Description

Technical Field

[0001] The present invention relates to the technical field of enameled wire winding, and more specifically, to a wire winding device for the production of micro enameled wire with high fatigue performance. Background Art

[0002] The micro enameled wire with high fatigue performance is a specially designed wire. Its main use is in electronic or electrical equipment that requires high strength and fatigue resistance. This enameled wire has high flexibility and operability, and can be easily bent, twisted or woven into the required shape. And through special treatment or material selection, this wire can maintain its electrical conductivity and structural integrity for a long time under repeated bending or vibration, which makes it particularly suitable for applications in environments that require repeated movement or vibration, such as micro motors, antennas or connectors in mobile devices, etc. Such enameled wires usually have a very small diameter, which is suitable for the miniaturization requirements of electronic devices while maintaining effective electrical conductivity. In addition, the outer layer of the enameled wire is coated with an insulating paint, which not only provides excellent electrical insulation performance, but also can prevent the influence of environmental factors such as oxidation and corrosion.

[0003] The production process of enameled wire mainly includes steps such as pretreatment, winding, drying, dipping in paint, drying, shaping, wire drawing, coating a protective layer, drying, winding, etc. However, the existing enameled wire winding equipment usually requires manual intervention to replace the winding drum, and wind the cut wire around the replaced winding drum. This not only increases the labor cost, but also has low winding operation efficiency. At the same time, there are certain safety hazards. Each time the winding drum is replaced, the yarn conveying device needs to be stopped, increasing the start-stop times of the yarn conveying device, which is not conducive to improving the winding efficiency.

Detailed implementation manners

[0029] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0030] Refer to the attached drawings of the specification Figures 1 to 6, A take-up device for producing micro enameled wires with high fatigue performance, comprising: at least two take-up rollers 1, a take-up roller drive assembly 101, a guiding wire-feeding mechanism 2, and a reciprocating mechanism 3. A sliding seat 301 is arranged on the reciprocating mechanism 3, and the sliding seat 301 reciprocates along a trajectory perpendicular to the enameled wire conveying direction. The enameled wire passes through the sliding seat 301 after being guided by the guiding wire-feeding mechanism 2 and is wound around the take-up roller 1; A clamping mechanism 4 and a wire-cutting mechanism 5 are arranged on the sliding seat 301. The clamping mechanism 4 is used to clamp or loosen the enameled wire, and the wire-cutting mechanism 5 is used to cut the enameled wire. A loading and unloading mechanism 6 is arranged on one side of the two take-up rollers 1; A telescopic assembly 7 is further arranged on the sliding seat 301. The telescopic assembly 7 is used to drive the clamping mechanism 4 to move along the enameled wire conveying direction. A wire clamping mechanism 8 is arranged on the take-up roller 1, and the wire clamping mechanism 8 includes a first wire clamping piece 801 and a second wire clamping piece 802; Before take-up, the clamping mechanism 4 clamps the initial end of the enameled wire, and the telescopic assembly 7 drives the initial end of the enameled wire to move into contact with the surface of the take-up roller 1. The reciprocating mechanism 3 drives the sliding seat 301 to drive the initial end of the enameled wire to move into the first wire clamping piece 801 for clamping, and then the clamping mechanism 4 is loosened, and the take-up operation is carried out by driving the take-up roller 1 to rotate; After take-up, the clamping mechanism 4 clamps the enameled wire. The reciprocating mechanism 3 drives the sliding seat 301 to drive the enameled wire to move into the second wire clamping piece 802 for clamping, and the enameled wire is cut by the wire-cutting mechanism 5, so that the part of the enameled wire staying on the clamping mechanism 4 forms a new initial end, and the part staying in the second wire clamping piece 802 forms the end of the wound enameled wire; The loading and unloading mechanism 6 is used to unload the take-up roller 1 after take-up is completed and reload a new take-up roller 1 to the take-up station; The reciprocating mechanism 3 is used to drive the sliding seat 301 to drive the enameled wire to move along, so that the enameled wire enters the second wire clamping piece 802.

[0031] It should be noted that, for the two winding rollers 1, one is in the winding state and the other is in the waiting-to-wind state. The axial direction of the reciprocating mechanism 3 is the same as that of the winding roller 1. The enameled wire guided and released by the guiding and unwinding mechanism 2 passes through the sliding seat 301 and is wound around the winding roller 1 through the sliding seat 301. The winding roller driving assembly 101 can be a motor, and the output end of the motor is connected to the winding roller 1. The winding roller 1 is driven to rotate by the motor for winding. The guiding and unwinding mechanism 2 can be an unwinding reel and multiple guiding wheels to unwind the enameled wire at a constant speed and guide it. The telescopic assembly 7 can be a cylinder. When the end of the enameled wire is pulled by the telescopic assembly 7 towards the winding roller 1, if the height of the end of the enameled wire is higher than the surface height of the waiting-to-wind winding roller 1, when the enameled wire is driven by the reciprocating mechanism 3 to move towards the clamping piece 801, since the height of the end of the enameled wire is higher than the surface height of the waiting-to-wind winding roller 1, it will cause the problem that the enameled wire cannot be clamped into the clamping piece 801. Therefore, it is necessary to keep the height of the end of the clamped enameled wire lower than the surface height of the waiting-to-wind winding roller 1.

