Description

Technical Field

[0001] This utility model relates to the field of optical fiber fixing device technology, and in particular to an optical fiber processing and fixing device. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic that serves as a means of transmitting light. In the field of optical fiber communication, optical fibers are used to connect multiple electronic terminals, and the precision of their manufacturing directly determines the transmission efficiency and accuracy of the optical signal.

[0003] Currently, fiber optic processing and fixing devices mainly consist of two fixing blocks and a support plate. The two fixing blocks are distributed opposite each other on both sides of the support plate, and each block has a core hole that passes through both sides. The optical fiber passes through the two core holes in sequence and is placed on the support plate. With the constraint of the two core holes, it is convenient for laser equipment to process the optical fiber on the support plate. However, the diameter of the core holes is fixed, which can only process optical fibers of fixed size and cannot meet the needs of processing multi-size optical fibers. In addition, fiber processing may cause shape changes (such as becoming S-shaped or U-shaped). Since the two ends of the optical fiber are still inserted into the two core holes, the processed optical fiber is not easy to remove, which affects the processing of subsequent optical fibers.

[0004] Therefore, how to design a fiber optic processing and fixing device that is simple in structure, low in cost, secure in clamping, easy to assemble and disassemble, and adaptable to multiple sizes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This invention provides a fiber optic processing and fixing device, which solves the technical problems of existing fiber optic processing and fixing devices having limited processing dimensions and being difficult to remove.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an optical fiber processing and fixing device, comprising: a base plate, a top plate, and a clamp.

[0007] The top surface of the base plate is provided with a receiving groove, and an LED light can be placed in the receiving groove; the top plate is detachably connected to the base plate and is provided with a light-transmitting hole opposite to the receiving groove. A cavity is provided inside the top plate corresponding to the periphery of the light-transmitting hole, and multiple arrayed vacuum adsorption holes, all communicating with the cavity, are provided on the top surface corresponding to the periphery of the light-transmitting hole. Vacuum vent holes communicating with the cavity are provided on the side surface of the top plate, and support plates are fixed to the opposite two sides of the top plate; the clamp includes two clamping blocks and two pressing blocks. The two clamping blocks are detachably connected to the two support plates by bolts, and each clamping block has a fiber optic groove penetrating both sides on its top surface. The two fiber optic grooves are arranged from away from the top plate to close to the top plate; the two pressing blocks are respectively placed on the top surface of the two clamping blocks corresponding to the openings of the fiber optic grooves and can press against the fiber optics in the corresponding fiber optic grooves, so as to process fiber optics of different diameters at the light-transmitting hole.

[0008] The beneficial effects of this utility model are: it improves the traditional optical fiber processing and fixing structure. First, the optical fiber is slid in the optical fiber groove of the two clamping blocks, and then the pressure block is pressed against the optical fiber in the two optical fiber grooves. It can clamp optical fibers of different diameters on the two optical fiber grooves, which makes it easier for laser equipment to stably process optical fibers at the light transmission hole, improve the processing accuracy of optical fibers, and improve the optical signal transmission efficiency and transmission accuracy.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, both sides of the base plate are provided with heat dissipation holes that communicate with the receiving groove.

[0011] The further beneficial effect of adopting the above is that by opening heat dissipation holes on both sides of the base plate that communicate with the receiving groove, it is not only convenient to dissipate the heat generated by the LED lamp, but also convenient to lay the LED lamp power connection cable.

[0012] Furthermore, the longitudinal cross-section of both optical fiber grooves is a "V" shaped structure.

[0013] Furthermore, both clamping blocks and both pressing blocks have opposite magnetic properties.

[0014] The further beneficial effect of adopting the above is that the magnetic attraction between the clamping block and the pressure block can increase the pressing force of the pressure block on the optical fiber, thereby improving the stability of optical fiber clamping.

[0015] Furthermore, the two support plates are provided with a plurality of threaded holes spaced apart from the top plate to the top plate, and the two clamping blocks are provided with elongated holes arranged from the top plate to the top plate. The two elongated holes are respectively arranged opposite to the plurality of threaded holes on the two support plates; the two bolts respectively pass through the two elongated holes and extend into the corresponding threaded holes.

[0016] The further beneficial effect of adopting the above is that by using bolts to pass through the long strip hole and connect to the corresponding threaded hole, the connection position of the clamping block on the support plate can be changed, which is convenient for clamping optical fibers of different lengths.

[0017] Furthermore, it also includes a light-transmitting carrier sheet, and the top surface of the top plate is provided with a limiting groove; the light-transmitting hole and the vacuum adsorption hole are both located in the limiting groove; the light-transmitting carrier sheet is placed in the limiting groove and presses against the optical fiber that slides through the light-transmitting hole and the plurality of vacuum adsorption holes.

[0018] Furthermore, the flatness of the top surface of the top plate is 3-5 μm. Attached Figure Description
