For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Fig. 1 and 2 illustrate a flying lead mount 10 in some embodiments of the utility model, the flying lead mount 10 being used to carry a flying lead into water to a predetermined underwater location. The flying lead frame 10 includes a main body 1, a first side 11 and a second side 12 opposite to the first side 11 are provided on the main body 1, a first winding portion 21 and a third winding portion 23 are provided on the first side 11, and a second winding portion 22 and a fourth winding portion 24 are provided on the second side 12.

The first winding part 21 is used for winding a first part 31 of the first flying lead 3, and the second winding part 22 is used for winding a second part 32 of the first flying lead 3, so that the connection part of the first part 31 and the second part 32 of the first flying lead 3 is arranged between the first side 11 and the second side 12;

the third winding 23 is intended to wind the first portion 41 of the second flying wire 4 and the fourth winding 24 is intended to wind the second portion of the second flying wire 4, so that the connection of the first portion 41 and the second portion 42 of the second flying wire 4 is placed between the first side 11 and the second side 12.

It can be understood that the positions of the first winding and connecting portion 21, the second winding and connecting portion 22, the third winding and connecting portion 23, and the fourth winding and connecting portion 24 can be flexibly set according to different use scenes, for example, the first winding and connecting portion 21, the second winding and connecting portion 22, the third winding and connecting portion 23, and the fourth winding and connecting portion 24 can be set to be axially symmetrically distributed with the central axis of the main body 1, so that the flying lead frame 10 can keep stability during hoisting into water, and the flying lead frame 10 can be prevented from being hoisted and inclined.

It will also be appreciated that the first side 11 and the second side 12 may be left and right sides or upper and lower sides on the body; specifically, the first flying wire 3 and the second flying wire 4 on the main body 1 falling into the predetermined position can be smoothly taken down, and the first flying wire 3 and the second flying wire 4 are preferably prevented from being stuck in the installation and laying process. The first flying lead and the second flying lead each have two parts, a first part and a second part, and the winding positions of the respective first part and the second part are different.

As shown in fig. 1, 2 and 3, the main body 1 may be provided with an empty space 13 in some embodiments, at least one side of the empty space 13 is open to communicate with the outside, and the empty space 13 is used for accommodating a connection portion of the first part 31 and the second part 32 of the first flying lead 3 and a connection portion of the first part 41 and the second part 42 of the second flying lead 4.

As can be appreciated, the clearance space 13 is used to provide a free space for the connection of the first part 31 and the second part 32 of the first flying lead 3 to disengage from the main body 1, and is also used to provide a free space for the connection of the first part 41 and the second part 42 of the second flying lead 4 to disengage from the main body 1; further, the clearance 13 may be an opening, a groove, or a hole directly communicating with the outside.

It can be understood that, when the first flying lead 3 is unwound, the connecting portion of the first part and the second part on the first flying lead 3 can directly pass through the vacancy-avoiding portion 13 and move to the outside of the flying lead frame 10, so that the first flying lead 3 completely breaks away from the flying lead frame 10 and falls onto the seabed; similarly, the clearance 13 can also make the second flying lead 4 separate from the flying lead frame 10 in the unwinding process of the second flying lead 4; the trouble that underwater equipment such as an ROV (remote operated vehicle) is connected with the flying line frame 10 is avoided, and the installation efficiency of the flying line is further improved.

Preferably, as shown in fig. 1 and 3, the clearance bit 13 may be disposed at the bottom of the flying stand 10 in some embodiments. It can be understood that, when the first flying lead 3 or the second flying lead 4 is unwound and installed, the first flying lead 3 or the second flying lead 4 will sink further under the action of its own weight, so that the respective connecting portions of the first flying lead 3 and the second flying lead 4 automatically separate from the flying lead frame 10 and fall onto the seabed, thereby further improving the installation efficiency of the underwater flying lead.

