Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber glue dispensing, and in particular relates to an optical fiber positioning glue dispensing device. Background Art

[0002] At present, the general method of gluing optical fiber to the end cap assembly includes the following steps: first, the optical fiber is fused to the end cap, and then the end cap with the fused optical fiber is placed into the end cap assembly, and then the lateral position of the optical fiber in the end cap assembly is manually adjusted, and finally, the optical fiber is fixed by gluing in the end cap assembly.

[0003] In the above process, the lateral position of the optical fiber in the end cap assembly is generally adjusted by fixing it with tape, which makes it impossible to maintain a constant and quantitative tension between the optical fiber and the end cap assembly, making it difficult to unify the process positions of different optical fibers, and there is a defect of unstable tension, which results in a high rate of inferior products for the optical fibers on the production line due to poor glue dispensing quality. Utility Model Content

[0004] In order to solve the above technical problems, the utility model discloses an optical fiber positioning and dispensing device, which can maintain internal stress stability when the optical fiber is dispensing and fixed, thereby ensuring a relatively consistent bonding effect for different optical fibers, thereby preventing the internal refractive index of the optical fiber from being non-uniform due to uneven stress, thereby improving the manufacturing yield of the production line.

[0005] The specific technical solution of the utility model is as follows:

[0006] An optical fiber positioning glue dispensing device, comprising:

[0007] Base;

[0008] An end cap fixing frame is used to place an end cap assembly fused with an optical fiber, and the end cap fixing frame is connected to the base;

[0009] An optical fiber clamp, used for clamping an optical fiber, wherein the optical fiber clamp and a base are movably connected; and

[0010] The dynamometer is arranged on the base and is located at one end of the end cap fixing frame away from the optical fiber clamp, and the dynamometer is connected to the end cap fixing frame.

[0011] The optical fiber is first fused to the end cap assembly, and then the end cap assembly is set on the end cap fixing frame, whereby the optical fiber is straightened between the end cap fixing frame and the optical fiber clamp. At this time, the force gauge has a tension reading, and the staff can use the tension reading to maintain consistent internal force of the optical fiber on the production line, thereby ensuring that the optical fiber dispensing has a high yield rate.

[0012] Preferably, the end cap fixing frame and / or the dynamometer are slidably connected to the base.

[0013] By sliding the end cap fixing frame and / or the dynamometer on the base, the position adjustment can be well achieved, thereby conveniently adjusting the tension reading of the dynamometer to an appropriate value or an appropriate area.

[0014] Preferably, it also includes:

[0015] Slide 1, wherein the slide 1 and the base are movably connected;

[0016] Wherein, the end cap fixing frame and the dynamometer are both arranged on the slide table one.

[0017] The dynamometer can be pre-connected to the end cap fixing frame. After the end cap assembly is placed on the end cap fixing frame, the slide can be driven to slide at the same time. This can ensure the consistency of the internal force of the optical fiber while ensuring the consistency of the dynamometer connection. This can better maintain the internal force of the optical fiber in the production line and avoid inaccurate force measurement data caused by inconsistency of the sliding dynamometer and / or the end cap fixing frame.

[0018] Preferably, the end cap fixing frame and / or the dynamometer are slidably connected to the slide table.

[0019] On the basis that slide one has the sliding ability, the end cap fixing frame and / or the force gauge can slide on slide one, so it has high adjustability, so that the position can be quickly adjusted according to actual conditions before and after the installation of the end cap assembly, and after determining the relative positions of the end cap fixing frame and the force gauge on slide one, the consistency of the internal force measurement of the optical fiber on the production line is ensured.

[0020] Preferably, the end cap fixing frame and the dynamometer are both slidably connected to the base, and a sliding path of the end cap fixing frame on the base is consistent with a sliding path of the base on the end cap fixing frame.

[0021] Keeping the sliding paths of the end cap holder and the force gauge consistent can reduce position adjustment errors, thereby ensuring the yield rate of optical fibers on the production line.

