The system includes an array of cameras configured to acquire a plurality of sets of images as the substrate and the array undergo relative motion with respect to each other. At least one focus actuator is operably coupled to each camera of the array of cameras to cause displacement of at least a portion of each camera that affects focus. A substrate range calculator is configured to receive at least portions of images from the array and to calculate range between the array of cameras and the substrate. A controller is coupled to the array of cameras and to the range calculator. The controller is configured to provide a control signal to each of the at least one focus actuator to adaptively focus each camera of the array during the relative motion.

摘要： A laser based, noncontacting measurement instrument is particularly adapted for the printed circuit board drilling industry to measure drill diameter, runout, and tip position under actual operating conditions. A laser beam is focused in space and the amount of light occluded by the drill bit as the bit is passed through the beam is sensed by a detector. Diameter, runout, and tip position are calculated by measuring the amount of occlusion, monitoring the position and angular orientation of the rotating drill, and correlating the amount of light occlusion to the position and angular orientation of the drill. The instrument automatically compensates for dust and debris in the optical path.

摘要： Methods and an apparatus are disclosed for providing enhanced vibration immunity in a solder paste inspection system, although they are usable in any number of industries that require rapid acquisition of several images. The method includes capturing at least three images on a frame transfer CCD array before any data is sequentially read from the array. The present method is extendable to a larger number of images. Additionally, the masked memory area can be larger than the image area of the frame transfer CCD array.

摘要： A laser based noncontact detection system is disclosed which is useful in automated manufacturing. The sensor system detects the presence or absence of an object that is either rotating or in some other continuous repetitive motion such as a rotating drill bit. This device is especially useful for detecting broken or absent drill bits used for drilling printed circuit boards. The system projects a laser beam onto the concave face of the flute near the tip of a drill bit and the amount of light which is reflected by the drill bit is sensed by a detector. The sensor is located at an angle oblique to the axis of rotation. Due to the rotation of the drill bit, fluctuating electronic signals are produced, detected and analyzed to determine the presence of the drill bit. The system automatically compensates for dust, debris and ambient light. Sensor positioning allows for greater drilling machine throughput since there is no need to fully retract the drill bit for breakage or damage detection. The laser beam may be focused into a stripe of light allowing for the detection of rotating drills of differing diameters without refocusing the light source when the sensor is used on a drilling machine using different and interchangeable drill sizes. The system can be used for detecting any continuously revolving object or any object in any other continuous repetitive motion. The presence of the object may be verified after each repetitive motion sequence.

摘要： A high speed, high precision laser-based semiconductor lead measurement system for use on surface mount component placement machines. A multi-beam laser system is used to accurately sense the position and condition of each of the many leads used on integrated circuits prior to their placement on a surface mount circuit board by a pick and place machine. Using two, three or four laser beams, the non-contact sensor system can, with the highest degree of resolution, determine lateral orientation, height, colinearity, and coplanarity of leads for integrated circuit components, even those having an ultra-fine pitch. Determination of the lead position by the invention is based on the integrated circuit leads occluding the light of one or more precisely directed and focused laser light sources. Each integrated circuit lead is passed nominally through the focal point of a laser beam. The position of each lead is determined when it blocks all or a portion of the light of the laser beam. A processor means is used to calculate the actual position of each lead. The difference between the actual position of the lead and the nominal position of the lead can then be computed. The position of each lead is then sorted to determine the greatest deviation of any lead from a best fit line or from the Seating Plane. The processor may then either generate a reject or a repositioning signal to the component placement machine for proper placement of the integrated circuit upon the surface mount circuit board.
