[0002] During the production of electrolytic copper, the cathode plate can easily deform due to external forces or improper operation, affecting its verticality. Cathode plate verticality is closely related to the quality of the electrolytic copper; as cathode plate verticality increases, copper production quality declines. Currently, however, cathode plate verticality is typically measured visually. This method is highly subjective and inconsistent, resulting in low accuracy and efficiency. Furthermore, using specialized equipment for verticality testing is prohibitively expensive. Utility Model Content

[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0024] Please refer to Figure 1 , the embodiment of the utility model provides a cathode plate verticality detection system, including a suspension device, a verticality reference device and a photographing device;

[0025] The suspension device is located between the verticality reference device and the photographing device, and is used to suspend the cathode plate;

[0026] The verticality reference device includes a reference plate, the reference surface of the reference plate is perpendicular to the suspension surface of the suspension device, and a calibration line is provided on a side of the reference plate close to the suspension device;

[0027] The photographing device faces the suspension device and the reference plate.

[0028] From the above description, it can be seen that the beneficial effect of the present invention is that the verticality detection system sets the suspension device on which the cathode plate is suspended between the verticality reference device and the photographic device, and the photographic device can obtain an image that contains both the edge contour line of the cathode plate and the calibration line of the reference plate. By comparing the angle between the calibration line and the edge contour line of the cathode plate in the image, the verticality of the cathode plate is detected. The detection system improves the accuracy of the detection results and can realize batch detection of cathode plates with high detection efficiency; the system structure is simple and the production cost is low.

[0029] Furthermore, the calibration lines include a first group of parallel lines and a second group of parallel lines; the first group of parallel lines is arranged in the horizontal direction on the side of the reference plate close to the suspension device, and the second group of parallel lines is arranged in the vertical direction on the side of the reference plate close to the suspension device.

[0030] From the above description, it can be seen that two sets of parallel lines in the horizontal direction and the vertical direction are used to establish reference standards for the cathode plate in two different directions. The first set of parallel lines in the horizontal direction is used to correct the verticality of the hanging position of the cathode plate, and the second set of parallel lines in the vertical direction is used to detect the verticality of the cathode plate itself; the relative position of the cathode plate is limited by calibration lines in different directions, thereby improving the accuracy of the detection results.

[0031] Furthermore, the intersection of the first group of parallel lines and the second group of parallel lines is marked.

[0032] From the above description, it can be seen that in the process of measuring verticality by obtaining an image of the edge contour line of the cathode plate, the cathode plate and the photographic device may shake slightly due to changes in the external environment, causing distortion between the obtained image and the actual relative relationship. Therefore, an intersection mark is set to enable the photographic device to perform adaptive dynamic adjustment when there is slight shaking and calibrate the relative relationship.

[0033] Furthermore, the area surrounded by the first group of parallel lines and the second group of parallel lines is a determination area, and the determination area is larger than an area of ​​the suspension device for suspending a single cathode plate.

[0034] From the above description, it can be seen that the determination area must completely surround the cathode plate in order to ensure the positional relationship between the cathode plate and the calibration line and achieve the angle measurement of verticality.

[0035] Furthermore, it also includes a fill light device; the fill light device is arranged on a side of the suspension device away from the verticality reference device, and the irradiation area of ​​the fill light device coincides with the shooting area of ​​the camera device.

[0036] From the above description, it can be seen that the fill light device mainly provides sufficient light to ensure that the light changes in the detection environment are relatively uniform 24 hours a day, and avoid deviations in the detection effect caused by changes in light and shadow.

[0037] Furthermore, the reference plate is a dark opaque acrylic plate.

[0038] From the above description, it can be seen that if the reference plate is dark, the contrast between the reference plate color and the ambient color is greater, and it is easier to obtain the image edge contour of the cathode plate in the later image processing process, and the edge contour is clearer, ensuring the accuracy of the verticality detection result.

[0039] Furthermore, the photographing device is a CCD industrial camera.

[0040] As can be seen from the above description, since this inspection system is mainly used in production lines, its inspection environment is complex and has many interference factors. Therefore, a CCD (Charge Coupled Device) industrial camera with stronger anti-interference capabilities and more stable image transmission is selected.

[0041] Furthermore, the verticality reference device also includes a horizontal laser instrument, which is detachably arranged around the reference plate; the horizontal laser instrument is used to draw the calibration line.

[0042] From the above description, it can be seen that the calibration line is drawn with a horizontal laser to ensure the parallelism and verticality of the calibration line.

[0043] Furthermore, the verticality reference device and the photographing device are respectively arranged opposite to the cathode plate suspended by the suspension device, and the centers of the verticality reference device, the photographing device and the cathode plate suspended by the suspension device are all located on the same straight line.

[0044] From the above description, it can be seen that only when the relative positions of the reference plate, the photographing device and the cathode plate are aligned and located on the same straight line can the photographing device accurately capture the edge contour of the cathode plate. Otherwise, it is easy to cause edge contour acquisition errors, affecting the detection results.

[0045] Furthermore, it also includes an information processing device, which is connected to the photographing device; the information processing device is used to receive the image obtained by the photographing device, which has the edge contour line of the cathode plate and the calibration line of the reference plate, and calculate the verticality of the cathode plate based on the image.

[0046] As can be seen from the above description, the information processing device is used to realize accurate processing and calculation of information, and realize intelligentization and unification of verticality detection standards.

