Description

Technical Field

[0001] The present invention relates to the technical field of panel full-lamination process, and in particular to a full-lamination device and a full-lamination method. Background Art

[0002] With the promotion of energy conservation and consumption reduction, green and energy-saving ink screens are increasingly used for outdoor displays. However, in actual applications, since the ink screen itself does not emit light, it needs to be visible in the sun. When there is no light at night, the display content of the ink screen cannot be viewed. It is necessary to add a front light guide plate to the surface of the ink screen to provide a light source. In order to ensure the display consistency of the front light guide plate, it is necessary to fill the front light guide plate and the ink screen with optical glue.

[0003] At present, glue is poured using a perfusion technology, that is, the glue is injected between the front light guide plate and the glass protective cover. However, since the material of the front light guide plate is relatively soft, when the glue is injected from the injection hole, the front light guide plate is usually squeezed and deformed, and the actual amount of glue used is 2-4 times more than the theoretical amount, resulting in an increase in manufacturing costs. At the same time, due to the limitation of the fluidity of the glue, the glue thickness will be uneven during the actual glue pouring process, affecting the uniform display effect. Summary of the invention

[0004] In view of this, the present invention provides a full-fitting device to solve the problem that currently glue is injected by injection technology, that is, the glue is injected between the front light guide plate and the glass protective cover plate. However, since the material of the front light guide plate is relatively soft, when the glue is injected from the injection hole, the front light guide plate is usually squeezed and deformed, and the actual amount of glue used is 2-4 times more than the theoretical amount, resulting in an increase in manufacturing costs. At the same time, due to the limitation of the fluidity of the glue, the glue thickness will be uneven during the actual glue injection process, affecting the uniform display effect.

[0005] In a first aspect, the present invention provides a full lamination device, comprising:

[0006] Base plate;

[0007] A pressure plate, the pressure plate is spaced apart from the bottom plate, and the pressure plate is provided with a pressure structure facing the bottom plate;

[0008] The pressure structure is suitable for discharging a pressurized airflow toward the to-be-assembled component placed between the bottom plate and the pressure plate, so as to suppress deformation of the to-be-assembled component during the glue injection process.

[0009] Beneficial effect: By setting up a pressure plate, it is ensured that during the glue injection process, the front light guide plate in the assembly part is always in a horizontal state to avoid deformation, so that the thickness of the glue on the entire surface is consistent, the assembly quality is improved, and the problem of uneven display after subsequent assembly of the ink screen is avoided. The actual amount of glue used is equal to the theoretical amount, which reduces the production and assembly costs.

[0010] In an optional embodiment, the pressure-applying structure includes a plurality of air holes and air flow channels, the air inlets of the air holes are connected to the air flow channels, and the output ends of the air holes are suitable for facing the parts to be assembled.

[0011] Beneficial effect: The air holes are facing the parts to be assembled, ensuring that the pressure of the gas discharged from each air hole is uniform.

[0012] In an optional embodiment, the air flow channel includes: a plurality of first air flow channels and a plurality of second air flow channels arranged to intersect with the first air flow channels, and the first air flow channels and the second air flow channels are interconnected;

[0013] Wherein, the air inlet end of the air hole is arranged at the intersection of the first air flow channel and the second air flow channel.

[0014] Beneficial effect: It ensures that each air hole can receive the gas with a certain pressure in the air flow channel, and ensures that the pressure of the gas discharged from each air hole is uniform.

[0015] In an optional embodiment, the first air flow channel and the second air flow channel intersect vertically so that the air flow channels are arranged in a mesh shape.

[0016] In an optional embodiment, the first airflow channel is opened in the pressure plate along the glue injection direction, and the plurality of first airflow channels are equidistantly arranged along a first direction perpendicular to the glue injection direction;

[0017] The second air flow channel is opened in the pressure plate along the first direction; along the glue injection direction, the distance between any two adjacent second air flow channels gradually increases.

