Patent number: 6741055Abstract: There are provided a positioning-controlling apparatus and a positioning-controlling method in which a rotary encoder (2) detects the Z phase before the subject (4) is return to the origin which is the position of the Z phase detected by the linear encoder (5). The driving mode of the servo motor (1) is switched from rectangular waveform pulse driving to sine waveform pulse driving upon the detection of the Z phase by the rotary encoder (2). The subject's moving direction for returning to the origin may be previously specified, and in which the detection of the ON state of the origin sensor (11), the detection of the Z phase by the rotary encoder (2), and the detection of the Z phase by the linear encoder (5) are done in this order, while the subject (4) is being moved in the above specified direction. Alternatively, the rotary encoder (2) may detect the CS phase instead of the Z phase.Type: GrantFiled: December 26, 2001Date of Patent: May 25, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takahiro Kurokawa, Yoichi Tanaka, Seiichi Matsuo, Seishiro Yanachi

Patent number: 6694875Abstract: A screen printing method and apparatus for printing a circuit pattern corresponding to that of a stencil (4), onto a print-object article (1) placed on an ascendable/descendable positioning stage (2), through moving a squeegee (5a, 5b) horizontally while the squeegee is pushed in on the stencil so that print paste (9) is printed to the article via the stencil. The squeegee is lifted to an extent of a push-in stroke, to which the squeegee has been pushed in on the stencil, and thereafter the article is separated away from the stencil by moving the stage downward. The board is classified into first and second areas (121, 120) where values of opening sizes of the stencil along a squeegee moving direction are smaller than and not smaller than a threshold, and a speed of the squeegee at the first area is made slower than that at the second area.Type: GrantFiled: April 11, 2001Date of Patent: February 24, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Ken Takahashi, Naoichi Chikahisa, Yousuke Nagasawa, Takao Naito, Akihiko Wachi, Seishiro Yanachi, Nobuyasu Nagafuku, Nobuyuki Kakishima

Patent number: 6615110Abstract: A controlling method and apparatus for positioning a robot that can output an optimal speed instruction for controlling residual vibration after completion of a moving operation, achieve reduction in tact time for the moving operation, and shorten the length of setting time. The method is a controlling method for positioning a robot (1) for performing a point-to-point moving operation comprising: performing a test operation to measure a frequency of a residual vibration that is stopped at a target position; measuring a magnitude of the residual vibration based on the frequency during each of different lengths of moving time for a predetermined moving distance to find a relationship between the length of moving time and the magnitude of the vibration; calculating a shortest moving time at which vibration magnitude is minimized; and performing the point-to-point operation for the calculated shortest moving time, thereby to position the robot (1) at the target position.Type: GrantFiled: June 11, 2002Date of Patent: September 2, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Seiichi Matsuo, Youichi Tanaka, Takahiro Kurokawa, Seishiro Yanachi
