TECHNICAL FIELD

The present application is an electronic component mounting device configured to use a component tape in which multiple electronic components are accommodated at a predetermined pitch in a longitudinal direction, the electronic component mounting device performing static charge elimination on a used portion of the component tape from which the electronic components are taken out.

BACKGROUND ART

As an example of an electronic component mounting device, there is a component mounting machine in which electronic components are sequentially fed out using a component tape and electronic components taken out from the component tape are mounted on a circuit board. The supplying of electronic components is performed by a detachable component supply unit, and a tape feeder or the like can be used as such a component supply unit. In the tape feeder, a component tape, in which multiple electronic components are accommodated at a constant pitch, is wound around a supply reel, and the component tape is unwound from the supply reel by pitch feeding. Further, in the component tape, a cover tape is adhered to a carrier tape in which recessed accommodation portions are formed, and the electronic components are stored in the hermetically-sealed recessed accommodation portions.

The component tape easily becomes charged with static electricity, which may cause a problem during operation of the component mounting machine, Patent Literature 1 discloses an invention in which the problem of static electricity is addressed. Specifically, when the cover tape is peeled off the component tape charged with static electricity, the electronic components which should remain in the carrier tape adhere to the cover tape and are lifted. Therefore, in the conventional example of the literature, a configuration is adopted in which a static charge elimination brush is disposed in the tape introduction opening of the main body portion of the tape feeder, and the component tape fed out from the supply reel is subjected to static charge elimination by coming in contact with the static charge elimination brush at the introduction portion of the feeder main body portion.

BRIEF SUMMARY

Technical Problem

The component tape, however, also becomes charged at the component supply position of the tape feeder distal end to which the component tape is fed. This is because static electricity is generated by peeling off the cover tape from the carrier tape. Moreover, since the carrier tape is adhered to the cover tape by an adhesive, the adhesive remains on the surface from which the cover tape is peeled off. The used portion of the carrier tape from which the electronic components have been taken out (hereinafter referred to as “used carrier tape”) is collected in a collection box through a discharge duct for disposal but becomes attracted to the wall surface of the discharge duct by static electricity and sticks to the wall surface due to the adhesive remaining on the used carrier tape surface.

If the used carrier tape stops advancing in the discharge duct due to sticking to the wall surface, the portion to be subsequently fed becomes entangled, causing the inside of the discharge duct to become clogged. The used carrier tape, which has not managed to enter the discharge duct, then interferes with the suction nozzle in taking out electronic components. Therefore, the operator must take care not to let the used carrier tape dog the discharge duct, and if the used carrier tape clogs the discharge duct, the used carrier tape must be removed from the discharge duct. In addition, in order to remove the used carrier tape, the component mounting machine must be temporarily stopped, thereby delaying the manufacturing of electronic boards.

In order to solve this problem, an object of the present disclosure is to provide an electronic component mounting device that performs a static charge elimination process on a used portion of the component tape.

Solution to Problem

An electronic component mounting device according to an aspect of the present disclosure includes: a component tape in which a cover tape is adhered to a carrier tape accommodating multiple electronic components at a predetermined pitch; a tape feeder for feeding the component tape from a tape reel with having a peeling mechanism peeling the cover tape from the carrier tape at a component supply position; a mounting head configured to take out electronic components from the carrier tape at the component supply position and mount the electronic components on a board; and a tape collection portion in which a static charge elimination member is provided along a discharge path of the carrier tape from which the electronic components have been taken out, the discharge path being through a discharge duct from the tape feeder to a collection box.

Advantageous Effects

With the above configuration, since the static charge elimination member is provided in the tape collection portion, and the used portion of the carrier tape, from which the electronic components have been taken out, is neutralized while being discharged, it is possible to prevent the used portion of the carrier tape from becoming attracted to the discharge duct by static electricity when the carrier tape is fed from the tape feeder to the collection box through the discharge duct.
