Description

Technical Field

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

[0002] Thermal stripping pliers are generally used for removing the coating of small-diameter optical fibers. Existing thermal stripping pliers can generally only strip the tails of pump fibers or signal fibers with relatively small diameters, and there are many burrs and cracks at the stripping openings. Specifically, the existing thermal stripping pliers have the following defects:

[0003] 1. Existing thermal stripping pliers usually adopt a pair of "V"-shaped cutting edges. When the diameter of the optical fiber is relatively large, the distance between the upper and lower knives becomes larger, resulting in only a part of the entire circle of the optical fiber coating being cut, and the remaining uncut part of the optical fiber coating is pulled off passively. Therefore, when using thermal stripping pliers with "V"-shaped cutting edges to remove the coating of optical fibers, there are problems of many burrs and cracks at the stripping opening, and this problem becomes more obvious when the diameter of the optical fiber is larger;

[0004] 2. Existing thermal stripping pliers can generally only strip the coating at one end of the optical fiber and cannot strip the middle section window of the optical fiber, that is, the middle coating of the optical fiber;

[0005] 3. Existing thermal stripping pliers have a single fiber stripping knife structure, and the fiber stripping debris is not automatically cleaned in time, or only blown by compressed air, which cannot ensure the cleanliness of the fiber stripping surface. Therefore, when turning 180° again to strip the other end, the debris may jam the knife or cause more cracks and burrs at the stripping opening.

[0006] 4. Existing thermal stripping pliers only have a single fiber stripping knife structure, and the fiber clamp is manually opened and closed, unable to automatically adjust the position of the required fiber stripping opening, and unable to strip the middle section window of the optical fiber through a single clamping.

[0007] Therefore, there is an urgent need for a new fiber stripping device to solve the technical problems existing in the existing thermal stripping pliers. Summary of the Invention

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] It should be understood that the various steps recorded in the method embodiments of the present disclosure can be executed 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 regard.

[0051] As used herein, the term "including" and its variants are open-ended, that is, "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0052] In the embodiments of the present invention, a thermal stripper is generally used to remove the coating layer of the tail of a small-diameter optical fiber. The existing thermal strippers can only strip the pump fiber or signal fiber with a small diameter, and there are many burrs and cracks at the stripping opening. Specifically, the existing thermal strippers have the following defects:

[0053] 1. The existing thermal strippers usually adopt a pair of "V"-shaped cutting edges. When the diameter of the optical fiber is large, the distance between the upper and lower blades becomes larger, resulting in only a part of the entire circle of the optical fiber coating layer being cut, and the remaining uncut part of the optical fiber coating layer is pulled off passively. Therefore, when using a thermal stripper with a "V"-shaped cutting edge to remove the coating layer of the optical fiber, there are problems of many burrs and easy crack generation at the stripping opening, and this problem is more obvious when the diameter of the optical fiber is larger;

[0054] 2. The existing thermal strippers can generally only strip the coating layer at one end of the optical fiber and cannot strip the middle section window of the optical fiber, that is, the middle coating layer of the optical fiber;

[0055] 3. The existing thermal strippers are of a single fiber stripping knife structure, and the fiber stripping debris is not automatically cleaned in time, or only blown by compressed air, which cannot ensure the cleanliness of the fiber stripping surface. Therefore, when turning 180° to strip the other end again, the debris may get stuck in the knife or cause more cracks and burrs at the stripping opening.

[0056] 4. The existing thermal strippers 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 opening and cannot realize the fiber stripping of the middle section window of the optical fiber through a single clamping.

[0057] Therefore, there is an urgent need for a new fiber stripping device to solve the technical problems existing in the existing thermal stripping pliers.

[0058] To solve the technical problems existing in the related art, an embodiment of the present invention provides a fiber stripping device 100. Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the fiber stripping device provided by the embodiment of the present invention. As Figure 1 shown, the fiber stripping device 100 provided by the embodiment of the present invention includes: a fiber heating structure 110, a first fiber stripping knife structure 120, a second fiber stripping knife structure 130, a first fiber clamping structure 140, and a second fiber clamping structure 150;

[0059] Wherein, the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 are arranged on the fiber heating structure 110 and located at opposite ends of the fiber heating structure 110. The fiber heating structure 110 is used to heat the coating layer of the fiber to be processed. The first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 respectively have circumferential cutting edges for stripping the coating layer of the fiber to be processed. The first fiber clamping structure 140 and the second fiber clamping structure 150 are respectively arranged on the sides of the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 away from the fiber heating structure 110. The first fiber clamping structure 140 and the second fiber clamping structure 150 are respectively used to clamp or release the non-stripping part of the fiber to be processed exposed outside the fiber heating structure 110, and both the first fiber clamping structure 140 and the second fiber clamping structure 150 are used to move on a target path, and the target path is a path on a straight line parallel to the straight line where the axis of the fiber to be stripped is located.

