[0039] The rolling assembly includes a frame plate 691 inside the protective shell 681, side plates 692 on both sides of the frame plate 691, a rotating column 693 rotatably connected to one side of the side plates 692, and a roller 694 on the outer side of the rotating column 693.

Two springs 6912 are provided at both ends of the linkage rod 6911 to prevent the probe 65 from deviating. At the same time, the structure has strong linkage, smooth operation, and reduces test failures.

[0040] Working principle: The user opens the cabinet door and removes the slidingly connected placement plate 32 from the inside of the cabinet 1, simultaneously removing the anti-detachment component 5 from the outside of the cabinet 1. The operator then places the optical module workpieces sequentially into the placement slots of the placement plate 32. Since the inner wall of the placement slot is embedded with a storage slot 51, and each storage slot 51 has two sets of inverted V-shaped inclined plates 54 symmetrically connected inside, when the workpiece is placed into the storage slot 51, it will contact and press against the bottom ends of the two sets of inclined plates 54. This causes the two sets of inclined plates 54 to rotate in opposite directions and fit against the side of the workpiece. The inclined plates 54 drive the rotating rod 53 to rotate synchronously. The springs at both ends 55 rotate and store energy. When the workpiece is removed and the inclined plate 54 is no longer squeezed, the springs 55 release their elasticity, causing the rotating rod 53 and the outer inclined plate 54 to rotate and return to their original positions. The operator repeats the above operation to place multiple optical module workpieces into each set of placement slots in the placement plate 32, completing the workpiece loading operation. This achieves rapid positioning and anti-detachment of the optical module workpieces, facilitates the removal and return of the placement plate 32, prevents workpieces from shifting and shaking during aging tests, ensures the accuracy of subsequent tests, simplifies workpiece placement operations, improves loading efficiency, adapts to batch testing needs, and reduces the difficulty of loading for operators.

[0041] After the aging test of the optical module workpiece is completed, the staff drives the electric push rod 57 on one side of the fixed plate 56. The electric push rod 57 drives the linkage block 58 at the output end to move into the placement plate 32. In turn, the linkage block 58 drives the top plate 52 inside the placement plate 32 to move upward. The top plate 52 contacts the bottom of the workpiece and pushes the workpiece out of the placement slot. The staff can then complete the workpiece unloading operation without manually reaching into the box 1 to retrieve the workpiece. This achieves automatic ejection of the workpiece without manual handling. The fixed plate 56 provides fixed support for the electric push rod 57, ensuring the stability of the ejection action, reducing the labor intensity of the staff, avoiding burns caused by the high temperature inside the box 1 during manual handling, improving unloading efficiency, reducing the test cycle, and adapting to the automated testing process.

[0042] After all workpieces are placed, the worker aligns the placement plate 32 with the receiving plate 31 via the bottom sliding plate 33, and slides it along the receiving plate 31 into the interior of the housing 1. After ensuring accurate positioning of the placement plate 32, the housing door is closed. Then, the heating wire 22 inside the bottom plate 21 of the heating plate 2 is activated, simultaneously starting the hot air blower 41 inside the housing 1. The hot air blower 41 transmits heated air to the inside of the air duct 42, which then distributes the hot air to the branch pipes 43. Multiple branch pipes 43 uniformly transmit the hot air to the inside of the air guide box 44. Since the two air guide boxes 44 are interconnected by three branch pipes 43, uniform distribution of hot air is ensured. Finally, the hot air inside the air guide box 44 is evenly blown towards the workpiece through the fan head 45, thus purifying the workpiece. High-temperature aging treatment is performed. A temperature sensor is installed inside the chamber 1 to facilitate real-time monitoring of the internal temperature. Operators can adjust the power of the heating wire 22 and the airflow of the hot air blower 41 based on the monitoring data to ensure that the internal temperature of the chamber 1 is stable at the standard temperature required for the optical module aging test, achieving uniform heating inside the chamber 1. The temperature sensor enables real-time monitoring of the internal temperature of the chamber 1, facilitating temperature adjustment and ensuring that the optical module workpiece is in a stable high-temperature aging environment, simulating the harsh conditions of long-term workpiece operation, and ensuring the authenticity and reliability of the aging test results. Uniform heating can avoid local overheating or insufficient temperature of the workpiece, improve the consistency of batch testing, and adapt to the aging temperature requirements of different models of optical modules through the temperature adjustment function.

