Description

Technical Field

[0001] The invention relates to the technical field of optical fiber fusion splicing, and in particular to an automatic pushing device for a heat shrinkable sleeve of an optical fiber fusion splicer. Background Art

[0002] At present, after the main fiber optic fusion splicer is fused, the wind shield and the left and right pressure plates are manually opened, and the operator moves the heat shrink tubing so that the melting point is in the center of the heat shrink tubing, manually opens the cover of the heating device, and manually moves the heat shrink tubing to the heating furnace for heating. During the movement of the heat shrink tubing, manual operation can easily cause the fiber optic fusion point to break, which has a certain impact on the fusion time and quality, especially in emergency communications such as earthquakes and wartime repairs, which reduces work efficiency and fusion quality.

[0003] Therefore, in order to solve the problem that the above-mentioned manual operation affects the welding time and quality, a device can be designed to accelerate the overall welding time and ensure the welding quality. Summary of the invention

[0004] In order to overcome the problem that manual operation affects welding time and quality.

[0005] The technical solution of the present invention is: an automatic pushing device for heat shrinkable sleeve of optical fiber fusion splicer, comprising a moving device, a sliding device, a reinforcing device, a buffer device, a heater, a stabilizing bracket and an automatic flip cover device;

[0006] The moving device comprises a slideway embedded in the welding machine table; a two-wheel pulley is movably connected inside the slideway; an L-shaped bracket is inserted in the two-wheel pulley; a first magnet is installed in the top of the L-shaped bracket crossbar; the top of the L-shaped bracket crossbar is connected to one end of the tray spring; the other end of the tray spring is fixedly connected to the tray body; a first spring is installed between the left end of the slideway and the two-wheel pulley; a first motor is installed at the right end of the slideway; a pull wire is installed between the output shaft of the first motor and the two-wheel pulley;

[0007] The sliding device includes a second motor embedded in the welding machine table; the output shaft end of the second motor is fixedly connected to the first rotating shaft; the first rotating shaft is sleeved in the two holes of the rotating shaft hole; a second bracket is installed in the rotating shaft hole; the lower ends of the two inner second brackets are respectively fixedly connected to the first bracket; a blocking fence is arranged on the outer sides of the two first brackets; a limited position groove is arranged on the first bracket; a crossbeam is installed between the second brackets; the second bracket on the inner side is fixedly connected to the crossbeam through an inclined rod; the upper end of the inclined rod is connected to another second bracket on the outer side;

[0008] The reinforcement device includes an upper and lower clamping plate; the inner sides of the upper and lower clamping plates are fixedly connected with second magnets in sequence; rubber pads are embedded and installed inside the upper and lower clamping plates and the second magnets; the two second magnets are fixedly connected by a second spring;

[0009] The heater includes a V-shaped heating furnace, a Y-shaped bracket and a cover plate; the lower end of the Y-shaped bracket is fixedly connected to a third spring;

[0010] The stabilizing bracket comprises a concave groove; the loose-leaf at the right end of the concave groove is embedded in the left side of the welding machine through a second rotating shaft; and a top rod is fixedly connected to the lower end of the concave groove.

[0011] Preferably, in the preparation stage, the tray body and the heat shrink sleeve are placed in the left position, the heat shrink sleeve is placed and balanced by a stable bracket, the first magnet of the moving device is energized, the first magnet and the tray body clamp the heat shrink sleeve, after the fiber section is completed, the optical fiber is placed at both ends and fused, the second magnet is energized, the optical fiber is placed in the middle of the upper and lower clamping plates, the second magnet is energized, the magnetic force of the second magnet merges the upper and lower clamping plates, the rubber pad protects the optical fiber, and the optical fiber is fixed, the upper and lower clamping plates are sucked together, and the optical fiber is fixed relative to the fusion splicer. At the same time, the windshield and the left and right pressure plates automatically pop up, the first motor rotates to drive the pull wire to rotate and wind, the two-wheel pulley moves to the right, and the center of the heat shrink sleeve moves to the center line position of the fusion splicer, When the electromagnetic force of the first magnet is cut off and disappears, one side of the tray body slides down, the left side of the heat shrinkable sleeve is on the left clamping plate, and the right side of the heat shrinkable sleeve slides to the right clamping plate. The heat shrinkable sleeve is basically symmetrical on the left and right sides of the center line, and the two-wheel pulley continues to move right. With the help of the pulling force of the first spring, the tray body continues to move right with the two-wheel pulley to complete the movement of the heat shrinkable sleeve. Due to the large diameter of the cylindrical hole in the middle of the heat shrinkable sleeve, the friction between the optical fiber and the heat shrinkable sleeve is very small, and the movement of the heat shrinkable sleeve has almost no effect on the welding point, which further guarantees the welding quality. When the sliding device rises to a certain height, the first motor stops working, and the pulling force of the first spring pulls the two-wheel pulley back to the left, back to the initial position of the two-wheel pulley. After the welding is completed, the two-wheel pulley and the L-shaped bracket are removed and put into the storage box;

