Description

Technical Field

[0001] This application relates to the field of amorphous alloy material processing technology, and in particular to a device and method for removing the glass cladding layer of amorphous alloy wire. Background Technology

[0002] Amorphous alloy wires possess excellent giant magnetoresistance (GMR) effects, small size, and high strength, and are commonly used as high-precision magnetic sensitive elements, finding important applications in electrical engineering, aerospace, and defense industries. The fabrication of amorphous alloy wires involves placing an amorphous alloy block into a glass tube, heating it to a molten state, wrapping it around softened glass, and then drawing it into a wire. This alloy amorphous wire is wrapped with a glass skin. During use, when soldering the amorphous alloy wire to other circuit components, the presence of the glass layer makes soldering difficult. Furthermore, the tight wrapping of the alloy amorphous wire by the glass layer creates unreleased stress, leading to poor consistency in the GMR effect and reduced magnetic sensitivity. Therefore, removing the glass coating is essential.

[0003] Currently, methods for removing glass coating include chemical etching. Patent publication number CN102976634A, titled "Alloy Microwire Glass Coating Removal Device," mentions using a specific etching solution to etch and remove the glass layer, followed by cleaning with a cleaning solution and ultrasonic cleaning. This method requires the use of highly corrosive solvents that can corrode glass, such as hydrofluoric acid. The degree of corrosion is difficult to control during the operation, and it is easy to corrode the alloy wire. Moreover, the reagents are highly corrosive and toxic, making the operation process relatively dangerous and increasing the difficulty of mass production.

[0004] Another method for removing glass coating is mechanical grinding. Patent publication number CN117655887A, titled "A Glass-Coated Metal Wire Removal Equipment and Method," mentions using a grinding wheel to grind and remove the surface of the glass-coated metal wire. This method is prone to damaging the metal, and it is also very difficult to accurately control the grinding wheel to prevent breakage. Summary of the Invention

[0005] The purpose of this application is to provide a device and method for removing the glass cladding layer of amorphous alloy wire, so as to solve the problems of high chemical corrosion hazards, easy damage to the wire body by mechanical polishing, and difficulty in process control in the prior art.

[0006] To achieve the above objectives, this application provides the following solution: In a first aspect, this application provides an apparatus for removing the glass cladding layer of an amorphous alloy wire, comprising: The substrate unwinding assembly and substrate winding assembly are located at the beginning and end of the amorphous alloy wire glass cladding layer removal device, respectively, and are used for unwinding and winding the amorphous alloy wire. A tension control component is connected in series in the transmission path between the substrate unwinding component and the ultrasonic crushing component, and is used to monitor the tension value of the amorphous alloy wire during transmission in real time. The ultrasonic fragmentation assembly includes a contour-following clamping vibration guide device, a main ultrasonic transducer, an auxiliary ultrasonic transducer, and an ultrasonic driver. The contour-following clamping vibration guide device, located after the tension sensor, consists of upper and lower vibration guide blocks that clamp the wire channel. The main ultrasonic transducer and the auxiliary ultrasonic transducer are installed inside the vibration guide blocks to generate ultrasonic vibration signals. The ultrasonic driver drives the main ultrasonic transducer and the auxiliary ultrasonic transducer. The negative pressure collection assembly includes a negative pressure suction hood, a vacuum pump, and a first filter connected in sequence; the negative pressure suction hood is wrapped around the outside of the contour clamping vibration guide device and is used to collect glass shards generated after the amorphous alloy wire glass cladding layer breaks using negative pressure. The multi-stage cleaning assembly includes an integrated cleaning tank, a circulation pump, and a second filter; the integrated cleaning tank is located after the ultrasonic disruption assembly and has multiple partitions inside for removing residues through multi-stage ultrasonic water bath cleaning. An online inspection component, located between the cleaning tank outlet and the substrate winding component, is used to acquire surface images, identify residual glass, and determine quality. The system control unit is electrically connected to the take-up motor, unwind motor, ultrasonic driver, tension sensor, vacuum pump, circulation pump, and online detection components, and is used to coordinate and control all actions and execute closed-loop logic algorithms.

