Dust removal system for led strip and appratus with the dust removal system

Abstract

A apparatus for treating an LED strip includes a warming zone, a dust removal system disposed in the warming zone, a belt transporting the LED strip through the dust removal system, a high temperature zone and a cooling zone. The dust removal system includes an airflow generating device producing an airflow removing dust away from the LED strip when the LED strip passes through the airflow generating. The high temperature zone performs a reflow soldering to the LED strip which has a plurality of LEDs mounted thereon.

         9 . The dust removal system of  claim 8 , wherein the lower airflow generating device comprises an electrostatic eliminating bar located at a middle of a top end of the sucking port. 
     
     
         10 . The dust removal system of  claim 9 , wherein the lower airflow generating device comprises a brush near the top end of the sucking port. 
     
     
         11 . A apparatus for treating an LED strip, comprising:
 a warming zone;   a dust removal system disposed in the warming zone;   a belt transporting the LED strip through the dust removal system; wherein the dust removal system comprises an airflow generating device producing an airflow removing dust away from the LED strip when the LED strip passes through the airflow generating.   
     
     
         12 . The apparatus of  claim 11 , further comprising a high temperature zone and a cooling zone, wherein the LED strip is transported by the belt to sequentially pass through the dust removal system in the warming zone, the high temperature zone and the cooling zone. 
     
     
         13 . The apparatus of  claim 11 , wherein the temperature of the warming zone is lower than 100° C., and the LED strip being dried when the LED strip passes through the warming zone. 
     
     
         14 . The apparatus of  claim 11 , wherein the LED strip is reflowed when the LED strip passes through the high temperature zone. 
     
     
         15 . The apparatus of  claim 11 , wherein the airflow generating device comprises an upper airflow generating device and a lower airflow generating device, the LED strip passing through a space between the upper airflow generating device and the lower airflow generating device of the dust removal system. 
     
     
         16 . The apparatus of  claim 15 , wherein the upper airflow generating device comprises a blowing port blowing the air flow to the LED strip.
