[0064] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0066] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0067] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0068] The production process of optical modules usually requires laser power and device temperature testing. During this process, the optical module needs to be operated into the test system and the test water and test circuits need to be connected to the optical module. However, after the test of an optical module is completed, the operator needs to cut off the water and power to the optical module and replace the optical module to be tested to connect the water and power. This process is usually time-consuming, causing the execution components of the test system to also spend a long time waiting, resulting in low test efficiency of the test system.

[0069] In view of this, the present invention proposes an optical module testing system, which aims to alleviate the problem that the waiting time of the execution components in the existing optical module testing system is long, resulting in low testing efficiency of the testing system.

[0071] See also Figure 1 and Figure 2 In one embodiment of the present invention, the optical module testing system 1000 includes an operating platform 100, a plurality of circuit sockets 300, a plurality of water sockets 200, and a test execution component 600. The operating platform 100 is formed with a plurality of test stations 11, and the test stations 11 are used to place the optical modules 2000; the plurality of circuit sockets 300 are respectively arranged on the operating platform 100 corresponding to the plurality of test stations 11, and the circuit sockets 300 are used to connect to the working circuit of the optical module 2000 for power supply; the plurality of water sockets 200 are respectively arranged on the operating platform 100 corresponding to the plurality of test stations 11, and the water sockets 200 are used to connect to the cooling water channel of the optical module 2000 for water supply; the test execution component 600 is arranged on the operating platform 100 and has a temperature testing part 62 and a power testing part 63 that can switch between the plurality of test stations 11.

[0072] Among them, the function of the circuit socket 300 is to connect the working circuit of the light module 2000 to form a power supply circuit. Similarly, the function of the water socket 200 is to connect the cooling water path of the light module 2000 to form a water supply circuit. This embodiment does not limit the specific structure of the circuit socket 300 and the water socket 200; the temperature testing part 62 in the test execution component 600 is used to measure the working temperature of the light module 2000 and components such as the combiner, and the power testing part 63 is used to test the output power of the light module 2000. The specific structures of the temperature testing part 62 and the power testing part 63 have various forms. At the same time, there are various ways to switch between multiple test stations 11, such as synchronous switching or step-by-step switching. This embodiment does not limit this.

[0073] The number of test stations 11 to be set depends on the test rhythm of the test execution component 600. For example, when the test rhythm of the test execution component 600 is slow, while the test execution component 600 is testing the optical module 2000 at one of the test stations 11, the operator is already able to complete the plugging and unplugging operations of the water channels and circuits for the optical modules 2000 at other test stations 11. At this time, only two test stations 11 need to be set to match the test efficiency of the test execution component 600. However, when the test rhythm of the test execution component 600 is fast, three or even more test stations 11 may need to be set to match the test efficiency of the test execution component 600.

[0074] The technical solution provided by the present invention is to set up multiple test stations 11, each test station 11 is equipped with a circuit socket 300 and a water socket 200, and at the same time, the temperature testing part 62 and the power testing part 63 of the test execution component 600 can switch positions between multiple test stations 11. In this way, when the temperature testing part 62 and the power testing part 63 test the optical module 2000 in one of the test stations 11, the operator can perform plug-in and unplug-out operations on the water circuits and circuits of the optical modules 2000 in other stations. After the temperature testing part 62 and the power testing part 63 complete the test of the optical module 2000 in one of the test stations 11, they can switch to the next test station 11 for testing operations without wasting time waiting, thereby greatly improving the testing efficiency of the optical module testing system 1000.

[0075] See also Figure 2 In some embodiments, the test execution component 600 includes a two-axis motion module 61 installed on the work platform 100, the two-axis motion module 61 has a drive seat, and the movable travel of the drive seat covers multiple test stations 11; the temperature testing part 62 is installed on the drive seat.

[0076] Among them, the specific structural form of the two-axis motion module 61 is not described in detail in this embodiment. Generally speaking, multiple test stations 11 are in the same horizontal plane. The two-axis motion module 61 can be used to realize the switching of the temperature testing part 62 between multiple test stations 11. The structure is simple and efficient.

[0077] Specifically, in some embodiments, two test stations 11 are arranged side by side in the second direction. The two-axis motion module 61 includes an X-axis motion module and a Y-axis motion module. The X-axis motion module extends along the first direction and is arranged on the work platform 100. The Y-axis motion module extends along the second direction and is arranged on the X-axis motion module. The Y-axis motion module includes the drive seat. This arrangement maximizes the travel of the drive seat, thereby reducing the space occupied by the two-axis motion modules 61 and the overall size of the optical module testing system 1000.

[0078] Since the power testing unit 63 does not need to perform large-area multi-point detection on the optical module 2000 and components such as the combiner, after the optical module 2000 is connected to the optical module testing system 1000, a laser emission port is usually reserved on the working platform 100. Since the laser generating port and the optical module 2000 are usually connected through an optical fiber, there are many possibilities for setting the laser emission port. For example, multiple laser emission ports corresponding to multiple test stations 11 are arranged adjacent to each other on the working platform 100. The power testing unit 63 only needs to switch positions between the multiple laser emission ports through sliding components such as slide rails and sliders. This is not described in detail in the embodiments of the present invention.

[0079] See also Figure 2 In some embodiments, two groups of test execution components 600 are provided, and are respectively disposed at the top and bottom of the test station 11, so as to be able to perform testing operations on the optical module from the top and bottom simultaneously.

[0080] See also Figure 14 In some embodiments, the optical module testing system 1000 also includes an optical module testing water circuit 400, which includes a circulating flow circuit 41 and two flow circuit switching structures 42. The circulating flow circuit 41 includes a water supply pipe 411 and a return water pipe 412; the flow circuit switching structure 42 has a first water port 4211a and multiple second water ports 4212a. The flow circuit switching structure 42 can selectively connect the first water port 4211a and one of the second water ports 4212a. The first water ports 4211a of the two flow circuit switching structures 42 are respectively connected to the water supply pipe 411 and the return water pipe 412; wherein the second water ports 4212a in the two flow circuit switching structures 42 correspond one to one to form a module water group, and the module water groups are respectively connected to the corresponding water channel sockets 200 to provide water supply for the cooling water channel of the corresponding optical module 2000.

[0081] It should be noted that there can be many types of flow path switching structures 42, as long as it has a first water port 4211a and multiple second water ports 4212a, and it can control and adjust the connection between the first water port 4211a and the multiple second water ports 4212a. For example, the flow path switching structure 42 can include a main pipeline and multiple branch pipelines, and the multiple branch pipelines are connected in parallel to the main pipeline. Each branch pipeline is provided with an on-off valve, and the first water port 4211a is formed in the main pipeline, and the second water port 4212a is formed in the corresponding branch pipeline. By controlling the corresponding on-off valve to open, the first water port 4211a and the corresponding second water port 4212a can be connected. This embodiment does not limit the specific structural form of the flow path switching structure 42.

[0082] Since each flow path switching structure 42 includes multiple second water ports 4212a, multiple module water ports can be formed, and each module water port group is respectively set corresponding to the test station 11, so that the optical module 2000 transported to the test station 11 can be connected thereto.

[0083] One end of the water supply pipe 411 and the return pipe 412 are respectively connected to the first water ports 4211a in the two flow path switching structures 42, and the other end is connected to the cooling water pump device, which is not described in detail in this embodiment.