[0018] Beneficial effect: By designing the distance between any two adjacent second airflow channels to gradually increase along the glue injection direction, the pressure on the upper surface of the front light guide plate along the glue injection direction is gradually reduced. That is, the left end close to the air inlet of the first airflow channel is subjected to greater pressure, while the right end is subjected to less pressure. By adjusting the ventilation pressure of the external air pump, the pressures on the upper and lower surfaces of the front light guide plate on the same vertical line offset each other, and the front light guide plate always tends to be horizontal to avoid deformation, so that the thickness of the glue on the entire surface is consistent, improving the assembly quality, avoiding the problem of uneven display after the subsequent assembly of the ink screen, and the actual amount of glue used is equal to the theoretical amount, reducing the production and assembly costs. At the same time, by gradually reducing the force on the upper surface of the front light guide plate from left to right, the air pressure on the left side can squeeze the glue directly below, and cooperate with the external glue injection device to accelerate the glue to move evenly toward the exhaust hole, thereby improving the glue injection efficiency.

[0019] In an optional embodiment, the full fitting device further comprises a spring guide rail, one end of which is connected to the base plate, and the other end of which is detachably connected to the pressure plate, and the spring guide rail is used to adjust the distance between the pressure plate and the spring guide rail.

[0020] In an optional embodiment, the pressure plate and the to-be-assembled parts are spaced apart so that a pressure gap exists between the pressure plate and the to-be-assembled parts.

[0021] Beneficial effect: It ensures that there is no contact between the pressure plate and the assembly to be assembled, and avoids the pressure plate causing scratches and other damages to the front light guide surface.

[0022] In an optional embodiment, the full fitting device further comprises a buckle, and the buckle is rotatably mounted on the bottom plate;

[0023] At least one pair of the snap fasteners is arranged on the bottom plate, and the snap fasteners can be snapped on the side edges of the to-be-assembled parts to fix the to-be-assembled parts after the glue injection on the bottom plate.

[0024] Beneficial effects: The clip is L-shaped. When it is clipped on both sides of the assembly, one side wall is attached to the side of the assembly and the other side is attached to the upper surface of the assembly. It can limit the position between the front light guide plate and the glass protection cover to ensure that the two do not deviate in the left and right directions, and can be used to adjust the thickness of the assembly. For different sizes of assembly, a pair of clips with different sizes and different installation distances can be designed on the bottom plate.

[0025] In an optional embodiment, the components to be assembled include: a front light guide plate and a glass protection cover plate, wherein the glass protection cover plate is suitable for being placed on the bottom plate, and the front light guide plate is spaced apart and arranged on a side of the glass protection cover plate close to the pressure plate;

[0026] A silicone layer is provided along the edges of the opposite surfaces of the front light guide plate and the glass protective cover plate, and the front light guide plate, the glass protective cover plate and the silicone layer form a glue injection cavity; a glue injection hole is provided on the silicone layer on a side close to the air inlet of the first air flow channel, and an exhaust hole is provided on a side away from the air inlet of the first air flow channel.

[0027] In a second aspect, the present invention further provides a full-bonding method, characterized in that the above-mentioned full-bonding device has the following specific steps: assembling the full-bonding device and the parts to be assembled; placing the full-bonding device horizontally on the workbench with the snap fasteners opened outward; placing the parts to be assembled between the base plate and the pressure plate; adjusting the pressure plate close to the parts to be assembled until a pressure gap exists between the pressure plate and the parts to be assembled; pumping pressurized gas into the air flow channel through an external air pump, and the gas applies pressure toward the front light guide plate in the parts to be assembled through the air outlet ends of the air holes; injecting glue into the glue injection cavity through the glue injection holes; stopping the glue injection until the glue injection cavity is filled with glue; lifting the pressure plate, and rotating the snap fasteners inward to fix the pressure plate on the base plate; after the glue solidifies, rotating the pressure plate outward to open it to remove the assembled parts to be assembled.

