Description

Technical Field

[0001] This invention relates to the field of optical fiber fusion splicer technology, specifically a dust removal and anti-interference optical fiber fusion splicer. Background Technology

[0002] A fiber optic fusion splicer is a high-tech instrument that combines optics, electronics, and precision mechanics. It is mainly used for the construction and maintenance of optical cables in optical communication. Its working principle is to use a high-voltage electric arc to melt the cross-sections of two optical fibers while a high-precision motion mechanism smoothly advances them, fusing the two optical fibers into one, thereby achieving coupling of the optical fiber mode field and ensuring effective signal transmission. In the current technology, it is difficult to clean some dead corners in the fusion splicing area of ​​the fusion splicer, resulting in dust accumulation in the fusion area, which affects the fusion quality.

[0003] Patent CN206161895U discloses a dust-removing and interference-preventing fiber optic fusion splicer. This patent includes a chassis with an operating table on top. An automatic heat stripper is located on one side of the operating table, a heat shrink tubing heating groove is located on the other side of the automatic heat stripper, a cleaver is located on the other side of the heat shrink tubing heating groove, an electrostatic precipitator is located on one side of the wind shield, a cleaner is located on one side of the electrostatic precipitator, a dust collector ventilation port is located on the other side of the wind shield, an electrostatic precipitator control switch is located on one side of the dust collector ventilation port, and a cleaner control switch is located on the other side of the electrostatic precipitator control switch. The electrostatic precipitator removes charged dust from the working parts, while the cleaner and dryer remove other oily impurities. This design is convenient, quick, simple, and easy to operate, saving time while ensuring machine cleanliness and improving work efficiency. Although this patent solves the aforementioned problems, it still has limitations, such as a fixed cleaning range and difficulty in completely cleaning some hard-to-reach areas. Therefore, this dust-removing and interference-preventing fiber optic fusion splicer is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dust removal and anti-interference optical fiber fusion splicer to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a dust removal and anti-interference fiber optic fusion splicer, comprising a fusion splicer body, a fusion splice groove formed on the top surface of the fusion splicer body, a control panel hinged to the front side of the fusion splicer body, a protective cover hinged to the top surface of the fusion splicer body, a first rotating curved plate hinged to the left side of the fusion splicer body, a second rotating curved plate hinged to the right side of the fusion splicer body, a reciprocating screw rotatably connected to the inner surface of the first rotating curved plate, a moving block connected to the circumferential surface of the reciprocating screw after movement, a miniature fan hinged to the lower surface of the moving block, and an elastic telescopic rod fixedly connected to the front side of the first rotating curved plate. The triangular abutment block is fixedly connected to the front end of the first elastic telescopic rod. The telescopic groove is opened on both sides of the fusion splicer body. The second elastic telescopic rod is fixedly connected to the inner surface of the telescopic groove. The triangular locking block is fixedly connected to the end of the second elastic telescopic rod near the first elastic telescopic rod. The sliding groove locking block is fixedly connected to the rear side of the moving block. An internal cleaning device for fine cleaning of the fiber clamping part is provided above the fusion splicer body. A shielding device to prevent dust from drifting to the surroundings is provided above the fusion splicer body. A motor is fixedly connected to the left end of the reciprocating screw, and the motor is fixedly connected to the left side of the first rotating curved plate. The right end of the reciprocating screw and the left side of the second rotating curved plate are also fixedly connected. The side-rotating connection is used, with the rear end of the elastic telescopic rod one and the front side of the rotating curved plate two fixedly connected. Open the protective cover on the welding machine body, then rotate the rotating curved plate one. The rotating curved plate one moves to the top of the welding tank via a reciprocating screw, driving the moving block and the micro fan. Start the micro fan, which blows up the dust adhering to the parts in the welding tank. Start the motor, which drives the reciprocating screw to rotate. At this time, move the lifting slide plate downwards, causing it to contact the welding machine body and generate friction, thus causing the moving block to move back and forth. The moving block drives the micro fan to move back and forth. When rotating the rotating curved plate one and the rotating curved plate two stops, pull the triangular abutment block forward. After the inclined surface of the contact block contacts the inclined surface of the triangular locking block, the triangular locking block is pushed into the telescopic groove by the guide of the inclined surface. When the triangular contact block continues to move forward and disengages from the triangular locking block, the elastic reset action of the second elastic telescopic rod pushes the triangular locking block out of the telescopic groove and inserts into the rear side of the triangular contact block. At this time, the triangular contact block is released and locked by the triangular locking block, thereby fixing the first and second rotating curved plates. After dust removal is completed, the triangular locking block is pressed towards the telescopic groove to release the triangular contact block from the restriction of the triangular locking block. The first elastic telescopic rod pulls the triangular contact block back to reset. At this time, the first and second rotating curved plates can be quickly rotated backward, thereby lowering the miniature fan.

