[0002] The traditional method of measuring plate flatness is the discrete point method, and multiple points are selected for flatness measurement. This method has less measurement data, and the reflected surface flatness may be quite different from the actual situation. The detection data is not accurate, and the detection efficiency Low
Traditional detection devices are generally only used to detect the overall condition of the flatness of the plate, and cannot accurately locate the unqualified point

Embodiment Construction
[0047] The automatic flatness detection device and detection method of the present invention will be described in detail below in conjunction with the embodiments and drawings.
[0048] Such as figure 1 As shown, the automatic flatness detection device of the present invention includes a rectangular support frame A. A pair of parallel first frame 16 and second frame 17 of the rectangular support frame A is provided with a guide frame B and drives the The guide frame B is capable of moving along the first frame 16 and the second frame 17 with a first driving mechanism C. The guide frame B is provided with a movable sliding table 3 and drives the movable sliding table 3 to move along the guide frame B. The second driving mechanism D for the movement of the guide rod, the moving slide 3 is provided with a detection head 6 for flatness detection, and a third driving mechanism E for driving the detection head 6 to move up and down.
[0049] The guide frame B includes a first side frame ...

The invention discloses an automatic flatness detection device and method. According to the device, a guide frame and a first driving mechanism are arranged between a pair of a first frame and a second frame parallel to each other on a rectangular support frame, wherein the first driving mechanism can drive the guide frame to move along the first frame and the second frame; a movable sliding table and a second driving mechanism which can drive the movable sliding table to move along a guide rod on the guide frame are arranged on the guide frame; and a detection head used for detecting the flatness and a third driving mechanism capable of driving the detection head to move up and down are arranged on the movable sliding table. The method comprises the following steps: arranging a to-be-detected plate on the detection head; enabling the detection head to enter a to-be-detected plate breadth detection phase; resetting the detection head; enabling the detection head to stably slide on the surface of the to-be-detected plate according to a given path, and drawing a data change curve in real time by an upper computer; replacing the detection head and mounting a mark pen after the detection is completed; and positioning detection platforms one by one according to coordinate positions recorded in the detection process, and marking unqualified positions. According to the device and method disclosed by the invention, the detection data volume is increased, so that the flatness detection is accurate and reliable.
Description
Technical field [0001] The invention relates to a detection device. In particular, it relates to an automatic flatness detection device and detection method. Background technique [0002] The traditional method of measuring plate flatness is discrete point type, and multiple points are selected for flatness measurement. This method has less measurement data, and the surface flatness reflected may be quite different from the actual situation, the detection data is not accurate, and the detection efficiency low. Traditional detection devices are generally only used to detect the overall flatness of the plate, and cannot accurately locate the unqualified points. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic flatness detection device and a detection method with higher detection efficiency, high autonomy, and accurate and intuitive detection data. [0004] The technical solution adopted by the present invention...
