Electronic component steering device and method thereof for preventing trimming

The present invention relates to a steering apparatus and a method thereof for preventing trimming, in particular, after detecting the polarity of an electronic component on an intermittent transport flow path, moving the electronic component out of the intermittent transport flow path for steering, and then moving to intermittent handling The flow path and the electronic component steering device that is prevented from being sheared by the polar steering mechanism during the removal or removal of the electronic component and the method of preventing the trimming thereof.

Conventional electronic components, such as passive components or light-emitting diodes (LEDs), usually perform physical property detection and electrical measurement after output to perform good product packaging and classification of defective products. The measuring discs with a plurality of detecting or measuring workstations are used as the transporting mechanism, so that the electronic components to be tested are placed in a large amount in the vibrating feeder, and are sequentially arranged in a random manner to be arranged in the outer circumference of the measuring disc. In the carrier, the intermittently rotating transport flow path is displaced and transported, and intermittently stays in each detection or measurement workstation for polarity detection, polarity steering, electrical measurement, packaging, classification, etc.; Since the electronic components are arranged in the vibrating feeder when they enter the peripheral groove of the measuring disc, they can only shape the electronic components in the shape of the conveying direction, and it is impossible to determine the electronic components to be transported. The polarity (anode or cathode) is arranged to be transported outwards or inwards, so after the polarity detection workstation detects the electronic components, the polarity alignment process is performed, and the polarities of the electronic components are oriented. In a direction, the mechanism or instrument for the next electrical measurement can take the correct polarity for correct measurement; when detecting the polarity, if the direction of the electronic component placed before the conveyance is sent, the polarity detection is displayed as Correctly, the transport mechanism will cause the electronic component to pass directly through the polarity steering mechanism during the movement; if the polarity of the electronic component before the transport is opposite to the preset, it is discharged from the test tray to the outside of the test disk. It In the polar steering mechanism, after the steering, the electronic component with the correct polarity is sent back to the measuring tray to perform the subsequent electrical measurement operation procedure.
