Patent number: 10292319Abstract: Before using a load cell to measure a load (nozzle load) arising during relative movement between a suction tube and a pipe of a suction nozzle, the suction nozzle and a metal contact tool are moved towards each other by a set load with the metal contact tool contacting the tip section of the suction tube. When the suction tube and the pipe has moved relatively by set amount due to the suction nozzle and metal contact tool being moved towards each other, the nozzle load of the suction nozzle is measured using the load cell. Nozzle load is measured only for a suction nozzle for which relative movement of the suction tube and the pipe has been confirmed, and nozzle load is measured appropriately without damaging the load sensor.Type: GrantFiled: April 22, 2014Date of Patent: May 14, 2019Assignee: FUJI CORPORATIONInventors: Kazumi Hoshikawa, Kenji Shimosaka, Tadakatsu Ibe

Publication number: 20180263152Abstract: When performing inspection of a tip of a suction nozzle, the tip of the suction nozzle is imaged, and an opening of the tip of the suction nozzle is identified based on the image data. With the image based on the image data, locations with less than a set brightness level inside a location with the set brightness level and greater is identified as the opening. The identified opening is divided into four regions by boundary lines, and the area of the opening is calculated for each of the regions. Based on the areas calculated for each region, it is determined whether the suction nozzle is good. By determining whether the suction nozzle is good based on the area of the opening for each region, it is possible to reliably determine whether the suction nozzle is good.Type: ApplicationFiled: September 15, 2015Publication date: September 13, 2018Applicant: FUJI MACHINE MFG.

Publication number: 20170120459Abstract: An inspection method of a suction nozzle. Air flow rates that flow in multiple reference pipes that have different sectional areas are measured. A proportionality factor between air flow rates and sectional areas of the reference pipes is calculated based on the measured air flow rates of the multiple reference pipes, and the sectional areas of the multiple reference pipes. An air flow rate in a suction nozzle that is an inspection target is measured. The sectional area of the suction nozzle is calculated based on the air flow rate of the suction nozzle and the calculated proportionality factor. The sectional area of the suction nozzle calculated in this manner is substantially fixed even when the pressure of air supplied from an air source fluctuates. The sectional area of the suction nozzle is proportional to the air flow rate that flows in an inner portion of the suction nozzle.Type: ApplicationFiled: July 15, 2014Publication date: May 4, 2017Applicant: FUJI MACHINE MFG.

Publication number: 20170036247Abstract: A nozzle cleaning device for cleaning suction nozzle 62, wherein the jetting direction of water jetted towards the tip section of the suction nozzle is changed by a tapered second internal surface 374 of socket 370. Accordingly, for example, not only is it possible to appropriately remove items adhering to the lower surface of the tip of the suction nozzle, it is possible to remove items adhering to the side surfaces of the tip of the suction nozzle by applying water. The suction nozzle is cleaned while being supported by nozzle pallet 152; after the suction nozzle is cleaned, the suction nozzle is held by a holding tool and removed from the nozzle pallet.

Patent number: 8588510Abstract: When a detection-target subject is imaged with an image pickup device having line-defect pixels, the detection-target subject is imaged, with the image pickup device or the detection-target subject rotated at a predetermined angle so that the edge of one side of the detection-target subject is not parallel to each of horizontal and vertical scanning lines of the image pickup device, and a gray-scale image is captured by a control apparatus. In the gray-scale image, the luminance of each of the line-defect pixels is corrected by interpolation with luminances of pixels adjacent to both sides of the line-defect pixel. The gray-scale image is subjected to sub-pixel processing to detect the edge of the detection-target subject. When the detection-target subject is a component in a rectangular shape, rotation is made so that four sides are not parallel to each of the horizontal and vertical scanning lines of the image pickup device.Type: GrantFiled: September 21, 2011Date of Patent: November 19, 2013Assignee: Fuji Machine Mfg.
