Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a display screen with a metal frame and a gluing device thereof. Background Art

[0002] During the assembly process of the display screen, there is a step of installing the screen assembly into the bottom shell, and the bottom surface of the screen assembly is bonded to the convex edge on the frame of the bottom shell, so as to fix the screen assembly to the bottom shell.

[0003] In the actual assembly process, the common practice in the industry is to apply glue on the convex edge and then assemble the screen assembly into the bottom shell. This method of applying glue first and then pressing requires precise control of the amount of glue. If there is too much glue, glue overflow will occur, resulting in the need to add a glue overflow removal station later. If there is too little glue, there will be a problem of unreliable bonding between the screen assembly and the bottom shell. The precise control of the amount of glue requires multiple experiments, which will undoubtedly cause a lot of waste of manpower and material resources.

[0004] In addition, in order to reduce the thickness of the frame and improve the texture of the frame, some displays will use metal frames. Summary of the invention

[0005] The technical problem solved by the present invention is to provide a display screen with a metal frame which can reduce the difficulty of controlling glue liquid, and a glue application device which can improve the glue application efficiency of the display screen with a metal frame.

[0006] In order to solve the above technical problems, the first technical solution adopted by the present invention is: a display screen with a metal frame, comprising a bottom shell and a screen body assembly, the bottom shell comprising a metal frame, the inner wall of the metal frame having a supporting protrusion extending inward, the screen body assembly being placed in the bottom shell and supported by the supporting protrusion, the top surface of the supporting protrusion being provided with a glue groove, the metal frame comprising a first side edge and a second side edge arranged opposite to each other, the outer wall of the first side edge having a glue injection hole connected to the glue groove, the outer wall of the second side edge having an exhaust hole connected to the glue groove, the exhaust hole being arranged at an angle, the end of the exhaust hole away from the glue groove being an exhaust port, the lower edge of the exhaust port being higher than the top surface of the supporting protrusion, the depth of the glue groove gradually increasing from the area connected to the glue injection hole to the area connected to the exhaust hole, and the glue groove being used for pouring glue liquid contacting the bottom surface of the screen body assembly.

[0007] In order to solve the above technical problems, the second technical solution adopted by the present invention is: a gluing device is used to glue the display screen, and the display screen is the above-mentioned display screen with a metal frame; the gluing device includes a table, a first positioning bar, a second positioning bar, a third positioning bar, a fourth positioning bar, a first driving member, a second driving member, a third driving member and a glue injection head, the first positioning bar and the second positioning bar are arranged opposite to each other, the third positioning bar and the fourth positioning bar are arranged opposite to each other, the table has a placement area for placing the display screen, the first positioning bar, the second positioning bar, the third positioning bar and the fourth positioning bar are arranged around the placement area, the first positioning bar, the second positioning bar, the third positioning bar and the fourth positioning bar are all made of heat-conducting material, the first positioning bar, the second positioning bar, the third positioning bar and the fourth positioning bar are respectively embedded with heating elements, the second positioning bar and the third positioning bar are fixedly arranged at On the table, the second positioning strip is provided with an exhaust groove, and when the second positioning strip contacts the outer wall of the second side of the display screen, the exhaust groove is connected to the exhaust hole, the second driving member is arranged on the table and connected to the fourth positioning strip to drive the fourth positioning strip to approach or move away from the third positioning strip, the first driving member is arranged on the table and connected to the first positioning strip to drive the first positioning strip to approach or move away from the second positioning strip, the third driving member is arranged on the table and connected to the glue injection head to drive the glue injection head to approach or move away from the second positioning strip, the first positioning strip is provided with an avoidance groove, when the first positioning strip contacts the outer wall of the first side of the display screen, the avoidance groove is connected to the glue injection hole, the glue injection head is located in the avoidance groove and the glue injection port of the glue injection head extends into the glue injection hole on the first side.

