Description

Technical Field

[0001] This invention relates to the field of camera aging test technology, and in particular to an aging fixture and aging equipment for camera modules. Background Technology

[0002] During the camera manufacturing process, camera modules need to undergo aging tests to detect early failures by simulating prolonged use. During these tests, the camera module needs to be powered on for extended periods. Typically, conductive contacts, such as pins, are used to connect to the circuit board of the camera module under test for power supply or signal transmission.

[0003] In existing technologies, manual operation is required. Operators need to physically connect the camera module to the testing device, manually adjust the contact position of the pins and the test points on the circuit board, and then manually fasten the product shell to trigger the temporary circuit to establish the power supply and signal transmission channels. Before and after aging tests, the testing device needs to be manually moved to different workstations and the disassembly and assembly process needs to be repeated. The entire process relies on manual operation, resulting in low material loading efficiency that cannot meet the needs of large-scale production. At the same time, during the manual connection process, operators need to frequently come into contact with the powered equipment, which poses a risk of high temperature burns and electrostatic damage. Furthermore, manual operation is prone to problems such as poor contact and positioning misalignment, which affects the reliability of the test results. Summary of the Invention

[0004] To address the shortcomings of the prior art, the present invention provides an aging fixture and aging equipment for camera modules, which avoids the problems of poor contact and positioning misalignment between the camera module under test and the testing components, as well as low efficiency of aging tests, when using manual operation.

[0005] The technical effects to be achieved by this invention are realized through the following aspects: In a first aspect, the present invention provides an aging fixture for a camera module, comprising: The testing mechanism includes a testing component and a first driving component, wherein the first driving component drives the testing component to move closer to or away from the testing station located above the testing mechanism in a vertical direction; A feeding mechanism, located above the testing mechanism, is used to horizontally feed the camera module to be tested into or out of the testing station; and The pressing mechanism is located above the feeding mechanism and is vertically close to or away from the detection station; When the feeding mechanism, the detection component, and the pressing mechanism all move to the detection station, the pressing mechanism fixes the camera module under test in the feeding mechanism, and the detection component moves close to the feeding mechanism to detect the camera module under test.

[0006] In some implementations, the feeding mechanism has a placement window for placing a tray, the tray being used to place the camera module under test, and the detection component passing through the placement window to detect the camera module under test.

[0007] In this implementation, the placement window is connected to the testing station. The testing component passes through the placement window into the testing station and comes into contact with the camera module under test, thereby physically connecting with the camera module under test and achieving circuit conduction, thus ensuring the reliability of the camera module aging test.

[0008] In some implementations, a first positioning mechanism is provided between the feeding mechanism and the tray, and the tray is fixed to the feeding mechanism by the first positioning mechanism.

[0009] In this implementation, the first positioning mechanism ensures accurate alignment and connection between the tray and the feeding mechanism, thereby guaranteeing the stability of the camera module under test.

[0010] In some implementations, the first positioning mechanism includes a positioning pin, which is disposed on the feeding mechanism, and the material tray has a positioning hole that fits onto the positioning pin.

[0011] In some implementations, the feeding mechanism includes a slider, a slide rail, a feeding plate, and a second driving member. The slider is connected to the detection mechanism, the slide rail is slidably connected to the slider, the feeding plate is connected to the slide rail, the second driving member is driven to connect to the feeding plate, and the placement window is opened on the feeding plate.

[0012] In some implementations, the detection component includes a fixed plate and an ejector pin module, the ejector pin module being connected to the fixed plate and facing the detection station, and the first driving member being driven connected to the side of the fixed plate opposite to the ejector pin module.

[0013] In some implementations, a second positioning mechanism is provided between the detection mechanism and the feeding mechanism, and the detection component performs positioning detection on the camera module under test through the second positioning mechanism when it approaches the feeding mechanism.

[0014] In this implementation, the second positioning mechanism ensures precise alignment of the test points of the ejector module and the camera module under test, thereby guaranteeing the accuracy of the connection between the ejector module and the camera under test, and thus ensuring the reliability of the camera module aging test.

