[0034] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] The following first describes in detail the detection and alignment device 100 according to the embodiment of the present application with reference to the drawings.

[0036] like Figures 1 to 3 As shown, the detection and alignment device 100 according to the embodiment of the present application includes: a detection module 10 and a motion module 20.

[0037] Specifically, the detection and alignment device 100 is provided with a detection station, the detection module 10 is arranged on one side of the detection station, the motion module 20 is provided with an image module 21 and a carrying module 22, and the motion module 20 can be switched between a first state and a second state; wherein, the image module 21 is suitable for providing a detection image, and the carrying module 22 is suitable for carrying a display screen 220 of the optical module 200; when the motion module 20 is in the first state, the image module 21 corresponds to the position of the detection station, and the detection module 10 cooperates with the image module 21 to detect the lens assembly 210 located at the detection station; when the motion module 20 is in the second state, the carrying module 22 corresponds to the position of the detection station, so that the detection module 10 can detect the optical module 200 formed by the lens assembly 210 and the display screen 220, and the motion module 20 can adjust the position of the display screen 220 according to the detection result of the optical module 200 to align the optical module 200.

[0038] In other words, if Figures 1 to 3As shown, the detection and alignment device 100 according to the embodiment of the present application is mainly composed of a detection module 10 and a motion module 20. Specifically, the detection and alignment device 100 is provided with a detection station, the detection module 10 is installed on one side of the detection station (for example, the upper side of the detection station), and the motion module 20 includes two functional modules, namely an image module 21 and a carrying module 22, the image module 21 is used to provide a detection image, and the carrying module 22 is used to carry the display screen 220 of the optical module 200.

[0039] like Figures 1 to 3 As shown, in this embodiment, the motion module 20 has a first state and a second state, and the motion module 20 can switch between the two states. When the motion module 20 is in the first state, the carrier module 22 is staggered with the detection station, and the image module 21 corresponds to the position of the detection station. The lens assembly 210 located at the detection station can be detected by the cooperation of the detection module 10 and the image module 21, thereby realizing the function of detecting the lens assembly 210.

[0040] like Figure 2 and Figure 3 As shown, when the moving module 20 is in the second state, the image module 21 is offset from the detection station, the carrying module 22 corresponds to the position of the detection station, the display screen 220 carried by the carrying module 22 and the lens assembly 210 of the detection station constitute the optical module 200 (i.e., the unassembled optical module 200). In this state, the detection module 10 can detect the optical module 200, and the moving module 20 can adjust the position of the carrying module 22 according to the detection result of the optical module 200, so that the relative position of the display screen 220 and the lens assembly 210 changes, thereby realizing the alignment function of the optical module 200 before assembly.

[0041] It should be noted that the lens assembly 210 of the inspection station is loaded and unloaded from the loading station to the inspection station by an external loading and unloading structure, for example, by a robotic arm, and fixed, so that the lens assembly 210 is located at the inspection station. When the lens assembly 210 is unqualified, the robotic arm can be used to move the lens assembly 210 out of the inspection station, or after the optical module 200 is assembled, the robotic arm can be used to move the assembled optical module 200 out of the inspection station.

[0042] Therefore, according to the detection and alignment device 100 provided in this embodiment, by setting a motion module 20 that can switch between a first state and a second state, the detection module 10 can not only independently detect the lens assembly 210, but also detect the optical module 200, and the position of the display screen 220 can be adjusted according to the detection result through the motion module 20, so as to realize the alignment of the optical module 200, so that the detection of the lens assembly 210 and the alignment of the optical module 200 can be completed on the same device, thereby improving the coordination effect and production efficiency between the two process steps.

[0043] According to one embodiment of the present application, the motion module 20 also includes: a motion platform 23, the motion platform 23 is suitable for carrying the image module 21 or the carrying module 22, and adjusting the position of the image module 21 or the carrying module 22; a switching module 24, the switching module 24 is suitable for switching the position of the image module 21 and the carrying module 22, so that the motion module 20 can switch between the first state and the second state.

