Description

Technical Field

[0001] This invention relates to the field of motor coil winding machine technology, and more particularly to a wire feeding mechanism for a horizontal winding machine. Background Technology

[0002] Horizontal winding machines are widely used in motor coil manufacturing, and their winding quality directly affects the electrical performance and mechanical reliability of the motor. During the motor coil winding process, the consistency of the diameter of the internal copper core and the integrity of the external insulating varnish of the enameled wire, as the conductive material, are crucial. If the enameled wire is subjected to uneven or excessive tension during winding, the copper core can easily be stretched and thinned, and the outer varnish layer can wear down or even peel off, thereby reducing the conductivity, withstand voltage rating, and service life of the motor coil.

[0003] Currently, the wire feeding mechanism of traditional horizontal winding machines mostly uses simple guide wheels, tensioners, or mechanical tensioning devices. These mechanisms provide relatively crude tension control of the enameled wire during the motor coil winding process, making dynamic adjustment and real-time compensation difficult. The tension fluctuation problem is particularly prominent under the following three typical operating conditions: 1. During the transverse winding of the enameled wire, due to the sudden change in inertia in the reversing areas at both ends of the winding post, the enameled wire is subjected to an impact tension at the moment of start-stop, resulting in a sudden increase in tension;

[0004] Second, when multiple layers are wound, the transition area between layers is prone to forming a "step" structure. When the enameled wire crosses the step, the frictional resistance increases sharply, changing from planar friction to climbing friction, resulting in excessive local tension.

[0005] Third, enameled wires of different diameters and materials are sensitive to tension to varying degrees. Traditional mechanisms lack the ability to adapt and adjust to different wire diameters, which can easily lead to excessive stretching of thin wires or insufficient tension of thick wires, resulting in loose wiring.

[0006] To address the impact of tension fluctuations during the winding process of enameled wire, this invention provides a wire feeding mechanism for a horizontal winding machine. Summary of the Invention

[0007] To address the aforementioned problems, the present invention provides a wire feeding mechanism for a horizontal winding machine, which solves the problems mentioned in the background art.

[0008] To achieve the above objectives, the embodiments of this application provide the following technical solution: The present invention provides a wire feeding mechanism for a horizontal winding machine, including a sliding table, a support frame, a reversing buffer unit, two sets of wire laying units, and a fine-tuning unit. The sliding table is guided and installed on the winding spindle of the winding machine. The support frame is movably disposed on the upper end face of the sliding table. A motor and a reducer are connected to the side wall of the support frame. The motor drives the reducer, which has three independently controllable first output shafts, a second output shaft, and a third output shaft. The reversing buffer unit is connected to the first output shaft. One set of wire laying units is connected to the second output shaft, and the other set of wire laying units is adjustablely disposed on the side wall of the support frame via a connecting seat. The two sets of wire laying units are used together to tension and guide the enameled wire. The fine-tuning unit is disposed on the side wall of the support frame and connected to the third output shaft, and the fine-tuning unit is located between the wire laying units and the reversing buffer unit.

[0009] The upper end of the sliding table is provided with symmetrical strip grooves, the lower end of the support frame is provided with lugs that slide with the strip grooves, a limit post is provided in the strip grooves, the lugs are slidably sleeved on the limit post, and a spring is sleeved on the limit post.

[0010] During the specific wiring process, the reversing buffer unit, wiring unit and fine-tuning unit work together to dynamically adjust the wiring path. When reversing, the reversing buffer unit slowly increases the wire supply length and reduces the winding turn density. Combined with the buffer movement of the support frame, it absorbs excess tension.

[0011] According to an advantageous embodiment, the reversing buffer unit includes a guide sleeve, on which a support arm connected to the first output shaft is provided. Two limiting rods are symmetrically arranged inside the guide sleeve. Two side plates are slidably arranged between the two limiting rods. A wire sleeve is rotatably arranged between the two side plates. A pressure spring acting on the side plates is sleeved on each of the two limiting rods. A U-shaped sleeve is engaged at the lower end of the two side plates. An electric push rod is connected to the lower end of the U-shaped sleeve and disposed on the inner wall of the guide sleeve. The control end of the electric push rod is electrically connected to the PLC main control system of the winding machine.

