Description

Technical Field

[0001] This invention relates to the field of laser detection technology for steel strips, specifically to a laser surface identification and detection device for ultra-thin high-temperature alloy steel strips. Background Technology

[0002] Ultra-thin steel strip typically refers to steel strip with an extremely thin thickness (generally less than 0.2 mm, with some high-end fields having even stricter thickness requirements). It combines the strength and toughness of steel with the special properties brought by its ultra-thin dimensions, and has important applications in many fields.

[0003] Chinese patent CN221325411U discloses a burr detection system aimed at solving the problem of simultaneously detecting burrs on the upper and lower surfaces of silicon steel strip during the discharge of a silicon steel slitting line. This invention includes a silicon steel slitting line, a gantry frame, two sets of actuators, a control unit, and corresponding line laser sensors. Each set of actuators also includes a limit unit and a cable chain unit. Based on existing silicon steel slitting lines, this invention sets two sets of actuators, corresponding to the upper and lower surfaces respectively, along the path after the material exits from the cutter holder. The actuators can move along the height and strip width directions under signal control. Line laser sensors at the ends of the actuators extract the outline information of burrs. When the burr error exceeds the standard, an alarm is issued, thereby improving the production yield.

[0004] While existing technologies can use line laser sensors to detect the surface contour of cut steel edges and determine the presence of burrs, they are not suitable for inspecting ultra-thin steel strips due to their thinness. Excessive tension during transport after cutting can cause deformation. This inability to achieve proper tension leads to sag changes due to weight and mechanical vibrations, causing spatial deviations between the laser scanning path and the strip edge. Consequently, continuous and accurate inspection is impossible, limiting the detection to static ultra-thin steel strip contours and significantly impacting inspection efficiency. Summary of the Invention

[0005] To address the aforementioned issues, a laser surface recognition and detection device for ultra-thin steel strips made of high-temperature alloys is provided. The adaptive detection device can effectively improve detection efficiency and accuracy.

[0006] To address the problems of existing technologies, this invention provides a laser surface recognition and detection device for high-temperature alloy ultrathin steel strips. The device includes an adaptive detection device installed below a cutting device. The adaptive detection device includes a misalignment guide frame installed below the cutting device, which guides the misaligned movement of the cut ultrathin steel strip. Multiple movable adjustment devices are installed below the misalignment guide frame. Each movable adjustment device has a clamping device installed at its movable end. Each movable adjustment device is used to adjust the position of the clamping device. The clamping device is used to limit and clamp the ultrathin steel strip to its outer side. A laser detection device is installed on the clamping device, and two laser detectors are installed on the laser detection device. The laser detectors are used to detect the cut surface of the ultrathin steel strip.

[0007] Preferably, the movable adjustment device includes an adjustment screw slide, an adjustment frame is mounted on the movable end of the adjustment screw slide, and a movable connection structure is mounted on the adjustment frame for connecting the clamping device.

[0008] Preferably, the movable connection structure consists of two movable joints. Each movable joint has a limiting mounting hole inside.

The end of each first spring away from the buffer connecting shaft contacts the movable joint. Second springs are installed at both ends of the buffer connecting shaft. The end of the second spring away from the buffer connecting shaft contacts the movable joint.

[0009] Preferably, the clamping device includes a synchronous shrinking device mounted on the movable adjustment device, and a limit adjustment tool and a pressing adjustment tool are mounted on the synchronous shrinking device. The gap between the limit adjustment tool and the pressing adjustment tool is used to limit and clamp the cut ultra-thin steel strip.

[0010] Preferably, the limiting adjustment device consists of two limiting mounting blocks. Each limiting mounting block has a synchronous guide post at its top and an L-shaped limiting groove on its side. The bottom of the L-shaped limiting groove is equipped with multiple abutting rollers, and the side of the L-shaped limiting groove is also equipped with multiple side limiting rollers. The side of the limiting mounting block is equipped with a first limiting slide groove for slidingly connecting the synchronous retraction device. The two limiting mounting blocks are equipped with a spacing adjustment mechanism for adjusting the position of the two limiting mounting blocks.

