Both the shoe 420 and the sled 410 can be made of antistatic materials, such as: PP, PE, PVDF and other plastics. The influence of static electricity generated during testing on the testing result can be avoided.
In this embodiment, the structure of the second detection plate 500 is the same as that of the first detection plate 400, and is not described herein again. The second detecting plate 500 is mounted on the first rail 230 and is slidably disposed on the mounting plane 210 along the first rail 230. Namely, the first and second checking plates 400 and 500 are slidably disposed on the mounting plane 210 in the same direction. It is understood that in other embodiments, the extending direction of the first track 220 and the extending direction of the first track 230 may be different.
It is understood that the first and second detection plates 400 and 500 may be slidably disposed on the mounting surface of the base 200 in other forms, for example, a sliding groove may be disposed on the mounting surface to cooperate with the first and second detection plates 400 and 500. In other embodiments, the first detection plate 400 and the second detection plate 500 may be detachably disposed on the base 200, and at this time, the relative positions of the first detection plate 400 and the second detection plate 500 with respect to the mounting base 300 may also be adjusted.

The mounting plane 210 may not be provided with the first rail 220 and the first rail 230 at this time.
In this embodiment, the first and second detection plates 400 and 500 are framed by a camera attached to the attachment portion 620 for convenience. The plane where the first detection plate 400 is located and the plane where the second detection plate 500 is located are both arranged to be parallel to the attaching surface 631, so that in the process of framing the first detection plate 400 and the second detection plate 500, the camera can be over against the first detection plate 400 or the second detection plate 500, and framing is more accurate. The plane of the first detection plate 400 and the plane of the second detection plate 500 are both the plane of the slide plate 410.
The first and second inspection plates 400 and 500 are disposed on the mounting plane 210 in a staggered manner along the first direction X. Wherein, the staggered arrangement along the first direction X means that: the first and second inspection plates 400 and 500 are arranged non-side by side in the first direction X. That is, the plane of the first test plate 400 and the plane of the second test plate 500 are not coplanar. It is understood that during the sliding of the first detection plate 400 and the second detection plate 500 relative to the base 200, the plane of the first detection plate 400 and the plane of the second detection plate 500 may be coplanar.
In some embodiments, the distance between the first detection plate 400 and the mounting base 300 is not equal to the distance between the second detection plate 500 and the mounting base 300, so that the camera can correspond to a close-up mode and a far-up mode of the camera when shooting the first detection plate 400 and the second detection plate 500. For example: when the distance between the first detection plate 400 and the mounting base 300 is smaller than the distance between the second detection plate 500 and the mounting base 300, the camera corresponds to the close-up mode when shooting the image of the first detection plate 400, and corresponds to the long-range mode when shooting the image of the second detection plate 500.
The working principle of the camera focusing device provided in the embodiment is as follows: during testing, an operator loads the electronic equipment into the fixing groove 650 from the notch 651, and a camera of the electronic equipment is made to leak from the notch 651. The first and second inspection plates 400 and 500 are adjusted to appropriate positions, for example, to a near view or a far view position, respectively. And controlling the camera to move along the first direction X to be opposite to the first detection plate 400, imaging the first detection plate 400, and detecting the imaging quality. Then, the movable fixing part 600 slides along the first direction X, and after the movable fixing part slides to the second detection plate 500 to be opposite, the second detection plate 500 is imaged, the imaging quality is detected, and the whole testing process is completed. And performing corresponding processing on the electronic equipment according to the detection result.

For example, the sliding groove 313 has a first end 3131 and a second end 3132 opposite to each other, and the first end 3131 corresponds to the first sensing plate 400, so that the fixing portion 600 is opposite to the first sensing plate 400 when the fixing portion 600 slides to the first end 3131. The second end 3132 corresponds to the second sensing plate 500 such that the fixing portion 600 is opposite to the second sensing plate 500 when the fixing portion 600 slides to the second end 3132. With this arrangement, the operator only needs to slide the fixing portion 600 to the two ends of the sliding groove 313, and does not need to visually determine the correspondence between the fixing portion 600 and the first and second detection plates 400 and 500.
In other embodiments, the length of the sliding groove 313 may be longer, and at this time, a corresponding limit may be disposed on the sliding groove 313 to limit the sliding distance of the fixing portion 600, so as to accurately position the fixing portion 600.
In other embodiments, the fixing portion 600 may be slidably disposed on the mounting base 300 along the first direction X in other manners. Referring to fig. 6 and 7, the mounting plate 310 may be provided with a slide rail 314, the slide rail 314 extends along a first direction X, the slider 610 has a mounting hole 613, the mounting hole 613 is matched with the slide rail 314, an axis of the mounting hole 613 is parallel to the first direction X, and the mounting hole 613 penetrates through the slider 610 along an axial direction thereof. During assembly, the assembly hole 613 is sleeved on the guide rail, and the assembly hole 613 is in clearance fit with the slide rail 314, so that the slider 610 can freely slide along the slide rail 314.
Referring to fig. 8, the sliding rail 314 has a first end 3131 and a second end 3132 opposite to each other, and the first end 3131 corresponds to the first test pattern 400, such that when the fixing portion 600 slides to the first end 3131, the fixing portion 600 is opposite to the first test pattern 400. The second end 3132 corresponds to the second sensing plate 500 such that the fixing portion 600 is opposite to the second sensing plate 500 when the fixing portion 600 slides to the second end 3132. With this arrangement, an operator only needs to slide the fixing portion 600 to the two ends of the slide rail 314, and does not need to visually determine the corresponding relationship between the fixing portion 600 and the first and second inspection plates 400 and 500.
