[0038] Please refer to Figures 1 to 3The embodiment of the application provides a sticking device for an LCD glass substrate easy-to-tear sticker, which comprises a mounting plate 1, a sticker mounting frame 2, a plurality of guide wheels 3, a first waste tape winding part 4, a second waste tape winding part 5, a downward sticking part 6, a conveying belt 7 and a sensor 8. The mounting plate 1 is fixed on a rack. The sticker mounting frame 2 is rotatably arranged on the mounting plate 1, and a sticker tape 10 in a roll is arranged on the sticker mounting frame 2. The guide wheels 3 are rotatably arranged on the mounting plate 1, and the sticker tape 10 is wound on the guide wheels 3. The first waste tape winding part 4 is rotatably arranged on the mounting plate 1, and the first waste tape winding part 4 winds a protection tape 101 in the sticker tape 10. The second waste tape winding part 5 is rotatably arranged on the mounting plate 1, and the second waste tape winding part 5 winds an adhesive tape 102 in the sticker tape 10. The downward sticking part 6 is arranged above the adhesive tape 102. The conveying belt 7 is arranged below the mounting plate 1, and a glass plate 11 to be stuck with an easy-to-tear sticker 103 is conveyed on the conveying belt 7. The sensor 8 is arranged on the conveying belt below the downward sticking part 6, and the sensor 8 is electrically connected with the downward sticking part 6, the first waste tape winding part 4 and the second waste tape winding part 5. The sensor 8 monitors the position of the glass plate 11. Specifically, the sensor 8 can be a photoelectric sensor 8.

[0039] The full-automatic sticking device provided by the embodiment only needs to place the glass plate 11 to be stuck with the easy-to-tear sticker 103 on the conveying belt 7 when sticking. When the sensor 8 senses that the glass plate 11 moves to a sticking position, the sensor 8 controls the downward sticking part 6 to press the adhesive tape 102, so that the easy-to-tear sticker 103 attached to the bottom surface of the adhesive tape 102 is stuck on the surface of the glass plate 11. When the easy-to-tear sticker 103 is completely stuck on the surface of the glass plate 11, the downward sticking part 6 immediately rises. In this process, the first waste tape winding part 4 and the second waste tape winding part 5 rotate synchronously, the rotating amount of the first waste tape winding part 4 and the second waste tape winding part 5 is the center distance of two adjacent easy-to-tear stickers 103 on the adhesive tape 102, and the rotating speed is consistent with the conveying speed of the conveying belt 7, so as to cooperate with the sticking action. After the first waste tape winding part 4 and the second waste tape winding part 5 rotate once, one sticking action is completed. After the conveying belt 7 detects the next glass plate 11, the next sticking action is performed. The first waste tape winding part 4 and the second waste tape winding part 5 are used to separate the protection tape 101 and the adhesive tape 102 on the sticker tape 10, so that the easy-to-tear sticker 103 protected by the protection tape 101 is exposed, so as to facilitate the attachment of the easy-to-tear sticker 103 to the glass plate 11.

[0040] In one embodiment, the downward sticking part 6 comprises a downward plate 61 and a downward cylinder 62. One end of the downward plate 61 is hinged to the mounting plate 1. The cylinder body of the downward cylinder 62 is hinged to the mounting plate 1, and the piston rod of the downward cylinder 62 is hinged to the other end of the downward plate 61. The downward cylinder 62 is electrically connected with the sensor 8.

[0041] As Figure 3As shown, when the sensor 8 detects that the glass plate 11 moves to the adhering position, at this time, the piston rod of the down-pressing cylinder 62 is elongated, so that the down-pressing plate 61 rotates clockwise around its hinge point and presses down, and then presses down the adhering tape 102 below the movable end of the down-pressing plate 61 to the surface of the glass plate 11 below. Since the easy-to-tear tape 103 is arranged on the lower surface of the adhering tape 102 (the adhesive side of the easy-to-tear tape 103 is arranged downward), the easy-to-tear tape 103 can be adhered to the glass plate 11 by the pressing force provided by the down-pressing plate 61 in cooperation with the movement of the conveying belt 7 and the second waste tape winding part 5.

[0042] In an embodiment, the down-pressing adhering part 6 further comprises a down-pressing pad 63 made of elastic material, which is arranged on the lower surface of the movable end of the down-pressing plate 61. By arranging the down-pressing pad 63 made of elastic material, when the easy-to-tear tape 103 is pressed onto the glass plate 11 so as to be adhered to the surface of the glass plate 11, the down-pressing pad 63 can transmit the pressure and also has a buffering effect, so that the pressure provided by the down-pressing plate 61 can be uniformly applied to the easy-to-tear tape 103 and the glass plate 11, avoiding stress concentration and damage to the glass plate 11 below.

[0043] Specifically, the down-pressing pad 63 is a rubber block. The down-pressing pad 63 made of rubber material has good elasticity and wear resistance, which can not only have a buffering effect, but also can ensure the service life of the down-pressing pad 63.

[0044] In an embodiment, the first waste tape winding part 4 comprises a first waste tape winding wheel and a first motor, the first waste tape winding wheel is rotatably arranged on the mounting plate 1, and the motor shaft of the first motor is connected with the first waste tape winding wheel. The second waste tape winding part 5 comprises a second waste tape winding wheel and a second motor, the second waste tape winding wheel is rotatably arranged on the mounting plate 1, and the motor shaft of the second motor is connected with the second waste tape winding wheel. The first motor and the second motor are electrically connected with the sensor 8 and synchronously rotate. The sticker tape 10 comprises a protective tape 101, an adhering tape 102 and an easy-to-tear tape 103, the easy-to-tear tape 103 is attached to the adhering tape 102, and the adhering surface of the easy-to-tear tape 103 is covered with the protective tape 101. The first waste tape winding part 4 separates the protective tape 101 from the adhering tape 102, so that the adhering surface of the easy-to-tear tape 103 is exposed, facilitating the adhesion of the easy-to-tear tape 103.

[0045] In one embodiment, the tensioning device 9 comprises a tensioning plate 91, a tensioning wheel 92 and an elastic member 93. One end of the tensioning plate 91 is hinged to the mounting plate 1, the tensioning wheel 92 is rotatably arranged on the tensioning plate 91, one end of the elastic member 93 is fixed to the mounting plate 1, and the other end of the elastic member 93 is connected to the tensioning plate 91. The sticker tape 10 is wound on the tensioning wheel 92. The upward elastic force of the elastic member 93 acts on the tensioning plate 91, so that the tensioning plate 91 has a tendency to rotate counterclockwise upward, and the tensioning wheel 92 can pull the sticker tape 10 on it upward.

[0046] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