[0011] Preferably, the spacing adjustment mechanism includes a first connecting seat and a second connecting seat, which are respectively mounted on two limiting mounting blocks. The first connecting seat is provided with a limiting slot, and two sliding guide posts are also mounted on the first connecting seat. The end of the sliding guide post away from the first connecting seat passes through the second connecting seat. A third spring is installed between the sliding guide post and the second connecting seat. A spacing adjustment shaft is rotatably mounted on the second connecting seat, and multiple adjusting rings are provided on the outer side of the spacing adjustment shaft.

[0012] Preferably, the pressing adjustment device includes two pressing blocks, each pressing block has a second limiting groove on its side, the second limiting groove is used to connect the synchronous contraction device, an assembly guide post is installed between the two pressing blocks, the bottom of the two pressing blocks has a limiting docking hole, the limiting docking hole is slidably docked with the synchronous guide post, and the bottom of each pressing block has multiple pressing rollers.

[0013] Preferably, the synchronous retraction device includes two mounting brackets installed on both sides of the limiting adjustment tool and the pressing adjustment tool. The mounting brackets are provided with connecting slide rails, which are slidably connected to the first limiting slide groove and the second limiting slide groove. The synchronous retraction device also includes two synchronous connecting strips distributed on the limiting mounting block and the pressing block. A connecting block is installed between the two synchronous connecting strips. A sliding connecting shaft is slidably installed on the connecting block. A fourth spring is installed between the sliding connecting shaft and the connecting block. A linear driver is also installed on the mounting bracket.

[0014] Preferably, the laser detection device includes a flow guide frame mounted on a clamping device. The flow guide frame is used to fix the laser detector. The flow guide frame has an inclined flow guide plate inside, which is used to guide the air to blow towards the laser detector.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. This invention effectively solves the problem of dynamic detection of ultra-thin steel strips, improving detection efficiency and accuracy: Traditional technologies for detecting ultra-thin steel strips suffer from sag and fluctuation due to the inability to over-tension the strip during transport. This leads to spatial positional deviations between the laser scanning path and the strip edge, limiting detection to static contours and significantly impacting efficiency. This device, however, guides the cut ultra-thin steel strip with a staggered guide frame, utilizing multiple adjustable and clamping devices working in tandem. When the ultra-thin steel strip slightly shifts due to limited tension during movement, the clamping device, adjusted by the adjustable devices, adapts to the shift, maintaining synchronous movement with the strip. This ensures the laser detector maintains a constant relative position with the cut surface. This enables real-time detection of the dynamically moving cut surface, effectively solving the problem of continuous and accurate detection of dynamic ultra-thin steel strips using traditional techniques, significantly improving detection efficiency and accuracy.

[0017] 2. This invention features an adaptive adjustment function, enhancing its applicability: Before the cutting operation, the operator can pre-adjust the clamping dimensions of the clamping device according to the size of the ultra-thin steel strip to be cut, ensuring that the clamping area of ​​the clamping device is compatible with the thin steel strip. The clamping device can then be adjusted to a suitable position using the movable adjustment device. The clamping device can move adaptively at multiple angles at the adjustment end of the movable adjustment device. This adaptive adjustment function allows the invention to adapt to the inspection needs of ultra-thin steel strips of different sizes and specifications, enhancing its applicability.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] See Figures 1 to 11 As shown, a laser surface recognition and detection device for ultra-thin high-temperature alloy steel strip includes an adaptive detection device installed below a cutting device. The adaptive detection device includes a misalignment guide frame 1 installed below the cutting device. The misalignment guide frame 1 is used to guide the misaligned movement of the cut ultra-thin steel strip 5. Multiple movable adjustment devices 2 are installed below the misalignment guide frame 1. Each movable adjustment device 2 has a clamping device 3 installed at its movable end. Each movable adjustment device 2 is used to adjust the position of the clamping device 3. The clamping device 3 is used to limit and clamp the ultra-thin steel strip 5 on its outer side. A laser detection device 4 is installed on the clamping device 3. Two laser detectors 42 are installed on the laser detection device 4. The laser detectors 42 are used to detect the cut surface of the ultra-thin steel strip 5.

