The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and are not to be construed as limiting the present application.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "multiple" means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] like Figure 1As shown, an embodiment of the present application provides a circular arc groove microstructure processing device, which includes a rotating unit 101 and a processing line 102. The rotation of the rotating unit 101 drives the processing line 102 to rotate. The processing line 102 has a cutting capability. When a workpiece contacts the processing line 102, the processing line 102 performs cutting. Due to the shape of the processing line 102, the cutting process automatically forms a groove. To ensure that the machined groove meets the groove shape requirements of the workpiece, the workpiece also performs adaptive movement during the cutting process, cooperating with the movement of the rotating unit 101 to complete the processing of the groove microstructure.

[0041] like Figure 2 As shown, the rotating unit 101 can rotate, and the processing line 102 is set on the rotating unit 101. In order to arrange the processing line 102 as required, a corresponding positioning structure is set on the rotating unit 101.

[0042] like Figure 3 、 Figure 4 、 Figure 5 As shown, in some examples, the processing line 102, serving as the primary carrier for contacting and cutting the workpiece, surrounds the sidewall of the rotating unit 101. The groove profile of the workpiece to be processed is required to be relatively regular, meaning that the distance between each groove is approximately equal. To facilitate efficient processing of multiple parallel grooves at once and to facilitate the configuration of the processing line 102, the processing line 102 spirals around the rotating unit 101 multiple times. It will be appreciated that, based on the groove profile requirements, the spiral shape formed by the processing line 102 has a relatively fixed pitch, avoiding the need for multiple parallel processing lines 102, thereby reducing the difficulty of securing the processing line 102 and improving the groove quality.

[0043] Furthermore, abrasives 103 are attached to the processing line 102 , and the abrasives 103 are approximately evenly distributed at various positions of the processing line 102 , ensuring that various parts of the groove can be cut approximately equally during the cutting process.

[0044] When machining the arc groove microstructure on the workpiece, the cross-sectional shape of the machining line 102 is set to be approximately circular. When the circular machining line 102 cuts the workpiece, it naturally forms an arc-shaped groove, reducing the subsequent tedious grinding process and indirectly improving machining efficiency. The rotation of the rotating unit 101 drives the machining line 102 to rotate together. At this time, when the workpiece surface contacts the machining line 102, a groove can be cut. To ensure the effectiveness of the cutting process of the machining line 102, the machining line 102 protrudes from the side wall of the rotating unit 101 to prevent the rotating unit 101 from contacting the workpiece surface and causing damage to the workpiece surface.

[0045] Specifically, the processing wire 102 is manufactured by mechanical action, brazing, resin bonding, or electroplating. The processing wire 102 and the granular abrasive 103 are bonded together by a bonding agent. The processing wire 102 can be made of high-strength steel wire, and the bonding agent can be a brazing material such as a Ni-B-Cr matrix alloy, Cu-Sn-Ti, Cu-Ag-Ti, or Ni-Cr-B-Si, a thermosetting resin bond, a light-curing resin bond, or an electroplated nickel alloy. The abrasive 103 can be made of diamond, cubic boron nitride, corundum, or silicon carbide. The outer diameter of the processing wire 102 containing the abrasive 103 layer is set to 0.3 to 2 mm.

[0046] The average particle size of the abrasive 103 ranges from 5 to 500 microns. The abrasive 103 is bonded by a binder, and there is a high bonding strength between the binder and the abrasive 103. During the processing, the binder is worn away, exposing the abrasive 103. The abrasive 103 particles on the processing line 102 form a continuous and effective cutting process on the workpiece surface, and can form controllable arc surface grooves on the workpiece surface.

[0047] like Figure 3 As shown, in some examples, in order to ensure the spiral winding form of the processing line 102 and to ensure the connection strength between the processing line 102 and the rotating unit 101, a positioning portion 104 is provided on the rotating unit 101. The processing line 102 is connected to the positioning portion 104. It can be understood that the positioning portion 104 is spirally wound around the side wall of the rotating unit 101 and ensures a relatively fixed pitch. At the same time, the positioning portion 104 protrudes from the side wall of the rotating unit 101, and the processing line 102 is connected to and protrudes from the outer edge of the positioning portion 104. While stabilizing the position of the processing line 102, it further protrudes from the rotating unit 101 to prevent the rotating unit 101 from touching the workpiece with a large contact area when the workpiece is fed too much, causing irreparable serious damage to the workpiece.

