Substrate work system
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.
1. A substrate work system comprising:
a work device configured to perform predetermined work on a substrate using an exchangeable work unit of a plurality of work units, the work device being disposed on a work line;
a storage section configured to store the plurality of work units, the storage section being disposed separate from the work device and the work line;
a maintenance device configured to perform maintenance of the plurality of work units, the maintenance device being disposed separate from the work device and the work line;
an unmanned conveyance vehicle capable of conveying at least one work unit of the plurality of work units, the unmanned conveyance vehicle including a vehicle body section, wheels attached to the vehicle body section, and a loading table disposed on the vehicle body section; and
circuitry configured to automatically
determine an abnormality pre-indication state for a work unit that is being used by the work device based on quality information of the performed predetermined work, wherein the work unit that is being used by the work device does not cause an abnormality in the abnormality pre-indication state; and
when the work unit that is being used by the work device is in the abnormality pre-indication state, cause the unmanned conveyance vehicle, the work device, and the maintenance device to
unload a new work unit from the work units stored in the storage section for exchange,
convey the new work unit to the work device, for being exchanged with the work unit that was being used by the work device, and
convey the work unit that was being used by the work device to the maintenance device so as to be maintained thereby.
2. The substrate work system according to claim 1 ,
wherein the work device is a mounting device,
wherein the work unit is a feeder configured to supply a component and a nozzle configured to pick up the component and the nozzle further configured to perform, as the predetermined work, picking up the component supplied from the feeder and mounting the component that was picked up on the substrate,
wherein the maintenance device includes a feeder maintenance section configured to clean the feeder, and a nozzle maintenance section configured to clean the nozzle, and
wherein the circuitry is configured to determine the abnormality pre-indication state for the feeder and the nozzle based on state information on at least either of a suction state of the component and a mount state of the component, the state information on at least either of the suction state of the component and the mount state of the component being the quality information.
3. The substrate work system according to claim 1 ,
wherein the work device is a printing device,
wherein the work unit is a mask having an opening section formed therein and configured to perform, as the predetermined work, printing work of loading a viscous fluid into the opening section in the mask to thereby print the viscous fluid on to the substrate,
wherein the maintenance device includes a mask maintenance section configured to clean the mask, and
wherein the circuitry is configured to determine the abnormality pre-indication state for the mask based on a print state of the viscous fluid, the print state of the viscous fluid being the quality information.
4. A substrate work system comprising:
a work device configured to perform predetermined work on a substrate using an exchangeable work unit of a plurality of work units, the work device being disposed on a work line;
a storage section configured to store the plurality of work units, the storage section being disposed separate from the work device and the work line;
a maintenance device configured to perform maintenance of the plurality of work units, the maintenance device being disposed separate from the work device and the work line;
an unmanned conveyance vehicle capable of conveying at least one work unit of the plurality of work units, the unmanned conveyance vehicle including a vehicle body section, wheels attached to the vehicle body section, and a loading table disposed on the vehicle body section; and
circuitry configured to automatically
determine a periodical maintenance time for the work unit stored in the storage section when a length of time that the work unit has been stored in the storage section is greater than a predetermined time; and
when the periodical maintenance time has arrived, cause the unmanned conveyance vehicle to unload work unit stored in the storage section and convey the work unit that had been stored in the storage section to the maintenance device so as to be maintained thereby.
