[0025] Such as Figure 1As shown in the figure, an optical center testing device for a camera module includes: a panel 1, a bottom plate 2, an adjusting plate 3, and a light source box 4; a storage groove 11 is provided in the center of one side of the panel 1, and four support columns 13 are provided at the bottom of the panel 1. The bottoms of the support columns 13 are connected to the bottom plate 2; guide rails 12 are provided on both sides of the panel 1, and the guide rails 12 are slidably connected to the adjusting plate 3. A light source box 4 is provided at the top of the adjusting plate 3. A chute is provided in the center of the plate body on the side of the adjusting plate 3 close to the light source box 4. A fixed sliding block is provided in the chute, and the sliding block is connected to both ends of the light source box 4; a card slot 41 is provided in the center of the light source box 4. It should be noted that an irradiation light source is placed in the light source box 4, and the test box is placed in the storage groove 11, and the test box is connected to the test module through a test rack. The test module aligns with the test light source to take pictures to obtain optical center data. When a large-angle test is required, only the adjusting plate 3 needs to be moved to drive the light source box 4 to move back and forth, and at the same time, the light source box 4 can be pulled to move up and down, so as to achieve the purpose of adjusting the position of the light source, which can make the optical center test more accurate.

[0026] As Figure 1 shown in an embodiment, the shape of the top view of the panel 1 is rectangular, and both side plates at one end of the panel 1 away from the storage groove 11 extend downward to a certain extent, and the two guide rails 12 are provided on the plate body at this place. There are two adjusting plates 3, which are respectively slidably connected to the guide rails 12, and the light source box 4 is provided on the side where the tops of the two adjusting plates 3 are close to each other. It should be noted that the adjusting plate 3 can be moved back and forth on the guide rail 12 as needed, so as to achieve the purpose of adjusting the position of the light source box 4.

[0027] As Figure 1 shown in an embodiment, the shape of the top view of the storage groove 11 fits the shape of the top view of the test box, and a storage step 14 is provided at the bottom of the storage groove 11. The shape of the top view of the storage step 14 is rectangular, and its length and width are the same as the length and width of the top view of the storage groove 11. It should be noted that this design can prevent the test box placed in the storage groove 11 for testing from falling.

[0028] As Figure 1 shown in an embodiment, the shape of the top view of the light source box 4 is rectangular, and the width of the top view of the light source box 4 fits the width of the top view of the panel 1. It should be noted that the light source box 4 is perpendicular to the panel 1, and the size of the card slot 41 in the light source box 4 is almost the same as the size of the front of the light source box 4. Therefore, the light source placed in the light source box 4 can be a large light source panel or a small light source panel, so as to achieve a wide-angle test.

[0029] As Figure 1As shown in the figure, in one embodiment, four support columns 13 are respectively arranged on the left and right sides of the center of the two ends at the bottom of the panel 1. The bottoms of the four support columns 13 are respectively connected to the four corners of the top of the bottom plate 2. The front surface of the bottom plate 2 is rectangular, and the length of its top view is the same as the length of the top view of the panel 1. It should be noted that the center of the bottom plate 2 is perpendicular and parallel to the center of the panel 1.

[0030] As Figure 1 shown in the figure, in one embodiment, a support step 42 is provided at the bottom of the slot body of the card slot 41. The shape of the top view of the support step 42 is rectangular, and its length and width match the length and width of the top view of the card slot 41. It should be noted that this design can prevent the lighting equipment placed in the light source box 4 from falling out.

[0031] As Figure 1 shown in the figure, in one embodiment, the length of the top view of the storage slot 11 is 2 / 3 of the length of the top view of the panel 1, and the length of the front surface of the guide rail 12 is 1 / 2 of the length of the front surface of the panel 1. It should be noted that this design enables the adjustment plate 3 to move on the guide rail 12, so that the position where the light source irradiates on the storage slot 11 can be adjusted, making the test method more flexible.

[0032] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
