Voltage auto-compensation device for lamp strip detection and application thereof

Abstract

The invention discloses a voltage auto-compensation device for lamp strip detection, comprising a control mechanism, a length measuring mechanism, a voltage regulating power source and an operating panel. All the length measuring mechanism, the voltage regulating power source and the operating panel are connected with a control mechanism. The voltage auto-compensation device for lamp strip detection has the advantages that head voltage and tail voltage of a lamp strip under detection and length of the lamp strip under detection are set through the operating panel, voltage parameters for compensation are automatically calculated through the control mechanism, the control mechanism automatically adjusts voltage of the lamp strip detected and allows adaptation to an auto-detection system after the length of the LED lamp strip under detect is measured, detection is facilitated for the auto-detection system, error chances are decreased, and lamp strip detection smoothness and efficiency aregreatly improved; the device herein is suitable for the detection of monochromatic lamp strips, multi-color lamp strips and the like. An application method of the voltage auto-compensation device forlamp strip detection is also disclosed; the application method has simple steps and good operational convenience.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to an automatic voltage compensation device for lamp strip detection and its application. Background technique [0002] The light-emitting principle of the finished LED light strip is to emit light from the LED light beads evenly arranged on the flexible circuit board (FPCB board) at a certain distance. Because the LED light beads sometimes fail and do not emit light, after the finished LED light strip is made All checks are required. The current detection method is to use the CCD vision system to detect whether the LED lamp beads on the finished LED strip emit light. [0003] During the automatic detection process of the LED strip, due to the influence of the length, the strip has a certain voltage drop between the voltage at the head end and the end voltage after power-on (that is, the voltage at the head end is different from the voltage at the end), and the voltage difference...

Problems solved by technology

[0003] During the automatic detection process of the LED strip, due to the influence of the length, the strip has a certain voltage drop between the voltage at the head end and the end voltage after power-on (that is, the voltage at the head end is different from the voltage at the end), and the voltage difference causes the voltage drop on the LED strip The luminance of lamp beads will also change, especially for special types of light strips, such as colored lights, multi-color light strips, etc., which will easily cause false detection during the automatic detection process and affect the fluency of light strip detection and efficiency
