Description

Technical Field

[0001] This invention relates to the field of optical communication coupling fixture technology, specifically a QSFP coupling fixture. Background Technology

[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 realizing the effective transmission of optical signals between multiple optical devices. Existing coupling technologies include direct coupling, lens coupling, fiber fusion splicing coupling, and waveguide coupling. Direct coupling involves aligning 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 using direct coupling, the position and angle of the OB and CB components are highly critical. However, during the coupling of the OB and CB components, the vibration generated by the equipment during operation can cause deviations in their coupling positions, requiring constant adjustment of their positions. This not only wastes time but also reduces coupling efficiency. Summary of the Invention

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

[0005] To achieve the above objectives, the present invention provides the following technical solution: a QSFP coupling fixture, comprising a mounting base, wherein a guide rail is fixedly mounted on the upper surface of the mounting base, and further comprising: an orientation adjustment module provided above the mounting base, the orientation adjustment module comprising a first orientation adjustment platform, a second orientation adjustment platform, and a third orientation adjustment platform, wherein position sensors are provided on the opposite surfaces of the second orientation adjustment platform and the third orientation adjustment platform; an OB component fixing seat for fixing OB components is fixedly mounted on one side of the first orientation adjustment platform; CB component fixing seats for fixing CB components are respectively provided on the top surfaces of the second orientation adjustment platform and the third orientation adjustment platform; a curing module is provided above the CB component fixing seat, and the curing module is fixedly connected to the surface of the mounting base through a mounting bracket;

[0006] It also includes a compensation mechanism that can compensate for the coupling position of the CB and OB parts. The compensation mechanism includes a three-way valve. Both sets of air outlets of the three-way valve are fixedly connected to a delivery pipe. The ends of the two sets of delivery pipes are fixedly connected to an elastic hose. Both sets of elastic hoses are equipped with piston rods inside. The ends of the two sets of piston rods that are close to each other penetrate the interior of the elastic hose and extend to the outside. The ends of the two sets of piston rods that are close to each other are fixedly connected to a push plate. A moving rod is provided between the two sets of push plates. A gear is provided above the three-way valve. The gear is fixedly connected to the valve core inside the three-way valve through a rotating shaft. A rack is meshed on the surface of the gear. A limit rod is fixedly connected to one side of the rack. An electric push rod is fixedly installed on the surface of the limit rod. The electric push rod is electrically connected to a position sensor.

[0007] Furthermore, the first orientation adjustment platform is slidably engaged with the guide rail, and the second orientation adjustment platform and the third orientation adjustment platform are symmetrically and fixedly installed on the upper surface of the mounting base.

[0008] Furthermore, the lower surface of the CB component fixing seat located above the third-position adjustment platform is fixedly connected to the upper end of the third-position adjustment platform. A support plate is provided below the CB component fixing seat located on the surface of the second-position adjustment platform, and the lower end of the support plate is fixedly connected to the upper end of the second-position adjustment platform. The support plate has a cavity and an installation cavity inside. A sliding groove is provided on the bottom surface of the cavity, and a through groove is provided on the top surface of the cavity. A limiting groove is provided through the inner wall of the cavity, and the limiting groove is connected to the installation cavity.

[0009] Furthermore, the air inlet end of the three-way valve is fixedly installed on the inner wall of the cavity, and one end of the three-way valve is connected to an external air source.

[0010] Furthermore, the movable rod has an inverted T-shaped structure, and the lower end of the movable rod slides against the inner wall of the groove via a slider.

[0011] Furthermore, the upper end of the moving rod passes through the interior of the through groove and is fixedly connected to the lower end of the CB component fixing seat provided above the second orientation adjustment platform. The limiting rod is inserted into the interior of the limiting groove, and the limiting rod slides in cooperation with the inner wall of the limiting groove.

[0012] Furthermore, it also includes a micro-vibration mechanism that can vibrate the CB component fixing seat set above the second orientation adjustment platform. The micro-vibration mechanism includes a vertical rod inserted inside the moving rod. A disc is sleeved on the surface of the vertical rod. The disc is elastically connected to the inner wall of the moving rod through a connecting spring, and the connecting spring is sleeved on the surface of the vertical rod. A magnetic disk is fixedly installed at the lower end of the vertical rod, and an electromagnet is provided directly below the magnetic disk.

[0013] Furthermore, the upper end of the vertical rod is lower than the upper end of the movable rod, and the vertical rod slides against the inner wall of the movable rod through a limiting block.

