Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for aligning electronic parts used to judge the external shape of electronic parts that are classified into polarities by changing the external shape of electrode parts and supply the same polarities in the same direction. It is about.

In the following description, an electronic component aligning device will be described by taking a chip type tantalum electrolytic capacitor having a groove at one end as an example, but the present invention is not limited to this chip type tantalum electrolytic capacitor. However, the same can be applied to other electronic components in the same manner.

[0003]

2. Description of the Related Art With the progress of miniaturization, thinning, and high-density mounting technology of electronic devices, electronic parts are rapidly becoming chips.

Conventionally, in this type of aligning device for a leadless electronic component, for example, a chip type tantalum electrolytic capacitor, vertical and horizontal alignment is performed using a parts feeder, and the shape is recognized outside the parts feeder using an image processing device. The polarity was determined by this method, and the ones with different polarities were wiped off with air to eliminate the polarity and aligned for polarity, and then sent to the next step.

[0005]

However, the above-described conventional electronic component aligning device has a problem that the electronic component aligning device is expensive because the image processing device is used for recognizing the polarity. Further, there is a problem that the accuracy of the polarity determination is poor and that many are eliminated after the polarity determination, and in order to supply the aligned chip type tantalum electrolytic capacitors, the productivity and the alignment capability are low and the productivity is poor. Furthermore, there was a method of returning the ones of different polarities into the parts feeder again, but this was uncommon because the device was complicated.

SUMMARY OF THE INVENTION The present invention solves the above conventional problems and provides an electronic component aligning device which has an excellent capability of aligning electronic components with a simple structure and having a high alignment capability. It is intended.

[0007]

In order to solve the above-mentioned problems, an electronic component aligning apparatus according to the present invention is a parts feeder which sequentially inserts a plurality of electronic components each having a groove portion at one end for displaying a polarity and sequentially conveys them. When recognizing the direction of the groove of the groove part of the electronic parts arranged in the electronic part conveying path of this parts feeder and sequentially conveyed, and judging that the direction of the groove is not the predetermined direction, the electronic parts are put into the parts feeder. The first determination unit for discharging and the front-back direction of the groove are recognized by recognizing whether the groove of the electronic component, which is also arranged in the electronic component conveyance path of the parts feeder and has passed through the first determination unit, is front or rear with respect to the traveling direction. And a supply unit that supplies the electronic component that has passed through the second determination unit to the next process. Did It is.

[0008]

With this configuration, a device for returning the electronic components not aligned in a predetermined direction into the parts feeder is unnecessary, and the drive source is air, the parts feeder, and the motor, which is a very simple structure. Not only that, all the electronic components supplied from the same device are surely aligned and supplied, so that the production capacity can be improved.