[0060] 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 where the axis of the fiber to be stripped is located, or a path on the straight line where the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 are located, or a path on other straight lines 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 fiber to be processed by the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130, that is, the axis of the fiber to be stripped, is kept in the same straight line as the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130, and no specific limitation is made here.

[0061] In this embodiment, the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 provided in this embodiment operate separately to perform fiber stripping on the opposite ends of the fiber to be processed, so that not only can the tail fiber at any end of the 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 fiber stripping, but also the two ends of the fiber to be processed can 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 mid-section fiber stripping.

[0062] Specifically, in this embodiment, by arranging a set of fiber stripping knife structures at the left and right ends of the fiber heating structure 110 respectively, the fiber stripping knife structures on both sides can share a heating module, thereby effectively improving the fiber stripping efficiency of single-tail fiber stripping and double mid-section fiber stripping.

[0063] In some embodiments, the fiber stripping device 100 provided in this embodiment may further include a driving structure 160. The driving structure 160 is respectively connected to the first fiber clamping structure 140 and the second fiber clamping structure 150 and is used to drive the first fiber clamping structure 140 or the second fiber clamping structure 150 to move on the target path.

[0064] 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;

[0065] Wherein, 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 fiber clamping 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 fiber clamping structure 150. The first motor 161 is connected to the first gear 162, the first rack 163 meshes with the first gear 162, the second motor 165 is connected to the second gear 166, and the second rack 167 meshes with the second gear 166.

[0066] 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 share one 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 two corresponding 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 the 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 positions and limiting directions of the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 for the optical fiber to be processed are the same as those of the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 and are on the same straight line. No specific limitation is made here.

[0067] In this way, by driving the gears to rotate respectively by 2 sets of motors to drive the racks to move in different directions, the fiber clamp structure connected to the ends of the racks can also move accordingly, so that the independent fiber stripping movement left and right can be independently realized.

[0068] In some embodiments, please refer to Figure 2 , Figure 3a , Figure 3b and Figure 4 , Figure 2 is a schematic structural diagram of a fiber stripping knife structure provided by an embodiment of the present invention, Figure 3a is a schematic structural diagram of a first tool holder provided by an embodiment of the present invention, Figure 3b is a schematic structural diagram of a second tool holder provided by an embodiment of the present invention, Figure 4 is a schematic structural diagram of a first blade and a second blade provided by an embodiment of the present invention. Specifically, as Figure 2 , Figure 3a , Figure 3b and Figure 4As shown, both the first fiber stripping knife structure 120 and the second fiber stripping knife structure 130 provided in this embodiment 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 for mounting a first blade 1212, and the second knife seat 122 is provided with a second blade mounting groove 1221 for mounting a second blade 1222. The first knife seat 121 and the second knife seat 122 are spliced and connected in the direction where the openings of the first blade mounting groove 1211 and the second blade mounting groove 1221 face each other, 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 made to fit together to form a circumferential cutting edge for stripping the coating layer of the fiber to be processed.

[0069] Among them, the first blade mounting groove 1211 and the second blade mounting groove 1221 provided in this embodiment can be assembled with blades of different specifications, so as to achieve the purpose of fiber stripping treatment for fibers of different diameters. Specifically, in order to assemble blades of different specifications in the first blade mounting groove 1211 and the second blade mounting groove 1221 and achieve the purpose of fiber stripping treatment for fibers of different diameters, the first knife seat 121 and the second knife seat 122 provided in this embodiment can respectively be provided with first pin holes H1 on the sides of the first blade mounting groove 1211 and the second blade mounting groove 1221. The first blade 1212 and the second blade 1222 can respectively be provided with second pin holes H2. The first pin holes H1 and the second pin holes H2 correspond to each other. The first blade 1212 and the second blade 1222 are respectively fixed in the first blade mounting groove 1211 and the second blade mounting groove 1221 by a fixing pin shaft passing through the corresponding first pin holes H...

[0070] In this way, by providing the second pin holes H2 corresponding to the first pin holes H1 on blades of different specifications, when installing blades of different specifications into the blade mounting grooves, the fixing pin shaft can be passed through the first pin holes H1 on the knife seat and the second pin holes H2 on the blades at the same time, so as to achieve the purpose of fixedly installing blades of different specifications in the blade mounting grooves of the knife seat. Thus, by assembling blades of different specifications in the blade mounting grooves, fiber stripping treatment can be carried out on fibers of different diameters.