[0014] Furthermore, the electromagnet is electrically connected to an external power source via a controller, and the magnetism generated by the electromagnet when energized repels the magnetism at the lower end of the magnetic disk.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0016] I. This invention utilizes a three-way valve, push plate, and electric push rod, among other cooperating components, to achieve direct coupling. By controlling the positions and angles of the second and third position adjustment platforms, and based on feedback from position sensors (i.e., when a deviation in the coupling position occurs), the electric push rod is either extended or remains stationary. When the electric push rod extends, it moves the rack via a limit rod, which in turn rotates the gears. This changes the initial connection of the three-way valve to one set of delivery pipes, connecting it to the other set. An external air source then supplies gas into the other set of delivery pipes, acting on one end of the piston rod, causing it to extend from the flexible hose. Simultaneously, the push plate pushes the moving rod laterally, and the upper end of the moving rod moves the CB component mounting base fixed to its upper end synchronously. If the electric push rod does not move, the external air source supplies gas directly into the set of delivery pipes initially connected to the three-way valve, causing the moving rod to move the CB component mounting base in another direction. This compensates for the coupling position and ensures proper coupling.

[0017] Second, this invention utilizes the coordinated use of components such as the vertical rod, connecting spring, and electromagnet. After the coupling position is adjusted, the electromagnet is intermittently energized and de-energized under the control of the controller. This causes the electromagnet to intermittently generate magnetism that repels the magnetic disk, thus intermittently pushing the vertical rod upward. This results in the upper end of the vertical rod intermittently colliding with the lower end of the CB component fixing seat above the second position adjustment platform, generating vibration. This allows the adhesive to quickly enter between the coupling components after the coupling position is adjusted, while reducing the generation of air bubbles and ensuring the quality of the coupled product.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to embodiments.

[0029] Example: A QSFP coupling fixture, such as Figures 1-7As shown, the system includes a mounting base 1, with a guide rail 2 fixedly mounted on its upper surface for guiding and limiting functions. It also includes an orientation adjustment module 3 located above the mounting base 1. The orientation adjustment module 3 includes a first orientation adjustment platform 301, a second orientation adjustment platform 302, and a third orientation adjustment platform 303. The first orientation adjustment platform 301 slides with the guide rail 2, and the second orientation adjustment platform 302 and the third orientation adjustment platform 303 are symmetrically fixedly mounted on the upper surface of the mounting base 1. These three platforms are existing technologies and can all achieve multi-directional adjustment, i.e., tilt adjustment in XYZθ+2 degrees of freedom. Position sensors are provided on the opposite surfaces of the second orientation adjustment platform 302 and the third orientation adjustment platform 303. These position sensors are existing technologies and are electrically connected to a controller. By setting the position sensors, the coupling position of the coupling components can be detected, ensuring that the coupling components can be correctly coupled.

[0030] The first azimuth adjustment platform 301 has an OB component fixing seat 4 fixedly installed on one side for fixing the OB component, so that the first azimuth adjustment platform 301 can move the OB component. It is worth noting that the OB component is the optical module, which is the core component in the optical module that realizes the photoelectric conversion function. It is responsible for converting electrical signals into optical signals for transmission and converting received optical signals into electrical signals for processing. The top surfaces of the second azimuth adjustment platform 302 and the third azimuth adjustment platform 303 are respectively provided with CB component fixing seats 5 for fixing CB components. The CB component fixing seat 5 located above the second azimuth adjustment platform 302 is used to support the OB component fixedly installed on the OB component fixing seat 4. The lower surface of the CB component fixing seat 5 located above the third azimuth adjustment platform 303 is fixedly connected to the upper end of the third azimuth adjustment platform 303.

[0031] A support plate 501 is provided below the CB component fixing seat 5 located on the surface of the second orientation adjustment platform 302, and the lower end of the support plate 501 is fixedly connected to the upper end of the second orientation adjustment platform 302. By setting the support plate 501, a support function can be provided. The support plate 501 has a cavity 5011 and an installation cavity inside. A sliding groove 5012 is provided on the bottom surface of the cavity 5011, and a through groove 5013 is provided on the top surface of the cavity 5011. A limiting groove 5014 is provided through the inner wall of the cavity 5011, and the limiting groove 5014 is connected to the installation cavity. By setting the sliding groove 5012, the through groove 5013 and the limiting groove 5014, a guiding and limiting function can be provided.

