In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0040] According to a first aspect of the present invention, a display screen bonding process is disclosed. The display screen includes a first panel and a second panel. Figure 1 and Figure 2 , the display screen bonding process includes the following steps:

[0041] S100 provides an adhesive tape 100, which includes a base tape 110, a plurality of hot melt adhesive films 120, and a release film 130 having the same number as the hot melt adhesive films 120. The plurality of hot melt adhesive films 120 are sequentially arranged along the length direction of the base tape 110 and bonded to the same side of the base tape 110. The other side of the hot melt adhesive film 120 is bonded to the release film 130. The hot melt adhesive film 120 and the release film 130 are arranged in a one-to-one correspondence.

[0042] S200 causes the base belt 110 to move along a preset track 200 so that the plurality of hot melt adhesive films 120 move to the preset positions 211 in sequence;

[0043] S300 makes the hot melt adhesive film 120 located at the preset position 211 and close to the base tape 110 adhere to the first panel;

[0044] S400: tear off the release film 130, and the other side of the hot melt adhesive film 120 is attached to the second panel.

[0045] Specifically, first, the base band 110 is pulled to move along the preset trajectory 200, and the multiple hot melt adhesive films 120 on the base band 110 move to the preset position 211 in sequence, wherein when the hot melt adhesive film 120 moves to the preset position 211, the side of the hot melt adhesive film 120 located at the preset position 211 close to the base band 110 is separated from the base band 110 and attached to the first panel; then, the release film 130 on the other side of the hot melt adhesive film 120 is torn off, and the other side of the hot melt adhesive film 120 is adhered to the second panel, so that the first panel is bonded and fixed to the second panel. As can be seen from the above, in the present application scheme, the movement of the baseband 110 is utilized so that the multiple hot melt adhesive films 120 on the baseband 110 can be conveniently transported to the preset position 211 in sequence. When the hot melt adhesive film 120 is located at the preset position 211, the hot melt adhesive film 120 is separated from the baseband 110, and the separated hot melt adhesive film 120 is attached to the first panel. In this way, the hot melt adhesive film on the baseband is more convenient to be attached to the first panel, thereby improving the bonding efficiency of the display screen.

[0046] It should be noted that the first panel may be a protective glass or a touch panel, and the second panel may be a display module, or the second panel may be a protective glass or a touch panel, and the first panel may be a display module.

[0047] In some embodiments, along the running direction of the base tape 110, the preset track 200 includes a first section 210 and a second section 220, the first section 210 is arranged along a straight line direction, for example, extending horizontally, the hot melt adhesive film 120 is located on the upper side of the base tape 110, and the release film 130 is located directly above the hot melt adhesive film 120; the second section 220 is bent relative to the first section 210 toward the back direction of the base tape 110, that is, the second section 220 is extended downward; wherein the preset position 211 is located at the end of the first section 210 close to the second section 220. Specifically, during the movement of the base tape 110 along the preset track 200, during the movement of the base tape 110 from the first section 210 to the second section 220, that is, the base tape 110 moves from left to right and turns to move downward; wherein, when the base tape 110 is turning, the hot melt adhesive film 120 and the base tape 110 are separated from each other.

[0048] In order to achieve the reversal of the trajectory of the base belt 110, a guide member is generally arranged at the reversing position of the preset trajectory 200. The guide member is a roller or a sheet body with an arc-shaped guide surface. The back side of the base belt 110 is wrapped around the arc-shaped surface of the guide member. In this way, when the base belt 110 moves around the arc-shaped surface of the guide member, the base belt 110 performs a reversing motion, thereby facilitating the separation of the hot melt adhesive film 120 from the base belt 110.

[0049] It is understandable that the first section 210 is arranged substantially along a straight line direction, so that when the base tape 110 moves along the first section 210 , the hot melt adhesive film 120 is stably adhered to the base tape 110 and will not be separated from the base tape 110 .

[0050] Alternatively, a scraper is provided on the preset track 200 , and the scraper is substantially consistent with the track of the base tape 110 , so that when the base tape 110 moves along the preset track 200 , the scraper separates the hot melt adhesive film 120 from the base tape 110 .

