[0040] The following is combined with Figure 3-10 This application is described in further detail.

[0041] The embodiment of the present application discloses an OSA optical component assembly device.

[0042] refer to Figure 3 and Figure 4 The OSA optical component assembly device includes a base 2, a first positioning block 3 and a second positioning block 4 which are arranged in sequence from bottom to top. The first positioning block 3 is used to fix the light emitting sub-device 12, and the second positioning block 4 is used to locate the position of the base 11, so that the orientation of the pin 121 of the light emitting sub-device 12 and the base 11 are fixed, and the light emitting sub-device 12 is fixed in the mounting hole 111 of the base 11 under the action of external pressure.

[0043] The base 2 is a cylindrical structure, the first positioning block 3 and the second positioning block 4 can both be circular plate structures, and the second positioning block 4 can be fixedly connected to the base 2 by bolts. The first positioning block 3 is located between the base 2 and the second positioning block 4, and the first positioning block 3 can move relative to the base 2 and fix its position.

[0044] Specifically, a guide column 22 is fixed on the base 2, combined with Figures 5 to 7 , a guide groove 32 cooperating with the guide column 22 is provided on the first positioning block 3, and the guide groove 32 can slide along the guide column 22. Here, the guide column 22 is integrally arranged at the edge of the base 2, and the guide column 22 has a positive angle. Correspondingly, the guide groove 32 is provided at the edge of the first positioning block 3, and the guide groove 32 has a negative angle. There are four guide columns 22 and they are evenly distributed along the circumference of the base 2, and the guide grooves 32 correspond to the guide columns 22 one by one.

[0045] refer to Figure 5and Figure 8 The center of the first positioning block 3 is provided with four through holes 35, the aperture of the through holes 35 matches the outer diameter of the pins 121 of the light emitting sub-device 12 to be assembled, and the four through holes 35 are distributed in an array in the center of the first positioning block 3. The four pins 121 of the light emitting sub-device 12 can be LD-, PD+, LD+ / PD-, and CASE in sequence.

[0046] A rectangular placement opening 42 is provided at the center of the second positioning block 4, and the contour of the placement opening 42 matches the outer contour of the base 11 to be assembled. Eight positioning holes 41 are evenly distributed along the circumference of the edge of the second positioning block 4, and the second positioning block 4 can be fixed on the guide column 22 by bolts passing through the positioning holes 41. The positioning holes 41 are preferably countersunk holes. In this way, eight riveting positions can be provided.

[0047] If the background technology Figure 2 a is the initial installation position. Figure 2 b, the base 11 and the light emitting sub-device 12 need to be rotated 45° relative to each other. After the pin 121 of the light emitting sub-device 12 is correspondingly inserted into the through hole 35 of the first positioning block 3, the second positioning block 4 is rotated 45° and fixed in position. Then, the position of the base 11 inserted into the placement port 42 meets the requirements. After the base 11 and the light emitting sub-device 12 are assembled, the orientation accuracy of the pin 121 is high. When the second positioning block 4 is rotated 90°, the orientation rotation angle of the assembled base 11 and the pin 121 corresponds to 90°. By analogy, different assembly process requirements of the same component can be met.

[0048] It is understandable that the number and position of the positioning holes 41 can be adjusted according to actual design needs. The number of positioning holes 41 is N, and the azimuth rotation angle of the pin 121 after the base 11 and the optical emitting sub-component 12 are assembled is α, then N=2π / N. For example, the azimuth rotation angle between the base 11 and the pin 121 is 18°, and the number of positioning holes 41 is 20. In this way, when assembling the optical transceiver 1, the azimuth rotation angle between the base 11 and the pin 121 can also be 36°, 54°, 72°, 90°, 108°, etc.

[0049] In order to facilitate the determination of the initial placement position of the light emitting sub-component 12, a marking post 36 is fixed around the first positioning block 3 near the through hole 35. The marking post 36 can be a protrusion with a length, width and height of 1 mm each.

