Detailed Embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0029] Reference Figures 1 to 5 In the camera motherboard test system according to the embodiment of the present utility model, it may include a bottom plate 10, a lens fixing seat 20, a first carrier plate 30, a second carrier plate 40, a test board card 50, a plurality of test probes 60, a driving device 70, and a test driving board 80. Among them, the above-mentioned lens fixing seat 20, first carrier plate 30, second carrier plate 40, test board card 50, driving device 70, and test driving board 80 are all arranged on the bottom plate 10.

[0030] The lens fixing seat 20, the first carrier plate 30, and the second carrier plate 40 are arranged at intervals in sequence along the first direction. In practical applications, the first direction here can also be understood as the z direction, and the lens fixing seat 20 is directly placed on the bottom plate 10. In this embodiment, the lens fixing seat 20 is used to place the lens 1, the first carrier plate 30 is used to place the camera motherboard 2, a plurality of test probes 60 are installed on the second carrier plate 40, and the test probes 60 extend along the first direction. The first carrier plate 30 can move relative to the bottom plate 10 along the first direction so that the camera motherboard 2 can be connected to the lens 1. The second carrier plate 40 can move relative to the bottom plate 10 along the first direction so that the first ends of the plurality of test probes 60 are in contact connection with the camera motherboard 2. The test board card 50 is directly opposite to the lens fixing seat 20. When the lens 1 is placed on the lens fixing seat 20, the lens 1 can capture an image of the test board card 50.

[0031] The second ends of the test probes 60 can be used to connect to the test driving board 80. When the test probes 60, the camera motherboard 2, and the lens 1 are connected in sequence, the driving test board card 50 can power on the lens 1, so that the lens 1 is turned on. The test driving board 80 can also be connected to a test device. The test device can be, for example, a computer. The test device is preset with test software. The test software can send test instructions to the driving test board card 50, and the driving test board card 50 can also send signals to the camera motherboard 2. The camera motherboard 2 controls the lens 1 to capture an image of the test board card 50.

[0032] In some embodiments, reference Figure 2 or Figure 3 on, a positioning groove 21 is provided on one side of the lens fixing seat 20 facing the test board card 50. The shape of the positioning groove 21 is adapted to the outer contour of the lens 1. When the lens 1 is placed in the positioning groove 21, the positioning groove 21 can be in contact with the surface of the lens 1, so as to play a role in accurately positioning the lens 1. When the camera motherboard 2 moves along the first direction subsequently, the camera motherboard 2 can be quickly positioned with the lens 1, so as to ensure the accurate connection between the camera motherboard 2 and the lens 1.

[0033] Continue to refer to Figure 2 and Figure 3, the first carrier plate 30 is provided with a limiting groove 31. At least a part of the camera main board 2 is located in the limiting groove 31 and is clamped with the limiting groove 31. Under the limiting action of the limiting groove 31, the relative fixation between the camera main board 2 and the first carrier plate 30 can be maintained. A through hole for passing through the component connecting the camera main board 2 and the lens 1 may be provided at the bottom of the limiting groove 31, so that the component of the camera main board 2 for connecting with the lens 1 can pass through the through hole and then be connected with the lens 1. One side of the camera main board 2 facing the second carrier plate 40 may also expose the surface of the first carrier plate 30, so as to facilitate the contact connection between the camera main board 2 and a plurality of test probes 60 mounted on the second carrier plate 40.

[0034] On one side of the lens fixing seat 20 facing the first carrier plate 30, a first guide post 90 is provided. There may be a plurality of first guide posts 90, and the plurality of first guide posts 90 are distributed at each end of the first carrier plate 30. Each first guide post 90 extends along the first direction. One end of the first guide post 90 is fixedly connected to the lens fixing seat 20, and the other end passes through the first carrier plate 30. The first carrier plate 30 can move relative to the lens fixing seat 20 along the first direction. Under the guiding action of the first guide post 90, it can be ensured that the first carrier plate 30 moves along a preset direction, so as to facilitate the precise connection between the camera main board 2 and the lens 1.

