[0002] As the core component of multi-core fiber optic connectors, MT ferrules are widely used in the optical communications field due to their high throughput and high fiber wiring density. The position, diameter, and opening angle of the fiber holes in the MT ferrule significantly impact the performance of multi-core fiber optic connectors.
[0003] MT ferrules are manufactured through injection molding. The mold typically consists of an upper and lower mold, a ferrule block, a core pin, a guide pin, and a pin holder. The core pin forms the fiber hole in the MT ferrule, so its dimensional accuracy, roundness, and smoothness are crucial factors in determining MT ferrule performance.
[0004] At present, in the processing of core pins, due to the limitation of processing equipment, multiple clamping and grinding are required to realize the processing of different sized structures of different sections of the core pins. However, this is not conducive to further improving the dimensional accuracy, roundness and smoothness of the core pins, affecting the processing quality and hindering the development of fine miniaturization of MT ferrules.

That is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.
[0027] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0028] like Figure 1-2 As shown, the core pin processing device of an embodiment of the present invention includes a core pin 1 used to form the optical fiber hole of an MT ferrule during injection molding. The processing device includes a base 2, a first guide rail 3, a grinding unit 4, a second guide rail 5, and a core pin fixture 6. The base 2 allows the first guide rail 3 and the second guide rail 5 to be mounted on the same horizontal plane.
[0029] The first guide rail 3 is installed on the base 2 and is fixed by bolts. The first guide rail 3 extends along the width direction x of the base 2 .
[0030] The grinding unit 4 includes a motor 41 and a grinding wheel 42. The motor 41 is mounted on the first guide rail 3 and is configured to reciprocate on the first guide rail 3. The rotating shaft 43 of the motor 41 is in transmission connection with the grinding wheel 42. The motor 41 can drive the grinding wheel 42 to rotate via the rotating shaft 43, allowing the grinding wheel 42 to perform the grinding function.
[0031] The second guide rail 5 is installed on the base 2 and is fixed by bolts. The second guide rail 5 extends along the length direction y of the base 2 .
[0032] The core needle jig 6 is mounted on the second guide rail 5 and is configured to reciprocate on the second guide rail 5 . The core needle jig 6 is used to mount the core needle 1 , which extends along the length direction y of the base 2 .
[0033] In this embodiment, the grinding wheel 42 is used to grind the surface of the core needle 1. The grinding wheel 42 can reciprocate on the first guide rail 3, and the core needle 1 can reciprocate on the second guide rail 5. Because the first guide rail 3 extends along the width direction x of the base 2 and the second guide rail 5 extends along the length direction y of the base 2, the relative position of the grinding wheel 42 and the core needle 1 can be adjusted along the width direction x and the length direction y of the base 2. After a single clamping, core needles 1 of different sizes can be processed, which is conducive to ensuring processing accuracy.
[0034] In some embodiments, the base 2 includes a first end surface and a second end surface disposed opposite each other along the length direction y of the base 2. The first guide rail 3 is mounted on the first end surface, and the second guide rail 5 is mounted on the second end surface. Sufficient space is provided between the first guide rail 3 and the second guide rail 5 to adjust the distance between the grinding wheel 42 and the core needle 1.
[0035] In some embodiments, the first guide rail 3 and the second guide rail 5 are both linear guide rails. Exemplarily, the linear guide rail includes a slide rail, a slider slidably mounted on the slide rail, and an electric lead screw for driving the slider to reciprocate on the slide rail. Specifically, the motor 41 and the core needle fixture 6 are both mounted on the slider.
[0036] In some embodiments, the core needle fixture 6 includes a bearing seat 61 and a mounting block 62. The mounting block 62 is rotatably mounted in the bearing seat 61. The mounting block 62 has a mounting hole 64 extending along the length direction y of the base 2. The core needle 1 is mounted in the mounting hole 64. The above structure enables the core needle 1 to rotate in the bearing seat 61, so that the grinding wheel 42 can grind the surface of the core needle 1 360 degrees.
[0037] In some embodiments, the core needle fixture further includes a mounting sleeve 63, which is disposed around the outer periphery of the core needle 1. The core needle 1 is mounted in a mounting hole 64 through the mounting sleeve 63. The end of the mounting sleeve 63 proximal to the grinding wheel 42 extends out of the mounting hole 64. The mounting sleeve 63 is used to protect the core needle 1 and ensure structural stability after the core needle 1 is clamped.
[0038] In some embodiments, the axis of the grinding wheel 42 and the axis of the core needle 1 are on the same horizontal plane. During processing, the grinding surface of the grinding wheel 42 can be aligned with the surface of the core needle 1 to maintain the accuracy of the grinding process.
[0039] In some embodiments, the first guide rail 3 is used to adjust the distance between the grinding wheel 42 and the core needle 1 along the width direction x of the base 2 .
[0040] In some embodiments, the second guide rail 5 is used to adjust the distance between the grinding wheel 42 and the core needle 1 along the length direction y of the base 2 .
[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