[0044] That is to say, Figures 1 to 3 As shown, according to the embodiment of the present application, the motion module 20 mainly includes an image module 21, a carrying module 22, a motion platform 23 and a switching module 24, wherein the motion platform 23 can be a multi-degree-of-freedom motion platform, such as a six-degree-of-freedom motion platform, and the motion platform 23 can be arranged below the detection station, and the image module 21 or the carrying module 22 can be carried by the motion platform 23. Specifically, the switching module 24 can switch the positions of the image module 21 and the carrier module 22. For example, when the lens assembly 210 needs to be inspected, if the carrier module 22 corresponds to the position of the inspection station, the switching module 24 can be used to swap the positions of the image module 21 and the carrier module 22 so that the image module 21 corresponds to the position of the inspection station, and the motion platform 23 can control the activity of the image module 21 according to the inspection requirements; when the optical module 200 is inspected next time, the switching module 24 can be used to swap the positions of the image module 21 and the carrier module 22 so that the carrier module 22 corresponds to the position of the inspection station, and the motion platform 23 can control the activity of the carrier module 22 according to the inspection requirements, and the motion platform 23 can drive the carrier module 22 according to the inspection results to adjust the position of the display screen 220.

[0045] In this embodiment, the modular motion module 20 allows each module to be maintained independently, which simplifies the maintenance and repair process of the device and reduces maintenance costs. At the same time, when changing the product type, only the product tooling needs to be redesigned, and other modules can remain unchanged, thereby effectively improving the reuse rate of the device.

[0046] In some embodiments of the present application, the switching module 24 includes: a transmission member, a first connecting member is provided at the first end of the transmission member, a second connecting member is provided at the second end of the transmission member, the first connecting member is suitable for being controllably connected to the image module 21, and the second connecting member is suitable for being controllably connected to the carrying module 22; a driving member, the driving member is connected to the transmission member, and the driving member is suitable for driving the transmission member to move between a first position and a second position; when the transmission member is in the first position, the motion module 20 is in a first state, and when the transmission member is in the second position, the motion module 20 is in a second state.

[0047] Specifically, the switching module 24 is mainly composed of a transmission member and a driving member, wherein the transmission member has a first end and a second end arranged oppositely, the first end of the transmission member is installed with a first connecting member, and the second end of the transmission member is installed with a second connecting member, and both the first connecting member and the second connecting member can be electric clamps. The first connecting member can be controllably connected to the image module 21, that is, the first connecting member can clamp the image module 21 to achieve connection according to needs, and can also release the image module 21 to achieve separation according to needs. In the separated state, the motion platform 23 can drive the image module 21 to move to adjust the position of the image module 21; the second connecting member can be controllably connected to the carrier module 22, that is, the second connecting member can clamp the carrier module 22 to achieve connection according to needs, and can also release the carrier module 22 to achieve separation according to needs. In the separated state, the motion platform 23 can drive the carrier module 22 to move to adjust the position of the display screen 220.

[0048] The output end of the driving member is connected to the transmission member, and the driving member can drive the transmission member to move between the first position and the second position. When the transmission member is in the first position, the motion module 20 is in the first state, the image module 21 corresponds to the position of the detection station, the first connecting member can be separated from the image module 21, and the image module 21 can be driven to move by the motion module 20 to provide the required detection image for the detection module 10.

[0049] When the motion module 20 needs to be switched to the second state, the first connecting member clamps the image module 21, the second connecting member clamps the carrying module 22, and the driving member drives the transmission member to move from the first position to the second position. At this time, the carrying module 22 corresponds to the position of the detection station, and the second connecting member clamps the carrying module 22. The second connecting member can be separated from the carrying module 22. The carrying module 22 can be driven to move by the motion module 20 to provide the required detection image for the detection module 10, and the carrying module 22 can be driven to move according to the detection structure to align the optical module 200.

[0050] In this embodiment, the transmission member can drive the image module 21 and the carrier module 22 to move simultaneously, which can effectively improve the state switching process of the motion module 20, thereby effectively improving the production efficiency.

