Description

Technical Field

[0001] The present invention is applied to the technical field of network transformer production, and particularly relates to a wire splitting mechanism, a four-wire winding T2 device, and a winding method. Background Art

[0002] In today's world, networks are ubiquitous. Network transformers are the main electronic components of network equipment. Traditionally, network transformers are produced manually. The manual production process includes: manually winding the T1 ring; manually tapping and twisting the T1 ring; fixing the T2 ring in a special fixture and manually winding the T2 ring.

[0003] With the advancement of technology, the winding of the T1 ring can now be automated by machines. However, before winding the T2 ring, the wire after the T1 ring is wound needs to be segmented and twisted. In the first section, multiple strands of enameled wire need to be twisted into one strand, and then the enameled wire is separated and the remaining wires are twisted again. Then the thick wire segment is wound on the T2 ring. When twisting the wires in sections, the wire ends that do not need to be twisted in the second section are prone to follow the rotation, resulting in messy wire ends and some loose ends still twisted together at the roots, thereby reducing the performance of the network transformer. At present, manual combing of the wire ends is still required before winding the T2 ring, which is inefficient and has high labor costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a wire splitting mechanism, a four-wire winding T2 device and a winding method, which have neat stranding, accurate segmentation, high efficiency, low labor cost and good winding effect for thick wires.

[0005] The technical solution adopted in the present invention is: the line-dividing mechanism includes a fixed seat, a clamping assembly and a line-dividing assembly; the line-dividing assembly includes a first cylinder, a first linear slide rail, a first slider and a pair of brush heads; the first cylinder and the first linear slide rail are both fixed on the fixed seat; the first slider is fixedly connected to the piston rod of the first cylinder; the first slider is slidably matched with the first linear slide rail; a pair of brush heads are respectively fixed on both sides of the first slider and the bristles are arranged facing each other; the clamping assembly is fixed on the fixed seat; the clamping assembly clamps the wire end and cooperates with the external twisting mechanism.

[0006] As can be seen from the above scheme, the two brush heads cooperate to brush out the enameled wire that does not need to be wound, and the bristles limit the position, preventing loose wires from rotating with it, thereby ensuring clear and neat segmentation of the stranded wire. Mechanical wire separation eliminates the need for manual handling and transfer after winding T1, effectively improving production efficiency while reducing labor costs. The provision of the first cylinder enables the two brush heads to rise and brush the loose wires upward, thereby combing them away.

[0007] A preferred solution is that the clamping assembly includes a second cylinder, a second linear slide, a second slider and a clamping cylinder, the second cylinder and the second linear slide are both fixed on the fixed seat, the second slider is fixedly connected to the piston rod of the second cylinder, the second slider is slidably fitted on the second linear slide, and the clamping cylinder is fixed on the second slider.

[0008] As can be seen from the above solution, the clamping cylinder is provided to clamp the wound T1 ring to twist the enameled wire, and the second cylinder is provided to enable the clamping cylinder to move up and down to cooperate with the brush head.

[0009] The four-wire winding T2 equipment includes a T1 winding module, a stranding mechanism and a T2 winding mechanism. The T1 winding module is connected to the stranding mechanism. The T1 winding module winds multiple strands of enameled wire on the T1 magnetic ring and makes the head and tail ends of the enameled wire different in length. The stranding mechanism twists several strands of enameled wire on the T1 magnetic ring into one strand. The stranding mechanism includes a stranding rotation assembly, a driving mechanism and the branching mechanism. The driving mechanism drives the stranding rotation assembly to approach or move away from the branching mechanism. The stranding rotation assembly includes a chuck, an opening and closing cylinder, a driving motor and a rotating seat. The chuck rotates on the rotating seat. The piston rod end of the opening and closing cylinder is connected to the actuating element of the chuck. The driving motor drives the chuck to rotate through a synchronous belt. The stranding rotation assembly cooperates with the clamping assembly to twist the enameled wire into one strand. The driving mechanism drives the stranding rotation assembly away from the clamping assembly, so that the chuck clamps the wire end with a longer length.

[0010] As can be seen from the above scheme, the T1 winding module is used to wind multiple strands of high-strength wire around the T1 ring. The twisting rotation assembly is used to drive the wire ends to rotate and cooperate with the wire splitting mechanism to achieve twisting. When the opening and closing cylinder extends, it pushes the actuating element in the chuck to open the clamping part and clamp the wire ends. The drive motor drives the chuck to rotate. The drive mechanism is a conventional linear drive mechanism, which is used to drive the rotating twisting assembly toward or away from the wire splitting mechanism to clamp wire ends of different lengths.