[0033] Before the cutting operation, the staff adjusts the clamping dimensions of the clamping device 3 according to the dimensions of the ultra-thin steel strip 5 to be cut, ensuring that the clamping area of ​​the clamping device 3 is compatible with the thin steel strip. The clamping device 3 is then adjusted to a suitable position using the movable adjustment device 2. The clamping device 3 can move adaptively at multiple angles at the adjustment end of the movable adjustment device 2.

[0034] After the cutting equipment cuts the ultra-thin steel strip 5, the worker passes the cut ultra-thin steel strip 5 through the misalignment guide frame 1. The misalignment guide frame 1 guides the cut ultra-thin steel strip 5 in a misaligned manner, so that the two ultra-thin steel strips 5 pass through their respective misalignment guide frames 1. Subsequently, the ultra-thin steel strip 5 passes through the clamping device 3 and connects to the steel coil winding device, completing the installation of the steel strip. At this time, the laser detector 42 on the clamping device 3 is in a ready-to-inspection state, preparing to inspect the cut surface of the ultra-thin steel strip 5.

[0035] The cutting equipment continuously cuts the ultra-thin steel strip 5, while the coil winding device winds it up, allowing it to continuously pass through the clamping device 3. Due to the thinness of the ultra-thin steel strip 5, the tension during winding is limited to prevent deformation, causing slight deviation during its movement. When this deviation occurs, the clamping device 3 and the movable adjustment device 2 work together to adaptively adjust the displacement based on the deviation. The clamping device 3 always moves synchronously with the ultra-thin steel strip 5, ensuring that the laser detector 42 maintains a relative position with the cut surface of the ultra-thin steel strip 5, thus ensuring accurate detection. The laser detector 42 performs real-time detection of the cut surface of the ultra-thin steel strip 5. Once an abnormality is detected in the cut surface contour of the ultra-thin steel strip 5, it is determined that burrs have appeared during the cutting process, triggering an alarm signal to prompt maintenance of the cutting equipment.

[0036] The cutting equipment and the steel coil winding device both use existing technologies, and their specific working principles will not be described in detail here.

[0037] See Figures 1 to 5 As shown, the movable adjustment device 2 includes an adjustment screw slide 21, an adjustment frame 22 is installed on the movable end of the adjustment screw slide 21, and a movable connection structure 23 is installed on the adjustment frame 22. The movable connection structure 23 is used to connect the clamping device 3.

[0038] During the installation and commissioning phase of the device, based on the cutting position, conveying path, and testing requirements of the ultra-thin steel strip 5, the operation of the adjusting screw slide 21 is controlled to drive the adjusting frame 22 to move horizontally. During the horizontal movement of the adjusting frame 22, the movable connecting structure 23 installed on the adjusting frame 22 will move simultaneously.

[0039] The movable connecting structure 23 is connected to the clamping device 3. As the movable connecting structure 23 moves, the clamping device 3 will also move horizontally to achieve precise adjustment of the initial position of the clamping device 3, ensuring that the clamping device 3 can be accurately positioned in the appropriate position on the conveying path of the ultra-thin steel belt 5, thus preparing for subsequent clamping and inspection work.

[0040] When the cutting equipment continuously cuts the ultra-thin steel strip 5 and the steel coil winding device winds the ultra-thin steel strip 5, the ultra-thin steel strip 5 is thin and the winding tension is limited to avoid deformation, so the ultra-thin steel strip 5 will slightly deviate during the movement.

[0041] At this point, the clamping device 3 is clamped onto the cut ultra-thin steel strip 5. The movable connecting structure 23 has an adaptive adjustment function. When the ultra-thin steel strip 5 shifts, the movable connecting structure 23 can automatically adjust its connection with the clamping device 3, allowing the clamping device 3 to make fine adjustments.

[0042] With the cooperation of the movable connecting structure 23, the clamping device 3 moves and adjusts synchronously with the ultra-thin steel strip 5. Since the laser detection device 4 is mounted on the clamping device 3, the synchronous movement and adjustment of the clamping device 3 can ensure that the laser detector 42 always maintains an accurate detection position, so that the laser detector 42 and the cutting surface of the ultra-thin steel strip 5 maintain a relatively stable positional relationship, thereby ensuring the accuracy and continuity of the contour detection of the cutting surface of the ultra-thin steel strip 5.

