Description

Technical Field

[0001] This invention relates to the field of optical fiber processing technology, and more specifically, to an optical fiber ferrule polishing device. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this invention and does not constitute prior art.

[0003] With the rapid development of fiber optic technology, optical fibers, as the carrier of optical transmission, need to be connected to various control devices during transmission and control. Therefore, optical transmission plays a vital role in modern communication. Due to the precision requirements of optical signal transmission, there are also high quality standards for the end faces of optical fiber connections. The end faces of optical fiber connections typically require multiple processes during production, including adding polishing slurry, polishing, and cleaning. Currently, these toolings are scattered and independently set up. Furthermore, current polishing units, such as the optical fiber polishing machine with publication number CN115946002A, have their optical fiber ferrules mounted on a lifting bracket via polishing discs, with the polishing pads attached to a sponge pad. This requires high manufacturing and installation precision. If there are installation errors, the bottom sponge alone cannot correct them, resulting in poor consistency and flatness of the polished optical fiber ferrule surface, thus affecting product quality. Moreover, the currently independently set up tooling occupies space and is inefficient.

[0004] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention.

[0022] By employing the above technical solutions, the beneficial effects of the present invention are as follows:

[0023] This invention discloses a fiber optic ferrule polishing device. By incorporating a suspension clamping unit, it enables simultaneous polishing of fiber optic ferrules at the polishing station while suspending fiber optic cables at the loading station, effectively shortening processing time and improving efficiency. A floating mechanism suspends the polishing fixture on a support plate, and positioning the fixture above the polishing disc allows it to connect with the polishing machine naturally by gravity, ensuring consistent and even polishing. Positioning posts on the grinding disc's mounting surface and arc-shaped positioning parts on the fixture's mounting base provide effective positioning. When the mounting base connects to the polishing disc, the floating mechanism's gaps allow for position correction, preventing jamming and enabling rapid positioning. The hook design, which is both liftable and rotatable, facilitates loading and allows for the suspension of fiber optic discs of any size. The mounting tray helps organize fiber optic cables, preventing tangling. By setting up a continuous dripping component, and configuring the dripping head with a first working position and a second working position, the grinding fluid is dripped onto the grinding disc in the first working position, and dripped back into the storage tank through the return port in the second working position. A stirring rod is installed in the storage tank to achieve circulating dripping, which effectively solves the problem of grinding fluid sedimentation in the storage tank and pipeline, and effectively avoids pipeline blockage. By setting up a peristaltic pump, the output volume can be precisely controlled, and the pump body does not need to contact the grinding fluid, thus effectively solving the problem of contamination of the grinding fluid during transportation. The grinding disc is installed on the transfer component to facilitate the docking of the grinding disc with different dripping components. Because the cleaning disc consists of a disc body and a cantilever, with the connector installed at the end of the cantilever furthest from the disc body, and with the spray nozzles, the water flow is not lost when it enters from the far end of the cantilever. Instead, it accumulates in the middle, cleaning the grinding area. Furthermore, the spray nozzles of the spray units on adjacent cantilever arms are staggered, ensuring maximum thorough cleaning with fewer nozzles and avoiding repeated cleaning of the same area, thus preventing resource waste. When the cleaning disc rotates at high speed, each ring of spray nozzles becomes a water or air ring centered on the center of rotation of the cleaning disc. Due to the staggered arrangement, these water and air rings form concentric circles of varying sizes, denser in the grinding area and more evenly distributed elsewhere, achieving maximum cleaning efficiency.

The opening and closing door includes two cover plates 620 arranged at the opening of the cleaning tank 616, each cover plate 620 being driven by an opening and closing cylinder 621.

[0051] Specifically, when the suspension clamping mechanism moves the grinding fixture 12 above the cleaning tank 616, the opening and closing cylinder 621 drives the opening and closing door to open, allowing the grinding fixture 12 to enter the cleaning tank 616, come above the cleaning disc 601 and maintain a certain distance from the cleaning disc 601. At this time, the air slip ring 608 starts to rotate at high speed, thereby driving the cleaning disc 601 to rotate at high speed. The control unit turns on the water source switch, and the spray holes 606 on the cleaning disc 601 simultaneously spray a strong water flow to rinse the lower surface of the grinding fixture 12. After a few seconds, the control unit controls the water source switch to close and starts to turn on the air source switch. After the air source switch is turned on, the cleaning disc 601 will spray high-pressure air to remove water from the rinsed cleaning disc 601 to ensure that there are no stains or water stains on the cleaning disc 601. Since the cleaning disc 601 consists of two parts, a disc body 602 and a cantilever 603, and the connector 604 is installed at the end of the cantilever 603 away from the disc body 602, the water flow can be prevented from being lost when it enters from the far end of the cantilever 603. Instead, it accumulates in the middle and cleans the grinding area. Furthermore, the spray holes 606 of the spray units 605 on adjacent cantilever 603 are staggered, which ensures maximum comprehensive cleaning with fewer holes and avoids waste of resources by repeatedly cleaning the same area. When the cleaning disc 601 rotates at high speed, each ring of spray holes 606 becomes a water ring or air ring with the rotation center of the cleaning disc 601 as the center. Because they are staggered, these water rings and air rings become concentric circles of different sizes. They are denser in the grinding area, forming a dense area 607, while other areas are more uniform, achieving the maximum cleaning purpose.
