Description

Technical Field

[0001] The present invention relates to the technical field of flatness detection, and more specifically, it relates to a surface flatness detection device and method for the production of amorphous alloy strips. Background Art

[0002] Traditional motors often use non-oriented silicon steel materials to manufacture rotors. When operating at high frequencies, they are limited by properties such as high coercivity and high conductivity, resulting in low efficiency. In recent years, emerging amorphous materials have higher resistivity and magnetic permeability, as well as smaller coercivity and core loss. Among them, amorphous alloy materials, also known as metallic glasses or liquid metals, are a new generation of green and environmentally friendly high-performance metallic materials with excellent properties such as high strength, high hardness, corrosion resistance, superplasticity, and soft magnetism. Currently, the soft magnetic amorphous alloy applied to actual electrodes is the iron-based amorphous alloy.

[0003] Currently, amorphous alloy strips are usually used to manufacture components in important fields such as high-performance motors, transformers, and sensors, and the requirements for their surface flatness are very strict. During the production process of amorphous alloy strips, the detection of surface flatness is crucial for ensuring product quality. Moreover, an efficient and accurate surface flatness detection device can improve production efficiency, reduce production costs, and guarantee product quality.

[0004] When detecting the flatness of amorphous alloy strips, visual inspection of the surface of the amorphous alloy strips is required. Due to the special properties of the strip surface, such as smoothness and reflectivity, local reflection phenomena are likely to occur. These reflective areas may cause occlusion or interference in visual inspection, resulting in missed detections or misjudgments, thus affecting the detection efficiency and increasing the product defect rate. Summary of the Invention

Specific Embodiments

[0039] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein, and the functions and arrangements of the elements discussed can be changed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0040] Example 1: According to the attached Figure 1 to the attached Figure 2As shown in the figure, a surface flatness detection device for the production of amorphous alloy strips is used to detect the flatness of the surface of amorphous alloy strips. It includes a device body 100, and the device body 100 includes a base 101, and a frame 102 is installed on the base 101. Connecting frames 103 are provided on both the upper and lower sides of the amorphous alloy strip, and the connecting frames 103 are all installed on the frame 102. A controller 104 is also installed on the frame 102. Among them, a unwinding device 105 and a winding device 107 are provided on the frame 102. A first motor 106 is provided on the unwinding device 105, and a second motor 108 is provided on the winding device 107 to control the rotation of the unwinding device 105 and the winding device 107 by controlling the rotation of the first motor 106 and the second motor 108.

[0041] It should be understood that when detecting the surface flatness of the amorphous alloy strip, the first motor 106 and the second motor 108 are driven to rotate through the controller 104 to control the unwinding device 105 and the winding device 107 to perform unwinding and winding operations on the amorphous alloy strip.

[0042] Furthermore, a first pressing roller 109, a first supporting roller 110, a second pressing roller 111, a second supporting roller 112, and a third pressing roller 113 are connected to the frame 102 by bearings. The numbers of the first supporting roller 110 and the second supporting roller 112 are respectively set to two groups, and the two groups of first supporting rollers 110 and the two groups of second supporting rollers 112 are symmetrically arranged, thus forming a detection table for the movement of the amorphous alloy strip.

[0043] Specifically, one end of the amorphous alloy strip is connected to the unwinding device 105, and the other end of the amorphous alloy strip passes through the first pressing roller 109, the first supporting roller 110, the second pressing roller 111, the second supporting roller 112, and the third pressing roller 113 and is connected to the winding device 107. That is to say, when the unwinding device 105 and the winding device 107 are working, the amorphous alloy strip moves on the surfaces of the first pressing roller 109, the first supporting roller 110, the second pressing roller 111, the second supporting roller 112, and the third pressing roller 113.

[0044] According to the attached Figure 3 to the attached Figure 5 As shown in the figure, a first detection unit 200 is provided on both detection tables. The first detection unit 200 performs contact detection on the upper and lower surfaces of the amorphous alloy strip to perform pre-detection processing on the amorphous alloy strip. The first detection unit 200 includes a fixing plate 201 installed on the frame 102. A pressure sensor 202 is installed on the side of the fixing plate 201 close to the detection table, and a detection head 203 is provided on the pressure sensor 202.