[0043] See Figures 5 to 8 As shown, the movable connection structure 23 consists of two movable joints 231. Each movable joint 231 has a limiting mounting hole 232 inside. A buffer connecting shaft 233 is provided at the axial position of the limiting mounting hole 232. Multiple first springs 234 are installed on the outside of the buffer connecting shaft 233. The end of each first spring 234 away from the buffer connecting shaft 233 contacts the movable joint 231. Second springs 235 are installed at both ends of the buffer connecting shaft 233. The end of the second spring 235 away from the buffer connecting shaft 233 contacts the movable joint 231.

[0044] The clamping device 3 is connected to the buffer connecting shafts 233 of the two movable joints 231 respectively. The clamping device 3 is fixedly connected to the buffer connecting shaft 233 of one of the movable joints 231, and the clamping device 3 is slidably connected to the buffer connecting shaft 233 of the other movable joint 231. When the clamping device 3 needs to be adjusted, the size of the clamping device 3 will change. One side of the clamping device 3 is slidably connected to the movable joint 231 to facilitate the adjustment of the clamping device 3.

[0045] When the cutting equipment continuously cuts the ultra-thin steel strip 5 and the coil winding device winds it up, the ultra-thin steel strip 5 is thin, and the winding tension is limited to avoid deformation, causing the ultra-thin steel strip 5 to slightly shift during movement. At this time, the clamping device 3, which is already clamped on the ultra-thin steel strip 5, moves synchronously with the ultra-thin steel strip 5.

[0046] When the clamping device 3 moves up, down, left, and right along with the ultra-thin steel strip 5, the first spring 234 on the outer side of the buffer connecting shaft 233 inside the movable joint 231, which is fixedly connected to the clamping device 3, undergoes elastic deformation. The first spring 234, through its own elastic expansion and contraction, adapts to the displacement of the clamping device 3 in the up, down, left, and right directions, while simultaneously providing a restoring force to the buffer connecting shaft 233, allowing the buffer connecting shaft 233 to move and adjust accordingly within the movable joint 231, thereby providing the clamping device 3 with a range of motion in the up, down, left, and right directions.

[0047] When the clamping device 3 moves laterally with the ultra-thin steel strip 5, the second springs 235 at both ends of the buffer connecting shaft 233, which is slidably connected to the clamping device 3, undergo elastic deformation. The second springs 235, through their own elastic expansion and contraction, adapt to the lateral displacement of the clamping device 3 and simultaneously provide a restoring force to the buffer connecting shaft 233, allowing the buffer connecting shaft 233 to move and adjust accordingly within the movable joint 231, thereby providing the clamping device 3 with a lateral range of motion.

[0048] Through the coordinated action of the first spring 234 and the second spring 235, the movable connecting structure 23 can automatically adjust the position of the buffer connecting shaft 233 within the movable joint 231 according to the offset of the ultra-thin steel strip 5, thereby enabling the clamping device 3 to make micro-adjustments and always maintain synchronous movement with the ultra-thin steel strip 5. Since the laser detection device 4 is mounted on the clamping device 3, the synchronous movement adjustment of the clamping device 3 ensures that the laser detector 42 always maintains an accurate detection position and a relatively stable positional relationship with the cutting surface of the ultra-thin steel strip 5, thereby ensuring the accuracy and continuity of the contour detection of the cutting surface of the ultra-thin steel strip 5.

[0049] See Figures 1 to 7 As shown, the clamping device 3 includes a synchronous shrinking device 33 mounted on the movable adjustment device 2. The synchronous shrinking device 33 is equipped with a limit adjustment tool 31 and a pressing adjustment tool 32. The gap between the limit adjustment tool 31 and the pressing adjustment tool 32 is used to limit and clamp the cut ultra-thin steel strip 5.

[0050] The synchronous shrinking device 33 is mounted on the movable adjustment device 2, providing the mounting base and adjustment power for the entire clamping device 3. The limit adjustment device 31 and the pressing adjustment device 32 are both mounted on the movable end of the synchronous shrinking device 33, and the gap between them is used to limit and clamp the cut ultra-thin steel strip 5.