[0051] According to one embodiment of the present application, the driving member is suitable for driving the transmission member to rotate between a first position and a second position.

[0052] In this embodiment, the driving member can be a motor, and the output end of the motor can be connected to the part between the first end and the second end of the transmission member, so that the driving member can drive the transmission member to rotate between the first position and the second position, thereby eliminating the need to occupy a larger space in a single direction.

[0053] In some embodiments of the present application, the image module 21 includes: a target carrier 211 and a target body 212, the target body 212 is detachably disposed on the target carrier 211; a light source 213, the light source 213 is disposed between the target carrier 211 and the target body 212, and the target carrier 211 is suitable for emitting light toward the target body 212.

[0054] In other words, the image module 21 is mainly composed of a target carrier 211, a target body 212 and a light source 213, wherein the target carrier 211 can be configured into a tray shape, the target body 212 is engraved with a hollow pattern required for detection, and the target body 212 is installed on the target carrier 211. During detection, the upper side of the target body 212 faces the detection station to provide the detection pattern required for detection for the lens assembly 210 of the detection station; the light source 213 can be a highly uniform planar light source 213, the light source 213 can be installed on the target carrier 211, and the light source 213 is located below the target body 212, and the light source 213 can emit light from below the target body 212 toward the target body 212, and the light can pass through the hollow pattern on the target, so that the detection module 10 can collect a clearer detection pattern.

[0055] Furthermore, the target body 212 and the target carrier 211 are detachably connected together, for example, the target body 212 and the target carrier 211 are detachably connected together by screws, a snap-on structure or a clamping structure, so that the target body 212 can be replaced according to usage requirements without replacing the entire image module 21.

[0056] Optionally, the light source 213 and the target carrier 211 are detachably connected together, for example, the light source 213 and the target carrier 211 are detachably connected together via screws, a snap-fit ​​structure or a clamping structure.

[0057] According to one embodiment of the present application, the carrying module 22 is configured to controllably fix the display screen 220 .

[0058] Specifically, the carrying module 22 can be formed into a tray structure, and the carrying module 22 is provided with a fixing device for fixing the display screen 220 , thereby effectively preventing the display screen 220 from being displaced during the alignment process, and ensuring the alignment accuracy of the optical module 200 .

[0059] In some embodiments of the present application, the motion platform 23 is configured to be able to controllably fix the image module 21 or the carrier module 22 .

[0060] That is to say, the motion platform 23 is provided with a fixing structure for fixing the image module 21 or the carrier module 22, thereby effectively preventing the image module 21 or the carrier module 22 from being displaced during the movement of the motion platform 23, and ensuring the alignment accuracy of the optical module 200.

[0061] According to one embodiment of the present application, the motion platform 23 is configured to fix the image module 21 or the carrier module 22 by adsorption or clamping.

[0062] Specifically, a plurality of negative pressure adsorption holes are provided on the bearing surface of the moving platform 23, so that the moving platform 23 can fix the image module 21 or the bearing module 22 by adsorption; or, a clamping structure is provided on the bearing surface of the moving platform 23, so that the moving platform 23 can fix the image module 21 or the bearing module 22 by clamping; thereby, the displacement of the image module 21 or the bearing module 22 during the movement of the moving platform 23 can be effectively avoided, and the alignment accuracy of the optical module 200 can be ensured.

[0063] In some embodiments of the present application, the detection module 10 includes at least one detection module 11, and the detection module 11 is used to detect imaging quality data and generate a TF curve.

[0064] That is to say, the detection module 10 has one or more detection modules 11, and the following is a specific description taking one detection module 11 as an example. The detection module 11 is a field of view camera module, and the detection module 11 mainly includes a camera, and the camera is provided with a controller, and the lens of the camera faces the detection station. During the detection, the motion platform 23 drives the image module 21 or the carrier module 22 to move along the axis of the camera. In this process, the detection module 11 can detect the imaging quality data of the lens assembly 210 or the optical module 200, and generate a TF (Through Focus) curve.

