Device for attaching flexible circuit board to concave workpiece

The utility model relates to the field of tools, in particular to a device for fitting a flexible circuit board on an indent workpiece, which comprises a support jig, a flexible circuit board, a pressing plate, a pressing plate, a pressing plate, a pressing plate, a pressing plate, a pressing plate, a pressing plate and a pressing plate, and is characterized in that the support jig is provided with a plate groove; the inner concave workpiece fixing die is provided with a workpiece groove, and the workpiece groove is used for placing an inner concave workpiece; the face, provided with the plate groove, of the supporting jig is opposite to the workpiece groove. The supporting jig is inserted into the inwards-concave workpiece, so that the flexible circuit board is attached to the inwards-concave curved surface of the inwards-concave workpiece. According to the invention, the flexible circuit board is clamped and placed on the supporting jig by using the clamp, and then the concave workpiece fixing die with the
