Description

Technical Field

[0001] This utility model relates to an optical fiber winding device, specifically to a wire supply device for winding optical fiber rings. Background Technology

[0002] Existing fiber optic winding devices typically consist of a spindle, a follower disk, a cable laying device, and a cable supply module. The spindle is the core component of the fiber optic winding device, responsible for driving the follower disk and the cable supply module mounted on it to rotate. The follower disk acts as a bridge connecting the spindle and the cable supply module, ensuring synchronous movement between the two. The cable laying device is used to move the cable supply module and change the direction of fiber winding.

[0003] A fiber optic cable supply module typically consists of a supply wheel, a swing arm, and a tension wheel. The supply wheel is wound with optical fiber. As the winding process progresses, the fiber is released from the supply wheel, and the tension wheel adjusts the tension on the fiber before guiding it to the winding position. The swing arm is connected to the tension wheel and adjusts its position, thus regulating the fiber tension. When the supply module rotates with the rotating disk and spindle, the swing arm experiences an outward centrifugal force. As the rotational speed increases, the centrifugal force also increases, causing the swing arm to swing more easily. This swinging of the swing arm alters the fiber path, affecting the fiber tension. If the tension is too low, the fiber may loosen, affecting the winding quality; if the tension is too high, it may damage the fiber or even cause it to break. Especially at high speeds, the frequent swinging of the swing arm causes uneven tension changes in the fiber, increasing the risk of damage. Utility Model Content

[0004] The purpose of this invention is to provide a wire supply device for winding optical fiber rings. The technical problem to be solved is how to reduce the amplitude of the swing arm swing and reduce the degree of change in optical fiber tension when the wire supply module follows the rotating disk.

[0005] This utility model is achieved through the following technical solution:

[0006] A wire supply device for winding optical fiber rings is provided. The wire supply device is used to connect to a follower disk or a wire laying device. When the wire supply device is connected to the follower disk, it rotates with the follower disk. When the wire supply device is connected to the wire laying device, it moves with the wire laying device. The wire supply device includes a frame body, and the frame body is provided with a tension adjustment component and a locking component. The locking component is located next to the tension adjustment component.

[0007] The tension adjustment assembly includes a tension wheel, a swing member, a first connecting shaft, and a first driver. One end of the swing member is connected to the first connecting shaft, and the other end of the swing member is connected to the tension wheel. The first connecting shaft is connected to the output shaft of the first driver, and the first driver is used to drive the first connecting shaft to rotate.

[0008] When the wire supply device is connected with the follow-up disc, the locking assembly locks the first connecting shaft.

[0009] In order to ensure that the optical fiber has stable tension during winding, prevent the optical fiber from being damaged or the winding quality from being reduced due to excessive change of the tension, the locking assembly is introduced. When the wire supply device is connected with the follow-up disc and rotates with the follow-up disc, the locking assembly locks the first connecting shaft, which means that the first connecting shaft is fixed and its rotation is limited. Since the first connecting shaft is connected with one end of the swing piece, when the first connecting shaft is locked, the swing piece also loses the ability to swing through the first connecting shaft.

[0010] Specifically, the locking assembly fixes the first connecting shaft at a certain position by a mechanical method, so that even if the follow-up disc rotates with the wire supply device, the swing piece cannot produce large-scale swinging due to external factors. Since the swinging of the swing piece is limited, the position of the tension wheel connected with the swing piece is also relatively stable. The tension wheel is directly in contact with the optical fiber, and the stability of the tension wheel can effectively maintain the constant tension of the optical fiber, avoiding the fluctuation of the optical fiber tension caused by unnecessary movement of the swing piece.

[0011] Further, the locking assembly includes a base, an actuating piece and a locking piece,

[0012] The base includes a bottom plate and first and second vertical plates arranged in parallel, and the first and second vertical plates are connected through the bottom plate. The first and second vertical plates are embedded with first and second sliding sleeves, respectively.