[0032] It should also be noted that a guide shaft 8021 is fixedly arranged on the clamping piece 802, and the surface height of the guide shaft 8021 is aligned with the inlet end of the clamping piece 802. When it is necessary to fix the end of the enameled wire after winding, the end of the enameled wire can be driven by the reciprocating mechanism 3 to move towards the clamping piece 802, and the enameled wire is wound around the guide shaft 8021, so that the enameled wire can be directly clamped into the clamping piece 802 through the restriction of the guide shaft 8021, making it convenient to fix the end of the enameled wire after winding. And the clamping piece 802 is arranged at the edge of the winding roller 1 and will not hinder its winding. Both the clamping piece 801 and the clamping piece 802 are elastic metal pieces, similar to hairpins, and a plurality of clamping pieces 801 and 802 are arranged along the axial direction of the winding roller 1. The clamping piece 801 is arranged at the side position of the winding part of the winding roller 1, and the clamping piece 802 is arranged on the side baffle of the winding roller 1.

[0033] The implementation scenario is as follows: First, the wire guiding and paying-off mechanism 2 pays off the enameled wire. The winding roller driving assembly 101 drives the winding roller 1 to rotate for winding. During the winding process, the reciprocating mechanism 3 drives the sliding seat 301 to reciprocate, guiding the enameled wire so that the enameled wire can be closely arranged and wound on the winding roller 1. When the winding roller 1 in the winding state is about to finish winding, the reciprocating mechanism 3 drives the sliding seat 301 to drive the enameled wire to move towards the direction close to the second wire clamping piece 802, and the end of the enameled wire is fixed by being stuck in the guide shaft 8021 through the guide shaft 8021. Then, the clamping mechanism 4 can clamp and fix the enameled wire, and the wire cutting mechanism 5 cuts the enameled wire. Subsequently, the telescopic assembly 7 can drive the clamping mechanism 4 to move towards another winding roller 1 to be wound until it exceeds the winding roller 1 to be wound. As the reciprocating mechanism 3 drives the sliding seat 301 to reciprocate, the first wire clamping piece 801 arranged on the winding roller 1 to be wound clamps the enameled wire. Then, the clamping mechanism 4 releases the enameled wire, and the telescopic assembly 7 retracts and resets. As the winding roller 1 winds, the enameled wire is wound, and there is no need to stop the machine to replace the winding roller 1, realizing the non-stop winding of the enameled wire.

[0034] In the above technical solution, since the height of the end of the enameled wire needs to be lower than the surface height of the winding roller 1 to be wound, and when the end of the enameled wire is clamped by the clamping mechanism 4, it is necessary to ensure the stable clamping of the enameled wire, then the clamping end of the clamping mechanism 4 needs to wrap the enameled wire. Therefore, during the process of driving the clamping mechanism 4 to move towards another winding roller 1 to be wound by the telescopic assembly 7, there will be an interference problem between the clamping end of the clamping mechanism 4 and the winding roller 1 to be wound. For this reason, the present invention proposes a linear driving mechanism 9, which is used to increase the height of the enameled wire during the process of driving the end of the enameled wire to move towards another winding roller 1 to be wound, and reset the height of the enameled wire after the end of the enameled wire exceeds the winding roller 1 to be wound.

[0035] Specifically, referring to the attached drawings of the specification Figure 7 , a linear driving mechanism 9 is further arranged on the sliding seat 301. The linear driving mechanism 9 includes a fourth driving member 901. The fourth driving member 901 is installed on the sliding seat 301, and a bottom plate 902 is installed at the output end of the fourth driving member 901. The telescopic assembly 7 is installed on the bottom plate 902.

[0036] It should be noted that the fourth driving member 901 is a cylinder. The cylinder drives the bottom plate 902 to drive the telescopic assembly 7 to lift the height, so that the height of the end of the enameled wire can be lifted, and after the end of the enameled wire exceeds the winding roller 1 to be wound, the height of the enameled wire is reset, so that the enameled wire can contact the surface of the winding roller 1.

