In addition, a glass platform 2 is arranged in the machine body 1, and a diaphragm is placed on the glass platform 2.
In this embodiment, in order to better fix the diaphragm, a layer of glass cover may be further covered on the glass platform 2, so that the diaphragm is clamped between the glass platform 2 and the glass cover, and when the diaphragm on the front surface of the diaphragm needs to be detected, the front surface of the diaphragm is clamped between the glass platform 2 and the glass cover; if the membrane on the opposite side of the membrane is to be tested, the opposite side of the membrane is clamped up between the glass platform 2 and the glass cover.
In order to better move the glass cover, as shown in fig. 2, the glass cover may be connected to the glass platform 2 through a damping hinge 3, and the glass cover may be driven to realize opening and closing movement under the action of the hinge. In addition, the damping hinge 3 can also be a limiting hinge with a limiting function, and is used for limiting the moving range of the glass cover; when the limiting hinge moves to a maximum angle, the glass cover is far away from the glass platform 2, so that the diaphragm on the glass platform 2 can be adjusted and replaced; the glass cover and the glass platform 2 remain horizontal when the limit hinge is moved to a minimum angle, thereby limiting the membrane between the glass cover and the glass platform 2.
The diaphragm is placed on glass platform 2 by artifical level, then covers glass, and glass size is 600 by 700 by 10mm, and glass adopts damping hinge 3 to connect, takes mechanical spacing to prevent glass collision, places and starts equipment after leveling.
The equipment is also provided with a light source module 4 and a multi-axis truss, wherein the light source module 4 comprises a light source body and a light source bracket, and the light source body is fixed on the machine body 1 through the light source bracket so as to transversely span the width direction of the glass platform 2; meanwhile, a rotating shaft is further arranged on the light source support, and the light source body is connected with the rotating shaft, so that the light source body can rotate along the rotating shaft to enable light emitted by the light source body to irradiate on the width direction of the glass platform 2 at an inclined angle.
The machine body 1 is also internally provided with a multi-axis truss, in this embodiment, the multi-axis truss comprises a truss driving motor 5, an X-axis frame 6 and a Y-axis beam 7, and the Y-axis beam 7 is positioned in the width direction of the glass platform 2 and is movably connected with the X-axis frame 6; the camera 8 is mounted on the Y-axis beam 7, and the camera 8 can move back and forth along the Y-axis beam 7, so that the camera 8 stays at a designated position of the Y-axis beam 7 in the moving process of the camera 8 along the Y-axis beam 7, and the shooting width of the camera 8 is ensured to cover the glass platform 2, so that the diaphragm on the glass platform 2 can be completely shot to form an image.

In some embodiments, the light source module 4 is further provided with a light source driving motor for driving the light source module 4 to rotate along an axis, so as to change the angle of the light emitted by the light source module 4 to the glass platform 2. In order to better scan a clear diaphragm image, the rotation angle of the light source body and the position of the camera 8 on the glass platform 2 can be coordinated by the controller, so that the normal line of the light emitted by the light source module 4 to the glass platform 2 always coincides with the shooting direction of the camera 8, as shown in fig. 3, the downward shooting direction of the camera 8 in fig. 3 coincides with the normal line of the light beam emitted by the light source module 4, and therefore the shooting quality is improved.
As shown in fig. 4, the detection starts after the device is started, the device encoder counts and photographs, performs preprocessing on the image to divide the discrimination area, and then performs image analysis on the discrimination area to obtain a detection result.