[0007] Secondly, this application provides a method for removing the glass cladding layer of an amorphous alloy wire, comprising: An unwinding motor is used to unwind and pull the amorphous alloy wire. At the same time, a tension sensor is used to measure the tension of the wire in real time during the transmission process. The running torque of the unwinding motor is adjusted according to the tension to keep the amorphous alloy wire in a constant straight state, so as to obtain a stable conveying wire to be processed. The stable conveyed filament to be processed is fed into the conformal clamping vibration guide device. Through the micro-arc groove tunnel formed by the cooperation of the upper and lower vibration guide blocks, the working surface of the vibration guide block evenly wraps the glass layer on the surface of the circular filament to be processed, forming a stable coupling interface between the filament and the main ultrasonic transducer and the auxiliary ultrasonic transducer, and determining the initial contact state. Based on the initial contact state, the main ultrasonic transducer and the auxiliary ultrasonic transducer are activated to work together to determine the intermediate products of glass embrittlement. Specifically, this includes: operating the main ultrasonic transducer on the contour clamping vibration guide device at a set resonant frequency to excite resonance inside the glass layer, and operating the auxiliary ultrasonic transducer at another set frequency to generate shear force. The phase difference between the two ultrasonic bands is adjusted by the system control unit to form a stress focusing band within the glass layer. Based on the stress focusing band, pulse output is performed using time-series collaborative control technology to achieve internal stress accumulation and fragmentation of the glass coating layer, thereby determining the intermediate products of glass embrittlement. Based on the glass embrittlement intermediate product, the negative pressure suction hood located around the contour clamping vibration guide device is activated. At the moment when the glass layer cracks along the axial direction, the shattered glass shards are sucked into the first filter by the negative pressure airflow in the slit, and the processed amorphous alloy is obtained. The treated amorphous alloy wire is introduced into a multi-stage cleaning assembly and passes through a multi-layer ultrasonic cleaning tank formed by partitions in sequence to achieve step-by-step cleaning. The cleaning solution carries residual fine debris under the action of a circulating pump. After passing through the second filter to intercept glass debris, it flows back to the inlet of the multi-layer ultrasonic cleaning tank to obtain clean wire. The multi-layer ultrasonic cleaning tank is an integrated cleaning tank. Online image recognition is performed using an optical microscope camera to analyze the distribution of residual glass on the surface of clean filaments. The detection results are fed back to the system control unit in real time, and products with abnormal detection results are sorted for quality control.

[0008] According to the specific embodiments provided in this application, this application has the following technical effects: This application provides a device and method for removing the glass cladding layer from amorphous alloy wire. The amorphous alloy wire is unwound and wound into finished product using a substrate unwinding assembly and a substrate winding assembly. A tension control assembly monitors the tension value of the amorphous alloy wire during transmission in real time to prevent breakage. An ultrasonic crushing assembly clamps the amorphous alloy wire and generates ultrasonic vibration signals to vibrate it. A negative pressure collection assembly collects the glass slag generated from the broken amorphous alloy wire. A multi-stage cleaning assembly then cleans the amorphous alloy wire. Finally, an online detection assembly identifies whether there is glass residue in the cleaned amorphous alloy wire and performs a quality assessment. The entire process is controlled by a system control unit, achieving automatic removal of the glass cladding layer from the amorphous alloy wire. The entire process requires no chemical reagents to corrode the glass or mechanical polishing. The ultrasonic vibration signals used to vibrate the amorphous alloy wire do not damage the wire itself, reducing the difficulty of process control. Attached Figure Description

Detailed Implementation

[0011] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] To make the objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] The specific configuration and connection relationship of each component in the amorphous alloy wire glass cladding layer removal device provided in this application embodiment are shown in Table 1.

[0014] Table 1

[0015] like Figure 1 As shown in the figure, this application provides an amorphous alloy wire glass cladding layer removal device, comprising: The substrate unwinding assembly and substrate winding assembly are located at the beginning and end of the amorphous alloy wire glass cladding layer removal device, respectively, and are used for unwinding and winding the amorphous alloy wire.

[0016] A tension control component is connected in series on the transmission path between the substrate unwinding component and the ultrasonic crushing component, and is used to monitor the tension value of the amorphous alloy wire during transmission in real time.