[0047] The utility model provides a cathode plate verticality detection system, which can be used for verticality detection of cathode plates of electrolytic copper and other similar flat plates, and has high accuracy of detection results, high detection efficiency and low production cost. The utility model is described below through specific embodiments:

[0048] Please refer to Figures 1 to 2 , the first embodiment of the present utility model is:

[0049] A cathode plate verticality detection system includes a suspension device 1, a verticality reference device 2 and a photographing device 3; the suspension device 1 is located between the verticality reference device 2 and the photographing device 3, and the suspension device 1 is used to suspend the cathode plate 4; the verticality reference device 2 includes a reference plate 21, the reference surface of the reference plate 21 is perpendicular to the suspension surface of the suspension device 1, and a calibration line 22 is provided on the side of the reference plate 21 close to the suspension device 1; the photographing device 3 faces the suspension device 1 and the reference plate 21.

[0050] It should be noted that a plurality of cathode plates 4 can be suspended on the suspension device 1 at the same time, the centers of the plurality of cathode plates 4 are all located on the same straight line, and the cathode plates 4 are parallel to each other.

[0051] In this embodiment, please refer to Figure 1The structure of the suspension device 1 is specifically as follows: the suspension device 1 includes two long rods 11 that are parallel to each other and arranged longitudinally, and a short rod 12 installed between the two long rods; the number of the short rods 12 is the same as the number of suspended cathode plates 4; after the cathode plate 4 is fixed to the middle of the short rods 12, the short rods 12 are installed between the long rods 11 to ensure that the cathode plate 4 is in a vertically suspended state.

[0052] Specifically, the verticality reference device 2 and the photographing device 3 are respectively arranged opposite to the cathode plate 4 suspended by the suspension device 1, and the centers of the verticality reference device 2, the photographing device 3 and the cathode plate 4 suspended by the suspension device 1 are all located on the same straight line.

[0053] It should be noted that when the photographing device 3 starts shooting, the center of the photographing device 3, the center of the side edge of the cathode plate 4, and the center of the determination area 23 of the reference plate 21 are located on the same straight line; at this time, the image accuracy obtained by the photographing device 3 is the best.

[0054] Specifically, the calibration line 22 includes a first group of parallel lines 221 and a second group of parallel lines 222; the first group of parallel lines 221 are arranged in the horizontal direction on the side of the reference plate 21 close to the suspension device 1, and the second group of parallel lines 222 are arranged in the vertical direction on the side of the reference plate 21 close to the suspension device 1.

[0055] The intersection of the first group of parallel lines 221 and the second group of parallel lines 222 is marked.

[0056] The area surrounded by the first group of parallel lines 221 and the second group of parallel lines 222 is a determination area 23 . The determination area 23 is larger than the area of ​​the suspension device 1 for suspending a single cathode plate 4 .

[0057] In this embodiment, each set of parallel lines includes only two calibration lines 22, meaning there are four calibration lines 22, with two calibration lines 22 provided horizontally and two vertically on the reference plate 21. The horizontal and vertical calibration lines 22 intersect to form intersections, and the area enclosed by these intersections is marked as a determination area 23. The intersections are the corners of the determination area and can be used to locate the field of view of the camera 3 and the reference plate 21. The identifiers can be marked with an Aruco code or a specific color.

[0058] In an optional embodiment, the reference plate 21 is a dark opaque acrylic plate.

[0059] In an optional embodiment, the photographing device 3 is a CCD industrial camera.

[0061] It should be noted that the centers of the photographing device 3 and the fill light device 5 are as close as possible so that the light source and the photographing device 5 are at the same center to avoid light deviation causing light and shadow deviation and image interference.

[0062] The verticality reference device 2 further includes a horizontal laser instrument 24 , which is detachably arranged around the reference plate 21 ; the horizontal laser instrument 24 is used to draw the calibration line 22 .

[0063] It should be noted that the calibration line 22 can also be drawn in a computer using the internal level calibration software and then directly printed on the reference plate 21 .

[0064] The cathode plate verticality detection system also includes an information processing device, which is connected to the photographing device 3; the information processing device is used to receive the image obtained by the photographing device 3 with the edge contour line of the cathode plate and the calibration line of the reference plate, and calculate the verticality of the cathode plate based on the image.

[0065] It should be noted that all edge contours of the cathode plate 4 can be tested for verticality. When hanging the cathode plate 4 , it is only necessary to select the side of the cathode plate 4 where the edge contour can be obtained to be hung toward the photographing device 3 .

[0066] The working principle of the cathode plate verticality detection system is as follows: draw calibration lines on the reference surface of the reference plate and print marks at the corner points, such as using a horizontal laser to draw the calibration lines, and at the same time set and fix the reference plate vertically; place the hanging device on the side of the reference plate close to the reference surface, and hang multiple cathode plates in batches, and the hanging surface of the hanging device is perpendicular to the reference surface of the reference plate; place the photographic device opposite to the hanging device and the reference plate, and adjust the shooting area of ​​the photographic device to include the judgment area on the reference plate; at the same time, set the fill light device below the photographic device, and adjust the irradiation area of ​​the fill light device to coincide with the shooting area of ​​the photographic device; the information processing device is connected to the photographic device, the information processing device sends instructions, the photographic device receives the instructions to obtain an image with the edge contour line of the cathode plate and the calibration line of the reference plate and returns the image to the information processing device, and the information processing device calculates the verticality of the cathode plate based on the image.

[0067] In summary, the present invention provides a cathode plate verticality detection system. The verticality detection system sets a suspension device on which the cathode plate is suspended between a verticality reference device and a photographing device. The photographing device can then obtain an image that includes both the edge contour line of the cathode plate and the calibration line of the reference plate. By comparing the angle between the calibration line and the edge contour line of the cathode plate in the image, the verticality of the cathode plate can be detected. This detection system improves the accuracy of the detection results and can realize batch detection of cathode plates.
