Description

Technical Field

[0001] The present invention relates to the technical field of optical communication coupling fixtures, and in particular to a QSFP coupling fixture. Background Art

[0002] Optical communication coupling refers to the process of efficiently and accurately transmitting optical signals from a light source to an optical fiber or other optical device, or achieving effective transmission of optical signals between multiple optical devices. Existing coupling technologies include direct coupling, lens coupling, fiber fusion coupling, and waveguide coupling. Direct coupling is to align the light source (such as a laser diode) directly with the end face of the optical fiber, allowing light to enter the optical fiber directly.

[0003] Therefore, when direct coupling is used for coupling, very high requirements are placed on the position and angle of the OB and CB components. When the OB and CB components are coupled, the vibration generated by the equipment during operation may cause deviations in the coupling position of the OB and CB components. It is necessary to constantly adjust the position of the OB and CB components, which not only wastes time but also reduces the coupling efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a QSFP coupling fixture to solve the problem in the prior art proposed in the above background art that direct coupling requires constant position adjustment, which wastes time and affects coupling efficiency.

[0006] Furthermore, the first orientation adjustment platform is in sliding cooperation with the guide rail, and the second orientation adjustment platform and the third orientation adjustment platform are symmetrically fixedly mounted on the upper surface of the mounting base.

[0007] Furthermore, the lower surface of the CB part fixing seat located above the third orientation adjustment platform is fixedly connected to the upper end of the third orientation adjustment platform, and a support plate is provided below the CB part fixing seat located on the surface of the second orientation adjustment platform, and the lower end of the support plate is fixedly connected to the upper end of the second orientation adjustment platform, a cavity and an installation cavity are provided inside the support plate, a sliding groove is provided on the bottom surface of the cavity, a through groove is provided on the top surface of the cavity, a limiting groove is provided on the inner wall of the cavity, and the limiting groove is communicated with the installation cavity.

[0008] Furthermore, the air inlet end of the three-way valve is fixedly mounted on the inner wall of the cavity, and one end of the three-way valve is connected to an external air source.

[0009] Furthermore, the moving rod is in an inverted T-shaped structure, and the lower end of the moving rod is slidably engaged with the inner wall of the sliding groove through a slider.

[0010] Furthermore, the upper end of the movable rod passes through the interior of the through slot and is fixedly connected to the lower end of the CB part fixing seat arranged above the second orientation adjustment platform. The limit rod is inserted into the interior of the limit slot, and the limit rod slides with the inner wall of the limit slot.

[0011] Furthermore, it also includes a micro-seismic mechanism that can vibrate the CB part fixing seat arranged above the second azimuth adjustment platform. The micro-seismic mechanism includes a vertical rod inserted into the inside of the moving rod, and a circular disk is sleeved on the surface of the vertical rod.

[0013] Furthermore, the electromagnet is electrically connected to an external power supply through a controller, and the magnetism generated by the electromagnet when energized repels the magnetism at the lower end of the magnetic disk.

[0014] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The present invention is provided with a three-way valve, a push plate, an electric push rod and other components that cooperate with each other. Then, when a direct coupling method is adopted, after controlling the position and angle of the second azimuth adjustment platform and the third azimuth adjustment platform, according to the feedback result of the position sensor, that is, when the coupling position deviates, the electric push rod is controlled to start extending or not to move. When the electric push rod is extended, the rack is driven to move through the limit rod and the gear is driven to rotate, so that the state of the three-way valve being connected to one set of delivery pipes in the initial state is changed to being connected to the other set of delivery pipes. Then, the external air source is turned on to supply gas, so that the gas enters the interior of the other set of delivery pipes and acts on one end of the piston rod, so that the piston rod begins to extend from the interior of the elastic hose. At the same time, the push plate pushes the moving rod to move horizontally, and the upper end of the moving rod drives the CB part fixing seat fixed to its upper end to move synchronously; if the electric push rod does not move, the external air source supply will directly pass into the set of delivery pipes that are connected to the three-way valve in the initial state, so that the moving rod drives the CB part fixing seat to move in the other direction, thereby achieving compensation of the coupling position and ensuring normal coupling.

[0015] 2. The present invention cooperates with the vertical rod, connecting spring, electromagnet and other components, and after the coupling position adjustment is completed, the electromagnet will intermittently turn on and off the power under the action of the controller, so that the electromagnet intermittently generates magnetism that repels the magnetic disk, and then can intermittently push the vertical rod upward, so that the upper end of the vertical rod intermittently collides with the lower end of the CB part fixing seat set above the second azimuth adjustment platform, generating vibration, so that after the coupling position adjustment is completed, when the glue is injected, the glue can quickly enter between the coupling parts, while reducing the generation of bubbles, thereby ensuring the quality of the coupled product.

