Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber array assembly, and specifically relates to a novel optical fiber array assembly fixture. Background Art

[0002] A fiber array (FA) is an optical device formed by attaching optical fibers to a substrate using precision machining techniques. Its core structure consists of a substrate, a pressure plate, and optical fibers. The substrate is typically made of glass, silicon, or ceramic with a low coefficient of expansion. V-grooves are machined onto the surface using precision scribing techniques to create the positioning of the optical fibers. A fiber array is constructed by mounting a bundle of optical fibers or a fiber ribbon onto a substrate at specified intervals using a V-grooved substrate. The process for manufacturing a fiber array involves placing the bare optical fibers, after removing their coating, into the V-grooves, applying pressure with a pressurizer, bonding them with an adhesive, and finally grinding and polishing the surface to the required precision.

[0003] The applicant has been browsing and researching a large amount of relevant records and materials on the relevant technologies regarding the curing of adhesives during the assembly of optical fiber arrays for a long time. At the same time, relying on relevant resources, the applicant has conducted a large number of relevant experiments and found that the existing optical fiber array assembly devices all have different degrees of light blocking effects, which makes the actual light intensity reaching the optical fiber array head glue during UV curing much weaker than the set light intensity, resulting in technical problems such as deviation between the actual light intensity and the set light intensity in the curing process design, leading to serious defective products.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies.

[0005] Therefore, in order to solve the above problems, the utility model provides a novel optical fiber array assembly fixture. Utility Model Content

[0006] In order to overcome the above technical problems, the purpose of the present invention is to provide a new type of optical fiber array assembly fixture.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0009] The clamp assembly includes a gantry fixedly connected to the upper seat by bolts, a movable rod is slidably connected to the gantry, a spring is sleeved on the movable rod, and a thimble is installed at the bottom end of the movable rod.

[0010] Furthermore, a mounting groove is provided inside the base, the mounting groove is communicated with the hollow groove, and a UV lamp is installed inside the mounting groove.

[0011] Furthermore, the spring is arranged below the gantry and above the limiting seat at the bottom end of the movable rod, and a handle is fixedly installed on the top end of the movable rod.

[0012] Furthermore, the position adjustment assembly includes a motor seat and a track frame fixedly mounted at one end of the base, a motor is fixedly mounted on the top of the motor seat, the output end of the motor is connected to a screw rod through a coupling, a slider is threadedly connected to the screw rod, the slider is slidably connected to the track frame, and the track frame is connected to the limit assembly.

[0013] Furthermore, the limiting assembly includes a connecting block slidably connected to the track frame, the connecting block is fixedly connected to the slider, a guide rail is installed on the top of the connecting block, two groups of symmetrically distributed limiting blocks are installed on the top of the guide rail, and limiting clamping rods are installed on each of the limiting blocks.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, UV curing can be achieved from the bottom of the fixture through the glass base. The transmittance of the optical glass is greater than 95%, which can achieve a small loss of light intensity reaching the optical fiber array head glue, and achieve the effect of minimal difference between the set light intensity and the actual light intensity, ensuring that the process design achieves the expected effect; the optical glass base is completely fitted with the optical fiber array, with no obstruction in the middle, so that the UV light of the optical fiber array head glue can be uniform, avoiding stress caused by uneven curing and achieving the optimization of the head glue curing effect.

[0016] 2. In the utility model, the spring-loaded clamp assembly on the top of the glass base can be used to assemble optical fiber arrays of various sizes and structures. When in use, the movable rod is lifted to adjust the ejector pin to a high position. After the optical fiber array device is assembled on the glass base, the movable rod is slowly released, and the spring acts to press the ejector pin against the cover plate. This structure is simple to operate, has high assembly efficiency, and good results.

[0017] 3. In the present invention, by installing a UV lamp and a reflector on the base, the optical fiber array device can be UV pre-cured without disassembling the device, avoiding the problem of the assembled optical fiber array being displaced due to vibration during the disassembly process, thereby greatly improving the assembly effect of the optical fiber array device and increasing the yield rate.

