Suzhou SMD bearing belt

There are two main categories of reasons for component jamming in carrier belt manufacturers:

Component dimensions are too large, or the component is deformed or has burrs;

Carrier belt dimensions are too small, or the component is deformed, has hooks, poor forming, or is poorly designed.

Analysis of causes:

Component-related:

Component dimensions are outside the design range, causing interference with the carrier belt groove, resulting in jamming;

Components are deformed or have burrs, and the location of the deformation or burrs interferes with the carrier belt groove, resulting in jamming;

Carrier belt-related:

Wear of the forming mold causes the forming mold dimensions to become smaller, resulting in interference between the carrier belt groove and the component, leading to jamming;

For example: If the mold is used for a long time without maintenance and inspection, the edges of the mold will wear down, and the bottom edges will become rounded (as shown in the picture below). After forming, the bottom of the groove will be rounded, causing interference between the component pins and the rounded edge of the groove, resulting in jamming.
