Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic device processing, in particular to a shell processing method, a shell and an electronic device. BACKGROUND

[0002] With the continuous development of science and technology, people's requirements for the hand feeling of the shell of electronic devices are getting higher and higher. At present, the shells of many electronic devices are made of metal, and the metal shells have better texture and are more wear-resistant than plastic, and have a longer service life. The existing metal shell processing steps usually provide a metal plate, forge and press to form a stamping material, and then perform cutting, hole opening, polishing and other processes through CNC to form the final product.

[0003] In the cutting process, the stamping material needs to be positioned and then cut. When the shell is a plane, the stamping material can be accurately positioned and detected using a clamp and a probe. However, many electronic devices such as notebook computers have an arc-shaped part around the shell to improve the hand feeling, and a chamfered plane needs to be cut around the arc-shaped part to make the shell more beautiful. For cutting a plane around the arc-shaped part, since it is not easy to set a detection point to detect the height of the arc-shaped part, the existing technology is to place the stamping material on the clamp base, and then press the stamping material against the base with a cover plate to fix it on the base and directly cut it. At this time, as long as the arc surface of the arc-shaped part has a deviation, the final product will be directly unqualified, so the yield of the shell is not high.

[0004] Therefore, those skilled in the art urgently need a new shell processing method to solve the technical problems existing in the prior art and improve the yield of the shell. SUMMARY

The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0044] The shell processing method of the embodiment of the present application is used for processing a stamping blank to obtain the shell. The shell is made of metal material, which can be aluminum alloy, titanium alloy, stainless steel or other metal material.

[0045] As shown in Figure 1 , the shell processing method of the embodiment of the present application comprises the following steps:

[0046] Step S10: providing a stamping blank 100.

[0047] In step S10, as shown in Figures 2-3 , Figure 3 is a sectional view of the stamping blank 100 along A-A direction of the embodiment of the present application. The stamping blank 100 comprises a main body part 10, an arc-shaped part 20 and a skirt part 30. The main body part 10, the arc-shaped part 20 and the skirt part 30 are integrally formed, the arc-shaped part 20 is gradually extended upward from the circumference of the main body part 10 to form, and the skirt part 30 is extended outward from the circumference of the arc-shaped part 20 to form. The main body part 10 is a flat plate, the main body part 10 and the arc-shaped part 20 form an inner cavity 11 with the opening upward, and the side where the inner cavity 11 is located is the front side, and the side opposite to the front side is the back side. The main body part 10 is a flat plate; the arc-shaped part 20 is formed on the circumference of the main body part 10 and is annular; and the skirt part 30 is formed on the circumference of the arc-shaped part 20 and is annular. The skirt part 30 is arranged in parallel with the main body part 10, the skirt part 30 comprises an upper surface 31 on the front side of the stamping blank 100 and a lower surface 32 on the back side of the stamping blank 100, and the upper surface 31 and the lower surface 32 are both flat surfaces. It should be noted that the upper surface 31 and the lower surface 32 are only for the relative position relationship in a certain specific placement state. For example, in the state of the front side upward, the upper surface 31 is upward and the lower surface 32 is downward; if the back side is upward, the upper surface 31 is downward and the lower surface 32 is upward.

[0048] Specifically, the stamping blank 100 is obtained by stamping a flat plate to be processed. Therefore, before step S10, the stamping blank 100 needs to be obtained, and the stamping blank 100 is obtained through step S0.

[0049] Specifically, step S0: obtaining a flat plate to be processed, and stamping the flat plate to be processed into the stamping blank 100. In step S0, the flat plate to be processed is placed on a jig, and a forging press is used to stamp the flat plate to be processed, wherein the jig has the same shape as the stamping blank 100, and the flat plate to be processed is deformed under the pressure of the forging press to obtain the stamping blank 100. Since the stamping blank 100 is formed by stamping, the thickness accuracy is very high, and the thickness error can not cause the problem of low yield in the subsequent processing steps. Only the positioning accuracy of the stamping blank 100 needs to be considered.

