DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] refer to Figure 1 and Figure 2 The camera lens dirty spot test mechanism in the embodiment of the utility model includes a test black box 100, a dirty spot test light board 300 and a test fixture 200, wherein the test fixture 200 is used to place the camera main board 10 to be tested, and the dirty spot test light board 300 is used to provide a test image for the camera main board 10 to be tested, so that the camera main board 10 to be tested can complete the shooting of the dirty spot image.

[0027] Specifically, the test black box 100 includes a first side panel 110 and a second side panel 120 that are arranged oppositely, a third side panel 130 and a fourth side panel 140 that are arranged oppositely, and a top panel 150 and a bottom panel 160 that are arranged oppositely, wherein the first side panel 110 and the second side panel 120 are arranged along a first direction, the third side panel 130 and the fourth side panel 140 are arranged along a second direction, and the top panel 150 and the bottom panel 160 are arranged along a third direction. The dirty spot test light board 300 is located in the test black box 100, and the test black box 100 provides a good test environment for the dirty spot test. The dirty spot test light board 300 can be fixed to the first side panel 110. The second side panel 120 is provided with an opening 121, and the test fixture 200 can be arranged at the opening 121, so that the test fixture 200 can be opposite to the dirty spot test light board 300.

[0028] refer to Figure 3 and Figure 4 The test fixture 200 includes a base module 210, a carrier 220 and a fixing module 230. One side of the carrier 220 is used to place the camera mainboard 10 to be tested. For example, the carrier 220 can be set in a groove 221 that is adapted to the shape of the camera mainboard 10 to be tested, and the camera mainboard 10 to be tested can be snapped into the groove 221, so that the camera mainboard 10 to be tested can be relatively fixed with the carrier 220. The carrier 220 can be rotatably connected to the base module 210 relative to the base module 210, so that the side of the carrier 220 with the groove 221 can be perpendicular to the first direction or perpendicular to the third direction. It can be understood that when the side of the carrier 220 with the groove 221 is perpendicular to the first direction, the side of the carrier 220 with the groove 221 is opposite to the dirty spot test light board 300, that is, the camera mainboard 10 to be tested can be opposite to the dirty spot test light board 300. When the side of the carrier 220 with the groove 221 is perpendicular to the third direction, the carrier 220 can be considered to be placed flat on the base module 210 , which makes it convenient for operators to place the camera motherboard 10 to be tested in the groove 221 or take it out from the groove 221 .

[0029] It should be understood that the second side plate 120 is provided with an opening 121, and the test fixture 200 is placed at the opening 121, which can facilitate the operator to take and place the camera mainboard 10 to be tested. The size of the opening 121 can be substantially the same as the overall size of the test fixture 200. When the test fixture 200 is placed at the opening 121, the test environment in the test black box 100 is basically not affected.

[0030] The fixing module 230 is connected to the carrier 220. When the camera mainboard 10 to be tested is placed in the groove 221, the fixing module 230 can be used to fix the camera mainboard 10 to be tested in the groove 221, so that when the camera mainboard 10 to be tested is facing the dirty spot test light board 300, it can be kept fixed in the groove 221. As an embodiment, the fixing module 230 may include a flip cover 231, which is arranged at the periphery of the groove 221. The flip cover 231 can be rotatably connected to the carrier 220 relative to the carrier 220, so that the large surface of the flip cover 231 is parallel to the side of the carrier 220 where the groove 221 is set or perpendicular to the side of the carrier 220 where the groove 221 is set. When the large surface of the flip cover 231 is parallel to the side surface of the carrier 220 where the groove 221 is set, that is, the flip cover 231 is placed flat on the carrier 220, at this time, a part of the flip cover 231 is opposite to the groove 221 to be pressed onto the camera mainboard 10 to be tested, so that the camera mainboard 10 to be tested is fixed in the groove 221.

[0031] like Figure 4 As shown, there can be two flip covers 231, and the two flip covers 231 are respectively arranged on the opposite sides of the groove 221. When the two flip covers 231 are respectively parallel to the sides of the groove 221 set on the carrier plate 220, the two flip covers 231 are respectively pressed on the opposite sides of the camera mainboard 10 to be tested, which can achieve a better fixing effect on the camera mainboard 10 to be tested.

[0032] Each flip cover 231 can be connected to the carrier 220 through a hinge structure. When the flip cover 231 is flipped to the side perpendicular to the carrier 220 where the groove 221 is set, the flip cover 231 can remain relatively fixed with the carrier 220 autonomously, thereby preventing the flip cover 231 from falling when the operator takes and places the camera motherboard 10 to be tested.

[0033] In addition, continue to refer to Figure 4 A handle 232 protruding from the flip cover 231 may also be provided on each flip cover 231. When the operator rotates the flip cover 231, a force can be applied to the handle 232 to change the flip cover 231 from a state of being pressed against the camera main board 10 to a state of being detached from the camera main board 10 to be tested.

