Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
The embodiment of the invention provides a shell machining method which is used for machining a shell. The shell machining method comprises the following steps:
1: providing a first shell base body, wherein the first shell base body is provided with a cavity, a first parting surface and a first matching surface, the first parting surface is positioned at the opening end of the cavity, the first matching surface is positioned outside the cavity, and the first parting surface and the first matching surface have a break;
2: providing a mold having a second parting surface for mating with the first parting surface;
3: matching the mold with the first shell body to enable the first parting surface to be attached to the second parting surface;
4: injecting an insulating material into the cavity to obtain a second shell base body;
5: providing a clamp having a second mating surface for mating with the first mating surface;
6: matching the clamp with the second shell substrate to enable the first matching surface to be attached to the second matching surface;
7: and processing the second shell base body.
Specifically, the first casing base in step 1 may be a blank, which may be a metal plate or a non-metal plate. The first housing base body can be manufactured by various processes, for example, when the first housing base body is made of a metal material, the first housing base body can be manufactured by cutting, extruding, roughly milling an inner cavity and the like of a section bar.
In the first embodiment, as shown in fig. 1 and 2, the first housing base 10 has a cavity 11, the cavity 11 has an opening (not shown), and the cavity 11 is a molding cavity of the insulating material layer. The first housing base 10 further has a first parting surface 111 located at the opening end of the cavity 11 (i.e. the end close to the opening), and a first mating surface 12 located outside the cavity 11, and the first parting surface 111 is offset from the first mating surface 12. Wherein the first parting surface 111 is a surface that mates with a second parting surface of a mold, which is brought into contact with or separated from the first housing base 10 at the first parting surface 111. The first mating surface 12 is a surface that mates with the second mating surface of the fixture. The first mating surface 12 is located outside the cavity 11, so that no overflow of the insulating material layer is formed on the first mating surface 12. There may be a small amount of flash on the first parting surface 111.
As shown in fig. 2, in the first embodiment, the distance from the first parting surface 111 to the bottom wall 112 of the cavity 11 is smaller than the distance from the first mating surface 12 to the bottom wall 112 of the cavity 11. For example, in the view of fig. 2, the first parting surface 111 is lower than the first mating surface 12. The first housing base body 10 may further have a connecting side surface 121, the connecting side surface 121 is connected between the first parting surface 111 and the first mating surface 12, and the connecting side surface 121 is located outside the cavity 11. I.e. the first parting surface 111 and the first mating surface 12 are connected by the connecting side 121 to form a step. It should be noted that in the first embodiment, the structural features such as the shape, configuration, position, etc. of the cavity 11, the first parting surface 111, and the first mating surface 12 can be set according to actual needs while satisfying the above description, and are not limited to those shown in fig. 1 and 2.
Alternatively, in the second embodiment, as shown in fig. 3 and 4, the first housing base 20 has a cavity 21, the cavity 21 has an opening (not shown), and the cavity 21 is a molding cavity for the insulating material layer, as in the first embodiment. The first housing base 20 further has a first parting surface 211 located at the opening end (i.e. the end close to the opening) of the cavity 21, and a first mating surface 22 located outside the cavity 21, and the first parting surface 211 is offset from the first mating surface 22. Unlike the first embodiment, the distance from the first parting surface 211 to the bottom wall 212 of the cavity 21 is larger than the distance from the first mating surface 22 to the bottom wall 212 of the cavity 21. For example, in the view of fig. 4, the first parting surface 211 is higher than the first mating surface 22. I.e. the first parting surface 211 is spaced further from the first mating surface 22 than by connecting the side surfaces to form a step. It should be noted that in the present second embodiment, the structural features of the shape, configuration, position, etc. of the cavity 21, the first parting surface 211 and the first mating surface 22 may be set according to actual needs on the premise of satisfying the above description, and are not limited to those shown in fig. 3 and 4.
In other embodiments, the first housing base body may have the connecting side surface, and a distance between the first parting surface and the bottom wall of the cavity is larger than a distance between the first mating surface and the bottom wall of the cavity; or the first shell base body is not provided with the connecting side face, the first parting face is far away from the first matching face, and the distance from the first parting face to the bottom wall of the cavity is smaller than the distance from the first matching face to the bottom wall of the cavity.