[0084] According to the above technical solution, the optical module test water path 400 includes two flow path switching structures 42, and the first water port 4211a in each flow path switching structure 42 can be selectively connected to multiple second water ports 4212a. The second water ports 4212a in the two flow path switching structures 42 can be combined into multiple groups of module water groups, and the multiple groups of module water groups can be set corresponding to multiple water path sockets 200, that is, the cooling water paths of multiple optical modules 2000 can be connected to form a water loop, and the first water ports 4211a of the two flow path switching structures 42 are controlled to be connected to the second water ports 4212a corresponding to the same module water group, so that the water supply pipe 411 and the return pipe 412 can be used for The corresponding optical module 2000 cooling water path supplies cooling water, and at this time, other module water groups can be connected to other optical modules 2000 to be tested without being affected. After the test of the optical module 2000 corresponding to one group of module water groups is completed, by switching the connection between the first water port 4211a and the second water port 4212a in the two flow path switching structures 42, cooling water can be continuously supplied to the optical modules 2000 corresponding to other module water groups. The optical module 2000 is supplied with cooling water, which means that the test execution component 600 can perform test actions on it, which greatly shortens the waiting time of the test execution component 600 and improves the test efficiency of the optical module test system 1000.

[0085] Specifically, in some embodiments, the flow path switching structure 42 includes a multi-way valve 421, which has a first connector 4211 and multiple second connectors 4212; the multiple second connectors 4212 are respectively connected to the water-passing plug parts 23 on the corresponding water path sockets 200; wherein, the first water port 4211a is formed on the first connector 4211, and the second water port 4212a is formed on the second connector 4212.

[0086] It should be noted that the multi-way valve 421 has multiple ports, one of which is set as the first water port 4211a, and the other ports are set as the second water port 4212a (the number of ports of the multi-way valve 421 in this embodiment is determined according to the specific number of module water groups. For example, when the module water groups are set to three groups, the multi-way valve 421 in each flow path switching structure 42 can be specifically set as a four-way valve. When the module water groups are set to two groups, the multi-way valve 421 in each flow path switching structure 42 can be specifically set as a three-way valve). The second water port 4212a is connected to the water channel socket 200, and the water channel socket 200 can be used to connect the water channel to the water channel. The second water outlet 4212a is extended to the test station 11 for easy connection; the water channel socket 200 has various structural forms, which can be a simple pagoda head connecting pipe or a quick-plug connector, which is not limited in this embodiment; by connecting the two second water outlets 4212a in a group of module water groups to the water channel socket 200 through a pipe, a quick connection can be achieved through the water channel socket 200 and the water channel connector 5131 set on the optical module 2000, thereby improving the plug-in and unplugging efficiency of the optical module 2000 and the test water channel. This embodiment does not limit the specific plug-in form of the water channel socket 200 and the water channel connector 5131.

[0087] In some embodiments, the optical module test water circuit 400 also includes two three-way valves 43, a ventilation line 452 and an exhaust line 451. The two three-way valves 43 are respectively arranged in the water supply line 411 and the return line 412. The three-way valves 43 also have a branch connector 431; the ventilation line 452 and the exhaust line 451 are respectively connected to the branch connectors 431 of the two three-way valves 43.

[0088] Among them, the three-way valve 43 mentioned in this embodiment refers to a valve with at least three ports and three passages. By controlling the movement of the valve core, any two ports can be connected. One of the ports is formed on the branch connector 431, and the other two ports are used to be connected in series with the water supply pipe 411 or the return pipe 412 respectively; among them, the ventilation pipe 452 and the exhaust pipe 451 in this embodiment can be connected to one of the water supply pipe 411 and the return pipe 412 respectively through the three-way valve 43, and this embodiment does not limit its specific connection relationship.

[0089] It is worth mentioning that if a four-way valve or a five-way valve is set but only three ports or three passages are used, it should also be considered as the protection scope of the three-way valve 43 in this embodiment.

[0090] According to the above technical solution, three-way valves 43 are respectively provided on the water supply pipe 411 and the return water pipe 412, and the ventilation pipe 452 and the exhaust pipe 451 are connected through the branch connector 431 on the three-way valve 43. After the water flow test of the optical module 2000 is completed, the water flow of the water supply pipe 411 is blocked by controlling the channel change in the three-way valve 43, and the ventilation pipe 452 can ventilate the water supply pipe 411 or the return water pipe 412. The airflow can discharge the cooling water in the optical module 2000 to the exhaust pipe 451 through the flow path switching structure 42. Thereafter, the connection between the optical module 2000 and the module water flow group is disconnected to ensure that the cooling water in the optical module 2000 is drained.

[0091] Specifically, in some embodiments, the ventilation line 452 is connected to the water supply line 411 through the three-way valve 43, and the exhaust line 451 is connected to the return line 412 through the three-way valve 43, that is, the ventilation direction in the pipeline is consistent with the water flow direction.

[0092] Furthermore, in some embodiments, a one-way valve 47 is provided on the ventilation line 452 and / or the exhaust line 451 .

[0093] Among them, the one-way exhaust direction of the one-way valve 47 should be from the ventilation line 452 toward the exhaust line 451. The above two parallel technical features "a one-way valve 47 is provided on the ventilation line 452" and "a one-way valve 47 is provided on the exhaust line 451" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better, which can prevent impurities in the external environment from entering the circulation flow path 41, the flow path switching structure 42 and the cooling water path of the optical module 2000 through the exhaust line 451.

[0094] In some embodiments, the optical module test water circuit 400 also includes two three-way valves 43, a ventilation line 452, and a pressure measuring line 46. The two three-way valves 43 are respectively arranged in the water supply line 411 and the return line 412. The three-way valves 43 also have a branch connector 431; the ventilation line 452 and the pressure measuring line 46 are respectively connected to the branch connectors 431 of the two three-way valves 43.

[0095] The function of the pressure measuring pipe 46 is to measure the pressure of the gas flowing therein, that is, the gas pressure in the entire test water circuit. There are many specific testing methods, which are not limited in this embodiment.

[0096] According to the above technical solution, the gas pressure in the entire optical module test water circuit 400 before water is passed through the pressure measuring pipe 46 can be measured, that is, the air tightness test function can be realized, and at least the air tightness of the connection between the optical module 2000 and the two second water ports 4212a of the module water group can be ensured, providing reliable guarantee for the subsequent introduction of cooling water.

[0097] Specifically, in some embodiments, a water mist separator 461 and a pressure gauge 462 are provided on the pressure measuring pipeline 46 .

[0098] Among them, the water mist separator 461 is arranged upstream of the barometer 462. Even if there is residual moisture in the circulation flow path 41 and the flow path switching structure 42 and enters the pressure measuring line 46 along with the gas introduced through the ventilation line 452, the water mist in the gas can be separated by the water-isolating effect of the water mist separator 461, thereby preventing the barometer 462 from being damaged by moisture.

[0099] In other embodiments, the optical module test water circuit 400 also includes an exhaust line 451 and a path switching structure 44. The exhaust line 451 and the pressure measuring line 46 are connected in parallel to the corresponding branch connector 431 through the path switching structure 44. The path switching structure 44 can switch the exhaust line 451 and the pressure measuring line 46 to be connected to the branch connector 431.

[0100] It should be noted that the path switching structure 44 has the same structural form and working principle as the above-mentioned flow path switching structure 42. It can selectively connect one of the parallel exhaust pipe 451 and the pressure measuring pipe 46 to the branch connector 431 of the corresponding three-way valve 43, thereby realizing adaptive switching between the air tightness test function and the drainage function.

[0101] Specifically, referring to the figure, the passage switching structure 44 can be configured as a three-way valve.

[0102] In some embodiments, a flow meter 48 is provided on the water supply pipe 411 and / or the water return pipe 412 .

[0103] By setting the flow meter 48 , the cooling water flow rate in the circulation flow path 41 can be monitored in real time to ensure that the optical module 2000 completes the test work at the preset cooling water flow rate.

[0104] Specifically, the flow meter 48 is set on the return water pipeline 412, and the flow meter 48 can be optionally set as a temperature measuring flow meter 48.

[0105] In some embodiments, a normally closed solenoid valve 49 is provided on the water supply pipe 411 and / or the return pipe 412 .

[0106] By setting the normally closed solenoid valve 49, when cooling water is not needed, the normally closed solenoid valve 49 is automatically disconnected, which can reduce the residual cooling water in the circulation path 41 and the flow path switching structure 42 and avoid waste of cooling water.

