Description

Technical Field

[0001] This invention relates to the field of stranding technology, and more particularly to a stranding device and a stranding method. Background Technology

[0002] In the manufacturing process of electronic products, there is a need to strand conductors to enhance their electrical performance. For example, in the production of connectors, during conductor processing, to facilitate subsequent tinning and soldering of conductors composed of multiple fine metal wires, two conductors of the same type need to be twisted or stranded together to prevent the metal wires from bursting and causing a short circuit during tinning and soldering. More specifically, it is necessary to strand two red conductors and two blue conductors together.

[0003] In existing technology, the above operations can be achieved using a stranding machine. Specifically, a stranding machine has stranding claws and a motor that drives the stranding claws to rotate. The stranding claws clamp two conductors of the same color and then rotate under the control of the motor. Since one end of the conductors is fixed, the two conductors can be twisted together into a single strand. However, due to the small size of the connectors and the small gap between different types of conductors, when using a stranding machine in the existing technology, the stranding claws are prone to hitting adjacent conductors. In severe cases, this can cause adjacent conductors to deform and break apart, posing a risk of short circuit. Therefore, currently, for products with small gaps, stranding is usually done manually. However, manual stranding has problems such as low efficiency and high labor intensity.

[0004] Therefore, there is an urgent need for a device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a stranding device with high stranding efficiency and low labor intensity.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0007] A stranding device for stranding multiple conductors, the multiple conductors including a first conductor group and a second conductor group, the first conductor group and the second conductor group each including at least two conductors, including:

[0008] A conductor carrier for securing multiple conductors;

[0009] A conductor redirection mechanism includes a redirection drive and a redirection block driven by the redirection drive to move in the Z direction. The redirection block has a redirection groove for contacting at least two conductors of a first conductor group. The redirection drive pushes at least two conductors of the first conductor group to bend through the redirection groove, so that at least two conductors of the first conductor group bend at an angle to at least two conductors of a second conductor group.

[0010] An inclined stranding mechanism for stranding at least two conductors of the first conductor group;

[0011] A horizontal stranding mechanism for stranding at least two of the conductors of the second conductor group.

[0012] Optionally, it also includes a conductor limiting mechanism, which includes a limiting drive and a limiting block driven by the limiting drive to move in the Z direction. The limiting block has a first limiting groove disposed opposite to the redirecting groove in the Z direction, and the first limiting groove is used to limit the conductor after bending.

[0013] Optionally, the first limiting groove is a V-shaped groove, and the bottom of the V-shaped groove has an inclined guide surface.

[0014] Optionally, it further includes a reset mechanism, which includes a fixed block connected to the output end of the limit drive, a wire pressing assembly slidably connected to the fixed block, and an elastic element disposed between the fixed block and the wire pressing assembly. The wire pressing assembly can push the first stranded conductor group to move under the drive of the elastic element, so as to reset the first conductor group.

[0015] Optionally, the wire pressing assembly includes a Z-axis slider and a wire pressing bar. The fixing block has a sliding hole and a second limiting groove communicating with the sliding hole. One end of the Z-axis slider slides in the sliding hole, and one end of the Z-axis slider has a limiting structure slidably disposed in the second limiting groove. The elastic element is located in the sliding hole and abuts against one end of the Z-axis slider. The wire pressing bar is disposed at the other end of the Z-axis slider and is used to push the first conductor group to move. The second limiting groove is used to limit the lower limit of the movement of the limiting structure, so that the distance that the Z-axis slider drives the wire pressing bar to push the first conductor group to move is approximately equal to the distance that the first conductor group needs to move to reset.

[0016] Optionally, the conductor carrier can slide along the X direction, and during the sliding process, the stranded first conductor group is driven to pass through the pressure bar to be reset under the pressure of the pressure bar.

[0017] Optionally, the wire pressing assembly further includes a roller mounted on the other end of the Z-axis slider, and the roller is capable of rolling on the top surface of the conductor carrier.

[0018] Optionally, the redirection groove is an inverted trapezoidal groove, and the redirection block includes a block body and two supports disposed opposite to each other on the block body. The two supports cooperate with the block body to form the redirection groove, and the two supports have different heights.

[0019] Another object of the present invention is to provide a stranding method with high stranding efficiency.