[0022] Preferably, the end cap fixing frame and the dynamometer are both slidably connected to the slide table via a slide groove and slider structure.

[0023] The structure is simple, easy to process and manufacture, and can well meet sliding requirements.

[0024] Preferably, the slide groove in the slide groove slider structure is a T-shaped groove or an inverted T-shaped groove.

[0025] This structure can provide good support for the end cap fixing frame and the dynamometer on the basis of achieving a sliding effect, thereby ensuring sliding stability and, after positioning, ensuring position stability, thereby improving the accuracy of the measured values.

[0026] Preferably, at least one end of the slide slot in the slide slot slider structure is an open end.

[0027] This structure can conveniently install the end cap fixing frame and the dynamometer on the slide table.

[0028] Preferably, a three-axis platform is provided between the optical fiber clamp and the base, and the three-axis platform and the base are slidably connected.

[0029] The three-axis platform can carry the optical fiber clamp to achieve multi-directional translation, thereby better meeting the force measurement requirements of the dynamometer.

[0030] Preferably, it also includes:

[0031] Slide 2, the slide 2 is slidably connected to the base;

[0032] Wherein, the three-axis platform is arranged on the second slide.

[0033] The three-axis platform slides with the base through the slide table 2, so that the relative position between the three-axis platform and the base can be adjusted according to actual needs. Based on this, the three-axis platform can better achieve fine adjustment and realize a lower cost and better effect injection process.

[0034] Compared with the prior art, the utility model does not need to repeatedly adjust the position of the optical fiber, and improves production efficiency and ensures product yield on the basis of achieving coarse adjustment and fine adjustment. In addition, the utility model has a simple structure, is easy to use and maintain, and can reduce quality risks on the basis of ensuring that the optical fiber on the production line has a constant internal force.

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0039] like Figure 1As shown, an optical fiber positioning and dispensing device includes a base 1, an end cap fixing frame 2, an optical fiber clamp 3 and a dynamometer 4; the end cap fixing frame 2 is used to place an end cap assembly fused with an optical fiber 5, and the end cap fixing frame 2 is connected to the base 1; the optical fiber clamp 3 is used to clamp the optical fiber 5, and the optical fiber clamp 3 and the base 1 are movably connected; the dynamometer 4 is arranged on the base 1, located at one end of the end cap fixing frame 2 away from the optical fiber clamp 3, and the dynamometer 4 is connected to the end cap fixing frame 2.

[0040] In this embodiment, the base 1 is provided with a dynamometer 4, an end cap fixing frame 2 and an optical fiber clamp 3 in sequence; the dynamometer 4 is connected to the end cap fixing frame 2, so as to measure the tensile force generated at the melting point between the optical fiber 5 and the end cap fixing frame 2 when the end cap assembly is mounted on the end cap fixing frame 2 and the optical fiber 5 is clamped on the optical fiber clamp 3. After the end cap assembly and the optical fiber 5 are both set on the dispensing device, the optical fiber clamp 3 can be slid to locate its position according to the numerical value of the dynamometer 4, so that the position of the optical fiber clamp 3 is numerically located when dispensing each product on the production line, and the internal force consistency requirement of the optical fiber 5 on the production line can be achieved by fine-tuning the position of the optical fiber clamp 3, so that the product dispensing has a higher yield rate.

