Description

Technical Field

[0001] The present invention relates to the technical field of silver-plated copper wire processing, and particularly relates to an electroplating post-treatment device and a treatment method for silver-plated copper wire. Background Art

[0002] Silver-plated copper wire is a thin wire formed by plating silver on the surface of oxygen-free copper wire or low-oxygen copper wire and then drawing it thinner by a wire drawing machine. It has excellent electrical conductivity, thermal conductivity, corrosion resistance, and high-temperature oxidation resistance, and is applied in the fields of electronics, communication, aerospace, etc.

[0003] The invention patent with the authorized publication number CN 114525561 B discloses an electroplating post-treatment process for silver-plated copper wire, which relates to the field of silver-plated copper wire. In this post-treatment process, several wire drawing wheels in the electroplating post-treatment device are used to stretch the silver-plated copper wire to produce silver-plated copper wire products with different diameters. During the process of stretching the silver-plated copper wire by the wire drawing wheels, a passivation mechanism is used to passivate it to form a protective film on its surface. Then, the washing mechanism removes the residual silver-plated copper wire passivation solution, and then it is dried to make a silver-plated copper wire product. This silver-plated copper wire product is formed by one-time stretching, avoiding the stretching instability caused by multiple stretchings, and thus avoiding the defects of uneven thickness and unstable quality of the silver-plated copper wire product. Moreover, a protective film is continuously formed on the surface of this silver-plated copper wire product, ensuring that a dense protective film is formed everywhere on the silver-plated copper wire product, and protecting the silver-plated copper wire product from discoloration and deterioration for a long time.

[0004] However, after the above process is actually applied by those skilled in the art, it is found that there are still some disadvantages. More obvious is that when processing the silver-plated copper wire, the technician not only needs to pass the silver-plated copper wire through the spray chamber through the inlet hole, but also needs to wind the silver-plated copper wire around each wire drawing wheel once, and finally pass it through the drying cylinder and pass it out through the outlet and wind it on the winding roller of the winding mechanism.

[0005] The above process causes the silver-plated copper wire initially wound on the winding roller to be unable to be effectively stretched and rinsed. Therefore, this part of the silver-plated copper wire is unqualified. To avoid affecting the quality of the subsequent finished products, the technician needs to cut it off after winding this part of the silver-plated copper wire and remove it from the winding roller or directly replace the winding roller. The operation is cumbersome, wasting manpower and reducing the processing efficiency of the silver-plated copper wire. Its applicability for industrial processing needs to be improved.

[0006] Therefore, it is very necessary to invent an electroplating post-treatment device and a treatment method for silver-plated copper wire to solve the above problems. Summary of the Invention

A torsion spring is fixedly connected to the rear side of the annular reset plate and is fixedly connected with the back plate. The L-shaped plate is fixedly arranged on the top of the front of the annular sleeve plate. The hydraulic cylinder is fixedly arranged on the top of the L-shaped plate. The pressing plate is located at the bottom of the L-shaped plate and is fixedly connected with the output shaft of the hydraulic cylinder.

[0014] Preferably, the first reciprocating screw is rotationally nested on the front of the back plate through a bearing. The transverse slider is sleeved outside the first reciprocating screw and is threadedly connected to the first reciprocating screw. There are two first guide rods, and the two first guide rods respectively slide through the two sides of the front of the transverse slider and are fixedly connected to the back plate. The guide ring is fixedly arranged on the top of the transverse slider.

[0015] Preferably, the cutting mechanism includes a base, a top plate, a first spring, a connecting block, a lifting plate and a cutter;

[0016] The base and the top plate are both fixedly arranged on the front of the back plate. The top plate is located above the base. There are two first springs and two connecting blocks. The two first springs are respectively fixedly connected to the two sides of the bottom of the top plate. The two connecting blocks are respectively fixedly connected to the bottom ends of the two first springs. The lifting plate is fixedly arranged between the two connecting blocks and is slidably nested on the back plate. The cutter is fixedly arranged at the bottom of the lifting plate.

[0017] Preferably, two second guide rods slide through the left side of the driving sleeve plate. The left ends of the two second guide rods are fixedly connected together to form a second mounting plate, and the second mounting plate is fixedly arranged on the rear side of the back plate.

