the front cable stopper is installed on the mounting bracket, and the mounting bracket is installed on the mounting plate.

[0014] The transposed wire is led out from the wire spool on the wire spool rack and passes through the rectangular through hole on the wire arranging device; a part of the cable is pulled out from the transposed wire protection paper, and after passing through the front cable stopper and the rear cable stopper of the cable controller, it is fixed to the winding shaft of the cable winding system; the transposed wire after the cable pulling protection paper falls off enters the die of the winding machine; the corresponding motors of the winding machine and the cable winding system are started. The winding machine pulls the transposed wire to drive the wire spool on the wire spool rack to rotate and pay out the wire, and the motor drives the winding shaft to rotate to wind the cable on the winding shaft. After the cable tears the transposed wire protection paper and cracks and falls off, the transposed wire winds the transformer coil on the die of the winding machine.

[0015] The cable presses the control link through the front cable stopper and the rear cable stopper. The control link touches the microswitch, and the power supply of the motor is turned on, automatically removing the protection paper of the transposed wire; when the winding machine stops rotating and other operations are required for coil winding, the wire spool on the wire spool rack also stops rotating, the transposed wire does not move, and the motor continues to rotate to wind the cable. When the position of the cable reaches a certain angle, the control link is touched, the microswitch acts, automatically cutting off the power supply of the motor, and the motor stops rotating and no longer winds the cable, so the protection paper of the transposed wire is no longer automatically removed. When the winding machine continues to rotate and the coil is normally wound, the transposed wire continues to move forward, the cable moves forward synchronously, the pressure on the control link is reduced, the motor is connected, and the winding shaft rotates to continue winding the cable, causing the protection paper of the transposed wire to fall off. This process is repeated continuously according to the coil winding situation until the coil winding is completed. At this time, the wound cable is taken off through the relief groove on the winding shaft, and a new wire spool on the wire spool rack is replaced to continue winding the wire.

[0016] Further, the number of wire spools on the wire spool rack is multiple, and the transposed wires on the wire spools respectively pass through multiple rectangular through holes on the wire arranging device, and the cables of each transposed wire are respectively wound on their own winding shafts.

[0017] Further, the power of the motor is matched with the breaking force of the cable. By controlling the control link through the different angular positions of the cable, the start and stop of the motor are effectively controlled, and at the same time, the cable will not be broken.

[0018] The positive effects of the present utility model: The cable automatically pulls the protection paper of the transposed wire, automatically removing the outer protection paper of the transposed wire, saving manpower and material resources, and improving the winding efficiency of the transformer coil; during the process of winding the coil with the transposed wire, the present utility model can effectively save an auxiliary wire arranging personnel and reduce the coil manufacturing cost.

The longitudinal beams 3 are vertically arranged, and the bottoms of the two longitudinal beams 3 are fixed on the mounting base plate 7. The mounting rod 1, the mounting base plate 7, and the two longitudinal beams 3 together form a rectangular frame. Two limiting plates 4 are respectively fixed on the inner sides of the two longitudinal beams 3. The limiting plates 4 are provided with a plurality of grooves 21. The number and positions of the grooves on the two limiting plates 4 are the same and correspond to each other. The number of transverse limiting rods 5 is multiple, and the two ends are respectively placed in the corresponding grooves of the two limiting plates. Two vertically arranged longitudinal limiting rods 6 are arranged inside the rectangular frame. The two ends of the longitudinal limiting rods 6 are respectively fixed on the mounting rod 1 and the mounting base plate 7.

The transposed wire passes through the rectangular through holes 22.

[0029] Refer to the appendix Figures 2 - 5 , The cable controller and the winding system are arranged on the mounting plate 13 below the mounting rod 1. The cable controller consists of a cable front limit 8, a control connecting rod 9, a microswitch 10, and a cable rear limit 11 mounted on the mounting plate 13. The cable front limit 8 and the cable rear limit 11 are respectively arranged at the front end and the rear end of the control connecting rod 9.

The output shaft of the motor 12 is the winding shaft 15, and the winding shaft 15 is mounted in the bearing seat 14. The number of cable winding systems matches the number of cable controllers. The cable of the transposed wire passes through the cable front limit 8 and the cable rear limit 11 and then winds around the winding shaft 15. The transposed wire cable between the cable front limit 8 and the cable rear limit 11 presses the control connecting rod 9 to touch the microswitch 10, thereby controlling the start and stop of the motor 12, and pulling the cable to tear the protective paper of the transposed wire. The protective paper detaches from the transposed wire, and the transposed wire after the protective paper falls off enters the winding machine 29 to wind the transformer coil 30.

[0030] Refer to the appendix Figure 2 and 6, an electric control system is also provided on the mounting plate 13. The main body 16 of the electric control box of the electric control system is installed on the mounting plate 13. A sub-control selection switch 17, a main switch button 18 and an emergency stop button 19 are provided inside the main body 16 of the electric control box. The sub-control selection switch 17 is used to select the motor for operation, and the number of sub-control selection switches 17 arranged corresponds to the number of transposed wires required for coil winding; the main switch button 18 is the main control switch of the power supply; the emergency stop button 19 is an emergency button for emergencies.

[0031] Refer to the appendix Figure 1 , bearings 23 are respectively provided at both ends of the horizontal limiting rod 5. The horizontal limiting rod 5 rotates freely within the bearings, facilitating the passage of the transposed wire through the rectangular through-hole 22 without damaging the transposed wire.

[0032] Refer to the appendix Figure 2 , a relief groove 24 is provided on the winding shaft 15; the relief groove 24 on the winding shaft facilitates the removal of the wound cable.

