Whole pasting method for light bar and double faced adhesive tape

Abstract

The invention provides a whole pasting method for a light bar and double faced adhesive tape. The whole light bar and the whole double faced adhesive tape are pasted through whole arrangement and counterpoint stamping. The method specifically comprises the following steps that an LED is wholly welded to an FPC; a double faced adhesive tape assembly is cut according to the outline of the FPC to obtain a double faced adhesive tape plate block, and the double faced adhesive tape assembly is composed of the double faced adhesive tape, a first release film and a second release film, wherein the first release film and the second release film are pasted on the two opposite faces of the double faced adhesive tape respectively; the first release film on the double faced adhesive tape plate block is subjected to hollowed-out processing corresponding to the position of the LED on the whole FPC; the double faced adhesive tape plate block is pasted on the whole FPC in the direction that the first release film is close to the whole FPC through a positioning jig; the whole FPC on which the double faced adhesive tape plate block is pasted is subjected to outline stamping through a stamping die, and the LED which is wholly arranged and is provided with the double faced adhesive tape and the second release film in a pasted mode is acquired. According to the whole pasting method for the light bar and the double faced adhesive tape, the pasting speed is greatly increased, the efficiency is improved, and the labor cost is lowered.

Description

technical field [0001] The invention relates to the technical field of backlight module assembly, in particular to a method for pasting a light bar and a double-sided adhesive plate. Background technique [0002] With the full popularity of smart phones and the continuous innovation of technology, mobile phone products are characterized by rapid updates, low prices, and strict quality, and the competition among major mobile phone manufacturers is becoming increasingly fierce. In this context, the price will undoubtedly become a powerful weapon to defeat the opponent. Therefore, low cost has become an issue that everyone pays more and more attention to. Based on the above, the cost pressure is spread to various mobile phone parts suppliers.
