Description

Technical Field

[0001] This invention relates to the field of detection device technology, and in particular to a detection device for amorphous ribbon. Background Technology

[0002] Amorphous ribbons, with their unique amorphous structure, possess excellent magnetic and electrical properties, and their manufacturing primarily employs single-roll melt rapid quenching technology. However, fluctuations in temperature, flow rate, or cooling rate during this process can lead to defects such as uneven thickness, voids, and surface damage; these defects not only affect the appearance of the amorphous ribbon but also its electromagnetic properties. Therefore, high requirements are placed on product quality inspection during the production of amorphous ribbons.

[0003] Currently, in the inspection of amorphous ribbons, thickness measurement is mainly achieved through thickness gauges; while surface defects are detected and eliminated by applying tension to the amorphous ribbon using a folding structure, causing the amorphous ribbon to break at weak points such as holes, and expanding the defects.

[0004] However, both thickness measurement and tension-based surface defect detection have similar shortcomings. First, the measurement speed is generally slow, making it difficult to match the efficient production rhythm. Second, and more importantly, these methods cannot continuously inspect strip materials, resulting in: one, minor or distributed defects are easily missed, affecting product quality control; two, the inspection rhythm is difficult to synchronize with the production process, causing operational chaos and ultimately reducing overall inspection efficiency. Summary of the Invention

[0010] Furthermore, the device also includes two sets of positioning components disposed opposite each other within the main frame, through which the amorphous ribbon passes, for stably clamping the amorphous ribbon during the marking process and preventing its displacement;

[0011] The positioning components include: an electric pusher fixedly connected within the main frame; and a clamping frame fixedly connected to the output end of the electric pusher, through which the amorphous ribbon passes; the surface of the clamping frame in contact with the amorphous ribbon is provided with friction texture to increase friction.

[0012] Furthermore, the device also includes: a buffer component disposed within the main frame, used to buffer the displacement segment of the amorphous strip caused by continuous conveying when the positioning component clamps the amorphous strip;

[0013] The buffer assembly includes: a mounting bracket fixedly connected to both sides inside the main frame; a guide shaft rotatably connected between the tops of the two sets of mounting brackets; an adjusting bracket slidably connected between the mounting brackets, with the difference between the number of guide shafts and the number of adjusting brackets being one; an adjusting shaft rotatably connected to the adjusting bracket; and a return spring sleeved on the mounting bracket, with its two ends fixed to the mounting bracket and the adjusting bracket respectively.

[0014] Furthermore, the device also includes a cleaning component located within the main frame, used to remove impurities adhering to the surface of the amorphous ribbon, preventing them from being misjudged as surface defects;

[0015] The cleaning components include: a mounting frame fixedly connected within the main frame, symmetrically structured vertically with an air inlet slot in the middle through which the amorphous ribbon passes; collection chambers inserted into the upper and lower sides of the mounting frame for collecting impurities; both the collection chambers and the mounting frame have interfaces for communication; the collection chambers have exhaust vents and internal filters for discharging airflow and trapping impurities; a guide duct fixedly connected within the mounting frame, connecting the air inlet slot to the interface on the mounting frame; two sets of mounting pipes fixedly connected to the mounting frame, corresponding to the positions of the collection chambers on both sides; at least two impellers rotatably connected to each mounting pipe, located at the inlets of the guide ducts, whose rotation generates directional airflow to adsorb impurities on the surface of the amorphous ribbon; a drive shaft rotatably connected within each mounting pipe; a bevel gear set consisting of two mutually perpendicular meshing bevel gears located between each drive shaft and its corresponding impeller for power transmission; and a second motor fixedly connected to the mounting frame, its output end connected to the drive shaft.