[0015] In some implementations, the second positioning mechanism includes a positioning guide post and a positioning guide sleeve. The positioning guide post is disposed on the side of the detection component near the feeding mechanism, and the positioning guide sleeve is disposed on the feeding mechanism. When the detection component is near the feeding mechanism, the positioning guide post passes through the positioning guide sleeve.

[0016] In some implementations, the pressing mechanism includes a pressing plate, a fixing block, and a third driving member. The fixing block is connected to the pressing plate and forms an installation space between the fixing block and the pressing plate. The installation space is used to place a positioning plate for fixing the camera module under test. The third driving member is driven to the side of the pressing plate opposite to the feeding mechanism.

[0017] In this implementation, the pressure plate moves closer to the testing station under the drive of the third driving component, so that the positioning plate can fix and position the camera module under test.

[0018] In some implementations, the pressing mechanism further includes a buffer assembly, which includes a buffer post and an elastic element. The buffer post is connected to the side of the pressing plate near the feeding mechanism. The end of the buffer post facing away from the pressing plate has a radially extending protrusion. The elastic element is sleeved on the buffer post and its two ends abut against the pressing plate and the protrusion, respectively.

[0019] In a second aspect, the present invention provides an aging device for a camera module, comprising: An aging furnace, wherein an aging fixture for camera modules as described above is stacked in an array inside the aging furnace; A loading and unloading mechanism is located on the side of the inlet and outlet of the aging furnace to load and unload the aging fixture; and A reflux mechanism is located on the side of the loading and unloading mechanism away from the aging furnace to collect empty material trays after unloading.

[0020] In some implementations, the aging furnace includes multiple independent aging chambers arranged in a vertical array, each aging chamber containing an aging fixture for the camera module.

[0021] In some implementations, there are multiple return mechanisms, and these multiple return mechanisms are continuously arranged along the flow line direction; The return mechanism includes a conveyor belt, a lifting assembly, and a supporting assembly. The lifting assembly is located below the conveyor belt, and the supporting assembly is located above the conveyor belt. The lifting assembly lifts the empty pallet, which is conveyed by the conveyor belt to the top of the lifting assembly, onto the supporting assembly so that the supporting assembly supports the empty pallet.

[0022] In some implementations, the support assembly includes a stacking rack, a support plate, and a support drive. The stacking rack is mounted above the conveyor belt and has a stacking window. The support plate is located around the periphery of the stacking window. The support drive is driven to the support plate. The lifting assembly is located below the stacking window.

[0023] In this implementation, the lifting component lifts the empty material tray. After the empty material tray passes through the stacking window, the support drive component drives the support plate to extend, so that the support plate supports the empty material tray, thereby realizing the stacking of the empty material trays.

[0024] In some implementations, the support assembly further includes a limiting plate connected to the side of the stacking rack opposite the conveyor belt and located at the periphery of the stacking window.

[0025] In some implementations, the return flow mechanism further includes a stop assembly, which includes a stop element and a stop drive element. The stop element is located downstream of the lifting assembly, and the stop drive element is driven to the stop element.

[0026] In some implementations, the loading and unloading mechanism includes a robotic arm, grippers, and a camera assembly. The robotic arm is slidably disposed relative to the aging furnace, the grippers are rotatably connected to the robotic arm, and the camera assembly is connected to the grippers.

[0027] In some implementations, the aging device for the camera module also includes a shooting and positioning mechanism for shooting the camera module under test on the positioning tray.

[0028] In summary, the present invention has at least the following advantages: The aging fixture and aging equipment for camera modules provided by this invention involve a feeding mechanism that horizontally moves the camera module to be tested to the testing station, followed by a pressing mechanism that vertically approaches the testing station to fix the camera module in place. Then, a testing component, driven by a first driving component, approaches the testing station and abuts against the camera module, physically connecting the testing component to the test points of the camera module, thereby achieving circuit continuity and realizing the aging test of the camera module. This avoids the problems of poor contact and positioning misalignment between the camera module and the testing component, as well as the low efficiency of aging tests, that are common with manual operation.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] Example 1: Please see the appendix Figure 1 ~Appendix Figure 3 The aging fixture 10 for the camera module of the present invention includes a detection mechanism 100, a feeding mechanism 200 and a pressing mechanism 300.

