Referring to fig. 1, fig. 1 is a mobile terminal 100 according to an embodiment of the present disclosure, where the mobile terminal 100 may be any device with communication and storage functions, for example: the system comprises intelligent equipment with a network function, such as a tablet computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a notebook computer, vehicle-mounted equipment, a network television, wearable equipment and the like.
Referring to fig. 1, the mobile terminal 100 includes a housing 110, and the housing 110 is used for encapsulating a functional device 130. The functional device 130 includes an antenna. The housing 110 is made of metal, and the metal housing 110 shields electromagnetic waves radiated by the antenna, so that the built-in antenna of the mobile terminal 100 cannot receive and transmit electrical signals. In order to solve the problem of shielding the metal case 110 of the mobile terminal 100 from electromagnetic waves, the antenna micro-gap 120 is processed on the metal case 110, and then the antenna micro-gap 120 is filled with an insulating medium to seal the metal case 110, so that the built-in antenna of the mobile terminal 100 radiates signals through the antenna micro-gap 120. However, in the process of forming the antenna micro-gap 120, the filling medium is not well combined with the inner wall of the antenna micro-gap 120, which may cause problems such as poor sealing or generation of bubbles, thereby affecting the overall strength and waterproof performance of the housing 110.
Referring to fig. 2, fig. 2 is a diagram illustrating a housing 110 according to an embodiment of the present disclosure, which can be used as a battery back case of the mobile terminal 100. The housing 110 includes a housing base 111, a base 112 stacked on the housing base 111, an antenna micro-gap 120 penetrating the housing base 111 and extending to the base 112, and a sealing layer 113 filled in the antenna micro-gap 120. The substrate 112 has a top wall 1121 that conforms to the sealing layer 113. The top wall 1121 has a cross section that is convex in the middle and concave in both sides.
In this embodiment, the sealing layer 113 is formed by filling a sealing glue into the antenna micro-gap 120 and curing the sealing glue.
In this embodiment, referring to fig. 3, the housing base 111 is made of metal, and the substrate 112 is made of injection molded plastic. Due to the unstable combination of plastic and metal, there is a high possibility that a gap 114 exists between the housing base 111 and the substrate 112. After the sealing glue is filled in the antenna micro-gap 120, the filling of the sealing glue is stopped, and the sealing glue is cured, and after the filling of the sealing glue is stopped, the sealing glue may enter the gap 114 between the housing base 111 and the substrate 112, so that defects such as bubbles are formed in the sealing layer 113.
By processing the antenna micro-seam 120 on the substrate 112 and the shell body 111 which are arranged in a stacked manner, and enabling the cross section of the substrate 112 at the bottom of the antenna micro-seam 120 to be in a shape of a convex middle part and concave two sides, after the antenna micro-seam 120 is filled with sealing glue, the sealing glue can be filled in a gap 114 between the antenna micro-seam 120 and the substrate 112 preferentially, so that the problem that the sealing quality of the sealing layer 113 is poor and the like due to the fact that the sealing glue enters the gap 114 after the antenna micro-seam 120 is filled with the sealing glue is solved, and the forming quality and the sealing quality of the sealing layer 113 are improved; in addition, the cross section of the substrate 112 is convex in the middle and concave in the two sides, and the contact area between the sealing layer 113 and the substrate 112 can be increased, so that the attaching strength between the sealing layer 113 and the substrate 112 is increased, the sealing quality of the shell 110 is improved, and the reliability of the mobile terminal 100 is improved.
In one possible embodiment, referring to fig. 4 and 5, the substrate 112 includes a first groove 1122 and a second groove 1123, and a protrusion 1124 formed between the first groove 1122 and the second groove 1123. The antenna micro-slot 120 includes a first side wall 1201 and a second side wall 1202 disposed opposite each other. The first groove 1122 is smoothly connected to the first sidewall 1201, and the second groove 1123 is smoothly connected to the second sidewall 1202. Since the first groove 1122 is smoothly connected to the first sidewall 1201 so that the gap 114 between the housing base 111 and the substrate 112 is exposed to the inner wall of the antenna micro-gap 120, the sealing glue can easily enter the gap 114 when the sealing glue is filled, thereby reducing the occurrence of defects such as air bubbles in the sealing layer 113 and improving the sealing quality of the housing 110.
Referring to fig. 6 to 7, fig. 6 is a method 10 for manufacturing a housing 110 according to an embodiment of the present disclosure. The manufacturing method of the shell comprises the following steps.
In this embodiment, referring to fig. 7, the shell substrate 111 is first cut from the shell 110, and then is subjected to multiple stamping by a die to form a shell 110 with a uniform thickness, and then the shell 110 is subjected to machining, milling, grinding, and cutting by a Computer Numerical Control (CNC) machine to form the shell substrate 111. The housing base 111 is substantially in the form of a rectangular plate. The housing base 111 has a first surface 1111 and a second surface 1112 disposed opposite to the first surface 1111. The first surface 1111 and the second surface 1112 may be flat surfaces or arc surfaces. Wherein the first surface 1111 faces the functional device 130 in the housing 110, and the second surface 1112 faces the external environment.
In this embodiment, a substrate 112 is molded on the first surface 1111 of the housing base 111. The base 112 and the housing base 111 are stacked. The substrate 112 is used to provide a supporting force when the antenna micro-slots 120 are cut on the housing base 111, so as to prevent the housing base 111 from bending and deforming.
