Description

Technical Field

[0001] This application relates to the field of optical equipment technology, and more specifically to a power-on testing machine for a lens module. Background Technology

[0002] A lens module, such as the aperture, is a device used to control the amount of light passing through the lens and entering the camera's sensor. The amount of light entering the lens can be adjusted by adjusting the lens module.

[0003] Lens modules need to undergo power-on testing during production. Currently, automated equipment for power-on testing of lens modules, such as the Chinese patent with application publication number CN118984377A (hereinafter referred to as the existing patent), discloses a camera aperture testing device.

[0004] In existing patents, camera aperture detection equipment includes a workstation turntable, an installation robot module, a detection robot module, a disassembly / installation robot module, a unloading robot module, a transfer station, a second transfer module, and a detection module. The horizontal rotation of the workstation turntable moves the aperture sequentially from the loading station to the installation station, detection station, disassembly / installation station, and unloading station. The installation robot module installs the aperture to be detected onto the fixture at the installation station. The detection robot module moves the fixture with the aperture installed at the detection station to the transfer station and then moves the fixture with the detected aperture installed at the transfer station to the detection station. The second transfer module transfers the aperture between the transfer station and the detection module, and the detection module detects the aperture. The disassembly / installation robot module disassembles the aperture from the fixture at the disassembly / installation station. The unloading robot module moves the aperture from the unloading station to the loading / unloading assembly line module.

[0005] As can be seen in existing patents, in order to detect the aperture, the aperture's position is moved multiple times during the process from its installation on the fixture to its removal from the fixture. For example, the aperture's position is sequentially moved from the workstation turntable to the detection robot module, the transfer station, the second transfer module, the detection module, the second transfer module, the transfer station, the detection robot module, and the workstation turntable. Thus, in existing patents, the camera aperture detection equipment is not only bulky, but the multiple movements of the lens module also increase the risk of damage to the lens module.

[0006] Clearly, miniaturizing automated equipment for power-on testing of lens modules to reduce the number of times lens modules are transferred and lower the risk of damage to lens modules remains a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, in order to solve the above-mentioned technical problems, this application provides a power-on testing machine for lens modules, which includes a frame, a flipping device, a holding device, a power-on conductor and a first vision component;

[0008] The pressing device, the energized conductor, the flipping device, and the first vision assembly are located at the same station on the frame;

[0009] The flipping device uses a vertical flipping operation to switch the lens module between the material changing posture and the inspection posture;

[0010] The conductive component is used to conduct electricity to the lens module;

[0011] The holding device is used to hold the lens module against the flipping device when the flipping device is performing a vertical flipping operation;

[0012] The first vision component is used to perform visual inspection of the lens module in the detection posture.

[0013] Beneficial effects: Unlike existing technologies, this application facilitates the replacement of lens modules requiring power-on testing in the material-changing posture. In the testing posture, the first vision component can detect the working status of the lens module. Since the material-changing and testing postures of the lens module are switched by a flipping device, the lens module remains in the flipping device without needing to be moved when switching between the two postures. This enables miniaturization of the power-on testing machine, reducing the number of lens module transfers and lowering the risk of lens module damage. Attached Figure Description

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] It should be noted that the terms "first," "second," "third," "fourth," "fifth," and "sixth," etc., used in the embodiments of the present invention are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth," etc., may explicitly or implicitly include at least one of that feature.

[0042] It should be noted that, in the following text, "vertical" refers to the direction of extension of the plumb line. Vertical, horizontal, and longitudinal directions can be perpendicular to each other, but are not limited to this.

[0043] Please combine Figures 1-3 See also Figures 4-9 As shown, the power-on testing machine 10 of the lens module 20 of this application includes a frame 100, a flipping device 200, a holding device 300, a power-conducting conductor 330, and a first vision component 400.

[0044] The holding device 300, the energized conductor 330, the flipping device 200, and the first vision component 400 are disposed at the same station on the frame 100. The flipping device 200 drives the lens module 20 to switch between a material changing posture and an inspection posture through a vertical Z-flip operation. The energized conductor 330 is used to electrically conduct electricity to the lens module 20. The holding device 300 is used to hold the lens module 20 against the flipping device 200 when the flipping device 200 performs a vertical Z-flip operation. The first vision component 400 is used to perform visual inspection on the lens module 20 in the inspection posture.