[0050] Under this concept, in order to improve the relative rotation angle accuracy of the base 11, the second positioning block 4 may include a rotating part and a fixed part that are rotatably connected, the placement port 42 is located at the center of the rotating part, and the rotating part and the fixed part may be connected by bearing rotation or lubrication rotation. The fixed part is fixedly connected to the base 2, and the fixed part is provided with an angular scale around the central axis, and a pointer is provided on the edge of the rotating part. The fixed part may be threaded radially with a fixing pin that can abut against the circumferential side of the rotating part. When the rotating part rotates to a suitable angle, the fixing pin is tightened to fix the relative position of the rotating part and the fixed part. As needed, a gear transmission mechanism or a worm gear mechanism may also be provided between the rotating part and the fixed part, so that the rotating part can be initially self-locked after rotation.

[0051] In order to prevent the base 11 from being pressed and deformed by the end face of the base 11 located in the mounting hole 111 and the top face of the first positioning block 3 after the light emitting sub-component 12 is installed in the mounting hole 111, a circular boss 34 is provided in the center of the first positioning block 3, and a through hole 35 is opened in the area of ​​the boss 34, and the outer diameter of the boss 34 is less than or equal to the inner diameter of the mounting hole 111.

[0052] In other implementations of the embodiments of the present application, the guide pillar 22 can be set at other positions of the base 2, such as the position between the center and the edge of the base 2, and the number of the guide pillars 22 can also be other numbers, such as 1, 2, 3, 5 or more, which can be selected according to needs. The cross-section of the matching surface of the guide pillar 22 and the guide groove 32 can also be other shapes, such as triangle, rectangle, prism, ellipse, circle, arc, V-shape, W-shape, dovetail groove shape, etc.

[0053] The second positioning block 4 can be fixed to the top of the guide column 22 by bolts. The position fixing method of the first positioning block 3 and the base 2 is specifically as follows: a receiving groove 23 is provided on the top surface of the base 2, a magnet 5 is fixedly placed in the receiving groove 23, a countersunk hole 33 is provided at a corresponding position on a side of the first positioning block 3 close to the base 2, a magnet 5 is also fixed in the countersunk hole 33, the number and position of the countersunk holes 33 correspond to the receiving groove 23, and the magnet 5 in the receiving groove 23 and the magnet 5 in the countersunk hole 33 have the same polarity on the side close to each other, so that the two magnets 5 at the same position generate repulsion, so that the first positioning block 3 can be suspended above the base 2. The magnets 5 on the base 2 and the magnets 5 on the first positioning block 3 can be 4, and the specific number and position can be adjusted according to the size of the required repulsion and the magnetic force of each pair of magnets 5. In this way, when the external force is removed after the pressing operation is completed, the first positioning block 3 can be suspended under the action of magnetic force and automatically rebound and return the material.

[0054] In other embodiments, as required, the first positioning block 3 and the guide column 22 may also be fixed or clamped by screws. An elastic reset member such as a spring may also be provided between the first positioning block 3 and the base 2, and the elastic potential energy of the compressed spring may be used to make the first positioning block 3 rebound and return the material.

[0055] When the distance between the first positioning block 3 and the base 2 is smaller than the length of the pin 121 , a retreat hole 21 may be opened in the middle of the base 2 , and the pin 121 may be inserted into the retreat hole 21 , so that the pin 121 is kept straight during assembly.

[0056] In order to adapt to different depths of the light emitting sub-component 12 inserted into the mounting hole 111 of the base 11 , the thickness of the second positioning block 4 can be designed and adjusted.

[0057] refer to Fig. 9 The base 11 includes a base body 113 and a hole base 112 that are fixedly connected. The mounting hole 111 is provided on the hole base 112. The central axis of the hole base 112 intersects with the central axis of the base body 113. The angle between the two axes is β, which can be 0-30°, specifically selected according to the design requirements of the optical transceiver 1. The angle between the end face of the base 11 away from the mounting hole 111 and the end face of the mounting hole 111 is also β.

[0058] Combination Fig.10 , at this time, the angle between the upper surface of the second positioning block 4 and the horizontal plane is β. In order to adapt to the upper surface of the second positioning block 4, the OSA optical component assembly device also includes a universal damping punch head 6 and a punch connector 7. The punch connector 7 is used to connect an external force-applying device such as a hydraulic cylinder or a cylinder. The universal damping punch head 6 includes a punch head and a universal damping ball joint. The universal damping ball joint is connected between the punch head and the punch connector 7, and the punch head is disc-shaped. In this way, the universal damping ball joint shaft can adaptively flatten the upper surface of the second positioning block 4, and is suitable for riveting angles of different optical transceivers 1.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
