Description

Technical Field

[0001] This application belongs to the field of mobile phone mid-frame processing technology, and particularly relates to high-strength lightweight mobile phone mid-frames and their processing methods. Background Technology

[0002] The mid-frame of a mobile phone is located between the screen and the back cover. It is a key framework that supports and protects the internal components of the phone. Its outer frame connects the edge of the screen and the edge of the back cover, while its inner frame carries the motherboard, battery, camera, and various sensors. The mid-frame of a mobile phone is generally made of metal or plastic.

[0003] The mainstream processing methods for mobile phone mid-frames currently include die casting + CNC machining and full CNC machining. Although the full CNC machining method produces better product quality, it has a very low material utilization rate, resulting in high costs. The existing die casting + CNC machining method often uses fixed processes. If problems occur during the die casting process and cause local defects in the processed parts, it is very likely to affect the quality of the finished mobile phone mid-frame. Therefore, the existing mobile phone mid-frame processing methods have the problem of low yield rate of mobile phone mid-frames. Summary of the Invention

[0004] This application provides a high-strength, lightweight mobile phone mid-frame and its processing method, which can solve the problem of low yield rate of mobile phone mid-frames produced by existing mobile phone mid-frame processing methods.

[0005] In a first aspect, embodiments of this application provide a method for processing a high-strength, lightweight mobile phone mid-frame. This method is applied to the debugging stage of mobile phone mid-frame processing and is divided into two stages: die casting and cutting. The method includes: A completely symmetrical blank to be processed is obtained in the die casting stage; wherein, the completely symmetrical blank to be processed means that the front and back sides of the blank to be processed are completely symmetrical, and the upper and lower parts of the same side are also completely symmetrical. The rough blank to be processed is subjected to quality inspection to obtain a rough blank quality report; wherein, the rough blank quality report includes quality scores for each local area; The cutting direction of the rough blank to be processed is selected based on the rough blank quality report; The cutting path is determined according to the cutting direction, and cutting is performed. After cutting is completed, the finished product is inspected and a finished product quality report is generated; the finished product quality report is used to reflect the type and location of defects in the finished product; When the number of times the same defect appears in multiple finished product quality reports exceeds a first threshold, the cutting stage or die-casting stage is adjusted according to the finished product quality reports.

[0006] The technical solutions described in this application embodiment have at least the following technical effects: The high-strength, lightweight mobile phone frame processing method provided in this application firstly obtains a completely symmetrical blank during the die-casting stage. This step involves obtaining a completely symmetrical blank through die-casting. Secondly, the blank undergoes quality inspection to obtain a blank quality report. This step involves inspecting each die-cast blank to determine the location of defects. Subsequently, the cutting direction of the blank is selected based on the blank quality report. This step uses the blank quality report, which reflects the overall and local quality of the blank, to determine the cutting direction during the cutting process. The aim is to select a cutting direction that removes the most defects, thus improving the quality of the finished mobile phone frame. Then, the cutting path is determined based on the cutting direction, and cutting is performed. This step improves cutting accuracy and product quality. Finally, after cutting, the finished product undergoes quality inspection, and a finished product quality report is generated. This step involves detailed inspection of the finished product after cutting, resulting in a finished product quality report that reflects the type and location of defects in the finished mobile phone frame. Finally, when the number of times the same defect appears in multiple finished product quality reports exceeds the first threshold, adjustments are made to the cutting or die-casting stage based on the finished product quality reports. This step first determines whether there are regularly recurring defects. If so, corresponding adjustments are made to the die-casting mold, which helps improve the quality of the finished phone frame. In this method, a perfectly symmetrical blank is first die-cast in the die-casting stage. Then, the overall quality of the blank determines the cutting direction. Finally, the quality of the finished product determines how to adjust the cutting or die-casting stage. This method balances the high material utilization of the die-casting + CNC machining method with the high precision of the full CNC machining method, reducing the focus on die-casting quality. Therefore, it can solve the problem of low yield rates in existing phone frame processing methods.

[0007] Secondly, embodiments of this application provide a high-strength, lightweight mobile phone frame, which is processed by the method described in any of the first aspects above.