[0050] Step S20: detecting the height of the upper surface 31, and cutting the arc-shaped part 20 according to the detection result to cut the positioning surface 21 on the front surface of the arc-shaped part 20.

[0051] In step S20, the stamping blank 100 is placed on a processing jig, and a probe is used to detect the height of the upper surface 31. Since the upper surface 31 is a plane, the probe can accurately detect the height of the upper surface 31. Compared with the prior art scheme of positioning the stamping blank 100 by using a jig and then directly processing, the prior art scheme highly depends on the accuracy of the jig and the arc-shaped part 20. The present scheme detects the height of the upper surface 31, controls the first cutter to move around the circumference of the arc-shaped part 20 according to the detection result, cuts the arc-shaped part 20, and cuts the positioning surface 21 on the front surface of the arc-shaped part 20, as shown in FIG. 2B. Figure 4 Figure 4 FIG. 2C is a sectional view of the stamping blank 100 along the A-A direction after the positioning surface 21 is cut according to an embodiment of the present application. In the present embodiment, the first cutter is a T-shaped cutter, which cuts the arc-shaped part 20 by rotating, and then moves along a preset path, specifically, cuts the side facing upward when the front surface of the arc-shaped part 20 faces upward, to obtain the positioning surface 21. The positioning surface 21 is used for accurate detection in the subsequent steps and improves the cutting accuracy. The positioning surface 21 will be removed in the subsequent steps, and the final shell 100 does not have the positioning surface 21.

[0052] Specifically, step S20 includes the following steps:

[0053] Step S201: placing the stamping blank 100 with the front surface facing upward, and using a probe to detect the height of a first detection point of the upper surface 31.

[0054] ​In step S201, the stamping material 100 is fixed on a processing fixture with the front face upward, and the height of the first detection point on the upper surface 31 is detected by a probe. The probe can be a contact height gauge. The detection points need to be preset in advance, and the specific positions can be set according to the actual situation. In addition, a plurality of detection points need to be set to detect the height of each detection point. By setting a plurality of detection points, the detection can be more accurate. For example, a detection point is set every interval along the length direction of the upper surface 31.

[0055] Step S202: calculating a first compensation amount according to the height of the first detection point.

[0056] In step S202, the first compensation amount is calculated according to the detection results of each first detection point. The calculation of the first compensation amount needs to set a zero point, and then the height of each first detection point is detected to calculate the deviation value of each first detection point from the zero point to adjust the height of the first tool. For example, the height of a certain first detection point is +0.05mm, and since the tool head of the first tool is above the stamping material 100, the first tool needs to move upward by 0.05mm at this first detection point to prevent cutting too deep.

[0057] Step S203: controlling the first tool to move along the circumference of the arc-shaped part 20 according to the first compensation amount to cut the arc-shaped part 20 to cut the positioning surface 21 on the front face of the arc-shaped part 20.

[0058] In step S203, the movement path of the first tool is preset, and the movement path of the first tool is adjusted according to the first compensation amount to prevent cutting too deep or too shallow, greatly improving the precision of cutting and making the cut positioning surface 21 more accurate.

[0059] Step S30: detecting the height of the lower surface 32, and cutting the skirt part 30 according to the detection result to remove the skirt part 30 to cut the inclined surface 22 connected with the positioning surface 21 on the circumference of the arc-shaped part 20.

