Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 2, fig. 3a, fig. 3b, fig. 4 and fig. 5, a method for manufacturing a COB optical module according to an embodiment of the present invention includes the following steps: s1, assembling the ROSA adapter 10, the TOSA adapter 11, the optical engine 12, and the PCBA board 13 together to obtain the COB assembly 1, wherein the ROSA adapter 10 is movable; s2, after the COB assembly 1 is assembled, adjusting the position of the LC optical port 2; s3, after the position of the LC optical port 2 is adjusted, the TOSA adapter 11 and the movable ROSA adapter 10 are mounted on the LC optical port 2; s4, after the installation is finished, the integral structure formed by the LC optical port 2 and the COB assembly 1 is installed in a base 3 for fixation; in the step S3, the LC optical port 2 whose position is adjusted may be such that the distance D1 between the flanges 111 of the ROSA adapter 10 and the TOSA adapter 11 and the positioning hole 130 of the PCBA board 13 matches the distance D2 between the flanges 111 of the ROSA adapter 10 and the TOSA adapter 11 and the PCB positioning post of the base 3, which are located on the LC optical port 2. In the conventional COB optical module, the LC optical port 2 is usually fixed to the chassis 3, where the distance between the two positions is defined as D1, the fluctuation range of the dimension D1 is large due to the coupling tolerance of the device and the PCBA attachment error, and the dimension D1 of each COB assembly 1 is not the same, but once the LC optical port 2 and the chassis 3 are fixed together in advance, the dimension D2 between the ROSA adapter 10 and the TOSA adapter 11 and the PCB positioning column of the chassis 3 is a fixed value (as shown in fig. 1), and the dimension D1 has a large error, so that the dimension D1 and the dimension D2 cannot be completely matched. In the present embodiment, to solve this problem, we first separate the LC optical port 2 from the base 3 during the manufacturing process, so that the size of D1 can be adjusted. In the embodiment, the ROSA adapter 10 is movable because it is flexibly connected by the optical fiber, but the relative position of the optical port needs to be fixed, so that the optical fiber can be inserted and pulled in the optical module without light falling, and the problem can be solved by using the movable LC optical port 2.
Referring to fig. 2, 3a, 3b, 4, 5, 6, 7a and 7b as an optimized solution of the embodiment of the present invention, in the step S3, the movable ROSA adapter 10 is locked on the LC optical port 2 by a locking assembly detachably mounted on the LC optical port 2, and the locking assembly is mounted after the position of the LC optical port 2 is adjusted. In contrast to the integrated form of the LC optical port 2 of the prior art, the flange 111 of the ROSA adapter 10 cannot be inserted into the LC optical port 2, so that in this embodiment a separate component, namely a locking assembly, is used for additional locking, and since this locking assembly is detachably connected to the LC optical port 2, it can be adjusted in position to ensure dimensional matching before final adhesive attachment.

In the embodiment, a specific locking mode is a pressing block 4 and a screw 5, and locking can be completed by pressing down the pressing block 4 and then screwing the pressing block 4 into a corresponding threaded hole of the LC optical port 2 through the screw 5.

In order to further optimize the above solution, referring to fig. 6, fig. 7a, and fig. 7b, the first card slot 20 and the second card slot 40 have a limiting surface 400 for limiting the ROSA adapter 10 to come out at a side close to the electrical port of the optical module. In this embodiment, the surfaces of the first and second card slots 20 and 40 facing the electrical port are limiting surfaces 400, which can prevent the ROSA adapter 10 from falling out.
As shown in fig. 6, fig. 7a and fig. 7b, the pressing block 4 and the LC optical port 2 are further refined, and a protruding rib 41 capable of being snapped into the groove 21 of the LC optical port 2 is further provided on a side of the pressing block 4 facing the ROSA adapter 10. In this embodiment, to ensure a more stable assembly, the engagement of rib 41 into groove 21 may be used to limit movement in other possible orientations.

In the conventional COB optical module, the LC optical port 2 is usually fixed to the chassis 3, where the distance between the two positions is defined as D1, the fluctuation range of the dimension D1 is large due to the coupling tolerance of the device and the PCBA attachment error, and the dimension D1 of each COB assembly 1 is not the same, but once the LC optical port 2 and the chassis 3 are fixed together in advance, the dimension D2 between the ROSA adapter 10 and the TOSA adapter 11 and the PCB positioning column of the chassis 3 is a fixed value (as shown in fig. 1), and the dimension D1 has a large error, so that the dimension D1 and the dimension D2 cannot be completely matched. In the present embodiment, to solve this problem, we first separate the LC optical port 2 from the base 3 during the manufacturing process, so that the size of D1 can be adjusted. In the embodiment, the ROSA adapter 10 is movable because it is flexibly connected by the optical fiber, but the relative position of the optical port needs to be fixed, so that the optical fiber can be inserted and pulled in the optical module without light falling, and the problem can be solved by using the movable LC optical port 2.

In contrast to the integrated form of the LC optical port 2 of the prior art, the flange 111 of the ROSA adapter 10 cannot be inserted into the LC optical port 2, so that in this embodiment a separate component, namely a locking assembly, is used for additional locking, and since this locking assembly is detachably connected to the LC optical port 2, it can be adjusted in position to ensure dimensional matching before final adhesive attachment. The specific locking mode is that a pressing block 4 and a screw 5 are adopted, and locking can be completed by pressing down the pressing block 4 and then screwing the pressing block 4 into a corresponding threaded hole of the LC light port 2 through the screw 5. Of course, in addition to this locking, other locking means are also possible, such as snap-in, magnetic, etc. Preferably, set up the confession on the LC optical port 2 the first draw-in groove 20 that the ring flange 111 of ROSA adapter 10 was gone into, briquetting 4 orientation one side of ROSA adapter 10 sets up the confession the second draw-in groove 40 that the ring flange 111 of ROSA adapter 10 was gone into, adopts first draw-in groove 20 with second draw-in groove 40 will ROSA adapter 10 is fixed, specifically, sets up first draw-in groove 20 on LC optical port 2, can supply ROSA adapter 10's ring flange 111 to go into, and the same position that corresponds at briquetting 4 sets up second draw-in groove 40, and first draw-in groove 20 and second draw-in groove 40 enclose and close the cell body structure that can block ROSA adapter 10's ring flange 111, and here because TOSA adapter 11 is fixed, it can not need the card of draw-in groove, of course can set up, can play better fixed effect after setting.