[0008] Thirdly, embodiments of this application provide a high-strength, lightweight mobile phone mid-frame processing equipment. This equipment is applied to the debugging stage of mobile phone mid-frame processing and is divided into two stages: die casting and cutting. The equipment includes: A die-casting apparatus for obtaining a completely symmetrical blank to be processed during the die-casting stage; wherein, the completely symmetrical blank to be processed means that the front and back sides of the blank to be processed are completely symmetrical, and the upper and lower parts of the same side are also completely symmetrical. A quality inspection device is used to inspect the rough blank to be processed and obtain a rough blank quality report; wherein, the rough blank quality report includes quality scores for each local area; A control device for selecting the cutting direction of the rough blank to be processed based on the rough blank quality report; A cutting device is used to determine the cutting path according to the cutting direction and to perform cutting; The quality inspection device is also used to inspect the finished product after cutting and generate a finished product quality report; wherein the finished product quality report is used to reflect the type and location of defects in the finished product; The control device is also used to adjust the cutting stage or the die-casting stage according to the finished product quality reports when the number of times the same defect appears in multiple finished product quality reports is greater than a first threshold.

[0018] In related technologies, the mainstream processing methods for mobile phone mid-frames are die casting + CNC machining and full CNC machining. Although the full CNC machining method produces better product quality, it has a very low material utilization rate, resulting in high costs. The existing die casting + CNC machining method often uses fixed processes. If problems occur during the die casting process, resulting in local defects in the processed parts, it is very likely to affect the quality of the finished mobile phone mid-frame. Therefore, the existing mobile phone mid-frame processing methods have the problem of low yield rate of mobile phone mid-frames.

[0019] To address the aforementioned problems, this application provides a method for processing a high-strength, lightweight mobile phone mid-frame. In this method, firstly, a perfectly symmetrical blank is obtained during the die-casting stage. This step involves obtaining a perfectly symmetrical blank through die-casting. Secondly, the blank is quality inspected to obtain a blank quality report. This step involves inspecting each die-cast blank to determine the location of defects. Subsequently, the cutting direction of the blank is selected based on the blank quality report.

Finally, after cutting, the finished product is quality inspected, and a finished product quality report is generated. This step involves detailed inspection of the finished product after cutting, resulting in a finished product quality report that reflects the type and location of defects in the finished mobile phone mid-frame. Finally, when the number of times the same defect appears in multiple finished product quality reports exceeds the first threshold, adjustments are made to the cutting or die-casting stage based on the finished product quality reports.

In this method, a perfectly symmetrical blank is first die-cast in the die-casting stage. Then, the overall quality of the blank determines the cutting direction. Finally, the quality of the finished product determines how to adjust the cutting or die-casting stage. This method balances the high material utilization of the die-casting + CNC machining method with the high precision of the full CNC machining method, reducing the focus on die-casting quality. Therefore, it can solve the problem of low yield rates in existing phone frame processing methods.

[0020] The high-strength lightweight mobile phone mid-frame processing method provided in this application embodiment can be applied to a high-strength lightweight mobile phone mid-frame processing equipment. In this case, the high-strength lightweight mobile phone mid-frame processing equipment is the executing entity of the high-strength lightweight mobile phone mid-frame processing method provided in this application embodiment. This application embodiment does not impose any restrictions on the specific type of high-strength lightweight mobile phone mid-frame processing equipment.

[0021] For example, high-strength lightweight mobile phone frame processing equipment may include a die-casting device, a cutting device, a quality inspection device, and a control device. The die-casting device may be a die-casting machine that performs die casting through a mold. The cutting device may be a CNC machine tool used to cut the rough blank to be processed. The quality inspection device may be a machine vision device or an X-ray scanning device used to inspect the rough blank and the finished product. The control device is communicatively connected to the die-casting device, the cutting device, and the quality inspection device. The control device can control the die-casting device to perform die casting, control the cutting device to perform cutting according to different cutting paths, and control the quality inspection device to inspect the rough blank and the finished product.

[0022] The control device can be a microcontroller, microprocessor, mobile phone, tablet computer, laptop computer, netbook, desktop computer, computer, laptop computer, etc.

[0023] To better understand the high-strength lightweight mobile phone mid-frame processing method provided in this application embodiment, the specific implementation process of the high-strength lightweight mobile phone mid-frame processing method provided in this application embodiment will be described by way of example below.

