The electronic device 100 includes a body 20, and the front case assembly 10 is disposed on the body 20. The electronic device 100 includes, but is not limited to, a cell phone, a tablet computer, or a wearable device. The present embodiment is described in detail by taking a mobile phone as an example.
Specifically, the electronic device 100 further includes a battery cover (not shown) respectively disposed on the opposite sides of the housing 12 and the panel assembly 14.
Referring to fig. 2-5, a display screen assembly 10 according to an embodiment of the present invention includes a housing 12, a panel assembly 14, a spill strip 16, and a joint strip 18.
The housing 12 includes a bottom wall 124 and a side wall 126 extending from an edge of the bottom wall 124, the bottom wall 124 and the side wall 126 define a groove 122, the side wall 126 defines the glue injection hole 13 communicating with the groove 122, and the side wall 126 includes an inner side 1222. The panel assembly 14 is disposed in the recess 122. The panel assembly 14 includes an edge 142, a gap 11 is formed between the side wall 126 and the edge 142, the gap 11 is communicated with the glue injection hole 13, and the glue injection hole 13 is used for injecting the caulking glue into the gap 11. The spill strip 16 is arranged on the inner side 1222 in the circumferential direction of the side wall 126. The joint strip 18 is filled in the gap 11. The joint compound 18 is formed by curing the joint compound and fixedly connects the housing 12 and the panel assembly 14.
In the display screen assembly 10 of the present invention, the gap 11 is filled with the filling glue through the glue injection hole 13 formed in the side wall 126 and connected to the groove 122, which is not only beneficial to filling the gap 11 with the filling glue, but also beneficial to designing the size of the gap 11 to be small, and in addition, the overflow prevention strip 16 prevents the filling glue from penetrating into the bottom of the groove 122 to contaminate the housing 12 and/or the panel assembly 14.
The housing 12 is substantially rectangular parallelepiped, and the housing 12 is a carrier of the electronic device 100 and is used for carrying most parts of the electronic device 100. The housing 12 may be made of plastic, metal, or plastic and metal by an in-mold injection molding process. In one example, the bottom wall 124 is made of metal and the side walls 126 are made of plastic, and the bottom wall 124 can be placed in a mold, and then the side walls 126 can be formed by injecting molten plastic into the mold and solidifying the plastic, thereby obtaining the housing 12.
Referring to fig. 6, in some embodiments, the side wall 126 is substantially rectangular, the side wall 126 includes a long side wall 1224 and a short side wall 1226 connected to the long side wall 1224, the number of glue injection holes 13 is plural, and the plural glue injection holes 13 are spaced apart along the length direction of the long side wall 1224 at the length edge of the bottom wall 124.
The plurality of glue injection holes 13 are arranged at intervals on the length edge of the side wall 126, so that when the filling glue is placed into the gap 11 through the glue injection holes 13, the situation that the filling glue cannot flow into each position of the gap 11 due to poor flowability of the filling glue can be avoided. In addition, can practice thrift sealed glue when can so stopping up injecting glue hole 13 after the point is glued and is accomplished.
In production, the display screen assembly 10 may be first fixed using a jig, and then the dispensing head is moved to fill the gap 11 with caulking glue through each glue injection hole 13. It is also possible to use a plurality of dispensing heads while filling the gap 11 with caulking glue through a plurality of dispensing holes 13.
Of course, in some embodiments, the short sidewalls 1226 may also be perforated with glue injection holes. The glue injection holes on the short sidewalls 1226 may be identical in structure and arrangement to the glue injection holes 13 on the long sidewalls 1224.
The depth direction of the glue injection hole 13 may be the same as the thickness of the sidewall 126, and the depth direction of the glue injection hole 13 may be inclined to the thickness of the sidewall 126.
Referring to fig. 7, in some embodiments, the inner side 1222 is formed with a plurality of protrusions 1229, and the plurality of protrusions 1229 can increase the connection area between the spill strip 16 and the inner side 1222, so that the spill strip 16 is more firmly connected to the inner side 1222 and the spill strip 16 is prevented from falling off the inner side 1222.
In some embodiments, the display screen assembly 10 includes a sealant (not shown) that seals the glue injection holes 13. In this way, sealing of the glue injection hole 13 can be achieved.
