Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber coating stripping, and in particular to a fiber stripping device. Background Art

[0002] Thermal stripping pliers are generally used to remove the coating of small-diameter optical fibers. Existing thermal stripping pliers can generally only strip the tail of small-diameter pump fibers or signal fibers, and the stripping ends have many burrs and are prone to cracks. Specifically, existing thermal stripping pliers have the following defects: 1. Existing thermal stripping pliers usually use a pair of "V"-shaped cutting edges. When the fiber diameter is large, the distance between the upper and lower blades becomes larger, resulting in only a portion of the entire circle of the fiber coating being cut. The remaining portion of the fiber coating that is not cut off is passively pulled off. Therefore, using "V"-shaped cutting edges of thermal stripping pliers to remove the fiber coating will result in more burrs and cracks on the stripping edge. This problem is more obvious with larger fiber diameters. 2. Existing thermal stripping pliers can generally only strip the coating layer at one end of the optical fiber, and cannot strip the middle window of the optical fiber, that is, the middle coating layer of the optical fiber; 3. The existing thermal stripping pliers have a single fiber stripping knife structure, and the fiber stripping debris is not automatically cleaned in time, or is only blown by compressed air, which cannot ensure the cleanliness of the fiber stripping surface. Therefore, when turning 180 degrees again to strip the other end, the debris may get stuck in the knife or cause cracks and burrs on the stripping edge.

[0003] 4. The existing thermal stripping pliers only have a single fiber stripping knife structure, and the fiber clamp is manually opened and closed, which cannot automatically adjust the position of the required fiber stripping port, and cannot achieve fiber stripping of the middle section window of the optical fiber through a single clamping.

[0004] Therefore, a new fiber stripping device is urgently needed to solve the technical problems of the existing thermal stripping pliers. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0021] As used herein, the term "including" and its variations are open-ended, i.e., "including but not limited to." The term "based on" means "based, at least in part, on." The term "one embodiment" means "at least one embodiment," the term "another embodiment" means "at least one additional embodiment," and the term "some embodiments" means "at least some embodiments." Other terms are defined in the following description.

[0022] In the embodiments of the present invention, the thermal stripping pliers are generally used to remove the coating layer at the tail of a small-diameter optical fiber. Existing thermal stripping pliers can only strip pump fibers or signal fibers with smaller diameters, and the stripping ends have many burrs and are prone to cracks. Specifically, existing thermal stripping pliers have the following defects: 1. Existing thermal stripping pliers usually use a pair of "V"-shaped cutting edges. When the fiber diameter is large, the distance between the upper and lower blades becomes larger, resulting in only a portion of the entire circle of the fiber coating being cut. The remaining portion of the fiber coating that is not cut off is passively pulled off. Therefore, using "V"-shaped cutting edges of thermal stripping pliers to remove the fiber coating will result in more burrs and cracks on the stripping edge. This problem is more obvious with larger fiber diameters. 2. Existing thermal stripping pliers can generally only strip the coating layer at one end of the optical fiber, and cannot strip the middle window of the optical fiber, that is, the middle coating layer of the optical fiber; 3. The existing thermal stripping pliers have a single fiber stripping knife structure, and the fiber stripping debris is not automatically cleaned in time, or is only blown by compressed air, which cannot ensure the cleanliness of the fiber stripping surface. Therefore, when turning 180 degrees again to strip the other end, the debris may get stuck in the knife or cause cracks and burrs on the stripping edge.

[0023] 4. The existing thermal stripping pliers only have a single fiber stripping knife structure, and the fiber clamp is manually opened and closed, which cannot automatically adjust the position of the required fiber stripping port, and cannot achieve fiber stripping of the middle section window of the optical fiber through a single clamping.

[0024] Therefore, a new fiber stripping device is urgently needed to solve the technical problems of the existing thermal stripping pliers.