In one embodiment, the substrate 112 is formed using an injection molding process. The molding process of the substrate 112 includes the following steps.
Step 1021, providing a mold. Referring to fig. 8, the mold includes an upper mold 151 and a lower mold 152. The upper mold 151 and the lower mold 152 correspond to the second surface 1112 and the first surface 1111, respectively.
Step 1022, placing the housing base 111 into the mold. The first surface 1111 of the housing base 111 is disposed on the lower mold 152, the second surface 1112 faces the upper mold 151, and a smaller gap 153 is reserved between the first surface 1111 and the lower mold 152.
Step 1023, a base 112 stock material is injected into the mold. The substrate 112 starting material is in a liquid state. The base 112 starting material is injected into the gap 153 between the first surface 1111 and the upper die 151.
In step 1024, please refer to fig. 9, the substrate 112 is formed. The upper mold 151 and the lower mold 152 are pressed against each other, the raw material of the substrate 112 is pressed to mold the substrate 112, and the substrate 112 is molded on the first surface 1111 of the housing base 111.
In this embodiment, the housing base 111 is made of metal and is used for preparing a rear battery cover of the mobile terminal 100. The metal case 110 shields electromagnetic waves, so that the built-in antenna of the mobile terminal 100 cannot receive and transmit electric signals. In order to solve the problem of shielding electromagnetic waves by the metal case 110 of the mobile terminal 100, the antenna micro-slot 120 is formed on the metal case 110, so that the built-in antenna of the mobile terminal 100 radiates signals through the antenna micro-slot 120.
In this embodiment, referring to fig. 10, the housing base 111 is horizontally (referring to the drawing) placed on a computer numerical control machine, and the CNC milling cutter 155 is used to cut the antenna micro-seam 120 on the housing base 111. The milling cutter cuts from the second surface 1112 toward the first surface 1111, and the milling cutter 155 cuts through the housing base 111 and then cuts into the substrate 112 to form the antenna micro-slot 120 extending through the housing base 111 and into the substrate 112 as the substrate 112 is attached to the first surface 1111. It should be understood that, in the present embodiment, the milling cutter 155 cuts the housing base 111 by penetrating from the first surface 1111 toward the second surface 1112, instead of cutting the housing base 111 into two separate pieces. When cutting the plurality of antenna micro-slots 120, the substrate 112 may be used to support the housing base 111, and the substrate 112 keeps the cutting process between the adjacent antenna micro-slots 120 from bending and deforming.
In this embodiment, after the antenna micro-gap 120 is formed, the bottom of the antenna micro-gap 120 corresponding to the substrate 112 may have a shape of a middle protrusion 1124 and two side recesses.
In a first embodiment, referring to fig. 11-13, in the process of processing the housing base 111 and the substrate 112, the antenna micro-gap 120 may be formed by multiple cutting, which includes the following steps.
In the second embodiment, in the process of processing the housing base 111 and the substrate 112, the antenna micro-gap 120 may be formed by one-time cutting, which specifically includes the following steps.
In step 1030, referring to fig. 14, a cutter is used to cut the housing base 111 and the substrate 112, and a first groove 1122 and a second groove 1123 and a protrusion 1124 between the first groove 1122 and the second groove 1123 are formed on the substrate 112.
In one embodiment, step 1030 includes the following steps.
Step 1031, providing a cutter 158, wherein the cutter 158 is a circular blade, and the section of the tool tip of the cutter 158 is in a shape of bulges at two sides and a concave middle part.
And 1032, vertically placing the cutter 158 and the shell base body 111, controlling the cutter 158 to rotate at a high speed and cutting the shell base body 111 and the substrate 112. The cutter 158 cuts the housing base 111 and then cuts into the substrate 112.
Step 1033, after the tip of the tool 158 cuts into the substrate 112, the tool 158 is controlled to stop cutting. Since the cross section of the cutting tip of the cutting tool 158 is convex at two sides and concave at the middle, the cutting tool 158 forms two grooves, i.e., a first groove 1122 and a second groove 1123, on the substrate 112.
In this embodiment, the cutting process of the antenna micro-gap 120 can be completed at one time by using the cutter 158 having the section of the cutter point with the protrusions 1124 at both sides and the recess in the middle, thereby simplifying the process and improving the manufacturing efficiency of the housing 110.
In one embodiment, after the step 103 of processing the housing body 111 and the substrate 112 to form the antenna micro-gap 120, the first groove 1122 is smoothly connected to the inner wall of one side of the initial micro-gap 121, and the second groove 1123 is smoothly connected to the inner wall of the other side of the initial micro-gap 121.

1042, curing the first sealing glue, and forming a first sealing layer 1131. The first sealing layer 1131 covers the substrate 112.
In this embodiment, after the antenna micro-gap 120 is filled with the sealing glue, the sealing glue may be preferentially filled in the gap 114 between the antenna micro-gap 120 and the substrate 112, so as to reduce the problem that the sealing quality of the sealing layer 113 is poor due to bubbles generated in the sealing layer 113 after the sealing glue is filled in the antenna micro-gap 120 and enters the gap 114, and the like, thereby improving the molding quality of the sealing layer 113, further improving the sealing quality of the housing 110, and improving the reliability of the mobile terminal 100.
