Description

Technical Field

[0001] The utility model relates to the technical field of electronic screen production equipment, in particular to an electronic paper screen FPL laminating mechanism. Background Art

[0002] With the development of electronic technology, the concept of electronic paper (e-paper), also known as digital paper, has emerged. It is an ultra-thin, ultra-light display that can be understood as "paper-thin, flexible, and rewritable." E-paper combines the advantages of paper (such as a near-identical visual effect) with the ability to continuously refresh the displayed content like a typical LCD display. It is also thinner and lighter than LCDs, and consumes less power.

[0003] Electronic paper is mainly composed of thin film transistors (TFT), as well as IC, front panel (FPL), flexible printed circuit (FPC), anisotropic conductive adhesive (Anisotropic Conductive Adhesive) and other components. Film, ACF), etc., among which FPL laminating is an important link in the production process of electronic paper. In order to liberate manual labor and improve production efficiency, automated equipment is generally used for automatic material picking, film tearing, and laminating. For example, China Utility Model Patent CN215040403U (announcement date 2021.12.07) provides an FPL laminating machine, "through the film tearing mechanism to take the easy-to-tear sticker on the easy-to-tear sticker roll mechanism, and tear off the release film on the FPL on the FPL assembly, and then multiple patch mechanisms will tear off the FPL with the release film and the LCD after silver paste application on the patch platform. The use of multiple patch mechanisms and multiple patch platforms improves the efficiency of patching. The entire FPL laminating machine has a simple structure and is easy to install, debug and operate. The product changeover time is shortened, the applicability is strong, and it is compatible with products of various sizes for laminating". However, most FPL laminating machines generally adopt the method of directly covering the entire surface of the FPL in parallel and attaching it to the LCD / TFT. Before laminating, the air in the gap between the FPL and the LCD / TFT cannot be discharged in time, which is easy to generate bubbles and affect the laminating quality. Utility Model Content

Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 9 , an electronic paper screen FPL bonding mechanism, including a TFT material receiving mechanism a, an FPL feeding mechanism b, and an FPL attaching mechanism c:

[0033] The TFT material receiving mechanism a includes a TFT material receiving Y-axis guide rail a1 and a TFT material receiving platform a2 moving along the TFT material receiving Y-axis guide rail a1;

[0034] The FPL loading mechanism b includes an FPL silo b1, an FPL transfer platform b2, an FPL receiving platform b3, an FPL picking arm b4 that moves along the X and Z axis directions, and an FPL adjustment and transfer arm b5. It also includes an FPL receiving Y-axis guide rail b6 and an FPL film tearing assembly b7. The FPL receiving platform b3 slides along the FPL receiving Y-axis guide rail b6. The FPL silo b1, the FPL transfer platform b2, and the FPL receiving platform b3 are arranged along the X axis direction. The FPL picking arm b4 grabs the FPL film sheet from the FPL silo b1 and sends it to the FPL transfer platform b2. The FPL adjustment and transfer arm b5 then transfers the FPL film sheet from the FPL transfer platform b2 to the FPL receiving platform b3.

[0035] The FPL attachment mechanism c includes an FPL attachment drive arm c1 that moves along the X and Z axes, and an FPL attachment head c2 mounted on the FPL attachment drive arm c1. The FPL attachment head c2 includes an FPL attachment mounting plate c21 connected to the FPL attachment drive arm c1, and an FPL suction plate c22 hingedly connected to the FPL attachment mounting plate c21. A rotation angle adjustment cylinder c23 is hingedly mounted on the FPL attachment mounting plate c21, and the telescopic rod of the rotation angle adjustment cylinder c23 is hingedly connected to the side of the FPL suction plate c22.

[0036] The FPL attaching mounting plate c21 is also equipped with an attaching roller lifting cylinder c24, the telescopic rod of which is connected to a film pressing roller frame c25, and the film pressing roller frame c25 is provided with an attaching rubber roller c26 which is rotatably connected thereto.

[0037] Specifically, when removing the FPL, the FPL adsorption plate c22 is retracted by the rotation adjustment cylinder c23 to a horizontal position. After the FPL is adsorbed from the FPL receiving platform b3, the film is removed by the FPL film tearing assembly b7. When attaching, the FPL adsorption plate c22 is extended by the rotation adjustment cylinder c23 to form an angle with the horizontal plane. The attachment roller lifting cylinder c24 drives the attachment rubber roller c26 to press down one side of the FPL onto the TFT. Then, the TFT receiving platform a2 moves along the TFT receiving guide rail to cooperate with the attachment rubber roller c26 to press the FPL onto the TFT. The utility model adopts an inclined attachment method to facilitate the timely discharge of air and reduce the generation of bubbles. In addition, the attachment rubber roller c26 is used to roll the FPL to further eliminate bubbles and improve the quality of the attachment. The utility model has a high degree of automation, which improves production efficiency and attachment accuracy.

[0038] Furthermore, an FPL attachment rotating motor c11 is mounted on the FPL attachment driving arm c1, and an FPL attachment mounting plate c21 is fixedly connected to the rotating shaft of the FPL attachment rotating motor c11. The FPL attachment mounting plate c21 is driven by the FPL attachment rotating motor c11 to rotate on the XY plane.