[0018] Preferably, the triggering mechanism includes a sliding plate, a rotating ring, a second spring, a sliding rod and a triggering push block;

[0019] The sliding plate is slidably sleeved outside the two second guide rods. The rotating ring is rotationally nested on the right side of the sliding plate through a bearing. One end of the second spring is fixedly connected to the sliding plate and the other end is fixedly connected to the threaded sleeve. The sliding rod is fixedly arranged at the top of the right side of the sliding plate. The triggering push block is fixedly arranged at the right end of the sliding rod.

[0020] The present invention also provides a post-treatment method for electroplated silver-coated copper wires, which is realized by using the above-mentioned post-treatment equipment for electroplated silver-coated copper wires. The method specifically includes the following steps:

[0021] S1. Pass the silver-coated copper wire through the stretching, passivation and washing mechanism from the left side, then pass it out from the right side of the stretching, passivation and washing mechanism, and make its end fit on the surface of the winding roller outside the second driving shaft. Then, make the hydraulic cylinder in the wire end fixing mechanism outside the second driving shaft drive the pressing plate to descend, so as to press the end of the silver-coated copper wire on the surface of the winding roller outside the second driving shaft;

[0022] S2. Start the drive motor. After the drive motor starts, it drives the second reciprocating lead screw to rotate. When the second reciprocating lead screw rotates, it continuously drives the first worm to rotate. When the first worm rotates, it drives the first reciprocating screw to continuously rotate through the worm gear outside the first reciprocating screw. The first reciprocating screw then drives the guide ring to continuously move back and forth through the transverse slider. When the guide ring moves back and forth, it drives the silver-plated copper wire passing through it to move back and forth synchronously;

[0023] S3. When the second reciprocating lead screw rotates, it drives the second worm to rotate through the drive sleeve plate and the drive rod. The second worm then drives the worm gear outside the second drive shaft to rotate. This worm gear drives the winding roller outside the second drive shaft to rotate synchronously through the second drive shaft. At this time, the end of the silver-plated copper wire is pressed against the surface of the winding roller outside the second drive shaft. When the winding roller outside the second drive shaft rotates, it winds the silver-plated copper wire through the end of the silver-plated copper wire. When this winding roller rotates, it drives the wire end fixing mechanism outside it to rotate synchronously;

[0024] S4. When the second worm rotates, the second reciprocating lead screw continuously drives the threaded sleeve, thereby causing the threaded sleeve to continuously move to the right. When the threaded sleeve moves to the right, it pulls the sliding plate through the second spring, thereby causing the sliding plate to drive the trigger push block to move to the right synchronously through the sliding rod. During the process of the trigger push block moving to the right, it continuously pushes the lifting plate downward;

[0025] S5. When the moving distance of the threaded sleeve reaches the first threshold, the second worm no longer drives the worm gear outside the second drive shaft under the drive of the threaded sleeve. At this time, the untreated silver-plated copper wire is completely wound. And because the winding roller outside the second drive shaft no longer winds the silver-plated copper wire, the silver-plated copper wire is in a static state. At this time, the torsion spring in the wire end fixing mechanism outside the second drive shaft drives the wire end fixing mechanism to reset, and at the same time, the wire end fixing mechanism outside the first drive shaft is used to press the silver-plated copper wire against the surface of the winding roller outside the first drive shaft;

[0026] S6. When the moving distance of the threaded sleeve reaches the second threshold, the trigger push block drives the cutting knife to cut off the silver-plated copper wire through the lifting plate. As the threaded sleeve continues to move, when the moving distance of the threaded sleeve reaches the third threshold, the second worm starts to drive the worm gear outside the first drive shaft, thereby causing the first drive shaft to drive the winding roller outside it to wind the silver-plated copper wire processed by the stretching, passivation, and washing mechanism;

[0027] S7. When the number of rotations of the winding roller outside the first drive shaft reaches the threshold, the wire end fixing mechanism outside the first drive shaft is reset. At this time, under the drive of the threaded sleeve, the second worm continuously moves to the right. When the threaded sleeve moves to the rightmost end of the reciprocating thread outside the second reciprocating lead screw, the threaded sleeve starts to drive the second worm to move to the left. When the threaded sleeve drives the second worm to no longer mesh with the worm gear outside the first drive shaft, the silver-plated copper wire winding is completed at this time.

