Description

1238097 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a lens optical fiber polishing system and method, and more particularly to a lens optical fiber polishing system. The control unit has a relatively simple structure and a The complete vision basic program is used to precisely grind the lens fiber. [Previous technology] Optical fiber is currently the best optical waveguide, and it has been widely used in daily life 'such as transmitting information such as image, sound and data. Because the optical fiber has the quality of the valley, high quality, and high speed, the optical fiber cable will quickly and gradually replace the communication cable 'and become a new peek into the communication industry. The choice of light source has become one of the indispensable factors for light retransmission. However, the light source sold on the market is very expensive. Therefore, Lens Fiber is studied to save costs and improve technical yield. , And then achieve high popularity and high added value. For example, as shown in FIG. 1, a laser light source generates a source radiation pattern 12 in an optical fiber 14. The optical fiber 14 is composed of a fiber core 16 and a cladding 18, and has a butt end 22 facing the laser light source 10. A fiber acceptance angle (0) is defined between the laser light source (10) and the optical fiber (14), which forms a fan-like area in the radiation pattern (12) of the light source to calculate the coupling efficiency. Ef f iciency). The coupling efficiency is about 8% to 18%. The main reason is that the optical field mode (m 0 d e) of the 5 xuan laser light source 10 and the optical fiber 14 is different, so that the coupling efficiency between the two is limited. Therefore, in the prior art, in order to improve

1238097 V. Description of the invention (2) High coupling efficiency between laser light source and optical fiber, and propose various coupling methods. For example, a bulk optics (not shown) is arranged between the laser light source and the optical fiber to focus the laser beam on the core of the optical fiber so that the modalities between the two can be matched, which is called separation. Type coupling method, its coupling efficiency can reach about 50% -60%. In addition, for example, a microlens or a lens head 32 is formed at the front end of an optical fiber 24, which serves as a mode converter to focus the laser beam on its optical fiber core 26 to make the laser The modalities between the light source 10 and the optical fiber 26 can be matched, which is called an integrated coupling method, as shown in FIG. 2, and the optical fiber 24 is also called a lensed fiber. In the integrated coupling method, the shape of the micro-lens may be a semi-circular lens, a conic lens, a micro-sphere, or a tapered semi-circular lens ( tapered hemispherical) or hyperbolic lens. For example, the coupling efficiency of a lens fiber with a hyperbolic lens head is the highest, which can reach about 90% or more. For most experimental cases, it is important to precisely control the lens tip radius of the lens fiber because it directly affects the coupling efficiency. The conventional fiber lapping system is used to polish the lens head of the lens fiber. However, the conventional lens fiber polishing system has a multi-axis motion control unit, and its structure is usually complicated. Therefore, there is a need to provide a lens fiber polishing system whose control unit has a simpler structure and a basic vision program. [Summary of the Invention]

The iterative grinding operation mode divides the set distance into a plurality of distances, and moves the lens fiber along a linear movement direction M0 and gradually moves according to the plurality of distances to increase the yield of the lens head 108. In step 2 16, the protruding part of the lens fiber 106 lens head 108 is polished into a first chisel surface by the repeated grinding operation mode. In step 2 18, when the first set angle remains unchanged, 'the lens fiber 1 06 is rotated to a third set angle in the rotational movement direction μ 1, and in step 220 _, the lens fiber 1 0 is further rotated. 6 Move to a set distance along the linear motion direction M0.

In step 2 72, the protruding portion of the lens fiber 108 lens head 108 is polished into an inclined surface by the repeated grinding operation mode. In addition, the lens optical fiber 106 can be rotated to an angle along the rotational movement direction M1, and the angle of the inclined surface can be checked by the image detection unit 104, as shown in Figs. 11a and 12b. In step 274, the lens fiber 106 is moved backward in the linear movement direction M0 to the set distance to return to the origin.

Set the angle so that the fiber centerline 5 2 is parallel to the z-axis. Referring again to FIG. 6 'under the user-defined operation mode', as shown in step 2 7 6, such as the operation mode of the four-sided bevel, the calibration procedure of the four-sided bevel is the same as the shape of the flat chisel The calibration procedure is the same for Chisse-shaped operating modes. In step 278, the optical fiber center line 1 5 2 is rotated to a first set angle in the rotational movement direction M 2. In step 280, 'rotate the lens fiber 丨 〇6 in a rotational movement direction M 丨 to a second set angle'. In step 828, move the lens fiber 1 〇6 to a linear movement direction M0. The distance is set, and in step 284, the protruding portion of the lens fiber 〇06 lens head 〇08 is ground into a first chisel surface by the repeated grinding operation mode. When the first set angle remains unchanged, repeat steps 2 0 0, 2 8 2 and 2 8 4 three times, and then grind the protruding part of the lens fiber 丨 〇6 lens head 1 〇8 into a second surface ( Second Chisel Surface), a Second Chisel Surface and a Fourth Chisel Surface. In step 286, when the four-side grinding is completed, the process proceeds to the next step. In addition, the lens optical fiber 106 can be rotated to an angle along the rotation movement direction M1, and the image detection early element 104 can be used to check the distance between the first, first, third, and fourth planes. Angle, as shown in Figures 12a and 12b. In step 288, the lens optical fiber 106 is moved in the linear movement direction M 0 in the reverse direction to the set distance to return to the origin. Finally, in step 290, the tip of the lens optical fiber 106 lens head 108 is restored to the original zero reference position, that is, the centerline of the optical fiber 1 5 2 is rotated in the reverse rotation direction M 2 to the first position.
