摘要:
A positioning data correction apparatus with image analyzing, for producing a corrective positioning command used in a positioning device for positioning a tool along an axis with respect to a target on a work in response to a command, comprises: a receiver for receiving the command and a mode signal; a camera connected to the tool for producing an image signal with respect to the axis in response to light from the work; an image analyzer responsive to a control signal and to the image signal for detecting a position of the target by analyzing a pattern along the axis and for producing corrected positioning data by obtaining deviation of the position along the axis from a given point within an angle of field of the camera; and a controller responsive to the mode signal, the received command, and the corrected positioning, the controller operating: sending the received command to the positioning device; and for producing the control signal to case the image analyzer to product the corrected positioning data and producing the corrective positioning command in accordance with the corrected data in the presence of the external control signal.
摘要:
Unique circuit location sensing apparatus for component placement robots (100) utilizes a high-resolution optical reflective sensor (110) for detecting the location of selected circuit runners (300, 301) on a printed circuit board (350). The sensor (110) is mounted to the robot arm (106) and coupled by A/D converting circuitry (104) to the robot computer (102). The robot computer (102) positions sensor (110) over a selected runner (300, 301) and steps sensor (110) across the selected runner (300, 301), storing the digitized sensor output for each step. The robot computer (102) processes the digitized sensor outputs to determine the actual location of the selected runner (300, 301) and then calculates location offsets for the component placement program to be subsequently run on the robot computer (102). As a result, variations in actual location of circuitry on different printed circuit boards (350) are automatically compensated for and components are more accurately placed thereon. The unique circuit location sensing apparatus of the present invention may be advantageously utilized in any component placement robot for accurately detecting the location of circuitry prior to placement of components on the printed circuit board.
