[0046] Currently, the performance testing process for pump structures on production lines mostly involves manually inspecting each pump structure individually using a combination of components. This existing testing method has several drawbacks: First, manually inspecting all production components places excessively high demands on the technical skills of the personnel; second, operator efficiency is low, as only one component can be inspected at a time, resulting in low testing efficiency; third, the testing equipment's capabilities are not comprehensive enough.

[0047] This invention proposes a pump performance testing device to solve the above problems.

[0048] Please see Figures 1 to 2 In one embodiment of this utility model, the pump performance testing equipment 100 includes a frame 1, two testing structures 2, and a loading / unloading structure 3. The frame 1 has a working end with two testing positions formed along a first direction. The two testing structures 2 are respectively installed on the two testing positions. Each testing structure 2 includes an integrating sphere structure 21 and a fixing structure 22 arranged in a second direction, the fixing structure 22 being used to fix the pump carrier. The loading / unloading structure 3 includes two racks 31 and a robotic arm structure 32. The two racks 31 are alternately arranged along the first direction at one end of the frame 1 in the second direction to accommodate the pump carrier, and an installation area is formed between the two racks 31. The robotic arm structure 32 is located in the installation area for transferring the pump carrier. Both the first direction and the second direction are horizontal planes.

[0049] like Figure 1As shown, the first direction and the second direction are preferably two mutually perpendicular directions in the horizontal plane. Unlike the conventional test structure 2, the test equipment provided in the above embodiment includes two components, which, together with the robotic arm structure 32, enable efficient testing of the two test structures 2 without waiting time. Specifically, the pump carrier material to be tested is stacked on the two material racks 31. A corresponding clamping structure 321 is provided on the output end of the robotic arm structure 32. During loading and unloading, the clamping structure 321 can clamp the two ends of the pump carrier in the width direction, thereby removing the pump carrier from the fixed structure 22 or placing it on the fixed structure 22.

[0050] In terms of specific structure, the two material racks 31 can be respectively configured as an upper material rack 31 and a lower material rack 31. The two material racks 31 are located at one end of the frame 1 in the second direction, and the robotic arm structure 32 is located in the middle of the two material racks 31. This is to allow the robotic arm structure 32 to better pick up and place the carrier structures on the two material racks 31, and to allow the robotic arm structure 32 to extend above the two fixed structures 22 at the same time to perform pick-up and place operations.

[0051] During actual testing, the robotic arm structure 32 places the pump carrier on the loading rack 31 onto the fixed structure 22 for fixation. After fixation, the fiber optic output end of the pump carrier is synchronously aligned with the injection port of the integrating sphere. During testing, materials are sequentially loaded onto the two fixed structures 22, and the two integrating sphere structures 21 simultaneously test the pump structure. This structural layout enables the entire test structure 2 to achieve efficient testing results, and the entire structure is compact and reasonable, effectively replacing manual labor to achieve efficient production.

[0052] The integrating sphere test structure 2 described above is a commonly used structure in fiber optic testing. The integrating sphere is a hollow, complete open-cavity sphere with its inner wall coated with a white diffuse reflective material. Several windows are opened on the inner wall of the sphere for light entry and placement of light receivers, etc. Each point on the inner wall of the integrating sphere carries the characteristics of the incident light signal; by measuring the diffuse light on the sphere wall, the total illuminance value can be calculated. The integrating sphere test structure 2 described above is basic common knowledge in this field and will not be elaborated further here.

[0053] It is conceivable that the two test structures 2 in the above structure need to cooperate with the robotic arm structure 32 for loading and unloading to complete the entire testing process. The robotic arm structure 32 has a certain time difference in loading and unloading on the two fixed structures 22. When the pump structure on the first fixed structure 22 is being tested, the robotic arm structure 32 simultaneously completes the loading operation on the other fixed structure 22 during this time period. When the latter pump structure is being tested, the former fixed structure 22 performs unloading and loading. In actual production, the robotic arm structure 32 can be set according to the actual testing time to ensure that the two test structures 2 are in a fully loaded production state as much as possible, thereby further improving the testing efficiency of the entire equipment.

[0054] During the testing process in conjunction with the integrating sphere structure 21, the pump structure generates a significant amount of heat. To monitor the temperature of its internal components during the testing process, the test structure 2 further includes a temperature measurement structure 5. The temperature measurement structure 5 includes a temperature camera 53, which is mounted on the frame 1 and has a travel distance in a first direction and a second direction.

[0055] When performing temperature measurements, the top cover of the pump structure needs to be opened. For ease of operation, before formal assembly, the cover of the pump structure is only placed over the open end of its housing. During actual testing, the robotic arm structure 32 first removes the cover of the pump structure and places it on the working end. Then, the temperature measuring camera 53 moves to a position above the pump structure. The temperature measuring camera 53 is an infrared temperature measuring camera, which can obtain the infrared radiation values ​​of each electrical component within the pump structure, thereby obtaining the actual temperature value of each electrical component. The temperature measuring camera 53 monitors the temperature of each component. When the temperature is too high and an abnormality occurs, it can cut off the power to the entire test structure 2, thereby stopping the test and avoiding greater losses.