[0024] Figure 1 This paper illustrates a schematic flowchart of a high-strength, lightweight mobile phone mid-frame processing method provided in an embodiment of this application. The high-strength, lightweight mobile phone mid-frame processing method is applied to the debugging stage of mobile phone mid-frame processing and consists of two stages: die casting and cutting. After cutting, the rough blank is then precision-machined as needed. The method includes: S100 refers to a completely symmetrical blank to be processed obtained during the die casting stage. A completely symmetrical blank means that the front and back sides of the blank are completely symmetrical, and the upper and lower parts of the same side are also completely symmetrical.

[0025] It is understandable that existing full CNC machining methods involve cutting on a single rectangular substrate, while existing die-casting + CNC machining methods involve finishing the blank after die-casting. Because the substrate in the full CNC machining method is a single rectangular block, it can cut the front of the phone onto either the front or back of the rectangular block, and the front or back can be upside down. Therefore, the full CNC machining method can select four cutting directions. In this method, a completely symmetrical blank is obtained through a die-casting device. Complete symmetry means that the front and back of the blank are completely symmetrical, and the upper and lower parts of the same side are also completely symmetrical. It does not have to be a single rectangular substrate. That is, a completely symmetrical blank has four cutting directions. Therefore, for a completely symmetrical blank, any cutting direction can be selected for cutting.

[0026] This setup can take into account the characteristics of both full CNC machining and die casting + CNC machining methods, which is conducive to improving material utilization while increasing the quality of finished products.

[0027] In one possible implementation, in S100, a perfectly symmetrical rough blank is obtained during the die-casting stage, including: S110, determine the first model based on the design model; where the first model refers to the coincident model of the design models in the four cutting directions.

[0028] It's understandable that the finished phone frame won't be perfectly symmetrical. To maximize material utilization, the design model of the phone frame can be divided into four parts, each corresponding to a different cutting direction. These four parts are then overlapped to form a new first model. A certain allowance is added to this first model (to prevent material shortages in die-cast parts from affecting the finished product quality). Specifically, the first model is obtained by rotating the design model 180° around its length axis, 180° around its width axis, and simultaneously around both its length and width axes, performing a Boolean operation on the design model itself, finding the union, and then offsetting it outwards by a preset machining allowance (0.3mm-0.5mm). This allows for the cutting of the finished phone frame in any cutting direction.

[0029] S120, design the mold according to the first model and die-cast it to obtain the rough blank to be processed.

[0030] It is understandable that the mold is designed and manufactured according to the first model, and then the blank to be processed is obtained by die casting through the mold and die casting device. At this time, the blank to be processed can be cut into the finished mobile phone frame in any cutting direction.

[0031] With this setup, the first model can adaptively select any cutting direction for cutting while maintaining high material utilization, which is beneficial for improving the quality of the finished product.

[0032] S200 involves quality inspection of the rough blank to be machined, resulting in a rough blank quality report. This report includes quality scores for various local areas.

[0033] It is understandable that the quality inspection method can be a simple and fast machine vision + AI. The machine vision is used to observe the surface of the blank to be processed, and then the AI ​​is used to determine whether there are defects on the surface of the blank, as well as the type, size and location of the surface defects. As for how to identify surface defects of die castings through machine vision + AI, this is existing technology and will not be elaborated here.

[0034] After determining the type, size, and location of surface defects on the rough blank to be processed, the quality score of a region can be determined based on the type of defect or the proportion of defect area within that region. The region to be scored can be divided into fixed-size mesh cells, each assigned coordinates (x, y), and the mesh cells with defects can be marked. Then, the quality score S = This is a method for determining quality scores based on the proportion of defect area. Individual weights can also be assigned to each defect type, as the weight of porosity defects is significantly less than that of cracks. For example, crack weight is w1; large-area shrinkage cavities weight is w2; and dispersed porosity weight is w3. Therefore, the quality score S = The defect area is calculated as the area of ​​a single mesh cell multiplied by the number of mesh cells of that defect type. This method determines the quality score based on the proportion of defect area and the weight of defect type. The method is more complex but the results are more accurate.

[0035] Optionally, the process of obtaining the first quality score includes: S210 divides the area to be evaluated into grid cells of fixed size, and then marks the grid cells with defects according to the rough blank quality report.

[0036] It is understandable that the area to be evaluated is divided into grid cells of fixed size, each cell is assigned coordinates (x, y), and then the grid cells with defects are marked.

[0037] S220: Based on the number of marked mesh cells and the type of defects in the region to be evaluated, the first quality score of the region to be evaluated is obtained.

