The embodiment of the application provides an optical fiber etching device. The following will describe in detail.
Fig. 1 is a schematic structural diagram of an embodiment of an optical fiber etching apparatus according to an embodiment of the present application. As shown in fig. 1, the optical fiber etching device 100 includes a base (not shown), a clamping assembly 110, and an etching assembly (not shown), wherein the clamping assembly 110 includes two clamping members 111 disposed on the base at intervals along a first direction X, and the two clamping members 111 are respectively used for clamping the optical fiber 200 to position the optical fiber 200. The etching component is used to etch the surface of the optical fiber 200 to form a bonding surface or other structure on the surface of the optical fiber 200.
The etching component comprises a laser and a moving mechanism, wherein the laser is used for generating laser, and the moving mechanism is connected with the laser and used for driving the laser to move so that the laser etches the optical fiber 200 along the length direction of the optical fiber 200.
Specifically, the moving mechanism is used for driving the laser to move along the length direction of the optical fiber 200, the laser comprises a galvanometer component positioned on the optical path of the laser, the galvanometer component is used for converting the laser into scanning laser, and the scanning direction of the scanning laser forms an included angle with the length direction of the optical fiber 200. That is, the laser light generated by the laser is moved along the longitudinal direction of the optical fiber 200 and is also oscillated in a direction forming an angle with the longitudinal direction of the optical fiber 200.
Alternatively, the moving mechanism may be used to drive the laser to move along the length direction of the optical fiber 200, and drive the laser to move or swing in a direction forming an angle in the length direction of the optical fiber 200, so that the laser beam of the laser etches the optical fiber 200 along the length direction of the optical fiber 200.
Of course, the laser beam of the laser may be irradiated onto the optical fiber 200, and the moving mechanism is used to drive the laser to move along the length direction of the optical fiber 200, so that the laser beam of the laser etches the optical fiber 200 along the length direction of the optical fiber 200.
In some embodiments, the optical fiber etching apparatus 100 further includes a tension measuring member (not shown in the drawings) for measuring the tension to which the optical fiber 200 is subjected. Therefore, before the optical fiber 200 is etched by the optical fiber etching device 100, the optical fiber 200 can be clamped by the clamping component 110 and the tension applied to the optical fiber 200 can be adjusted, then the tension applied to the optical fiber 200 is measured by the tension measuring component, when the tension applied to the optical fiber 200 is within a preset tension range, the optical fiber 200 is straightened, and then the optical fiber 200 is etched by the etching component, so that the optical fiber 200 is kept in a straight state in the etching process of the optical fiber 200, the etching precision of the etching component to the optical fiber 200 is improved, and then a bonding surface with higher precision is formed on the surface of the optical fiber 200.
In some embodiments, at least one clamping member 111 is slidably coupled to the base along the first direction X, and a tension measuring member is provided to the base and coupled to the clamping member 111 slidably provided to the base to detect tension applied to the clamping member 111.
It will be appreciated that by slidably connecting the clamping member 111 to the base in the first direction X and connecting the tension measuring member to the clamping member 111, the tension applied to the optical fiber 200 is fed back to the tension measuring member via the clamping member 111 slidably connected to the base, thereby measuring the tension applied to the optical fiber 200.
Of course, the tension measuring member may be disposed between the optical fiber 200 and the clamping member 111, and then the tension measuring member is directly connected to the optical fiber 200, and when the optical fiber 200 is subjected to tension, the tension measuring member can directly detect the tension applied to the optical fiber 200.
In the embodiment of the present application, the two clamping members 111 may be slidably connected to the base in the first direction X, or only one of the clamping members 111 may be slidably connected to the base in the first direction X. When the two clamping members 111 are slidably connected with the base along the first direction X, the optical fiber etching device 100 may include two tension measuring members, which are respectively disposed on the base and are connected with the two clamping members 111 in a one-to-one correspondence manner, or the optical fiber etching device 100 may also include one tension measuring member, which is connected with one of the clamping members 111. Of course, the former can further accurately detect the magnitude of the pulling force applied to the optical fiber 200.
