[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of the present invention, it should be understood that the term "comprising" as used in the present specification refers to the presence of the features, integers, steps, operations, parts / components and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, parts / components, components and / or groups thereof. It should be understood that when we say a part / component is "connected" to another part / component, it can be directly connected to the other part / component, or there can be intermediate parts / components. The term "and / or" as used herein includes all or any one of the associated listed items and all combinations.

[0027] like Figures 1 to 4 As shown, the utility model relates to a focus test device for shooting front and rear cameras of a mobile phone, comprising a support frame 1, a mounting platform 2, a rotating drive member 3 and a focus picture 4, wherein the support frame 1 and the focus picture 4 are arranged at intervals, the mounting platform 2 is used to place and fix the mobile phone 100, the mounting platform 2 is connected to the support frame 1, and can rotate relative to the support frame 1, the rotating drive member 3 is installed on the support frame 1, and is connected to the mounting platform 2 to drive the mounting platform 2 to rotate, thereby driving the mobile phone 100 on the mounting platform 2 to face or face away from the focus picture 4.

[0028] In this embodiment, during the test, the mobile phone 100 is placed and fixed on the mounting platform 2, and the upper end of the mobile phone 100 extends out of the mounting platform 2 so as not to block the shooting of the mobile phone 100. The rotating drive member 3 can drive the mounting platform 2 to rotate, thereby driving the mobile phone 100 to rotate. When the back of the mobile phone 100 faces the focus picture 4 and the front of the mobile phone 100 faces away from the focus picture 4, the rear camera of the mobile phone 100 takes the focus picture 4 to detect the focus quality of the rear camera. The rotating drive member 3 then drives the mounting platform 2 to rotate, so that the mobile phone 100 is inverted. Then, when the front of the mobile phone 100 faces the focus picture 4 and the back of the mobile phone 100 faces away from the focus picture 4, the front camera of the mobile phone 100 takes the focus picture 4 to detect the focus quality of the front camera. This testing method can reduce manual participation, thereby reducing labor costs, and can improve the efficiency of the test, and is highly practical.

[0029] In this embodiment, the mobile phone front and rear camera shooting focus testing device further includes an adsorption mechanism 5 , which is provided on the mounting platform 2 , and is used to adsorb and fix the mobile phone 100 on the mounting platform 2 .

[0030] The adsorption mechanism 5 can firmly fix the mobile phone 100 on the mounting platform 2 , so that when the rotating driving member 3 drives the mounting platform 2 to rotate, the mobile phone 100 will not fall and the position remains stable, thereby ensuring smooth testing.

[0031] Preferably, the adsorption mechanism 5 includes a vacuum suction cup 51 , and the vacuum suction cup 51 is provided on the mounting platform 2 for adsorbing and fixing the mobile phone 100 on the mounting platform 2 .

[0032] That is, the vacuum suction cup 51 can generate negative pressure, so that the mobile phone 100 can be firmly adsorbed on the mounting table 2, and the installation method of the mobile phone 100 is simpler and faster. At the same time, fixing the mobile phone 100 by negative pressure adsorption can reduce the wear and tear on the appearance of the mobile phone 100 compared to the existing technology using a clamp, ensuring that the appearance of the mobile phone 100 is not scratched during the testing phase.

[0033] Furthermore, a mounting opening 21 is provided on the mounting platform 2, and the mounting opening 21 passes through two opposite sides of the mounting platform 2. The adsorption mechanism 5 also includes a mounting bracket 52, and the mounting bracket 52 is detachably connected to one side of the mounting platform 2 and is located at one end of the mounting opening 21. The vacuum suction cup 51 is adapted to be embedded in the mounting opening 21 from the other end of the mounting opening 21, and the vacuum suction cup 51 is detachably connected to the mounting bracket 52.

[0034] Specifically, the mounting bracket 52 is fixed to the mounting platform 2 by screws, and the mounting bracket 52 does not completely enclose the mounting opening 21. The vacuum suction cup 51 is fixed to the mounting bracket 52 by screws. The vacuum suction cup 51 is embedded in the mounting opening 21, which ensures the stability of the vacuum suction cup 51 on the mounting platform 2. The vacuum suction cup 51 does not protrude too much from one side of the mounting platform 2, thereby facilitating the stable fixation of the mobile phone 100 on the mounting platform 2. In addition, the mounting bracket 52 is provided with an avoidance hole 53, so that the side of the vacuum suction cup 51 facing away from the mobile phone 100 can be connected to an external vacuum machine through the avoidance hole 53, making the installation more convenient.