[0071] Meanwhile, to achieve stable fiber stripping, a fiber guiding groove 1213 may be provided on the first tool holder 121 provided in this embodiment. A groove 1223 matching the fiber guiding groove 1213 may be provided on the second tool holder 122. The groove 1223 is used to provide a clearance space for the fiber guiding groove 1213, so that the first tool holder 121 and the second tool holder 122 can be tightly spliced and connected.

[0072] Among them, the fiber guiding groove 1213 provided in this embodiment is a V-shaped guiding groove to facilitate the positioning of the fiber to be processed.

[0073] To facilitate the tight splicing and connection of the first tool holder 121 and the second tool holder 122, a positioning pin shaft 1214 may be provided on the first tool holder 121 provided in this embodiment. A positioning pin hole H3 matching the positioning pin shaft 1214 is provided on the second tool holder 122. The first tool holder 121 and the second tool holder 122 are tightly spliced and connected through the cooperation between the positioning pin shaft 1214 and the positioning pin hole H3, so as to effectively ensure the stability of the connection between the first tool holder 121 and the second tool holder 122, and thus achieve the purpose of tightly splicing and connecting the first tool holder 121 and the second tool holder 122.

[0074] In some embodiments, to ensure the cleanliness of the blade surface during the fiber stripping process, the debris generated during the fiber stripping process needs to be cleaned in a timely manner in this embodiment. Specifically, a vacuum pipe interface 1215 may be provided on the first tool holder 121 provided in this embodiment. A first vacuum chamber 1216 is provided between the first blade installation groove 1211 and the fiber guiding groove 1213 on the first tool holder 121. A second vacuum chamber 1224 is provided between the second blade installation groove 1221 and the groove 1223 on the second tool holder 122. The first vacuum chamber 1216 and the second vacuum chamber 1224 are connected to the vacuum pipe interface 1215 to form a vacuum environment when the first tool holder 121 and the second tool holder 122 are spliced and connected. In this way, to avoid the situation that debris may jam the blade or cause an increase in cracks and burrs at the stripping opening, the vacuum dust removal system is connected through the vacuum pipe interface 1215 in this embodiment to clean the debris generated during the fiber stripping process in a timely manner, so as to keep the blade surface clean.

[0075] It should be noted that a vacuum pipe interface 1215 may also be provided on the second tool holder 122 provided in this embodiment. In this embodiment, the vacuum chambers of the first tool holder 121 and the second tool holder 122 can be vacuum adsorbed simultaneously, so as to effectively increase the suction force of the vacuum adsorption during the fiber stripping process and further improve the debris cleaning efficiency.

[0076] Optionally, the first tool holder 121 provided in this embodiment may further be provided with a mounting counterbore H4, so that the first tool holder 121 can be easily assembled to the optical fiber heating structure 110 through the mounting counterbore H4.

[0077] In some embodiments, please refer to Figure 5 , Figure 5 which is a schematic structural diagram of an optical fiber clamping structure provided by an embodiment of the present invention.

[0078] wherein, the cylinder 141 is connected to the bottom end of the push rod 142, the movable end of the pressing block 143 is rotatably connected to the top end of the push rod 142, the middle end of the pressing block 143 is rotatably connected to the base 145 through the connecting rod 144, and the cylinder 141 is used to drive the push rod 142 to move up and down, so that the pressing block 143 fits and presses the surface of the base 145 or moves away from the surface of the base 145; an optical fiber fixing groove is provided on the surface of the base 145, and the optical fiber fixing groove is used to place and fix the optical fiber to be processed.

[0079] Specifically, the optical fiber fixing groove provided in this embodiment is detachably installed on the base 145. In this way, different specifications of optical fiber positioning grooves 146 can be installed on the base 145 in this embodiment to limit optical fibers with different diameters.

[0080] Optionally, please refer to Figure 6a and Figure 6b , Figure 6a which is a schematic structural diagram of an optical fiber positioning groove provided by an embodiment of the present invention, Figure 6b and Figure 6a is a schematic structural diagram of the lower surface of the optical fiber positioning groove provided by an embodiment of the present invention. As Figure 6b shown, an air suction hole may further be opened on the lower surface of the optical fiber fixing groove provided in this embodiment, and the air suction hole communicates with the groove of the optical fiber positioning groove 146. A vacuum cavity and a trachea joint threaded hole may be opened in the lower part of the base 145. The vacuum of the vacuum pump is transmitted to the optical fiber positioning groove 146 through the trachea, so as to suck and tighten the optical fiber in the groove of the optical fiber positioning groove 146 and prevent it from moving and disengaging from the optical fiber positioning groove 146.

