Gluing device for ultra-long flexible LED light source

Abstract

The invention provides a gluing device for an ultra-long flexible LED light source and belongs to the field of manufacturing of LED lighting products. The gluing device for the ultra-long flexible LEDlight source consists of a gluing bottom plate and a gluing support. The gluing support is used for straightening during gluing of a FPC (flexible printed circuit) substrate of the ultra-long flexible LED light source and glue baking and setting after dispensing. A movable stretching mechanism is arranged on the gluing support and can strengthen the flexible substrate of the ultra-long flexible LED light source to facilitate dispensing of the dispensing process. The gluing base provides accurate positioning and bearing functions for the gluing support. Platform type support tables and semicircular groove support channels of the FPC substrate of the ultra-long flexible LED light source product are arranged on the gluing base. The flexible substrate of the ultra-long flexible LED light source product is strengthened under the action of the movable stretching mechanism of the gluing support and placed on the platform type support tables and the semicircular groove support channels of thegluing base, so that the FPC substrate is ensured to be in a horizontal straight state, and gluing operation of an automatic machine is facilitated.

Description

technical field [0001] The invention relates to the field of LED product manufacturing, in particular to a device for manufacturing ultra-long flexible LED light sources. Background technique [0002] The linear flexible LED light source has the characteristics of arbitrary bending shape, high luminous efficiency and high brightness, and has become an energy-saving product that perfectly replaces the tungsten filament of the traditional incandescent lamp. The application of this kind of linear flexible LED light source in decorative lighting bulbs can bring users an excellent experience, especially in the North American and European Union markets where the demand for retro decorative lighting is strong. The basic process of the linear flexible LED light source is to first select the soft FPC as the base material, then set the rolled copper circuit on the surface of the FPC, fix the LED chip, coat the fluorescent glue, and finally bake and shape it into the final filament pro...

Problems solved by technology

The common length of this type of light source is 130mm, but as the demand for diversification in the market becomes more and more vigorous, the flexible LED light source with a length of 130mm is becoming more and more difficult to meet the demand. LED Light Source Demand

Due to the flexible characteristics of the substrate of flexible LED light source products, when the fluorescent glue is coated in the air, as the weight of the fluorescent glue increases, the flexible FPC substrate will sag under the weight of the fluorescent glue, resulting in the fluorescent glue not being evenly coated on the flexible surface. On FPC substrate

This sagging phenomenon increases with the length, the more obvious the sagging phenomenon, the more difficult the gluing process
