Abstract

PURPOSE:To realize an electronic component inserting apparatus having excellent productivity by solving low productivity of a long time due to visual recognition of a state of a component insertion hole by a visual recognition unit at the time of an insertion error in the apparatus for mounting an electronic component on a printed board. CONSTITUTION:An insertion detection sensor 8 is mounted on an anvil 7 to thereby detect presence or absence of a lead in a component insertion hole of a board by using an insertion detection signal to be output in the case of cutting of the lead as information. If there is no lead, an insertion error is judged to automatically execute a recovery to continue an operation. In the case of an insertion error due to remaining lead, an insertion error impossible for automatic recovery is judged to stop an operation. Thus, since it is not necessary to use a visual recognition unit 6 at every time, a time required for the automatic recovery can be largely deleted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component inserting apparatus used for automatically incorporating various electronic components into a printed circuit board or the like to form a predetermined electric circuit.

[0002]

2. Description of the Related Art Conventionally, predetermined electronic component insertion holes formed in a printed circuit board or the like for automatically incorporating various electronic components in a circuit board for mounting components such as a printed circuit board to form a predetermined electric circuit. After inserting the lead wire of the electronic component into the, the excess lead wire of the electronic component is cut, and the electronic component automatically performs a series of operations of clinching the lead wire to prevent the electronic component from falling off the printed circuit board. An insertion device is being used.

FIG. 6 is a flow chart for explaining the operation of the above-mentioned conventional electronic component inserting apparatus. The electronic components are supplied and taken out, and the lead wires of the electronic components are inserted into the component insertion holes of the separately provided printed circuit board. After that, the excess lead wire is cut, and the lead wire is clinched to complete a series of operations.

After that, as shown in FIG. 7, it is checked whether or not the next electronic component can be inserted by checking after the electronic component has been inserted.
As disclosed in Japanese Laid-Open Patent Publication No. 799, the recognition camera of the visual recognition unit is used to project the component insertion hole of the board in which the insertion error has occurred, and the visual recognition is used to judge and continue the recovery operation, or It used to stop the equipment.

[0005]

However, in the above-mentioned conventional electronic component insertion apparatus, when the insertion error is made, the visual recognition unit is always used to perform the visual recognition and then the automatic recovery is performed. In addition to spending a lot of time on the recognition camera that recognizes the component insertion hole and the recognition processing time, it is determined that insertion is not possible when there is dust or a mis-inserted electronic component on the component insertion hole. However, there is a problem that the operating rate is poor and the productivity is poor because the device stops.

The present invention solves the above conventional problems and provides an electronic component inserting apparatus capable of improving the operating rate and productivity by accurately determining the mounting state of electronic components on a substrate. It is intended.

[0007]

In order to solve the above-mentioned problems, an electronic component inserting apparatus according to the present invention detects an insertion of an electronic component mounted on a board into an anvil portion which cuts off excess lead wires and clinches the tip portion. With the sensor attached, the insertion detection signal output when cutting and clinching the lead wire in the anvil section is used as information to detect the presence or absence of the lead wire in the component insertion hole of the board by the insertion detection sensor. If there is no lead wire in the insertion hole, it is judged as an insertion error and recovery is automatically performed to continue the work.If there is an insertion error with a lead wire remaining, it is judged as an insertion error that cannot be automatically recovered. Then, the operation is stopped.

[0008]

With this configuration, it is possible to easily detect the insertion state of the lead wire of the electronic component into the component insertion hole of the board by the insertion detection sensor, and it is not necessary to use the visual recognition unit as in the conventional case. It becomes possible to make an accurate judgment in a short time, and it is possible to greatly improve the operating rate and the productivity.