[0051] After the cutting equipment cuts the ultra-thin steel strip 5, the worker passes the cut ultra-thin steel strip 5 through the gap between the limiting adjustment device 31 and the pressing adjustment device 32. At this time, the synchronous shrinking device 33 further controls the movement of the movable end according to the preset clamping parameters, so that the limiting adjustment device 31 and the pressing adjustment device 32 cooperate with each other to apply a suitable clamping force to the ultra-thin steel strip 5, thereby achieving limiting clamping.

[0052] See Figures 4 to 10 As shown, the limiting adjustment device 31 consists of two limiting mounting blocks 311. Each limiting mounting block 311 has a synchronous guide post 3115 on its top and an L-shaped limiting groove 3111 on its side. Multiple abutting rollers 3113 are installed at the bottom of the L-shaped limiting groove 3111. Multiple side limiting rollers 3114 are also provided on the side of the L-shaped limiting groove 3111. A first limiting slide groove 3112 is provided on the side of the limiting mounting block 3111. The first limiting slide groove 3112 is used to slide and connect the synchronous retraction device 33. A spacing adjustment mechanism 312 is installed on the two limiting mounting blocks 311. The spacing adjustment mechanism 312 is used to adjust the position of the two limiting mounting blocks 311.

[0053] The limiting adjustment device 31 consists of two limiting mounting blocks 311. Each limiting mounting block 311 has a synchronous guide post 3115 on its top for sliding connection with the pressing adjustment device 32, ensuring synchronicity between the two during adjustment. The limiting mounting block 311 has an L-shaped limiting groove 3111, with multiple abutment rollers 3113 installed at the bottom and multiple side limiting rollers 3114 on its side for contact with the ultra-thin steel strip 5, reducing friction during movement. The limiting mounting block 311 has a first limiting slide groove 3112 on its side, through which it slides to connect with the synchronous retraction device 33, enabling the installation and movement adjustment of the limiting mounting block 311 on the synchronous retraction device 33. A spacing adjustment mechanism 312 is installed on the two limiting mounting blocks 311 for adjusting the positional relationship between them.

[0054] Before the cutting operation, the operator adjusts the spacing between the two limiting mounting blocks 311 according to the width of the ultra-thin steel strip 5 to be cut, using the spacing adjustment mechanism 312. Since the two limiting mounting blocks 311 are connected by the spacing adjustment mechanism 312, when the adjustment mechanism is activated, the two limiting mounting blocks 311 will move synchronously, thereby changing the width of the L-shaped limiting groove 3111 accordingly. This ensures that the width of the L-shaped limiting groove 3111 matches the width of the ultra-thin steel strip 5, preparing for subsequent limiting clamping.

[0055] After the cutting equipment cuts the ultra-thin steel strip 5, the worker places the cut ultra-thin steel strip 5 into the L-shaped limiting grooves 3111 of the two limiting mounting blocks 311. At this time, the L-shaped limiting grooves 3111 provide initial limiting for the ultra-thin steel strip 5. Simultaneously, the side limiting rollers 3114 on the side of the L-shaped limiting grooves 3111 contact both sides of the ultra-thin steel strip 5, providing lateral limiting for the ultra-thin steel strip 5. Subsequently, the synchronous shrinking device 33 is activated, driving the pressing adjustment device 32 and the limiting mounting blocks 311 to shrink synchronously. During the shrinking process, the pressing adjustment device 32, guided by the synchronous guide column 3115, applies downward pressure to the ultra-thin steel strip 5, causing the bottom surface of the ultra-thin steel strip 5 to contact the abutting rollers 3113 at the bottom of the L-shaped limiting grooves 3111. The ultra-thin steel strip 5 is clamped and positioned by the pressing action of the pressing adjustment tool 32 and the limiting action of the L-shaped limiting groove 3111.

[0056] During the continuous cutting of the ultra-thin steel strip 5 by the cutting equipment and the winding operation of the steel coil 5 by the coil winding device, the ultra-thin steel strip 5 needs to move within the clamping device 3. Since the bottom of the L-shaped limiting groove 3111 is equipped with an abutment roller 3113 and the side is provided with a side limiting roller 3114, when the ultra-thin steel strip 5 moves, the abutment roller 3113 and the side limiting roller 3114 will roll accordingly, thereby effectively reducing the friction force when the ultra-thin steel strip 5 moves, ensuring that the ultra-thin steel strip 5 can move smoothly and meet the needs of continuous production.

