[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the 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 contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0034] During the production process of optical modules, it is usually necessary to go through the laser power and device temperature testing process. In this process, the optical module needs to be operated into the test system and the test water circuit needs to be connected to the optical module. However, the existing test water circuit only has one set of module water plugs, which requires the test execution component of the test system to spend a long time waiting for the optical module and the test water circuit to be plugged in and out, resulting in low test efficiency of the test system.

[0035] From the analysis of the above reasons, it can be seen that since the test water circuit only has a single set of module water plugs, the tested optical module needs to be completely disconnected from the module water plug before the next optical module to be tested can be connected to the test water circuit through the module water plug. However, whether it is disconnecting or connecting the test water circuit, it takes a certain amount of time. It can be considered to set up multiple sets of module water plugs, so that when one set of module water plugs is disconnected from the tested optical module, the module water plugs of other sets can be used for the optical module to be tested to connect to the test water circuit, thereby shortening the time spent on plugging and unplugging the optical module and improving the testing efficiency of the testing system.

[0036] In view of this, the utility model proposes an optical module test waterway and an optical module test system, aiming to alleviate the problem that the test execution component in the existing optical module test system has a long waiting time, resulting in low test efficiency of the test system. Figure 1 A schematic diagram of water circuit connection of an optical module test water circuit according to an embodiment of the present invention.

[0037] See also Figure 1 In one embodiment of the utility model, the optical module test water circuit 100 is used in an optical module test system, and the optical module test system has multiple test stations, characterized in that the optical module test water circuit 100 includes a circulating flow path 1 and two flow path switching structures 2, the circulating flow path 1 includes a water supply pipeline 11 and a return water pipeline 12; the flow path switching structure 2 has a first water port 211a and multiple second water ports 22a, the flow path switching structure 2 can selectively connect the first water port 211a and one of the second water ports 22a, and the first water ports 211a of the two flow path switching structures 2 are respectively connected to the water supply pipeline 11 and the return water pipeline 12; wherein the second water ports 22a in the two flow path switching structures 2 correspond one to one to form a module water group, and multiple groups of module water groups are respectively used to correspond to multiple test station settings.

[0038] It should be noted that there can be many types of the flow path switching structure 2, as long as it has a first water opening 211a and multiple second water openings 22a, and it can control and adjust the connection between the first water opening 211a and the multiple second water openings 22a. For example, the flow path switching structure 2 may 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 opening 211a is formed in the main pipeline, and the second water opening 22a is formed in the corresponding branch pipeline. By controlling the corresponding on-off valve to open, the first water opening 211a and the corresponding second water opening 22a can be connected. This embodiment does not limit the specific structural form of the flow path switching structure 2.

[0039] Since each flow path switching structure 2 includes a plurality of second water ports 22a, a plurality of module water ports can be formed, each of which corresponds to a test station, so that the optical module 200 transported to the test station can communicate with it.

[0040] One end of the water supply pipe and the water return pipe are respectively connected to the first water ports 211a in the two flow path switching structures 2, and the other end is connected to the intermediate cooling water pump device, which is not described in detail in this embodiment.

[0041] In the technical solution of the utility model, the optical module test water circuit 100 includes two flow path switching structures 2, and the first water port 211a in each flow path switching structure 2 can be selectively connected to multiple second water ports 22a. The second water ports 22a in the two flow path switching structures 2 can be combined into multiple groups of module water groups, and the multiple groups of module water groups can correspond to multiple test station settings, that is, the cooling water paths of multiple optical modules 200 can be connected to form a water circuit. The first water ports 211a of the two flow path switching structures 2 are controlled to be connected to the second water ports 22a corresponding to the same module water group, and the water supply pipe 11 and the return pipe 11 can be connected to each other. 12 supplies cooling water to the cooling water path of the corresponding optical module 200, and at this time, other module water groups can be connected to other optical modules 200 to be tested without being affected. After the test of the optical module 200 corresponding to one group of module water groups is completed, by switching the connection between the first water port 211a and the second water port 22a in the two flow path switching structures 2, cooling water can be continuously supplied to the optical modules 200 corresponding to the other module water groups. The cooling water supply to the optical module 200 means that the test execution component can perform test actions on it, which greatly shortens the waiting time of the test execution component and improves the test efficiency of the test system.

