Description

Carrier tape cleaning method and device

The present invention relates to a cleaning method and device, in particular to a cleaning method and device for cleaning a carrier tape used to transport electronic components through an intermittent moving flow path.

According to, in the packaging of electronic components such as passive components, light-emitting diodes, etc., carrier tapes with continuous intervals are often used. The pinholes arranged at continuous intervals on one side of the carrier tape are used to drive the pins on the pin wheel. While the pin wheel drives the carrier tape to move intermittently, the electronic components to be packaged are implanted in the carrier, and the slot above the carrier is sealed with a film. There are standard electronic components in each of the slots. Therefore, before the film is encapsulated, the carrier tape will be inspected by an Automated Optical Inspection (AOI) device. The inspection items can be, for example, whether the appearance of the electronic components in the slot meets the standard or whether there is a shortage of material in the slot. If the standard is not met, replace the electronic components in the slot.
