To be able to mount components delivered on either reels, in sticks or trays you need different component feeders to do so.
Below you see the different feeder types and the feeder cart that is available for the YSM20 and YRM20 pick and place machines.
The production efficiency and capacity of the entire SMT line are determined by the placement machine. There are also high-speed, medium and low-speed (multi-function) machines in the industry. The placement machine is controlled by the placement cantilever. The suction nozzle picks up the components, and sticks different components to the designated pad positions on the PCB; then how the suction nozzle picks up the components is achieved through the feeder that I will tell you next.
The feeder of the placement machine has a variety of styles. The following will mainly introduce several types.
Cassette Feeder, Tape Feeder, Tube Feeder, Tray Feeder
belt feeder
The belt feeder is one of the most commonly used feeders in the placement machine. The traditional structure methods include wheel type, claw type, pneumatic type and multi-pitch electric type. Now it has developed into high-precision electric type, high-precision electric type and traditional type. Compared with the structure, the conveying precision is higher, the feeding speed is faster, the structure is more compact, and the performance is more stable, which greatly improves the production efficiency.
Strip material basic specifications
&#;&#; Basic width: 8 mm, 12 mm, 16 mm, 24 mm, 32 mm, 44 mm and 52 mm and other types;
KF-SMT supply professional and honest service.
&#;&#; Ribbon spacing (adjacent element center to center): 2 mm, 4 mm, 8 mm, 12 mm and 16 mm;
&#;&#;·There are two kinds of ribbon-like materials: paper-like and plastic-like;
Tube feeder
Tube feeders usually use vibrating feeders to ensure that the components in the tube continue to enter the pick-up position of the placement head. Generally, PLCC and SOIC are fed in this way. The tube feeder has the characteristics of good protection of component pins, poor stability and standardization, and low production efficiency.
Cassette Feeder
The cassette feeder, also known as the vibrating feeder, works by freely putting the components into the molded plastic box or bag, and feeding the components into the placement machine in turn through the vibrating feeder. It is suitable for Non-polar rectangular and cylindrical components, but not suitable for sequentially feeding components into the placement machine via a vibrating feeder or feed tube, this method is usually used for melting polar components and small profile semiconductor components, suitable for polar components. sexual element.
Tray Feeder
Tray feeders are divided into single-layer structure and multi-layer structure. The single-layer tray feeder is directly installed on the feeder rack of the placement machine, occupying multiple positions, which is suitable for the situation that the tray material is not much; the multi-layer tray feeder has multiple layers of automatic transfer trays, which takes up less space , The structure is compact, and most of the components on the plate are various IC integrated circuit components.
