Description

Technical Field

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

[0002] High fatigue performance fine enameled wire is a specially designed wire, mainly used in electronic or electrical equipment that requires high strength and fatigue resistance. This enameled wire has high flexibility and workability, and can be easily bent, twisted or braided into the desired shape. After special treatment or material selection, this wire can maintain its conductive properties and structural integrity for a long time under repeated bending or vibration, which makes it particularly suitable for applications that require repeated movement or vibration environments, such as micromotors, antennas or connectors in mobile devices, etc. This type of enameled wire usually has a very small diameter, which is suitable for the miniaturization needs of electronic equipment while maintaining effective conductive properties. In addition, the outer layer of the enameled wire is coated with a layer of insulating varnish, which not only provides excellent electrical insulation performance, but also prevents the influence of environmental factors such as oxidation and corrosion.

[0003] The production process of enameled wire mainly includes pre-treatment, wrapping, drying, varnish dipping, drying, shaping, drawing, applying a protective layer, drying, and winding. However, the existing enameled wire winding equipment usually requires manual intervention to replace the reel and wind the cut wire onto the replaced reel. This not only increases labor costs, but also has low winding efficiency. At the same time, there are certain safety hazards. The yarn conveying device needs to be shut down each time the reel is replaced, which increases the number of starts and stops of the yarn conveying device, which is not conducive to improving the winding efficiency.

[0035] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Refer to the instruction manual Figures 1 to 6 A wire take-up device for producing fine enameled wire with high fatigue resistance comprises: at least two take-up rollers 1, a take-up roller drive assembly 101, a guide pay-off mechanism 2, and a reciprocating mechanism 3. The reciprocating mechanism 3 is provided with a slide 301, which reciprocates along a path perpendicular to the enameled wire conveying direction. The enameled wire is guided by the guide pay-off mechanism 2, passes through the slide 301, and is wound around the take-up roller 1.

[0037] The slide 301 is provided with a clamping mechanism 4 and a wire cutting mechanism 5. 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 provided on one side of the two winding rollers 1.

[0038] The slide 301 is also provided with a telescopic assembly 7, which is used to drive the clamping mechanism 4 to move along the conveying direction of the enameled wire. The winding roller 1 is provided with a wire clamping mechanism 8, which includes a wire clamping piece 1 801 and a wire clamping piece 2 802;

[0039] Before winding, 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 to contact the surface of the winding roller 1. The reciprocating mechanism 3 drives the slide 301 to move the initial end of the enameled wire to the wire clamping piece 801 for clamping. Then the clamping mechanism 4 is released, and the winding roller 1 is driven to rotate to perform the winding operation.

[0040] After winding, the clamping mechanism 4 clamps the enameled wire, and the reciprocating mechanism 3 drives the slide 301 to move the enameled wire to the second clamping piece 802 for clamping, and the wire cutting mechanism 5 cuts the enameled wire, so that the part of the enameled wire remaining on the clamping mechanism 4 forms a new starting end, and the part remaining in the second clamping piece 802 forms the ending end of the wound enameled wire;

[0041] The loading and unloading mechanism 6 is used to unload the winding roller 1 that has been wound and reload the new winding roller 1 to the winding station;

[0042] The reciprocating mechanism 3 is used to drive the slide 301 to drive the enameled wire to move, so that the enameled wire enters the second wire clamping piece 802.

[0043] It should be noted that, of the two winding rollers 1, one is in the winding state and the other is in the waiting state, the axial direction of the reciprocating mechanism 3 is the same as the axial direction of the winding roller 1, and the enameled wire guided by the guide wire-releasing mechanism 2 passes through the slide 301 and is wound on the winding roller 1 through the slide 301, the winding roller drive assembly 101 can be a motor, the output end of the motor is connected to the winding roller 1, and the winding roller 1 is driven by the motor to rotate for winding, and the guide wire-releasing mechanism 2 can be a wire-releasing reel and a plurality of guide wheels, which can pay out the enameled wire at a uniform speed and The guide, telescopic component 7 can be a cylinder. When the end of the enameled wire is pulled toward the winding roller 1 by the telescopic component 7, if the height of the end of the enameled wire is higher than the surface height of the winding roller 1 to be wound, when the enameled wire is driven to move toward the wire clamping piece 801 by the reciprocating mechanism 3, since the height of the end of the enameled wire is higher than the surface height of the winding roller 1 to be wound, it will cause the enameled wire to be unable to be stuck in the wire clamping piece 801. Therefore, it is necessary to keep the height of the clamped enameled wire end lower than the surface height of the winding roller 1 to be wound.

