Tape and reel feeder is one of the most commonly used in SMT machine feeder, traditional structure mode has the wheel, claw type electric, pneumatic and more spacing, now has developed into high precision dynamic, high precision dynamic contrast with traditional structure mode, transmission precision feeding speed faster, higher, more compact structure, performance is more stable, greatly improving the production efficiency.
The IC tray feeder can be divided into single-layer structure and multi-layer structure. The single-layer pallet feeder is directly installed on the feeder rack of the mounting machine and occupies a number of chills. It is suitable for the pallet type material which is not much. Multi-layer pallet feeder material has multi-layer automatic transmission tray, small space, compact structure, suitable for more pallet material, tray components are all kinds of IC integrated circuit components.
The Pipe feeders usually use vibration feeders to ensure that the components in the pipe continue to enter the drawing position of the sticker head. Generally, PLCC and SOIC are fed in this way.Pipe feeder has the characteristics of good pin protection, poor stability and standardization, and low production efficiency.
Feeder bulk, also known as vibrating feeding device material, the way it works is the components freely into molding plastic box or bag, by vibrating feeder or components in turn into the SMT machine feeding tube, this way is usually used in MELF and small semiconductor components, shape is only applicable to nonpolar rectangular and cylindrical components, and does not apply to polar components.
