Description

Technical Field

[0001] This invention relates to the field of corrugated steel web plate inspection technology, specifically to a device for inspecting and correcting the forming dimensions of corrugated steel web plates. Background Technology

[0002] During the production of corrugated steel webs, due to the ductility of the steel and the residual stress, the corrugated steel webs produced by pressing exhibit positional differences. Residual compressive stress remains on the inner surface of the steel plate at the bend, while residual tensile stress remains on the outer surface. These errors gradually accumulate, eventually causing the cut length to be shorter or longer. The bends are often curved, making it impossible to measure the spacing between the curves. At this point, workers will use markings made before pressing to make approximate measurements. To ensure accurate spacing between the curves, inspection and correction become crucial.

[0003] In existing technology, regarding the distance between the arcs after the corrugated steel web is formed, workers typically locate the axis on the corrugated steel web before forming by marking it with chalk. Then, workers use a ruler to measure these distances. If the measured dimensions are roughly consistent, the forming is considered qualified. Then, the next step is taken based on the length of the remaining straight segments on both sides. If the last straight segment is long, it will be cut according to the welding length to be spliced ​​with the next segment to adapt to the actual situation. If the straight segment is short, then this section of the corrugated steel web is discarded and cannot be formed a second time.

[0004] However, the following shortcomings still exist. As can be seen from the above statements, due to the ductility and residual stress of steel, the spacing between the arc corners will be inconsistent during the forming process, which will affect the dimensional accuracy. For the standard cutting length, the ductility of steel will cause it to shift to both ends, resulting in the leftmost and rightmost reserved distances not meeting expectations. Long-term cutting will greatly reduce the utilization rate of materials. If compensation is made, the strength and stiffness of the joint will be affected, affecting its load-bearing capacity and stability. Moreover, traditional manual measurement methods have problems such as strong subjectivity, low accuracy and efficiency, which cannot meet the requirements of modern engineering for high precision and high efficiency of steel structure components.

[0033] Based on the above embodiments, such as Figure 2 As shown, a telescopic horizontal frame 12 is installed inside the corrugated steel web press, and a lifting plate 11 is installed on the telescopic horizontal frame 12. A first jack 28 is installed inside the corrugated steel web press.

[0034] In this embodiment, the PLC control module 17, the laser engraving module 10, the camera module 13, and the image processing computer 19 are all existing technologies. The PLC control module 17 adopts S7-200, the laser engraving module 10 adopts AMF30H, and the clamp module 4 adopts a sliding clamp.

[0035] like Figure 6 As shown, the workflow of the corrugated steel web forming dimension inspection and correction device is as follows: Step 1: Install the device and perform laser engraving Currently, corrugated steel webs used in bridges are generally made by pressing a straight plate into three corrugations. During manufacturing, the first corrugation is pressed first, then the second is pressed forward and pressed, and so on until the last corrugation is pressed. At the beginning, laser marking is performed on a flat steel plate. Reference lines are marked on the corrugated steel web to be pressed. The principle of marking positions is to calculate the positions that should be marked before marking based on the marked positions. This is based on the reverse derivation of the corrugation design and the laser marking positions. Taking a 5000T corrugated steel web press as an example, and the corrugated steel web as a 1600 type, the parameters of the corrugated steel web (wavelength, wave height, wave number) are first input into the image processing computer 19 to calculate the cutting length and marking positions. This is achieved by relying on transmission... The drive system drives the laser engraving module 10 to accurately position itself according to the parameters of the corrugated steel web, and pushes the slider 12 to perform laser engraving. The positions marked before forming are mainly at the left and right positions and the midline of any two bends in the corrugated steel web after forming. The specific process of the drive system driving the laser engraving module 10 is as follows: the electric push rod 21 is started, which drives the slider rod 16 to move. The movement of the slider rod 16 drives the data acquisition module 14 and the LED light strip 15 to move on the one hand, and drives the laser engraving module 10 and the camera module 13 to move to the position where the engraving is required on the other hand. The movement distance is controlled by the PLC control module 17 to ensure the accuracy of the movement, and straight lines are engraved on the corrugated steel web. Step 2: Use machine vision technology to identify and number the tags. Next, the camera module 13 adjusts the focus and lighting to take pictures and acquire images with markings. The images are then input into the operating system of the touch-screen image processing computer 19 for image enhancement. Using the Hough transform function and edge detection function in OpenCV, the camera accurately identifies the previously made markings and automatically numbers them. The PLC control module 17 controls the data acquisition module 14 to move to each marking location and measure the wavelength BC, wavenumber BS, peak height BG, and trough depth BD. The parameters are then transmitted to the image processing computer 19 via WIFI. Step 3: Calculate the composite index During the molding process, the height of the wave does not change, but the width of the wave will change to a certain extent. Since both sides are arcs, the distance between BC is arc-shaped, which is difficult for workers to measure. By analyzing and processing the spatial parameters and amplitude parameters, a comprehensive index can be calculated and then corrected. Based on image processing, the data acquisition module 14 is fixed at the edge. The data acquisition module 14 is aligned with each line according to the line number to measure the spatial parameters and amplitude parameters respectively, and displayed on the human-computer interaction interface 34. This comprehensive index will be used for feedback correction in subsequent operations. Step 4: Feedback and Correction The comprehensive index ZS and the forming size threshold YZ of the corrugated steel web are compared inversely, and a feedback correction operation is performed. If the forming size of the corrugated steel web does not meet the standard, the information is fed back to the image processing computer 19 based on the difference between the comprehensive index ZS and the forming size threshold YZ. Based on the feedback from the image processing computer 19, the corrugated steel web can be placed in the gripper module 4 by the robotic arm. The image processing computer 19 controls the fine adjustment. Then, according to the size, the adjustable height second jack 29 is used. The lifting height of the second jack 29 is controlled by the PLC system, which controls the flipping angle of the gripper module 4. The gripper module 4 rotates inward around the hinge bolt shaft 6 on the left side to correct the corrugated steel web.

[0036] α, β, in the formula , , and The specific values ​​are generally determined by those skilled in the art based on the actual situation. This formula is essentially a weighted summation for comprehensive analysis. Those skilled in the art collect multiple sets of sample data and set corresponding preset proportion coefficients for each set. The preset proportion coefficients and the collected sample data are substituted into the formula, and the calculated coefficients are filtered and averaged to obtain α, β, and . , , and The value of .

[0037] In addition, the size of the preset factor coefficient is a specific value obtained by quantifying each parameter. In order to facilitate subsequent comparison, the size of the coefficient depends on the amount of sample data and the preset ratio coefficient initially set by those skilled in the art for each set of sample data. It is not unique, as long as it does not affect the ratio relationship between the parameter and the quantified value.