[0107] Combined with the flow meter 48 in the above embodiment, the normally closed solenoid valve 49 can accurately control the circulation of cooling water to ensure the stability and consistency of the water supply flow.

[0108] Specifically, the multi-way valve 421 and the three-way valve 43 mentioned in the embodiment of the present invention can be partially configured as solenoid valves, which can be automatically switched on and off through electrical control.

[0109] In some embodiments, the optical module testing system 1000 further includes a liquid leakage detection belt, which is extended along the circulation flow path 41 and the water paths in the two flow path switching structures 42 .

[0110] Among them, the optical module test system 1000 includes multiple important electrical components such as the temperature test unit 62, the power test unit 63, and the test circuit. Therefore, setting up the optical module test water channel 400 therein requires ensuring that the water channel is sealed, otherwise it may cause leakage and short circuit or directly damage the electrical components. The leakage detection belt can measure the leakage situation at a position on its own extension path. Its specific structure is not described in detail in the embodiment of the present invention. Through the setting of the leakage detection belt, the sealing situation of the water channel in the optical module test water channel 400 can be monitored in real time, and the leakage point can be discovered in time, and timely feedback control can be given to control the optical module test system 1000 to shut down for inspection to avoid accidents.

[0111] See also Figure 1 、 Figure 3 and Figure 4 In one embodiment of the present invention, the optical module testing system 1000 further includes a plurality of tooling board structures 51 that can be transported to a plurality of test stations 11. The tooling board structure 51 includes a tooling board body 511, a circuit adapter structure 512, and a waterway adapter structure 513. The tooling board body 511 has an optical module placement area 5111 for placing the optical module 2000; the circuit adapter structure 512 has an electrically conductive circuit plug connector 5121 and a circuit adapter connector 5122. The circuit connector 5121 is provided on the tooling board body 511 and can be electrically plugged into the circuit socket 300. The circuit adapter 5122 is used to electrically connect to the working circuit of the optical module 2000. The water channel adapter structure 513 has a water channel connector 5131 and a water channel adapter 5132 for water conduction. The water channel connector 5131 is provided on the tooling board body 511 and can be electrically plugged into the water channel socket 200. The water channel adapter 5132 is used to conduct water to the cooling water channel of the optical module 2000.

[0112] It should be noted that the function of the tooling plate body 511 is to transport the optical module 2000 to be tested to the optical module testing system 1000. The transport method can be completed by a double-speed chain or a conveyor belt, or by a manual cart. This embodiment does not limit the transport method.

[0113] The circuit adapter 5122 is configured to connect to multiple access terminals of the working circuit of the optical module 2000 to be tested. The specific structure of the circuit adapter 5122 depends on the multiple access terminals. For example, the circuit adapter 5122 may include multiple navigation sockets, each of which is connected to one of the working circuit access terminals. Similarly, the waterway adapter 5132 is configured to connect to multiple access terminals of the cooling water circuit of the optical module 2000 to be tested. The specific structure of the circuit adapter 5122 and the waterway adapter 5132 depends on the multiple access terminals. For example, the waterway adapter 5132 may include a water diversion valve having multiple water inlets formed thereon, each of which is connected to one of the cooling water circuit access terminals. This embodiment does not limit the specific structures of the circuit adapter 5122 and the waterway adapter 5132.

[0114] The circuit connector 5121 is electrically connected to the circuit adapter 5122, for example, through the connecting line 5123 in Figure 4, the circuit connector 5121 can be directly plugged into and connected with the circuit socket 300 in the optical module testing system 1000, thereby forming an electrical circuit. This embodiment does not limit its specific structure; the water channel connector 5131 is water-connected to the water channel adapter 5132, for example, through the connecting pipe 5133 in the figure. The water channel connector 5131 can be directly plugged into and connected with the water channel socket 200 in the optical module testing system 1000, thereby forming a water circuit. This embodiment does not limit its specific structure.

[0115] According to the technical solution of the present invention, the tooling board body 511 places the optical module 2000 to be tested in the optical module placement area 5111 thereon. Before the tooling board structure 51 transfers the optical module 2000 to be tested, the circuit adapter 5122 of the circuit adapter structure 512 can be pre-connected with multiple access ends of the working circuit in the optical module 2000 to be tested. At the same time, the water channel adapter 5132 of the water channel adapter structure 513 can also be pre-connected with multiple access ends of the cooling water channel in the optical module 2000 to be tested. This process does not occupy the optical module test system 1000. After this, the tooling board structure 51 The transport can transport the optical module 2000 to be tested to the test station 11 of the optical module testing system 1000. At this time, it is only necessary to plug and connect the circuit connector 5121 of the tooling board structure 51 with the circuit socket 300 of the optical module testing system 1000, and plug and connect the water connector 5131 of the tooling board structure 51 with the water socket 200 of the optical module testing system 1000. This process only involves the connection of two connection points, which greatly shortens the time spent on manual water and electricity connection, shortens the test idle period of the optical module testing system 1000, and improves the test efficiency of the optical module testing system 1000.

[0116] In one embodiment, the water connector 5131 and the circuit connector 5121 are arranged on the same side in the length direction of the tooling board body 511. It should be noted that the projection of the tooling board body 511 in its thickness direction is generally rectangular. Generally speaking, whether it is a double-speed chain or a cart, the travel direction of the tooling board body 511 is generally its length direction. Therefore, according to the above solution, by arranging the water connector 5131 and the circuit connector 5121 on the same side in the length direction of the tooling board body 511, when the tooling board body 511 is transported to the optical module testing system 1000, by properly arranging the positions of the circuit connector 300 and the water connector 200, the circuit connector 5121 and the circuit connector 300, as well as the water connector 5131 and the water connector 200, can be directly connected and connected, further reducing the time consumed in manual water and power connection.

[0117] Both the connecting pipe 5133 connecting to the water connector 5131 and the connecting line 5123 connecting to the circuit connector 5121 occupy space on the tooling board body 511 as they extend. Furthermore, in one embodiment, the water connector 5131 and the circuit connector 5121 are spaced apart in the width direction of the tooling board body 511; along the width direction, the optical module placement area 5111 is located between the water connector 5131 and the circuit connector 5121. This arrangement allows the water connector 5131 and the circuit connector 5121 to be spaced apart in the width direction of the tooling board body 511, allowing the connecting pipe 5133 and the connecting line 5123 to be placed side by side. This leaves more usable area on the tooling board body 511, allowing for placement of components such as a combiner or wiring harness, thereby improving the space utilization of the tooling board body 511.

[0118] After the tooling board structure 51 is transferred to the test station 11 of the optical module testing system 1000, and the waterway connector 5131 and the circuit connector 5121 are respectively plugged into the waterway socket 200 and the circuit socket 300, it is necessary to ensure that the position of the optical module 2000 is fixed so that stable testing can be performed. In view of this, in one embodiment, the tooling board body 511 is also formed with a plurality of positioning holes 5112 that pass through in the thickness direction, and the plurality of positioning holes 5112 are respectively arranged on the periphery of the tooling board body 511; in another embodiment, the tooling board body 511 also has a plurality of limiting portions 5113, and the plurality of limiting portions 5113 are arranged around the periphery of the optical module placement area 5111.

[0119] It should be noted that the above two parallel technical features "the tooling plate body 511 is also formed with a plurality of positioning holes 5112 that pass through along the thickness direction, and the plurality of positioning holes 5112 are respectively arranged on the periphery of the tooling plate body 511" and "the tooling plate body 511 also has a plurality of limiting parts 5113, and the plurality of limiting parts 5113 are arranged around the peripheral side of the optical module placement area 5111" can be set selectively or at the same time. Obviously, the effect of setting them at the same time is better.

