Description

Technical Field

[0001] The present invention relates to the field of copper-clad steel production, and more particularly, to an efficient copper-clad steel device and an efficient pretreatment method for copper-clad steel. Background Art

[0002] In the production process of copper-clad steel, the pretreatment efficiency of the steel strip is a key factor restricting the overall production efficiency. If the pretreatment efficiency is too low, it will directly lead to low overall production efficiency. However, if the pretreatment speed is blindly increased, it is difficult to ensure the pretreatment effect. If the pretreatment does not meet the standards, it is very easy to affect the quality of the copper layer.

[0003] In view of this, the present application is specifically proposed. Summary of the Invention

[0004] The first object of the present invention is to provide an efficient copper-clad steel device, which can effectively monitor the pretreatment speed. Under the condition of ensuring the pretreatment quality, the pretreatment speed can be controlled within a faster and more reasonable range, taking into account both the treatment quality and treatment efficiency, which has positive significance for ensuring product quality and improving production efficiency.

[0005] The second object of the present invention is to provide an efficient pretreatment method for copper-clad steel, which can effectively monitor the pretreatment speed. Under the condition of ensuring the pretreatment quality, the pretreatment speed can be controlled within a faster and more reasonable range, taking into account both the treatment quality and treatment efficiency, which has positive significance for ensuring product quality and improving production efficiency.

[0006] The embodiments of the present invention are implemented as follows:

[0007] An efficient copper-clad steel device, which includes: a pretreatment mechanism and a copper-cladding mechanism. The pretreatment mechanism includes a steel strip conveying assembly, an ultrasonic cleaning tank, a secondary cleaning tank, and a controller.

[0008] The ultrasonic cleaning tank is filled with cleaning liquid, and the secondary cleaning tank is filled with rinsing water. The steel strip conveying assembly is used to convey the steel strip through the ultrasonic cleaning tank and the secondary cleaning tank in sequence.

[0009] A blowing component and a vision component are arranged in the secondary cleaning tank. The blowing component is arranged close to the upward section of the steel strip and is used to blow the rinsing water on the surface of the steel strip towards the bottom of the secondary cleaning tank.

[0010] The vision component is arranged towards the position where the airflow of the blowing component blows on the steel strip to obtain the water flow condition of the rinsing water blown off when the blowing component blows on the surface of the steel strip. The controller is used to adjust the conveying rate of the steel strip by the steel strip conveying assembly according to the water flow condition.

[0011] Further, the air blowing assembly includes an air delivery pipe and an air flow nozzle. The air delivery pipe is arranged along the width direction of the steel strip, and the air flow nozzle is arranged along the radial direction of the air delivery pipe and faces the surface of the steel strip. 5 Further, the air blowing assembly further includes end plates, annular bodies and connecting pieces. There are two groups of end plates, which are respectively arranged at both ends of the air delivery pipe. A number of annular bodies are evenly spaced between the two groups of end plates. Adjacent annular bodies, and between the end plate and the adjacent annular body are fixedly connected by connecting pieces. The connecting pieces are arranged along the radial direction of the annular body, and the connecting pieces are perpendicular to the end plates.

[0012] The end plates are perpendicular to the air delivery pipe and are rotatably fitted to the air delivery pipe. The end plates, the annular bodies and the air delivery pipe are coaxially arranged. There are two groups of air blowing assemblies, which are respectively arranged on both sides of the steel strip and are symmetrically arranged. The outer wall of the annular body is used to abut against the steel strip.

[0013] Further, the distance between adjacent annular bodies and the distance between the end plate and the adjacent annular body are both greater than or equal to 5 times the thickness of the annular body. An air flow nozzle is arranged between each group of adjacent annular bodies and between the end plate and the adjacent annular body.

[0014] Further, the connecting pieces are wedge-shaped, the pointed parts of the connecting pieces face the side where the air delivery pipe is located, and the ends of the connecting pieces far from their pointed parts are fixedly connected between adjacent annular bodies and between the end plate and the adjacent annular body.

[0015] Further, the number of connecting pieces arranged between adjacent annular bodies and between the end plate and the adjacent annular body is one. Among any four adjacent connecting pieces, the four connecting pieces are evenly spaced along the circumferential direction of the air delivery pipe.

[0016] Further, the air blowing assembly further includes: a baffle. The baffle is arranged parallel to the upward section of the steel strip in the secondary cleaning tank, and the baffle covers the annular bodies and the end plates.

