Enamelled wire bow structure

Abstract

This utility model discloses an enameled wire bow structure, which includes a bracket, a lifting drive device, a bow, bow plates, wire guide wheels, and a wheel frame. A wire guide groove is formed between two bow plates, and a wire guide passage is formed between two wire guide wheels. The enameled wire moves within the wire guide groove formed between the two bow plates. The wire guide groove provides axial constraint to the wire spool, and the wire guide passage between the two wire guide wheels smoothly guides the enameled wire into the wire guide groove, providing radial constraint to the wire spool. The enameled wire is confined within the three-dimensional channel formed by the combination of the wire guide groove and the wire guide passage, resulting in good guiding and limiting effects. This effectively prevents large swings or slippage of the enameled wire, ensuring the wire winding effect. Furthermore, the fiber optic sensor detects and, in conjunction with the lifting drive device, drives the wire bow to rise and fall in accordance with the height changes of the enameled wire winding layer on the spool, further improving the winding quality and ensuring product quality.

Description

Technical Field

[0001] This utility model relates to the field of wire winding mechanism technology, specifically to an enameled wire bow structure applied to a winding machine. Background Technology

[0002] The enameled wires processed in the enameled wire production line need to be wound onto a take-up reel for packaging and sale. Therefore, this process requires the enameled wires to be neatly and tightly arranged and wound on the take-up reel.

[0003] In the existing technology, the winding of enameled wire is mostly achieved by using a take-up bow installed on a take-up machine. The take-up bow is equipped with a guide wheel, which guides the enameled wire to be positioned and arranged on the drum of the take-up reel. However, the surface of the guide wheel is smooth, and the enameled wire is prone to slippage or skipping during guidance, making it difficult to achieve a tight arrangement of the enameled wire. Especially under high-speed winding conditions, it can easily lead to wire misalignment or overlapping defects, affecting the winding effect. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a structurally sound enameled wire bow structure with excellent wiring performance.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A wire bow structure includes a bracket, a lifting drive device, a wire bow, bow plates, wire guide wheels, and a wheel frame. The wire bow is movably mounted on the bracket via a linear slide rail assembly. The lifting drive device is mounted on the bracket and can drive the wire bow to move up and down relative to the bracket. Both ends of the wire bow are bent downward to form mounting ends. The two ends of the two bow plates are set on the corresponding mounting ends, and a wire guide groove is formed between the two bow plates. Two wire guide wheels are mounted on the wire bow via a wheel frame at positions above the wire guide groove, and a wire guide groove is formed between the two wire guide wheels.

[0007] As a preferred embodiment of this utility model, an optical fiber sensor is provided at the end of the mounting end. After one turn, the thickness of the wire layer on the reel increases, which just blocks the optical fiber sensor. The optical fiber sensor feeds back to the controller, and the controller controls the lifting drive device to work, thereby raising the height of the wire guide bow accordingly. This ensures that the wire guide groove can always rise and fall with the change in the height of the enameled wire winding layer on the reel drum, thus ensuring the wire laying effect.

[0008] In a preferred embodiment of this invention, the lifting drive device includes a motor, a ball screw, a ball nut, and a nut fixing block. One end of the nut fixing block is fixedly mounted on the back of the cable bow, and the other end is provided with a ball nut. The ball screw is screwed onto the ball nut. The motor is fixedly mounted on the bracket via a mounting base, and the drive shaft of the motor is connected to one end of the ball screw via a universal coupling. This design offers high lifting accuracy and good stability.

[0009] In a preferred embodiment of this invention, the wheel frame is U-shaped, with elongated holes on the straight sections on both sides. A shim is provided on the cable guide corresponding to the position of the straight hole, and a screw passes through the elongated hole and is mounted on the shim. The elongated holes allow the wheel frame, along with the cable guide rollers on it, to be adjusted vertically within a certain range.

[0010] As a preferred embodiment of this utility model, the outer circumferential surface of the cable guide wheel is provided with a wire groove, which provides more reliable vertical positioning, prevents the enameled wire from coming off the guide wheel, and improves the wire guiding effect.

[0011] In a preferred embodiment of this invention, a front stabilizing guide wheel is provided on the cable bow at a position above the two cable guide wheels. The enameled wire first passes through the front stabilizing guide wheel for initial guidance and stabilization, effectively reducing the excess sway and vibration of the enameled wire entering the cable laying area.

[0012] In a preferred embodiment of this invention, the outer peripheral edge of the front stabilizing guide wheel is provided with a flange. This effectively prevents the enameled wire from accidentally slipping off the front stabilizing guide wheel during the pre-stabilization process.

[0013] As a preferred embodiment of this utility model, a lead wire guide wheel is provided on the bracket at the position above the front stabilizing guide wheel, so that the enameled wire enters the front stabilizing guide wheel and the wire laying system in a more ideal expected direction.

[0014] As a preferred embodiment of this utility model, the outer circumferential surface of the lead guide wheel is provided with a wire groove to prevent the enameled wire from coming off the guide wheel and improve the wire conduction effect.

[0015] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonably designed. The enameled wire moves in the wire guide groove formed between the two bow plates. The wire guide groove provides axial constraint to the wire spool through the wire guide groove. The wire guide groove formed between the two wire guide wheels smoothly guides the enameled wire into the wire guide groove, providing radial constraint to the wire spool through the wire guide groove. The enameled wire is restricted to run in the three-dimensional channel formed by the cooperation of the wire guide groove and the wire guide groove. The guiding and limiting effect is good, which can effectively avoid large swings or slippage of the enameled wire, ensure the wire laying effect, effectively improve the winding quality, and guarantee the product quality.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] See Figures 1 to 3 The enameled wire bow structure provided in this embodiment includes a bracket 1, a lifting drive device 2, a bow 3, a bow plate 4, a bow guide wheel 5, a wheel frame 6, a front stabilizing guide wheel 7, and a lead wire guide wheel 8.