[0120] Combined with attachment Figure 2 According to the above technical solution, by setting up multiple positioning holes 5112, the optical module testing system 1000 can be inserted into the positioning holes 5112 through the positioning pins 13, thereby stably fixing the tooling board structure 51 at the test station 11, ensuring the stable progress of the testing process; by setting up multiple limiting parts 5113 on the tooling board body 511, the optical module 2000 to be tested can be stably restricted in the optical module placement area 5111, which also ensures the stable progress of the testing process.

[0121] Among existing optical modules 2000, some have open-close structures, such as the 3000S, 2000S, 4000, and 6000 types of optical modules 2000. If these optical modules 2000 are closed, multiple key internal components cannot be accurately inspected. To enable compatibility testing of these types of optical modules 2000, in one embodiment, the optical module placement area 5111 includes a first placement area 51111 and a second placement area 51112. The first placement area 51111 and the second placement area 51112 are each configured to receive two open-close structures of the unfolded optical module 2000 to be tested. It should be noted that the first placement area 51111 and the second placement area 51112 each receive two open-close structures, allowing key internal components of the optical module 2000 to be fully displayed, thereby ensuring sufficient testing of these types of optical modules 2000.

[0122] Furthermore, in one embodiment, the first placement area 51111 and the second placement area 51112 are hollowed out in the thickness direction of the tooling plate body 511 to expose the bottom of the optical module 2000 to be tested. It should be noted that although the first placement area 51111 and the second placement area 51112 are hollowed out, the edges of the optical module 2000 to be tested can still be supported on the physical structure of the tooling plate body 511. The two hollowed-out areas are only used to expose the key parts of the bottom and top of the optical module 2000 to be tested downward, while the key parts in the middle of the optical module 2000 to be tested are exposed upward after being opened. By respectively arranging the test execution components 600 on the corresponding top and ground sides of the optical module testing system 1000, the optical module 2000 to be tested can be efficiently and fully tested.

[0123] It is understandable that some types of optical modules 2000 are usually used in conjunction with a combiner, and a wire harness is connected between the two. In view of this, in one embodiment, the tooling plate body 511 further has a combiner placement platform 5114 and a wire harness placement platform 5115, and the wire harness placement platform 5115 is arranged around the combiner placement platform 5114. The combiner can be placed on the combiner placement platform 5114, and the connecting wire harness can be placed by arranging the wire harness placement platform 5115 around the combiner placement platform 5114, so that the connecting wire harness is naturally coiled around the combiner, so that both the combiner and the connecting wire harness can be fully tested.

[0124] Furthermore, in one embodiment, the combiner placement platform 5114 is disposed away from the tooling plate body 511 relative to the harness placement platform 5115 in the thickness direction of the tooling plate body 511. It should be noted that the combiner placement platform 5114 is disposed away from the tooling plate body 511 relative to the harness placement platform 5115 in the thickness direction of the tooling plate body 511, meaning that the combiner placement platform 5114 is higher than the harness placement platform 5115. This arrangement prevents the connected harness from blocking the combiner, ensuring that the combiner is fully tested.

[0125] See also Figure 3 In some embodiments, the optical module testing system 1000 includes multiple transfer carts 500, each of which includes a tooling plate structure 51 as described above and a cart body 52 that supports the tooling plate structure 51. The specific structure of the tooling plate structure 51 is similar to that of the aforementioned embodiments. Since this transfer cart 500 utilizes all the technical solutions of all the aforementioned embodiments, it at least possesses all the beneficial effects of the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here. Transporting the tooling plate structure 51 via the cart body 52 improves its mobility.

[0126] It should be noted that a plurality of transfer carts 500 are provided so that a plurality of optical modules 2000 to be tested can be transferred to the working platform 100 for testing in succession. At the same time, the complicated water and electricity connection process of the optical module 2000 can be carried out outside the working platform 100, thereby making full use of the optical module testing system 1000.

[0127] In some embodiments, the waterway connector 5131 and the circuit connector 5121 are arranged on the same side in the length direction of the tooling board body 511; the cart body 52 has a plurality of positioning structures 521 in the width direction of the tooling board structure 51; the optical module testing system 1000 is provided with a plurality of guide structures 12 corresponding to each test station 11; wherein the positioning structure 521 can be adapted to be snapped into the guide structure 12, so that the circuit connector 5121 can be guided to be inserted into the circuit socket 300, and the waterway connector 5131 can be guided to be inserted into the waterway socket 200.

[0128] It should be noted that the movement direction of the cart body 52 is usually the length direction of the tooling plate body 511. Through the movement of the corresponding test station 11 along this length direction, the circuit plug connector 5121 and the circuit socket 300, and the water plug connector 5131 and the water socket 200 can be plugged into place. Therefore, it can be determined that the setting position of the circuit socket 300 and the water socket 200 is in the length direction of the tooling plate structure 51.

[0129] It should be noted that there are many types of positioning structures 521 and guide structures 12, and the relationship between the two is that the trolley body 52 realizes the alignment of the circuit plug connector 5121 and the water plug connector 5131 on the tooling plate body 511 with the circuit socket 300 and the water socket 200 on the working platform 100 through the snap-fit ​​cooperation between the positioning structure 521 and the guide structure 12.

[0130] According to the above technical solution, after the cart body 52 is transferred to the test station 11, the positioning structure 521 provided thereon can be adapted to engage with the guide structure 12, thereby providing guidance for the movement of the cart body 52, ensuring that the circuit connector 5121 and the circuit socket 300, and the waterway connector 5131 and the waterway socket 200 are roughly aligned, so as to facilitate the subsequent connection of the waterway and circuit of the optical module 2000 and the optical module testing system 1000.

[0131] In a specific embodiment, the positioning structure 521 includes a trolley roller 5211 of the trolley body 52, and the guide structure 12 includes two guide plates. A guide groove 121 extending along a first direction is defined between the two guide plates. The trolley roller 5211 is inserted into the guide groove 121 to ensure that the circuit connector 5121 and the circuit socket 300, and the water connector 5131 and the water socket 200 are roughly aligned.

[0132] To facilitate the description of the positional relationship, the length direction, width direction and thickness direction of the tooling plate body 511 are used in the above technical scheme. It should be noted that in an embodiment of the present invention, after the tooling plate structure 51 is transferred into place, the length direction of the tooling plate body 511 is consistent with the first direction mentioned in the subsequent technical scheme, the width direction of the tooling plate body 511 is consistent with the second direction mentioned in the subsequent technical scheme, and the thickness direction of the tooling plate body 511 is consistent with the third direction mentioned in the subsequent technical scheme.

[0133] In the laser power and device temperature test process, when the tooling plate structure 51 is used to move the optical module 2000 to the test station 11 of the test system, there is generally a position deviation. Therefore, manual water supply is usually used. However, the manual water supply method has the problems of low efficiency and high labor cost. In view of this, please refer to Figures 5 to 7In some embodiments, the waterway plug connector 5131 has a water-passing plug-in portion 51311 extending in the first direction and a first matching portion 51312; the waterway plug-in socket 200 includes a first mounting structure 21, a first floating structure 22 and a water-passing plug-in portion 23, and the first mounting structure 21 is arranged on the working platform 100; the first floating structure 22 is arranged on the first mounting structure 21, and can float in a first floating plane facing the first direction, so as to have a first initial position and a first floating position, and the first floating structure 22 can reset to the first initial position autonomously, and the first floating structure 22 is formed with a first positioning portion 24 extending in the first direction, and the first positioning portion 24 can be positioned and plugged with the first matching portion 51312; the water-passing plug-in portion 23 is arranged on the first floating structure 22 facing the first direction, and the water-passing plug-in portion 23 can be plugged and connected with the water-passing plug-in portion 51311.