[0048] like Figure 5 As shown in the partial enlarged Figure I, in order to ensure that the processing line 102 is stably located on the outer edge of the positioning portion 104, a connecting groove 105 is provided on the outer edge of the positioning portion 104. The depth of the connecting groove 105 is less than the outer diameter of the processing line 102, so that the processing line 102 can protrude from the positioning portion 104 while being embedded in the connecting groove 105, thereby forming effective cutting of the processing line 102.

[0049] In some examples, in order to facilitate the fixing of the position of the processing line 102, the processing line 102 is extended and connected to both ends of the rotating unit 101, wherein the processing line 102 and the rotating unit 101 are detachably connected, so that the processing line 102 can be replaced in the case of severe wear, thereby improving the durability of the arc groove microstructure processing device.

[0050] In some examples, since it is difficult to ensure that the processing line 102 extends accurately in the form of a spiral line to both ends of the rotating unit 101 for fixation, a mounting portion 106 is provided on the side wall of the rotating unit 101, and the mounting portion 106 is located at both ends of the rotating unit 101.

[0051] Furthermore, mounting portion 106 is provided with mounting grooves 107, which extend to the connection positions at both ends of rotation unit 101. After forming a spiral line, processing line 102 is embedded in mounting grooves 107, thereby extending to both ends of rotation unit 101. It can be understood that mounting grooves 107 are connected to connection grooves 105, facilitating the continuous embedding of processing line 102.

[0052] Specifically, connection holes are provided at both ends of the rotating unit 101 , namely at the end positions of the mounting groove 107 , and fasteners can be installed in the connection holes to squeeze and fix the processing line 102 .

[0053] In some examples, the positioning portion 104, connecting groove 105, connecting hole, and other structures can be prepared by turning, milling, grinding, drilling, etc. The rotating unit 101 is made of 45 steel. The base size parameters of the rotating unit 101 are as follows: the outer diameter is set to 50 to 500 mm, the length is set to 100 to 1000 mm, the area where the positioning portion 104 is located is the working area, and the length of the working area is set to 80 to 800 mm. The depth of the positioning portion 104 is set to 0.1 to 5 mm, the width between two adjacent circles of positioning portions 104 is set to 0.1 to 5 mm, the depth of the connecting groove 105 is set to 0.2 to 2 mm, the width of the connecting groove 105 is set to 0.2 to 2 mm, the width of the edge of the connecting groove 105 is set to 0.1 to 0.5 mm, the pitch is set to 0.2 to 5 mm, and the thread lead angle is set to 2° to 30°.

[0054] Specifically, the processing line 102 and the connection groove 105 are fixed by an adhesive. When the processing line 102 is worn, the adhesive can be removed by heating or dissolving the adhesive to replace the processing line 102.

[0055] In some examples, during the installation of the processing line 102, the rotating unit 101 is first cleaned to remove grease and dust from the surface, and then placed in a drying oven for drying. After drying, the processing line 102 is fixed to one end of the rotating unit 101 by fasteners such as bolts and gaskets. The processing line 102 is then wound along the trajectory of the connecting groove 105 and the installation groove 107. The pre-adjusted adhesive is added simultaneously during the winding process. After the winding is completed, the other end of the processing line 102 is also fixed by fasteners. Finally, it is placed at room temperature for 6 to 72 hours to achieve complete curing. The efficiency of the drying process can be improved by heating. Usually, heating and curing are performed in a hot oven at 50°C to 120°C.

[0056] The rotating unit 101 moves in coordination with the workpiece and utilizes material removal to first machine a continuous arc microgroove array of different sizes on the workpiece surface. The work platform 201 rotates a certain angle and then performs a second machining to obtain an arc microgroove array that intersects with the arc microgroove array machined for the first time. The unmachined areas between the arc grooves form microcolumn or microcone arrays of different sizes and shapes, whose sizes and shapes are determined by the tool size and the worktable rotation angle.

