Description

Technical Field

[0001] This utility model relates to the field of SMT tape splicing technology, and in particular to a tape conveying mechanism and a tape splicing machine. Background Technology

[0002] SMT (Surface Mount Technology) is a core technology in modern electronics manufacturing and is widely used in consumer electronics, communication equipment, automotive electronics and other fields. The core equipment of SMT technology is the SMT placement machine, which can automatically pick up components and place them accurately on the PCB through an electronic eye recognition device.

[0003] In actual production, when the tape in the pick-and-place machine is about to run out, a tape receiving machine is needed to connect the new tape head in the storage cartridge with the old tape tail in the pick-and-place machine. Therefore, the tape receiving machine is usually equipped with a cartridge for temporarily storing new tape trays. In order to convey the tape head of the new tape tray toward the receiving platform, each cartridge is equipped with a conveying ratchet and a gear. The conveying ratchet is rotatably mounted on the cartridge and coaxially connected with the gear. The feeding drive is used to drive the gear to rotate, thereby driving the conveying ratchet to rotate. The tape head of the new tape tray needs to be manually inserted into the corresponding clamping hole on the tape head. The feeding drive drives the conveying ratchet to rotate, thereby completing the conveying of the tape head of the new tape tray.

[0004] Obviously, each existing material tray clip needs to be equipped with a conveyor ratchet and gears, which is costly; moreover, it requires manual insertion of the teeth of the conveyor ratchet into the corresponding clamping holes on the material belt head, which is inefficient.