[0017] A high-efficiency pretreatment method for copper-clad steel using the above-mentioned high-efficiency copper-clad steel device, which includes:

[0018] Using the vision component to obtain the water flow condition of the rinsing water blown off when the air blowing assembly blows towards the surface of the steel strip, and obtaining the water flow image of the rinsing water blown off on the surface of the steel strip;

[0019] Using the controller to judge the water flow size in the water flow image. If the water flow is large, use the controller to reduce the conveying speed of the steel strip by the steel strip conveying assembly. If the water flow is small, use the controller to increase the conveying speed of the steel strip by the steel strip conveying assembly.

[0020] Further, establish the corresponding relationship between the water flow size in the water flow image and the conveying speed of the steel strip by the steel strip conveying assembly, so that the controller adjusts the conveying speed of the steel strip by the steel strip conveying assembly according to this corresponding relationship.

[0021] Further, determining the water flow rate in the water flow image by the controller includes: evaluating the water flow rate according to the color depth of the water flow in the water flow image and / or the water flow area on the surface of the steel strip.

[0022] The beneficial effects of the technical solutions of the embodiments of the present invention include:

[0023] The high-efficiency copper-clad steel device provided by the embodiments of the present invention uses a vision component to obtain the water flow condition of the flushing water blown off when the blowing component blows towards the surface of the steel strip, and can obtain the water flow image of the water blown off on the surface of the steel strip. The controller is used to judge the water flow rate in the water flow image.

[0024] If the water flow is large, it indicates that the amount of water remaining on the surface of the steel strip is large. In order to ensure that the surface of the steel strip can be fully dried, the conveying speed of the steel strip by the steel strip conveying component should be appropriately reduced, so that the amount of water carried by the steel strip per unit time becomes less, which is convenient for the blowing component to fully remove the remaining water.

[0025] If the water flow is small, it indicates that the blowing component fully meets the current drying requirements and has a margin. At this time, the conveying speed of the steel strip by the steel strip conveying component can be appropriately increased, which can not only improve the pre-treatment efficiency of the steel strip, but also make full use of the drying efficiency of the blowing component to avoid waste of performance margin.

[0026] In this way, by cooperating with the vision component and the blowing component, the balance between the cleaning speed and the drying effect can be achieved, and on the basis of ensuring the pre-treatment effect, the pre-treatment efficiency can be improved as much as possible.

[0027] Generally speaking, the high-efficiency copper-clad steel device provided by the embodiments of the present invention can effectively monitor the pre-treatment speed. Under the condition of ensuring the pre-treatment quality, the pre-treatment speed can be controlled within a faster and more reasonable range, while taking into account both the treatment quality and the treatment efficiency, which has a positive significance for ensuring product quality and improving production efficiency.

[0050] Embodiment

[0051] Please refer to Figure 1 and Figure 2 , this embodiment provides an efficient copper-clad steel device 1000. The efficient copper-clad steel device 1000 includes a pretreatment mechanism 100 and a copper-cladding mechanism 3000. After the steel strip is processed by the pretreatment mechanism 100, the stains on the surface of the steel strip can be cleaned. The steel strip processed by the pretreatment mechanism 100 can be conveyed to the copper-cladding mechanism 3000 for copper cladding. The copper-cladding mechanism 3000 can be copper plating equipment or copper layer cladding equipment, and is not limited thereto.

[0052] The pretreatment mechanism 100 includes a steel strip conveying assembly 200, an ultrasonic cleaning tank 300, a secondary cleaning tank 400, and a controller (not shown in the figure).

[0053] The ultrasonic cleaning tank 300 is filled with a cleaning liquid and is provided with an ultrasonic component (not shown in the figure). The secondary cleaning tank 400 is filled with rinsing water. The steel belt conveying component 200 is used to convey the steel belt through the ultrasonic cleaning tank 300 and the secondary cleaning tank 400 in sequence.

[0054] After the steel belt enters the ultrasonic cleaning tank 300, it is ultrasonically cleaned in the cleaning liquid, which can greatly improve the cleaning effect, and then enters the secondary cleaning tank 400 to be rinsed clean.

[0055] A blowing component 500 and a vision component 600 are arranged in the secondary cleaning tank 400. The blowing component 500 is arranged close to the upward section 2000 of the steel belt and is used to blow the rinsing water on the surface of the steel belt towards the bottom of the secondary cleaning tank 400. The blowing component 500 is used to clean the residual moisture on the surface of the steel belt and help the steel belt dry quickly and thoroughly.

