Abstract
Description
Technical Field
[0001] This invention relates to the field of steel strip production and processing technology, and in particular to a device for detecting damage to steel strips. Background Technology
[0002] Annealing and straightening are required during the production of steel strip. However, due to processing reasons or external factors, the edges of the steel strip may be damaged or deformed. If straightening is performed on the strip when it is damaged or deformed, the straightening process may cause the strip to tear or even break. Therefore, it is necessary to inspect the steel strip before it enters the annealing and straightening process, and to remind the operator to stop straightening if any damage or deformation is found.
[0003] In existing technologies, a pressure sensor is typically installed at the exit point of the steel strip, with the sensor in contact with the continuously moving steel strip. If the pressure sensor reading fluctuates during the movement of the steel strip, it indicates that the strip has warped or broken. This allows for the detection of damage to the steel strip.
[0004] While this method achieves the desired detection effect, it requires direct contact between the steel belt and the pressure sensor, generating friction between them. This reduces the belt's speed and lowers detection efficiency. Furthermore, with this setup, if the steel belt tilts significantly, the tilted portion will directly impact the pressure sensor as the belt continues to move, potentially damaging it.
[0005] Furthermore, existing testing equipment typically only tests one specification of steel strip, resulting in low applicability. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides a device for detecting damage to steel strips. To achieve the above objective, this invention employs the following technical solution: An apparatus for detecting damage to steel strip includes a support mechanism for forming a movement channel for the steel strip, and a detection mechanism disposed on the support mechanism in a relative manner for detecting damage to the steel strip moving along the channel. The detection mechanism includes an edge-finding module that allows for the identification of the edge position of the steel strip, and a distance sensing module adjacent to the edge-finding module. The distance sensing module is configured to allow for continuous detection of the distance between the steel strip and the edge-finding module. It also includes a drive mechanism mounted on the support mechanism, the drive mechanism being configured to be connected to the detection mechanism and allowing the detection mechanism to move in a direction perpendicular to the channel.
[0007] Furthermore, the edge-finding module includes a first sensor and a second sensor adjacent to the first sensor. Both the first and second sensors are configured to identify the steel strip, so that the distance sensing module, which is arranged adjacent to the edge-finding module, can be located at the edge of the steel strip.
[0008] Furthermore, the drive mechanism includes a track mounted on the support mechanism, a movable part located on the track and allowed to move along the track, and a drive unit connected to the movable part for driving the movable part to move along the track. The edge-finding module and the distance sensing module are configured to be mounted on the moving part, with the edge-finding module located outside the distance sensing module.
[0009] Furthermore, inwardly recessed limiting grooves are provided on both sides of the track. The moving part includes a moving block sleeved on the track and allowed to cooperate with the limiting groove, and a force-bearing component fixed relative to the moving block and allowed to cooperate with the driving part.
[0010] Furthermore, the force-bearing component includes a force-bearing block fixed relative to the moving block, connecting plates disposed on both sides of the force-bearing block and extending outward, the connecting plates being configured to allow the edge-finding module and the distance sensing module to be received and fixed relative to them, so as to separate them from the force-bearing block.
[0011] Furthermore, the drive unit includes a ball screw mounted on the force-bearing block and a motor mounted on the support mechanism and connected to the ball screw to drive the ball screw to rotate, thereby causing the moving part to move along the track.
[0012] Furthermore, the drive unit also includes a support block disposed opposite to the support mechanism. The support block has a through hole through which the ball screw passes. The diameter of the through hole is configured to be similar to the diameter of the ball screw, so as to support the ball screw.
[0013] Furthermore, the device also includes a receiving mechanism disposed on the support mechanism, the receiving mechanism including a receiving portion for carrying the track and a connecting portion disposed on the receiving portion and extending upward thereon, the connecting portion being provided with a mounting groove configured to allow the accommodation of a limit sensor to limit the continuous movement of the detection mechanism.
[0014] Furthermore, the support mechanism includes a horizontally arranged support rod for supporting the detection mechanism and the drive mechanism, and support frames arranged at both ends of the support rod to separate the support rod from the horizontal plane, so that the support rod and the horizontal plane together form a channel for the movement of the steel belt.
