Referring to FIG. 1 , the front case assembly 10 according to the embodiment of the present invention can be applied to an electronic device 100 . The electronic device 100 includes a body 20 on which the front case assembly 10 is disposed. The electronic device 100 includes but is not limited to a mobile phone, a tablet computer or a wearable device.

Specifically, the electronic device 100 further includes battery covers (not shown in the figure), and the battery covers are respectively located on the side of the casing 12 opposite to the panel assembly 14 .

Referring to FIGS. 2 to 5 , the front shell assembly 10 according to the embodiment of the present invention includes a shell 12 , a panel assembly 14 , at least one anti-spill strip 16 and a sealing strip 18 .

The casing 12 includes a bottom wall 124 and a side wall 126 extending from a side of the bottom wall 124 . The bottom wall 124 and the side wall 126 define a groove 122 . The panel assembly 14 includes a display screen 144 and a cover 146 . The display screen 144 includes a display area 1443 and a non-display area 1444 surrounding the display area 1443 , the cover plate 146 covers the display area 1443 and is at least partially indented relative to the edge of the display screen 144 . In other words, the size of the cover plate 146 is smaller than that of the display screen 144 .

The anti-overflow strip 16 is formed by disposing anti-overflow glue on the inner side of the side wall 126 along the circumferential direction of the side wall 126 and curing it. The panel assembly 14 is disposed in the groove 122 . The anti-spill strip 16 seals the gap 11 between the side wall 126 and the edge 142 of the panel assembly 14 . The caulking strip 18 is formed by disposing and curing caulking glue in the gap 11 between the top 1262 of the sidewall 126 and the edge 142 of the panel assembly 14 . The sealing strip 18 is fixedly connected to the housing 12 and the panel assembly 14 .

In the front case assembly 10 according to the embodiment of the present invention, the front case assembly 10 forms at least one anti-overflow strip 16 by setting and curing the anti-overflow glue in advance, so that the anti-overflow strip 16 seals between the top 1262 of the side wall 126 and the edge 142 The gap 11 can prevent the caulking glue from penetrating into the groove 122 and contaminating the casing 12 and/or the panel assembly 14 when the caulking glue of the casing 12 and the panel assembly 14 is subsequently set. In addition, the cover plate 146 is at least partially indented relative to the edge of the display screen 144 , which can increase the area ratio of the display area 1443 to the cover plate 146 and increase the screen ratio of the electronic device 100 .

The casing 12 is roughly rectangular in shape, and the casing 12 is a carrier of the electronic device 100 for carrying most parts of the electronic device 100 . The housing 12 can be made of plastic or metal, or plastic and metal can be used to form an integrated structure through in-mold injection molding. In one example, the material of the bottom wall 124 is metal, and the material of the side wall 126 is plastic. The bottom wall 124 can be put into a mold first, and then molten plastic is injected into the mold to form the side wall 126 after the plastic solidifies. , so that the shell 12 is obtained.

In some embodiments, the side wall 126 includes an inner side 1222 , the bottom wall 124 includes a bottom surface 1228 connected to the inner side 1222 , and the inner side 1222 is a plane perpendicular to the bottom surface 1228 .

In some embodiments, the sidewall 126 includes an inner surface 1222 , the bottom wall 124 includes a bottom surface 1228 connected to the inner surface 1222 , and the inner surface 1222 is an inclined surface extending upward and outward from the sides of the bottom surface 1228 .

The inner surface 1222 may be perpendicular to the bottom surface 1228 , or may extend upward and outward from the edge of the bottom surface 1228 , and the specific structure of the front shell assembly 10 may be selected according to requirements.

In certain embodiments, the edge 142 of the panel assembly 14 includes a cover edge 1462 and a display edge 1442 . The anti-overflow strip 16 seals the gap 11 between the side wall 126 and the edge 1442 of the display screen, and the caulking strip 18 is fixedly connected to the edge 1462 of the cover plate and the top 1262 of the side wall 126 .

In this way, the edge 1462 of the cover plate and the top 1262 of the side wall 126 are connected by the sealing strip 18 , so that the panel assembly 14 is fixedly connected to the casing 12 .