[0035] In addition, a first spring 100 is also connected between the first carrier plate 30 and the lens fixing seat 20, and the first spring 100 is sleeved on the first guide post 90. The first end of the first spring 100 is connected to the first carrier plate 30, and the second end is connected to the lens fixing seat 20. Under the supporting action of the first spring 100, a certain distance is maintained between the first carrier plate 30 and the lens fixing seat 20, and at this time, the first spring 100 is compressed and stores a certain elastic force.

[0036] At the end of the first guide post 90 passing through the first carrier plate 30, a first limiting portion 91 is provided, and the diameter of the first limiting portion 91 is larger than the diameter of the first guide post 90. Since the first spring 100 has a certain elastic force, this elastic force can drive the first carrier plate 30 to move away from the lens fixing seat 20. In the initial state, the first carrier plate 30 abuts against the first limiting portion 91. Under the combined action of the first spring 100 and the first limiting portion 91, the relative fixation between the first carrier plate 30 and the lens fixing seat 20 can be maintained.

[0037] Reference Figure 4 and Figure 5, the second carrier plate 40 may be provided with probe holes (not shown in the figure) corresponding to a plurality of test probes 60. Each test probe 60 is inserted into the probe hole and has an interference fit with the probe hole, so that the test probe 60 and the second carrier plate 40 remain relatively fixed. The second carrier plate 40 is also connected to a floating pressure plate 110 on the side facing the first carrier plate 30. The floating pressure plate 110 is provided with a plurality of second guide pillars 120 on the side facing the second carrier plate 40. Each second guide pillar 120 extends along the first direction. One end of the second guide pillar 120 is fixed to the floating pressure plate 110, and the other end is inserted into the second carrier plate 40. The second carrier plate 40 can move in the first direction relative to the second guide pillar 120. Under the guiding action of the second guide pillar 120, the second carrier plate 40 can be ensured to move in the preset direction, thereby facilitating the precise connection between the camera main board 2 and the test probe 60.

[0038] A second spring 130 is further connected between the second carrier plate 40 and the floating pressure plate 110. The second spring 130 is sleeved around the second guide post 120. One end of the second spring 130 is connected to the floating pressure plate 110, and the other end is connected to the second carrier plate 40. Supported by the second spring 130, a certain distance is maintained between the floating pressure plate 110 and the second carrier plate 40. At this time, the second spring 130 is compressed and has a certain amount of elastic force.

[0039] A second stopper 121 is provided at one end of the second guide post 120 that passes through the second carrier plate 40. The diameter of the second stopper 121 is larger than that of the second guide post 120. The second spring 130 exerts a certain elastic force, which drives the second carrier plate 40 away from the floating pressure plate 110. In the initial state, the second carrier plate 40 abuts the second stopper 121. The cooperation of the second spring 130 and the second stopper 121 maintains a relative fixation between the second carrier plate 40 and the floating pressure plate 110.

[0040] The floating pressure plate 110 also has a clearance groove 111 for clearing the camera mainboard 2. This clearance groove 111 extends through the floating pressure plate 110 along a first direction. This clearance groove 111 allows the portion of the floating pressure plate 110 outside of the clearance groove 111 to mate with the first carrier plate 30, thereby enabling the second carrier plate 40 to drive the first carrier plate 30 to move synchronously toward the lens mount 20. The first end of the test probe 60 protrudes from the second carrier plate 40 toward a side surface of the first carrier plate 30, and the first end of the test probe 60 is located within the clearance groove 111. The second end of the test probe 60 probes a side surface of the second carrier plate 40 facing away from the first carrier plate 30, allowing the second end of the test probe 60 to be connected to the test driver board 80 via a wire.