[0015] Furthermore, the device also includes a control module, which is connected to the edge-finding module, the distance sensing module, the limit sensor, and the motor in a wired or wireless manner, and allows it to control the opening, closing, and movement direction of the motor based on the information transmitted by the edge-finding module, the distance sensing module, and the limit sensor.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, a support mechanism is provided to form a steel strip movement channel. A detection mechanism is mounted on the support mechanism in a relative manner to detect damage to the steel strip moving along the channel. The detection mechanism includes an edge-finding module that allows identification of the steel strip's edge position, and a distance sensing module adjacent to the edge-finding module. The distance sensing module is configured to continuously detect the distance between the steel strip and the sensor. Specifically, when the distance threshold between the distance sensing module and the steel strip is not equivalent to the distance between an intact steel strip and the distance sensing module, the distance sensing module issues a second warning signal. With this configuration, the detection of the steel strip can be performed without contact with it, thus protecting the detection equipment.
[0017] 2. This invention also includes a driving mechanism, which is connected to the detection mechanism and allows the detection mechanism to move in a direction perpendicular to the channel. In this way, the relative distance between the opposing detection mechanisms can be adjusted according to the specifications of the steel strip, making the device applicable to steel strips of different specifications. This improves the applicability of the device. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] To better understand the purpose, structure, and function of the present invention, the following detailed description of a device for detecting damage to steel strips is provided in conjunction with the accompanying drawings.
[0022] Figure 1 The illustration schematically shows an apparatus for detecting damage to steel strips according to the present invention. In such a way... Figure 1 In the illustrated embodiment, the apparatus 100 for detecting damage to the steel strip includes a support mechanism 1 disposed on a horizontal plane (foundation or the like) to form a channel 11 for the movement of the steel strip. A detection mechanism 2 is disposed on the support mechanism 1 in a counter-arranged manner, the detection mechanism 2 being configured to allow damage detection of the steel strip moving along the channel 11.
[0023] In this embodiment, as Figure 2 As shown, the detection mechanism 2 includes an edge-finding module 21 configured to allow identification of the edge position of the steel strip. It also includes a distance sensing module 22 adjacent to the edge-finding module 21, configured to allow continuous detection of the distance between the steel strip and the sensor.
[0024] It should be noted that in actual production, the edges of the steel strip are most prone to damage. Therefore, the edge-finding module 21 is needed to identify the edge position of the steel strip, causing the distance sensing module 22 to move to that position, thereby enabling damage detection of the steel strip. Specifically, when the steel strip warps, bends, or breaks, the distance between the steel strip and the distance sensing module 22 will differ.
[0025] For example, the distance between a healthy steel belt and the distance sensing module 22 is 400mm. As the steel belt continues to move, if the distance between the steel belt and the distance sensing module 22 is greater than or less than 400mm, it indicates that the steel belt is damaged. Thus, the distance sensing module 22 can detect the integrity of the steel belt.
[0026] Furthermore, in this implementation, such as Figure 2 As shown, the edge-finding module 21 is configured to issue a first warning signal when it is located at the edge of the steel strip to alert the operator. Simultaneously, the distance sensing module 22 is configured to issue a signal to stop the steel strip and a second warning signal when it detects an abnormal distance between itself and the steel strip, thus reminding the operator to straighten the steel strip.
[0027] The first and second reminder signals include, but are not limited to, audible and visual reminders. The issuance of the first and second reminder signals, as well as the signal indicating that the steel belt stops moving, through the edge-finding module 21 are well-known to those skilled in the art. Therefore, the specific principles will not be elaborated upon here.
[0028] In this embodiment, as Figure 1 As shown, the device 100 also includes a drive mechanism 3 disposed on the support mechanism 1. The drive mechanism 3 is configured to be connected to the detection mechanism 2 and allows the detection mechanism 2 to move in a direction perpendicular to the channel 11.
[0029] In this way, such as Figure 1 , 2 As shown, the relative distance between the detection mechanisms 2, which are arranged in a relative manner, can be adjusted so that both the edge-finding module 21 and the distance sensing module 22 are located at the edge of the steel strip. Therefore, the relative distance between the detection mechanisms 2 can be adjusted according to different orientations of the steel strip width. This allows the device 100 to be applied to steel strips of different widths, thereby increasing the applicability of the device 100.
[0030] In this configuration, such as Figure 1 , 2 As shown, in use, the steel strip is first placed in channel 11. Simultaneously, the relative distance between the detection mechanisms 2 is adjusted via the drive mechanism 3. During this process, when the distance between the edge-finding modules 21 is approximately equal to the width of the steel strip, the edge-finding module 21 will issue a first warning signal.
[0031] At this point, both the edge-finding module 21 and the distance sensing module 22 will be located at the edge of the steel strip. Furthermore, the threshold value of the distance sensing module 22 is set such that the distance threshold between the distance sensing module 22 and the steel strip is approximately equal to the distance between the intact steel strip and the distance sensing module 22. Thus, the arrangement of the device 100 is completed.