Further, in this embodiment, between step 1 and step 2, the shell processing method may further include performing a finishing process on the first parting surface (e.g., the first parting surface 111). The finishing refers to a processing method such as super finishing, polishing, lapping, honing, etc., which does not cut or cuts off an extremely thin material layer from a workpiece to reduce the surface roughness of the workpiece. Through the finishing process, the surface quality of the first parting surface is higher, and the fit clearance between the first parting surface and the second parting surface is smaller, so that the insulating material can be prevented from overflowing onto the first parting surface, and further, the first fit surface (such as the first fit surface 12) is prevented from overflowing.
Specifically, as shown in fig. 5, the mold 30 in step 2 has a second parting surface 33, and the second parting surface 33 is used for matching with the first parting surface (e.g., the first parting surface 111). The mold 30 is used for injection molding. It should be understood that the detailed configuration of the mold 30 may be arranged as desired, and that the illustration in FIG. 5 is merely exemplary.
Further, in this embodiment, between step 2 and step 3, the method for processing the housing may further include: and performing the finishing processing on the second section surface. Through finishing, the surface quality of the second parting surface is higher, and the fit clearance between the second parting surface and the first parting surface is smaller, so that the insulating material can be prevented from overflowing onto the first parting surface, and further, the first fitting surface (such as the first fitting surface 12) is prevented from being overflowed.
Further, in this embodiment, between step 1 and step 2, or between step 2 and step 3, the method for processing a housing may further include: and roughening the inner surface of the cavity to form a nano-scale pit on the inner surface of the cavity. The roughening treatment may include, for example, the following steps: the first housing base (for example, the first housing base 10) is soaked in the alkaline solution to clean the grease on the surface of the first housing base 10. The alkali liquor can be weak alkali solution with the pH value of 9-10, and the soaking time can be 1 minute; soaking the first shell substrate 10 in acid liquor to neutralize the pH value of the surface of the first shell substrate 10; the first housing base 10 is immersed in the T-bath to form a nano-scale pit in the inner surface of the cavity 11. The solution T may contain various chemicals, wherein the L-alanine is the main component of the solution T. After the soaking in the T liquid, the diameter of a pit formed on the inner surface of the cavity 11 is 20-30 nm, and the pit is in a coral reef structure; putting the first shell matrix 10 into water for washing to remove residual chemical solution; the first housing base 10 is dried for further use. Further, the above roughening process may be repeated a plurality of times to form nano-scale pits in the inner surface of the cavity 11, depending on the type of material and the corrosion resistance of the material of the first housing base 10. The bonding strength of the insulating material to the inner surface of the cavity 11 is greatly increased in step 4 due to the formation of nano-scale pits.
Further, in this embodiment, the roughening treatment of the inner surface of the cavity may include: the first mating surface (such as the first mating surface 12) is sealed, and the inner surface of the cavity is roughened. This serves to shield the first mating surface 12 from the first mating surface 12 also forming nano-scale pits. Therefore, the first matching surface 12 can be tightly matched with the second matching surface, and stable clamping of the clamp is facilitated. For example, a protective layer may be applied to the first mating surface 12 to provide a hermetic seal, or the first mating surface 12 may be sealed within a housing, etc.
Specifically, as shown in fig. 5, in step 3, the mold 30 is engaged with the first casing base (e.g., the first casing base 10) to make the second parting surface 33 fit with the first parting surface (e.g., the first parting surface 111). Of course, other parting surfaces on the mold 30 can also be attached to other surfaces of the first housing base 10 to close the cavity 11 for subsequent injection molding according to the specific requirements of injection molding.
Further, as shown in fig. 5, the connecting side 121 may have a draft angle (not shown), that is, the connecting side 121 has a slope. The draft angle may be set according to specific needs, and may be, for example, 0.5 ° to 2 °. The mold 30 has a third mating surface 31. In step 3, the third mating surface 31 and the connecting side surface 121 may be simultaneously attached to reliably mount the first housing base 10 on the mold 30. The purpose of this kind of setting is: after the injection molding process of step 4 is completed, the mold 30 is opened to separate the mold 30 from the first housing base 10 (i.e., open mold, which will be described in detail below). The connecting side 121 is designed to be a surface with a slope, so that the resistance of opening the mold can be reduced. In addition, under the pressure of the mold clamping (i.e., the mold 30 is matched with the first housing base 10 to close the cavity 11), the matching surface of the mold 30 is pressed more tightly on the connection side surface 121 with the slope, so that the connection side surface 121 and thus the first matching surface 12 can be prevented from being burdened.