[0013] The locking piece includes first and second sliding rods, first and second clamping pieces. The first sliding rod is sleeved in the first sliding sleeve of the first vertical plate and the second sliding sleeve of the second vertical plate at both ends, respectively, and slides in the first sliding sleeve. The second sliding rod is sleeved in the first sliding sleeve of the first vertical plate and the second sliding sleeve of the second vertical plate at both ends, respectively, and slides in the second sliding sleeve. The first sliding rod is arranged in parallel with the second sliding rod.

[0014] The first clamping piece is connected with the first sliding rod, and the first clamping piece is close to the first vertical plate. The second clamping piece is connected with the second sliding rod, and the second clamping piece is close to the second vertical plate.

[0015] The second clamping piece is provided with a first through hole, and the first sliding rod passes through the first through hole and slides in the first through hole. The first and second clamping pieces extend towards the first connecting shaft to form a first clamping part, and the first clamping part embraces the first connecting shaft.

[0016] The actuating piece is connected with the first and second sliding rods, and the actuating piece is used to push the first and second sliding rods to slide relatively.

[0017] The base is composed of a bottom plate and first and second vertical plates on two sides, forming a stable support structure, and two sliding sleeves, i.e. a first sliding sleeve and a second sliding sleeve, are embedded on the two vertical plates to provide a sliding path for the locking member; the locking member includes two parallel sliding rods (a first sliding rod and a second sliding rod) and two clamping members (a first clamping member and a second clamping member), the sliding rods realize sliding function through the sliding sleeves, and the clamping members are responsible for clamping the first connecting shaft; the starting member is connected to the first and second sliding rods to realize the locking action by pushing the two sliding rods.

[0018] Working principle: when the first connecting shaft needs to be locked, the operator applies force to the starting member to make the first and second sliding rods slide towards each other, and with the relative movement of the sliding rods, the first and second clamping members gradually approach each other, and finally their first clamping parts tightly embrace the first connecting shaft to fix it, preventing the rotation of the first connecting shaft, thereby indirectly fixing the position of the swing member and reducing its swing amplitude; when the locking state needs to be released, the operator reverses the operation of the starting member to make the first and second sliding rods slide away from each other, and with the movement of the sliding rods, the first clamping parts of the first and second clamping members loosen the first connecting shaft to allow the first connecting shaft to rotate, restoring the activity of the swing member.

[0019] Further, the starting member includes a first fixed bolt, a second fixed bolt, a connecting plate and a force applying member,

[0020] The first fixed bolt is vertically arranged on the first sliding rod, and the second fixed bolt is vertically arranged on the second sliding rod;

[0021] The connecting plate is provided with a first slot and a second slot which are symmetric about the median plane of the connecting plate; the first fixed bolt passes through the first slot and slides in the first slot; the second fixed bolt passes through the second slot and slides in the second slot;

[0022] The force applying member is connected to the connecting plate, and the connecting plate is used to receive the force applied by the force applying member to push the first and second sliding rods to slide relative to each other.

[0023] When the first connecting shaft needs to be locked, the operator applies a force to the connecting plate through the force applying member, and the connecting plate starts to rotate after receiving the force; with the rotation of the connecting plate, the first fixing pin and the second fixing pin slide in the first slot and the second slot respectively; since the first slot and the second slot are symmetrical about the median plane of the connecting plate, rotating the connecting plate will make the first fixing pin and the second fixing pin gradually approach, drive the first sliding rod and the second sliding rod to slide towards each other, and make the first clamping member and the second clamping member gradually approach and finally embrace the first connecting shaft to fix it; when the distance between the first fixing pin and the second fixing pin is the shortest, the operator continues to apply a force to the connecting plate through the force applying member, and the connecting plate continues to rotate, so that the first fixing pin and the second fixing pin gradually move away, drive the first sliding rod and the second sliding rod to slide away from each other, and make the first clamping member and the second clamping member gradually separate to release the first connecting shaft and allow it to rotate.

[0024] Further, the frame body is further provided with a fiber releasing assembly, the fiber releasing assembly comprising a fiber releasing wheel, a second connecting shaft and a second driver, the output shaft of the second driver being connected to the second connecting shaft, and the other end of the second connecting shaft being connected to the fiber releasing wheel; the second driver is used to drive the fiber releasing wheel to rotate to release the optical fiber wound on the fiber releasing wheel.