[0012] According to an advantageous embodiment, the wiring unit includes a shaft member consisting of a movable shaft and a fixed shaft rotatably connected. The outer wall of the shaft member is uniformly provided with limiting circular plates, and a lead wire guide sleeve is movably sleeved on the outer wall of the shaft member between two adjacent limiting circular plates. In the wiring unit connected to the second output shaft, the lead wire guide sleeve adjacent to the support frame is made of flexible material. An elliptical wheel is provided on the outer wall of the shaft at the connection position between the movable shaft and the fixed shaft, and the inner wall of the flexible material lead wire guide sleeve is interference-fitted with the elliptical wheel.

[0013] According to an advantageous embodiment, the side wall of the support frame is provided with a vertical guide groove, and bolt holes are evenly arranged on both sides of the vertical guide groove along its length direction. The connecting seat is disposed in the vertical guide groove and fixed to the bolt holes by bolts.

[0014] According to an advantageous embodiment, the fine-tuning unit includes two guide rollers rotatably disposed on the side wall of the support frame and arranged vertically and staggeredly. A limiting plate is connected between the shaft ends of the two guide rollers. A cam column is rotatably disposed on the outer wall of the limiting plate and located between the two guide rollers. The cam column is connected to a third output shaft.

[0015] According to an advantageous embodiment, it also includes a lead spool connected to the end of the winding post by a positioning bolt, the lead spool changing the end of the winding post into a gradually rounded chamfered shape.

[0016] According to an advantageous embodiment, one end of the guide sleeve is threadedly connected to a threaded plug, and a limiting plate is rotatably provided inside the threaded plug. The limiting plate has two limiting holes, and one end of each of the two limiting rods is inserted into the corresponding limiting hole.

[0017] According to an advantageous embodiment, the device further includes tension sensors, which are respectively disposed on the lead sleeve of the reversing buffer unit, the lead guide sleeve of the winding unit, and the lead roller and cam column of the fine-tuning unit. The tension sensors are connected to the PLC main control system of the winding machine via signal connection.

[0018] Compared with the prior art, the wire feeding mechanism of the horizontal winding machine provided by the present invention has the following beneficial effects: 1. The present invention, through the inertial buffer design of the support frame and damping spring, and the PLC pre-controlled reversing buffer unit (electric push rod drives the wire sleeve to move slowly), actively increases the wire supply length and forms a micro-gradient before reversing, effectively suppressing the sudden increase of impact tension during reversing start and stop, significantly reducing the tension peak during the reversing stage, thereby avoiding the copper core from being stretched and thinned and the enamel layer from peeling off, protecting the structure and performance of the enameled wire.

[0019] 2. This invention uses the cam column of the fine-tuning unit to operate synchronously with the commutation cycle. When an increase in tension is detected, it actively intervenes and instantly changes the path length of the enameled wire to absorb excess tension. At the same time, the gradual rounded chamfer design of the lead coil reduces the rigid friction of the interlayer climbing from a structural perspective. Through the synergy of the above two, it actively compensates for the sudden change in frictional resistance when crossing between layers, realizes the smoothness of the interlayer transition, and stabilizes the wire laying process.

[0020] 3. The present invention, through the design of a vertically adjustable connecting seat, can precisely adjust the spacing between the two sets of wiring units according to the copper core diameter, ensuring that the tension force matches the wire's tolerance; at the same time, the cooperation between the elliptical wheel and the flexible lead wire sleeve in the wiring unit can automatically fine-tune the path length for compensation under small-range tension fluctuations, realizing adaptive optimization wiring for enameled wires of different specifications, thereby ensuring the winding quality of the motor coil.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will now be described in further detail.

[0029] Please refer to the following: Figure 1 and Figure 2A wire feeding mechanism for a horizontal winding machine includes a sliding table 1, a support frame 2, a reversing buffer unit 3, two sets of wire laying units 4, and a fine-tuning unit 5. The sliding table 1 is guided and mounted on the winding spindle of the winding machine. The support frame 2 is movably disposed on the upper end face of the sliding table 1. A motor 21 and a reducer 22 are connected to the side wall of the support frame 2. The motor 21 drives the input shaft of the reducer 22 via a belt. The reducer 22 has a multi-stage gear set that distributes power to its three independently controllable output shafts (hereinafter referred to as the first output shaft, the second output shaft, and the third output shaft). (Shaft differentiation); the reversing buffer unit 3 is connected to the first output shaft of the reducer 22 via a coupling, and the reversing buffer unit 3 and the motor 21 are located on the same side; one set of cable laying units 4 is connected to the second output shaft of the reducer 22, and another set of cable laying units 4 is adjustablely mounted on the side wall of the support frame 2 via a connecting seat 6; the two sets of cable laying units 4 work together to guide the tension of the enameled wire; the fine-tuning unit 5 is mounted on the side wall of the support frame 2, and is connected to the third output shaft of the reducer 22, and the fine-tuning unit 5 is located between the cable laying unit 4 and the reversing buffer unit 3.