[0045] In this way, the lens module 20, which requires power-on testing, can be easily replaced in the material-changing posture. In the testing posture, the first vision component 400 can detect the working status of the lens module 20. Since the material-changing posture and testing posture of the lens module 20 are switched by the flipping device 200, the lens module 20 remains within the flipping device 200 without needing to be moved when switching between the material-changing and testing postures. This allows for miniaturization of the power-on testing machine 10, reducing the number of times the lens module 20 needs to be moved and lowering the risk of damage to the lens module 20.

[0046] Among them, combined Figure 2 and Figure 3 See Figure 4 In the material changing posture, the flipping device 200 can support the lens module 20 so that when the holding device 300 releases the lens module 20, the lens module 20 can be detachably stopped on the flipping device 200. Combined with Figures 2-6 See Figure 8 In the detection posture, the lens module 20 faces the first vision component 400, and the energized conductor 330 is used to energize the lens module 20 so that the first vision component 400 can detect the working state of the lens module 20.

[0047] The term "detachable and stationary on the flip device 200" means that the lens module 20 can overcome the gravity of the lens module 20 under the support of the flip device 200 and be stationary on the flip device 200. However, the lens module 20 can be detached from or stationary on the flip device 200 by moving the lens module 20.

[0048] In this manner, when the holding device 300 releases the lens module 20 in the material changing posture, the lens module 20 can be detachably placed on the flipping device 200. This facilitates the replacement of the lens module 20 requiring power-on testing in the material changing posture. In the testing posture, the first vision component 400 can detect the operating status of the lens module 20. Since the material changing posture and testing posture of the lens module 20 are switched by the flipping device 200, the lens module 20 remains in the flipping device 200 without needing to be moved when switching between the material changing posture and the testing posture. This enables miniaturization of the power-on testing machine 10, reduces the number of times the lens module 20 is moved, and lowers the risk of damage to the lens module 20.

[0049] It should be noted that the lens module 20 is not limited to the aperture. In this way, the first vision component 400 captures the opening and closing state of the aperture blades when the aperture is powered on, so as to detect the tooling status of the lens module 20.

[0050] Optionally, combined Figures 1-3 See Figures 4-8 The holding device 300 includes a telescopic device 310 and a holding arm 320.

[0051] A telescopic device 310 is disposed on the flipping device 200, and a holding arm 320 is disposed on the telescopic device 310. The telescopic device 310 is used to drive the holding arm 320 to move relative to the flipping device 200 to hold or release the lens module 20. When the flipping device 200 flips the lens module 20 to a material changing position, the side of the first clearance opening 321 facing away from the lens module 20 is positioned upwards. When the flipping device 200 flips the lens module 20 to a detection position, the side of the first clearance opening 321 facing away from the lens module 20 is positioned towards the first vision component 400.

[0052] In the manner described above, when the flipping device 200 drives the lens module 20 to flip to the detection posture, the first vision component 400 can capture images of the lens module 20 through the first clearance opening 321.

[0053] It should be noted that in other examples, the holding device 300 can also be replaced by an assembly structure of a mechanical gripper (not shown) and a gripper drive device (not shown). The gripper drive device is located on the flip frame, and the mechanical gripper is located on the gripper drive device. The gripper drive device is used to drive the mechanical gripper to clamp or release the lens module 20. In this other example, in order to facilitate visual inspection of the lens module 20 by the first vision component 400, the mechanical gripper needs to clamp the lens module 20 by clamping the side wall of the lens module 20. However, the side wall of the lens module 20 is approximately annular and not flat, making it difficult to be stably clamped by the mechanical gripper. At this time, the energized conductor 330 and the conductive pin 22 are prone to poor contact due to the loosening of the lens module 20.

[0054] Optionally, combined Figures 1-3 See Figures 4-8 The holding arm 320 is provided with a first clearance opening 321 for exposing the lens module 20. A current-carrying conductor 330 is provided on the holding arm 320 and protrudes from the holding arm 320, and the current-carrying conductor 330 is located on the outer periphery of the first clearance opening 321. When the holding arm 320 holds the lens module 20, the current-carrying conductor 330 contacts the conductive pin 22 of the lens module 20.

[0055] In the above manner, the lens module 20 is held stably by the holding arm 320 and pressed against the flipping device 200, so that when the flipping device 200 performs a vertical Z-flip operation to switch the lens module 20 between the material changing posture and the detection posture, the energized conductor 330 can contact the conductive pin 22 of the lens module 20.

[0056] Optionally, in one example, the energized conductor 330 can be a resilient contact. In another example, the energized conductor can be an energized probe. It should be noted that the end of the energized probe facing away from the lens module 20 can be electrically connected to the control system 800, but is not limited thereto.