[0057] See Figure 9 and Figure 10 As shown, the spacing adjustment mechanism 312 includes a first connecting seat 3121 and a second connecting seat 3123. The first connecting seat 3121 and the second connecting seat 3123 are respectively mounted on two limiting mounting blocks 311. The first connecting seat 3121 is provided with a limiting slot 3122. Two sliding guide posts 3124 are also installed on the first connecting seat 3121. One end of the sliding guide post 3124 away from the first connecting seat 3121 passes through the second connecting seat 3123. A third spring 3125 is installed between the sliding guide post 3124 and the second connecting seat 3123. A spacing adjustment shaft 3126 is rotatably mounted on the second connecting seat 3123. Multiple adjusting rings 3127 are provided on the outer side of the spacing adjustment shaft 3126.

[0058] The first connecting seat 3121 and the second connecting seat 3123 are respectively fixedly mounted on two limiting mounting blocks 311. The first connecting seat 3121 is provided with a limiting slot 3122 and two sliding guide posts 3124 are also installed. The end of the sliding guide post 3124 away from the first connecting seat 3121 passes through the second connecting seat 3123, and a third spring 3125 is installed between the sliding guide post 3124 and the second connecting seat 3123. In the initial state, the elastic force generated by the third spring 3125 will push the second connecting seat 3123, so that the second connecting seat 3123 always has a tendency to move closer to the first connecting seat 3121. Since the second connecting seat 3123 is connected to one of the limiting mounting blocks 311, this pushing action will drive the limiting mounting block 311 to move synchronously, so that the two limiting mounting blocks 311 are initially in a relatively close position.

[0059] When the spacing between the two limiting mounting blocks 311 needs to be adjusted to accommodate ultra-thin steel strips 5 of different widths, the operator engages one end of the spacing adjustment shaft 3126 with the adjusting retaining ring 3127 into the limiting groove 3122 of the first connecting seat 3121. Multiple adjusting retaining rings 3127 are provided on the outer side of the spacing adjustment shaft 3126, distributed in segments on the shaft. The position of each retaining ring 3127 corresponds to the spacing of the limiting mounting blocks 311 required for a specific width of ultra-thin steel strip 5. After the spacing adjustment shaft 3126 is engaged with the limiting groove 3122, the pushing action of the third spring 3125 will cause the adjusting retaining ring 3127 to press tightly against the first connecting seat 3121, ensuring that the spacing adjustment shaft 3126 will not easily disengage from the limiting groove 3122 of the first connecting seat 3121 during adjustment, thus guaranteeing the stability of the adjustment. Workers can change the relative position between the second connecting seat 3123 and the first connecting seat 3121 by selecting different positions of the adjusting ring 3127 to cooperate with the limiting groove 3122. Since the second connecting seat 3123 is connected to the limiting mounting block 311, changing the position of the second connecting seat 3123 will cause the connected limiting mounting block 311 to move, thereby adjusting the distance between the two limiting mounting blocks 311.

[0060] See Figures 9 to 10 As shown, the pressing adjustment device 32 includes two pressing blocks 321. Each pressing block 321 has a second limiting groove 3212 on its side. The second limiting groove 3212 is used to connect the synchronous retraction device 33. An assembly guide post is installed between the two pressing blocks 321. The bottom of the two pressing blocks 321 has a limiting docking hole 3211. The limiting docking hole 3211 slides and docks with the synchronous guide post 3115. The bottom of each pressing block 321 has multiple pressing rollers 322.

[0061] The second limiting groove 3212 is used to slide with the synchronous contraction device 33, thereby realizing the installation and movement adjustment of the pressing adjustment tool 32 on the synchronous contraction device 33. An assembly guide post is installed between the two pressing blocks 321, which serves as a connection and guide, ensuring that the two pressing blocks 321 remain stably connected and can slide relative to the assembly guide post. Each pressing block 321 has a limiting docking hole 3211 at its bottom, which slides with the synchronous guide post 3115 on the top of the limiting mounting block 311. This sliding docking method ensures that when the limiting mounting block 311 is moved and adjusted under the action of the spacing adjustment mechanism 312, the pressing block 321 can move synchronously, ensuring that the relative positional relationship between the pressing adjustment tool 32 and the limiting adjustment tool 31 always meets the working requirements. In addition, each pressing block 321 is provided with multiple pressing rollers 322 at its bottom. The pressing rollers 322 are used to contact the top of the ultra-thin steel strip 5 to achieve the pressing action on the ultra-thin steel strip 5.

