Description

Technical Field

[0001] The utility model relates to the field of optical fiber post-processing auxiliary tooling, in particular to an optical fiber pulling component, an optical fiber length measuring device and an optical fiber auxiliary tube threading device. Background Art

[0002] Optical fiber is an indispensable medium for transmitting optical signals in communication equipment or components. When processing optical fiber communication components (such as optical fiber cables, optical fiber probes, etc.), it is often necessary to guide the optical fiber into a protective sleeve to avoid abnormalities such as external force damage during subsequent applications. In actual production and processing, some manufacturers use manual insertion of optical fibers to insert the optical fiber into the sleeve. Due to the large uncertainty of manual operation, such as insertion force and speed, the performance of the processed optical fiber components will fluctuate. With the increasing performance requirements of downstream demanders for optical fiber components, some literatures have disclosed equipment that can replace manual insertion of optical fibers. There are also some customized optical fiber tube-threading equipment on the market, but most of these auxiliary equipment are expensive, which makes them uneconomical in some small-scale production scenarios. Therefore, it is a very positive and practical research topic to propose an optical fiber traction component that can replace manual optical fiber traction and has a simple structure and low cost.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is particularly noted that the following embodiments are only used to illustrate the present invention, but do not limit the scope of the present invention. Similarly, the following embodiments are only partial embodiments of the present invention rather than all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Combination Figures 1 to 4 As shown in one of the embodiments, this embodiment provides an optical fiber pulling assembly, which includes:

[0032] Support frame 1;

[0033] A driving motor 2 is fixedly mounted on the support frame 1 via a first bracket 21, and the driving motor 2 has a rotating shaft for outputting driving force;

[0034] The driving wheel 3 is fixedly connected to the rotating shaft of the driving motor 2 and driven by the driving motor 2 to rotate;

[0035] A driven wheel 4 is rotatably arranged on the support frame 1 via a second bracket 41, and the outer peripheral side of the driven wheel 4 is opposite to the outer peripheral side of the driving wheel 3;

[0036] The elastic rings 5 ​​are a pair and are fixedly mounted on the outer circumferences of the driving wheel 3 and the driven wheel 4, respectively. The elastic rings 5a and 5b on the outer circumferences of the driving wheel 3 and the driven wheel 4 are in tangential contact with each other. The driving wheel 3 rotates to drive the driven wheel 4 to rotate accordingly. That is, when the driving wheel 3 rotates, friction is generated between the elastic ring 5a mounted on its outer circumference and the elastic ring 5b mounted on the outer circumference of the driven wheel 4, thereby driving the driven wheel 4 to rotate accordingly.

[0037] In this solution, the elastic ring 5 may have a thickness of 3 to 10 mm, a width of 5 to 15 mm, and may be made of rubber or silicone.

[0038] Among them, the contact portion between a pair of the elastic rings 5a and 5b forms a traction part 6 for traction of the optical fiber 10, one side of the traction part 6 is an input side 61, and the other side is an output side 62. The optical fiber 10 penetrates into the traction part 6 from the input side 61 of the traction part 6 and is led out from the output side 62. When the driving wheel 3 rotates, the optical fiber 10 penetrated into the traction part 6 is pushed and moves along the output side 62.

[0039] This solution cleverly sets elastic rings 5a and 5b on the outer peripheral sides of the driving wheel 3 and the driven wheel 4, and utilizes the elastic force of the elastic ring 5 to allow the optical fiber 10 to be introduced into the traction portion 6 between the pair of elastic rings 5a and 5b. A guide channel for traction of the optical fiber 10 can be formed by slight deformation of the pair of elastic rings 5. The optical fiber 10 is pushed to move by the rotation of the driving wheel 3 and the friction between the elastic rings 5a and 5b, thereby achieving a traction effect. This method is not only reliable in implementation, but also simple in structure and low in cost, and is suitable for many processing scenarios that require traction of optical fibers.

[0040] In order to facilitate the control of the drive motor 2, as a possible implementation mode, further, this solution also includes:

[0041] The controller 7 is electrically connected to the driving motor 2 , and the driving motor 2 is controlled by the controller 7 to start and stop.

[0042] In order to conveniently record or control the rotational travel of the driving motor 2, as a preferred implementation option, preferably, the driving motor 2 in this solution can be a servo motor or a servo reduction motor.

[0043] In order to facilitate the length measurement of the pulled optical fiber 10, as a preferred implementation option, preferably, the optical fiber pulling assembly of this solution further includes:

[0044] The wheel encoder 42 is fixed on the second bracket 41 and has a counting shaft. The counting shaft is fixedly connected to the radial center of the driven wheel 4. The driven wheel 4 rotates to drive the counting shaft of the wheel encoder 42 to rotate, so that the wheel encoder counts; wherein the wheel encoder 42 is electrically connected to the controller 7.

[0045] In this solution, when the optical fiber traction assembly has a wheel encoder 42, the wheel encoder 42 can be directly installed on the second bracket 41, and then the driven wheel 4 is connected to the counting shaft of the wheel encoder 42 to achieve the rotational connection of the driven wheel 4; when the wheel encoder 42 is not installed, the driven wheel 4 can also be rotatably connected to the second bracket 41 through a rotating pin or other rotating connecting parts.

[0046] In order to facilitate the pulling of the optical fiber 10, as a preferred implementation option, preferably, the optical fiber pulling assembly of this solution further includes:

[0047] The first guide member 8 is a trumpet-shaped structure, which is arranged on the input side 61 of the traction part 6, and the trumpet-shaped structure of the first guide member 8 faces the traction part 6; the first guide member 8 is also fixedly connected to the support frame 1 through a third bracket 81;

[0048] The second guide member 9 is a trumpet-shaped structure, which is arranged on the output side 61 of the traction part 6, with the large mouth end of the trumpet-shaped structure of the second guide member 9 facing the traction part 6; the second guide member 9 is also fixedly connected to the support frame 1 through a fourth bracket 91.

[0049] This solution cleverly guides the movement of the optical fiber 10 through the first guide member 8 and the second guide member 9 of the trumpet-shaped structure, making it more convenient and simple for the operator to guide the optical fiber 10 into the traction part 6 for the first time; at the same time, the first guide member 8 and the second guide member 9 also provide a certain limit for the subsequent movement of the optical fiber 10, preventing the optical fiber 10 from slipping out of the traction part 6, thereby improving the reliability of the component.

[0050] Based on the above, the optical fiber pulling assembly of the present solution can be used as one of the components in an optical fiber length measuring device to provide convenient assistance for the fixed-length output of the optical fiber 10 .

[0051] In addition, the optical fiber traction assembly of the present invention can also be used as one of the components in an optical fiber auxiliary tube threading device, and the optical fiber auxiliary tube threading device can include at least one of the optical fiber traction assemblies or the optical fiber length measuring device described above; wherein the sleeve of the optical fiber to be threaded is arranged on the output side 62 of the traction part 6.

[0052] The above descriptions are only some embodiments of the present invention, and do not limit the protection scope of the present invention. Any equivalent device or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