[0057] Optionally, the flip angle at which the lens module 20 switches between the material changing posture and the detection posture is the first flip angle. It should be noted that the first flip angle refers to the angle at which the optical axis of the lens module 20 flips. Preferably, this first flip angle is between 60 degrees and 120 degrees. This is because if the first flip angle is less than 60 degrees, the first situation is more likely to occur, while if the first flip angle is greater than 120 degrees, the second situation is more likely to occur.

[0058] In the first scenario, when the lens module 20 switches to the detection posture, the end of the lens module 20 closest to the holding arm 320 is at a higher height relative to the frame. In order for the first vision component 400 to align with the lens module 20 for visual inspection, the overall height of the first vision component 400 also needs to be set higher, which is not conducive to reducing space occupation.

[0059] In the second scenario, when the lens module 20 switches to the detection posture, the end of the lens module 20 closest to the holding arm 320 is lower in height relative to the frame. The inherent height of the first vision component 400 makes it difficult for the first vision component 400 to align with the lens module 20, thus preventing the first vision component 400 from visually detecting the opening and closing state of the fan blades of the lens module 20.

[0060] Optionally, when the flipping device 200 flips the lens module 20 to the material changing posture, the direction in which the end of the first clearance opening 321 facing away from the lens module 20 is the first direction. When the flipping device 200 flips the lens module 20 to the detection posture, the direction in which the end of the first clearance opening 321 facing away from the lens module 20 is the second direction.

[0061] The angle between the first direction and the second direction can be between 60 degrees and 120 degrees, but is not limited to this. For example, the angle between the first direction and the second direction can be 60 degrees, 90 degrees, or 120 degrees, but is not limited to this. Preferably, the angle between the first direction and the second direction can be between 85 degrees and 95 degrees, but is not limited to this. For example, the angle between the first direction and the second direction can be 85 degrees, 90 degrees, or 95 degrees, but is not limited to this.

[0062] Optionally, combined Figures 1-3 See Figures 4-8 , Figure 11 and Figure 12 Looking down at the side of the self-pressure holding arm 320 away from the lens module 20, the first clearance opening 321 includes a first region S1 and a second region S2. The first region S1 is connected to the second region S2, and the second region S2 is connected to the edge of the pressure holding arm 320.

[0063] Optionally, the power-on testing machine 10 includes a transfer device 600, which is disposed on the frame 100. The second region S2 is used to avoid the suction head 630 of the transfer device 600, so that the suction head 630 of the transfer device 600 can pass through the second region S2 to enter and exit the first region S1, so as to move the lens module 20 into or out of the flipping device 200.

[0064] By utilizing the above method, the cooperation between the first region S1 and the second region S2 facilitates the entry and exit of the suction head 630 of the transfer device 600 into the first region S1, thereby enabling easy replacement of the lens module 20 requiring power-on testing during material changing. Furthermore, it offers at least two beneficial effects. First, adding the second region S2 to the first region S1 increases the area of ​​the lens module 20 exposed by the first clearance opening 321. Second, it ensures that the portion of the holding arm 320 located on the outer periphery of the first region S1 has sufficient area to maintain pressure on the lens module 20.

[0065] Optionally, see Figures 4-8 The first clearance opening 321, near the end of the lens module 20, is provided with a module insertion slot 322 corresponding to the first region S1. The module insertion slot 322 is used to insert the end of the lens module 20 near the holding arm 320.

[0066] In this manner, when the holding arm 320 holds the lens module 20, one end of the lens module 20 near the holding arm 320 is inserted into the module insertion slot 322, thereby more stably fixing the position of the lens module 20 on the flipping device 200.

[0067] Among them, combined Figures 1-3 See Figures 4-8 , Figure 11 and Figure 12 The module insertion slot 322 communicates with the second region S2, so that when one end of the lens module 20 near the holding arm 320 is inserted into the module insertion slot 322, the end of the lens module 20 near the holding arm 320 is continuously distributed in the module insertion slot 322 and the second region S2. From the side of the second region S2 near the first region S1 to the edge of the holding arm 320, the second region S2 gradually expands. In this way, it is easier for the suction head 630 of the transfer device 600 to enter the first region S1 through the second region S2.

