Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a taped component supply device that conveys a plurality of components attached to a tape to a predetermined position on a tape conveyance path.

[Conventional technology]

Generally, this kind of taping parts supply device.

When assembling electronic components using an automatic assembly machine, there are 6 tapes configured such that 4 feeding means transport the tape one step at a time and position a plurality of electronic components affixed to the tape at the positions of the automatic assembly machine. Conventional technology as a one-pin component supply device is disclosed in Japanese Patent Application Laid-open No. 58-53888 and No. 58-5.
It is shown in Japanese Patent No. 3889. In this known technology, when a taping feeding unit serving as a feeding means transports the tape one step at a time and positions the electronic component at a predetermined position, the first electronic component is transported to a predetermined position. Since it is necessary to hold the tape, the spherical tip of the pin is configured to constantly press down on the tape by the elastic force of the spring.

[Problem that the invention seeks to solve]

In the above conventional technology, the tip of the pin always presses down the tape, but when an external force other than the taping feeding unit as a feeding means is applied to the tape, the tip of the pin is formed in a spherical shape, so the tape is pressed down. There is a problem in that the tape is deviated in the transport direction, and as a result, the tape becomes slack, making it impossible to transport the tape accurately.

In view of the above circumstances, an object of the present invention is to provide a taping component supply device that can prevent the tape from shifting even if an external force other than the feeding means is applied to the tape.

[Means for solving problems]

In the present invention, the feeding means includes a tape feeding mechanism and a tape holding mechanism, which are respectively disposed at different intermediate positions on the tape conveying path.

The tape feeding mechanism includes a pin that can fit into a hole in the tape, a first driving body that moves the pin toward the hole in the tape, and a first driver that moves the pin in the tape transport direction when the pin and the hole in the tape are connected. and a second driving body for causing the movement. On the other hand, the tape holding mechanism is...

It has a pin that can fit into a hole in the tape and a driver that moves the pin toward the hole in the tape.

When one of the pins of the tape feeding mechanism and the pin of the tape holding mechanism is fitted into a hole in the tape, when the fitting between the pin of one pin and the hole of the tape is released, the pin of the other one is fitted into the hole of the tape. The pins are fitted into holes in the tape, and one pin is fitted into the holes in the tape when the other pin is released from the hole in the tape.

[Effect]

By fitting the pin of the tape feeding mechanism of the feeding means into the hole in the tape and moving the pin when the pin and the hole in the tape are aligned, the tape is conveyed and the parts are positioned.

In that case, when the pin of the tape feeding mechanism and the hole of the tape are disengaged, the pin of the tape holding mechanism is fitted into the hole of the tape by its driving body, and the pin of the tape holding mechanism and the hole of the tape are also disengaged. When the fitting is released, the pin of the tape feeding mechanism fits into the hole of the tape, so the tape is always held by either the pin of the tape feeding mechanism or the pin of the tape holding mechanism. Therefore, since the tape is always held, even if an external force other than the feeding means is applied to the tape, the tape will not shift, and the tape can be accurately transported.
