An allowable value setting device sets an allowable value of a deviation amount between a target pickup position and an actual pickup position in a component when the component is picked up by a suction nozzle. The allowable value setting device includes a first setting section and a second setting section. The first setting section sets a first allowable value, which is the allowable value for each component type of the component to be mounted on a board. The second setting section sets a second allowable value, which is the allowable value that is set for each mounting coordinate of the component and smaller than the first allowable value of the component of the same component type set by the first setting section, the second allowable value being preferentially adopted over the first allowable value in a suction process of the component.

Provided is a method for operating an electronic component mounting system including component storages including a dry box. The method includes maintaining a material management table including a whereabouts information field for indicating whether an electronic component is stored in the dry box, a target indicator field for indicating whether an electronic component is a moisture management target component, and an exposure time field for indicating an exposure time during the moisture management target component has been in an atmospheric exposure state. The method also includes pausing counting the exposure time when the moisture management target component is stored in the dry box, identifying a moisture management target component of which the exposure time has met or exceeded an exposure limit time based on the whereabouts information table, and notifying the identified moisture management target component to an apparatus.

A parts replenishment system configured to replenish a parts supply device attached to a parts mounting device with parts includes an instruction device configured to issue an instruction to unload the parts from a storage. The parts replenishment system further includes a presentation device configured to present preprocessing identification information for identifying preprocessing, which is processing on a packaging material for the parts for which an unloading instruction has been issued by the instruction device before replenishment of the parts supply device with the parts.

A system and method for surface mount assembly of PCB's, using an automated pick-and-place machine into which component tapes on reels are fed, uses component tape reels each of which has been pre-threaded into its appropriate tape guide and been stored as a reel/tape guide packet in an automated SMD storage tower, from which appropriate packets are retrieved for coupling to the pick-and-place machine.

A feeder includes a sprocket that feeds a tape accommodating multiple components; a motor that rotates the sprocket; a storage section to store the rotational position of the sprocket detected by a sensor as an initial rotational position when the tape is set in the feeder and store a cumulative feeding amount of the tape fed by the rotation of the sprocket; and a control section to control the motor such that the sprocket rotates in a forward direction based on a feeding amount of the tape required for a supply when supplying the components to the component mounting machine, and control the motor such that the sprocket does not rotate in a reverse direction in excess of the initial rotational position based on the initial rotational position and the cumulative feeding amount when rewinding the tape.

A device for inspecting a suction nozzle includes an imaging device configured to acquire an image by imaging a flange portion of a suction nozzle having a body cylinder and the flange portion protruding from an outer surface of the body cylinder, and a control device configured to execute an inspection process for determining whether the flange portion is defective based on the image.

A component mounting system including multiple component mounting devices to collect components from feeders set at multiple feeder holding sections and mount the components on a board, the multiple feeder holding sections being provided on each of the multiple component mounting devices to removably hold the feeders; and a feeder exchanging device to move along a line along which the multiple component mounting devices are arranged and exchange feeders with respect to each of the component mounting devices. The component mounting system acquires a type and arrangement of each of the feeders set on the multiple component mounting devices, determines whether each of the feeders is set at a predetermined appropriate position, and upon determining that there is a feeder that is not set at the appropriate position, uses the feeder exchanging device to reset the feeder that is not set at the appropriate position.

A management device includes a management control section configured to create rearrangement disposition information for rearranging recovery feeders in a recovery storage region and rearranging provision feeders in a provision storage region among feeders temporarily stored in a storage section by using storage position information regarding storage positions of the provision feeders and the recovery feeders temporarily stored in the storage section and region information including the recovery storage region and the provision storage region set in the storage section, and output the created rearrangement disposition information.

The method includes maintaining a material management table including a whereabouts information field for indicating whether an electronic component is stored in the dry box, a target indicator field for indicating whether an electronic component is a moisture management target component, and an exposure time field for indicating an exposure time during the moisture management target component has been in an atmospheric exposure state. The method also includes pausing counting the exposure time when the moisture management target component is stored in the dry box, identifying a moisture management target component of which the exposure time has met or exceeded an exposure limit time based on the whereabouts information table, and notifying the identified moisture management target component to an apparatus.

A component mounter includes a substrate conveying-and-holding device 22 configured to convey a board, work heads 60, 62 configured to hold a component, a work head moving device 64 configured to shift the work heads above the board, multiple work units 34, 36, 37 configured to perform work on the board from below, and a unit moving device 35 configured to shift the work units below the board, and each of the multiple work units is mounted on a mounting section of the unit moving device in an exchangeable fashion. With the substrate work machine configured as described above, the board can be worked on from above and below, hence making it possible to deal with various types of work. In addition, by exchanging the work units mounted in the mounting section, further types of work can be dealt with.
