Abstract
Description
Technical Field
[0001] This utility model relates to the field of optoelectronic device manufacturing technology, specifically to an optoelectronic device positioning fixture. Background Technology
[0002] In the fields of optical communication and optoelectronic integration, fiber optic connectors, as key optoelectronic devices, function primarily to achieve fast, reliable, and low-loss alignment and connection between two optical fibers. A typical fiber optic connector (such as FC, SC, LC types) usually consists of a precision ceramic ferrule, internal components (such as springs and sleeves), and an external metal or plastic shell / housing. During the manufacturing process, to ensure the final optical performance and mechanical stability of the connector, these components need to be precisely assembled.
[0003] Press fitting is a crucial process in the back-end assembly stage of fiber optic connectors. This process typically involves using mechanical pressure to press or clamp the connector's metal housing or tail sleeve onto the pre-assembled base or main body structure. For example, after inserting the spring and ceramic ferrule into the main body, the metal back cover needs to be precisely pressed into place to secure the internal components and provide external protection and interface threads. This process demands extremely high precision: improper pressing can cause internal components to loosen, affecting mating life and optical alignment; while excessive pressing or uneven force can damage the internal ceramic ferrule or spring, directly leading to device failure.
[0004] To ensure accuracy and consistency during the press-fit process, a positioning fixture must be used to hold the semi-finished fiber optic connectors in place. However, existing general-purpose fixtures have significant shortcomings: poor positioning accuracy—they cannot precisely constrain the radial and axial positions of the fiber optic connector body, causing misalignment between the outer shell and the body during press-fitting, affecting the final coaxiality; and unstable clamping—if the fixture cannot hold the workpiece firmly under the pressure of press-fitting, the workpiece is prone to displacement, affecting not only quality but also potentially damaging the equipment. Therefore, there is an urgent need to design a positioning fixture specifically for the fiber optic connector press-fitting process. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Reference Figures 1-4A positioning fixture for an optoelectronic device includes a base plate 1 and a fixing seat 2 detachably connected to the base plate 1. The fixing seat 2 has stepped holes for bolts to secure it to the base plate 1. To improve the connection accuracy between the fixing seat 2 and the base plate 1, at least two positioning pins are installed at the bottom of the fixing seat 2. These pins are positioned by the through holes in the fixing seat 2, ensuring the installation accuracy of the fixing seat 2. A first placement groove 201 for placing a metal ferrule is provided inside the fixing seat 2. A positioning hole 202 is provided at one end of the first placement groove 201, and a limiting post 601 for fixing the metal ferrule is slidably connected to the other end of the first placement groove 201. This means that when the metal ferrule is placed in the first placement groove 201, its neck is positioned within the positioning hole 202, and the neck... The outer wall of the part fits into the inside of the positioning hole 202, and then the limiting post 601 is pushed into the metal insert. Through the combined use of the positioning hole 202 and the limiting post 601, the metal insert can be positioned and fixed, improving the use effect. The plug seat 3 is slidably connected to the base plate 1. The fixing seat 2 and the plug seat 3 are made of stainless steel, aluminum alloy or hard plastic. Here, aluminum alloy is preferred. A second placement groove 301 for placing the tail sleeve is opened on the plug seat 3. The tail sleeve is made of plastic. The end of the metal insert away from the limiting post 601 can be inserted into the tail sleeve by pressing to realize assembly. The base plate 1 is connected to a driving part for driving the plug seat 3 to slide. When the driving part works, the plug seat 3 with the tail sleeve is inserted and connected to the metal insert, that is, the metal insert is inserted into the tail sleeve to complete the initial assembly.
[0028] A contour groove 302 adapted to the shape of the tail sleeve is provided at one end of the plug socket 3 for fixing the tail sleeve. When in use, the tail sleeve is placed in the contour groove 302. The contour groove 302 not only limits the tail sleeve, but also moves the tail sleeve closer to the metal plug core to achieve the crimping effect.
[0029] Here, the drive unit includes a quick clamp 4 fixedly connected to the base plate 1. The quick clamp 4 is a push-pull type quick clamp, model number 36202. The output end of the quick clamp 4 is detachably connected to the other end of the connector 3. The connector 3 is fixed to the output end of the quick clamp 4 via a screw and nut. Two sets of guide rods 5 are fixedly connected to the base plate 1, and connecting plates 303 are fixedly connected to both sides of the connector 3. The connecting plates 303 are slidably connected to the corresponding guide rods 5. The axis of the guide rod 5 is parallel to the axis of the positioning hole 202, ensuring reliable sliding of the connector 3 during use and improving crimping accuracy. A fixing plate 501 is fixedly connected to the base plate 1, and the two ends of the guide rods 5 are fixed to the fixing plate 501 with bolts, facilitating easy assembly and disassembly and maintenance or replacement of the connector 3. Alternatively, in other embodiments, the drive unit can use a cylinder or hydraulic cylinder to drive the connector 3 to slide.
[0030] The positioning hole 202 has a cross-section of half a circle, and the limiting post 601 is coaxial with the positioning hole 202. That is, the positioning hole 202 is a semi-circular ring structure, which is used to position, support and limit the metal ferrule.
[0031] A baffle 6 is fixedly connected to the end of the limiting post 601 away from the positioning hole 202. Both the limiting post 601 and the baffle 6 are made of plastic, which can reduce wear and scratches inside the metal insert. One end of the baffle 6 abuts against the metal insert, pushing the metal insert towards the tail sleeve. Furthermore, a pull rod 602 is slidably connected to the other end of the first placement groove 201. One end of the pull rod 602 extending into the first placement groove 201 is fixedly connected to the other end of the baffle 6, and a pull plate is fixedly connected to the other end of the pull rod 602. The pull rod 602 facilitates the sliding of the limiting post 601 and the baffle 6, ensuring reliable sliding of the limiting post 601. Additionally, a spring is fitted onto the pull rod 602, with both ends of the spring abutting against the baffle 6 and the inner wall of the first placement groove 201 respectively. Under the action of the spring, the baffle 6 is always abutted against the metal insert, improving the performance.