[0044] It should also be noted that a guide shaft 8021 is fixedly provided on the wire clamping piece 2 802, and the surface height of the guide shaft 8021 is aligned with the wire inlet end of the wire clamping piece 2 802, so that when the end of the enameled wire needs to be fixed, the end of the enameled wire can be driven to move toward the direction of the wire clamping piece 2 802 by the reciprocating mechanism 3, and the enameled wire is wound on the guide shaft 8021, so that the enameled wire can be directly inserted into the wire clamping piece 2 802 through the restriction of the guide shaft 8021, so that it can be wound After completion, it is convenient to fix the end of the enameled wire, and the wire clamping piece 2 802 is set on the edge of the winding roller 1, which will not hinder its winding. The wire clamping piece 1 801 and the wire clamping piece 2 802 are both elastic metal sheets, similar to hairpins, and the wire clamping piece 1 801 and the wire clamping piece 2 802 are distributed along the axial direction of the winding roller 1. The wire clamping piece 1 801 is set on the side position of the winding part of the winding roller 1, and the wire clamping piece 2 802 is set on the side baffle of the winding roller 1.

[0045] The specific implementation scenario is as follows: first, the guiding pay-off mechanism 2 pays off the enameled wire, and the winding roller 1 is driven to rotate and rewind by the winding roller drive assembly 101. During the winding process, the reciprocating mechanism 3 drives the slide 301 to reciprocate to guide the enameled wire so that the enameled wire can be tightly arranged and rewinded on the winding roller 1. When the winding roller 1 in the winding state is about to complete the winding, the reciprocating mechanism 3 drives the slide 301 to drive the enameled wire to move in the direction close to the wire clamping piece 2 802, and the end of the enameled wire is clamped in the guide shaft 8021 through the guide shaft 8021. The enameled wire can be fixed, and then the clamping mechanism 4 can be used to clamp and fix the enameled wire, and the wire cutting mechanism 5 can be used to cut the enameled wire. Subsequently, the clamping mechanism 4 can be driven by the telescopic component 7 to move toward the other winding roller 1 to be wound, until it exceeds the winding roller 1 to be wound, and the reciprocating mechanism 3 drives the slide 301 to move back and forth, so that the wire clamping piece 801 set on the winding roller 1 to be wound clamps the enameled wire, and then the clamping mechanism 4 releases the enameled wire, and the telescopic component 7 retracts and resets. As the winding roller 1 is wound, the enameled wire is wound, and there is no need to stop the machine to replace the winding roller 1, thereby realizing non-stop winding of the enameled wire.

[0046] In the above technical solution, since the height of the end portion of the enameled wire needs to be lower than the surface height of the winding roller 1 to be wound, and when the end portion of the enameled wire is clamped by the clamping mechanism 4, it is necessary to ensure stable clamping of the enameled wire, the clamping end of the clamping mechanism 4 is required to wrap the enameled wire, so that in the process of driving the clamping mechanism 4 to move to another winding roller 1 to be wound by the telescopic component 7, interference will be caused 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 drive mechanism 9, which is used to increase the height of the enameled wire in the process of driving the end portion of the enameled wire to move to another winding roller 1 to be wound, and reset the height of the enameled wire after the end portion of the enameled wire exceeds the winding roller 1 to be wound.

[0047] For details, please refer to the attached manual. Figure 7 A linear drive mechanism 9 is also provided on the slide 301. The linear drive mechanism 9 includes a fourth drive member 901. The fourth drive member 901 is installed on the slide 301. The output end of the fourth drive member 901 is installed with a base plate 902, and the telescopic component 7 is installed on the base plate 902.

[0048] It should be noted that the driving component 901 is a cylinder, which drives the base plate 902 to lift the telescopic component 7 so that it can lift the end of the enameled wire. 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.

