[0018] exist Figure 1 and Figure 2 In the middle, the front and rear sides of the fixed plate 401 are connected to the inner walls of the front and rear sides of the base 1, respectively, and the movable plate 403 and the fixed plate 401 are on the same horizontal line.

[0019] exist Figure 1 and Figure 3 In this configuration, there are two first electric slide rails 402, and the front and rear sides of the movable plate 403 are slidably connected to the two first electric slide rails 402 respectively.

[0020] Specifically, by setting the first electric slide rail 402, the PLC controller drives the first electric slide rail 402 to start, thereby moving the moving plate 403 left and right, which facilitates limiting the plate of different lengths.

[0021] exist Figure 2 and Figure 3There are two sets of electric push rods 404. The two sets of electric push rods 404 are connected to the top of the moving plate 403 and the fixed plate 401 respectively. There are two electric push rods 404 in each set.

[0022] Specifically, when the moving plate 403 reaches the end of the board, the electric push rod 404 extends and drives the sponge pad 5 to move downward to press and limit the board.

[0023] exist Figure 2 and Figure 3 In the middle, a sponge pad 5 is fixedly installed at the bottom of the electric push rod 404, and electric slides 6 are fixedly installed on both the front and rear sides of the base 1. The two electric slides 6 are slidably connected to the two support plates 3 respectively.

[0024] exist Figure 2 and Figure 4 In the middle, an extension plate is fixedly installed on the top of the support plate 3, and the two support plates 3 are connected through the extension plate. The motor 405 is located inside the front support plate 3, and a limit rod is fixedly installed inside the rear support plate 3. The outside of the limit rod is sleeved on the sliding sleeve, and the side of the horizontal plate 408 away from the threaded sleeve 407 is connected to the sliding sleeve.

[0025] Specifically, by setting the motor 405, the PLC controller drives the motor 405 to start, which in turn drives the threaded rod 406 to rotate. At this time, due to the limit rod, the threaded sleeve 407 drives the horizontal plate 408 to move downward. The distance between the laser displacement sensor 409 and the plate is adjusted according to the plate thickness.

[0026] exist Figure 3 and Figure 5 In the middle, the second electric slide rail 7 is installed inside the horizontal plate 408, the top of the laser displacement sensor 409 is slidably connected to the second electric slide rail 7, and the PLC controller is fixedly installed on the front side of the base 1.

[0027] Among them, the laser displacement sensor series 409JC-ZW.

[0028] During implementation, the following steps are followed: First, place the material to be tested on conveyor belt 2. Conveyor belt 2 moves the material to the right. The PLC controller drives the electric push rod 404 on the fixed plate 401 to extend, causing the sponge pad 5 to move downwards, fixing the first end of the material. Then, the PLC controller drives the first electric slide rail 402 to start, causing the moving plate 403 to move left and right. When the moving plate 403 reaches the end of the material, the electric push rod 404 extends, causing the sponge pad 5 to move downwards, pressing and limiting the material. At this time, the PLC controller drives the motor 405 to start, and the rotating threaded rod 406 drives the horizontal plate 408 downwards through the threaded sleeve 407. The measurement range is selected from 25-600mm according to the thickness of the board. The sampling frequency is set to ≥9.4kHz when the movement speed is >1m / s. After the adjustment is completed, the PLC controller drives the electric slide table 6 to start, so that the support plate 3 drives the laser displacement sensor 409 to move at a constant speed to cover the entire board, thereby realizing efficient detection of the flatness of the board. The four corners and the center point of the board are selected as reference measurement points. Data is collected 10 times continuously at each measurement point and the average value is taken. When the board is uneven, an alarm is issued and the board can be removed. Finally, after the detection is completed, the electric push rod 404 drives the sponge pad 5 to rise. At this time, the conveyor belt 2 drives the qualified board forward.

[0029] In summary, by setting up the first electric slide rail 402, the PLC controller drives the first electric slide rail 402 to start, thereby moving the moving plate 403 left and right, which facilitates the limiting of plates of different lengths. When the moving plate 403 reaches the end of the plate, the electric push rod 404 extends and moves the sponge pad 5 downward to press and limit the plate. By setting up the motor 405, the PLC controller drives the motor 405 to start, which drives the threaded rod 406 to rotate. At this time, due to the limitation of the limiting rod, the threaded sleeve 407 drives the horizontal plate 408 to move downward. According to the plate of different thicknesses, the distance between the laser displacement sensor 409 and the plate is adjusted. After the adjustment is completed, the PLC controller drives the electric slide table 6 to start, so that the support plate 3 drives the laser displacement sensor 409 to move at a constant speed to cover the entire plate, thereby realizing the efficient detection of the flatness of the plate.