[0032] The CB part fixing base 5 is provided with a curing module 6 above it, and the curing module 6 is fixedly connected to the surface of the mounting base 1 through the mounting bracket. The curing module 6 is used to cure UV adhesive to bond the CB part and the OB part. It is worth noting that after the OB part and the CB part are connected, the existing glue injection module technology is used to start the glue injection, which is not shown in the figure, so as to bond the OB part and the CB part.

[0033] Combined with appendix Figure 1 -Appendix Figure 7 It also includes a compensation mechanism 7 that can compensate for the coupling position of the CB and OB components, so that the coupling position of the OB and CB components can be automatically compensated during coupling to ensure the accuracy of the coupling position. The compensation mechanism 7 includes a three-way valve 701. The air inlet end of the three-way valve 701 is fixedly installed on the inner wall of the cavity 5011, and one end of the three-way valve 701 is connected to an external air source. By setting the three-way valve 701, it can play the role of gas transmission and control the flow direction of the gas. Both sets of air outlets of the three-way valve 701 are fixedly connected to the delivery pipes 702. By setting the delivery pipes 702, the gas flowing through the three-way valve 701 can be delivered. The ends of the two sets of delivery pipes 702 are fixedly connected to the elastic hoses 703. By setting the elastic hoses 703, they can be compressed later to facilitate the compensation of the position when the OB and CB components are coupled.

[0034] Both sets of flexible hoses 703 are equipped with piston rods 704 inside. The ends of the two sets of piston rods 704 that are close to each other penetrate through the interior of the flexible hoses 703 and extend to the outside. By setting the piston rods 704, they can move under the action of the gas inside the delivery pipe 702. It is worth noting that the end of the piston rod 704 inside the delivery pipe 702 is in contact with the inner wall of the delivery pipe 702, ensuring that the gas will not leak from the contact point between the end of 704 inside the delivery pipe 702 and the inner wall of the delivery pipe 702. The ends of the two sets of piston rods 704 that are close to each other are fixedly connected with push plates 705. By setting the push plates 705, they can move synchronously with the piston rods 704, thus playing a pushing role. It is worth noting that the connection between the flexible hoses 703 and the delivery pipe 702 is equipped with sealing gaskets for sealing, and the position where the ends of the two sets of piston rods 704 that are close to each other penetrate the flexible hoses 703 is also equipped with sealing gaskets to ensure airtightness.

[0035] Among them, a movable rod 706 is provided between the two sets of push plates 705. The movable rod 706 has an inverted T-shaped structure, and the lower end of the movable rod 706 slides with the inner wall of the slide groove 5012 through a slider. The upper end of the movable rod 706 passes through the interior of the through groove 5013 and is fixedly connected to the lower end of the CB part fixing seat 5 provided above the second orientation adjustment platform 302. By setting the movable 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 provided above the second orientation adjustment platform 302 to move, so as to realize the position compensation when the OB part and the CB part are coupled.

[0036] 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. By setting the gear 707, the rotation of the gear 707 drives the valve core of the three-way valve 701 to rotate, changing the flow direction of the gas, so that the moving rod 706 drives the CB component fixing seat 5 provided above the second position adjustment platform 302 to move. It is worth noting that the gear 707 is rotatably sleeved on the air inlet surface of the three-way valve 701; the surface of the gear 707 is meshed with a rack 708, and a limit rod 709 is fixedly connected to one side of the rack 708. A 9 is inserted into the limiting groove 5014, and the limiting rod 709 slides in cooperation with the inner wall of the limiting groove 5014. By setting the limiting rod 709, the rack 708 can be moved when it moves. An electric push rod 710 is fixedly installed on the surface of the limiting rod 709, and the electric push rod 710 is electrically connected to the position sensor. The electric push rod 710 is installed on the inner wall of the mounting cavity and can drive the limiting rod 709 to slide inside the limiting groove 5014 through its own extension and retraction. By setting the electric push rod 710, the electric push rod 710 can be extended by transmitting the electrical signal fed back by the position sensor to the controller.

