ASSEMBLING COMPONENTS ON A PRINTED CIRCUIT BOARD

摘要

Apparatus for and a method of assembling printed circuit boards. The apparatus comprises a microprocessing unit (1) which has a memory (2) in which the master layout of a printed circuit board is stored. A sensor head (5) is movable by mechanical moving means (6) controlled by the microprocessing unit (1). The sensor head (5) comprises a photosensitive array which provides signals to the microprocessing unit (1) to produce a digital representation of the target area. The microprocessing unit (1) then compares the representation with the image signal stored in its memory (2) to produce errors signals to cause the mechanical moving means (6) to move a component insertion device to the correct location. The apparatus may also be provided with a second memory (2') to store images of the patterns of components lead receiving apertures so that the microprocessing unit (1) can control a preforming unit (8) to preform the leads of component to fit the pattern of lead receiving apertures.
