[0032] The technical solutions in the embodiments of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application.

[0033] It should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including a..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0034] The present application embodiment provides a steel strapping recycling system, combined with Figure 2 The three-dimensional structural diagram of the steel strapping recovery system is shown, and Figure 3 , Figure 4 As shown in the front view and top view, the steel strap recycling system includes a strapping device 21, a strapping sorting and shearing device 22 and a steel strap welding device 23, wherein:

[0035] The debundling device 21 can be used to debundle steel coils to obtain steel straps. In the embodiment of the present application, high-value parts and low-value parts of the steel straps can be classified and sheared for recycling.

[0036] In addition, combined Figure 2 As shown, the debundling device 21 may include a debundling head 211 and an industrial robot 212. The industrial robot 212 can be used to control the debundling head 211 to debundle the steel coils to obtain steel straps. For example, in actual applications, an automatic control program can be usually set in the industrial robot 212, or the industrial robot 212 can be manually operated to control the debundling head 211 to debundle the steel coils to obtain steel straps.

[0037] Of course, after obtaining the steel strap, the industrial robot 212 can also be used to control the debaling head 211 to transfer the steel strap to the strap sorting and shearing device 22, thereby facilitating the sorting and shearing device 22 to perform its function.

[0038] Among them, the strap classification and shearing device 22 can be used to classify and shear the high-value parts and low-value parts in the steel strap. For example, the strap classification and shearing device 22 can shear the junction (or near the junction) between the high-value part and the low-value part, thereby achieving classification and shearing of the two.

[0039] It should be emphasized that in the embodiment of the present application, after the steel coils are unbundled to obtain the steel straps, the steel straps are not directly recycled, but the high-value parts and low-value parts of the steel straps are further identified and then classified for recycling. Therefore, in the embodiment of the present application, how to identify the high-value parts and low-value parts of the steel straps is crucial for the classified cutting and classified recycling of the two. Among them, how to identify the high-value parts and low-value parts of the steel straps will be explained in detail later.

[0040] In addition, the high-value portion specifically refers to a portion of the steel strapping having a relatively high value, and the low-value portion specifically refers to a portion of the steel strapping excluding the high-value portion.

[0041] Regarding the steel strap welding device 23 in the steel strap recycling system in the embodiment of the present application, the steel strap welding device 23 can be used to weld the multiple high-value parts obtained by the strap classification and shearing device 22 into new steel straps. For example, after the strap classification and shearing device 22 classifies and shears the high-value parts and low-value parts in the steel strap, the high-value parts will be transmitted to the steel strap welding device 23, so that the steel strap welding device 23 can re-weld these high-value parts to obtain the new steel strap. Obviously, the new steel strap is composed of the high-value parts in the steel strap, so it has a high recycling value.

[0042] The steel strap recycling system provided in the embodiment of the present application is adopted, and the steel strap recycling system includes: a debundling device 21, a strap sorting and shearing device 22 and a steel strap welding device 23. The debundling device 21 can be used to debundle the steel coils to obtain steel straps. The strap sorting and shearing device 22 can be used to sort and shear the high-value parts and low-value parts in the steel straps. The steel strap welding device 23 can be used to weld the multiple high-value parts obtained by sorting and shearing the strap sorting and shearing device 22 into new steel straps. Obviously, the new steel straps are all composed of the high-value parts in the steel straps, so they have a higher recycling and reuse value. Therefore, the problems in the prior art can be solved by the steel strap recycling system.

[0043] After the steel strap welding device 23 welds multiple high-value parts into new steel straps, in order to facilitate the storage of the new steel straps, it can be further combined with Figure 2As shown, the steel strap recycling system may further include a curling and recycling device 24, wherein the curling and recycling device 24 can be used to curl and recycle the new steel strap. After the steel strap welding device 23 welds multiple high-value parts into new steel straps, the new steel straps can be transferred to the curling and recycling device 24, so that the new steel straps in strip form can be curled and recycled by the curling and recycling device 24, thereby facilitating their management.

[0044] In practical applications, a loop 231 can usually be provided in the steel strap welding device 23, and the loop 231 can be used to store the new steel strap. For example, after the steel strap welding device 23 welds multiple high-value parts into new steel straps, the new steel strap can be stored in the loop 231 first, and then the new steel strap can be transmitted to the curling and recovery device 24 through the loop 231, so that the curling and recovery device 24 can curl and recover the new steel strap.