[0008] The beneficial effects of the present invention are:

[0009] The display screen with a metal frame adopts a glue injection method to connect the supporting convex edge of the bottom shell and the screen body assembly. The glue is injected from the glue injection hole, and the air in the glue groove is discharged from the exhaust hole. The lower edge of the exhaust port is higher than the top surface of the supporting convex edge, so that the injected glue can effectively fill the glue groove, ensuring the stability of the bonding between the bottom shell and the screen body assembly. Moreover, by observing the glue overflow from the exhaust port, it is also possible to clearly know whether the glue groove is filled with glue, which greatly reduces the difficulty of controlling the glue injection amount and facilitates the assembly of the screen body assembly and the bottom shell. Moreover, even if glue overflow occurs, since there is only one exhaust hole, the overflowed glue from the exhaust hole is easy to clean, which further facilitates the assembly and production of the display screen. In addition, since the glue groove is inclined, the depth of the glue groove near the glue injection hole is shallow, and the depth of the glue groove near the exhaust hole is deep, which can make the glue in the glue groove flow more smoothly and is more conducive to the glue filling the glue groove.

[0010] The gluing device can automatically complete the glue injection work in the glue groove in the bottom shell, which is beneficial to improving the assembly efficiency of the display screen. The first positioning bar, the second positioning bar, the third positioning bar and the fourth positioning bar are embedded with heating elements. The heat generated by the heating elements can be transferred to the glue in the glue groove via the metal frame, so that the glue can maintain a certain fluidity, so that the glue can better fill the glue groove, thereby more effectively ensuring the stability of the connection between the screen assembly and the bottom shell.

[0029] Embodiment 1

[0030] Please refer to Figures 1 to 3 , Embodiment 1 of the present invention is: Figure 1 and Figure 2As shown, a display screen with a metal frame includes a bottom shell 1 and a screen assembly 2, wherein the bottom shell 1 includes a metal frame 11, and the inner wall of the metal frame 11 has a supporting protrusion 12 extending inwardly, and optionally, the metal frame 11 and the supporting protrusion 12 are an integral structure formed by integral processing; the screen assembly 2 is placed in the bottom shell 1 and supported by the supporting protrusion 12, and the top surface of the supporting protrusion 12 is provided with a glue groove 13, and the metal frame 11 includes a first side edge 111 and a second side edge 112 arranged opposite to each other, and the outer wall of the first side edge 111 has a glue injection hole 113 connected to the glue groove 13, and the outer wall of the second side edge 112 has a There is an exhaust hole 114 connected to the glue groove 13, and the exhaust hole 114 is inclined. The end of the exhaust hole 114 away from the glue groove 13 is an exhaust port 1141 (i.e., the connection point between the exhaust hole 114 and the outer wall of the second side 112), and the lower edge of the exhaust port 1141 is higher than the top surface of the supporting protrusion 12. The depth of the glue groove 13 gradually increases from the area connected to the glue injection hole 113 to the area connected to the exhaust hole 114. In other words, the bottom surface of the glue groove 13 is a sloped surface, and the glue groove 13 is used to inject glue that contacts the bottom surface of the screen body assembly 2, so that the screen body and the supporting protrusion 12 can be bonded and fixed.

[0031] The top surface of the glue injection hole 113 is lower than the top surface of the supporting protrusion 12 , which ensures that all the glue can be injected into the glue groove 13 without entering the gap between the screen assembly 2 and the inner wall of the first side 111 .

[0032] The glue injection hole 113 is set corresponding to the middle area of ​​the first side 111, and the exhaust hole 114 is set corresponding to the middle area of ​​the second side 112, so that the two paths of glue can flow the same distance in the glue groove 13, thereby avoiding the phenomenon that one path of glue flows to the exhaust hole 114 while the other path of glue has not yet reached the exhaust hole 114, which in turn causes a local lack of glue in the glue groove 13.

