Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular to a manual three-piece coupling device. Background Technology

[0002] With the development of the optical communication industry, PON modules have gradually come into people's view, and PON module technology has become more and more mature. The optical devices in PON modules have gradually evolved from the initial one-transmit and one-receive to the current three-transmit and three-receive. Coupling, as an important process in the manufacturing of optical devices, plays a decisive role.

[0003] Currently, the coupling equipment for traditional optical communication laser devices is based on two-piece coupling. When facing the multi-transmitter and multi-receiver combination structure in PON modules, it becomes very difficult to verify the coupling of the optical path. It is necessary to change the structural design of the equipment, match the required fixtures, increase costs, and make the coupling process more complicated.

[0004] The manual three-piece coupling device of this utility model adopts the cooperation of a six-dimensional adjustment frame and a clamping bracket. It can complete the optical path coupling verification of multi-transmitter and multi-receiver optical devices in PON modules without the need for complex structural matching. The design is relatively simple and easy to operate. Utility Model Content

[0005] The purpose of this invention is to provide a manual three-piece coupling device that uses a six-dimensional adjustment frame and a clamping bracket to complete the optical path coupling verification of multi-transmitter and multi-receiver optical devices in a PON module without the need for complex structural matching. The design is relatively simple and easy to operate, and it can be compatible with the optical path coupling verification of different types of optical devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A manual three-piece coupling device includes a portable optical platform, a six-dimensional adjustment frame, a fixed base, a sliding base, a displacement stage, a tube clamping bracket, a transmitter clamping bracket, and a receiver clamping bracket. A fixed base and two sliding bases are fixed to the portable optical platform. The tube clamping bracket is mounted on one sliding base via the displacement stage. The transmitter clamping bracket is mounted on one sliding base via the six-dimensional adjustment frame. The receiver clamping bracket is mounted on the fixed base via the six-dimensional adjustment frame. The tube clamping bracket is located between the transmitter clamping bracket and the receiver clamping bracket.

[0008] The tube clamping bracket includes a clamping arm, a clamping fixing plate, and a tube clamping block. The clamping arm is fixed to the upper end of the displacement platform. The clamping fixing plate is horizontally arranged at the upper end of the clamping arm. The tube clamping block is fixed to the end of the clamping fixing plate.

[0009] The transmitter clamping bracket is generally right-angled, with its vertical surface connected to the six-dimensional adjustment frame. Its horizontal end has a square clamping opening and is fitted with clamping screws on its side. This transmitter clamping bracket is used to clamp BOX-packaged emitting optical devices.

[0010] The transmitter clamping bracket is generally right-angled, with its vertical surface connected to the six-dimensional adjustment frame. Its horizontal end has a pentagonal clamping opening and is fitted with clamping screws on its side. This transmitter clamping bracket is used to clamp a coaxially packaged TO-CAN transmitter.

[0011] The receiver clamping bracket is generally right-angled, with its vertical surface connected to the six-dimensional adjustment frame.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] like Figures 1-5As shown, a manual three-piece coupling device includes a portable optical platform 1, a six-dimensional adjustment frame 19, a fixed base 8, a sliding base 2, a displacement stage 18, a tube clamping bracket, a transmitter clamping bracket, and a receiver clamping bracket 7. A fixed base 8 and two sliding bases 2 are fixed on the portable optical platform 1. The tube clamping bracket is mounted on a sliding base 2 via the displacement stage 18. The transmitter clamping bracket is mounted on a sliding base 2 via the six-dimensional adjustment frame 19. The receiver clamping bracket 7 is mounted on the fixed base 8 via the six-dimensional adjustment frame 19. The tube clamping bracket is located between the transmitter clamping bracket and the receiver clamping bracket 7.

[0027] See Figure 1 and Figure 3 The tube clamping bracket includes a clamping arm 6, a clamping fixing plate 5, and a tube clamping block 4. The clamping arm 6 is fixed to the upper end of the displacement stage 18. The clamping fixing plate 5 is horizontally arranged at the upper end of the clamping arm 6. The tube clamping block 4 is fixed to the end of the clamping fixing plate 5. The upper end face of the tube clamping block 4 is provided with a horizontal clamping port 20 and a clamping screw 15 is provided at the end. The end of the tube clamping block is provided with a longitudinal clamping port 21 and a clamping screw 15 is provided on the side.