As shown in fig. 4a, 4b, 4c and 4d, the first winding part 21, the second winding part 22, the third winding part 23 and the fourth winding part 24 are disposed on the main body 1 in at least the following embodiments:

in the first embodiment, as shown in fig. 4a, the first winding part 21 and the second winding part 22 are adjacent to each other and are located near the center of the main body 1; the third winding portion 23 is provided on the outer side of the first winding portion 21 away from the center of the main body 1, and the fourth winding portion 24 is provided on the outer side of the second winding portion 22.

It can be understood that, in this embodiment, the first part 31 and the second part 32 of the first flying lead 3 are both located near the center of the flying lead frame 10 after being wound, and the first part 41 and the second part 42 of the second flying lead 4 are both located far from the center of the flying lead frame 10, so that during the flying lead installation, the second flying lead 4 located outside the flying lead frame 10 needs to be unwound and laid first to avoid the second flying lead 4 from being entangled with the first flying lead 3 wound on the flying lead frame 10 during the unwinding process, and ensure that the second flying lead 4 can be smoothly separated. Specifically, the connection portion of the first flying lead 3 should be located between the connection portion of the second flying lead 4 and the main body 1, so that after the first portion 41 and the second portion 42 of the second flying lead 4 are unwound, the connection portion of the second flying lead 4 can be directly separated from the flying lead frame 10 without interference of the connection portion of the first flying lead 3, and the laying and installation of the second flying lead 4 are completed.

In the second embodiment, as shown in fig. 4b, the first winding part 21 and the third winding part 23 are adjacent to each other and are located near the center of the main body 1; the second winding portion 22 is disposed on an outer side of the third winding portion 23 away from the center of the main body 1, and the fourth winding portion 24 is disposed on an outer side of the first winding portion 21 away from the center of the main body 1.

It will be appreciated that in this embodiment, one of the first and second portions of the first fly line 3 is wound around the fly stand 10 near the center thereof, the other is wound around the fly stand 10 near the outer side thereof, and so are the two portions of the second fly line 4; therefore, in this embodiment, the flying leads located outside the flying lead frame 10 need to be unwound each time, that is, a part of each of the two flying leads is laid and installed, so that the two flying leads are prevented from being entangled with each other during the unwinding and laying process. Specifically, the connecting portion of the flying line which needs to be completely loosened later should be located between the connecting portion of another flying line and the main body 1, so that the connecting portion of the flying line which is completely loosened first can smoothly separate from the flying line frame 10, and the purpose of laying and installing the second flying line 4 is achieved.

In the third embodiment, as shown in fig. 4c, the first winding portion 21 and the fourth winding portion 24 are disposed on the same side of the body, the second winding portion 22 and the third winding portion 23 are disposed on the other side of the body, the first winding portion 21 and the third winding portion 23 are adjacent, and the second winding portion 22 and the fourth winding portion 24 are adjacent.

It is to be understood that, in this embodiment, a space is provided between the first winding portion 21 and the fourth winding portion 24, and a space is also provided between the second winding portion 22 and the third winding portion 23; in this way, the connection portion on the first flying lead 3 and the connection portion on the second flying lead 4 intersect between the first side 11 and the second side 12; therefore, in the process of unwinding and laying the flying leads, the flying leads with the connecting parts far away from the main body 1 need to be unwound first, so that the connecting parts of the flying leads are smoothly separated, and the laying and installation of the other flying leads are prevented from being hindered.

In the fourth embodiment, as shown in fig. 4d, the first winding portion 21 and the third winding portion 23 are disposed on the same side of the body, the second winding portion 22 and the fourth winding portion 24 are disposed on the other side of the body, the first winding portion 21 and the second winding portion 22 are adjacent, and the third winding portion 23 and the fourth winding portion 24 are adjacent.

It is to be understood that, in this embodiment, a space is provided between the first winding portion 21 and the third winding portion 23, and a space is also provided between the second winding portion 22 and the fourth winding portion 24; in this way, the connection parts of the first flying wire 3 and the second flying wire 4 will not cross between the first side 11 and the second side 12 of the main body 1, and the connection parts of the first flying wire and the second flying wire will not be entangled with each other in the process of unwinding and laying the flying wires, so that the worker can flexibly adjust the laying and installation sequence of the two flying wires.

