Flatness within the design specifications can ensure that the structure is more evenly stressed. If the flatness does not meet the standards, it will lead to uneven stress on various parts of the thermosetting composite board.

[0024] For the convenience of those skilled in the art to fully understand the specific structure and principle of the composite plate lifting mechanism 4, a further description of the composite plate lifting mechanism 4 is made. In this embodiment, the composite plate lifting mechanism 4 includes a lifting opening 401, which is arranged in the middle of the inspection machine tool 1. A fixed bottom frame 402 is arranged at the bottom of the lifting opening 401. The top of the fixed bottom frame 402 is connected to the bottom of the inspection machine tool 1. A rotating clamping hole 403 is arranged at the bottom of the fixed bottom frame 402. A rotating sleeve 404 adapted thereto is rotatably arranged on the inner wall of the rotating clamping hole 403. Meshing teeth 405 are evenly arranged on the outer peripheral surface of the bottom of the rotating sleeve 404. A transmission gear 406 is meshed and connected to one side of the meshing teeth 405. A third servo motor 407 is arranged on the top of the fixed bottom frame 402. The driving end of the third servo motor 407 is clamped and fixed to the transmission gear 406.

The top of the bottom support plate 411 is rotatably connected to the top support plate 413 through a rotating shaft 412.

[0025] Specifically, when initially fixing the thermosetting composite plate, the flatness of the top, bottom, and two sides of the thermosetting composite plate can be detected. When detecting the remaining two sides, it is installed at the bottom of the lifting opening 401 through the fixed bottom frame 402. The third servo motor 407 drives the transmission gear 406 to rotate. The transmission gear 406 drives the rotating sleeve 404 to rotate on the inner wall of the rotating clamping hole 403 through the meshing teeth 405. The rotating sleeve 404 is connected to the threaded rod 409 through the threaded hole 408, so as to conveniently drive the threaded rod 409 to perform lifting adjustment. The threaded rod 409 is prevented from coming out through the limiting circular plate 410. The threaded rod 409 is connected to the bottom support plate 411, thereby driving the bottom support plate 411 to lift. The bottom support plate 411 drives the top support plate 413 to rotate and adjust through the rotating shaft 412. After the first round of detection, the limitation of the thermosetting composite plate is released. The threaded rod 409 jacks up the bottom support plate 411 to the top of the retracted laser measuring instrument 237. The thermosetting composite plate is manually rotated and the position is adjusted. Then the composite plate limiting mechanism 3 limits the thermosetting composite plate. One group of laser measuring instruments 237 detects the flatness of the remaining side surface. After the detection, repeat the above steps to adjust the position and continue to detect the flatness of the last side surface, so as to realize the detection of the flatness of the six surfaces of the thermosetting composite plate, thereby improving the integrity of the detection.

[0026] Working principle: First, the thermosetting composite board is supported by the composite board lifting mechanism 4, and the composite board limiting mechanism 3 facilitates its fixation. The laser detection mechanism 2 facilitates the detection of the surface flatness thereof. The movable clamp 231 is slidably clamped on both sides of the detection machine tool 1 through the movable chute. The first support plate 232 mounts the first servo motor 233. The first servo motor 233 drives the first gear 234 to rotate. The engagement of the first gear 234 with the first rack 202 facilitates the linear movement of the movable clamp 231. The limit clamping plate 204 prevents the movable clamp 231 from disengaging. The lifting support plate 236 is conveniently slidably limited on the inner wall of the fixed housing 235 through the arranged limiting rod 242 and the limiting block 243. The second support plate 240 supports the second servo motor 241. The second servo motor 241 drives the second gear 239 to rotate. The engagement of the second gear 239 with the second rack 238 further facilitates driving the lifting support plate 236 to perform lifting adjustment, and further facilitates driving the laser measuring instrument 237 to flexibly adjust the position according to the thickness and length of the thermosetting composite board, facilitating the detection of the flatness of the upper and lower surfaces and the surface flatness of the side surface of the thermosetting composite board. Two groups of laser measuring instruments 237 are provided, with one group scanning the upper part and the other group scanning the lower part, which can improve the detection efficiency.

[0027] The supporting vertical plate 301 can prevent the moving carriage 304 on the guide rail 302 from slipping out through the limiting plate 303. The first air cylinder 305 drives the moving carriage 304 to adjust the lifting, which facilitates driving the limiting clamping plate 307 to move inward by the second air cylinder 306 to clamp and fix the thermosetting composite board. The anti-slip convex blocks 308 can increase the friction force of the limiting clamping plate 307, thereby improving the clamping stability, facilitating clamping and lifting the thermosetting composite board placed on the top of the composite board lifting mechanism 4, and facilitating the laser measuring instrument 237 to detect the surface of the thermosetting composite board. When initially fixing the thermosetting composite board, the flatness of the top, bottom and two sides of the thermosetting composite board can be detected. When detecting the remaining two sides, it is installed at the bottom of the lifting opening 401 through the fixed chassis 402. The third servo motor 407 drives the transmission gear 406 to rotate. The transmission gear 406 drives the rotating sleeve 404 to rotate on the inner wall of the rotating card hole 403 through the meshing teeth 405. The rotating sleeve 404 is connected with a threaded rod 409 through the threaded hole 408, thereby facilitating driving the threaded rod 409 to adjust the lifting. The threaded rod 409 is prevented from slipping out through the limiting circular plate 410. The threaded rod 409 is connected with the bottom support plate 411, thereby driving the bottom support plate 411 to lift. The bottom support plate 411 drives the top support plate 413 to rotate and adjust through the rotating shaft 412. After the first round of detection, the limit on the thermosetting composite board is released. The threaded rod 409 jacks up the bottom support plate 411 to the top of the retracted laser measuring instrument 237. The thermosetting composite board is manually rotated and the position is adjusted. Then the composite board limiting mechanism 3 limits the thermosetting composite board. One group of laser measuring instruments 237 detects the flatness of the remaining side surface. After the detection, repeat the above steps to adjust the position and continue to detect the flatness of the last side surface, so as to realize the detection of the flatness of the six surfaces of the thermosetting composite board, thereby improving the integrity of the detection.

Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present invention shall not depart from the essence and scope of the technical solution of the present invention.