[0034] Please see below. Figure 1 , Figure 1 The diagram illustrates the structural relationship between the detection mechanism 100, the feeding mechanism 200, and the pressing mechanism 300 in an embodiment of the present invention. Specifically, the detection mechanism 100 includes a detection component 110 and a first driving member 120. The first driving member 120 drives the detection component 110 to move vertically closer to or away from the detection station 101 located above the detection mechanism 100. The feeding mechanism 200 is located above the detection mechanism 100 and is used to feed the camera module under test into or out of the detection station 101 horizontally. The pressing mechanism 300 is located above the feeding mechanism 200 and moves vertically closer to or away from the detection station 101. When the feeding mechanism 200, the detection component 110, and the pressing mechanism 300 all move to the detection station 101, the pressing mechanism 300 fixes the camera module under test in the feeding mechanism 200, and the detection component 110 moves closer to the feeding mechanism 200 to detect the camera module under test.

[0035] In this embodiment, the first driving component 120 drives the detection component 110 to move closer to or further away from the detection station 101 in the vertical direction, the feeding mechanism 200 feeds the camera module to be tested into or out of the detection station 101 in the horizontal direction, and the pressing mechanism 300 moves closer to or further away from the detection station 101 in the vertical direction. When the feeding mechanism 200, the detection component 110 and the pressing mechanism 300 all move to the detection station 101, the aging test of the camera module to be tested is realized.

[0036] Specifically, after the feeding mechanism 200 moves the camera module under test to the testing station 101 horizontally, the pressing mechanism 300 approaches the testing station 101 vertically, fixing the camera module under test in the testing station 101 to ensure its stability. The first driving component 120 drives the detection component 110 to approach the testing station 101 vertically, causing the detection component 110 to abut against the camera module under test. The detection component 110 physically connects with the test points of the camera module under test, thereby achieving circuit continuity and realizing the aging test of the camera module. After the aging test is completed, the detection component 110 and the pressing mechanism 300 move away from the testing station 101 vertically in sequence, and the feeding mechanism 200 sends the camera module out of the testing station 101 horizontally for subsequent unloading.

[0037] The aforementioned camera module aging fixture 10 involves a feeding mechanism 200 horizontally transporting the camera module under test to the testing station 101. A pressing mechanism 300 then vertically approaches the testing station 101 to fix the camera module in place. Subsequently, the testing component 110, driven by the first driving component 120, approaches the testing station 101 and abuts against the camera module under test. The testing component 110 physically connects with the test points of the camera module under test, thereby achieving circuit continuity and realizing the aging test of the camera module. This avoids the problems of poor contact and positioning misalignment between the camera module under test and the testing component 110, as well as the low efficiency of aging tests, that are common with manual operation.

[0038] In some preferred embodiments, please refer to Figure 2 and Figure 3 , Figure 2 and Figure 3The diagram illustrates the structural relationship between the feeding mechanism 200 and the tray 400 in this embodiment of the invention. Specifically, the feeding mechanism 200 has a placement window 201 for placing the tray 400. The tray 400 is used to place the camera module under test. The detection component 110 passes through the placement window 201 to detect the camera module under test. The placement window 201 is connected to the detection station 101. The detection component 110 passes through the placement window 201, enters the detection station 101, and abuts against the camera module under test, thereby establishing a physical connection with the camera module and achieving circuit continuity, ensuring the reliability of the camera module aging test.

[0039] Example 2: The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the aging fixture 10 for the camera module of the present invention. Please refer to the appendix. Figure 2 ~Appendix Figure 5 .

