Description

Automatic feeding machine Technical Field The invention relates to the field of electronic element manufacturing, in particular to an automatic feeding machine. Background The packaging process flow of the LED generally comprises a series of production lines such as die bonding, wire bonding, glue sealing, baking, cutting, light splitting, packaging, warehousing and the like. In mass production, a plurality of brackets are connected together, so that the operations of die bonding, wire bonding and the like of a plurality of LEDs can be finished simultaneously. Generally, the LED support after die bonding is loaded in a tray, and then the operator manually places the support in order, and then places the support in a feeding mechanism of a wire bonding machine to prepare a wire bonding process.
