[0002] Optical communication modules are core components in modern communications, playing a crucial role in converting electrical signals to optical signals in scenarios such as 5G base stations and data centers. Their performance directly determines network transmission quality. As the core node of optical networks, optical communication modules enable bidirectional conversion between electrical and optical signals, supporting high-speed data transmission for technologies such as 5G and cloud computing. Their stability and reliability directly impact the operational efficiency of the entire communication system.

[0003] The performance parameters of an optical communication module include optical performance parameters, electrical performance parameters, and transmission performance parameters.

Simple equipment has limited testing capabilities, failing to comprehensively cover optical, electrical, and transmission performance parameters, and lacks sufficient accuracy to meet the demands of high-requirement scenarios. The absence of automated testing lines results in fragmented testing processes, hindering production efficiency and compromising consistency in testing standards, causing product performance fluctuations, increasing production costs, and restricting large-scale production. With the widespread adoption of 5G and cloud computing technologies, market demands for the speed and stability of optical communication modules continue to rise, placing higher standards on the comprehensiveness, accuracy, and efficiency of testing. The lack of automated testing lines makes it difficult for the efficiency and accuracy of the testing process to meet industry development needs, becoming a core bottleneck restricting the large-scale production and performance upgrades of optical communication modules.

[0023] This invention provides an automated testing line for optical communication modules, such as... Figures 1 to 13 As shown, including At least one pre-inspection loading platform 10 is used to carry the optical communication module 40 before inspection; At least one post-inspection loading platform 20 is used to carry the optical communication module 40 after inspection; The testing platform 30 is used to support the optical communication module 40 to be tested, and the surface temperature of the testing platform 30 is maintained within a preset constant temperature range. The inspection loading and unloading system 50 is used to send the optical communication module 40 on the pre-inspection loading platform 10 to the inspection platform 30, or to send the optical communication module 40 on the inspection platform 30 to the post-inspection loading platform 20. Electrical performance testing system 60 is used to test the electrical performance of optical communication module 40; Optical performance testing system 70 is used to test the optical performance of optical communication module 40.

[0024] Before testing, the optical communication module 40 is manually placed onto the pre-test loading platform 10. The testing loading and unloading system 50 then transfers the optical communication module 40 from the pre-test loading platform 10 to the testing platform 30. The electrical performance testing system 60 and the optical performance testing system 70 then test the optical communication module 40 on the testing platform 30. After testing, the testing loading and unloading system 50 transfers the optical communication module 40 from the testing platform 30 to the post-test loading platform 20. This completes the automated feeding and unloading process of the optical communication module 40. The process is highly automated, fast, and efficient, and can comprehensively test both the electrical and optical performance of the optical communication module 40.

[0025] Furthermore, in some embodiments of this invention application, such as Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, both the pre-inspection loading platform 10 and the post-inspection loading platform 20 are equipped with tooling tables 80 for placing optical communication module trays 90, with the optical communication module trays 90 embedded in the tooling tables 80. The testing platform 30 is equipped with testing fixtures for placing optical communication modules 40.

[0026] Before testing, the optical communication module tray 90 containing the optical communication module 40 is manually placed on the tooling table 80 of the pre-test loading table 10, and the optical communication module tray 90 without workpieces is placed on the tooling table 80 of the post-test loading table 20. The testing loading and unloading system 50 picks up a single optical communication module 40 from the optical communication module tray 90 and sends it to the testing table 30, and then sends the single optical communication module 40 that has completed testing on the testing table 30 to the optical communication module tray 90 of the post-test loading table 20.

[0027] If the ambient temperature is unstable, the test results of the same module will vary significantly under different temperatures. Temperature fluctuations will lead to inconsistent test standards for different modules, making it impossible to accurately determine product consistency and affecting subsequent production screening and quality control. Therefore, in some embodiments of this invention, a copper tube electric heating element heater is provided inside the testing platform 30 to heat the surface of the testing platform 30; a cooling fan is provided at the bottom of the testing platform 30; and a temperature control detection unit is provided inside the testing platform 30 to detect the temperature of the surface of the testing platform 30. The temperature control detection unit is electrically connected to the copper tube electric heating element heater and the cooling fan to control the surface temperature and maintain it within a preset constant temperature range.