It will be appreciated that after filling the gap 11 with the caulking glue through the glue injection hole 13 and curing the caulking glue, the glue injection hole 13 needs to be blocked to prevent dirt such as dust from entering the panel assembly 14 through the glue injection hole 13 to affect the function of the panel assembly 14.
In some embodiments, the recess 122 forms a floor 1228 connected to the sidewalls 126, and the sidewalls 126 are planar perpendicular to the floor 1228. Side wall 126 is located on side wall 126 and bottom surface 1228 is located on bottom wall 124, as shown in fig. 5.
In some embodiments, the recess 122 forms a bottom surface 1228 connected to the side walls 126, and the side walls 126 are slopes extending upward and outward from edges of the bottom surface 1228.
The sidewalls 126 may be perpendicular to the bottom surface 1228, or may extend upwardly and outwardly from the edges of the bottom surface 1228, and the particular configuration of the display screen assembly 10 may be selected as desired.
In some embodiments, the panel assembly 14 includes a touch panel 144 and a cover 146 overlying the touch panel 144. The lateral dimension of the cover 146 is greater than the lateral dimension of the touch panel 144 such that the edge 142 forms a stepped surface between the cover 146 and the touch panel 144. Edge 142 includes cover edge 1462 and touch pad edge 1442. The joint strip 18 fixedly connects the cover edge 1462 and the side wall 126 as shown in fig. 5.
In this manner, the cover edge 1462 and the side wall 126 of the recess 122 are connected by the joint strip 18, thereby fixedly connecting the panel assembly 14 to the housing 12.
Specifically, the material of the cover plate 146 may be made of a light-transmitting material such as glass, ceramic, or sapphire. Since the cover plate 146 is an input part of the electronic device 100, the cover plate 146 is often contacted by impact, scratch, or the like. For example, when the user places the electronic device 100 in a pocket, the cover plate 146 may be scratched by a key in the pocket of the user and damaged. Therefore, the material of the cover plate 146 may be a material with a relatively high hardness, such as the above sapphire material. Or a hardened layer may be formed on the surface of the cover plate 146 to improve scratch resistance of the cover plate 146.
Specifically, the touch panel 144 includes a display module (not shown) and a touch layer (not shown) disposed on the display module. The display Module is, for example, a liquid crystal display Module (LCD Module, LCM), and of course, the display Module may also be a flexible display Module. The touch layer is used for receiving touch input of a user so as to generate a signal for controlling the content displayed by the display module.
The touch panel 144 and the cover plate 146 are adhered and fixed together by, for example, optical Adhesive (OCA), which not only adheres and fixes the touch panel 144 and the cover plate 146, but also transmits light emitted from the touch panel 144.
In one example, the panel assembly 14 may be formed by: the touch panel 144 and the cover plate 146 are provided, then the optical adhesive is coated on the touch panel 144, and finally the cover plate 146 is attached to the optical adhesive, so that the cover plate 146 and the touch panel 144 are fixed together.
In certain embodiments, spill guard bars 16 are disposed on the long sidewalls 1224 along the length of the long sidewalls 1224. As such, the long sidewalls 1224 are larger in size, and the placement of the spill guard 16 on the long sidewalls 1224 along the length of the long sidewalls 1224 facilitates sealing the gap 11 between the inner side 1222 and the edge 1226.
Referring also to fig. 2 and 8-9, in some embodiments, recess 122 is generally rectangular, sidewall 126 includes an inner side 1222, inner side 1222 includes a long side 1223 and a short side 1225 connected to long side 1223, short side 1225 is formed with step 128, and step 128 includes a step 1282, a step lower surface 1284 connected to step 1282 and long side 1223, and a step upper surface 1286 connected to step 1282.
In certain embodiments, recess 122 is generally rectangular, side walls 126 include inner sides 1222, short side walls 1226 are formed with steps 128, and panel assembly 14 is supported on steps 128 and adhesively secured to steps 128.
In this manner, the step 128 acts as a support for the panel assembly 14, facilitating stable attachment of the panel assembly 14 to the housing 12. Specifically, in the present embodiment, the cover plate 146 is supported on the step 128, and the touch panel 144 is located on one side of the step 128. Because the panel assembly 14 is adhesively secured to the step 128, the provision of the spill strip 16 on the step underside 1284 prevents adhesive glue from seeping into the recess 122 to contaminate the housing 12 and/or the panel assembly 14.