[0040] Please see below. Figure 2 , Figure 2 The diagram illustrates the structural relationship between the first positioning mechanism 500 and the feeding mechanism 200 in an embodiment of the present invention. Specifically, the first positioning mechanism 500 is provided between the feeding mechanism 200 and the material tray 400, and the material tray 400 is fixed to the feeding mechanism 200 by the first positioning mechanism 500.

[0041] In this embodiment, the first positioning mechanism 500 ensures accurate alignment and connection between the material tray 400 and the feeding mechanism 200, thereby guaranteeing the stability of the camera module under test.

[0042] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the positioning pin 510 and the positioning hole 401 in an embodiment of the present invention. Specifically, the first positioning mechanism 500 includes a positioning pin 510, which is disposed on the feeding mechanism 200. The tray 400 has a positioning hole 401 that fits onto the positioning pin 510. When the tray 400 is placed on the feeding mechanism 200, the positioning hole 401 on the tray 400 fits onto the positioning pin 510 on the feeding mechanism 200, thereby fixing the tray 400 on the feeding mechanism 200. This avoids the problem of the tray 400 moving when the detection component 110 performs aging tests on the camera module under test, which would cause a misalignment between the detection component 110 and the camera module under test.

[0043] In some preferred embodiments, please refer to Figure 2 , Figure 2The diagram illustrates the structural relationship between the slider 210 and the slide rail 220 in an embodiment of the present invention. Specifically, the feeding mechanism 200 includes a slider 210, a slide rail 220, a feeding plate 230, and a second driving member 240. The slider 210 is connected to the detection mechanism 100, the slide rail 220 is slidably connected to the slider 210, the feeding plate 230 is connected to the slide rail 220, and the second driving member 240 is drivenly connected to the feeding plate 230. A placement window 201 is opened on the feeding plate 230. The feeding plate 230 moves horizontally towards or away from the detection station 101 via the driving member of the second driving member 240. The slide rail 220 is slidably connected to the slider 210, allowing the feeding plate 230 to slide relative to the detection mechanism 100, thus ensuring the sliding stability of the feeding plate 230.

[0044] In some preferred embodiments, please refer to Figure 4 , Figure 4 The diagram illustrates the structural relationship between the fixing plate 111 and the ejector module 112 in this embodiment of the invention. Specifically, the detection assembly 110 includes a fixing plate 111 and an ejector module 112. The ejector module 112 is connected to the fixing plate 111 and is positioned facing the detection station 101. A first driving member 120 drives the side of the fixing plate 111 facing away from the ejector module 112. The first driving member 120 drives the fixing plate 111 to move, thereby causing the ejector module 112 to move closer to or away from the detection station 101. When the ejector module 112 moves closer to the detection station 101, the ejector module 112 physically connects with the test point of the camera module under test, thereby making the circuit conductive and realizing the aging test of the camera module.

[0045] Preferably, the ejector module 112 includes a plurality of ejector pins arranged in an array, and a plurality of camera modules to be tested are placed on the tray 400 arranged in an array. The plurality of ejector pins are connected to the plurality of camera modules to be tested one by one, thereby realizing the aging test of the plurality of camera modules to be tested, thus improving the aging test efficiency of the camera modules.

[0046] In some preferred embodiments, please continue to refer to Figure 4 , Figure 4 The diagram illustrates the structural relationship between the detection mechanism 100 and the second positioning mechanism 600 in this embodiment of the invention. Specifically, a second positioning mechanism 600 is provided between the detection mechanism 100 and the feeding mechanism 200. When the detection component 110 approaches the feeding mechanism 200, the second positioning mechanism 600 performs positioning detection on the camera module under test. The second positioning mechanism 600 ensures precise alignment between the ejector pin module 112 and the test point of the camera module under test, thereby guaranteeing the accuracy of the docking between the ejector pin module 112 and the camera under test, and thus ensuring the reliability of the camera module aging test.