[0032] At this time, the steel belt continues to move along channel 11. During this process, the distance sensing module 22 continuously detects the distance between the steel belt and the distance sensing module 22, and sends a signal to stop the steel belt when the distance between the steel belt and the distance sensing module 22 exceeds its threshold range. Thus, damage detection of the steel belt is achieved.
[0033] In one embodiment, such as Figure 2 As shown, the edge-finding module 21 includes a first sensor 211 and a second sensor 212 adjacent to the first sensor 211. Specifically, the first sensor 211 and the second sensor 212 are positioned on the same horizontal plane and spaced apart from each other. Both the first sensor 211 and the second sensor 212 are configured to identify the steel strip. In this way, the edge of the steel strip is identified.
[0034] Specifically, such as Figure 2 As shown, when the first sensor 211 located on the outer side fails to detect the steel strip, while the second sensor 212 located on the inner side detects the steel strip, it indicates that the edge of the steel strip is located between the first sensor 211 and the second sensor 212. In this way, the edge-finding module 21 can identify the position of the steel strip edge, thereby ensuring that the distance sensing module 22, which is adjacent to the edge-finding module 21, is located at the edge of the steel strip.
[0035] In one embodiment, such as Figure 3 , 4 As shown, the drive mechanism 3 includes a track 31 fixed relative to the support mechanism 1, and a moving part 32 disposed on the track 31. The moving part 32 is configured to cooperate with the track 31, allowing the moving part 32 to move along the path formed by the track 31. Furthermore, the drive mechanism 3 also includes a drive part 33, which is configured to be connected to the moving part 32 and allows a force to be applied to the moving part 32, causing the moving part 32 to move along the track 31 under the action of the drive part 33.
[0036] In the illustrated embodiment, such as Figure 4As shown, the edge-finding module 21 and the distance sensing module 22 are configured to be mounted on the moving part 32, with the edge-finding module 21 located outside the distance sensing module 22. In this way, as the moving part 32 moves along the track 31, it can drive the edge-finding module 21 and the distance sensing module 22 to move synchronously, thereby positioning the edge-finding module 21 and the distance sensing module 22 at the edge of the steel strip.
[0037] According to a preferred embodiment of the present invention, such as Figure 4 As shown, inwardly recessed limiting grooves 311 are provided on both sides of the track 31. Meanwhile, as... Figure 5 As shown, the moving part 32 includes a moving block 321, which is fitted onto the track 31 and allows it to engage with the limiting groove 311. In this way, the moving block 321 can only move along the path formed by the track 31, thereby avoiding deviation during the movement of the moving block 321.
[0038] In addition, such as Figure 4 , 5 As shown, a force-receiving component 322 is also fixedly arranged on the movable block 321. The force-receiving component 322 is configured to cooperate with the drive unit 33 to receive the force from the drive unit 33, thereby causing the force-receiving component 322 to drive the movable block 321 to move synchronously under the force of the drive unit 33. It should be noted that the force-receiving component 322 is configured to receive the edge-finding module 21 and the distance sensing module 22, and fix them relatively together.
[0039] In this embodiment, as Figure 4 , 5 As shown, the force-receiving component 322 includes a force-receiving block 3221 fixed relative to the moving block 321, and connecting plates 3222 disposed on both sides of the force-receiving block 3221 and extending outward. The connecting plates 3222 are configured to receive the edge-finding module 21 and the distance sensing module 22, and are fixed relative to them. In this way, the edge-finding module 21, the distance sensing module 22, and the force-receiving block 3221 can be separated from each other, thereby avoiding interference between the drive mechanism 3 and the edge-finding module 21 and the distance sensing module 22.
[0040] In one embodiment, such as Figure 3 , 4 As shown, the drive unit 33 includes a ball screw 331, which passes through and cooperates with the force-receiving block 3221. In this way, the ball screw 331 can apply a force to the force-receiving block 3221 during rotation, thereby driving the force-receiving block 3221 to move.
[0041] In addition, such as Figure 3 As shown, the drive unit 33 also includes a motor 332 mounted on the support mechanism 1. The motor 332 is configured to be connected to the ball screw 331 and allows the ball screw 331 to rotate, thereby causing the moving part 32 to move along the track 31. It should be noted that the structures of the ball screw 331 and the motor 332, as well as their cooperation and transmission relationships, are well known to those skilled in the art. Therefore, they will not be described in detail here.