[0062] After the cutting equipment cuts the ultra-thin steel strip 5, the worker places the cut ultra-thin steel strip 5 into the L-shaped limiting grooves 3111 of the two limiting mounting blocks 311. At this time, the L-shaped limiting grooves 3111 provide initial limiting for the ultra-thin steel strip 5. Simultaneously, the side limiting rollers 3114 on the side of the L-shaped limiting grooves 3111 contact both sides of the ultra-thin steel strip 5, providing lateral limiting for the ultra-thin steel strip 5. Subsequently, the synchronous shrinking device 33 is activated. Since the second limiting slide groove 3212 of the pressing block 321 is slidably connected to the synchronous shrinking device 33, the synchronous shrinking device 33 will drive the pressing block 321 and the limiting mounting blocks 311 to move closer to each other. During the approach process, the pressing roller 322 at the bottom of the pressing block 321 contacts the top of the ultra-thin steel strip 5 and applies downward pressure to the ultra-thin steel strip 5. Through the pushing action of the pressing roller 322 and the limiting action of the L-shaped limiting groove 3111, the ultra-thin steel strip 5 can be stably clamped in the L-shaped limiting groove 3111, thereby achieving the limiting and clamping of the ultra-thin steel strip 5.

[0063] See Figures 4 to 6 As shown, the synchronous contraction device 33 includes two mounting brackets 331 installed on both sides of the limiting adjustment device 31 and the pressing adjustment device 32. The mounting brackets 331 are provided with connecting slide rails, which are slidably connected to the first limiting slide groove 3112 and the second limiting slide groove 3212. The synchronous contraction device 33 also includes two synchronous connecting strips 332 distributed on the limiting mounting block 311 and the pressing block 321. A connecting block 333 is installed between the two synchronous connecting strips 332. A sliding connecting shaft 334 is slidably installed on the connecting block 333. A fourth spring 335 is installed between the sliding connecting shaft 334 and the connecting block 333. A linear driver 336 is also installed on the mounting brackets 331. The output end of the linear driver 336 is connected to the sliding connecting shaft 334.

[0064] Two mounting brackets 331 are respectively installed on both sides of the limiting adjustment device 31 and the pressing adjustment device 32. A connecting slide rail is provided on the mounting bracket 331, which simultaneously slides with the first limiting slide groove 3112 on the side of the limiting mounting block 311 and the second limiting slide groove 3212 on the side of the pressing block 321, thereby realizing the installation and initial movement guidance of the limiting mounting block 311 and the pressing block 321 on the synchronous contraction device 33. A synchronous connecting strip 332 is rotatably connected to both the limiting mounting block 311 and the pressing block 321.

[0065] When it is necessary to synchronously expand the limiting mounting block 311 and the pressing block 321, the linear actuator 336 is activated. The output of the linear actuator 336 drives the sliding connecting shaft 334 to move upward. Since the sliding connecting shaft 334 is connected to the connecting block 333, the rise of the sliding connecting shaft 334 will push the connecting block 333 to rise synchronously. During the rise of the connecting block 333, it will drive the two synchronous connecting strips 332 to expand. Since the synchronous connecting strips 332 are rotatably connected to the limiting mounting block 311 and the pressing block 321 respectively, the expansion movement of the synchronous connecting strips 332 will cause the limiting mounting block 311 and the pressing block 321 to expand synchronously along the connecting slide rail.

