Abstract

[0002] At present, in the processing of the outer frame of electronic products (such as mobile phones or tablet computers), the outer frame is positioned on a jig, and the front side of the outer frame after positioning faces upward and the back side faces downward. The inner and outer sides of the front and back sides of the outer frame all have edges. During processing, fillets or chamfers need to be processed at the four edges. Traditional processing methods all use rotary tools, that is, the edges are cut by the rotation of the tool to form fillets or chamfers, but the rotary tool is prone to burrs when it rotates rapidly, resulting in low processing quality. In addition, since the outer frame is positioned on the jig, there is a problem of insufficient space when processing the back side of the outer frame.

[0052] The technical solution of the present application will be described below in conjunction with the drawings in the implementation modes of the present application. Obviously, the described implementation modes are only part of the implementation modes of the present application, rather than all the implementation modes.
[0053] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered.

[0054] In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. The term "perpendicular" is used to describe an ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular between the two components. For example, in combination with numerical descriptions, perpendicularity may refer to the angle between two straight lines being in the range of 90°±10°, perpendicularity may also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicularity may also refer to the angle between a straight line and a plane being in the range of 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.
[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.
[0056] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0057] See also Figure 1 and Figure 2 In one embodiment of the present application, a tool head 100 is provided for processing a rounded corner or a chamfer on an edge 300 of a workpiece 200. The tool head 100 includes a tool head 10 and a tool handle 20. The tool head 10 is disposed on the tool handle 20. The tool head 10 can translate or rotate in space with the tool handle 20. The tool head 10 processes the edge 300 by moving along the tangent direction of the contour trajectory of the edge 300. The tool head 10 does not process the edge 300 by high-speed rotation.
[0058] See also Figures 3 to 7In some embodiments, the cutter head 10 includes a first surface 11 and a second surface 12. The first surface 11 and the second surface 12 are respectively arranged on opposite sides of the cutter head 10 along the thickness direction (X direction). The cutter head 10 is provided with a first groove 10a. The first groove 10a penetrates the first surface 11 and the second surface 12. The first groove 10a also penetrates one side of the cutter head 10 along the height direction (Z direction). The cutter head 10 forms a first blade 13 at the edge of the first surface 11 and the first groove 10a. When the cutter head 10 processes the edge 300, the first groove 10a is used to accommodate the edge 300 so that the edge 300 contacts the first blade 13. Then the cutter head 10 moves so that the first blade 13 moves along the tangent direction of the contour trajectory of the edge 300. The moving first blade 13 is used to cut the edge 300 so that the edge 300 is processed into a rounded corner or chamfer. Since the cutter head 10 does not need to rotate at high speed, the cutter head 10 is more convenient to process in a limited space, which can avoid adding additional working steps and improve the processing efficiency.
[0059] It is understandable that whether the edge 300 is processed into a rounded corner or a chamfer depends on the shape of the first edge 13. If the first edge 13 is straight, a chamfer is processed, and if the first edge 13 is arc-shaped, a rounded corner is processed. In some embodiments, the shape of the first edge 13 is an arc to process a rounded corner on the edge 300, because a rounded corner is easier to avoid burrs than a chamfer, which is more conducive to improving the processing quality.
[0060] In some embodiments, the through area of the first groove 10a gradually increases from the first surface 11 to the second surface 12 (X direction). When the first blade 13 processes the edge 300, because the first surface 11 faces the moving direction of the cutter head 10, the through area of the first groove 10a gradually increases in the opposite direction of the movement of the cutter head 10, so that the first groove 10a can play a role in facilitating chip removal, thereby reducing the generation of burrs on the edge 300, thereby improving the processing quality.
[0061] In some embodiments, the workpiece 200 is a frame of a mobile phone, such as Figure 1 and Figure 2 As shown, the outer frame of the mobile phone has a front side 210 and a back side 220, the inner side of the front side 210 has a front inner edge 310, the outer side of the front side 220 has a front outer edge 320, the inner side of the back side 220 has a back inner edge 330, and the outer side of the back side 220 has a back outer edge 340, that is, the workpiece 200 has four edges 300, namely, the front inner edge 310, the front outer edge 320, the back inner edge 330 and the back outer edge 340, and all of them need to be processed with rounded corners or chamfers. When the cutter head 10 has only one first blade 13, the cutter head 10 can use the first blade 13 to process the front inner edge 310, the front outer edge 320, the back inner edge 330 and the back outer edge 340 in sequence, and the processing of all edges 300 of the workpiece 200 can be completed.
[0062] In some embodiments, the cutter head 10 forms two first edges 13 at the edges of the first surface 11 and the first groove 10a, and the two first edges 13 are arranged opposite to each other along the width direction (Y direction) of the cutter head 10. During processing, the first groove 10a can receive the front side 210 or the back side 220 of the workpiece 200, so that the two opposite first edges 13 contact the front inner edge 310 and the front outer edge 320 respectively at the same time, or contact the back inner edge 330 and the back outer edge 340 respectively at the same time, so that the cutter head 10 can cut the front inner edge 310 and the front outer edge 320 at the same time, or cut the back inner edge 330 and the back outer edge 340 at the same time, so as to improve the processing efficiency.