In the above embodiments, two flying leads can be simultaneously wound on the same flying lead frame 10, so that a single flying lead frame 10 can carry the two flying leads and enter water simultaneously, and the flying lead installation efficiency is improved. Further, the first winding portion 21, the second winding portion 22, the third winding portion 23, and the fourth winding portion 24 may have the same or different structures, and the flying wire may be wound along a predetermined trajectory.

Further, as shown in fig. 1 and 2, the main body 1 in some embodiments has two spaced-apart bobbins 5 protruding from the first side 11 and the second side 12, respectively, for the first flying lead 3 and the second flying lead 4 to be wound in a figure-8 shape.

It can be understood that a single bobbin 5 may be composed of a plurality of winding rollers 51, and when in use, flying wires are threaded through or around each winding roller 51 according to a predetermined track; the single winding frame 5 can also be arranged into a column-like shape, and when the flying lead winding machine is used, the flying leads are wound on the outer sides of the two column-like bodies according to a preset track, and the first flying lead 3 and the second flying lead 4 can also be wound in an 8 shape. Of course, the first flying wire 3 and the second flying wire 4 can also be wound in a circular shape or a ring shape, as long as the flying wires are not interfered and blocked by the flying wires and the other flying wire in the laying process when being taken down.

Furthermore, as shown in fig. 4a, in the first embodiment in which the first winding part 21 and the third winding part 23 are located on the same side and are connected to each other, the portions of the two winding frames 5 located on the first side 11, which are close to the main body 1, together constitute the first winding part 21, and the portions of the two winding frames, which are far from the main body 1, together constitute the third winding part 23; and the parts of the two bobbins 5 on the second side 12, which are close to the main body 1, form a second winding part 22, and the parts of the two bobbins which are far from the main body 1 form a fourth winding part 24.

Furthermore, as shown in fig. 4b, for the second embodiment in which the first winding part 21 and the fourth winding part 24 are located on the same side and connected to each other, the portions of the two winding frames 5 located on the first side 11, which are close to the center of the main body 1, jointly form the first winding part 21, and the portions of the two winding frames, which are far from the center of the main body 1, jointly form the fourth winding part 24; and the parts of the two bobbins 5 on the second side 12, which are close to the center of the main body 1, form a third winding part 23, and the parts of the two bobbins which are far from the center of the main body 1 form a second winding part 22.

Further, as shown in fig. 1 and 2, each bobbin 5 of the main body 1 may include two parts, and the two parts of a single bobbin 5 may achieve the purpose of guiding the flying leads to be wound in an 8-shape. It will be appreciated that both parts within a single bobbin 5 may be comprised of several winding rollers 51, or other structures such as cylinder-like structures, on which flyer wire may be wound.

Furthermore, as shown in fig. 2, 4c and 4d, the third embodiment in which the first winding portion 21 and the fourth winding portion 24 are located on the same side and a space is provided therebetween, and the fourth embodiment in which the first winding portion 21 and the third winding portion 23 are located on the same side and a space is provided therebetween are both provided. Two parts of a single winding frame 5 can form a single winding part, namely, the single winding frame 5 can complete 8-shaped, annular or circular winding of the first part or the second part of the single flying wire.

As shown in fig. 1, the single bobbin 5 may include a plurality of winding rollers 51 disposed on the main body 1 in some embodiments, and the winding rollers 51 are sequentially disposed so that flying threads can be wound on the winding rollers 51 along a predetermined trajectory.

It will be appreciated that, in use, the fly thread can be wound and fixed on the fly stand 10 in a predetermined path by passing the fly thread through or around the respective winding rollers 51 in a predetermined path. In order to avoid the damage of the flying leads due to overlarge bending degree in the winding process, the arrangement position of each winding roller 51 is matched with the maximum bending degree of the flying leads, and the actual bending degree of the flying leads wound on each flying lead roller is ensured to be always larger than or equal to the maximum bending degree of the flying leads.