[0045] Among them, the pressure sensor 202 can be a piezoresistive pressure sensor 202. The piezoresistive pressure sensor 202 is a resistive pressure sensor 202 that works based on the piezoresistive effect of semiconductor materials. The piezoresistive effect refers to the phenomenon that the resistance of semiconductor materials changes under pressure.

[0046] Specifically, two groups of detection areas are symmetrically arranged on the detection head 203, and two groups of detection plates 204 are arranged on each detection area. On the side where each two groups of detection plates 204 are close to each other, detection gaskets 205 are provided. On the side where the detection gaskets 205 are close to each other, pressing sheets 206 are provided. The pressing sheets 206 are fixedly connected to the detection plates 204. There are multiple pressing sheets 206 on each side, and convex pads 207 are installed on the side of the multiple pressing sheets 206 close to the detection gaskets 205.

[0047] It should be understood that when the pressing sheet 206 is deformed by extrusion and the pressing sheet 206 drives the convex pad 207 to move, the pressing sheet 206 transmits the pressure to the detection gasket 205. When pressure is applied to the detection gasket 205 of the piezoresistive pressure sensor 202, the material of the detection gasket 205 will deform, thereby causing a change in its resistance. By measuring the change in resistance, the applied pressure can be determined.

[0048] In addition, force-bearing areas corresponding to the multiple pressing sheets 206 are arranged on the detection gasket 205. Through the arrangement of the multiple pressing sheets 206, the convex pads 207 on different pressing sheets 206 are driven to extrude the detection gasket 205, so that the force-bearing areas are pressed, and a signal is sent to the controller 104. The controller 104 controls the second detection unit 300 according to the position of the force-bearing area, so as to facilitate determining the position of the pressing sheet 206 where the defect on the amorphous alloy strip is located.

[0049] Further, according to the attached Figure 5 to the attached Figure 8 As shown, a pressing head 208 is provided between the two groups of pressing sheets 206, and a movable arm 209 is installed on the pressing head 208. The fixing plate 201 is also provided with a bracket 210, and a movable shaft is connected by a bearing in the bracket 210; there are several groups of movable arms 209, and each group of movable arms 209 is rotatably connected to the movable shaft by a bearing. A first torsion spring is installed between the movable arm 209 and the bracket 210, and the first torsion spring is located outside the movable shaft. The end of the movable arm 209 far from the pressing head 208 is rotatably connected to a contact wheel 211 by a bearing.

[0050] It should be noted that when there are depressions on the surface of the amorphous alloy strip, the contact wheel 211 contacts the surface of the amorphous alloy strip. By utilizing the convex or concave features of the uneven areas, the contact wheel 211 is driven to rotate around the movable axis, so that the movable arm 209 drives the indenter 208 to move synchronously, making the indenter 208 contact the pressing piece 206, and physically pre-positioning the uneven positions on the amorphous alloy strip. Moreover, through the setting of the first torsion spring, it is convenient to drive the movable arm 209 to reset.

[0051] According to the appendix Figure 4 As shown, on the side of the detection table away from the fixed plate 201, there are two groups of support platforms, and the positions of the support platforms correspond to those of the contact wheels 211. The support platforms include two groups of connecting rollers 212, and the connecting rollers 212 are rotatably connected to the frame 102 through bearings. A transmission belt 213 is provided on each two groups of connecting rollers 212 for stably supporting the detection area of the amorphous alloy strip.

[0052] It should be noted that the material of the transmission belt 213 is rubber. When the amorphous alloy strip is in a moving state, the amorphous alloy strip can drive the transmission belt 213 to move outside the connecting rollers 212, thereby driving the connecting rollers 212 to rotate, so as to support the amorphous alloy strip during the movement of the amorphous alloy strip.

[0053] Among them, a plurality of third support rollers 214 are provided inside the transmission belt 213, and the third support rollers 214 are rotatably connected to the frame 102 through bearings. A backing plate 215 is also provided between each two groups of third support rollers 214; in this embodiment, through the setting of the third support rollers 214 and the backing plate 215, the transmission belt 213 is supported, which is convenient for supporting the detection surface of the amorphous alloy strip and ensuring the accuracy of the detection data.