[0025] When the optical fiber is released, the second driver is started, the output shaft of the second driver drives the second connecting shaft to rotate, and then the fiber releasing wheel is rotated, the rotating fiber releasing wheel releases the optical fiber wound thereon, and the released optical fiber passes through the tension wheel; the first driver drives the first connecting shaft to rotate to indirectly control the swing amplitude of the swing member, and the swing of the swing member adjusts the tension of the optical fiber.

[0026] Further, the locking member further comprises a third clamping member and a fourth clamping member, the third clamping member is connected to the first sliding rod, and the third clamping member is close to the first vertical plate; the fourth clamping member is connected to the second sliding rod, and the fourth clamping member is close to the second vertical plate.

[0027] The third clamping member is provided with a second through hole, the second sliding rod passes through the second through hole and slides in the second through hole; the third clamping member and the fourth clamping member extend towards the second connecting shaft to form a second clamping part; the second clamping part embraces the second connecting shaft.

[0028] The first connecting shaft is locked by the first clamping part, and the second connecting shaft is locked by the second clamping part, so that the first connecting shaft and the second connecting shaft are locked at the same time when the wire supply device rotates, the rotation of the fiber releasing wheel and the tension wheel due to external factors is reduced, and the tension of the optical fiber from the fiber releasing wheel to the tension wheel is kept stable.

[0029] Further, the first clamping member and the third clamping member are connected, and the second clamping member and the fourth clamping member are connected.

[0030] The first clamping piece and the third clamping piece, and the second clamping piece and the fourth clamping piece are connected into a whole, which is convenient for installation and simplifies the clamping structure.

[0031] Further, the middle parts of the first clamping piece and the second clamping piece are connected through a first spring, and the first spring is arranged in parallel with the first sliding rod.

[0032] The middle parts of the third clamping piece and the fourth clamping piece are connected through a second spring, and the second spring is arranged in parallel with the first sliding rod.

[0033] The first spring provides a continuous elastic force between the first clamping piece and the second clamping piece, and the first clamping piece and the second clamping piece are opened by the elastic force after the first connecting shaft is released, so as to prepare for the next clamping; similarly, the second spring provides a continuous elastic force between the third clamping piece and the fourth clamping piece, and the third clamping piece and the fourth clamping piece are opened by the elastic force after the second connecting shaft is released, so as to prepare for the next clamping. The first spring and the second spring also absorb external force and buffer external vibration.

[0034] Further, the force applying piece comprises a first connecting rod and a second connecting rod, the first connecting rod is connected with the connecting plate, and the second connecting rod is arranged vertically on the first connecting rod; when the second connecting rod is subjected to force, the connecting plate rotates.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments and the description thereof are only used to explain the present application and do not limit the present application.

[0048] First embodiment:

[0049] A wire supply device for winding fiber ring, the wire supply device is used for connecting a follow-up disc or a wire arranging device, when the wire supply device is connected with the follow-up disc, the wire supply device rotates with the follow-up disc; when the wire supply device is connected with the wire arranging device, the wire supply device moves with the wire arranging device; the wire supply device comprises a frame body 1, the frame body 1 is provided with a tension adjusting assembly 3 and a locking assembly 4, the locking assembly 4 is arranged beside the tension adjusting assembly 3;

[0050] The tension adjusting assembly 3 comprises a tension wheel 31, a swing piece 34, a first connecting shaft 35 and a first driver 36 (a stepping motor can be used), the swing piece 34 comprises a swing rod 33 and a connecting rod 32, the connecting rod 32 and the first connecting shaft 35 are vertically arranged at two end portions of the swing rod 33; the other end portion of the connecting rod 32 is connected with the tension wheel 31; the first connecting shaft 35 is connected with an output shaft of the first driver 36, and the first driver 36 is used for driving the first connecting shaft 35 to rotate.

[0051] When the wire supply device is connected with the follow-up disc, the locking assembly 4 locks the first connecting shaft 35.

