Automatic taking-out device for PCB positioning pin

The automatic taking-out device for the PCB positioning pin comprises a base, a through hole matched with the positioning pin in size is formed in the base, a fixing support is arranged at the top ofthe base, an air cylinder is installed on the fixing support, a piston rod of the air cylinder is perpendicular to the top face of the base, an ejector pin is installed at the end of the piston rod, and the ejector pin is right opposite to the through hole. A through hole is formed in the base, a cavity is formed in the base, a material sensor used for detecting a positioning pin inserted into thethrough hole is installed in the cavity and located beside the through hole, the material sensor is in signal connection with an air cylinder controller, and when the material sensor detects the positioning pin, the air cylinder acts to enable the ejector pin to downwards eject out the positioning pin on the plate face. The positioning pin can be automatically taken out, can be repeatedly used and is convenient to operate