[0054] According to the appendix Figure 3 and the appendix Figure 9 As shown, second detection units 300 are provided on both the upper and lower sides of the amorphous alloy strip. The second detection units 300 include a first flatness vision detector 301 and a second flatness vision detector 302 provided on both the upper and lower sides of the amorphous alloy strip. The first flatness vision detector 301 is installed on the connecting frame 103. Among them, the first flatness vision detector 301 and the second flatness vision detector 302 adopt a metal surface flatness detector to detect various defects on the amorphous alloy strip, including various flaws such as cracks, scratches, and dents on the material surface. By detecting the cracks, scratches, and dents on the material surface, it is convenient to comprehensively test the flatness of the surface of the amorphous alloy strip.

[0055] When the force-receiving area on the detection gasket 205 is compressed and a signal is sent to the controller 104, the second flatness vision detector 302 is controlled to move so that the second flatness vision detector 302 moves to a position corresponding to the force-receiving area, thereby facilitating local key detection of the surface of the amorphous alloy strip.

[0056] Further, as shown in the attached Figure 9 figures, a first screw rod 303 is connected to the bearing on the frame 102, and a first screw sleeve 304 is threadedly connected to the first screw rod 303. The first screw sleeve 304 is fixedly connected to the second flatness vision detector 302. A third motor 305 is also installed on the frame 102, and the output shaft of the third motor 305 is fixedly connected to the first screw rod 303.

[0057] It should be noted that when the third motor 305 is driven to rotate, the first screw rod 303 is controlled to rotate. Through the threaded connection between the first screw rod 303 and the first screw sleeve 304, the second flatness vision detector 302 can be driven to move so that it corresponds to the position of the pressing sheet 206, thereby facilitating local key detection of the amorphous alloy strip and avoiding the problem of missed detection.

[0058] Moreover, a guide rod 306 is also installed on the frame 102, and a guide sleeve 307 is slidably connected to the guide rod 306. The guide sleeve 307 is fixedly connected to the second flatness vision detector 302. In this embodiment, through the arrangement of the guide rod 306 and the guide sleeve 307, the movement of the second flatness vision detector 302 is limited, thereby facilitating the second flatness vision detector 302 to linearly move outside the guide rod 306 through the guide sleeve 307.

[0059] In addition, as shown in the attached Figure 1 to the attached Figure 9 figures, during the flatness detection process, when new defects that have never appeared in the samples occur in the amorphous alloy strip, the target detection algorithm may not be able to effectively identify these new defects, thus easily resulting in missed detection and causing uneven items to directly flow into the next process. In this embodiment, by combining the first detection unit 200 and the second detection unit 300, the amorphous alloy strip is pre-detected by the first detection unit 200, the pressure sensor 202 sends a signal to the controller 104 for the suspicious position, and the second detection unit 300 re-checks the amorphous alloy strip and the suspicious position, which can effectively avoid the phenomenon of missed detection, thereby improving the detection efficiency and the yield rate.

[0060] According to the attached Figure 3 and the attached Figure 10As shown, an edge flatness correction unit 400 is further provided on the frame 102. The edge flatness correction unit 400 includes a feeding roller 401 located below the amorphous alloy strip. The feeding roller 401 is connected to the frame 102 by bearings, and movable columns 402 located on the upper and lower sides of the amorphous alloy strip. The movable columns 402 are slidably connected to the inside of the frame 102, and a traction roller 403 is installed on the movable columns 402. In this embodiment, the feeding roller 401 guides the amorphous alloy strip during transportation and detects the axial offset of the amorphous alloy strip. When the amorphous alloy strip generates an axial offset, the position of the amorphous alloy strip is traction-corrected by the traction roller 403, so that when the amorphous alloy strip is wound into a roll, the two end faces in the axial direction of the amorphous alloy strip can be kept flat, avoiding the problem of uneven end faces.

[0061] Among them, according to the attached Figure 11 and the attached Figure 13 As shown, two sets of adjusting sleeves 404 are slidably connected to the feeding roller 401, and detection plates 405 are provided on the closer sides of the adjusting sleeves 404. An oil cavity 406 is provided in the adjusting sleeve 404, and a piston block 407 is slidably connected in the oil cavity 406. A plurality of piston rods 408 are installed on the piston block 407, and the piston rods 408 are fixedly connected to the detection plates 405. A first connecting oil pipe 409 is installed on the adjusting sleeve 404, and the first connecting oil pipe 409 is connected to the inside of the oil cavity 406.

