A visual detection-based intelligent deviation correction system and method

Abstract

This invention relates to the field of coil processing equipment technology, and particularly to an intelligent web-alignment system and method based on vision inspection. The technical solution includes limiters, a base shell, vision inspection modules, and an automatic web-alignment component. An operating platform is mounted on the top of the base shell, and two sets of limiters are equally spaced on the top of the operating platform. Vision inspection modules are mounted on both sides of the top of the operating platform. By installing the automatic web-alignment component and auxiliary web-alignment component on the top of the operating platform, and using the two sets of vision inspection modules to detect the position of the coil on both the infeed and outfeed sides, the degree of coil offset is determined. The automatic web-alignment component and auxiliary web-alignment component work together to apply a certain horizontal thrust to the coil, ensuring that the coil remains in the set position after output. This facilitates subsequent cutting of the coil, ensuring that the dimensions of the coil meet processing requirements, thereby improving the quality of the composite metal coil leaving the factory.

Description

Technical Field

[0001] This invention relates to the field of roll material processing equipment technology, specifically to an intelligent deviation correction system and method based on vision detection. Background Technology

[0002] Among industrial production materials, composite metal coils have superior physical properties, and therefore are widely used in industrial production. During the industrial production process, composite metal coils need to be processed and inspected. To ensure that the coils meet the customer's size requirements when they leave the factory, some coils need to be cut off. However, the coils will deviate to a certain extent during processing, which will affect the dimensional accuracy of the processed products. Therefore, the coils need to be corrected by visual inspection and servo control systems.

[0003] In the use of existing roll material correction devices, the roll material requires manual assistance to find its edges. Furthermore, the contact area between the correction structure and the edge of the roll material is relatively large, while the edge of the roll material is usually a thin sheet with a small thickness. Conventional correction structures are prone to causing the roll material to curl during the conveying process, which can lead to damage to the roll material and reduce the detection and correction effect. In addition, for thicker roll materials, deviation during the roll material processing will result in a low yield rate after the roll material is processed.

[0004] Therefore, we propose a vision-based intelligent correction system and method to address the existing problems. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent deviation correction system and method based on visual detection to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent deviation correction system and method based on visual inspection, comprising limiters, a base, visual inspection modules, and an automatic deviation correction component. An operating platform is mounted on the top of the base. Two sets of limiters are equally spaced on the top of the operating platform. Visual inspection modules are mounted on both sides of the top of the operating platform, with one set of visual inspection modules positioned between the two sets of limiters. An auxiliary deviation correction component is mounted on one side of each limiter, and an automatic deviation correction component is mounted on one side of the auxiliary deviation correction component. A mounting base is provided within the automatic deviation correction component, and servo motors are mounted on both sides of the mounting base. A lead screw is installed at the output end of the servo motor. A slide is installed on the outside of the lead screw, and a limit roller is installed on the top of the slide. A guide rail is installed on the top of the mounting base, and a partition is installed at the center of the top of the mounting base. A limit seat is provided inside the auxiliary correction assembly. A threaded rod is installed inside the limit seat. One end of the threaded rod extends to one side of the limit seat and is equipped with a drive motor. A lower pressure plate is installed on the top of the threaded rod, and the bottom two sides of the lower pressure plate are engaged with the limit seat. An upper pressure plate is installed on the top of the lower pressure plate by four sets of bolts. Two sets of limit rods are installed on one side of the lower pressure plate, and a velvet cloth is installed on the top of the lower pressure plate and the bottom of the upper pressure plate.

[0007] Preferably, a protective shell is installed on the top outer side of the bottom shell, and a control screen is installed on one side of the protective shell.

[0008] Preferably, the limiter has two sets of support rollers installed inside, and the height of the support roller near the top is adjustable.

[0009] Preferably, the visual inspection module consists of a drive cylinder and an inspection camera, and the drive cylinder can drive the inspection camera to adjust its height.

[0010] Preferably, four sets of limiting buckles are installed on the top outer side of the guide rail, and the top of the limiting buckles is fixedly connected to the bottom of the slide block.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This invention features an automatic and auxiliary correction component installed on the top of the operating table. Two sets of vision detection modules detect the position of the coil on both the infeed and outfeed sides to determine the degree of deviation. The automatic and auxiliary correction components apply a horizontal thrust to the coil, ensuring it remains in the set position after output. This facilitates subsequent cutting of the coil, ensuring its dimensions meet processing requirements and improving the quality of the composite metal coil. Furthermore, the correction amplitude can be automatically adjusted according to different coil specifications to guarantee the correction effect. Attached Figure Description