[0060] In step S30, the punch blank 100 is placed on a machining jig, and a probe is used to detect the height of the lower surface 32. Since the lower surface 32 is planar, the probe can accurately detect the height of the lower surface 32. Compared with the prior art solution of using a jig to position the punch blank 100 and then directly machining the punch blank 100, the prior art solution highly depends on the accuracy of the jig and the curved portion 20. The present solution detects the height of the lower surface 32, controls the second cutter to move around the periphery of the skirt portion 30 according to the detection result, cuts the skirt portion 30, removes the skirt portion 30, and cuts the inclined surface 22 connected to the positioning surface 21 around the periphery of the curved portion 20. In the present embodiment, the second cutter is a T-shaped cutter. The second cutter cuts the skirt portion 30 by rotating, and then controls the second cutter to move along a preset path, thereby obtaining the inclined surface 22. As shown in FIG. 3, Figure 5 Figure 5 FIG. 4 is a sectional view of the punch blank 100 along the A-A direction after the inclined surface 22 is cut by the present solution. Specifically, the head of the second cutter is a circular truncated cone. The head of the second cutter is below the punch blank 100 and cuts the skirt portion 30 from the outside of the skirt portion 30 to the inside of the skirt portion 30, thereby gradually removing the skirt portion 30. The angle between the inclined surface 22 and the positioning surface 21 is greater than 90°.

[0061] Specifically, step S30 includes the following steps.

[0062] Step S301: The punch blank 100 is placed with the reverse surface facing upward, and a probe is used to detect the height of a second detection point of the lower surface 32.

[0063] In step S301, the punch blank 100 is placed with the reverse surface facing upward, and a probe is used to detect the height of a first detection point of the upper surface 31. Similar to step S201, the probe can be a contact height gauge. The detection points need to be preset in advance, and the specific positions can be set according to actual conditions. In addition, a plurality of detection points are generally needed to detect the heights of all the detection points. The plurality of detection points can make the detection more accurate.

[0064] Step S302: A second compensation amount is calculated according to the height of the second detection point.

[0065] ​In step S302, a second compensation amount is calculated according to the detection result of each second detection point. The calculation of the second compensation amount also needs to set a zero point, and then the height of each second detection point is detected in sequence, and the deviation value of each second detection point from the zero point is calculated to adjust the height of the second tool. For example, the height of a certain second detection point is -0.05mm, and since the tool head of the second tool is below the punched material 100, the second tool needs to move downward by 0.05mm at this second detection point to prevent cutting too deep.

[0066] Step S303: The second tool is controlled to move along the circumference of the skirt portion 30 according to the second compensation amount to cut the skirt portion 30 until the skirt portion 30 is removed, and an inclined surface 22 connected to the outward side of the positioning surface 21 is cut on the circumference of the arc-shaped portion 20.

[0067] In step S303, the movement path of the second tool is preset, and the movement path of the second tool is adjusted according to the second compensation amount to prevent cutting too deep or too shallow, greatly improving the precision of cutting and enabling the cut positioning surface 21 to be more accurate. The inward side of the inclined surface 22 coincides with the outward side of the positioning surface 21.

[0068] Step S40: The height of the positioning surface 21 is detected, and the positioning surface 21 is cut according to the detection result to form a finished surface 23 parallel to the positioning surface 21 on the circumference of the arc-shaped portion 20 to obtain the shell 100.

[0069] In step S40, the punched material 100 is placed on a machining jig, and a probe is used to detect the height of the positioning surface 21. Since the positioning surface 21 is a plane, the probe can accurately detect the height of the positioning surface 21. According to the detection result, the third tool is controlled to move on the circumference of the arc-shaped portion 20 to cut the positioning surface 21, and finally the positioning surface 21 is completely removed to form a finished surface 23 parallel to the positioning surface 21 on the circumference of the arc-shaped portion 20. As shown in Figure 6 , Figure 6 A cross-sectional view of the punched material 100 along the A-A direction after the finished surface 23 is cut by the embodiment of the present application. At this time, the punched material 100 has been machined, and therefore Figure 6 is also a cross-sectional view of the shell 100 of the embodiment.

[0070] The height difference between the positioning surface 21 and the finished surface 23 is 0.25mm±1%. In this embodiment, the third tool is a T-shaped tool. Specifically, the shape of the third tool is the same as that of the first tool but the size of the third tool is larger than that of the first tool, and the tool head of the third tool is above the punched material 100.

