Description

Technical Field

[0001] This utility model relates to the field of precision machining of aluminum plates and strips, and in particular to a surface scanning system for ingots. Background Technology

[0002] The purpose of milling ingots is to prepare for subsequent processing (such as rolling into coils). During milling, it's necessary to find the lowest point on the ingot surface as a reference for determining parameters such as the milling depth. Currently, the industry standard is to use a laser scanner to scan the center line of the ingot surface. The lowest point is found by scanning the center line to determine the milling reference. However, ingot surfaces are not flat, and the lowest point may not lie on the center line. Existing methods only scan the center line to determine the lowest point, leading to inaccurate identification and failing to reflect the true lowest point across the entire ingot surface.

[0003] Therefore, the laser line scanning method used in related technologies (scanning only the center line) cannot comprehensively obtain the surface height information of the ingot, thus failing to accurately detect the lowest point of the entire ingot surface. Milling based on this inaccurate lowest point as a reference will result in incomplete milling of the segregation layer, which will affect the quality of the ingot. When the ingot is rolled into coils, inaccurate milling issues such as incomplete segregation layer milling will lead to defects in the coils, resulting in product quality defects. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an ingot surface scanning system that can comprehensively acquire surface height information of the ingot, thereby accurately detecting the lowest point of the entire ingot surface.

Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0032] The ingot surface scanning system provided in this embodiment of the utility model, by setting up a 3D camera device, acquires image information of the ingot in real time during the ingot surface inspection process, comprehensively obtains the surface height information of the ingot, and thus accurately detects the lowest point of the entire ingot surface. This avoids the problem in related technologies where the use of a laser scanner to scan the center line of the ingot surface leads to the inability to accurately detect the lowest point of the entire ingot surface. This is beneficial for the milling machine to perform precise milling of the ingot, and thus helps to improve the quality of the finished product rolled into coils.

[0033] The ingot surface scanning system provided in the embodiments of this utility model will be described exemplarily below with reference to the accompanying drawings.

[0034] Figure 1 This is a schematic diagram of the structure of an ingot surface scanning system provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of another ingot surface scanning system provided in an embodiment of the present invention. Figure 3 This is a structural block diagram of a signal transmission system in an ingot surface scanning system provided as an embodiment of the present invention. It is understood that... Figure 1 and Figure 2 This is a schematic diagram of the ingot surface scanning system obtained from different perspectives.

[0035] like Figure 1 and Figure 3 As shown, the ingot surface scanning system includes: a camera bracket 10, a crossbeam 11, a 3D camera device 12, a guide rail 13, and an image processing device 14; the two ends of the crossbeam 11 are slidably connected to the guide rail 13, and the camera bracket 10 is fixed on the crossbeam 11; the 3D camera device 12 is mounted on the camera bracket 10; the crossbeam 11 is located above the roller conveyor 15, on which an ingot 16 is transported, the crossbeam 11 moves along the direction of the roller conveyor 15, and the 3D camera device 12 is used to acquire image information of the ingot 16 and transmit the image information to the image processing device 14.

[0036] The crossbeam 11 slides along the guide rail, causing the camera bracket 10 to slide along with it. The 3D camera device 12 mounted on the camera bracket 10 moves accordingly. During the movement of the 3D camera device 12, it can collect image information of the ingot 16 on the roller conveyor 15. For example, when the ingot 16 transported on the roller conveyor 15 reaches the target position (the target position can be understood as the ingot 16 being close to the crossbeam 11), the roller conveyor 15 can be controlled to pause transport, and the ingot 16 at the target position is stationary. At this time, the crossbeam 11 can be controlled to slide along the guide rail 13, thereby enabling the 3D camera device 12 to fully collect image information of the ingot 16 as it passes by.

[0037] Specifically, in this embodiment of the invention, a 3D camera device 12 is used to collect surface information of the ingot 16 in real time. This includes, but is not limited to, height data. The image information is transmitted to an image processing device 14, such as an image processing computer. The image processing computer's image software processes and analyzes the image of the ingot 16 in real time to obtain detection results, generating a complete surface morphology heat map. This heat map allows for viewing the height distribution of the ingot 16, thus facilitating accurate identification of the lowest point on the entire surface of the ingot 16. Subsequently, the image processing device 14 transmits the detection results to a milling machine. The milling machine performs milling, and because the lowest point of the ingot 16 can be accurately identified from the detection results, precise milling is achieved, improving the quality of the finished product.