[0065] Therefore, whether the lens assembly 210 is qualified can be confirmed based on the imaging quality data and TF curve of the lens assembly 210, and the target position of the display screen 220 can be calculated based on the imaging quality data and TF curve of the optical module 200, which can ensure the accuracy of the detection of the lens assembly 210 and the alignment accuracy of the optical module 200.

[0066] It should be noted that when the number of the detection module 11 is one, the alignment of the lens with a smaller FOV can be satisfied, and the detection module 11 adopts a large field of view camera to ensure the detection accuracy.

[0067] In some examples of the present application, the camera is an industrial camera, such as a CCD camera.

[0068] According to one embodiment of the present application, the detection module 10 includes: multiple detection modules 11 and a dome 12, the inner wall of the dome 12 faces the detection station, the multiple detection modules 11 are arranged on the inner wall of the dome 12, one detection module 11 is located in the center of the dome 12, and the remaining detection modules 10 are arranged around the central detection module 10.

[0069] Specifically, the detection module 10 according to the embodiment of the present application mainly includes a plurality of detection modules 11 and a dome 12. The number of the detection modules 11 can be determined according to actual needs. The recessed portion of the dome 12 faces the detection station, so that the inner wall of the dome 12 faces the detection station. In the embodiment, the number of the detection modules 11 is five, one of which is installed at the central position of the inner wall of the dome 12 as a central field of view detection module 11 to detect the lens assembly 210 or the optical module 200 in the central field of view, and the remaining four detection modules 11 are installed on the inner wall of the dome 12, and the four detection modules 11 are located at the periphery of the central field of view detection module 11, that is, the four detection modules 11 are located at the edge of the dome 12 as edge field of view detection modules 11 to detect the optical module 200 in four edge fields of view.

[0070] Therefore, according to the detection and alignment device 100 of the embodiment of the present application, multiple detection modules 11 can be set to perform detection in multiple fields of view of the lens assembly 210 or the optical module 200, which can effectively ensure the accuracy of the detection of the lens assembly 210 and the alignment accuracy of the optical module 200. Moreover, when one of the detection modules 11 is damaged, the detection and alignment device 100 can still be used normally, which effectively improves the reliability of the alignment device.

[0071] When the detection and alignment device 100 according to the embodiment of the present application is used, the first step is to use a loading structure such as a robotic arm to load the lens assembly 210 to be measured and assembled to the detection station, and place the display screen 220 on the carrying module 22; the second step is to use the switching module 24 to place the image module 21 on the motion platform 23, and light up the light source 213; the third step is that the motion platform 23 drives the image module 21 to move along the axial direction of the central field of view detection module 11 to scan, and the imaging quality of the lens assembly 210 is measured by the detection module 11, and a TF curve is generated; the fourth step is to move the image module 21 to the optimal imaging position of the corresponding field of view through the motion platform 23, and perform MTF measurement to determine Whether the lens assembly 210 is qualified, if qualified, proceed to the next step; the fifth step, the carrying module 22 carrying the display screen 220 is placed on the moving platform 23 through the switching module 24, and the display screen 220 is glued and lit; the sixth step, the moving platform 23 drives the carrying module 22 to move along the axial direction of the central field detection module 11, and scans, and measures the imaging quality of the optical module 200 through the detection module 11, and generates a TF curve; the seventh step, according to the algorithm calculation results, the display screen 220 is moved to the optimal imaging position through the moving platform 23, and UV curing is performed, and then the MTF value is re-measured; the eighth step, the optical module 200 after the lens assembly 210 and the display screen 220 are assembled is cut.

[0072] In summary, according to the detection and alignment device 100 provided in this embodiment, by setting a motion module 20 that can switch between a first state and a second state, the detection module 10 can not only independently detect the lens assembly 210, but also detect the optical module 200, and the motion module 20 can adjust the position of the display screen 220 according to the detection result, so as to realize the alignment of the optical module 200, so that the detection of the lens assembly 210 and the alignment of the optical module 200 can be completed on the same device, thereby improving the coordination effect and production efficiency between the two process steps.
