Description

A grabbing device for producing reflective screens

Technical Field

The utility model relates to the technical field of reflective screen production, in particular to a grabbing device for reflective screen production.

Background Art

The reflective screen is a screen that has reflective material installed under the LCD panel to replace the luminous material of the transmissive reflective screen. When the ambient light is sufficient, it uses the light reflected by the mirror surface to illuminate the screen. However, it cannot display clearly in dark places because the weak ambient light is not enough to be reflected to illuminate the screen. This kind of reflective screen that can only passively receive reflected ambient light is a passive reflective LCD screen. Color screen PDAs do not use passive reflective reflective screens.

However, in the prior art, a single suction cup often has the problem of unstable adsorption when facing a large-sized reflective screen. During the grabbing process, the reflective screen is easy to detach from the suction cup, or during the lowering process, the corners hit the target point due to deflection, causing damage to the reflective screen. Multiple suction cups cannot be adjusted for reflective screens of different sizes. When the reflective screen is too large, it faces the same difficulty as a single suction cup. When the reflective screen is too small, it cannot contact the reflective screen, so the practicality is low.