[0047] In some preferred embodiments, the second positioning mechanism 600 includes a positioning guide post 610 and a positioning guide sleeve 620. The positioning guide post 610 is disposed on the side of the detection component 110 near the feeding mechanism 200, and the positioning guide sleeve 620 is disposed on the feeding mechanism 200. When the detection component 110 approaches the feeding mechanism 200, the positioning guide post 610 passes through the positioning guide sleeve 620. The detection component 110 and the feeding plate 230 are arranged parallel to each other. When the detection component 110 approaches the detection station 101 in the vertical direction, the positioning guide post 610 passes through the positioning guide sleeve 620 to fix the detection component 110 and the feeding plate 230 to each other, thereby ensuring that the ejector pin module 112 is accurately aligned with the test point of the camera module under test. This avoids the problem of offset or shaking during the aging test.

[0048] In some preferred embodiments, please refer to Figure 5 , Figure 5 The diagram illustrates the structural relationship between the pressure plate 310, the fixing block 320, and the positioning plate 350 in an embodiment of the present invention. Specifically, the pressure mechanism 300 includes a pressure plate 310, a fixing block 320, and a third driving member 330. The fixing block 320 is connected to the pressure plate 310 and forms an installation space 311 between itself and the pressure plate 310. The installation space 311 is used to place and fix the positioning plate 350 of the camera module under test. The third driving member 330 is driven to the side of the pressure plate 310 facing away from the feeding mechanism 200. Driven by the third driving member 330, the pressure plate 310 approaches the testing station 101, thereby fixing and positioning the camera module under test. It is understandable that the positioning plate 350 has a limiting hole 351. When the positioning plate 350 is close to the camera module under test, the limiting hole 351 is fitted onto the camera module under test to achieve positioning. At the same time, the limiting hole 351 also plays a role in avoiding interference between the positioning plate 350 and the lens of the camera module under test when the positioning plate 350 is in contact with the camera module under test.

[0049] The positioning plate 350 is installed in the installation space 311. When aging tests are performed on different models of camera modules, the positioning plate 350 can be replaced according to the different models of camera modules, thereby improving the overall reliability of the fixture.

[0050] Furthermore, a fastener is provided between the lower pressure plate 310 and the positioning plate 350, the fastener being used to fix the positioning plate 350 within the installation space 311. Preferably, the fastener can be an indexing pin.

[0051] In some more preferred embodiments, the pressing mechanism 300 further includes a buffer assembly 340, which includes a buffer post 341 and an elastic element 342. The buffer post 341 is connected to the side of the pressing plate 310 near the feeding mechanism 200. A protrusion 3411 extends radially from the end of the buffer post 341 away from the pressing plate 310. The elastic element 342 is sleeved on the buffer post 341, and its two ends abut against the pressing plate 310 and the protrusion 3411, respectively. When the pressing plate 310 approaches the detection station 101, the buffer post 341 abuts against the feeding plate 230. Under the elastic force of the elastic element 342, the limiting hole 351 of the positioning plate 350 is more stably sleeved on the camera module under test.

[0052] Example 3: This embodiment, based on the above embodiments, provides an aging device 20 for a camera module. Please refer to the appendix. Figure 6 ~Appendix Figure 11 .

[0053] An aging device 20 for a camera module includes an aging furnace 700, a loading and unloading mechanism 800, and a recirculation mechanism 900.

[0054] Please see below. Figure 6 , Figure 6 The diagram illustrates the structural relationship between the aging furnace 700, the loading / unloading mechanism 800, and the reflux mechanism 900 in an embodiment of the present invention. Specifically, the aging furnace 700 contains stacked aging fixtures 10 for camera modules as described above; the loading / unloading mechanism 800 is located on the side where the inlet and outlet of the aging furnace 700 are located to load and unload the aging fixtures; the reflux mechanism 900 is located on the side of the loading / unloading mechanism 800 away from the aging furnace 700 to collect empty trays after unloading.