[0071] Specifically, the step S40 comprises the following steps:

[0072] Step S401: Turn the stamping blank 100 face up, and use a probe to detect the height of the third detection point of the positioning surface 21.

[0073] In step S401, the stamping blank 100 is again turned face up and fixed on a machining jig, and a probe is used to detect the height of the third detection point of the positioning surface 21. The probe can be a contact height gauge. The detection points need to be preset in advance, and the specific position can be set according to the actual situation. In addition, a plurality of detection points need to be set to detect the height of all detection points respectively. By setting multiple detection points, the detection can be more accurate. Specifically, before step S401, it also includes: using a brush to polish the connection between the inclined surface 22 and the positioning surface 21 to remove burrs. By removing the burrs, it can further prevent the height detected by the probe from being inaccurate due to the existence of burrs.

[0074] Step S402: Calculate a third compensation amount according to the height of the third detection point.

[0075] In step S402, a third compensation amount is calculated according to the detection result of each third detection point. The calculation of the third compensation amount also needs to set a zero point, and then the height of the third detection point is detected in sequence, and the deviation value of each third detection point from the zero point is calculated to adjust the height of the third tool. For example, the height of a certain third detection point is -0.05mm, and since the tool head of the third tool is above the stamping blank 100, the third tool needs to be moved downward by 0.05mm at this third detection point to prevent the cutting from being too shallow.

[0076] Step S403: According to the third compensation amount, control the third tool to move along the length direction of the positioning surface 21, cut the positioning surface 21, and form a finished surface 23 parallel to the positioning surface 21 on the circumference of the front surface of the arc-shaped part 20.

[0077] In step S403, the movement path of the third tool is preset, and the movement path of the third tool is adjusted according to the third compensation amount to prevent the cutting from being too deep or too shallow, greatly improving the precision of the cutting and making the cut finished product more accurate.

[0078] Through the above steps, the machining of the stamping blank 100 can be completed, and the shell 100 is obtained. As shown in Figure 7 Figure 7 ​A structural schematic diagram of a shell 100 according to an embodiment of the present application. The shell 100 according to the embodiment includes a main body part 10 and an arc-shaped part 20 gradually extending upward from the periphery of the main body part 10. The main body part 10 and the arc-shaped part 20 enclose an inner cavity 11 with an opening facing upward, as shown. The side where the inner cavity 11 is located is the front side, and the side opposite to the front side is the back side. The shell 100 is integrally formed. The side of the arc-shaped part 20 facing upward includes a finished surface 23 and an inclined surface 22 located outside the finished surface 23. Figure 1 It should be noted that the shell 100 can also be subjected to other processing, such as drilling and opening on the main body part 10, and the like. This is not limited herein.

[0079] It should be noted that the shell 100 can also be subjected to other processing, such as drilling and opening on the main body part 10, and the like. This is not limited herein.

[0080] The shell processing method according to the embodiment of the present application adds an integrally formed skirt part 30 to the periphery of the arc-shaped part 20. In the subsequent cutting step, the upper surface 31 and the lower surface 32 of the skirt part 30 are used for accurate positioning, without the need to rely on the arc-shaped part 20 tightly abutting against a jig. There is also no problem of difficulty in detecting the height of the arc surface of the arc-shaped part 20. The upper surface 31 is used to cut a positioning surface 21, the lower surface 32 is used to cut the inclined surface 22 and remove the skirt part 30, and finally the positioning surface 21 is used to cut the finished surface 23. Since the upper surface 31 and the lower surface 32 are both flat surfaces, the detection is very accurate, thereby greatly improving the cutting accuracy and effectively improving the yield of the shell 100.

[0081] The embodiment of the present application also provides an electronic device including the shell 100 obtained by the above processing method. The electronic device includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a smart watch, and the like.
