Technical Field
[0001] The present invention relates to the technical field of film thickness acquisition devices, and in particular to a film thickness acquisition device with AI autonomous learning graphics technology. Background Art
[0002] BOPP film, or biaxially oriented polypropylene film, is made by biaxial stretching. It is a plastic product that is specially formed and processed by physical, chemical and mechanical means. The BOPP production line is a complex system with nonlinearity, time-varying and large delay. Its process mainly includes: raw material melting, extrusion, cooling and molding, longitudinal stretching, transverse stretching, trimming, corona treatment, winding, etc.
[0003] The physical and mechanical properties of BOPP film products, such as tensile strength, elongation at break, turbidity, gloss, etc., which are the quality indicators of BOPP film products, are easy to meet the requirements because they are mainly determined by the properties of the material itself. As the main control indicators of reprocessability and performance, namely film thickness deviation and average film thickness deviation, they are mainly determined by the film manufacturing process. Even if the film thickness is controlled within the deviation range allowed by the standard during the manufacturing process, after thousands of layers of film are rolled up, defects such as hoops, ribs or grooves may form at the position with large thickness deviation. These defects directly affect the user's reprocessing and use, such as color printing color misalignment or uneven glue coating and wrinkling, which reduce or lose its use value. Therefore, the most critical quality issue in BOPP film production is how to improve and stabilize the film thickness accuracy. It is this film thickness accuracy that directly affects the use value of the film and determines the commercial value of the film.
[0004] Many of the online film thickness detectors used in domestic BOPP film manufacturing production lines are imported from abroad as a set with electrical control equipment. The data of the thickness gauge is often transmitted to the control equipment in a specific format. The profile thickness image output by the thickness gauge on the display is manually monitored, and then the replaced control equipment is adjusted based on experience. This manual monitoring and adjustment is not only inaccurate, but also unstable. Due to the lack of continuous and accurate monitoring of film thickness, the quality of film products is often affected.
[0005] Therefore, in order to solve the above problems, a film thickness acquisition device with AI autonomous learning graphics technology is proposed. Summary of the invention
[0006] The purpose of the present invention is to provide a film thickness acquisition device with AI autonomous learning graphics technology, which consists of two parts: hardware and software. The hardware part includes a mounting base plate. On both inner sides of the mounting base plate, a first mounting frame and a second mounting frame are respectively arranged. On both sides of the first mounting frame and the second mounting frame, a first rotating shaft and a second rotating shaft are respectively arranged. The first rotating shafts on both sides of the first mounting frame respectively penetrate through the mounting base plate and extend to the outside of the mounting base plate to be connected with a first rotating disk. The second rotating shafts on both sides of the second mounting frame respectively penetrate through the mounting base plate and extend to the outside of the mounting base plate to be connected with a second rotating disk. Inside the upper part of the first mounting frame, a unwinding roller is rotationally connected through a third rotating shaft. The third rotating shaft at the end of the unwinding roller penetrates through the first mounting frame and extends to the outside of the first mounting frame to be connected with a first rotating motor. Inside the upper part of the second mounting frame, a winding roller is rotationally connected through a fourth rotating shaft. The fourth rotating shaft at one end of the winding roller penetrates through the second mounting frame and extends to the outside of the second mounting frame to be connected with a second rotating motor. At the center position above the mounting base plate, a cushion plate is arranged. On both sides below the cushion plate, mounting plates are respectively arranged. The mounting plates are fixed on the mounting base plate through second fastening bolts. At the rear end of the mounting base plate, a rear support frame is arranged. At the center position below the rear support frame, an ultrasonic thickness gauge is arranged. Below the ultrasonic thickness gauge, a detection probe is arranged. On both sides below the rear support frame, two mounting vertical plates are respectively arranged. Between the two mounting vertical plates, a camera is adjustably arranged;
[0007] The software part includes a film thickness calculation module, a film thickness result generation module, a parameter adjustment module, an image extraction module, an image processing module, and a 3D modeling module. The film thickness calculation module is respectively connected with the ultrasonic thickness gauge and the film thickness calculation module. The film thickness calculation module is connected with the film thickness result generation module. The film thickness result generation module is connected with the parameter adjustment module. The image extraction module is respectively connected with the camera and the image processing module. The image processing module is connected with the 3D modeling module.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0009] The present invention combines software and hardware. The film thickness is detected through the hardware, and the film thickness is obtained through software calculation of the sound wave. The 3D model parameters generated by the image are adjusted according to the calculated film thickness, so as to obtain accurate film thickness data and improve the accuracy of film thickness acquisition.
[0010] By respectively loosening the first fastening bolts on both sides of the mounting base plate and rotating the first rotating disk and the second rotating disk, the present invention can facilitate changing the angles of the unwinding roller and the winding roller as needed.
[0011] By arranging the cushion plate, the mounting plates, and the second fastening bolts, and loosening the fastening bolts to remove the cushion plate, the height of the cushion plate can be adjusted according to the heights of the unwinding roller and the winding roller.
[0012] In the present invention, cameras are respectively arranged on both sides below the rear support frame, and the angles of the cameras can be adjusted, which is convenient for detecting the device from multiple angles, and then for generating visual images and facilitating 3D modeling.

At the center position above the mounting base plate 1, there is a cushion plate 12. On both sides below the cushion plate 12, there are respectively mounting plates 13. The mounting plates 13 are fixed on the mounting base plate 1 through fastening bolts two 14. At the rear end of the mounting base plate 1, there is a rear support frame 15.

[0020] As shown in the attached Figure 3 figure, the software part includes a film thickness calculation module, a film thickness result generation module, a parameter adjustment module, an image extraction module, an image processing module, and a 3D modeling module.

After the installation is completed, the detection probe 21 below the ultrasonic thickness gauge 20 emits ultrasonic waves. When the ultrasonic pulse reaches the material interface through the measured object, the pulse is reflected back to the probe. The thickness of the measured material is determined by accurately measuring the propagation time of the ultrasonic wave in the material, and the propagation time is sent to the film thickness calculation module. After the film thickness calculation module calculates the film thickness, it is transmitted to the film thickness result generation module. The data generated by the film thickness result generation module is transmitted to the parameter adjustment module.

After the image processing module processes it, it is sent to the 3D modeling module for modeling, and the parameter adjustment module adjusts the internal parameters of the 3D modeling module, thereby improving the accuracy of film thickness acquisition.