[0042] Specifically, in some embodiments, the flow path switching structure 2 includes a multi-way valve 21 and a plurality of water-passing plug-ins 22, the multi-way valve 21 having a first connector 211 and a plurality of second connectors 212; the plurality of water-passing plug-ins 22 are respectively connected to the corresponding plurality of second connectors 212; wherein the first water port 211a is formed on the first connector 211, and the second water port 22a is formed on the water-passing plug-in 22; the two water-passing plug-ins 22 corresponding to the module water-passing group are used to be installed on the water path socket to correspond to the test station setting.

[0043] It should be noted that the multi-way valve 21 has multiple ports, one of which is set as the first water port 211a, and the other ports are connected to the water plug-in portion 22 through a hose or other water pipeline (the number of ports of the multi-way valve 21 in this embodiment depends on the specific number of module water groups. For example, when the module water groups are set to three groups, the multi-way valve 21 in each flow path switching structure 2 can be specifically set to a four-way valve; when the module water groups are set to two groups, the multi-way valve 21 in each flow path switching structure 2 can be specifically set to a three-way valve). The second water port 22a is formed in the water plug-in portion 22, and the first water port 22a can be connected to the water plug-in portion 22 through the water plug-in portion 22. The two water through ports 22a extend to the test station for easy connection. The water through connector 22 has various structural forms, which may be a simple pagoda head connecting tube or a quick-plug connector, which is not limited in the present embodiment. By arranging two water through connectors 22 corresponding to the two second water through ports 22a in a group of module water through ports on a water channel socket, a quick connection can be achieved through the water channel socket and the water channel connector arranged on the optical module 200, thereby improving the plug-in and unplugging efficiency of the optical module 200 and the test water channel. The present embodiment does not limit the specific plug-in form of the water channel socket and the water channel connector, as long as the function of plug-in water can be achieved.

[0044] In some embodiments, the optical module test water circuit 100 also includes two three-way valves 3, a ventilation line 52 and an exhaust line 51. The two three-way valves 3 are respectively arranged in the water supply line 11 and the return line 12. The three-way valves 3 also have a branch connector 31; the ventilation line 52 and the exhaust line 51 are respectively connected to the branch connectors 31 of the two three-way valves 3.

[0045] Among them, the three-way valve 3 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 31, and the other two ports are respectively used to be connected in series with the water supply pipe 11 or the return pipe 12; among them, the ventilation pipe 52 and the exhaust pipe 51 in this embodiment can be connected to one of the water supply pipe 11 and the return pipe 12 respectively through the three-way valve 3, and this embodiment does not limit its specific connection relationship.

[0046] It is worth mentioning that a four-way valve or a five-way valve which only uses three ports or three passages thereof should also be considered as being within the protection scope of the three-way valve 3 in this embodiment.

[0047] According to the above technical scheme, three-way valves 3 are respectively provided on the water supply pipeline 11 and the return pipeline 12, and the ventilation pipeline 52 and the exhaust pipeline 51 are connected through the branch connector 31 on the three-way valve 3. After the water flow test of the optical module 200 is completed, the water flow of the water supply pipeline 11 is blocked by controlling the channel change in the three-way valve 3, and the ventilation pipeline 52 can be ventilated to the water supply pipeline 11 or the return pipeline 12. The airflow can discharge the cooling water in the optical module 200 to the exhaust pipeline 51 through the flow path switching structure 2, and then the connection between the optical module 200 and the module water flow group is disconnected to ensure that the cooling water in the optical module 200 is emptied.

[0048] Specifically, in some embodiments, the ventilation pipeline 52 is connected to the water supply pipeline 11 through the three-way valve 3, and the exhaust pipeline 51 is connected to the return water pipeline 12 through the three-way valve 3, that is, the ventilation direction in the pipeline is consistent with the water flow direction.

[0049] Furthermore, in some embodiments, a one-way valve 7 is provided on the ventilation line 52 and / or the exhaust line 51 .