Optionally, the single bobbin 5 may be configured in a column-like shape in other embodiments, and when in use, the flying leads are wound on the outer sides of the two column-like bodies according to a predetermined track, and the first flying lead 3 and the second flying lead 4 may also be wound in an 8 shape. Of course, the first flying wire 3 and the second flying wire 4 can also be wound in a circular shape or a ring shape, as long as the taken-off flying wires are not interfered and blocked by the flying wires and the other flying wire in the installation and laying process.

Further, as shown in fig. 1 and 3, each bobbin 5 may further include a winding plate 52 disposed above each winding roller 51 in some embodiments, and the winding plate 52 is upwardly curved to protrude to form a winding arc 521, and the winding arc 521 is used to guide the flying wire to be wound along a predetermined arc. That is, in each bobbin 5, at least one winding plate 52 is used in conjunction with each winding roller 51 for winding flying wire.

It can be understood that the profile and the bending degree of the winding arc surface 521 are flexibly adjusted according to the technical specification of the flying lead, for example, in the actual winding process of the flying lead, it should be noted that the maximum bending degrees that the flying leads with different specifications can bear are different, and if the bending degree of the flying lead is too large, the bending part is easily damaged by stress concentration; therefore, the curvature of the surface profile of the winding arc 521 should be greater than or equal to the maximum curvature of the flying wire.

It can also be understood that after the fly line is wound on the fly frame 10, each loop of fly line will be folded inwards from two sides under the action of its own weight, resulting in further bending of the top portion of each loop of fly line due to stress, and the fly line will be damaged if the bending degree is too large. In this regard, the winding plate 52 in each bobbin 5 may be disposed above each winding roller 51, which acts to limit the degree of bending of the top of each loop of flyer wire, and ensure that the degree of bending of the flyer wire at the top is maintained within a standard range when the flyer wire is folded inward under its own weight;

secondly, only the winding plate 52 is arranged at the top of the flying lead frame to lift and limit the flying lead, so that the overall weight of the flying lead frame 10 can be reduced as much as possible under the condition of ensuring the bending degree of the flying lead, and the flying lead frame 10 is more favorable for water entering and hoisting.

As shown in fig. 3, the main body 1 may include a chassis 14, two uprights 15 disposed on the chassis 14, and a cross member 16 connected to the two uprights 15, respectively; a spacer 17 is provided between the cross beam 16 and the chassis 14, and a first winding portion 21, a second winding portion 22, a third winding portion 23, and a fourth winding portion 24 are provided on the spacer 17, respectively.

It will be appreciated that the chassis 14 acts as a support for the uprights 15, ensuring that the uprights 15 remain stable after entry into the water. The upright post 15 and the cross beam 16 fix the partition 17 together from all directions, so that the partition 17 is prevented from being bent or deformed due to winding and hanging of overlong and overweight flying leads, and the durability of the flying lead frame 10 is improved. The isolation piece 17 plays a role in isolating the flying line, prevents the flying line from being entangled and knotted, and ensures the underwater installation and laying success rate of the flying line to a certain extent.

Further, as shown in fig. 3, the flying lead frame 10 may be provided with several fixing locations 18 in some embodiments, each for fixing a joint on the flying lead. It can be understood that, in the use process, the joints on the flying line are correspondingly fixed in the fixing positions 18, so that the joints can be prevented from swinging to be knotted or loosened, and the like, and the normal installation and laying of the flying line are influenced.

It will also be understood that the number of fixing locations and flying lead joints may be set equal, and that some fixing locations are disposed on the first side 11 and the remaining fixing locations are disposed on the second side 12; thus, the mutual winding of the joints of the flying leads can be further avoided.

Specifically, as shown in fig. 3, the flying lead frame 10 may be provided with a plurality of insertion holes 19, and the hole walls of the insertion holes respectively enclose the fixing positions. It can be understood that the fixation can be completed only by correspondingly inserting each joint on the flying lead into each insertion hole 19, and the fixing mode of the joints is simple and convenient to operate.

