Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic component insertion device for inserting electronic components into a printed circuit board.

[Conventional technology]

・In accordance with the printed wiring assembly diagram of the electronic device, the work of inserting and fixing the lead wires of electronic components of the specified type and performance into the lead wire insertion holes whose positions are specified by the printed wiring pattern of the printed circuit board is automated. ing. For example, XY
There is a method in which a printed circuit board placed on a table is moved and parts of different types are sequentially inserted in a specified order.

The parts inserted here are taping parts and DI
This applies to P-type parts. Furthermore, numerically controlled fully automatic insertion machines that can insert various parts have also been developed.
゛ [Problem to be solved] A device that inserts components by moving an at low speed,
It was also easy for human error to occur. In addition, in such H, after the insertion head inserts the component into a predetermined location on the printed circuit board, the clinch head also moves in accordance with the movement of the XY table, clinching the lead wire of the electronic component inserted into the printed circuit board. However, since the movement of the insertion head and the movement of the clinch head were controlled separately, it was difficult to achieve even higher speeds. Furthermore, numerically controlled fully automatic insertion machines can perform work at high speed;
Extremely expensive.

Therefore, an object of the present invention is to provide an electronic component insertion device that is inexpensive and has a simple mechanism, and also allows the clinch head to always follow the movement of the insertion head to ensure reliable insertion and clinch of electronic components. The object of the present invention is to provide an electronic component insertion device that has the following features.

Means for Solving Problem c] In order to achieve the above-mentioned object, the present invention includes an insertion head for inserting an electronic component into a printed circuit board, which is attached to a main body of the device, and the main body of the device is moved at least close to the printed circuit board. The clinch head, which clinches the electronic component glue wires inserted into the printed circuit board by the insertion head, is attached to the main body of the device at a position always facing the insertion head. It is something that

[Effect]

In this invention, since the insertion head and the clinch head are always in opposite positions, each insertion and clinch operation can be performed accurately, and it is cheaper than a numerically controlled XY table, and it can be used in a conventional device using a moving XY table. You can work faster than before.
