Patent number: 7533459Abstract: The invention is directed to increased stabilization of a pickup operation by reducing a reaction against disturbance by reducing a feedback value when a pickup rate is improved. A positional shifting amount of an electronic component on a suction nozzle before the electronic component is mounted on a printed board is stored in a RAM each time the component is picked up at a component feeding unit until a pickup count number reaches a predetermined pickup number, and a CPU calculates an average of the positional shifting amounts. When the pickup count number reaches the predetermined pickup number, the CPU obtains a temporary coefficient by adding an initial value to a value obtained by multiplying a negative coefficient by the pickup count number, and calculates a feedback value by multiplying the temporary coefficient by the average.Type: GrantFiled: April 25, 2005Date of Patent: May 19, 2009Assignee: Hitachi High-Tech Instruments, Co., Ltd.Inventors: Yoshinori Kano, Takeshi Tomifuku, Yoshinori Okamoto, Yoshinao Usui, Ikuo Takemura

Patent number: 7296343Abstract: An electronic component mounting apparatus enables a reliable decision of abnormal suction of a component even when the difference between the width and the height of the component is small. When the difference between the thickness of the electronic component detected by a sensor and the data on the thickness stored in the RAM is within the tolerance, a CPU judges that the component is held by a suction nozzle in a normal posture and executes a normal processing control. Then an image of the electronic component is captured by a recognition camera, and a recognition processing is made by an image processing unit to measure the geometry of the component. The CPU, then, judges whether the size of the component is within tolerance or not.Type: GrantFiled: September 30, 2002Date of Patent: November 20, 2007Assignees: Sanyo Electric Co., Ltd., Sanyo High Technology Co., Ltd.Inventors: Yoshinao Usui, Akihiro Kawai, Manabu Okamoto