[0057] Specifically, if Figure 7 As shown, in the first embodiment, between two cutting processes, the working platform 201 rotates 90° to form a 90° processing angle microstructure array; Figure 8 As shown, in the second embodiment, between two cutting processes, the working platform 201 rotates at an angle other than 90°, forming a microstructure array with a non-90° processing angle.

[0058] The arc microgroove array is achieved by coordinating the dimensional parameters and movement speed of the rotating unit 101 with the movement direction and speed of the working platform 201. Furthermore, the working platform 201 can move along a first, second, and third axial directions that are perpendicular to each other, wherein the first and second axial directions are horizontal, and the third axial direction is vertical.

[0059] Since the processing line 102 is installed according to the characteristics of a cylindrical spiral line, when processing a continuous arc groove array with the second axis as the forward direction, it needs to be subject to the following conditions: the tangential direction of the rotation of the rotating unit 101 needs to be opposite to the direction of movement of the work platform 201 along the second axis, and the movement direction of the work platform 201 along the first axis is the same as the rotation direction of the processing line 102.

[0060] Comply with L>(l / l q )·X+w,V y =V T , V x =X / t, where t is the time required for the tool to rotate one circle, L is the length of the working area, l is the length of the workpiece, and l q is the length of a single-turn helix, w is the width of the workpiece, V y is the moving speed of the working platform 201 along the second axis, V x is the moving speed of the working platform 201 along the first axis, V T The linear speed at which the processing line 102 rotates.

[0061] like Figure 6As shown, in some examples, the arc groove microstructure processing device also includes a working platform 201, which is used to place the workpiece to be processed. The working platform 201 cooperates with the rotating unit 101 in a moving and rotating manner to perform coordinated movement, thereby cutting the required groove shape of the workpiece.

[0062] Furthermore, a placement structure 202 is provided on the work platform 201, and the workpiece being placed on the placement structure 202 is equivalent to the workpiece being placed on the work platform 201. Specifically, the placement structure 202 can be an electromagnetic chuck or a vacuum chuck to achieve a tight connection with the workpiece or fixture.

[0063] In some examples, the arc groove microstructure processing device further includes a support frame 203 , which is used to connect to the rotating unit 101 . It is understandable that the support frame 203 is rotatably connected to the rotating unit 101 .

[0064] In some examples, the circular arc groove microstructure processing device further includes a driving unit, which is used to drive various moving parts in the circular arc groove microstructure processing device.

[0065] Furthermore, the driving unit includes a first rotation driving unit, a moving driving unit, and a second rotation driving unit. The first rotation driving unit drives the rotating unit 101 to rotate. Considering the miniaturization design of the arc groove microstructure processing device, the first rotation driving unit is disposed inside the support frame 203.

[0066] The mobile drive unit drives the work platform 201 to move, thereby driving the workpiece to move in coordination with the movement of the rotating unit 101. The arc groove microstructure processing device also includes a base, on which the work platform 201 and support frame 203 are both disposed. The mobile drive unit can be disposed within the base. The mobile drive unit can drive the work platform 201 to move horizontally with two degrees of freedom, allowing the workpiece to move in coordination with the rotational cutting of the processing line 102, thereby forming a straight groove on the workpiece surface. Simultaneously, the mobile drive unit can drive the work platform 201 to move longitudinally with a single degree of freedom, providing feed for the workpiece and allowing it to enter the cutting range.

[0067] The second rotary drive unit drives the work platform 201 to rotate. The rotation of the work platform 201 is equivalent to the rotation of the workpiece. After the groove processing in a single direction is completed, the workpiece is rotated by a certain angle according to the desired groove shape under the action of the second rotary drive unit, facilitating further cutting on the processing line 102. In other words, the work platform 201 can move in four degrees of freedom, improving the flexibility of the processing process.

[0068] In some examples, the arc groove microstructure processing device further includes a cooling unit, which includes a water pump, a water outlet structure 301, and a liquid container. The water outlet structure 301 is connected to the base with the water outlet facing the workpiece. The water pump in the liquid container extracts liquid and delivers it to the workpiece surface through the water outlet structure 301, thereby achieving a cooling function. It is understood that by providing a discharge outlet, waste liquid can be diverted to the liquid container for recycling. Specifically, the water outlet structure 301 can be configured as a pipe.

