Description

A kind of ACF material volume automatic disconnecting device and ACF press-loading device

Technical field

The utility model relates to liquid crystal display technical field more particularly to a kind of ACF material volume automatic disconnecting devices and ACF Press-loading device.

Background technique

ACF is anisotropy electric conductor, on one side not have sticking release film, is closed on one side for resin adhesive after heating At resin conductive layer.Resin layer and circuit board (PCB) are pressed in processing procedure, are heated, and are melted, then pcb board can be connected after cooling down On metal electrode.ACF is made generally in the storage of material volume form and is used in industrial application.

ACF cutting mechanism is general as shown in Figure 1, ACF material strip is placed using charging tray 1 ' by this mechanism, by motor in the prior art It drives charging tray 1 ' to rotate, drives charging tray 1 ' to cutting assembly 2 ' for ACF material strip 6 '.2 ' two sides of cutting assembly are provided with the first absorption Component 3 ' and the second absorbent module 4 '.

Wherein, the first absorbent module 3 ' is set between cutting assembly 2 ' and charging tray 1 ', when ACF cutting mechanism works, the One absorbent module 3 ' and the second absorbent module 4 ' are adsorbed and are closely attached on ACF tape surface, and material strip generation vibration when cutting is avoided to make Cutting generates deviation.

Cutting assembly 2 ' includes single cutter, and precision commonly reaches cutting ACF resin interval 60 ' every time, but can not Cut off release film 61 '.After cutter 7 ' cuts off ACF resin interval 60 ', it is transported to pressure head component 5 ', ACF after molding to cutting Resin interval 60 ', is pressure bonded to circuit board 8 '.Later again by tearing mould guide wheel separation release film 61 ' and ACF resin interval 60 '.

As shown in Figures 2 and 3, above-mentioned ACF cutting mechanism, the length of the ACF pressed every time is by between two cut-out point A ACF length determine, cutting-off process is as shown in Fig. 2, i.e. processing procedure precision is determined by the running accuracy of 1 ' motor of charging tray, after pressing The required precision that must assure that dyestripping point B with greater need for dyestripping guide wheel 9 ', every section of ACF after can making cutting press to circuit board ACF on 8 ' is qualified.

But 7 ' blade thickness of cutter is thin, and after cutter 7 ' cuts off ACF resin interval 60 ', two neighboring ACF resin interval There was only a fine crack between 60 ', in actual production, because of the vibration that process equipment generates, machining accuracy lamp problem leads to ACF tree Rouge interval 60 ' is difficult to ensure completely isometric after cutting off.Meanwhile because shearing length is unstable, cause the positioning of dyestripping point B location difficult, It is as also shown in fig. 3, because of the fault-tolerant deficiency in position of subsequent pressing pressure head and dyestripping guide wheel 9 ', if the ACF resin interval after cutting 60 ' is more to the rear than the position of circuit board 8 ' during transportation, then pressure head can not press completely or dyestripping guide wheel 9 ' tears release film 61'；If the ACF resin interval 60 ' after cutting is more to the front than the position of circuit board 8 ' during transportation, it is likely that press next A ACF resin interval 60 ', leads to next product deficient manufacturing procedure.