In other embodiments, the short sidewalls 1226 may omit the step 128 and have the same structure as the long sidewalls 1224.
The invention also provides a manufacturing method of the display screen assembly, and the manufacturing method of the display screen assembly of the embodiment of the invention can be used for manufacturing and forming the display screen assembly 10 of the embodiment of the invention. Specifically, the method for manufacturing the display panel assembly according to the embodiment of the present invention will be described in detail below.

According to the manufacturing method of the display screen assembly, the gap 11 is filled with the filling glue through the glue injection hole 13 which is formed in the side wall 126 and is communicated with the groove 122, so that the filling glue can be injected into the narrow gap 11, the size of the gap 11 can be designed to be small, and in addition, the anti-overflow strip 16 enables the filling glue not to permeate into the bottom of the groove 122 to pollute the shell 12 and/or the panel assembly 14.
Here, in step S14, the overflow preventing bar 16 is formed by curing an overflow preventing glue, which may be dispensed on the inner side 1222 of the sidewall 126 through a dispenser. The anti-overflow glue can be naturally cured or cured in other ways. For example, when the anti-overflow glue is UV glue, the anti-overflow glue may be irradiated by ultraviolet rays to be cured. The spill-proof glue is, for example, a silicone glue. The silicone adhesive has strong bonding force and good moisture resistance. The silicone adhesive is used as the anti-overflow glue, so that the sealing performance and the moisture resistance of the anti-overflow strip 16 formed by curing the anti-overflow glue can be better. In addition, the silicone adhesive can also accommodate large temperature changes, so that the spill strip 16 does not degrade the sealing effect due to the temperature changes. Of course, the caulking glue may also be a silicone glue. The anti-overflow glue and the joint filling glue can also be other glues with better fluidity, such as UV glue and the like.
The steps of curing the anti-overflow glue to form the anti-overflow strip 16 may be: and curing the anti-overflow glue in an environment of 20-25 ℃ for more than five minutes. In one example, the anti-overflow glue is cured in an environment of 20 ℃ for 15 minutes; in another example, the spill-proof glue is cured in an environment at 22 ℃ for 12 minutes; in yet another example, the flood-proof glue is cured in an environment at 25 ℃ for a curing time of 6 minutes. The curing temperature in the range of 20 to 25 c and the curing time in the range of more than five minutes are not particularly limited herein.
Thus, the temperature of 20-25 ℃ is a normal temperature environment, and the anti-overflow glue is cured in the normal temperature environment, so that the curing condition of the anti-overflow glue is simple and easy to realize, and the manufacturing cost of the front shell assembly 10 is reduced.
In certain embodiments, the curing time of the spill proof glue is less than the full curing time of the spill proof glue. In one example, the time for complete curing of the spill proof glue is greater than 25min, whereas in the present invention, the time for curing of the spill proof glue is 10 min.
As such, after the anti-spill glue is cured for a period of time, the panel assembly 14 is disposed in the recess 122, such that the closeness between the panel assembly 14 and the recess 122 may be less than if the panel assembly 14 were disposed in the recess 122 when the anti-spill glue had not been cured, facilitating disassembly during subsequent maintenance. Further, by disposing the panel assembly 14 in the recess 122 before the spill-proof glue is completely cured, poor sealing due to reduced fluidity caused by the complete curing of the spill-proof glue can be avoided.
It will be appreciated that after the glue has completely cured, the glue loses its flowability, and by placing the panel assembly 14 in the recess 122, the glue cannot deform to achieve a better sealing effect due to the squeezing of the panel assembly 14 and the recess 122. In addition, the spill strip 16 formed by the fully cured spill-resistant glue is not flat and has a hardness that can cause an obstruction when the panel assembly 14 is placed into the recess 122.
Here, in step S16, the panel assembly 14 may be sucked by the suction cup and then loaded into the groove 122. In step S18, a caulking glue may be injected into the slit 11 through the glue injection hole 13 using a dispenser. In step S20, the caulking glue may be cured naturally or in other manners. For example, when the caulking glue is a UV glue, the caulking glue may be irradiated by ultraviolet rays to be cured.
In certain embodiments, the spill strip comprises foam.
