During the movement of the moving part, the position adjustment mechanism and the detection mechanism are driven to move synchronously to change the left and right position of the detection mechanism, so that it can comprehensively detect different positions of the plate. A sliding sleeve and a support frame are set at the bottom of the second shell. The sliding sleeve slides on the surface of the sliding rod, and the support frame moves on the left side of the first shell through the pulley to avoid shaking of the second shell when it moves back and forth, thereby improving the accuracy of the detection mechanism during detection.

[0024] 3.

The present invention is more convenient to detect the flatness of the upper and lower sides of the plate by setting a detection mechanism, and can detect the thickness and flatness of the side of the plate, thereby improving the comprehensiveness of the detection and increasing the production quality of the plate. When the detection mechanism is located at the top of the plate, the second cylinder drives the mounting plate to move downward, so that a plurality of contact measuring heads contact the top of the plate. After the contact measuring heads contact the plate, the pressure sensor detects the pressure exerted on the contact measuring heads through the elastic member. When the contact measuring heads move on the plate, the uneven surface of the plate will cause uneven force on the plurality of contact measuring heads. The pressure sensor transmits the detected pressure data to the control module. The control module detects the flatness of the plate surface according to the detected pressure data, and the auxiliary spring assists in resetting the contact measuring heads so that they can In order to keep in contact with the surface of the plate, and during the detection of the contact measuring head, the laser scanning measuring head emits a laser beam to the surface of the plate, and performs a secondary detection of the flatness of the plate surface through the reflected laser beam to improve the detection accuracy. When it is necessary to detect the side of the plate, the first cylinder drives the lifting plate to move downward, and the lifting plate drives the detection mechanism to move downward as a whole, and the third cylinder drives the connecting frame and the supporting platform to move upward, so that the plate moves upward, and the output shaft of the first self-locking motor drives the rotating rod to rotate, and the rotating rod drives the plate body to rotate ninety degrees, so that the contact measuring head and the laser scanning measuring head are aligned with the side of the plate. After the alignment is completed, the second cylinder drives the mounting plate to move to the left, so that the contact measuring head contacts the side of the plate, and detects the flatness of the side of the plate.

The plate is placed on the top of the support platform. After placement, the output shaft of the second self-locking motor drives the gear to rotate, the gear drives the rack to move, and the rack drives the two clamping assemblies to move to the front and rear sides of the plate to limit the plate. The front and rear sides of the plate contact the inner wall of the clamping platform, and the threaded rod is rotated. The threaded rod drives the clamp to move downward to clamp and fix the top of the plate. During the movement of the clamp, the connecting rod is driven to slide on the top of the clamping platform to limit the clamp. After the plate is fixed, the detection mechanism detects the plate. When the top detection of the plate is completed, the staff takes out the plate and turns the plate over for secondary fixing to achieve double-sided detection of the plate. When the detection of one side of the plate is completed, the staff continues to change the fixed position of the plate to detect the other sides of the plate. BRIEF DESCRIPTION OF THE DRAWINGS

The piston rod of the multi-section telescopic cylinder 204 can drive the moving part 205 to slide on the inner wall of the second shell 201. During the movement of the moving part 205, the position adjustment mechanism 300 and the detection mechanism 400 are driven to move synchronously, and the left and right positions of the detection mechanism 400 are changed, so that it can comprehensively detect different positions of the plate.

[0050] By setting up a position adjustment mechanism 300, the range of left and right movement of the detection mechanism 400 can be further increased, and the detection mechanism 400 can be driven to move up and down. The output shaft of the stepper motor 305 drives the second screw rod 308 to rotate on the inner wall of the third shell 301, and the second screw rod 308 drives the second nut sleeve 307 to slide on the inner wall of the third shell 301.

[0053] Furthermore, a mounting plate 403 is movably connected inside the plate body 404, a second cylinder 405 is fixedly connected to the rear side of the top of the mounting plate 403, the second cylinder 405 is fixedly installed on the rear side of the plate body 404, a laser scanning measuring head 414 is fixedly installed at the bottom of the mounting plate 403, and a support member 407 is fixedly connected to the top of the mounting plate 403.