[0063] It should be noted that, as an illustrative example, during processing, the workpiece 200 is horizontally positioned on the fixture, the front side 210 and the back side 220 are horizontally arranged, the front side 210 faces upward, the back side 220 faces downward, and the first groove 10a passes through the upper side of the tool head 10, that is, the first edge 13 is arranged upward. It is easy to understand that the upward first edge 13 is more convenient for processing the downward back side 220, and the upward first edge 13 needs to be turned upside down by the tool 100 before it can process the upward front side 210.
[0064] In some embodiments, a second groove 10b is further provided on the side of the cutter head 10 away from the first groove 10a, that is, the first groove 10a and the second groove 10b are respectively provided on opposite sides of the cutter head 10 along the height direction (Z direction), and the second groove 10b penetrates the first surface 11 and the second surface 12. The second groove 10b also penetrates the side of the cutter head 10 away from the first groove 10a along the height direction (Z direction), that is, the second groove 10b penetrates the lower side of the cutter head 10, and the cutter head 10 forms two second edges 14 at the edges of the second surface 12 and the second groove 10b. The two second edges 14 are arranged opposite to each other along the width direction (Y direction) of the cutter head 10, and the two second edges 14 are arranged downward, and the second edges 14 are used for processing the edge 300. The penetration area of the second groove 10b gradually increases from the second surface 12 to the first surface 11 to facilitate chip removal. Since the first edge 13 and the second edge 14 are respectively arranged on the upper and lower sides of the tool head 10, during processing, the upward first edge 13 can be used to process the downward back side 220, and the downward second edge 14 can be used to process the upward front side 210, without turning the tool 100 upside down, thereby simplifying the control of the tool 100 and improving processing efficiency.
[0065] For example, see Figure 8In some embodiments, when the workpiece 200 is processed into an outer frame, if the outer frame has a section 230, that is, the outer frame is not in a closed ring shape, and the section 230 is perpendicular to the front side 210 and the back side 220, then the cutting method can be: the cutter head 10 starts from one end of the front side 210 and moves toward the other end along the contour trajectory of the workpiece 200 (for example, clockwise), while moving, the front inner edge 310 and the front outer edge 320 are simultaneously cut through the two downward second blades 14, when the front side 210 is cut, the cutter head 10 descends along the section 230, and then moves in the opposite direction along the contour trajectory of the workpiece 200 (for example, counterclockwise), while moving in the opposite direction, the back inner edge 330 and the back outer edge 340 are simultaneously cut through the two upward first blades 13 until the back side 220 is cut. This cutting method can make the movement of the cutter head 10 smoother and reduce the number of pauses of the cutter head 10 during the cutting process. Moreover, compared with the case where the cutter head 10 is only provided with the first edge 13, this cutting method can prevent the cutter head 10 from flipping up and down, thereby simplifying the control of the cutter head 10 and further improving the processing efficiency.
[0066] In some embodiments, Fig.11 As shown, the shapes of the front inner edge 310 and the front outer edge 320 to be processed are mirror-symmetrical, and the shapes of the back inner edge 330 and the back outer edge 340 to be processed are mirror-symmetrical. At this time, a symmetry plane P is defined to be perpendicular to the first surface 11 and the second surface 12. The cutter head 10 moves in a direction parallel to the symmetry plane P during processing. The two first blades 13 are arranged mirror-symmetrically along the symmetry plane P, and the two second blades 14 are arranged mirror-symmetrically along the symmetry plane P, so that the two first blades 13 can process the back inner edge 330 and the back outer edge 340 of mirror-symmetrical, and the two second blades 14 can also process the front inner edge 310 and the front outer edge 320 of mirror-symmetrical.
[0067] Further optionally, in some embodiments, as Fig.12 As shown, based on the mirror symmetry between the front inner edge 310 and the front outer edge 320, and the mirror symmetry between the back inner edge 330 and the back outer edge 340, the front 210 and the back 220 of the workpiece 200 are symmetrical in top and bottom. At this time, a symmetry point T is defined to be located on the symmetry plane P, and the two first blades 13 are rotated 180 degrees around the axis A passing through the symmetry point T and perpendicular to the symmetry plane P to coincide with the two second blades 14, so that the processed front 210 and back 220 are symmetrical in top and bottom, and the tool head 10 can directly perform counterclockwise processing after clockwise processing, without the need to flip the tool head 10, so as to improve processing efficiency.
[0068] In some embodiments, the cutter head 10 forms a chip removal surface 15 in the first groove 10a, and the chip removal surface 15 is provided between the first surface 11 and the second surface 12. The first edge 13 is formed at the connection between the chip removal surface 15 and the first surface 11. The chip removal surface 15 facilitates the removal of the chips generated during the cutting process of the first edge 13, so that the chips are discharged toward the rear of the movement of the cutter head 10, thereby avoiding the chips from splashing and improving the cutting quality. Further optionally, in an embodiment where the cutter head 10 has a second edge 14, the second edge 14 is formed at the connection between the chip removal surface 15 and the second surface 12, and the chip removal surface 15 facilitates the removal of the chips generated during the cutting process of the second edge 14.