[0028] Furthermore, in some embodiments of this invention application, such as Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, the detection loading and unloading system 50 includes a first rail base 51 and a second rail base 52 disposed on the first rail base 51. In a top view, the second rail base 52 is perpendicular to the first rail base 51. The first rail base 51 extends from one side of the pre-inspection loading platform 10 and the post-inspection loading platform 20 to one side of the detection platform 30. The second rail base 52 can move on the first rail base 51. A first sliding frame 53 is provided on the second rail base 52, and the first sliding frame 53 can move on the second rail base 52.

The feeding suction frame 56 can move vertically up and down on the second sliding back frame 55. A suction nozzle 57 is provided on the feeding suction frame 56. The suction nozzle 57 is used to adsorb the optical communication module 40 on the pre-inspection loading platform 10 and send it to the inspection platform 30, or adsorb the optical communication module 40 on the inspection platform 30 and send it to the post-inspection loading platform 20.

[0029] Here, the cooperation of the first rail base 51 and the second rail base 52, and the cooperation of the second rail base 52 and the first sliding frame base 53, establish the X and Y axis movement directions. The cooperation of the first sliding back frame 54 and the second sliding back frame 55 establishes the Z axis movement direction (i.e., the vertical direction). Driven by the three-axis movement, the loading adsorption frame 56 moves towards the pre-inspection loading platform 10, the inspection platform 30, or the post-inspection loading platform 20. The loading adsorption frame 56 can move vertically on the second sliding back frame 55 to approach the pre-inspection loading platform 10 or the inspection platform 30 to adsorb the optical communication module 40, or approach the inspection platform 30 or the post-inspection loading platform 20 to lower the adsorbed optical communication module 40.

A visual alignment device 643 is disposed on the alignment bracket 641. The second drive cylinder 642 can drive the alignment bracket 641 to move vertically downward on the top extension bracket 64 to align with the optical communication module 40 on the testing platform 30, or to rise and reset. A horizontal frame 65 and a third drive cylinder 66 are provided at the lower front end of the second sliding frame 62. The third drive cylinder 66 can drive the horizontal frame 65 to move vertically up and down on the second sliding frame 63. An outward arm 67 is provided at both ends of the horizontal frame 65. A probe card detection module 671 and a transmission performance detection module 672 are provided at the outer ends of the two outward arms 67, respectively. When the horizontal frame 65 is in the lowered state, the probe card detection module 671 approaches the optical communication module 40 on the detection platform 30 and docks with it in the vertical direction. When the horizontal frame 65 is in the lowered state, the transmission performance detection module 672 approaches the optical communication module 40 on the detection platform 30 and docks with it in the lateral direction. A laser alignment module 673 is also provided at the outer ends of the two outward arms 67.

[0032] Here, the third rail base 61 and the fourth rail base 62 cooperate to form two movement directions, X and Y, and the fourth rail base 62 cooperates with the second sliding bracket 63. The alignment bracket 641 and the second drive cylinder 652 cooperate to form the first Z-axis movement direction (i.e., the vertical direction). The visual alignment device 643 completes the visual alignment action under the drive of the three-axis movement. The horizontal bracket 65 and the third drive cylinder 66 cooperate to form the second Z-axis movement direction. The probe card detection module 671 and the transmission performance detection module 672 complete the docking with the optical communication module 40 under the drive of the three-axis movement to perform electrical performance detection and transmission performance detection. The laser alignment module 673 also completes laser alignment under the drive of this three-axis movement.

[0033] Furthermore, in some embodiments of this invention application, such as Figure 1 , 2 As shown in 3, 11, 12, and 13, the optical performance testing system 70 includes a testing fiber optic module. The testing fiber optic module moves in three axes toward the optical communication module 40 supported on the testing stage 30 to test the optical performance of the optical communication module 40, or moves to reset.

[0034] The optical performance testing system 70 includes a fifth rail base 71 and a sixth rail base 72 disposed on the fifth rail base 71. In a top view, the sixth rail base 72 is perpendicular to the fifth rail base 71.

Driven by the three-axis movement, the forward-extending detection frame 77 moves closer to or away from the optical communication module 40. When it moves closer, the detection fiber optic module 78 set on the forward-extending detection frame 77 is attached to the optical communication module 40 and performs optical performance detection on it.