A position adjustment component 7 is installed at one end of the base 1, and a limit component 8 is assembled above the position adjustment component 7. The position adjustment component 7 can drive the limit component 8 to move back and forth, thereby facilitating the limit component 8 to limit different optical fiber array devices;

[0027] See also Figure 2 The clamp assembly 6 includes a gantry 61 fixedly connected to the upper seat 2 by bolts, and a movable rod 62 is slidably connected to the gantry 61, and a spring 63 is sleeved on the movable rod 62. A thimble 64 is installed at the bottom end of the movable rod 62. The thimble 64 is moved upward by pulling up the movable rod 62. At this time, the spring 63 is in a compressed state. After the optical fiber array device is assembled on the glass base 3, the movable rod 62 is slowly released, and the thimble 64 is driven to move downward by the restoring force of the spring 63, and then the optical fiber array device is pressed by the thimble 64. The structure is simple to operate and the assembly effect is good.

[0028] See also Figure 2 A mounting groove is provided inside the base 1, which is communicated with the hollow groove, and a UV lamp 5 is installed inside the mounting groove. The UV lamp 5 emits light to ensure that the light intensity reaches the standard value during use of the device.

[0029] See also Figure 2 The spring 63 is arranged below the gantry 61 and above the limit seat at the bottom end of the movable rod 62. A handle 65 is fixedly installed on the top of the movable rod 62. The handle 65 is convenient for the staff to operate. The spring 63 is limited in a certain area, which can stably ensure its working effect.

[0030] See also Figure 4 The position adjustment component 7 includes a motor base 71 and a track frame 72 fixedly mounted at one end of the base 1. A motor 73 is fixedly mounted on the top of the motor base 71. The output end of the motor 73 is connected to a screw rod 75 through a coupling 74. A slider 76 is threadedly connected to the screw rod 75. The slider 76 is slidably connected to the track frame 72. The track frame 72 is connected to the limit assembly 8. The motor 73 drives the screw rod 75 to rotate, and the screw rod 75 drives the slider 76 to move on the track frame 72. The limit assembly 8 is driven back and forth by the slider 76, which is convenient for the staff to operate later.

[0031] See also Figure 4 The limiting assembly 8 includes a connecting block 81 slidably connected to the track frame 72, the connecting block 81 is fixedly connected to the slider 76, a guide rail 82 is installed on the top of the connecting block 81, and two groups of symmetrically distributed limiting blocks 83 are installed on the top of the guide rail 82.

Through the movement of the two groups of limiting blocks 83 on the guide rail 82, one end of the limiting clamping rod 84 can limit the optical fiber array device, thereby ensuring the stability of the optical fiber array device during processing.

[0032] The working principle of the novel optical fiber array assembly fixture of the utility model patent is as follows: when performing the optical fiber array assembly operation, the motor 73 is first used to drive the screw rod 75 to rotate, and the screw rod 75 drives the slider 76 to move on the track frame 72, and the slider 76 drives the limit assembly 8 to move back and forth. After the position of the limit assembly 8 is determined, the V-groove substrate is placed on the surface of the glass base 3 and fixed with the clamp provided by the glass base 3. Then, the exposed part of the optical fiber is removed from the coating and clamped into the V-groove of the substrate. The optical fibers to be assembled are arranged neatly through the V-groove substrate and placed in the optical fiber array upper cover (the ejector pin 64 is in the lifted state at this time). Then, the two sets of limit blocks 83 are moved on the guide rail 82, so that one end of the limit clamp rod 84 can limit the optical fiber array device. Thereby ensuring the stability of the optical fiber array device during processing, and then slowly releasing the movable rod 62, the spring 63 restoring force drives the ejector pin 64 to move down, and then the optical fiber array device is pressed by the ejector pin 64. The structure is simple to operate and has a good assembly effect. The light array substrate is placed in the same horizontal position, and the adhesive is manually dispensed at the head position of the light array. Wait for the adhesive to flow along the V-groove to fill the entire light array, and then UV curing can be completed. This device can stably and efficiently complete the optical fiber array assembly operation. The optical glass can be UV cured from the bottom of the fixture. The transmittance of the optical glass is >95%, which can achieve a small loss of light intensity reaching the optical fiber array head glue, and achieve an effect with a small difference between the set light intensity and the actual light intensity, ensuring that the process design achieves the expected effect.