[0037] Combined with appendix Figure 1 -Appendix Figure 7It also includes a micro-vibration mechanism 8 capable of vibrating the CB component fixing seat 5 located above the second-position adjustment platform 302. This mechanism generates vibration during glue injection after the OB and CB components are coupled, facilitating rapid glue penetration between the OB and CB components while reducing air bubble formation and ensuring the quality of the coupling between them. The micro-vibration mechanism 8 includes a vertical rod 801 inserted inside the moving rod 706. The upper end of the vertical rod 801 is lower than the upper end of the moving rod 706, and the vertical rod 801 slides against the inner wall of the moving rod 706 via a limiting block. By setting the vertical rod 801, the... The vertical rod 801 can slide inside the moving rod 706 so that the upper end of the vertical rod 801 can impact the lower end of the CB component fixing seat 5 set above the second orientation adjustment platform 302; a disc 802 is sleeved on the surface of the vertical rod 801, and the disc 802 is elastically connected to the inner wall of the moving rod 706 through a connecting spring 803. The connecting spring 803 is sleeved on the surface of the vertical rod 801. By setting the disc 802 and the connecting spring 803, when the vertical rod 801 moves, the connecting spring 803 can be compressed to deform and generate a reaction force to drive the vertical rod 801 back to its original position.

[0038] A magnetic disk 804 is fixedly installed at the lower end of the vertical rod 801. An electromagnet 805 is located directly below the magnetic disk 804. The electromagnet 805 is electrically connected to an external power source through a controller. When the electromagnet 805 is energized, the magnetism it generates repels the magnetism at the lower end of the magnetic disk 804. By setting up the magnetic disk 804 and the electromagnet 805, the electromagnet 805 can generate a magnetism that repels the lower end of the magnetic disk 804 when it is energized, which is used to push the vertical rod 801 upward. It is worth noting that the electromagnet 805 is energized and de-energized through the controller, and the electromagnet 805 is intermittently energized under the action of the controller.

[0039] Specifically, when coupling the OB part and the CB part, the OB part is first placed on the OB part fixing seat 4, and then conveyed by the first orientation adjustment stage 301, and finally placed into the CB part fixing seat 5 set above the second orientation adjustment stage 302. After placement, the position of the CB part fixing seat 5 set above the second orientation adjustment stage 302 and the third orientation adjustment stage 303 is detected by the position sensor. If the coupling position of the CB part fixing seat 5 set above the second orientation adjustment stage 302 and the third orientation adjustment stage 303 is correct, then the glue injection and subsequent steps are carried out normally.

[0040] Combined with appendix Figure 2 -Appendix Figure 4If the positions of the CB component fixing seats 5 above the second position adjustment platform 302 and the third position adjustment platform 303 deviate, that is, if the position of the CB component fixing seat 5 above the second position adjustment platform 302 is to the left compared to the position of the CB component fixing seat 5 above the third position adjustment platform 303, the position sensor will feed back the result to the controller. At this time, the electric push rod 710 will not move, and the external air source will start supplying air, so that the air enters the interior of the left delivery pipe 702 through the three-way valve 701 and acts on the piston rod 704 located inside the elastic hose 703. This causes the piston rod 704 to drive the push plate 705 to push the moving rod 706 to move to the right, and simultaneously drive the CB component fixing seat 5 fixedly connected to the upper end of the moving rod 706 to move to the right. When the position sensor sends a signal indicating that the coupling position is accurate, the external air supply stops. If the position is slightly to the right, the electric push rod 710 extends and moves the rack 708 synchronously, causing the gear 707 to rotate the valve core of the three-way valve 701. This changes the initial state of the three-way valve 701 being connected to the left delivery pipe 702 to the state of the three-way valve 701 being connected to the right delivery pipe 702. This allows the gas supplied by the external air source to enter the inside of the right delivery pipe 702 and act on the piston rod 704 inside the right elastic hose 703. The right piston rod 704 then drives the push plate 705 to push the moving rod 706 to the left, thereby compensating for the coupling position and ensuring the coupling quality.

[0041] After coupling is completed, the glue injection module will begin to inject glue into the coupled OB and CB parts. During glue injection, the controller will intermittently supply power to the electromagnet 805, so that the electromagnet 805 can intermittently generate magnetism that repels the lower end of the magnetic disk 804, causing the vertical rod 801 to move up and down intermittently and collide with the CB part fixing seat 5 set above the second position adjustment platform 302. This allows the glue on the surface of the coupled OB and CB parts to quickly enter between the OB and CB parts and reduce the generation of air bubbles. After glue injection is completed, the power supply to the electromagnet 805 is stopped, and then the curing module 6 is started to cure the glue and bond the coupled CB and OB parts.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