[0030] When using the above-mentioned wire feeding mechanism to wind enameled wire, firstly, adjust the installation position of the connecting seat 6 on the side wall of the support frame 2 according to the diameter of the copper core of the enameled wire, thereby adjusting the spacing between the two sets of wire feeding units 4. Specifically, the spacing should be appropriately increased as the diameter of the copper core of the enameled wire increases. Then, fix the enameled wire coil to the unwinding shaft of the horizontal winding machine and connect the winding post to the winding shaft of the horizontal winding machine. Subsequently, the wire end of the enameled wire coil is tensioned and guided by the two sets of wire feeding units 4 and then passes through the fine-tuning unit 5 and the reversing buffer unit 3 in sequence. Finally, fix the wire end to the winding post, and complete the work of distributing and arranging the enameled wire coil on the outer wall of the winding post through the horizontal winding machine.

[0031] It should be noted that during the lateral movement of the enameled wire, the tension on the wire changes. The two sets of wire-laying units 4 work together to balance the tension changes during this lateral movement. However, during the reversal of the lateral movement, the height difference between the wire layers causes a sudden change in mechanical resistance between the wires. At this point, a step is instantly formed at the starting position of the wire layer. When winding, the wire needs to cross this step, and the frictional resistance changes abruptly from planar friction to climbing friction. This sudden increase in resistance causes a sudden rise in the tension on the enameled wire. At this time, the fine-tuning unit 5... By compensating for the length of the tension zone of the enameled wire, the tension on the enameled wire is reduced in one step, which helps to reduce the problem of the diameter reduction caused by the enameled wire being stretched beyond its limit. At the same time, when the enameled wire changes direction from one end of the winding post to the other during the winding process, the starting and stopping inertia of the enameled wire winding will change the direction of the force on the enameled wire, causing instantaneous tension fluctuations in the enameled wire. At this time, the reversing buffer unit 3 acts in the opposite direction on the periphery of the enameled wire, changing the winding density of the enameled wire wound on the outer wall of the winding post during the reversing process, so that the interlayer transition forms a smooth process, thereby stabilizing the stress state of the enameled wire.

[0032] See Figure 1 and Figure 2 The upper end of the sliding table 1 is provided with symmetrical strip grooves 11, and the lower end of the support frame 2 is provided with two lugs 23, and the two lugs 23 are respectively located in the corresponding strip grooves 11. The fit gap between the strip groove 11 and the lugs 23 is ≤0.05mm to avoid the support frame 2 from shaking due to excessive gap, which would affect the wiring accuracy. A limit post is provided in the strip groove 11, and the lugs 23 are slidably sleeved on the outer wall of the limit post. Springs are sleeved on the outer walls of the limit posts on both sides of the lugs 23. The springs are damping springs to avoid resonance of the support frame 2 when changing direction.

[0033] During the reversing phase of the infeed mechanism, the tension of the enameled wire being pulled will fluctuate due to inertia during the start-stop reversing movement of the sliding table 1. By setting the support frame 2 and the sliding table 1 to a movable state, the inertial force of the support frame 2 can be effectively reduced through the buffering effect of the limit column and the spring, thereby reducing the tension fluctuation amplitude of the enameled wire during the reversing process.

[0034] See Figure 2 and Figure 4 The reversing buffer unit 3 includes a guide sleeve 31, on which a support arm 32 is provided. The support arm 32 is connected to the first output shaft on the reducer 22. A limit groove 33 is formed on the outer wall of the guide sleeve 31. Two limit rods 34 are symmetrically inserted inside the guide sleeve 31. Two side plates 35 are slidably arranged between the two limit rods 34. A wire sleeve 36 is rotatably arranged between the two side plates 35. A pressure spring 37 is sleeved on the outer side of the two limit rods 34 on the side of the two side plates 35 away from the wire sleeve 36. The pressure springs 37 on both sides cause the reversing buffer unit to... The wire sleeve 36 is located in the middle of the limiting rod 34. The lower ends of the two side plates 35 are jointly engaged with a U-shaped sleeve 38. The lower end of the U-shaped sleeve 38 is connected to an electric push rod 39, which is connected to the inner wall of the guide sleeve 31. The control end of the electric push rod 39 is electrically connected to the PLC main control system of the winding machine. One end of the guide sleeve 31 is threaded with a threaded plug 310. The threaded plug 310 has a limiting disk 311 inside, which has two limiting holes. One end of each of the two limiting rods 34 is inserted into the corresponding limiting hole.