[0006] Preferably, the internal cleaning device includes a lifting slide plate, a rotating rod, and alcohol swabs. The lifting slide plate is slidably connected to the inner surface of the slide block, the rotating rod is rotatably connected to the inner surface of the lifting slide plate, and the alcohol swabs are fixedly connected to the circumferential surface of the rotating rod. The internal cleaning device also includes rollers, friction convex plates, a liquid storage tank, a first side clamp, and a second side clamp. The rollers are fixedly connected to the circumferential surface of the rotating rod, the friction convex plates are fixedly connected to the front and rear sides of the inner wall of the welding groove, the liquid storage tank is fixedly connected to the left side of the welding machine body, the first side clamp is positioned above the welding machine body, the second side clamp is positioned above the welding machine body, the bottom end of the lifting slide plate is slidably connected to the upper surface of the welding machine body, the circumferential surface of the rollers and the upper surface of the friction convex plates are in contact with each other, and the circumferential surface of the rotating rod and the friction convex plates are in contact with each other. The right sides of the side clamps are in contact with each other, and the circumferential surface of the rotating rod is in contact with the left side of the second side clamp. The moving block moves left and right back and forth, driving the sliding block to move left and right back and forth. The sliding block drives the lifting slide plate to move left and right back and forth. The lifting slide plate drives the rotating rod to move left and right back and forth. The rotating rod drives the alcohol cotton to move left and right back and forth. The alcohol cotton cleans and disinfects the parts in the fusion splice groove. When the rotating rod moves left and right back and forth, it drives the roller to move left and right back and forth. When the roller moves, its circumferential surface contacts the upper surface of the friction protrusion, generating friction and causing it to roll. The roller rolls and drives the rotating rod to rotate inside the lifting slide plate. When the rotating rod rotates, it drives the alcohol cotton to rotate. After cleaning is completed, the lifting slide plate is pulled upward. The lifting slide plate, through the rotating rod, drives the alcohol cotton and the roller to rise and quickly move away from the fusion splice groove. At this time, the optical fiber can be placed into the fusion splice groove for splicing.

[0007] Preferably, the shielding device includes a first movable plate, a second movable plate, and a rubber connecting strip. The first movable plate is hinged to the upper surface of the welding machine body, the second movable plate is hinged to the upper surface of the first movable plate, and the rubber connecting strip is fixedly connected to the upper surface of the first movable plate. The shielding device also includes a ash discharge port, a baffle, a sliding elastic sheet, and V-shaped cleaning cotton. The ash discharge port is located at the bottom of the first side clamp, the baffle is hinged to the inner surface of the ash discharge port, the sliding elastic sheet is slidably connected to the lower surface of the second movable plate, the V-shaped cleaning cotton is fixedly connected to the rear side of the sliding elastic sheet, the rubber connecting strip is fixedly connected to the lower surface of the second movable plate, the sliding elastic sheet is slidably connected to the upper surface of the first movable plate, the V-shaped cleaning cotton is in contact with the upper surface of the first movable plate, the V-shaped cleaning cotton is in contact with the lower surface of the second movable plate, and the first and second side clamps are connected to the front end of the sliding elastic sheet. With a fixed connection, when the miniature fan blows up dust and impurities in the welding groove, the second movable plate is rotated backward and lifted. The second movable plate causes the rubber connecting belt to unfold, and the dust and impurities blown by the miniature fan from front to back fall into the space between the first and second movable plates for collection. After the miniature fan is turned off, the first movable plate is rotated backward and lifted, and then the baffle is opened to pour out the dust and impurities. When the rotating rod moves left and right, it causes the first and second side clamps to move left and right. The first and second side clamps cause the sliding elastic sheet to move left and right. The sliding elastic sheet causes the V-shaped cleaning cotton to move left and right. The V-shaped cleaning cotton scrapes off the dust and impurities adhering to the first and second movable plates. After the dust and impurities are poured out, the second movable plate is rotated forward and lowered. The second movable plate squeezes the sliding elastic sheet and the V-shaped cleaning cotton, causing the two ends of the sliding elastic sheet and the V-shaped cleaning cotton to come together, thus facilitating the retraction of the second movable plate.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This dust removal and anti-interference fiber optic fusion splicer uses a miniature fan to blow away dust adhering to the components in the splicing groove, preventing dust from interfering with fiber optic splicing and improving the splicing effect. The moving block drives the miniature fan to move back and forth, increasing the air outlet area of ​​the miniature fan, which in turn can blow away the dust in the corners of the splicing groove, improving the cleaning effect. The triangular contact block is locked by the triangular locking block, thereby fixing the rotating curved plate one and rotating curved plate two, making the operation of the miniature fan more stable and improving the dust removal effect.