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention proposes an intelligent deviation correction system and method based on visual inspection, comprising a limiter 2, a base shell 4, a visual inspection module 7, and an automatic deviation correction component 8. An operating platform 5 is mounted on the top of the base shell 4. Two sets of limiters 2 are equally spaced on the top of the operating platform 5. Visual inspection modules 7 are mounted on both sides of the top of the operating platform 5, with one set of visual inspection modules 7 positioned between the two sets of limiters 2. An auxiliary deviation correction component 9 is mounted on one side of each limiter 2, and an automatic deviation correction component 8 is mounted on one side of the auxiliary deviation correction component 9. A mounting base 803 is provided inside the automatic deviation correction component 8. Servo motors 801 are mounted on both sides of the mounting base 803, and a lead screw 805 is mounted on the output end of each servo motor 801. A lead screw 805 is mounted on the outer side of the lead screw 805. A slide block 802 is provided, and a limit roller 808 is installed on the top of the slide block 802. A guide rail 807 is installed on the top of the mounting base 803, and a partition plate 804 is installed at the center of the top of the mounting base 803. A limit seat 901 is provided inside the auxiliary correction component 9. A threaded rod 904 is installed inside the limit seat 901. One end of the threaded rod 904 extends to one side of the limit seat 901 and a drive motor 905 is installed thereon. A lower pressure plate 902 is installed on the top of the threaded rod 904, and the bottom two sides of the lower pressure plate 902 are engaged with the limit seat 901. An upper pressure plate 907 is installed on the top of the lower pressure plate 902 by four sets of bolts. Two sets of limit rods 906 are installed on one side of the lower pressure plate 902, and a velvet cloth 903 is installed on the top of the lower pressure plate 902 and the bottom of the upper pressure plate 907.

[0021] After being limited by the limiter 2, the roll material moves stably inside the device. The first set of vision detection modules 7 judges the magnitude of the roll material deviation and then feeds back an electrical signal to the automatic correction component 8. After the auxiliary correction component 9 performs the first correction, the automatic correction component 8 automatically performs the second correction on the roll material, so that the roll material can be kept in the center position for output. Then, the vision detection module 7 at the tail end performs a second visual inspection on the roll material, which can judge the effect of the correction and facilitate the subsequent cutting of the roll material. By installing a velour cloth 903 inside the device, the outer surface of the roll material can be prevented from being damaged during high-speed movement.

[0022] Furthermore, a protective shell 1 is installed on the top outer side of the bottom shell 4, and a control panel 6 is installed on one side of the protective shell 1.

[0023] The protective shell 1 ensures the safety of the device during operation and prevents the high-speed moving roll from causing injury to the staff. The control panel 6 facilitates the control of the device and displays the device's test results and test data.

[0024] Furthermore, the limiter 2 has two sets of support rollers 3 installed inside, and the height of the support roller 3 near the top is adjustable.

[0025] The support roller 3 can be connected to an external motor to rotate, and the roll material can be clamped by two sets of support rollers 3, thus driving the roll material to move at high speed.

[0026] Furthermore, the visual inspection module 7 consists of a drive cylinder and an inspection camera, and the drive cylinder can drive the inspection camera to adjust its height.

[0027] The extension and retraction of the drive cylinder causes the detection camera to move vertically, thereby adjusting the detection range of the detection camera for the roll material. The detection camera can perform high-precision offset detection of the roll material, which facilitates the control of the automatic web correction component 8 to perform web correction processing on the roll material.

[0028] Furthermore, four sets of limit buckles 806 are installed on the top outer side of the guide rail 807, and the top of the limit buckles 806 is fixedly connected to the bottom of the slide block 802.

[0029] The limit buckle 806 can restrict the slide 802 to the top of the guide rail 807, thereby ensuring the stability of the slide 802 when moving horizontally.

[0030] The working principle of the vision-based intelligent web-correction system and method based on Embodiment 1 is as follows: After the upper and lower limits of the roll material are set by two sets of limiters 2, the roll material moves stably inside the device. When the roll material moves to the lower part of the first set of vision detection modules 7, the vision detection module 7 detects the offset of the roll material. After the roll material is corrected for the first time by the auxiliary web-correction component 9, the offset signal fed back by the first set of vision detection modules 7 controls the automatic web-correction component 8. The automatic web-correction component 8 performs fine-grained position correction according to the offset signal, so that the roll material below moves to the set position. After correction, the roll material continues to move to the lower part of the second set of vision detection modules 7, so that the device automatically judges the web-correction effect and feeds it back to the automatic web-correction component 8 for adjustment. At the same time, the web-correction result is displayed on the control screen 6 and output from the opening at the tail end, completing the automated web-correction process of the composite metal roll material.

[0031] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
