Description

Technical Field

[0001] The present invention relates to the technical field of SMT patch equipment, and in particular to a material tape splicing device and an SMT material tape unsplicing machine. Background Art

[0002] SMT is the abbreviation of a series of process flows based on PCB (Printed Circuit Board). PCB (Printed Circuit Board) is the printed circuit board. SMT is the abbreviation of surface mount technology (Surface Mounted Technology), which is the most popular technology and process in the electronics assembly industry.

[0003] In the SMT patch process, the material tape can be delivered to the patch machine through the feeding trolley loading tray so that the patch machine can complete the patch work. Usually, when the material tape of the old tray in the material bin of the feeding trolley is about to be exhausted, a new tray needs to be taken out, and the material tape head of the new tray and the material tape tail of the old tray are connected through the material disassembly machine, and then sent to the material bin of the feeding trolley to continue loading the old tray.

[0004] The existing strip splicing machine's material stripping device usually includes a base, a first conveying assembly, a material splicing assembly, and a second conveying assembly. The first conveying assembly, the material splicing assembly, and the second conveying assembly are all fixedly mounted on the base. The first conveying assembly is used to temporarily store the material strip on the old material tray and convey the tail of the material strip of the old material tray to the material splicing assembly. The second conveying assembly is used to convey the head of the material strip of the new material tray to the material splicing assembly. The material splicing assembly is used to bond the tail of the received material strip of the old material tray to the head of the material strip of the new material tray. This type of material strip splicing device will interfere with the old material tray during the splicing process because the material splicing assembly and the second conveying assembly are fixed to the base. The old material tray needs to be moved to an empty position through the material splicing assembly and the second conveying assembly to temporarily store the material strip on the old material tray. This causes the old material tray to have a longer travel distance, affecting the efficiency of the material strip splicing. Summary of the Invention
