Do you know which application types are used for SMT placement machine feeders?

The function of the feeder: is to provide the SMC/SMD components to the placement head according to a certain rule and order for accurate picking. It occupies a large position in the placement machine and is an important part of the placement machine and the SMT production line process.

1. Tray feeder

It can be 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 and occupies multiple slots. It is suitable for the situation where there is not much tray material; multi-layer tray feeder The material has a multi-layer automatic conveying tray, which occupies a small space and has a compact structure. It is suitable for situations with a large amount of tray materials. Most of the tray-mounted components are various IC integrated circuit components.

When using pallet materials, you need to pay attention to keeping the exposed components of the large tube corners to prevent damage to the mechanical and electrical properties during transportation and use. When TQFP, PQFP, BGA, TSOP and SSOPs components are used in the tray, the tray size can reach 150mm x 330.2mm and the height is 25.4mm. And the tray feeder can not only supply the pick-up components of the placement machine, but also can be used as a potential throwing station for valuable components.

2. Belt feeder

The belt feeder is one of the most commonly used feeders in the placement machine. The traditional structure methods include wheel, claw, pneumatic and multi-pitch electric. Now it has developed into high-precision electric, high-precision electric and traditional Relative structure, higher transmission accuracy, faster feeding speed, more compact structure, more stable performance, and greatly improved production efficiency.

The basic width of the strip material is: 8mm, 12mm, 16mm, 24mm, etc., and the spacing is 2mm, 4mm, 8mm, 12mm and 16, etc.; the diameter of the reel is 7 in and 13 in. .

3. Bulk material box feeder (vibration feeder)

Bulk box feeder, also known as vibrating feeder, its working method is to freely put the components into the formed plastic box or bag, and send the components in order by using the vibrating feeder or the feed pipe into mounting machine, this method is usually used for MELF and small outline semi-conductor components, only suitable for non-polar rectangular and cylindrical components, not for polar components.

4. Tubular feeder

Tubular feeders usually use a vibrating feeder to ensure that the components in the tube continue to enter the pickup position of the placement head. Generally, PLCC and SOIC use this method to feed.