[0066] When the limiting mounting block 311 and pressing block 321 need to be retracted, the linear actuator 336 drives the sliding connecting shaft 334 to move downwards. At this time, the fourth spring 335 between the sliding connecting shaft 334 and the connecting block 333 activates, and the elastic force of the fourth spring 335 pushes the connecting block 333 to descend synchronously. The descent of the connecting block 333 drives the two synchronous connecting strips 332 to retract, thereby causing the limiting mounting block 311 and pressing block 321 to retract synchronously along the connecting slide rail. During the retraction process, under the guidance of the synchronous guide post 3115 at the top of the limiting mounting block 311, the pressing adjustment device 32 applies downward pressure to the ultra-thin steel strip 5 through the pressing roller 322 at the bottom of the pressing block 321, while the L-shaped limiting groove 3111 limits the ultra-thin steel strip 5, achieving the limiting clamping of the ultra-thin steel strip 5. Through the elastic pushing of the fourth spring 335, the adaptability of clamping can be effectively improved, ensuring that the limiting clamping function can be stably achieved under different working conditions.

[0067] See Figures 1 to 11 As shown, the laser detection device 4 includes a flow guide frame 41 mounted on the clamping device 3. The flow guide frame 41 is used to fix the laser detector 42. An inclined flow guide plate 411 is provided inside the flow guide frame 41. The inclined flow guide plate 411 is used to guide the air to blow towards the laser detector 42.

[0068] The air guide frame 41 is mounted on the clamping device 3, providing a fixed mounting position for the laser detector 42 and ensuring its stability during the detection process. The laser detector 42 is fixedly mounted on the air guide frame 41, with its detection end facing the surface of the ultra-thin steel strip 5 to be inspected, for laser surface identification detection of the steel strip surface. Because dust and debris easily accumulate at the detection end of the laser detector 42 after long-term use, affecting detection accuracy and effectiveness, it needs to be cleaned regularly. During cleaning, the operator aims the nozzle of the air gun at the inclined air guide plate 411 inside the air guide frame 41 and sprays air. The inclined air guide plate 411 has an inclined angle and a guiding structure. When the airflow is sprayed onto the inclined air guide plate 411, it guides and changes the direction of the airflow, causing it to blow along a preset path towards the detection end of the laser detector 42. This airflow guidance method effectively removes the dust and debris accumulated at the detection end of the laser detector 42, achieving cleaning of the detection end. Furthermore, even when the steel belt is being conveyed and inspected, staff can easily carry out cleaning operations without stopping the machine or disassembling the laser detector 42, which improves the convenience and efficiency of cleaning operations and ensures the long-term stable operation and accuracy of the laser detection device 4.

[0069] Specific working principle:

[0070] Before the cutting operation, the staff adjusts the clamping dimensions of the clamping device 3 according to the dimensions of the ultra-thin steel strip 5 to be cut, ensuring that the clamping area of ​​the clamping device 3 is compatible with the thin steel strip. The clamping device 3 is then adjusted to a suitable position using the movable adjustment device 2. The clamping device 3 can move adaptively at multiple angles at the adjustment end of the movable adjustment device 2.

[0071] After the cutting equipment cuts the ultra-thin steel strip 5, the worker passes the cut ultra-thin steel strip 5 through the misalignment guide frame 1. The misalignment guide frame 1 guides the cut ultra-thin steel strip 5 in a misaligned manner, so that the two ultra-thin steel strips 5 pass through their respective misalignment guide frames 1. Subsequently, the ultra-thin steel strip 5 passes through the clamping device 3 and connects to the steel coil winding device, completing the installation of the steel strip. At this time, the laser detector 42 on the clamping device 3 is in a ready-to-inspection state, preparing to inspect the cut surface of the ultra-thin steel strip 5.

[0072] The cutting equipment continuously cuts the ultra-thin steel strip 5, while the coil winding device winds it up, allowing it to continuously pass through the clamping device 3. Due to the thinness of the ultra-thin steel strip 5, the tension during winding is limited to prevent deformation, causing slight deviation during its movement. When this deviation occurs, the clamping device 3 and the movable adjustment device 2 work together to adaptively adjust the displacement based on the deviation. The clamping device 3 always moves synchronously with the ultra-thin steel strip 5, ensuring that the laser detector 42 maintains a relative position with the cut surface of the ultra-thin steel strip 5, thus ensuring accurate detection. The laser detector 42 performs real-time detection of the cut surface of the ultra-thin steel strip 5. Once an abnormality is detected in the cut surface contour of the ultra-thin steel strip 5, it is determined that burrs have appeared during the cutting process, triggering an alarm signal to prompt maintenance of the cutting equipment.

[0073] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
