[0074] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0075] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0076] It should be noted that the directional words such as "up, down, left, right" etc. mentioned below are defined based on the drawings in the specification.

[0077] The core of the present invention is to provide a glass substrate bonding process, which can leave no gap between the chamfered corners of the film material 02 and the glass 01, thereby improving the bonding yield. Another core of the present invention is to provide a glass substrate bonding device including the above-mentioned glass substrate bonding process, which can improve the bonding accuracy and stability of the equipment, thereby improving the yield.

[0078] Please refer to Figure 1 and Figure 2 , a glass substrate bonding process includes:

[0079] Step S1, placing the glass 01 directly below the film 02 and aligning the first ends of the glass 01 and the film 02;

[0080] Step S2, hot-pressing the second end of the film material 02 on the front surface of the glass 01 by the positive pressure head 41, and maintaining the positive pressure state;

[0081] Step S3, bend the second end of the film material 02 to be close to the side of the glass 01 by the bending suction plate 21, so that the side pressing head 51 hot presses the second end of the film material 02 to the side of the glass 01 and maintains the side pressing state;

[0082] Step S4 , bend the second end of the film material 02 to be close to the back side of the glass 01 by using the bending suction plate 21 , and use the back pressure head 61 to hot-press the second end of the film material 02 to the back side of the glass 01 .

[0083] Place the glass 01 directly below the film material 02 and align the first ends of the glass 01 and the film material 02. First align the glass 01 and the film material 02 to prepare for the bonding of the film material 02 to provide a precise bonding position and improve the accuracy of bonding the film material 02. After aligning one end of the glass 01 with the first end of the film material 02, hot press the second end of the film material 02 to the front of the glass 01 through the positive pressure head 41 to achieve bonding of the film material 02 to the front of the glass 01. After completing the front bonding, keep the positive pressure head 41 in a positive pressure state, that is, press the positive pressure head 41 on the front of the glass 01. Then, bend the second end of the film material 02 through the bending suction plate 21 to fit the side of the glass 01. The rotation of the bending suction plate 21 drives the second end of the film material 02 to rotate synchronously, so that the second end of the film material 02 is bonded to the 01, and then the second end of the film material 02 is bent by the bending suction plate 21 to be close to the back of the glass 01. The rotation of the bending suction plate 21 drives the second end of the film material 02 to rotate synchronously, so that the second end of the film material 02 is close to the back of the glass 01. After the second end of the film material 02 is close to the back of the glass 01, the back pressure head 61 is used to hot-press the second end of the film material 02 to the back of the glass 01, so as to achieve the bonding of the film material 02 to the back of the glass 01.

[0084] The pressing head bonding pressure adopts a multi-stage control method to protect the glass 01 from cracks and deformation after bonding.

[0085] In the bonding process of the glass substrates arranged in the above manner, the bonding sequence of the glass 01 and the film material 02 is front bonding - film material 02 bending - side bonding - film material 02 bending - back bonding. The face-to-face pressing method using a hot flat press head can ensure the distance accuracy and stability after the front and back sides are bonded. The film material 02 can be tightened by bending, so that it can fit tightly against the side chamfer of the glass 01 without leaving any gaps, thereby greatly improving the yield rate of the finished bonding products.

[0086] In the above embodiment, the process of placing the glass 01 directly below the film 02 and aligning the first ends of the glass 01 and the film 02 includes:

[0087] The auxiliary suction plate 11 absorbs the first end of the film material 02, and the bending suction plate 21 absorbs the second end of the film material 02, so that the film material 02 is absorbed and flattened;

[0088] Place the glass 01 on the support plate 31 below the auxiliary suction plate 11, with the front side of the glass 01 facing upwards;

[0089] The position of the glass 01 relative to the film material 02 is acquired through the photographing component 32 , and the acquired image information is sent to the controller 7 . The controller 7 controls the adjustment component 33 to operate to adjust the position of the glass 01 so that the first end of the glass 01 is aligned with the first end of the film material 02 .

[0090] It should be noted that before bonding the film material 02 to the glass 01, the first end of the film material 02 is first adsorbed by the auxiliary suction plate 11, and the second end of the film material 02 is adsorbed by the bending suction plate 21. The film material 02 is adsorbed and flattened under the action of the auxiliary suction plate 11 and the bending suction plate 21. At the same time, the glass 01 is placed on the support plate 31 with the front of the glass 01 facing up. Then, the controller 7 controls the adjustment component 33 to drive the support plate 31 and the glass 01 on the support plate 31 to move synchronously. At the same time, the position of the glass 01 relative to the film material 02 is obtained by the camera component 32, and the obtained image information is sent to the controller 7. The controller 7 controls the adjustment component 33 to adjust the position of the glass 01 so that the first end of the glass 01 is aligned with the first end of the film material 02, so as to prepare for the bonding of the film material 02 to the glass 01.

[0091] Among them, the bonding alignment uses the same group of cameras to simultaneously photograph the marking points of glass 01 and film material 02 to improve the photography accuracy and achieve high-precision alignment.