Specifically, the material of the cover plate 146 may be made of light-transmitting materials such as glass, ceramics, or sapphire. Since the cover 146 is an input part of the electronic device 100 , the cover 146 is often touched by bumps or scratches. For example, when a user puts the electronic device 100 into a pocket, the cover 146 may be scratched and damaged by a key in the user's pocket. Therefore, the material of the cover plate 146 can be a material with relatively high hardness, such as the above sapphire material. Alternatively, a hardened layer is formed on the surface of the cover plate 146 to improve the scratch resistance of the cover plate 146 .

Specifically, the display screen 144 is, for example, a liquid crystal display module (LCD Module, LCM). Of course, the display module may also be a flexible display module. The touch layer on the display screen 144 is used for receiving user's touch input to generate a signal for controlling the content displayed by the display module.

The display screen 144 and the cover plate 146 are bonded and fixed together by Optically Clear Adhesive (OCA), for example. The optical adhesive not only bonds and fixes the display screen 144 and the cover plate 146 , but also transmits the light emitted by the display screen 144 .

In one example, the panel assembly 14 can be formed through the following steps: first provide the display screen 144 and the cover plate 146, then apply optical glue on the display screen 144, and finally stick the cover plate 146 on the optical glue, so that the cover Plate 146 is fixed with display screen 144 .

In some embodiments, the inner side 1222 includes a long side wall 1224 and a short side wall 1226 connected to the long side wall 1224 , and the anti-overflow strip 16 is disposed on the long side wall 1224 along the length direction of the long side wall 1224 . In this way, the size of the long sidewall 1224 is relatively large, and the anti-overflow strip 16 is arranged on the long sidewall 1224 along the length direction of the long sidewall 1224 to help seal the gap 11 between the inner side 1222 and the edge 1226 .

Referring to FIG. 5 , in some embodiments, the top 1262 of the side wall 126 is formed with a protrusion 1263 protruding toward the cover plate 146 , and the caulking strip 18 is fixedly connected to the protrusion 1263 and the panel assembly 14.

In this way, the bump 1263 can reduce the size of the gap between the cover plate 146 and the side wall 126, making the electronic device 100 more beautiful. In addition, the bump 1263 can increase the thickness of the top of the side wall 126, thereby improving the thickness of the side wall 126. Anti-seismic performance, reducing the impact received by the cover plate 146.

In some embodiments, the width of the gap between the edge of the cover plate 146 and the protrusion 1263 is equal to the width of the gap between the display screen 144 and the side wall 126 . In this way, it is beneficial to improve the consistency of the electronic device 100 and make the electronic device 100 more reliable. Of course, in other implementations, the width of the gap between the edge of the cover plate 146 and the protrusion 1263 may be smaller or larger than the width of the gap between the display screen 144 and the side wall 126 .

In some embodiments, the edge of the cover plate 146 is located above the non-display area 1444 . In other words, the edge of the cover plate 146 is located between the edge of the display area 1443 and the outer edge of the non-display area 1444 . In this way, while increasing the screen ratio of the electronic device 100 , the cover plate 146 can make the light generated by the display area 1443 emit.

Please refer to Fig. 11, in some embodiments, the inner surface 1222 is formed with a plurality of protrusions 1229, and the plurality of protrusions 1229 can increase the connection area between the anti-overflow strip 16 and the inner surface 1222, so that the anti-overflow strip 16 and the inner surface The connection of 1222 is firmer, preventing the anti-overflow strip 16 from falling off from the inner side 1222.

Please refer to FIG. 6 and FIG. 7 together. In some embodiments, the groove 122 is substantially rectangular, and the side wall 126 includes an inner side 1222. The inner side 1222 includes a long side 1223 and a short side 1225 connecting the long side 1223. A step 128 is formed on the side surface 1225 , both lateral ends of the cover plate 146 are indented relative to the edge of the display screen 144 , and both longitudinal sides of the cover plate 146 are protruded relative to the edge of the display screen 144 . The cover plate 146 is supported on the step 128 and bonded to the step 128 .

In this way, the step 128 acts as a support for the panel assembly 14 , which facilitates the stable connection of the panel assembly 14 to the casing 12 . Specifically, in this embodiment, the display screen 144 is located on one side of the step 128 .

In another embodiment, the short side 1225 can omit the step 128 and have the same structure as the long side 1223 , and also apply anti-spill glue and form the anti-spill strip 16 . The longitudinal ends of the cover plate 146 can also be retracted relative to the display screen 144 .