[0028] Technical effects and advantages of the present invention:

[0029] The present invention is provided with a second drive shaft, a lateral swing mechanism, a cutting mechanism, a multiple drive mechanism and a trigger mechanism, so as to drive the second drive shaft and the lateral swing mechanism by using the multiple drive mechanism. Furthermore, the second drive shaft drives the winding roller to wind the silver-plated copper wire that has not been processed by the stretching, passivation and washing mechanism. The lateral swing mechanism drives the wound silver-plated copper wire to avoid fixed areas and wind evenly on the outer side of the winding roller. At the same time, the multiple drive mechanism can also drive the trigger mechanism, so that the trigger mechanism drives the cutting mechanism to automatically cut off the silver-plated copper wire after the unprocessed silver-plated copper wire is wound. Finally, the multiple drive mechanism can drive the first drive shaft to complete the winding of the qualified silver-plated copper wire. Compared with the same type of devices or processes in the prior art, the present invention can wind the unprocessed silver-plated copper wire and the qualified silver-plated copper wire separately, thus avoiding the quality problems of the finished products caused by synchronous winding. At the same time, the collected unprocessed silver-plated copper wire can be centrally processed later, reducing the operation difficulty, saving manpower and improving the processing efficiency of the silver-plated copper wire, and being more suitable for industrial production.

Detailed implementation mode

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention provides a post-treatment device for electroplated silver copper wire as shown in Figures 1-6 Figure 10, including a stretching, passivating and washing mechanism. A back plate 1 is fixedly arranged on the right side of the stretching, passivating and washing mechanism. The front surface of the back plate 1 is rotationally nested with a first drive shaft 2 and a second drive shaft 3 through bearings. Winding rollers 4 are slidably nested on the outer sides of both the first drive shaft 2 and the second drive shaft 3. Wire head fixing mechanisms 5 are arranged on the outer sides of both the winding rollers 4. A lateral swing mechanism 6 is arranged on the left side of the front surface of the back plate 1. A cutting mechanism 7 is arranged on the right side of the front surface of the back plate 1. The cutting mechanism 7 is located between the two wire head fixing mechanisms 5. A multiple drive mechanism 8 is arranged on the rear side of the back plate 1. A trigger mechanism 9 is arranged on the multiple drive mechanism 8.

[0039] As shown in Figure 3As shown, the wire-end fixing mechanism 5 includes an annular sleeve plate 51, an annular reset plate 52, an L-shaped plate 53, a hydraulic cylinder 54, and a pressing plate 55. Among them, the annular sleeve plate 51 is rotatably nested on the front of the back plate 1 through a bearing. The annular reset plate 52 is fixedly arranged inside the annular sleeve plate 51. A torsion spring is fixedly connected to the rear side of the annular reset plate 52, and the torsion spring is fixedly connected to the back plate 1. The L-shaped plate 53 is fixedly arranged at the top of the front of the annular sleeve plate 51. The hydraulic cylinder 54 is fixedly arranged on the top of the L-shaped plate 53. The pressing plate 55 is located at the bottom of the L-shaped plate 53 and is fixedly connected to the output shaft of the hydraulic cylinder 54.

[0040] By setting the above structure, after the end of the silver-plated copper wire is placed on the top of the winding roller 4, the hydraulic cylinder 54 drives the pressing plate 55 to descend, so as to press the end of the silver-plated copper wire against the top of the winding roller 4. When the winding roller 4 rotates subsequently, the annular sleeve plate 51 can be driven to rotate synchronously through the pressing plate 55, the hydraulic cylinder 54, and the L-shaped plate 53, so that the end of the silver-plated copper wire is continuously fixed. When the silver-plated copper wire is wound several times, the hydraulic cylinder 54 can be driven to drive the pressing plate 55 to reset. At this time, the whole wire-end fixing mechanism 5 is reset under the drive of the torsion spring on the rear side of the annular reset plate 52.

[0041] As Figure 4 shown, the lateral swing mechanism 6 includes a first reciprocating screw 61, a lateral slider 62, a first guide rod 63, and a guide ring 64. Among them, the first reciprocating screw 61 is rotatably nested on the front of the back plate 1 through a bearing. The lateral slider 62 is sleeved outside the first reciprocating screw 61 and is threadedly connected to the first reciprocating screw 61. There are two first guide rods 63. The two first guide rods 63 respectively penetrate through the two sides of the front of the lateral slider 62 and are fixedly connected to the back plate 1. The guide ring 64 is fixedly arranged on the top of the lateral slider 62.

[0042] By setting the above structure, when the first reciprocating screw 61 rotates continuously, the first reciprocating screw 61 drives the guide ring 64 to move back and forth continuously through the lateral slider 62. When the guide ring 64 moves back and forth, the silver-plated copper wire passing through is driven to move back and forth synchronously. Thus, while the silver-plated copper wire is evenly wound around the outside of the winding roller 4, the silver-plated copper wire can also avoid the area pressed by the pressing plate 55, thereby preventing the silver-plated copper wire from winding around the outside of the pressing plate 55 and causing the pressing plate 55 to be unable to be recycled.