[0041] In the present embodiment, the end cap fixing frame 2 and / or the dynamometer 4 are slidably connected to the base 1. Specifically, the end cap fixing frame 2 and the dynamometer 4 are both slidably connected to the base 1. The end cap fixing frame 2 and the dynamometer 4 are connected, so it is necessary to ensure that the relative position between the two is constant, and the position can be adjusted more according to the actual situation, so that when both can slide relative to the base 1, they can be adjusted forward and backward according to the actual situation, thereby expanding the adjustment range. Further, it also includes a slide 6, and the slide 6 and the base 1 are movably connected; the end cap fixing frame 2 and the dynamometer 4 are both arranged on the slide 6. Specifically, the end cap fixing frame 2 and / or the dynamometer 4 are slidably connected to the slide 6. In the present embodiment, the end cap fixing frame 2 and the dynamometer 4 are both slidably connected to the base 1, and the sliding path of the end cap fixing frame 2 on the base 1 is consistent with the sliding path of the base 1 on the end cap fixing frame 2. That is to say, in this embodiment, since the base 1 is connected to the slide 6, when the end cap fixing frame 2 and the dynamometer 4 are both slidably connected to the base 1, it is also equivalent to that the end cap fixing frame 2 and the dynamometer 4 are slidably connected to the slide 6. Further, the end cap fixing frame 2 and the dynamometer 4 are both slidably connected to the slide 6 through the slideway slider 7 structure. In this embodiment, the end cap fixing frame 2 and the dynamometer 4 both have a slider 7, and the slide 6 is arranged in the slideway matched by the slider 7, thereby realizing sliding guidance through the slideway slider 7 structure. The slideway is a T-shaped groove or an inverted T-shaped groove. Specifically, in this embodiment, the slideway in the slideway slider structure is an inverted T-shaped groove, which includes a transverse groove and a longitudinal groove that are interconnected. Therefore, under the premise that the slider 7 cooperates with the slideway, the slider 7 includes a transverse block and a longitudinal block, and the contact area between the end cap fixing frame 2 or the dynamometer 4 and the slide 6 can be increased through the transverse block, thereby achieving effective support on the basis of satisfying the sliding fit, thereby better satisfying the use stability of the dispensing device.

[0042] In this embodiment, at least one end of the slideway in the slideway slider structure is an open end 8. The end cap fixing frame 2 and the dynamometer 4 can slide into the slideway from the open end 8, thereby better meeting the assembly requirements before use.

[0043] In this embodiment, a three-axis platform 9 is provided between the optical fiber clamp 3 and the base 1, and the three-axis platform 9 is slidably connected to the base 1. Further, a second slide 10 is provided, and the second slide 10 is slidably connected to the base 1; the three-axis platform 9 is provided on the second slide 10.

[0044] Therefore, when using the present embodiment, the dynamometer 4 is connected to the end cap fixing bracket 2, and then the dynamometer 4 and the end cap fixing bracket are mounted on the slide 1 6. After adjustment, the relative position of the dynamometer 4 and the slide 1 6 is fixed, and the end cap fixing bracket 2 can slide freely in the slide groove. Then the slide 1 6 is connected to the base 1, and after adjustment, the relative position between the slide 1 6 and the base 1 is fixed. Then the three-axis platform 9 is mounted on the slide 2 10, and the slide 2 10 can slide relative to the base 1.

[0045] The optical fiber 5 and the end cap assembly are placed into the optical fiber clamp 3 and the end cap fixing frame 2 , and the position of the optical fiber 5 in the end cap assembly can be adjusted by adjusting the three-axis platform 9 .

[0046] Furthermore, during use, the optical fiber 5 is fixed in the optical fiber clamp 3, and the three-axis platform 9 is adjusted so that the optical fiber 5 is located exactly in the middle of the end cap assembly. Then, the slide 10 is moved away from the end cap assembly until the digital display value of the dynamometer 4 is close to the predetermined value. Then, the three-axis platform 9 is fine-tuned to keep the tension of the optical fiber 5 near the predetermined value. Finally, glue is dripped into the end cap assembly for curing.

[0047] This method is simple and easy to implement, and can achieve fine adjustment of the position of the optical fiber 5. It has the advantages of low cost and good effect, and can accurately measure the tension of the optical fiber 5 before dispensing, ensuring that the tension of the optical fiber 5 is constant when dispensing glue in each production batch. In other words, it helps to maintain the internal stress of the product, reduce quality risks, and effectively prevent uneven stress from causing different refractive indices inside the optical fiber 5, which may cause heating problems and edge problems in some products.

[0048] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