[0052] In order to ensure that the fiber has stable tension in the winding process, prevent the fiber from being damaged or the winding quality from being reduced due to the too large tension change, the locking assembly 4 is introduced, when the wire supply device is connected with the follow-up disc and rotates with the follow-up disc, the first driver 36 will not start, and the first connecting shaft 35 is preliminarily fixed, but the first connecting shaft 35 can still rotate under the action of external force, for example, the wire supply device rotates and is affected by the centrifugal force, so the mechanical locking is introduced, the first connecting shaft 35 is locked through the locking assembly 4, and the rotation of the first connecting shaft 35 is further limited; since the first connecting shaft 35 is connected with one end of the swing piece 34, when the first connecting shaft 35 is locked, the swing piece 34 also loses the ability of swinging through the first connecting shaft 35.

[0053] Specifically, the locking assembly 4 fixes the first connecting shaft 35 at a certain position through a mechanical mode, so that even if the follow-up disc drives the wire supply device to rotate, the swing piece 34 cannot swing greatly due to external factors. Since the swing of the swing piece 34 is limited, the position of the tension wheel 31 connected with the swing piece 34 is also relatively stable. The tension wheel 31 is directly in contact with the fiber, and the stability of the tension wheel 31 can effectively keep the fiber tension constant, and avoid the fiber tension fluctuation caused by unnecessary movement of the swing piece 34.

[0054] In a specific embodiment, the locking assembly 4 comprises a base 56, an actuating piece 63 and a locking piece 64,

[0055] The base 56 comprises a bottom plate 55, and a first vertical plate 41 and a second vertical plate 42 arranged in parallel, and the first vertical plate 41 and the second vertical plate 42 are connected by the bottom plate 55; the first vertical plate 41 and the second vertical plate 42 are embedded with a first sliding sleeve 43 and a second sliding sleeve 44;

[0056] The locking member comprises a first sliding rod 45, a second sliding rod 46, a first clamping member 47 and a second clamping member 48; the two ends of the first sliding rod 45 are respectively sleeved in the first sliding sleeve 43 of the first vertical plate 41 and the second vertical plate 42, and the first sliding rod 45 slides in the first sliding sleeve 43; the two ends of the second sliding rod 46 are respectively sleeved in the second sliding sleeve 44 of the first vertical plate 41 and the second vertical plate 42, and the second sliding rod 46 slides in the second sliding sleeve 44; the first sliding rod 45 and the second sliding rod 46 are arranged in parallel;

[0057] The first clamping member 47 is connected with the first sliding rod 45, and the first clamping member 47 is close to the first vertical plate 41; the second clamping member 48 is connected with the second sliding rod 46, and the second clamping member 48 is close to the second vertical plate 42;

[0058] The second clamping member 48 is provided with a first through hole, and the first sliding rod 45 passes through the first through hole and slides in the first through hole; the first clamping member 47 and the second clamping member 48 extend to the first connecting shaft 35 to form a first clamping part, and the first clamping part encircles the first connecting shaft 35;

[0059] The starting member 63 is connected with the first sliding rod 45 and the second sliding rod 46, and is used to push the first sliding rod 45 and the second sliding rod 46 to slide relative to each other.

[0060] The base 56 is composed of the bottom plate 55 and the first vertical plate 41 and the second vertical plate 42 on both sides, forming a stable support structure, and two sliding sleeves, i.e., the first sliding sleeve 43 and the second sliding sleeve 44, are embedded on the vertical plates on both sides to provide a sliding path for the locking member; the locking member comprises two sliding rods (the first sliding rod 45 and the second sliding rod 46) arranged in parallel and two clamping members (the first clamping member 47 and the second clamping member 48), the sliding rods realize the sliding function through the sliding sleeves, and the clamping members are responsible for clamping the first connecting shaft 35; the starting member 63 is connected with the first sliding rod 45 and the second sliding rod 46, and realizes the locking action by pushing the two sliding rods.

[0061] Working principle: when the first connecting shaft 35 needs to be locked, the operator applies force to the starting piece 63, causing the first slide rod 45 and the second slide rod 46 to slide towards each other. With the relative movement of the slide rods, the first clamping piece 47 and the second clamping piece 48 gradually approach each other, and finally their first clamping parts tightly embrace the first connecting shaft 35, fixing it in place and preventing it from rotating, thereby indirectly fixing the position of the swing piece 34 and reducing its swing amplitude; when the locking state needs to be released, the operator operates the starting piece 63 in the opposite direction, causing the first slide rod 45 and the second slide rod 46 to slide away from each other. With the movement of the slide rods, the first clamping part of the first clamping piece 47 and the second clamping piece 48 loosens the first connecting shaft 35, allowing the first connecting shaft 35 to rotate and restoring the activity of the swing piece 34.

