Description

Electronic component sorting device

The present invention relates to a sorting device, and more particularly to an electronic component sorting device for classifying electronic components after detecting physical properties thereof.

According to the general electronic components, because of their different physical properties, they often need to be packaged or sorted through the process of detection and sorting. Due to the miniaturization and large quantity of electronic components, the devices used for detection and sorting must be provided quickly. With precise transport, these detected and sorted electronic components such as passive components or LED light-emitting diodes.

In the prior art, when the test is performed, a test wheel which can be intermittently rotated is used, and a groove having an equally spaced recess is arranged in the circumference of the test disc, whereby the transport channel of the self-vibration feeder carries the detected component to intermittently rotate. Road transport, after passing through the procedures of multiple test stations, according to the physical characteristics detected by them, it is discharged to different pipelines for transport to a specific collection box for collection; however, before the test discs enter different pipelines, A sorting mechanism is classified according to the detection result of the detecting component. The sorting mechanism usually adopts a concave spherical distributing disc with a plurality of holes on the surface, and a dispensing head located above the center of the concave spherical distributing disc is used for corresponding holes. One by one.

However, the sorting mechanism adopts a concave spherical distribution disc with a plurality of holes on its surface. Since the concave spherical shape itself is a three-dimensional space of three-dimensional displacement, the accuracy of the roundness of the concave spherical shape must be very high, otherwise the dispensing head and its surface are each A clearance occurs between the holes, which makes it easy for the extremely small measuring element to leak or jam. At the same time, the driving mechanism for operating the dispensing head should be displaced in the concave spherical three-dimensional space, and the complexity of the mechanism is The accuracy is also relatively high, which increases the cost; therefore, some sorting machines use a plurality of holes arranged in a plane configuration and in an arc shape. The distribution disk and the distribution head are curved and swung over the arc-arranged holes for the distribution of the components to be tested.

However, a distribution plate that arranges a plurality of holes in a planar configuration and in an arc shape is often provided with a driving member that drives the displacement of the carriage, such as a motor, on the carriage on which the dispensing head is disposed, which causes the weight of the motor to cause sliding of the sliding seat. The speed is affected, which affects the distribution speed of the distribution head! On the other hand, if the mechanism for driving the slide to make the horizontal and vertical displacements of the X and Y axes occupy too much space of the machine, the area of the distribution plate is relatively limited, and of course, the number of distribution holes that can be disposed thereon is also limited. How to simplify and properly arrange the configuration of the drive mechanism is the key! On the other hand, since electronic components for detecting sorting, such as passive components or LED light-emitting diodes, are generally performed, they generally have a considerable degree of dust, and these dusts are easily dropped into the sorting mechanism with a large number of detection conveyance processes. And caulking between the dispensing head and the concave spherical surface of the distribution plate to cause a jam.

Accordingly, an object of the present invention is to provide an electronic component sorting apparatus which is simple in sorting mechanism and low in cost.
