Description

Technical Field

[0001] The present invention relates to the technical field of optical communication equipment, and in particular to a fusion splicing device for optical cable connection. Background Art

[0002] During the construction and repair of optical cable lines, optical cable splicing operations must be performed. The optical cable splicing box, also known as the optical cable splicing box or the joint box, is a common device in optical cable communication, which is used to splice optical cables. Since the firmness of the optical cable in the splicing box directly affects the reliability of communication, the ability of the splicing box to fix the optical cable is an important indicator for evaluating the performance of the splicing box.

[0003] Application number CN201810558885.5 discloses an optical cable fixing device for an optical cable fusion box, including a box body and an optical cable, a sliding cabinet door is installed on one side of the box body, and two connecting pipes are relatively installed on the two opposite side walls of the box body. After the two optical cables enter the interior of the box body through the two connecting pipes, they are fixed by clamping devices respectively and then fused. A connecting piece is sleeved on the connection of the two optical cables; the connecting piece includes a first protective piece, a second protective piece and a tightening spring, the first protective piece is connected to the second protective piece, and the tightening spring is arranged between the first protective piece and the second protective piece. The optical cable fixing device for an optical cable fusion box described in the above invention can, on the one hand, have a good fixing effect on the optical cable without applying excessive clamping force to the surface of the optical cable, and will not damage the structure of the optical cable. At the same time, the device can provide good protection for the connection of the optical cable to prevent the optical cable from being corroded by the external environment and affecting the normal operation of the optical communication line.

[0004] The existing optical cable fusion operation device includes a fusion module and a heat shrink tube fixing module. The optical cable needs to be fixed at the fusion module for fusion first, and then transferred to the heat shrink tube fixing module to fix the heat shrink tube to the outside of the optical cable. However, after fusion of the optical cable, the optical cable is generally transferred manually and the heat shrink tube is moved to the fusion point of the optical cable. However, manual transfer is unstable and can easily cause the optical cable to bend. Especially in the process of moving the heat shrink tube, since the two ends of the optical cable are respectively grasped in two hands, the optical cable is easily bent or even broken. At this time, it needs to be re-fused, which is more troublesome.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the invention

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0039] like Figures 1 to 11 As shown, the present invention provides a fusion splicing device for optical cable connection, comprising: a box body 1; a fixing mechanism 3 for fixing the optical cable; and a fusion splicing mechanism 2 for fusing the fixed optical cable.

[0040] The welding mechanism 2 includes: an upper welding seat 21 and a lower welding seat 22, the end surfaces of the upper welding seat 21 and the lower welding seat 22 that are close to each other are vertically correspondingly provided with welding grooves 5 and heating grooves 6, sleeves 25 fixedly installed on the upper welding seat 21 and the lower welding seat 22 respectively, a movable rod 24 movably installed in the sleeve 25, a connecting rod 26 fixedly installed on the sleeve 25, an arc groove 23 opened in the box body 1, a driving component 27 that drives the upper welding seat 21 and the lower welding seat 22 to move along the path of the arc groove 23, a first positioning component 28 for positioning the upper welding seat 21 when it moves, and a second positioning component 29 for positioning the lower welding seat 22 when it moves.

[0041] The optical cable that has been pre-stripped, cut, cleaned, and covered with a heat shrink tube is initially fixed by the fixing mechanism 3, and then the optical cable parts on the two optical cables are manually brought close to each other, and then the optical cables are kept fixed. At this time, the driving component 27 is started to drive the upper welding seat 21 and the lower welding seat 22 to weld the optical cables.

[0042] The driving assembly 27 includes: a threaded rod 275 rotatably mounted on the housing 1, a threaded seat 276 threadedly connected to the threaded rod 275, a limit rod 277 fixedly connected to the movable rod 24 and limiting the position of the threaded seat 276 when it moves, the limit rod 277 passes through the threaded seat 276, and both ends of the limit rod 277 are fixedly mounted in the housing 1, a driven gear 274 fixedly sleeved on the threaded rod 275, a power source 271 fixedly mounted on the housing 1, a driving gear 272 fixedly mounted on the output end of the power source, and a synchronous belt 273 meshingly mounted on the driving gear 272 and the driven gear 274; a tensioning wheel (not shown) for tensioning the synchronous belt 273 is installed on the housing 1, so that the synchronous belt 273 is always meshed with the driving gear 272 and the driven gear 274, thereby ensuring the synchronous rotation of the driving gear 272 and the driven gear 274.

