SUMMARY OF THE INVENTION However, in the above-described method, an intermittent feed mechanism must be provided for each of the component supply devices, and when supplying various types of electronic components, the intermittent feed mechanism is adjusted according to the type. Therefore, it is necessary to prepare a component supply device with a tag, which has increased the cost.

Further, in the above-described method, when supplying various types of electronic components, a method of arranging a large number of electronic component supply devices in a horizontal direction, moving the electronic component supply devices together, and switching a component to be inserted is used. Since the electronic component is held horizontally in the electronic component supply device and is intermittently fed, the moving distance for switching the component to be inserted is long, and the switching takes a long time, and the entire insertion device takes a long time. There is a problem that the types of components that can be mounted are greatly restricted due to the size.

As a solution to this, we have proposed a means as shown in Japanese Patent Application No. 63-136389. However, even in this case, there is a problem that the transfer device and the component holding device must be prepared according to the taping width of the series of electronic components.

In view of the above problems, the present invention reduces the work of exchanging a transfer device and a component holding device according to the taping width of a series of electronic components, and allows mounting of various types of electronic components with a single device. It is intended to be.

Means for Solving the Problems In order to solve the above problems, an electronic component insertion device of the present invention cuts a component holding unit that holds a series of electronic components taping electronic components and a tape of the series of electronic components. A transfer portion having a tape cutting portion, a pair of holding claws for simultaneously holding the tape and the lead wire of the electronic component, and an insertion portion for cutting and bending the lead wire and guiding and inserting the lead wire to a predetermined hole in the substrate; And a fixing portion that bends the lead wire under the substrate and fixes the electronic component to the substrate. The transfer portion includes a pair of the electronic components taped on the electronic component in accordance with a taping width of a series of electronic components. The pawl pitch is provided to be switchable.

The component holding unit has a pair of locking claws for positioning by contacting the lead wires of the electronic component, and a pair of holding claws for pressing the tape of the electronic component and holding a series of electronic components. The pitch of the pair of locking claws and the pair of holding claws can be switched according to the taping width of the series of electronic components on which the electronic components are taped.

The present invention reduces the work of exchanging the transfer device and the component holding device according to the taping width of the series of electronic components by the above-described electronic component insertion device, and enables one type of device to connect various types of electronic components. Mounting becomes possible.