[0055] In this embodiment, the loading / unloading mechanism 800 picks up the tray 400 containing the camera module to be tested and places it on the feeding mechanism 200 of the aging fixture. After the aging fixture performs aging tests on the camera module to be tested, the loading / unloading mechanism 800 picks up the tray 400 from the feeding mechanism 200 and transfers it to the unloading station for unloading. The empty tray after unloading is placed on the return mechanism 900, and then transported to the loading station for loading through the return mechanism 900. This realizes automatic loading and unloading of camera modules during the aging process, avoiding the problem of low loading efficiency and inability to meet the needs of large-scale production when relying on manual operation throughout the process, and saving labor costs.

[0056] In some preferred embodiments, please refer to Figure 7 , Figure 7The diagram illustrates the structural relationship between the aging chamber 710 and the rotating plate 720 in an embodiment of the present invention. The aging furnace 700 includes multiple independent aging chambers 710 arranged in a vertical array, each aging chamber 710 containing an aging fixture 10 for a camera module. This facilitates control over the aging time of the camera module in each aging fixture 10, enhancing the flexibility of the camera module aging test. The aging furnace also includes multiple rotating plates 720, each rotatably connected to the inlet and outlet of one of the aging chambers 710. These plates cover the inlet and outlet of the aging chambers 710 during aging tests, creating a sealed space and ensuring the reliability of the camera module aging test.

[0057] Specifically, during the aging test, the feeding plate 230 of the aging fixture 10 for the camera module located in the aging chamber 710 extends out of the aging chamber 710 under the drive of the second drive member 240. The loading and unloading mechanism 800 places the tray 400 on the placement window 201 of the feeding plate 230. The second drive member 240 drives the feeding plate 230 to move again so that the feeding plate 230 retracts into the aging chamber 710. The rotating plate 720 rotates to cover the inlet and outlet of the aging chamber 710. The external power source is turned on to perform the aging test on the camera module.

[0058] In some preferred embodiments, please refer to Figure 8 and Figure 9 , Figure 8 and Figure 9 The diagram illustrates the structural relationship between the conveyor belt 910, the lifting assembly 920, and the supporting assembly 930 in an embodiment of the present invention. Specifically, there are multiple return mechanisms 900, which are continuously arranged along the production line direction. Each return mechanism 900 includes a conveyor belt 910, a lifting assembly 920, and a supporting assembly 930. The lifting assembly 920 is located below the conveyor belt 910, and the supporting assembly 930 is located above the conveyor belt 910. The lifting assembly lifts the empty pallet, which has been conveyed by the conveyor belt 910 to the area above the lifting assembly 920, to the supporting assembly 930, so that the supporting assembly 930 supports the empty pallet.

[0059] In this example, during normal return flow, the empty trays to be stacked are conveyed to the area below the lifting component 920 via the conveyor belt 910. After the lifting component 920 lifts the empty trays to be stacked, the supporting component 930 extends to support the empty trays so that they are stacked away from the conveyor belt 910. When the next empty tray to be stacked is conveyed to the area above the lifting component 920 via the conveyor belt 910, the supporting component 930 retracts so that the already stacked empty trays are stacked on top of the empty trays to be stacked, thereby stacking multiple empty trays together. The lifting component 920 lifts the stacked empty trays, and the supporting component 930 extends again to support the stacked empty trays away from the conveyor belt 910, thus achieving the stacking of empty trays.

[0060] When changing models, i.e., when replacing camera modules with different models for aging tests, the model of material tray 400 will also be changed. Since multiple return mechanisms 900 are set up in succession, the empty material tray before changing models can be conveyed by conveyor belt 910 to the last return mechanism 900 for stacking, while the empty material tray after changing models can be stacked on another return mechanism 900. This facilitates subsequent sorting and loading.

[0061] In some preferred embodiments, please refer to Figure 10 , Figure 10 The diagram illustrates the structural relationship between the stacking rack 931 and the support plate 932 in an embodiment of the present invention. Specifically, the support assembly 930 includes a stacking rack 931, a support plate 932, and a support drive component 933. The stacking rack 931 is mounted above the conveyor belt 910 and has a stacking window 9311. The support plate 932 is located around the periphery of the stacking window 9311. The support drive component 933 is driven and connected to the support plate 932. The lifting assembly 920 is located below the stacking window 9311. The lifting assembly 920 lifts the empty tray. After the empty tray passes through the stacking window 9311, the support drive component 933 drives the support plate 932 to extend, so that the support plate 932 supports the empty tray, thereby realizing the stacking of the empty trays.

