Description

Inventory management device, inventory management system, inventory management method, and program

The present invention relates to an inventory management device, an inventory management system, an inventory management method, and a program that support a component replenishment operation.

As electronic products become smaller and more multifunctional, a method of arranging chip-type electronic components on a printed circuit board is used in many products. In general, in an electronic component mounting apparatus in which electronic components are arranged on an electronic circuit board, a reel around which the electronic components are wound at a predetermined interval is mounted on a tape feeder having a tape feeding mechanism, and the tape is attached. Electronic parts are supplied by sending.

The electronic component replenishment method includes stopping the electronic component mounting device and mounting a new reel on the tape feeder, and joining the new reel tape while the electronic component mounting device is in operation, and removing the electronic component without interruption. There is a way to replenish. When replenishing with the former method, it is necessary to stop the electronic component mounting apparatus, so that the operating rate of the electronic component mounting apparatus is lowered. In the case of replenishment by the latter method, since the replenishment can be performed while the operation of the apparatus is continued, the operation rate of the electronic component mounting apparatus does not decrease. However, if the replenishment timing in the latter method is wrong, the electronic component mounting apparatus stops. For this reason, in order to suppress a reduction in the operating rate of the electronic component mounting apparatus, timely replenishment of electronic components by the latter method is indispensable. Therefore, a technique for predicting the replenishment timing of the electronic component from the remaining number of electronic components and preventing an error in the replenishment timing has been developed.

In Patent Document 1, the number of remaining parts is calculated by sequentially subtracting the number of parts that are reduced by the repetition of the part picking operation of the electronic part mounting apparatus, and the part replenishment operation that requires parts replenishment work based on the number of remaining parts An electronic component mounting apparatus that predicts timing and displays a code indicating component supply timing is disclosed.

In Patent Document 2, when the number of parts used is calculated by detecting the parts continuously carried out from the parts storage box with a sensor, and the number of parts used after subtracting the number of parts used becomes equal to the warning value A used component management apparatus that outputs a warning signal to an external interface is disclosed.

In Patent Document 3, the number of parts used is calculated in accordance with an extraction detection signal input every time a part is taken out, and the time until each part runs out of parts is calculated based on the number of parts remaining after subtracting the number of parts used. There is disclosed a component supply device that calculates and notifies that a component has run out.

In the technique described in Patent Document 1, since the electronic component mounting apparatus includes a control device that calculates the component supply timing and displays the component supply timing on the tape feeder, it is necessary to replace existing equipment, which increases costs. To do.

In the technology described in Patent Document 2, a recording medium for recording data indicating the remaining number of parts is provided in a parts storage box of a parts cassette that feeds out a tape with parts attached thereto, and a device that reads the recording medium in the parts cassette, Since the sensor is provided with a sensor for detecting parts that are continuously carried out from the storage box, it is necessary to replace existing equipment, which increases costs.

Each time the detection signal acquisition unit acquires a detection signal, the component remaining number calculation unit calculates the electronic component mounted on the single electronic circuit board from the number of electronic components held by the electronic component mounting device. The number of components is subtracted to calculate the remaining number of electronic components held by the electronic component mounting apparatus, and the time from the remaining number of electronic components to the replenishment timing of the electronic components is calculated. When there is an electronic component mounting apparatus in which the time until the electronic component replenishment timing calculated by the remaining component calculation unit is equal to or less than the threshold, the electronic component mounting with the time until the electronic component replenishment timing is equal to or less than the threshold Replenishment instruction information for instructing replenishment of electronic parts of the apparatus is generated. The replenishment instruction output unit outputs replenishment instruction information.

According to the present invention, the inventory management device independent of the electronic component mounting apparatus calculates the time until the electronic component replenishment timing, and performs the electronic component replenishment operation of the electronic component mounting apparatus whose time until the replenishment timing is equal to or less than the threshold value. By instructing the operator, it is not necessary to replace existing equipment, and an error in the replenishment timing of the electronic components of the electronic component mounting apparatus can be prevented at low cost.