Further, as shown in fig. 5, a flash tank 122 may be formed on the connecting side 121. The flash tank 122 is used to contain insulating material that may overflow from the cavity 11. Due to the provision of the flash tank 122, any flash of insulating material that may escape will enter the flash tank 122 and will not reach the first mating surface 12. The flash tank 122 may extend across the connecting side 121 and be designed to be able to block the flash.
As shown in fig. 5, a first positioning portion 113 is provided on the first parting surface (e.g., the first parting surface 111), and a second positioning portion 32 is provided on the second parting surface 33. In step 3, the first positioning portion 113 and the second positioning portion 32 may be engaged to position the mold 30 on the first casing base (e.g., the first casing base 10) while the first parting surface 111 and the second parting surface 33 are being fitted. This enables the mold 30 and the first housing base 10 to be accurately and reliably fitted without being misaligned, so that flash due to misalignment can be avoided. The first positioning portion 113 may be a positioning groove or a positioning post, for example. Correspondingly, the second positioning portion 32 may be a positioning column or a positioning groove, for example. Alternatively, the first positioning portion 113 and the second positioning portion 32 may be other structures or components as long as they can cooperate to position the mold 30.
Specifically, as shown in fig. 6, in step 4, the second housing base (the portion other than the jig 40 in fig. 6) is obtained after injecting the insulating material into the cavity 11. An insulating material layer 114 may be formed in the cavity 11 of the second housing base. The insulating material layer 114 includes, but is not limited to, mounting portions for connecting other components as in the finished housing. The insulating material includes, but is not limited to, engineering plastics such as PC (polycarbonate), AB (acrylonitrile butadiene styrene), and the like.
In this embodiment, the injection molding process in step 4 may be performed on a table of an injection molding machine, and the specific injection molding process may include mold closing (i.e., placing the first housing base 10 into an injection chamber of the injection molding machine, and attaching the mold 30 to the first housing base 10 to close the cavity 11), glue injection (i.e., injecting an insulating material into the cavity 11), pressure maintaining (i.e., feeding a material to the cavity 11 under a certain injection pressure when the injection process is nearly completed, so as to fill a volume vacated by shrinkage of a product), cooling, mold opening (i.e., separating the first housing base 10 from the mold 30, so as to open the closed cavity 11), and product taking out (i.e., demolding). After the workpiece is taken out, burrs on the surface of the workpiece can be removed, and polishing, cleaning and the like are carried out, so that the second shell base body is finally obtained.
Further, in this embodiment, step 4 may include: and injecting an insulating material into the cavity 11, so that the insulating material is infiltrated into the concave pit and tightly combined with the inner surface of the cavity 11 to obtain the second shell base body. The injection step can be performed by, for example, nano injection molding, whereby a complicated insulating material layer 114 can be formed, the degree of freedom in designing a thin-walled case can be improved, and a case having a lighter weight and a higher structural strength can be manufactured.
In the prior art, the insulating material layer formed may overflow on the first parting surface of the workpiece due to poor product design or manufacturing errors. If the first parting surface is used as a first matching surface matched with the clamp, the clamp can be jacked up by flash, so that the clamp cannot clamp a workpiece stably, and subsequent processing is influenced.
In the embodiment, as shown in fig. 6, after the first parting surface 111 is attached to the mold 30, the insulating material may overflow from the cavity 11 onto the first parting surface 111 due to a processing error of the mold 30 or an abnormal process parameter of the injection molding, but the overflow area of the insulating material is usually very small, and the thickness of the overflowing insulating material layer is also very small. Since the first mating surface 12 is located outside the cavity 11, the first mating surface 12 and the first parting surface 111 have a step, and the step is larger than the thickness of the flash (for example, the step is designed to be larger than the thickness tolerance of the overflowing insulating material layer), the method for processing the housing can ensure that the flash possibly on the first parting surface 111 does not reach the first mating surface 12, and no flash exists on the first mating surface 12. Thus, the clip can be smoothly clamped on the first mating surface 12.