As shown in fig. 1, the clamping member 111 includes a connection seat 1111 provided on the base, and a clamping member 1113 movably connected to the connection seat 1111, the clamping member 1113 having a clamping position (as shown in fig. 1) and a releasing position, when the clamping member 1113 is in the clamping position, a clamping space 1115 for clamping the optical fiber 200 is formed between the clamping member 1113 and the connection seat 1111, and when the clamping member 1113 is in the releasing position, the optical fiber 200 is released.
In some embodiments, the clamping spaces 1115 of the two clamping members 111 each extend in the first direction X. Thereby, the portion of the optical fiber 200 clamped between the two clamping members 111 can be made more straight. Specifically, a side of the clamping member 1113 facing the connection base 1111 is provided with a first recess 1114, and the first recess 1114 penetrates the clamping member 1113 along the first direction X. The side of the connecting seat 1111 facing the clamping member 1113 is provided with a second groove 1112, and the second groove 1112 penetrates the connecting seat 1111 along the first direction X. When the clamping member 1113 is in the clamping position, the first recess 1114 of the clamping member 1113 and the second recess 1112 of the connection base 1111 enclose to form a clamping space 1115. In the first direction X, the clamping spaces 1115 of the two clamping members 111 overlap.
In some embodiments, the connection seat 1111 of the clamping member 111 may be slidably connected to the base in the first direction X, such that the clamping member 111 is slidably connected to the base in the first direction X. The tension measuring member may be connected to the connection seat 1111 of the clamping member 111 or the clamping member 1113 of the clamping member 111, so long as the tension applied to the optical fiber 200 can be detected.
In some embodiments, the optical fiber etching apparatus 100 further includes a torsion measuring member (not shown in the drawings) for measuring the torsion force to which the optical fiber 200 is subjected.
It will be appreciated that if there is a twisting of the optical fiber 200 when the clamping assembly 110 clamps the optical fiber 200, when the optical fiber 200 is removed from the clamping assembly 110 after being etched by the etching assembly, the optical fiber 200 automatically returns to the non-twisted state, and at this time, the bonding surface or other structure etched on the surface of the optical fiber 200 is twisted, thereby affecting the accuracy of the bonding surface or other structure of the optical fiber 200.
According to the optical fiber etching device 100 provided by the embodiment of the application, the torsion force of the optical fiber 200 is measured through the torsion measuring component, before the optical fiber 200 is etched through the optical fiber etching device 100, the optical fiber 200 can be clamped through the clamping component 110 and the torsion force of the optical fiber 200 is adjusted, then the torsion force of the optical fiber 200 is measured through the tension measuring component, when the torsion force of the optical fiber 200 is within a preset torsion range value, the optical fiber 200 is straightened, and then the optical fiber 200 is etched through the etching component, so that the optical fiber 200 is kept in a straight state in the process of ensuring the optical fiber 200 to be etched, the etching precision of the etching component to the optical fiber 200 is improved, and then a bonding surface or other structures with higher precision are formed on the surface of the optical fiber 200.
In some embodiments, the torsion measurement component includes a torsion sensor disposed on a side of the clamp 1113 or the connection hub 1111 facing the clamp space 1115. Thus, when the clamping member 1113 and the connection seat 1111 clamp the optical fiber 200, the torsion sensor can directly detect the torsion force received by the optical fiber 200. Of course, the torsion measuring member may measure the torsion applied to the optical fiber 200 in other manners, and only the torsion applied to the optical fiber 200 needs to be accurately measured.
In some embodiments, as shown in fig. 1 to 3, the optical fiber etching device 100 further includes a positioning member 112, where the positioning member 112 is disposed between the two clamping members 111 of the clamping assembly 110 and abuts against a portion of the optical fiber 200 between the two clamping members 111 to position the portion of the optical fiber 200 between the two clamping members 111, so that the portion of the optical fiber 200 between the two clamping members 111 is kept in a more straight state, so as to further improve the etching accuracy of the optical fiber etching device 100 on the optical fiber 200.