[0025] In order to solve the technical problems existing in the related art, the embodiment of the present invention provides a fiber stripping device 100, see Figure 1 , Figure 1 FIG. 1 is a structural diagram of a fiber stripping device provided by an embodiment of the present invention. Figure 1 As shown, the fiber stripping device 100 provided in the embodiment of the present invention includes: an optical fiber heating structure 110, a first fiber stripping knife structure 120, a second fiber stripping knife structure 130, a first optical fiber clamp structure 140 and a second optical fiber clamp structure 150; In which, the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 are arranged on the optical fiber heating structure 110 and are located at opposite ends of the optical fiber heating structure 110, and the optical fiber heating structure 110 is used to heat the coating layer of the optical fiber to be processed, and the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 respectively have a circumferential cutting edge for stripping the coating layer of the optical fiber to be processed; the first optical fiber clamp structure 140 and the second optical fiber clamp structure 150 are respectively arranged on the side of the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 away from the optical fiber heating structure 110, and the first optical fiber clamp structure 140 and the second optical fiber clamp structure 150 are respectively used to clamp or loosen the non-stripping part of the optical fiber to be processed exposed outside the optical fiber heating structure 110, and the first optical fiber clamp structure 140 and the second optical fiber clamp structure 150 are both used to move on a target path, which is a path on a straight line parallel to the straight line where the axis of the optical fiber to be stripped is located.

[0026] It should be noted that the target path provided in this embodiment can be a path on a straight line parallel to the straight line on which the axis of the optical fiber to be stripped is located, or it can be a path on a straight line on which the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 are located, or it can be a path on other straight lines parallel to the straight line on which the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 are located. As long as the limiting position and limiting direction of the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 for the processed optical fiber, that is, the axis of the optical fiber to be stripped, are kept on the same straight line as the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130, no specific limitation is made here.

[0027] In this embodiment, the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 provided in this embodiment work separately to strip the opposite ends of the optical fiber to be processed respectively, so that not only can the tail fiber at any end of the optical fiber to be processed be stripped by one fiber stripping knife structure (the first fiber stripping knife structure 120 or the second fiber stripping knife structure 130) to achieve the purpose of tail end stripping; the opposite ends of the optical fiber to be processed can also be stripped twice by the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 respectively to achieve the purpose of middle section stripping.

[0028] Specifically, this embodiment configures a group of fiber stripping knife structures at the left and right ends of the optical fiber heating structure 110, so that the fiber stripping knife structures on both sides share a heating module, thereby effectively improving the fiber stripping efficiency of single tail stripping and two middle stripping.

[0029] In some embodiments, the fiber stripping device 100 provided in this embodiment may further include a driving structure 160, wherein the driving structure 160 is respectively connected to the first fiber clamp structure 140 and the second fiber clamp structure 150, and is used to drive the first fiber clamp structure 140 or the second fiber clamp structure 150 to move on the target path.

[0030] As an optional embodiment, the driving structure 160 provided in this embodiment may include a first motor 161, a second motor 165, a first gear 162, a second gear 166, a first rack 163, a second rack 167, a first slide rail 164 and a second slide rail 168; In which, the first slide rail 164 and the second slide rail 168 are respectively arranged on straight lines parallel to the target path, the first rack 163 is arranged on the first slide rail 164, and the end of the first rack 163 is connected to the first optical fiber clamp structure 140, the second rack 167 is arranged on the second slide rail 168, and the end of the second rack 167 is connected to the second optical fiber clamp structure 150; the first motor 161 is connected to the first gear 162, the first rack 163 is engaged with the first gear 162, the second motor 165 is connected to the second gear 166, and the second rack 167 is engaged with the second gear 166.

[0031] It should be noted that the first slide rail 164 and the second slide rail 168 provided in this embodiment can be two different slide rails, or they can share a slide rail. When the first slide rail 164 and the second slide rail 168 are two different slide rails, the first rack 163 and the second rack 167 are respectively arranged on the corresponding two different slide rails; when the first slide rail 164 and the second slide rail 168 are the same slide rail, the first rack 163 and the second rack 167 can be arranged on the same slide rail, and the first rack 163 and the second rack 167 can be two parts of the same rack. At the same time, the first slide rail 164 and the second slide rail 168 can be arranged on a straight line where the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 are located, or can be arranged on a straight line parallel to the straight line where the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 are located. As long as the limiting position and limiting direction of the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 for the processed optical fiber remain on the same straight line as the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130, no specific limitation is made here.