[0028] See Figure 1 and Figure 2 The transmitter clamping bracket is generally right-angled, with its vertical surface connected to the six-dimensional adjustment frame 19. Its horizontal end has a square clamping opening and a clamping screw 15 on its side. When the transmitting device is a BOX-packaged optical transmitter, this transmitter clamping bracket serves as the BOX-packaged clamping bracket 3 to clamp the BOX-packaged optical transmitter, and is connected to the six-dimensional adjustment frame 19 with bolts. The BOX-packaged optical transmitter is locked and fixed in the square clamping opening using the clamping screw 15.

[0029] See Figure 1 and Figure 5 The transmitter clamping bracket is generally right-angled, with its vertical surface connected to the six-dimensional adjustment frame 19. Its horizontal end has a pentagonal clamping opening and a clamping screw 15 on its side. This transmitter clamping bracket is a TO-CAN transmitter clamping bracket 22. When the transmitting device is a coaxially packaged TO-CAN transmitter, the TO-CAN transmitter clamping bracket 22 is connected to the six-dimensional adjustment frame 19 with bolts to clamp the coaxially packaged TO-CAN transmitter. The coaxially packaged TO-CAN transmitter is locked and fixed in the pentagonal clamping opening using the clamping screw 15.

[0030] See Figure 1 , Figure 4The receiver clamping bracket 7 is generally right-angled, with its vertical surface connected to the six-dimensional adjustment bracket 19. Its horizontal end has a pentagonal clamping opening and a clamping set screw 15 on its side. It is used to clamp coaxially packaged TO-CAN receivers or pins.

[0031] The sliding base 2 includes a base 16, a slide rail 17, and a slide table 9. The slide rail 17 is fixed on the base, and the slide table 9 is slidably connected to the slide rail 17.

[0032] The six-dimensional adjustment frame 19 is assembled from an X-axis displacement stage 10, a Y-axis displacement stage 11, an X-axis arc swing stage 13, a Y-axis arc swing stage 12, and a Z-axis displacement stage 14.

[0033] The manual three-piece coupling device is precisely aligned using a sliding base 2 (base 16 and X-axis slide rail displacement stage), X-axis displacement stage 10, Y-axis displacement stage 11, X-axis arc swing stage 13, Y-axis arc swing stage 12 and Z-axis displacement stage 14. The position of the BOX-packaged emitting optical device is fixed using a BOX-packaged clamping bracket 3. The position of the coaxially packaged emitting TO-CAN is fixed using a TO-CAN emitting clamping bracket 22. The position of the tube is fixed using a tube clamping block 4. The position of the receiving TO-CAN is fixed using a receiving clamping bracket 7.

[0034] In the above scheme, the transmitting element, tube body and receiving element are aligned and assembled by displacement stage, clamping bracket and set screw. The assembly is easy and the structure is simple. They are all distributed in the portable optical platform 1. The overall space structure is small and can be used anytime and anywhere.

[0035] The launch clamping device includes a six-dimensional adjustment frame 19 assembled from an X-axis displacement stage 10, a Y-axis displacement stage 11, an X-axis arc swing stage 13, a Y-axis arc swing stage 12 and a Z-axis displacement stage 14, and a sliding base 2. Each displacement stage is mechanically positioned and assembled to meet the multi-directional and multi-dimensional movement requirements of the BOX or the launch TO-CAN.

[0036] The tube clamping device includes a sliding base 2, a displacement stage 18 (Y-axis), a clamping arm 6, a clamping fixing plate 5, and a tube clamping block 4, which are connected to each other by screws to ensure that the tube can move in the X-axis and Y-axis directions.

[0037] The receiving clamping device includes a fixed base 8, and a six-dimensional adjustment frame 19 assembled from an X-axis displacement stage 10, a Y-axis displacement stage 11, an X-axis arc swing stage 13, a Y-axis arc swing stage 12 and a Z-axis displacement stage 14. Each displacement stage is assembled in sequence to enable the pin or the receiving TO-CAN to move in all directions.