[0069] The embodiment of the present application provides a circular arc groove microstructure processing method, which is applied to the above-mentioned circular arc groove microstructure processing device, including:

[0070] Select the workpiece material, smooth the workpiece surface and place it on the processing position of the arc groove microstructure processing device.

[0071] The workpiece material can be metal, ceramic, silicon and polymer plates. First, the workpiece is flattened by grinding, lapping and polishing, and then installed on the placement structure 202. When the placement structure 202 uses an electromagnetic suction cup or a vacuum suction cup, it is fixed by magnetic adsorption of the electromagnetic suction cup or vacuum adsorption of the vacuum suction cup.

[0072] The rotating unit 101 is installed on the arc groove microstructure processing device, the tool setting of the rotating unit 101 is performed, the initial position of the processing axis in the arc groove microstructure processing device is set, and the processing parameters are set.

[0073] Install the rotary unit 101, turn on the main power supply of the arc groove microstructure machining apparatus, and set the rotation speed of the rotary unit 101 to 10 to 100 rpm. During tool setting, set the initial position of the third axis to 0.1 mm above the point where the rotary unit 101 just contacts the workpiece. Set the initial positions of the first and second axes. In the second axis, the rotary unit 101 is positioned 2 to 5 mm from the edge of the workpiece. In the first axis, the initial position is the center of the workpiece.

[0074] After aligning the tool, set the processing parameters, set the feed depth of the third axis to 0.01 to 4 mm, the feed speed of the third axis to 0.01 to 1 mm / pass, and the tool speed to 5 to 300 rpm, rotating counterclockwise.

[0075] The moving stroke in the second axial direction is the length of the workpiece in the second axial direction plus the distance between the rotating unit 101 and the workpiece during tool setting multiplied by 2. The moving speed of the working platform 201 in the second axial direction is 7 to 50 m / min, and the moving speed of the working platform 201 in the first axial direction is 0.003 to 0.75 m / min. After adjusting the processing parameters, turn on the cooling unit to prepare for processing.

[0076] Cut the grooves in the first direction, rotate the workpiece according to the groove type to be processed, cut the grooves in the second direction, and form a groove microstructure array.

[0077] During the machining process, the machining line 102 and the workpiece move in coordination at the same linear speed. After completing the first cutting pass, the working platform 201 feeds a certain distance along the third axis, the rotating unit 101 rotates in the opposite direction, and the working platform 201 returns to the initial position according to the original motion path to complete the second cutting pass. This process is repeated. The tool line will effectively remove the workpiece material through contact with the abrasive 103, while other solid parts on the rotating unit 101 will not contact the workpiece, and finally a circular arc microgroove array of the required size is obtained.

[0078] The working platform 201 is rotated to a certain angle, the angle range is set to 10° to 180°, which is determined according to the groove requirements of the workpiece. The above steps are repeated for a second processing to obtain microstructure arrays with arc grooves of different shapes and arrangements.

[0079] After a certain processing time, the rotating unit 101 is disassembled, and the processing line 102 is disassembled on the rotating unit 101 , the rotating unit 101 is cleaned, and a new processing line 102 is installed.

[0080] Depending on the properties of the material being processed, the abrasive 103 on the surface of the processing line 102 typically wears out after 3 to 72 hours of use, resulting in a decrease in processing quality and the need to replace the processing line 102. In this case, the rotating unit 101 is removed and placed in a hot oven heated to 300°C to 500°C to melt the adhesive. The worn processing line 102 is then removed and the surface of the rotating unit 101 is cleaned with an alcohol solution and ultrasonically to remove the adhesive. A new processing line 102 is then reinstalled and attached, restoring processing capacity. Specifically, it is advisable to replace the processing line 102 after 2 to 36 hours of cutting to improve processing quality.

[0081] In some examples, when preparing microstructures on 316L stainless steel:

[0082] The cut 316L stainless steel sheet is flattened by grinding, lapping and polishing, and the stainless steel sheet is fixed to ensure stable clamping;