[0038] Therefore, the ingot surface scanning system provided by this utility model, by setting up a 3D camera device, can collect image information of the ingot in real time during the ingot surface inspection process, comprehensively obtain the surface height information of the ingot, and thus accurately detect the lowest point of the entire ingot surface. This avoids the problem in related technologies where the use of a laser scanner to scan the center line of the ingot surface leads to the inability to accurately detect the lowest point of the entire ingot surface. This is beneficial for the milling machine to perform precise milling of the ingot, and thus helps to improve the quality of the finished product rolled into coils.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the camera bracket 10 includes an integrated first side plate 101, a second side plate 102, and a top plate 103, and the camera bracket 10 has a U-shaped structure.

[0040] The first side plate 101 and the second side plate 102 are fixedly connected to the side wall of the crossbeam 11, and the top plate 103 is arranged parallel to the crossbeam 11;

[0041] The 3D camera device 12 is located on the side wall of the top plate 103.

[0042] Specifically, by fixing the first side plate 101 and the second side plate 102 to the crossbeam 11, the entire camera bracket 10 can be fixedly mounted on the crossbeam 11. The 3D camera device 12 is positioned on the side wall of the top plate 103, ensuring that the ingot 16 falls precisely into the information acquisition range of the 3D camera device 12 as it passes the ingot 16.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, a plurality of 3D camera devices 12 are mounted on the camera bracket 10, and the adjacent 3D cameras are spaced apart by a preset distance.

[0044] Specifically, by setting up multiple 3D camera devices 12 and stitching together the images acquired by the multiple 3D camera devices 12, the field of view is increased while ensuring detection accuracy, and ultra-wide full-width detection is achieved, which is conducive to improving the accuracy of surface information acquisition of ingot 16.

[0045] For example, three 3D camera devices 12 are provided in the figure, and the interval between adjacent 3D cameras is preset. In some embodiments, the number of 3D camera devices 12 may be set according to the length of the crossbeam 11 and the size of the ingot 16, but this embodiment of the present invention does not specifically limit this.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the 3D camera device 12 includes a housing 121 and a 3D camera body 122 located within the housing 121;

[0047] The housing 121 is provided with an opening 125, which is oriented toward the roller conveyor 15.

[0048] The housing 121 protects the 3D camera body 122. The housing 121 has an opening 125 to enable the 3D camera body 122 to acquire surface information of the ingot 16, thereby collecting image information of the ingot 16.

[0049] In some embodiments, combined with Figures 1 to 3 The 3D camera body 122 includes an image sensor 123 and a data processing unit 124. The image sensor 123 converts the acquired light signal into an electrical signal and transmits it to the data processing unit 124. The data processing unit 124 is communicatively connected to the image processing device 14.

[0050] Specifically, the image sensor 123 converts the acquired optical signal data into electrical signal data, and then the data processing unit 124 processes the raw data acquired by the image sensor 123, such as image correction, and outputs a 3D image to the image processing device 14.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the guide rail 13 includes a first guide rail 131 and a second guide rail 132 arranged in parallel, and the crossbeam 11 is located between the first guide rail 131 and the second guide rail 132. Therefore, by setting the first guide rail 131 and the second guide rail 132, it is beneficial to ensure the sliding stability of the crossbeam 11.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the ingot surface scanning system further includes:

[0053] A linear motor 18, wherein the primary winding 181 of the linear motor 18 is mounted on the crossbeam 11, and the secondary winding 182 of the linear motor 18 is mounted on the guide rail.

[0054] Specifically, the linear motor 18 can directly generate linear motion without the need for an intermediate transmission mechanism. The primary motor 181, i.e., the mover, of the linear motor 18 is mounted on the crossbeam 11, and the secondary motor 182, i.e., the stator, is mounted on the guide rail 13. When the linear motor 18 is energized, an electromagnetic force is generated between the primary motor 181 and the secondary motor 182, which pushes the crossbeam 11 to move along the guide rail 13.

[0055] The above-mentioned method of using a linear motor 18 to drive the crossbeam 11 to move along the guide rail 13 has advantages such as fast response speed, high precision, smooth movement and no mechanical wear.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the ingot surface scanning system further includes:

[0057] The 3D camera device 12 is fixed to the camera bracket 10 via the fixing plate 17.

[0058] In this embodiment of the utility model, the fixing plate 17 is fixed to the camera bracket 10, specifically, the fixing plate 17 is fixed to the side wall of the top plate 103, and then the 3D camera device 12 is fixed to the fixing plate 17. Exemplarily, the fixing plate 17 is provided with a buckle, which can secure the fixing plate 17 to the side wall of the top plate 103. Then, for example, screws can be used to fix the housing 121 of the 3D camera device 12 to the fixing plate 17, which helps to improve the stability of the 3D camera device 12.

[0059] It should be noted that the ingot surface scanning system also includes other structures, such as support structures for supporting guide rails, which will not be described in detail here.

[0060] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0061] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