[0020] Based on the above concept, the technical solution adopted by this invention is as follows:

[0021] The stranding method, applied to the aforementioned stranding equipment, includes the following steps:

[0022] S1. Fix multiple conductors to the conductor carrier, wherein at least two conductors of the first conductor group and at least two conductors of the second conductor group have residual inner sheaths at their ends;

[0023] S2. Control the reversing drive to move the reversing block in the Z direction, so that the first conductor group is located in the reversing groove, and push the first conductor group to bend through the reversing groove, so that at least two conductors of the first conductor group are bent at an angle to at least two conductors of the second conductor group.

[0024] S3. Control the tilting stranding mechanism to strand at least two conductors of the first conductor group. During the stranding of the first conductor group, control the tilting stranding mechanism to gradually retract, and remove the remaining inner sheath on the conductors of the first conductor group during the retraction.

[0025] S4. Control the horizontal stranding mechanism to strand at least two conductors of the second conductor group. During the stranding process of the second conductor group, control the horizontal stranding mechanism to gradually retract, and remove the remaining inner sheath on the conductors of the second conductor group during the retraction.

[0026] Optionally, the stranding device further includes a conductor limiting mechanism and a reset mechanism. Before step S2, the stranding method further includes the following steps:

[0027] The limiting drive of the conductor limiting mechanism drives the limiting block to move a preset distance in the Z direction, and pushes the roller to contact the top surface of the conductor carrier through the fixing block and Z-direction slider of the reset mechanism. The elastic element of the reset mechanism is squeezed into a contracted state.

[0028] After step S4, the stranding method further includes the following steps:

[0029] As the conductor carrier moves along the X direction, the roller rolls on the conductor carrier. After the roller rolls out of the conductor carrier, the elastic element pushes the Z-direction sliding block to move closer to the first conductor group, so as to push the first conductor group through the pressure bar until the limiting structure of the pressure assembly contacts the second limiting groove, so as to reset the first conductor group.

[0030] The beneficial effects of this invention are:

[0031] The stranding device and method provided by this invention include a conductor reorientation mechanism comprising a reorientation drive and a reorientation block. The reorientation block, driven by the reorientation drive, can bend at least two conductors of the first conductor group, thereby changing the X-direction extension of the at least two conductors to an extension direction intersecting both the X and Z directions. This adjusts the extension direction of the conductors in the first conductor group, resulting in a larger operating space around both the first and second conductor groups. This ensures that the inclined stranding mechanism does not touch the second conductor group when stranding the first conductor group, and the horizontal stranding mechanism does not touch the first conductor group when stranding the second conductor group. This achieves automatic stranding for situations with small conductor gaps, resulting in higher stranding efficiency, reduced operator workload, and more stable and reliable product quality.

[0049] Example 1

[0050] This embodiment provides a stranding device for stranding multiple conductors. The multiple conductors include a first conductor group 100 and a second conductor group 200, wherein each of the first conductor group 100 and the second conductor group 200 includes at least two conductors. In this embodiment, the two conductors of the first conductor group 100 and the two conductors of the second conductor group 200 are arranged sequentially along the Y direction. The multiple conductors also include other conductors located on the side of the first conductor group 100 away from the second conductor group 200. It should be noted that the multiple conductors can be conductors on a connector 300. The stranding device provided in this embodiment can be used for stranding products with small gaps between conductors, has high stranding efficiency, low labor intensity, and high stranding consistency, thus improving product quality.

[0051] like Figure 1 and Figure 2 As shown, the stranding equipment includes a conductor carrier 1, a conductor redirection mechanism 2, an inclined stranding mechanism 3, and a horizontal stranding mechanism 4.

[0052] The conductor carrier 1 is used to fix multiple conductors. In some embodiments, when the multiple conductors are conductors on the connector 300, the conductor carrier 1 in this embodiment fixes the conductors by fixing the connector 300. In this embodiment, the conductors extend along the X direction after being fixed.

[0053] like Figure 3 As shown, the conductor redirection mechanism 2 includes a redirection drive 21 and a redirection block 22 driven by the redirection drive 21 to move in the Z direction. Wherein, as... Figure 4As shown, the redirecting block 22 has a redirecting groove 221, which is disposed facing the conductor. In some embodiments, the redirecting block 22 is located below the conductor; in other embodiments, the redirecting block 22 is located above the conductor. This embodiment is not limited to this. In this embodiment, the redirecting block 22 is described as being located below the conductor. The redirecting groove 221 is used to contact at least two conductors of the first conductor group 100. The redirecting drive member 21 pushes at least two conductors of the first conductor group 100 to bend through the redirecting groove 221, so that at least two conductors of the first conductor group 100 are bent at an angle to at least two conductors of the second conductor group 200. That is, the first conductor group 100 is tilted up, thereby making at least two conductors of the first conductor group 100 and at least two conductors of the second conductor group 200 located on different planes, so that the stranded wires of the first conductor group 100 and the second conductor group 200 do not interfere with each other. It should be noted that the size of the redirecting block 22 in the Y direction should meet the minimum distance between the second conductor group 200 and other conductors in the Y direction, so that the redirecting block 22 will not collide with the second conductor group 200 and other conductors when pushing the first conductor group 100 to move, thereby improving the reliability of the conductor redirecting mechanism 2 in lifting the first conductor group 100.

