Description

Electronic component conveying method and device

The invention relates to a conveying method and device, in particular to an electronic component conveying method and device which enables electronic components to be fed into the measuring groove of the measuring plate through the feeding mechanism through the feeding mechanism.

Conventional electronic components, such as light-emitting diodes (LEDs) or passive components, are usually measured for physical characteristics after production to classify or package the electronic components. As a transport mechanism, a large number of electronic components to be tested are placed in a vibrating feed mechanism, so that they are transported in sequence to the receiving grooves arranged around the circumference of the measuring disc, and the transport flow path is intermittently rotated. Displacement transportation, while intermittently staying in each workstation on the transportation flow path to perform polarity measurement, polarity steering, electrical measurement, packaging, sorting, etc.; wherein, there is a separate Blow the positive pressure and negative pressure air holes. When the first electronic component is close to the container, the negative pressure of the container will quickly separate the first electronic component from the second electronic component and make the first electronic component The component is sucked into the container; and when the first electronic component is sucked into the container by negative pressure, a separation pin will rise outside the container to ensure that the first electronic component will not leave the container and block at the same time The second electronic component prevents the measuring disc from being unable to rotate due to the obstruction of the electronic component.

However, with the gradual miniaturization of electronic components, while the first electronic component is sucked into the container by negative pressure, the second electronic component is also easily moved toward the container by the negative pressure suction, resulting in two electronic components Unable to separate. In this case, when the separation pin is raised, it will hit the second electronic component and cannot be raised completely, resulting in the generation of abnormal signals. Abnormal signal, the system will first lower the separation needle away from the feed rail, then blow positive pressure from the air hole of the container, and blow all the electronic components to the side of the separation needle away from the measuring plate, and then re-execute the above-mentioned transportation procedure, but The re-transported electronic components may still maintain the aforementioned inseparable situation, and then an abnormal signal occurs again, which eventually leads to the need to suspend the process first and manually eliminate it manually. This undesirable event occurs, which greatly reduces the efficiency of the operation.

It is the object of the present invention to provide an electronic component conveying method that can reliably separate adjacent electronic components.

Another object of the present invention is to provide an electronic component conveying device capable of reliably separating adjacent electronic components.