[0043] To prevent the probes 65 from creeping and losing elasticity under high-temperature aging conditions, which could lead to poor contact and distorted test data, an anti-creep component 68 is installed on the outside of each group of probes 65. When the chamber 1 enters a high-temperature aging state, the probes 65 are insulated by the anti-creep component 68, reducing the impact of high temperature on the probes 65. At the same time, a positioning component 69 is installed inside the anti-creep component 68 to radially position the probes 65, preventing them from shifting or bending, ensuring the structural integrity and positional accuracy of the probes 65, and laying the foundation for subsequent testing. The anti-creep component 68 provides thermal insulation protection for the probes 65, reducing damage from high temperature; the positioning component 69 radially positions the probes 65, preventing them from shifting or bending, extending their service life, preventing increased contact resistance and test data drift due to high-temperature creep, ensuring the test stability of the probes 65, and guaranteeing test accuracy.

[0044] When the optical module needs to undergo aging testing, the anti-creep component 68 and positioning component 69 need to be disengaged from the probe 65. The operator activates the hydraulic rod 66 on one side of the horizontal connecting plate 61. The hydraulic rod 66 drives the connecting block 610 at the output end to slide outwards towards the housing 63, thereby causing the connecting block 610 to move the protective shell 681 upwards synchronously. During the movement of the protective shell 681, it slides inside the circular groove 64. The bottom end of the probe 65 first contacts the cleaning ring 685. The cleaning ring 685 is made of flexible, wear-resistant material, which can effectively remove dust and oxide layers from the surface of the probe 65, preventing the oxide layer from increasing the contact resistance and ensuring the contact stability between the probe 65 and the gold fingers. As the protective shell 681 continues to move upwards, the bottom end of the probe 65 compresses the conical shell 683. After being compressed, the conical shell 683 rotates outwards and opens through the hinge 682. The top of the conical shell 683 is equipped with a rubber strip 684, which connects to the bottom of the protective shell 681. The end contact effectively buffers the rigid contact between the bottom of the conical shell 683 and the protective shell 681, preventing wear on both and extending the service life of the components. After the conical shell 683 opens, the probe 65 continues to extend downward. At this time, the ball bearing 6914 of the positioning component 69 rolls into contact with the surface of the probe 65, providing auxiliary guidance for the probe 65 and ensuring that the probe 65 moves vertically downward, realizing the up-and-down movement of the protective shell 681 and completing the separation and attachment of the anti-creep component 68 and the probe 65. The cleaning ring 685 removes impurities and oxide layers from the surface of the probe 65. The opening and closing of the conical shell 683 is achieved through the hinge 682, and the rubber strip 684 provides buffer protection. The ball bearing 6914 provides auxiliary guidance for the probe 65, ensuring the surface of the probe 65 is clean, avoiding poor contact, and improving test accuracy. Buffer protection reduces component wear and extends the overall service life of the device. Auxiliary guidance ensures that the probe 65 is accurately aligned with the gold fingers of the optical module, avoiding misalignment that could lead to test failure.

[0045] As the protective shell 681 continues to move upward, the roller 694 contacts the surface of the probe 65 and rolls in the opposite direction. The roller 694 drives the rotating column 693 to rotate in the opposite direction. The rotating column 693 is connected to the frame plate 691 through the measuring plate 692 connected to both sides. The frame plate 691 is fixedly connected to the protective shell 681 to ensure the stability of the rotating column 693 during rotation. When the rotating column 693 rotates, it drives the bevel gear set 696 to rotate in the opposite direction. The bevel gear set 696 drives the lead screw 697 to rotate in the opposite direction synchronously. The lead screw 697 is connected to the sleeve 698 by a reverse thread, causing the sleeve 698 to move towards the rectangular frame 695. The sleeve 698 slides in the opposite direction with the long rod 699 and moves closer to the rectangular frame 695. At this time, the sleeve 698 no longer pushes the bottom end of the rotating plate 6910. The rotating plate 6910 is connected to the spring 6912 at both ends of the linkage rod 6911. The spring force is released, rotating the plate 6910 from an oblique position to a vertical position. The rotating plate 6910 moves the arc plate 6913 and the ball bearing 6914 away from the surface of the probe 65, completely releasing the positioning constraint on the probe 65. This allows the probe 65 to completely detach from the interior of the protective shell 681 and smoothly contact the gold fingers of the optical module workpiece, achieving a state switch for the rotating plate 6910. The automatic reset of the rotating plate 6910 is achieved through the cooperation of the linkage rod 6911 and the second spring 6912. The positioning and release of the probe 65 are achieved through the arc plate 6913 and the ball bearing 6914, enabling the automatic disengagement of the positioning component 69 from the probe 65 without manual intervention, thus improving the automation level of the test. The automatic reset function ensures stable positioning of the probe 65 by the positioning component 69 in non-testing states, preventing probe 65 from shifting. Simultaneously, the strong structural linkage ensures smooth operation and reduces test failures.

