Description

Technical Field

[0001] This invention relates to an electrical device, and more specifically, to an automatic current transformer storage ring device and its operating method. Background Technology

[0002] A current transformer is a device that converts a large current on a high-voltage line into a low-voltage, measurable current. Currently, both domestic and international current transformer coils consist of an iron core, insulation, and copper wire. When the coil is loaded onto the storage ring, the copper wire is piled on the ground. During the output phase, the copper wire easily rubs against the baffle, causing wear and compromising product safety. The copper wire also curls during output, resulting in uneven output. Furthermore, multi-strand windings are prone to tangling during loading. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an automatic wire storage device for current transformer wire storage rings and its working method, which can simultaneously perform multiple sets of copper wire winding, has high winding efficiency, and can automatically adjust the winding position.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic wire storage device for a current transformer wire storage ring, comprising a mounting base, with support frames at both ends of the mounting base, and a plurality of wire storage structures uniformly arranged along the height direction of the support frames. Each wire storage structure includes a support rod and a driving component disposed at both ends of the support rod. The driving component is configured to drive the support rod to rotate and to wind and store the copper wire on the support rod.

[0005] The present invention is further configured such that: the drive assembly includes a baffle disposed on the support frame, a drive bracket disposed on the baffle, and a drive bearing disposed on the drive bracket, wherein the drive bracket and the drive bearing are configured as multiple and are symmetrically arranged about the support rod as the axis.

[0006] Preferably, the drive bearing is disposed at both ends of the support rod, and a stop block is provided on the side of the drive bearing near the middle of the support rod. The stop block is configured to prevent the copper wire from getting tangled with the drive bearing during the winding process.

[0007] The present invention is further configured such that: the support frame has support rods symmetrically arranged along the central axis of the mounting base, the support rods being welded to the mounting base to form a triangular support structure oppositely arranged on both sides of the mounting base.

[0008] Preferably, the wire storage structure is fixedly connected to the support rod by welding a baffle to the support rod, and the support rod of the wire storage structure is parallel to the central axis of the mounting base.

[0009] Preferably, the support rod is further provided with an axial drive component, which includes a clutch module disposed on the support frame and connected to the drive bearings. The clutch module is used to control the relative approach / distance of each drive bearing from the support rod. Each drive bearing is provided with helical teeth, and the support frame is provided with tooth grooves corresponding to the helical teeth. The helical teeth of the drive bearings at both ends of the mounting base and the tooth grooves of the support frame face opposite directions.

[0010] This application also discloses a working method of an automatic wire storage device for a current transformer wire storage ring, including the following steps: S1, based on the number of copper wires to be wound, place a corresponding number of winding reels on the support frame; S2. Connect the starting end of the copper wire to one end of the winding reel and start the equipment to wind the wire; S3. Based on the position of the support rod, the clutch module of the axial drive unit controls the drive bearing on the corresponding side to move closer to the support rod and the drive bearing on the other side to move away from the support rod. At the same time, each drive bearing rotates at a fixed speed, driving the support rod and the winding reel to rotate while sliding in the axial direction. S4. During the lateral movement of the support rod, the position of the support rod is detected. If the support rod reaches the end position on one side of its movement direction, it is determined that the current copper wire is wound to one end of the winding reel, and jumps to S5 to perform the reversal operation. Otherwise, the corresponding drive bearing continues to drive the support rod to move. S5, the clutch module of the axial drive unit adjusts the drive bearings, so that the drive bearings that were originally close to the support rod are moved away from the support rod, and the drive bearings that were far away from the support rod are moved closer to the support rod. During the adjustment process, each drive bearing is kept rotating at a constant speed, and then jumps back to S4 to cycle.

[0011] By adopting the above technical solution, the following beneficial effects are achieved: 1. This application, by setting multiple wire storage structures at different heights, enables the simultaneous winding of multiple sets of copper wires, effectively improving production efficiency. Simultaneously, by setting axial drive components on each wire storage structure, the clutch module of the axial drive component can automatically control the connection between the drive bearing and the support rod. While achieving circumferential rotation of the support rod, lateral displacement during rotation is achieved through helical teeth and tooth grooves. The direction of movement is adjusted by changing the drive bearings that are connected to the support rod. Furthermore, during adjustment, each drive bearing rotates at a uniform speed. The mechanism ensures proper engagement of the helical teeth and grooves when the drive bearings and support rods are in contact, preventing damage caused by collisions. This structural design allows the support rod to rotate while simultaneously achieving uniform reciprocating motion in the left and right directions, ensuring even winding of the copper wire on the winding reel. It also enables automatic wire arrangement during the winding process, comprehensively solving several inherent technical problems in traditional processes, such as easy wear of copper wire, uneven wire winding, and easy tangling of multiple strands. This represents a qualitative leap from simple "winding" to intelligent "wire arrangement," ensuring high quality and high reliability in the winding process.

