PCB patch spring structure and assembling mode

Abstract

The invention discloses a PCB patch spring structure and an assembling mode. The PCB patch spring structure comprises a PCB, a spring and a patch. A spring mounting area is arranged on the surface ofthe PCB; the spring is arranged in the spring mounting area on the surface of the PCB; a pin is arranged at the bottom of the spring, specifically the pins is a flat pin, the flat pin is flush with the bottom of the spring. A metal face corresponding to the flat pin is arranged on the surface of the PCB. When the spring is installed on the PCB, the flat pin is tightly attached to the metal face ofthe PCB, and the patchis attached to the top of the spring. According to the scheme, the vertical pin of a common plug-in spring is designed into the flat pin and combined with the high-temperature-resistant patch to form a patch spring finished product. A chip mounter is used for identifying the patch on the top of the spring, the spring is correspondingly and automatically placed on the PCB andthen the flat pin on the spring and the metal sace on the PCB are welded together through solder paste so that the whole spring assembling process of the PCB is fully automatic, efficient and rapid,and a large amount of manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the technical field of PCB assembly springs, and in particular relates to a PCB patch spring structure and an assembly method. Background technique [0002] Assembling springs on PCB boards is a common process in the electronics manufacturing industry. Traditional PCB board assembly springs use springs with vertical pins. The specific process is: first punch a hole on the PCB board, and then manually Insert the vertical pins at the bottom of the spring into the holes opened on the PCB board, and finally fix the pins and the PCB board together by welding on the back of the PCB board; this assembly method has many defects: it requires a lot of labor, PCB drilling, spring installation, and final pin welding all require different operators to operate, and the entire assembly time is also very slow, which affects work efficiency; drilling holes on the PCB board is easy to damage the PCB board, causing unnecessary damage. Necessary ...
