Device for aligned binding hard protecting film

Abstract

A device is used for binding a hard protective membrane with alignment onto a LCD display modole. It consists of a plate with upper and lower surfaces and several notches, a rotary mechanism connected with the lower surface and a bottom plate pivoted on the rotary mechanism with the plate said above. The said upper surface is used for holding a LCD module and a hard protective membrane with notches aligned with binding positions of adhesive tapes on the sides of the module and the membrane. Also, several positioning blocks are arranged on the upper surface to engage with the edges of the LCD module and the said membrane.

Description

technical field [0001] The invention relates to a hard protective film alignment sticking device, which is suitable for the alignment between a liquid crystal display module and a hard protective film, and is pasted on the liquid crystal display module and the hard protective film with tape after the alignment sides of the . Background technique [0002] Liquid crystal displays have the advantages of high image quality, small size, light weight, low voltage drive, low power consumption, and wide application range. At present, it has been widely used in consumer electronics or computer products such as small and medium-sized portable TVs, mobile phones, video recorders, personal digital assistants, notebook computers, desktop monitors, and projection TVs, and has gradually replaced cathode ray tubes. (Cathode Ray Tube, CRT) has become the mainstream of displays. [0003] The main body of a general crystal display is a liquid crystal unit, which is mainly composed of two tra...

AI Technical Summary

Problems solved by technology

[0007] (1) The hard protective film is attached to the position by manual visual inspection, which is prone to poor alignment of the hard protective film, so that the polarizer on the part of the liquid crystal display module is exposed, thus causing dust adhesion or It is a phenomenon of abrasion and scratching

[0008] (2) The alignment of the hard protective film is carried out by manual visual inspection, and it is easy to make the outer edge of the hard protective film exceed the allowable error range of the alignment, so the alignment must be performed again

[0009] (3) Carrying out the alignment sticking of the hard protective film by manual visual inspection is prone to poor alignment of the hard protective film, which in turn makes it easy for the operator to press and move the hard protective film when re-aligning. Alignment, causing the hard protective film to wear or scratch the surface of the upper polarizer of the liquid crystal display module, resulting in poor quality of the finished product, resulting in greater losses

[0010] (4) Carry out the alignment sticking of the hard protective film by artificial visual method. In the case of no auxiliary device, in order to improve the alignment accuracy of the hard protective film, it will take a lot of manual adjustment time, so it is impossible Effectively improve work efficiency

[0011] (5) Carrying out the alignment and pasting of the hard protective film by artificial visual inspection is likely to cause visual fatigue of the operator, so after a long time of operation, it will seriously affect the quality of the alignment and pasting of the hard protective film
