[0002] In the manufacturing process of large display screens (usually over 60 inches, and some are 98 inches and 110 inches), there is a process of bonding the TP conductive film to the glass cover. However, in practice, this process is prone to bubbles, dirt and other undesirable phenomena. Moreover, in subsequent processes, the TP film is also prone to contamination due to various reasons. At this time, the TP film needs to be separated from the glass cover so that the glass cover can be reused, and the TP film can only be scrapped.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0037] See also Figures 1 to 10 The embodiment of the present invention provides a TP film laser cutting and separation device, including a frame 10, on which there is provided,

[0038] A transmission mechanism 20, wherein the transmission mechanism 20 is provided with a loading platform 21 for carrying the glass cover plate 70, and the transmission mechanism 20 transmits the loading platform 21 in a lateral direction;

[0039] A laser cutting device 30, used for cutting the TP film 71 on the glass cover plate 70 into multiple pieces;

[0040] A fixing device 40, used to fix the glass cover plate 70 on the loading platform 21;

[0041] A heating device 50, used for heating the glass cover plate 70 and the TP film 71;

[0042] The film tearing mechanism 60 includes a plurality of gripper devices 61 arranged side by side. The plurality of gripper devices 61 respectively tear off the plurality of TP films 71 cut by the laser cutting device 30 on the glass cover plate 70 .

[0043] The TP film 71 is cut into small pieces by using a laser cutting device 30. When tearing off the film, it is very easy to tear off a single piece of the TP film 71. In addition, during the film tearing process, the heating device 50 is used to heat the adhesive between the TP film 71 and the glass cover plate 70, thereby reducing their adhesion strength and making the film tearing smoother. Compared with the prior art, the present application scheme is faster and saves power.

[0044] Furthermore, a first support frame 11 extending in the transverse direction is provided above both sides of the transmission mechanism 20, and a first driving slide rail 12 extending in the transverse direction is provided on each of the two first support frames 11. A movable support frame 13 extending in the longitudinal direction is provided between the two first driving slide rails 12, and a second driving slide rail 14 is provided on the movable support frame 13. A connecting plate 15 is provided on the second driving slide rail 14, and a laser cutting device 30 is arranged on the connecting plate 15 and moves with the connecting plate 15. The movable support frame 13 moves horizontally on the first support frame 11, and the laser cutting device 30 moves longitudinally on the second driving slide rail 14, so that the laser cutting device 30 can be controlled to move in both the vertical and horizontal directions. In actual work, the laser cutting device 30 moves horizontally for multiple times, thereby cutting the TP film 71 into multiple parts. Here, this embodiment is driven by a motor in conjunction with a belt (not shown in the figure). In some other embodiments, the laser cutting device 30 can also be driven by a linear module or the like, as long as it can be driven to move in the vertical and horizontal directions. It is not limited to this. In actual work, the laser cutting device 30 cuts the TP film 71 into multiple sections horizontally.

[0045] Further, the surface of the front end of the loading platform 21 is provided with a stopper strip 22 for stopping the front side of the glass cover plate 70, the stopper strip 22 extends longitudinally, the fixing device 40 includes a fixing frame 41, a pressing plate 42 for pressing the rear end of the glass cover plate 70 on the loading platform 21, and a first driving mechanism 43 for driving the pressing plate 42 to move up and down, the fixing frame 41 is longitudinally mounted on the frame 10, the first driving mechanism 43 is arranged on the fixing frame 41, and the pressing plate 42 extends longitudinally and is connected to the first driving mechanism 43. In this embodiment, since there is no need for particularly precise size control when tearing the TP film 71, there is no need to use a vacuum suction hole, and only the stopper strip 22 and the pressing plate 42 are needed to meet the requirements of fixing the glass cover plate 70, the structure is simple, easy to manufacture and assemble, and the stopping method of the stopper strip 22 is safer, and it is not easy to cause the glass cover plate 70 to be dragged away from the loading platform 21 in the horizontal direction due to the failure of the pressing plate 42 to press (or vacuum suction is used, but the vacuum suction fails to suck), which is easy to cause accidents.

[0046] Furthermore, an opening 23 of a preset size and extending vertically is provided in the middle of the loading platform 21. The heating device 50 is located below the loading platform 21. The heating device 50 includes a third driving rail 51 extending laterally, a first sliding seat 52, a first heating roller 53, and a second driving mechanism 54 for driving the first heating roller 53 to move up and down. The first sliding seat 52 is arranged on the third driving rail 51, the second driving mechanism 54 is arranged on the first sliding seat 52 and moves with the first sliding seat 52, and the first heating roller 53 extends longitudinally and is connected to the second driving mechanism 54. When the TP film 71 is torn, the first heating roller 53 is pressed upward against the glass cover plate 70 located on the loading platform 21 through the opening 23, and the first heating roller 53 is moved to the place where the TP film 71 is torn, so that the glass cover plate 70 can be heated immediately, and the heat is transferred to the adhesive between the TP film 71 and the glass cover plate 70, thereby softening the adhesive and reducing the adhesive force of the adhesive. This heating method can effectively save electricity. The conventional heating method is that the glass cover plate 70 is in full contact with the loading platform 21, and the entire contact area is heated at the same time, so that more heat is required, and the heat dissipated to the environment is large. The use of a pressure roller method can effectively control the heat dissipation to the environment. In addition, in this embodiment, the preset size of the opening 23 is greater than or equal to the outline size of the TP film 71 and smaller than the outline size of the glass cover plate 70, and the length of the first heating roller 53 is longer than or equal to the longitudinal length of the TP film 71.