[0032] In this way, two sets of motors drive the gears to rotate respectively, so as to drive the rack to move in different directions, so that the fiber clamp structure connected to the end of the rack can also move accordingly, thereby independently realizing the left and right independent fiber stripping movement.

[0033] In some embodiments, see Figure 2 、 Figure 3a 、 Figure 3b as well as Figure 4 , Figure 2 This is a structural diagram of a fiber stripping knife structure provided by an embodiment of the present invention. Figure 3a This is a structural diagram of a first tool holder provided by an embodiment of the present invention. Figure 3b This is a structural diagram of a second tool holder provided by an embodiment of the present invention. Figure 4 Schematic diagram of the structure of the first blade and the second blade provided by the embodiment of the present invention. Figure 2 、 Figure 3a 、 Figure 3b as well as Figure 4 As shown, the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 provided in this embodiment both include a first knife seat 121 and a second knife seat 122, the first knife seat 121 is provided with a first blade mounting groove 1211, the first blade mounting groove 1211 is used to install the first blade 1212, the second knife seat 122 is provided with a second blade mounting groove 1221, the second blade mounting groove 1221 is used to install the second blade 1222; the first knife seat 121 and the second knife seat 122 are spliced ​​and connected in the relative directions of the notches of the first blade mounting groove 1211 and the second blade mounting groove 1221, and the first blade 1212 and the second blade 1222 installed in the first blade mounting groove 1211 and the second blade mounting groove 1221 are fitted together to form a ring cutting edge for stripping the coating layer of the optical fiber to be processed.

[0034] The first blade mounting slot 1211 and the second blade mounting slot 1221 provided in this embodiment can be equipped with blades of different specifications, thereby achieving the purpose of stripping optical fibers of different diameters. Specifically, in order to enable the first blade mounting slot 1211 and the second blade mounting slot 1221 to be equipped with blades of different specifications, thereby achieving the purpose of stripping optical fibers of different diameters, the first blade holder 121 and the second blade holder 122 provided in this embodiment can be provided with a first pin hole H1 on the side of the first blade mounting slot 1211 and the second blade mounting slot 1221, respectively. The first blade 1212 and the second blade 1222 can be provided with a second pin hole H2, respectively. The first pin hole H1 and the second pin hole H2 correspond to each other. The first blade 1212 and the second blade 1222 are fixed in the first blade mounting slot 1211 and the second blade mounting slot 1221 respectively by fixing pins that pass through the corresponding first pin hole H1 and second pin hole H2.

[0035] In this way, by setting a second pin hole H2 corresponding to the first pin hole H1 on blades of different specifications, when installing blades of different specifications into the blade mounting groove, the fixing pin shaft can be passed through the first pin hole H1 on the blade holder and the second pin hole H2 on the blade at the same time, thereby achieving the purpose of fixing blades of different specifications in the blade mounting groove of the blade holder, so that optical fibers of different diameters can be stripped by assembling blades of different specifications in the blade mounting groove.

[0036] At the same time, in order to achieve stable fiber stripping processing, the first knife seat 121 provided in this embodiment can also be provided with a fiber guide groove 1213, and the second knife seat 122 can also be provided with a groove 1223 matching the fiber guide groove 1213. The groove 1223 is used to provide an avoidance space for the fiber guide groove 1213 so that the first knife seat 121 and the second knife seat 122 can be tightly spliced ​​and connected.

[0037] The optical fiber guide groove 1213 provided in this embodiment is a V-shaped guide groove, so as to limit the position of the optical fiber to be processed.

[0038] In order to facilitate the tight splicing connection between the first tool seat 121 and the second tool seat 122, the first tool seat 121 provided in this embodiment may also be provided with a positioning pin shaft 1214, and the second tool seat 122 may also be provided with a positioning pin hole H3 matching the positioning pin shaft 1214. The first tool seat 121 and the second tool seat 122 are tightly spliced ​​and connected through the matching connection between the positioning pin shaft 1214 and the positioning pin hole H3, thereby effectively ensuring the stability of the connection between the first tool seat 121 and the second tool seat 122, thereby achieving the purpose of tight splicing connection between the first tool seat 121 and the second tool seat 122.