[0012] 2. Furthermore, the wire storage structure of this application sets the copper wire winding range within a regular space composed of the support rod, the baffle block, and the drive bearing. The copper wire no longer rubs against the external rough baffle or other components, fundamentally avoiding damage to the insulation layer and ensuring the electrical safety performance of the final current transformer. At the same time, the conversion of the winding direction is achieved by detecting the position of the winding reel, ensuring that the copper wire can be arranged neatly in layers, ensuring uniform tension during subsequent wire output, eliminating the problem of copper wire curling and wire output jamming caused by disordered accumulation, making the entire wire feeding and winding process exceptionally smooth, and improving the stability of the wound product in the production process.

[0013] 3. Simultaneously, in order to achieve the winding of multiple sets of copper wires at the same time, this application forms a three-dimensional, high-density winding structure by uniformly setting several wire storage structures along the height direction of the support frame. Each winding structure is driven independently and can process multiple sets of copper wires simultaneously without interference. The winding efficiency is high. The automatic axial movement function of each support rod ensures that each wire can be regularly arranged back and forth within its independent axial stroke. The movement paths between them are strictly limited, which completely solves the tricky problem of mutual crossing and entanglement that easily occurs when multiple wires are on the same workstation. This maximizes the production capacity within a limited floor space.

[0014] 4. Furthermore, the drive section of this application transmits driving force through drive bearings and achieves axial movement during rotation by setting helical teeth. A clutch module controls the alternating engagement and disengagement of the drive bearings at both ends with the support rod. Simultaneously, the direction of axial movement is changed by helical teeth arranged in opposite directions on the surfaces of the drive bearings at both ends of the mounting base. Specifically, the drive bearings all rotate clockwise, but the left drive bearing has left-handed helical teeth, and the right drive bearing has right-handed helical teeth. When the left drive bearing engages with the support rod and the right drive bearing disengages, the left drive bearing drives the support rod to rotate and move laterally in one direction. Conversely, when the left drive bearing disengages from the support rod and the right drive bearing engages, the right drive bearing drives the support rod to rotate and move laterally in another direction. As an optimization, the bottom of the support rod can be equipped with freely rotating helical teeth to support and guide the support rod. The entire process only requires controlling the clutch state switching to achieve automatic reversal, eliminating the need for complex independent servo control of axial movement, reducing system cost and failure rate, and exhibiting higher reliability and ease of maintenance in long-term continuous industrial environments.

[0022] The support frame 2 has support rods 21 symmetrically arranged along the central axis of the mounting base 1. The support rods 21 are welded to the mounting base 1 to form a triangular support structure that is arranged opposite to each other on both sides of the mounting base 1.

[0023] Preferably, the wire storage structure 3 is fixedly connected to the support rod 21 by welding the baffle 321 to the support rod 21, and the support rod 31 of the wire storage structure 3 is parallel to the central axis of the mounting base 1.

[0024] Preferably, the support rod 31 is further provided with an axial drive component 4. The axial drive component 4 includes a clutch module 41 disposed on the support frame 2 and connected to the drive bearing 323. The clutch module 41 is used to control the relative approach / away from the support rod 31 of each drive bearing 323. Each drive bearing 323 is provided with helical teeth 42. The support frame 2 is provided with tooth grooves 43 corresponding to the helical teeth 42. The helical teeth 42 of the drive bearings 323 at both ends of the mounting base 1 and the tooth grooves 43 of the support frame 2 are oriented in opposite directions.

[0025] This application also discloses a working method of an automatic wire storage device for a current transformer wire storage ring, including the following steps: S1, based on the number of copper wires to be wound, place a corresponding number of winding reels on the support frame; S2. Connect the starting end of the copper wire to one end of the winding reel and start the equipment to wind the wire; S3. Based on the position of the support rod, the clutch module of the axial drive unit controls the drive bearing on the corresponding side to move closer to the support rod and the drive bearing on the other side to move away from the support rod.