[0047] Furthermore, the first heating rollers 53 are two arranged side by side, and the heating device 50 also includes a second sliding seat 55, a second heating roller 56, and a third driving mechanism 57 for driving the second heating roller 56 to move up and down. The second sliding seat 55 is arranged on the third driving slide rail 51, and, in the direction of tearing the TP film 71, the second sliding seat 55 is located in front of the first sliding seat 52. The third driving mechanism 57 is arranged on the second sliding seat 55 and moves with the second sliding seat 55. The second heating roller 56 extends longitudinally and is connected to the third driving mechanism 57. The first heating roller 53 is provided with two strips, so that the heating area with the glass cover plate 70 can be increased, so that the heat transfer amount can be larger, and the softening speed of the adhesive of the TP film 71 can be accelerated, thereby improving the speed of tearing the TP film 71; by providing the second heating roller 56, in the actual process of tearing the TP film 71, the second heating roller 56 continuously moves back and forth at a preset distance in front of the first heating roller 53, which can not only reduce the temperature difference at different positions of the glass cover plate 70, but also heat and soften the adhesive of the TP film 71 to be torn in advance, thereby improving the softening effect and speed of the adhesive, and further improving the speed of tearing the TP film 71.

[0048] Furthermore, a buffer pad 24 is attached to the surface of the material loading platform 21 around the opening 23 , and the buffer pad 24 can prevent the glass cover plate 70 from being scratched due to friction with the material loading platform 21 .

[0049] Furthermore, the film tearing mechanism 60 also includes two fourth driving rails 62 and a tearing movable seat 63. The two fourth driving rails 62 are arranged on both sides of the transmission mechanism 20 in the horizontal direction, and the tearing movable seat 63 is longitudinally mounted between the two fourth driving rails 62. The plurality of aforementioned gripping devices 61 are arranged on the tearing movable seat 63 at intervals corresponding to the positions of the plurality of TP films 71. When the TP film 71 is actually torn, each of the gripping devices 61 grasps the end of each divided TP film 71, and then the tearing movable seat 63 moves and starts to tear the TP film 71. After the TP film 71 is torn off the glass cover 70, each gripping device 61 releases the TP film 71, and finally, the staff can take away the waste TP film 71. It should be noted that the method of driving the tearing movable seat 63 to move can be a motor or a pneumatic drive, as long as the tearing movable seat 63 can be driven, it is not limited.

[0050] Furthermore, the gripper device 61 includes a bracket 611, a bracket driving mechanism 612 for driving the bracket 611 to rise and fall, a mounting plate 613, a vacuum suction plate 614, a gripper 615, and a gripper driving mechanism 616. The bracket driving mechanism 612 is arranged on the aforementioned tearing movable seat 63. The upper end of the bracket 611 is connected to the bracket driving mechanism 612. The mounting plate 613 is connected to the lower end of the bracket 611. The vacuum suction plate 614 is connected to the bottom of the mounting plate 613. A vacuum suction hole is arranged at the bottom of the front end of the vacuum suction plate 614. The gripper 615 and the gripper driving mechanism 616 are arranged at the front end of the mounting plate 613. When working, the vacuum suction hole sucks the upper side of the end of the TP film 71, and the gripping part 617 of the gripper 615 is pressed on the lower side of the end of the TP film 71. In this way, the TP film 71 is grasped by the cooperation of the vacuum suction plate 614 and the gripper 615. Specifically, when grasping, the bracket driving mechanism 612 drives the bracket 611 to move downward, so that the vacuum suction hole contacts the upper side of the TP film 71 and sucks it. Then, the bracket driving mechanism 612 drives the bracket 611 to move upward, thereby sucking the TP film 71 up to a certain height. Then, the gripper driving mechanism 616 drives the gripper 615 to move, so that the gripping part 617 of the gripper 615 is pressed against the lower side of the TP film 71, thereby firmly grasping the TP film 71.

[0051] Furthermore, the outer side of the gripping portion 617 has an arc surface 618. When the TP film 71 is gripped and torn, the TP film 71 will be tightly pressed against the outer side of the gripping portion 617. The outer side of the gripping portion 617 is designed to be an arc surface 618, which has a smooth surface and will not cut or mark the TP film 71 and cause it to break.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