[0035] The first output shaft directly drives the support arm 32 of the reversing buffer unit 3 through the coupling, adjusting the angle of the wire sleeve 36 pulling the enameled wire. When the enameled wire is about to be reversed from one end of the winding column to the other end, the PLC main control system of the winding machine issues a pre-command based on the encoder signal of the winding spindle before the sliding table 1 reverses, controlling the extension speed and stroke of the electric push rod 39. When the sliding table 1 stops in advance, and the wire sleeve 36 continues to move slowly under the drive of the electric push rod 39, the actual wire supply length of the enameled wire on the winding column increases slightly, which increases the winding turn spacing in the reversing starting area, thereby forming a gentle slope for interlayer transition on a microscopic level. This makes the stress state of the enameled wire more stable during the reversing stage, reducing the problem of the copper core being stretched thinner and the enamel layer peeling off after the tension exceeds the limit due to the inertial force during the reversing start and stop stage of the enameled wire winding process.

[0036] See Figure 5 As shown, the wiring unit 4 includes a shaft member, which consists of a movable shaft 41 and a fixed shaft 42, and the movable shaft 41 and the fixed shaft 42 are rotatably connected. Limiting circular plates 43 are evenly arranged on the outer wall of the shaft member, and a lead wire guide sleeve 44 is movably sleeved on the outer wall of the shaft member between two adjacent limiting circular plates 43. The lead wire guide sleeve 44 and the shaft member are movably set, allowing them to produce slight circumferential sliding when the friction is too large, which plays an overload protection role and avoids excessive local tension of the enameled wire.

[0037] The lead wire guide sleeve 44 on the cable unit 4 connected to the second output shaft of the reducer 22 is made of flexible material at the position adjacent to the support frame 2. The outer wall of the movable shaft 41 at the connection position between the movable shaft 41 and the fixed shaft 42 is provided with an elliptical wheel 45. The flexible lead wire guide sleeve 44 is made of high elastic silicone. The outer wall is clearance-fitted with the limiting circular plate 43, and the inner wall is interference-fitted with the elliptical wheel 45.

[0038] After the enameled wire is tensioned by the adjacent upper and lower lead guide sleeves 44, the shape of the enameled wire can be corrected, keeping the enameled wire smooth and straight, and ensuring the stability of the tension during the subsequent winding process. During the correction of the enameled wire, the movable lead guide sleeves 44 can automatically move relative to each other when the frictional resistance between the enameled wire and the lead guide sleeves 44 is too large, thereby reducing the resistance and improving the problem that the enameled wire in the area with excessive resistance during the winding process is stretched due to excessive tension, causing the copper core of the enameled wire to become thinner.

[0039] During the transition of the enameled wire from the wiring unit 4 to the fine-tuning unit 5, if the tension fluctuates during the wiring process, the movable shaft 41 connected to the second output shaft of the reducer 22 will be passively rotated under the torque caused by the tension change, thereby driving the elliptical wheel 45 to rotate. During the rotation of the elliptical wheel 45, the flexible lead wire sleeve 44 will be rotated simultaneously. The rotation of the elliptical wheel 45 forces the flexible lead wire sleeve 44 and the enameled wire to change periodically in terms of their wrap angle and tangent height on their surfaces, thereby achieving fine-tuning of the path length during the wiring process of the enameled wire and compensating for tension fluctuations. An increase of 10° in the wrap angle corresponds to an increase of 0.5mm in the path length.

[0040] See Figure 2 The support frame 2 has a vertical guide groove 24 on its side wall. Bolt holes are evenly arranged on both sides of the vertical guide groove 24 along its length. The connecting seat 6 is set in the vertical guide groove 24 and fixed to the bolt holes by bolts.

[0041] During the wiring process, because the enameled wires with different copper core thicknesses have different tensile strengths, the copper cores with larger diameters have greater tensile strength than those with smaller diameters. Therefore, the connecting seat 6 is detachable and the spacing between the two sets of wiring units 4 can be adjusted to ensure that the enameled wires with different copper core thicknesses will not deform after being tensioned and guided by the upper and lower adjacent lead sleeves 44.

