Description

Technical Field

[0001] The utility model relates to the technical field of optical module vibration testing, and in particular to an optical module mechanical vibration testing device. Background Art

[0002] The purpose of optical module vibration testing is to evaluate the optical module's ability to resist vibration during transportation and use, ensuring its reliability and stability. During the optical module vibration test, how to quickly clamp the optical module body and how to quickly rotate the optical module according to the vibration test direction are currently urgent issues to be solved.

[0003] After searching, the announcement number CN220751540U discloses a vibration testing device for an optical module, which includes a vibration chassis, two side plates vertically installed on the top of the vibration chassis, and the two side plates are symmetrically distributed on the left and right of the top of the vibration chassis. A frame is installed at the middle position between the two side plates, and a mounting plate is installed between the frames. A plurality of mounting slots are evenly provided on the mounting plate, two first screw grooves are provided at both ends of the mounting plate, and two first screw holes are provided at both ends of the frame. This utility model can fix the frame between the two side plates or at the same end of the two side plates by using a second bolt, so that the frame and the mounting plate are respectively in a horizontal state and a vertical state, and then the vibration chassis is controlled to vibrate to detect the stability of the installation between the optical module and the mounting plate, and the mounting plates with mounting slots of different sizes can be replaced by a third bolt to test optical modules of different models.

[0004] The vibration testing device for the above-mentioned optical module requires individually tightening the bolts to replace the mounting plate when testing optical modules of different sizes. At the same time, when switching between horizontal and vertical state tests, the mounting plate also needs to be tightened in sequence to complete the disassembly and assembly between the side panel and the frame. The above two sets of design defects will cause the vibration testing process to take a long time. Utility Model Content

[0066] A steering assembly 3 is provided at the connection between the side supports 11 and the placement platform 4 and is capable of driving the placement platform 4 to rotate between the two sets of side supports 11;

[0067] This design solves the problem in the existing technology that when testing optical modules of different sizes, it is necessary to individually tighten the bolts to replace the mounting plate. At the same time, when switching between horizontal and vertical state tests, the mounting plate also needs to be disassembled and assembled between the side panel and the frame by tightening each bolt in sequence. The above two sets of design defects will cause the vibration test process to take a long time.

[0079] See also Figure 2 and Figure 3 , the clamping assembly 5 further includes:

[0080] an anti-slip layer 531 fixedly connected to the other side of the clamping plate 53;

[0081] After the optical module to be tested for vibration is placed on top of the placement table 4, the forward and reverse motor 51 located on the side of the clamping assembly 5 can be started. The forward and reverse motor 51 can drive the bidirectional threaded rod 511 to rotate in the rail groove 41, thereby causing the slide 52 threadedly connected to the opposite threads on both sides of the bidirectional threaded rod 511 to drive the clamping plates 53 to move toward each other synchronously, and then the clamping work of the optical module is completed under the cooperation of the two sets of clamping plates 53;

[0082] In particular, the present design provides an anti-slip layer 531 on one side of the clamping plate 53 to increase the clamping friction and prevent the optical module from loosening.

Specifically, the cylinder 36 can be started so that the output end of the cylinder 36 drives the reinforcement support plate 35 and the base frame 34 to move up and down, thereby causing the side frames 33 and the gear holder 32 on both sides of the base frame 34 to move up and down synchronously. At this time, the side tooth groove group 321 of the gear holder 32 can engage and drive the gear disc 311 to rotate. At this time, the gear disc 311 will drive the placement table 4 to turn quickly through the rotating rod 31;

[0105] In particular, after the above-mentioned placement table 4 and the optical module clamped on the top of the placement table 4 are fixed, the supporting base 1 and the placement table 4 set above the supporting base 1 and the optical module clamped on the top of the placement table 4 can be driven by the vibration chassis mechanism 2 to perform a vibration test.