[0056] The vision component 600 is arranged towards the position where the airflow of the blowing component 500 blows on the steel belt to obtain the water flow condition of the rinsing water blown off when the blowing component 500 blows on the surface of the steel belt. The controller is used to regulate the conveying speed of the steel belt by the steel belt conveying component 200 according to the water flow condition. The vision component 600 cooperates with the blowing component 500 to indirectly judge the drying condition of the steel belt by judging the water flow condition.

[0057] Through this design, by using the vision component 600 to obtain the water flow condition of the rinsing water blown off when the blowing component 500 blows on the surface of the steel belt, an image of the water flow blown off on the surface of the steel belt can be obtained. The controller is used to judge the water flow size in the water flow image.

[0058] If the water flow is large, it indicates that there is a large amount of residual water on the surface of the steel belt. In order to ensure that the surface of the steel belt can be dried thoroughly, the conveying speed of the steel belt by the steel belt conveying component 200 should be appropriately reduced, so that the amount of water carried by the steel belt per unit time becomes less, which is convenient for the blowing component 500 to fully remove the residual water.

[0059] If the water flow is small, it indicates that the blowing component 500 can fully meet the current drying requirements and has a margin. At this time, the conveying speed of the steel belt by the steel belt conveying component 200 can be appropriately increased, which can not only improve the pre-treatment efficiency of the steel belt, but also make full use of the drying efficiency of the blowing component 500 and avoid waste of performance margin.

[0060] In this way, by cooperating the vision component 600 and the blowing component, the balance between the cleaning speed and the drying effect can be achieved, and on the basis of ensuring the pre-treatment effect, the pre-treatment efficiency can be improved as much as possible.

[0061] Generally speaking, the efficient copper-clad steel device 1000 can effectively monitor the pre-treatment speed. Under the condition of ensuring the pre-treatment quality, it can control the pre-treatment speed within a faster and more reasonable range, taking into account both the treatment quality and treatment efficiency, which is of positive significance for ensuring product quality and improving production efficiency.

[0062] It can be understood that the vision component 600 includes but is not limited to a camera.

[0063] Please combine Figures 1 to 7 , in this embodiment, the blowing component 500 includes an air delivery pipe 510 and an air flow nozzle 520. The air delivery pipe 510 is arranged along the width direction of the steel strip, and the air flow nozzle 520 is arranged along the radial direction of the air delivery pipe 510 and faces the surface of the steel strip, using the air flow nozzle 520 to clean the residual water on the surface of the steel strip.

[0064] Among them, the blowing component 500 further includes end plates 530, a ring body 540, and connecting pieces 550. There are two groups of end plates 530, which are respectively arranged at both ends of the air delivery pipe 510. A number of ring bodies 540 are evenly spaced between the two groups of end plates 530. The adjacent two ring bodies 540, and between the end plate 530 and the adjacent ring body 540 are fixedly connected through the connecting pieces 550. The connecting pieces 550 are arranged along the radial direction of the ring body 540, and the connecting pieces 550 are all perpendicular to the end plates 530.

[0065] The end plates 530 are perpendicular to the air delivery pipe 510 and are rotatably fitted to the air delivery pipe 510. The end plates 530, the ring body 540, and the air delivery pipe 510 are coaxially arranged. There are two groups of blowing components 500, which are respectively arranged on both sides of the steel strip and are symmetrically arranged. The outer ring wall of the ring body 540 is used to abut against the steel strip.

[0066] The distance between adjacent two ring bodies 540, and the distance between the end plate 530 and the adjacent ring body 540 are both greater than or equal to 5 times the thickness of the ring body 540. An air flow nozzle 520 is arranged between each group of adjacent two ring bodies 540, and between the end plate 530 and the adjacent ring body 540.

[0067] Through this design, the end plates 530, the ring body 540, the connecting pieces 550, and the air delivery pipe 510 form a structure similar to a conveying roller. While cleaning the residual water on the surface of the steel strip, it can also improve the movement stability of the steel strip and prevent the steel strip from shaking under the action of the air flow.

[0068] The air flows out between the ring bodies 540, and between the end plate 530 and the ring body 540. Since the air flow itself has divergence, it can effectively cover the surface of the steel strip to ensure full removal of the residual water.

[0069] Furthermore, the number of connecting pieces 550 provided between two adjacent annular bodies 540, and between the end plate 530 and the adjacent annular body 540 is one. Among any four adjacent connecting pieces 550, the four connecting pieces 550 are evenly spaced along the circumferential direction of the air supply pipe 510. This can effectively reduce the interference of the connecting pieces 550 on the airflow blown out by the air blowing assembly 500.

