Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal microfiber manufacturing, and in particular relates to a vibration processing method and device for preparing metal microfibers, an electronic device and a medium. BACKGROUND

[0002] With the development of micro-electro-mechanical system (MEMS) processing technology, miniaturization of various devices and instruments has become the top priority of scientific and technological research and enterprise application, and is closely related to people's life.

DETAILED DESCRIPTION

[0032] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0033] The vibration processing method, device, electronic equipment and storage medium for preparing metal microfibers of the embodiments of the present application are described below with reference to the drawings. In view of the problem that the related technologies mentioned in the above background technology cannot manufacture metal microfibers with high size and shape requirements, the present application provides a vibration processing method for preparing metal microfibers, in which, by designing a large-amplitude vibration device according to different microfiber structure requirements, a specific vibration trajectory is applied to the tool by the device, and the processing parameters are adjusted to realize the microfiber structure processing of the target metal, thereby solving the problem that the related technologies cannot manufacture metal microfibers with high size and shape requirements, and metal microfibers with high size and shape requirements can be efficiently and in large quantities.

[0034] Specifically, Figure 1 A flowchart of a vibration processing method for preparing metal microfibers provided by the embodiments of the present application is shown.

[0035] As Figure 1 shown, the vibration processing method for preparing metal microfibers includes the following steps:

[0036] In step S101, the current microfiber structure requirement of the target metal is obtained.

[0037] Specifically, obtaining the current microfiber structure requirement of the target metal includes but is not limited to obtaining the target metal attribute, the parameter of the current microfiber structure, and the current microfiber requirement, wherein the attribute of the target metal material includes the brittle plasticity of the metal material, etc., the parameter of the microfiber structure includes the length, the width, the thickness, the shape, etc. The microfiber can be considered according to the actual application, the transportation condition, etc. It can be separated from the surface or not.

[0038] In step S102, the target vibration device, the target tool, the processing parameter, and the vibration trajectory and vibration parameter of the target tool are determined according to the current microfiber structure requirement.

[0039] Optionally, in some embodiments, the processing parameter includes at least one of the cutting speed, the cutting depth, and the cutting width.

[0040] Optionally, in some embodiments, the vibration trajectory is an elliptical trajectory.

[0041] Optionally, in some embodiments, the vibration tool trajectory parameter includes at least one of the vibration frequency, the vibration amplitude, the vibration direction, and the vibration phase.

[0042] Wherein, the target tool can be but not limited to a diamond tool, and the parameters of the tool can include a rake angle, a relief angle and a rake face shape.

[0043] Specifically, the target tool parameters and shapes can be as shown in Figure 2 The tool head material used can be diamond but is not limited to this material, and the tool base material can be a tool steel material. The tool head is permanently bonded to the tool base material. The rake angle of the tool is 0°. Other parameters include a tool arc radius r and a tool relief angle θ. The tool arc radius and the relief angle are closely related to the size of the metal microfiber being processed.

[0044] The structure of the target vibration device can be as shown in Figure 3 The tool is placed at the head of the amplification device. The amplification device couples the vibration of the piezoelectric stack to the device head through a flexible bridge structure, causing the tool to form a complex trajectory. The piezoelectric stack is fixed in the amplification device by a fixed tail cap and a ball head bolt, ensuring centring and stable vibration. The amplification device is fixed to the base plate by a fixing bolt. By adjusting the flexible bridge structure of the amplification device, the maximum amplitude of the amplification device can exceed 30 microns, and the resonant frequency is greater than 70,000 Hz, meeting the processing requirements of high aspect ratio metal microfibers.

[0045] In step S103, based on the processing parameters and vibration parameters, a vibration trajectory is applied to the target tool using the target vibration device to vibration process the microfiber structure of the target metal.

[0046] Specifically, after determining the processing parameters and vibration parameters, the tool is made to vibrate at a frequency f based on the processing parameters and vibration parameters. The vibration motion trajectory can be as shown in Figure 4 The tool vibration can be any trajectory, including but not limited to Figure 4 The tool can also be synthesized by the vibration device. The tool cutting depth is b, and the feed speed is Vc. Then the period length h is:

[0047]

[0048] The tool performs vibration cutting on the metal substrate, cutting a layer of metal material with a thickness of b into metal microfibers with uniform size and shape piece by piece. By adjusting the parameters, the metal microfibers can be left on the substrate surface or completely separated from the substrate. As shown in Figure 4 The tool moves along the tool relief angle θ to uniformly separate the unformed microfibers from the substrate within one period, and then completely separates them through the transverse feed at the lowermost end. When the transverse motion length is less than the period length, the metal microfibers will be left on the substrate surface.

[0049] The size and shape of the processed metal microfibers are as shown in Figure 5As shown, the size of the metal microfiber includes a microfiber length l, a microfiber width b, and a microfiber thickness h. The shape of the microfiber is determined by the tool shape, the vibration trajectory, the feed speed, and the cutting depth, including but not limited to Figure 4 As shown, the shape. The microfiber thickness is the period length of the processing, the microfiber width is the cutting depth, and the microfiber length is determined by the cutting depth and the tool arc radius:

[0050]

[0051] By matching the tool, the vibration trajectory, and the processing parameters, the microfiber structure meeting the requirements can be obtained. In addition, in combination with the metal material properties and the processing parameters, different microfiber structures can be processed in the same metal material.

[0052] The embodiment of the present application can also process the pure copper surface into metal microfibers in a high-efficiency and large quantity by increasing the vibration frequency. Tens of thousands of metal microfibers with uniform size and shape and high aspect ratio can be processed in one second. The processing results of the embodiment of the present application are shown in Figure 6 and Figure 7 As shown, in (a) of FIG. 8, the magnification is 100 μm, Figure 7 (b) of FIG. 8 is a 50 μm magnification, Figure 7 (c) of FIG. 8 is a 5 μm magnification, and the metal matrix and the uniform metal microfibers thereon can be clearly seen. The embodiment of the present application can process the high aspect ratio metal microfibers for MEMS stress and strain sensors, micro injectors, micro spectrometers, and other devices. Figure 7 Optionally, in some embodiments, after the vibration trajectory is applied to the target tool by the target vibration device to vibrate and process the microfiber structure of the target metal, the method further includes: identifying whether the microfiber structure of the target metal meets the current microfiber structure requirement; if the microfiber structure of the target metal does not meet the current microfiber structure requirement, adjusting the processing parameters and / or the vibration parameters to obtain new processing parameters and / or new vibration parameters; and reapplying the vibration trajectory to the target tool by the target vibration device to vibrate and process the microfiber structure of the target metal based on the new processing parameters and / or the new vibration parameters.