[0081] In other embodiments, please refer to Figure 7a and Figure 7b , Figure 7a and Figure 7bIt is a schematic structural diagram of an optical fiber heating structure provided by 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 shaft 114, and a third motor 115;

[0082] Among them, the mounting plate 111 is used to fix the third motor 115. The driving pin shaft 114 is connected to the upper cover 113 through a flat key or a setscrew. The driving end of the third motor 115 is connected to the driving pin shaft 114, and is used to drive the driving pin shaft 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 make the upper cover 113 and the mounting plate 111 close together by 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°, without manual opening and closing of the cover, improving the convenience of fiber stripping processing.

[0083] In this way, by simultaneously arranging 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 superimposed under the action of electromagnetic force and the third motor 115, realizing the functions of automatically opening and closing the cover and closing for fiber stripping.

[0084] Further, please continue to refer to Figure 7a and Figure 7b , the optical fiber heating structure 110 provided in this embodiment may further include a linear slide rail 116, a slider 117, a connecting plate 119, and a spring 118. The linear slide rail 116 is arranged on the outer side of the lower end of the mounting plate 111 and on one side of the driving pin shaft 114. The slider 117 is slidably connected to the linear slide rail 116. The spring 118 is arranged between the slider 117 and the bottom end of the lower end of the mounting plate 111. The connecting plate 119 is connected to the slider 117 by screws. The connecting plate 119 is rotatably connected to the pin shaft 114 through a pin hole. The spring 118 is used to buffer a part of the impact force when the upper cover 113 is closed, and convert the impact force into elastic potential energy for storage. Then, when the electromagnet 112 is turned off and the electromagnetic force disappears, the elastic potential energy is released to bounce up the slider 117 and the connecting plate 119, and then bounce up the pin shaft 114 and the upper cover 113, realizing the automatic bouncing up of the upper cover 113.

[0085] Please refer to Figure 8 , Figure 8It is a schematic diagram of the position change of the optical fiber to be processed during the fiber stripping process provided by an embodiment of the present invention. To better illustrate the working principle of the fiber stripping device 100 provided by the embodiment of the present invention, the following will detail the usage method of the fiber stripping device 100 provided in this embodiment: First, the first fiber clamping structure 140 and the second fiber clamping structure 150 on both sides are automatically opened by the cylinder 141, and the upper cover 113 of the intermediate optical fiber heating structure 110 is in the open position driven by the third motor 115; then, the optical fiber to be processed is placed in the position to be stripped, the first fiber clamping structure 140 automatically clamps the optical fiber to be processed, the upper cover 113 is rotated to the horizontal state driven by the third motor 115, and the upper cover 113 automatically closes downward under the electromagnetic force of the electromagnet 112. At this time, the optical fiber to be processed is in Figure 8 the first position shown in; 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 fiber clamping structure 140 moves a required length (L1) in the direction away from the optical fiber heating structure 110 to start fiber stripping. After completion, 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 pops up a certain height under the elastic force of the spring 118, and the first fiber clamping structure 140 is opened. At this time, the fiber stripping process of any end of the optical fiber to be processed can be completed, that is, the tail fiber stripping. At this time, the optical fiber to be processed is in Figure 8 the second position shown in.

[0086] When it is necessary to strip the middle section window of the optical fiber to be processed, the second fiber clamping structure 150 can clamp the optical fiber to be processed and move the second fiber clamping structure 150 a certain distance (L1+(L-L1-L2)) in the direction away from the optical fiber heating structure 110. At this time, the optical fiber to be processed is in Figure 8 the third position shown in; then, the upper cover 113 automatically closes downward under the electromagnetic force, the optical fiber heating structure 110 starts to preheat the optical fiber to be processed for a certain period of time, and then the second fiber clamping structure 150 moves a required length (L2) in the direction away from the optical fiber heating structure 110 to start fiber stripping. After completion, 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 pops up a certain height under the elastic force of the spring 118, and the second fiber clamping structure 150 is opened. The upper cover 113 is rotated to the open position driven by the third motor 115 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.

[0087] Among them, L is the effective heating length of the hot plate of the intermediate optical fiber heating structure 110, L1 is the first or tail fiber stripping length (1~L), L2 is the second fiber stripping length (1~L), and L1+L2 is the required middle section fiber stripping length (2~2*L).

[0088] It should be noted that when stripping the optical fiber in the middle section, a certain overlapping area, such as 0 - 3 mm, can be set between the two stripping ports to ensure that the coating layer is completely stripped.

[0089] Thus, the description of the optical fiber stripping device 100 provided in this embodiment is completed.