[0070] Among them, the connecting piece 550 is wedge-shaped, the pointed part of the connecting piece 550 is arranged towards the side where the air supply pipe 510 is located, and one end of the connecting piece 550 far from its pointed part is fixedly connected between two adjacent annular bodies 540, and between the end plate 530 and the adjacent annular body 540.

[0071] Due to the existence of the connecting piece 550, even if the thickness of the connecting piece 550 is small, as the annular body 540 rotates, when the connecting piece 550 moves to the front of the air flow nozzle 520, it will inevitably interfere with the air flow ejected from the air flow nozzle 520.

[0072] Since the connecting piece 550 is wedge-shaped, it can effectively prevent the generation of large-area turbulent flow and effectively reduce the interference on the air flow. On the other hand, the connecting piece 550 has a certain air flow splitting effect. As Figure 8 shown, the air flow is divided into air flow p1 and air flow p2 by the connecting piece 550, which results in a relatively smaller effect of the air flow on the D area of the steel belt behind the connecting piece 550. Although the air flow p2 blows towards the upper end of the D area, since the air flow p2 is only a part of the air flow ejected from the air flow nozzle 520, the air flow cleaning effect on the D area is relatively weak.

[0073] As the steel belt continues to move, the annular body 540 will also rotate accordingly, and the position of the connecting piece 550 changes. As Figure 9 shown, at this time, the position of the D area becomes higher, the connecting piece 550 rotates to a position closer to the steel belt, and under the splitting effect of the connecting piece 550, the air flow is divided into air flow p1' and air flow p2'. As the connecting piece 550 continues to rotate, the proportion of the air flow p1' will become larger and larger, and it can supplement the cleaning of the D area. In addition, although the proportion of the air flow p2' is small, the distance that the air flow p2' blows towards the steel belt is shorter, and the air flow p2' blows towards the upper end of the D area. Generally speaking, the cleaning effect of the air flow p2' on the D area will become stronger, and it can also ensure that the residual water in the D area is cleaned up.

[0074] Through the above design, the cleaning effect of the residual water on the surface of the steel belt is effectively guaranteed.

[0075] Further, the air blowing assembly 500 further includes: a baffle 560. The baffle 560 is arranged parallel to the upward running section 2000 of the steel strip in the secondary cleaning tank 400, and the baffle 560 covers the ring body 540 and the end plate 530 to prevent the water in the secondary cleaning tank 400 from splashing out.

[0076] This embodiment also provides a high-efficiency pretreatment method for copper-clad steel using the above-mentioned high-efficiency copper-clad steel device 1000, which includes:

[0077] Using the vision assembly 600 to obtain the water flow condition of the rinsing water blown off when the air blowing assembly 500 blows towards the surface of the steel strip, and obtaining the water flow image of the rinsing water blown off on the surface of the steel strip;

[0078] Using the controller to judge the size of the water flow in the water flow image. If the water flow is large, use the controller to reduce the conveying speed of the steel strip by the steel strip conveying assembly 200. If the water flow is small, use the controller to increase the conveying speed of the steel strip by the steel strip conveying assembly 200.

[0079] Among them, a corresponding relationship can be established between the size of the water flow in the water flow image and the conveying speed of the steel strip by the steel strip conveying assembly 200, so that the controller adjusts the conveying speed of the steel strip by the steel strip conveying assembly 200 according to this corresponding relationship to improve the adjustment accuracy and adjustment efficiency.

[0080] When the air blowing assembly 500 blows air towards the surface of the steel strip, the residual water on the surface of the steel strip will flow downward and converge under the action of the air flow, forming a water flow that flows along the surface of the steel strip towards the bottom of the secondary cleaning tank 400. Using the controller to judge the size of the water flow in the water flow image includes: evaluating the size of the water flow according to the color depth of the water flow in the water flow image and / or the water flow area on the surface of the steel strip.

[0081] Among them, when the residual water is blown by the air flow, water splashes are easily generated. The more water splashes there are, the whiter the image at the water flow will be. The size of the water flow can be judged by the depth of the white color at the water flow.

[0082] On the other hand, if the area where obvious water flow is generated is larger, it also indicates that the amount of residual water is larger. Therefore, the size of the water flow can also be evaluated by the water flow area on the surface of the steel strip.

[0083] All of these can be determined by analyzing the water flow image on the surface of the steel strip.

[0084] In summary, the high-efficiency copper-clad steel device 1000 provided by the embodiment of the present invention can effectively monitor the pretreatment speed. Under the condition of ensuring the pretreatment quality, the pretreatment speed can be controlled within a faster and more reasonable range, while taking into account the processing quality and processing efficiency, which has a positive significance for ensuring product quality and improving production efficiency.
