Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component supply device for inserting electronic components into a printed circuit board in a printed circuit board assembly apparatus for mounting electronic components onto a printed circuit board, and particularly to a component supply device for inserting electronic components into a printed circuit board. Electronic components are pasted at predetermined intervals on only one side of a feeding tape and transported. The electronic components are cut from the tape one after another, transported above the printed circuit board, and inserted into predetermined insertion holes provided in the printed circuit board. This relates to a supply device.

In a conventional electronic component supply device for inserting radial taped components, when cutting the lead wire of the taped fin component with a cutter, the electronic component is held by a holding means and then cut. In order to insert it into a printed circuit board, it is transferred to a chuck device and inserted, and the holding means that holds it when cutting the lead wire transports it to the chuck device and changes the posture of the electronic component from the posture when cutting to the posture when inserting. It was normal.

Therefore, it involves operations that tend to become unstable, such as changing the grip of electronic components, and the structure of the platform is also complicated.

It is an object of the present invention to eliminate the above-mentioned drawbacks and to enable a single chuck device to perform everything from cutting lead wires of electronic components to changing their posture and inserting them into printed circuit boards.

In order to achieve the above object, the present invention provides an electronic component insertion device including a sliding body that is guided by a main body and slides in the vertical direction, and a sliding body that is provided at the lower end of the sliding body and that is perpendicular to the sliding direction of the sliding body. A chuck device including a support shaft, a chuck device in which gripping claws that are supported by the support shaft so as to be spreadable and hold the electronic component protrude in a direction perpendicular to the support shaft, and a mechanism for rotating the chuck device about the support shaft. At the rising end of the sliding body, the clamping claws of the chuck device face the electronic component cutting position of the tape feeding device, and as the sliding body descends, the chuck device is rotated to move the clamping claws onto the printed circuit board. They were made to face each other.