[0134] It should be noted that the first floating plane is a virtual plane used to define the floating motion trajectory of the first floating structure 22. For example, when the first direction is in the X direction, the first floating plane is the YZ plane. The floating arrangement of the first floating structure 22 within the first floating plane can be understood as movement in any direction within the plane. The first initial position is the position where the first floating structure 22 is automatically reset without being affected by any external force, and the first floating position is any position within the first floating plane that the first floating structure 22 can be in, except for the first initial position. Therefore, there are many first floating positions. Through the positioning and guiding effects of the first matching portion 51312 and the first positioning portion 24, the first floating structure 22 can move to the first floating position corresponding to the waterway plug joint 5131.

[0135] It should be noted that one end of the water-passing plug-in part 23 is connected to the optical module test water path 400 of the optical module testing system 1000, and the other end is used to communicate with the water-passing plug-in part 51311. This embodiment does not limit the specific structural form of the water-passing plug-in part 23. For example, in one embodiment, the water-passing plug-in part 23 includes a pneumatic quick-connect connector, which is automatically contracted by the control of the solenoid valve, thereby ensuring the tightness of the connection with the water-passing plug-in part 51311.

[0136] According to the technical solution of the present invention, the waterway socket 200 is arranged on the working platform 100 of the optical module test system 1000. When the tooling plate structure 51 loaded with the optical module 2000 is moved to the test station 11 of the working platform 100, even if there is a certain position deviation, the first matching portion 51312 of the waterway plug connector 5131 on the tooling plate structure 51 can pre-contact the first positioning portion 24 of the waterway socket 200 in the first direction, thereby driving the first floating structure 22 to move to the waterway plug connector 5131 through the positioning and guiding effect of the first positioning portion 24 and the first matching portion 51312. 1, and then the water-passing plug-in part 23 on the first floating structure 22 is opposite to the water-passing plug-in part 51311 on the water-passing plug-in joint 5131 in the first direction. In the subsequent opposite-direction plug-in activity of the water-passing plug-in part 23 and the water-passing plug-in part 51311, the water-passing plug-in part 23 can be opposite to the water-passing plug-in part 51311 for water-passing, which changes the current situation in which the water connection process of the optical module 2000 is completely completed manually in the existing laser power and temperature test process of each component of the optical module 2000, improves the water connection efficiency of the optical module 2000, and reduces the manpower cost.

[0137] There are many ways to realize the floating movement of the first floating structure 22 in the first floating plane. For example, the floating and resetting of the first floating structure 22 can be realized by pulling the first floating structure 22 in different radial directions in the first floating plane on the circumferential side of the first floating structure 22 with multiple tension springs. However, this type of structure is relatively complex, and the repeatability of the first initial position of the first floating structure 22 is difficult to ensure. In view of this, please refer to Figure 7 In one embodiment, the first mounting structure 21 includes a first transverse movable portion 2121 that moves along the second direction, and the first transverse movable portion 2121 is provided with a first longitudinal movable portion 2122 that can move along the third direction; the first floating structure 22 is provided on the first longitudinal movable portion 2122; wherein the second direction and the third direction are two directions perpendicular to each other in the first floating plane.

[0138] It should be noted that since the second direction and the third direction are two directions perpendicular to each other in the first floating plane, and the first horizontal movable part 2121 and the first longitudinal movable part 2122 can move relative to each other, according to the above technical solution, under the coordinated movement of the first horizontal movable part 2121 and the first longitudinal movable part 2122, the first floating structure 22 can be adjusted to any first floating position in the first floating plane. At the same time, the structural form of the first mounting structure 21 is relatively simple. It only needs to control the reset of the first horizontal movable part 2121 and the first longitudinal movable part 2122 to drive the first floating structure 22 to reset to the first initial position, thereby ensuring the repeated position accuracy of the first initial position, which is conducive to the accurate plugging of the waterway plug connector 5131 and the waterway plug socket 200.

[0139] Specifically, see Figure 7 Regarding the reset implementation form of the first floating structure 22, in one embodiment, a first elastic member 2123 is provided between the first transverse movable portion 2121 and the first longitudinal movable portion 2122; a second elastic member 2124 is provided between the first transverse movable portion 2121 and the first mounting structure 21; under the pushing action of the first elastic member 2123 and the second elastic member 2124, the first floating structure 22 can autonomously reset to the first initial position.

[0140] It should be noted that the first elastic member 2123 and the second elastic member 2124 may be in the form of elastic rubber or a spring, and this embodiment does not limit their specific structural forms.

[0141] According to the above technical solution, by setting the first elastic member 2123, a thrust can be provided for the reset of the first transverse movable part 2121, and by setting the second elastic member 2124, a thrust can be provided for the reset of the first longitudinal movable part 2122. Under the cooperation of the first elastic member 2123 and the second elastic member 2124, it can be ensured that the first floating structure 22 is accurately and quickly reset to the first initial position.

[0142] The process of mutual plugging of the water-passing plug-in portion 23 of the water-passing plug-in seat 200 and the water-passing plug-in portion 51311 of the water-passing plug-in connector 5131 can be achieved by manually pushing the transfer cart 500. However, the force of manual pushing is not easy to control, which may cause the water-passing plug-in portion 23 and the water-passing plug-in portion 51311 to collide and be damaged. In view of this, please refer to Figure 6 In one embodiment, the first mounting structure 21 includes a first mounting seat 211 and a first movable seat 212 . The first movable seat 212 is movably disposed on the first mounting seat 211 along a first direction. The first transverse movable portion 2121 is disposed on the first movable seat 212 .

[0143] It should be noted that the movement of the first movable seat 212 relative to the first mounting seat 211 can be completed by manpower or by other means. This embodiment only limits the first movable seat 212 to be able to move along the first direction, and does not limit its movement form.

[0144] According to the above technical solution, the water-passing connecting part 23 of the water-passing connecting seat 200 and the water-passing connecting part 51311 of the water-passing connecting joint 5131 can be conveniently connected to each other through the movable adjustment of the first movable seat 212. Since the process is relatively controllable, it is not likely to cause the water-passing connecting part 23 to collide with the water-passing connecting part 51311. Moreover, after the test is completed, the water-passing connecting part 23 can be driven to separate from the water-passing connecting part 51311 through the first movable seat 212, so that the tooling board structure 51 can be easily pulled away from the test station 11 of the optical module test system 1000.

[0145] Further, see Figure 6 In one embodiment, a first driving device 25 is provided on the first mounting seat 211, and the first driving device 25 has a first driving portion that moves along the first direction, and the first driving portion is provided on the first movable seat 212; and / or, a first linear guide component 26 is provided between the first mounting seat 211 and the first movable seat 212, and the first linear guide component 26 is used to provide guidance for the first movable seat 212 in the first direction.

[0146] It should be noted that the specific structure of the first driving device 25 can be a push rod motor or a driving cylinder, which is not limited in this embodiment. The specific structure of the first linear guide assembly 26 can be a linear guide rail slider structure or a guide rod sleeve structure, which is also not limited in this embodiment.

[0147] It should be noted that the above two parallel technical features "a first driving device 25 is provided on the first mounting seat 211, the first driving device 25 has a first driving part that moves along the first direction, and the first driving part is provided on the first movable seat 212" and "a first linear guide assembly 26 is provided between the first mounting seat 211 and the first movable seat 212, and the first linear guide assembly 26 is used to provide guidance for the first movable seat 212 in the first direction" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better.

[0148] According to the above technical solution, a first driving device 25 is provided to drive the first movable seat 212 to move through the first driving part, which can automatically complete the mutual plug-in of the water-passing plug-in part 23 of the water-passing plug-in seat 200 and the water-passing plug-in part 51311 of the water-passing plug-in joint 5131, further reducing the labor intensity and improving the plug-in and pull-out efficiency of the water-passing plug-in part 23 and the water-passing plug-in part 51311. The provision of the first linear guide assembly 26 can provide a connection basis for the first movable seat 212 and the first mounting seat 211, and can also provide guidance along the first direction to ensure the accurate plug-in and connection of the water-passing plug-in part 23 and the water-passing plug-in part 51311.