[0017] The ultrasonic breaking assembly includes a contour-following clamping vibration guide device 40, a main ultrasonic transducer 31, an auxiliary ultrasonic transducer 32, and an ultrasonic driver. The contour-following clamping vibration guide device 40 is located after the tension sensor 20 and consists of two upper and lower vibration guide blocks that clamp the wire channel. The main ultrasonic transducer 31 and the auxiliary ultrasonic transducer 32 are installed inside the vibration guide blocks to generate ultrasonic vibration signals. The ultrasonic driver is used to drive the main ultrasonic transducer 31 and the auxiliary ultrasonic transducer 32.

[0018] The negative pressure collection assembly includes a negative pressure suction hood 50, a vacuum pump 51, and a first filter 52 connected in sequence; the negative pressure suction hood 50 is wrapped around the outside of the contour clamping vibration guide device 40 and is used to collect glass shards generated after the amorphous alloy wire glass cladding layer is broken by using negative pressure.

[0019] The multi-stage cleaning assembly includes an integrated cleaning tank 60, a circulation pump 61, and a second filter 62; the integrated cleaning tank 60 is located after the ultrasonic breaking assembly and has multiple partitions inside for removing residues through multi-stage ultrasonic water bath cleaning.

[0020] An online inspection component, located between the cleaning tank outlet and the substrate winding component, is used to acquire surface images, identify residual glass, and determine quality.

[0021] The system control unit 80 is electrically connected to the take-up motor 11, the unwind motor 10, the ultrasonic driver, the tension sensor 20, the vacuum pump 51, the circulation pump 61, and the online detection component, respectively, and is used to coordinate and control all actions and execute a closed-loop logic algorithm. This closed-loop logic algorithm works as follows: after the filament is ultrasonically crushed and cleaned, the online detection component detects the residual glass. Based on the glass residue level, the ultrasonic driver adjusts the ultrasonic parameters (for example, if the detected glass fragments exceed the acceptable limit, the duration of the main and auxiliary ultrasonic waves is increased), thus forming a closed-loop control.

[0022] The closed-loop logic algorithm of the system control unit 80 is as follows: Figure 2 As shown.

[0023] The working principle of this application is as follows: Conveying stage: The system control unit 80 drives the unwinding motor 10 to operate, unfolding the alloy wire. The wire passes through the tension sensor 20. If tension fluctuation is detected, the controller automatically fine-tunes the torque of the winding motor 11 to ensure that the wire enters the next process at a constant speed and constant tension level.

[0024] Coupling and Breakage: The filament is inserted into the contour-following clamping vibration guide device 40, which consists of two guide blocks that clamp together to form a cylindrical tunnel. Due to the design of the micro-arc groove 41, the guide blocks tightly and uniformly wrap around the filament. The system control unit 80 controls the ultrasonic driver to drive the dual transducers (i.e., the main ultrasonic transducer 31 and the auxiliary ultrasonic transducer 32) to generate two ultrasonic signals, which form a specific interference field on the working surface of the guide head through phase modulation. This multi-frequency synergy causes the glass layer to resonate and break, and the micro-textured structure 42 guides the crack to extend axially.

[0025] Collection and separation: While the ultrasonic crushing is in progress, the vacuum pump 51 is activated, and the slit in the negative pressure suction hood 50 generates a high-speed airflow, which directly sucks the detached glass fragments away from the work point and collects them through the filter to prevent them from falling back onto the wire surface.

[0026] Deep cleaning: The pre-cleaned wire enters the integrated cleaning tank 60. The cleaning tank is divided into multiple ultrasonic cleaning layers by partitions. Water flows from one side through a circulation pump 61, forming an upward flow field. Combined with the ultrasonic cavitation effect, this thoroughly removes the glass shards adhering to the alloy wire. The glass shards intercepted by the filter screen are cleaned regularly to keep the tank solution clean.

[0027] Intelligent quality inspection: After cleaning, the filament passes under the visual inspection unit 70, where an optical microscope captures the image. An AI algorithm analyzes the grayscale values ​​and texture features in the image to determine if any glass residue remains. If residue is found, the data is fed back to the system control unit 80, which adjusts the front-end ultrasonic power or extends the action time (for subsequent batches or real-time fine-tuning). Qualified products are wound up normally, while unqualified products are alarmed and rejected.