[0028] Beneficial effect: During the glue injection process, since the glue is injected from the glue injection hole on the left, the fluidity of the glue is not strong and it will temporarily accumulate on the side of the glue injection cavity close to the glue injection hole. At the same time, under the glue injection pressure of the external glue injection device, the pressure on the left lower surface of the front light guide plate will be relatively large, and the pressure will be smaller towards the right. Through the above-mentioned full-fitting device and packaging steps, during the glue injection process, a pressure plate is placed above the assembly to be assembled, and an external air pump is used to apply pressure to the upper surface of the front light guide plate of the assembly to be assembled through the airflow channel and the air hole. By designing the distance between any two adjacent second airflow channels to gradually increase along the glue injection direction, the pressure on the upper surface of the front light guide plate along the glue injection direction is gradually reduced. That is, the left end close to the air inlet of the first airflow channel is subjected to a large pressure, while the right end is subjected to a small pressure. By adjusting the ventilation pressure of the external air pump, the pressure on the upper and lower surfaces of the same vertical line of the front light guide plate offsets each other, and the front light guide plate always tends to be horizontal to avoid deformation, so that the thickness of the glue on the entire surface is consistent, improving the assembly quality, avoiding the problem of uneven display after the subsequent assembly of the ink screen, and the actual amount of glue used is equal to the theoretical amount, reducing the production and assembly costs. At the same time, the force on the upper surface of the front light guide plate gradually decreases from left to right, and the air pressure on the left side can squeeze the glue directly below, and cooperate with the external glue injection device to accelerate the glue to move evenly toward the exhaust hole, improving the glue injection efficiency.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0041] With the promotion of energy conservation and consumption reduction, green and energy-saving ink screens are increasingly used for outdoor displays. However, in actual applications, since the ink screen itself does not emit light, it needs to be visible in the sun. When there is no light at night, the display content of the ink screen cannot be viewed. It is necessary to add a front light guide plate to the surface of the ink screen to provide a light source. In order to ensure the display consistency of the front light guide plate, it is necessary to fill the front light guide plate and the ink screen with optical glue.

[0042] At present, glue is poured using a perfusion technology, that is, the glue is injected between the front light guide plate and the glass protective cover. However, since the material of the front light guide plate is relatively soft, when the glue is injected from the injection hole, the front light guide plate is usually squeezed and deformed, and the actual amount of glue used is 2-4 times more than the theoretical amount, resulting in an increase in manufacturing costs. At the same time, due to the limitation of the fluidity of the glue, the glue thickness will be uneven during the actual glue pouring process, affecting the uniform display effect.

[0043] In order to solve the above technical problems, the present invention provides a full lamination device.

[0044] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0045] According to an embodiment of the present invention, on the one hand, a full bonding device is provided, which is used to assemble a front light guide plate 51 and a glass protection cover plate 52 in an ink screen. The full bonding device specifically includes: a bottom plate 1 and a pressure plate 2.

[0046] like Figure 1 As shown, the bottom plate 1 is a hard plate that will not deform easily, and provides good support for the assembly of the parts to be assembled 5. The bottom plate 1 is placed horizontally, and a groove for placing the parts to be assembled 5 can be opened on the top of the bottom plate 1, which is convenient for placing the parts to be assembled 5 and limiting the parts to be assembled 5. Four spring guides 3 are arranged at the four corner positions corresponding to the grooves on the upper surface of the bottom plate 1, and the spring guides 3 are fixed vertically. The pressure plate 2 is arranged above the spring guides 3, and the pressure plate 2 is also placed horizontally. The distance between the pressure plate 2 and the bottom plate 1 can be adjusted by adjusting the spring guides 3. A pair of snap fasteners 4 are also provided on the bottom plate 1, which can be rotatably mounted on the bottom plate 1. At least one pair of snap fasteners 4 are provided on the bottom plate 1, and the pair of snap fasteners 4 are symmetrically arranged.

[0047] Specifically, Figure 1 and Figure 4As shown, the pressure plate 2 is provided with a plurality of air holes 21 and air flow channels, and the air flow channels include a plurality of first air flow channels 22 and a plurality of second air flow channels (not shown in the figure), and the first air flow channels 22 and the second air flow channels are cross-arranged so that the air flow channels are arranged in a mesh shape. Specifically, the first air flow channel 22 and the second air flow channel are vertically intersected, and the first air flow channel 22 and the second air flow channel are interconnected, and a plurality of air holes 21 are arranged one by one at the intersection of the first air flow channel 22 and the second air flow channel, and the air inlet end of the air hole 21 is connected to the intersection of the first air flow channel 22 and the second air flow channel, and the air outlet end of the air hole 21 is facing the bottom plate 1. Ensure that the pressure of the gas discharged from each air hole 21 is uniform.