[0042] In one embodiment, such as Figure 2 , 7 As shown, the driven part 33 also includes a support block 333 fixedly mounted on the support mechanism 1. A through hole 3331 is provided on the support block 333, which is configured to accommodate the ball screw 331. At the same time, the diameter of the through hole 3331 is configured to be approximately the same as the diameter of the ball screw 331.
[0043] In this way, the support block 333 can support the ball screw 331, thereby enabling the ball screw 331 to be stably set and rotated. Preferably, the support block 333 is located at the end of the ball screw 331 so that the ball screw 331 can be set in a balanced manner.
[0044] In one embodiment, such as Figure 1 , 6 As shown, the device 100 also includes a receiving mechanism 4 disposed on the support mechanism 1. The receiving mechanism 4 includes a receiving portion 41 for supporting the track 31 and a connecting portion 42 disposed on the receiving portion 41 and extending upward. In this way, the track 31 and the moving block 321 that cooperates with the track 31 can be sealed, thereby protecting the track 31 and the moving block 321.
[0045] In addition, such as Figure 4 , 6 As shown, a mounting groove 421 is also provided on the connecting part 42. The mounting groove 421 is configured to accommodate a limit sensor 5 to limit the continuous movement of the detection mechanism 2. Specifically, the limit sensor 5 is configured to stop the motor 332 when it detects the moving part 32. This prevents the moving part 32 from moving continuously. Preferably, at least two limit sensors 5 are provided and are located at both ends of the track 31. In this way, they constitute the movement range of the moving part 32.
[0046] According to a preferred embodiment of the present invention, such as Figure 2As shown, the receiving mechanism 4 also includes a cover plate 43, which is configured to cover the connecting portion 42 in a relatively fixed manner, so that the receiving mechanism 4 forms a sealed cavity. This protects the detection mechanism 2 and the drive mechanism 3.
[0047] In one embodiment, such as Figure 1 As shown, the support mechanism 1 includes a support rod 12 arranged horizontally to support the detection mechanism 2 and the drive mechanism 3, and a support frame 13 arranged at both ends of the support rod 12 to separate the support rod 12 from the horizontal plane.
[0048] In this way, such as Figure 1 As shown, this allows the support rod 12 and the horizontal plane to jointly form a channel 11 for the movement of the steel belt. Preferably, the support mechanism 1 further includes a connecting frame 14, which is disposed at both ends of the support frame 13 and fixed to the support frame 13. In this way, the support mechanism 1 stably supports the detection mechanism 2, the drive mechanism 3, and the receiving mechanism 4, forming a stable channel 11.
[0049] In one embodiment, such as Figure 2 As shown, the device 100 also includes a control module (not shown in the figure). The control module is connected to the edge-finding module 21, the distance sensing module 22, the limit sensor 5, and the motor 332 in a wired or wireless manner, and allows it to control the opening, closing, and movement direction of the motor 332 according to the information transmitted by the edge-finding module 21, the distance sensing module 22, and the limit sensor 5.
[0050] Specifically, the control module can start the motor 332 based on the information transmitted by the edge-finding module 21, thereby causing the motor 332 to rotate and drive the moving part 32 to move on the track 31 until the edge-finding module 21 is located at the edge of the steel strip. At this time, the control module will activate the distance sensing module 22 and make the distance sensing module 22 continuously detect the steel strip and the distance between it.
[0051] However, as the moving part 32 continues to move on the track 31, and the edge-finding module 21 still fails to detect the steel strip after the limit sensor 5 detects the moving part 32, the control module shuts down the motor 332 to protect the device 100. It should be noted that the connection relationships, signal transmission relationships, and control principles between the control module, edge-finding module 21, distance sensing module 22, limit sensor 5, and motor 332 are well-known to those skilled in the art. Therefore, they will not be described in detail here.
[0052] The operation of the apparatus 100 for detecting damage to steel strip according to the present invention is as follows.
[0053] First, the steel strip is placed in channel 11. Simultaneously, the control module (not shown in the figure), edge-finding module 21, distance sensing module 22, limit sensor 5, and motor 332 are activated. At this time, the control module will directionally start motor 332 based on the information transmitted from edge-finding module 21, causing motor 332 to move and drive moving part 32 on track 31 until edge-finding module 21 is located at the edge of the steel strip.
[0054] At this time, the distance sensing module 22 is activated via the control module. Simultaneously, the steel belt continues to move along the channel 11. During this process, the distance sensing module 22 continuously detects the distance between the steel belt and the module, and sends a signal to stop the steel belt when the distance exceeds its threshold range. This achieves damage detection of the steel belt.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