[0010] 2. This dust removal and anti-interference fiber optic fusion splicer uses alcohol-soaked cotton to clean and disinfect the parts inside the splice groove, improving the cleaning effect and promoting the splicing quality. When the rotating rod rotates, it drives the alcohol-soaked cotton to rotate, increasing the contact area and friction between the alcohol-soaked cotton and the parts, further enhancing the disinfection and cleaning effect of the alcohol-soaked cotton on the parts. The lifting slide plate, driven by the rotating rod, moves the alcohol-soaked cotton and rollers upwards, thus quickly moving them away from the splice groove. At this point, the optical fiber can be placed into the splice groove for splicing, improving the ease of use of the device.

[0011] 3. This dust removal and anti-interference fiber optic fusion splicer collects dust and impurities blown from front to back by a miniature fan between movable plate one and movable plate two, preventing dust from being discharged and scattered during cleaning. Opening the baffle allows the dust and impurities to be poured out, improving processing efficiency. The V-shaped cleaning cotton scrapes off the dust and impurities adhering to movable plate one and movable plate two, preventing dust accumulation and improving the cleaning effect.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 One embodiment of the present invention is: a dust removal and anti-interference fiber optic fusion splicer, comprising a fusion splicer body 1, a fusion splice groove 2 formed on the top surface of the fusion splicer body 1, a control panel 3 hinged to the front side of the fusion splicer body 1, a protective cover 4 hinged to the top surface of the fusion splicer body 1, a rotating curved plate 5 hinged to the left side of the fusion splicer body 1, a rotating curved plate 51 hinged to the right side of the fusion splicer body 1, and a reciprocating screw 52 rotatably connected to the inner surface of the rotating curved plate 5, the circumferential surface of the reciprocating screw 52 being movable. A movable block 53 is connected to the rear, and a miniature fan 54 is hinged to the lower surface of the movable block 53. An elastic telescopic rod 55 is fixedly connected to the front side of the rotating curved plate 5. A triangular abutment block 56 is fixedly connected to the front end of the elastic telescopic rod 55. Telescopic grooves 57 are opened on both sides of the welding machine body 1. An elastic telescopic rod 58 is fixedly connected to the inner surface of the telescopic groove 57. A triangular locking block 59 is fixedly connected to the end of the elastic telescopic rod 58 near the elastic telescopic rod 55. A sliding groove locking block 510 is fixedly connected to the movable block 55. On the rear side of block 53, a miniature fan 54 blows up the dust adhering to the parts in the splice groove 2, preventing dust from interfering with the fiber splicing and improving the splicing effect. Moving block 53 drives the miniature fan 54 to move back and forth, increasing the air outlet area of ​​the miniature fan 54, which in turn can blow away the dust in the corners of the splice groove 2, improving the cleaning effect. An internal cleaning device 6 for fine cleaning of the fiber clamping part is set on the top of the splicer body 1. A shielding device 7 is set on the top of the splicer body 1 to prevent dust from drifting to the surroundings. A motor is fixedly connected to the left end of the reciprocating screw 52, ​​and the motor is fixedly connected to the left side of the rotating curved plate 1 5. The right end of the reciprocating screw 52 is rotatably connected to the left side of the rotating curved plate 2 51. The rear end of the elastic telescopic rod 1 55 is fixedly connected to the front side of the rotating curved plate 2 51. The triangular abutment block 56 is locked by the triangular locking block 59, thereby fixing the rotating curved plate 1 5 and the rotating curved plate 2 51, making the operation of the miniature fan 54 more stable and improving the dust removal effect.