[0054] Furthermore, a plurality of contact measuring heads 412 are provided at the bottom of the support member 407, and a limit frame 410 is movably sleeved on the surface of the contact measuring head 412, and a fixing member 409 is fixedly connected to the front side of the limit frame 410, and the fixing member 409 is fixedly installed on the front side of the support member 407, and an elastic member 411 is fixedly connected to the center of the top of the contact measuring head 412, and a pressure sensor 408 is fixedly installed on the top of the elastic member 411, and auxiliary springs 413 are fixedly connected to the left and right sides of the top of the contact measuring head 412, and the pressure sensor 408 and the top of the auxiliary spring 413 are fixedly connected to the bottom of the support member 407.

[0055] By setting up the detection mechanism 400, it is more convenient to detect the flatness of the upper and lower sides of the plate, and the thickness and flatness of the side of the plate can be detected, so as to improve the comprehensiveness of the detection and increase the production quality of the plate. When the detection mechanism 400 is located at the top of the plate, the second cylinder 405 drives the mounting plate 403 to move downward, so that a plurality of contact measuring heads 412 contact the top of the plate. After the contact measuring heads 412 contact the plate, the pressure sensor 408 detects the pressure exerted on the contact measuring heads 412 through the elastic member 411. When the contact measuring heads 412 move on the plate, the uneven surface of the plate will cause uneven force on the plurality of contact measuring heads 412. The pressure sensor 408 transmits the detected pressure data to the control module 104. The control module 104 detects the flatness of the plate surface according to the detected pressure data. The auxiliary spring 413 assists in resetting the contact measuring heads 412 so that it can maintain contact with the plate surface. During the detection process of the contact measuring head 412, the laser scanning measuring head 414 emits a laser beam to the surface of the plate, and performs a secondary detection on the flatness of the plate surface through the reflected laser beam to improve the detection accuracy. When it is necessary to detect the side of the plate, the first cylinder 303 drives the lifting plate 302 to move downward, and the lifting plate 302 drives the detection mechanism 400 to move downward as a whole, and the third cylinder 505 drives the connecting frame 502 and the supporting platform 501 to move upward, so that the plate moves upward, and the output shaft of the first self-locking motor 406 drives the rotating rod 402 to rotate, and the rotating rod 402 drives the plate body 404 to rotate ninety degrees, so that the contact measuring head 412 and the laser scanning measuring head 414 are aligned with the side of the plate. After the alignment is completed, the second cylinder 405 drives the mounting plate 403 to move leftward, so that the contact measuring head 412 contacts the side of the plate, and detects the flatness of the side of the plate. The laser scanning measuring head 414 emits a laser beam to detect the thickness of the side of the plate.

[0056] The contact measuring head 412 contacts the surface of the plate. A pressure sensor 408 is connected to the top of each contact measuring head 412 and connected through an elastic member 411. When the contact measuring head 412 contacts the surface of the plate, a certain pressure is generated. This pressure is transmitted to the pressure sensor 408 through the elastic member 411. The function of the elastic member 411 is to convert the contact force into a measurable pressure change, which can produce a linear force-displacement relationship. The pressure sensor 408 detects the pressure exerted on the contact measuring head 412 and transmits these data to the control module 104. The control module 104 receives the pressure data and determines the flatness of the plate surface according to the pressure change. If the surface of the plate is uneven, the pressure exerted on each contact measuring head 412 will be different. By comparing these pressure data, the height change of the plate surface can be determined. The auxiliary spring 413 is installed on the left and right sides of the top of the contact measuring head 412 to help the contact measuring head 412 to remain stable when contacting the surface of the plate and quickly reset after the detection is completed.

[0057] The laser scanning measuring head 414 emits one or more laser beams, which usually have high accuracy and directionality. When the laser beam hits the surface of the plate, a part of the light will be reflected back. The receiver in the laser scanning measuring head 414 will capture the reflected light beams. The receiver detects the intensity, phase and other information of the reflected laser beam. By analyzing the intensity change and time delay of the reflected light, the height change of the plate surface can be calculated. If the plate surface is flat, the intensity and phase changes of the reflected light are relatively consistent. If the plate surface is uneven, the intensity and phase of the reflected light will change. By scanning the plate surface with the laser scanning measuring head 414, three-dimensional point cloud data of the plate surface can be obtained. These point cloud data are fused and processed to generate a three-dimensional model of the plate surface, and the flatness and parallelism of the plate are further analyzed.

[0058] The contact measuring head 412 can detect subtle changes on the surface of the plate, while the laser scanning measuring head 414 can provide an overall three-dimensional model. The combination of the two can make up for each other's shortcomings and provide more complete data. By fusing the contact measurement data with the laser scanning data, a more accurate three-dimensional model can be generated to further analyze the flatness and parallelism of the plate.