Further, as shown in fig. 3, the spacer 17 may include a plurality of connecting members 171 in some embodiments, wherein the connecting members are connected in a predetermined arrangement, and the connecting members together define a plurality of lightening holes.

It can be understood that the connecting member 171 can be formed by connecting rigid members such as H-shaped steel, i-shaped steel or channel steel, so that the rigidity of the whole flying lead frame 10 can be ensured, the whole weight of the flying lead frame 10 can be reduced as much as possible, and the durability and the hoisting simplicity of the flying lead frame 10 can be improved.

Further, as shown in fig. 3, the chassis 14 may include two bottom plates 141 having a plurality of water holes 142 formed therein, the two bottom plates are spaced apart from each other, and even have frames 143 along the edges of the bottom plates, the pillars 15 are connected to the frames in a one-to-one correspondence, and the spacers 17 are connected to the two frames, respectively.

Understandably, the contact area between the flying line frame 10 and the seabed can be increased by the two bottom plates, the stability and the smoothness of the flying line frame 10 after entering water are improved, and the installation success rate of the flying line is ensured. The water holes 142 are formed, so that when the flying lead frame 10 enters water, liquid can quickly overflow through the side frame, and the flying lead frame 10 can smoothly and quickly enter the water.

As shown in fig. 3, the top of the beam 16 may in some embodiments be provided with an operating handle 161 adapted to the underwater equipment. It can be understood that the arrangement of the operating handle enables underwater equipment such as an ROV and the like to adjust the specific placement position of the flying lead frame 10 through the operating handle 161, and improves the convenience of use of the product.

S6, the third connector of the first portion 41 of the second flying lead 4 is fixed to the third fixing position on the first side 11 of the flying lead 10, and the fourth connector of the second portion of the second flying lead 4 is fixed to the fourth fixing position on the second side 12 of the flying lead 10.

It can be understood that after the winding of the first flying lead 3 and the second flying lead 4 is completed, the closer the portion of the first portion 31 of the first flying lead 3 is to the first joint, the farther the distance from the main body 1 is, that is, the first portion can be wound toward the extending direction of the first joint in the direction gradually away from the main body 1 during the winding process; so, take off first joint and the in-process of seeing off towards the direction of keeping away from main part 1, the first part 31 of first fly line 3 will be followed first winding portion 21 and come loose gradually, avoids first part to appear entangling and knoing and lead to the fly line installation failure at the in-process of unreeling with other parts, has improved fly line installation success rate, has removed the loaded down with trivial details of repeatedly adjusting the fly line position from, has guaranteed the installation effectiveness of fly line.

Likewise, the closer the portion of the second part to the second joint is to the body 1; the second flying lead 4 is wound in a similar way to the first flying lead 3, so that the parts on the second flying lead 4 are prevented from overlapping each other.

s7, the flying lead frame 10 with the flying leads wound thereon is placed at a predetermined position on a predetermined flying lead laying trajectory.

The method can be understood that the preset flying line laying track is the preset laying track of the flying line, and the track is flexibly adjusted according to the underwater seabed environment, the flying line length, the construction difficulty and the like. The preset placement position of the flying line frame 10 also needs to be determined according to conditions such as seabed environment and the like, the stability of the flying line frame 10 in the construction process is ensured, the phenomenon that the flying line frame 10 inclines or even collapses in the flying line traction process is prevented, and the success rate of flying line installation is ensured. In particular, the creel stand 10 may be hoisted into the water and then guided against the predetermined placement with the aid of an ROV.

S8, removing and attaching the first connector to the predetermined plugging position, and removing and attaching the second connector to the predetermined plugging position, so as to separate the connection part of the first part and the second part on the first flying lead 3 from the flying lead frame 10.