[0042] See Figure 3 and Figure 6 The fine-tuning unit 5 includes two guide rollers 51 rotatably mounted on the side wall of the support frame 2. The two guide rollers 51 are staggered vertically, with the diameter of the upper guide roller 51 being larger than that of the lower guide roller 51. A limiting plate 52 is connected between the shaft ends of the two guide rollers 51. A cam column 53 is rotatably mounted on the outer wall of the limiting plate 52 between the two guide rollers 51. The cam column 53 is connected to the third output shaft in the reducer 22. It should be noted that the contour curve of the cam column 53 is specially designed, and its rotation cycle is synchronized with the reversing cycle of the sliding table 1. When the enameled wire experiences increased tension due to reversing inertia, the specific contour of the cam column 53 pushes the path of the enameled wire between the upper and lower guide rollers 51 to shift, which is equivalent to instantaneously reducing the length of the tensioning path, thereby absorbing excess tension and playing a dynamic buffering role.

[0043] The horizontal winding machine's wire feeding mechanism also includes a lead wire reel 7, which is connected to the end of the winding post by positioning bolts. The lead wire reel 7 changes the two ends of the winding post from a straight shape to a gradually rounded chamfered shape, with the radius of the chamfer being 1 / 5 of the winding post's diameter. During the stacking of enameled wire, rigid friction between the enameled wire and the winding post's edge can be avoided, reducing the resistance of interlayer climbing and improving the tension fluctuations experienced by the enameled wire during the stacking process.

[0044] It should be noted that the coordinated operation of this wire feeding mechanism relies on the PLC main control system of the winding machine. During the wire laying process, the tension sensor installed near the tension detection point provides real-time feedback signals. The tension sensor is respectively set on the lead sleeve 36, the lead guide sleeve 44, and the lead roller 51. The accuracy of the tension sensor is ≤0.1N. Combined with the position signal of the winding spindle encoder, the real-time tension state of the enameled wire is comprehensively judged. Based on this tension state, the speed of the motor 21, the speed of the three independent output shafts, the stroke of the electric push rod 39, and the phase of the adjusting cam column 53 are dynamically adjusted to achieve closed-loop tension control with multi-unit linkage. When the tension fluctuation is ≤0.5N, it is compensated by the wire laying unit 4, and when it is >0.5N, the fine-tuning unit 5 intervenes.

[0045] When using the above-mentioned wire feeding mechanism: S1, Installation and adjustment: Fix the sliding table 1 on the winding spindle of the winding machine, and ensure that the limit post and spring in the strip groove 11 are installed in place; at the same time, slide the support frame 2 onto the sliding table 1 through the lug 23; then adjust the position of the connecting seat 6 in the vertical guide groove 24 according to the diameter of the enameled wire copper core to set the spacing between the two sets of wire laying units 4.

[0046] S2. Wiring preparation: First, fix the enameled wire coil on the unwinding shaft of the winding machine. Then, install the winding post on the winding shaft and install the lead reel 7 on the end of the winding post with positioning bolts. Next, pass the enameled wire end through the lead guide sleeve 44 of the two sets of wire laying units 4, the two lead rollers 51 of the fine adjustment unit 5, and the lead sleeve 36 of the reversing buffer unit 3 in sequence. Finally, fix the wire end on the winding post.

[0047] S3. Winding start and linkage control: Start the winding machine, and the PLC main control system controls the actions of each unit in real time based on the encoder position signal and the feedback from the tension sensor.

[0048] During regular wiring, the two sets of wiring units 4 work together to tension and guide the enameled wire, and the lead sleeve 44 rotates adaptively to reduce local friction.

[0049] When the tension fluctuation is ≤0.5N, the wire laying unit 4 compensates by fine-tuning the enameled wire path length through the rotation of the elliptical wheel 45; when the fluctuation is >0.5N, the cam column 53 of the fine-tuning unit 5 rotates to change the enameled wire path between the guide rollers 51 to buffer the sudden tension change.

[0050] During the reversing phase, the PLC controls the electric push rod 39 to move at a preset speed and stroke, causing the wire sleeve 36 to move slowly, increasing the wire supply length, forming a gentle slope transition, and stabilizing the force on the enameled wire.

[0051] S4. Reversing buffer and dynamic adjustment: When the sliding table 1 reverses direction, the support frame 2 buffers inertia through the limit column and spring to reduce tension fluctuations. At the same time, the reversing buffer unit 3 reduces sudden changes in wire density and protects the enameled wire from stretching and enamel damage through the angle adjustment and slowing action of the wire sleeve 36.

[0052] S5. Completion and shutdown: After the winding is completed, stop the motor 21, cut the enameled wire and remove the winding post. At the same time, check the wear of each unit and clean or replace vulnerable parts such as the lead wire sleeve 44 if necessary.