During the lateral movement of the support rod, the position of the support rod is detected. If the support rod reaches the end position on one side of its movement direction, it is determined that the current copper wire is wound to one end of the winding reel, and jumps to S5 to perform the reversal operation. Otherwise, the corresponding drive bearing continues to drive the support rod to move. S5, the clutch module of the axial drive unit adjusts the drive bearings, so that the drive bearings that were originally close to the support rod are moved away from the support rod, and the drive bearings that were far away from the support rod are moved closer to the support rod. During the adjustment process, each drive bearing is kept rotating at a constant speed, and then jumps back to S4 to cycle.

[0026] This application improves production efficiency by setting multiple wire storage structures 3 at different heights, thereby enabling the simultaneous winding of multiple sets of copper wires. Simultaneously, by providing axial drive components 4 on each wire storage structure 3, the clutch module 41 of the axial drive component 4 can automatically control the connection between the drive bearing 323 and the support rod 31. While the support rod 31 rotates circumferentially, lateral displacement during rotation is achieved through helical teeth 42 and tooth grooves 43. The direction of movement is adjusted by changing the drive bearing 323 that is connected to the support rod 31. During adjustment, each drive bearing 323 rotates at a uniform speed. This design ensures that the helical teeth 42 and the tooth grooves 43 fit together when the drive bearings 323 and the support rod 31 are engaged, preventing damage caused by collisions. Through the above structural design, the support rod 31 can achieve uniform reciprocating motion in the left and right directions while rotating, ensuring that the copper wire is wound evenly on the winding reel. It can also achieve automatic wire arrangement during the winding process, solving many inherent technical problems in traditional processes such as easy wear of copper wire, uneven wire winding, and easy tangling of multi-strand wires. It achieves a qualitative leap from simple "winding" to intelligent "wire arrangement", ensuring high quality and high reliability in the winding process.

[0027] Furthermore, the wire storage structure 3 of this application sets the copper wire winding range within the regular space formed by the support rod 31, the baffle block 33, and the drive bearing 323. The copper wire no longer rubs against the external rough baffle 321 or other components, fundamentally avoiding damage to the insulation layer and ensuring the electrical safety performance of the final current transformer. At the same time, the conversion of the winding direction is achieved by detecting the position of the winding reel, ensuring that the copper wire can be arranged neatly in layers, ensuring uniform tension during subsequent wire output, eliminating the problem of copper wire curling and wire output jamming caused by disordered accumulation, making the entire wire feeding and winding process exceptionally smooth, and improving the stability of the wound finished product in the production process.

[0028] Meanwhile, in order to simultaneously achieve the winding of multiple sets of copper wires, this application forms a three-dimensional, high-density winding structure by uniformly arranging several wire storage structures 3 along the height direction of the support frame 2.

[0029] Furthermore, the drive mechanism of this application transmits driving force through drive bearings 323 and achieves axial movement during rotation by setting helical teeth 42. The clutch module 41 controls the alternating engagement and disengagement of the drive bearings 323 at both ends with the support rod 31. Simultaneously, the direction of axial movement is changed by the helical teeth 42 arranged in opposite directions on the surfaces of the drive bearings 323 at both ends of the mounting base 1. Specifically, the drive bearings 323 rotate clockwise, but the left drive bearing 323 has left-handed helical teeth, and the right drive bearing 323 has right-handed helical teeth. When the left drive bearing 323 engages with the support rod 31 and the right drive bearing 323 disengages from the support rod 31, the left drive bearing... The drive bearing 323 drives the support rod 322 to rotate and move laterally in one direction. Conversely, when the left drive bearing 323 is disengaged from the support rod 31 and the right drive bearing 323 is engaged with the support rod 31, the right drive bearing 323 drives the support rod 322 to rotate and move laterally in another direction. As an optimization of the solution, the bottom of the support rod 31 can be provided with a freely rotating helical tooth 42, which can support and guide the support rod 31. The entire process only needs to control the clutch state switching to achieve automatic reversal, without the need for complex independent servo control of axial movement, which reduces system cost and failure rate, and shows higher reliability and maintenance convenience in industrial environments with long-term continuous operation.