[0043] As Figure 5As shown, the cutting mechanism 7 includes a base 71, a top plate 72, a first spring 73, a connecting block 74, a lifting plate 75 and a cutter 76, wherein the base 71 and the top plate 72 are both fixedly arranged on the front side of the back plate 1, the top plate 72 is located at the top of the base 71, two first springs 73 and two connecting blocks 74 are each provided, the two first springs 73 are respectively fixedly connected to the two sides of the bottom of the top plate 72, the two connecting blocks 74 are respectively fixedly connected to the bottom ends of the two first springs 73, the lifting plate 75 is fixedly arranged between the two connecting blocks 74, and is slidably nested on the back plate 1, and the cutter 76 is fixedly arranged at the bottom of the lifting plate 75.

[0044] By setting the above structure, when the lifting plate 75 is pressed down, the cutter 76 can be driven to descend synchronously, thereby cutting the silver-plated copper wire. At the same time, when the lifting plate 75 descends, the first spring 73 is stretched through the connecting block 74, and then when the lifting plate 75 is no longer pressed down, the first spring 73 can drive the lifting plate 75 to reset through the connecting block 74.

[0045] like Figure 2 and Figure 6 As shown, the multi-drive mechanism 8 includes a first mounting plate 81, a drive motor 82, a second reciprocating screw 83, a first worm 84, a threaded sleeve 85, a second worm 86, a drive rod 87, a drive sleeve 88 and a plurality of worm wheels 89, wherein the first mounting plate 81 is fixedly arranged on the rear side of the back plate 1, the drive motor 82 is fixedly arranged on the outside of the first mounting plate 81, the second reciprocating screw 83 is located on the inside of the first mounting plate 81 and is transmission-connected to the drive motor 82, the first worm 84 is fixedly sleeved on the outside of the second reciprocating screw 83, the threaded sleeve 85 is sleeved on the outside of the second reciprocating screw The second worm gear 86 is rotatably sleeved on the outside of the threaded sleeve 85 through a bearing. Two drive rods 87 are provided. Both drive rods 87 are slidably penetrated and arranged on the right side of the second worm gear 86. The drive sleeve plate 88 is fixedly sleeved on the outside of the second reciprocating screw rod 83 and is fixedly connected to the two drive rods 87. The multiple worm gears 89 are respectively fixedly sleeved on the outer rear end of the second drive shaft 3, the outer rear end of the first drive shaft 2 and the outer rear end of the first reciprocating screw rod 61.

[0046] By setting the above structure, it is convenient for the driving motor 82 to drive the first worm 84 to rotate through the second reciprocating lead screw 83, and then drive the worm wheel 89 engaged with the first worm 84. At the same time, the second reciprocating lead screw 83 can drive the second worm 86 to continuously rotate through the driving sleeve plate 88 and the driving rod 87, and then drive the worm wheel 89 engaged with the second worm 86. At the same time, the second reciprocating lead screw 83 can also drive the second worm 86 to move left and right through the threaded sleeve 85, so as to adjust the worm wheel 89 engaged with the second worm 86.

[0047] As Figure 6 shown, two second guide rods 851 are slidably penetrated through the left side of the driving sleeve plate 88, and a second mounting plate 852 is fixedly arranged at the left ends of the two second guide rods 851, and the second mounting plate 852 is fixedly arranged at the rear side of the back plate 1.

[0048] By setting the above structure, it is convenient to limit the threaded sleeve 85 by using the second guide rod 851 and the second mounting plate 852, so that the second reciprocating lead screw 83 can drive the threaded sleeve 85 to move, rather than drive the threaded sleeve 85 to rotate.

[0049] As Figure 6 shown, the triggering mechanism 9 includes a sliding plate 91, a rotating ring 92, a second spring 93, a sliding rod 94 and a triggering push block 95. Among them, the sliding plate 91 is slidably sleeved outside the two second guide rods 851, the rotating ring 92 is rotatably nested on the right side of the sliding plate 91 through a bearing, one end of the second spring 93 is fixedly connected with the sliding plate 91 and the other end is fixedly connected with the threaded sleeve 85, the sliding rod 94 is fixedly arranged at the top of the right side of the sliding plate 91, and the triggering push block 95 is fixedly arranged at the right end of the sliding rod 94.