[0035] In this embodiment, one end of the vacuum suction cup 51 away from the mounting bracket 52 extends out from the mounting opening 21 .

[0036] That is, the vacuum suction cup 51 protrudes from one side of the mounting platform 2 so that after the mobile phone 100 is placed on the mounting platform 2, it can ensure that the mobile phone 100 is in contact with the vacuum suction cup 51, thereby ensuring the stability of the position of the mobile phone 100.

[0037] In some embodiments, one end of the vacuum suction cup 51 away from the mounting bracket 52 is flush with a side of the mounting platform 2 away from the mounting bracket 52 .

[0038] That is, after the mobile phone 100 is placed on the mounting platform 2 , the mobile phone 100 is in contact with both the mounting platform 2 and the vacuum suction cup 51 , thereby increasing the contact area and ensuring the stability of the position of the mobile phone 100 .

[0039] In this embodiment, a plurality of hollow holes 22 are formed on the mounting platform 2 , thereby reducing the weight of the mounting platform 2 and facilitating the reduction of the load on the rotary drive member 3 .

[0040] In this embodiment, a mounting frame 6 is further included. The mounting frame 6 is spaced apart from the support frame 1. The focus picture 4 is arranged in the mounting frame 6, so that the focus picture 4 can be positioned and fixed, and the flatness of the focus picture 4 is ensured to ensure a smooth focus test.

[0041] Preferably, an LED light is provided in the mounting frame 6 to ensure illumination so that the camera of the mobile phone 100 can take clear pictures.

[0042] In this embodiment, the rotary driving member 3 is a rotary motor, which is fixed on the support frame 1 . The output end of the rotary motor is connected to the mounting platform 2 , thereby driving the mounting platform 2 to rotate.

[0043] like Figure 5As shown, in this embodiment, the mounting frame 6 is tilted, and the tilt angle of the mounting frame 6 to the vertical plane is 5°, that is, the focus picture 4 is tilted. When testing, the mounting platform 2 is initially in a horizontal state, so that the mobile phone 100 can be stably placed and fixed on the mounting platform 2. Then, the rotating motor drives the mounting platform 2 to rotate upward by 95°, so that the back of the mobile phone 100 faces the focus picture 4. The distance between the mobile phone 100 and the focus picture 4 is 414.75mm, and the rear camera of the mobile phone 100 is facing the focus picture 4 for shooting. The focus function of the rear camera is tested, and then the rotating motor drives the mounting platform 2 to continue rotating 180° in the same direction, that is, the front and back of the mobile phone 100 are inverted. At this time, the front of the mobile phone 100 is facing the focus picture 4, and the front camera of the mobile phone 100 is facing the focus picture 4 to shoot, so as to test the focus function of the front camera. That is, since the mounting frame 6 and the focus picture 4 are tilted, the mobile phone 100 is also tilted accordingly when shooting, so that the mobile phone 100 can face the focus picture 4, which can make the focus picture 4 taken by the mobile phone 100 more comprehensive.

[0044] Since when the mobile phone 100 takes the focus picture 4, in order to be able to capture the full focus picture 4, the mobile phone 100 and the focus picture 4 must maintain a sufficient distance. When the mobile phone 100 and the focus picture 4 are set at an interval in the upper and lower directions, too much space will be occupied in the height direction. When the mobile phone 100 and the focus picture 4 are set at an interval in the horizontal direction, too much space will be occupied in the horizontal direction. Therefore, in order to avoid the focus test device for the front and rear cameras of the mobile phone from being too large in a single direction, the mounting frame 6 and the focus picture 4 are set at an angle to balance the size of the focus test device for the front and rear cameras of the mobile phone in the horizontal and height directions.

[0045] like Figure 6 As shown, in this embodiment, the focus picture 4 is printed with multiple square patterns and two triangular patterns, so that after the mobile phone 100 takes the photo, it can derive the focus effect of the camera based on the clarity of the square patterns and the triangular patterns on the photo. The purpose of setting the two triangular patterns is to distinguish whether the focus picture 4 taken by the camera is taken upside down. The above is only a preferred embodiment of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present utility model. These improvements and replacements should also be regarded as the scope of protection of the present utility model.