[0068] Optionally, see Figures 4-8 A pressing block 340 is provided at the connection between the first clearance opening 321 and the module insertion slot 322. The pressing block 340 protrudes from the side wall of the first clearance opening 321. The pressing block 340 is located in the first region S1 and is used to press the end of the lens module 20 near the pressing block 340. In this way, pressing the end of the lens module 20 near the teeth with the pressing block 340 can further improve the stability of the position of the lens module 20 on the flipping device 200, so that the contact position of the lens module 20 on the flipping device 200 is not easily moved when the flipping device 200 drives the lens module 200 to flip.

[0069] Optionally, see Figures 4-8 The flipping device 200 includes a first support 210, a flipping drive device 220, and a flipping frame 230.

[0070] A flip frame 230 is mounted on a first support 210, and a holding device 300 is disposed on the flip frame 230. One end of the flip frame 230 is pivotally connected to the first support 210, and the other end of the flip frame 230 is connected to the first support 210 via a flip drive device 220. The flip frame 230 is provided with a module insertion structure 231 corresponding to the holding device 300. The module insertion structure 231 is used to insert and cooperate with the lens module 20, so that the lens module 20 can be detached and placed on the flip frame 230. The holding device 300 is used to hold or release the lens module 20 relative to the flip device 200. The flip drive device 220 is used to drive the flip frame 230 to perform a vertical Z-rotation operation, so that the lens module 20 can switch between a material changing posture and an inspection posture.

[0071] In this way, since the lens module 20 is inserted and fitted into the module insertion structure 231, when the flipping device 200 drives the lens module 20 to flip to the material replacement posture, the lens module 20 can be pulled out from the module insertion structure 231 so as to replace the lens module 20 that needs to be charged and tested.

[0072] Specifically, see Figures 4-8 The lens module 20 includes a module body 21 and conductive pins 22. When the holding device 300 holds the lens module 20, one end of the module body 21 near the holding arm 320 is inserted into the module insertion slot 322 and abuts against the bottom arm of the module insertion slot 322, and the energized conductor 330 abuts against the conductive pins 22.

[0073] Optionally, see Figures 4-8 The flipping device 200 includes a magnet 240, which is set in accordance with the module limiting structure to provide a magnetic field environment for the lens module 20. Thus, when the holding device 300 holds the lens module 20 and the flipping device 200 flips the lens module 20 to the detection posture, the first vision component 400 can detect the tooling state of the lens module 20 in the magnetic field environment.

[0074] Optionally, see Figures 4-8 The flipping device 200 includes a module fixing base 250, which is disposed on the flipping frame 230. A module insertion structure 231 is disposed on the module fixing base 250. The module fixing base 250 has multiple magnet slots 251 surrounding the module insertion structure 231. Magnets 240 are detachably mounted in the magnet slots 251. Thus, by adding or removing magnets 240 from the magnet slots 251, the strength of the magnetic field in the area where the lens module 20 is located can be changed, facilitating the measurement of the working state of the lens module 20 under different magnetic field strengths.

[0075] It should be noted that in one example, the magnet can be a permanent magnet. In another example, the magnet can be an electromagnet. In yet another example, the flipping device 200 may not include a magnet, in which case the magnet device slot 251 is not provided.

[0076] Optionally, combined Figures 1-3 See Figures 4-8 The flipping device 200 includes a fiber optic sensor 260 and a fiber optic amplifier 270. The fiber optic sensor 260 is disposed on the flipping frame, and its sensing end corresponds to the area of ​​the module holder 250 used to place the lens module 20, for detecting whether a lens module 20 is placed on the module holder 250. The fiber optic sensor 260 is communicatively connected to the control system 800 through the fiber optic amplifier 270. When the fiber optic sensor 260 detects that a lens module 20 is placed on the module holder 250, the control system 800 controls the holding device 300 to hold the lens module 20 and controls the flipping device 200 to flip the lens module 20 to the detection posture. After the lens module 20 is detected, the control system 800 controls the flipping device 200 to flip the lens module 20 to the material changing posture and controls the holding device 300 to release the lens module 20.

[0077] Optionally, combined Figures 1-3 See Figures 4-8 The flipping device 200 and the first vision component 400 are arranged in a horizontal direction. The power-on testing machine 10 includes a first horizontal X-moving device 900, which is disposed on the frame 100. A first support 210 is disposed on the first horizontal X-moving device 900. The first horizontal X-moving device 900 is used to drive the flipping device 200 to move in a horizontal X direction so that the lens module 20 moves closer to or further away from the first vision component 400.

[0078] In the above manner, when the lens module 20 is flipped to the detection posture, the first lateral X-moving device 900 can drive the flipping device 200 to bring the lens module 20 closer to the first vision component 400 so that the first vision component 400 can perform shooting detection on the lens module 20.