[0050] By setting the above structure, when the threaded sleeve 85 moves, it can drive the rotating ring 92 to move synchronously through the second spring 93, so that the sliding plate 91 drives the triggering push block 95 to move synchronously through the sliding rod 94. After the triggering push block 95 moves, it can press down the lifting plate 75, so that the lifting plate 75 drives the cutting knife 76 to cut off the silver-plated copper wire. At the same time, the setting of the rotating ring 92 can prevent the sliding plate 91 from directly contacting the driving rod 87. When the driving rod 87 contacts the rotating ring 92, it can drive the rotating ring 92 to rotate synchronously, so as to prevent the movement of the sliding plate 91 from affecting the rotation of the driving rod 87.

[0051] The present invention also provides a post-treatment method for electroplated silver-plated copper wire, which is realized by using the above-mentioned post-treatment equipment for electroplated silver-plated copper wire. The method specifically includes the following steps:

[0052] S1. Pass the silver-plated copper wire through the stretching, passivation and washing mechanism from the left side, then pass it out from the right side of the stretching, passivation and washing mechanism, and make its end fit on the surface of the winding roller 4 outside the second drive shaft 3. Subsequently, drive the pressing plate 55 to descend by the hydraulic cylinder 54 in the wire end fixing mechanism 5 outside the second drive shaft 3, so as to press the end of the silver-plated copper wire on the surface of the winding roller 4 outside the second drive shaft 3;

[0053] S2. Start the drive motor 82. After the drive motor 82 starts, it drives the second reciprocating lead screw 83 to rotate. When the second reciprocating lead screw 83 rotates, it continuously drives the first worm 84 to rotate. When the first worm 84 rotates, it drives the first reciprocating screw 61 to continuously rotate through the worm wheel 89 outside the first reciprocating screw 61. The first reciprocating screw 61 drives the guide ring 64 to continuously move back and forth through the transverse slider 62. When the guide ring 64 moves back and forth, it drives the passed silver-plated copper wire to move back and forth synchronously;

[0054] S3. When the second reciprocating lead screw 83 rotates, it drives the second worm 86 to rotate through the drive sleeve plate 88 and the drive rod 87. The second worm 86 drives the worm wheel 89 outside the second drive shaft 3 to rotate. This worm wheel 89 drives the winding roller 4 outside the second drive shaft 3 to rotate synchronously through the second drive shaft 3. At this time, the end of the silver-plated copper wire is pressed on the surface of the winding roller 4 outside the second drive shaft 3. When the winding roller 4 outside the second drive shaft 3 rotates, it winds the silver-plated copper wire through the end of the silver-plated copper wire. When the winding roller 4 rotates, it drives the wire end fixing mechanism 5 outside it to rotate synchronously;

[0055] S4. When the second worm 86 rotates, the second reciprocating lead screw 83 continuously drives the threaded sleeve 85, so that the threaded sleeve 85 continuously moves to the right. When the threaded sleeve 85 moves to the right, it pulls the sliding plate 91 through the second spring 93, so that the sliding plate 91 drives the trigger push block 95 to move to the right synchronously through the sliding rod 94. During the process of the trigger push block 95 moving to the right, it continuously pushes the lifting plate 75 downward;

[0056] S5. When the moving distance of the threaded sleeve 85 reaches the first threshold value, the second worm 86 no longer drives the worm wheel 89 outside the second drive shaft 3 under the drive of the threaded sleeve 85. At this time, the untreated silver-plated copper wire is completely wound. And because the winding roller 4 outside the second drive shaft 3 no longer winds the silver-plated copper wire, the silver-plated copper wire is in a static state. At this time, the torsion spring in the wire end fixing mechanism 5 outside the second drive shaft 3 drives the wire end fixing mechanism 5 to reset, and at the same time, the wire end fixing mechanism 5 outside the first drive shaft 2 is used to press the silver-plated copper wire on the surface of the winding roller 4 outside the first drive shaft 2;

[0057] S6. When the moving distance of the threaded sleeve 85 reaches the second threshold value, it triggers the push block 95 to push the cutting tool 76 through the lifting plate 75 to cut off the silver-plated copper wire. As the threaded sleeve 85 continues to move, when the moving distance of the threaded sleeve 85 reaches the third threshold value, the second worm 86 starts to drive the worm wheel 89 outside the first drive shaft 2, so that the first drive shaft 2 drives the winding roller 4 outside it to wind the silver-plated copper wire processed by the stretching, passivation and washing mechanism;