[0012] When the second magnet is powered off, the elastic force of the second spring opens the upper and lower clamps, the reinforcement device 3 opens, the optical fiber is relatively free, the second motor rotates, leading the first shaft to rotate, the first shaft rotates in the shaft hole, the two fulcrums of the shaft hole are connected to the optical fiber fusion machine table, the first bracket and the second bracket rise, the first bracket has a limiting groove, the heat shrinkable tube will have a process of embedding into the limiting groove, so as to ensure that the position of the heat shrinkable tube relative to the center line is relatively uniform left and right, and is perpendicular to the center line, the limiting groove is equivalent to a fine adjustment of the position, so that the heat shrinkable tube is in a horizontal position left and right in the limiting groove, which is conducive to the sliding of the heat shrinkable tube, the early upgrade speed of the first bracket is relatively slow, when After the heat shrink sleeve is embedded in the limiting groove, the first bracket rises at a faster speed. When the angle between the first bracket and the second bracket and the table of the fusion splicer is large, the heat shrink sleeve starts to slide at the limiting groove position. The cylindrical gap in the middle of the heat shrink sleeve is large. The sliding or rolling of the heat shrink sleeve has almost no effect on the fusion point of the optical fiber after fusion splicing, and will not cause the fusion point to break or increase the melting point loss of the fusion point. The sliding heat shrink sleeve will be drawn into the V-shaped heating furnace 51 of the heater 5. A buffer device 4 is arranged between the heater 5 and the second bracket. Two Y-shaped brackets are designed in the heater 5. The rising Y-shaped bracket buffers the vibration caused by the heat shrink sleeve sliding down and falling due to the height difference, so as not to affect the fusion quality.

[0013] In the first stage, the mobile device moves to the right on the first layer; in the second stage, after the heat shrink tubing moves to the middle position, the magnetic force of the first magnet disappears, one side of the tray body slides down, the left side of the heat shrink tubing is in the middle position of the left clamping plate, and the right side slides to the right clamping plate. The heat shrink tubing is basically symmetrical on the left and right sides of the center line, and the mobile device continues to move to the right and rises to the second layer. With the help of the tension of the tray spring, the tray body continues to move to the right following the mobile device. In the third stage, the second magnet is powered off, and the elastic force of the second spring opens the upper and lower clamping plates, and the optical fiber is relatively free. In the fourth stage, when the bracket device rises to a certain height, the mobile device moves to the left, returns to the original initial starting position, and descends a height. The first handling of the heat shrink tubing is completed. After the optical fiber end face is completed and the optical fiber is placed, the pressure plate and the wind shield are automatically closed, and the heat shrink tubing is moved to the left bracket and placed on the tray body. The heat shrink tubing is relatively stable.

[0014] The included angle between the two Y-shaped brackets is relatively large, and one side of the Y-shaped bracket has a smaller included angle than the sliding device, allowing the heat shrink tubing to slide or roll relatively slowly on the second bracket, which is beneficial to buffering the sliding speed. There is a third spring under the Y-shaped bracket. The weight of the heat shrink tubing makes the Y-shaped bracket drop, which is consistent with the V-shaped heating furnace. The third spring is beneficial to buffering protection of the heat shrink tubing. The third spring triggers the V-shaped heating furnace to heat, and at the same time the cover is closed to play a role in heat preservation.