[0054] The inclined stranding mechanism 3 is used to strand at least two conductors of the first conductor group 100. Specifically, the axis of the stranding claw of the inclined stranding mechanism 3 is parallel to the axis of the conductors of the first conductor group 100, facilitating the stranding of at least two conductors of the first conductor group 100. The specific structure of the inclined stranding mechanism 3 can be found in existing technology, including stranding claws and driving components for rotating or translating the stranding claws. These driving components include, but are not limited to, cylinders, motors, etc., and this embodiment does not limit this. The horizontal stranding mechanism 4 is used to strand at least two conductors of the second conductor group 200. The axis of the stranding claw of the horizontal stranding mechanism 4 is parallel to the axis of the conductors of the second conductor group 200, facilitating the stranding of at least two conductors of the second conductor group 200. The specific structure of the horizontal stranding mechanism 4 is the same as that of the inclined stranding mechanism 3, only the extension direction is different, and this embodiment will not elaborate further.

[0055] The stranding device provided in this embodiment includes a conductor redirection mechanism 2 comprising a redirection drive 21 and a redirection block 22. The redirection block 22 can bend at least two conductors of the first conductor group 100 under the drive of the redirection drive 21, thereby changing the extension of the at least two conductors along the X direction to an extension direction intersecting both the X and Z directions. This adjusts the extension direction of the conductors in the first conductor group 100, thereby providing a larger operating space around both the first conductor group 100 and the second conductor group 200. This ensures that the tilting stranding mechanism 3 will not touch the second conductor group 200 when stranding the first conductor group 100, and the horizontal stranding mechanism 4 will not touch the first conductor group 100 when stranding the second conductor group 200. This achieves automatic stranding for situations with small gaps between conductors, resulting in higher stranding efficiency, reduced labor intensity for operators, and more stable and reliable product quality.

[0056] It should be noted that the reversing drive component 21 in this embodiment includes, but is not limited to, cylinder action, and can also be achieved in other ways, such as through a multi-axis manipulator, linkage, or other mechanical structures. This embodiment does not limit this.

[0057] Optionally, please see Figure 3 and Figure 4 The redirecting slot 221 is an inverted trapezoidal slot, which makes the slot opening larger, facilitating the collection of at least two conductors from the first conductor group 100. Furthermore, the redirecting slot 221 is designed to converge, preventing the at least two conductors from splitting apart or becoming too far apart, thus facilitating the stranding of the inclined stranding mechanism 3. It should be noted that the bottom of the redirecting slot 221 is flat, which facilitates the support of the conductors.

[0058] Please continue reading Figure 4 The redirection block 22 includes a block body 222 and two supports 223 disposed opposite to each other on the block body 222. The two supports 223 cooperate with the block body 222 to form a redirection groove 221, and the two supports 223 have different heights, that is, one support 223 is higher than the other support 223. This allows the higher support 223 to be positioned in the gap between the two conductors when the direction of the first conductor group 100 is changed. When it is found that the distance between the support 223 and one of the conductors is too small, the position of the redirection block 22 can be adjusted in time to prevent the other support 223 from hitting the conductor that does not need to be redirected, thus ensuring the reliability of the conductor redirection mechanism 2. Figure 8 The state of the first conductor group 100 after reversal is shown. Figure 9 This is a schematic diagram showing the first conductor group 100 and the second conductor group 200 after they have been twisted together and the first conductor group 100 has been reset.