[0051] In some embodiments, before step S100, there are the following steps: referring to Figures 1 to 3 , S10 prepares a strip-shaped base tape 110, a strip-shaped hot melt adhesive film 120 and a strip-shaped release film 130, wherein the base tape 110 is attached to one side of the hot melt adhesive film 120, and the release film 130 is attached to the other side of the base tape 110; S20 cuts the release film 130 along the width direction of the release film 130 to cut the release film 130 into multiple sections; and, cuts the hot melt adhesive film 120 along the width direction of the hot melt adhesive film 120 to cut the hot melt adhesive film 120 into multiple sections, wherein the hot melt adhesive film 120 and the release film 130 are arranged one by one, and then, rolls the adhesive 100 obtained above, i.e., winds it on the unwinding member 300. Alternatively, after cutting, the adhesive 100 directly moves along the preset track 200, so as to perform the bonding of the first panel and the hot melt adhesive film 120.

[0052] In some embodiments, in step S100, the adhesive 100 is wound around the rotatable unwinding member 300, and in step S200, the rewinding member 400 is driven to rotate so that the base tape 110 moves along the preset track 200 and the base tape 110 is wound around the circumference of the rewinding member 400. Specifically, the laminating device is provided with an unwinding member 300 and a rewinding member 400, and a motor is used to drive the rewinding member 400 to rotate. During the rotation of the rewinding member 400, the rewinding member 400 pulls the base tape 110 to move along the preset track 200 and the base tape 110 is wound around the circumference of the rewinding member 400. At this time, the unwinding member 300 is also in a rotating state, and the unwinding member 300 is in a material unloading state. As can be seen from the above, by setting the winding member 400, the base band 110 can be moved along the preset trajectory 200 and quickly retracted. Moreover, the unwinding member 300 cooperates with the winding member 400 to make the base band 110 move along the preset trajectory 200 and separate the hot melt adhesive film 120 from the base band 110.

[0053] It should be noted that in the present application, the hot melt adhesive film has low adhesive force, and the adhesive 100 in the present application can be provided in a roll. In the conventional technology, the adhesive film used between the first panel and the second panel is OCA, which has a large adhesive force. If OCA is used in the present application, the adhesive 100 in the present application cannot be provided in a roll.

[0054] In some embodiments, the hot melt adhesive film 120 is one of TOCA and COF, so that the cut adhesive film 100 can be set in a roll.

[0055] In some embodiments, two rollers may be used to move the base belt 110, and the gap between the two rollers allows the base belt 110 to pass through. A motor is used to drive one roller to rotate, and the two rollers work together to pull the base belt 110 to move along the preset track 200.

[0056] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 , step S300 includes the following steps: S310 placing the first panel at the first bonding position 230, wherein one end of the first bonding position 230 is connected to the end of the preset position 211 close to the second section 220, so that the detached hot melt adhesive film 120 moves to the first bonding position 230; S320 pressing the release film 130, so that the side of the hot melt adhesive film 120 away from the release film 130 is attached to the first panel. Specifically, when the base tape 110 corresponding to the hot melt adhesive film 120 moves along the trajectory of the second section 220, the corresponding hot melt adhesive film 120 separates from the base tape 110 and continues to move along the trajectory direction of the first section 210, that is, continues to move to the right. In this way, the separated hot melt adhesive film 120 moves to the right to the first bonding position 230, that is, the upper side of the first panel; thereafter, the scraper or pressure roller above the release film 130 presses the release film 130 downward, so that the hot melt adhesive film 120 corresponding to the release film 130 is attached to the top of the first panel. It should be noted that before the hot melt adhesive film 120 is in a melted state, the hot melt adhesive film 120 has no adhesive force with the first panel, so the hot melt adhesive film 120 can completely slide to the top of the first panel, and the edge of the hot melt adhesive film 120 is aligned with the opposite surface of the first panel. Alternatively, the right end of the hot melt adhesive film 120 has just separated from the base tape 110, and the right end of the hot melt adhesive film 120 is aligned with the right end of the opposing surface of the first panel. Thereafter, the hot melt adhesive film 120 moves to the right synchronously with the first panel, and synchronously, the scraper or pressure roller presses the corresponding hot melt adhesive film 120.

[0057] Instead of the above step S300, refer to Figure 1 and Figure 5 , step S300 includes the following steps: S310 using a first adsorbent to absorb the release film 130; S320 moving the adsorbent to a second attachment position, and the side of the hot melt adhesive film 120 away from the release film 130 is attached to the first panel. Specifically, the film attachment mechanism of the attachment device adopts an adsorption method to smoothly pick up the hot melt adhesive film 120 and automatically attach the hot melt adhesive film 120 smoothly to the first panel, so that the display screen attachment efficiency is high. Alternatively, the hot melt adhesive film 120 can also be picked up by a robot, manual or other methods.

[0058] In some embodiments, the release film 130 can be detached by sucking the release film 130 with a suction cup to separate the release film 130 from the hot melt adhesive film 120. The release film 130 can also be detached manually or by a robot.