[0015] Preferably, the automatic cover-turning device is installed on the rear side of the upper end of the welding machine table; the automatic cover-turning device is arranged on the rear side of the heater.

[0016] Preferably, the second bracket is connected or welded to the first shaft socket.

[0017] Preferably, the buffer device is installed between the slide device and the heater; the buffer device is fixedly connected to the first rotating shaft.

[0018] Preferably, the two supporting points of the rotating shaft hole are connected to the table top of the optical fiber fusion splicer; and the rotating shaft hole is embedded with a bearing for installing the rotating shaft hole.

[0019] Preferably, two Y-shaped brackets are provided; the opening angles of the V-shaped heating furnace and the Y-shaped bracket match.

[0020] Preferably, the loose-leaf and the second rotating shaft are engaged; the second rotating shaft is embedded in the left platform edge of the optical fiber fusion splicer; two push rods are provided, and the push rods are inserted into the hole groove on the left side of the fusion splicer.

[0021] The beneficial effects of the present invention are as follows: the automated pushing design shortens the time from welding to heating, saves time for making the optical fiber end face, accelerates the overall welding time, further improves the protection of the welding point, and ensures the welding quality. The heat shrinkable sleeve starts to slide or roll in the bracket groove position, and the cylindrical gap in the middle of the heat shrinkable sleeve is relatively large. The sliding or rolling of the heat shrinkable sleeve has almost no effect on the welding point of the optical fiber after welding, and will not cause the welding point to break or increase the melting point loss of the welding point. The Y-shaped bracket and the third spring buffer the vibration caused by the sliding and falling of the heat shrinkable sleeve due to the height difference to avoid affecting the welding quality. The rubber pad protects the optical fiber and fixes the optical fiber. The buffer device slows down the sliding or rolling speed of the heat shrinkable sleeve to reduce damage to the welding point.

[0038] When working, in the preparation stage, the tray body 15 and the heat shrinkable tube are placed in the left position, the heat shrinkable tube is placed and balanced by the stable bracket 6, the first magnet 14 of the mobile device 1 is energized, the first magnet 14 and the tray body 15 clamp the heat shrinkable tube, after the fiber section is completed, the optical fiber is placed at both ends and fused, the second magnet 34 is energized, the optical fiber is placed in the middle position of the upper and lower clamping plates 31, the second magnet 34 is energized, the magnetic force of the second magnet 34 makes the upper and lower clamping plates 31 merge, the rubber pad 32 protects the optical fiber, and the upper and lower clamping plates 31 are sucked together, and the optical fiber is fixed relative to the fusion splicer. At the same time, the windshield and the left and right pressure plates automatically pop up, the first motor 19 rotates to drive the pull wire 17 to rotate and wind, the two-wheel pulley 12 moves to the right, and after the center of the heat shrinkable tube moves to the center line position of the fusion splicer, the first magnet The electromagnetic force of the iron 14 is broken and disappears, and one side of the tray body 15 slides down. The left side of the heat shrinkable sleeve is in the middle position of the left clamping plate, and the right side of the heat shrinkable sleeve slides to the right clamping plate. The heat shrinkable sleeve is basically symmetrical on the left and right sides of the center line. It is then aligned by the sliding device 2, and the two-wheel pulley 12 continues to move right. The tray body 15, with the help of the pulling force of the first spring 18, follows the two-wheel pulley 12 to continue to move right, and the movement of the heat shrinkable sleeve is completed. Due to the large diameter of the cylindrical hole in the middle of the heat shrinkable sleeve, the friction between the optical fiber and the heat shrinkable sleeve is very small, and the movement of the heat shrinkable sleeve has almost no effect on the welding point, which further guarantees the welding quality. When the sliding device 2 rises to a certain height, the first motor 19 stops working, and the pulling force of the first spring 18 pulls the two-wheel pulley 12 back to the left, back to the initial position of the two-wheel pulley 12. After the welding is completed, the two-wheel pulley 12 and the L-shaped bracket 13 are removed and put into the storage box;