The present invention also provides a glue dispensing method. The glue dispensing method in the embodiment of the present invention can be used to manufacture the front case assembly 10 in the embodiment of the present invention. Specifically, the dispensing method of the embodiment of the present invention will be described in detail below.

Please refer to Fig. 8 and Fig. 9, the dispensing method of the embodiment of the present invention comprises the following steps:

S12 : Provide the casing 12 and the panel assembly 14 . The casing 12 includes a bottom wall 124 and a side wall 126 extending from a side of the bottom wall 124 . The bottom wall 124 and the side wall 126 define a groove 122 . The panel assembly 14 includes a display screen 144 and a cover 146 . The display screen 144 includes a display area 1443 and a non-display area 1444 surrounding the display area 1443 , the cover plate 146 covers the display area 1443 and is at least partially indented relative to the edge of the display screen 144 .

S14: providing anti-overflow glue on the inner side of the side wall 126 along the circumferential direction of the side wall 126;

S16: curing the anti-overflow glue to form at least one anti-overflow strip 16;

S18: set the panel assembly 14 in the groove 122, and the anti-overflow strip 16 seals the gap 11 between the side wall 126 and the edge 142 of the panel assembly 14;

S20: disposing caulking glue in the gap 11 between the top 1262 of the side wall 126 and the edge 142 of the panel assembly 14;

S22: curing the caulking glue to securely connect the casing 12 and the panel assembly 14 .

The glue dispensing method of the embodiment of the present invention pre-sets and cures the anti-overflow glue to form at least one anti-overflow strip 16, so that the anti-overflow strip 16 seals the gap 11 between the side wall 126 and the edge 142, which can prevent subsequent setting and curing When sealing the caulking glue on the shell 12 and the panel assembly 14 , the caulking glue seeps into the groove 122 to contaminate the shell 12 and/or the panel assembly 14 . In addition, the cover plate 146 is at least partially indented relative to the edge of the display screen 144 , which can increase the area ratio of the display area 1443 to the cover plate 146 and increase the screen ratio of the electronic device 100 .

Wherein, in step S14, the anti-overflow glue can be dispensed on the inner side of the side wall 126 by a glue dispenser. In step S16, the anti-overflow glue can be cured naturally or by other means. For example, when the anti-overflow glue is UV glue, the anti-overflow glue can be cured by irradiating the anti-overflow glue with ultraviolet rays.

In step S18 , the panel assembly 14 can be sucked by the suction cup, and then put into the groove 122 , and the anti-spill strip 16 is in contact with the edge 142 , so that the gap 11 between the side wall 126 and the edge 142 can be sealed. It should be pointed out that the anti-overflow strip 16 seals the gap 11 at the bottom of the side wall 126 and the edge 142 .

In step S20 , caulking glue can be dispensed in the upper part of the gap 11 by a glue dispenser.

In step S22, the curing method of the caulking glue may be the same as that of the anti-overflow glue.

In some embodiments, the groove 122 is substantially rectangular, and the sidewall 126 includes a long sidewall 1224 and a short sidewall 1226 connected to the long sidewall 1224 . Step S14 comprises the following steps:

Anti-spill glue is provided on the inner side of the long sidewall 1224 along the length direction of the long sidewall 1224 .

In this way, the anti-overflow glue can be disposed on the inner side of the long side wall 1224 of the side wall 126 .

In some embodiments, the step of disposing anti-spill glue on the inner side of the long sidewall 1224 along the length direction of the long sidewall 1224 includes the following steps:

The anti-spill glue is continuously provided on the inner side of the long sidewall 1224 along the length direction of the long sidewall 1224 .

In this way, the size of the long sidewall 1224 is relatively large, and the anti-overflow strip 16 is arranged on the long sidewall 1224 along the length direction of the long sidewall 1224 to help seal the gap 11 between the sidewall 126 and the edge 1226 . In addition, the anti-overflow glue is continuously distributed on the long side wall 1224, so that the anti-overflow strip 16 after the anti-overflow glue is solidified is continuous on the long side wall 1224, preventing the anti-overflow caused by the discontinuous dot coating of the anti-overflow strip 16 The inability of the strip 16 to form a continuous sealing ring makes sealing the gap 11 between the side wall 126 and the edge 142 less effective.

