What Is SMT Placement Machine Feeder

According to the feeding method, the common ones are

        1. Belt feeder,

        The belt feeder is a standard feeder commonly used in the feeder of 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 Compared with the traditional structure, the transmission accuracy is higher, the feeding speed is faster, the structure is more compact, the performance is more stable, and the production efficiency is greatly improved.

        The basic width of the strip material is: 8mm, 12mm, 16mm, 24mm, 32mm, 44mm, 52mm and other types, with spacing of 2mm, 4mm, 8mm, 12mm and 16, etc.; the diameter of the reel is 7 in and 13 in. .

        2. Tray feeder, 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; the multi-layer tray feeder The material has a multi-layer automatic conveying tray, which takes up 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, it is necessary to keep the exposed components of the large tube corners to prevent damage to the mechanical and electrical properties during transportation and use. When using TQFP, PQFP, BGA, TSOP and SSOPs components in the tray, the tray size can reach 150mm x 330.2mm and the height is 25.4mm. What’s interesting is that the tray feeder can not only supply the pick-up components of the placement machine, but also serve as a potential throwing station for valuable components.

        3. Tubular feeder

        Tubular 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 use this method to feed. The tubular feeder has the advantages of good protection of the component pins, poor stability and standardization, and low production efficiency.

        4. Bulk material box feeder (Qihe 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 feeding tube Mounter, this method is usually used for MELF and small-profile semi-conductor components. It is only suitable for rectangular and cylindrical components, not for sexual components. Features: Vibration feeder is more expensive.

        5. Vibration Feeder Vibration Feeder is a special feeder, which needs to be customized. The current production is better.
