Smooth LED flexible light bar and device and method for manufacturing same

Abstract

The invention discloses a smooth LED flexible light bar and a device and a method for manufacturing the same in the technical field of electronic lighting applications. The smooth LED flexible light bar is composed of a viscous material layer and a flat conductor adhesively bonded to the surface of the viscous material layer, a bonding layer used for bonding the flat conductor covers the surface of the viscous material layer, empty avoiding holes are punched in the surface of the viscous material layer, fracture surfaces used for disconnecting the flat conductor are punched in the surface of the flat conductor, the center of each fracture surface corresponds to the corresponding center of each empty avoiding hole, the fracture surfaces are located right above the empty avoiding holes, and electron components used for connecting the fracture surfaces are welded to the surface of the flat conductor. Compared with a conventional LED flexible light bar, the smooth LED flexible light bar has the advantages that a PI basement membrane and a PI surface membrane which are high in cost are omitted, the PI basement membrane is replaced through another low-cost viscous material layer such as a PET membrane, and the surface membrane can be omitted, so that the smooth LED flexible light bar is simple in integral structure, manufacturing cost can be saved, and wide promotion is facilitated.

Description

[0001] technical field [0002] The invention relates to the technical field of electronic lighting applications, in particular to a bare LED flexible light bar, equipment for manufacturing the bare LED flexible light bar, and a method for manufacturing the bare LED flexible light bar. Background technique [0003] The flexible LED light strip uses FPC as the assembled circuit board and SMD LEDs for assembly, so that the thickness of the product is only the thickness of a coin and does not take up space; the general specifications are 30cm long, 18 LEDs, 24 LEDs and 50cm long 15 LEDs, 24 LEDs, 30 LEDs, etc. There are also 60cm, 80cm, etc. Different users have different specifications. And it can be cut or extended at will without affecting the luminescence. The FPC material is soft, can be bent, folded, and wound at will, and can be moved and stretched in three-dimensional space without breaking. It is suitable for use in irregular places and places with small spaces, and...

Problems solved by technology

Due to the high cost of the PI base film and PI mask, the production cost of the flexible LED light strip is also high, and in the production process, the PI base film and the PI mask need to be punched separately, and multiple laminations are required at the same time. Process, the equipment used in the overall production process is more, which makes the production process of the product more cumbersome, resulting in a large investment in the overall production process

In addition, the traditional production process produces semi-finished products of flexible LED strips, which do not include the process of patching and welding electronic components, and other processes need to be invested to complete the finished product
