Publication number: 20110162202Abstract: An object of the invention is to provide an electronic component mounting device and a work method of the electronic component mounting device, capable of ensuring safety of an operator who accesses a work line through a door portion, and avoiding reduction of workability. A space defined by a base (11) and a cover member (14) is partitioned by a partition member (15) to define a plurality of work line storing spaces (SP1). A plurality of work lines (12) are stored in the respective work line storing spaces (SP1) individually. When any of a plurality of door portions (14a) provided in the cover member (14) so as to allow an access to an inside of the respective work line storing spaces (SP1) is opened, an operation of a work line (12) stored in a work line storing space (SP1) accessible through the opened door portion (14a) is stopped.Type: ApplicationFiled: June 23, 2009Publication date: July 7, 2011Applicant: PANASONIC CORPORATIONInventors: Seiichi Miyahara, Nobuhiro Nakai, Minoru Murakami, Takahiro Fukagawa, Takashi Yazawa, Kimiyuki Yamasaki

Patent number: 7367115Abstract: A component mounting apparatus having a work conveyor-positioner unit is arranged on a supporting base to convey and position a substrate in an X direction. Supporting frames extend vertically from ends of the supporting base and face each other in a Y direction. The component mounting apparatus further includes a plurality of Y-axis tables extending between upper ends of the supporting frames, X-axis tables attached to movable portions of the Y-axis tables, and operating heads attached to movable portions of the X-axis tables to perform operations with respect to the substrate on the work conveyor-positioner unit. Each of the plurality of the Y-axis tables includes a movable portion at a lower part. Each of the X-axis tables includes a movable portion at a lower part and the operating heads are attached to a lower part of the movable portion of the X-axis tables.Type: GrantFiled: December 4, 2003Date of Patent: May 6, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Nobuhiro Nakai, Hiroshi Ota, Kensuke Kawasumi, Hirotsugu Uemori, Kimio Iizuka