[0045] Here, the strap classification and shearing device 22 in the steel strap recycling system in the embodiment of the present application can be further explained. In actual applications, the strap classification and shearing device 22 can specifically include a value recognition module, a classification and shearing module, a low-value part recovery module and a high-value part transmission module, wherein: the value recognition module is used to identify the high-value parts and low-value parts in the steel strap; the classification and shearing module is used to classify and shear the high-value parts and low-value parts in the steel strap according to the recognition result of the value recognition module; the low-value part recovery module is used to recycle the low-value parts obtained by the classification and shearing module; the high-value part transmission module is used to transmit the high-value parts obtained by the classification and shearing module to the steel strap welding device 23, so that the steel strap welding device 23 can realize its own function.

[0046] That is to say, in the embodiment of the present application, it is necessary to first use the value recognition module to identify the high-value parts and low-value parts in the steel strapping, which is also a prerequisite for the subsequent classification and shearing module to perform classification and shearing. For example, the classification and shearing module shears the junction between the high-value parts and the low-value parts in the steel strapping according to the recognition result of the value recognition module, thereby realizing the classification and shearing of the two, and finally realizing the separate recycling of the two through other modules. Therefore, it is necessary here to explain in detail how the value recognition module identifies the high-value parts and low-value parts in the steel strapping.

[0047] In practical applications, the value of steel strapping is usually reflected in whether there are deterioration features such as scratches, rust, corrosion marks, rolling deformation marks, etc. on the surface of the steel strapping, as well as the thickness of the steel strapping. For example, when the thickness of a certain part of the steel strapping is large, it means that there may be nodules in this part, which leads to a lower value of this part, and therefore it is more likely to be a low-value part; when there are deterioration features on a certain part of the surface of the steel strapping, or when the deterioration features of this part are more and more obvious, it will also affect the value of this part, making it more likely to be a low-value part. On the contrary, if there are no deterioration features on a certain part of the surface of the steel strapping, or the deterioration features of this part are not obvious, it means that this part is more likely to be a high-value part. Therefore, in practical applications, the value recognition module can identify high-value parts and low-value parts in steel strapping in a variety of ways, and several of them can be listed here for illustration.

[0048] Among them, the first method is to identify whether the detected part is a high-value part based on the thickness of the detected part in the steel strap (specifically, the actual thickness of the detected part). Specifically, for example, a side image of the detected part can be collected, and then the actual thickness of the detected part can be identified through the side image, and the actual thickness is further compared with the reference thickness to identify whether the detected part is a high-value part. If the actual thickness of the detected part is greater than the reference thickness, it means that there may be nodules in the detected part, so it can be determined that the detected part is a low-value part. On the contrary, if the actual thickness is less than or equal to the reference thickness, it means that there are no nodules in the detected part, so it can be determined that the detected part is a high-value part.

[0049] Among them, the size of the reference thickness can usually be set according to actual conditions, for example, the size of the reference thickness can be determined according to the type and model of the steel strap; in addition, the detected part can be any part of the steel strap, for example, when the steel strap is driven to pass through the value recognition module at a constant speed, the value recognition module can identify the part close to itself, so the part of the steel strap close to the value recognition module can be used as the detected part, and then identified by the value recognition module.

[0050] In addition, in order to accurately identify the actual thickness of the detected part, a reference datum can be set at a side position close to the detected part. For example, the reference datum can be a ruler or a reference object with a set height. In this way, in the side image of the detected part obtained, the thickness of the detected part in the side image can be compared with the reference datum, thereby accurately determining the actual thickness of the detected part.

[0051] Here, the actual thickness is identified by collecting the side image of the detected part of the steel strap, and then whether the detected part is a high-value steel strap is identified. In actual applications, the actual thickness of the detected part can usually be determined by sensors or other means to further identify whether the detected part is a high-value part. This is not limited here.

[0052] The second method is to identify whether the detected part is a high-value part based on the degradation characteristics of the surface of the detected part in the steel strap. For example, in a scenario where the requirements for working conditions are relatively high, if the surface of the detected part has degradation characteristics, it means that it is a low-value part. On the contrary, if the surface of the detected part has no degradation characteristics, it means that it is a high-value part. Therefore, the surface image of the detected part can be collected, and then the surface image can be analyzed to identify whether the surface of the detected part has degradation characteristics such as scratches, rust, corrosion marks, rolling deformation marks, etc., and then determine whether the detected part is a high-value part. At this time, if there are degradation characteristics, it means that the detected part is a low-value part. On the contrary, if there are no degradation characteristics, it means that the detected part is a high-value part.

[0053] Of course, in the scenario where the working condition standard requirements are relatively low, if there is a certain amount or a small amount of degradation characteristics on the surface of the inspected part, it also has a relatively high recycling value. In this scenario, if there is a small amount of degradation characteristics on the surface of the inspected part of the steel strap, it can also be determined as a high-value part. Only when there are a large number of degradation characteristics will it be determined as a low-value part.