[0149] Specifically, see Figure 7In one embodiment, the first transverse movable portion 2121 has two first transverse mounting side walls that are opposite to each other in the second direction, and the first longitudinal movable portion 2122 is respectively mounted to the two first transverse mounting side walls at both ends in the second direction; and / or

[0150] The first mounting structure 21 has two first longitudinal mounting side walls that are opposite to each other in the third direction. The first transverse movable portion 2121 is respectively mounted to the two first longitudinal mounting side walls at both ends in the third direction.

[0151] It should be noted that the first longitudinal movable portion 2122 is connected to the corresponding first transverse mounting side wall by sliding along the third direction at its end in the second direction, and the first transverse movable portion 2121 is connected to the corresponding first longitudinal mounting side wall by sliding along the second direction at its end in the third direction.

[0152] It should be noted that the above two parallel technical features "the first horizontal movable part 2121 has two first horizontal mounting side walls opposite to each other in the second direction, and the first longitudinal movable part 2122 is respectively installed to the two first horizontal mounting side walls at both ends of the second direction" and "the first mounting structure 21 has two first longitudinal mounting side walls opposite to each other in the third direction, and the first horizontal movable part 2121 is respectively installed to the two first longitudinal mounting side walls at both ends of the third direction" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better.

[0153] According to the above technical solution, by setting up two first transverse mounting side walls, an installation base can be provided for both ends of the first longitudinal movable part 2122, so that the center of gravity of the first longitudinal movable part 2122 is between the two first transverse mounting side walls, which is beneficial to ensuring the smoothness of the first longitudinal movable part 2122 when it moves on the first transverse movable part 2121. Similarly, by setting up two first longitudinal mounting side walls, an installation base can be provided for both ends of the first transverse movable part 2121, so that the center of gravity of the first transverse movable part 2121 is between the two first longitudinal mounting side walls, which is beneficial to ensuring the smoothness of the first transverse movable part 2121 when it moves on the first mounting structure 21.

[0154] Specifically, see Figure 7 In one embodiment, a first guide assembly 27 is provided between the end of the first longitudinal movable portion 2122 in the second direction and the corresponding first transverse mounting side wall, and a second guide assembly 28 is provided between the end of the first transverse movable portion 2121 in the third direction and the corresponding first longitudinal mounting side wall.

[0155] Specifically, see Figure 7In one embodiment, the first movable seat 212 includes a first mounting frame, the first horizontal movable portion 2121 includes a second mounting frame, the first longitudinal movable portion 2122 includes a third mounting frame, the second mounting frame moves in a second direction within the first mounting frame, and the third mounting frame moves in a third direction within the second mounting frame. The first mounting frame includes two first longitudinal mounting side walls, the second frame includes two first horizontal mounting side walls, and the first floating structure 22 is arranged on the third frame.

[0156] Considering that the positioning of a single first positioning portion 24 may cause the water-passing plug-in portion 23 to deflect relative to the first positioning portion 24, which may cause the plug-in failure of the water-passing plug-in portion 23 and the water-passing plug-in portion 51311, please refer to Figure 5 and Figure 7 In one embodiment, multiple first positioning portions 24 are provided along the extension direction of the first floating plane. According to the above technical solution, the provision of multiple first positioning portions 24 further limits the rotational freedom of the first floating structure 22, thereby preventing the water-passing plug-in portion 23 from deflecting relative to the first positioning portions 24 and ensuring accurate insertion and connection between the water-passing plug-in portion 23 and the water-passing mating portion 51311.

[0157] Generally speaking, the optical module test water path of the optical module test system needs to form a loop with the cooling water path of the optical module. Therefore, at least two sets of water path adapter components are required between the tooling plate structure 51 and the working platform 100 of the optical module test system 1000. The two sets of water path adapter components can be set separately, but setting them separately will cause the water connection pipes to occupy too much system space. In view of this, please refer to Figure 5 and Figure 7 In one embodiment, two water-passing plugs 23 are provided along the extension direction of the first floating plane, and the two water-passing plugs 23 are used for water inlet and outlet, respectively. According to the above technical solution, by providing two water-passing plugs 23, one for inlet and one for outlet, a cooling water circulation circuit can be formed. Furthermore, the two water-passing plugs 23 are arranged on the same first floating structure 22, ensuring that their respective water-passing pipes extend in parallel, thus reducing the space occupied by the water-passing pipes in the system.

[0158] Furthermore, in one embodiment, a plurality of first positioning portions 24 are provided in the extension direction of the first floating plane, and correspondingly, a plurality of first matching portions 51312 are provided; and / or,

[0159] Two water-passing plug-in parts 23 are provided in the extension direction of the first floating plane, and correspondingly, two water-passing plug-in parts 51311 are provided.

[0160] It should be noted that the above two parallel technical features "a plurality of first positioning portions 24 are provided in the extension direction of the first floating plane, and correspondingly, a plurality of first matching portions 51312 are provided" and "two water-passing plug-in portions 23 are provided in the extension direction of the first floating plane, and correspondingly, two water-passing plug-in portions 51311 are provided" can be provided selectively or simultaneously. Obviously, the effect of providing the same settings is better.

[0161] According to the above technical solution, by setting up multiple first positioning parts 24 and multiple first matching parts 51312, the rotational freedom of the first floating structure 22 can be further limited, thereby avoiding the water-passing plug-in part 23 from deflecting relative to the first positioning part 24, ensuring the accurate plug-in and conduction of the water-passing plug-in part 23 and the water-passing plug-in part 51311; by setting up two water-passing plug-ins 23, one in and one out, a cooling circulation water path can be formed. At the same time, the two water-passing plug-ins 23 are set on the same first floating structure 22, which can ensure that their respective water-passing pipes extend in parallel, that is, reducing the occupation of the system space by the water-passing pipes. The two water-passing plug-ins 23 are set on the same water-passing plug-in connector 5131, which is also conducive to the integrated arrangement of the water-passing pipes between the water-passing plug-in connector 5131 and the optical module 2000 to be tested.

[0162] In some embodiments, the circuit plug connector 5121 has multiple adapter parts 51211 arranged in a first direction; the circuit socket 300 includes a power supply structure 33 and a protective structure 34, the power supply structure 33 is formed with multiple power supply parts 331, the power supply parts 331 are extended in the first direction and can be in contact and conductive with the multiple adapter parts 51211; the protective structure 34 is movably arranged on the power supply structure 33 along the first direction, and multiple through holes 341 are formed on the protective structure 34, the multiple through holes 341 are arranged in alignment with the multiple power supply parts 331, the protective structure 34 has a protective position and an exposed position within its movable range, and the protective structure 34 can be reset to the protective position autonomously; when the protective structure 34 is in the protective position, the multiple power supply parts 331 are relatively retracted into the through holes 341; when the protective structure 34 is in the exposed position, the multiple power supply parts 331 are relatively protruded from the through holes 341.

[0163] It should be noted that the protective structure 34 can move along the first direction, and it should also have a limiting resistance to movement in other directions, so that it can play a protective role for the multiple power supply parts 331. The protective structure 34 has various structural forms, and its specific form is related to the length of the power supply part 331. For example, when the length of the power supply part 331 is short, the thickness of the protective structure 34 should be set to be thinner, so that it can ensure that when it moves to the exposed position, the power supply part 331 can protrude from its via 341. This embodiment does not limit its specific structure.

[0164] It should be noted that the specific structural form of the multiple power supply parts 331 can also be set in the form of probes or syringes, which is not limited in this embodiment.

