Description

TECHNICAL FIELD

[0001] The utility model relates to SMT material band processing technical field, especially a kind of SMT material receiving device. BACKGROUND

[0002] SMT (Surface Mounted Technology) is a kind of printing process of PCBA circuit board, which installs various pinless, short leadless components on the surface of PCB or substrate, and then completes installation by flow soldering, dip soldering and other ways. The material receiving machine is an auxiliary equipment on the SMT production line, which automatically or manually connects the next material to the material disc before the material in the material disc is used up, to ensure the uninterrupted operation of the production line. The material band butt joint precision refers to the accuracy of the head and tail butt joint of two material bands when the material bands are connected on the material receiving machine.

[0003] In the SMT industry, due to manual operation, equipment precision and other factors, the material band butt joint precision is a common problem.

Insufficient material band butt joint precision will directly reduce the production line efficiency, because frequent material connection errors and alarms will interrupt the production process.
