[0023] Working principle: In use, the detection element is placed on the support plate 61. Pulling the pull block 622 causes the telescopic rod 621 to move and the limiting rod 623 to move out of the limiting hole 63. Pushing the pull block 622 causes the clamping bar 620 to move to the appropriate position via the telescopic rod 621. Pressing the pull block 622 returns the telescopic rod 621 to its original state and the limiting rod 623 to enter the limiting hole 63. The servo motor 22 is started, and the servo motor 22 drives the second internal threaded shaft plate 33 and the first internal threaded shaft plate 222 to move simultaneously via the screw 221, so that the second internal threaded shaft plate 33 is positioned on the support bar 321. The surface moves up and down, causing the CCD camera 331 to move up and down, thereby determining the position of the detection element on the positioning plate 5. After the position is determined, the first internal threaded shaft plate 222 drives the slide plate 212 to slide in the first slide groove 211, so that the laser displacement probe 213 contacts the bottom of the detection element. The Y-axis linear motor 41 is started, and the Y-axis linear motor 41 drives the mounting plate 4 to move longitudinally through the Y-axis linear platform 31. The X-axis linear motor 51 is started, and the X-axis linear motor 51 drives the positioning plate 5 to move laterally through the X-axis linear platform 42, so that the laser displacement probe 213 measures different positions of the detection element.

[0024] In summary, this high-precision flatness detection mechanism, through the cooperation of the L-shaped plate 2 and the connecting plate 3, activates the servo motor 22. The servo motor 22 drives the second internal threaded shaft plate 33 to move via the screw 221, causing the second internal threaded shaft plate 33 to move up and down on the surface of the support bar 321, thereby causing the CCD camera 331 to move up and down, thus determining the position of the detection element on the positioning plate 5. After the position is determined, the servo motor 22 drives the first internal threaded shaft plate 222 to move via the screw 221. The first internal threaded shaft plate 222 drives the slide plate 212 to slide in the first slide groove 211, so that the laser displacement probe 213 contacts the bottom of the detection element, thereby achieving a stable measurement effect. Through the cooperation of the connecting plate 3 and the mounting plate 4, the Y-axis linear motor 41 is activated. The mounting plate 4 is moved longitudinally by the Y-axis linear platform 31, and the X-axis linear motor 51 is started. The X-axis linear motor 51 moves laterally by the X-axis linear platform 42, so that the laser displacement probe 213 measures different positions of the detection element, thereby achieving accurate measurement. The detection element is placed on the support plate 61 by the cooperation of the positioning block 6 and the clamping strip 620. Pulling the pull block 622 moves the telescopic rod 621 and the limiting rod 623 out of the limiting hole 63. Pushing the pull block 622 moves the clamping strip 620 to the appropriate position through the telescopic rod 621. Pressing the pull block 622 restores the telescopic rod 621 to its original state and the limiting rod 623 enters the limiting hole 63, thereby achieving the effect of easy fixation.