[0041] In this embodiment, in the initial state, the elastic force of the second spring 130 is greater than the elastic force of the first spring 100. Figure 3 andFigure 4 Specifically, when sequentially connecting the lens 1, camera mainboard 2, and test probe 60, the second carrier plate 40 can be driven to move in the first direction toward the lens mount 20. When the floating pressure plate 110 does not contact the first carrier plate 30, the floating pressure plate 110 and the second carrier plate 40 remain relatively fixed. When the floating pressure plate 110 is pressed against the surface of the first carrier plate 30, the second carrier plate 40 continues to move toward the lens mount 20, simultaneously driving the first carrier plate 30 toward the lens mount 20. Because the elastic force of the second spring 130 is greater than the elastic force of the first spring 100, the first carrier plate 30 can be driven toward the lens mount 20 during the synchronous movement of the first carrier plate 30 and the second carrier plate 40, thereby connecting the lens 1 to the camera mainboard 2. At this point, the floating pressure plate 110 no longer moves. The second carrier plate 40 continues to move toward the floating pressure plate 110 , so that the first end of the test probe 60 can protrude from the surface of the avoidance groove 111 and contact and connect with the camera main board 2 , thereby achieving connection between the test probe 60 , the camera main board 2 and the lens 1 .

[0042] After the test is complete, the second carrier plate 40 is driven away from the lens mount 20, causing the test probe 60 to break contact with the camera main board 2 and the floating pressure plate 110 to break contact with the first carrier plate 30. After the first carrier plate 30 loses its pressure, it automatically moves away from the lens mount 20 under the elastic force of the first spring 100, thereby disconnecting the camera main board 2 from the lens 1.

[0043] It is worth noting that in this embodiment, the elastic force of the second spring 130 is greater than the elastic force of the first spring 100 in the initial state. This prevents the test probe 60 from connecting with the camera main board 2 before the camera main board 2 and the lens 1 during movement of the second carrier board 40 toward the lens mount 20, thereby charging the camera main board 2 and preventing defects in the camera main board 2. Furthermore, maintaining a certain distance between the first carrier board 30 and the lens mount 20 facilitates the removal and placement of the lens 1.

[0044] As an optional embodiment, the driving device 70 may include a cylinder and a connecting plate, wherein the cylinder is fixed to the base plate 10 and the connecting plate is connected to the connection of the cylinder. The second carrier plate 40 may be fixedly connected to the connecting plate, and the cylinder is used to drive the connecting plate to move in the first direction, thereby driving the second carrier plate 40 to move in the first direction.

[0045] In addition, if Figure 1 As shown, a barcode reader 140 is also provided on the base plate 10. The barcode reader 140 is positioned opposite the first carrier plate 30 to facilitate reading the barcode on the camera main board 2 placed on the first carrier plate 30. The barcode reader 140 can upload the read barcode to the testing equipment, which then compares the test results with the code on the camera main board 2 to facilitate product traceability.

[0046] On the bottom plate 10, a start key, a pause key, and a reset key can also be provided. The start key can control the driving device 70 to start working. When a fault occurs during the test, the pause key can be pressed to facilitate the operator to troubleshoot the fault. After returning to normal, the reset key can be pressed to continue the test work.

[0047] Based on the camera motherboard test system introduced in this embodiment, when actually testing the camera motherboard 2, the following process can be referred to:

[0048] Step 1: Place the lens 1 in the lens fixing seat 20, and place the camera motherboard 2 on the first carrier plate 30;

[0049] Step 2: Use the barcode reader 140 to scan the barcode on the camera motherboard 2 and transmit it to the test equipment;

[0050] Step 3: The test software instruction drives the air cylinder to drive the first carrier plate 30 to move towards the lens fixing seat 20. First, connect the camera motherboard 2 to the lens 1, and then connect the test probe 60 to the camera motherboard 2;

[0051] Step 4: After the camera motherboard 2 is connected to the test drive board 80 and the test equipment, use the test software for automatic burning and testing;

[0052] Step 5: After the test is completed, the test software instruction drives the air cylinder to move away from the lens fixing seat 20, and take out the camera motherboard 2, thus completing a test.

[0053] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