[0059] In some embodiments, during step S400 , after the release film 130 is separated from the hot melt adhesive film 120 , another suction cup structure is used to suck the first panel, and the first panel is attached to the second panel, so that the side of the hot melt adhesive film 120 away from the first panel is attached to the second panel.

[0060] In some embodiments, reference Figure 1 and Figure 6 , the display screen bonding process also includes the following steps: S500 vacuum pressing the first panel and / or the second panel: wherein step S500 includes the following steps: S510 prepares a vacuum environment; S520 makes the pressing plate stick to the first panel and / or the second panel under a vacuum environment; S530 breaks the vacuum; S540, the pressing plate is separated from the first panel and / or the second panel. Specifically, a hot pressing device is provided, and the bonded display screen is placed in the hot pressing device. Before the pressing plate of the hot pressing device presses the display screen, the working environment of the hot pressing device is made into a vacuum state. Thereafter, the pressing plate is made to stick to the display screen, and the pressing plate heats the display screen, so that the hot melt adhesive film 120 is in a molten state. In this way, the molten hot melt adhesive film 120 can flow in the gap between the first panel and the second panel, so that the hot melt adhesive film 120 is evenly filled in the gap between the first panel and the second panel, thereby ensuring that the second panel is tightly bonded to the second panel.

[0061] It is understandable that in a vacuum environment, the pressing plate is pressed against the side of the display screen, so as to avoid the presence of many bubbles between the first panel and the second panel when the pressing plate is pressed; at the same time, before the pressing plate is separated from the first panel, the closed door of the hot pressing device is opened, and the working environment of the hot pressing device is no longer a vacuum environment. At this time, since the pressing plate has a pressing effect on the display screen, it can prevent external air from entering between the two panels to form bubbles, thereby improving the tightness of the panel fit. In addition, the pressing plate is a frame-like structure, which is convenient for sealing the edges of the panels.

[0062] It should be noted that the hot melt adhesive film 120 can be pressed by cold pressing or hot pressing, so as to heat the hot melt adhesive film 120 and make the hot melt adhesive film 120 in a molten state.

[0063] Further, in step S530, after the pressing plate has finished heating the display screen and the pressing plate is kept in the pressed state, the closed door of the hot pressing device is opened, and external air enters the working environment of the hot pressing device, so as to prevent a small amount of air from entering between the first panel and the second panel during the hot pressing process of the display screen and forming bubbles between the two panels. Alternatively, when the pressing plate is heating the display screen and the pressing plate is kept in the pressed state, the closed door of the hot pressing device is opened, and external air enters the working environment of the hot pressing device, at this time, the hot melt adhesive film 120 has better fluidity, and the hot melt adhesive film 120 in the molten state can better fill the gap between the first panel and the second panel.

[0064] In addition, a plurality of heat-pressing chambers may be provided in the heat-pressing equipment to heat-press a plurality of bonded panels at the same time, or a plurality of panels may be pressed in one heat-pressing chamber.

[0065] In some embodiments, reference Figure 1 , after step S500, the following steps are also included: S600 degassing the first panel and the second panel; curing the bonding area of ​​the hot melt adhesive film 120. Specifically, the degassing process in step S500 requires pressurizing the first panel and the second panel to squeeze out the bubbles between the two, so that the first panel and the second panel are closely bonded to optimize the bonding effect. The above-mentioned degassing process can be carried out in a degassing device, and the process can also be performed in a vacuum environment, using pressure and temperature to remove bubbles generated in the bonding adhesive during the bonding process. The curing in S600 can be achieved by thermal curing or UV curing, so that the bonding adhesive undergoes a cross-linking reaction to achieve fixation between the first panel and the second panel; the temperature of thermal curing is greater than 60° to ensure the bonding strength and stability between the first panel and the second panel.

[0066] According to a second aspect of the present invention, a display screen is disclosed, which is made by the above-mentioned display screen bonding process. Figure 1 and Figure 2 In the present application, the unwinding member 300 is unwinding and the rewinding member 400 is rewinding, so that the adhesive 100 moves along the preset track 200. During the movement of the adhesive 100, multiple hot melt adhesive films 120 move to the preset positions 211 in sequence, and when the hot melt adhesive film 120 is at the preset position 211, one end of the hot melt adhesive film 120 is separated from the base tape 110. At this time, the laminating device can easily absorb the hot melt adhesive film 120 and paste it on the back of the second panel, thereby improving the laminating efficiency of the display screen.

[0067] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
