Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jigs, in particular to an optical module coupling test jig. Background Technique
[0002] After the production of the optical module is completed, coupling test is required. Coupling test is an important test method in software testing. It is mainly used to test whether the data interaction and information transmission between various modules of the system are normal, and whether the integration between different subsystems is smooth.
[0003] At present, the test of the optical module after production is carried out by installing the optical module on the PCB board in sequence. However, there is a lack of a fixing jig corresponding to the PCB board on the market. The common method is to directly dock the PCB board and the optical module. This method is easy to damage the PCB board. Therefore, an optical module coupling test jig is proposed to solve the above problems. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an optical module coupling test jig to overcome the deficiencies in the above-mentioned prior art.
[0005] The technical solution of the utility model to solve the above technical problems is as follows: It includes a bottom frame. A top frame is fixedly installed on the top of the bottom frame. Four support plates located inside the top frame are fixedly installed on the top of the bottom frame. A PCB board passing through to its interior is movably installed on the top of the four support plates. A test interface is arranged on the top of the PCB board. Two lifting frames passing through to the interior of the bottom frame are slidably installed on the top of the top frame. The two lifting frames are respectively located inside the left and right side walls of the top frame and the bottom frame. A cross bar located inside the bottom frame is fixedly installed between the two lifting frames. A threaded rod passing through to the interior of the cross bar is rotatably installed inside the bottom frame. The threaded rod is in threaded connection with the cross bar. A driven gear located near its bottom is fixedly installed on the outside of the threaded rod. A driving motor is fixedly installed on the bottom of the inner cavity of the bottom frame. A start switch electrically connected to the driving motor is fixedly installed on the top of the top frame. A gear meshing with the driven gear is fixedly installed at the output end of the driving motor. A limiting slide bar passing through to its bottom is slidably installed on the top of each of the two lifting frames. A pressing plate located on the top of the PCB board is fixedly installed at the bottom of each of the two limiting slide bars. Springs sleeved on the outside of the limiting slide bars are fixedly installed on the top of each of the two pressing plates.
[0006] The beneficial effect of the utility model is that by driving the driven gear to rotate forward by the driving motor, the cross bar can be forced to drive the two lifting frames to descend. When the two lifting frames descend and drive the two pressing plates to fall, the PCB board can be squeezed and fixed. After the PCB board is fixed, the produced optical modules can be docked and tested with the test interface in sequence. At this time, the damage rate of the PCB board can be significantly reduced.
[0007] On the basis of the above technical solution, the present utility model can also be improved as follows.
[0008] Furthermore, thrust frames are fixedly installed at the tops of the two lifting frames, pressure sensors penetrating to the bottoms are fixedly installed at the tops of the two thrust frames, the two pressure sensors are respectively located at the tops of the two limiting sliding rods, a controller electrically connected to the two pressure sensors is fixedly installed on the surface of the gear, and the controller is electrically connected to the driving motor.
[0009] Furthermore, the four support plates are respectively close to the left and right sides of the PCB board, and rubber pads are fixedly installed at the tops of the four support plates.
[0010] Furthermore, a support plate is fixedly installed on the right side of the top frame, and the support plate is located below the test interface.
[0011] Furthermore, the driving motor is located in front of the cross bar.
[0012] Furthermore, a groove is formed at the top of the top frame, and the groove is located behind the test interface. Description of the Drawings

Detailed implementation mode
[0020] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.