Detailed Implementation

[0035] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0036] Example: A detection device for amorphous ribbon, see reference. Figures 1-4 It includes: a main frame 01, which adopts a long frame structure to provide installation space, through which the amorphous ribbon is conveyed by a roller conveyor and stably passes through the main frame 01 from front to back; the main frame 01 is equipped with a control unit that integrates a control module and a signal module for controlling the operation of the device; and two sets of detection components mounted opposite each other in the main frame 01, through which the amorphous ribbon passes, so that the upper and lower surfaces of the amorphous ribbon can be detected simultaneously for thickness changes and surface defects.

[0037] The detection components include: a mounting shaft 02 fixedly installed within the main frame 01; a bracket 03 fixedly installed on the mounting shaft 02; a vision camera 04 fixedly installed on the bracket 03, which establishes a signal connection with the control unit to capture the surface features of the amorphous ribbon and convert them into data information, which is then sent to the control unit for comparison and defect location; a rotating arm 05 rotatably installed on the mounting shaft 02; a vertical shaft 06 fixedly installed on the rotating arm 05; a roller 07 rotatably installed at the end of the vertical shaft 06, which makes rolling contact with the amorphous ribbon to reduce wear; a reset torsion spring 08 fitted on the mounting shaft 02, with its two ends fixed to the rotating arm 05 and the mounting shaft 02 respectively; and a sensor 09 fixedly installed on the mounting shaft 02, which establishes a signal connection with the control unit to detect the rotation angle of the rotating arm 05 and send the angle data to the control unit. The rotating arm 05, vertical shaft 06, roller 07, reset torsion spring 08, and sensor 09 together constitute a detection subgroup. The mounting shaft 02 has a row of detection subgroups along its axial direction. The more subgroups there are, the higher the detection accuracy.

[0038] The amorphous ribbon passes between two sets of detection components, attaches to the roller 07, and is twisted by the reset torsion spring 08. The sensor 09 records the initial angle of the rotating arm 05 in this state. When the roller conveyor drives the amorphous ribbon to move, the roller 07 rolls along its surface, and the vision camera 04 records the surface morphology and transmits the data to the control unit to realize the identification and location of surface defects. If the thickness of the amorphous ribbon changes, the rotating arm 05 will be twisted, the sensor 09 detects the angle change and records the abnormal thickness position. After the thickness returns to normal, the reset torsion spring 08 drives the rotating arm 05 to reset. The densely arranged detection sub-groups can realize precise positioning and quantitative analysis, improve detection accuracy and the comprehensiveness of defect identification. The whole process is completed synchronously in continuous conveying, and the detection rhythm can be consistent with the production process, which helps to improve detection efficiency.

[0039] This device achieves simultaneous online detection of thickness and surface defects in amorphous ribbon and real-time accurate location of defects through the coordinated operation of vision camera 04, detection sub-assembly and sensor 09. The overall structure is comprehensive and the response is sensitive, which will comprehensively improve the detection coverage and efficiency of this device, as well as enhance its adaptability to high-speed production.

[0040] See Figure 1 , Figure 2 and Figure 5 The device also includes two sets of marking components mounted opposite each other in the main frame 01, through which the amorphous ribbon passes, for direct and intuitive marking on the surface of the amorphous ribbon while recording defect data, which facilitates subsequent positioning and processing operations. The marking components are located behind the detection components.

[0041] The upper and lower side walls of the main frame 01 are provided with sliding grooves 10a, and two sets of marking components are provided on the two sides of the sliding grooves 10a. Each set of marking components includes: an engraving machine 10 slidably installed in the sliding groove 10a, which establishes a signal connection with the control unit; an adjusting screw 11 rotatably installed in the main frame 01, whose direction is parallel to the sliding groove 10a and is threadedly engaged with the engraving machine 10; and a first motor 12 fixedly installed on the main frame 01, whose output end is coaxially fixed with the adjusting screw 11 and establishes a signal connection with the control unit.