[0079] Optionally, combined Figures 1-3 See Figures 4-8 The flip frame 230 is equipped with multiple holding devices 300, which are arranged side by side along the longitudinal direction Y. A first vision component 400 is provided on the frame 100 corresponding to each holding device 300. This allows for simultaneous power-on testing of multiple lens modules 20. Furthermore, multiple flip devices 200 are arranged side by side along the longitudinal direction Y on the frame 100, and each flip device 200 is correspondingly equipped with a holding device 300.

[0080] For example, but not as a limitation, three flipping devices 200 are arranged side by side along the longitudinal direction Y on the frame 100, and two pressing devices 300 are arranged side by side along the longitudinal direction Y on the flipping frame 230 of each flipping device 200, but not limited thereto.

[0081] Optionally, combined Figures 1-3 See Figure 4 , Figure 8 and Figure 9 The first vision component 400 includes a second support 410, a first illumination device 420, and a first camera 430. The second support 410 is mounted on the frame 100, and the first illumination device 420 and the first camera 430 are mounted on the second support 410. The first illumination device 420 is located on the side of the first camera 430 facing the flipping device 200.

[0082] In the above manner, when the lens module 20 is flipped to the detection posture, the first illumination device 420 can provide illumination to the lens module 20 so that the first camera 430 can acquire the image of the lens module 20 exposed through the first illumination device 420 to identify the working state of the lens module 20.

[0083] Optionally, combined Figures 1-3 and Figure 4 See Figures 10-13 The power-on testing machine 10 includes a loading and unloading device 500, a transfer device 600, and a second vision component 700, which are respectively disposed on the frame 100.

[0084] The transfer device 600 includes a shifting device 610, a rotating device 620, and a suction head 630. The suction head 630 is connected to the shifting device 610 via the rotating device 620. The suction head 630 is used to hold the lens module 20 provided by the loading and unloading device 500. The shifting device 610 drives the lens module 20 held by the suction head 630 to move sequentially to the second vision component 700, the flipping device 200, and the loading and unloading device 500.

[0085] The second vision component 700 is used to capture images of the lens module 20 from below the second vision component 700, and the rotating device 620 is used to rotate the lens module 20 in cooperation with the second vision component 700 to correct the position of the conductive pins 22 of the lens module 20.

[0086] In the above manner, with the assistance of the second vision component 700, the rotation device 620 corrects the position of the conductive pin 22 of the lens module 20, so that when the lens module 20 is inserted into the module insertion structure 231, the energized conductor 330 can be aligned and abut against the conductive pin 22.

[0087] Optionally, combined Figures 1-3 See Figures 10-12The shifting device 610 includes a fourth support 611, a second lateral shifting device 612, a first longitudinal shifting device 613, and a first lifting device 614. The fourth support 611 is mounted on the frame 100 and is connected to the first longitudinal shifting device 613 via the second lateral shifting device 612. Both ends of the first longitudinal shifting device 613 can be connected to the second lateral shifting device 612. The first lifting device 614 is mounted on the first longitudinal shifting device 613. A rotating device 620 is mounted on the first lifting device 614.

[0088] The second lateral displacement device 612 is used to move the suction head 630 along the lateral direction X. The first longitudinal displacement device 613 is used to move the suction head 630 along the longitudinal direction Y. The first lifting device 614 is used to lift the suction head 630. Thus, through the cooperation of the second lateral displacement device 612, the first longitudinal displacement device 613, the first lifting device 614, and the rotating device 620, the suction head 630 can move in three-dimensional space and rotate about the vertical direction Z.

[0089] Optionally, combined Figures 1-3 See Figures 10-12 The shifting device 610 includes a mounting plate 615, which is disposed on the first longitudinal shifting device 613, and a first lifting device 614 is disposed on the mounting plate 615. The first lifting device 614, the rotating device 620, and the suction head 630 are arranged sequentially from top to bottom to form a first structural group 30. Multiple first structural groups 30 are arranged side-by-side along the longitudinal direction Y.

[0090] For example, and not as a limitation, four first structural groups 30 are arranged side by side along the longitudinal direction Y. The transfer device 600 thus holds four lens modules 20 via four suction heads 630, thereby reducing the number of cyclic movements of the suction heads 630. Cyclic movement includes cyclic movement between the loading / unloading device 500, the second vision component 700, the flipping device 200, and the loading / unloading device 500.