It will be appreciated that, when the first flying lead is removed and pulled towards the predetermined plugging position on the subsea system, the first portion 31 of the first flying lead 3 will gradually come loose from the first winding 21, and after plugging the first flying lead to the predetermined plugging position, the first portion will also come completely loose from the first winding 21, i.e. the first portion 31 of the first flying lead 3 will be detached from the flying lead frame 10; subsequently, after the second connector is pulled and inserted into the predetermined insertion position of the underwater system, the second part 32 of the first flying lead 3 will also completely fall off from the flying lead frame 10, so that the connection part of the first part and the second part on the first flying lead 3 will be separated from the flying lead frame 10; the installation of the first flying lead 3 is completed.

S9, removing and attaching the third connector to the predetermined plugging position, and removing and attaching the fourth connector to the predetermined plugging position, so as to separate the connection part of the first part and the second part on the second flying lead 4 from the flying lead frame 10.

It can be understood that, when the third joint is removed and installed in the predetermined plugging position in a pulling way, and the fourth joint is removed and installed in the predetermined plugging position in a pulling way, the connection part of the first part and the second part on the second flying lead 4 is also separated from the flying lead frame 10, so that the second flying lead 4 is completely separated from the flying lead frame 10, and the installation of the second flying lead 4 is completed. Specifically, the ROV may be used to remove each of the connectors and install them into a predetermined plugging location.

Further, the execution sequence of the steps S8 and S9 can be flexibly changed, but it should be noted that when the first fly thread 3 is unwound first, the connecting portion between the first part and the second part of the first fly thread 3 needs to be prevented from being blocked or blocked by the second fly thread 4 which is not unwound yet and being unable to smoothly separate from the fly stand 10. Accordingly, when the second flying lead 4 is released first, it is necessary to avoid the second flying lead 4 being stuck by the first flying lead 3 and being unable to smoothly separate from the flying lead frame 10. Specifically, in order to avoid the interference between the connecting portions of the first and second portions of the first flying lead 3 and the connecting portions of the first and second portions of the second flying lead 4, the connecting portions may be directly separated from the flying leads 10 and unwound.

Further, before performing steps S8 and S9, steps of: the sundry garbage and the like on the predetermined flying yarn laying track of the first flying yarn 3 and the second flying yarn 4 are cleaned. It will be appreciated that the cleaning step may be performed using underwater equipment such as an ROV.

Understandably, when the first flying lead 3 is unwound, the connecting part of the first part and the second part on the first flying lead 3 can directly pass through the vacancy avoiding position 13 and move to the outside of the flying lead frame 10, so that the first flying lead 3 is completely separated from the flying lead frame 10; similarly, the clearance 13 also enables the second flying lead 4 to be separated from the flying lead frame 10 in the unwinding process of the second flying lead 4. The space-avoiding portion 13 may be an opening, a groove or a hole formed in the flying lead frame 10.

Preferably, the clearance 13 is disposed at the bottom of the flying lead frame 10. It can be understood that, when the first flying lead 3 or the second flying lead 4 is unwound and installed, the first flying lead 3 or the second flying lead 4 further sinks under the action of self weight, so that the respective connecting parts of the first flying lead 3 and the second flying lead 4 are automatically separated from the flying lead frame 10, and the installation efficiency of the underwater flying lead is further improved.

As shown in fig. 5, the ratio of the length of the first section 31 to the length of the second section 32 on the first flying lead 3 is R1, the distance from the predetermined placement position of the flying lead frame 10 to the predetermined plugging position of the first connector is D1, and the distance from the predetermined placement position of the flying lead frame 10 to the predetermined plugging position of the second connector is D2; wherein, R1 is D1/D2.

It can be understood that, due to the different complexity of the sea floor, there may be some locations on the predetermined flying line laying track which are not suitable for placing the flying line frame 10, and when D1 ≠ D2, the length of the first part of the first flying line 3 wound around the first winding part 21 and the length of the second part wound around the second winding part 22 are adaptively adjusted, so that R1 ≠ D1/D2. In this way, when the first joint is connected to the predetermined position in a pulling manner, the first part of the first flying lead 3 is just completely released from the first winding part 21, and when the second joint is connected to the predetermined position in a pulling manner, the second part of the first flying lead is also just completely released from the second winding part 22, so that the fixation of the first joint and the second joint can be completed synchronously with the separation of the first flying lead 3 and the flying lead frame 10, and the installation efficiency of the flying lead is improved.

