[0041] The present application research and development personnel found that the keyboard area of the notebook computer upper cover needs to be punched and bulged to make the keyboard area protrude, thereby forming a height difference between the keyboard area and other areas of the upper cover, wherein the keyboard area is an area where a keyboard via hole is opened. Since the punching and bulging operation is the first step of the notebook computer upper cover forming process, after the bulging of the keyboard area, the subsequent profile cutting, bending, punching and other processes need to be processed after the bulging shape of the keyboard area is made into a profile die, which has large processing amount and high processing difficulty, and the cost of making multiple profile dies is high, thereby causing the overall processing cost of the notebook computer upper cover to be high.

[0042] Based on the above problems, the embodiments of the present application provide a notebook computer upper cover forming method, please refer to Figure 1 The notebook computer upper cover forming method comprises the following steps:

[0043] S1, performing a shaping operation on the edge of the material plate 1 to form an upper cover semi-finished product with a preset profile; the shaping operation at least includes an outline cutting operation and an edge line bending operation;

[0044] S2, performing a stamping operation on the keyboard area of the upper cover semi-finished product to form a convex 13 in the keyboard area; wherein, Figure 1 The shadow area in process S2 is the coverage area of the convex 13 formed after stamping;

[0045] S3, performing a punching operation on the upper cover semi-finished product to obtain an upper cover finished product.

[0046] Specifically, the shaping operation in step S1 is used to shape the outer shape of the material plate 1 into the preset outer shape of the notebook computer upper cover; wherein, the outline cutting operation is used to process the outer contour of the notebook computer upper cover into a preset shape by means of blanking or the like, so as to determine the basic size of the notebook computer upper cover and facilitate subsequent bending of the edges of the notebook computer upper cover; the edge line bending operation is used to bend each edge line of the notebook computer upper cover after cutting, so as to increase the structural strength of the notebook computer upper cover, and at the same time, the notebook computer upper cover can have a certain height, so as to facilitate subsequent hole opening of the side edge of the notebook computer upper cover and installation and fixation of the notebook computer upper cover to other parts of the notebook computer shell. It can be understood that the shaping operation in step S1 is not limited to the outline cutting operation and the edge line bending operation, but can also include other processing means for shaping the outer shape of the material plate 1 into the preset outer shape of the notebook computer upper cover, which is not listed here. Since the keyboard area of the notebook computer upper cover has not yet formed a convex 13 when the shaping operation in step S1 is performed, the shaping operation in step S1 can be completed without the aid of a profiling die matched with the shape of the convex 13 of the keyboard area.

[0047] The stamping operation in step S2 can make the keyboard area of the notebook computer upper cover protrude, thereby forming a height difference between the keyboard area and other areas of the notebook computer upper cover, wherein the keyboard area is the area where the keyboard via hole 15 is opened.

[0048] The punching operation in step S3 is used to open a through hole in the notebook computer upper cover by means of stamping, and the opened through hole includes the keyboard via hole 15, the touch panel hole 16, the indicator light hole, the I / O plug-in hole 17, etc.; since the keyboard area of the notebook computer upper cover has formed a convex 13 after step S2, the punching operation in step S3 needs to be completed with the aid of a profiling die matched with the shape of the convex 13 of the keyboard area.

[0049] Therefore, the notebook computer upper cover forming method provided by the embodiment improves the existing process flow, sets the stamping and bulging process of the keyboard area after the forming operation of the notebook computer upper cover outer contour, and performs the punching operation on the notebook computer upper cover after the stamping and bulging process of the keyboard area is completed. Since the bulge 13 of the keyboard area is not formed when the forming operation of the notebook computer upper cover outer contour is performed, the forming operation of the notebook computer upper cover outer contour can be completed without the aid of a profiling die matched with the shape of the bulge 13 of the keyboard area. Therefore, the operator only needs to use the profiling die in the punching operation stage. In this way, the number of profiling dies is reduced, the processing amount is reduced, and the processing difficulty is reduced, thereby reducing the overall processing cost of the notebook computer upper cover.

[0050] Optionally, referring to Figures 1 to 5 , the step S2 comprises:

[0051] S21, placing the upper cover semi-finished product on the concave die 2; the edge of the cavity 21 of the concave die 2 is surrounded by a pressing convex rib 22, and the pressing convex rib 22 abuts against the upper cover semi-finished product;

[0052] S22, performing a stamping operation on the upper cover semi-finished product by the convex die 3, so that the pressing convex rib 22 is embedded in the inside of the upper cover semi-finished product, and the keyboard area is deformed in the direction close to the cavity 21 to form the bulge 13.