[0034] In some embodiments, continue to refer to Figure 4 The base module 210 includes a fixed base 211 and an adjustment base 212, the adjustment base 212 and the fixed base 211 are arranged along the third direction, and the adjustment base 212 is connected to the fixed base 211. In addition, the test fixture 200 also includes a connecting base 240, which is disposed between the adjustment base 212 and the carrier 220, and the carrier 220 can be rotatably connected to the connecting base 240 relative to the connecting base 240.

[0035] refer to Figure 5 , the connection seat 240 can move relative to the adjustment seat 212 along the second direction, so as to adjust the relative position between the connection seat 240 and the adjustment seat 212, thereby facilitating the adjustment of the relative position between the camera main board 10 to be tested and the dirty spot test light board 300 in the second direction. Specifically, the connection seat 240 is provided with a first waist-shaped hole 241 extending along the second direction, and a first threaded hole can be provided on the adjustment seat 212. When the connection seat 240 is connected to the adjustment seat 212, the first locking screw provided through the first waist-shaped hole 241 can be connected to the first threaded hole, thereby realizing the connection between the connection seat 240 and the adjustment seat 212.

[0036] When the relative position between the connecting seat 240 and the adjusting seat 212 needs to be adjusted, the connecting seat 240 can be moved to a suitable position along the second direction, and then the connecting seat 240 and the adjusting seat 212 are connected by the first locking screw. That is, in this embodiment, the relative position between the connecting seat 240 and the adjusting seat 212 is achieved by adjusting the locking position of the first locking screw in the first waist-shaped hole 241.

[0037] Further, continue to refer to Figure 4 , the adjustment seat 212 can also move relative to the fixed base 211 along the third direction, so as to adjust the relative position between the adjustment seat 212 and the fixed base 211, thereby facilitating the relative position between the camera mainboard 10 to be tested and the dirty spot test light board 300 in the third direction. As an implementation scheme, the adjustment seat 212 is provided with second waist-shaped holes 2121 on two opposite sides along the second direction, and the second waist-shaped holes 2121 extend along the third direction, and second threaded holes are provided on both sides of the fixed base 211. When the adjustment seat 212 and the fixed base 211 are connected, they can be connected to the second threaded hole by a second locking screw penetrating the second waist-shaped hole 2121, thereby realizing the connection between the adjustment seat 212 and the fixed base 211.

[0038] When the relative position between the fixed base 211 and the adjustable base 212 needs to be adjusted, the adjustable base 212 can be moved to a suitable position along the third direction, and then the second locking screw is used to connect the fixed base 211 and the adjustable base 212. That is, in this embodiment, the relative position between the fixed base 211 and the adjustable base 212 is achieved by adjusting the locking position of the second locking screw in the second waist-shaped hole 2121.

[0039] Further, refer to Figure 5The fixed base 211 can also move relative to the bottom plate 160 in the first direction, so as to adjust the relative position between the fixed base 211 and the bottom plate 160, thereby facilitating the relative position between the camera mainboard 10 to be tested and the dirty spot test light board 300 in the first direction. As an implementation scheme, the fixed base 211 is provided with a third waist-shaped hole 2111, and the third waist-shaped hole 2111 extends along the first direction, and the bottom plate 160 is provided with a third threaded hole. When the fixed base 211 and the bottom plate 160 are connected, they can be connected by a third locking screw penetrating the third waist-shaped hole 2111 and the third threaded hole, thereby realizing the connection between the fixed base 211 and the bottom plate 160.

[0040] When the relative position between the fixed base 211 and the bottom plate 160 needs to be adjusted, the fixed base 211 can be moved to a suitable position along the first direction, and then the third locking screw is used to connect the fixed base 211 and the bottom plate 160. That is, in this embodiment, the relative position between the fixed base 211 and the bottom plate 160 is achieved by adjusting the locking position of the third locking screw in the third waist-shaped hole 2111.

[0041] Referring to the figure, the first side panel 110 is provided with a plurality of latching structures 400. When the dirty spot test light board 300 is fixed to the first side panel 110, the plurality of latching structures 400 cooperate to latch the dirty spot test light board 300, thereby ensuring that the dirty spot test light board 300 can remain fixed during the test process.

[0042] The camera lens dirt spot testing mechanism in this embodiment may also include a testing computer, on which corresponding testing software is provided, so that the image captured by the camera mainboard 10 to be tested can be processed by the testing software to determine the dirt spot test result.

[0043] Based on the specific structure of the camera lens dirty spot testing mechanism in this embodiment, when performing a dirty spot test on the camera mainboard 10 to be tested, the following steps may be referred to.

[0044] Step 1: Open the test software, place the camera mainboard 10 to be tested into the test fixture 200, and flash the QR code on the camera to be tested into the test software;

[0045] Step 2: The camera mainboard 10 to be tested is turned on and connected to the test computer via a USB cable;

[0046] Step 3: Flip the carrier board 220 so that the camera main board 10 to be tested is facing the dirty spot test light board 300;

[0047] Step 4: Click the test software to start the dirty spot test. The test software controls the camera mainboard 10 to be tested to perform the dirty spot test, and after judging OK / NG, uploads the test result to the system;

[0048] Step 5: Turn off the camera mainboard 10 to be tested, unplug the USB cable, and remove the camera mainboard 10 to be tested that has completed the test.