[0042] Based on the transport speed of the amorphous ribbon and the spacing between the marking component and the detection component, the control unit sets the corresponding delay parameters of the engraving machine 10 and the running speed of the first motor 12. When the detection component detects a defect, it immediately sends a signal to the first motor 12 to drive the engraving machine 10 to move to the corresponding lateral position and completes the positioning before the amorphous ribbon moves to the marking station. When the amorphous ribbon arrives at the marking position, the engraving machine 10 starts according to the preset delay and achieves accurate marking on the surface of the amorphous ribbon.

[0043] This device uses a marking component and a control unit for electromechanical linkage and time-delay control. By driving the marking machine 10 to move and run precisely in real time according to the detection results during the continuous operation of the amorphous ribbon, the defect location is transformed from data recording into an intuitive and permanent mark on the surface of the amorphous ribbon. This realizes the online marking function synchronized with the continuous production rhythm of the amorphous ribbon, improving the automation level from detection to marking and the overall operation efficiency.

[0044] See Figure 2 and Figure 6 The device also includes two sets of positioning components mounted opposite each other in the main frame 01, through which the amorphous ribbon passes to stably clamp the amorphous ribbon during the marking process and prevent its displacement, thereby ensuring the accuracy of the marking position. The positioning components are located behind the marking components.

[0045] The positioning components include: an electric pusher 13 fixedly installed inside the main frame 01; and a clamping frame 14 fixedly installed at the output end of the electric pusher 13;

[0046] Two sets of electric pushers 13 will drive two sets of clamping frames 14 to approach or separate from each other, thereby clamping and releasing the amorphous ribbon. The surface of the clamping frame 14 that contacts the amorphous ribbon is provided with friction texture 14a to increase friction and enhance clamping stability.

[0047] When the control unit operates the marking machine 10 to perform marking, the positioning components will operate synchronously: the electric pusher 13 drives the upper and lower clamping frames 14 to move towards each other, stably clamping the amorphous ribbon and keeping it stationary during the marking of the marking machine 10; after marking is completed, the clamping frames 14 release the amorphous ribbon and allow it to continue to be transported; the control unit controls this process in conjunction with the marking action to ensure that each marking is completed in the positioning state of the amorphous ribbon.

[0048] This device uses a positioning component to combine electric clamping with frictional resistance to reduce the vibration and displacement of amorphous ribbon during high-speed operation. It solves the problem of mark drift caused by movement during continuous production of amorphous ribbon, thereby improving the accuracy and positional consistency of defect marks and providing a precise positioning reference for subsequent processes.

[0049] See Figure 2 , Figure 7 and Figure 8 The device also includes a buffer assembly installed in the main frame 01, which is used to buffer the displacement segment of the amorphous strip caused by the continuous conveying of the roller when the positioning assembly clamps the amorphous strip, so as to ensure that the production process is continuous and uninterrupted. Its position is located behind the positioning assembly.

[0050] The buffer assembly includes: mounting brackets 15 fixedly installed on both sides inside the main frame 01; two sets of guide shafts 16 rotatably installed between the tops of the two sets of mounting brackets 15; an adjusting bracket 17 slidably installed between the sliding shafts on the mounting brackets 15; an adjusting shaft 18 rotatably installed on the adjusting bracket 17; and a return spring 19 fitted on the sliding shaft of the mounting bracket 15, with its two ends fixed to the mounting bracket 15 and the adjusting bracket 17 respectively.

[0051] The amorphous strip passes sequentially around the front guide shaft 16, the adjusting shaft 18, and the rear guide shaft 16, thus forming a controllable excess strip within the buffer assembly. When the positioning assembly clamps the amorphous strip, the roller conveyor continues to transport it. The amorphous strip at the rear is tensioned due to being fixed, which drives the adjusting frame 17 to move upward along the sliding shaft, compressing the return spring 19 and gradually releasing the excess strip in the buffer assembly to absorb the displacement difference between the front and rear sections. After the positioning is released, the return spring 19 pushes the adjusting frame 17 to reset and re-store the strip.

