[0002] Traditional motors often use non-oriented silicon steel materials to manufacture rotors, which are limited by properties such as high coercivity and high conductivity when running at high frequencies, resulting in low efficiency. Amorphous materials that have emerged in recent years have higher resistivity and permeability, as well as smaller coercivity and core loss. Among them, amorphous alloy materials, also known as metallic glass or liquid metal, are a new generation of green and environmentally friendly high-performance metal materials with excellent properties such as high strength, high hardness, corrosion resistance, superplasticity and soft magnetism. The soft magnetic amorphous alloys that have been applied to actual electrodes are iron-based amorphous alloys.

[0003] At present, amorphous alloy strips are usually used to manufacture components in important fields such as high-performance motors, transformers and sensors, and their surface flatness requirements are very strict. In the production process of amorphous alloy strips, surface flatness detection is crucial to ensure product quality.

DETAILED DESCRIPTION

[0039] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0040] Embodiment 1: According to the attached Figure 1 To Attachment Figure 2As shown, a surface flatness detection device for amorphous alloy strip production is used to detect the flatness of the surface of the amorphous alloy strip, which includes a device body 100, the device body 100 includes a base 101, and a frame 102 is installed on the base 101, and connecting frames 103 are provided on both the upper and lower sides of the amorphous alloy strip, and the connecting frames 103 are installed on the frame 102, and a controller 104 is also installed on the frame 102. Among them, a reeling device 105 and a reeling device 107 are provided on the frame 102, and a first motor 106 is provided on the reeling device 105, and a second motor 108 is provided on the reeling device 107, so as to control the rotation of the first motor 106 and the second motor 108 to control the reeling device 105 and the reeling device 107 to rotate.

[0041] It should be understood that when the surface flatness of the amorphous alloy strip is detected, the controller 104 drives the first motor 106 and the second motor 108 to rotate, and controls the unwinding device 105 and the winding device 107 to unwind and wind the amorphous alloy strip.

[0042] Furthermore, the frame 102 is connected to bearings with a first pressure roller 109, a first support roller 110, a second pressure roller 111, a second support roller 112 and a third pressure roller 113. The number of the first support rollers 110 and the second support rollers 112 are respectively set to two groups, and the two groups of first support rollers 110 and the two groups of second support rollers 112 are respectively set symmetrically, thereby 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. In other words, 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 Attachment Figure 5 As shown, both detection tables are provided with a first detection unit 200, which performs contact detection on the upper and lower surfaces of the amorphous alloy strip and performs pre-detection processing on the amorphous alloy strip. The first detection unit 200 includes a fixed plate 201 mounted on the frame 102, and a pressure sensor 202 is installed on one side of the fixed plate 201 close to the detection table, and a detection head 203 is provided on the pressure sensor 202.

[0045] The pressure sensor 202 may be a piezoresistive pressure sensor 202. The piezoresistive pressure sensor 202 is a resistive pressure sensor 202 that works by utilizing 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 provided on the detection head 203, and two groups of detection plates 204 are provided on each detection area. A detection gasket 205 is provided on the side where each two groups of detection plates 204 are close to each other, and a pressing plate 206 is provided on the side where the detection gasket 205 is close to each other. The pressing plate 206 is fixedly connected to the detection plate 204, and there are multiple pressing plates 206 on each side, and a convex pad 207 is installed on the side where the multiple pressing plates 206 are close to the detection gasket 205.

[0047] It should be understood that when the pressing sheet 206 is squeezed and deformed, the pressing sheet 206 drives the convex pad 207 to move, and the pressing sheet 206 transmits the pressure to the detection pad 205. When pressure is applied to the detection pad 205 on the piezoresistive pressure sensor 202, the material of the detection pad 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, the detection gasket 205 is provided with stress-bearing areas corresponding to the multiple pressing plates 206. Through the setting of the multiple pressing plates 206, the convex pads 207 on the different pressing plates 206 are driven to squeeze the detection gasket 205, so that the stress-bearing area is compressed and the signal is sent to the controller 104. The controller 104 controls the second detection unit 300 according to the position of the stress-bearing area, so as to facilitate the determination of the position of the pressing plate 206 where the defect on the amorphous alloy strip is located.

