Abstract
Description
Technical Field
[0001] The present application relates to the technical field of detection equipment, and more specifically, to a double-sided CCD detection equipment. Background Art
[0002] CCD detection device refers to a detection device that uses a charge-coupled device (CCD) as a sensor. CCD is a semiconductor device that is usually used to convert light signals into electrical signals. In the detection device, CCD is usually used to capture light signals and then convert them into digital signals for analysis, processing or storage. In the manufacturing process of strip items, they need to be inspected to ensure that the products meet specifications and quality standards. By inspecting key parameters such as size, shape, surface defects, etc., problems in production can be discovered and corrected early to ensure product quality.
[0003] When the existing CCD detects strip-like objects, it is difficult to keep the strip-like objects under the CCD camera because the strip-like objects are easily offset on the conveyor roller when moving. If they are not under the CCD, the field of view of the CCD camera may not be able to fully cover the entire width or length of the strip-like objects, resulting in poor detection effect, which will cause information loss or blur in some areas and affect the accuracy of the detection results.

In this process, the conveyor roller is located on one side of the workbench, and the strip-like article to be inspected is sent to the inspection table, and the winding roller is used to wind up the inspected strip-like article.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0030] Reference Figure 1-Figure 5 , a double-sided CCD detection device, comprising a workbench 1, a detection box 3 is provided on the top of the workbench 1, and an anti-deflection component is provided inside the detection box 3;
[0031] The anti-deviation component includes a first annular traction belt 12, which is located on the top of the workbench 1. A second annular traction belt 14 is provided on the side of the workbench 1 away from the first annular traction belt 12. A fixed plate 17 is fixedly connected to the bottom of the second annular traction belt 14, and a slider 16 is fixedly connected to one end of the fixed plate 17.
[0032] By setting the anti-deviation component, the strip-shaped article can be prevented from being deviated during detection, the strip-shaped article can be prevented from deviating from the center of the CCD camera 9, the information of some areas can be prevented from being lost or blurred, and the accuracy of the detection result can be prevented from being affected.
[0033] Reference Figure 4-Figure 5 A slide groove is provided on the top of the workbench 1, and the second annular traction belt 14 is slidably connected to the slide groove. A connecting frame 11 is provided on the top of the workbench 1, and a motor 13 is provided on one side of the connecting frame 11. A threaded rod 15 is rotatably connected inside the connecting frame 11. The motor 13 is located on one side of the connecting frame 11, and the output end of the motor 13 is fixedly connected to the threaded rod 15. The slider 16 is threadedly connected to the threaded rod 15, and the slider 16 is slidably connected to the connecting frame 11.
[0034] The first annular traction belt 12 on one side fixes one end of the belt-like article, and the motor 13 can drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, it drives the slider 16 to slide and connect inside the connecting frame 11. When the slider 16 slides inside the connecting frame 11, it drives the fixed plate 17 to slide inside the slide groove of the workbench 1, and then drives the second annular traction belt 14 to limit the belt-like article to prevent the belt-like article from deviating during mobile detection.
[0035] The first annular traction belt 12 and the second annular traction belt 14 are electric conveyor belt structures of the technology, so in the process of winding up the belt-like article after detection, the first annular traction belt 12 and the second annular traction belt 14 move synchronously with the belt-like article. Therefore, the first annular traction belt 12 and the second annular traction belt 14 are in rolling friction with the edge of the belt-like article, so that the edge of the belt-like article is subjected to more even force distribution, reducing the possibility of damage to the belt-like article.
[0036] Reference Figure 4-Figure 5 An electric slide rail 7 is provided inside the detection box 3, one end of the electric slide rail 7 is slidably connected to a sliding plate, one side of the sliding plate is fixedly connected to a CCD camera 9, a placement plate 10 is provided below the CCD camera 9, and a detection table 8 is provided on the top of the workbench 1, and the detection table 8 is located below the CCD camera 9.
[0037] When the strip-shaped article moves above the inspection platform 8, the CCD camera 9 performs visual inspection on it, and the electric slide rail 7 drives the CCD camera 9 to move downward. By controlling the vertical position of the CCD camera 9, the distance between it and the strip-shaped article to be inspected can be adjusted, thereby achieving focal length adjustment. This ensures that the CCD camera 9 can capture the image of the strip-shaped article at the best focal length for accurate visual inspection.
[0038] Reference Figure 3-Figure 4 , frames are provided on both sides of the detection box 3, cylinders 18 are provided on the tops of the two frames, and pressing rollers 6 are provided on the bottoms of the two cylinders 18.
[0039] When the strip-like article moves, the cylinder 18 drives the pinch roller 6 to move downward and come into contact with the strip-like article. Specifically, the pinch roller 6 usually applies a small pressure and provides a slight friction force, thereby ensuring that the strip-like article maintains a stable position and direction during the detection process. This can prevent the strip-like article from shaking, deviating or sliding during movement, thereby ensuring the accuracy and reliability of the detection results.
[0040] Reference Figure 1 A controller 4 is provided on one side of the workbench 1, and the controller 4 is electrically connected to the CCD camera 9. A conveying roller 2 and a winding roller 5 are provided on both sides of the workbench 1, and the number of the conveying roller 2 and the winding roller 5 are both two.
[0041] The conveyor roller 2 is used to convey the strip-like article from one position to another. In this process, the conveyor roller 2 is located on one side of the workbench 1, and conveys the strip-like article to be inspected to the inspection table 8. The winding roller 5 is used to wind up the inspected strip-like article.
[0042] Working principle: When in use, the conveyor roller 2 is used to convey the strip-like articles from one position to another. In this process, the conveyor roller 2 is located on one side of the workbench 1, and the strip-like articles to be inspected are sent to the inspection table 8. At this time, the motor 13 can drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, it drives the slider 16 to slide and connect inside the connecting frame 11. When the slider 16 slides inside the connecting frame 11, it drives the fixed plate 17 to slide inside the slide groove of the workbench 1, and then drives the second annular traction belt 14 to limit the strip-like articles to avoid the strip-like articles entering the inspection table 8 from being offset. When the strip-like articles move above the inspection table 8, the CCD camera 9 performs visual inspection on them. After the inspection is completed, the winding roller 5 is used to wind up the inspected strip-like articles.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