[0062] In addition, first connecting seats 410 are symmetrically provided in the frame 102, and a traction arm 411 is rotatably connected to the first connecting seat 410 by a rotating shaft. A second torsion spring is installed between the traction arm 411 and the first connecting seat 410, and the second torsion spring is located outside the rotating shaft. Movable slots 412 are symmetrically formed in the traction arm 411, and movable rods 413 are slidably connected in the movable slots 412. Second connecting seats 414 are installed at both ends of one group of movable rods 413 close to the movable column 402, and the second connecting seats 414 are rotatably connected to the movable column 402 by bearings. Hydraulic cylinders 415 are also symmetrically provided in the frame 102, and hydraulic rods 416 are provided in the hydraulic cylinders 415. The hydraulic rods 416 are fixedly connected to the other group of movable rods 413. A second connecting oil pipe 417 is installed on the hydraulic cylinder 415, and the second connecting oil pipe 417 is connected to the inside of the hydraulic cylinder 415.

[0063] The same is that two sets of hoses 418 are provided between the first connecting oil pipe 409 and the second connecting oil pipe 417, and the two sets of hoses 418 are arranged in a cross shape. The head and tail ends of the hoses 418 are respectively connected to the intersecting first connecting oil pipe 409 and second connecting oil pipe 417. Through the arrangement of the hoses 418, the first connecting oil pipe 409 and the second connecting oil pipe 417 at the diagonal positions are connected.

[0064] It should be understood that when the amorphous alloy strip has an axial displacement, the amorphous alloy strip moves on the feeding roller 401, squeezes a group of detection plates 405 in the moving direction, causes the detection plates 405 to generate displacements synchronously, drives the piston rod 408 to move, and causes the piston block 407 to move synchronously in the oil chamber 406, squeezing the hydraulic oil in the oil chamber 406.

[0065] When the hydraulic oil in the oil chamber 406 is squeezed, the hydraulic oil is transmitted to the hydraulic cylinder 415 through the hose 418, thereby controlling the movement of the hydraulic rod 416 in the hydraulic cylinder 415, driving the traction arm 411 to move, being rotationally connected to the traction arm 411 through the first connecting seat 410, driving the movable column 402 to axially slide in the frame 102, causing the amorphous alloy strip to be pulled by the traction roller 403, and correcting the axial position of the amorphous alloy strip to avoid the problem of uneven end faces.

[0066] It should be noted that during the conveying process of the amorphous alloy strip, it will have an axial offset on the feeding roller 401. This axial offset has two situations. One is that the amorphous alloy strip deflects to the left, and the other is that the amorphous alloy strip deflects to the right. When the amorphous alloy strip deflects to the left, the traction roller 403 is driven to pull the amorphous alloy strip to the right. When the amorphous alloy strip deflects to the right, the traction roller 403 is driven to pull the amorphous alloy strip to the left, thereby completing the flatness correction of the end face of the amorphous alloy strip.

[0067] According to the attached Figure 10 and the attached Figure 11 As shown, a second screw rod 419 is connected to the frame 102 by bearings, and a second screw sleeve 420 is threadedly connected to the second screw rod 419. The second screw sleeve 420 is fixedly connected to the adjusting sleeve 404. Among them, the second screw rod 419 is a bidirectional screw rod. That is to say, the threads on both sides of the second screw rod 419 are arranged in the opposite direction. When the second screw rod 419 is controlled to rotate, the second screw sleeves 420 move closer to or away from each other. One end of the second screw rod 419 passes through the frame 102 and is equipped with a crank. In this embodiment, by the staff rotating the crank, the second screw rod 419 is controlled to rotate. Through the threaded connection between the second screw rod 419 and the second screw sleeve 420, the two groups of adjusting sleeves 404 are controlled to move closer to or away from each other, thereby adjusting the distance between the adjusting sleeves 404.

[0068] Embodiment 2: According to the attached Figure 1 to the attached Figure 13 As shown, a method for detecting the surface flatness of an amorphous alloy strip during production uses a device for detecting the surface flatness of an amorphous alloy strip during production provided in Embodiment 1, and includes the following steps:

[0069] Step 1: Loading

[0070] Load the amorphous alloy strip onto the unwinding device 105, and pass the amorphous alloy strip through the first pressure roller 109, the first support roller 110, the second pressure roller 111, the second support roller 112 and the third pressure roller 113. Subsequently, connect the amorphous alloy strip to the winding device 107;

[0071] Step 2: Pre-detection