[0056] The temperature measuring camera 53 is configured to be position-adjustable because the robotic arm structure 32 moves above the fixed structure 22 during loading and unloading. To avoid interference from the temperature measuring camera 53, it is preferable to configure the temperature measuring camera 53 to be position-adjustable.

[0057] Specifically, in one embodiment of this utility model, such as Figure 1 and Figure 2As shown, the temperature measuring structure 5 further includes a temperature measuring frame 51 and a driving component 52. The temperature measuring frame 51 is mounted on the frame 1 at the midpoint between the fixed structure 22 and the integrating sphere structure 21. The driving component 52 includes a first driving device 521 and a second driving device 522. The first driving device 521 is mounted on the temperature measuring frame 51, and its output end is movably disposed along a first direction. The second driving device 522 is mounted on the output end of the first driving device 521, and its output end is movably disposed along a second direction. The temperature measuring camera 53 is disposed on the output end of the second driving device 522.

[0058] In the above structure, when the first driving device 521 moves, it can drive the second driving device 522 to move in the first direction, and the second driving device 522 can drive the temperature measuring camera 53 to move in the second direction. Therefore, when the two driving devices work simultaneously, the temperature measuring camera 53 can be quickly moved to the position above the pump structure, and when the robotic arm structure 32 is loading and unloading, the temperature measuring camera 53 can be driven to avoid obstacles on the corresponding fixed structure 22. It is conceivable that both the first driving device 521 and the second driving device 522 are linear drive structures 8, which can be configured as linear motors, cylinders, or electric actuators, etc. The specific structure can be set according to the actual production conditions.

[0059] As mentioned above, during the temperature measurement of the pump structure, the top cover of the pump housing needs to be removed. To prevent the top cover from falling off the working end and to ensure its positional stability, a support portion 13 is provided on the working end at a position corresponding to the end of the fixing structure 22 away from the integrating sphere structure 21. This support structure is used to support the top cover of the pump structure.

[0060] In actual operation, after the robotic arm structure 32 removes the upper cover structure, it places it on the placement support structure to support the upper cover. The support surface of the placement support structure is preferably set to be slightly smaller than the inner surface of the upper cover, so that the upper cover can be limited by one end of the placement support part 13 to prevent it from falling.

[0061] In one embodiment of the present invention, the test structure 2 further includes a light leakage detection structure 4; specifically, two light leakage detection structures 4 are configured, and the two light leakage detection structures 4 are respectively configured for two fixed structures 22, so as to detect whether the optical fiber on the pump structure leaks light.

[0062] In the actual testing process, the specific testing procedure is as follows: The photodiode inside the integrating sphere structure 21 converts the optical signal into an electrical signal, and the power value of the device is measured. Simultaneously, the spectrometer inside the integrating sphere structure 21 measures the wavelength of the device. (The power and wavelength measurements of the integrating sphere structure 21 are calibrated using standard parts at each work session. The wavelength of the power meter measured by the integrating sphere structure 21 for each device is compared with that of the standard part to determine whether the device performance is qualified). After the integrating sphere structure 21 completes the measurement, the light leakage detection component performs light leakage detection sampling inspection using attenuation filters to determine whether the device has light leakage defects. After the light leakage detection, the temperature of the components inside the pump is measured using a temperature measurement component.

[0063] Among them, such as Figure 1 and Figure 3 As shown, the fixed structure 22 has a vertical mounting bracket 12 at one end of the integrating sphere; the light leakage detection structure 4 includes a detection end 41 and a support arm structure 42. The detection end 41 integrates a power meter and an attenuator; the support arm structure 42 has a driving end, which is rotatably mounted on the vertical mounting bracket 12, and the detection end 41 is located at the end of the support arm structure 42 away from the driving end.

[0064] In the above structure, when loading or unloading materials, the support arm structure 42 needs to be retracted from above the fixed structure 22. The aforementioned light leakage detection structure 4 is mainly for detecting light leakage of the optical components inside the pump structure. During actual testing, the optical components inside the pump structure generate laser light after being powered on, and the laser light propagates outward through the optical fiber at its end. During detection, the support arm structure 42 moves to a position above one end of the pump structure near the integrating sphere structure 21. At this time, there is no cover plate structure installed on the pump structure. If the internal optical components of the pump structure leak light, the outward-emitted laser light will pass through the detection end 41 and be received by the attenuator and power meter structure on the detection end 41. This determines whether there is light leakage inside the pump structure. It should be noted that the wavelength of laser light is different from that of visible light, so the power meter can distinguish between them when it receives the laser light.