The moving rod 706 is an inverted T-shaped structure, and the lower end of the moving rod 706 slides with the inner wall of the slide groove 5012 through a slider. The upper end of the moving rod 706 penetrates the interior of the through groove 5013 and is fixedly connected to the lower end of the CB part fixing seat 5 set above the second azimuth adjustment platform 302. By setting the moving rod 706, it can slide along the slide groove 5012 under the push of the push plate 705, and at the same time drive the CB part fixing seat 5 set above the second azimuth adjustment platform 302 to move, thereby realizing position compensation when the OB part and the CB part are coupled.

[0025] Among them, a gear 707 is provided above the three-way valve 701, and the gear 707 is fixedly connected to the valve core inside the three-way valve 701 through a rotating shaft.

[0026] Combined with attachment Figure 1 -Attached Figure 7, and also includes a micro-vibration mechanism 8 that can vibrate the CB component fixing seat 5 set above the second orientation adjustment platform 302, so that when the OB component and the CB component are coupled and then glue is injected, vibration can be generated, which facilitates the glue to quickly enter between the OB component and the CB component, while reducing the generation of bubbles and ensuring the quality of the coupling between the OB component and the CB component; the micro-vibration mechanism 8 includes a vertical rod 801 inserted into the interior of the mobile rod 706, the upper end of the vertical rod 801 is lower than the upper end of the mobile rod 706, and the vertical rod 801 is slidably matched with the inner wall of the mobile rod 706 through a limit block.

By arranging the disk 802 and the connecting spring 803, when the vertical rod 801 moves, the connecting spring 803 is compressed to cause it to deform and generate a reaction force, which is used to drive the vertical rod 801 to return to its original position; Among them, a magnetic disk 804 is fixedly installed at the lower end of the vertical rod 801, and an electromagnet 805 is provided directly below the magnetic disk 804. The electromagnet 805 is electrically connected to an external power supply through a controller. The magnetism generated by the electromagnet 805 when it is energized repels the magnetism at the lower end of the magnetic disk 804. By setting the magnetic disk 804 and the electromagnet 805, when the electromagnet 805 is energized, it generates magnetism that repels the lower end of the magnetic disk 804, which is used to push the vertical rod 801 upward. It is worth noting that the electromagnet 805 is powered on and off by the controller, and the electromagnet 805 is intermittently energized under the action of the controller.

[0027] Specifically, when coupling the OB component and the CB component, the OB component is first placed on the OB component fixing seat 4, then transported by the first orientation adjustment platform 301, and finally placed in the CB component fixing seat 5 set above the second orientation adjustment platform 302. After the placement is completed, the position of the CB component fixing seat 5 set above the second orientation adjustment platform 302 and the third orientation adjustment platform 303 is detected by the position sensor. If the coupling position of the CB component fixing seat 5 set above the second orientation adjustment platform 302 and the third orientation adjustment platform 303 is correct, the glue injection and subsequent steps are carried out normally; Combined with attachment Figure 2 -Attached Figure 4If the position of the CB component fixing seat 5 set above the second orientation adjustment platform 302 and the third orientation adjustment platform 303 deviates, that is, the position of the CB component fixing seat 5 above the second orientation adjustment platform 302 is biased to the left compared with the position of the CB component fixing seat 5 set above the third orientation adjustment platform 303, the position sensor feeds back the result to the controller, and the electric push rod 710 does not move at this time. The external gas source starts to supply gas, so that the gas enters the interior of the left delivery pipe 702 through the three-way valve 701 and acts on the piston rod 704 provided inside the elastic hose 703, so that the piston rod 704 drives the push plate 705 to push the moving rod 706 to move to the right, and drives the CB component fixing seat 5 fixedly connected to the upper end of the moving rod 706 to move to the right synchronously. Until the position sensor feeds back a signal indicating that the coupling position is accurate, the gas supply from the external gas source is stopped; if the position is biased to the right, the electric push rod 710 begins to extend, and at the same time drives the rack 708 to move synchronously, so that the gear 707 drives the valve core of the three-way valve 701 to start rotating, thereby changing the initial state in which the three-way valve 701 is connected to the left delivery pipe 702 to the state in which the three-way valve 701 is connected to the right delivery pipe 702, so that the gas provided by the external gas source enters the inside of the right delivery pipe 702 and acts on the piston rod 704 inside the right elastic hose 703, so that the right piston rod 704 drives the push plate 705 to push the moving rod 706 to move to the left, thereby achieving compensation of the coupling position and ensuring the coupling quality; After the coupling is completed, the glue injection module will start to inject glue into the coupled OB parts and CB parts. While injecting glue, the controller will intermittently power the electromagnet 805, so that the electromagnet 805 can intermittently generate magnetism that repels the lower end of the magnetic disk 804, so that the vertical rod 801 can intermittently move up and down, and collide with the CB part fixing seat 5 set above the second orientation adjustment platform 302, so that the glue on the surface of the coupled OB parts and CB parts can quickly enter between the OB parts and the CB parts, and reduce the generation of bubbles; after the glue injection is completed, stop energizing the electromagnet 805, and then start the curing module 6 to cure the glue and bond the coupled CB parts and OB parts.