[0069] See also Fig. 9 In some embodiments, the moving direction of the first blade 13 during processing is the X direction, and there is a clearance angle w between the chip removal surface 15 and the X direction. The size of the clearance angle w is set to: ensure the strength of the first blade 13 and ensure that sufficient space is provided for efficient chip removal. In addition, in some embodiments, the contour trajectory of the edge 300 is a partial rectangle with rounded corners, and the contour of the edge 300 is a 90-degree arc at the rounded corner. Therefore, when the cutter head 10 cuts along the arc, the setting of the size of the clearance angle w must also ensure that the chip removal surface 15 does not accidentally touch the edge 300, thereby avoiding the cutter head 10 squeezing the edge 300 and causing over-cutting of the material. Therefore, the back angle w should be neither too large nor too small. If the back angle w is too large, the thickness between the chip removal surface 15 and the first surface 11 will be too small, thereby weakening the strength of the first blade 13, and causing vibration marks on the machined surface during production; if the back angle w is too small, the gap between the chip removal surface 15 and the edge 300 will be too small, resulting in insufficient chip removal space and difficulty in chip removal. Not only that, it will also cause the chip removal surface 15 to accidentally touch the edge 300 when the cutter head 10 is cutting along an arc, thereby causing the cutter head 10 to squeeze the edge 300 and over-cut the material.
[0070] As an illustrative example, based on experimental experience, the range of the back angle w is greater than or equal to 45 degrees and less than or equal to 50 degrees, which can ensure the strength of the first edge 13, ensure sufficient space for efficient chip removal, and prevent the chip removal surface 15 from accidentally touching the edge 300 to avoid overcutting of the material.
[0071] In some embodiments, Figures 2 to 4 As shown, the cutter head 10 further forms a flat bottom surface 16 in the first groove 10a. The flat bottom surface 16 is connected to the chip removal surface 15 and is arranged between the first surface 11 and the second surface 12. The flat bottom surface 16 is parallel to the X direction. During cutting, there is a gap between the flat bottom surface 16 and the front side 210 or the back side 220 of the workpiece 200. On the basis of ensuring that there is enough cutting space for the first groove 10a and the first groove 10b, the flat bottom surface 16 is beneficial to ensuring the strength of the cutter head 10 and avoiding vibration marks due to excessive weakness.
[0072] In some embodiments, the first surface 11 is parallel to the second surface 12, so that the thickness of the tool head 10 along the X direction remains constant in the portion where the first groove 10a and the second groove 10b are not provided, thereby ensuring the strength of the tool head 10 and avoiding vibration marks caused by too weak strength.
[0073] In some embodiments, the axis of the tool handle 20 is parallel to the first surface 11 and the second surface 12, and the tool head 10 is connected to the circumference of the tool handle 20, that is, the width direction (Y direction) of the tool head 10 is parallel to the radial direction of the tool handle 20, and the height direction (Z direction) of the tool head 10 is parallel to the axial direction of the tool handle 20, so that it is easier for the tool handle 20 to control the translation of the tool head 10 in the XY plane, the lifting and lowering along the Z direction, and the rotation around the Z direction. As an illustrative example, the tool head 10 is a synthetic diamond (Process Control Diamond, referred to as PCD), and the tool head 10 and the tool handle 20 are connected by welding.
[0074] In one embodiment of the present application, a processing device 400 is also provided. Figure 1 As shown, the processing equipment 400 includes a transfer mechanism 410, a fixture (not shown) and a tool 100 in any of the above embodiments. The end of the tool handle 20 away from the tool head 10 is arranged on the transfer mechanism 410, the fixture is used to position the workpiece 200, and the transfer mechanism 410 is used to drive the tool head 10 to translate in the XY plane, lift in the Z direction, and rotate around the Z direction through the tool handle 20.
[0075] In some embodiments, Fig.10 As shown, the contour trajectory of the edge 300 is a partial rectangle with rounded corners, and the contour of the edge 300 is a 90-degree arc at the rounded corner. Therefore, when the cutter head 10 cuts along the arc, the transfer mechanism 410 drives the cutter head 10 to feed along the X direction and the Y direction, and at the same time, drives the cutter head 10 to rotate around the Z direction by a corresponding angle, so that when the feed motions of the cutter head 10 along the X direction and the Y direction are superimposed, the angle of the cutter head 10 increases at the same time, thereby ensuring that the first blade 13 and the second blade 14 always cut the edge 300 along the tangent direction of the contour trajectory of the edge 300, thereby ensuring the cutting quality, making the processed cutting surface higher and brighter, and avoiding over-cutting or under-cutting of the material.
[0076] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