[0065] During installation, a connecting block 421 is provided on the drive end, and two rotating mounting parts 4211 are formed on the connecting block 421; one of the rotating mounting parts 4211 is connected to the vertical mounting frame 12; the light leakage detection structure 4 also includes a flip drive cylinder 43, and a connecting rod 431 is provided on the output end of the flip drive cylinder 43 and rotatably connected thereto, and the other end of the connecting rod 431 is rotatably connected to the other rotating mounting part 4211.

[0066] like Figure 1 , Figure 3As shown, when the output end of the tilting drive cylinder 43 retracts, it pulls one end of the connecting block 421 to rotate via the connecting rod 431. During the rotation of this end on the vertical mounting frame 12, it simultaneously drives the support arm structure 42 to rotate, thereby allowing the detection end 41 to move upwards. This clears the space above the fixed structure 22, improving the ease of loading and unloading the robotic arm structure 32. When the output end of the tilting cylinder moves upwards, it drives one end of the support arm structure 42 to move above the fixed structure 22, thus enabling the detection of light leakage.

[0067] In one embodiment of this utility model, the fixing structure 22 includes a support base 221, a water-cooled plate structure 222, and a positioning structure 223. The support base 221 is mounted on the working end; the water-cooled plate structure 222 is disposed on the support frame to support the pump carrier; the positioning structure 223 includes multiple positioning posts, all of which are mounted on the support base 221, with their upward ends extending above the upper surface of the water-cooled plate structure 222, for limiting and fixing the pump carrier.

[0068] As mentioned above, the pump structure generates a large amount of heat during testing. If this heat cannot be dissipated in time, it will affect the performance of the internal components to some extent. Therefore, a corresponding cooling structure is usually installed on the fixed structure 22 to cool it down. In the above embodiment, the cooling structure is a water-cooled plate structure 222. As the name suggests, the water-cooled plate structure 222 uses low-temperature water to cool the pump structure. Specifically, the pump structure is fixedly installed on the pump carrier, which is placed on the upper surface of the water-cooled plate structure 222 via the robotic arm structure 32. The water-cooled plate structure 222 is connected to circulating cold water at a low temperature, which can effectively remove the heat from the pump carrier. The water-cooled plate structure 222 is frequently used in mechanical production. Its specific working method is generally to remove the heat from the heat-generating components through circulating cooling liquid. Its specific structure will not be described in detail here.

[0069] In order to ensure the cooling effect of the water-cooled plate structure 222, the pump carrier needs to be fixedly installed on the water-cooled plate. In the above structure, after the robotic arm structure 32 places the pump carrier on the water-cooled plate structure 222, the multiple positioning columns on the support base 221 will guide the pump carrier so that the pump carrier can be placed in the enclosed area formed by the multiple positioning columns.

[0070] Furthermore, to improve the contact effect between the pump carrier and the water-cooled plate structure 222, thereby ensuring efficient heat transfer, the fixing structure 22 also includes a pressing structure 23. Wherein, as Figure 1 and Figure 4 As shown, the working end is provided with a guide rail 11, which is located at one end of the support base 221 in a first direction and extends along the first direction; the pressing structure 23 includes a mounting plate portion 9231 and a pressing portion 232. The mounting plate portion 9231 is movably mounted on the guide rail 11 in the first direction, and a pressing portion mounting bracket 2311 is provided on the mounting plate portion 9231; the pressing portion 232 includes a pressing cylinder 2321 and a pressing rod 2322, the pressing cylinder 2321 is mounted on the pressing portion mounting bracket 2311, and the pressing rod 2322 is mounted on the output end of the pressing cylinder 2321, with its end extending upward toward the support base 221.

[0071] After the pump carrier is placed on the water-cooled plate structure 222, the mounting part 4211 moves along the guide rail 11 towards the water-cooled plate structure 222. This causes one end of the pressure rod 2322 to move to a position above the pump carrier. Once one end of the pressure rod 2322 is in place, the pressing cylinder 2321 drives the pressure rod 2322 downward, thereby pressing and fixing the pump carrier onto the water-cooled plate structure 222 through its end.

[0072] It is conceivable that the movement of the mounting plate 9231 can be driven by a cylinder or an electric actuator. In actual installation, a suitable driving component 52 can be selected for use according to the actual situation.

[0073] As described above, the pump carrier is cooled by the water-cooled plate structure 222. To ensure effective heat transfer, the upper surface of part of the water-cooled plate structure 222 can be configured as a water storage structure to remove air between the pump carrier end and the water-cooled plate, thereby maximizing heat transfer efficiency. In this case, to ensure the pump carrier remains dry after testing, a wiping table 311 is provided on the unloading rack 31 or the loading rack 31. The upper part of the wiping table 311 is made of absorbent material, which effectively removes cooling water adhering to the pump carrier when it is placed on it.

[0074] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