[0048] In this embodiment, if Figure 1 and Figure 4 As shown, the first airflow channel 22 is opened in the pressure plate 2 along the glue injection direction, and the glue injection direction is from left to right. The left end of the first airflow channel 22 is connected to the outside and is the air inlet end. The right end of the first airflow channel 22 is closed and not connected to the outside. The second airflow channel is along the first direction perpendicular to the glue injection channel, that is, Figure 1 In the front-to-back direction, both front and rear ends of the second airflow channel are not connected to the outside.

[0049] In this embodiment, a plurality of airflow channels are arranged at equal intervals along the first direction, and the distance between any two adjacent second airflow channels gradually increases along the glue injection direction, thereby ensuring that the distance between any two adjacent air holes 21 gradually increases along the glue injection direction.

[0050] In this embodiment, if Figure 2 and Figure 3 As shown, the assembly 5 includes: a front light guide plate 51 and a glass protective cover plate 52. The front light guide plate 51 and the glass protective cover plate 52 have the same area. When installing, the front light guide plate 51 is placed above the glass protective cover plate 52. A silicone layer 53 is enclosed along the edges of the opposite surfaces of the front light guide plate 51 and the glass protective cover plate 52. The front light guide plate 51, the glass protective cover plate 52 and the silicone layer 53 enclose a glue injection cavity 54. The silicone layer 53 is provided with a glue injection hole 55 and an exhaust hole 56. The glue injection hole 55 is arranged on the left side of the silicone layer 53, and the exhaust hole 56 is arranged on the right side of the silicone layer 53. A plurality of the glue injection holes 55 and the exhaust holes 56 can be provided along the first direction. The silicone layer 53 is made of soft silicone.

[0051] According to an embodiment of the present invention, on the other hand, a full lamination method is also provided, and the specific steps are as follows:

[0052] When it is necessary to package the assembly 5, first lay the glass protection cover plate 52 flat, place the front light guide plate 51 on the glass protection cover plate 52, align the front light guide plate 51 and the glass protection cover plate 52 up and down, and leave a certain distance between them. Fix a circle of silicone layer 53 between the glass protection cover plate 52 and the front light guide plate 51 to ensure that there is a glue injection cavity 54 between the glass protection cover plate 52, the front light guide plate 51 and the silicone layer 53. A glue injection hole 55 is opened on the left side of the silicone layer 53, and an exhaust hole 56 is opened on the right side of the silicone layer 53, and the assembly of the assembly 5 is completed.

[0053] Assemble the full-fitting device, place the base plate 1 horizontally on the workbench, fix the pressure plate 2 on the upper end of the spring guide rail 3, open the fasteners 4 on both sides, place the assembled part 5 on the base plate 1 and between the two fasteners 4, and at the same time adjust the multiple spring guide rails 3 installed on the pressure plate 2 so that the pressure plate 2 can move up and down until the distance between the pressure plate 2 and the base plate 1 is greater than the required thickness of the part 5 to be assembled after the glue injection is completed, so that there is a pressure gap between the pressure plate 2 and the part 5 to be assembled.

[0054] Place the assembly 5 in the groove on the bottom plate 1, ensure that the exhaust hole 56 faces the same direction as the air inlet of the airflow channel, and pump pressurized gas into the airflow channel through an external air pump. The gas passes through the outlet end of the air hole 21 and applies pressure to the front light guide plate 51 in the assembly 5. At the same time, glue is injected into the injection cavity 54 through the injection hole 55 until the injection cavity 54 is filled with glue or the glue flows out of the exhaust hole 56. Then stop injecting glue. Lift the pressure plate 2 away from the assembly 5, and rotate the two buckles 4 inward to fix the pressure plate 2 on the bottom plate 1.