In some embodiments, the anti-spill glue includes silicone glue.

Silicone glue has strong adhesion and good moisture resistance. Using silicone glue as the anti-overflow glue can make the anti-overflow strip 16 formed by curing the anti-overflow glue better in airtightness and moisture resistance. In addition, the silicone glue can also adapt to large temperature changes, so that the anti-overflow strip 16 will not reduce the sealing effect due to temperature changes. Of course, the caulking glue can also be silicone glue. Anti-spill glue and caulking glue can also be UV glue and other glues with good fluidity.

In some embodiments, step S16 includes the following steps:

Cure the anti-spill glue in an environment of 20-25°C for more than five minutes.

In one example, the anti-spill glue is cured in an environment of 20°C, and the curing time is 15 minutes; in another example, the anti-spill glue is cured in an environment of 22°C, and the curing time is 12 minutes; in yet another example , Curing the anti-spill glue in an environment of 25°C, the curing time is 6 minutes. The curing temperature in the range of 20-25° C. and the curing time in the range of more than five minutes are not specifically limited here.

In this way, 20-25° C. is a normal temperature environment, and curing the anti-overflow glue in a normal temperature environment makes the curing conditions of the anti-overflow glue simple and easy to implement, thereby reducing the manufacturing cost of the front case assembly 10 .

In some embodiments, the curing time of the anti-spill glue is less than the complete curing time of the anti-spill glue. In one example, the full curing time of the anti-overflow glue is greater than 25 minutes, while in the present invention, the anti-overflow glue has a curing time of 10 minutes.

In this way, after the anti-overflow glue is solidified for a period of time, the panel assembly 14 is arranged in the groove 122, so that the tightness between the panel assembly 14 and the groove 122 can be compared with that of the panel assembly 14 when the anti-overflow glue is not cured. The tightness of the case in the groove 122 is small, which facilitates disassembly in the subsequent maintenance process. In addition, before the anti-overflow glue is completely cured, the panel assembly 14 is arranged in the groove 122, which can avoid the poor sealing effect caused by the reduced fluidity of the anti-overflow glue due to the complete curing of the anti-overflow glue.

It can be understood that after the anti-overflow glue is completely cured, the anti-overflow glue loses its fluidity. At this time, the panel assembly 14 is set in the groove 122, and the anti-overflow glue cannot be deformed according to the extrusion of the panel assembly 14 and the groove 122. Better sealing effect. In addition, the anti-overflow strip 16 formed by the fully cured anti-overflow glue is not smooth and has a certain hardness, which will cause obstacles when the panel assembly 14 is placed into the groove 122 .

In some embodiments, the recess 122 is generally rectangular, and the sidewall 126 includes an inner side 1222 including a long side 1224 and a short side 1226 connecting the long side 1224 . The short side 1226 is formed with a step 128 , and the step 128 includes a stepped surface 1282 , a lower step 1284 connecting the stepped surface 1282 and the long side 1224 , and an upper step 1286 connected to the stepped surface 1282 . Step S14 comprises the following steps:

The anti-overflow glue is continuously arranged on the step bottom 1284 along the length direction of the step bottom 1284 .

In this way, the anti-overflow glue can be continuously distributed on the bottom of the step 1284, so that the anti-overflow strip 16 after the anti-overflow glue is cured is continuous on the bottom of the step 1284, preventing the anti-overflow caused by the discontinuous dot coating of the anti-overflow strip 16 The inability of the strip 16 to form a continuous sealing ring makes sealing the gap 11 between the side wall 126 and the edge 142 less effective.

It can be understood that the anti-overflow glue coated on the long sidewall 1224 and the short sidewall 1226 is continuous, so that the anti-overflow strip 16 formed after the anti-overflow glue coated along the circumference of the inner surface 1222 is cured can form a Closed seal.

Referring to FIG. 10 , in some embodiments, both lateral ends of the cover plate 146 are indented relative to the edge of the display screen 144 , and both longitudinal sides of the cover plate 146 are protruded relative to the edge of the display screen 144 . Step S18 comprises the following steps:

Adhesive glue is set on the step surface 1282;

supporting the cover plate 146 on the stepped surface 1282; and

The bonding glue is cured to bond the stepped surface 1282 and the cover plate 146 .