[0050] Among them, the one-way exhaust direction of the one-way valve 7 should be from the ventilation line 52 to the exhaust line 51. The above two parallel technical features "a one-way valve 7 is provided on the ventilation line 52" and "a one-way valve 7 is provided on the exhaust line 51" can be set either 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 reversely entering the circulation flow path 1, the flow path switching structure 2 and the cooling water path of the optical module 200 through the exhaust line 51.

[0051] In some embodiments, the optical module test water circuit 100 also includes two three-way valves 3, a ventilation line 52 and a pressure measuring line 6. The two three-way valves 3 are respectively arranged in the water supply line 11 and the return line 12. The three-way valves 3 also have a branch connector 31; the ventilation line 52 and the pressure measuring line 6 are respectively connected to the branch connectors 31 of the two three-way valves 3.

[0052] The function of the pressure measuring pipeline 6 is to measure the pressure of the gas passing 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.

[0053] According to the above technical scheme, the gas pressure before water is passed through the entire optical module test water circuit 100 can be measured through the pressure measuring pipeline 6, that is, the airtightness test function can be realized, and at least the airtightness of the connection between the optical module 200 and the two second water ports 22a of the module water passing group can be ensured, providing reliable guarantee for the subsequent introduction of cooling water.

[0054] Specifically, in some embodiments, a water mist separator 61 and a pressure gauge 62 are provided on the pressure measuring pipeline 6 .

[0055] Among them, the water mist separator 61 is arranged upstream of the barometer 62. Even if there is residual moisture in the circulating flow path 1 and the flow path switching structure 2, it enters the pressure measuring pipeline 6 along with the gas introduced by the ventilation pipeline 52. Under the water-isolating effect of the water mist separator 61, the water mist in the gas can be separated to prevent the barometer 62 from being damaged by moisture.

[0056] In other embodiments, the optical module test water circuit 100 also includes an exhaust pipeline 51 and a passage switching structure 4. The exhaust pipeline 51 and the pressure measuring pipeline 6 are connected in parallel to the corresponding branch connector 31 through the passage switching structure 4. The passage switching structure 4 can switch the exhaust pipeline 51 and the pressure measuring pipeline 6 to be connected to the branch connector 31.

[0057] It should be noted that the passage switching structure 4 has the same structural form and working principle as the above-mentioned flow path switching structure 2. It can selectively connect one of the parallel exhaust pipes 51 and pressure measuring pipes 6 to the branch connector 31 of the corresponding three-way valve 3, thereby realizing adaptive switching of the air tightness test function and the drainage function.

[0058] Specifically, see Figure 1 , the passage switching structure 4 can be set as a three-way valve.

[0059] In some embodiments, a flow meter 8 is provided on the water supply pipeline 11 and / or the water return pipeline 12 .

[0060] By setting the flow meter 8, the cooling water flow rate in the circulation flow path 1 can be monitored in real time to ensure that the optical module 200 completes the test work under the preset cooling water flow rate.

[0061] Specifically, the flow meter 8 is arranged on the return water pipeline 12, and the flow meter 8 can be selectively arranged as a temperature measuring flow meter.

[0062] In some embodiments, a normally closed solenoid valve 9 is provided on the water supply pipeline 11 and / or the water return pipeline 12 .

[0063] By setting the normally closed solenoid valve 9, when cooling water is not needed, the normally closed solenoid valve 9 is automatically disconnected, which can reduce the residual cooling water in the circulation flow path 1 and the flow path switching structure 2 and avoid the waste of cooling water.

[0064] Combined with the flow meter 8 in the above embodiment, the normally closed solenoid valve 9 can accurately control the circulation of cooling water to ensure the stability and consistency of the water supply flow.

[0065] Specifically, the multi-way valve 21 and the three-way valve 3 mentioned in the embodiment of the utility model can be partially set as solenoid valves, which can be automatically opened and closed through electrical control.

[0066] The utility model also proposes an optical module testing system, which includes an optical module testing water circuit 100. The specific structure of the optical module testing water circuit 100 refers to the above-mentioned embodiment. Since the optical module testing system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0067] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