[0091] Optionally, combined Figures 1-4 See Figures 10-13 The transfer device 600 includes a third vision component 616, which is used to position the lens module 20 on the module bracket plate 60 so that the shifting component can move the suction head 630 to the position of the lens module 20.

[0092] Optionally, combined Figures 1-4 See Figures 10-13The third vision component 616 includes a third camera 6161, a third illumination device 6162, and a height sensor 6163. The third camera 6161 and the third illumination device 6162 are sequentially arranged from top to bottom on the mounting plate 615. The height sensor 6163 is disposed on the third illumination device 6162 and located on a side of the third illumination device 6162 that avoids being directly below the third camera 6161. The height sensor 6163 is used to sense the distance to the distance module bracket plate 60.

[0093] In this way, the third lighting device 6162 can provide illumination to the lens module 20, so that the third camera 6161 can acquire an image of the lens module 20 exposed through the third lighting device 6162, and locate the position of the lens module 20 on the module bracket plate 60. By using the height sensor 6163 to sense the distance from the module bracket plate 60 to control the lifting of the first lifting device 614, the suction head 630 can be prevented from directly colliding with the module bracket plate 60, thereby protecting the suction head 630.

[0094] Optionally, combined Figures 1-4 See Figures 10-12 The second vision component 700 includes a third support 710, a second lighting device 720, and a second camera 730. The third support 710 is mounted on the frame 100, and the second lighting device 720 and the second camera 730 are sequentially mounted on the third support 710 from bottom to top.

[0095] In the manner described above, when the lens module 20 held by the suction head 630 is moved to the second vision component 700 by the shifting device 610, the second illumination device 720 can provide illumination to the lens module 20 so that the second camera 730 can acquire the image of the lens module 20 exposed through the second illumination device 720 to identify the position of the conductive pins 22 of the lens module 20.

[0096] Optionally, see Figure 10 The second vision component 700 includes a support plate 740 and a light-transmitting dustproof sheet 750. The support plate 740 is disposed on the third bracket 710 and covers the second lighting device 720. The support plate 740 is provided with a light-transmitting opening 741 corresponding to the second lighting device 720. The light-transmitting dustproof sheet 750 is detachably supported in the light-transmitting opening 741.

[0097] In this way, the light-transmitting dustproof sheet 750 can block dust and prevent or reduce dust from falling onto the lens of the second camera 730.

[0098] Optionally, see Figure 10 The second lighting device 720, the second camera 730, the support plate 740 and the light-transmitting dustproof sheet 750 arranged from bottom to top constitute the second structural group 40, and multiple groups of the second structural group 40 are arranged side by side along the longitudinal direction Y.

[0099] Optionally, combined Figures 1-3 See Figures 4-8 The first support 210 suspends the tilting frame 230, forming an overhead space 211 below the tilting frame 230. One end of the tilting drive device 220 is connected to both the tilting frame 230 and the first support 210, and the other end of the tilting drive device 220 extends toward the side where the first vision component 400 is located. When the lens module 20 switches to the material changing posture, the telescopic device 310 is located on the side of the tilting frame 230 closer to the first vision component 400. When the lens module 20 switches to the detection posture, the telescopic device 310 is located in the overhead space 211.

[0100] The above method has at least two beneficial effects. First, because the telescopic device 310 is located on the side of the flip frame 230 closer to the first vision component 400 when the lens module 20 switches to the material changing posture, the telescopic device 310 is less likely to interfere with the movement of the suction head 630 when the shifting device 610 moves the suction head 630 through the second region S2 and out of the first region S1. Second, because the telescopic device 310 is located in the overhead space 211 when the lens module 20 switches to the detection posture, the overall volume of the assembly structure of the flip device 200 and the holding device 300 can be reduced.

[0101] Optionally, combined Figures 1-4 See Figures 10-16 The loading / unloading device 500 includes a first spring-loaded device 510, a second spring-loaded device 520, a picking device 530, and a third lateral shifting device 540. The first spring-loaded device 510 and the second spring-loaded device 520 are used to stack and place the module bracket plate 60. One end of the third lateral shifting device 540 extends below the first spring-loaded device 510 and the second spring-loaded device 520, and the other end extends below the transfer device 600. The picking device 530 is disposed on the slider of the lateral shifting device 610.

[0102] The material handling device 530 is used to take the module bracket plate 60 containing multiple lens modules 20 to be tested from the first clip-type device 510 and to send the module bracket plate 60 containing the tested lens modules 20 to the second clip-type device 520.