[0022] The bow cable 3 is movably mounted on the bracket 1 via a linear slide rail assembly. Specifically, the linear slide rail is fixedly mounted on both sides of the front of the bracket 1, and a slider adapted to it is movably mounted on the linear slide rail. The bow cable 3 is fixed to the slider by screws.

[0023] The lifting drive device 2 is mounted on the bracket 1 and can drive the bow cable 3 to move up and down relative to the bracket 1. Specifically, the lifting drive device 2 includes a motor 21, a ball screw 22, a ball nut 23, and a nut fixing block 24. A slot is provided on the bracket 1 for the nut fixing block 24 to move vertically. One end of the nut fixing block 24 passes through the slot and is fixed to the back of the bow cable 3 by screws. The other end of the nut fixing block 24 is provided with a ball nut 23, and the ball screw 22 is screwed onto the ball nut 23. The motor 21 is fixed to the back of the bracket 1 via a mounting base 25. The drive shaft of the motor 21 is connected to one end of the ball screw 22 via a universal coupling 26. The motor 21 drives the ball screw 22 to rotate via the universal coupling, and the ball nut 23 converts the rotational motion into linear motion, thereby driving the ball nut 23 and the nut fixing block 24 to move up and down, achieving high-precision linear lifting of the bow cable 3.

[0024] The two ends of the bow 3 are bent downward to form the mounting ends. The two ends of the two bow pieces 4 are set on the corresponding mounting ends, and the two bow pieces 4 form a bow guide groove 41. Specifically, the two bow pieces 4 are fixed on the mounting ends by passing screws through them. Preferably, a spring is sleeved on the screw at the position between the two bow pieces 4. The two bow pieces 4 are separated to form the bow guide groove 41 by the support of the spring.

[0025] Two cable guide rollers 5 are mounted on the cable bow 3 via a wheel frame 6, positioned above the cable guide groove 41. Specifically, the wheel frame 6 is U-shaped, with elongated holes on its straight sides. A shim is positioned on the cable bow 3 corresponding to the straight holes, and screws pass through the elongated holes and are mounted on the shims. The two cable guide rollers 5 are positioned at the bottom of the wheel frame 6. The elongated holes allow the wheel frame 6 and the cable guide rollers 5 to be adjusted vertically within a certain range to accommodate cable routing requirements of different diameter coils, improving the routing effect. A cable routing groove 51 is formed between the two cable guide rollers 5. Preferably, a wire groove is provided on the outer circumferential surface of the cable guide rollers 5 to provide more reliable vertical positioning, preventing the enameled wire from detaching from the guide rollers and ensuring good wire routing.

[0026] The front stabilizing guide wheel 7 is positioned above the two wire guide wheels 5 via an axle on the wire bow 3. Before entering the critical wire guide wheels 5 and wire guide groove 41 area, the enameled wire passes through the front stabilizing guide wheel 7 for initial guidance and stabilization, effectively reducing the residual sway and jitter of the enameled wire entering the wire laying area, and improving the subsequent wire laying accuracy and stability. Preferably, the outer peripheral edge of the front stabilizing guide wheel 7 is provided with a flange. The flange forms a physical barrier, effectively preventing the enameled wire from accidentally slipping out of the front stabilizing guide wheel 7 during the pre-stabilization process, ensuring the reliability of the pre-stabilized wire.

[0027] The lead wire guide wheel 8 is positioned above the front stabilizing guide wheel 7 according to the desired direction of the enameled wire entering the front stabilizing guide wheel 7 during production, so that the enameled wire enters the front stabilizing guide wheel 7 in a more ideal and expected direction. Preferably, a wire groove is provided on the outer circumferential surface of the lead wire guide wheel 8 to prevent the enameled wire from coming off the guide wheel and improve the wire guiding effect.

[0028] Preferably, fiber optic sensors 9 are provided at the ends of the two mounting ends of the cable bow 3, i.e., a fiber optic transmitting module with fiber optic sensor 9 is mounted on one mounting end, and a fiber optic receiving module with fiber optic sensor 9 is mounted on the other mounting end. After one turn, the increased thickness of the wire layer on the spool blocks the light emitted by the fiber optic transmitting module. The fiber optic receiving module, unable to receive light, sends feedback to the controller, which then controls the lifting drive device 2 to raise the height of the cable bow 3 accordingly. This ensures that the fiber optic receiving module can receive the light emitted by the fiber optic transmitting module, and that the cable guide groove 41, i.e., the cable laying point, always rises in accordance with the height change of the enameled wire winding layer on the spool, ensuring effective cable laying.

[0029] When working, see Figure 4 The present invention relates to a wire bow structure that is installed on the telescopic mechanism of a winding machine. Specifically, the bracket 1 is installed on the telescopic arm 10 of the telescopic mechanism. The telescopic arm 10 extends and retracts to allow the wire bow structure to reciprocate along the axial direction of the wire reel. The enameled wire 11 is drawn and wound around the lead guide wheel 8 and the front stabilizing guide wheel 7, and then passes through the wire guide groove 51 and the wire guide groove 41. During winding, the enameled wire 11 can move within the wire guide groove 41. The wire guide groove 41 provides axial constraint to the wire reel and radial constraint to the wire reel. This restricts the enameled wire to run within the three-dimensional channel formed by the wire guide groove 41 and the wire guide groove 51, resulting in good guiding and limiting effects. This effectively prevents the enameled wire from swinging or slipping significantly, thus improving the wire laying effect.