[0028] In one exemplary embodiment, such as Figure 3 As shown in (a)-(c), the working surface of the guide block of the contour clamping vibration guide device 40 that contacts the amorphous alloy wire has a micro-arc groove 41.

[0029] The radius of curvature of the micro-arc groove 41 matches the diameter of the amorphous alloy wire.

[0030] The inner wall of the micro-arc groove 41 is etched with a micro-texture structure, and the texture direction is consistent with the axis of the amorphous alloy wire, which is used to form directional stress concentration and guide the glass layer to crack along the axis.

[0031] In an exemplary embodiment, the main ultrasonic transducer 31 and the auxiliary ultrasonic transducer 32 are mounted side-by-side or integrated inside the upper guide block; the ultrasonic driver includes a first driver 34 and a second driver 35, the first driver 34 is connected to the main ultrasonic transducer 31 and the auxiliary ultrasonic transducer 32, and the second driver 35 is connected to the cleaning ultrasonic transducer 33.

[0032] In an exemplary embodiment, the frequency at which the auxiliary ultrasonic transducer 32 operates is a harmonic or low frequency of the resonant frequency of the main ultrasonic transducer 31; the phase difference between the two frequency bands of ultrasonic waves is continuously adjustable from 0° to 360°.

[0033] In an exemplary embodiment, the negative pressure suction hood 50 is wrapped around the outside of the contour clamping vibration guide device 40, and the side wall is provided with a slit communicating with the first filter 52; the negative pressure suction hood 50 maintains a negative pressure value inside, and the glass fragments are adsorbed onto the first filter 52 by airflow.

[0034] In an exemplary embodiment, the integrated cleaning tank 60 is provided with multiple partitions to divide the integrated cleaning tank 60 into multiple ultrasonic cleaning layers; water flows from one side through the circulation pump 61 to form an upward flow field, which, together with the ultrasonic cavitation effect, removes the glass slag adhering to the treated amorphous alloy wire.

[0035] In one exemplary embodiment, the online detection component is a visual detection unit 70, which includes an optical microscope camera.

[0036] The system control unit 80 is used to adaptively adjust the ultrasonic intensity or extend the action time of the ultrasonic fragmentation component based on the image recognition results of the visual detection unit 70.

[0037] like Figure 4 As shown, this application provides a method for removing the glass cladding layer of amorphous alloy wire, comprising: S1: The unwinding motor 10 unfolds and pulls the amorphous alloy wire, while the tension sensor 20 measures the tension of the wire in real time during the transmission process. The running torque of the unwinding motor 10 is adjusted according to the tension to keep the amorphous alloy wire in a constant straight state, so as to obtain a stable conveying wire to be processed.

[0038] S2: The stable conveyed filament to be processed is fed into the contour clamping vibration guide device 40. Through the tunnel formed by the micro-arc groove 41 formed by the cooperation of the upper and lower vibration guide blocks, the working surface of the vibration guide block evenly wraps the glass layer on the surface of the circular filament to be processed, forming a stable coupling interface between the filament and the main ultrasonic transducer and the auxiliary ultrasonic transducer, and determining the initial contact state.

[0039] S3: Based on the initial contact state, the main ultrasonic transducer and the auxiliary ultrasonic transducer are activated to work together to determine the intermediate products of glass embrittlement. Specifically, this includes: the main ultrasonic transducer 31 on the conformal clamping vibration guide device 40 is set to operate at a set resonant frequency to excite resonance within the glass layer, and the auxiliary ultrasonic transducer 32 is set to operate at another set frequency to generate shear force. The phase difference between the two ultrasonic bands is adjusted by the system control unit 80 to form a stress focusing band within the glass layer. Based on the stress focusing band, pulse output is performed using timing-coordinated control technology to achieve internal stress accumulation and fragmentation of the glass cladding layer, thus determining the intermediate products of glass embrittlement. The two ultrasonic waves undergo constructive / destructive interference to form a "stress focusing band" in the glass layer, and the resulting ultrasonic fragmentation process is as follows: Figure 5 As shown.