[0039] The FPL material receiving Y-axis guide rail b6 is provided with an FPL material receiving slider b61 which slides with it, and the FPL material receiving platform b3 is fixedly mounted on the FPL material receiving slider b61. The FPL film tearing assembly b7 includes an FPL film tearing lifting assembly b71 which is arranged on the FPL material receiving slider b61 and can be lifted and lowered in the Z axis, and an FPL film tearing vertical mounting plate b72 which is driven to lift and lower by the FPL film tearing lifting assembly b71. An FPL film tearing rotating motor b73 is fixedly mounted on the FPL film tearing vertical mounting plate b72, and an FPL film tearing clamping finger cylinder b74 which rotates in the YZ plane is connected to the rotating shaft of the FPL material tearing rotating motor b73. A waste film receiving frame b75 is provided at the front end of the FPL material receiving Y-axis guide rail b6.

[0040] Specifically, when performing the film tearing operation, the FPL attachment mounting plate c21 is driven by the FPL rotating motor to rotate a certain angle, so that a corner of the FPL sheet on the FPL adsorption plate c22 is aligned with the clamping finger of the FPL film tearing finger cylinder b74 to facilitate angle film tearing.

[0041] Furthermore, an easy-tear sticker discharging component d is provided above the FPL material splicing Y-axis guide rail b6. The easy-tear sticker discharging component d includes an easy-tear sticker discharging bracket d1 and an easy-tear sticker roll d2 and a waste film recovery roll d3 rotatably mounted on the easy-tear sticker discharging bracket d1. An easy-tear sticker guide roller d4 is also installed on the easy-tear sticker discharging bracket d1. A notch corresponding to the clamping finger of the FPL film tearing finger cylinder b74 is provided at the bottom of the easy-tear sticker discharging bracket d1. The easy-tear sticker roll d2 releases the easy-tear sticker tape e, and the easy-tear sticker tape e bypasses the easy-tear sticker guide roller d4 and passes through the notch and is recovered by the waste film recovery roll d3.

[0042] Furthermore, a roller driving cylinder b741 and a roller guide slide b742 are fixedly installed on one of the clamping fingers of the FPL film tearing clamping cylinder b74; a roller mounting slider b743 which slides with the roller guide slide b742 is connected to the telescopic rod of the roller driving cylinder b741; and a glue pressing roller b744 is rotatably installed on the roller mounting slider b743.

[0043] Specifically, before tearing the film, the FPL film tearing clamp finger cylinder b74 tears the easy-tear tape from the notched easy-tear tape e, and sticks the easy-tear tape to a corner of the protective film on the FPL sheet when tearing the film. Then the roller drive cylinder b741 drives the glue pressing roller b744 to roll back and forth to stick the easy-tear tape to the protective film. Then the FPL film tearing clamp finger cylinder b74 clamps the easy-tear tape and cooperates with the FPL film tearing lifting component b71 and the FPL film tearing rotating motor b73 to complete the film tearing, and then the FPL adsorption plate c22 rotates and resets.

[0044] Furthermore, the notch is provided with a material strip pressing block d11 fixedly mounted on the easy-to-tear adhesive material unloading bracket d1 and a material strip clamping cylinder d12. The telescopic rod of the material strip clamping cylinder d12 is connected to an L-shaped clamping strip d13 located below the material strip pressing block d11. The easy-to-tear adhesive tape e passes through the bottom of the material strip pressing block d11. Specifically, Figure 6 As shown, during the process of removing the easy-tear tape, the tape clamping cylinder d12 drives the L-shaped clamping strip d13 to cooperate with the tape pressing block d11 to clamp the easy-tear tape e, so that the FPL film tearing clamping finger cylinder b74 can tear the easy-tear tape and prevent the easy-tear tape e from being pulled out.

[0045] Furthermore, an FPL lift plate b11 is provided within the FPL hopper b1, which rises and falls along the Z-axis. A discharge sensor b12 is provided at the opening of the FPL hopper b1. Preferably, the FPL lift plate b11 is driven upward and downward by a motor-screw mechanism controlled by signals from the discharge sensor b12. Each time the FPL retrieving arm b4 removes a piece of FPL, the motor-screw mechanism drives the FPL lift plate b11 to raise the thickness of the piece, facilitating continuous material retrieval.

[0046] Furthermore, the FPL transfer platform b2 is provided with an FPL throwing material Y-axis guide rail b21, an FPL throwing material tray b22 sliding along the FPL throwing material Y-axis guide rail b21, and an FPL throwing material driving cylinder b23 driving the FPL throwing material tray b22 to move. The horizontal height of the FPL throwing material tray b22 is higher than the FPL transfer platform b2. During the storage of FPL, two or more pieces of FPL are easily stuck together due to static electricity or viscosity. Preferably, the discharge sensor b12 is a laser thickness sensor, which determines whether multiple pieces of FPL are grabbed at one time through thickness detection. If multiple pieces of FPL are grabbed, the FPL throwing cylinder drives the FPL throwing material tray b22 to move to the FPL transfer platform b2 to catch the FPL that has been picked up incorrectly. Better, if Figure 9 As shown, a shaking cylinder b41 is provided on the FPL picking arm b4, and the telescopic rod of the shaking cylinder b41 is connected to the picking suction cup b42 for grabbing the FPL. After the FPL is picked up, the sticky FPL can be shaken off by driving the picking suction cup b42 to shake through the shaking cylinder b41, thereby reducing the phenomenon of grabbing multiple pieces of FPL.

[0047] Furthermore, a film material detection Y-axis guide rail f1 and a film material detection CCD camera f2 moving along the film material detection Y-axis guide rail f1 are provided below the FPL attaching mechanism c, and a defective material ejection tray f3 is fixedly installed on one side of the TFT material receiving platform a2.

[0048] Furthermore, an X-axis g1 guide rail for attachment detection and an attachment detection CCD camera g2 moving along the X-axis g1 guide rail for attachment detection are installed above the TFT material receiving mechanism a.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