[0043] Specifically, the starting power source 271 drives the driving gear 272 to rotate, and the driving gear 272 drives the synchronous belt 273 to rotate, thereby driving the two driven gears 274 to rotate, and the driven gear 274 drives the adjacent threaded rod 275 to rotate, and the threaded rod 275 drives the adjacent threaded seat 276 to move. Under the limiting action of the limiting rod 277, the threaded seat 276 moves along the axial direction of the threaded rod 275, and the threaded seat 276 drives the movable rod 24 to move, and the movable rod 24 drives the sleeve 25 to move, and the sleeve 25 drives the upper welding seat 21 and the lower welding seat 22 to move synchronously along the axial direction of the threaded rod 275 (that is, move in the horizontal direction). When the sleeve 25 moves, it can drive the connecting rod 26 to slide in the arc groove 23. When the connecting rod 26 moves along the path of the arc groove 23, it can drive the sleeve 25 to move the upper welding seat 21 and the lower welding seat 22 along the path of the arc groove 23 (that is, move in the vertical direction).

[0044] When the two connecting rods 26 are respectively located at one end of the adjacent arc groove 23, the end faces of the upper welding seat 21 and the lower welding seat 22 that are close to each other abut against each other; then, start the power source 271, so that the upper welding seat 21 and the lower welding seat 22 move synchronously, and when the upper welding seat 21 and the lower welding seat 22 move to the center position of the adjacent arc groove 23, the upper welding seat 21 and the lower welding seat 22 move away from each other. At this time, the upper welding seat 21 and the lower welding seat 22 respectively move to the position where the vertical distance between them is the farthest. When the upper welding seat 21 and the lower welding seat 22 move to the other end of the adjacent arc groove 23, the end faces of the upper welding seat 21 and the lower welding seat 22 again abut against each other.

[0045] It should be noted here that when the upper welding seat 21 and the lower welding seat 22 are not in use, the upper welding seat 21 and the lower welding seat 22 are separated, that is, the upper welding seat 21 and the lower welding seat 22 are moved to the center position of the adjacent arc groove 23. At this time, the upper welding seat 21 and the lower welding seat 22 are respectively moved to the position where the vertical distance between them is the farthest.

[0046] When two optical cables are to be welded, the power source 271 is started to rotate in the opposite direction, thereby driving the upper welding seat 21 and the lower welding seat 22 to approach each other in the vertical direction; at the same time, the upper welding seat 21 and the lower welding seat 22 approach each other in the horizontal direction toward the direction of the power source 271 until they move to one end of the arc groove 23, so that the welding grooves 5 on the upper welding seat 21 and the lower welding seat 22 are both in contact with the surface of the optical cable. At this time, the two optical cables are welded by the built-in welding devices of the upper welding seat 21 and the lower welding seat 22.

[0047] When the welding is completed, the fixing mechanism 3 is started to move the two heat shrink tube sleeves closer to each other so that the two heat shrink tube sleeves are welded inside and outside, and then the power source 271 is started to rotate forward, thereby driving the upper welding seat 21 and the lower welding seat 22 to move synchronously in the horizontal direction, while the upper welding seat 21 and the lower welding seat 22 move away from each other in the vertical direction until the upper welding seat 21 and the lower welding seat 22 move to the position where the vertical distance between them is the farthest, and then the power source 271 continues to rotate forward, driving the upper welding seat 21 and the lower welding seat 22 to move synchronously in the horizontal direction. At this time, the upper welding seat 21 and the lower welding seat 22 are close to each other again in the vertical direction, so that the heating grooves 6 on the upper welding seat 21 and the lower welding seat 22 are both in contact with the surface of the optical cable. At this time, the heat shrink tube sleeve is heated and melted by the heating element in the heating groove 6 to be fixed on the fiber surface of the optical cable.

