Description

Technical Field

[0001] The present invention relates to the field of automated processing technology, and in particular to a SMT material strip receiving device and method. Background Art

[0002] SMT is the abbreviation of surface mounted technology, which we often call surface mounting technology. It is a PCBA circuit board printing process. In the SMT production process, splicing tapes are usually used to ensure the stability and accuracy of electronic components during the conveying process, reduce the offset and loss of components, and thus ensure the quality of mounting. When the tape runs out or needs to be replaced, if it is not spliced, the production line will have to stop working, which will cause production interruptions and affect production efficiency and costs; by splicing new and old tapes, the continuity of production can be ensured, downtime can be reduced, and production interruptions caused by replacing tapes can be reduced, thereby improving overall production efficiency and reducing production costs.

[0003] However, in the current processing and manufacturing, the splicing of new material tape and old material tape is done by the operator using copper buckles or material films on the production line to achieve uninterrupted operation of the production line. Manual operation not only increases production costs, but also makes the qualified rate of the production line low. The material tape has problems such as inconsistent cutting length and uneven cutting end faces. After the material tape with inconsistent cutting length enters the feeder, it will cause the machine to get stuck due to inaccurate conveying position, which greatly affects the production efficiency.