[0165] According to the technical solution of the present invention, the circuit socket 300 is arranged on the working platform 100 of the optical module test system 1000. When the tooling plate structure 51 loaded with the optical module 2000 is moved to the test station 11 of the working platform 100, the circuit socket 300 is squeezed along the first direction by the circuit plug connector 5121 on the tooling plate structure 51. The protective structure 34 of the circuit socket 300 can be squeezed to the exposed position, so that the multiple power supply parts 331 of the power supply structure 33 protrude from the through holes 341 of the protective structure 34, thereby The multiple adapter parts 51211 of the circuit plug connector 5121 are in contact and conductive. After the test of the optical module 2000 is completed and the tooling board structure 51 leaves the test station 11, the protective structure 34 of the circuit socket 300 can automatically reset to the protective position due to the loss of the squeezing effect of the circuit plug connector 5121. The multiple power supply parts 331 are relatively retracted into the through holes 341 of the protective structure 34, so that they are timely shielded and protected by the protective structure 34, thereby avoiding the multiple power supply parts 331 from mechanical impact from the external environment.

[0166] See also Figure 11 and Figure 12 In one embodiment, a proximity switch 332 is further provided on the power supply structure 33, and the proximity switch 332 is used to trigger a proximity signal when contacting the circuit plug connector 5121; and / or,

[0167] A guide and reset structure 333 is further provided between the power supply structure 33 and the protection structure 34 . A plurality of guide and reset structures 333 are provided and arranged along the circumference of the protection structure 34 .

[0168] It should be noted that the two parallel technical features above, "a proximity switch 332 is further provided on the power supply structure 33, and the proximity switch 332 is used to trigger a proximity signal when contacting the circuit plug connector 5121" and "a guide reset structure 333 is further provided between the power supply structure 33 and the protective structure 34, and a plurality of guide reset structures 333 are provided and arranged along the circumference of the protective structure 34" can be provided separately or simultaneously. Obviously, providing both simultaneously will achieve better results.

[0169] It should be noted that the functions of the guide reset structure 333 include providing a guiding function for the protective structure 34 along the second direction, and providing a reset force for the protective structure 34 toward the protective position. The guide reset structure 333 has various forms, for example, it may include a reset spring and a guide assembly, the guide assembly includes a guide rod and a guide sleeve sleeve mounted on the guide rod, one end of the guide rod is set on the power supply structure 33, the guide sleeve is set on the protective structure 34, and the reset spring is sleeved on the guide rod and is located between the power supply structure 33 and the guide sleeve. In this way, the guiding and resetting requirements of the guide reset structure 333 can be met. Of course, the guide reset structure 333 can also be other structural forms, which is not limited in this embodiment.

[0170] According to the above technical solution, the proximity switch 332 can be used to trigger a proximity signal when the circuit contact head approaches the power supply structure 33, which means that the power supply part 331 and the adapter part 51211 are in contact. When the power supply control device receives the proximity signal, it can control the power supply of the test circuit or control the relevant indicator light to light up; by arranging multiple guide and reset structures 333 on the peripheral side of the protective structure 34, it can provide guiding and reset effects for various positions of the protective structure 34, thereby ensuring the smooth movement of the protective structure 34 and its anti-impact ability.

[0171] In the laser power and device temperature test process, when the optical module 2000 is moved to the test station 11 of the test system using the tooling plate structure 51, there is generally a position deviation. Therefore, manual power connection is usually adopted. However, the manual power connection method has the problems of low efficiency and high labor cost. In view of this, please refer to Figures 8 to 10 and Figure 13 In one embodiment, the circuit plug connector 5121 also has a second mating portion 51212 extending toward the first direction; the circuit socket 300 also includes a second mounting structure 31, and the second mounting structure 31 is arranged on the working platform 100. A second floating structure 32 is arranged on the second mounting structure 31. The second floating structure 32 can float in a second floating plane toward the first direction to have a second initial position and a second floating position. The second floating structure 32 can reset to the second initial position autonomously. The second floating structure 32 is formed with a second positioning portion 321 extending toward the first direction, and the second positioning portion 321 can be positioned and plugged with the second mating portion 51212; the power supply structure 33 is arranged on the second floating structure 32.

[0172] It should be noted that the circuit plug connector 5121 mentioned in this embodiment is provided with a second matching portion 51212 which is aligned with the second positioning portion 321 in the circuit socket 300 to realize the function of plug-in positioning; wherein, the second floating plane is a virtual plane, which is used to limit the floating motion trajectory of the second floating structure 32. For example, when the first direction is in the X direction, the second floating plane belongs to the YZ plane. The floating setting of the second floating structure 32 in the second floating plane can be understood as moving in any direction in the plane. The second initial position is the position where the second floating structure 32 is automatically reset without being affected by any external force, and the second floating position is any position in the second floating plane that the second floating structure 32 can be in except the second initial position. Therefore, there are many second floating positions. Through the positioning and guiding effect of the second matching portion 51212 and the positioning, the second floating structure 32 can move to the second floating position corresponding to the circuit plug connector 5121.

[0173] According to the technical solution of the present invention, the second mounting structure 31 of the circuit socket 300 is arranged on the working platform 100 of the optical module test system 1000. When the tooling plate structure 51 loaded with the optical module 2000 is moved to the test station 11 of the working platform 100, even if there is a certain position deviation, the second matching portion 51212 of the circuit plug connector 5121 on the tooling plate structure 51 can be pre-contacted with the second positioning portion 321 of the circuit socket 300 in the first direction, thereby driving the second floating joint 31 to move forward through the positioning and guiding effect of the second positioning portion 321 and the second matching portion 51212. The structure 32 moves to a second floating position corresponding to the position of the circuit plug connector 5121. Thereafter, the multiple power supply parts 331 on the power supply structure 33 and the multiple adapter parts 51211 on the circuit plug connector 5121 are directly opposite to each other in the first direction. In the subsequent process of the power supply part 331 and the adapter part 51211 moving toward each other, the power supply part 331 can be directly in contact with the adapter part 51211 and be connected. This changes the current situation in which the power connection process of the optical module 2000 in the existing optical module 2000 testing process is completely completed manually, thereby improving the power connection efficiency of the optical module 2000 and reducing the manpower cost.

[0174] There are many ways to implement the floating movement of the second floating structure 32 within the second floating plane. For example, by using multiple tension springs to pull the second floating structure 32 along different radial directions within the second floating plane on the circumferential side of the second floating structure 32, the floating and resetting of the second floating structure 32 can be achieved. However, this type of structure is relatively complex, and the repeatability of the second initial position of the second floating structure 32 is difficult to guarantee. In view of this, in one embodiment, the second mounting structure 31 includes a second lateral movable portion 3121 that moves along the second direction, and a second longitudinal movable portion 3122 that can move along a third direction is provided on the second lateral movable portion 3121; the second floating structure 32 is provided on the second longitudinal movable portion 3122; wherein the second direction and the third direction are two directions perpendicular to each other within the second floating plane.

[0175] It should be noted that, since the second direction and the third direction are two directions perpendicular to each other in the second floating plane, and the second horizontal movable part 3121 and the second longitudinal movable part 3122 can move relative to each other, according to the above technical solution, under the coordinated action of the second horizontal movable part 3121 and the second longitudinal movable part 3122, the second floating structure 32 can be adjusted to any second floating position in the second floating plane. At the same time, the structural form of the second mounting structure 31 is relatively simple. It only needs to control the reset of the second horizontal movable part 3121 and the second longitudinal movable part 3122 to drive the second floating structure 32 to reset to the second initial position, thereby ensuring the repeatable position accuracy of the second initial position, which is conducive to the accurate plugging of the circuit plug connector 5121 and the circuit socket 300.

[0176] Specifically, see Figure 10 In one embodiment, the second transverse movable portion 3121 has two second transverse mounting side walls 3121 a opposite to each other in the second direction, and the second longitudinal movable portion 3122 is respectively mounted to the two second transverse mounting side walls 3121 a at both ends in the second direction; and / or

[0177] The second mounting structure 31 has two second longitudinal mounting side walls 312 a opposite to each other in the third direction. The second transverse movable portion 3121 is respectively mounted to the two second longitudinal mounting side walls 312 a at both ends in the third direction.

[0178] It should be noted that the second longitudinal movable portion 3122 is connected to the corresponding second transverse mounting side wall 3121a by sliding along the third direction at its end in the second direction, and the second transverse movable portion 3121 is connected to the corresponding second longitudinal mounting side wall 312a by sliding along the second direction at its end in the third direction.