[0048] When the heat shrink tube sleeve is heated and melted to be fixed on the fiber surface of the optical cable, the power source 271 is started again to rotate in the opposite direction, driving the upper welding seat 21 and the lower welding seat 22 to move synchronously in the horizontal direction. At the same time, the upper welding seat 21 and the lower welding seat 22 move in the opposite direction in the vertical direction, that is, the upper welding seat 21 and the lower welding seat 22 move away from each other in the vertical direction until the upper welding seat 21 and the lower welding seat 22 move to the position where the vertical distance between them is the farthest, and then the power source 271 stops running, and the welded optical cable is automatically unloaded through the fixing mechanism 3.

[0049] It is to be added here that the power source 271 is preferably: a motor.

[0050] The first positioning assembly 28 includes: a first fixed tube 281 fixedly mounted on the upper welding seat 21, a first connecting rod 282 movably mounted in the first fixed tube 281, and a first piston 283 slidably mounted in the first positioning tube; the first piston 283 is fixedly connected to the first connecting rod 282; the first connecting rod 282 is fixedly connected to the threaded seat 276.

[0051] When the upper welding seat 21 moves in the vertical direction, it can drive the first fixed tube 281 to move, and then the first connecting rod 282 and the first piston 283 can slide in the first fixed tube 281. Through the mutual cooperation of the first fixed tube 281, the first connecting rod 282, and the first piston 283, the upper welding seat 21 can be positioned in the vertical direction to avoid the upper welding seat 21 from shifting when moving in the vertical direction, thereby improving the stability of the upper welding seat 21 in the vertical direction.

[0052] The second positioning assembly 29 includes: a second fixed tube 291 fixedly mounted on the lower welding seat 22, a second connecting rod 292 movably mounted in the second fixed tube 291, and a second piston 293 slidably mounted in the second positioning tube; the second piston 293 is fixedly connected to the second connecting rod 292; the second connecting rod 292 is fixedly connected to the threaded seat 276.

[0053] When the lower welding seat 22 moves in the vertical direction, it can drive the second fixed tube 291 to move, and then the second connecting rod 292 and the second piston 293 can slide in the first fixed tube 281. Through the mutual cooperation of the second fixed tube 291, the second connecting rod 292, and the second piston 293, the lower welding seat 22 can be positioned in the vertical direction to avoid the lower welding seat 22 from offset when moving in the vertical direction, thereby improving the stability of the lower welding seat 22 in the vertical direction.

[0054] In the present invention, the upper welding seat 21 and the lower welding seat 22 are positioned in the vertical direction respectively by the cooperation of the first positioning component 28 and the second positioning component 29, so as to avoid the displacement of the upper welding seat 21 and the lower welding seat 22 when moving in the vertical direction, thereby ensuring the accuracy of the docking of the upper welding seat 21 and the lower welding seat 22.

[0055] The fixing mechanism 3 includes: a power source 31 fixedly mounted on the box body 1, a rotating plate 32 fixedly mounted on the output end of the power source 31, a clamping member 33 fixedly mounted on the rotating plate 32, a guide plate 34 for guiding the clamping member 33 when it rotates, a conveying component 35 for conveying the clamped optical cable into the box body 1, and a discharge trough 36 opened on the box body 1.

[0056] Two groups of fixing mechanisms 3 are provided, which are symmetrically arranged on the box body 1 , and multiple groups of clamping members 33 are provided, which are evenly distributed in a ring shape on the corresponding rotating plates 32 .

[0057] The clamping member 33 includes: a first arc plate 331 fixedly mounted on the rotating plate 32 , and a second arc plate 332 hingedly connected to the first arc plate 331 ; a torsion spring is installed at the hinge between the first arc plate 331 and the second arc plate 332 .

[0058] It should be noted here that when the clamping member 33 is in a normal state, due to the elastic force of the torsion spring, the first arc plate 331 and the second arc plate 332 are in an open state; and a limit block (not shown) is set between the first arc plate 331 and the second arc plate 332 to limit the opening angle of the first arc plate 331 and the second arc plate 332.

[0059] The guide plate 34 is divided into a contraction section and a uniform section; the contraction section is arranged in an arc shape, and the arc angle gradually approaches the rotating plate 32; the uniform section is arranged in an arc shape, and the distance between the uniform section and the rotating plate 32 is always the same.