[0033] The glue groove 13 is arranged close to the metal frame 11, so that the top surface area of ​​the supporting protrusion 12 located inside the glue groove 13 has a sufficient width, thereby preventing the glue in the glue groove 13 from overflowing into the bottom shell 1, so that other electronic devices installed in the bottom shell 1 are contaminated.

[0034] A transition groove 121 is provided in the region of the support protrusion 12 between the glue groove 13 and the inner wall of the second side edge 112. The transition groove 121 is connected to the top surface of the support protrusion 12, and the transition groove 121 is connected to the exhaust hole 114 and the glue groove 13. Except for the transition groove 121 region, the edge of the bottom surface of the screen assembly 2 can be supported by the support protrusion 12, so that the edge of the screen assembly 2 can withstand a certain pressure, which is conducive to reducing the risk of damage to the screen assembly 2 when the user uses it, and the glue solidified in the transition groove 121 can contact the bottom surface of the screen assembly 2, thereby increasing the bonding area of ​​the screen assembly 2, and also helping to improve the connection strength between the screen assembly 2 and the bottom shell 1.

[0035] In order to facilitate the assembly of the screen assembly 2 and the bottom shell 1 in the display screen with a metal frame, this embodiment further provides a gluing device, which is used to glue the display screen with a metal frame.

The second driving member 52 is arranged on the table 3 and connected to the fourth positioning bar 44 to drive the fourth positioning bar 44 to approach or move away from the third positioning bar 43. The first driving member 51 is arranged on the table 3 and connected to the first positioning bar 41 to drive the first positioning bar 41 to approach or move away from the second positioning bar 42. The third driving member 53 The glue injection head 54 is arranged on the table 3 and connected to drive the glue injection head 54 to approach or move away from the second positioning strip 42. The first positioning strip 41 is provided with an avoidance groove 411. When the first positioning strip 41 contacts the outer wall of the first side edge 111 of the display screen, the avoidance groove 411 is connected to the glue injection hole 113. The glue injection head 54 is located in the avoidance groove 411 and the glue injection port 541 of the glue injection head 54 extends into the glue injection hole 113 on the first side edge 111.

[0037] In one or more embodiments, the first driving member 51 , the second driving member 52 , and the third driving member 53 are cylinders or electric push rods.

[0038] Optionally, the heating element 6 is a heating resistor wire, and the heat generated by the heating element 6 is transferred to the metal frame 11 via the first positioning bar 41 / the second positioning bar 42 / the third positioning bar 43 / the fourth positioning bar 44, and then absorbed by the glue flowing in the glue groove 13.

[0039] In this embodiment, the first positioning bar 41, the second positioning bar 42, the third positioning bar 43 and the fourth positioning bar 44 are all made of iron alloy. In other embodiments, the first positioning bar 41, the second positioning bar 42, the third positioning bar 43 and the fourth positioning bar 44 can also be made of other materials with good thermal conductivity.

[0040] Preferably, the heating element 6 is arranged corresponding to the glue groove 13. Specifically, the distance between the heating element 6 and the top surface of the table 3 is substantially the same as the distance between the glue groove 13 and the top surface of the table 3, so that the heat generated by the heating element 6 can be better transferred to the glue groove 13, which is conducive to reducing heat energy waste.

[0041] The gluing device also includes a screen pressing mechanism 7, which includes a connected downward pressing drive member 71 and a downward pressing plate 72.

Then the downward pressing driving member 71 drives the lower pressing plate 72 to press down the screen assembly 2, so that the bottom surface of the screen assembly 2 and the top surface of the supporting convex edge 12 form a nearly sealed state. Finally, the third driving member 53 drives the glue injection head 54 to move in the direction close to the second positioning bar 42, so that the glue injection port 541 of the glue injection head 54 is inserted into the glue injection hole 113, and then glue is injected. At the same time, the heating element 6 keeps heating until the glue liquid is observed at the exhaust port 1141 and the glue injection is stopped.