[0062] Through the above locking mechanism, when the wire supply device follows the rotation of the moving disc, the first connecting shaft 35 is firmly fixed, which not only limits the swing of the swing piece 34, but also reduces the change in fiber tension caused by the swing. Specifically, when the swing of the swing piece 34 is strictly controlled, the position of the tension wheel 31 is more stable, and the fiber tension can be more evenly distributed, thereby ensuring the consistency of the tension during the winding process and improving the quality and reliability of the fiber winding; by utilizing the mechanical locking principle, effective fixation of the first connecting shaft 35 is achieved, thereby reducing the swing amplitude of the swing piece 34 and stabilizing the fiber tension.

[0063] In a specific embodiment, the starting piece 63 includes a first fixed bolt 51, a second fixed bolt 52, a connecting plate 57, and a force applying piece 62,

[0064] The first clamping piece 47 is sleeved on the first slide rod 45, the second clamping piece 48 is sleeved on the second slide rod 46, the first fixed bolt 51 vertically penetrates the first slide rod 45 and the first clamping piece 47, and the second fixed bolt 52 vertically penetrates the second slide rod 46 and the second clamping piece 48;

[0065] The connecting plate 57 is provided with a first slot 58 and a second slot 59 which are symmetric about the median plane of the connecting plate 57; the first fixed bolt 51 passes through the first slot 58, and the first fixed bolt 51 slides in the first slot 58; the second fixed bolt 52 passes through the second slot 59, and the second fixed bolt 52 slides in the second slot 59;

[0066] As shown in Figure 6 and Figure 7 The force applying piece 62 includes a first connecting rod 60 and a second connecting rod 61, the first connecting rod 60 is connected to the middle part of the connecting plate 57 between the first slot 58 and the second slot 59, and the bottom plate 55 is provided with a through hole through which the first connecting rod 60 extends out of the lower surface of the bottom plate 55; the second connecting rod 61 is vertically connected to one end of the first connecting rod 60 extending out of the lower surface of the bottom plate 55;

[0067] When the second connecting rod 61 is stressed, the connecting plate 57 rotates and pushes the first and second sliding rods 45 and 46 to slide relative to each other.

[0068] When the first connecting shaft 35 needs to be locked, the operator applies a force to the connecting plate 57 through the force applying member 62. After receiving the force, the connecting plate 57 starts to rotate. With the rotation of the connecting plate 57, the first and second fixed pegs 51 and 52 slide in the first and second slotted holes 58 and 59, respectively. Since the first and second slotted holes 58 and 59 are symmetrical about the median plane of the connecting plate 57, the rotation of the connecting plate 57 causes the first and second fixed pegs 51 and 52 to gradually approach each other, which in turn causes the first and second sliding rods 45 and 46 to slide towards each other, so that the first and second clamping members 47 and 48 gradually approach and finally embrace the first connecting shaft 35, fixing it. When the distance between the first and second fixed pegs 51 and 52 is the shortest, the operator continues to apply a force to the connecting plate 57 through the force applying member 62. The connecting plate 57 continues to rotate, causing the first and second fixed pegs 51 and 52 to gradually move away from each other, which in turn causes the first and second sliding rods 45 and 46 to slide away from each other, so that the first and second clamping members 47 and 48 gradually separate, releasing the first connecting shaft 35 and allowing it to rotate.

[0069] When the wire feeding device rotates with the capstan, the locking assembly 4 fixes the first connecting shaft 35, directly limiting the swing range of the swing member 34, reducing unnecessary swings caused by external factors, making the position of the tension wheel 31 more stable, and enabling more uniform distribution of fiber tension, ensuring consistency in tension during winding and improving the quality and reliability of fiber winding.