[0039] When the second magnet 34 is powered off, the elastic force of the second spring 33 opens the upper and lower clamps 31, the reinforcement device 3 opens, the optical fiber can move relatively freely, the second motor 21 rotates, leading the first shaft 22 to rotate, the first shaft 22 rotates in the shaft hole 27, the two fulcrums of the shaft hole 27 are connected to the optical fiber fusion machine table, the first bracket 23 and the second bracket 26 rise, the first bracket 23 has a limiting groove 25 which is located a certain distance above the horizontal center line, which is conducive to the adjustment of the heat shrinkable sleeve, the heat shrinkable sleeve will have a process of embedding into the limiting groove 25, thus ensuring that the position of the heat shrinkable sleeve relative to the center line is relatively uniform left and right, and perpendicular to the center line, the limiting groove 25 is equivalent to a fine adjustment of the position, so that the heat shrinkable sleeve is in a horizontal position left and right in the limiting groove 25, which is conducive to the sliding and rolling of the heat shrinkable sleeve. , the speed of upgrading the first bracket 23 is relatively slow in the early stage. When the heat shrinkable sleeve is embedded in the limiting groove 25, the first bracket 23 rises faster. When the angle between the first bracket 23 and the second bracket 26 and the table of the welding machine is large, the heat shrinkable sleeve starts to slide and roll at the position of the limiting groove 25. The gap between the cylinder in the middle of the heat shrinkable sleeve is large. The sliding or rolling of the heat shrinkable sleeve has almost no effect on the welding point of the optical fiber after welding and can be ignored. It will not cause the breakage of the welding point or increase the melting point loss of the welding point. The sliding heat shrinkable sleeve will be drawn into the V-shaped heating furnace 51 of the heater 5. A buffer device 4 is set between the heater 5 and the second bracket 26. Two Y-shaped brackets 52 are designed in the heater 5. The rising Y-shaped bracket 52 buffers the vibration caused by the sliding and falling of the heat shrinkable sleeve due to the height difference, so as not to affect the welding quality;

[0040] In the first stage, the mobile device 1 moves to the right at a lower position on the first layer; in the second stage, after the heat shrink sleeve moves to the middle position, the magnetic force of the first magnet 14 disappears, and one side of the tray body 15 slides down. The left side of the heat shrink sleeve is in the middle position of the left clamping plate, and the right side slides to the right clamping plate. The heat shrink sleeve is basically symmetrical on the left and right sides of the center line, and the mobile device 1 continues to move right and rises to the second layer. The tray body 15, with the help of the tension of the tray spring 16, follows the mobile device 1 to continue to move right. In the third stage, the second magnet 34 is powered off, and the elastic force of the second spring 33 opens the upper and lower clamping plates 31, so that the optical fiber can move relatively freely. In the fourth stage, when the bracket device rises to a certain height, the mobile device 1 moves to the left, returns to the original initial starting position, and descends to the original lowest position. The first handling of the heat shrink sleeve is completed.

The heat shrink sleeve is relatively stable;

[0041] The included angle of the two Y-shaped brackets 52 is relatively large, and one side of the Y-shaped bracket 52 has a smaller included angle than the sliding device 2, so that the heat shrinkable tube slides or rolls relatively slowly on the second bracket 26, which is beneficial to buffering the sliding speed. There is a third spring 53 under the Y-shaped bracket 52. The weight of the heat shrinkable tube makes the Y-shaped bracket 52 drop and match the V-shaped heating furnace 51. The third spring 53 is beneficial to the buffering protection of the heat shrinkable tube. The third spring 53 triggers the V-shaped heating furnace 51 to heat, and at the same time the cover plate 54 is closed to play a role of heat preservation.

[0042] Through the above steps, the automated push design shortens the welding and heating time, saves time to make the optical fiber end face, speeds up the overall welding time, further improves the protection of the welding point, and ensures the welding quality. The sliding or rolling of the heat shrink tube has almost no effect on the welding point of the optical fiber after welding, and will not cause the welding point to break or the welding point loss to increase, so as to solve the problem that manual operation affects the welding time and quality.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