Wherein, the positioning member 112 includes a positioning groove 1121, the positioning groove 1121 extends along the first direction X and penetrates the positioning member 112, the positioning groove 1121 is used for accommodating the optical fiber 200, and an inner surface of the positioning groove 1121 is used for abutting against an outer circumferential surface of the optical fiber 200 so as to position the optical fiber 200, so that the optical fiber 200 maintains a straight state. The optical fiber 200 is prevented from being deformed or completely deformed due to vibration in the process of laser etching the optical fiber 200, so that the etching accuracy of the optical fiber 200 is prevented from being affected.
In some embodiments, as shown in fig. 2 and 3, an adsorption hole 1122 is formed in the inner surface of the positioning groove 1121 of the positioning member 112, and the adsorption hole 1122 communicates with an air suction member (not shown). When the optical fiber 200 is placed in the positioning groove 1121 of the positioning member 112, the suction member applies a negative pressure to the suction hole 1122, so that the suction hole 1122 sucks the optical fiber 200 on the inner surface of the positioning groove 1121, thereby further improving the positioning effect of the positioning groove 1121 of the positioning member 112 on the optical fiber 200 and improving the processing accuracy of the optical fiber 200.
The number of the adsorption holes 1122 is plural, and the adsorption holes 1122 are sequentially spaced apart along the first direction X to further improve the adsorption effect on the optical fiber 200.
Specifically, as shown in fig. 3, the positioning member 112 is provided with a cavity 1123 extending in the first direction X, first ends of the plurality of suction holes 1122 communicate with the positioning groove 1121, and the other ends of the plurality of suction holes 1122 communicate with the cavity 1123. The outer surface of the positioning member 112 is provided with a connector 1124 in a protruding manner, which is in communication with the cavity 1123, and the connector 1124 is used to communicate with the air suction member, so that the plurality of suction holes 1122 are in communication with the air suction member. The connecting head 1124 protrudes from a surface of the positioning member 112 along the first direction X.
In some embodiments, the optical fiber etching device 100 further includes a gas pressure sensor (not shown) in communication with the adsorption hole 1122 to detect the gas pressure in the adsorption hole 1122. It can be understood that after the optical fiber 200 is placed in the positioning groove 1121 of the positioning member 112, the air pressure in the suction hole 1122 is detected by the air pressure sensor, and it can be confirmed whether or not the suction hole 1122 sucks the optical fiber 200 in the positioning groove 1121 of the positioning member 112. Further, in the process of etching the optical fiber 200 by laser, it can be determined whether or not the optical fiber 200 is deformed by detecting the air pressure in the suction hole 1122.
The air pressure sensor may be connected to the connector 1124 on the positioning member 112, so as to indirectly detect the air pressure in the adsorption hole 1122 by detecting the air pressure in the cavity. Alternatively, the air pressure sensor may be provided in the chamber to directly detect the air pressure in the chamber, thereby indirectly detecting the air pressure in the adsorption hole 1122.
In some embodiments, the positioning member 112 is made of a metal material. The laser comprises a carbon dioxide laser. Because the absorption rate of the laser generated by the metal to the carbon dioxide laser is very low, the problem that the temperature of the positioning piece 112 is increased or even damaged due to the fact that the positioning piece 112 absorbs excessive laser when the optical fiber 200 is etched by the laser of the laser can be avoided by making the positioning piece 112 made of a metal material.
In some embodiments, the laser may be opposed to the notch of the positioning slot 1121. Alternatively, the laser may be located on one side of the positioning member 112. The laser generated by the laser can etch away the portion of the optical fiber 200 extending out of the notch of the positioning slot 1121, while the portion of the optical fiber 200 located in the positioning slot 1121 remains, so as to further improve the etching accuracy of the laser on the optical fiber 200.