[0062] In some preferred embodiments, the support assembly 930 further includes a limiting plate 934, which is connected to the side of the stacking rack 931 facing away from the conveyor belt 910 and located at the periphery of the stacking window 9311. The limiting plate 934 ensures stable stacking of empty trays, preventing the stacked empty trays from shaking or shifting.

[0063] In some preferred embodiments, please continue to refer to Figure 10 , Figure 10The diagram illustrates the structural relationship between the stop assembly 940 and the lifting assembly 920 in this embodiment of the invention. Specifically, the return mechanism 900 further includes the stop assembly 940, which comprises a stop element 941 and a stop drive element 942. The stop element 941 is located downstream of the lifting assembly 920, and the stop drive element 942 is drivenly connected to the stop element 941. When an empty tray is conveyed to the top of the lifting assembly 920 via the conveyor belt 910, the stop drive element 942 drives the stop element 941 to extend, thereby stopping the empty tray and facilitating the lifting assembly 920 to lift the empty tray.

[0064] In some preferred embodiments, please refer to Figure 11 , Figure 11 The diagram illustrates the structural relationship between the robotic arm 810, gripper 820, and imaging component 830 in an embodiment of the present invention. Specifically, the loading / unloading mechanism 800 includes a robotic arm 810, gripper 820, and imaging component 830. The robotic arm 810 is slidably disposed relative to the aging furnace 700, the gripper 820 is rotatably connected to the robotic arm 810, and the imaging component 830 is connected to the gripper 820. During loading, the gripper 820 grasps the material tray 400, and the robotic arm 810 moves, thereby driving the gripper 820 to move, thus placing the material tray 400 on the feeding mechanism 200 of the aging fixture. The positioning hole 401 of the material tray 400 is fitted onto the positioning pin 510 of the feeding mechanism 200, and then the imaging component 830 images the positioning pin 510 to ensure correct placement. Furthermore, a groove is formed on the periphery of the material tray 400, and the gripper 820 is held in the groove to ensure gripping stability.

[0065] In some more preferred embodiments, the camera module aging device 20 further includes a shooting and positioning mechanism 1000 for shooting and positioning the camera module under test on the positioning tray 400. During loading, the gripper 820 grabs the tray 400, and the robotic arm 810 moves, thereby moving the gripper 820 to the shooting and positioning mechanism 1000. The shooting and positioning mechanism 1000 shoots and positions the camera module under test on the tray 400. After confirming that there is no problem, the gripper 820 places the tray 400 on the feeding mechanism 200.

[0066] Furthermore, the camera module aging device 20 also includes a barcode scanning mechanism. After the gripper 820 picks up the material tray 400, the barcode scanning mechanism scans and identifies the barcode, which facilitates tracking the aging test process of the camera module under test on the material tray 400.

[0067] The camera module aging device 20 of the present invention includes a feeding mechanism 200 that horizontally moves the camera module under test to the testing station 101, followed by a pressing mechanism 300 that vertically approaches the testing station 101 to fix the camera module under test in the testing station 101. Then, the testing component 110, driven by the first driving component 120, approaches the testing station 101 and abuts against the camera module under test. The testing component 110 physically connects with the test points of the camera module under test, thereby achieving circuit continuity and realizing the aging test of the camera module. This avoids the problems of poor contact and positioning misalignment between the camera module under test and the testing component 110, as well as the low efficiency of aging tests, that are easily caused by manual operation.

[0068] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0069] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0070] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0071] In this invention, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0072] Although the description of the invention has been given in conjunction with the specific embodiments described above, it will be apparent to those skilled in the art that many substitutions, modifications, and variations can be made based on the foregoing. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