At this point, the foam may be attached to the side wall 126 by double sided tape. The foam is resilient and may be used as a spill strip 16 to not only prevent subsequent caulking glue from seeping into the groove 122 and contaminating the housing 12 and/or panel assembly 14, but also to act as a cushioning material to protect the panel assembly 14 when the housing 12 and/or panel assembly 14 is impacted. In addition, the foam is simple and light, which can reduce the weight of the housing 12 and the panel assembly 14 while improving the production efficiency and reducing the cost.
In certain embodiments, the recess 122 is generally rectangular, and the sidewalls 126 include long sidewalls 1224 and short sidewalls 1226 connecting the long sidewalls 1224. Step S14 includes the following steps:
spill bars 16 are provided on the inner sides of the long side walls 1224 along the length direction of the long side walls 1224.
In this manner, it may be achieved that the anti-overflow glue is arranged on the inner side of the long side walls 1224 of the side walls 126, which may prevent the flow of the caulking glue from the long side walls 1224 to the bottom of the groove 122.
In some embodiments, the step of providing the overfill prevention glue on the inner side of the long side walls 1224 along the length of the long side walls 1224 comprises the steps of:
the spill prevention bars 16 are provided continuously on the inner sides of the long side walls 1224 along the length direction of the long side walls 1224.
As such, the long sidewalls 1224 are larger in size, and the placement of the spill guard 16 on the long sidewalls 1224 along the length of the long sidewalls 1224 facilitates sealing the gap 11 between the sidewall 126 and the edge 1226. Furthermore, the spill guard 16 is continuously distributed over the long side walls 1224, which prevents the spill guard 16 from failing to form a continuous sealing ring due to discontinuities in the spill guard 16, resulting in poor sealing of the gap 11 between the side wall 126 and the rim 142.
In some embodiments, the recess 122 is generally rectangular and the medial side 1222 includes a long side 1224 and a short side 1226 connecting the long sides 1224. The short side surface 1226 is formed with a step 128, and the step 128 includes a step surface 1282, a step lower surface 1284 connecting the step surface 1282 and the long side surface 1224, and a step upper surface 1286 connecting the step surface 1282. Step S14 includes the following steps:
In this manner, spill strip 16 is continuous on step underside 1284, preventing spill strip 16 from failing to form a continuous seal ring due to the discontinuous spot coating of spill strip 16, resulting in a poor seal of gap 11 between sidewall 126 and rim 142.
It will be appreciated that the spill guard strips 16 arranged on the long side walls 1224 and the short side walls 1226 are continuous, so that the spill guard strips 16 arranged along the circumference of the inner side 1222 can form a closed sealing ring.
Referring to fig. 10, in some embodiments, step S18 includes the following steps:
arranging bonding glue on the step surface 1282;
supporting the panel assembly 14 on the step surface 1282; and
the bonding glue is cured to bond the step surface 1282 and the panel assembly 14.
In this manner, the panel assembly 14 is seated against and secured to the stepped surface 1282 by the adhesive bead 19 formed by curing the adhesive glue. The step 128 acts as a support for the panel assembly 14 and facilitates stable attachment of the panel assembly 14 to the housing 12.
In particular, the bonding glue and the caulking glue may be of the same composition, e.g. both silicone glues described above. In addition, the panel assembly 14 includes a touch panel 144 and a cover plate 146 covering the touch panel 144, the longitudinal dimension of the cover plate 146 is larger than the longitudinal dimension of the touch panel 144, the cover plate 146 of the panel assembly 14 is rested on the step surface 1282, and the touch panel 144 and the step surface 1284 of the panel assembly 14 are adhered by the spill prevention strip 16.
In some embodiments, the panel assembly 14 includes a touch panel 144 and a cover plate 146 covering the touch panel 144, the cover plate 146 having a lateral dimension greater than the lateral dimension of the touch panel 144 such that the edge 142 forms a stepped surface between the cover plate 146 and the touch panel 144, the edge 142 including a cover plate edge 1462 and a touch panel edge 1442, and the step of filling the gap 11 with the caulking glue through the glue filling hole 13 includes the steps of:
filling gap-filling glue through glue-filling hole 13 to gap 11 between top 1262 of sidewall 126 and cover plate edge 1442;
the step of curing the caulking glue to fixedly connect the housing 12 and the panel assembly 14 includes:
the caulking glue is cured to fixedly connect the housing 12 and the cover plate edge 1442.
In this manner, the housing 12 and the cover edge 1462 are joined and secured by the caulk strip 18 formed by the curing of the caulk, thereby securing the panel assembly 14 within the recess 122.
