Description

Technical Field

[0001] This utility model relates to the field of chip mounter technology, and in particular to a portable short feeder. Background Technology

[0002] The term "Feeder" is a transliteration of the word "feeder," which is generally translated as a feeder or feeder. It is mainly installed in a pick-and-place machine to provide components for mounting on a PCB board.

[0003] When a pick-and-place machine is working, the raw material tapes are often rolled into reels for easy processing of large quantities of materials. However, in actual production, it is often necessary to process small quantities of materials and produce only a few samples. Due to the small processing volume, direct feeding is not possible during pick-and-place. Users often need to cut the various electronic components from the tape and then feed them through a feeder. Because the existing feeders are inconvenient to disassemble and assemble, and the feeder's limit specifications can only adapt to one type of tape, this feeding method requires constantly changing feeders of different specifications. This is not only cumbersome to operate, but also time-consuming and labor-intensive, seriously affecting the processing speed and indicating room for further improvement. Utility Model Content