[0039] In some embodiments, to ensure the cleanliness of the blade surface during the fiber stripping process, this embodiment requires timely cleaning of debris generated during the fiber stripping process. Specifically, the first blade holder 121 provided in this embodiment may also be provided with a vacuum air duct interface 1215. A first vacuum chamber 1216 is also provided on the first blade holder 121 between the first blade mounting groove 1211 and the fiber guide groove 1213. A second vacuum chamber 1224 is also provided on the second blade holder 122 between the second blade mounting groove 1221 and the groove 1223. When the first and second blade holders 121 and 122 are spliced ​​together, the first and second vacuum chambers 1216 and 1224 communicate with the vacuum air duct interface 1215 to form a vacuum environment. To prevent debris from jamming the blade or causing cracks or burrs on the stripping edge, this embodiment connects the vacuum air duct interface 1215 to a vacuum dust removal system to promptly clean debris generated during the fiber stripping process, thereby maintaining a clean blade surface.

[0040] It should be noted that a vacuum air pipe interface 1215 may also be provided on the second knife holder 122 provided in this embodiment. This embodiment can effectively increase the suction force of the vacuum adsorption during the fiber stripping process by simultaneously performing vacuum adsorption on the vacuum cavities of the first knife holder 121 and the second knife holder 122, thereby improving the debris cleaning efficiency.

[0041] Optionally, the first blade holder 121 provided in this embodiment may further be provided with a mounting countersunk hole H4, so that the first blade holder 121 can be easily assembled to the optical fiber heating structure 110 through the mounting countersunk hole H4.

[0042] In some embodiments, see Figure 5 , Figure 5 FIG. 1 is a schematic structural diagram of a fiber clamp structure provided by an embodiment of the present invention. Figure 5As shown, the first optical fiber clamp structure 140 and the second optical fiber clamp structure 150 provided in this embodiment may include a cylinder 141, a push rod 142, a pressure block 143, a connecting rod 144, a base 145 and an optical fiber positioning groove 146; Among them, the cylinder 141 is connected to the bottom end of the push rod 142, the movable end of the pressure block 143 is rotatably connected to the top end of the push rod 142, and the middle end of the pressure block 143 is rotatably connected to the base 145 through the connecting rod 144. The cylinder 141 is used to drive the push rod 142 to move up and down so that the pressure block 143 is attached to and pressed against the surface of the base 145 or away from the surface of the base 145; the surface of the base 145 is provided with an optical fiber fixing groove, and the optical fiber fixing groove is used to place and fix the optical fiber to be processed.

[0043] Specifically, the optical fiber fixing groove provided in this embodiment is detachably mounted on the base 145 . Thus, in this embodiment, optical fiber positioning grooves 146 of different specifications can be installed on the base 145 to limit light of different diameters.

[0044] Optional, see Figure 6a and Figure 6b , Figure 6a This is a structural diagram of a fiber optic positioning groove provided by an embodiment of the present invention. Figure 6b FIG. 1 is a structural diagram of the lower surface of the optical fiber positioning groove provided by an embodiment of the present invention, as shown in FIG. Figure 6a and Figure 6b As shown, the lower surface of the optical fiber fixing groove provided in this embodiment can also be provided with an air suction hole, and the air suction hole is connected to the groove of the optical fiber positioning groove 146. The lower part of the base 145 can be provided with a vacuum chamber and an air pipe joint threaded hole, and the vacuum of the vacuum pump is transmitted to the optical fiber positioning groove 146 through the air pipe, so that the optical fiber in the groove of the optical fiber positioning groove 146 can be sucked tightly to prevent it from moving out of the optical fiber positioning groove 146.