The dispensing head is generally needle-shaped and can place the caulking glue into the gap 11 through the glue injection hole 13. In one example, the display screen assembly 10 may be secured using a clamp, and then the dispensing head moved along the dispensing hole 13 to place the caulking glue into the gap 11 through the dispensing hole 13. Thus, filling of the gap filling glue is realized.
In certain embodiments, the step of curing the caulking glue comprises the steps of:
the caulking glue is cured in an environment of 20-25 ℃ for more than five minutes.
In one example, the caulking glue is cured in an environment of 20 ℃ for 15 minutes; in another example, the caulking glue is cured in an environment of 22 ℃ for a 12 minute cure time; in yet another example, the underfill glue is cured in an environment at 25 ℃ for a cure time of 6 minutes. The curing temperature in the range of 20 to 25 c and the curing time in the range of more than five minutes are not particularly limited herein.
Thus, the solidification of the joint filling glue is realized. It will be appreciated that after the caulking glue has fully cured, the caulking glue loses fluidity and the fully cured caulking strip 18 has a degree of stiffness that makes subsequent removal of the caulking glue at the surface 148 of the panel assembly 14 and the outside 121 of the housing 12 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 for more than five minutes at 20-25 c has not yet reached a fully cured state facilitating subsequent removal of the caulking glue located on the surface 148 of the panel assembly 14 and the exterior side 121 of the housing 12. In addition, the temperature of 20-25 ℃ is a normal temperature environment, and the curing condition of the joint filling glue is simple and easy to realize by curing the joint filling glue in the normal temperature environment, so that the manufacturing cost of the display screen assembly 10 is reduced.
In some embodiments, the method for manufacturing a display screen assembly further includes the following steps after step S20:
sealing glue is provided in the glue injection hole 13 to seal the glue injection hole 13.
In this way, sealing of the glue injection hole 13 can be achieved. After the caulking glue is cured, the glue injection hole 13 serving as a passage for filling the caulking glue needs to be sealed to prevent dirt such as dust from entering the panel assembly 14 through the glue injection hole 13 to affect the function of the panel assembly 14. It will be appreciated that a glue with a poor flow should be used as the sealing glue. If glue with high fluidity is adopted as the sealing glue, the sealing glue can easily permeate into the shell 12 and the panel assembly 14 along the glue injection hole 13 to pollute the shell 12 and the panel assembly 14.
In some embodiments, the method for manufacturing a display screen assembly further includes the following steps after step S20:
the caulking glue located on the upper surface 148 of the panel assembly 14 and the exterior side 121 of the housing 12 is removed.
In the process of dispensing the caulking glue into the gap 11 from the dispensing hole 13, since the dispensing hole 13 is very narrow, when the dispensing amount flowing out from the dispensing head is too large, the caulking glue is easily overflowed to the outer side 121 of the housing 12. Therefore, after curing the caulking glue, the caulking glue also needs to be wiped off so that the outer side 121 of the housing 12 and the upper surface 148 of the panel assembly 14 no longer have the caulking glue.
In some embodiments, the step of removing the caulking glue located on the upper surface 148 of the panel assembly 14 and the exterior side 121 of the housing 12 comprises the steps of:
the caulking glue on the upper surface 148 of the panel assembly 14 and the exterior side 121 of the housing 12 is wiped off using a dust free cloth.
The dust cloth is soft in surface and has good cleaning efficiency, and the use of the dust cloth to wipe off the caulking glue can achieve higher cleaning efficiency without damaging the upper surface 148 of the panel assembly 14 and the outer side 121 of the housing 12. In one example, the display screen assembly 10 may be secured using a clamp, then a dust free cloth may be held by a robot arm, and finally the robot arm may be controlled to move to wipe the caulking glue located on the upper surface 148 of the panel assembly 14 and the exterior side 121 of the housing 12.
In some embodiments, the method for manufacturing a display screen assembly further includes the following steps after step S20:
the cured caulking glue located in the gap 11 is wiped so that the appearance of the cured caulking glue is substantially the same as the appearance of the housing.
The joint filling glue with higher viscosity in the gap 11 is wiped, so that the surface of the wiped joint filling glue is rough to be in a matte state, the appearance of the cured joint filling glue is approximately the same as that of the shell 12 which is usually in the matte state, and the coordination and consistency of the product appearance are facilitated.