In this way, the panel assembly 14 is supported and fixed on the stepped surface 1282 by the adhesive strip 19 formed by curing the adhesive glue. The step 128 acts as a support for the cover plate 146 , which facilitates the stable connection of the panel assembly 14 to the housing 12 .

Specifically, the components of the bonding glue and the caulking glue may be the same, for example, both are the above-mentioned silicone glue. In addition, the display screen 144 and the bottom of the step 1284 can be bonded by the anti-overflow strip 16 formed by curing the anti-overflow glue.

In certain embodiments, the edge 142 of the panel assembly 14 includes a cover edge 1462 and a display edge 1442 . Step S20 includes:

providing caulking glue in the gap 11 between the top 1262 of the side wall 126 and the edge 1462 of the cover;

The curing caulking glue comprises:

The caulking glue is cured to securely connect the shell 12 and the cover edge 1462 .

In this way, the casing 12 and the cover plate edge 1462 are connected and fixed by the caulking glue 18 formed by curing the caulking glue, so that the panel assembly 14 is fixed in the groove 122 .

In some embodiments, the slit 11 is formed with an upward facing opening 112, and step S20 includes the following steps:

Put caulking glue into the gap 11 through the opening 112 .

The dispensing head is generally in the shape of a needle, and can put caulking glue into the gap 11 through the opening 112 . In one example, the front shell assembly 10 may be fixed with a clamp first, and then the glue dispensing head moves along a circle of the gap 11 to put caulking glue into the gap 11 through the opening 112 . In this way, the filling of the caulking glue is realized.

In some embodiments, the cured caulk comprises:

Cure the caulk in an environment of 20-25°C for more than five minutes.

In one example, the caulking glue is cured at 20°C for 15 minutes; in another example, the caulking glue is cured at 22°C for 12 minutes; and in yet another example , Cure the caulking glue in an environment of 25°C, and the curing time is 6 minutes. The curing temperature in the range of 20-25° C. and the curing time in the range of more than five minutes are not specifically limited here.

In this way, the curing of the caulking glue is realized. It can be understood that after the caulking glue is completely cured, the caulking glue loses its fluidity, and the fully cured caulking strip 18 has a certain hardness, so that the subsequent removal of the caulking on the surface 148 of the panel assembly 14 and the outer side 121 of the housing 12 The glue is inconvenient and may even damage the surface 148 of the panel assembly 14 and the outside 121 of the housing 12 during removal. The caulking glue cured in the environment of 20-25° C. for more than five minutes has not yet reached a fully cured state, which is beneficial for subsequent removal of the caulking glue located on the surface 148 of the panel assembly 14 and the outer side 121 of the housing 12 . In addition, 20-25° C. is a normal temperature environment, curing the caulking glue in a normal temperature environment makes the curing conditions of the caulking glue simple and easy to implement, thereby reducing the manufacturing cost of the front case assembly 10 .

In some embodiments, the dispensing method also includes the following steps after curing the caulking glue:

The residual glue (not shown) on the surface 148 of the panel assembly 14 and the outer side 121 of the casing 12 is removed.

During the process of dotting the caulking glue into the gap 11 from the opening 112, since the gap 11 is very narrow, when the amount of glue flowing out from the dispensing head is too much, the caulking glue is likely to overflow to the outer side 121 of the housing 12 and the panel assembly Surface 148 of 14 forms residual glue. Therefore, after curing the caulking glue, the residual glue needs to be wiped off, so that there is no residual glue on the outer side 121 of the casing 12 and the surface 148 of the panel assembly 14 .

In some embodiments, the step of removing residual glue on the surface 148 of the panel assembly 14 and the exterior side 121 of the housing 12 includes the following steps:

Use a lint-free cloth to wipe off the residual glue on the surface 148 of the panel assembly 14 and the outer side 121 of the housing 12 .

The surface of the dust-free cloth is soft and has good cleaning efficiency. Using the dust-free cloth to wipe off the caulking glue can obtain higher cleaning efficiency without damaging the surface 148 of the panel assembly 14 and the outer side 121 of the housing 12 . In one example, the front shell assembly 10 can be fixed with a clamp first, then the dust-free cloth is clamped by the manipulator, and finally the manipulator is controlled to move to wipe off the caulking glue on the surface 148 of the panel assembly 14 and the outer side 121 of the housing 12 .