[0038] It's understandable to assign a separate weight to each defect type, because the weight of porosity defects is significantly less than that of crack defects. For example, the weight of cracks is w1, the weight of large-area shrinkage cavities is w2, and the weight of dispersed porosity is w3 (w1>w2>w3); therefore, the S quality score = The defect area is calculated as the area of ​​a single mesh cell multiplied by the number of mesh cells for that defect type. If the quality inspection device is an X-ray or CT scanner, the resulting rough blank quality report will be three-dimensional, in which case the defect area will be converted to defect volume, and the mesh cells will also be cells with a fixed volume.

[0039] This setup allows for the determination of the first quality score for any area on the rough blank to be processed, based on the rough blank quality report.

[0040] S300: Select the cutting direction of the blank to be machined based on the blank quality report.

[0041] It is understandable that the blank to be processed is symmetrical about two axes (i.e., like a cuboid, its shape remains unchanged after being flipped left and right and up and down). Therefore, there are four cutting directions for the blank to be processed during the cutting process. Under the four cutting directions, different parts of the blank to be processed will be cut off according to the cutting template. Therefore, it is necessary to select the cutting direction of the blank to be processed based on the blank quality report so that the parts cut off are the parts with poor quality. Specifically, the mass fraction of each local part on the blank to be processed can be quantified, and the cutting can be simulated in four directions. Then, the mass fraction of the remaining part after cutting can be determined, and the cutting direction with the highest mass fraction of the remaining part can be selected as the final cutting direction.

[0042] In one possible implementation, in S300, the cutting direction of the blank to be machined is selected based on the blank quality report, including: S310 simulates cutting the blank in four cutting directions and calculates the first quality score of the cut part based on the blank quality report.

[0043] It is understandable that the four cutting directions are front and forward, front and reverse, reverse and forward, and reverse and reverse (front means the screen is facing the cutting device, forward means the workpiece is not upside down, i.e. the charging hole is facing down). Simulated cutting is performed according to these four cutting directions, and different parts are cut off from the workpiece. The sum of the local quality scores of the cut parts is determined according to the workpiece quality report, which is the first quality score.

[0044] S320, select the cutting direction with the lowest first quality score as the cutting direction of the workpiece to be machined.

[0045] It is understandable that four first quality scores are obtained based on the four cutting directions. The lower the first quality score, the worse the quality of the cut-off part, and the better the quality of the retained part. Therefore, the cutting direction with the lowest first quality score is selected as the cutting direction of the blank to be processed, so that the quality of the finished product after cutting is also better.

[0046] This setting can automatically select the cutting direction of the worst-cut part, so that the quality of the retained part is better, and the quality of the finished product after cutting can be improved.

[0047] S400 determines the cutting path based on the cutting direction and performs the cutting.

[0048] It is understandable that after selecting the cutting direction, the design model of the mobile phone frame corresponding to the cutting direction is substituted into the model. After designing the cutting path, the CNC machine tool performs cutting according to the cutting path.

[0049] After the S500 machining process is completed, the finished product undergoes quality inspection, and a finished product quality report is generated. This report reflects the type and location of defects in the finished product.

[0050] It is understandable that after the cutting is completed, a finished product with a basic shape is obtained. The finished product is then inspected to generate a finished product quality report. The finished product quality report is used to reflect the type and location of defects in the finished product. Sampling inspection methods can include visual inspection, acoustic emission detection, etc., in order to determine the type and location of defects. Defect types can include porosity, shrinkage cavities / shrinkage porosity, patterns, cracks, deformation, flash, etc. The finished product can be divided into different local blocks, and the location can be the number of the local block.

[0051] S600: When the number of times the same defect appears in multiple finished product quality reports exceeds the first threshold, adjustments are made to the cutting stage or die-casting stage based on the finished product quality reports.

[0052] It is understandable that after inspecting multiple finished products, multiple finished product quality reports are obtained. Defects of the same type within the same local area are regarded as the same defect. When the number of times the same defect appears in multiple finished product quality reports exceeds the first threshold, it means that there is a process problem in the die casting process that causes the die casting to have regular repetitive defects. Therefore, the cutting stage or die casting stage is adjusted according to the finished product quality report to eliminate the regular repetitive defects in the die casting.