[0037] In the above technical solution, after the winding roller 1 in the winding state finishes winding, when winding another winding roller 1 in the to-be-wound state, since the guiding wire-feeding mechanism 2 is still feeding wire at a constant speed during the process of cutting the enameled wire, and at this time, the winding roller 1 that has finished winding and the winding roller 1 to be wound have not completed the switching yet, the enameled wire between the wire-feeding end of the guiding wire-feeding mechanism 2 and the clamping end of the clamping mechanism 4 is in a slack state. However, when the end of the enameled wire is clamped into the first wire clamping piece 801, if the enameled wire is in a slack state, it is difficult to clamp the enameled wire into the first wire clamping piece 801, and even if the enameled wire is clamped into the first wire clamping piece 801, during winding, if the enameled wire is in a slack state, it will also cause the wound enameled wire to be in a slack state, affecting normal winding. For this reason, the present invention proposes a wire tightening mechanism 10, which is used to ensure that the enameled wire between the sliding seat 301 and the clamping end of the clamping mechanism 4 is in a tensioned state when the end of the enameled wire is clamped into the first wire clamping piece 801 and when the enameled wire is wound.

[0038] Specifically, referring to the attached Figure 8 to the specification, a wire tightening mechanism 10 is further arranged in the sliding seat 301. The wire tightening mechanism 10 includes a through port 1001, and the through port 1001 is opened in the sliding seat 301. A wire guiding hole 3011 is opened on the sliding seat 301. The enameled wire passes through the sliding seat 301 through the wire guiding hole 3011, and the through port 1001 is communicated with the wire guiding hole 3011. A fifth driving member 1002 is installed on one side of the sliding seat 301. The output end of the fifth driving member 1002 extends into the through port 1001, and a bidirectional lead screw 1003 is installed. Two sliding plates 1004 are in threaded engagement with the bidirectional lead screw 1003. Roller wheels 1005 are arranged on both sliding plates 1004. The enameled wire is located between the two roller wheels 1005.

[0039] It should be noted that the fifth driving member 1002 is a motor. By driving the bidirectional lead screw 1003 to rotate through the motor, the two sliding plates 1004 are in threaded engagement with the bidirectional lead screw 1003, so that the two sliding plates 1004 drive the two roller wheels 1005 to move closer to each other, and the enameled wire is clamped between the two roller wheels 1005, so that before the enameled wire is cut, the enameled wire between the sliding seat 301 and the clamping mechanism 4 is ensured to be in a tensioned state by the extrusion of the two roller wheels 1005 on the enameled wire.

[0040] In the above technical solution, when the enameled wire is clamped into the first wire clamping piece 801 by the wire tightening mechanism 10, it is ensured that the enameled wire between the sliding seat 301 and the clamping end of the clamping mechanism 4 is in a tensioned state. And in order to ensure the tight winding of the enameled wire, during the winding process, it is also necessary to ensure that the enameled wire is in a tensioned state. However, during the switching process between the fully wound winding roller 1 and the winding roller 1 to be wound, since the guiding wire feeding mechanism 2 is always in a state of uniform wire feeding, the enameled wire between the wire outlet end of the guiding wire feeding mechanism 2 and the sliding seat 301 is not subject to any tension force and is in a slack state. In order to ensure the winding tension, the winding speed of the winding roller 1 needs to be increased. And at this time, the enameled wire between the sliding seat 301 and the winding roller 1 is in a tensioned state. But currently, there are two major problems in the processing of ultra-fine copper alloy wire materials. One is that it needs to go through multiple passes of deformation and annealing, which not only increases the cost, but also is prone to wire breakage during this process. The other is that the process is difficult to control, and improper annealing is likely to cause a decrease in performance. Therefore, currently, an on-line heating method is usually adopted to perform warm processing on pure copper wire with a deformation amount of more than 80%, so that the copper wire maintains a certain deformation stress and has good ductility. And at this time, the enameled wire between the sliding seat 301 and the winding roller 1 is in a tensioned state. Then when the winding speed of the winding roller 1 is increased, due to the influence of warm processing on the enameled wire, the ductility is enhanced. Increasing the winding speed of the winding roller 1 means that the tension force of the enameled wire between the sliding seat 301 and the winding roller 1 becomes larger, and then two phenomena will occur. One is that the clamping force of the first wire clamping piece 801 is large enough, so that the enameled wire between the sliding seat 301 and the first wire clamping piece 801 is stretched; the other is that the clamping force of the first wire clamping piece 801 is insufficient, so that the enameled wire clamped by the first wire clamping piece 801 slips off. However, both of the above two phenomena will affect the normal winding. For this reason, the present invention proposes a cooling mechanism 11, which is used to blow air to cool the enameled wire between the sliding seat 301 and the winding roller 1 in a wind cooling manner during winding, so as to solve the problem that the enameled wire is affected by warm processing, the ductility is enhanced, and when the winding speed of the winding roller 1 is increased, the tension force of the enameled wire between the sliding seat 301 and the winding roller 1 becomes larger, thus affecting the normal winding.