[0021] Embodiment 1, an optical module coupling test fixture, including a bottom frame 1, a top frame 2 is fixedly installed on the top of the bottom frame 1, four support plates 3 located inside the top frame 2 are fixedly installed on the top of the bottom frame 1, a PCB board 4 penetrating into its interior is movably installed on the top of the four support plates 3, a test interface 401 is arranged on the top of the PCB board 4, two lifting frames 5 penetrating into the interior of the bottom frame 1 are slidably installed on the top of the top frame 2, the two lifting frames 5 are respectively located inside the left and right side walls of the top frame 2 and the bottom frame 1, a cross bar 6 located inside the bottom frame 1 is fixedly installed between the two lifting frames 5, a threaded rod 7 penetrating into the interior of the cross bar 6 is rotatably installed inside the bottom frame 1, the threaded rod 7 is in threaded connection with the cross bar 6, a driven gear 8 is fixedly installed on the outside of the threaded rod 7 near its bottom, a driving motor 9 is fixedly installed on the bottom of the inner cavity of the bottom frame 1, a start switch 201 electrically connected to the driving motor 9 is fixedly installed on the top of the top frame 2, an output end of the driving motor 9 is fixedly installed with a gear 10 meshing with the driven gear 8, a limiting slide bar 11 penetrating to the bottom is slidably installed on the top of each of the two lifting frames 5, a pressing plate 12 located on the top of the PCB board 4 is fixedly installed at the bottom of each of the two limiting slide bars 11, and a spring 13 sleeved on the outside of the limiting slide bar 11 is fixedly installed on the top of each of the two pressing plates 12.
[0022] When in use, first insert the PCB board 4 into the interior of the top frame 2 and the four support plates 3 from front to back, and then press the start switch 201 to control the driving motor 9 to start. The driving motor 9 starts to drive the gear 10 to rotate forward, and the gear 10 drives the driven gear 8 and the threaded rod 7 to rotate synchronously. At this time, when the threaded rod 7 rotates forward, it can force the cross bar 6 to drive the two lifting frames 5 to descend. The two lifting frames 5 descending can drive the two limiting slide bars 11 and the pressing plates 12 to fall. When the two pressing plates 12 contact the top of the PCB board 4, it can be squeezed and fixed. After the PCB board 4 is fixed, the produced optical modules can be docked and tested with the test interface 401 in turn. At this time, the damage rate of the PCB board 4 can be significantly reduced. When the PCB board 4 needs to be replaced, the driving motor 9 can be controlled to drive the threaded rod 7 to rotate reversely. When the threaded rod 7 rotates reversely, it can drive the pressing plates 12 on the two lifting frames 5 to rise. At this time, the top of the PCB board 4 loses the restriction and can be taken out.
[0023] Embodiment 2, this embodiment is a further improvement based on Embodiment 1, and the specific content is as follows:
[0024] At the top of both lifting frames 5, thrust frames 14 are fixedly installed. At the top of both thrust frames 14, pressure sensors 15 penetrating to their bottoms are fixedly installed. The two pressure sensors 15 are respectively located at the tops of the two limit slide bars 11. On the surface of the gear 10, a controller 16 electrically connected to the two pressure sensors 15 is fixedly installed. The controller 16 is electrically connected to the drive motor 9.
[0025] When the two lifting frames 5 drive the two pressing plates 12 to descend and contact the top of the PCB board 4, a reaction force will be generated to push the limit slide bars 11 to rise, and the two springs 13 will contract until the two pressure sensors 15 transmit the impact signal of the limit slide bars 11 to the drive motor 9. At this time, the drive motor 9 will stop operating, and at this time, the two lifting frames 5 will not drive the two pressing plates 12 to descend, thereby preventing the PCB board 4 from being violently pressed. Finally, when the two lifting frames 5 rise, the two springs 13 will expand to push the pressing plates 12 and the limit slide bars 11 to reset.

[0027] The four support plates 3 are respectively close to the left and right sides of the PCB board 4, and rubber pads 17 are fixedly installed on the tops of the four support plates 3.
[0028] The two installed rubber pads 17 can play a protective role when contacting the bottom of the PCB board 4.
[0029] Embodiment 4, this embodiment is a further improvement based on Embodiment 1, and the specific content is as follows:
[0030] A support plate 18 is fixedly installed on the right side of the top frame 2, and the support plate 18 is located below the test interface 401.
[0031] The installed support plate 18 can support the bottom of the PCB board 4 to prevent the PCB board 4 from bending when pressing the test interface 401.
[0032] Embodiment 5, this embodiment is a further improvement based on Embodiment 1, and the specific content is as follows:
[0033] The drive motor 9 is located in front of the cross bar 6 to prevent the cross bar 6 from descending and colliding with the drive motor 9.
