Positioning fixture for assembling flexible printing circuit (FPC)

The invention belongs to the fixture field used in processing procedures of electronic products, and in particular relates to a positioning fixture for assembling a flexible printing circuit (FPC). The fixture comprises a layer of bottom plate, a layer of FPC carrier plate arranged on the bottom plate, a product positioning pin and a carrier plate positioning pin, wherein the product positioning pin and the carrier plate positioning pin vertically penetrate through the FPC carrier plate and are inserted into the bottom plate. The fixture is characterized in that a thin steel sheet is also arranged between the bottom plate and the FPC carrier plate and provided with holes so that the product positioning pin and the carrier plate positioning pin can pass through, the product positioning pinand the carrier plate positioning pin are tightly clamped by the thin steel sheet through the holes so that shaking is not generated, and the thin steel sheet is also provided with a layer of bonnet lock pressing plate used for pressing the thin steel sheet tightly. The fixture can reduce the possibility of deviation caused in the assembling process, is convenient for assembling, improves the assembling precision of the FPC and provides the accurate positioning for subsequent processing procedures of the FPC.