[0041] Specifically, referring to the attached drawings of the specification Figure 9 , the wire winding device further includes a cooling mechanism 11. The cooling mechanism 11 includes two fixed boxes 1101. Two piston plates 1102 are installed on one side of the sliding seat 301. The two piston plates 1102 are slidably and sealingly connected to the corresponding fixed boxes 1101. Air inlet holes and air outlet holes are provided on both of the two fixed boxes 1101, and one-way valves are provided in both the air inlet holes and the air outlet holes. The air outlet ends of the two air outlet holes are both communicated with a communicating pipe 1103. Two air outlet pipes 1104 are provided on the sliding seat 301. The two communicating pipes 1103 are communicated with the corresponding air outlet pipes 1104. A plurality of air outlet holes 1141 are provided on the air outlet pipes 1104, and the air outlet ends of the air outlet holes 1141 point to the enameled wire.

[0042] It should be noted that during the winding process of the winding roller 1, the reciprocating mechanism 3 drives the sliding seat 301 to reciprocate, so as to realize the close arrangement and winding of the enameled wire. At the same time, the two piston plates 1102 can be driven by the sliding seat 301 to reciprocate in the corresponding fixed box 1101. When the piston plate 1102 reciprocates in the fixed box 1101, air can be drawn into the fixed box 1101 through the one-way valve arranged in the air inlet hole, and through the reciprocating sliding of the piston plate 1102, the air drawn into the fixed box 1101 is sent into the air outlet pipe 1104 through the one-way valve in the air outlet hole and the connecting pipe 1103, and is blown to the enameled wire between the sliding seat 301 and the winding roller 1 through the air outlet holes 1141 opened on the air outlet pipe 1104, so as to realize the cooling of the enameled wire.

[0043] It should also be noted that in order to solve the problem that accelerating the winding speed of the winding roller 1 will cause the tension of the enameled wire between the sliding seat 301 and the winding roller 1 to increase, the distance between the sliding seat 301 and the winding roller 1 can also be shortened (for example, by setting the sliding seat 301 into two parts up and down, the upper part can move linearly along the axial direction of the winding roller 1 on the lower part, and the wire guiding hole 3011 is arranged on the upper part of the sliding seat 301, and a cylinder is used to push the upper part towards the winding roller 1, so as to achieve the effect of shortening the distance), so as to reduce the tension of the enameled wire between the sliding seat 301 and the winding roller 1 and solve the influence of accelerating the winding speed of the winding roller 1 on the increase of the enameled wire tension.

[0044] In the above technical solution, the air outlet pipes 1104 are arranged on both sides of the enameled wire between the sliding seat 301 and the winding roller 1 to blow air to cool the enameled wire. However, due to the shape setting of the winding roller 1, the heights of both ends of the winding roller 1 are higher than the surface height of the middle part of the winding roller 1. Therefore, the air outlet pipes 1104 will hinder the winding during the winding process. For this reason, the present invention proposes an adjusting mechanism 12, so that during the winding process, when the air outlet pipe 1104 contacts the end of the winding roller 1, the air outlet pipe 1104 can swing to avoid the air outlet pipe 1104 affecting the normal winding.

[0045] Specifically, referring to the attached drawings of the specification Figure 10 , an adjusting mechanism 12 is further arranged on the sliding seat 301. The adjusting mechanism 12 includes a groove 1201 opened on the sliding seat 301. Two hinge plates 1202 are hinged in the groove 1201, and a fixed block 1203 is fixedly arranged in the groove 1201. Elastic members II 1204 are arranged between the two hinge plates 1202 and the fixed block 1203.

[0046] It should be noted that the elastic member II 1204 is a spring. During the process of the sliding seat 301 driving the air outlet pipe 1104 to move, when the air outlet pipe 1104 contacts the end of the winding roller 1, the end of the winding roller 1 can squeeze the air outlet pipe 1104, causing the hinge plate 1202 to swing and stretch the spring, so as to solve the problem that the air outlet pipe 1104 hinders normal winding.

[0047] It should also be noted that a plurality of air outlet holes 1141 are arranged along the axial direction of the air outlet pipe 1104, so that when the hinge plate 1202 drives the air outlet pipe 1104 to swing, the enameled wire can still be blown to cool down.

[0048] Further, referring to the attached drawings of the specification Figure 2 The reciprocating mechanism 3 further includes a base 302. A driving member I 303 is installed on the base 302. The output end of the driving member I 303 is installed with a reciprocating lead screw 304. The sliding seat 301 is in threaded fit connection with the reciprocating lead screw 304.