Further, in this embodiment, between step 4 and step 6, for example, between step 4 and step 5 or between step 5 and step 6, the housing processing method may further include: and cleaning the first matching surface. The purpose of this process is: the injection molding process of step 4 may form flash or other contamination on the first mating surface; steps 1-3 may also introduce contamination on the first mating surface. Therefore, after the first matching surface needs to be cleaned, the second matching surface of the clamp in the step 6 is tightly attached to the first matching surface, and the clamp can be stably clamped. Of course, the first matching surface can be also subjected to finishing treatment.
Specifically, as shown in fig. 6, in fig. 5 and 6, the first mating surface 12 of the second housing base (i.e., the first mating surface 12 of the first housing base 10) is attached to the second mating surface 41 of the fixture 40, so that the second housing base is clamped on the fixture 40 for subsequent processing. It should be understood that the detailed configuration of the clamp 40 can be arranged as desired, and that the illustration in FIG. 6 is merely exemplary.
Further, in this embodiment, step 6 may include the following steps:
61: mounting the clamp on a machining machine table;
62: and fixing the second shell substrate on the clamp on the processing machine table, so that the first matching surface is attached to the second matching surface.
Or, the second housing base may be clamped to the fixture 40, and then the second housing base and the fixture may be mounted on the processing machine.
Further, in this embodiment, step 6 may further include step 63: the position of the second housing base mounted to the jig 40 is detected. The process is used for detecting whether clamping of the second shell base body is in place. Correcting the position of the second shell base body when the second shell base body is not clamped in place; and carrying out the next procedure when the clamping is in place.
Further, in this embodiment, as shown in fig. 7, the first mating surface 12 may be provided with a connection hole 123. The connection hole 123 may be a positioning hole in the machining process; or as mounting holes in the finished housing for mounting other components to the housing.
Further, in the present embodiment, as shown in fig. 7, the jig 40 may have a connection portion 42. In step 6, the connecting portion 42 is inserted into the connecting hole 123, so that the second mating surface 41 is attached to the first mating surface 12. That is, the connecting hole 123 can be used as a positioning hole during the machining process, and the fixture 40 clamps and positions the second housing base body through the matching of the connecting portion 42 and the connecting hole 123.
Specifically, as shown in fig. 7 and 8, the second housing base has a processing surface 13 located outside the cavity 11 and facing away from the jig 40. Wherein, further, step 7 may comprise: an antenna slot 131 is formed in the processing surface 13, and the antenna slot 131 penetrates the cavity 11. The antenna slot 131 may be right through to the insulating-material layer 114 in the cavity 11 without extending into the insulating-material layer 114, or the antenna slot 131 may cut away part or all of the insulating-material layer 114. The antenna slot 131 is used for passing out the antenna rf signal. In this embodiment, the shape and size of the antenna slot 131 can be set as required.
In this embodiment, since the first mating surface 12 of the second housing base does not have the insulating material overflowing, the clamp 40 can be stably clamped on the first mating surface 12, and then the second housing base can be reliably processed. From this, the machining precision of product can be guaranteed to the scheme of this embodiment, promotes the shaping quality of casing.
Further, in this embodiment, step 7 may further include: the antenna slot 131 is filled with a non-signal shielding material. The filled non-signal shielding material can enhance the structural strength of the product, ensure the integrity of the appearance of the product and not influence the radio frequency signal of the antenna.
As shown in fig. 9, the embodiment of the present invention further provides a housing 50, and the housing 50 is processed by the above-mentioned housing processing method. For example, the housing 50 may have an antenna slot 51 formed therein. The housing 50 may be a housing of any product, for example, a housing of a terminal device such as a mobile phone, a tablet computer, and a notebook computer. The housing 50 of the present embodiment has high molding quality.
As shown in fig. 10, an embodiment of the present invention further provides a terminal device 60, which includes the housing 50 and the display screen 61. The housing 50 has an opening (not shown). The display screen 61 is accommodated in the housing 50 and can be exposed from the opening of the housing 50 for the user to view or operate. The terminal device 60 includes, but is not limited to, an electronic terminal such as a mobile phone, a tablet computer, a notebook computer, etc., and may be a mobile phone, for example. Wherein the housing 50 may be, for example, a back case of a cell phone.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