[0022] Working principle: Open the protective cover 4 on the fusion splicer body 1, then rotate the first rotating plate 5. The first rotating plate 5 drives the moving block 53 and the micro fan 54 to move above the fusion splice groove 2 via the reciprocating screw 52. Start the micro fan 54, which blows away the dust adhering to the parts in the fusion splice groove 2, preventing dust from interfering with the fiber optic splicing and improving the splicing effect. Start the motor, which drives the reciprocating screw 52 to rotate. At this time, the lifting slide plate 61 is moved downward, so that the lifting slide plate 61 contacts the fusion splicer body 1 and generates friction, thereby causing the moving block 53 to move back and forth. The moving block 53 drives the micro fan 54 to move back and forth, increasing the air outlet area of ​​the micro fan 54, which in turn can blow away the dust in the corners of the fusion splice groove 2, improving the cleaning effect. When the first rotating plate 5 and the second rotating plate 51 stop rotating, pull the triangular abutment block 56 forward. The inclined surface of the triangular abutment block 56 and the micro fan 54 move back and forth. After the inclined surface of the triangular locking block 59 contacts, the triangular locking block 59 is pushed into the telescopic groove 57 by the guide of the inclined surface. When the triangular abutment block 56 continues to move forward and disengages from the triangular locking block 59, the elastic reset action of the elastic telescopic rod 58 pushes the triangular locking block 59 out of the telescopic groove 57 and inserts into the rear side of the triangular abutment block 56. At this time, the triangular abutment block 56 is released and is locked by the triangular locking block 59, thereby fixing the first rotating plate 5 and the second rotating plate 51, which makes the operation of the micro fan 54 more stable and improves the dust removal effect. After the dust removal is completed, the triangular locking block 59 is pressed towards the telescopic groove 57 to make the triangular abutment block 56 disengage from the restriction of the triangular locking block 59. The elastic telescopic rod 55 then pulls the triangular abutment block 56 to reset. At this time, the first rotating plate 5 and the second rotating plate 51 can be quickly rotated backward, thereby lowering the micro fan 54 and preventing damage to the micro fan 54.

[0023] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the internal cleaning device 6 includes a lifting slide plate 61, a rotating rod 62, and an alcohol cotton 63. The lifting slide plate 61 is slidably connected to the inner surface of the slide block 510, the rotating rod 62 is rotatably connected to the inner surface of the lifting slide plate 61, and the alcohol cotton 63 is fixedly connected to the circumferential surface of the rotating rod 62. The alcohol cotton 63 cleans and disinfects the parts in the welding groove 2, improving the cleaning effect and promoting the welding quality. When the rotating rod 62 rotates, it drives the alcohol cotton 63 to rotate, increasing the contact area and friction between the alcohol cotton 63 and the parts, further improving the disinfection and cleaning effect of the alcohol cotton 63 on the parts. The internal cleaning device 6 also includes a roller 64, a friction convex plate 65, a liquid storage tank 66, a first side clamp 67, and a second side clamp 68. Wheel 64 is fixedly connected to the circumferential surface of rotating rod 62. Friction protrusion 65 is fixedly connected to the front and rear sides of the inner wall of fusion splice groove 2. Liquid storage tank 66 is fixedly connected to the left side of fusion splicer body 1. Side clamp 1 67 is set above fusion splicer body 1. Side clamp 2 68 is set above fusion splicer body 1. The bottom end of lifting slide plate 61 is slidably connected to the upper surface of fusion splicer body 1. The circumferential surface of roller 64 is in contact with the upper surface of friction protrusion 65. The circumferential surface of rotating rod 62 is in contact with the right side of side clamp 1 67. The circumferential surface of rotating rod 62 is in contact with the left side of side clamp 2 68. Lifting slide plate 61 drives alcohol cotton 63 and roller 64 to rise through rotating rod 62, thereby quickly moving away from fusion splice groove 2. At this time, optical fiber can be placed into fusion splice groove 2 for splicing, improving the ease of use of the device.