[0038] The BOX package clamping bracket 3 and the TO-CAN transmitter clamping bracket 22 can be disassembled and replaced according to the coupling requirements of the transmitter device. When performing BOX optical path coupling, the BOX package clamping bracket 3 is used for fixation, while when performing TO-CAN optical path coupling, the TO-CAN transmitter clamping bracket 22 is used for fixation. Figure 1 The image only shows an assembly diagram of the BOX-packaged clamping bracket 3.

[0039] Further preferably, the tube clamping block 4 supports both lateral and longitudinal clamping. In this design, the tube clamping block 4 is provided with two clamping ports to facilitate lateral or longitudinal optical path coupling of the optical device, and is fully compatible with the needs of manual two-piece coupling.

[0040] In a more optimized design, the portable optical platform 1 has screw holes arranged in a linear array. The transmitting clamp, tube clamp, and receiving clamp are all secured to the portable optical platform with screws. The screw holes on the portable optical platform 1 ensure clamping stability and also provide positioning functionality.

[0041] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The manual three-piece coupling device provided in this embodiment includes a transmitter clamping device, a tube clamping device, a receiver clamping device, and a portable optical platform 1. The transmitter clamping device, the tube clamping device, and the receiver clamping device are all fixed on the portable optical platform 1.

[0042] like Figure 2 and Figure 5As shown, the launch clamping device includes a base 16, a slide rail 17 and a slide table 9 (i.e., an X-axis slide rail displacement table), an X-axis displacement table 10, a Y-axis displacement table 11, an X-axis arc swing table 13, a Y-axis arc swing table 12, a Z-axis displacement table 14, a BOX-packaged clamping bracket 3, a TO-CAN launch clamping bracket 22, and a clamping set screw 15. The assembly method is as follows: First, fix the X-axis slide rail displacement table on the base 16. The X-axis slide rail displacement table can significantly increase the displacement stroke in the X-axis direction; then connect and assemble the X-axis displacement table 10, the Y-axis displacement table 11, the X-axis arc swing table 13, the Y-axis arc swing table 12, and the Z-axis displacement table 14 in sequence. The X-axis displacement stage 10 is positioned above the Y-axis displacement stage 11, or the Y-axis displacement stage 11 is positioned above the X-axis displacement stage 10. The X-axis arc swing stage 13 and the Y-axis arc swing stage 12 are positioned above both the X-axis displacement stage 10 and the Y-axis displacement stage 11. The X-axis arc swing stage 13 and the Y-axis arc swing stage 12 can be interchanged for assembly. The X-axis arc swing stage 13 and the Y-axis arc swing stage 12 enable the BOX or the TO-CAN transmitter to swing upwards in the X-axis and Y-axis directions. Then, the Z-axis displacement stage 14 is installed on the X-axis arc swing stage 13 or the Y-axis arc swing stage 12. Finally, the BOX packaging clamping bracket 3 or the TO-CAN transmitter clamping bracket 22 is mechanically positioned and assembled on the Z-axis displacement stage 14. The clamping set screw 15 is screwed into the BOX packaging clamping bracket 3 or the TO-CAN transmitter clamping bracket 22. The clamping set screw 15 can be used to lock the BOX or the TO-CAN transmitter.

[0043] like Figure 3 As shown, the pipe clamping device includes a base 16, a slide rail 17 and a slide table 9 (i.e., an X-axis slide rail displacement table), a displacement table 18 (Y-axis), a clamping arm 6, a clamping fixing plate 5, a pipe clamping block 4, and two clamping set screws 15. The assembly method is as follows: First, assemble the X-axis slide rail displacement table onto the base 16. As mentioned above, the X-axis slide rail displacement table can increase the displacement. Second, install the displacement table 18 (Y-axis) onto the X-axis slide rail displacement table 2. Third, mechanically assemble the clamping arm 6 onto the displacement table 18 (Y-axis). Fourth, connect the clamping arm 6 and the clamping fixing plate 5. Fifth, assemble the pipe clamping block 4 onto the clamping fixing plate 5. Finally, screw the two clamping set screws 15 into the pipe clamping block 4 to complete the assembly of the pipe clamping device.

