A component mounting system includes a component mounting device including a component mounting unit configured to mount a component on a substrate, and a controller, and a server configured to be communicable with the controller. The controller is configured or programmed to acquire a plurality of types of operating state changes that are likely to cause a quality defect, and to transmit, to the server, information according to the types of the operating state changes. The server is configured to provide information indicating an inspection type for the substrate based on the information according to the types of the operating state changes.

A manufacturing management device includes a determination section configured to determine the necessity of maintenance on any of the multiple production devices during production by the production line; and a conveyance management section configured to stop loading circuit boards, at a predetermined time, onto a reference device among the multiple production devices when it is determined that maintenance is necessary, the reference device being positioned upstream in the production line from a maintenance target device having a cause for maintenance.

A mounting head is configured to be detachably attached to a mounting device main body. This mounting head includes a storage section having multiple storage areas, and a storage control section configured to acquire multiple operation data relating to an operation of the mounting head individually at different timings and store the multiple operation data individually in the multiple storage areas in such a state that the mounting head is attached to the mounting device main body.

A rotary head, on which are arranged in a circumferential direction multiple nozzle holders each holding a suction nozzle, is provided with, separately to first negative pressure supply unit that supplies negative pressure to the suction openings of all the suction nozzles, second negative pressure supply unit that supplies negative pressure to the suction nozzle held by the nozzle holder that is lowerable when that nozzle holder is lowered. Accordingly, when performing pickup operation and mounting operation using the suction nozzle, the state of the suction nozzle is not affected by the state of the other suction nozzles.

A substrate work system including a work device configured to perform predetermined work on a substrate by use of an exchangeable work unit includes a storage section configured to store the work unit, a maintenance device configured to perform maintenance of the work unit, a conveyance device capable of conveying the work unit, a determination section configured to determine a maintenance time for the work unit used in the work device based on quality information on work quality of the predetermined work, and a control section configured to, when the determination section determines that a maintenance time arrives, cause the conveyance device, the work device, and the maintenance device to unload the work unit, convey the work unit to the work device to exchange with the work unit that has been used, and convey the used-up work unit to the maintenance device.

A component transfer device including: a component mounting tool mounted on a movable mounting head, the component mounting tool being configured to collect a component from a component supply device and mount the component on a board; a side imaging section configured to image the component held by the component mounting tool from the side; a cleaning nozzle having an emission port on a side surface only of the cleaning nozzle that opens toward the side imaging section; and a positive pressure air supply section configured to supply positive pressure air to the cleaning nozzle and blow out the positive pressure air from the emission port toward the side imaging section.

An equipment element repair management method for managing a repair operation of an equipment element that is attached to manufacturing equipment for manufacturing a product includes: performing a maintenance operation for the equipment element; determining whether or not a state of the equipment element after the maintenance operation is more improved than a predetermined state; transporting the equipment element of which the state is not more improved than the predetermined state to a repairer for performing the repair operation for the equipment element in a case where the state of the equipment element is not more improved than the predetermined state; and performing the repair operation of the transported equipment element in the repairer.

A management device for managing a component mounter that mounts components onto a substrate using some of constituent elements each selected from one of constituent element groups each including the constituent elements. One group is a nozzle group including nozzles. The device includes: a true displacement amount calculator that calculates, for each target component which is the component, a true amount of displacement which is a sum of (i) an amount of pickup displacement being an amount of displacement between the target component and a target nozzle being one of the nozzles and picks up the target component and (ii) an amount of correction being an amount of offset of a position of the target nozzle when picking up the target component; and a statistical processor that performs parameter estimation for a predetermined statistical model using the true amount to calculate a degree of malfunction of each constituent element.

A maintenance management device comprises: an inspection device configured to inspect an exchangeable element in a component mounting machine configured to mount a component on a circuit board; and an information management section configured to store statistical information in which results of multiple inspections with the inspection device are linked to identification information for each of multiple exchangeable elements targeted for inspection.

A work system includes multiple work devices aligned along a board conveyance line, a replenishing device having a sensor for detecting presence or absence of an interfering object and configured to move in parallel with the board conveyance line while detecting the presence or absence of the interfering object by the sensor to replenish necessary members to the multiple work devices, and a draw-out device configured to draw out at least one of the multiple work devices in a direction orthogonal to a direction along the board conveyance line. When a draw-out request for the work device is made, the replenishing device performs an automatic draw-out process of moving to a position in which a draw-out position of the work device to be pulled forward is included within a detection range of the sensor, so as to determine whether the interfering object is detected by the sensor.
