摘要： PURPOSE:To enable the detection of a longitudinal bend of a lead pin, by setting a line to pass through the central part in the longitudinal direction of an image pattern of the lead pin, and by detecting the intersecting point of this line and the end part of the lead pin to determine the position of the intersecting point in the longitudinal direction. CONSTITUTION:A measuring line L is set on a prescribed position of an IC image picked up in an IC mounting device, and the brightness of image data D extracted along the line L shows a pattern as shown in a figure (b). Out of the image data, the data D of a part corresponding to the line L are averaged in a weighted manner to determine edge coordinates Xk of the opposite ends of each lead pin 2, and then the center coordinates of each pin 2 are determined. Then, a straight line S for sampling is set for each pin 2 through the center coordinates of the pin 2 and along the direction of the length thereof as shown in a figure (c). Since this straight line S intersects the fore end part of the pin 2 at a right angle, the brightness D of the image data are sampled along the straight line S and thereby the positions of coordinates in the direction of the length along the straight line S for sampling can be detected precisely. Subsequently, the positions of the coordinates of the fore end part of the detected pin 2 are compared for each pin 2, and thereby the amount of a longitudinal bend of the pin 2 can be detected.

摘要： PURPOSE:To facilitate accurate detection of a lead bend by a method wherein two measuring lines are provided for each lead bank of an IC respectively and a lead bend is detected through comparing plural one-dimensional images data sampled along these two lines. CONSTITUTION:A lead bend is detected depending on one-dimensional image data of an IC 1 to be inspected. In this process, two measuring lines, at least, are so provided as to traverse a lead bank in a lead bank-wise direction. An image data processing means, which samples one-dimensional image data from planar images picked up along these measuring lines L1 and L2, is provided and these plural one-dimensional image data are compared so as to detect each bend of the leads. By these processes, all manner of the lead bend including plural leads which are laterally bent as the whole can be easily detected in high speed and also with a high accuracy.

摘要： PURPOSE:To hold positioning accuracy constant by positioning any hole easily and securely regardless of the sizes of a variety of holes. CONSTITUTION:When an electronic component is inserted into a hole of a printed board 3 and assembled, the hole is positioned at an insertion position. At this time, luminous flux 2 is projected vertically by a projector 1 and when the board 3 is positioned temporarily, the luminous flux 2 passes through the hole 4. The board 3 is supported by being mounted on a table 5, which is operated horizontally by table driving motors 12 and 13 in an X and a Y direction to move in a direction crossing the optical axis 6 of the projector 1. Further, the holes is different in hole diameter for each board 3. Then, a detector 7 is installed opposite the projector 1 and when the board 3 is positioned temporarily, the detector outputs a voltage corresponding to the quantity of light photodetected through the hole 4 to detect the position shift in the center position of the hole 4. A controller 10 uses this data to position the center position of the hole 4 with the optical axis 6.

摘要： PURPOSE:To provide a head device for mounting an electronic component for an electronic component mounting machine which can sufficiently improve the positioning accuracy in mounting the component. CONSTITUTION:An electronic component holding member such as a suction nozzle 3 is mounted in the end 1A of a center shaft 1 by a piezo actuator 7, the actuator 7 is driven in response to a fine positional change between the nozzle 3 and the shaft 1 to cancel the deviation of the nozzle 3, thereby preventing its fine vibration. Since the fine vibration of the nozzle 3 is prevented, its mounting accuracy can be improved, and since the vibration generated at the time of accelerating/decelerating can be removed at the nozzle 3, its mounting time can be shortened.

摘要： PURPOSE:To eliminate the generation of defects and to improve a yield by analyzing the image data before parts are mounted on a circuit board printed with cream solder and deciding the normal/defective condition of the cream solder printing. CONSTITUTION:The images of the circuit patterns of the circuit board 12 are picked up by a TV camera 5 and the image data of the region of the circuit board 12 where the cream solder is presumed to be printed is taken into an image data analyzing section 7. The taken-in image data of the region of the circuit board 12 where the cream solder is presumed to be printed is investigated and the defect is detected from the degree of the presence or absence of the information indicating the presence of the circuit pattern therein. The ordinary operation to transfer the parts is started when the absence of the defect is decided. Then, the defective cream solder - printed circuit board having the high probability of generating the defect after the mounting of the parts is eliminated before the mounting of the parts and the high yield of production is maintained.

摘要： PURPOSE:To enable the center of deviation of mounting accuracy to be automati cally converged to an optimum position by analyzing an image data at a speci fied part by an image pick-up means for detecting the displacement of the position for mounting electronic parts and for controlling the mechanism of a robot. CONSTITUTION:The image of an actual mounting part of electronic parts, to be supplied from a parts supplying part 4, at a specified position of a printed- circuit board which is supplied from a printed-circuit board carrying part 3 by a cross robot mechanism 2 is picked up by TV cameras 5 and 6 of an elec tronic parts mounting device 1. This image pick-up data is analyzed by an image data analyzing part 7, the displacement of the position for mounting the electronic parts is detected, and the position of the electronic parts is corrected by the mechanism 2. With the configuration for achieving self- diagnosis control, the center of deviation of mounting accuracy can be converged to an optimum position and electronic parts having deviation can be mounted with improved accuracy.

摘要： PURPOSE: To maintain initial precision for a long period by making a self-diagnosis of an optical system, and altering conditions on which the center position of the hole is detected according to the diagnostic result.
CONSTITUTION: The hole 2d of a printed board 2c arranged at right angles to the optical axis T of spot luminous flux 2b emitted by a projection part 2a is irradiated with the spot luminous flux 2b. The output of the four-divided photodetecting element of a photodetection part 2g varies in proportion to the deviation of the hole 2d of the printed board 2c and its output is inputted to a microcomputer 2F through amplifying circuits 2AW2D and an A/D converter 2E. The microcomputer 2F calculates the quantity of correction and controls servo-motors 2H and 2J through a servo driving circuit 2G to align the insertion position of an electric insertion component to the hole center position of the printed board 2c. Further, the microcomputer 2F detects abnormality on the basis of the output of the photodetection part 2g in normal operation to alter the conditions of the center position detection of the hole.