[0033] The mounting rod 1 is used to mount the wire arranging device onto the wire reel rack 25. The wire reel rack 25 holds the mesh-wrapped transposed wire spool 26 (the transposed wires are all wound around the axle); the groove on the limiting plate 4 is used to limit the position of the horizontal limiting rod and facilitate the disassembly of the horizontal limiting rod; the horizontal limiting rod 5 separates the transposed wires longitudinally without interference; the longitudinal limiting rod 6 is used to limit the left and right positions of the transposed wires, separating the transposed wires transversely without interference.

[0034] The microswitch 10 is a travel switch with a 24V safety voltage, controlling the on-off of the motor power supply during use; the control link 9 is the trigger of the microswitch; the front cable limit 8 and the rear cable limit 11 can facilitate the introduction and extraction of the cable of the transposed wire, and at the same time, the tensioned cable presses the control link 9.

[0035] Refer to the appendix Figure 4 , the front cable limit 8 and the rear cable limit 11 are of an open-ring structure, and the cable is placed through the opening.

[0036] Refer to the appendix Figure 2 , the front cable limit 8 is installed on the mounting bracket 31, and the mounting bracket 31 is installed on the mounting plate 13.

[0037] The transposed wire is led out from the wire spool 26 of the wire spool rack 25 and passes through the rectangular through-hole 22 on the wire arranging device; a part of the cable 27 inside the transposed wire protection paper is torn out, and after passing through the front cable limit 8 and the rear cable limit 11 of the cable controller, it is fixed to the winding shaft 15 of the cable winding system; the transposed wire 20 after the cable 27 tears off the protection paper 28 enters the die of the winding machine 29; the corresponding motors 12 of the winding machine and the cable winding system are started. The winding machine pulls the transposed wire to drive the wire spool 26 of the wire spool to rotate and pay out the wire. The motor 12 drives the winding shaft 15 to rotate to wind the cable around the winding shaft 15. After the cable tears the transposed wire protection paper and cracks and falls off, the transposed wire winds the transformer coil 30 on the die of the winding machine 29.

[0038] The cable presses the control link 9 through the front cable limit 8 and the rear cable limit 11. The control link 9 touches the microswitch 10, and the power supply of the motor 12 is turned on, automatically removing the protection paper 28 of the transposed wire; when the winding machine 29 stops rotating and other operations are required for coil winding, the wire spool 26 of the wire spool also stops rotating, the transposed wire does not move, and the motor 12 continues to rotate to wind the cable. When the position of the cable reaches a certain angle, the control link 9 is touched, the microswitch 10 acts, and the power supply of the motor 12 is automatically cut off, and the motor stops rotating and no longer winds the cable, so the transposed wire protection paper is no longer automatically removed. When the winding machine 29 continues to rotate and the coil is normally wound, the transposed wire continues to move forward, the cable moves forward synchronously, the pressure on the control link 9 is reduced, the motor is connected, and the winding shaft rotates to continue winding the cable, causing the transposed wire protection paper to fall off. This process is continuously repeated according to the coil winding situation until the coil winding is completed. At this time, the wound cable is taken off through the relief groove 24 on the winding shaft, and a new wire spool 26 of the wire spool is replaced to continue winding the wire.

[0039] The number of wire spools 26 of the wire spool on the wire spool rack is multiple. The transposed wires on the wire spools 26 respectively pass through multiple rectangular through-holes 22 on the wire arranging device, and the cables of each transposed wire are respectively wound on their own winding shafts 15.

[0040] The power of the motor 12 is matched with the breaking force of the cable. By controlling the touch of the control link 9 through the different angular positions of the cable, the start and stop of the motor are effectively controlled, and at the same time, the cable will not be broken.

[0041] One rectangular through-hole 22 can pass through one transposed wire or multiple transposed wires.

[0042] The wire arranging device is a set of detachable / fixed transposed wire separating devices, which are used to limit the relative positions of the transposed wires, ensure that the parallel transposed wires pass smoothly without damaging the wires, and at the same time limit the relative positions of the transposed wires, the cable controller and the cable winding system, facilitating the automatic control of the rotation and stop of the motor.

[0043] The number of cable controllers and cable winding systems is determined according to the number of parallel strands of transposed wires required for winding the transformer coil. In the embodiment, 3 transposed wires are wound in parallel, and 3 sets of cable controllers and cable winding systems are used. Each set of cable controllers and cable winding systems controls the start and stop of a motor, thereby controlling the cable winding to ensure that the progress of removing the protection paper of the transposed wire is consistent with the progress of the transposed wire required for coil winding. The cable controllers and cable winding systems ensure that the cable has a certain strength to tear the protection paper, and at the same time facilitate the collection of the cable and the unified removal. During the process of winding the coil with transposed wires, one auxiliary wire arranging person can be effectively saved, the coil winding efficiency can be improved, and the coil manufacturing cost can be reduced.

[0044] The transverse limiting rod 5 and the longitudinal limiting rod 6 are made of insulating materials. The two ends of the transverse limiting rod 5 are provided with bearings and can roll freely. After being processed by the wire arranging device, the transposed wires (electromagnetic wires) are fixed in position relative to each other and do not interfere with each other. A part of the cable (nylon material) inside the protection paper of one transposed wire can be manually pulled out, fed into the cable front limiter, passed through the control connecting rod, and then fixed to the winding shaft after passing through the cable rear limiter. The sub-control selection switch of the corresponding motor of the electric control system is turned on, and the parallel winding of the transposed wires is completed in sequence. The protection paper of each transposed wire automatically removes the outer protection paper of the transposed wire according to the requirements of coil winding, without the need for manual auxiliary interference until the coil winding is completed, effectively achieving the same demand, thereby improving the coil winding efficiency and reducing the coil manufacturing cost.