[0179] It should be noted that the above two parallel technical features "the second horizontal movable part 3121 has two second horizontal mounting side walls 3121a opposite to each other in the second direction, and the second longitudinal movable part 3122 is respectively installed to the two second horizontal mounting side walls 3121a at both ends of the second direction" and "the second mounting structure 31 has two second longitudinal mounting side walls 312a opposite to each other in the third direction, and the second horizontal movable part 3121 is respectively installed to the two second longitudinal mounting side walls 312a at both ends of the third direction" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better.

[0180] According to the above technical solution, by providing the two second transverse mounting side walls 3121a, a mounting base can be provided for both ends of the second longitudinal movable part 3122, so that the center of gravity of the second longitudinal movable part 3122 is located between the two second transverse mounting side walls 3121a, which is beneficial to ensuring the smoothness of the second longitudinal movable part 3122 when moving on the second transverse movable part 3121. Similarly, by providing the two second longitudinal mounting side walls 312a, a mounting base can be provided for both ends of the second transverse movable part 3121, so that the center of gravity of the second transverse movable part 3121 is located between the two second longitudinal mounting side walls 312a, which is beneficial to ensuring the smoothness of the second transverse movable part 3121 when moving on the second mounting structure 31.

[0181] Specifically, see Figure 10 In one embodiment, a third guide assembly 37 is provided between the end of the second longitudinal movable portion 3122 in the second direction and the corresponding second transverse mounting side wall 3121a, and a fourth guide assembly 38 is provided between the end of the second transverse movable portion 3121 in the third direction and the corresponding second longitudinal mounting side wall 312a.

[0182] Specifically, regarding the reset implementation form of the second floating structure 32, in one embodiment, a third elastic member 3123 is provided between the second transverse movable portion 3121 and the second longitudinal movable portion 3122; a fourth elastic member 3124 is provided between the second transverse movable portion 3121 and the second mounting structure 31; under the pushing action of the third elastic member 3123 and the fourth elastic member 3124, the second floating structure 32 can autonomously reset to the second initial position.

[0183] It should be noted that the third elastic member 3123 and the fourth elastic member 3124 may be in the form of elastic rubber or a spring, and this embodiment does not limit their specific structural forms.

[0184] According to the above technical solution, by setting the third elastic member 3123, a thrust can be provided for the reset of the second transverse movable part 3121, and by setting the fourth elastic member 3124, a thrust can be provided for the reset of the second longitudinal movable part 3122. Under the cooperation of the third elastic member 3123 and the fourth elastic member 3124, it can be ensured that the second floating structure 32 is accurately and quickly reset to the second initial position.

[0185] The process of plugging the multiple power supply parts 331 of the circuit socket 300 and the multiple adapter parts 51211 of the circuit plug connector 5121 together can be achieved by manually pushing the tooling plate structure 51. However, the force of the manual push is not easy to control, which may cause the multiple power supply parts 331 and the multiple adapter parts 51211 to collide and be damaged. In view of this, please refer to Figure 1 and Figure 2 In one embodiment, the second mounting structure 31 includes a second mounting seat 311 and a second movable seat 312 . The second movable seat 312 is movably disposed on the second mounting seat 311 along the first direction. The second transverse movable portion 3121 is disposed on the second movable seat 312 .

[0186] It should be noted that the movement of the second movable seat 312 relative to the second mounting seat 311 can be completed by manpower or by other means. This embodiment only limits the second movable seat 312 to be able to move along the first direction, and does not limit its movement form.

[0187] According to the above technical solution, through the movable adjustment of the second movable seat 312, the multiple power supply parts 331 of the circuit socket 300 and the multiple adapter parts 51211 of the circuit plug connector 5121 can be easily connected to each other. Since the process is relatively controllable, it is not likely to cause the multiple power supply parts 331 to collide with the multiple adapter parts 51211. Not only that, after the test is completed, the multiple power supply parts 331 can be driven to separate from the multiple adapter parts 51211 through the second movable seat 312, so that the tooling board structure 51 can be easily pulled away from the optical module testing system 1000.

[0188] Furthermore, in one embodiment, a second driving device 35 is provided on the second mounting seat 311, the second driving device 35 has a second driving portion that moves along the first direction, and the second driving portion is provided on the second movable seat 312; and / or, a second linear guide assembly 36 is provided between the second mounting seat 311 and the second movable seat 312, and the second linear guide assembly 36 is used to provide guidance for the second movable seat 312 in the first direction.

[0189] It should be noted that the specific structure of the second driving device 35 can be a push rod motor or a driving cylinder, which is not limited in this embodiment. The specific structure of the second linear guide assembly 36 can be a linear guide rail slider structure or a guide rod sleeve structure, which is also not limited in this embodiment.

[0190] It should be noted that the above two parallel technical features "a second driving device 35 is provided on the second mounting seat 311, the second driving device 35 has a second driving part that moves along the first direction, and the second driving part is provided on the second movable seat 312" and "a second linear guide assembly 36 is provided between the second mounting seat 311 and the second movable seat 312, and the second linear guide assembly 36 is used to provide guidance for the second movable seat 312 in the first direction" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better.

[0191] According to the above technical solution, a second driving device 35 is provided to drive the second movable seat 312 through the second driving part, which can automatically complete the mutual plug-in of the water-passing plug-in part 23 of the water-passing plug-in seat 200 and the water-passing plug-in part 51311 of the water-passing plug-in joint 5131, further reducing the labor intensity and improving the plug-in and pull-out efficiency of the water-passing plug-in part 23 and the water-passing plug-in part 51311. The second linear guide assembly 36 is provided to provide a connection basis for the second movable seat 312 and the second mounting seat 311, and can also provide guidance along the first direction to ensure the accurate plug-in and connection of the water-passing plug-in part 23 and the water-passing plug-in part 51311.

[0192] For details, please refer to Figure 10 In one embodiment, the second movable seat 312 includes a first mounting frame, the second horizontal movable portion 3121 includes a second mounting frame, the second longitudinal movable portion 3122 includes a third mounting frame, the second mounting frame moves in a second direction within the first mounting frame, and the third mounting frame moves in a third direction within the second mounting frame. The first mounting frame includes two second longitudinal mounting side walls 312a, the second frame includes two second horizontal mounting side walls 3121a, and the second floating structure 32 is arranged on the third frame.

[0193] Generally speaking, the test circuit needs to form a power supply loop. Therefore, at least two sets of circuit adapter components are required between the tooling board structure 51 and the optical module test system 1000. The two sets of circuit adapter components can be set separately, but setting them separately will cause the power connection lines to occupy too much system space. In view of this, in one embodiment, the power supply structure 33 and the protection structure 34 are combined into a power supply protection group in a one-to-one correspondence. Two sets of power supply protection groups are set in the extension direction of the second floating plane. The two power supply protection groups are used to form a power supply loop with the two adapter groups on the circuit plug connector 5121. According to the above technical solution, a power supply loop can be formed by setting two power supply protection groups. At the same time, the two power supply protection groups are set on the same second floating structure 32, which can ensure that their respective power connection lines extend in parallel, that is, reduce the space occupied by the power connection lines.

[0194] The position accuracy of the tooling plate structure 51 usually has deviations. The second floating structure 32 needs to be positioned to the corresponding second floating position through the contact between the second positioning portion 321 and the second matching portion 51212. Only then can the power supply portion 331 and the adapter portion 51211 be contacted and connected. To ensure the order of positioning and connection, please refer to Figure 11 or Figure 12 In one embodiment, in the first direction, the end of the second positioning portion 321 is disposed farther from the second floating structure 32 than the power supply portion 331. Thus, the second positioning portion 321 can contact the circuit connector 5121 before the power supply portion 331, thereby pre-positioning the second floating structure 32.

Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