[0103] In this manner, when the third lateral shifting device 540 moves the picking device 530 to below the first clip-type device 510, the picking device 530 can cooperate with the first clip-type device 510 to receive the single-layer module bracket plate 60 from the first clip-type device 510. Then, when the third lateral shifting device 540 moves the picking device 530 to the transfer device 600, it facilitates providing the suction head 630 with the lens module 20 to be tested and receiving the tested lens module 20.

[0104] Optionally, combined Figures 1-4 See Figures 10-16 The module bracket plate 60 is provided with multiple module positioning structures 62, which are used to insert and cooperate with the lens module 20 to fix the lens module 20.

[0105] Optionally, combined Figures 1-4 See Figures 10-16 The loading and unloading device 500 may have multiple sets arranged side by side along the longitudinal direction Y. For example, and not as a limitation, the loading and unloading device 500 may have three sets arranged side by side along the longitudinal direction Y.

[0106] Both the first clip-on device 510 and the second clip-on device 520 include a stacking frame 51 and multiple sets of stop devices 52. The stacking frame is mounted on the frame 100 and has a stacking space 51-1 and a transfer space 51-2 continuously arranged from top to bottom. The stacking space 51-1 is used to stack and place module bracket plates 60. Multiple sets of stop devices 52 are arranged around the connection between the stacking space 51-1 and the transfer space 51-2. Each stop device 52 includes a first cylinder 52-1 and a support plate 52-2. The first cylinder 52-1 is mounted on the stacking frame 51, and the support plate 52-2 is mounted on the first cylinder 52-1. The first cylinder 52-1 is used to drive the support plate 52-2, so that the support plate 52-2 of the multiple sets of stopping devices 52 supports or releases the lowest module bracket plate 60 in the stacking space 51-1, thereby preventing or allowing the module bracket plate 60 to move between the stacking space 51-1 and the transfer space 51-2. It should be noted that the periphery of the module bracket plate 60 may be provided with a lifting mating groove 61, and the support plate 52-2 is inserted into the lifting mating groove 61 to support the module bracket plate 60.

[0107] The third lateral shifting device 540 extends to one end below the first clip-on device 510 and the second clip-on device 520, corresponding to the transfer space 51-2. The material handling device 530 includes a second lifting device 531 and a material handling bracket 532. The second lifting device 531 is disposed on the third lateral shifting device 540, and the material handling bracket 532 is disposed on the second lifting device 531. The second lifting device 531 is used to drive the material handling bracket 532 to rise and fall, performing a first engagement or a second engagement. The first engagement includes engaging with the first clip-on device 510 to receive a module bracket plate 60 containing the lens module 20 to be tested from the first clip-on device 510. The second engagement includes engaging with the second clip-on device 520 to deliver the module bracket plate 60 containing the tested lens module 20 to the second clip-on device 520.

[0108] Optionally, the first coordination can be performed sequentially in three steps: a first step, a second step, and a third step. The first step includes multiple sets of stop devices 52 releasing the bottommost module bracket plate 60 within the stacking space 51-1, and a second lifting device 531 raising the material-retrieving bracket 532 to receive the bottommost module bracket plate 60 within the stacking space 51-1. The second step includes the second lifting device 531 lowering the material-retrieving bracket 532, causing the previously bottommost module bracket plate 60 within the stacking space 51-1 to enter the transfer space 51-2, and the previously next-lowermost module bracket plate 60 within the stacking space 51-1 shifting down one layer to become the bottommost module bracket plate 60 within the stacking space. The third step includes multiple sets of stop devices 52 supporting the bottommost module bracket plate 60 within the stacking space 51-1.

[0109] Optionally, the second coordination can be a fourth, fifth, and sixth step executed sequentially. The fourth step includes multiple sets of stop devices 52 releasing the lowest module bracket plate 60 within the stacking space 51-1. The fifth step includes a second lifting device 531 driving the material-retrieving bracket 532 upwards so that the module bracket plate 60 supported on the material-retrieving bracket 532 within the transfer space 51-2 rises into the stacking space 51-1, and the original lowest module bracket plate 60 within the stacking space 51-1 moves one layer up to become the next lowest module bracket plate 60 within the stacking space. The sixth step includes multiple sets of stop devices 52 clamping the lowest module bracket plate 60 within the stacking space 51-1.