[0011] A preferred solution is that the T2 winding mechanism includes a magnetic ring clamping assembly, a winding assembly, a wire hook assembly and a pressing mechanism, the magnetic ring clamping assembly clamps and fixes the T2 ring to be wound, the winding assembly includes a rotating block, the rotating block performs circular motion with the magnetic ring as the center, the winding assembly passes the wire end on the T1 ring through the through hole of the T2 ring, and the rotating block drives the wire end from the bottom of the T2 ring to the upper end of the T2 ring, the pressing mechanism includes a fixed plate, a lifting cylinder, a connecting rod and a pressing roller, the lifting cylinder is fixed on the fixed plate, one end of the connecting rod is fixedly connected to the movable end of the lifting cylinder, and the pressing roller is rotatably engaged with the other end of the connecting rod, and when the rotating block rotates to above the T2 magnetic ring, the pressing roller cooperates with the rotating block to clamp the wire end.

[0012] As can be seen from the above scheme, the magnetic ring clamping assembly, the winding assembly and the wire hooking assembly are common magnetic ring winding structures. The pressing assembly is provided to limit the enameled wire to prevent it from spreading, thereby ensuring that the enameled wire can be accurately hooked and pulled through the hole of the T2 ring when hooking the wire, making the winding more accurate. The pressing roller cooperates with the rotating block to clamp the wire end, thereby preventing the wire end from being scattered. The lifting cylinder is provided to enable the pressing roller to move up and down. When the wire hooking assembly hooks the wire, the pressing roller moves upward to loosen the enameled wire, preventing the enameled wire from being broken by force.

[0013] A further preferred solution is that the fixed plate is provided with an arc guide surface that cooperates with the rotating block.

[0014] It can be seen from the above solution that the arc guide surface is provided to guide the enameled wire, thereby preventing the wire ends from being scattered.

[0015] The winding method comprises the following steps:

[0016] A. First, the T1 winding module pre-breaks the enameled wire, pre-breaking a portion of the wire in the diameter direction. Each enameled wire is pre-broken at a different location. Multiple strands of pre-broken enameled wire are then wound onto a T1 ring. After winding, the pre-broken portion is broken by pulling the enameled wire, resulting in a T1 ring with different lengths of the head and tail wires.

[0017] B. Then, an external transport mechanism transports the magnetic ring to the stranding mechanism. The clamping assembly clamps the T1 ring. The drive mechanism drives the chuck to move to the full stranding position. At this point, the chuck clamps all the wire ends to be stranded. The drive motor drives the chuck to rotate, completing the full stranding process.

[0018] C. Next, the chuck is released, and the driving mechanism drives the chuck away from the clamping assembly by a specified distance, allowing the shorter portion of the enameled wire to leave the clamping range of the chuck. The chuck is then clamped again, and the first cylinder extends to drive the pair of brushes to comb the shorter portion of the enameled wire to one side to separate it, and then the second stranding is performed;

[0019] D. After the wire stranding is completed, the T1 ring is transported to the T2 winding mechanism by an external transport mechanism, and the T2 ring to be wound is placed on the magnetic ring clamping assembly by the feeding mechanism. The winding assembly passes the stranded wire end of the T1 ring through the T2 ring, and the rotating block drives the wire end to move along the arc guide surface. When the rotating block rotates to the side of the magnetic ring, it stops moving and cooperates with the pressing roller to clamp the wire end. The wire hooking assembly extends to hook the wire end. At this time, the lifting cylinder extends to make the pressing roller rise, and then the wire hooking assembly retracts to drive the wire end through the T2 ring. Then the magnetic ring clamping assembly rotates the T2 ring by an angle, and repeats the above steps to wind the entire stranded wire segment around the T2 ring. BRIEF DESCRIPTION OF THE DRAWINGS

The piston rod end of the opening and closing cylinder is connected to the actuating element of the chuck. The driving motor drives the chuck to rotate through a synchronous belt. The stranding rotation assembly cooperates with the clamping assembly to twist the enameled wire into one strand. The driving mechanism drives the stranding rotation assembly away from the clamping assembly, so that the chuck clamps the wire end with a longer length.

[0027] The T2 winding mechanism includes a magnetic ring clamping assembly, a winding assembly, a wire hooking assembly, and a pressing mechanism.

The fixed plate 10 is provided with an arc guide surface 14 that cooperates with the rotating block.

[0028] The winding method comprises the following steps:

[0029] A. First, the T1 winding module pre-breaks the enameled wire, pre-breaking a portion of the wire in the diameter direction. Each enameled wire is pre-broken at a different location. Multiple strands of pre-broken enameled wire are then wound onto a T1 ring. After winding, the pre-broken portion is broken by pulling the enameled wire, resulting in a T1 ring with different lengths of the head and tail wires.

When the rotating block rotates to the side of the magnetic ring, it stops moving and cooperates with the pressing roller 13 to clamp the wire end. The wire hooking assembly extends to hook the wire end. At this time, the lifting cylinder 11 extends to make the pressing roller 13 rise, and then the wire hooking assembly retracts to drive the wire end through the T2 ring, and then the magnetic ring clamping assembly rotates the T2 ring by an angle, and repeats the above steps to wind the entire stranded wire segment on the T2 ring.
