Description

Technical Field

[0001] This utility model relates to the field of touch screen manufacturing technology, and in particular to a pressing device for touch screen manufacturing. Background Technology

[0002] The full lamination technology of industrial touch screens is a bonding process that uses water-based adhesive or optical adhesive to completely and seamlessly bond the LCD screen and the touch panel (TP) together. OCA adhesive and LOCA water-based adhesive are commonly used. OCA adhesive is mainly suitable for bonding small-sized LCD products.

[0003] A Chinese patent, CN219302809U, discloses a pressing device for touchscreen production. This device, through the cooperation of a sliding plate, drive motor, cylinder, wiping cloth, moving component, and dust collection component, can automatically remove dust that may adhere to the touch panel. This significantly improves the efficiency of touchscreen production and bonding, avoids the inconvenience of manual wiping, greatly reduces the labor intensity of workers, and facilitates user convenience. However, the wiping cloth, when wiping multiple panels, becomes relatively rough due to friction with the panels, accelerating wear on both the panels and the wiping cloth. The wiping cloth, mounted on a cylinder, is time-consuming to replace, leading to reduced production efficiency. Even after being processed by a suction pump, the wiping cloth may still retain some tiny particles or fibers, which can still cause minor scratches on the touchscreen during wiping. Some special impurities require appropriate cleaning agents for removal. Therefore, this patent proposes a pressing device for touchscreen production to solve these problems. Utility Model Content

The inner side of the wiping cloth 4 is pressed against the cleaning roller 5, and the outer side is in contact with the panel. The housing 3 is provided with a winding assembly 6 for winding up the wiping cloth 4. The inlet pipe 7 is set inside the housing 3, and the other end extends to the outside. A nozzle 71 is set on the left side of the inlet pipe 7. The nozzle 71 is set at an angle. The housing 3 is provided with a limiting assembly 8 for restricting the wiping cloth 4 and the nozzle 71.

[0021] In this invention, a panel is placed on the base 1, and an adsorption and pressing assembly is provided on the bracket 2 for adsorbing the LCD screen and then pressing it down onto the panel. The adsorption and pressing assembly includes an electric push rod, a fan, a blower hood, a vacuum frame, a suction cup, and a vacuum pump. A dust collection assembly is provided on the left side of the housing 3, which includes a dust collection hood, a filter cloth, and a suction pump. The dust collection assembly adsorbs any dust that may be stirred up. Then, the electric push rod is activated to move the adsorption assembly downwards, causing the adsorbed LCD screen to move down and adhere to the touch panel, completing the pressing process and preventing dust from falling onto the touch panel. The housing 3 is moved using a moving assembly, which includes a linear drive module. The moving end of the linear drive module is connected to the rear side of the housing 3. The lower end is equipped with a pulley that slides into the inner wall of the groove at the top of the base 1. The wiping cloth 4 is placed inside the housing 3. The wiping cloth 4 is a large roll. A portion of the wiping cloth 4 is pressed down by the cleaning roller 5 to make the wiping cloth 4 adhere to the panel. The wiping cloth 4 is wound up by the winding assembly 6, so that the wiping cloth 4 passing through the cleaning roller 5 is always brand new. After the wiping cloth 4 is placed on the winding assembly 6, it can be replaced after the whole roll is used up. At the same time, a liquid inlet pipe 7 and a nozzle 71 are provided to spray a cleaning agent suitable for the touch screen panel onto the wiping cloth 4 to improve the cleaning quality of the panel and prevent some fingerprints and stains from being difficult to remove. A limit assembly 8 is provided to restrict the wiping cloth 4 during winding and unwinding to prevent it from falling off.

[0022] In an optional embodiment, a cover 31 is provided on the front side of the box 3, and a partition 32 is provided inside the box 3.

[0023] It should be noted that the cover 31 facilitates the replacement of the wiping cloth 4.

[0024] In an optional embodiment, the winding assembly 6 includes a motor 61, a winding roller 62, and an unwinding roller 63. The motor 61 is disposed on the rear side wall of the housing 3. One end of the winding roller 62 is coaxially connected to the output shaft of the motor 61, and the other end extends to the front side of the partition 32. One end of the unwinding roller 63 is rotatably connected to the rear side wall of the housing 3, and the other end extends to the front side of the partition 32. The wiping cloth 4 is disposed on the unwinding roller 63, and the other end is tightly wound with the winding roller 62.

[0025] It should be noted that when the wiping cloth 4 is placed on the unwinding roller 63, when the housing 3 is moving, the starting motor 61 drives the take-up roller 62 to rotate, and the wiping cloth 4 is continuously pulled, so that the brand-new wiping cloth 4 wipes and cleans the panel.

[0026] In an optional embodiment, the bottom of the housing 3 is provided with a sliding window, the size of which is adapted to the size of the cleaning roller 5.

[0027] In an optional embodiment, the right side of the inlet pipe 7 is connected to a flexible tube 72.

[0028] It should be noted that the other end of the hose 72 is connected to a container containing cleaning agent.

[0029] In an optional embodiment, the housing limiting assembly 8 includes a first pressure plate 81, a first pressure roller 82, a first spring 83, a second pressure plate 84, a second pressure roller 85, a limiting rod 86, and a second spring 87. The first pressure plate 81 is slidably connected to the bottom wall of the housing 3. The nozzle 71 is disposed on the first pressure plate 81. The first pressure roller 82 is disposed on the left side of the first pressure plate 81 and presses against the wiping cloth 4. The first spring 83 is sleeved on the liquid inlet pipe 7, and its two ends are respectively connected to the first pressure plate 81 and the right side wall of the housing 3. The limiting rod 86 is disposed on the top of the housing 3 and extends into its interior. The second pressure plate 84 is disposed on the bottom end of the limiting rod 86. The second pressure roller 85 is disposed on the bottom end of the second pressure plate 84 and presses against the wiping cloth 4. The second spring 87 is sleeved on the limiting rod 86, and its two ends are respectively connected to the top end of the second pressure plate 84 and the top wall of the housing 3.

[0030] It should be noted that when the take-up roller 62 and the unwind roller 63 are winding and unwinding, the roll formed by the wiping cloth 4 wrapped around them becomes larger or smaller. By setting the elasticity of the first spring 83 and the second spring 87, no matter how large the roll formed by the wiping cloth 4 is, the first pressure roller 82 and the second pressure roller 85 can squeeze it and prevent it from deviating during winding and unwinding. The nozzle 71 is set on the first pressure plate 81. As the roll of the wiping cloth 4 becomes larger or smaller, the nozzle moves with the first pressure plate 81 and always maintains a certain distance from the wiping cloth 4 to spray it evenly.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