[0110] Optionally, combined Figures 1-4 See Figures 10-16 The power-on testing machine 10 includes a control system 800, which is set on the frame 100 and is communicatively connected to the loading / unloading device 500, the transfer device 600, the flipping device 200, the pressing device 300, the first vision component 400, and the second vision component 700 to control the loading / unloading device 500, the transfer device 600, the flipping device 200, the pressing device 300, the first vision component 400, and the second vision component 700 to realize the power-on detection of the lens module 20.

[0111] Optionally, the control system 800 includes a keyboard assembly 1000, a take-up and release assembly 1100, and a controller (not shown). The keyboard assembly 1000 is communicatively connected to the controller, which is communicatively connected to the loading / unloading device 500, the transfer device 600, the flipping device 200, the pressing device 300, the first vision assembly 400, and the second vision assembly 700, respectively, to control the loading / unloading device 500, the transfer device 600, the flipping device 200, the pressing device 300, the first vision assembly 400, and the second vision assembly 700.

[0112] Optionally, combined Figure 1 See Figures 17-19The take-up and take-down assembly 1100 includes a lifting guide rail 1110, a lifting block 1120, a pull rod 1130, and an assembly placement plate 1140. A storage slot 101 is provided on the side wall of the frame 100, and the lifting guide rail 1120 is disposed in the storage slot 101. The lifting block 1120 is slidably disposed on the lifting guide rail 1110. The assembly placement plate 1140 has a first end 1141 near the storage slot 101 and a second end 1142 away from the storage slot 101. The first end 1141 is hinged to the lifting block 1120 to form a first hinge point 1143, and the second end 1142 extends out of the storage slot 101. The pull rod 1130 is located above the assembly placement plate 1140, and one end of the pull rod 1130 is pivotally connected to the frame 100, while the other end of the pull rod 1130 is hinged to the assembly placement plate 1140 to form a second hinge point 1144, thereby holding the assembly placement plate 1140. The second hinge point 1144 is located on the side of the first hinge point 1143 near the second end 1142 and is spaced apart from the second end 1142.

[0113] When the second end 1142 of the component placement plate 1140 is pushed upward, the lever 1130 swings downward, the lifting block 1120 slides downward, and the end of the component placement plate 1140 away from the storage slot 101 swings upward relative to the lifting block 1120, so that the keyboard component 1000 is stored in the storage slot 101 and the component placement plate 1140 covers the storage slot 101.

[0114] The above method offers at least three beneficial effects. First, when the other end of the component placement plate 1140 extends beyond the storage slot 101 to support the keyboard component 1000, it facilitates the operation of the keyboard component 1000 by staff. Second, when the keyboard component 1000 is not in use, it can be stored in the storage slot 101, thus freeing up more space. Third, when the keyboard component 1000 is stored in the storage slot 101, the component placement plate 1140 covers the storage slot 101, thus achieving concealed storage of the keyboard component 1000 within the storage slot 101.

[0115] Optionally, combined Figure 1 See Figures 17-19 The keyboard assembly 1000 includes a keyboard 1010 and a mouse 1020, which are communicatively connected to a controller. A first baffle 1150 and a second baffle 1160 are provided at one end of the assembly placement plate 1140 near the storage slot 101. The first baffle 1150 has a keyboard positioning slot 1151, and the second baffle has a mouse positioning slot 1161.

[0116] In the above manner, when the component placement plate 1140 covers the storage slot 101, the keyboard 1010 can be stored and supported in the keyboard positioning slot 1151, and the indicator can be stored and supported in the mouse positioning slot 1161.

[0117] Optionally, combined Figure 1 See Figures 17-19 A handle portion 1170 protrudes from the lower side of the component placement plate 1140. Thus, when the component placement plate 1140 covers the storage slot 101, pulling the handle portion 1170 outward will cause the pull rod 1130 to swing upward, and the lifting block 1120 to slide upward, and the second end 1142 of the component placement plate 1140 to swing downward relative to the lifting block 1120, so that the keyboard assembly 1000 and the component placement plate 1140 are released from the storage slot 101, and the released component placement plate 1140 supports the keyboard assembly 1000.

[0118] It should be noted that after the component placement plate 1140 is released from the storage slot 101, the center of gravity of the component placement plate 1140 is located on the side of the second hinge point 1144 near the second end 1142. This is so that after the component placement plate 1140 is released from the storage slot 101, the gravity of the component placement plate 1140, the pulling force of the pull rod 1130 on the component placement plate 1140, and the downward pressure of the frame 100 on the lifting block 1120 can be balanced, so that the component placement plate 1140 can stably support the keyboard component 1000.

[0119] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
