摘要： A flashlamp circuit includes a charge reservoir that receives a first voltage from an external source. The charge reservoir is coupled to a resonator and a plurality of discharge capacitors to provide a second voltage to the plurality of discharge capacitors that is greater than the first voltage. A switch is disposed between at least one of the discharge capacitors and ground to selectively charge the at least one discharge capacitor based upon an input to the switch. Discharge energy is passed from the discharge capacitor(s) to a flashlamp through a discharge bank without passing through any inductive elements. A bleeder circuit can be interposed between the power supply and the reservoir to discharge the reservoir upon shutdown.

摘要： The present invention is a light based detection system for providing a low cost, very fast and very accurate measurements of lead positions and heights for integrated circuit board components. The alignment detections systems of the present invention are preferably located on a component placement head. The detector is a linear or rectangular array of pixels. The light path between the light source and the detector array is directed by the optical components across one or more leads in a plane that is neither parallel to nor perpendicular to the seating plane of the component. The light path is directed across the relevant leads without substantial interference from the body of the component or the other leads not being measured. A digital processor analyzes the measurements of the light sensitive detector to determine positions and/or coplanarity of the leads.

摘要： High speed high precision alignment sensor systems for use on surface mount component placement machines. Light systems are used to correctly align and position component parts. The sensor system consists of a light source and an optical lens system causing more of the light from a light source to pass the component in order to obtain a sharper component image on a sensor array. Due to the optical lens systems disclosed, either low powered lasers, light emitting diodes, or other suitable light sources can be used in the system since optical efficiency is substantially increased over prior systems since more of the radiated light is collected from the light source for measurement at the detector. The sensor system is mounted directly on the carrying mechanism for the surface mount component placement machine. During transit of the component between the bin of components and the circuit board upon which the component is to be placed, the component is rotated and the sharp shadow which falls on the detector array is monitored. Several processing algorithms are disclosed for determining correct component angular orientation and coordinate (X,Y) location of the component on the quill. Thereafter, the sensor sends correcting signals to the component placement machine.

摘要： Methods and apparatus for improving the efficiency of using optical sensors with component placement machines for the placement of components onto a circuit board. One of the improved methods involves the placement of a projection or notch at a selected position on the quill. The projection or notch is detected by the light based component sensor system on the placement head to indicate that it is safe to begin moving the placement head. A second improved method uses a constant, high angular velocity to rotate the component when the sensor is using the shadow cast by the body of the component to align the component. The use of a constant angular velocity allows for the correction for the rotation in determining the orientation to give very accurate results even though the velocity is relatively high. In a further improvement, the information used to determine the position of the component on the quill is used to calculate the dimensions of the component for comparison with expected dimensions of the component. Also, measurements taken without a component in the light path can be used to monitor the condition of the sensor to determine if maintenance is required or recommended.