[0049] In the above technical solution, after the winding roller 1 in the winding state has completed winding, when the other winding roller 1 in the waiting state is wound, since the guide pay-off mechanism 2 is still paying out the wire at a uniform speed during the process of cutting the enameled wire, and the winding roller 1 that has completed winding and the winding roller 1 to be wound have not yet completed the switch, the enameled wire between the pay-off end of the guide pay-off mechanism 2 and the clamping end of the clamping mechanism 4 is in a loose state. However, when the end of the enameled wire is clamped into the wire clamping piece 801, if the enameled wire If the enameled wire is in a loose state, it is difficult to clamp the enameled wire in the wire clamping piece 801, and even if the enameled wire is clamped in the wire clamping piece 801, when winding, if the enameled wire is in a loose state, the wound enameled wire will also be in a loose state, affecting normal winding. For this reason, the present invention proposes a tensioning mechanism 10, which is used to ensure that the enameled wire between the slide 301 and the clamping end of the clamping mechanism 4 is in a tensioned state when the end of the enameled wire is clamped in the wire clamping piece 801 and when the enameled wire is wound.

[0050] For details, please refer to the attached manual. Figure 8 A tensioning mechanism 10 is also provided in the slide 301, and the tensioning mechanism 10 includes a through opening 1001, which is opened in the slide 301, and a wire hole 3011 is opened on the slide 301. The enameled wire passes through the slide 301 through the wire hole 3011, and the through opening 1001 is connected to the wire hole 3011. A driving member 5 1002 is installed on one side of the slide 301, and the output end of the driving member 5 1002 extends into the through opening 1001 and is installed with a bidirectional screw rod 1003. Two slides 1004 are connected with threads on the bidirectional screw rod 1003. Rollers 1005 are provided on the two slides 1004, and the enameled wire is located between the two rollers 1005.

[0051] It should be noted that the driving part 5 1002 is a motor, which drives the bidirectional screw 1003 to rotate, so that it is connected to the bidirectional screw 1003 through the threads of the two slides 1004, so that the two slides 1004 drive the two rollers 1005 to move close to each other, and clamp the enameled wire between the two rollers 1005, so that before the enameled wire is cut, the enameled wire is squeezed by the two rollers 1005 to ensure that the enameled wire between the slide 301 and the clamping mechanism 4 is in a tensioned state.

[0052] In the above technical solution, when the enameled wire is clamped into the wire clamping piece 801 by the tensioning mechanism 10, the enameled wire is ensured to be in a tensioned state between the slide 301 and the clamping end of the clamping mechanism 4. In order to ensure the tight winding of the enameled wire, it is also necessary to ensure that the enameled wire is in a tensioned state during the winding process. However, during the switching process between the winding roller 1 that has completed winding and the winding roller 1 to be wound, since the guide wire-releasing mechanism 2 is always in a uniform speed wire-releasing state, the enameled wire between the outlet end of the guide wire-releasing mechanism 2 and the slide 301 is not subject to any tension. The wire is in a loose state due to the force applied. In order to ensure the tension of the winding, the winding of the winding roller 1 must be accelerated, and the enameled wire between the slide 301 and the winding roller 1 is in a tensioned state. However, there are currently two major problems in the processing of ultra-fine copper alloy wires. One is that it must undergo multiple deformation and annealing, which not only increases the cost but also makes it easy for wire breakage to occur during the process. The other is that the process is difficult to control and improper annealing may result in performance degradation. Therefore, an online heating method is currently generally used to heat the pure copper wire with a deformation of more than 80% for annealing. Warm processing makes the copper wire maintain a certain deformation stress and have good ductility. At this time, the enameled wire between the slide 301 and the winding roller 1 is in a tensioned state. When the winding of the winding roller 1 is accelerated, the enameled wire is affected by the warm processing and its ductility is enhanced. The winding speed of the winding roller 1 is accelerated, which means that the tension of the enameled wire between the slide 301 and the winding roller 1 becomes larger. Two phenomena will occur. One is that the clamping force of the wire clamping piece 801 is large enough to stretch the enameled wire between the slide 301 and the wire clamping piece 801. The other is that the clamping force of the wire clamping piece 801 is large enough to stretch the enameled wire between the slide 301 and the wire clamping piece 801. The first is that the clamping force of the wire clamping piece 801 is insufficient, causing the enameled wire clamped by the wire clamping piece 801 to slip off, but 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 slide 301 and the winding roller 1 by air cooling during winding, so as to solve the problem that the enameled wire is affected by temperature processing and its ductility is enhanced, resulting in the tension of the enameled wire between the slide 301 and the winding roller 1 becoming larger when the winding speed of the winding roller 1 is accelerated, thereby affecting the normal winding.