[0040] S4: Based on the glass embrittlement intermediate product, the negative pressure suction hood 50 located around the contour clamping vibration guide device 40 is activated. At the moment when the glass layer cracks along the axial direction, the broken glass shards are sucked into the first filter 52 by the negative pressure airflow in the slit to obtain the processed amorphous alloy.

[0041] S5: The treated amorphous alloy wire is introduced into the multi-stage cleaning assembly and passes through the multi-layer ultrasonic cleaning tank formed by the partitions in sequence to achieve step-by-step cleaning. The cleaning liquid carries the residual fine debris under the action of the circulating pump 61. After passing through the second filter 62 to intercept glass fragments, it flows back to the inlet of the multi-layer ultrasonic cleaning tank to obtain clean wire. The multi-layer ultrasonic cleaning tank is an integrated cleaning tank 60.

[0042] S6: Online image recognition is performed using an optical microscope camera to analyze the distribution of residual glass on the surface of the clean filament, and the detection results are fed back to the system control unit 80 in real time. Products with abnormal detection results are then sorted for quality control.

[0043] In practical applications, S1 is the feed and tension control step.

[0044] The unwinding motor 10 unfolds and pulls the alloy wire, while a tension sensor measures the tension of the wire in real time during transmission and feeds the measurement signal back to the system control unit 80. The operating torque of the two drive motors is adjusted according to the tension to keep the alloy wire in a constant taut state so that it can smoothly enter the subsequent processing station, thus obtaining a stable conveyed wire to be processed.

[0045] S2 is the contour clamping contact step.

[0046] The stable conveying filament obtained in S1 is fed into the contour clamping vibration guide device; through the micro-arc groove tunnel formed by the cooperation of the upper and lower vibration guide blocks, the working surface of the vibration guide block uniformly wraps the glass layer on the surface of the circular filament instead of point or line contact; a stable coupling interface is formed between the filament and the main ultrasonic transducer and the auxiliary ultrasonic transducer; and an initial contact state with maximized energy transfer efficiency and no local stress concentration is obtained.

[0047] S3 is the multi-band phase modulation breaking step.

[0048] Based on the initial contact state in S2, the dual transducers work together: the main ultrasonic transducer on the contour clamping vibration guide device operates at a specific resonant frequency Fr, exciting resonance inside the glass layer; the auxiliary ultrasonic transducer operates at another specific frequency (such as harmonics or low frequencies of Fr), generating shear force; and the phase difference between the two ultrasonic bands is adjusted by the system control unit (0°-360° continuously adjustable), forming a "stress focusing zone" within the glass layer; pulse output is achieved using time-series collaborative control technology (low-frequency preprocessing → phase modulation breakage → high-frequency fine finishing); the maximum stress accumulation and fragmentation inside the glass cladding layer are realized, while the ineffective vibration energy transmitted to the alloy matrix is ​​minimized; an intermediate product in which the glass layer has become brittle but has not peeled off over a large area is obtained.

[0049] S4 is the negative pressure instantaneous absorption and collection step.

[0050] Based on the glass embrittlement intermediate product in S3, the negative pressure suction hood located around the vibration guide device is activated; at the instant the glass layer cracks axially, the negative pressure airflow in the slit is used to suck most of the broken and peeled glass shards into the first filter; to prevent the shards from splashing or re-adhering to the surface of the wire; and to obtain an alloy wire with most of the glass shards initially removed.

[0051] S5 is a multi-stage circulating cleaning step.

[0052] The S4-treated alloy wire is introduced into an integrated cleaning tank; the wire passes through a multi-layer ultrasonic cleaning tank formed by partitions in sequence, realizing step-by-step cleaning of the alloy wire to ensure the final cleanliness and obtain a clean wire with very little surface residue; the cleaning solution carries residual fine debris under the action of a circulating pump, flows through a filter to intercept glass fragments and then flows back to the inlet of the cleaning tank.

[0053] S6 represents the visual inspection and closed-loop feedback steps.

[0054] Based on the clean filament in S5, image recognition is performed using an online optical microscope camera to analyze the distribution of residual glass on the filament surface; the detection results are fed back to the system control unit 80 in real time (such as adjusting the ultrasonic intensity or action time), and products with abnormal detection results are sorted for quality; an adaptive learning closed loop is formed; and the entire glass coating removal process is completed.