[0055] After standing for a while to wait for the glue to solidify, the pressure plate 2 is rotated outward to open and remove the assembled parts 5 to be assembled, and the packaging is completed.

[0056] During the glue injection process, since the glue is injected from the glue injection hole 55 on the left, the fluidity of the glue is not strong and it will temporarily accumulate on the side of the glue injection cavity 54 near the glue injection hole 55. At the same time, under the glue injection pressure of the external glue injection device, the pressure on the left lower surface of the front light guide plate 51 will be relatively large, and the pressure will be smaller towards the right end. Through the above-mentioned full-fitting device and full-fitting steps, during the glue injection process, a pressure plate 2 is placed above the assembly 5 to be assembled, and an external air pump is used to apply pressure to the upper surface of the front light guide plate 51 of the assembly 5 through the air flow channel and the air hole 21. By designing the distance between any two adjacent second air flow channels to gradually increase along the glue injection direction, the pressure on the upper surface of the front light guide plate 51 along the glue injection direction is gradually reduced. That is, the left end close to the air inlet of the first air flow channel 22 is subjected to a large pressure, while the right end is subjected to a small pressure. By adjusting the ventilation pressure of the external air pump, the pressures on the upper and lower surfaces of the front light guide plate 51 on the same vertical line offset each other, and the front light guide plate 51 always tends to be horizontal to avoid deformation, so that the thickness of the glue on the entire surface is consistent, thereby improving the assembly quality and avoiding the problem of uneven display after subsequent assembly of the ink screen. The actual amount of glue used is equal to the theoretical amount, thereby reducing the production and assembly costs.

[0057] At the same time, the force exerted on the upper surface of the front light guide plate 51 gradually decreases from left to right, and the air pressure on the left side can squeeze the glue directly below, and cooperate with the external glue injection device to accelerate the glue to move evenly toward the exhaust hole 56, thereby improving the glue injection efficiency.

[0058] In this embodiment, the second airflow channel opened on the pressure plate 2 near the left side of the injection hole 55 is arranged corresponding to the left side of the assembly 5, and the second airflow channel opened on the right side away from the injection hole 55 is arranged corresponding to the right side of the assembly 5. Similarly, the first airflow channels 22 at the front and rear ends opened on the pressure plate 2 need to correspond to the front and rear sides of the assembly 5. A variety of different pressure plates 2 can be preset for assembly parts of different sizes to ensure the quality and efficiency of pressure application.

[0059] And because the air inlet of the air flow channel is arranged on the left side of the pressure plate 2 close to the glue injection hole 55, the air hole 21 on the left side is closer to the external air pump. Due to the fluidity of the gas, the air pressure on the side close to the air inlet in the circulation channel is greater than the pressure on the side away from the air inlet. As a result, the pressure applied by the left air hole 21 on the front light guide plate 51 is greater than the pressure applied by the right air hole 21 on the front light guide plate 51, further accelerating the uniform movement of the glue toward the exhaust hole 56, thereby improving the glue injection efficiency.

[0060] In this embodiment, the buckle 4 is L-shaped. When it is buckled on both sides of the assembly 5, one side wall is attached to the side of the assembly 5, and the other side is attached to the upper surface of the assembly 5, which can limit the position between the front light guide plate 51 and the glass protection cover plate 52 to ensure that the two do not deviate in the left and right directions, and can be used to adjust the thickness of the assembly 5. For different sizes of the assembly 5, a pair of buckles 4 with different sizes and different installation distances can be designed on the bottom plate 1.

[0061] In this embodiment, one pressure plate 2 can correspond to multiple base plates 1, as well as the spring guide rails 3 and the fasteners 4 on the multiple base plates 1. The pressure plate 2 and the spring guide rails 3 are detachably connected, so that the fasteners 4 fix the assembled parts 5 after the injection of glue on the base plate 1. During the process of the glue standing and cooling, the pressure plate 2 is removed from the spring guide rail and moved to the top of another base plate 1 to implement the pressure step, thereby improving the construction efficiency.

[0062] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