[0052] This device uses the movable adjustable shaft 18 and reset structure in the buffer assembly to effectively absorb the changes in the length of the amorphous strip during the positioning process without interrupting the operation of the roller mill. This enables dynamic tension management and continuous feeding, thereby avoiding efficiency losses and impact vibration problems caused by frequent start-stop of the roller mill, and thus improving the continuity, stability and overall efficiency of production.

[0053] See Figure 1 , Figure 8 , Figure 9 and Figure 10The device also includes a cleaning component assembled in the main frame 01, which is used to remove impurities attached to the surface of the amorphous ribbon to prevent them from being misjudged as surface defects, thereby ensuring the accuracy of the test results. Its position is located in front of the test component.

[0054] The cleaning components include: a mounting frame 20 fixedly installed within the main frame 01, with a symmetrical structure and an air inlet slot 20a in the middle through which amorphous ribbon material passes; collection chambers 21 inserted into the upper and lower sides of the mounting frame 20 for collecting impurities; both the collection chambers 21 and the mounting frame 20 have interfaces 21a, which are interconnected; the collection chambers 21 have exhaust vents 21b and contain filters for exhausting airflow and trapping impurities; a guide pipe 22 fixedly installed within the mounting frame 20, which connects the air inlet slot 20a to the interface 21a on the mounting frame 20; three sets of combinations of guide pipes 22 and interfaces 21a are provided on the upper and lower sides of the mounting frame 20, and three corresponding interfaces 21a are provided on each collection chamber 21; two sets of mounting pipes 23 fixedly installed on the mounting frame 20, corresponding to the positions of the collection chambers 21 on both sides; and a fan wheel 23 rotating on each mounting pipe 23. 4. Each mounting pipe 23 is equipped with three impellers 24, with each impeller 24 positioned corresponding to the inlet of each air guide pipe 22. The rotation of the impellers 24 generates directional airflow to adsorb impurities on the surface of the amorphous ribbon, allowing them to enter the collection chamber 21 through the air guide pipe 22 and the interface 21a, where they are finally intercepted by the filter screen, and the airflow is discharged from the exhaust port 21b. A drive shaft 25 is rotatably installed in each mounting pipe 23. A bevel gear set 26, consisting of two mutually perpendicular meshing bevel gears, is located between each drive shaft 25 and its corresponding three impellers 24, i.e., there are six sets of bevel gear sets 26, to achieve power transmission. Four sets of cleaning rollers 29 are rotatably installed on the mounting frame 20, symmetrically arranged on both sides of the air inlet slot 20a. A flat gear set 30, consisting of two mutually meshing flat gears, is located between the two cleaning rollers 29 on the same side, i.e., there are two sets of flat gear sets 30, to achieve reverse transmission, aiming to improve the cleaning effect on the surface of the amorphous ribbon.

[0055] The device also includes: a second motor 27 fixedly mounted on the mounting frame 20; and a transmission belt assembly 28 assembled between the output end of the second motor 27, the transmission shaft 25, and the cleaning roller 29 to realize power transmission.

[0056] The second motor 27 is started, which drives the cleaning roller 29 and the drive shaft 25 to rotate synchronously through the transmission belt group 28. On the one hand, the impeller 24 generates suction force to suck the loose impurities on the surface of the amorphous strip into the collection chamber 21. On the other hand, the cleaning rollers 29 rotate in opposite directions to brush away or peel off the more firmly attached impurities, improving the comprehensiveness of cleaning. Finally, the impurities are trapped in the collection chamber 21 by the filter screen and can be taken out for processing after the processing is completed.

[0057] This device combines airflow adsorption with mechanical cleaning in its cleaning assembly to efficiently remove impurities from the surface of amorphous ribbons, effectively avoiding false detections caused by adhering impurities. Its modular collection chamber 21 facilitates unified impurity handling and convenient maintenance. The integrated transmission structure provides driving force from a single motor, resulting in a compact structure and low energy consumption. In summary, the cleaning assembly ensures detection accuracy while enhancing the overall automation and cleaning efficiency of the device.