[0055] In one exemplary embodiment, the timing-coordinated control technology includes three stages: low-frequency preprocessing, phase modulation breaking, and high-frequency fine-tuning.

[0056] In an exemplary embodiment, the step of feeding back the detection results to the system control unit 80 in real time specifically includes: If residual glass is detected, adjust the ultrasonic intensity of the ultrasonic breaking component or extend the action time.

[0057] If no residual glass is detected, determine whether the cleaned amorphous alloy wire is a qualified product. If so, rewind the cleaned amorphous alloy wire normally. If not, reject the unqualified product and issue an alarm.

[0058] To more clearly illustrate the technical effects of the present invention, a specific implementation will be carried out using the processing of Φ0.1mm Fe-based amorphous wire as an example: Equipment parameter settings: Material: The contour-guided vibration device is made of engineering ceramics doped with boron nitride.

[0059] Ultrasonic parameters: The frequency of the main transducer (31) is set to Fr=125kHz to excite the glass layer resonance; the frequency of the auxiliary transducer (32) is set to 40kHz to generate shear force to assist in peeling. The phase difference is controlled in the range of 90°-180° to obtain the best shearing effect.

[0060] Process sequence: First section (3s-5s) low-frequency preheating; Second section (8s-12s) phase modulation high-amplitude breaking; Third section (2s-3s) high-frequency fine finishing.

[0061] Fluid parameters: The cleaning water flow rate is controlled at 0.2m / s to ensure that it can remove debris without causing the wire to shake.

[0062] Negative pressure value: The internal pressure of the negative pressure suction hood 50 is maintained at -10kPa to -15kPa.

[0063] Process Flow Execution: The system starts up, and the reading of tension sensor 20 stabilizes at 0.5N ± 0.05N.

[0064] The wire enters the vibration guide device, and the ultrasonic testing is activated. At this point, the distinctive crackling sound of breaking glass can be heard, indicating the formation of a crack.

[0065] Vacuum pump 51 starts to draw in the debris, which is then quickly sucked through the first filter 52.

[0066] The filament enters the integrated cleaning tank 60 and undergoes three layers of ultrasonic cleaning before entering the field of view. The vision system identifies and displays the filament, and after multiple iterations and optimizations, the single-scan pass rate reaches over 99%. Figures 6-7 As shown.

[0067] Compared to traditional chemical etching methods, this process produces no acid or alkali emissions; compared to mechanical polishing, the wire surface is free of scratches, the tensile strength does not decrease, the change in giant magnetoresistance ratio is as expected, and the magnetic sensitivity is restored to the level of bare wire.

[0068] This application successfully solves the problems of difficult removal of glass cladding layers from amorphous alloy wires, easy wire damage, and environmental unfriendliness, and realizes continuous and intelligent production.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.

The treated amorphous alloy wire is introduced into a multi-stage cleaning assembly and passes through a multi-layer ultrasonic cleaning tank formed by partitions in sequence to achieve step-by-step cleaning. The cleaning solution carries residual fine debris under the action of a circulating pump. After passing through the second filter to intercept glass debris, it flows back to the inlet of the multi-layer ultrasonic cleaning tank to obtain clean wire. The multi-layer ultrasonic cleaning tank is an integrated cleaning tank. Online image recognition is performed using an optical microscope camera to analyze the distribution of residual glass on the surface of clean filaments. The detection results are fed back to the system control unit in real time, and products with abnormal detection results are sorted for quality control.

9. The method for removing the glass cladding layer of an amorphous alloy wire according to claim 8, characterized in that, The timing-coordinated control technology includes three stages: low-frequency preprocessing, phase modulation breaking, and high-frequency fine-tuning.

10. The method for removing the glass cladding layer of an amorphous alloy wire according to claim 8, characterized in that, The step of feeding back the detection results to the system control unit in real time specifically includes: If residual glass is detected, adjust the ultrasonic intensity of the ultrasonic breaking component or extend the action time; If no residual glass is detected, determine whether the cleaned amorphous alloy wire is a qualified product. If so, rewind the cleaned amorphous alloy wire normally. If not, reject the unqualified product and issue an alarm.