[0053] For details, please refer to the attached manual. Figure 9 The wire-taking device also includes a cooling mechanism 11, which includes two fixed boxes 1101. Two piston plates 1102 are installed on one side of the slide 301. The two piston plates 1102 are slidably and sealedly connected to the corresponding fixed boxes 1101. The two fixed boxes 1101 are each provided with an air inlet and an air outlet, and a one-way valve is provided in the air inlet and the air outlet. The outlet ends of the two air outlets are connected with a connecting pipe 1103. Two air outlet pipes 1104 are provided on the slide 301. The two connecting pipes 1103 are connected to the corresponding air outlet pipes 1104. A plurality of air outlet holes 1141 are provided on the air outlet pipe 1104, and the air outlet ends of the air outlet holes 1141 point toward the enameled wire.

[0054] It should be noted that during the winding process of the winding roller 1, the slide 301 is driven to move back and forth by the reciprocating mechanism 3 to achieve the tight arrangement and winding of the enameled wire. At the same time, the slide 301 can drive the two piston plates 1102 to slide back and forth in the corresponding fixed box 1101. When the piston plate 1102 slides back and forth in the fixed box 1101, air can be drawn into the fixed box 1101 through the one-way valve arranged in the air inlet, and through the reciprocating sliding of the piston plate 1102, the air drawn into the fixed box 1101 passes through the one-way valve in the air outlet, and is sent into the air outlet pipe 1104 through the connecting pipe 1103, and is blown to the enameled wire between the slide 301 and the winding roller 1 through the air outlet hole 1141 opened on the air outlet pipe 1104, thereby achieving the cooling of the enameled wire.

[0055] It should also be noted that in order to solve the problem of increasing the winding speed of the winding roller 1, which will cause the tension of the enameled wire between the slide 301 and the winding roller 1 to increase, the distance between the slide 301 and the winding roller 1 can also be shortened (for example, by setting the slide 301 into two parts, the upper part can move linearly along the axial direction of the winding roller 1 on the lower part, and the wire hole 3011 is set in the upper part of the slide 301, and the cylinder is used to push the upper part toward 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 slide 301 and the winding roller 1, so as to solve the problem of increasing the tension of the enameled wire due to the increase in the winding speed of the winding roller 1.

[0056] In the above technical solution, an air outlet duct 1104 is provided on both sides of the enameled wire between the slide 301 and the winding roller 1 to blow air to cool the enameled wire. However, due to the shape of the winding roller 1, both ends of the winding roller 1 are higher than the middle surface height of the winding roller 1. Therefore, the air outlet duct 1104 will hinder its winding during the winding process. For this reason, the present invention proposes an adjustment mechanism 12, so that during the winding process, when the air outlet duct 1104 contacts the end of the winding roller 1, the air outlet duct 1104 can swing to avoid the air outlet duct 1104 affecting its normal winding.

[0057] For details, please refer to the attached manual. Figure 10 An adjustment mechanism 12 is also provided on the slide 301. The adjustment mechanism 12 includes a groove 1201 opened on the slide 301. Two hinged plates 1202 are hinged in the groove 1201, and a fixed block 1203 is fixed in the groove 1201. Elastic parts 1204 are provided between the two hinged plates 1202 and the fixed block 1203.

[0058] It should be noted that the elastic member 1204 is a spring. When the slide 301 drives the air outlet pipe 1104 to move, when the air outlet pipe 1104 contacts the end of the winding roller 1, the air outlet pipe 1104 can be squeezed by the end of the winding roller 1, causing the hinged plate 1202 to swing and stretch the spring, thereby solving the problem of the air outlet pipe 1104 hindering normal winding.

[0059] It should also be noted that the air outlet holes 1141 are arranged to be distributed along the axial direction of the air outlet pipe 1104, so that when the hinged plate 1202 drives the air outlet pipe 1104 to swing, air can still be blown to the enameled wire to cool it down.