[0060] When the power source 2 31 drives the rotating plate 32 to rotate, the rotating plate 32 drives the clamping member 33 to rotate. When the second arc plate 332 in the clamping member 33 fits against the inner side of the guide plate 34 and enters the contraction section of the guide plate 34, it moves along the limiting path of the guide plate 34 under the limiting of the guide plate 34. Since the limiting block limits the opening angle of the first arc plate 331 and the second arc plate 332, the second arc plate 332 cannot be opened to a larger angle after fitting against the guide plate 34, and can only move along the path of the guide plate 34, so that the opening angle of the first arc plate 331 and the second arc plate 332 gradually decreases.

[0061] When the clamping member 33 moves to the highest position, the first arc plate 331 and the second arc plate 332 are just closed, and the first arc plate 331 and the second arc plate 332 can drive the torsion spring to deform;

[0062] Then the clamping member 33 continues to rotate with the rotating plate 32 and enters the uniform section of the guide plate 34. Under the limit of the uniform section of the guide plate 34, the first arc plate 331 and the second arc plate 332 remain in a closed state. When the clamping member 33 moves out of the limit range of the guide plate 34, due to the elastic force of the torsion spring, the first arc plate 331 and the second arc plate 332 can be driven to open and reset.

[0063] As attached Figure 3 As shown, there are four groups of clamping members 33 in the fixing mechanism 3. For the convenience of description, they are referred to as follows: the position of a group of clamping members 33 located on the left is the first position, the position of a group of clamping members 33 located on the top is the second position, the position of a group of clamping members 33 located on the right is the third position, and the position of a group of clamping members 33 located on the bottom is the fourth position.

[0064] Specifically, when the optical cable is welded, two optical cables that have been stripped, cut, cleaned, and covered with heat shrink tubes are placed in the two sets of clamps 33 at the first position respectively, and the two power sources 31 are started synchronously to drive the corresponding rotating plates 32 to rotate, and the two rotating plates 32 drive the adjacent clamps 33 to rotate; when the clamps 33 rotate from the first position to the second position, the first arc plate 331 and the second arc plate 332 are closed, so that the two optical cables that have been stripped, cut, cleaned, and covered with heat shrink tubes are automatically stored in the clamps 33;

[0065] When the clamping member 33 rotates to the second position, the power source 2 31 stops running. The second position is the loading position for optical cable processing. At this time, the two optical cables are manually pushed through the feed trough 36 and extended into the box body 1, so that the optical cable parts on the two optical cables are close to each other, and at this time, the two heat shrink tube sleeves and the corresponding optical cables are slidingly set, and the two heat shrink tube sleeves are retained in the corresponding clamping members 33. When the optical cable parts on the two optical cables are close to the required position, the power source 1 271 is started at this time, and then the upper welding seat 21 and the lower welding seat 22 are driven to move, so that the welding grooves 5 on the upper welding seat 21 and the lower welding seat 22 are both in contact with the surface of the optical cable. At this time, the two optical cables are welded by the built-in welding devices of the upper welding seat 21 and the lower welding seat 22.

[0066] It is to be added here that the second power source 31 is preferably: a motor.

[0067] When the welding is completed, the conveying assembly 35 is started to push the two heat shrink tube sleeves toward one side close to each other, so that the two heat shrink tube sleeves are welded inside and outside.

[0068] The conveying assembly 35 includes: a mounting plate 351 fixedly mounted on the box body 1, a power source three 352 fixedly mounted on the mounting plate 351, a threaded shaft 353 fixedly mounted on the output end of the power source three 352, a threaded plate 354 threadedly connected to the threaded shaft 353, a slider 355 fixedly mounted on the bottom of the threaded plate 354, and a moving part 356 that moves with the movement of the threaded plate 354; a sliding groove is opened on the mounting plate 351, and the slider 355 is slidably installed in the sliding groove.

[0069] Specifically, by starting power source three 352, the threaded shaft 353 is driven to rotate, the threaded shaft 353 drives the threaded plate 354 to move, and the threaded plate 354 drives the slider 355 to slide in the slide groove, so that the threaded plate 354 moves along the axial direction of the threaded shaft 353. When the threaded plate 354 moves, it can drive the moving part 356 to move. The moving part 356 pushes the two heat shrink tube sleeves toward the side close to each other, so that the two heat shrink tube sleeves are connected inside and outside.