[0046] After probe 65 is completely detached from protective shell 681, the operator activates cylinder 62 at the bottom of horizontal connecting plate 61. Cylinder 62 moves shell 63 downward, which in turn moves probe 65 downward until probe 65 is precisely aligned with the gold fingers of the optical module workpiece and achieves elastic electrical contact. Probe 65 provides stable power to the optical module workpiece through the gold fingers, while simultaneously collecting the optical module's operating voltage, current, temperature, and communication signals in real time and transmitting them to an external control terminal. The operator monitors the aging status of the optical module in real time through the control terminal to determine if there are any performance abnormalities. During the test, the interior of enclosure 1 is kept at a high temperature to simulate the high-temperature environment of long-term optical module operation, completing the aging test of the optical module. Cylinder 62 moves shell 63 and probe 65 up and down to achieve precise contact between probe 65 and gold fingers. Probe 65 enables power supply to the optical module and test data acquisition, ensuring the stability of the contact between probe 65 and gold fingers and avoiding data distortion due to poor contact. Real-time acquisition of test data allows the operator to promptly grasp the aging status of the optical module, improving testing efficiency and accuracy, and adapting to the needs of automated batch testing.

[0047] Conversely, when probe 65 is not being tested, the operator closes cylinder 62, which moves housing 63 and probe 65 upwards to reset. Then, hydraulic rod 66 is activated, moving connecting block 610 and protective shell 681 downwards until the protective shell 681 is fitted over probe 65, providing heat insulation and dust protection. Simultaneously, positioning component 69 automatically resets, radially positioning probe 65 to prevent bending or damage from external impacts. The reset of probe 65 is achieved through cylinder 62; the reset of protective shell 681 through hydraulic rod 66, providing protection for probe 65; and the stable positioning of probe 65 through the automatic reset of positioning component 69. This comprehensive protection extends probe 65's lifespan, prevents damage during non-testing periods, reduces device maintenance costs, and ensures smooth operation of subsequent tests.

[0048] During the downward movement of the protective shell 681 and the upward repositioning of the conical shell 683, the conical shell 683 drives the hinge 682 to rotate. The gear 676 on the outer side of the rotating rod of the hinge 682 rotates synchronously. At this time, the second wedge block 672 is pressed by the inclined surface of the first wedge block 671 and moves into the interior of the long shell 673. The second wedge block 672 drives the side blocks 675 on both sides to move towards the hinge 682. The side blocks 675 cause the spring inside the long shell 673 to stretch and store force. The second wedge block 672 gradually moves out of the outer side of the long shell 673, opening one side of the long shell 673 to facilitate its movement. Simultaneously, the second wedge block 672 drives the rack 674 on one side to move synchronously. The rack 674 meshes with the gear 676, driving the gear... The rotation of 676 and hinge 682 causes the conical shell 683 to expand outward, preventing it from obstructing the probe 65 and ensuring that the subsequent contact between the probe 65 and the gold fingers of the optical module workpiece is not affected. This ensures that the aging test can proceed normally. Through the cooperation of wedge block 1 671, wedge block 2 672, long shell 673, rack 674, side block 675, and gear 676 in the expansion component 67, the conical shell 683 can automatically expand and open. Through the tension and storage of the spring, wedge block 2 672 can automatically reset, preventing the conical shell 683 from obstructing the probe 65 and ensuring normal contact between the probe 65 and the gold fingers, thus ensuring the smooth progress of the test. The automatic expansion and reset functions do not require manual intervention, improving the automation level of the device and simplifying the operation process.