[0024] Working principle: The reciprocating movement of the moving block 53 drives the sliding block 510 to reciprocate left and right. The sliding block 510 drives the lifting slide plate 61 to reciprocate left and right. The lifting slide plate 61 drives the rotating rod 62 to reciprocate left and right. The rotating rod 62 drives the alcohol cotton 63 to reciprocate left and right. The alcohol cotton 63 cleans and disinfects the parts in the welding groove 2, improving the cleaning effect and promoting the welding quality. When the rotating rod 62 reciprocates left and right, it drives the roller 64 to reciprocate left and right. When the roller 64 moves, its circumferential surface contacts the upper surface of the friction convex plate 65. Friction causes the roller 64 to roll, which in turn drives the rotating rod 62 to rotate within the lifting slide plate 61. As the rotating rod 62 rotates, it drives the alcohol cotton 63 to rotate, increasing the contact area and friction between the alcohol cotton 63 and the parts, thus further improving the disinfection and cleaning effect of the alcohol cotton 63 on the parts. After cleaning, the lifting slide plate 61 is pulled upwards, and the lifting slide plate 61, through the rotating rod 62, drives the alcohol cotton 63 and the roller 64 to rise, thus quickly moving away from the splice groove 2. At this time, the optical fiber can be placed into the splice groove 2 for splicing, improving the ease of use of the device.

[0025] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the shielding device 7 includes a first movable plate 71, a second movable plate 72, and a rubber connecting belt 73. The first movable plate 71 is hinged to the upper surface of the welding machine body 1, the second movable plate 72 is hinged to the upper surface of the first movable plate 71, and the rubber connecting belt 73 is fixedly connected to the upper surface of the first movable plate 71. Dust and impurities blown from front to back by the micro fan 54 fall between the first movable plate 71 and the second movable plate 72 for collection, preventing dust from being discharged and scattered during cleaning. Opening the baffle 75 allows the dust and impurities to be poured out, improving processing efficiency. The shielding device 7 also includes a dust discharge port 74, a baffle 75, a sliding elastic sheet 76, and a V-shaped cleaning cotton 77. The dust discharge port 74 is located on the side. At the bottom of clamping plate 67, baffle 75 is hinged to the inner surface of ash discharge port 74. Sliding elastic sheet 76 is slidably connected to the lower surface of movable plate 72. V-shaped cleaning cotton 77 is fixedly connected to the rear side of sliding elastic sheet 76. Rubber connecting strip 73 is fixedly connected to the lower surface of movable plate 72. Sliding elastic sheet 76 is slidably connected to the upper surface of movable plate 71. V-shaped cleaning cotton 77 is in contact with the upper surface of movable plate 71 and the lower surface of movable plate 72. Side clamping plate 67 and side clamping plate 68 are fixedly connected to the front end of sliding elastic sheet 76. V-shaped cleaning cotton 77 scrapes away dust and impurities adhering to movable plate 71 and movable plate 72, preventing dust accumulation and improving the cleaning effect.

[0026] Working principle: When the miniature fan 54 blows up the dust and impurities in the welding tank 2, the movable plate 72 is rotated and lifted backward. The movable plate 72 drives the rubber connecting belt 73 to unfold. At this time, the dust and impurities blown by the miniature fan 54 from front to back fall into the space between the movable plate 71 and the movable plate 72 for collection, preventing dust from being discharged and scattered during cleaning. After the miniature fan 54 is turned off, the movable plate 71 is rotated and lifted backward, and then the baffle 75 is opened to pour out the dust and impurities, improving processing efficiency. When the rotating rod 62 moves back and forth left and right, it drives the side clamps 67 and 68 to move back and forth left and right. Side clamp 67 and side clamp 68 drive the sliding elastic plate 76 to move back and forth, which in turn drives the V-shaped cleaning cotton 77 to move back and forth. The V-shaped cleaning cotton 77 scrapes away the dust and impurities adhering to the movable plate 71 and movable plate 72, preventing dust accumulation and improving the cleaning effect. After the dust and impurities are poured out, the movable plate 72 is rotated forward and lowered. The movable plate 72 squeezes the sliding elastic plate 76 and the V-shaped cleaning cotton 77, causing the two ends of the sliding elastic plate 76 and the V-shaped cleaning cotton 77 to come together, which makes it easier for the movable plate 72 to retract and facilitates the storage of the device.