It will also be appreciated that the ratio of the length of the first section 41 to the length of the second section 42 of the second flying lead 4 is R2, the distance from the predetermined placement position of the flying lead frame 10 to the predetermined plugging position of the third connector is D3, and the distance from the predetermined placement position of the flying lead frame 10 to the predetermined plugging position of the fourth connector is D4; wherein, R2 is D3/D4. The fixation of the third joint and the fourth joint and the separation of the second flying lead 4 and the flying lead frame 10 can be synchronously completed, and the installation efficiency of the flying leads is further improved.

Further, the flying lead installation method of the present invention may further include, in some embodiments, after completing installation of the first flying lead 3, the steps of:

The second portion can be placed on the second side 12 by placing the connecting portion across the partition structure, and the worker can wrap the second portion around the second side 12.

S13, the second part 32 of the first flying lead 3 is wound around the second winding part 22 for a predetermined number of turns so that the turns of the first flying lead 3 at the second winding part 22 do not overlap each other. It can be understood that, referring to the foregoing similar winding manner of the first part on the first fly line 3, the loops of fly lines wound by the second part and not overlapped with each other can also prevent the second part from being accidentally entangled and knotted in the unwinding process, thereby ensuring the installation success rate of the fly lines.

It can be understood that, in the present embodiment, first, the user can roughly measure the lengths of the first portion and the second portion that need to be reserved on the first flying lead 3 according to the underwater installation position of the flying lead frame 10, so as to roughly estimate the rough position of the connection portion between the first portion and the second portion on the first flying lead 3, and then, the step S12 can be executed to complete the placement of the connection portion to complete the flying lead length allocation of the first flying lead 3 on the first side 11 and the second side 12, and then the steps S11 and S13 are executed to complete the winding of the first flying lead 3. Next, step S11 and step S13 may be replaced with each other regardless of whether the first flying lead 3 is wound or positioned by any portion.

As shown in fig. 5, step S2 specifically includes, in some embodiments:

s21, the first part 41 of the second flying lead 4 is wound around the third winding portion 23 for a predetermined number of turns so that the turns of the second flying lead 4 do not overlap each other at the third winding portion 23. It is understood that the winding method of the first part 41 of the second flying lead 4 can refer to step S11, so that the first part 41 of the second flying lead 4 can be unwound from turn to turn during unwinding, and will not get entangled with each other, thereby ensuring the correct installation of the flying leads.

S22, placing the connecting portion of the first portion and the second portion on the second flying lead 4 between the first side 11 and the second side 12. It can be understood that when the connecting portions of the first portion and the second portion of the second flying lead 4 are arranged, the connecting portions are prevented from being entangled with the connecting portions of the first flying lead 3, so that the connecting portions of the first flying lead 3 and the second flying lead 4 are prevented from being entangled with each other in the respective unwinding installation process, the flying leads needing to be unwound cannot be smoothly separated from the flying lead frame 10 due to the blocking of the connecting portion of the other flying lead, and the installation success rate of the flying leads is further ensured.

S23, the second part of the second flying lead 4 is wound around the fourth winding portion 24 for a predetermined number of turns, and the turns of the first flying lead 3 at the fourth winding portion 24 do not overlap each other. It will be appreciated that the winding method of the second portion of the second flying lead 4 refers to step S21 to increase the installation capacity of the flying lead.

It should also be understood that, in the winding step of the second flying lead 4 in this embodiment, step S22 may be performed to position the connecting portion on the second flying lead 4, and then step S21 and step S23 may be performed. Secondly, whether the first part or the second part is wound or the positioning connection part is arranged, the steps S21 and S23 can be replaced with each other.
