Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an automatic electronic component insertion device, and particularly to one that automatically mounts electronic components onto a printed circuit board or the like.

[Prior Art] An automated electronic component insertion device is used to mount electronic components on a printed circuit board or the like.

Conventionally, this type of electronic component insertion device generally has the following features:
Many of them consist of a component storage section, an insertion section, and a board positioning section.

Here, as the insertion part, there are those that limit the parts to be inserted, and those that can handle multi-shaped parts.

Examples of the former include DIP-IC insertion machines,
There are radial parts insertion machines, axial parts insertion machines, etc. These are all specialized machines that handle only one type of part.

The latter type is equipped with a plurality of types of insertion heads, from which the one suitable for the shape of the part is selected and used. The types of insertion heads are prepared in advance depending on the shape of the parts to be handled.

By the way, when handling parts having lead terminals with the conventional apparatus as described above, a preliminary work of shaping the lead terminals in advance is indispensable. However, if the lead terminals are pre-shaped in advance, the shaping process makes it difficult to transfer the components within the electronic component automatic insertion device, and the components are not supplied to the component storage section in the device. In many cases, the inserted parts could not be transported to the insertion position. For example, in order to mount a component having lead terminals in a floating state on a printed circuit board, it is necessary to shape the lead terminals into a somewhat complicated bent shape. However, since the lead shape of the lead-processed component is complicated, it is extremely difficult to transport the lead to the insertion position. This is also a major cause of deteriorating the operating efficiency of this type of device.

Conventional electronic component loading devices have the above-mentioned drawbacks.

[Summary of the invention]

This invention was made in order to improve the conventional drawbacks, and by providing a lead shaping machine between a component take-out transfer machine that takes out electronic components from a component storage section and a component insertion machine, it is possible to handle electronic components of various types and shapes. An object of the present invention is to provide an electronic component automatic insertion device that can automatically insert lead terminals of electronic components in accordance with desired insertion specifications.