[0053] When the stamping and bulging process of the keyboard area is performed after the forming operation of the notebook computer upper cover outer contour, the stamping operation causes the keyboard area to be deformed in the height direction (the height direction is the direction perpendicular to the surface of the material plate 1), which will generate a pulling force on the notebook computer upper cover towards the keyboard area, thereby possibly causing the notebook computer upper cover outer contour to shrink inwardly as a whole. Generally, the notebook computer upper cover outer contour will shrink inwardly as a whole by 0.2-0.3 mm, which will destroy the shape of the notebook computer upper cover outer contour after the forming operation is completed, so that the overall size of the notebook computer upper cover is too small, thereby reducing the structural precision and possibly causing adverse effects on the subsequent processing and assembly process of the notebook computer upper cover.

[0054] Based on the above problems, as shown in Figure 2 and Figure 4 , the pressing convex rib 22 is arranged around the edge of the cavity 21 of the concave die 2 of the stamping die when the stamping and bulging process is performed. The pressing convex rib 22 protrudes from the surface of the concave die 2 and has a closed loop shape. When the notebook computer upper cover is placed on the concave die 2, the notebook computer upper cover is arranged on the pressing convex rib 22, and the keyboard area is suspended above the cavity 21 of the concave die 2. As shown in Figure 3 and Figure 5 , the stamping operation is performed on the notebook computer upper cover by the convex die 3, so that the pressing convex rib 22 is embedded in the inside of the notebook computer upper cover, and the keyboard area is deformed in the direction close to the cavity 21 to form the bulge 13.As shown, after the notebook computer upper cover is placed, the punch 3 of the stamping die is pressed down to push the notebook computer upper cover to move downward in the direction of the cavity 21, so that the pressing convex rib 22 is embedded into the notebook computer upper cover from the lower side of the notebook computer upper cover; as the punch 3 continues to be pressed down, the punch 3 pushes the keyboard area of the notebook computer upper cover to deform in the direction of the cavity 21, at this time, the pressing convex rib 22 embedded into the notebook computer upper cover forms a local overpressure, and the pressing convex rib 22 can play a role of blocking the material outside the notebook computer upper cover (i.e. the area of the notebook computer upper cover located outside the range enclosed by the pressing convex rib 22) from moving to the inside (i.e. the area of the notebook computer upper cover located inside the range enclosed by the pressing convex rib 22); based on the overpressure blocking role, when the keyboard area is pushed into the cavity 21 by the punch 3 to form the convex bump 13, the material outside the keyboard area will not move inward under the pulling force generated by the deformation of the keyboard area, so that the overall outer contour of the notebook computer upper cover will not shrink inward, the shape of the notebook computer upper cover after the outer contour is formed will not be damaged, and thus the dimensional accuracy of the notebook computer upper cover after the forming is completed is improved.

[0055] Optionally, referring to Figures 2 to 5 , the cross-sectional area of the pressing convex rib 22 gradually increases in the pressing direction of the punch 3.

[0056] When the pressing convex rib 22 has the shape of being narrow at the top and wide at the bottom as shown in Figure 4 and Figure 5 , the structural strength of the root of the pressing convex rib 22 can be improved, the pressing convex rib 22 is reinforced, and thus the service life of the concave die 2 can be prolonged.

[0057] Optionally, referring to Figure 4 , the height H of the pressing convex rib 22 is set to be 0.18-0.22 times the thickness of the material plate 1.

[0058] Optionally, referring to Figure 4 , the width L of the pressing convex rib 22 is set to be 0.48-0.52 times the thickness of the material plate 1; wherein the width of the pressing convex rib 22 refers to the width of the narrowest part of the top end of the pressing convex rib 22.

[0059] Based on the above size settings of the pressing convex rib 22, the pressure at the pressing convex rib 22 can be ensured, so that the pressing convex rib 22 can be smoothly embedded into the notebook computer upper cover, and the pressing convex rib 22 can maintain high structural strength to prevent the service life of the concave die 2 from being reduced due to the premature damage of the pressing convex rib 22. Preferably, the height of the pressing convex rib 22 is set to be 0.2 times the thickness of the material plate 1, and the width of the pressing convex rib 22 is set to be 0.5 times the thickness of the material plate 1.

