Description

Adhesive tape with flat conductor

Technical field

The utility model is related to a kind of accessories fields of LED light strip.

Background technology

In the prior art, LED light is with a kind of production process and construction such as Chinese patent literature CN

203131554U's【0039】、【0041】[0042] described in section, the short light bar of LED is made：It is soft by what is made LED short-term roads plate 1 ' (as shown in Figure 1), SMT paster LEDs lamp 2 and resistance 3 weld LED light 2 and resistance 3 by Reflow Soldering On flexible LED wiring board 1 ', flexible LED lamp belt 1 (as shown in Figure 2) is formed；Make winding displacement：Simultaneously by one group of flat conductor 6 Cloth is vacuumized by means of vacuum-pumping tube 5 along direction V in one group of parallel slot 4 of mold (as shown in Figure 5), and will be flat Conducting wire 6 is fixed in slot 4, (as shown in Figure 6), then clings the flat conductor 6 being fixed in slot 4 sticky insulated rubber film 7 It is fixed, it is removed from the molds, to be fabricated to the winding displacement (as shown in Figure 7) for including two or more parallel flat conductors 6；System Make LED long light bar：Winding displacement is cut into the winding displacement comprising such as two flat conductors 6 (such as Fig. 8 institutes by length as needed Show), by posted the short light bar 1 of LED element along winding displacement longitudinal direction (i.e. the length direction of flat conductor 6) one by one It is pasted onto on winding displacement.Arrangement between short light bar 1 on winding displacement can be along the longitudinal direction of winding displacement and there are certain interval, interval It is big neglect application scenario depending on.Certainly, it will be understood by those skilled in the art that can also hardly remain spaced.Then, tin is used Weldering 8 respectively by the positive and negative anodes (such as solder joint) at the both ends of the short light bar of LED 1 it is corresponding be welded on winding displacement respective flat conducting wire 6 (such as It corresponds to solder joint position) on.As needed, then such as injection molding machine can be used to carry out injection molding sealing, is just fabricated to grouping circuits plate LED long light bar (as shown in Figure 9).

It can be seen that the making of above-mentioned long light bar is first to make winding displacement and short light bar, wherein short light bar is to weld on circuit boards LED is formed, and has gap between the adjacent flat conducting wire of winding displacement side by side, short light bar 1 is by between being pasted onto between winding displacement flat conductor It is attached on winding displacement on the sticky insulated rubber film 7 of gap position, the positive and negative anodes at short light bar both ends are welded on different flat conductors On, still, an apparent problem is the automated production for first making short light bar and being unfavorable for long light bar, and Second Problem is short lamp It relies on 1 and is attached on winding displacement on the sticky insulated rubber film 7 of interstitial site between being pasted onto winding displacement flat conductor, due to flat Conducting wire is between short light bar and sticky insulated rubber film 7, if the gap of adjacent flat conducting wire is less than short light bar width, short light bar It may can not be pasted with sticky insulated rubber film 7, under such a configuration, in order to realize that short light bar is pasted onto sticky insulated rubber film comprehensively 7, the gap of adjacent flat conducting wire must be wide with short light bar, and the width of short light bar is significantly wider than so as to cause the width of winding displacement, Waste material.To the patented technology why not sticky insulated rubber film 7 be arranged between short light bar and flat conductor, reason exists It is continuous in the flat conductor for making winding displacement and sticky insulated rubber film 7, because of the barrier of continuous sticky insulated rubber film 7, short light bar It can not accomplish Machine automated welding with flat conductor, can not complete to be electrically connected.

Utility model content

The purpose of this utility model is to provide the adhesive tape with flat conductor, in order to which LED light strip can realize automatic metaplasia Production.

Adhesive tape with flat conductor, which is characterized in that including：The release film of strip has two in release film one side Or the flat conductor that a plurality of interval is arranged side by side；Multiple strip and block viscosity film units arrange, compartment of terrain along release film length direction It is pasted onto release film to be disposed in the one side of flat conductor, is in interrupted shape there are gap between adjacent viscosity film unit.

The beneficial effects of the utility model are：

When the adhesive tape with flat conductor is applied to LED light strip manufacture, one or more flexible circuit board is pasted onto viscous Property film unit on, due to multiple strip and block viscosity film units, arranged along release film length direction, be respectively adhered on release film arrangement Have in the one side of flat conductor, there are gaps between adjacent viscosity film unit, in this way can be located at flexible circuit board positive and negative electrode viscous Property film unit region except namely flexible circuit board positive and negative electrode be located at the interstitial site between sticky film unit, such adhesive film Unit will not obstruct flexible circuit board positive and negative electrode and be welded with conducting wire, be conducive to the automation of flexible circuit board positive and negative electrode and conducting wire Welding, this structure are conducive to adhesive film being placed between conducting wire and flexible circuit board, make flexible PCB and sticky film unit Combination with conducting wire is stablized.