[0060] Further, refer to the instructions attached Figure 2 The reciprocating mechanism 3 also includes a base 302, on which a driving member 303 is installed. A reciprocating screw rod 304 is installed at the output end of the driving member 303, and the slide 301 is threadedly connected to the reciprocating screw rod 304.

[0061] It should be noted that the driving member 1 303 is a motor, which drives the driving member 1 303 to rotate, so that the driving member 1 303 is connected to the slide 301 through the threaded connection, so that the slide 301 can be driven to move back and forth.

[0062] Further, refer to the instructions attached Figure 3 The clamping mechanism 4 includes a fixed seat 401, and the output end of the telescopic component 7 is fixedly connected to the fixed seat 401. A driving member 2 402 is installed on the fixed seat 401. Two circular shafts 403 are installed on the output end of the driving member 2 402, and two clamping blocks 404 are slidably provided on the fixed seat 401. Guide holes 4041 are provided on the two clamping blocks 404. The two circular shafts 403 are slidably set in the corresponding guide holes 4041, and an elastic member 1 405 is provided between the two clamping blocks 404.

[0063] It should be noted that the driving member 402 is a cylinder and the elastic member 405 is a spring. The cylinder drives the two circular shafts 403 to move in the corresponding guide holes 4041, so that the circular shafts 403 push the two clamping blocks 404 to move closer and squeeze the spring so that the two clamping blocks 404 can clamp the enameled wire.

[0064] Further, refer to the instructions attached Figure 4 The thread trimming mechanism 5 includes two coaxially hinged blades 501 , and both blades 501 are provided with notches 502 , and the two circular shafts 403 are movably connected in the corresponding notches 502 .

[0065] It should be noted that, when the second driving member 402 drives the two circular shafts 403 to move, the two circular shafts 403 can push the two blades 501 to cut the enameled wire.

[0066] It should also be noted that if Figure 3 As shown, the shape of the guide hole 4041 is set. After the two clamping blocks 404 move close to each other and clamp the enameled wire, the driving member 402 continues to drive the two circular shafts 403 to move, so that the two circular shafts 403 can drive the two blades 501 to cut the enameled wire, thereby achieving the effect of clamping the enameled wire first and then cutting it.

[0067] Further, refer to the instructions attached Figure 1 The loading and unloading mechanism 6 includes a driving member 3 601, and a receiving hopper 602 is installed at the output end of the driving member 3 601. The receiving hopper 602 is used to place the winding roller 1 to be wound and the winding roller 1 after winding is completed.

[0068] It should be noted that the driving component 3 601 is a cylinder, which drives the receiving hopper 602 to extend to the bottom of the winding roller 1 to realize automatic loading and unloading of the winding roller 1.

[0069] Further, refer to the instructions attached Figure 5 、 Figure 11 as well as Figure 12 The wire-taking device also includes a fixing mechanism 13, which includes a bracket 1301, a mounting seat 1302 is rotatably provided on the bracket 1301, a driving member 1303 is installed on the bracket 1301, the output end of the driving member 1303 is rotatably connected to a connecting shaft 1304, the connecting shaft 1304 is slidably provided in the mounting seat 1302, a sliding sleeve 1305 is slidably provided on the mounting seat 1302, a plurality of hinged rods 1306 are hingedly provided on the sliding sleeve 1305, and the ends of the plurality of hinged rods 1306 away from the sliding sleeve 1305 are hingedly connected to a support plate 1307, and the plurality of support plates 1307 are all slidably provided on the mounting seat 1302.

[0070] It should be noted that the fixing mechanism 13 is a cylinder. When unloading the winding roller 1, the cylinder is first used to push the sleeve 1305 to slide on the mounting seat 1302, so that it drives the multiple abutment plates 1307 to contract through multiple hinged rods 1306, thereby releasing the fixation of the winding roller 1, and then the winding roller 1 is unloaded through the loading and unloading mechanism 6. When loading, the winding roller 1 is first placed on the mounting seat 1302 in a straight line through the loading and unloading mechanism 6, and then the sleeve 1305 is driven by the cylinder to contract and reset, so that the multiple abutment plates 1307 can reset and abut against the inner wall of the winding roller 1, thereby completing the fixation of the winding roller 1 and realizing the loading of the winding roller 1.

[0071] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
