Description

Technical Field

[0001] This utility model relates to the field of LCD screen processing, specifically to an attachment machine. Background Technology

[0002] A liquid crystal display (LCD) is a flat panel device that uses liquid crystal materials to control light transmission to display images. Its core structure consists of a liquid crystal layer sandwiched between two parallel glass plates and a polarization filter. This design gives it advantages such as small size, light weight, low power consumption (microwatt level), and no radiation, and it is widely used in devices such as smartphones, televisions, and computer monitors. However, in the manufacturing process of LCD screens, to achieve "electrode conductivity," an "anisotropic conductive film (ACF)," or "film application," needs to be applied. Currently, the film application process involves directly applying the ACF to the LCD screen. Because no "further compression application" is performed, air bubbles may exist between the LCD screen and the ACF, affecting the quality of the LCD screen. Utility Model Content

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] Example 1 like Figures 1 to 4 As shown, an adhesion bonding machine has undergone a series of design improvements based on the original design. This adhesion bonding machine can further extrude and adhere liquid crystal displays (LCDs) to films (anticotropic conductive adhesive films). The improved adhesion bonding machine structurally includes an adhesion operation table 1, which is mounted on a base frame. The base frame is used to stabilize the adhesion operation table 1 and other structures on it. A placement base 11 for placing the LCD screen to be adhered to is mounted on the top surface of the adhesion operation table 1. A limiting mechanism for contacting the film to be adhered to the LCD screen is movably disposed above the placement base 11. The limiting mechanism is connected to the adhesion operation table 1 via a bracket 2. An extrusion mechanism for further extruding the adhered film to the LCD screen is movably mounted on the bracket 2. The extrusion mechanism includes a rotating roller 3, which is rotatably connected to a rotating mounting base 31 via a rotating shaft. A movable mechanism for driving the rotating mounting base 31 to move up and down is mounted on the top of the rotating mounting base 31.

[0013] In this embodiment, the liquid crystal screen to be coated with a film is placed on the placement base 11, and the placement base 11 limits and fixes the liquid crystal screen to be coated with a film. Then, the film to be coated passes through the liquid crystal screen on the placement base 11. At this time, the limiting mechanism is controlled to "limit" the film to be coated with the liquid crystal screen, so that the film to be coated with the liquid crystal screen "contacts" with the liquid crystal screen. Then, the movable mechanism on the pressing mechanism is controlled to drive the rotating roller 3 on the rotating mounting base 31 to "move" and contact the liquid crystal screen with the film coated below. By driving the rotating roller 3 to "roll and move" to contact the liquid crystal screen with the film coated below, "contact compression" is performed between the two to reduce defects such as air bubbles between the liquid crystal screens with the film coated, and to ensure the quality of the processed liquid crystal screen.

[0014] Example 2 Based on Embodiment 1, the limiting mechanism includes a limiting plate 4, which is movably disposed between the rotating roller 31 and the placement base 11. A cylinder 41 is provided at the top of the limiting plate 4 to drive its lifting and lowering movement. The output end of the cylinder 41 is connected to the limiting plate 4, and the cylinder body is connected to the extrusion guide plate 42 via a fixing plate. Extrusion plate electric guide rails 43 are respectively provided at both ends of the extrusion guide plate 42 to drive its horizontal movement. Support plates are connected to both ends of the extrusion plate electric guide rails 43, and the other end of the support plates is used to connect and fix to the attachment operating table 1. One end of each of the two extrusion plate electric guide rails 43 is connected to the bracket 2 via a connecting frame.

[0015] In this embodiment, the film to be applied is subjected to an "external force" (existing technology, a force that moves the film to be applied) to pass through the end face of the LCD screen on the placement base 11 where the film needs to be applied. Then, by controlling the two electric guide rails 43 of the extrusion plates to "start", the limiting plate 4 on the extrusion guide plate 42, which is movably connected by the cylinder 41, is moved to a suitable distance from one end of the LCD screen where the film needs to be applied. Then, by controlling the cylinder 41, the limiting plate 4 is moved downward toward the LCD screen where the film needs to be applied, so that the film to be applied "contacts" the LCD screen. At this time, by controlling the electric guide rails 43 of the extrusion plates to move the limiting plate 4 toward the other end of the LCD screen on the placement base 11 according to the distance and height at which the film to be applied "contacts" the LCD screen, so that the film to be applied covers the entire LCD screen.

[0016] Example 3 Furthermore, in order to further ensure the quality of the attached film and the LCD screen (especially to reduce air bubbles between them), the rotating roller 3 on the extrusion mechanism is controlled to roll and press the film and the LCD screen "multiple times", thereby reducing the probability of air bubbles between them.

[0017] The movable mechanism for driving the rotating roller 3 (including lifting and lowering, and horizontal movement of the rotating roller 3) includes a lifting hydraulic rod 32. The output end of the lifting hydraulic rod 32 is connected to the rotating mounting base 31. The cylinder of the lifting hydraulic rod 32 is connected to the movable plate 33 via a fixed frame. The movable plate 33 is horizontally movably positioned above the placement base 11. Vertical movable guide rods 34 are respectively provided on both sides of the lifting hydraulic rod 32. One end of the vertical movable guide rod 34 is connected to the rotating mounting base 31, and the other end of the vertical movable guide rod 34 movably passes through the movable plate 33.

[0018] Furthermore, an electric movable guide rail 35 is installed and connected on the movable plate 33. The electric movable guide rail 35 is horizontally positioned above the placement base 11, and both ends of the electric movable guide rail 35 are used to connect and fix to the top of the bracket 2. Horizontal guide rods 36 are respectively provided on both sides of the electric movable guide rail 35. The horizontal guide rods 36 movably pass through the horizontal movable guide block 37, and both ends of the horizontal guide rods 36 are used to connect and fix to the top of the bracket 2. The horizontal movable guide block is used to connect and fix to the movable plate 33.

[0019] In this embodiment, by controlling the lifting hydraulic rod 32 to "lift and lower," the rotating roller 3, rotatably connected to the rotating mounting base 31, moves up and down under the "vertical guidance" of the vertical guide rod 34, thereby adjusting the contact height between the rotating roller 3 and the LCD screen on the lower base 11, which has already been coated with film. Then, by controlling the electric movable guide rail 35 to "move horizontally," the movable plate 33 moves horizontally under the "horizontal guidance" of the horizontal guide rod 36, thereby enabling the rotating roller 3, rotatably connected to the rotating mounting base 31, to "roll in contact" with the LCD screen on the lower base 11, which has already been coated with film. By controlling the rotating roller 3 to "roll back and forth" repeatedly, air bubbles between the coated film and the LCD screen are reduced, thereby improving product quality.
