Patent ID: 8111899

Claim:
A substrate-check equipment comprising: a frame; a conveyer mounted through the frame and having an upper surface and an lower surface and being adapted to convey a substrate; at least two lamps mounted pivotally on the frame using mounting brackets and respectively above the upper surface of the conveyer and below the lower surface of the conveyer to respectively shine light onto the upper and lower surfaces of the conveyer and each of the at least two lamps having an adjusting unit for adjusting intensity of light emitted from the lamp; at least two image acquisition units corresponding to the lamps and being mounted pivotally on the frame using mounting brackets and respectively above the upper surface of the conveyer and below the lower surface of the conveyer to respectively acquire images of a substrate and generating image signals; a control unit being connected electronically to the lamps and the image acquisition units to control the adjusting unit of each lamp to emit light with a specific intensity and receiving image signals from the image acquisition units; and at least two actuators being mounted on the frame, controlled by the control unit corresponding to the lamps and the image acquisition units and being connected electronically to the mounting brackets to control the lamps and the image acquisition units to pivot relative to the substrate to required angles.
