Work management device

A work management device that manages an electronic component mounting line with a plurality of mounting machines mounting electronic components on a board, the work management device comprising:

• an operator information memory section that stores operator information regarding a plurality of operators working in the electronic component mounting line;
• a work item memory section that stores a work item group performed by the plurality of operators in the electronic component mounting line;
• a plurality of operator detection sections that are installed at a plurality of spots of the electronic component mounting line, the plurality of operator detection sections including a face detecting camera configured to image a face of an operator of the plurality of operators;
• and
• a work instruction section that instructs one operator among the plurality of operators to work a work item selected from the work item memory section, the work instruction section including a display,
• wherein an operator detection section of the plurality of operator detection sections detects the operator located near a spot at which the operator detection section is installed by comparing an image captured by the face detecting camera to the operator information,
• wherein in a case in which the operator detection section detects the operator, and the work item group stored in the work item memory section includes the one work item or a plurality of work items to be performed by the operator detected by the operator detection section, the work instruction section instructs the operator detected by the operator detection section to perform at least one of the work items selected from the one work item or the plurality of work items,
• wherein the work items of the work item groups are ranked in accordance with degrees of difficulty of the work items,
• wherein the operator information includes the degrees of difficulty of the work items which are able to be performed by the plurality of operators,
• wherein the work item memory section stores the work items in association with the degrees of difficulty,
• wherein in a case in which the operator detection section detects the operator, and the work item group stored in the work item memory section includes the one work item or the plurality of work items associated with the degrees of difficulty equal to or lower than the degrees of difficulty ranked for the operator detected by the operator detection section, the work instruction section instructs the operator detected by the operator detection section in the one work item or the plurality of work items selected from the one work item or the plurality of work items,
• wherein the plurality of mounting machines are configured to detect end of work items in the work item groups and transmit the end of the work item and the degrees of difficulty of the work items performed by the operator to the work management device, and
• wherein the work management device further comprises an updating section that deletes the work item from the work item memory section and updates the work item group, in a case in which the end of the work item is received from the mounting machine, when the work items are worked by the operator ranked with the degree of difficulty or more in which the work items are able to be performed, and conversely does not delete the work item from the work item memory section when the work item is worked by the operator ranked with the degree of difficulty lower than the degree of difficulty in which the work item is able to be performed.