[0044] It should be noted here that, Figure 3 The tube clamping device shown only has an X-axis slide rail displacement stage and a displacement stage 18 (Y-axis). This is because both the transmitting and receiving clamping devices have X-axis and Y-axis arc swing stages, which can basically meet the requirements of three-piece coupling. Therefore, the tube clamping device does not have X-axis and Y-axis arc swing stages to reduce costs. However, for higher precision coupling requirements, it is also possible to arrange X-axis and Y-axis arc swing stages accordingly.

[0045] like Figure 4As shown, the receiving clamping device includes a fixed base 8, an X-axis displacement stage 10, a Y-axis displacement stage 11, an X-axis arc swing stage 13, a Y-axis arc swing stage 12, a Z-axis displacement stage 14, a receiving clamping bracket 7, and a clamping set screw 15. The assembly method is as follows: First, assemble the X-axis displacement stage 10 or the Y-axis displacement stage 11 onto the fixed base 8. Since the X-axis displacement stage 10 can be placed above or below the Y-axis displacement stage 11, either the X-axis displacement stage 10 or the Y-axis displacement stage 11 can be assembled onto the fixed base 8 first. Next, assemble the remaining X-axis displacement stage 10 or the Y-axis displacement stage 11. Then, assemble the X-axis arc swing stage 13 and the Y-axis arc swing stage 12. Similarly, the X-axis arc swing stage 13 and the Y-axis arc swing stage 12 can be assembled by exchanging their upper and lower positions to ensure that the pin or the TO-CAN receiver can be operated by arc swinging upwards in the X-axis and Y-axis directions. Next, assemble the Z-axis displacement stage 14 onto the X-axis arc swing stage 13 or the Y-axis arc swing stage 12. Finally, assemble the receiver clamping bracket 7 onto the Z-axis displacement stage 14, and screw the clamping set screw 15 into the receiver clamping bracket 7. The clamping set screw 15 is used to lock and fix the pin or the TO-CAN receiver.

[0046] It should be noted that the assembly of the above-mentioned transmitter clamping device, tube clamping device and receiver clamping device is all mechanically positioned and assembled by connecting screws.

[0047] like Figure 2 and Figure 5 As shown, the transmitter clamping device of this utility model adopts two design schemes for the transmitter clamping bracket, namely the BOX-encapsulated clamping bracket 3 and the TO-CAN transmitter clamping bracket 22. The purpose is to be compatible with the clamping and fixing of BOX and TO-CAN transmitters, but... Figure 1 The diagram only shows the assembly of the BOX package clamping bracket 3. When the BOX optical device is coupled, the BOX package clamping bracket 3 is used for clamping and fixing; when the TO-CAN optical device is to be coupled, the screws connecting the BOX package clamping bracket 3 and the six-dimensional adjustment bracket 19 are unscrewed, and the TO-CAN transmitter clamping bracket 22 is replaced and assembled.

[0048] like Figure 3 As shown, the tube clamping block 4 in the tube clamping device adopts a design with horizontal and vertical clamping ports. When the optical device needs to be coupled horizontally in a two-piece manner, the tube is locked and fixed by the clamping set screw 15 and the horizontal clamping port 20. The tube clamping device and the receiving clamping device move and cooperate to achieve precise alignment and coupling. When the optical device needs to be coupled vertically in a three-piece manner or in a two-piece manner, the tube is locked and fixed by the clamping set screw 15 and the vertical clamping port 21. The transmitting clamping device, the tube clamping device, and the receiving clamping device move and cooperate according to the actual use requirements to achieve the coupling purpose.

[0049] like Figure 1As shown, the transmitting clamping device, the tube clamping device, and the receiving clamping device are all fixed to the portable optical platform 1. Screw holes are equidistantly arranged on the portable optical platform 1. The fixed base 8 and the base 16 are both provided with double-sided slots. The screws can be aligned and locked through the slots with the screw holes of the portable optical platform 1 to fix and limit the three clamping devices, which not only ensures the stability of the three clamping devices, but also ensures the assembly accuracy.

[0050] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