[0070] It is to be added here that the power source three 352 is preferably: a motor.

[0071] The moving member 356 includes: a guide opening 3561 provided on the first arc-shaped plate 331, a slide bar 3562 fixedly installed in the guide opening 3561, a moving plate 3563 slidably installed on the slide bar 3562, a return spring 3564 for driving the moving plate 3563 to return, one end of the return spring 3564 being fixedly connected to the moving plate 3563, the other end of the return spring 3564 being fixedly connected to the inner wall of the guide opening 3561, a mounting groove provided on the moving plate 3563, a moving plate 3565 movably installed in the mounting groove, a linkage plate 3566 fixedly installed on the moving plate 3565, and a linkage spring 3567 fixedly installed between the moving plate 3565 and the mounting groove; when the heat shrink tube is sleeved on the clamping member 33, it is located between the linkage plate 3566 and the box body 1, and one end of the heat shrink tube sleeve abuts against a side of the linkage plate 3566 close to the box body 1.

[0072] That is, the threaded plate 354 pushes the movable plate 3563 to move, the movable plate 3563 drives the movable plate 3565 to move, and drives the reset spring 3564 to stretch, the movable plate 3565 drives the linkage plate 3566 to move, and the linkage plate 3566 pushes the two heat shrink tube sleeves toward the side close to each other, so that the two heat shrink tube sleeves pass through the feed groove 36, and the two heat shrink tube sleeves are connected inside and outside, and then the power source 271 is started, which drives the upper welding seat 21 and the lower welding seat 22 to move, so that the heating grooves 6 on the upper welding seat 21 and the lower welding seat 22 are both in contact with the surface of the optical cable, and the heat shrink tube sleeve is heated and melted by the heating element in the heating groove 6 to be fixed on the fiber surface of the optical cable.

[0073] After the heat shrink tube sleeve is heated and melted to be fixed on the fiber surface of the optical cable, first start the power source 1 271 to drive the upper welding seat 21 and the lower welding seat 22 to move, so that the upper welding seat 21 and the lower welding seat 22 are respectively moved to the position with the farthest vertical distance between them; then start the power source 352 to drive the threaded shaft 353 to rotate in the opposite direction, thereby driving the threaded plate 354 to reset. Since the threaded plate 354 has no pushing effect on the movable plate 3563, at this time, under the elastic force of the reset spring 3564, the movable plate 3563 can be driven to reset, and the movable plate 3563 drives the movable plate 3565 to reset, and the movable plate 3565 drives the linkage plate 3566 to reset.

[0074] At this time, the power source 2 31 is started again to drive the rotating plate 32 to rotate, thereby moving the clamping member 33 from the second position to the third position. Since the clamping member 33 is not limited by the guide plate 34, the elastic force of the torsion spring drives the first arc plate 331 and the second arc plate 332 to open. At this time, the first arc plate 331 and the second arc plate 332 have no fixing effect on the optical cable after the heating is completed. At this time, the optical cable slides out of the clamping member 33 and moves out of the box body 1 along the path of the discharge trough 36, thereby realizing automatic discharge of the optical cable after the heating is completed.

[0075] In the present invention, by setting the fixing mechanism 3, on the one hand, two optical cables that have been pre-processed, peeled, cut, cleaned, and sleeved with heat shrink tubes can be automatically stored in the clamping member 33, and when the storage is completed, the two optical cables that have been pre-processed, peeled, cut, cleaned, and sleeved with heat shrink tubes can be moved to the loading place for processing; on the other hand, the optical cable does not need to be moved during the entire processing process, so that the welding operation and the heat shrink tube fixing operation are stable and reliable, effectively avoiding the problem of bending or even breaking of the optical cable, and improving the welding quality of the optical cable; at the same time, the optical cable can be automatically unloaded after the welding and heating are completed, thereby improving work efficiency.

[0076] The fixing mechanism 3 further includes: an inclined block 37 fixedly mounted on the linkage plate 3566 , and a guide block 38 fixedly mounted in the guide opening 3561 .