[0049] Furthermore, according to the attached Figure 5 To Attachment Figure 8 As shown, a pressure head 208 is provided between the two groups of pressure sheets 206, and a movable arm 209 is installed on the pressure head 208. A bracket 210 is also installed on the fixed plate 201, and a movable shaft is connected to the 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 through 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, and the end of the movable arm 209 away from the pressure head 208 is rotatably connected to the contact wheel 211 through a bearing.

[0050] It should be noted that when there is a depression on the surface of the amorphous alloy strip, the contact wheel 211 contacts the surface of the amorphous alloy strip, and uses the convex or concave features of the unevenness to drive the contact wheel 211 to rotate with the movable axis as the center of the circle, so that the movable arm 209 drives the pressure head 208 to move synchronously, so that the pressure head 208 contacts the pressing sheet 206, and the uneven position on the amorphous alloy strip is physically pre-positioned. In addition, the first torsion spring is provided to facilitate the driving of the movable arm 209 to reset.

[0051] According to the attached Figure 4 As shown, two groups of support platforms are provided on the side of the detection table away from the fixed plate 201, and the support platforms correspond to the positions 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. Each two groups of connecting rollers 212 are provided with transmission belts 213 for stably supporting the detection area of ​​the amorphous alloy strip.

[0052] It should be noted that the transmission belt 213 is made of 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 roller 212, thereby driving the connecting roller 212 to rotate, so that the transmission belt 213 can 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 in the transmission belt 213, and the third support rollers 214 are rotatably connected to the frame 102 through bearings, and a pad 215 is provided between each two groups of third support rollers 214; in this embodiment, the transmission belt 213 is supported by the arrangement of the third support rollers 214 and the pads 215, so as to facilitate the support of the detection surface of the amorphous alloy strip and ensure the accuracy of the detection data.

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

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

[0056] Furthermore, according to the attached Fig. 9 As shown, a first screw rod 303 is connected to a 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 visual detector 302, and 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 303 is controlled to rotate, and the first screw 303 and the first sleeve 304 are threadedly connected, so that the second flatness visual 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] In addition, a guide rod 306 is installed on the frame 102, and a guide sleeve 307 is slidably connected to the guide rod 306, and the guide sleeve 307 is fixedly connected to the second visual flatness detector 302. In this embodiment, the movement of the second visual flatness detector 302 is limited by the arrangement of the guide rod 306 and the guide sleeve 307, so that the second visual flatness detector 302 can be linearly moved outside the guide rod 306 through the guide sleeve 307.

[0059] In addition, according to the attached Figure 1 To Attachment Fig. 9 As shown, when new defects that have never appeared in the sample appear in the amorphous alloy strip during the flatness detection process, the target detection algorithm may not be able to effectively identify these new defects, which may easily lead to missed detection, resulting in the uneven items flowing directly 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 is used to re-inspect the amorphous alloy strip and the suspicious position, which can effectively avoid missed detection, thereby improving the detection efficiency and the yield rate.

[0060] According to the attached Figure 3 and attached Fig.10As shown, the frame 102 is also provided with an edge flatness correction unit 400, which includes a feed roller 401 located below the amorphous alloy strip, the feed roller 401 is connected to the frame 102 bearing, and a movable column 402 located on the upper and lower sides of the amorphous alloy strip, the movable column 402 is slidably connected to the inside of the frame 102, and a traction roller 403 is installed on the movable column 402. In this embodiment, the amorphous alloy strip in the conveying process is guided by the feed roller 401, and the axial offset of the amorphous alloy strip is detected. When the amorphous alloy strip has an axial offset, the traction roller 403 is used to traction and correct the position of the amorphous alloy strip, so that when the amorphous alloy strip is wound into a coil, the two axial end faces of the amorphous alloy strip can be kept flat, avoiding the problem of uneven end faces.