[0045] In other embodiments, see Figure 7a and Figure 7b , Figure 7a and Figure 7b 1 is a structural diagram of an optical fiber heating structure provided in an embodiment of the present invention. The optical fiber heating structure 110 provided in this embodiment may include a mounting plate 111, an electromagnet 112, an upper cover 113, a driving pin 114, and a third motor 115; The mounting plate 111 is used to fix the third motor 115. The drive pin 114 is connected to the upper cover 113 via a flat key or a top screw. The driving end of the third motor 115 is connected to the drive pin 114 and is used to drive the drive pin 114 to rotate to complete the opening and closing operation between the upper cover 113 and the mounting plate 111. The electromagnet 112 is arranged between the upper cover 113 and the mounting plate 111 and is used to close the upper cover 113 and the mounting plate 111 via electromagnetic force when the upper cover 113 and the mounting plate 111 are closed. Specifically, the rotation of the third motor 115 can automatically open and close the upper cover 113 by 90-120 degrees, eliminating the need for manual opening and closing of the cover, thereby improving the convenience of fiber stripping.

[0046] In this way, by simultaneously setting the electromagnet 112 and the third motor 115 in the optical fiber heating structure 110, the upper cover 113 can move up and down and rotate in a superimposed manner under the action of the electromagnetic force and the third motor 115, thereby realizing the functions of automatically opening and closing the cover, and closing and stripping the fiber.

[0048] See Figure 8 , Figure 811. The present invention provides a schematic diagram of the position change of the optical fiber to be processed during the fiber stripping process provided by the embodiment of the present invention. In order to better illustrate the working principle of the fiber stripping device 100 provided by the embodiment of the present invention, the following is a detailed description of the method of using the fiber stripping device 100 provided by the present invention: First, the first optical fiber clamping structure 140 and the second optical fiber clamping structure 150 on both sides are automatically opened by the cylinder 141, and the upper cover 113 of the middle optical fiber heating structure 110 is in the open position under the drive of the third motor 115; then, the optical fiber to be processed is placed in the position to be stripped, the first optical fiber clamping structure 140 automatically clamps the optical fiber to be processed, and the upper cover 113 is rotated to a horizontal state under the drive of the third motor 115, and the upper cover 113 is automatically closed downwards under the action of the electromagnetic force of the electromagnet 112. At this time, the optical fiber to be processed is in Figure 8 ; the optical fiber heating structure 110 is turned on to preheat the optical fiber to be processed for a certain period of time, and then the first optical fiber clamp structure 140 moves the required length (L1) in the direction away from the optical fiber heating structure 110 to start stripping. After the end, the vacuum dust removal system starts to clean the blade of the first fiber stripping knife structure 120, and the electromagnet 112 is turned off. At this time, the upper cover 113 automatically bounces up to a certain height under the elastic force of the spring 118, and the first optical fiber clamp structure 140 is opened. At this time, the stripping process of any end of the optical fiber to be processed can be completed, that is, the tail stripping. At this time, the optical fiber to be processed is in Figure 8 The second position is shown in .

[0049] When it is necessary to strip the middle window of the optical fiber to be processed, the optical fiber to be processed can be clamped by the second optical fiber clamp structure 150, and the second optical fiber clamp structure 150 is moved a certain distance (L1+(L-L1-L2)) away from the optical fiber heating structure 110. Figure 8 ; then, under the action of electromagnetic force, the upper cover 113 automatically closes downwards, the optical fiber heating structure 110 starts to preheat the optical fiber to be processed for a certain time, and then the second optical fiber clamp structure 150 moves the required length (L2) in the direction away from the optical fiber heating structure 110 to start fiber stripping. After the end, the vacuum dust removal system starts to clean the blade of the second fiber stripping knife structure 130, and the electromagnet 112 is turned off. The upper cover 113 automatically bounces up to a certain height under the elastic force of the spring 118, and the second optical fiber clamp structure 150 is opened. The upper cover 113 is driven by the third motor 115 to the open position to complete the middle section fiber stripping. The middle section fiber stripping length is L1+L2. At this time, the optical fiber to be processed is in Figure 8 The fourth position shown in .

[0050] Wherein, L is the effective heating length of the hot plate of the middle optical fiber heating structure 110, L1 is the first or tail fiber stripping length (1 to L), L2 is the second fiber stripping length (1 to L), and L1+L2 is the required middle fiber stripping length (2 to 2*L).

[0051] It should be noted that, when performing mid-stripping, a certain overlapping area, for example, 0-3 mm, may be provided between the two stripping openings to ensure that the coating layer is completely stripped off.