[0054] Specifically, the impact area of ​​the degradation feature can be determined first, and the proportion of the impact area in the total area of ​​the detected part can be further calculated. If the proportion is less than a preset threshold, it means that there are only a small number of degradation features on the surface of the detected part, and the impact of these small number of degradation features on the detected part is relatively small. Therefore, the detected part can be determined as a high-value part. Conversely, if the proportion is greater than or equal to the preset threshold, it means that there are a large number of degradation features on the surface of the detected part, and the detected part can be determined as a low-value part.

[0055] Among them, the affected area of ​​the degradation characteristics and the total area of ​​the detected part can be determined in the following ways. For example, a surface image of the detected part can be collected, and then the surface image can be used to determine the width and length of the detected part. Since the surface of the detected part can be approximated as a rectangle, the width and length of the detected part can be used to calculate the total area of ​​the steel strap.

[0056] For the affected area of ​​the degradation feature, the surface image of the detected part can be analyzed to select a target preset figure with a suitable shape and size from multiple preset figures, and the area of ​​the target preset figure is calculated as the affected area of ​​the degradation feature. Among them, the preset figure can usually be a rectangular, square, circular, elliptical and other offset figures to facilitate the calculation of its area. The target preset figure is specifically a preset figure whose size can just cover each degradation feature. For example, in the surface image, various preset figures of different sizes can be tried separately to determine whether they can just cover each degradation feature, and then finally select the target preset figure, and then calculate the area of ​​the target preset figure as the affected area of ​​the degradation feature. At this time, after obtaining the affected area of ​​the degradation feature, its proportion in the total area of ​​the detected part can be further calculated.

[0057] The third method can be, for example, to combine the actual thickness of the detected part in the steel strap and the degradation characteristics of the surface of the detected part in the steel strap to comprehensively identify whether the detected part is a high-value part. Specifically, for example, the actual thickness of the detected part can be converted into a corresponding thickness evaluation value, and the degradation characteristics of the surface of the detected part can be converted into a degradation characteristic evaluation value, and then the thickness evaluation value and the degradation characteristic evaluation value can be used to determine whether the detected part is a high-value part. For example, the comprehensive evaluation value can be determined based on the thickness evaluation value and the degradation characteristic evaluation value. Specifically, the thickness evaluation value and the degradation characteristic evaluation value can be substituted into Formula 1 shown below to calculate the comprehensive evaluation value:

[0058] P=a×f(D)+b×F(s) Formula 1

[0059] In Formula 1, f(D) is the thickness evaluation value, and the size of f(D) is usually negatively correlated with the actual thickness of the detected part; F(s) is the degradation feature evaluation value, and the size of F(s) is usually negatively correlated with the affected area of ​​the degradation feature; a and b are weights respectively; and P is the comprehensive evaluation value.

[0060] After obtaining the comprehensive evaluation value, the comprehensive evaluation value can be compared with the second threshold. If the comprehensive evaluation value is greater than the second threshold, it can be determined that the detected part is a high-value part. Otherwise, if the comprehensive evaluation value is less than or equal to the second threshold, it can be determined that the detected part is a low-value part.

[0061] In practical applications, the thickness assessment value f(D) can usually be determined in the following manner. For example, the actual thickness D of the detected part can be determined first (for the specific method of determining the actual thickness D, refer to the content mentioned in the first method above), and then the actual thickness D is substituted into the thickness assessment value calculation model to calculate the thickness assessment value f(D) corresponding to the actual thickness. The thickness assessment value calculation model can be, for example, a linear function of one variable, such as f(D) = k × D + b, where k and b are constants, and k is greater than 0. In practical applications, the specific values ​​of k and b can be obtained through relevant tests. In this way, after obtaining the actual thickness D of the detected part, f(D) = k × D + b can be substituted to calculate the thickness assessment value f(D) corresponding to the actual thickness D.

[0062] The degradation feature evaluation value F(s) can usually be determined in the following manner. For example, the influence area s of the degradation feature on the surface of the detected part can be determined first, wherein the influence area s of the degradation feature can refer to the content mentioned in the second method above; after obtaining the influence area s of the degradation feature, the influence area s of the degradation feature can be further substituted into the degradation feature evaluation value calculation model, thereby calculating the corresponding degradation feature evaluation value F(s). The degradation feature evaluation value calculation model can be, for example, F(s) = mn × s 2 , where m and n are both constants greater than 0. In practical applications, the specific values ​​of m and n can be obtained through relevant tests. After obtaining the affected area s of the degradation feature, it can be substituted into the degradation feature evaluation value calculation model to calculate the corresponding degradation feature evaluation value F(s).

[0063] After the thickness evaluation value f(D) and the degradation characteristic evaluation value F(s) are respectively calculated in the above manner, the f(D) and F(s) can be substituted into the above formula 1 to calculate the comprehensive evaluation value.