[0059] In some alternative embodiments, please continue to refer to Figure 1The stranding equipment also includes a conductor limiting mechanism 5, which limits the movement of the first conductor group 100 to prevent damage caused by excessive conductor movement. In this embodiment, as... Figure 5 As shown, the conductor limiting mechanism 5 includes a limiting drive member 51 and a limiting block 52 that is driven by the limiting drive member 51 to move in the Z direction. Figure 6 As shown, the limiting block 52 has a first limiting groove 521 arranged opposite to the redirecting groove 221 in the Z direction. The first limiting groove 521 is used to limit the conductor after bending, so that the bending angle of the conductor meets the requirements, which facilitates the stranding action of the tilting stranding mechanism 3. The first limiting groove 521 and the redirecting groove 221 are arranged opposite to each other, so that the first limiting groove 521 and the redirecting groove 221 can cooperate with each other to gather the conductor and reduce the possibility of the conductor breaking apart. The limiting drive component 51 includes, but is not limited to, cylinders, linear motors, etc., which are not limited in this embodiment.

[0060] Further optional, such as Figure 5 and Figure 6 As shown, the first limiting groove 521 is a V-shaped groove, and the opening of the first limiting groove 521 is larger than the size of the redirecting block 22, so that at least part of the redirecting block 22 can be placed in the V-shaped groove. This further reduces the conductor accommodating space formed by the groove wall of the V-shaped groove and the groove wall of the redirecting groove 221, thereby facilitating the gathering and arrangement of the conductors and making it easier to bend the first conductor group 100 to the required angle. Please continue to see Figure 6 The bottom of the V-groove has an inclined guide surface 522. The inclination angle of the guide surface 522 is equal to the bending angle of at least two conductors of the first conductor group 100. This allows the guide surface 522 to support the bent conductor, helping the conductor maintain its bent shape and facilitating the clamping of the conductor by the stranding claws of the inclined stranding mechanism 3. It should be noted that the guide surface 522 is the side surface of the block formed at the bottom of the V-groove.

[0061] Optionally, such as Figure 2 , Figure 5 and Figure 7As shown, the stranding device also includes a reset mechanism 6, which is used to reset the first conductor group 100 after bending, so that at least two conductors of the first conductor group 100 extend again along the X direction, facilitating subsequent processing steps of the connector 300. The reset mechanism 6 includes a fixed block 61 connected to the output end of the limit drive member 51, a wire pressing assembly 62 slidably connected to the fixed block 61, and an elastic member 63 disposed between the fixed block 61 and the wire pressing assembly 62. The limit drive member 51 can drive the fixed block 61 to move in the Z direction, thereby driving the wire pressing assembly 62 to move in the Z direction. Furthermore, the wire pressing assembly 62 can push the stranded first conductor group 100 to bend under the drive of the elastic member 63, so that the first conductor group 100 is reset. By setting the reset mechanism 6, the automatic reset of the first conductor group 100 is realized, which has a high reset efficiency. It also realizes the reuse of the limit drive member 51 and improves the utilization rate of the limit drive member 51.

[0062] Further optional, such as Figure 5 and Figure 7 As shown, the wire pressing assembly 62 includes a Z-axis slider 621 and a wire pressing bar 622. The fixing block 61 has a sliding hole and a second limiting groove 611 communicating with the sliding hole. One end of the Z-axis slider 621 slides in the sliding hole, and one end of the Z-axis slider 621 has a limiting structure 623 that slides in the second limiting groove 611. The elastic member 63 is located in the sliding hole and abuts against one end of the Z-axis slider 621 and the inner wall of the fixing block 61. The wire pressing bar 622 is located at the other end of the Z-axis slider 621 and is used to push the first conductor group 100 to move so that the bent first conductor group 100 is reset. The second limiting groove 611 is used to limit the lower limit of the movement of the limiting structure 623, thereby limiting the Z-axis slider 621 and the pressure bar 622 in the Z-axis. This ensures that the distance the Z-axis slider 621 drives the pressure bar 622 to push the end of the first conductor group 100 in the Z-axis is approximately equal to the distance the first conductor group 100 needs to move to reset in the Z-axis, thus ensuring that the first conductor group 100 can be reset smoothly, and that the reset first conductor group 100 can extend exactly along the X-axis. It should be noted that the first conductor group 100 is reset after at least two conductors of the first conductor group 100 are twisted together.