[0070] Second embodiment:

[0071] Based on the first embodiment, as shown in Figure 1 and Figure 4 , the frame body 1 is further provided with a fiber releasing assembly 2, which includes a fiber releasing wheel 21, a second connecting shaft 22, and a second driver 23 (which can be a stepper motor). The output shaft of the second driver 23 is connected to the second connecting shaft 22, and the other end of the second connecting shaft 22 is connected to the fiber releasing wheel 21. The second driver 23 is used to drive the rotation of the fiber releasing wheel 21, releasing the fiber wound on the fiber wheel.

[0072] When releasing the fiber, the second driver 23 is started, its output shaft drives the second connecting shaft 22 to rotate, and in turn drives the fiber releasing wheel 21 to rotate. The rotating fiber releasing wheel 21 releases the fiber wound on it, and the released fiber passes through the tension wheel 31. The first driver 36 drives the first connecting shaft 35 to rotate, indirectly controlling the swing amplitude of the swing member 34, and adjusting the tension of the fiber through the swing of the swing member 34.

[0073] Third embodiment:

[0074] On the basis of the second embodiment, as shown in Figures 4 to 7 The locking member further comprises a third clamping member 49 and a fourth clamping member 50. The third clamping member 49 is connected with the first sliding rod 45 and is close to the first vertical plate 41. The fourth clamping member 50 is connected with the second sliding rod 46 and is close to the second vertical plate 42.

[0075] The third clamping member 49 is provided with a second through hole, and the second sliding rod 46 passes through the second through hole and slides in the second through hole. The third clamping member 49 and the fourth clamping member 50 extend towards the second connecting shaft 22 to form a second clamping part. The second clamping part encircles the second connecting shaft 22.

[0076] The first clamping part locks the first connecting shaft 35, and the second clamping part locks the second connecting shaft 22. When the fiber supply device rotates, the first connecting shaft 35 and the second connecting shaft 22 are locked at the same time, which reduces the rotation of the fiber releasing wheel 21 and the tension wheel 31 caused by external factors, and keeps the tension of the optical fiber from the fiber releasing wheel 21 to the tension wheel 31 stable.

[0077] Working process of the locking assembly 4:

[0078] Locked state: when the fiber supply device is connected with the follow-up disc and rotates with it, the locking assembly 4 operates through the starting member 63 to make the first sliding rod 45 and the second sliding rod 46 slide towards each other. The first clamping part of the first clamping member 47 and the second clamping member 48 encircles the first connecting shaft 35 to fix it. The second clamping part of the third clamping member 49 and the fourth clamping member 50 encircles the second connecting shaft 22 to fix it.

[0079] Unlocked state: the starting member 63 operates reversely to make the first sliding rod 45 and the second sliding rod 46 move away from each other. The first clamping part loosens the first connecting shaft 35 to allow it to rotate. The second clamping part loosens the second connecting shaft 22 to allow it to rotate.

[0080] Fourth embodiment:

[0081] On the basis of the third embodiment, the first clamping member 47 and the third clamping member 49 are connected, which can be integrally provided. The second clamping member 48 and the fourth clamping member 50 are connected, which can be integrally provided, as shown in Figure 5 .

[0082] Connecting the first clamping member 47 and the third clamping member 49, and the second clamping member 48 and the fourth clamping member 50 into one whole not only facilitates installation, but also simplifies the clamping structure.

[0083] Fifth embodiment:

[0084] On the basis of the third or fourth embodiment, the middle part of the first and second clamping members 47 and 48 is connected by a first spring 53, which is arranged in parallel with the first slide rod 45;

[0085] The middle part of the third and fourth clamping members 49 and 50 is connected by a second spring 54, which is arranged in parallel with the first slide rod 45.

[0086] The first spring 53 provides a continuous elastic force between the first and second clamping members 47 and 48, which will open the first and second clamping members 47 and 48 after the release of the first connecting shaft 35, and prepare for the next clamping. Similarly, the second spring 54 provides a continuous elastic force between the third and fourth clamping members 49 and 50, which will open the third and fourth clamping members 49 and 50 after the release of the second connecting shaft 22, and prepare for the next clamping. The first and second springs 53 and 54 also absorb external force and buffer external vibration.