[0053] This setup first improves the quality of the die-casting process through closed-loop adjustment, then determines the local and overall quality of the die-cast parts based on the die-casting data of the entire process, and selects an optimal cutting direction. After cutting, the quality of the cut products is randomly inspected. When regular recurring defects appear, the corresponding die-casting stage is adjusted to eliminate or reduce these recurring defects. This can solve the problem of low yield of mobile phone mid-frames produced by existing mobile phone mid-frame processing methods.

[0054] In one possible implementation, in S600, when the number of times the same defect appears in multiple finished product quality reports exceeds a first threshold, adjustments are made to the cutting stage or die-casting stage based on the finished product quality reports, including: S610: If the same defect in the blank to be processed occurs in any or more cutting directions, then select the cutting direction with the lowest first quality score as the cutting direction of the blank to be processed; otherwise, output an optimized die casting command.

[0055] It is understandable that when a regularly repeating defect appears in the cut portion in any cutting direction, the regularly repeating defect can be removed by cutting in that cutting direction. If the regularly repeating defect appears in the cut portions in multiple cutting directions, the cutting direction with the lowest first quality score can be selected as the cutting direction for the rough blank to be processed according to steps S310-S320, so that the quality score of the remaining part is the highest. If the regularly repeating defect does not appear in the cut portion in any cutting direction and cannot be removed, an optimized die-casting instruction is output. The optimized die-casting instruction is used to instruct the operator to replace or repair the mold or change at least one parameter of the mold temperature, injection speed, or holding time in the die-casting stage. The optimized die-casting instruction includes the location information of the repeating defect in the mold.

[0056] This setup provides a certain degree of adaptive adjustment capability for recurring defects caused by mold problems, and automatically sends optimization die-casting commands when the problem exceeds the adjustment capability range, allowing operators to replace or repair the mold.

[0057] Optionally, the method also includes: S710: When n consecutive finished product quality reports indicate that the finished product is defect-free, the debugging phase of the mobile phone mid-frame processing ends.

[0058] It is understandable that when multiple consecutive finished product quality reports indicate that the finished product is defect-free, it means that the debugging is successful and the production line can stably produce qualified finished products. Therefore, when n consecutive finished product quality reports indicate that the finished product is defect-free, the debugging stage of the mobile phone frame processing ends, where n can be an integer greater than 2.

[0059] This setting clearly defines when the debugging phase should automatically end, thus improving the level of automation.

[0060] Optional methods include machine vision and AI judgment, X-ray scanning, and other methods. S720: When the quality inspection method is machine vision and AI judgment, the area to be evaluated is divided into regions according to area; when the quality inspection method is X-ray scanning, the area to be evaluated is divided into regions according to volume.

[0061] It is understandable that if the quality inspection method for the blank to be processed is machine vision and AI judgment, only the area of ​​surface defects of the blank to be processed can be determined. Therefore, in the process of obtaining the first quality score, the area to be scored is divided into regions according to the area. If the quality inspection method for the blank to be processed is X-ray scanning, the volume of internal defects of the blank to be processed can be determined. Therefore, in the process of obtaining the first quality score, the area to be scored is divided into regions according to the volume.

[0062] This setup takes into account the different processes of obtaining the first quality score under the two quality inspection methods.

[0063] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0064] This application embodiment also provides a high-strength, lightweight mobile phone mid-frame processing equipment. The equipment is applied to the debugging stage of mobile phone mid-frame processing and is divided into two stages: die casting and cutting. The equipment includes: A die-casting apparatus for obtaining a completely symmetrical blank to be processed during the die-casting stage; wherein, the completely symmetrical blank to be processed means that the front and back sides of the blank to be processed are completely symmetrical, and the upper and lower parts of the same side are also completely symmetrical. A quality inspection device is used to inspect the rough blank to be processed and obtain a rough blank quality report; wherein, the rough blank quality report includes quality scores for each local area; A control device for selecting the cutting direction of the rough blank to be processed based on the rough blank quality report; A cutting device is used to determine the cutting path according to the cutting direction and to perform cutting; The quality inspection device is also used to inspect the finished product after cutting and generate a finished product quality report; wherein the finished product quality report is used to reflect the type and location of defects in the finished product; The control device is also used to adjust the cutting stage or the die-casting stage according to the finished product quality reports when the number of times the same defect appears in multiple finished product quality reports is greater than a first threshold.