[0061] Among them, according to the attached Fig.11 and attached Fig.13 As shown, two groups of adjusting sleeves 404 are slidably connected to the feed roller 401, and a detection plate 405 is provided on the adjacent side of the adjusting sleeves 404, an oil chamber 406 is provided in the adjusting sleeves 404, and a piston block 407 is slidably connected in the oil chamber 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 plate 405, a first connecting oil pipe 409 is installed on the adjusting sleeve 404, and the first connecting oil pipe 409 is communicated with the inside of the oil chamber 406.

[0062] In addition, a first connecting seat 410 is symmetrically provided in the frame 102, and a traction arm 411 is rotatably connected to the first connecting seat 410 through 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, and a movable groove 412 is symmetrically opened on the traction arm 411, and a movable rod 413 is slidably connected in the movable groove 412, one group of movable rods 413 are installed with second connecting seats 414 at both ends close to the movable column 402, and the second connecting seat 414 is rotatably connected to the movable column 402 through a bearing, and a hydraulic cylinder 415 is also symmetrically provided in the frame 102, and a hydraulic rod 416 is provided in the hydraulic cylinder 415, and the hydraulic rod 416 is fixedly connected to another group of movable rods 413, and 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 thing is that two groups of hoses 418 are provided between the first connecting oil pipe 409 and the second connecting oil pipe 417, and the two groups of hoses 418 are cross-arranged, and the head and tail ends of the hoses 418 are respectively connected to the intersecting first connecting oil pipe 409 and the second connecting oil pipe 417. Through the setting of the hoses 418, the first connecting oil pipe 409 and the second connecting oil pipe 417 at the diagonal position are connected.

[0064] It should be understood that when the amorphous alloy strip undergoes axial displacement, the amorphous alloy strip moves on the feed roller 401, squeezing a group of detection plates 405 located in the moving direction, causing the detection plates 405 to be displaced synchronously, driving the piston rod 408 to move, causing 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 hydraulic rod 416 to move in the hydraulic cylinder 415, driving the traction arm 411 to move, and connecting with the traction arm 411 shaft through the first connecting seat 410, driving the movable column 402 to slide axially in the frame 102, so that the amorphous alloy strip is pulled by the traction roller 403, and the axial position of the amorphous alloy strip is corrected to avoid the problem of uneven end surface.

[0066] It should be noted that during the conveying process, the amorphous alloy strip will be axially offset on the feed roller 401. There are two situations of this axial offset. One is that the amorphous alloy strip is offset to the left, and the other is that the amorphous alloy strip is offset to the right. When the amorphous alloy strip is offset to the left, the traction roller 403 is driven to pull the amorphous alloy strip to the right. When the amorphous alloy strip is offset 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 Fig.10 and attached Fig.11 As shown, the frame 102 is connected to a second screw rod 419 by a bearing, and the second screw rod 419 is threadedly connected to a second screw sleeve 420, and the second screw sleeve 420 is fixedly connected to the adjustment sleeve 404. Wherein, the second screw rod 419 is a bidirectional threaded rod. In other words, the threads on both sides of the second screw rod 419 are arranged oppositely. When the second screw rod 419 is controlled to rotate, the second screw sleeve 420 moves closer to or away from each other, and one end of the second screw rod 419 penetrates the frame 102 and is equipped with a crank. In this embodiment, the staff rotates the crank to control the second screw rod 419 to rotate, and the second screw rod 419 and the second screw sleeve 420 are threadedly connected to control the two groups of adjustment sleeves 404 to move closer to or away from each other, thereby adjusting the distance between the adjustment sleeves 404.

[0068] Embodiment 2: According to the attached Figure 1 To Attachment Fig.13 As shown, a method for detecting surface flatness of an amorphous alloy strip for production, using a surface flatness detection device for production of an amorphous alloy strip as provided in Example 1, comprises the following steps:

[0069] Step 1: Loading;

[0070] The amorphous alloy strip is loaded onto the unwinding device 105, and 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 then the amorphous alloy strip is connected to the winding device 107;

[0071] Step 2: Pre-detection;

[0072] The first detection unit 200 is used to perform contact detection on the upper and lower surfaces of the amorphous alloy strip to physically pre-position the uneven positions on the amorphous alloy strip;

[0073] Step 3: Supplementary testing;