[0077] When the linkage plate 3566 moves, the inclined block 37 can be driven to move. When the inclined block 37 moves to abut against the guide block 38, the inclined surface on the guide block 38 guides the inclined block 37, which can drive the inclined block 37 to move upward. The inclined block 37 drives the linkage plate 3566 to move upward, so that the linkage plate 3566 squeezes and fixes the optical cable, avoiding relative movement between the optical cable and the heat shrink tube when heated, making the welding operation and the heat shrink tube fixing operation more stable and reliable, further avoiding the problem of optical cable bending or even breakage, and greatly improving the welding quality of the optical cable.

[0078] When the linkage plate 3566 moves upward, it can drive the movable plate 3565 to move, and the movable plate 3565 drives the linkage spring 3567 to deform. When the threaded plate 354 is reset, it has no pushing effect on the movable plate 3563. At this time, the movable plate 3563 is reset by the elastic action of the reset spring 3564, and then the linkage plate 3566 is driven to move and reset along the axial direction of the threaded shaft 353. When the inclined block 37 is separated from the guide block 38, the movable plate 3565 can be reset by the elastic force of the linkage spring 3567, and the movable plate 3565 drives the linkage plate 3566 to move and reset in the vertical direction.

[0079] It is added here that, by moving the linkage plate 3566, on the one hand, the heat shrink tube sleeve can be driven to move to a desired position; on the other hand, after the heat shrink tube sleeve is moved to a desired position, the optical cable can be fixed.

[0080] The present invention cooperates with the welding mechanism 2 and the fixing mechanism 3 so that the upper welding seat 21 and the lower welding seat 22 can move synchronously in the horizontal direction and reciprocate in the vertical direction, so that the optical cable can complete the welding operation and the heat shrink tube fixing operation in the welding groove 5 and the heating groove 6 in turn. Since the optical cable is fixed in the whole process, the welding operation and the heat shrink tube fixing operation are stable and reliable, which effectively avoids the problem of bending or even breaking of the optical cable, and improves the welding quality of the optical cable.

[0081] It also includes: a cleaning mechanism 4 for cleaning the upper welding seat 21 and the lower welding seat 22;

[0082] The cleaning mechanism 4 includes: a first nozzle 42 fixedly installed in the box body 1, an air guide pipe 41 connecting the first nozzle 42 and the first fixed pipe 281, an air collecting pipe 44 fixedly installed in the box body 1, a connecting pipe 43 connecting the air collecting pipe 44 and the second fixed pipe 291, a second nozzle 45 connected to the air collecting pipe 44, and a discharge opening 46 opened on the box body 1.

[0083] In the present invention, two first nozzles 42 are provided, corresponding to the welding groove 5 and the heating groove 6 respectively. When the upper welding seat 21 and the lower welding seat 22 move away from each other in the vertical direction, the first fixed tube 281 and the second fixed tube 291 are driven to move;

[0084] At this time, the first piston 283 slides in the first fixed tube 281, thereby squeezing the gas in the first fixed tube 281, so that the gas in the two first fixed tubes 281 enters the corresponding first nozzles 42 through the adjacent air guide tubes 41, and is sprayed to the welding groove 5 and the heating groove 6 through the two first nozzles 42, so that the dust attached to the welding groove 5 and the heating groove 6 can be blown away, so that the welding groove 5 and the heating groove 6 are kept in a certain clean state, thereby ensuring the quality of optical cable welding.

[0085] The second piston 293 slides in the second fixed pipe 291, thereby squeezing the gas in the second fixed pipe 291, so that the gas in the two second fixed pipes 291 respectively enters the gas collecting pipe 44 through the adjacent connecting pipes 43, and is ejected through the second injection head 45. Since a plurality of second injection heads 45 are provided, they are linearly arranged along the axial direction of the gas collecting pipe 44;

[0086] The dust blown off by the first nozzle 42 falls into the bottom of the inner cavity of the box body 1. At this time, air is blown toward the bottom of the inner cavity of the box body 1 through a plurality of second nozzles 45, so as to clean the dust at the bottom of the inner cavity of the box body 1. The dust is discharged through the discharge opening 46, so as to realize automatic cleaning of the dust at the bottom of the inner cavity of the box body 1.

[0087] A viewing window is also installed on the box to facilitate observation of the fusion of the optical cable.
