[0021] Combination Figures 2 to 3 As shown, in this embodiment, the frame 1 includes a working chamber suitable for accommodating the first working platform 2 and the second working platform 3, the first CCD mechanism 4 and the second CCD mechanism 5, and the frame 1 also includes a shell to prevent dust from entering; a loading port 6 is arranged in front of the frame 1, and the loading position of the first working platform 2 and the second working platform 3 is located at the loading port 6, which can be loaded manually or by a robot. A control machine is also arranged in the frame 1, and the control machine includes the control system, which can be used to coordinate and control various moving parts on the one hand, and can also receive photo data taken by a CCD camera on the other hand, and analyze and identify the photo data. When it is identified that the material has defects, an alarm device can be used to remind. In addition, a display screen 7 is also arranged on the frame 1 to display detection data and working status data. The material described in this embodiment can be a display screen.

[0022] The frame 1 is provided with a first slide rail 8 and a second slide rail 9 suitable for installing the first working platform 2 and the second working platform 3 in parallel, and the first slide rail 8 is provided above the second slide rail 9. Here, the first working platform 2 is switched between the detection position and the loading position through the first slide rail 8, and the second working platform 3 is switched below the loading position and the detection position through the second slide rail 9. A lifting cylinder 10 is provided on the second working platform 3, which is used to lift the second working platform 3 after it moves to the loading position or below the detection position. When it is lifted at the loading position, it is convenient to discharge the material. When it is lifted at the detection position, it can be flush with the first working platform 2, so that the detection positions are the same, and there is no need to adjust the focal length of the CCD camera, so as to ensure that the position of each detection is the same.

[0023] The first CCD mechanism 4 and the second CCD mechanism 5 are arranged below the second working platform 3, and are connected with a motion device for driving the first CCD mechanism 4 and the second CCD mechanism 5 to move synchronously, so that the edge inspection can be performed along the edge of the material. The motion mechanism 11 here can be a linear motion mechanism 11, and the user can fix a certain edge for inspection, or an XY axis motion mechanism 11 can be used, so that the inspection can be performed along two adjacent edges. In another embodiment, an adjustment platform 12 is respectively provided on the first CCD mechanism 4 and the second CCD mechanism 5 to adjust the shooting angle of the CCD camera. The adjustment platform 12 here can be set as a fixed plate and a fixing member, and the fixed plate is provided with an arc groove, and the CCD camera is fixed in the arc groove by the fixing member. When adjusting, first loosen the fixing member to fix the CCD camera, and then adjust the angle of the CCD camera. After the adjustment is completed, it can be fixed by the fixing member. The edge inspection device can adapt to more detection requirements and detection angles through the adjustment platform 12.

[0024] In this embodiment, the first CCD mechanism 4 is perpendicular to the plane where the material is located, and the second CCD mechanism 5 is inclined to the plane where the material is located. Through this solution, two orientations of image detection can be performed at the same detection point, and the two can verify each other to ensure the accuracy of the detection.

A point light source 14 is arranged on each of the first CCD mechanism 4 and the second CCD mechanism 5 to improve the detection effect.

Here, the third CCD mechanism 15 and the fourth CCD mechanism 16 are arranged the same as the first CCD mechanism 4 and the second CCD mechanism 5, except that the third CCD mechanism 15 and the fourth CCD mechanism 16 are used to detect one side of the material, while the first CCD mechanism 4 and the second CCD mechanism 5 are used to detect the other side of the material, and both sides can be detected simultaneously during operation to improve detection efficiency.

[0027] Through the solution of this embodiment, the efficiency and accuracy of border patrol detection are improved.