[0058] S7. When the number of rotations of the winding roller 4 outside the first drive shaft 2 reaches the threshold value, the wire fixing mechanism 5 outside the first drive shaft 2 is reset. At this time, driven by the threaded sleeve 85, the second worm 86 continues to move to the right. When the threaded sleeve 85 moves to the rightmost end of the reciprocating thread on the outside of the second reciprocating lead screw 83, the threaded sleeve 85 starts to drive the second worm 86 to move to the left. When the threaded sleeve 85 drives the second worm 86 to no longer mesh with the worm wheel 89 outside the first drive shaft 2, the winding of the silver-plated copper wire is completed at this time.

[0059] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

7. A post-treatment method for electroplated silver-coated copper wire, characterized in that, Implemented by using an electroplating post-treatment device for silver-plated copper wires as described in claim 6. The method specifically includes the following steps: S1. Pass the silver-plated copper wire through the stretching, passivation and washing mechanism from the left side, and then pass it out from the right side of the stretching, passivation and washing mechanism, and make its end fit on the surface of the winding roller on the outer side of the second driving shaft. Subsequently, drive the pressing plate to descend by the hydraulic cylinder in the wire end fixing mechanism on the outer side of the second driving shaft, so as to press the end of the silver-plated copper wire on the surface of the winding roller on the outer side of the second driving shaft. S2. Start the driving motor. After the driving motor starts, drive the second reciprocating screw rod to rotate. When the second reciprocating screw rod rotates, it continuously drives the first worm to rotate. When the first worm rotates, it drives the first reciprocating screw rod to continuously rotate through the worm gear on the outer side of the first reciprocating screw rod. The first reciprocating screw rod drives the guiding ring to continuously move back and forth through the transverse slider. When the guiding ring moves back and forth, it drives the passed silver-plated copper wire to move back and forth synchronously. S3. When the second reciprocating screw rod rotates, it drives the second worm to rotate through the driving sleeve plate and the driving rod. The second worm drives the worm gear on the outer side of the second driving shaft to rotate. This worm gear drives the winding roller on the outer side of the second driving shaft to rotate synchronously through the second driving shaft. At this time, the end of the silver-plated copper wire is pressed on the surface of the winding roller on the outer side of the second driving shaft. When the winding roller on the outer side of the second driving shaft rotates, it winds the silver-plated copper wire through the end of the silver-plated copper wire. When this winding roller rotates, it drives the wire end fixing mechanism on its outer side to rotate synchronously. S4. When the second worm rotates, the second reciprocating screw rod continuously drives the threaded sleeve, so that the threaded sleeve continuously moves to the right. When the threaded sleeve moves to the right, it pulls the sliding plate through the second spring, so that the sliding plate drives the triggering push block to move to the right synchronously through the sliding rod. During the rightward movement of the triggering push block, it continuously pushes the lifting plate downward. S5. When the moving distance of the threaded sleeve reaches the first threshold, the second worm no longer drives the worm gear outside the second drive shaft under the drive of the threaded sleeve. At this time, the untreated silver-plated copper wire is completely wound up. And since the winding roller outside the second drive shaft no longer winds the silver-plated copper wire, the silver-plated copper wire is in a static state. At this time, the torsion spring in the wire head fixing mechanism outside the second drive shaft drives the wire head fixing mechanism to reset, and at the same time, the wire head fixing mechanism outside the first drive shaft is used to press the silver-plated copper wire against the surface of the winding roller outside the first drive shaft; S6. When the moving distance of the threaded sleeve reaches the second threshold, the trigger block pushes the cutting knife through the lifting plate to cut off the silver-plated copper wire. As the threaded sleeve continues to move, when the moving distance of the threaded sleeve reaches the third threshold, the second worm starts to drive the worm gear outside the first drive shaft, so that the first drive shaft drives the winding roller outside it to wind the silver-plated copper wire processed by the stretching, passivation and washing mechanism; S7. When the number of rotations of the winding roller outside the first drive shaft reaches the threshold, the wire head fixing mechanism outside the first drive shaft is reset. At this time, under the drive of the threaded sleeve, the second worm continues to move to the right. When the threaded sleeve moves to the rightmost end of the reciprocating thread on the outside of the second reciprocating lead screw, the threaded sleeve starts to drive the second worm to move to the left. When the threaded sleeve drives the second worm to no longer mesh with the worm gear outside the first drive shaft, the winding of the silver-plated copper wire is completed at this time.