[0092] In the above situation, the process of hot pressing the second end of the film material 02 to the front surface of the glass 01 by the positive pressure head 41 and maintaining the positive pressure state includes:

[0093] The controller 7 controls the first driving assembly 62 to operate, so as to drive the back pressure head 61 to move upward, until the back pressure head 61 abuts against the back side of the glass 01;

[0094] The controller 7 controls the second heating component to heat the positive pressure head 41. When the hot pressing temperature of the positive pressure head 41 reaches the requirement, the controller 7 controls the second driving component 42 to drive the positive pressure head 41 to move downward, so that the positive pressure head 41 hot presses the second end of the film material 02 on the front of the glass 01.

[0095] After the positive pressure film 02 is applied to the front surface of the glass 01 , the controller 7 controls the positive pressure head 41 and the back pressure head 61 to maintain the positions in the positive pressure state.

[0096] It can be understood that when the film material 02 and the glass 01 are aligned, the controller 7 controls the first driving component 62 to operate, drives the back pressure head 61 to move upward, so that the back pressure head 61 abuts against the back of the glass 01, and then controls the second heating component to heat the positive pressure head 41 to the hot pressing temperature, and then controls the second driving component 42 to operate, drives the positive pressure head 41 to hot press the film material 02 on the front of the glass 01, and provides support for the hot pressing of the front of the glass 01 through the back pressure head 61. After the positive pressure head 41 hot presses the film material 02 on the front of the glass 01, the positive pressure head 41 and the back pressure head 61 are kept in the current position, that is, the positive pressure head 41 is kept pressed on the front of the glass 01, and the back pressure head 61 is kept pressed on the back of the glass 01.

[0097] Furthermore, the second end of the film material 02 is bent by the bending suction plate 21 to be close to the side of the glass 01, so that the side pressure head 51 heat presses the second end of the film material 02 to the side of the glass 01, and the process of maintaining the side pressure state includes:

[0098] The controller 7 controls the third driving assembly 22 to operate, so as to drive the bending suction plate 21 to rotate so as to bend the second end of the film material 02 to the side of the glass 01;

[0099] The controller 7 controls the third heating component to heat the side pressing head 51. When the hot pressing temperature of the side pressing head 51 reaches the requirement, the controller 7 controls the fourth driving component 52 to drive the side pressing head 51 to move toward the side of the glass 01, so that the side pressing head 51 hot presses the second end of the film material 02 to the side of the glass 01;

[0100] After the film material 02 is side-pressed on the side of the glass 01 , the controller 7 controls the side-pressing head 51 to maintain the position in the side-pressing state.

[0101] It should be noted that, after the film material 02 completes the positive pressure on the glass 01, the controller 7 controls the third driving component 22 to operate, drives the bending suction plate 21 to rotate, drives the second end of the film material 02 to rotate synchronously, and makes the second end of the film material 02 fit the side of the glass 01. Then, the third heating component is controlled to heat the side pressing head 51 to the hot pressing temperature, and then the fourth driving component 52 is controlled to operate, drives the side pressing head 51 to hot press the film material 02 on the side of the glass 01, and provides support for the hot pressing of the side of the glass 01 through the positive pressure head 41 and the back pressure head 61. After the side pressure head 51 hot presses the film material 02 on the side of the glass 01, the positive pressure head 41, the back pressure head 61 and the pressure measuring head are kept in the current position, that is, the positive pressure head 41 is kept pressed on the front of the glass 01, the back pressure head 61 is kept pressed on the back of the glass 01, and the pressure measuring head is kept pressed on the side of the glass 01.

[0102] In the above embodiment, the process of bending the second end of the film material 02 to be close to the back of the glass 01 by the bending suction plate 21 and hot pressing the second end of the film material 02 to the back of the glass 01 by the back pressure head 61 includes:

[0103] The controller 7 controls the first driving assembly 62 to operate, so as to drive the back pressure head 61 to move downward, thereby providing space for the bending suction plate 21 to rotate;

[0104] The controller 7 controls the third driving assembly 22 to operate, so as to drive the bending suction plate 21 to rotate so as to bend the second end of the film material 02 on the back side of the glass 01;

[0105] The controller 7 controls the first heating component to heat the back pressure head 61. When the hot pressing temperature of the back pressure head 61 reaches the requirement, the controller 7 controls the first driving component 62 to operate to drive the back pressure head 61 to move upward so that the back pressure head 61 hot presses the second end of the film material 02 on the back side of the glass 01.

[0106] It can be understood that after the film material 02 completes the lateral pressure on the glass 01, the controller 7 controls the first driving component 62 to operate, driving the back pressure head 61 to move downward, providing space for the rotation of the bending suction plate 21, and avoiding the interference between the rotation of the bending suction plate 21 and the back pressure head 61. After the back pressure head 61 makes room for the bending suction plate 21 to rotate, the controller 7 controls the third driving component 22 to operate, driving the bending suction plate 21 to rotate, driving the second end of the film material 02 to rotate synchronously, so that the second end of the film material 02 is attached to the back of the glass 01, and then After controlling the first heating component to heat the back pressure head 61 to the hot pressing temperature, the first driving component 62 is controlled to operate, driving the back pressure head 61 to hot press the film material 02 on the back side of the glass 01, and providing support for the hot pressing of the back side of the glass 01 through the positive pressure head 41 and the pressure measuring head. After the back pressure head 61 hot presses the film material 02 on the back side of the glass 01, the first driving component 62, the second driving component 42, the third driving component 22 and the fourth driving component 52 are controlled to operate so that the back pressure head 61, the positive pressure head 41, the bending suction plate 21 and the side pressure head 51 are withdrawn.