[0063] Optionally, the conductor carrier 1 can slide along the X-direction, and during the sliding process, the conductor carrier 1 can drive the stranded first conductor group 100 past the pressure bar 622, so that the first conductor group 100 is reset under the pressure of the pressure bar 622. Specifically, the conductor carrier 1 has an original position and a stranded position in the X-direction. When the conductor carrier 1 is in the stranded position, the limiting drive member 51 drives the limiting block 52 to move closer to the conductor, and at the same time, the pressure assembly 62 also moves closer to the conductor until it contacts the top surface of the conductor carrier 1. The conductor reversing mechanism 2 pushes the first conductor group 100 to reverse direction, the tilting stranding mechanism 3 strands at least two conductors of the first conductor group 100, and the horizontal stranding mechanism 4 strands at least two conductors of the second conductor group 200. During the movement of conductor carrier 1 from the stranded position back to its original position, the wire pressing assembly 62 moves relative to conductor carrier 1 until it detaches from conductor carrier 1. After detaching from conductor carrier 1, elastic member 63 pushes out of pressing bar 622 until limiting structure 623 contacts the bottom wall of second limiting groove 611. As conductor carrier 1 continues to move, pressing bar 622 presses the end of first conductor group 100 in the Z direction until first conductor group 100 is reset. It should be noted that the elastic force of elastic member 63 is greater than the deformation force of first conductor group 100 to smoothly press first conductor group 100.

[0064] In some alternative embodiments, such as Figure 7 As shown, the wire pressing assembly 62 also includes a roller 624, which is mounted on the other end of the Z-axis slider 621. The roller 624 can roll on the top surface of the conductor carrier 1 to reduce the frictional force between the wire pressing assembly 62 and the conductor carrier 1. In some embodiments, the roller 624 is coaxial with the wire pressing bar 622, so that the rolling of the roller 624 is not disturbed by the wire pressing bar 622.

[0065] Optionally, the stranding device in this embodiment further includes a support frame. The conductor carrier 1 is slidably mounted on the support frame along the X direction. The redirecting drive 21, the tilting stranding mechanism 3, the horizontal stranding mechanism 4, and the limiting drive 51 are respectively fixed on the support frame. The stranding device also includes a control system. The control system can be connected to the redirecting drive 21, the tilting stranding mechanism 3, the horizontal stranding mechanism 4, and the limiting drive 51 of the stranding device, and can control the start and stop of these components to smoothly achieve stranding of the product.

[0066] It should be noted that the stranding device in this embodiment can be a multi-station structure, capable of stranding multiple products simultaneously. For example, this embodiment shows a case including two stations, where two redirecting blocks 22 are driven by the same redirecting drive 21, two limiting blocks 52 are driven by the same limiting drive 51, and two wire pressing bars 622 are connected to a Z-axis sliding block and driven to move by a limiting drive 51.

[0067] Example 2

[0068] This embodiment provides a stranding method, applied to the stranding device of Embodiment 1, such as... Figure 10 As shown, it includes the following steps:

[0069] S1. Fix multiple conductors to conductor carrier 1, wherein at least two conductors of the first conductor group 100 and at least two conductors of the second conductor group 200 have residual inner sheaths at their ends.

[0070] In step S1, multiple conductors are fixed by fixing the connector 300 to the conductor carrier 1. The extended direction of the fixed conductors is parallel to the X-direction. Figure 8 As shown, at least two conductors of the first conductor group 100 and at least two conductors of the second conductor group 200 have residual inner sheaths. By covering the conductors with residual inner sheaths, the probability of the conductor wires breaking apart is reduced, thereby avoiding the situation where the wires of different types of conductors are twisted together.

[0071] S2. Control the reversing drive 21 to drive the reversing block 22 to move in the Z direction, so that the first conductor group 100 is located in the reversing groove 221, and push the first conductor group 100 to bend through the reversing groove 221, so that at least two conductors of the first conductor group 100 are bent at an angle to at least two conductors of the second conductor group 200.

[0072] It should be noted that the conductor not only has a remaining inner sheath, but also an exposed portion. In this embodiment, the redirection block 22 contacts the exposed portion of the conductor to prevent interference with subsequent stranding.

[0073] S3. Control the tilting stranding mechanism 3 to strand at least two conductors of the first conductor group 100. During the stranding process of the first conductor group 100, control the tilting stranding mechanism 3 to gradually retract, and remove the remaining inner sheath on the conductors of the first conductor group 100 during the retraction.

[0074] like Figure 8 As shown, due to the change in direction of the first conductor group 100 and its angle with the second conductor group 200, a large operating space exists around the first conductor group 100. Therefore, when the stranding claws of the tilting stranding mechanism 3 grip at least two conductors of the first conductor group 100, they will not touch the second conductor group 200. During the stranding process, the tilting stranding mechanism 3 can gradually retract and remove the remaining conductor from the conductor to strand the exposed portion of the conductor.

[0075] S4. Control the horizontal stranding mechanism 4 to strand at least two conductors of the second conductor group 200. During the stranding process of the second conductor group 200, control the horizontal stranding mechanism 4 to gradually retract, and remove the remaining inner sheath on the conductors of the second conductor group 200 during the retraction.