[0060] Optionally, referring to Figure 1 , the step S1 comprises:

[0061] S11, the edges of the material plate 1 are trimmed to form a base plate with a preset shape; preferably, while trimming the edges of the material plate 1, positioning through holes 14 can be punched on the material plate 1 to position the laptop cover in subsequent processing steps; wherein. Figure 1 The shaded area in intermediate process S11 is the cutting area;

[0062] S12, a bending operation is performed along the edge of the base plate in the first direction to form a bent portion 12, wherein the bent portion 12 and the main body portion 11 of the base plate form a first included angle α; wherein, as Figure 1 As shown, the shaded area of ​​process S12 is the bending area. The bending along the first direction can be a downward bending with the corresponding edge line as the axis. The first included angle α is greater than 90°, and can be set to 110°. The fixed part on the base plate other than the bending part 12 constitutes the main body part 11.

[0063] S13, a second bending operation is performed on the bent portion 12 along the first direction so that the bent portion 12 and the main body portion 11 are perpendicular to each other; wherein... Figure 1 The shaded area in intermediate process S13 is the bending area;

[0064] S14, trim the edge of the bent portion 12; specifically as follows: Figure 1 As shown, the bottom of each bent portion 12 can be cut by a punching method to obtain a laptop cover of a preset height; wherein, Figure 1 The shaded area in the intermediate process S14 is the cutting area.

[0065] This embodiment shows a specific implementation of the forming operation on the edge of the material plate 1. The bending operation on the edge of the base plate is divided into two steps: a first bending operation and a second bending operation. Compared with directly bending the bending part 12 into a way that is perpendicular to the main body part 11, the tensile force can be reduced, cracking at the corner position can be prevented, and the consistency and stability of the bending angle can be improved.

[0066] Optionally, refer to Figure 1 After step S14, the following steps are included:

[0067] S15, Upsetting operation is performed on the bent portion 12; wherein, Figure 1 The shaded area in intermediate process S15 is the part of the bending section 12 that has been thickened after the upsetting operation.

[0068] Specifically, the upsetting operation can be completed with the help of the corresponding upsetting equipment. For example, when the initial thickness of the bent part 12 is 0.8mm, the thickness of the bent part 12 can be upset to 1.1mm through the upsetting operation, so as to leave more allowance for the bent part 12, which makes it easier to carry out subsequent CNC machining processes.

[0069] Optionally, referring to Figure 1 , step S3 comprises:

[0070] S31, punching the keyboard via hole 15 on the upper cover semi-finished product; wherein, Figure 1 the shaded area in process S31 is the keyboard via hole 15 to be punched;

[0071] S32, punching the touchpad hole 16 and the indicator light hole on the upper cover semi-finished product; wherein, Figure 1 the shaded area in process S32 is the touchpad hole 16 to be punched;

[0072] S33, punching the I / O plug-in hole 17 on the bending part 12; wherein, Figure 1 the shaded area in process S33 is the I / O plug-in hole 17 to be punched.

[0073] Optionally, referring to Figure 1 , after step S3, comprising:

[0074] S4, performing a flatness shaping operation on the upper cover semi-finished product after punching.

[0075] After the above-mentioned multiple processing procedures in the embodiment, the flatness of the notebook computer upper cover is poor, at this time, the notebook computer upper cover can be subjected to a flatness shaping operation by the shaping column, and the height difference between the multiple shaping columns is used to make the flatness of the notebook computer upper cover meet the requirements, and finally the upper cover finished product is obtained.

[0076] For example, the complete forming procedure of the notebook computer upper cover described in the above embodiment, wherein the punching operation in process steps S31, S32 and S33 needs to be completed by means of a profiling die matched with the shape of the convex hull 13 of the keyboard area, and the notebook computer upper cover outer contour forming operation in process steps S11, S12, S13, S14 and S15 can be completed without the profiling die matched with the shape of the convex hull 13 of the keyboard area; that is, only three sets of profiling dies corresponding to steps S31, S32 and S33 are needed to realize the overall forming of the notebook computer upper cover. If the existing forming method is adopted, the profiling die needs to be adopted for the above-mentioned steps S11, S12, S13, S14, S15, S31, S32 and S33, that is, a total of eight sets of profiling dies are needed to complete the overall forming of the notebook computer upper cover according to the prior art. It can be seen that the notebook computer upper cover forming method of the present application saves at least five sets of profiling die opening costs compared with the prior art.

[0077] Correspondingly, the application also provides a notebook computer upper cover made by the notebook computer upper cover forming method of any of the above embodiments. Since the notebook computer upper cover adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0078] Correspondingly, the application also provides a notebook computer comprising the notebook computer upper cover of any of the above embodiments. Since the notebook computer adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0079] It should be noted that other contents of the notebook computer upper cover forming method, the notebook computer upper cover and the notebook computer disclosed by the application can be referred to the prior art, which will not be repeated here.

[0080] The above is only an optional embodiment of the application, and does not limit the patent scope of the application.