[0107] During bonding, the pressure head can achieve rapid heating and cooling through the heating component to protect the film material 02.

[0108] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , a glass substrate bonding device, applied to the above-mentioned glass substrate bonding process, the bonding device comprises:

[0115] A controller 7 is used to control the adsorption component 1, the bending component 2, the alignment component 3, the front heat pressing component 4, the side heat pressing component 5 and the back heat pressing component 6.

[0116] It should be noted that the operation states of the adsorption component 1, the bending component 2, the alignment component 3, the front hot pressing component 4, the side hot pressing component 5 and the back hot pressing component 6 are controlled by the controller 7. The adsorption component 1 is controlled by the controller 7 to adsorb the first end of the film material 02, the bending component 2 is controlled to adsorb the second end of the film material 02, and the rotation of the second end of the film material 02 can be controlled at the same time, the alignment component 3 is controlled to adjust the position of the glass 01 and the film material 02 to achieve accurate alignment of the glass 01 and the film material 02, the front hot pressing component 4 is controlled to hot press the second end of the film material 02 on the front of the glass 01, the side hot pressing component 5 is controlled to hot press the second end of the film material 02 on the side of the glass 01, and the back hot pressing component 6 is controlled to hot press the second end of the film material 02 on the back of the glass 01, thereby completing the effective bonding of the film material 02 and the glass 01.

[0122] It can be understood that the horizontal adjustment component 43 is controlled by the controller 7 to adjust the horizontality of the positive pressure head 41, and then the second heating component is controlled to operate to heat the positive pressure head 41. After the positive pressure head 41 is heated to the hot pressing temperature, the second driving component 42 is controlled to operate to drive the positive pressure head 41 to move downward until the positive pressure head 41 presses the film material 02 to the front of the glass 01.

[0128] It should be noted that the third heating component is controlled by the controller 7 to heat the side pressing head 51. After the side pressing head 51 is heated to the hot pressing temperature, the fourth driving component 52 is controlled to drive the side pressing head 51 to move to the right until the side pressing head 51 presses the film material 02 positively to the side of the glass 01.

[0129] The end surface of the side pressure head 51 that contacts the membrane material 02 is provided with a thin high-temperature resistant silicone.

[0130] Please refer to Figure 6 , the back heat pressing assembly 6 comprises:

[0131] A first heating component for controlling the hot pressing temperature of the back pressure head 61;

[0132] A first driving assembly 62 for driving the back pressure head 61 to move;

[0133] The first heating component and the first driving component 62 are both connected to the controller 7 by signals.

[0134] It can be understood that the first heating component is controlled by the controller 7 to heat the back pressure head 61. After the back pressure head 61 is heated to the hot pressing temperature, the first driving component 62 is controlled to drive the back pressure head 61 to move upward until the back pressure head 61 presses the film material 02 to the back of the glass 01.

[0135] Among them, the end surface of the back pressure head 61 that contacts the membrane material 02 is provided with a silicone tape assembly 63, and the silicone tape assembly 63 includes a disposable silicone tape, and also includes a discharge wheel for outputting the silicone tape, and a collection wheel for recycling the waste silicone tape after use. The collection wheel and the discharge wheel are both driven by a motor, and the motor is controlled by the controller 7. When the back pressure head 61 performs hot pressing or supports the glass 01, the first drive assembly 62 is controlled by the controller 7 to operate, driving the back pressure head 61 to move upward, so that the back pressure head 61 first contacts the silicone tape, and then drives the silicone tape to contact the back side of the glass 01.

[0136] Please refer to Figure 7 , the bending component 2 comprises:

[0137] A suction plate assembly for adsorbing the second end of the film material 02;

[0138] A third driving assembly 22 for driving the suction plate assembly to move and rotate;

[0139] The suction plate assembly and the third driving assembly 22 are both connected to the controller 7 via signals.

[0140] It should be noted that the third driving assembly 22 is controlled by the controller 7 to operate, drive the suction plate assembly to move and rotate, and drive the second end of the film material 02 to rotate and move.

[0141] When the bonding device completes the bonding of the film material 02 to the glass 01, the controller 7 controls the first drive component 62 to operate, so that the back pressure head 61 moves downward; controls the second drive component 42 to operate, so that the positive pressure head 41 moves upward; controls the third drive component 22 to operate, so that the bending suction plate 21 is reset; controls the fourth drive component 52 to operate, so that the side pressure head 51 moves to the left, in preparation for the next bonding of the bonding device.

[0142] In summary, the glass substrate bonding process provided by the present invention adopts a face-to-face pressing method using a hot flat press head, which can ensure the distance accuracy and stability after the front and back surfaces are bonded, eliminate the panel chamfer gap, and improve the finished product yield.