[0076] like Figure 8 As shown, due to the change in direction of the first conductor group 100 and its angle with the second conductor group 200, a large operating space exists around the second conductor group 200. Therefore, when the stranding claws of the horizontal stranding mechanism 4 grip at least two conductors of the second conductor group 200, they will not touch the first conductor group 100. During the stranding process, the horizontal stranding mechanism 4 can gradually retract and remove the remaining conductor from the conductor to strand the exposed portion of the conductor.

[0077] It should be noted that the order of steps S3 and S4 can be adjusted, such as executing step S4 first and then step S3. This embodiment does not limit this.

[0078] The stranding method provided in this embodiment includes a conductor reversing mechanism 2 comprising a reversing drive 21 and a reversing block 22. The reversing block 22 can bend at least two conductors of the first conductor group 100 under the drive of the reversing drive 21, thereby changing the extension of the at least two conductors along the X direction to an extension direction intersecting both the X and Z directions. This adjusts the extension direction of the conductors in the first conductor group 100, thereby providing a larger operating space around both the first conductor group 100 and the second conductor group 200. This ensures that the tilting stranding mechanism 3 will not touch the second conductor group 200 when stranding the first conductor group 100, and the horizontal stranding mechanism 4 will not touch the first conductor group 100 when stranding the second conductor group 200. This achieves automatic stranding for situations with small gaps between conductors, resulting in higher stranding efficiency, reduced labor intensity for operators, and more stable and reliable product quality.

[0079] Optionally, when the stranding device includes a conductor limiting mechanism 5 and a reset mechanism 6, the stranding method further includes the following steps before step S2:

[0080] The limit drive 51 drives the limit block 52 to move a preset distance in the Z direction, and pushes the roller 624 to contact the top surface of the conductor carrier 1 through the fixing block 61 and the Z-direction slider 621 of the reset mechanism 6. The elastic member 63 of the reset mechanism 6 is squeezed into a contracted state.

[0081] Following step S4, the stranding method further includes the following steps:

[0082] The conductor carrier 1 moves along the X direction from the stranded wire position. During the movement, the roller 624 rolls on the conductor carrier 1. After the roller 624 rolls out of the conductor carrier 1, the elastic element 63 pushes the Z-direction sliding block to move closer to the first conductor group 100, so as to push the first conductor group 100 to move through the wire pressing bar 622 until the limiting structure 623 of the wire pressing assembly 62 contacts the second limiting groove 611, so as to reset the first conductor group 100.

[0083] This embodiment provides a more detailed stranding process. Specifically: First, the connector 300 is fixed to the conductor carrier 1. At this time, the conductor carrier 1 is in its original position, and multiple conductors extend along the X direction. Then, the conductor carrier 1 is moved from its original position to the stranding position. Next, the limiting drive 51 is activated to drive the wire pressing assembly 62 and the limiting block 52 to descend. After descending a preset distance, it stops. At this time, the first limiting groove 521 of the limiting block 52 is located above the first conductor group 100, the roller 624 contacts the top surface of the conductor carrier 1, the Z-axis slider 621 moves upward, and the elastic member 63 is compressed. Then, the redirecting drive 21 is activated to drive the redirecting block 22 to move upward, so that the first conductor group 100 is located in the redirecting groove 221, and the first conductor group 100 is continued to be pushed so that at least two conductors of the first conductor group 100 are bent. Figure 8 The state is shown. Then, the horizontal stranding mechanism 4 is moved forward to strand at least two conductors of the second conductor group 200, removing any remaining material from the conductors during stranding. Next, the inclined stranding mechanism 3 is moved forward to strand at least two conductors of the first conductor group 100. It should be noted that both the forward movement of the horizontal stranding mechanism 4 and the forward movement of the inclined stranding mechanism 3 can be controlled by moving the stranding claw forward, and the stranding claw is used to remove any remaining material; this embodiment does not limit this. After this, the conductor carrier 1 is moved back to its initial position. During the retraction, the roller 624 rolls on the top surface of the conductor carrier 1. After rolling away from the carrier, under the action of the elastic member 63, the pressure bar 622 presses down on the first conductor group 100. Furthermore, the pressing down of the pressure bar 622 occurs simultaneously with the retraction of the conductor carrier 1, thereby completing the reset of the first conductor group 100. Finally, the reversing block 22 is reset by the reversing drive 21, and the pressure wire assembly 62 and the limit block 52 are reset by the limit drive 51.
